i'm gonna need one of those fucking anticoagulant mushrooms bc i think a blood vessel is occluding in my brain.

[ask-a-vetblr]

I have trouble finding the pulse on patients (we work with dogs and cats). I know where it is located but it takes me 2 years to finally feel it. Do you have any tips?

vet-and-wild here.

I used to hate this answer but now I've realized how true it is: practice. Honestly, just practice with every animal you can and it'll start to become second nature. But there are some things that may either help or hurt (assuming we're talking about femoral pulses here):

-Good luck finding it when they're sitting/laying. Sometimes I can get it on a laying animal but it's always harder than if they're standing.

-Don't press to hard, you might be accidentally occluding the vessel.

-Overweight animals or little stubby legs can be tricky.

The best animals to practice on are large, fit, short haired dogs. If you want an easy target, that is. It's generally really easy to find on those kind of dogs and it can help you get comfortable with anatomy until it becomes easier to apply to smaller/sicker things.

“Vera Roe,” 21 (Germany 2006)

A case report published in Ultrastructural Pathology Volume issue 30 documented the death of a young mother after legal abortion.

Vera was 20 when she went in for the abortion that would end two lives. Even though she was going to given anesthesia, nobody ran the blood test that would have revealed critical information. Anyone about to undergo an election operation should first be assessed to make sure that they are healthy enough. She should have had a full pre-op examination with the necessary tests, but this didn’t happen.

Vera never woke up. Because of the lack of critical blood tests in advance, nobody diagnosed her sickle cell disease until she had already suffered a sickle cell crisis. She was comatose for the rest of her life and spent over a year on aggressive life support before dying of multiorgan failure and aspiration pneumonia.

Vera’s autopsy confirmed that she had sickle cell and showed the extent of the damage to her body. In addition to the sickle cell crisis and coma, she suffered multiple occluded blood vessels and severe necrosis of the brain.

Other cases of sickle cell patients killed by abortion include Betty Gail Hines, Barbara Riley, Margaret Davis, “Jenny Roe”, Sherika Mayo and “Adelle Roe”.

oh boy howdy does KSP function on some troll physics logic. no, like literally. docking ports have a slight magnetism to them to make alignment easier, but if you put two docking ports on the same vessel and point them at each other, it'll pull your vessel along with no external force.

it's fucking goofy

another fun bit is how KSP only loads structural physics (calculating joint strengths and stuff) within a radius of 2300m of the active vessel, measured from the root node, but it calculates collisions at much further distances. this means that you can build huge megastructures that should collapse under their own weight, but make them infinitely strong by just offsetting the root node away from the rest of the "vessel" by 2300m

my personal favorite category of exploits is drag occlusion - by using fairings, engine plates, and sneaky offsetting you can make craft that have literally zero air drag, and do goofy shit like orbit at an altitude of 500m with a craft that looks like a brick.

the only reason this works is because doing actual fluid dynamical simulations is pretty infeasible, so KSP cheats by calculating drag individually for each part, but considering some parts to be "occluded" so you don't get additional drag from stuff that's streamlined with the rest of the rocket or hidden inside cargo bays. this works reasonably well until you become aware of it and start optimizing for it.

tldr Kerbal is a clownshit game held together by popsicle sticks and chewing gum and you should absolutely play it

Kerbal Space Program was once afflicted by a bug the fans dubbed the "Deep Space Kraken", whereby if you travelled far enough from the origin of the game's coordinate system, floating point rounding errors would cause your spacecraft's components to become misaligned and/or clip into each other, resulting in the craft falling apart or exploding for no obvious reason.

The bug was later fixed by defining the active spacecraft itself as the origin of the game's coordinate system. In effect, the spacecraft no longer moves; instead, the spacecraft remains stationary and the entire universe moves around it. Owing to how relativity works, to the player this is indistinguishable from the spacecraft moving about within a fixed coordinate system, and it ensures that the body of the craft and its components will always be modelled with maximal precision.

While elegant, this solution introduced a new problem: it was now possible, by doing certain stupid tricks with relativistic velocities, to introduce floating point rounding errors to everything except the active spacecraft. In extreme cases, this could result in the destruction of the entire observable universe.

Some might call this one of those situations where the solution proves to be worse than the problem. I call it a perfect expression of what Kerbal Space Program is truly about.

Proliferative sickle cell retinopathy

Proliferative sickle cell retinopathy (PSCR) is characterized by several distinct retinal features. Sea-fan neovascularization represents abnormal new blood vessel growth in the peripheral retina. Peripheral ischemia, caused by occluded blood vessels, leads to areas of retinal non-perfusion. Black-sunburst lesions are hyperpigmented areas resulting from previous hemorrhages and pigment migration.…

I went looking for a particular illustration of how these work that I'd seen elsewhere online, but couldn't find a version that was attributed. The illustration style was something I was sure I'd seen somewhere, so I checked and found it — these are from the journal Experimental Musical Instruments, Vol. 14 #1 (September 1998), in an article written and illustrated by artist and musician Brian Ransom:

The top image shows how your basic "whistle" version works; the changing position of the water in the chambers forces air out through the whistle mouth. The second image (seen less often online) is how the more warbling, bird-like sounds are made. The air intake in the first chamber is more occluded, so a vacuum is formed that pulls bubbles back through the connecting channel, interrupting the flow and producing the wavering sound.

According to the article, the vessels have been found from southern Peru to Mexico, and were made as early as 1200 BCE; production stopped pretty abruptly with European contact, so it's likely they served a spiritual/religious purpose as well as an artistic one, and that got stamped out with the conquest.

(I'm seeing some stuff online, mostly in woo-woo pieces about these things' healing properties, about how these were just considered weird water jars by archeologists until 1972, when some white author figured out they whistled; since the article by Ransom doesn't mention him, mentions his own experiences in 1978, and cites a 1951 book, Instrumentes musicales del Peru (Musical Instruments of Peru), I'm leaning towards considering that self-aggrandizement at best.)

(EMI was edited and published by Bart Hopkin, author of Musical Instrument Design, between 1985 and 1999; all 72 issues are up on the Internet Archive. It's primarily about non-electronic instruments, but does have scattered articles on electrical amplification and circuit bending.)
