Airborne transmission of COVID-19 carrier particles during exercise

物理学界这一开拓性的发现已经点燃科学研究的星星之火,而他们的这项研究发展为前沿科技,也不过是时间早晚的事罢了,就像100年前我们无法想象今天的激光和电脑芯片那样,美国物理学会候选会长劳拉?H?格林在接受《纽约时报》采访时表示。

The Great Recession had devastating effects across the U.S. and few places were as hard hit as Arizona. The state was booming on the strength of its tourism and real estate markets during the 2000s. Median home prices jumped 70% between 2003 and 2006—only Nevada had bigger gains—fueling more building and construction jobs. Monthly unemployment was at 3.5% through much of 2007. But then the bottom fell out. Home prices plummeted more than 50% from their peak and 6% Arizona properties received foreclosure filings in 2009. Unemployment stubbornly remained in double-figures for most of 2009 and 2010 and only Nevada lost a higher percentage of jobs over the last five years. Household incomes declined at the fastest rate in the country since 2008.

I was delighted to be contacted by the Aeronautics team about this exciting project, proposing to evaluate particle movement during exercise and its impact on risk of infection during exercise. This work is vital and should inform guidance on exercise precautions, so that we ensure that people remain physically active and do so in the safest way possible."

The experiments are conducted using fixed equipment (such as treadmills and exercise bikes) in a correctly matched airstream, under conditions which accurately simulate the relative motion through the air of an exercising person. The tests are being conducted with Dr Kevin Gouder's team in the Department’s 10 x 5 wind tunnel, the upper section of which allows the use of human subjects without any flow constraint. The co-leads on the project are Dr George Papadakis (the project's PI) and Professor Denis Doorly.
