Ventilation reduces the risk of COVID. So why are we still ignoring it?

Why indeed?

Over the last decade, global SUV ownership has doubled. If it keeps growing at its current rate, increased SUV ownership will offset the entire emissions reduction from electric vehicles. Plus they’re much more likely than smaller cars to kill pedestrians.

“In Canada, people can die with dignity. They should be able to live that way, too. “
A living benefit for those who are severely disabled should be the law of the land before we open up the #euthanasia gates further. #MAiD #cdnpoli https://www.theglobeandmail.com/opinion/editorials/article-in-canada-people-can-die-with-dignity-they-should-be-able-to-live-that/

Finally, the CDC is encouraging people to wear masks.

Never forget, a 13-year study of a dozen cities found that protected bike-lanes led to a drastic decline in fatalities for ALL ROAD USERS. And painted bike-lanes? No safety improvement at all. As for sharrows, it’s safer to NOT have them. Via #StreetsblogUSA, read their article linked below. #bikelanes #bikes #cities #transportation #mobility #sharrows #infrastructure #urbanism

Well those two pictures certainly sum up the difference in approaches between Shenzhen and Guangzhou🤨

"How today started @BCChildrensHosp
in the Pediatric Intensive Care Unit. The lack of leadership, outrage + transparency is deplorable. #PICU in crisis, #ER times brutal, surgeries cancelled + kids dying of the flu. #bcpoli #CodeOrange"

In 1925, Dr. Cecilia Payne completed her PhD thesis, described as “the most brilliant ever written in astronomy.” At a time when few #women entered academia, Payne discovered what the universe is made of. Her work began a revolution in astrophysics.

Dr. Payne-Gaposchkin became the 1st female professor & 1st female department chair at Harvard. Given most of us remember names like Darwin & Newton, we should also celebrate Payne. #science #space

Upper-room #UVGI (Ultraviolet Germicidal Irradiation) is the most #EnergyEfficiency method for reducing risk in crowded spaces with tall ceilings. /3

Higher ceilings reduce risk. Requiring a higher Clean Air Delivery Rate in places with high ceilings to achieve 6 air changes per hour doesn't make sense. To avoid this problem, the OSPE committee recommends capping ceiling height at 2.7m (9 feet) when calculating the volume of clean air to hit the 6 ACH target. /2

Ontario's engineering society has released core recommendations for safer indoor air.

They can be downloaded from https://ospe.on.ca/indoor-air-quality/ #COVIDisAirborne

Our main recommendation is to provide a minimum of six air changes per hour (ACH) through ventilation, filtration or ultraviolet germicidal irradiation systems. BUT! 6 ACH doesn't apply well to small spaces like vehicles and large spaces with high ceilings. /1

There were no high school robotics competitions when I was a kid— but we did have the state science fair and math league. I remember going to those competitions— the strange feeling of being at some other school like a parallel universe. The odd way schools feel on Saturdays and holidays.

One thing I knew before we got there was I’d probably be the only black girl, only black person period, the only girl. I’d spend time on the bus thinking up sassy responses for “where are you from?”

If walking costs you $1, we all pay $0.01. If biking costs you $1, we all pay $0.08. If bussing costs you $1, we all pay $1.50. If driving costs you $1, we all pay $9.20. Via @thediscourse study.

This isn’t just about choice. It’s about who pays for your choice.

Lion from the Ishtar Gate in #Babylon, one of King Nebuchadnezzar’s many urban renewal projects. Nebuchadnezzar was no slouch as a general either, defeating the combined armies of Egypt and what was left of the Assyrian empire in 605 BC, and sacking Jerusalem in 587 BC, which led to the Babylonian captivity. His empire only survived for 25 years after his death, ending when his successors were defeated by Cyrus the Great, the Persian founder of the Achaemenid dynasty.
