Common complaint from my laparoscopic patients. C02 gets trapped above the liver and irritates the diaphragm which shares some nerves with the shoulder/arm. More common on the right because the liver is there to trap some of the excess gas. The pain usually goes away in 24-48 hours.

That's a no go my bud.
Make sure you bring this up and save their responses via email ☺️ to cover your ass.
A lot of people may say 'get OSHA involved' but make sure your untouchable because the most probable reality is the job will fire you over something completely unrelated as retaliation. Even tho retaliation is technically illegal there's so many loopholes HR will know about..

Interestingly, that's essentially the same stuff.
3D printers just use a specific formulation that cures better with specific lasers. But the final step for some 3D printed parts? Cure in a nail salon UV box.

Put the charcoal in a 5 gallon bucket. Put holes in the side, under the height of the charcoal, and on the bottom if the holes are small enough such that the charcoal doesn’t fall through. Find a fan on Amazon with the correct diameter to sit in the top. Boom. Filter.
Oh and make sure the bottom isn’t sitting flat on the floor if you put holes on the bottom. Put something underneath like some nuts/washers or books(off to the side)so there’s at least an inch under the bottom for air to flow.
You could also get an exhaust fan for like a grow room, with some dryer hose attached, and put the hose entrance right next to the printer, and the fan exhausting outside through a window, so you won’t need to filter your air to begin with.
Edit- dude shouldn’t need to do any of this, it’s his employer’s job. If it was just him and his printer, I’d recommend he does what I suggested above.^^

Scientifically, it's valid. But IRBs are less tolerant than ever when it comes to unnecessary harm to volunteers. And sham surgery usually means unnecessary harm to volunteers.

Well, if we're playing the fallacy game, you've just committed the fallacy of denying the antecedent.
It's true that intelligence doesn't necessarily guarantee the presence of memory, you'll be hard pressed to find a serious model that omits memory as an essential component of the ability to learn from experience and apply that knowledge in new situations.

Thank you! I am a short stay surgical nurse, and I have often explained to patients that the air that is blown up and their abdominal cavity will be absorbed by their body, but I did not know that they used to CO2 and this information will significantly help when I inform people have their body will process the gas that is used to blow up the abdominal cavity during laparoscopic surgery. Thankyou!!!

Semi-off topic, but funny timing: Wife just got home complaining the plant she worked at just had a huge activated charcoal spill while doing some routine maintenace and she had to help clean it up, haha.

Yup. Inoculation > incubation >candling > harvesting > first filtering > centrifuge filtering > sterile filtration > more sterile filtration > filling> packaging >shipping.

Fairly simple algorithms can as well, but we wouldn’t call them intelligent.

In certain eye surgeries, gas is used to fill the eye and one can't fly for 6 weeks afterwards depending on the gas used. The gas can expand, causing increased intraocular pressure, which can be painful and result in blindness.

We don't "know know" because the infections are so rare and the virus is so dangerous. This is not a virus where one would do human challenge tests.
We do know what a successful flu vaccine match looks like though, and in animal tests (like the one linked) it shows what we want to see.

Prediction of what goes into the yearly vaccine is about a year or more out from the flu season it gets administered in. To make the flu vaccine, the flu virus (or viruses, since the seasonal vaccine usually contains multiple strains) has to be cultured in millions of eggs, isolated, purified, combined, and turned into vaccine. It’s a very slow process.
This is one of the reasons that an mRNA vaccine for flu could be such a groundbreaker. The turnaround time is potentially much shorter.

Not much - but in a way, that’s a good thing!
The current vaccine is made for human flu variants. Avian H5N1 is currently pretty different from the circulating human variants that the vaccine targets. While this is why the human vaccine offers little protection against avian H5N1, it’s also why the likelihood of you catching avian H5N1 from a bird is relatively low.
The human flu viral variants have evolved to fit human cellular surface proteins, not bird ones, and the antibodies the vaccine generates are to the human viral variants. The avian flu variants have evolved to fit avian cellular surface proteins, which don’t look a lot like human ones.
As long as the avian virus is only fitting well to avian proteins, it will stay difficult for humans to catch it. Weirdly, if the human vaccine were to start offering us more protection - because the avian virus had evolved to start fitting human proteins better - we’d be in more trouble.
