SERENA W/draws From AO22
Re: SERENA W/draws From AO221 micron virus particle, 80 micron pore size mask, equals respect and compassion? Follow the science. Re: SERENA W/draws From AO22Follow the science? Then I suggest you read the following abstract from a 2020-paper in Nature. And there is plenty more in REAL scientific papers. The COVID-19 pandemic triggered a surge in demand for facemasks to protect against disease transmission. In response to shortages, many public health authorities have recommended homemade masks as acceptable alternatives to surgical masks and N95 respirators. Although mask wearing is intended, in part, to protect others from exhaled, virus-containing particles, few studies have examined particle emission by mask-wearers into the surrounding air. Here, we measured outward emissions of micron-scale aerosol particles by healthy humans performing various expiratory activities while wearing different types of medical-grade or homemade masks. Both surgical masks and unvented KN95 respirators, even without fit-testing, reduce the outward particle emission rates by 90% and 74% on average during speaking and coughing, respectively, compared to wearing no mask, corroborating their effectiveness at reducing outward emission. These masks similarly decreased the outward particle emission of a coughing superemitter, who for unclear reasons emitted up to two orders of magnitude more expiratory particles via coughing than average. In contrast, shedding of non-expiratory micron-scale particulates from friable cellulosic fibers in homemade cotton-fabric masks confounded explicit determination of their efficacy at reducing expiratory particle emission. Audio analysis of the speech and coughing intensity confirmed that people speak more loudly, but do not cough more loudly, when wearing a mask. Further work is needed to establish the efficacy of cloth masks at blocking expiratory particles for speech and coughing at varied intensity and to assess whether virus-contaminated fabrics can generate aerosolized fomites, but the results strongly corroborate the efficacy of medical-grade masks and highlight the importance of regular washing of homemade masks.

The internet is full of valuable information. Too bad you got stuck on conspiracy-websites.

Re: SERENA W/draws From AO22"He made his own decisions, and everybody is free to take their own decisions, but then there are some consequences," Nadal, who won his first singles match since August on Thursday, told reporters in Melbourne. "Of course, I don't like the situation that is happening. In some way, I feel sorry for him. But at the same time, he knew the conditions since a lot of months ago, so he makes his own decision."
Re: SERENA W/draws From AO22Lol, some people are so easily fooled, and lack any sense of critical thinking. They see something fake news that fits their narrative and copy-paste it… Where is the jumper in the pic with the feds that he wears in the other pics? Where is the mask he wore on pic 1? Why is the definition (sharpness) of Novak different from that of the other people, and do you really believe he would wear a tennis-shirt at that time and place on a plane-trip? If you can’t see and smell the poor photoshop-job done here, then there is no hope for you anymore… "Never argue with an idiot - they take you down to their level and then beat you on experience" "Don't wrestle with a pig: you both get dirty, but the pig actually likes it" Re: SERENA W/draws From AO22Having said that, he should change his name into NoVax Joke-ovic "Never argue with an idiot - they take you down to their level and then beat you on experience" "Don't wrestle with a pig: you both get dirty, but the pig actually likes it" |
