Are PTFE oil seals suitable for old machines?

In modern industry, oil seals, as key sealing components, play a vital role in ensuring the normal operation of mechanical equipment and extending its service life. With the continuous advancement of technology, new oil seal materials such as PTFE (polytetrafluoroethylene) oil seals are gradually replacing traditional rubber oil seals due to their excellent performance and becoming the first…

"As solar panels heat up beyond 25°C, their efficiency decreases markedly. Green roofs moderate rooftop temperatures. So we wanted to find out: could green roofs help with the problem of heat reducing the output of solar panels?

Our research compared a “biosolar” green roof — one that combines a solar system with a green roof — and a comparable conventional roof with an equivalent solar system. We measured the impacts on biodiversity and solar output, as well as how the plants coped with having panels installed above them.

The green roof supported much more biodiversity, as one might expect. By reducing average maximum temperatures by about 8°C, it increased solar generation by as much as 107% during peak periods. And while some plant species outperformed others, the vegetation flourished.

These results show we don’t have to choose between a green roof or a solar roof: we can combine the two and reap double the rewards...

How did the panels affect the plants?

In the open areas, we observed minimal changes in the vegetation cover over the study period compared to the initial planted community.

Plant growth was fastest and healthiest in the areas immediately around the solar panels. Several species doubled in coverage. We selected fast-growing vegetation for this section to achieve full coverage of the green roof beds as soon as possible.

The vegetation changed the most in the areas directly below and surrounding the solar panels. The Baby Sun Rose, Aptenia cordifolia, emerged as the dominant plant. It occupied most of the space beneath and surrounding the solar panels, despite having been planted in relatively low densities.

This was surprising: it was not expected the plants would prefer the shaded areas under the panels to the open areas. This shows that shading by solar panels will not prevent the growth of full and healthy roof gardens.

What were the biodiversity impacts?

We used environmental DNA (eDNA) surveys to compare biodiversity on the green roof and conventional roof. Water run-off samples were collected from both roofs and processed on site using portable citizen scientist eDNA sampling equipment to detect traces of DNA shed by the species on the roof.

The eDNA surveys detected a diverse range of species. These included some species (such as algae and fungi) that are not easily detected using other survey methods. The results confirmed the presence of bird species recorded by the cameras but also showed other visiting bird species went undetected by the cameras.

Overall, the green roof supported four times as many species of birds, over seven times as many arthropods such as insects, spiders and millipedes, and twice as many snail and slug species as the conventional roof. There was many times the diversity of microorganisms such as algae and fungi.

Encouragingly, the green roof attracted species unexpected in the city. They included blue-banded bees (Amegilla cingulata) and metallic shield bugs (Scutiphora pedicellata).

How did the green roof alter temperatures?

The green roof reduced surface temperatures by up to 9.63°C for the solar panels and 6.93°C for the roof surfaces. An 8°C reduction in average peak temperature on the green roof would result in substantial heating and cooling energy savings inside the building.

This lowering of temperatures increased the maximum output of the solar panels by 21-107%, depending on the month. Performance modelling indicates an extensive green roof in central Sydney can, on average, produce 4.5% more electricity at any given light level.

These results show we don’t have to choose between a green roof or a solar roof. We can combine them to take advantage of the many benefits of biosolar green roofs.

Biosolar roofs can help get cities to net zero

The next step is to design green roofs and their plantings specifically to enhance biodiversity. Green roofs and other green infrastructure may alter urban wildlife’s activities and could eventually attract non-urban species.

Our green roof also decreased stormwater runoff, removed a range of run-off pollutants and insulated the building from extremes of temperature. A relatively inexpensive system provides all of these services with moderate maintenance and, best of all, zero energy inputs.

Clearly, biosolar green roofs could make major contributions to net-zero cities. And all that’s needed is space that currently has no other use."

pohatus very important observations on who is available for body heat sharing via snuggling, cuddling et al

Lewa: yes, serial snuggler

Gali: yes, appreaciates it

Onua: yes, great hugs

Tahu: yes but you have to goad him into it, es. "will you man up and cuddle w me". the warmth is worth the annoyance

Kopaka: the flesh would be willing but the soul is so complicated about it. lay down back to back with him and pretend to sleep to make him slowly turn around and snuggle. WILL wake up early to destroy the evidence. the chill is worth the annoyance

Turaga Metru: only yield to 2-second-long cuddles if exhausted. if you pile all six on one another they will automatically snuggle together though

Toa Hagah: only with each other and still very professionally

Turaga Dume: no (the warmth is NOT worth it)

Takanuva: yes, serial snuggler no. 2

Jaller: yes but you have to sort of casually brute force him into it. will fall asleep five seconds into snuggle

Hahli: yes but a bit shy

Hewkii: yes, loves a hearty cuddle

Kongu: no (very formal)

Nuparu: no (very awkward)

Matoro: the soul appreciates the thought but the flesh needs space. if you tell him youre available for snuggles he will keep it in mind and come to you when hes in need. very pleasant chill

Hafu: yes, especially if youre warm

Tamaru: yes, curls up nicely on your chest

Taipu: yes, splays himself like a corpse

Macku: yes but prefers Hewkii. fair

Kapura: yes. hes a perfectly still hot water bottle. delightful.

Kopeke: no (leave him be)

Krahka: yes, surprisingly

Pewku: yes and its good for your mental health

Jaller's crab: no (rocket launcher)

chreon christmas..... but,

chris rushing to leon's side.

against the tree, limp in the snow and under the cover of a grand evergreen, leon's head hangs lazily to the side.

chris drops to his knees, immediately moving any and all possibilities at once - fingers against leon's wrist, a palm gentle on his frosted cheek, a demand barked through a tense jaw and shivering lungs.

chris feels the trapdoor in his sternum open, his organs falling into the pit of despair - leon's cold skin, there's no pulse.

chris refuses to accept it. no, no matter what, he's saving leon. he's... bringing him home.

and leon shifts. his eyes flutter open, weakly. he's moving in slow motion as he rolls his head towards chris. a small smile.

chris is over the moon. and terrified. leon's clearly suffering from hypothermia, if not any other injuries hidden under his winter tactical gear. but he's conscious, he's alive.

leon seems a bit confused, and chris marks that down as he's already scooping leon up to take him somewhere to recover.

but before chris gets a proper grip, leon turns his head above to the branches of the snow cover, and then back to chris.

"guess you've been a good boy, redfield," and he chuckles with a smirk, "ol' saint nick got you a good present this year, huh?"

and before chris can snort a quip of his own,

"shame. no mistletoe," leon's voice gets quieter and he's limp again in chris' arms.

So I love the snow (pretty! I get to wear layers! soup time!) but I'm also like 'holy shit no wonder people built houses with the walls a mile thick, I too would sleep as close to the stove as I could without catching on fire if I didn't have HVAC, I have the modern luxury of a heated blanket and it still takes me a solid 15 minutes to get the bed warm enough that I stop shivering after I remove my house shoes to get into it.'

uh oh we're going into single digit degree days :(

why is it this cold?!?!? I'm in a tropical countryyyy Like yes yes thermal floors and mountain ranges but aaahhhhh it feels like winter and those don't even exist hereeeeeeee

"im the thing wearing sweatpants in summer"

"and im over here secretly calling myself after my fav sweater"

love that for you <3

i'm also curious what your fav sweater is but idk if that'd be like too much info to put out on the internet

i've skinned myself for you anon. behold, the Sweater

it is grey

and here is an accurate illustration of me in summer, wearing a downy fluff over my favorite sweater

I'm very skeptical of live action adaptations of anime, but it's looking good for One Piece? It seems like the mangaka has been very involved and enthusiastic about the project.

Ok if the mangaka has been involved then that’s like…. We’re not getting another death note level live action probably dkkdkdkfkfkf
