Well well. Mask bad again.
TORONTO -- A recent study from engineering researchers in Ontario has found that high-efficiency masks are up to six times better at filtering aerosols compared to more commonly used cloth and surgical masks.
Researchers at the University of Waterloo looked into how effective different types of masks are at filtering out aerosol particles, which are solid or liquid particles approximately 0.001 millimetres in diameter and suspended in the air. They published their findings in the journal Physics of Fluids on July 21.
The team put masks over a CPR mannequin that could simulate a person's breathing and exhale aerosol droplets, which were made using olive oil, and measured the amount of aerosols that would be built up in a large, unventilated room. The measurements were taken from two metres away, the Public Health Agency of Canada (PHAC)'s recommended distance for physical distancing.
The researchers found that R95 masks were able to filter out 60 per cent of exhaled aerosols, and KN95 masks could filter out 46 per cent.
On the other hand, cloth masks and surgical masks only filtered out 10 per cent and 12 per cent of exhaled aerosols, respectively.
"There is no question it is beneficial to wear any face covering, both for protection in close proximity and at a distance in a room," said lead author Serhiy Yarusevych in a press release. "However, there is a very serious difference in the effectiveness of different masks when it comes to controlling aerosols."











Sarah said: "They didn't know Afghanistan, a place that is like our primordial tales where parents are served a stew of their children, a place that not only has never been civilized but relishes barbarism, would fall that fast."
Okay, you pushed my button Sarah. Here doth ensue a rant:
Can we all stop pretending these people are stupid? They're not. They are the very smartest of the smart, and they are EATING OUR LUNCH.
This fall of Saigon II is not a mistake. Not a miscalculation. Not a screw-up. It is quite deliberate. Everyone involved, for the last 20 years, knew this would happen. The Afghans knew it, the Taliban knew it, NATO knew it. They fucking well knew.
I'm not going to pretend that I knew it, but as news reports stop being able to lie their way out of this fiasco, reports keep popping up of documents and officials in and out of government who called this right from the start. They knew.
So why the surprise now? Why turn Trump's orderly and gradual withdrawal into a rout with people falling off airplanes? Because now they can pin the disaster on the doddering old man in the White House who can't find the bathroom on his own. Perfect fall guy.
Deeper issue, why let it happen at all? Because what happens in Afghanistan is not important. They don't care. As long as their gravy train keeps running and those biscuit wheels keep sopping up all that beautiful wonderful gravy, they do not give a single shit about guys falling off the outside of C-17s trying to escape the Taliban. They don't care about the world-wide reputation of the United States. They don't care about soldiers dying for nothing. They don't care if inflation drives the whole middle class into poverty, destroys your savings and fucks over the whole nation for 20 years.
Those things are not important, okay? They don't care.
And how do we know this? We know because we've seen it before! Anybody out there old enough to remember John F. fucking Kennedy playing chicken with Nikita Khrushchev over the Cuban Missile Crisis? It was revealed in his memoirs that Khrushchev turned those ships around because he finally understood that Kennedy was insane. Kennedy wasn't paying any attention to Khrushchev, he was busy positioning himself to win the coming election.
It wasn't important to Kennedy what the Soviets did. It wasn't important if a war started. It wasn't even important if nukes were launched. He didn't care. It was only the next crooked election that mattered. All those Joint Chiefs of Staff guys and the whole Cabinet knew that, and they let him do it.
Okay? That's what this really is. We are the stupid, clueless idiots who go along and let them do it.
Here endeth the rant.
Update: Support for my thesis is showing up.
Yeah. We've seen them do this shit before. They're doing it all the time now.
You really think the US Border Patrol can't secure their southern border? They can! They've just been told not to. You really think the Portland cops can't stand up against Antifa? They can! They've just been told not to.
You really think it's an accident that the USA abandoned Bagram air-force base with its fortifications and multiple landing strips because they couldn't stand up to the toothless hillbillies called the Taliban? You really think that the US military would -choose- to stage out of the single landing strip of Kabul airport? No way. This is an arrangement.
Whoever is pulling Biden's strings ordered this. I assume because they have to. I must assume this is because they're all guilty of things that will earn them the death penalty, and have nothing to lose. I think the big movers and shakers in DemocRat Washington have been doing shit that if we all knew about it, there'd be no crack deep enough for them to hide in. Pizzagate, if true, would be the least of it.
