Deep UV-C radiation can clean air from microbes.


"Far-UVC light has proven highly effective in real-world settings at inactivating over 99% of airborne viruses in occupied spaces, as demonstrated by a Columbia University study, offering a practical and continuous disinfection solution that could surpass conventional ventilation systems in preventing airborne disease transmission. This technology, safe for human exposure, represents a significant advancement over traditional germicidal UVC methods, which require empty spaces to operate.

Deep ultraviolet radiation destroys viruses from the air. That thing can help to control pandemics. Authorities can use Deep UV-C light to destroy things, like viruses in houses and quarantine areas. The UV-C light gives a cheap and effective way to destroy micro-organisms from layers and air. That thing will help to keep organisms away from offices and other places. The UV-radiation is most effective against viruses that have no chance to protect their genomes outside the cell. 

The researchers can use deep UV-C radiation. Along with ultraviolet lasers to destroy microorganisms from all layers. And that thing can used to sterilize food. 

Because radiation kills bacteria and viruses that prevent things like food poisoning. The fact is that the UV-C dose must be high enough that it destroys bacteria and viruses. If the radiation dose is too low that thing makes the bacteria and virus population more resistant to the UV-C radiation.

In the Chernobyl nuclear disaster site, the animals created protection against cancer and radioactive radiation simple way. Radiation destroyed all animals that couldn't resist cancer. The high radiation level removed all individuals that couldn't resist cancer. And that left only animals that could resist cancer alive. That thing caused the situation that the cancer-resistant genomes enriched in the population. This means that animals can create resistance against cancer and radioactive fallout. 

When we think of virus populations. Too low a UV-C dose can cause a situation in which only viruses that can resist the UV radiation are left. That means that only those UV-C-resistant viruses are left to cause infections. 

The resistance against antibiotics forms in a similar way. Antibiotics destroy individuals who cannot resist it. And only the individuals that can resist antibiotics are left. This is the reason why researchers investigate ways to replace antibiotics in large-scale sterilization operations. If the antibiotic dose is too small the bacteria can create resistance against it. The problem is that the UV radiation dose acts the same way as antibiotics. If the dose is too small, the creature can turn resistant against it.

Antigravity will be the greatest thing. That we have ever created.

"Artistic depiction of a fictional anti-gravity vehicle" (Wikipedia, Anti-gravity) Sometimes, if the airships have the same lifting power as the weight of the airship.  It can act like some “antigravity system”. Those systems are based on lighter-than-air gas or hot air. The system can have a helium tank. And the hot-air section whose temperature can be adjusted using microwaves or particles that lasers warm. Those systems are faster to control than some gas flames. This makes it possible. To adjust the lifting power.  If a thing like a balloon has the same lifting power as its weight, the balloon can be lifted to a certain point and altitude. And the balloon stands at that point until something moves it. That kind of thing can make an impression. On the antigravity systems. Modern airships. Like Lockheed-Martin P-791 can look. Like a “UFO”. The system can use systems to move the craft. Or maybe those ion systems are used for plasma stealth systems, if those airships' mis...

The first test flight of X-59 QueSST

The X-59 QueSST (Quiet Supersonic Technology) demonstrator is the next generation of aircraft design. The QueSST technology means. The aircraft creates a gentler sonic boom. Because its wings are radically long and narrow delta wings, and its nose is also radically long, which makes the sonic pressure cone thinner. That technology makes the sonic boom quieter.  The QueSST technology in X-59 is a new and radical design. All of those systems are caricatures. And the final solutions might look far different than the prototypes. The QueSST technology is one of the things. That is planned to be used. It is used in military and civil applications. If that technology is successful. It can be used in manned and unmanned systems. But that requires more work.  The X-59 also uses fundamental technology. Where the pilot must not have windows. To see outside. The camera and other sensors replace traditional windows. And that can be useful in more advanced aircraft that operate at hypersoni...

The theory about paralleled universes

http://crisisofdemocracticstates.blogspot.fi/p/the-theory-about-paralleled-universes.html Kimmo Huosionmaa There is the quite unknown theory about paralleled universes. In this theory, there is not a single universe. Universes are like pearls in the pearl necklace, and there could be the connection between those universes. The connection to other universes would make possible the channel what is forming when the black hole would make the gravity tunnel to another universe. And in the paralleled universe theory, there could be millions of universes in the line, and this is also known as "Multiverse-theory". This theory was established when the galaxy-groups were noticed by astronomers. In that time were noticed that there are so-called super-groups of the galaxy, and those super-groups, where we're so much galaxy that galaxy involved stars made some cosmologists think that maybe there is also groups of universes in the emptiness. This kind of structures is so enormo...
