Is it possible to create a map of China which shows where corona-viruses can be found naturally, then show where the CDC centers are and finally where Covid-19 first appeared to visualize how likely it is to have come from a lab or nature?

One explanation is a cytokine storm. It's also possible that some of the virus may slip past the blood brain barrier, with could result in a localized inflammatory response. Lack of oxygen is a possibility as well. We would need more details regarding "patients didn't show severe respiratory symptoms." I've heard stories of patients conversing and acting fine with their pulse ox falling into the 70's or 80's, which I don't really understand. I know people who require oxygen, and if their pulse ox falls under 90, they start struggling, and if it falls under 80, they're in severe distress.
>>
>>11890277
Do you have any examples of someone whose flesh turned to gold, because we have examples of SARS-CoV-2 attacking the nervous system. Obviously more information is needed, but we know it's a possibility because it has happened.

Why even get a PhD in anything? If you even get a job in academia it would be low level biology, math, English teaching at a community college as an adjunct and make 20k a year. Especially with the current climate of academia with political correctness and all that shit. Students can just up and decide something you did was racist and you deserve to be fired and boom! Spend possibly hundreds of thousands for school and wasted your 20s studying something you loved. You’ll be black listed and gone from academia forever. All I would want is a decent salary and work on something challenging relating to my field and eventual tenure.

When pressure is applied on the smaller end of
the frustum, the pressure from the larger end
can be found:
P_2 = (1/k^2) P_1

With P_2 being from the larger end and in
direct proportion to P_1.

>>11890240
What is your purpose for learning set theory? Are you just looking to have a working knowledge of it for mathematics or are you trying to learn set theory proper? If the first then just read the first chapter of Munkres Topology book. If the second then Enderton is best.

From what i understand, the lactase enzyme was evolved in adult humans when we began breeding livestock that produced milk and drinking this milk as a source of nutrition. It is strange for one species to drink the milk of another species i am sure, but milk would contain all the necessary nutrients for healthy growth of a calf for several weeks before it transitions to eating grass. The quantity of lactase found in humans decreases or is gone completely from the age of 5 onwards (indicating this is only to digest milk from breastfeeding). Is it safe for a non-lactose intolerant person to drink extremely high quantities, or even entirely live off of cows milk and for how long? Would it also be safe for a lactose intolerant person despite the symptoms they will experience?

The map also seems to ignore the prevalence of nomadic transsaharan cultures like the Fulani or the Tuareg, who have subsisted on meat and dairy products from their cow herds for many centuries, possibly millennia.
>>
>>11886698
I think all humans are capable of producing some lactase, and the amount excreted by the pancreas can be increased or decreased by how much lactose you consume. In other words, if you think you're lactose intolerant, starting with maybe a tablespoon of milk and slowly increasing the amount may eventually allow you to consume a glass of milk without issue. Or you can just consume fermented dairy, which is what many cultures chose to do. Unpasteurized dairy will ferment on its own.

Lately I have been experiencing certain symptoms that used to occur under particular circumstances But now have increased their frequency to broader circumstances.

It used to be that if I exercised after a few days of relative inactivity I would itch. My whole body would feel a prickly sensation that would subside after I worked up a sweat.

Now no matter how often I exercise I experience this whole body prickling sensation whenever I feel a warming in temperature. So for example I just took the trash out and the heat caused me to feel this sensation. It isn’t really painful but it is very uncomfortable.

This may be related to my mild to moderate psoriasis. I’m unsure though.
>>
I don't have psoriasis, but I also get that tingling sensation when working out after longer periods of inactivity. And rarely when active.

tl;dr: bump out of interest.

a political-economic trend that started in the 70s or earlier and replaced (or tries to replace) keynesianism, that promotes laissez-faire and a technocratic "economy over politics" view of the society (even though their proponents usually make retarded mistakes when they have the power of the state/government). it became really popular in the 80s/early 90s.
one of the policies that came with it was it was wholesale privatization of many public companies (public as in owned and managed by states/governments) for pennies, and the almost abandonment of public schools and universities.
some examples: in the country I live now we pay for "public" universities and some of its buildings are almost falling down. in another country where I used to live, professors would teach for the love of teaching, without getting paid a single cent. these countries export raw materials and tons of food to rich countries... and most people barely get any benefits from that.

I want to build a scale tank and add some weights into it to have it obtain not only scale dimensions, but accurate scale weight also. At first i thought i just scale the weight down but can’t have my 1:35 Tiger pressing 1428,5 kilograms. So how do i calculate it correctly?
>>
Weight/mass is proportional to volume, which is the cube of length, and a model scales down the length at the specified ratio.

So assuming your actual tiger tank was 50,000kg (35x1428.7kg as you’d specified in your post), the mass of your scale model should be 1.17kg approx.

>You’re missing the point of the subscription model which is to encourage participation in the circular economy, it’s not that products will break down after xx time but you’ll need to turn them back in and they’ll either be refurbished and sent out again or if there’s a substantial upgrade the parts will be fully recycled.

The free market, despite its advantage, has largely lost the opportunity to create events in the economy in favour of various financial instruments "which cannot fail". and which have NOTHING to do with the free market. Some bizarre tax havens, algorithms controlling the flow of finance. The free market HAS LOST ITS ABILITY TO CONTROL ITSELF.

Today's economic system is IN FACT more CENTRALLY CONTROLLED than it used to be, leaving aside of course former Soviet Union area. In a blanket every huge company is such a small state with typical central planning, so the bigger the monopoly in the economy, the more centrally controlled the market will be. However, this is not socialism, because profits are completely private. That's main difference.

Subscription items instead of cash - transfers and cards. Then a system of citizen evaluation like in fucking China.

That graph is highly misleading, aka lying.

It's comparing real incomes (which take inflation into account) with costs of services. The comparison is false, it's not needed because inflation is built in already into any real wage calculation.

Nominal wages have increased across the board. If you are going to list the variations of individual costs you should compare them with the variations of nominal wages.

If you are going to list variations of real wages, then the comparison with cost variations is not needed because those are already built in into said calculations.

For a board that hates us Economists so much, /sci/, like most normies, is surprisingly illiterate about it.
