A house sized asteroid, which usually spends most of its orbit out past Mars ( in the asteroid belt ), crossed Earth's orbit today, at closer separation than the moon. https://www.msn.com/en-ca/news/technology/newfound-house-sized-asteroid-2020-gh2-flies-past-earth-today/ar-BB12Gvdz?ocid=msedgntp And... Bmpbmp1975, DID NOT claim it was the end of the world. ( sorry Bmpbmp1975, I just couldn't resist )

It is quite a bit more complex than that but it would require a lengthier explanation. Simply put is that while adaptive (as well as innate) responses can clear infections, obviously. However, at the same time pathogens have mechanisms that can delay or evade responses. Viruses replicate intracellularly, so once they managed to get into cells, they can remain hidden until the cells produces viral particles. There are also various strategies that keep those particles hidden from the host for longer. Simply speaking, if there are only few particles around who are not slipping into cells yet the immune system can clear them. But it is essentially a race between how well the virus hides and replicates vs the immune system finding viruses and infected cells.

<rimshot> I'm in town all week, folks

Don't listen to Trump. She still goes by that...

Ok. Haven't touched this topic for a long time, I don't remember limits or unbounded number of items in the proof. edit: Checked, my book was printed in 1993, guess I'll have to read some to catch up.

We now need to add "It was the international Maritime Organisation's fault that we hit the iceberg, so I'm not paying my membership fee".

Can you provide the source so we have more context

I assume the proof continues? Probably it uses the observation that if the online algorithm uses less than 4/3 OPT bins it must maintain that ratio at all times. A proof can use that observation and, as per the image, use two sequences of items of sizes (1/2-a) and (1/2+a) 1/2>a>0.

What part of it is the problem? Do you know how to write a function? Do you know how to compare two values? Do you know how to write a loop? Do you know how to access the elements of an ArrayList? If you can answer "yes" to all the above, then you should be able to solve the problem If you don't want to help people, maybe don't post in the thread

Don't believe everything you read on tinternet, but you can believe the experts on this site; just ask the right questions.

Are there scientific publications related to God? No. So why to have create a religious section forum if there is no science?

Yes knowledge and belief are different. But What proof do we have, for that God does not exist? If we can't, can't we believe it?

What you need are antigenic elements, you cannot easily isolate them from people. Or rather it is far easier to propagate it, and then create an inactivated form rather than injecting humans samples which are hopefully inactive (but may also carry other nasty stuff). So much of it is surface removal, too. However, considering that cell are constantly pumping out virus particles, also into the bloodstream and there are mechanisms for cell-to-cell transmission, I doubt that any physical removal would really provide a net benefit. A lavage is mostly used for sampling (at least afaik, we use to obtain lung fluid samples not sure whether there are other medical reasons.).
