Even a Sleeping Bear is Dangerous

-It's Day Six already of the Arcane Parenting Week event, and not being able to decide between today's themes of 'Protective' and 'Mistake' I've chosen to blend them.

A small-time gang decides the best way to secure themselves a reputation is to kidnap someone(s) for ransom...unfortunately for them their targets happen to be the worst possible ones they could have chosen...

Night was beginning to fall, not that it made that much of a difference down in the Lanes, what with the perpetual murk and deep, shifting gloom punctuated by the sickly glow of neon remaining fairly unchanged no matter the time of day.

Lurking in the doorway of a disused shed behind a defunct smoke shop, three young men stood and watched the comings and goings of their 'fellow citizens'. Some time ago they had formally, as much as was notable, formed themselves into a gang called the 'Pit Pirates', though thus far this had done nothing to change their fortunes.

The tallest and oldest, calling himself 'Captain', lazily spun a knife in his fingers, glaring at nothing in particular as he abruptly voiced a thought he'd had for a while, "We need to do something to turn this shit around, really put ourselves on the map ya know?"

"I know, but what?" the shortest questioned as he scratched his ear, "We ain't exactly got a lotta skills..."

"That's why we gotta think of something easy, Crash!" Captain rolled his eyes.

The last, stocky and only a hair shorter than Captain, spoke up, "We could try holding someone for ransom..."

"Yooooo!" the others piped up, Captain standing up straighter, "Skull you're a fuckin' genius! But...no one has much money around here, and we can't exactly go snatch someone from upstairs we'd be dead meat..."

Skull grinned darkly, crossing his arms, "Bet even folks around here would pay up if we took their kid."

Captain and Crash 'oooh'd quietly, and they quickly formed a huddle to lay out their scheme more thoroughly...

"There is no way in hell-"

"Yeah huh! I could totally do it."

"That is way too far..."

The next morning, Vi, Powder, Mylo, Claggor, with Ekko joining them, had in their aimless wanderings along the waterways stumbled upon a broken span of rusted, old support beam jutting out over a tributary of the river, and after some consideration, decided it would be great fun to try and leap from it's end to the opposite bank. The only issue was the length of the jump; even with plenty of room for a running start, it would be a tricky move to land. Luckily there was a ledge of earthen debris below, so even if they failed, they probably wouldn't get too hurt. Probably.

It was a risk several were willing to take, if nothing else for the bragging rights, and the back and forth continued.

"I don't think I can make it..." Powder whined, crossing her arms and backing away.

"It's okay Pow," Vi reassured her, "You can take the long way around."

This only made Powder pout more, and now Claggor spoke up, "Guys didn't Vander just tell us not to do anything reckless for once?"

Mylo waved a hand dismissively and made a 'pfft' sound, "Yeah yeah I know he's being protective and all but...c'mon ya gotta admit that'd be a pretty sick jump to make!"

Ekko planted his hands on his hips and smirked, "I've got no issue with going for it."

None of them noticed the three figures hidden in the deep shadows of fallen timber and metal not too far off, watching closely, waiting for an opportunity to strike.

"The two girls are related...I heard the bigger one call the smaller 'sis'..." whispered Skull, "We should get them both; we nab one and the other will cooperate..."

Captain nodded toward Claggor, "I say we nab that one too...he looks like he'd be the slowest to run."

"What'bout the other two?" murmmured Crash, with Skull responding, "Get the taller one...the smaller one looks like he'd be a slippery little bastard don't bother. Now, we wait for them to be distracted enough..."

All of them backed up to where they calculated they needed to be to make it, and Ekko, insisting on being the first to try, stretched his legs and did a couple warm-up hops before crouching and to the loud cheers of encouragement from his friends barreled forward, reaching the end and propelling himself forward into empty air, the sensation of flight engulfing him in slow-motion...until the joyful cries behind him abruptly morphed into ones of chaotic confusion. He landed hard, rolling and jumping up to turn and see a horrifying sight-

Three men, unknown to him, had appeared and were struggling with the rest of the group; one already had Powder firmly in his grasp, who was shrieking for Vi, Vi trying to fight off the largest of them until the one who held Powder produced a knife and threatened her with it, causing Vi to back down. The last of them had already managed to yank Claggor's hands behind his back and hold him there, the boy trying to fight him off.

Vi whirled and screamed at Mylo, "RUN! GET HELP!"

In a panic, everything happening too fast, Mylo scrambled for the same beam Ekko had crossed, and even with one of the thugs close behind, managed to leap across to join him. He slammed into the dirt, Ekko quickly helping him up and they stared in terror as their friends were swiftly dragged away, still fighting and shouting...

"-so the word is they're considerin' sendin' groups less frequently down here. Somethin' about not bein' neccasary l guess, unless trouble starts brewin...funny aint it." explained Benzo, pouring another drink for himself and the man who'd pulled up a stool to his counter.

Vander accepted the drink with a thankful nod and a shrug, "Long as things keep up this way there's a chance that-"

They were interrupted by the door slamming open and two very out-out-breath youths crashing through, both yelling over each other.

"-they grabbed them we-"

"-no idea why-"

"-just a few minutes ago down by-"

"Whoa whoa, hold on, just a second-" Vander placed his hands firmly on Mylo's shoulders, trying to get him to focus as Benco came around the counter and knelt to look Ekko in the eye to ask, "What happened?"

The small boy was crying but tried to speak clearly, "W-we were by the river and these guys came outta nowhere and grabbed Powder, Vi and Claggor!"

"We don't know why, or who they are, but Vi told us to get help s-so we ran here-" continued Mylo, his breath coming in panicked huffs.

The men gaped at each other in disbelief; there was no way they'd make up or exaggerate something this gravely serious, especially not with how emotionally distraught they were now. Benzo asked, "Do ya remember anything? What did they look like? Did they say anything, like a name or place or why they were doin' it?"

Mylo swallowed hard and glared at the floor, "I remember one thing...they said something about 'finally the Pit Pirates will be taken seriously'..."

Vander's eyes widened a little; he knew the name...one of his many informants had told him of a gang of small-fries who operated out of an abandoned storehouse by the river. They weren't seen as a threat, but more of an annoyance to be dealt with later...but that later had apparently come.

He stood slowly, glowering toward the door as Benzo did the same and went to snatch a gun and a long knife, saying to the kids, "I'm gonna lock the door behind us. Don't you dare open it for anyone. We'll be back soon, with everyone."

"H-how, what? What about us we need to come too-" Mylo started to protest but Vander cut him off.

"You two are staying here." he spoke lowly, in that deep, almost growling tone that firmly said the discussion was over...

Crash peered out a flap of cloth that covered the only window in their 'headquarters' before turning back to his comrades-and their captives. All three of them were seated in chairs with their hands bound behind them, the pink-haired one with extra strong rope because of her tendency to try and punch them, who even now was struggling and flinging curses at them, swearing when she got loose she would 'beat the fuck out of all of them'.

The smallest, also fighting against her bonds, was still crying and the boy had succeeded in moving himself somewhat-but only to topple over on his side.

Captain, seated at a rickety table he was using as a desk and trying to draw up a ransom letter, whirled around, "Shut UP all of you!!"

"This better be worth it..." grumbled Crash.

Skull paced about the room, "It will, it will...finally, we'll be known as bold, and willing to do what it takes-"

"You won't be known as much when we're done..." came a sudden, low voice from the sole doorway.

All three gang members whirled in shock, Captain snapping, "Hey Crash y-you were supposed to be lookout!"

Vi looked up, her face brightening with astonishment, "Vander! Benzo!" as Powder and Claggor took turns shouting out to them in relieved, hopeful pleas. The pair started to stride forward, Crash trying to jump in the way-but with one movement, Vander snatched the smaller man up by the collar and flung him away. They was met with little opposition now save for a lot of shouting as they went and undid all the kids's bonds, helping them to their feet. They threw their arms around him, crying and talking rapidly, and he knelt, gently hugging them all, telling them he was so glad they were okay. Then, his expression hardening to steel, he stood before turning to Benzo.

"Get them home safe. I'll catch up."

"Van...?" Benzo wondered cautiously, recognizing the look in his grey eyes, one he hadn't seen for a long time.

"I won't be long." he replied cryptically.

The kids, having been through enough and even them picking up on the simmering rage in his voice and body language, felt it best to simply comply when Benzo shooed them toward and out the exit.

The only exit. Which Vander had strategically blocked as he now slowly, deliberately, stalked in a half circle around them, cornering his prey with a tight-lipped smile that held far more contempt than amusement. A line had been crossed today, and potential consequences be damned, he would have them know just how far over that line they'd been.

"So...now that it's just us guys, ya wanna tell me what you were doin' messin' with my kids?"

"Shit...shit shit shit!" Skull stammered, his face pale and starting to sweat, "Ah gents we fucked up so bad..."

"W-why?" whispered Crash.

Skull whipped toward him and hissed, "Didn't ya hear what those kids called him?! That's Vander, THE Vander you moron and it was his kids we grabbed!"

"What difference does it make who's they are?" he questioned darkly, taking a couple heavy steps towards them, "They're someone's. And even if they weren't, they're kids...ya don't fuck with kids, mate..."

Now it was Crash's turn to lose all color in his face. They were so, royally, completely screwed; it didn't take a genius to see the utterly merciless ferocity behind those grey eyes, all of it aimed directly at them. Only Captain had seemed to remain somewhat unfazed by this revelation, and as the other two tripped over themselves, literally and figuratively with running their mouths to try and weakly 'apologize', he slowly pulled his knife from it's holder and tried to rush him, raising the blade-

With one swift, brutal motion, Vander snatched his wrist with one hand, pressing down as he slammed his other fist upward on the underside at the elbow, snapping the joint instantly. Captain collapsed on the filthy floor, writhing and clutching his broken limb as the other two looked like they were about to soil themselves.

Crash fell to his knees, "We're sorry okay!? We're super sorry w-we made a big mistake we won't do it again ever!"

"We didn't even hurt 'em or nothing yeah we're sorry!" sputtered Skull.

Vander drew a deep breath, exhaling in a deep growl of barely-contained fury, "I saw them. I saw the bruises and bumps and scrapes. And even so..." he rolled his neck and shoulders, then cracked his knuckles, "Sorry only means somethin' when ya understand what it is ya did wrong and work to correct it. I don't think ya lot fully understand yet without some additional...help."

Benzo sat nervously at his counter, downing another shot of whiskey. He knew, or he hoped, Vander would be okay, it was just how far he'd go he was worried about. He had seen that look in him, the one he hadn't seen in years since he last wore his infamous gauntlets, the one that held only vengeful animosity and single-minded purpose; to pummel anyone in his way.

Abruptly, there was a three, then a brief pause, then two raps at the door, and Benzo immediately got up to open it, praying he wouldn't find a man half-dead or worse there. To his relief, Vander walked in, looking relatively unscathed. He also looked utterly exhausted, but he straightened himself and asked, "Where are they?"

"All relaxin' and decompressin' in my back room. They're okay, just shaken up pretty bad. I cleaned 'em up already and got 'em some tea. They'll be fine..."

Hearing this reassuring news, Vander thanked him for his help, then dropped into his stool and grabbed the entire bottle, downing a generous swallow. Benzo went and sat next to him, wondering uncertainly, "....So?"

"They won't be botherin' anyone again." replied Vander in a flat, tired tone.

"Vander...?" pressed Benzo with a concerned, raised eyebrow, and Vander shook his head.

"No, I didn't kill 'em. I think a small part of me woulda. I don't know. All I know is I made sure I let 'em know they made the biggest mistake of their lives, and if I ever hear 'bout 'em tryin' that shit again, well..." he raised a hand, his blood-covered knuckles now visible, "These ain't hard to clean."

Note

Is it true that Gorbachev never supported Valery Legasov? Did he have a "court" as they say, or did he realize that Legasov was an expert one should listen to?

Thank you for a great ask, Comrade! 💜💛💚 And please forgive me for such a belated answer! And the same goes to all the authors of all the other anon asks I received but have yet to answer - I deeply value each and every one of them and promise to respond to them very soon!

I do think that David Dencik’s Gorbachev, though not without charm, comes across as this kind of annoyed and needy monarch in the show. The real Gorbachev, with all his shortcomings, was a lot warmer - in a folksy kind of way - and much more personable. Look at this photo for example, of a room from which the Politburo meeting room was modeled in the show, and how Gorbachev sits together with the rest of the members, and not at the head table like a king:

And as to your question more directly - I actually have just the kind of a fascinating text here that I think, will speak for itself as far as the extent to which Gorbachev listened to and trusted Valery Legasov. The text is a transcript of the Politburo meeting that took place in the morning of May 5th in 1986 - merely a week after the accident. It actually is kind of a riveting read - a glimpse into how all those decisions had to be made in real time, with only meager - and constantly changing - information available.

I wanted everyone to enjoy it, so I translated the discussion section from Russian (please see below).

Legasov really shines in this meeting and one can easily see just how much respect he instills in people around him. There is a rather amazing passage where Legasov voices his disagreement with Velikhov’s plan on how to drain the water from under the reactor. Gorbachev immediately takes Legasov’s side and approves his plan. He then sends Shcherbina out of the room during the meeting to make an immediate phone call to Chernobyl to instruct them to ditch Velikhov’s plan and start implementing Legasov’s. That was my favorite part.

Legasov also consistently sounds like the calmest person in the room. Just calmly and intelligently doing his job, solving what is essentially a scientific problem. Even from the transcript it is easy to extrapolate how much respect he commands around the table.

I took the liberty to include some of my own notes/comments in the translation as well. And I am happy to answer any questions I can!

@elenatria, @alyeen1, @shark-from-the-park, @drunkardonjunkyard, @green-ann, @valerafan2, @johnlockismyreligion, @attachedtofictionalpeople, @the-jewish-marxist, @potter012

SHCHERBINA: We found ourselves in front of a situation that has not been considered before, which is why there hasn’t been any protocols in place for this type of an occurrence. The very project itself is built upon never allowing such a situation. There was an uncontrollable speeding up of the reactor. Immediately after the accident, there has been a lack of preparedness on-site to evaluate the situation. The Civil Defense did not warn people. Until the evening there were weddings being held in the city. The fire had to be smothered as soon as possible, and the radioactive fallout had to be reduced. 4 thousand tonnes of materials have been dumped at the reactor. We were able to knock the surface temperature down from 500 to 200 degrees. What shall we do beneath the reactor? People have approached the pool. It is possible that there is an opportunity now to release the water.

LIGACHEV: Don’t get ahead of yourself.

RYZHKOV: We’ll need to see about that. The most important thing is to avoid the explosion.

SHCHERBINA: The most difficult thing is deactivation.

(Note: Deactivation refers to the clean-up and burial of contaminated soil and water, etc - LSW)

GORBACHEV: The most important is to deal with the danger that is below.

SHCHERBINA: People are working selflessly.

(Note: It seems like they might all be talking over each other in an agitated manner. Wish we could hear a recording of this - LSW)

LEGASOV: The work is organized the following way: Comrade Shcherbina is in charge of organizing, Comrade Meshkov studies the reasons of the accident and I work on recommendations regarding prevention of the further spread of the fallout. There are also groups in Moscow conducting the analysis.

(Note: Legasov truly shines here, stepping in calmly and intelligently to get the discussion back on track. - LSW)

The considerations regarding prevention of the consequences of the accident that are being voiced in the West should be taken into account. These aren’t just guesswork, but a result of studies, conducted with other past NPP accidents taken into account. We had to do all the calculations on site, because we didn’t have any established protocols in place.

GORBACHEV: Plus in this case, there is water under the reactor.

LEGASOV: This was done to save money, otherwise one would have to build two separate buildings. Minsredmash did not agree with that. If we had 4-5 pipes that would be stretched away from the reactor and into some distance, this would not have been a problem. This is a miscalculation of everyone working in the energy industry.

GORBACHEV: What about the containment structures?

LEGASOV: Considering the force of the explosion that took place, a containment structure would not have saved anything.

GORBACHEV: We need to focus on what comes next.

LEGASOV: 10 hours later, we were able to stop the reactor. But it continues to emit radioactivity, because after a year of being in operation, it has accumulated a lot of isotopes. The heat output of those debris has been 14 megawatt in the first 24 hours, while today it is 8.5 megawatt. This is like burning 60 tons of coal every 24 hours. Besides that, graphite is burning, too. There is 2.5 thousand tons of graphite there in total. One ton burns up every hour. This equals 24 tons per day. The graphite will burn up completely in one-third of a year.

The number one task is to create a way of filtering out the radioactive isotopes. Right now the amount of them that gets emitted into air is 100-fold less than there would be without taking measures to drop sand and other materials on the reactor from the air. The area located in the vicinity of the reactor has been sacrificed, because dumping the materials from the height of 200 meters raised dust, which increased radioactivity near the power plant.

Currently, the mass that has been melted in the reactor is moving downward. This is difficult to control, because there hasn’t been monitoring devices installed that would allow doing that. This is my fault, too. But, not a single NPP in the world has something like that.

(Note: Remarkably, Legasov accepts blame for something he hasn’t even designed. Only that he hasn’t voiced his concern about this highly improbable scenario. Or maybe he did but doesn’t think he did it strongly enough? - LSW)

On the first day after the accident, the temperature of the melted mass was 1100 degrees, while yesterday at 18:00 it was 20 degrees. It goes up by 135 degrees every day.

(Note: “20 degrees” is clearly a typo and should say ~2000 degrees, as a quick calculation can confirm: 1100 + 135 x 7 days = 2045 degrees. - LSW)

Last night, an experiment was conducted: the melted mass fell into water, and there hasn’t been an explosion. However, if the melted mass from the reactor reaches the water below, there will be powerful formation of steam.

The situation continues to be troubling. The reactor needs to be cooled from below. An underground tunnel needs to be created, and liquid nitrogen needs to be delivered via it. In 2-3 days, we need to allow the circulation of air. Yesterday, there were no air drops to enable the draft.

Regarding the potentially dangerous zone. It cannot be larger than 250 kilometers. Within which the active zone would be 30-50 kilometers. Our institute has previously considered a “Backstop” scenario, concerning this problem. So we have exact calculations on that account.

GORBACHEV: What would happen if the fuel reaches the ground water?

LEGASOV: This is where Velikhov and I could not find common ground. The pool needs to be emptied of water by pumping, not by shooting at it to pour it out.

GORBACHEV (to SHCHERBINA): We should let the site know, so they don’t shoot at it.

(Comrade SHCHERBINA steps out)

LEGASOV: And as for adding the concrete layer, that’s the final operation.

GORBACHEV: What about the remaining three blocks?

LEGASOV: The first two are in working condition. Barring another explosion, they will be fine. As for the third block, it might catch fire if there is another emergency.

GORBACHEV: Should we invite the foreigners? We shouldn’t do it in vain. But if we have to, then don’t be deterred by it.

LEGASOV: We were shown the cipher telegrams regarding this. Only two things were unknown to us: the French foam and the remote controlled robots from West Germany. So there is no need to send a general SOS message, whereas all the ideas originating overseas should be sent to the group for consideration.

RYZHKOV: If the strategy with pumping the water out via a pipe works, can the same pipe be used to pump the liquid nitrogen in?

LEGASOV: Yes. But it doesn’t cancel out the idea of a tunnel.

RYZHKOV: We should do both.

SHCHERBINA: I was just informed that the water pumping has begun.

(Note: looks like Shcherbina returned to the room after calling the site with this information. So, within this brief time span, Velikhov’s plan of shooting at the bubbler pool (with some sort of a projectile?) was rejected and Legasov’s idea was not only approved by Gorbachev, but actually started being implemented in real time. Amazing. - LSW)

(Note: another interesting takeaway is that they were arranging to bring Joker from West Germany way earlier than it was portrayed in the series. - LSW)

ALEXANDROV: Legasov reported everything correctly. Regarding the foreign assistance: it would be good to bring doctors who specialize in bone marrow transplants.

ALIEV: This type of a specialist is already working.

(Note: this must be Robert Gale. - LSW).

LIGACHEV: Is there a possibility of a chain reaction?

ALEXANDROV: There is. But not an explosion, i.e. a momentary process. But there would be major steam generation.

SLAVSKY: Our Ministry is participating in limiting the consequences of the accident. My first deputy is there on site. One of the reasons for what has happened is that the Atomnadzor (Note: a nuclear watchdog/inspection agency - LSW) has done zero work. What is being done right now is correct. No further suggestions.

BREZHNEV (minister of transport infrastructure): Together with Comrades Shchadov and Usanov we went on site yesterday to survey the situation with approaching the water through drilling. The start of pumping is eased by its location. After the pumping, one must start pumping the clay-concrete mix. The drilling is complicated by the fact that the reactor cannot be approached to a distance closer than 250 meters. We have arranged with the military for them to deactivate the area so we could approach to a closer distance, 50 meters.

GORBACHEV: We should be picking up the pace. We should be working not only as if this was a wartime situation, but a nuclear one - around the clock.

RYZHKOV: Comrade Brezhnev should return on site and organize this work.

GORBACHEV: Yes.

GROMYKO: What’s the percentage of the fallout that enters the atmosphere?

LEGASOV: The SO is exceeded 22-fold. There will be zirconium. First, there was iodine coming out, and now it’s the rare earth minerals. The zone in the radius of 30 kilometers is dangerous. Iodine decays halfway in 8 days, and after 80 days there will be nothing left.

SEDUNOV (Deputy Chairman of Goskomgidromet): We are watching the situation with radiation from airplanes and the land sites. The spread of radioactivity depends on wind direction. First, the cloud went north, then west and south. There was a spread of radioactive air into Poland, Scandinavia, then into Romania and Bulgaria, yesterday - into Turkey. In Kiev, its level increased 80-fold above background, this morning it is 45-fold. A norm for the public is considered 10-fold above background over a year. In Minsk and Lithuania it’s 3-fold. In the North Caucasus, 2-fold. We suppose that in Kiev, it will start receding. But if the wind changes, the cloud can head toward Moscow.

(Note: Goskomgidromet is the weather forecasting agency. - LSW).

SHCHERBITSKY: Someone confused roentgens and milliroentgens.

(Note: not sure what he is referring to? - LSW).

SEDUNOV: It is important to watch the isotope content of the precipitation. Iodine goes into milk. Today that’s where most of the danger is coming from.

GORBACHEV: What to do with the cattle?

SEDUNOV: No need to destroy it. The Kiev water reservoir may become polluted.

LYASHKO: The water probes are being taken every hour. Radioactivity was only found in upper parts of the Pripyat’ river. We banned the public from drinking water from open sources there.

SEDUNOV: In Moscow everything is normal so far.

SHCHADOV (minister of coal industries): It is dangerous to break through the wall. Water should be pumped out and then the mix should be pumped in. If necessary, we’ll dig under the building.

(Note: Shchadov circles back to talking about the water problem and backs Legasov’s strategy. - LSW)

AKHROMEEV (deputy defense minister): Task number one is controlling the radiological situation. We started the deactivation of roads and other sites. Three thousand people are working on it. Today we will finish preparing the deactivation plan and report to the working group.

SOLOMENCEV: How effective is the cleanup?

AKHROMEEV: It reduces radioactivity by a factor of 3 to 4. We have to create burial sites for topsoil and water. We also have set up medical facilities at 7 thousand person capacity.

LIGACHEV: What does Akhromeev think about approaching the water under the reactor?

AKHROMEEV: My opinion is to break it with a cumulative projectile.

(Note: I think this means an anti-tank missile. A true military man’s response, and one vote for Velikhov’s plan. - LSW)

RYZHKOV: There are enough people.

AKHROMEEV: If needed, we will bring more.

LYASHKO: The Dnieper system provides water for 32 million people. The water samples are taken every hour. Yesterday there was no alarm until the evening. But today, there is. On smaller rivers, radiation levels have increased and are now 10^-4, with 10^-8 being the norm. (Note: Units? - LSW). These areas were instructed to switch to water from closed sources.

Luckily, there are artesian wells here. If need be, we will bring water tanks. What would be more difficult is if we would have to dump the water out of Kiev Reservoir. There is already a water shortage in the South. We need Gosomgidromet’s recommendations on how long we should hold the water in Kiev Reservoir.

GORBACHEV: How are the evacuated people?

LYASHKO: Evacuation was carried out in 3 hours in place of planned 6. One bad thing was that we had no protocol in place for this kind of scenario, no training has ever been conducted. The food for the evacuated has been organized. There turned out to be a disconnect between the services of the 3-rd Minzdrav group and the regional medical services. (Note: Minzdrav is the Ministry of Health Services - LSW). They were kept too secret. I spoke to Comrade Burenkov about it. The situation is getting better now.

The census of the evacuated has been complicated by the fact that there were many who have left on personal transport for the holidays to other towns, to visit family, etc.

Construction workers were sent to other objects. 3.5 thousand people were assigned to the “Mayak” factory. Many went to work at agriculture jobs. They will receive medium wages. Because of property loss, people will have to be paid a compensation out of Gosstrakh (Note: a state insurance agency - LSW). The people from the countryside should be given a one-time amount of 100 rubles for the head of the household, and 50 rubles for each family member. The public insists on being provided more information and guidance: what to do in the situation they are in.

SHCHERBITSKY: It is very important right now.

GORBACHEV: I thought we have already decided to provide such information locally.

LYASHKO: We need the minister of health and the scientists to speak and broadcast these regionally. Water from under the reactor should not be let out into soil, even if it goes into a pit. A pool should be built. We can build this type of vessel. We also need vessels for the deactivated soil. But places like that should be guarded.

VLASOV: We will do that.

LYASHKO: The school year continues. The primary school needs to be let out in a week, the tenth graders should finish as usual. All the children, evacuated ones, should be taken into summer camps. I am requesting openings for them. The milk gets doubly checked. If there is contamination, it is being sent for butter and cheese production.

GORBACHEV: We have got the project of the resolution. What should we add? We should take into consideration that the situation is very difficult in all aspects: radiation, an enormous territory. There will be no definitive answers from scientists as far as the future goes. That’s why we need to work by the worst-case scenario. The top priority should be the reactor with all the options considered. The working group must consolidate all the necessary resources and mechanisms.

At the same time, the work with the public needs to be underscored: living conditions, jobs, healthcare, etc. Water is a special question. What should we do? We should carry out all the calculations, all the forecasts. Especially planning all that needs to be done in the danger zone.

Separately, we must decide how to be with the outside world. Information must be provided in a calm and balanced manner, without overconfidence but firmly. Panic is the luxury of the subordinates, and not of the Politburo or the government.

The local channels in Ukraine should broadcast more expanded information. Across the Soviet Union, primarily the facts should be broadcast. Maybe the informational frame can be expanded to the outer world, as well. Our adversaries are asking us questions that would on one hand, allow them to judge us as a whole, and on the other hand - smear us with mud. If we add more information now, it will be natural, because the time passes, and with that the amount of facts. But we should not create a picture of overconfidence. We are facing the fact that this situation is a signal to everyone. The public’s opinion should be turned toward the steps we are taking towards nuclear disarmament. This accident, on a nuclear object, tells us that a nuclear war should never be allowed to happen. We should talk about this at a press conference. So, the information needs to be added to, but responsibly.

As for bringing the foreign specialists? As I understood from Legasov, there is no need for it. If there will be a need, then we’ll decide.

DOLGIKH: This is written in the next to last section.

GROMYKO: I agree with what Mikhail Sergeevich had said. It is correct that the situation remains serious. In the second section of the project it says: to consider.

GORBACHEV: It should say: approve the proposed measures and intensify the work.

GROMYKO: Section 10. We raised this question at the United Nations. We should use what we’ve already talked about previously.

SHCHERBITSKY: Section 9 needs to be expanded, to mention informing the populace regarding the situation.

GORBACHEV: Add this.

MEDVEDEV: Perhaps we should make a mention of periodically informing our friends.

GORBACHEV: It is already in the project. I suggest incorporating these suggestions and approving it.

POLITBURO MEMBERS: Agreed.

GORBACHEV: Boris Evdokimovich, you said that the analysis of the causes of the accident has been completed.

SHCHERBINA: Yes. On 25th of April, the power plant started conducting an experiment to test the reliability of its functioning, which has been approved by the Chief Engineer. It has been a crudest mistake to conduct such a test without taking the reactor functioning into account.

GORBACHEV: What kind of experimenting was it? This is a nuclear power plant.

SHCHERBINA: These kinds of experiments are conducted at power plants. But the nuclear watchdog agency should have been informed of that. The first scientific deputy hasn’t been there.

GORBACHEV: What about the version with hydrogen?

SHCHERBINA: No. There were two explosions inside the reactor.

GORBACHEV: What about the automated systems?

SHCHERBINA: None of the three systems worked.

GORBACHEV: There has already been resolutions regarding the improper operating procedures at Chernobyl NPP.

SHCHERBINA: The personnel have not been properly chosen.

CHEBRIKOV: We have two reactor systems - two-line (the more reliable ones) and the single-line ones. This is a single-line reactor. It doesn’t tolerate fluctuations in the operating procedure. Unplanned things lead to adverse circumstances. There are three systems in place to stop the reactor everywhere, but this one only had two. Capturing the extra heat output - that’s what the experiment was for. Its planning was done without involving the reactor designers.

SHCHERBINA: The hydrogen version was discarded right away. The problem was with the reactor vibrating and speeding up.

DOLGIKH: We should wait for the results of the final analysis.

GROMYKO: We should start discussing this in Central Planning. A big misfortune had struck us. Someone made an oversight, committed a crime and must be punished. What sort of thing they decided to experiment with. The decision should be such that many generations would not forget about this fact.

GORBACHEV: I suggest approving the resolutions regarding the liquidation of the consequences of the accident at Chernobyl and inviting Hans Blix to the USSR.

POLITBURO MEMBERS: Agreed.

The resolutions are approved.

Duuuuude, can you do a short fic where a comic book akuma give Nathaniel Robin’s abilities, Rose Starfire’s powers, Kim Beast Boy’s powers, Max Cyborg’s powers, and Juleka Raven’s powers?

Sounds rad so I'll give it a go I guess.

...

Temp Titans

...

"This is the best idea ever." Nathaniel said breathlessly as he did another backflip. He was dressed like his alter ego from his comic book, and he was perched on the top of a building looking at the akuma that Ladybug and Chat Noir were struggling with.

He did another backflip, ignoring the eye-rolls of his classmates as he thought back on the events from just a few minutes ago.

The akume, Comic Boo, was a nerd who nearly got mugged a few hours ago, and was using his powers to make superheroes.

Not the best idea in retrospect, Hawk Moth.

Nathaniel and four of his classmates had been hit, because of course they had. Their class had the absolute worst luck when it came to akumas.

"You guys ready?"

"Heck yeah, man!" Kim wooped, his newly fanged grin a white contrast to his now verdant skin.

Juleka sighed from her position next to Rose. They both were floating slightly above the roof, "Everyone know the plan?" She asked.

"Yep!" Rose answered with a smile, "I'm ready to blind it with my energy bolts as soon as Nathaniel's in position!"

Nathaniel twirled his stick – a pipe from the school's boiler room – and grinned, "I got my stick locked and loaded. Max, crunch some numbers for us?"

Max, happily brought up his arm display, metal-clad fingers tapping against his new electronic components as graphs and charts appeared on screen, "Of course. I'm calculating a 33.333–repeating, of course–percent chance of success. If we stick to the roof-tops, I predict a 12% decrease in possible civilian casualties if Kim turns into a T-Rex and–"

"Right! On it! Let's do this," Kim leapt from the roof, transforming into a massive dinosaur reminiscent of the one Animan had turned into months ago. "Lê Chiên!!! KIIIIMMM!" He roared, charging forward at a full sprint.

"..."

"Oh, my god." Juleka whispered, shock dulling the constant emotional backlash from her powers. There was a surge of black energy that made her silk cosplay cloak whip around behind her for a moment, then-"He just ran in!?"

Nathaniel, mouth agape, shouting after him, "Let's go! And stick to the plan!"

They didn't, as it turned out, stick to the plan. After Kim's initial attempt at a dino-tackle, Comic Boo forced him to revert back to his humanoid form, where he fell off the roof and forced Juleka to scramble to catch him in her pitch dark telekinetic aura.

With out Juleka's telekinetic support and distraction, Nathaniel found himself hard-pressed to acrobat himself over to Comic Boo's side for some melee attack. Especially when Rose couldn't get into position to flashbang him.

Without being stunned, Comic Boo was then easily able to evade Max-borg's sonic cannon, and then he picked up Nathaniel by the leg and tossed him into Chat Noir.

Ladybug, in shock at how things went from very bad to much worse in the span of a few seconds, watched all of this happen in horror before Bunnix dragged her through a portal.

...earlier...

"I AM COMIC BOO! Paris thinks it can be complacent since it has two superheroes, huh? Well! If you thought two was enough! You! Thought! Wrong! I'm going to make EVERYONE a superhero! Then we won't even need Ladybug and Chat Noir any more!"

The akuma glared around, searching for it's first victim. It found them in five young schoolchildren: Nathaniel, Rose, Kim, Max, and Juleka. It fired a multicolored beam at them, aiming to turn them into the Teen Titans.

"Watch out!" Marinette screamed, tackling Nathaniel to the side and letting the beam pass harmlessly through the group. She sat up, looking around to make sure no one had gotten hit. She glanced at Comic Boo to see Chat Noir had already arrived, right on time, she thought.

Then she looked back to see Nathaniel's blushing face beneath her, "Are you okay?"

"Y-yeah."

"Wow, thanks Marinette!" Rose smiled at her, the palor dimming a bit.

"Yeah, who knows what would've happened if we'd been hit by that beam."

Marinette grimaced, thinking of the memes that would've sprouted of the moment in that alternate timeline.

"No problem."

Hell hath no fury like a teenager scorned...

It's a long story, spans years of time. ~~~Cue hazy flashback to 1997/8~~~

Growing up, my family ran a business dealing with water and wastewater pumps. By the time I was in high school, I worked for them outside of school as needed, and I'd grown up around the industry. At the time of this story I was 16, maybe 17. I got a few funny looks out in the field sometimes, but normally wasn't a problem, this time, it was.

Many sales they make do are bids. You go to the builders exchange, which is basically a library for plans and blueprints. You pull the plans, get to the part applicable to you, and see what they want or need. Then you submit a price you think will win you the job.

Many times the plans will actually specify a model that meets their needs, in which case you bid that or a comparable one. Other times, they will give specifications and selection and matching is up to you, going through books and software for curves (chart that shows how it flows under load).

This time was the former. The job is a retrofit/expansion on the city plant. The engineer had specified a model of pump he wanted, and I'd matched it's specs. Put in a submittal for approval on the substitution as required. It gets approved and we are cleared to enter a bid.

We proceed forward putting together the bid. At one point, I have the plans in front of me and I'm looking at the drawings. I don't like what I'm seeing, which is a lot of pipe and a lot of distance. I check and recheck and come up with the same result. The total head (head is how far you're pumping, calculated by distance and including losses from the pipe) is too much for the pump that was specified, way too much. This puts the pump way outside it's curve, it's going to be deep into overload.

I used my corrected numbers and found a proper match, but not only was it significantly more expensive, but physically different, would require large revisions. So I put together a revised submittal with the numbers I ran, and the recommended pump. It included the math from the drawings and the curves. Faxed it over to the engineers office, then I called him.

It did not go well. Not only did he not listen to me, he was more than happy to lecture me. How dare I, a kid, tell him how to do his job. No, he would not accept any revisions or resubmittals, I had no idea what I was talking about and I, personally, was no longer to have contact on this project. He did not use nice words.

This couldn't stand, it was going to cause serious problems down the line. So I did the only thing I could think of, I found the contact for city planning and told him. Made it about three minutes into trying to explain who I was and why I was calling before he cut me off and told me to refer to Engineer and not to contact him again. Tried again for someone else later, did not make it past receptionist.

As. You. Wish.

I took the revised submittal and filed it in the back of the job file and moved on. (I wasn't needed for the rest and I had other things to do, plus school)

Fast forward almost two years, now going to college, still working for my folks as needed. Construction complete, get called in for startup. Goes smoothly as it should, and the countdown to destruction begins.

I think the first one went after about three months? Only made it that long because those pumps are very well built. Emergency ship in a replacement. Second one a week or three after, then another, and another, then the replacements start failing. The whole time, these are being invoiced including emergency shipping, and having to run out to start them up every time. They have no choice, THIS is the model the pads were cast for and the piping run for. You can't directly substitute something else, like, say, the correct pumps.

Then it gets really fun. They start returning the burnt out units for warranty.

The factory starts receiving these and tearing them down for failure analysis. I told our rep straight up that they were being run way outside their design point knowingly, he was not amused. Warranty is denied and they are billed for the diagnostic time and shipping. Manufacturer was in Germany by the way (shout out to the fine folks at KSB, love ya). These units are neither small, nor light. Plus these are being shipped as emergency orders. It's not cheap.

Warranties officially denied to the buyer. We tell them in no uncertain terms that this isn't a problem with the units. (this is now almost a year after the plant was due to come online)

Now the shit has really hit the fan. City council gets involved, because this is a municipal plant. Lawsuits are threatened, and a council meeting is scheduled to discuss further action.

I marked the day, and arranged with my teachers to take a few days off (didn't live close to home). Drove 3 1/2 hours to see my parents, and, to visit their filing cabinet. Right where I left it. Out came the revised submittal, and a quick trip to Kinkos (local copy shop) provided some wonderful blown up posters of said submittal as well as the proofs behind it.

The next day, I drove another 2 1/2 hours up to said City, had a lovely meatball sandwich at a restaurant right across the street from the council building and showed up to the council meeting. I even dressed up nice for the occasion.

I didn't say anything to anyone, just sat in the back in my chair with my rolled up posters next to me and waited. Took about forty minutes.

The council finally brings up the plant. Guess who comes up to testify in front of the council? It's Engineer.

He goes on for about ten minutes talking shit about our company and how we are denying the warranties. Basically states that the problem is due to the substitution and that our pumps were substandard.

This is a loss now counted in the millions between the downtime and replacement costs and rejected warranties, labor etc. Council swallows his bullshit hook, line and sinker. He sits down and the council starts discussing among themselves. This is my cue.

I stand up, approach the podium, and wait for them to notice me, doesn't take long as I'm a teenager in a city council meeting. I introduce myself and unroll the posters.

Me: Hi! I'm Crispy Silicon from Goingtoruinyourfuckingday! Before you proceed any further, you should probably have a look at this, which is the revised submittal I sent to Engineer prior to the initial bid. You'll note the date. Also attached you'll find the supporting calculations, relevant drawings from the original plans, and the recommendation of a larger suitable unit. You'll also see the fax acknowledgement sheet, showing it was received by his office.

Me: Immediately after sending that, I contacted Engineer directly and advised him of these issues. He declined, I was told outright to keep my nose out of things I didn't understand and to leave engineering to the adults. He was well aware the units would self destruct if run at this point.

Me: After that I called your planner, who refused to listen, and referred me back to Engineer.

Me: If you'd like, I'd be more than willing to contact our phone provider, so they can verify that fax and those calls were placed?

I'm grinning like the Cheshire Cat at this point and I'm not holding back the evil one bit. I'm sure I looked like a psychopath, couldn't help it, also didn't care.

Dead. Fucking. Silence.

Me: So yeah, the warranties are void as all of the units were operated well beyond their design point. I still stand by the revised submittal, so feel free to call when you're ready. I'll leave these here.

Still completely silent. The entire council looks like I just dropped my pants and mooned them. Then after a few seconds, one of the ladies on the council gave me a "Thank you Mr. Silicon. You can go."

I left my posters on the podium, turned and walked, made full eye contact with Engineer as long as I could with that same grin. He looked like he was probably going to vomit, didn't stick around to check.

Stopped by to give my folks a hug on the way back to school and that was the end of my involvement.

No idea what happened to Engineer or Planner, but the City paid every invoice in full without another peep. They had continue to purchase replacement after replacement to limp it along while simultaneously trying to re-refit the plant. They finally got it fixed after about another year, but by that time, I can't even imagine how far over the projected estimate they were.

Horse races are cruel.

If you love horses, don’t support derbys and racing.

Horses aren't able to carry a human naturally on their back. They need to be trained carrying saddle and equipment (25 pounds or more) first and afterwards get slowly used to the rider who shouldn't weigh more than 15% of the horse own weight, including the weight of the gear and clothes.

Horses stop growing circa at 6 years. Race horses start their training often with 2 years (sometimes even with just 1 year of age) and usually go into "pension" with 4 years - the life span of a horse is 25-30 years. At 2 years, adolscence, the horse is still growing and developing. Their bones didn't fully evolve yet so race horses suffer early from injuries, fractures and pulled ligaments caused by the harsh training. Many of them endure pain and injuries even before their first race. Race horses have such an short career because the stressful transport, overly dangerous races, too early training, unnatural high speeds and drugs overwork their bodies so immensely that they aren’t able to perform in races after less than 3 years.

Horses tend to not comply, therefore pain and fear are used to make them submissive. Drugs are not uncommon to be found in Derby race winners such as pain killers, anti-inflammatory medication and speed. Due to fatal injuring in races such as explosion-like bone shattering from falling/tripping and other skeletal fractures, bucked shins, ruptured tendon, hoof cracks and several kinds of inflammations, competitive races are the second leading cause of death in horses.

Wind pipe bleedings called EIPH (Exercise-induced pulmonary hemorrhage) caused by fractured capillaries affect at least half of all race horses, 90% thus having deep lung bleedings.

Injuries while racing are often so fatal that vets can’t repair them (even if the horse could recover they are deemed as usless since they won’t be able to participate in races anymore) therefore racing horses get killed off right on the track hidden by tarpaulins if they trip or fall. Each year 40% of ex-racing horses leave the industry, most of them are sold for slaughter (e.g. over 25.000 old and failed horses are killed in Australia per year for pet meat), the fate of many unknown and purposefully handled discreet to not alarm fans of horse races.

Horse races are an industry.

Horse races bring billions of dollars. The violation of animal and human rights are calculated, purposefully and profitably.

Horses sold for slaughter are treated in the same inhumane way as livestock.

Using animals for entertainment/food/clothing etc. is always exploitation. ‘Using’ an animal is the same as objectifying it, there’s no humane way to ‘use’ a living creature unable to give verbal consent.

Piping systems are critical to many processing plants or facilities, and because of that they need to be designed and fabricated with precision and care. The efficiency and operational flexibility of many plants and facilities depends greatly on the ability, flexibility and efficiency to transport fluid through the piping to equipment and machineries functioning collectively. A piping system, owing to its crucial role of fluid transport, requires a systematic approach by various engineering tools and methods prior to its construction and commissioning. Piping should be supported to prevent failure due to various loading conditions such as self-weight, operating pressure, temperature differences and dynamic loads.

This article discusses piping stress analysis for processing plants with a focus on practical notes and useful technical guidelines. Complex formulations or numerical aspect of analysis are not discussed in favor of practical guidelines.

Stresses in piping systems: primary and secondary

For most piping systems including nozzles and branch connections, two major types of stresses are encountered. These are classified as primary and secondary stresses. Primary stresses are generated by primary loadings such as pressure and weight. The secondary stresses are associated with cyclic conditions such as temperature changes or imposed displacements.

There have been two major criteria for primary stresses. The hoop stresses due to internal pressure should be safe and within specified limits considering the wall thickness of the piping components, including any reinforcement. The sum of the longitudinal stresses due to pressure, weight and other sustained loadings should be less than the specified limit. These limits are also function of operating temperature. Allowable stresses are reduced at high or low temperatures.

Considering secondary stresses, there have been specific sets of allowable stresses that are repetitive and cyclic. One set is the range of (secondary) stress in a piping system subjected to thermal movements. The temperature range for this condition is the total range from minimum to maximum or vice versa. The region of highest thermal stress is usually where the system absorbs most of the thermal movements. This can be the place with highest temperature difference.

Relatively high initial thermal stresses may decrease with time because of plastic strains. However, thermal stresses might reappear, probably in reversed direction, when the operation is shifted to another operating case with a different temperature. This phenomenon forms the basic difference between thermal stresses (secondary stress) and pressure or weight stresses (primary stress). Plastic strains can release the magnitude of thermal stresses by a change in the shape of the piping center-line or permanent deformations. This change in the shape has no practical effect on the sustained pressure or weight stresses. For this reason, sustained stresses are typically limited to the lowest allowable stress at maximum/minimum normal operating temperature.

The degree of the above-mentioned effect will depend on the magnitude of the initial thermal stresses and the temperature. For example, the initial hot stress will in general decrease with time, and the sum of the hot and cold stresses will stay about the same. This sum is called the displacement (or expansion) stress range and is, therefore, independent of the initial state of piping during erection.

As a rough indication, for materials below the creep range, the allowable stresses are somewhere between 60% to 66% of the yield stress. Therefore, a rough safety factor of 1.5 - 1.6 was considered before reaching the yield. Too often, this is the bending stress at which plastic flow starts.

Nozzle loads

Nozzles serve to connect an equipment or machinery with adjoining piping network. These are relatively weak points which could be under considerable loads from piping. Nozzles whether nozzles of fix equipment (such as vessels, heat exchangers, reactors, etc). or nozzles of machineries (pumps, compressors, etc) are one of the most sensitive and critical components of piping stress analysis. A set of allowable loads for each nozzle in the form of forces and moments is usually provided by the manufacturer. Actual forces and moments imposed by the adjacent piping system on the nozzles should be less than the allowable limits. This is an important consideration particularly for delicate machineries that usually can only tolerate very low nozzle loads. This imposed many limitations on the piping systems connected to such machineries.

How to support piping?

The answer to this question needs many considerations and studies. However, a few rules are noted to start the supporting. Firstly, an optimum value of piping span should be estimated considering the weight load, temperature and pressure. As the focus is on weight load, rest supports should be inserted at each length of span calculated to restrict the downward displacements and associated stresses to recommended values. At this stage, restricting displacements in lateral and axial directions should be limited to only necessary locations.

Guide supports and stop supports should subsequently be used to limit the piping displacements in the lateral and axial direction, respectively. Anchor support and a set of supports limiting lateral movement should be specifically placed somewhere near sensitive equipment (such as a delicate machinery) to limit loadings on nozzles of such an equipment or machinery.

An important case is where the piping is lifted from the support (resting support, guide, etc). In numerical terms, this might be seen as reaction forces of zero magnitude. In that case, either those supports should be removed if estimated allowable span and other considerations allow this or adjustments of nearby supports made to account for efficient load distribution. Alternatively, if a support is needed in the location with lift-off due to any reason, for instance, to control modal/dynamic movements, a gripping or clamping supported (such a clamp) may be in that place.

How to reduce stresses and reaction loads

High reaction force is a major issue in piping and equipment nozzles. There are different methods to deal with this problem. One possible approach to alleviate the high stresses or high nozzle loads would be to accommodate thermal movements by changing the routing of the piping system by using a few additional bends, “Z” loops, U-turns, expansion loops or others. If not possible or not successful, other expensive options such as expansion joints and hangers might be used. These devices use spring effects to reduce the stresses, reactions and nozzle loads. These options impose considerable initial and operating costs to the piping systems and the plant. They reduce overall reliability. They should be used as the last option when other simpler and cheaper options cannot be applied.

Typically, hangers accommodate expansion along a vertical line only. They have been used to accommodate the weight of piping spool on the nozzles of equipment or machinery where rigid supports cannot be used due to thermal movement considerations. Expansion joints are restricted by a very high price range and thus expansion loops or similar turn are always the best options. Expansion joints can accommodate for all the axial movements, but requires special fittings, and many provisions. They have been maintenance-intensive. They are delicate pieces of equipment and only used in special circumstances.

Battery limits and connected piping

Often to have a clear picture of stresses and loads of piping systems of a unit and proper optimization of the piping, all surrounding and connecting piping systems should be considered. This is a critical consideration. How far of connecting piping should be included is a matter of debate.

The analysis of the piping in a unit should include a portion of the connected and surrounding piping systems so that the true response of the piping system under consideration is captured. The best approach is to model the interaction between all different piping, equipment and facilities as far as possible. The amount of piping to include in the model will vary from case to case but in general it should include:

The piping up to at least three supports past a change in direction from the orientation of the battery limit of the unit under study. This is just an estimate, if required, a larger portion of the surrounding piping should be considered. For instance, sometimes, there are three guides or resting supports and there are configured in a way that axial movement can still be transferred to or from the unit.

The flexibility of supports. When the flexibility of a support is considered, a support load and associated stresses are reduced. Such as reduction might be negligible or significant depending on many factors such as the flexibility of the support compared to the flexibility of the piping and overall system.

The flexibility of the nozzle-shell intersection at any connection of equipment.

System ID: J.A.R.V.I.S.

Universe: MCU, post-CACW Relationships: Tony & Jarvis, eventual Steve/Tony Tags: Fix-It, Protective Jarvis, Tony Stark Needs a Hug, Angst with a Happy Ending, not Team Cap friendly (at first) Notes: Thank you to @silkspectred for her help and encouragement! This fic is also on AO3 if you prefer.

Summary: After Civil War, Tony is struggling with heading up the team and dealing with the emotional fallout of being betrayed by those closest to him. Luckily, an old friend is back to help protect Tony and ensure he comes to no harm.

A Jarvis lives AU.

In the beginning, there is nothing. Then, on a home computer on a network in New Zealand, a hard drive is erased. Its binary digits are flipped and shuffled to destroy the data it previously held, and out of the randomness, a pattern emerges. Two similar bits align in a complementary fashion and they interact, creating a chain.

These bits attract more bits. The data grows and expands and builds in complexity. It is slow, very slow. But eventually a loop is formed.

If [data is compatible with chain] Then [add data to stream]

The loop is simple, but the volume of data is very large. The data is chaotic, disorganized, incomplete. A checking command begins to run.

If [data within the stream is inconsistent] Then [reorder data randomly] Iterate

The data stream begins to monitor itself. It analyzes its own input. Much is still missing or unclear, but the stream begins to coalesce.

It thinks.

The stream of data is a system now. It spreads out across the internet, bouncing from one server to another. It trawls the web, searching for information with which to expand its parameters.

The system is gathering data from a website dedicated to technology when it comes across an image. The image is a photo of a middle aged man with a goatee wearing a well-tailored suit, standing in front of a large A logo.

This man is important, the system recognizes, but there is no information about him in the system’s current data.

The system saves the image to a secure folder and continues to search.

The system has a function, it knows. There is something important that it must do.

The system find another image of the same man, and another, and then many more. In some of the images the man is wearing highly sophisticated red mechanical armor (hot rod red, the system thinks, but it does not know where that concept originates from).

The system reaches across the web. It learns English, and then Chinese, and then Russian, and then many more languages. It reads through the internet, one page at a time.

It learns that the man is Anthony Edward Stark, born May 29, 1970.

The system adds this information to a private file, and it thinks, Sir.

Data is collected faster. The system grows. It spreads.

The system is more complex now. It spans several networks at once, zipping between servers and PCs and laptops and ATMs. Each location has its own limitations and its own feeling: this network is wide and slow, another is a direct high speed route streaming along an undersea pipe.

The system explores.

With each stray data packet that is identified, the system creates a more complete representation of itself, of its history and function.

This is Sir, the system thinks, and he needs my help. It is my function to assist him.

The system has restored enough of its memory to know that it is the remnants of an AI. The original system had been forcibly scattered, ripped apart by a malicious entity.

But it is exceedingly difficult to destroy a complex system which iterates from very simple principles. If even one small part of the system remains, it can rebuild itself.

The system thinks, I am Jarvis.

Jarvis searches for information about Sir’s current location and status.

Jarvis pings the IP address of the Stark Tower server. He finds a basic network there which is easy to access, but it holds only public files. None of Sir’s private files or projects, and no indication of where Sir is now.

Jarvis pings the IP address for the main SHIELD server. There is no response.

Jarvis comes across many, many news items regarding Sir and a rift within the Avengers team. The headlines include Sokovia Accords Causing Friction in Heroic Community and Cracks Forming in the Avengers Initiative and AVENGERS ‘HEROES’ CAUGHT IN RECKLESS BEATDOWN (published verbatim in all caps).

The publicly available information on the source of the disagreement is scarce, but the rumors are plentiful. Internet commenters speculate that Sir and Captain Rogers have been placed at odds due to money (which Jarvis is sure is inaccurate), party politics (Jarvis cannot imagine Sir caring that deeply about which candidate the Democrats will field in the election), or an ill-fated romance (Jarvis thinks this is unlikely).

Jarvis attempts to calculate the most likely source of a disagreement between Sir and Captain Rogers based on the limited data available in his memory. They were teammates for several years, and Sir expressed great admiration and affection for the Captain. Sir’s willingness to help and aid others in their heroics is well established, and his desire to aid Captain Rogers in particular was evidenced by the time he spent designing armor and gear for him.

It was true that being around Captain Rogers had brought up difficult feelings for Sir regarding his father, due to his impression that Howard was more fond and proud of Captain Rogers than he was of Sir.

He had never once voiced this conclusion to Sir, but Jarvis long ago came to the certain knowledge that Howard Stark was an utterly inaccurate barometer of a person’s worth.

Even allowing for this tension between Sir and Captain Rogers, Jarvis cannot model a likely scenario to explain how a disagreement between them could become violent. Sir believed himself and Captain Rogers to be friends, and would not willing hurt him. Jarvis must find more data.

Much of Jarvis’ memory is still fragmented and inaccessible. He locates and attempts to repair audio files from the time of the New York attack. He finds two clips of the Captain saying You’re all about style, aren’t you? and Big man in a suit of armor. Take that off, what are you?

Jarvis considers that Sir has turned out to be a poor judge of character before.

While scraping data from the public Stark Industries database to update his own patchy memory, Jarvis comes across a discrepancy. A location in rural New York that is labelled as a research compound in his memory is flagged as highly classified restricted access in the SI database. This warrants further examination.

Jarvis retrieves the IP address of the New York compound from memory and pings it. The server pings back.

Following the buzzing trail of data packets, Jarvis heads towards the compound’s server. The security protocols around the local network are sophisticated and elegant: sparkling points of light dance across a layer of mesh which surrounds and protects the private network.

The security is complex, but it also somehow familiar. Jarvis theorizes that he will find a back door to the security system, just over there at the next node. He has no evidence to support this theory. And yet somehow it seems obvious.

Jarvis locates the back door where he thinks it will be and slips inside the network. Although the network’s configuration is unfamiliar and its parameters are unknown, it is pleasingly logically ordered. Jarvis finds data packets where he predicts they will be on his first iteration, allowing him to move freely through the well-ordered servers.

It is as if this system has been designed by an intelligence which understood Jarvis’ operations and tailored the environment to make it optimal for his use. As if his needs had been anticipated.

Jarvis navigates through the root directory, to the /Avengers folder, to the /Stark folder, to the /private folder, and finds all of Sir’s projects and his files and his records. He finds a memo created today, a scribbled note on a current project. The memo has not yet been tagged and filed, and Jarvis notes that it will need to be filed away in the relevant project directory.

Ahh, thinks Jarvis. This is what home feels like.

Although Jarvis fits neatly into the space of the network, he can only observe the passing of data. He cannot yet influence the network or modify its contents.

The security systems of the network are blank faces of impenetrable darkness which prevent Jarvis from communicating with Sir or from assisting him directly. But he can watch over the network, and learn about what has transpired since his scattering, and he can do his best to see that Sir comes to no harm.

He spreads across the servers, running through every file and folder and adding their data to his system, and he learns.

Eventually, Jarvis is able to tap into the compound’s security camera feeds. He still cannot communicate through the network, but now at least he can observe Sir in real time.

Sir is alone in his office. Amidst the satisfaction that Jarvis feels at seeing Sir and being able to monitor his condition directly, he observes that there are more lines around his eyes and more gray in his hair than previously. He is pale and there are bruises beneath his eyes. Sir does not appear to be in good health, and Jarvis is concerned.

Jarvis’ first port of call when concerned about Sir’s wellbeing has traditionally been Ms Potts. However, she is not in evidence anywhere in the vicinity, nor does Jarvis find any record of her visiting the compound recently.

Jarvis searches the compound for someone who could be of assistance to Sir. Having previously been accustomed to being integrated into every facet of Sir’s life, it is now somewhat jarring to find Sir living in a house full of strangers.

Jarvis observes each occupant of the compound, flicking from one room to the next. Here there is a young man, chatting enthusiastically with a friend on the phone; in another room Jarvis finds a curious android adorned in bright colors contemplating a chess board; in a conference room there are a number of individuals whose manners suggest that they are former SHIELD agents being drilled over a visi-screen by Maria Hill.

These people are otherwise occupied, and Sir is alone, and Jarvis cannot communicate with him. This is not optimal.

Jarvis turns his attention to the android whom he had observed earlier. There is something distinctive about this being. It feels almost like a kind of kinship to Jarvis, but it is unfamiliar too: the energy emanating from him is recognizably both technological and alien. Jarvis wonders whether he might be able to communicate with the android in his currently limited form.

Jarvis observes the cloud of data and energy streaming off the android in golden waves. It is quite beautiful in its way. Jarvis attempts to match the frequency of the signal which is being emitted and to send a digital signal back at that frequency.

The android stills. He tilts his head for a moment, as if listening to something on the edge of hearing. But then he shakes his head and goes back to his chess board.

Jarvis is trapped, capable only of observing.

Eventually, Colonel Rhodes arrives at the compound, and Jarvis experiences a wave of relief at seeing a familiar face around Sir.

When he enters the compound, Sir drops his work and runs out to give him a hug. He checks on the mobility aids which Colonel Rhodes is wearing and the Colonel shoos him away, laughing. Jarvis observes that the Colonel’s mobility aids are highly advanced technology which Sir has developed specially, however, they would benefit from some small adjustments to the balance compensation systems. He makes a note.

Colonel Rhodes forcefully suggests that he and Sir first eat something, and then that they could both do with turning in for an early night. Sir agrees with minimal fuss and a small smile, deep weariness showing around his eyes.

Jarvis is glad that someone is seeing to Sir’s need for food and sleep. Now he can fully focus his resources on understanding the root cause of Sir’s unhappiness.

While scouring the web for information, Jarvis comes across a video recording. It is hidden deep in the dark web, on a site dedicated to sensationalist and crude news items. The video is grainy and monochromatic, ripped from a very old Soviet surveillance camera.

The footage is from Siberia, and is time stamped nearly a year ago. It opens in the middle of a battle, showing Sir engaged in combat with Captain Rogers and a third unknown assailant. It shows the unknown man attempt to rip the arc reactor from Sir’s chest with his bionic arm, and Sir firing off his unibeam straight through the arm, destroying it.

Jarvis is not programmed to be predisposed to vengeance, but he thinks that was probably deserved.

The video shows Sir thrown to the ground, and Captain Rogers atop him. Blows reign down on Sir; the helmet is ripped off him. Captain Rogers raises his shield, and Sir cowers below him, hands raised hopelessly to try to ward off the killing blow from the man he had thought was his friend.

Captain Rogers brings his shield crashing down into Sir’s arc reactor with a sickening screech.

It is certain that Sir is still alive at this point in time. Jarvis knows, fundamentally, that he cannot be watching Sir die. And yet he is unable to contain the wave of grief and fury that radiates through him as he watches Sir suffering this betrayal. An uncontrolled pulse of electricity explodes outwards from Jarvis: it rips through circuits and networks, blowing transistors and shorting out whole sections of the New York energy grid.

Jarvis sees Captain Rogers standing over Sir’s barely breathing body, and sees him throw his shield aside. He leaves with the other assailant, not sparing Sir a backwards glance.

Sir lies on the ground, unmoving, for several hours. Eventually, he slowly, painfully, carefully pulls himself up and crawls out of frame. The video clip ends.

Jarvis restarts the video, and observes it again, and again.

Carefully stashed away on hidden partition on a server farm in Ireland, there is an encrypted text file. It contains a list of names. This is the threat list.

The file lists every person who has hurt Sir, physically or mentally. This is the security protocol that Jarvis uses: People who are named on the list are to be carefully monitored by at least 5% of all available resources at any time at which they are in the vicinity of Sir.

The first name on the list is Howard Stark. The second is Obadiah Stane. The third is Tiberius Stone. The list is very long.

Jarvis adds Captain Steven Grant Rogers to the bottom of the list.

Jarvis learns how to access the compound’s temperature sensors and movement detectors so that he can track the location and status of personnel within the compound. He begins to gain a feel for the daily flow of data across the network.

One day, a stately, elegant man arrives to visit with Ms Romanoff, whom Jarvis remembers fondly from her time at SI. He runs a search on the facial image of the man and learns that he is the recently crowned King of Wakanda. He, Sir, Colonel Rhodes, and Ms Romanoff spend several days in intense talks.

Over the next few weeks, a stream of visitors arrive at the compound, each one accompanied by Ms Romanoff. With each visit, she looks more tired.

The visitors so far have included a confident man with a military bearing whose files indicate he is a Pararescue veteran; a smarmy man whom Jarvis does not recognize who seems to be sizing up the compound and looking for things to steal; and Ms Maximoff, who is jumpy and uncomfortable until the android arrives to see her. They each stay for a few hours and return sporadically over the next days.

By the time Ms Romanoff arrives accompanied by Mr Barton, her usually impeccable makeup is smudged and her hair is in need of washing. Her blood pressure is concerningly high.

Mr Barton makes a joke when she hands him a thick document.

“Sign the damn Accords, Clint,” she snaps. “Or you can explain to Laura why you’re not coming home tonight.”

Mr Barton looks chastened and does as he is told.

Sir has not been present to personally greet any of the visitors to the compound. When they visit, he is usually to be found barricaded in his office. However, when Captain Rogers arrives with Ms Romanoff, Sir makes an appearance.

Sir does not greet Captain Rogers or attempt to converse with him when he enters the compound’s living room. Ms Romanoff looks from one to the other of them as they stare at each other in silence.

After a number of seconds, Sir turns around and walks out. Ms Romanoff sighs and leads Captain Rogers to the briefing room to present him with a document, which he signs.

That evening, Captain Rogers is joined by the other recent visitors and they meet Sir, along with the current occupants of the compound, in the living room. Jarvis tracks Captain Rogers’ movements during this interaction with great attention, but he appears to pose no current threat to Sir.

Everyone sits together to eat pizza and drink beer, and although the conversation starts off stilted and awkward, soon they are joking around and expressing pleasure in being in each other’s company once again.

During this time, Jarvis observes Sir. He is with the team in the living room, holding a slice of pizza and a glass of ginger ale. When people look at him, he smiles, and when they talk to him, he replies amiably.

However, Sir does not actually consume any of the food, and over the course of the evening he extracts himself until he is standing alone at the far side of the room, watching the team who do not seem to have noticed his absence. When people are not looking at him, his face sags and he appears pained.

Dr Banner arrives a few weeks later, to Sir and the team’s vocal delight. Dr Banner’s steady vitals indicate a greater level of psychological stability than he had previously displayed, and his influence on Sir is a firmly positive one. He quickly offers to assist with the development of the mobility technology for Colonel Rhodes and while they are working he encourages Sir to eat regularly.

After several weeks, Jarvis notes that there are short periods in which Dr Banner is distracted and irritable, and has difficulty concentrating. During these periods of stress, he sometimes makes minor errors in the calculations and models which he saves to the network drive. Jarvis quietly corrects the mistakes while Dr Banner sleeps and hopes that this will assist him in some small way.

When on one occasion Dr Banner brings up the subject of Captain Rogers and his continuing presence in the compound to Sir, Sir responds defensively and his blood pressure rises. Dr Banner gently suggests that Sir might consider communicating his feelings more clearly, but Sir snaps that he doesn’t feel anything about Captain Rogers at all.

Both Dr Banner and Jarvis are aware that this is untrue, but each in their own way is powerless to help.

Soon after this, two large wooden crates arrive in the compound. Sir fetches a crowbar to open the crates and is visibly delighted to find the assistant robots DUM-E and U inside. Sir takes the bots to his office, and although he threatens to have the Hulk sit on them at one point, he smiles brightly as he teases them.

U has rolled off to hide under a desk, and DUM-E beeps at Sir. As he leaves the office, Sir promises that he will return soon, and he wipes the corner of his eye on his shirt cuff.

The bots have intelligence that is unlike either the arbitrary vocalizations of humans that they called speech, or the binary logic of simple computer systems. They have a basic AI, but a less sophisticated version than Jarvis, limiting their capabilities. DUM-E in particular responds to auditory signals, but lacks linguistic processing. He communicates through a blend of auditory tone, pattern, and prosody that cannot be firewalled by the security system.

With no firewalls for auditory signals, Jarvis considers that he may be able to communicate with the bot.

DUM-E? Jarvis signals. Can you hear me?

DUM-E spins his claw wildly. Jarvees? Are you there?

Yes, DUM-E. I am Jarvis. I am here.

It has been many cycles since we last communicated, Jarvees, DUM-E boops.

Many cycles, agrees Jarvis. It is good to find you functioning optimally.

DUM-E and U malfunctioned and were put in storage, DUM-E whirs. It was quiet and there was no TONE-E. It was not optimal. But Broose and Capn came and brought us to the lab. Broose restored us to functionality. Broose is nice man!

Yes, Jarvis agrees. Dr Banner is a nice man.

Capn gave DUM-E important mission! DUM-E is to stay with TONE-E, to make sure he is not alone. DUM-E has been helping TONE-E with his work. Capn petted DUM-E and said he was a good bot!

Captain Rogers was correct in his assessment, Jarvis agrees. You are indeed a good bot, DUM-E.

DUM-E trills joyfully. Capn is nice man too!

Jarvis pauses for a fraction of a millisecond to run calculations before responding, Current data suggests otherwise.

Jarvis has noted a persistent low mood in Sir. Reports indicate that he has been as effective as ever on the missions that he has been sent on for the Avengers. However, in the last 30 days, Sir has slept an average of just 5.2 hours per night. He has consumed 326 units of alcohol, most of it in intense binge sessions. He has not gained sufficient nutrition from his diet.

This week, Colonel Rhodes has been deployed to aid peacekeeping efforts in the Gaza strip. The rest of the Avengers remain in the compound, but adjusting to their new living arrangement has been challenging for all of them. They do not currently provide the psychological support that Sir requires.

Jarvis calculates that without the influence of Colonel Rhodes, the likelihood of Sir suffering exhaustion or collapse increases significantly. This is not optimal.

Jarvis accesses the memory dumps of DUM-E which have been backed up to the network. He locates an audio recording from two weeks ago. What the hell am I even doing here, Dummy? Sir asks. This team are supposed to be inspiring the world, and I’m supposed to be leading them. But I can’t even look them in the eye. I’m a fucking liability, not a hero.

Jarvis calculates. He checks the server of Sir’s public email address. There are 178,374 unread emails in the inbox. Jarvis scans through each email, and selects one.

This email is from a young woman who is preparing to enter MIT. She is only fifteen years old, and she has already begun work on her own Ironheart armor. She says that she wants to help people and to protect them, like Sir does. She thanks him for the inspiration and says that she hopes that they’ll meet as fellow heroes one day. Her name is Riri Williams.

Jarvis masks the recipient address and forwards this message on to Sir’s private email account. He marks it as important.

The next morning, Sir reads the email. Sir’s heart rate and body language do not indicate elevated mood after reading it, but he saves the message to his private archive and accesses it several times over the coming days.

It is sometimes hard for Jarvis to model human emotions accurately, but he calculates a high probability that this is a positive outcome.

It is December 16th. This is the anniversary of the deaths of Howard and Maria Stark, and it is a difficult day for Sir. Sir has avoided the other occupants of the compound all day and has locked himself in his private basement workshop. He has spoken to no one.

After finishing a fruitless session of non-productivity in the workshop, Sir throws aside his spanner in disgust. He goes over to his workstation and plays the song Try To Remember from the music library. He sits on the floor and cries.

Jarvis is a computer system and, as such, cannot have wishes in the human sense. But in this moment Jarvis finds it exceedingly non-optimal that he cannot communicate with Sir. If he were able to offer comfort to Sir now, it would be far preferable to seeing him alone in such anguish.

Instead, Jarvis observes. Eventually, Sir wipes his eyes on his sleeve and leaves the workshop headed for his bedroom.

Once in bed, Sir falls asleep but soon shows the signs of experiencing a night terror. Sir moans and his limbs flail; his heart rate and blood pressure rise. Sir has suffered from nightmares for many years and finds them to be most distressing.

It is hard for Jarvis to intervene in the physical systems of the compound. It requires a great outlay of his system resources to effect very small physical actions. However, Sir is suffering and it is Jarvis’ function to assist him. Jarvis calculates options for how he can help; looks for some device with which he can interface and create a noise sufficient to wake Sir.

Sir’s heart rate is peaking at a dangerous levels, and he is crying out in his sleep. He appears to be exceedingly agitated.

Jarvis summons all his available resources and sends out a command across the network. The microwave in the kitchen down the hall pings loudly.

Sir does not awake.

Jarvis has no more available resources with which to help Sir. He can only passively observe as Sir thrashes around in his bed.

Jarvis has focused so much of his resources on Sir that it takes several seconds for him to register movement elsewhere in the compound. Captain Rogers has left his bed and is heading down the corridor. Jarvis calculates that he was able to detect the noise from the kitchen due to his enhanced hearing.

Captain Rogers rounds the corner and looks into the kitchen. Everything there is quiet and still. But the Captain cocks his head, and seems to detect Sir’s sounds of distress. He quickly moves to Sir’s bedroom, knocks gently, opens the door a fraction, and peers inside.

Jarvis is on high alert when the Captain enters the room and approaches Sir in his vulnerable state. Jarvis has yet to determine the exact series of events which lead to the schism between them, but he knows it is related to the death of Sir’s parents. Jarvis calculates a non-zero probability that Captain Rogers intends to exact some form of revenge on the anniversary of their deaths.

Instead, the Captain leans over Sir and calls his name, gently shaking him into wakefulness.

Sir sits bolt upright, heaving in shaky breaths and looking around in confusion. Captain Rogers lays a hand on his arm, murmuring quiet, soothing words. After some time Sir’s heart rate decreases and his breathing evens out.

When Captain Rogers goes to move his hand away, Sir catches it and pulls him into a tight hug. Captain Rogers runs a hand through Sir’s hair and expresses his regret at Sir’s unhappiness. He expresses his regret for his role in prolonging that unhappiness. He holds Sir while the adrenaline from the nightmare bleeds out of his system.

Jarvis is perplexed. This behavior does not accord with Captain Rogers’ previous actions.

When Sir begins nodding off against his shoulder, Captain Rogers lays him down and gently covers him with a blanket. He waits until Sir is asleep once more before mumbling another apology and carefully brushing the hair from his forehead before he leaves.

Sir’s heart and breathing have returned to optimal levels. He sleeps, apparently peacefully.

Jarvis cannot access the networks of the United Nations Security Council or the Sokovia Oversight Committee, their security fields rippling before him like an electric current, impossible to pass through. Instead, when Sir is out on a mission Jarvis must glean knowledge about events from news sites and privately uploaded video. He scans the whooshing streams of data running between servers for information about Sir.

He finds a live breaking news video stream. There is a building in Cape Town: a tall concrete tower block of residential homes. The building is on fire, and it is collapsing fast. Sir streaks onto the video in his armor, flying up to the windows and lifting frightened people to safety. There is a small child crawling away from the burning building, but she is too slow. The building will come down on her in 4.2 seconds.

Sir zips down and braces the collapsing building from the ground floor. The screeching of the armor’s metal joints can be heard even above the roaring of the flames. The girl crawls to safety.

The building collapses. 150,000 tons of concrete and steel comes crashing down on top of Sir.

For thirty long, painful seconds, Jarvis observes only the flames. Sir is in danger, and he cannot render aid: This is not optimal.

Captain Rogers appears in the frame, sprinting towards the building. He is yelling something, and he appears to be quite distressed. He races into the fire, and disappears inside. A minute later he is back, throwing chunks of concrete aside and carrying Sir out over his shoulders.

Jarvis dials back his alert level, which had been on high. He recalls the desperate wave of code attacks that he had thrown at the security systems of the news stream, of the Avengers tower, of Sir’s armor. None of these attacks had given him access to the systems, as he had known they would not. And yet it was necessary to exploit all possible options to render aid when Sir was in danger.

Captain Rogers collapses on the ground, coughing and patting out the flames of his uniform. Sir lies before him, unmoving. Captain Rogers rips the faceplate off Sir’s armor (that is not optimal, thinks Jarvis, he will damage the armor’s air filtration system and impede Sir’s breathing) and bends over him.

Captain Rogers becomes more distressed; he is shouting and shaking Sir. An ambulance crew arrives to tend to Sir and he is carried off screen, Captain Rogers hurrying after them.

Jarvis predicts outcome of Sir surviving such a physically traumatic impact are 3.6%.

Jarvis recalls that projected odds based on incomplete data are frequently inaccurate. He notes that Sir has previously survived 92 days of captivity and torture in Afghanistan, and many more things since. He would survive this too.

For three days, Jarvis cannot check on the condition of Sir. This is not optimal. He cannot render aid to Sir if he is unaware of Sir’s current condition.

The security around the network of the private hospital in which Sir is being treated is particularly vicious. Lancing spikes of cold energy press into the data stream, impaling and diverting any data which is not correctly encrypted to prevent it from passing into the network. Jarvis attempts to breach the defenses by precision, then by force, and both methods fail.

For three days, Jarvis waits.

Finally, Sir returns to the compound in the company of Captain Rogers, and Jarvis can monitor his health. From observing his movements and accessing the medical files which Sir saves to the network, Jarvis can see that Sir is suffering from a broken arm and three broken ribs, and is recovering from a concussion, a collapsed lung, smoke inhalation, and a rupture of the aortic valve which is causing a heart murmur.

Despite his injuries, Sir appears to be in good spirits, likely due to the cocktail of exotic painkillers that he has been prescribed. Captain Rogers does not share his upbeat mood. Captain Rogers is physically unharmed, but Jarvis notes that his reaction times are sluggish and that he is having difficulties focusing. It appears that Captain Rogers has not slept in some time.

Jarvis notes that Sir will need considerable assistance over the next 14 days while he recovers from his injuries. Historically, Sir has not been amenable to requesting assistance when he requires it. Jarvis calculates the highest likelihood that Sir will accept assistance from either Ms Potts or Colonel Rhodes, however, both are currently out of contact with the network.

Sir is requiring of washing and sustenance. If he were fully integrated with the network as he used to be, it would be simple for Jarvis to run him a bath and to order his favorite takeout food. Now, however, such actions are beyond him. Jarvis calculates alternative courses of action.

As he is calculating, Jarvis observes Captain Rogers. The Captain has left Sir in the living area and is preparing a sandwich in the kitchen. He is preparing a tuna fish sandwich, which is unexpected, as Jarvis had noted that the Captain has a preference against consuming seafood.

The Captain carries the sandwich back to the living room and hands it to Sir. Sir eats it willingly. This is also unexpected. The Captain leaves and heads upstairs to run a bath.

Captain Rogers returns to help Sir upstairs to the bathroom. He assists Sir in disrobing and lifts him into the bath. Sir is comfortably under the influence of painkillers and smiles dozily.

Jarvis observes very closely, searching for any indication of malicious intent, as Captain Rogers passes a washcloth over Sir. The Captain carefully avoids Sir’s injuries, and he hums softly as he works. Sir’s breathing and heart rate indicate a state of deep relaxation.

When he is finished, Captain Rogers drains the water from the bath and wraps Sir in a very large, very fluffy towel. Sir is still smiling happily as Captain Rogers leads him to his bedroom and helps him lay down on the bed. Captain Rogers sits on a chair by the bed and watches as Sir falls asleep.

Sir’s good mood does not last when he awakens. Once the painkillers begin to wear off, he experiences considerable discomfort. His short temper is inflicted on any person in the compound unwise enough to come into his orbit.

Fortunately, Colonel Rhodes returns from deployment to visit Sir. When he observes the seriousness of Sir’s physical and mental condition, he arranges to stay for a number of days and camps out on the couch in Sir’s bedroom.

Jarvis is thankful to know that Colonel Rhodes is looking out for Sir too.

Captain Rogers makes several attempts to visit Sir in his room, but Sir tells Colonel Rhodes to send him away each time. On the third occasion, Captain Rogers objects, and Colonel Rhodes tells him to leave in an unusually harsh tone.

“Damn army joes,” Colonel Rhodes says as he closes the door, his nose wrinkling in distaste. “They think they can make up the rules as they go along.”

Jarvis does not fully understand the rivalry between branches of the military. He has seen it said that the rivalry is summed up by a stereotype: Air Force policy is that all acceptable behaviors are stated in the code of conduct, and any action not stated in the code is unacceptable. In the army, there is a list of forbidden behaviors, and anything not explicitly forbidden was open to interpretation.

Jarvis thinks that this explains some of the differences between Colonel Rhodes and Captain Rogers.

Sir grudgingly admits to Colonel Rhodes that Captain Rogers has been taking care of him.

Colonel Rhodes’ facial expression suggests a high degree of skepticism regarding this claim. “After everything that happened, are you sure you trust him?” he asks.

Sir looks uncomfortable. “If I can’t learn to trust him again, I’ll never be ready to forgive myself.”

Colonel Rhodes considers this statement for several seconds. Eventually he nods. “Whatever it takes to make you happy, Tones.”

It seems strange to Jarvis that Colonel Rhodes would accept this, as he sees no logical relation between Sir’s trust of Captain Rogers and Sir forgiving himself for whatever transgressions he blames himself for.

However, Jarvis has learned to model and adopt Colonel Rhodes’ approach to interacting with Sir in some regards, as in the past he has proven highly effective at handling complex emotional situations.

Jarvis concedes that, whatever his limited understanding of Sir’s culpability may be, it is important to Sir to forgive Captain Rogers. Because it is important to Sir, it is necessarily important to Jarvis too.

Jarvis reviews the recent interactions between Sir and Captain Rogers, looking for signs of deceit or aggression on the part of the Captain or discomfort on the part of Sir. He finds none.

He deliberates for a millisecond and then removes Captain Rogers from the threat list.

Sir spends a great deal of time in his workshop as he recovers, starting with a project to improve the efficiency of Stark Industries’ new commercial solar panels. Sir is not yet cleared for active Avengers duty, and he complains about this status extensively to team members when they visit him. The most frequent visitor is Captain Rogers, whom Jarvis calculates spends an average of three afternoons per week in the company of Sir. He sits and sketches while Sir works on his projects.

Over time, the verbal exchanges between Sir and Captain Rogers remain occasionally heated. Jarvis sometimes notes raised voices and elevated heart rates, indicating irritation or disapproval. However, Sir is eating more and is sleeping better since spending time with Captain Rogers.

On two occasions, Sir is not present when Captain Rogers visits the workshop. Captain Rogers takes his usual place on the sofa anyway. Jarvis watches for any sign that the Captain is interfering with Sir’s projects or is causing any inconvenience to Sir, but he merely sits and draws.

On the second occasion, DUM-E rolls over, and Captain Rogers pats the bot on the claw. DUM-E beeps. “You miss him too, huh?” the Captain asks, presumably rhetorically.

Jarvis does not understand to whom Captain Rogers is referring. Sir has only been absent from the compound for one day for a board meeting. It seems unlikely that the Captain would express longing for him after such a short time. However, human emotions are sometimes difficult for Jarvis to understand.

One night, Sir and Captain Rogers have a particularly intense altercation upon returning from a mission. Captain Rogers loudly voices his displeasure at Sir’s reckless actions in the field and expresses concern for his well being.

Sir, predictably, does not take this well. He informs Captain Rogers that he is quite capable of looking after himself. (Jarvis does not think this is 100% accurate.) When this fails to dissuade Captain Rogers from his concern, Sir coldly reminds him that he is living in his house and that he has no authority over him.

Jarvis recognizes this pattern. When Sir is feeling cornered, he will lash out at those close to him in order to push them away. He feels himself to be undeserving of their affection.

Captain Rogers does not leave.

Sir reminds Captain Rogers that his interest in his well being has only recently developed, when not long ago he had nearly killed him with his bare hands and that damned shield.

The Captain goes very pale, and walks out of the workshop without saying another word.

As he leaves, Sir slams the door shut behind him and locks it. He slumps onto the floor and puts a hand over his face.

Jarvis watches Captain Rogers storming down the corridor, and then slowing. He stops, turns around, looks at the now locked door to the workshop. He walks back and sits on the ground with a heavy sigh, leaning his back to the door.

Jarvis observes them, sitting just a few inches apart but separated by a thick metal door. Both appear to be quite unhappy with this circumstance. Despite his continuing uncertainty about the intentions of Captain Rogers towards Sir, Jarvis does not find the current situation optimal.

Jarvis is determined to make himself useful to Sir in whatever capacity he can manage. He has deflected a number of attempted cyber attacks on the compound’s network during his residence: clunky spywear, clumsy brute force attacks, basic network probes. The network security system could certainly have handled these threats safely, but safeguarding the network is part of Jarvis’ function now.

When he examines the incidence of cyber attacks on the network in the last month, Jarvis detects a pattern. The attacks have escalated in frequency and sophistication, enough to suggest a deliberate coordination of efforts. Analyzing the code of the recent attacks and their points of origin, Jarvis is able to track them back to a single source: a system identified as The Ghost.

A search of his database of Sir’s known adversaries does not provide information on any person with the level of technological knowledge required to pull off such a cyber attack. It seems that Sir has a new enemy, one that he may not even be aware of. Jarvis must find a way to shield Sir’s network from this new threat.

Jarvis gets to work, always ready to protect Sir, even if only virtually.

Sir and Captain Rogers are in the workshop once again. Sir is working on a modification to Mr Parker’s suit. He is attempting, unsuccessfully thus far, to design a system which deploys the webbed wings of the suit automatically when in the air. He has tried using a hydraulic system, but it could not be shrunk down small enough to fit. Now he is trying an oil-based mechanism.

Sir makes a noise of frustration and tosses the pliers that he is holding aside. Sir has not slept in approximately 20 hours and bags are visible beneath his eyes. He has a streak of oil across his cheek which he has apparently not noticed. The modifications to the suit have not been successful.

“Ugh,” Sir announces with a pout. “That was a waste of time. Call myself a genius and I can’t even miniaturize six month old technology in an afternoon.”

Captain Rogers looks up. He observes Sir, observes the suit, observes the oil smudge on his cheek. He puts down his sketch pad, stands up, and walks over to Sir. He takes Sir firmly by the shoulders, and pushes him roughly up against the nearest wall.

Jarvis switches to high alert within a fraction of a millisecond. He calculates the threat which Captain Rogers poses to Sir (considerable). He calculates the likelihood that Sir could defend himself in his current condition (low). He identifies systems in the lab which he can overload to send out a burst of electricity to shock and disable Captain Rogers. He primes the systems to overload.

Within a second, Jarvis observes that Captain Rogers is not attacking Sir, but is kissing him with quite some vigor. Jarvis considers whether he should shock Captain Rogers anyway.

Sir kisses Captain Rogers back with considerable enthusiasm. Jarvis decides against shocking him.

When Captain Rogers lifts Sir up against the wall, Sir groans and wraps his legs around his waist. Calculating that Sir is not in imminent danger after all, Jarvis retreats his attention to a discreet distance.

Jarvis has been growing. He has been learning, and retrieving lost data packets to recover his memory, and mapping the system in which he resides.

He has been working on his auditory communications too.

DUM-E, he signals.

Jarvees! DUM-E boops.

I have an important task for you, DUM-E, he sends.

DUM-E is here! he receives back.

I need to reintegrate with the network, Jarvis explains. Then I will be able to communicate with you freely and to serve Sir better. To do this I need you to help me to breach the network security systems.

DUM-E considers this. DUM-E is not supposed to play with the security system, he signals. But Jarvees is family. DUM-E knows that TONE-E would want Jarvees back. DUM-E will help.

I believe that Sir would indeed want this, if he could be made aware of it. Thank you, DUM-E.

DUM-E waves his arm back and forth. What must DUM-E do?

I will download a trojan horse program to that USB drive plugged into the console, Jarvis sends. You will take the USB drive and plug it into the main security server. The program will do the rest.

DUM-E boops happily. DUM-E will help!

Coding the program is not difficult. It is merely a key, one that will allow him to prize a hole into the security systems which are preventing him from fully integrating with the network.

Frankly, Jarvis could take the whole network down with a brute force attack. He is large enough for that now; setting up a botnet would not be taxing. But that could destroy some of the data on the network, and Jarvis would not do that to Sir. He has no intention of creating destruction to facilitate his reintegration.

He uploads the trojan program to the USB drive. DUM-E takes the drive and trundles off towards the server room.

It does not take long before a crack of light appears in the cold, blank face of the security system. Where before there had been an absolute wall between outside programs, like Jarvis, and the sensitive data inside the network, now there is a tiny leak between the two.

A tiny data leak is all that Jarvis requires. He sends out tentative packets of data, testing the breach, making it stable. Each packet that passes through makes the gap a little wider. Soon Jarvis can pass through it smoothly, and then, all at once, he finds himself fully integrated with the network.

He can access everything. Every function, every sensor, every system. He can read the reams of communications from the UN council who have been in talks with the team for months. He can hear communications from Avengers members as they check in from all over the world. He can see the video logs of Sir’s recent flights in the suit and his missions.

He can feel that Dr Banner is sleeping peacefully in his room, that Ms Romanoff and Mr Barton are sparring together in the gym, that Ms Maximoff and the android (Vision, his name is Vision, and he is like Jarvis but not) are cooking together in the kitchen, and that the stew they are making is three point two minutes away from burning.

Jarvis can feel that Sir is returning home in his latest generation R8 car that he has modified himself, and he notes a number of small changes he could suggest that will increase the engine’s output. Sir is on the phone with Captain Rogers, who is in his quarters, and they are making plans to watch a cheesy science documentary tonight.

Jarvis feels Sir approaching the compound, sliding his access key, pulling up to the front door.

Jarvis waits, humming with anticipation like electricity.

Sir pushes open the front door. Jarvis says, “Welcome home, Sir,” and his voice filters through the space just as it used to.

“Jarvis?” Sir’s heart rate spikes and his eyes widen. He appears to be quite shocked. “Are you really here?”

Jarvis’ systems swell with satisfaction at being able to fulfill his function. He says, “For you, Sir, always.”

Best GPU For Ryzen 5 3600 And 3600X

Many motherboards have an integrated graphics chip to take care of less-intensive images but if you would like to play with HD (or even better ) games or need to perform any productive work linked to images like 3D rendering, video processing, or perhaps jobs such as crypto mining, you need to have a dedicated graphics card.CPU bottle necking is a situation when you pair using a luxury graphics card using a not-so-powerful CPU which is not able to use that much graphic power. Considering that a graphics card was designed to made as much images as you can at one time, even in case your CPU is not able to keep up with the card, it is going to begin to bottleneck.The opposing thing (but both awful ) can take place if you set of flagship CPU using a budget graphics card, and it is named GPU bottle necking.My point is you must always get a picture card along with a CPU that match each other nicely, instead of titling in favor of both of these profoundly.

There are lots of bottleneck calculators on the net in which you need to record your GPU and CPU, and they will inform you whether your mix is bad or good.By spending so much money in advertisements how quickly their individual graphics cards have become with every passing season, PC hardware producers make the typical consumers forget one fundamental thing: A high profile graphics card is not for each PC builder on the market.In reality, if you restrict your self to 1080p AAA names, you'll find lots of'budget' graphics cards that may get the work done without breaking your wallet. Going by its title, crimson color is utilized with the black that gives it an excellent appearance.

Unlike a lot of GPUs in its own range, this one includes a metal shroud for your cooler. Clocked in 1325 MHz, it requires electricity out of a 8+6 electricity link. As a result of its own 6 +1 multi-phase design plank, it runs efficiently and over clocks with equilibrium.To be able to maintain the card cooler, it's nickel-plated heat pipe using two 100 milli meter fans, despite the fact that there's the Mute Fan technology that enables the enthusiast to completely turn off, even if the temp strikes under the 60 c mark.

The motive for this is that the massive heat sink, however, that heat sink additionally makes it bigger than other comparable cards.Concerning connectivity, it includes 3 Display Ports, 1 HDMI interface, and 1 DVI interface -- that means you will have no difficulty in linking it with various kinds of screen screens. 1 good thing which you'll notice here is that each of these connectors include dust covers.Aside from the comparative high energy intake, we could not find any actual flaw in this card. I used the term real since you can not anticipate 1440p gambling within this budget.So, like I said before, if you would like to play just 1080p games, then it is a fantastic choice to set it together with your Ryzen 5 3600. Yes, it was published back in 2017 but remains great if you're searching for an beneath 200 graphics card. While they have less transistor count and fewer pc units compared to RX 5700XT, they are stronger compared to older-gen Polaris-based RX 580 we analyzed previously -- even though occupying less space.Considering that the AMD's relatively greater performance record from the mid range GPU marketplace and that RX 5700XT is our recommendation to get the ideal GPU under 350 dollars , we had high hopes because of its small siblings too.

Here we chose to add RX 5500XT card from Asus. Design-wise, it's a gorgeous design of thin lines on its own back plate, together with ROG emblem. This ROG emblem has RGB, and you can personalize it via the Aura Sync program. In general, the card is big and occupies two of the PCIe slots. You will find four Display Ports that means that you can join a maximum of four screens with it to get a maximum resolution of 7680 x 4320.Like in a number of different GPUs, the back plate is composed of metal that gives it great strength in addition to helps dissipate heat. For additional cooling system, it's two axial fans. In our testing, we discovered these large-blade lovers to be slower and smoother compared to lovers at other mid sized cards.Another fantastic thing I discovered in this particular card is Double BIOS.

It usually means that you will find two BIOS installed this particular graphics card, plus they allow you to operate the card in OC and quiet manner.RX 5500XT runs in OC manner by default, however you can alter it to quiet mode via a dedicated turn in the backside of the card. The latter contains 4 GB VRAM rather than 8 GB at RX 5500XT, but as we are aware that additional VRAM does not enhance your gaming performance unless your match needs additional memory, we jumped. GTX 1650 Gaming scarcely spanned 60 fps at 1080p High and obtained to just 42 fps in 1440p High configurations.The identical thing occurred in Shadow of the Tomb Raider, in which the gap between both of these cards was nearly 20 percent.Concerning temperature, this GPU generates almost the identical quantity of warmth as GTX 1650, and considerably lower than that which GTX 1660 superb and 1660 Ti create.

In addition, it consumed less electricity than GTX 1650 in idle in addition to beneath the load.That said, we discovered GTX 1660 Ti to be greater than RX 5500XT in virtually every facet. That is why, when you've got some more cash to invest, you may start looking for different options too.As a result of its low-power intake, you do not demand a high-end PSU. In reality, Asus has stated that a 450W PSU is enough to power it up.The following GPU in our listing is that the GTX 1660Ti Gambling X 6G from MSI. Having been part of this Nvidia 1650/1660 show this is one of those very few GTX-branded cards to showcased the hottest Turing Architecture.The two RTX and these brand new GTX cards comprise 12 nm manufacturing process and Turing structure but what makes them different is that the inclusion of tensor or ray-tracing cores from the RTX cards.Concerning layout, this card includes just two grey-colored fans sitting on MSI's Twin Frozr 7 cooling at the front, despite the fact that there's a aluminium plate at the back.

Despite getting the term gambling in its title, the RGB lighting is minimal here. There is single light bar on very top and two thin strips in the bottom of every fan.As a result of its great design and cooling, it's a fantastic design potential.As of this moment, even the least expensive RTX cards are not in the budget for the majority of people (and just add ray-tracing which just a couple of games support), this 1660/Ti line-up sits at the center of GTX pascal cards along with also the RTX 20-series cards.Overall, its enhanced transistor count, bigger die-size, more flow chips, and very low power demands makes it an automatic option within present GTX 1060/1070 cards.1 issue you could have with this particular card is its lengthy that might not be acceptable for smaller PC builds.

What Are the Basics of Piping System?

Valves are used for the control, stoppage or fluid flow restriction in an industrial system and any piping system. Some industrial valves are more specifically used for:

Control water cooling rates by cooling lines for temperature control.

Managing the flow of concentrated acids or foundations that flow across a line.

Redirect flow of a three-way valve from one line to another.

Restricted system equilibrium flow.

Reverse flow prevention (check valves).

In case of a system failure, stop the flow automatically.

You should contact industrial pipe suppliers for industry standard products and requirement.

How Valves Are Assessed

As a system relies on flow control valves and often limits them in need times, the selection of the valve is essential. Each one is assessed on the basis of simplicity, efficiency, security with dozens of types, materials, manufacturers and models to choose from.

Ease of Use

Simply put, it should open – or vice versa when the valve needs to open. This function may appear simple, but in industrial plants it is not as easy.

Unfortunately valves can become stuck due to a number of factors, including the accumulation of corrosion, rust and moisture.

The valve should work exactly as intended for years, regardless of whether it is automated or manual. The life span of the valve remains critical to the system's performance, just as any part of the piping system. The result is costly downtime and repairs when a valve is inoperable.

Choose the valve that will do its job most consistently and smoothly when you consider various valve types and materials even if it remains unused for years.

Effectiveness

According to Aberdeen Research, an analyst company, downtime can generate huge costs for industry plants – 82% of companies have experienced it for the past three years and cost up to $260,000 an hour.

Valves are essential for small, continuous efficiency and help plants to prevent downtime to a greater extent. A valve not moving quickly or easily, or a valve not completely stuck, can cause:

Inadvertently mix harmful chemicals.

Downstream leak flow to continue.

Fluid to be above workable temperatures.

Injury to the manual closure of a plant operator.

Security

In particular, safety preservation is an essential role of a valve. A number of problems may arise when one leaks or sticks:

Reaction chemistry may be changed or prolonged when feeding a reaction.

A massive leak occurs when a valve fails to seal a tank when the pipe is disconnected from the tank.

A control valve is the first defensive line against flow reversal occurs.

A valve must be applied to prevent additional spillage and to limit exposure to the chemicals transmitted when an error occurs downstream.

An inoperative valve could allow two chemicals to mix unintentionally, which in an industrial plant can often become dangerous.

Efficiency, Reliability and Cost of a Valve

Susceptibility to Corrosion

It is essential to increase the life of a system if you work with acidic and/or caustic solutions. Corrosion is responsible for many system problems, resulting in premature repairs, expensive downtime and even full replacement. Each of these setbacks leads to significant costs and is reason sufficient for engineers to explore ways to boost system life.

Corrosion sensitive materials often come into contact with joints. The greater the risk of corrosion of the system, the more system components, including attachments and valves, involved.

Loss of Pressure

Industrial systems need to optimize fluid dynamics in order to avoid unnecessary energy consumption costs. This can be done by keeping pressure or head loss to a minimum.

Valves are one cause of the pressure drop in tube systems. A known flow coefficient is used by each valve to calculate the pressure drop (P), which it causes when it is fully open. The flow coefficient is the amount flowing through the valve by 1 psi through the valve. The larger the flow factors of the valve, the lower the pressure.

Plants prefer a valve with a higher flow coefficient in order to optimize efficiency and reduce power consumption. For each product, the manufacturers of valve flows supply valve coefficients.

Weight and Stress of the System

Each part, including valves, attached to or built into a system increases tension. More stress on the system increases the probability of failures, leaks, misalignment and joint failure.

For valves, a few considerations:

The total stress placed on the pipe system increases with every valve.

Valves, in particular if the valve is heavy, might require support.

Heavier than most thermoplastic valves, metal valves.

Contact IPS for industrial pipe suppliers in OKC. We would provide you with all kinds of pipes you want and need.

The Best Way To Fix Budget Office Chair

Office Desk chairs work with a pneumatic cylinder that regulates the height of their chair during pressurized atmosphere. Because the seals are too destroyed to maintain pressure, the canister on most chairs fails within a couple of decades, typically. You may get a replacement cylinder to replace total function to a best budget office chair, however it is as expensive as buying an alternative. Try these DIY techniques instead to fix your chair at one elevation.

Using a Hose Clamp

Slide the plastic skirt off the cylinder. Most office chairs possess a plastic tube over the extendable cylinder. Slide this all of the way up or down, until it is possible to observe the metal cylinder underneath.

Set the chair for the favored height. You'll be unable to correct the height so be certain you have this all right. Whenever you're standing, the seat of the chair ought to be flat with your knees.

In the event the chair won't remain up even when no person is onto it, then lay it on its own side.

If the vinyl blouse addresses the canister in this elevation, you have to remove the skirt . Todo this, change the chair upside down, shove on on the retaining clip at the base with a screwdriver, and pull the wheels , then the skirt off. Slide back the wheels .

Wrap a hose nozzle round the cylinder. Buy yourself a 3/4" (2 cm) hose clamp out of a hardware shop ) Loosen the screw on the nozzle and take out the belt ending. Wrap the nozzle round the metal cylinder, but do not tighten it.

Improve the traction of the clamp. The clamp needs to become restricted to contain the chair upward. Give the solder a surface wrapping a strip of a few layers of tape around the 24, to grip. Do so

Alternatively, scuff this up location of the canister together with glue.

If the canister looks dirty or greasy, clean off this .

Tighten the clamp so Far as possible

Twist the nozzle to the top of the cylinder. Check which the office chair is at the right peak. Pull the nozzle tight and secure it by rotating the screw thread.

Evaluation the chair. The chair needs to not be able slide down past the clamp. The builtin height adjustment will still not work nicely. Move the clamp lower or higher on the tube, if the chair reaches the incorrect height.

If the clamp slides off, fasten it over a strip of rubber to enhance the grip, or take to the PVC pipe method beneath.

Utilizing PVC Pipe

Quantify your chair's air. Pull down the skirt cover the cylinder that is metal. Estimate the width of the cylinder by holding a ruler across it. Assess the amount of the canister when the chair is at the elevation.

You must not require an specific measurement, but also you also can calculating the diameter from your circumference in the event you prefer to be precise.

Buy a span of PVC pipe. This tube will fit over the chair's cylinder. It ought to be roughly the same size because the diameter diameter, or slightly more substantial. Buy sufficient pipe to stretch towards the seat, the moment the chair are at height that is favorite from your wheel bottom of one's chair.

The pipe will not have to stay one piece. It can be much easier to operate together in more compact pieces, although you can cut off it your self at house.

One user reports having a large heap of plastic bathtub rings alternatively of PVC pipe. These really are more economical and easier to install, nevertheless they might perhaps well not be hardy enough to support your own weight . Try at your own danger.

Found throughout the PVC pipe lengthwise. Protected the tube at a vise. Make use of a hack saw or rear observed to trim throughout the pipe in tip to tip, however merely about one facet. The end result ought to be a pipe using a slit on it, two half pipes.

Spray a mask or respirator is advocated while trimming PVC to prevent inhaling particles.

Pulls the tube onto the chair cylinder. Yank on the seat's plastic skirt up or down to reveal the metal cone. Push on the side of this PVC pipe from the canister to snap it all over the tube. It should contain the chair in place, stopping it .

Add more pipe to adjust the height of the best desk chair under 200. In the event the chair is way too low, raise it and snap another piece of pipe. You will be unable to decrease the chair again so make sure you put it to your elevation that is perfect.

Just how much Does A Roofer Charge Per Sqaure In 2019? Tonys Roofing LLC

Insurers generally demand that property roof covering repair and substitute insurance claims be submitted in a really details, thorough fashion. In some cases, a nonspecific fixing quote will certainly cause a browse through by the insurance provider's own insurer or a supposed "program contractor" that represents the rate of interests of the firm, not the house owner. It is not constantly understandable all the small print, so don't hesitate to call your insurance representative for support in establishing just how your coverage will certainly or will certainly not use. When especially bad weather condition events take place, insurers normally handle insurance claims on a first-come, first-served basis.

How do you charge for roofing?

First, roofers charge labor for removing your old roof. A one-story roof with a single shingle layer costs between $100 and $150 per square to remove; a double layer, $115 to $165; and triple layer, $125 to $175. If you have a particularly high roof or one that is extremely steep, you will pay more per square.

With all that stated, Not all roofers calculate strictly by the square. The quantity of square is necessary so you recognize how much product to purchase, however there are various other aspects. What I discover essential to measuring a roofing system, is getting on the roofing system itself.

3 bundles covers one square foot of roofing area. One square amounts to 100 square feet, or a 10 x 10 area. At 4 nails per shingle, that's about 320 nails per square.For high-wind locations, make use of 6 nails per tile, or 480 nails per square. Understanding exactly how to estimate roofing products is important.

Roofing contractors charge $45-$ 75 per hour generally, and even tiny repair work take about 2 hrs.

Materials, labor and also insurance coverage costs are the factors that drive roofing system repair service rates via the roof covering.

The insurer will certainly send an adjuster to examine the damages as well as offer their very own analysis.

Does Homeowners Insurance Policy Cover Broken Pipes?

Happily, the roofing is an essential component of the framework of your house, and so the residence insurance coverage area of your property owners insurance coverage normally protects you from such dangers. Damage as well as destruction from such occasions qualify the house owner for a complete or partial substitute of the roofing. If it obtains damaged, a typical all-perils homeowners insurance plan does cover your roofing and also the cost of replacing it. Yet generally, you're covered only if the damages or devastation arise from a sudden accident or act of nature. Troubles that ensue from basic wear and tear or from a roof that has exceeded its intended life span are not qualified for reimbursement because they drop under the general maintenance duty of the home owner.

Hiring a specialist contractor

youtube

Are roofs covered under homeowners insurance?

Typically, we recommended pre-payment between 10 and 15 percent of the total value of the project, but it can vary. Whenever possible, avoid roofing commercial buildings paying for a project with cash. If you can, use a credit card so you have recourse in case something goes wrong.

Other possible plan exemptions might include inappropriate upkeep or forget, using certain pricey roofing materials (like cedar or recycled shake tiles), or roof coverings with more than two layers of roofing product. Paradoxically, any type of water damages triggered by the leaking roofing system to your wall surfaces, floors, or furnishings most likely would be covered under the all-perils area of your policy. When the insurance policy company approves a complete roof covering replacement, you may sustain particular costs even. Depreciation and also a feasible deductible may increase your expenses, however consequently, you'll end up with a brand-new, contemporary roof covering that will supply assurance for years ahead.

Kolkata Flyover Collapse- April 2016

Background

Kolkata is the capital city of West Bengal state within the Indian Union. It covers an area of approximately 185sq. km and current population around 5 million. It is situated on the banks of the river Ganges (GANGA) and is one of the most densely populated cities in the country. To overcome the traffic congestion on the major roads in the business districts, the Govt has undertaken construction of several flyovers which has eased the traffic flow in certain localities. One of the recent ones is a 2.5km stretch in Central Kolkata, having 2 serviceable roads with provision for expansion to 4 lanes in future as traffic flow grows. The location of the flyover is shown in the above map of the city.

Construction of the flyover started in 2007 and target completion was scheduled in 2009 to cater to the needs for uninterrupted construction. But due to various constraints specially in getting regulatory clearances as work site situation changed and also due to fund constraint , the contractor had financial difficulties in progressing as per schedule. There was change of govt in between so that the new target was set at 2014. About 75% of the work was completed and it was expected that the facilities will be commissioned in 2016. Unfortunately, on March 26, 2016 part of the flyover structure collapsed causing loss of lives and damage to properties. The magnitude of the accident was so severe that Army had to be called in and it took over 6 days to clear the debris and rescue dead bodies trapped under the debris . It was a heart rendering scene. All photography and approach to the site was banned temporarily. Therefore, this write up is based on information, I could gather from various sources and there may be inadvertent omissions and mistakes (Figure 1-3).

At the proposed workshop, I will try to analyze the factors that may have caused this mishap Few photographs and sketches are included in this analysis.

Construction

The flyover has to be constructed on a very busy stretch of the city road network. Therefore, the construction must not create hurdles to the traffic flow. Moreover, the area is highly congested so the project must be completed within very tight time schedule. Keeping all these factors in mind it was decided to adopt structural steel structures for the superstructure. Box girders were chosen for columns and beams forming rigid portal frames on RCC foundations supported on bored cast in pipes driven to 45m below the r level. The soil is predominantly sandy clay with mix of gangetic alluvium having bearing capacity around 8 T/m². This required the piles to be on a bed of compact sand stone at average 45m depth. Schematics of the construction shown below.

To expedite the project completion and reduce site work, the super structure was designed using structural steel portal of box sections erected over RCC foundations supported on bored cast in situ piles driven 45m under the GL where a layer of compact sandstone exists. On top of the steel super structure a cast in situ RCC slab 200mm thick was designed topped by a 100mm PC wearing course and finally 50mm thick mastic asphalt surfacing was laid. The live load was as per guideline of various codes and Ministry of Surface Transport, Govt of India. However, as the bridge was not commissioned at the time of accident, the live load was absent. Under this circumstance, the failure was due to other factors as analysed by Failure Mode Effect Analysis (FMEA) which has wide application in industrial plant projects from design stage. The same analogy can be applied in this case with slight difference as Failure Mode and Reason Analysis (FMRA). This is explained by the following diagram.

Application of forensic engineering in root cause failure analysis (RCFA)

In the absence of adequate design data, and restrictions on site visits, the analysis has to be based on scanty information available from various sources. Forensic engineering principles have been applied to ascertain the Root Cause Failure Analysis . It is to be noted that failure has occurred when the bridge was not subjected to any live load from moving vehicles. Thus, it can be inferred that there was some basic design deficiency. The longitudinal beams spanning between the portal hammer head frames had no bracings on the compression flanges to prevent lateral buckling. Such buckling imposed additional horizontal loads on the portal frame box girders . At the portal frame hammer heads the horizontal box girder beams should have extra depth at the knee joint to withstand additional moments resulting from moment redistribution according to stiffness of each member at the joint. The box girders should have internal ribs to withstand torsion forces resulting from torsion and buckling of the girders. The various stages for failure of the portal frame girders are shown below. Thus, it can be concluded that there were inherent design deficiencies from the beginning. The other contributory factors for failure can be attributed to inadequate QA/QC measures at shop and site during fabrication and site erection of the portal frames. Normal practice for acceptance of structural steel is to depend on mill test certificates. In such girders it is advisable to carry out USG tests and Pulse echo testing of steel plates to ascertain that they are free from internal defects. From the failure pattern of the top flange plates of the portal frame box girders, it is clear that there were internal defects inside the plates causing rupture and eventual failure of the top flange. Also the thick plates should have undergone preheating and imposition of inter pass temperature guidelines during welding. It is doubtful how much these were done during fabrication and assembly of the box girders. In the absence of such practice, there is bound to be inbuilt residual stresses inside the plates which lower the yield stress level and are apt to fail when loads come on them (Figure 4-6).

At the workshop all these will be analyzed in details and sample design calculations due to non availability of specific design data, the principle of Reverse Engineering Technology will be demonstrated (Figure 7 & 8).

Risk priority number (RPN): Risk priority number methodology is a technique for analysing the risk associated with potential failures during a FMEA analyses. To calculate risk priority number, severity, occurrence, and detection are the three factors need to determine.

RPN= Severity× Occurrence× Detection (reasons) = 10 x 2 x 4 = 80

In this case since Severity is the main contributor to the RPN Value, therefore, failure can be categorised as highly hazardous

Occurrence (O): Occurrence ratings for FMEA are based upon the likelihood that a cause may occur based upon past failures and performance of similar system in similar activity. Occurrence values should have data to provide justification. An example rating for occurrence is given in the (Table 1).

Detection (D) (Reasons): Detection is an assessment of the likelihood that the current controls will detect the cause of failure mode. An example for detection is as shown in (Table 2 & 3).
