Types Of Flow Measurement Devices

In the dynamic realm of industrial processes, the accurate measurement of fluid flow is crucial for efficiency and performance. In this article, we delve into the different types of flow measurement devices that play a pivotal role in optimizing processes across various sectors.

Electromagnetic Flow Meters: In applications where the fluid is conductive, electromagnetic flow meters shine. These devices utilize Faraday's law of electromagnetic induction to measure the velocity of the fluid. The resulting data, combined with the pipe's cross-sectional area, provides a precise measurement of the flow rate, making them ideal for industries dealing with water or other conductive liquids.

Ultrasonic Flow Meters: Employing ultrasonic waves to determine the velocity of fluid, these non-intrusive devices are gaining popularity. Transit-time and Doppler are two common types within this category. Transit-time ultrasonic meters measure the time it takes for ultrasonic signals to travel with and against the flow, while Doppler meters use the frequency shift of reflected waves to calculate flow velocity.

Coriolis Flow Meters: Renowned for their accuracy, Coriolis flow meters operate on the principle of the Coriolis effect. As fluid flows through a vibrating tube, the Coriolis effect induces a phase shift, which is proportional to the mass flow rate. This technology is particularly effective for measuring both liquids and gases with high precision.

Vortex Shedding Flow Meters: Capitalizing on the phenomenon of vortices forming downstream of a bluff body placed in the fluid stream, vortex Shedding flow meters are apt for measuring the flow of gases and liquids. The frequency of vortices shed is directly proportional to the flow rate, enabling accurate measurements.

In conclusion, the world of flow measurement devices is as diverse as the industries they serve. Each type has its strengths and applications, catering to specific needs and scenarios. As industries continue to evolve, the synergy of these devices with cutting-edge technologies ensures that accurate flow measurement remains a cornerstone for optimizing processes and enhancing overall efficiency.

Unveiling the Excellence of the Itron Water Meter: A Comprehensive Review

Introduction In the realm of industrial equipment, precision and reliability are paramount. As an esteemed member of Thiết Bị Công Nghiệp Sài Gòn (TBCNSG), I am thrilled to present a detailed review of the Itron Water Meter—an indispensable tool for measuring water flow. This comprehensive assessment aims to shed light on the key features, benefits, and overall performance of this cutting-edge…

[reasonsforhope]

"A team of researchers at Washington University in St. Louis has developed a real-time air monitor that can detect any of the SARS-CoV-2 virus variants that are present in a room in about 5 minutes.

The proof-of-concept device was created by researchers from the McKelvey School of Engineering and the School of Medicine at Washington University...

The results are contained in a July 10 publication in Nature Communications that provides details about how the technology works.

The device holds promise as a breakthrough that - when commercially available - could be used in hospitals and health care facilities, schools, congregate living quarters, and other public places to help detect not only the SARS-CoV-2 virus, but other respiratory virus aerosol such as influenza and respiratory syncytial virus (RSV) as well.

“There is nothing at the moment that tells us how safe a room is,” Cirrito said, in the university’s news release. “If you are in a room with 100 people, you don’t want to find out five days later whether you could be sick or not. The idea with this device is that you can know essentially in real time, or every 5 minutes, if there is a live virus in the air.”

How It Works

The team combined expertise in biosensing with knowhow in designing instruments that measure the toxicity of air. The resulting device is an air sampler that operates based on what’s called “wet cyclone technology.” Air is sucked into the sampler at very high speeds and is then mixed centrifugally with a fluid containing a nanobody that recognizes the spike protein from the SARS-CoV-2 virus. That fluid, which lines the walls of the sampler, creates a surface vortex that traps the virus aerosols. The wet cyclone sampler has a pump that collects the fluid and sends it to the biosensor for detection of the virus using electrochemistry.

The success of the instrument is linked to the extremely high velocity it generates - the monitor has a flow rate of about 1,000 liters per minute - allowing it to sample a much larger volume of air over a 5-minute collection period than what is possible with currently available commercial samplers. It’s also compact - about one foot wide and 10 inches tall - and lights up when a virus is detected, alerting users to increase airflow or circulation in the room.

Testing the Monitor

To test the monitor, the team placed it in the apartments of two Covid-positive patients. The real-time air samples from the bedrooms were then compared with air samples collected from a virus-free control room. The device detected the RNA of the virus in the air samples from the bedrooms but did not detect any in the control air samples.

In laboratory experiments that aerosolized SARS-CoV-2 into a room-sized chamber, the wet cyclone and biosensor were able to detect varying levels of airborne virus concentrations after only a few minutes of sampling, according to the study.

“We are starting with SARS-CoV-2, but there are plans to also measure influenza, RSV, rhinovirus and other top pathogens that routinely infect people,” Cirrito said. “In a hospital setting, the monitor could be used to measure for staph or strep, which cause all kinds of complications for patients. This could really have a major impact on people’s health.”

The Washington University team is now working to commercialize the air quality monitor."

Holy shit. I know it's still early in the technology and more testing will inevitably be needed but holy shit.

Literally, if it bears out, this could revolutionize medicine. And maybe let immunocompromised people fucking go places again

Also, for those who don't know, Nature Communications is a very prestigious scientific journal that focuses on Pretty Big Deal research. Their review process is incredibly rigorous. This is an absolutely HUGE credibility boost to this research and prototype

CHILDHOOD FRIEND

✶﹒ yandere! kim raebin x childhood friend! reader

honestly, i can't see kim raebin getting close to a woman who is completely stranger to him. so, let's just say that you were the daughter of their neighbour who is also his childhood friend.

we all know how introverted kim raebin was, so you had a hard time on getting close with him. because he always avoids you, or if you ever found a perfect time to talk to him, he always hisses making you blink. because for someone who looks like a bunny, kim raebin sure acts like a cat around you.

but wanna know how the two of you got close to each other? it's simple. it's because kim raebin accidentally saw you playing a guitar at a school event back when the two of you were in third grade. and boy, he was overjoyed! because this was the first time that he saw someone interested in music just like him!

at first, kim raebin was really shy when the two of you played or rather spent time together while playing various music instruments or making songs. but expect that after that, he would be so clingy. clingy to the point that he would follow you around like a damn puppy. at first, you thought that it was cute— not until you knew that he started stalking you around when you didn't hangout with him for a few days because you were too busy with school works.

what did you do? of course, you confronted him. but look, even though kim raebin has a problem when it comes on socializing with other people. it wasn't the same with you, because this guy knew everything about you. from your likes and dislikes, your habits, hell, even your measurements! that was the main reason why he easily changed the flow of the argument. he easily made you think that you are the one who's imagining that he was stalking you just because you missed hanging out with him, damn this smart guy.

kim raebin is so damn good when it comes to manipulating you into thinking that you were always the wrong one. forcing you to hang out with him without you thinking that he is actually forcing you. but, don't worry because kim raebin will never hurt you, he swear.

that's why when you heard that he got scouted on a certain entertainment company. you were overjoyed about this. because raebin will finally be able to achieve his dream and of course, you will be able to escape his clutches.

but, boy! kim raebin is a smart guy. because a year after kim raebin became a trainee, you got scouted too, by the same company that scouted kim raebin. how did that happen? you have no fucking idea. the only thing that they said is that they liked the song that you sent to them when you didn't actually send them one of your pieces. but who in the hell did sent it to them? you couldn't helped but to wonder. of course, it was a certain black-haired bunny who was overjoyed when he saw you confusedly stepped onto the company. and kim raebin— along with cha eugene who pestered raebin to introduce him to you welcomed you with the usual excited expression of his.

fast forward, when raebin debuted on testar, you also debuted and became the main vocalist, main rapper and lead dancer of your group. raebin liked the fact that everyone shipped the two of you. when does it start again? when you and raebin got invited to a certain variety show where the two kpop artists got partnered with each other and do certain tasks to see how compatible they were with each other. and seeing how the two of you easily do those tasks without even getting shy with each other, the host couldn't help but to ask the reason behind it. and when the two of you said that you were childhood friends. the internet got into chaos, fuck, childhood friends? everyone loves that kind of trope!

and now, he can visit you anytime he wants. seeing you and him eating together? it's fine, you were childhood friends after all! but seeing you getting partnered with a kpop artist who is not raebin? expect that everyone will criticize that idol because of that.

and raebin was satisfied with what was happening. he loved the fact that he was able to tie you down with him without you realizing it. it's fine even if you get into a secret relationship with other famous people. because once that was discovered by the public. he just needs to act pitiful and his and your fans will do the work to force you break up with whoever that guy was.

look, he likes you. he respects your decisions and choices but seeing you with other people makes his skin crawl. so, can you stay with him and do him a favour just like the old days, will you? because if you do that, he will gladly remain still and take care of you and protect your career.

“ i'm doing you a favour, you're just too irrational to see that right now, (first name).”

What if the slasher/s are trying to kill a victim but they are immortal and keep coming back

And the victim keeps following the slasher only to annoy and be a little menace to them >:3

(maybe they fall in love later O.O)

What ever slasher you choose is fine for me ;)

Art the clown x immortal!reader

Tw: blood, murdering, torturing? well, yeah. Art is an ass sometimes

• Art has always been a fan of violent and noisy 'games' that chilled the blood in his veins. That was his sadistic nature, and the whole of Miles County and people for hundreds of miles around had already heard a lot about it. A strange man in a clown costume, who sent at least a dozen unhappy teenagers and adults to the next world. He loved blood and horror, and no one would dare stand in his way, not wanting to become another victim of brutal violence.

• Maybe it was fate's will, or maybe it was just your bad luck or an accident, but one day Art saw you in one of the cafes late at night. He was watching you from a dark alley, so it's unlikely that you would have seen him even if you really wanted to. He clutched his garbage bag in his hands, and a cruel grin appeared on his face. You were a good little thing and you definitely could have brightened up this cold night for him.

• Without thinking for long, Art hit you on the head at the most unexpected moment and took you to one of his 'game rooms', which in fact was just a room of one of the old factories in the city. He wasn't in the mood to hunt you down and catch you in your own house for a long time. This game was supposed to be fast but colorful.

• The clown involuntarily licked his lips, watching you slowly regain consciousness and open your big innocent eyes. He walks around you like some kind of fancy Christmas tree. You're sitting on an old wooden chair, badly scratched and already soaked in blood from past victims. Your limbs are tied in wooden material with strong leather straps, and thick barbed wire with rusty, blunt teeth is wrapped around your neck, chest and abdomen. There was a smell of dampness and fear in the air, which made the Clown giggle noiselessly.

• Finally, Art stopped right in front of you and gestured at the trash bag to your right. Making a playful, almost pretended sweet expression, or reached into the bag as if looking for a Christmas present for a small child. In the flickering light, a long thin tool with a convex handle and a bizarrely curved metal tip appears, more like a sharply sharpened blade. A man comes behind you and caresses your tense shoulders with almost uncharacteristic tenderness. His fingers are rough and rough. The clown's palms slowly descend lower, sliding along your clothed back through the open part of the back of the chair. The movements are slow and measured. Suddenly his movements stop and in the next moment they are replaced by acute pain. Sparks dance in your eyes and you emit a strangled cry, reflexively your body gives way forward, blunt spikes painfully dig into your tender flesh. Art laughs soundlessly, continuing to press the blade deeper into your spine, and then abruptly moves his hand down. With a nasty creak, the fabric of your T-shirt is torn, and at the same time your soft flesh is torn. Art rejoices, seeing how his hands and white gloves are stained with maroon lingonberry liquid, flowing in a thick stream onto the concrete floor. Tears are pouring from your eyes as you desperately bite your lower lip in an attempt to control yourself. Your back, which was once a flawless canvas of pale skin, is now covered with a network of terrible red lines, each of which testifies to the cruelty of Art's tools and his relentless thirst for suffering. There is a pungent smell of iron in the air, mixing with the acrid smell of fear that remains on your sweat-soaked skin.With deliberate slowness, I pick up the razor-sharp instrument again, its sinister curves gleaming in the dim light. Your body is trembling, every muscle is tense with fear, while the man is preparing to inflict even more torment on you.In the flickering shadows, a grotesque smile appears on his painted face, a silent promise of future torment.

• Suddenly, the blade hits the blood-soaked concrete with a ringing thud and bounces off somewhere to the dark wall. Art goes back to his "magic" bag and takes out some kind of leather strap. With a deft movement of his hands, he hooks the clips connected by a strap onto your wet cheeks, the gloves wet with blood rub unpleasantly against your face. Art smiles his creepy smile and gently touches your chin with his fingers. Your eyes were swollen and your cheeks were wet from tears and saliva flowing from your open mouth. But not that you can complain here. All you had to do was mumble something, barely moving your limp tongue.

• An unpleasant crunch filled the half-empty concrete room. With a strong crack, Art broke off a piece of your tooth with pliers, the fragment unpleasantly scratched the already bleeding gum. All you had to do was mumble something indistinctly, to which Art just grinned madly and jokingly grabbed your tongue with the edges of the pliers, watching the despair in your eyes. He broke off tooth after tooth until a dozen teeth had been pulled out in his hand.

• Your throat burned from screaming, and your eyes burned unpleasantly from the tears you shed. You wanted it to be over as soon as possible. Realizing that Art won't get the right reaction from you anymore, noticing your exhaustion, he snorts soundlessly, clearly losing interest. With a graceful movement of his hand, Art deftly takes out an old battered pistol from a trash bag. He slides the edges of the gun over your cheek, drawing uncomplicated patterns. His movements are slow and upward. One. Two. Three. Finally, his hand reaches your head, the muzzle of the gun is pressed against your painfully throbbing temple. You wearily close your eyes, feeling a leaden heaviness in your limbs. His arms and legs were already blue from lack of blood.

• Art blows on the smoke coming from the shower of the gun and throws the weapon back into the bag. The man steps back, admiring his work and your smoking wound on his temple for a couple of moments. After that, he carefully removes the straps from the dead body and puts them in a bag, slowly leaving the building.

• Art pinned a young man to the ground, slowly cutting the meat from his face and putting the skin in his mouth. A soft laugh was heard abruptly behind him, and another pair of hands, softer and softer palms, covered his hands. The man raises his eyebrows questioningly and turns back, meeting your satisfied gaze. Your face still looked tired and tear-stained, and there were bruises and streaks of blood on your neck, but overall you looked almost.. normal?

• Without thinking twice, you grab the scalpel from his hand and with a sharp movement stick the blade into the clown's eye. He screams soundlessly, raising his hands to his face. You step back, watching his agony with a satisfied expression on your face. "You didn't think it would end so easily, did you?" You purred, folding your arms over your chest. The clown frowns, baring his sharp black teeth, and jumps up from the lifeless body. He walks towards you with quick steps and grabs your throat with his cold hands, lifting you off the ground. No matter how thin he looks, the guy has plenty of strength. You giggle, covering his hands with yours. You can already feel the air leaving your lungs, being replaced by an unpleasant burning sensation. Without thinking twice, you reach out your hands, touching the clown's face with your fingers, and scratch his painted face, mixing the paint with the blood from his wounded eye. He presses harder, enjoying the crunch of your airways.

• It quickly turned into a constant game of cat and mouse. Wherever Art was, you were always there. And I was in his way. Art was angry, cursed, and killed you. But you were coming back. Each time, your body was still decorated with old scars, but the man added new ones. He realized that the old scars would disappear. He had to make new ones. It was as if he was celebrating his favorite, best victim in this way. He can't be uninterested in your natural stubbornness and immortality.

• Over time, the clown really begins to look forward to your recovery and return, despite the slight irritation that you cause in him. He feels it in the pleasant piercing of his fingers. His hands crave you, your body, his fingers want to touch your scars and leave new ones.

• Your constant presence in Art's life begins to gradually change his thinking and thoughts, your image has settled in his head like a damn poison.

• Your immortality and lack of fear make you a really worthy partner for Art, he realizes this on an unconscious level. There's something about you. Something that makes his blood boil in his head. He's falling in love with you. Yes, in his own way, but he falls in love. Despite your initial maniac-victim relationship, Art is starting to see you as almost an equal. This is surprising. He loves you in his own twisted way.

• Art and you are in a love-hate relationship, constantly joking and arguing with each other. Despite the constant quarrels, you are united by a deep connection and understanding, which becomes apparent in your communication. You both feel extremely comfortable in such a relationship in your own perverted way (this is especially damn noticeable in sex..)

• Art begins to crave your company and gets annoyed when you are not around. There's something nice about knowing that after a bloody murder, he can properly combine his anger and passion on you. Especially in your intimate moments. Playing with blood, strangulation and other elements of bdsm is an integral part of your pleasure. You are a perfect match for each other, you are feared by all the states in the district.

Roman's primary structure hangs from cables as it moves into the big clean room at NASA's Goddard Space Flight Center.

What Makes the Clean Room So Clean?

When you picture NASA’s most important creations, you probably think of a satellite, telescope, or maybe a rover. But what about the room they’re made in? Believe it or not, the room itself where these instruments are put together—a clean room—is pretty special. 

A clean room is a space that protects technology from contamination. This is especially important when sending very sensitive items into space that even small particles could interfere with.

There are two main categories of contamination that we have to keep away from our instruments. The first is particulate contamination, like dust. The second is molecular contamination, which is more like oil or grease. Both types affect a telescope’s image quality, as well as the time it takes to capture imagery. Having too many particles on our instruments is like looking through a dirty window. A clean room makes for clean science!

Two technicians clean the floor of Goddard’s big clean room.

Our Goddard Space Flight Center in Greenbelt, Maryland has the largest clean room of its kind in the world. It’s as tall as an eight-story building and as wide as two basketball courts.

Goddard’s clean room has fewer than 3,000 micron-size particles per cubic meter of air. If you lined up all those tiny particles, they’d be no longer than a sesame seed. If those particles were the size of 16-inch (0.4-meter) inflatable beach balls, we’d find only 3,000 spread throughout the whole body of Mount Everest!

A clean room technician observes a sample under a microscope.

The clean room keeps out particles larger than five microns across, just seven percent of the width of an average human hair. It does this via special filters that remove around 99.97% of particles 0.3 microns and larger from incoming air. Six fans the size of school buses spin to keep air flowing and pressurize the room. Since the pressure inside is higher, the clean air keeps unclean air out when doors open.

A technician analyzes a sample under ultraviolet light.

In addition, anyone who enters must wear a “bunny suit” to keep their body particles away from the machinery. A bunny suit covers most of the person inside. Sometimes scientists have trouble recognizing each other while in the suits, but they do get to know each other’s mannerisms very well.

This illustration depicts the anatomy of a bunny suit, which covers clean room technicians from head to toe to protect sensitive technology.

The bunny suit is only the beginning: before putting it on, team members undergo a preparation routine involving a hairnet and an air shower. Fun fact – you’re not allowed to wear products like perfume, lotion, or deodorant. Even odors can transfer easily!

Six of Goddard’s clean room technicians (left to right: Daniel DaCosta, Jill Bender, Anne Martino, Leon Bailey, Frank D’Annunzio, and Josh Thomas).

It takes a lot of specialists to run Goddard’s clean room. There are 10 people on the Contamination Control Technician Team, 30 people on the Clean Room Engineering Team to cover all Goddard missions, and another 10 people on the Facilities Team to monitor the clean room itself. They check on its temperature, humidity, and particle counts.

A technician rinses critical hardware with isopropyl alcohol and separates the particulate and isopropyl alcohol to leave the particles on a membrane for microscopic analysis.

Besides the standard mopping and vacuuming, the team uses tools such as isopropyl alcohol, acetone, wipes, swabs, white light, and ultraviolet light. Plus, they have a particle monitor that uses a laser to measure air particle count and size.

The team keeping the clean room spotless plays an integral role in the success of NASA’s missions. So, the next time you have to clean your bedroom, consider yourself lucky that the stakes aren’t so high!

A/N: I alternate "verses" (main story arc chapters) with "leitmotifs" (critical flashback chapters with contextual adventures). It's a play on One Piece's own style and a way to keep things fresh.

I do not curate tag lists, but I do reply to comments when the next chapter goes live!

You caught yourself smiling.

Your father’s guitar, whole and undamaged if entirely out of tune, sat before you. Tracing worn patches of varnish where his arm rested, where his thumb wore down the finish along the back of the neck, you felt right. Whole. Purpose swelled in your little girl heart, growing it back into the right shape as you plucked, listened, tuned.

The men around you didn’t matter anymore.

It wouldn’t be the first time you’d played for pirates, even if it was the first time performing on an actual pirate ship. Plenty of crews moved through the bars and taverns where your father worked, where you practiced and practiced and practiced until your voice and your playing flowed into his as easily as two shadows joining together.

You once imagined you sang for two in your mother’s absence. Your father insisted you had her voice. But after…

Well, now you sang alone – when you sang at all. It was like the part of her you’d carried for so long twined with your father when they were reunited, and their song was so heavy with love it sank to the bottom. Alone, you were entirely yourself. You had her voice and his songs, but they belonged to you, not you to them. It might be liberating if it wasn’t so lonely.

But you were brave, and you had your things back, and you would prove yourself to this dangerous crew.

Then you’d figure out how to escape.

You glanced up from your work and spied the red-headed boy smiling at you. He must’ve caught your lapse in focus. Tucking the corners of your frown firmly in place, you returned to what mattered.

Once the strings answered with the right notes, you adjusted your seat on the deck, propping the instrument at an angle over your knee as you thought of what to play. Pirates loved a shanty, something to sing along to, but you weren’t playing in a pub and angling for tips. They only returned the guitar so you could prove yourself. A shanty wouldn’t dazzle, enchant, stun.

Winning their respect – at least for your craft – meant breaking something. A heart. A mind. A fundamental understanding of who and what you were.

You needed to make an impression, and it needed to be twice as powerful since you’d lost any chance to impress them the first time round.

Without announcement or preamble, you began.

Pirates fell quiet in waves, the ring growing wider and wider with every note until only the wind, the sea, and the ship’s groans accompanied you.  

You swam through the music, giving yourself over to tides that obeyed your touch, surrendering to your greatest strength. The guitar sang, and a wordless story bloomed. The melody gave listeners space to feel, guiding them along different paths that all answered to the same thrill. It was lovelorn longing. A voyage through changeable seas. Rage, hope, and passion.

“Music is magic,” your father used to tell you, guiding your touch over his guitar’s frets. “You become a god, conjuring new worlds in your audience’s hearts and minds.”

Threads of harmony stretched between notes, and you gathered them, folding them into the melody, twisting everything into a single yarn, carefully measured. And cut –

.. just so.

The final refrain hung in the air, and as the strings trembled still under your fingertips, you felt the song lingering, saturating your corner of the world. It ran between the boards, seeping into the wood’s grain, and the sails’ weave trapped more than wind.

Reality settled back on your shoulders, pushing your soul back into your body. The pirates around you stirred, and you peeked up at the captain. His reaction mattered most.

A great smile curled behind his mustache, but you didn’t recognize the expression in his eyes. Too fierce to be entirely kind, but too proud to be displeased. It was like he’d split his face into two different feelings, or his mask had slipped to reveal more than he intended.

“I can see why you’re going to Dressrosa,” he said. His big, warm voice broke some spell on his crew, and a round of gruff affirmations echoed the captain’s sentiment. He leaned forward, elbows on his knees, to get a little closer to your level. “And you’re going all by yourself? Someone waiting for you there?”

“I don’t need anyone else.” You snapped your attention to your guitar, beginning the post-performance maintenance rituals. The scabs on your hands had all torn open, and you folded a corner of your sleeve to delicately buff the blood off the wood. It wasn’t the first time practice left you bleeding, but it had been a long time, and the dawning sting made your nose burn. You refused to cry in front of pirates. “I’m brave enough by myself.”

“No doubt.” He leaned back, and his second leaned in to murmur something that had his captain nodding.

You had your hands full, though. Really, to get the guitar clean, you’d need a better cloth and some vinegar. Your shirt wasn’t enough to get the blood out of the strings.

Before you could work up the gumption to ask, a pair of hands caught yours and yanked them away from your task.

“You’re hurt!”

The red-head again.

You pulled, but he didn’t let go. His face was pure determination, bent brows and all, and he called for Crocus, the doctor, who stomped over with purely medicinal frustration. He seized your hands from the boy, twisting them back and forth to see the damage, grumbling all the while.

“No more playing that thing until these heal over,” he ordered. Sensing your rising defiance, he added, “If you don’t take time to heal, you could lose sensitivity, and that will impact your playing. Do you want that?”

Mournfully, you shook your head, and – still holding your wrists – Crocus pulled you to your feet and marched towards the lower decks.

“Time to rebandage these.”

---------------

“Are you asleep?”

You grit your teeth and held your breath. Deep in the belly of the ship, it’s endless creaking had almost lulled you to rest, but the voice jarred you back, and you felt every bruise and cut wake with you.

You’d been sentenced to sleep with the apprentices, the captain pointing out that they’d found you, and now that the doctor – Crocus – had released you from the infirmary, you were the two boys’ responsibility. The boys shared a narrow bunk room, and Gaban brought a spare mattress that smelled more like salt and tobacco than straw or feathers. You’d arranged it on the floor, plopped down, and immediately closed your eyes.

After about an hour of bickering, the boy with the blue hair and red nose fell asleep.

Unfortunately, the red-head did not.

Fake snoring always sounded fake, and sleeping people didn’t answer questions, so going still and silent was your best bet. With luck, the boy would get bored and try falling asleep himself.

He was on the lower bunk, and closer than you liked. You heard him shift, and eyes stabbed into the back of your head.

“You’re a bad faker.”

Rolling over, you met his grin with a scowl. “What do you want?”

“We never introduced ourselves.” He held out his hand. “I’m -”

“A pirate. A stranger. I’m going to get off this ship and never see any of you ever again, so we don’t need to know each other’s names.”

He shrugged, pulling his hand back just to prop himself up on his elbows.

“Why are you so set on that fancy music school?”

He wouldn’t shut-up until he asked his questions, and you resigned yourself to some kind of conversation. Sitting up, you pulled the blanket around your shoulders and raised your chin. You weren’t sure what you were defying exactly, but you wouldn’t be coaxed into any kind of cooperation, especially now that you had your things back. Your mother’s necklace hung secure around your neck, and your father’s guitar sat between you and the wall, within reach.

“I don’t have to tell you anything.”

“I’m just curious.” He sounded genuine, and as he rested his chin on his fists, looking like any other kid you’d met on any other ship, your determination wavered. “I mean, you have the whole world, but you want to go there. Even now, with your hands bleeding and your arm hurt, and, and –” Little gestures ate up the space between words. “It must be something special.”

Warm lantern light seeped through the rough curtain, spilled under the hum. It caught in his hair and warmed his eyes. He glowed, a beacon in the dark, and you wondered if that made him a lighthouse or a trickster spirit luring you into trouble.

You chewed your lip. Everything felt heavy. And you’d never gone so long without really talking to someone before. The things you wanted to say and feel got bottled up until the pressure hurt your head.

The red-head wasn’t a grown-up, even if he was a pirate. His meanness must be smaller, just to fit inside. Or maybe pirates’ hearts didn’t go stale and sour until they got bigger.

If you said just a little, talked to a real person like he was just a person, maybe you’d feel a tiny bit better.

You scooted to the edge of his bunk, and he leaned in until your foreheads nearly touched.

“My dad always said we’d go,” you whispered. “He said we’d need to go somewhere new after he found mom again. And he said only the best teachers in the world could keep up with me, so we’d go there.”

The memory brought you no comfort. It used to make you so excited. Now, it was the only direction you had left to go, and this wasn’t how you were supposed to get there at all. The seed of a dream had a broken shell, and it threatened to cut you when you handled it.

“Find your mom?”

Oh.

The warmth you’d been reaching for vanished. It didn’t fade. It just blinked out. A snuffed candle.

He didn’t mean to be a bully, you could tell, but the promise of that word – mom – pierced deep. It was a memory now, and not a future. The story hadn’t finished the right way, and everything was upside-down and awful. No doctor could fix the break left by the end of your whole world.

Your eyes overflowed. Then your nose.

You wriggled back, flopped down facing the wall, and pulled the blanket to cover your head. “I don’t wanna talk about it.”

The quiver in your voice didn’t sound very brave at all.

But, at last, the room went quiet.

---------

When you finally fell asleep, you sank deep. If your nightmares woke you, you didn’t remember, but you tasted the gunpowder on the wind as you watched the ship carrying your parents sank.

A big, gentle hand on your shoulder, shaking you awake gradually drew you back to the surface, and you struggled to unspool memory from dreams that clung to reality like cobwebs. Blinking, dazed, you tried to recall when you’d come aboard a ship, what day or time it was, and why your father had left his guitar…

You rubbed your eyes, yawning.

“Wake up now. We’re putting you ashore.”

Silvers Rayleigh, the Dark King, crouched beside you, and the past few days hit you like canon ball. Physically jerking away, you slipped out from under his hand, but your back was to the wall, and he took up a lot of space.

He chuckled.

“Good morning to you, too, troublemaker.” Settling down to sit cross-legged in the narrow bunk room, he dropped a rucksack in your lap. “The crew who kidnapped you didn’t keep any of their victim’s personal items, I’m afraid, but this should get you started.”

Tugging it open, you peered inside like a snake would jump out and bite you. But nothing terrible happened, and the pirate let you investigate in peace, watching you steadily, waiting for something.

A shirt and trousers – doubtless stolen from one of the boys judging from their size – sat at the bottom, cushioning a water flask and a wax paper bundle you assumed held food. A drawstring pouch sat innocuously in the middle, and you reached for it with dread.

Your eyes popped wide at the Berries inside.

You immediately pushed everything back at Rayleigh. “I can’t take this.”

“Why not?” he asked like he already knew, like he’d planned for this conversation.

“Because it’s pirate loot,” you said, “and I’m not a pirate. And pirates don’t just give money away.”

“Technically it’s your share of the treasure you helped find,” he said, pushing on as your face went stony. “But you can think of it as your performance fee.”

Your eyes dipped to the bag. Fees and tips made sense. You knew how much your father made, how he balanced the potential for tips against the (usually low) guaranteed pay from a tavern keeper. He taught you sums with the change you collected during shows.

He’d never made so much, not even in a month. Maybe not a whole year.

“This is too much.”

A smirk that wanted to be a smile quirked over the pirate’s face. “For your talents? Not at all. Know your worth, kid.”

Your lower lip slipped between your teeth, and you chewed relentlessly as you considered. Turning away money was stupid – unless there was an unspoken cost or secondary service required. If you asked, he could lie.

And you needed the Berries. Your kidnappers really had thrown out anything they couldn’t sell, and they’d taken all the coin your father left. Without this payment, you may never even reach Dressrosa, let alone find a place to stay and eat while you looked for work…

You pulled back the rucksack. It fit nicely in your arms.

“Good. Glad we can agree on that. Now, there’s something I wanted to discuss with you before you leave.”

Oh no. There were strings attached.

He pointed at you, right between your eyes, like he could see inside your head.

“You have haki. Rare haki. There’s no time to teach you, but look it up when you’re older.” He looked entirely serious, and you sensed this was one of those adult talks you were supposed to obey even if you didn’t understand. “Try to keep a reign on your emotions. Don’t try intimidating people until you have some control, or someone will find a reason to control you. Got it?”

A warning. Not about pirates or marines or anyone specific. Just people. And you already knew people could be cruel, no matter what they called themselves. You wouldn’t be used again. You refused to be controlled.

So, you listened.

“I’ve got it.”

He let the smile have its way with his face and ruffled your sleep-mussed hair. As you swatted his hand away, he said, “You’re going to be a terror when you grow up. Hope to see your name in the papers some day.”

“I haven’t told you my name.”

“That’s why I look forward to reading it.” He slapped his knees and stood up. “Grab your things. We’re sending a tender to shore. It’s a pretty safe little island with lots of shipping traffic, so I’m sure you’ll get where you’re headed. Time to head out.”

You followed him on deck, finger-coming your hair as you went. A few crew members waited by the rail, where a rope ladder hung down to a small boat. Gaban sat at the oars.

“Why can’t we go?” Of course, the red-head was there, and he was whining to his captain, wheedling for more opportunities to make himself a menace. “It’s just to shore and back, right?”

“The fewer pirates she’s seen with the better,” Roger said, patting the boy’s head.

It looked too familiar, and you side-eyed Rayleigh, daring him to change his mind and try to keep you aboard with their other little pets. He caught you. Scoffed, amused.

You must look even smaller than usual with the guitar case on your back. It was nearly as big as you were, and if any of the pirates changed their minds at this crucial moment, there was nothing you could do to stop them. Well. Maybe you could swim to shore…

The doctor flicked your forehead, claiming your attention. “Let yourself heal. Have a little patience. Hear me?”

A nod was enough of an answer for him, and he stepped back, clearing the way. You didn’t wait for further permission and booked it to the ladder.

“Safe travels!” Roger laughed behind you.

In another moment, you were in the boat, and your escort pushed off. The boat rocked with the waves rolling into the shallows, and you held tight, squinting at the land, wondering how far you’d need to walk to the nearest town.

“Hey!”

You snapped around to the boat. The red-head shouted from the rail, the only one still watching your escape.

“We’ll see each other again someday, okay?”

Not if you had anything to say about it. Rising to your knees to make sure he could see, you leaned out as far as you could and stuck out your tongue.

“Idiot!”

His smile didn’t dim a bit. “Look forward to catching up with you!”

Still waving, he laughed, leaving you with a prickling sense of connection you couldn’t shake as the boat drew further and further away, until he was just a red speck you left behind.
