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?”

Hey,
So many great posts on Mastodon! Sometimes you want to come back to a thread to see what new replies have been added, or you want to read the link in the post later, …

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.

'Many students are telling the National Union for Students that they cannot afford to continue with their studies.

'They’re having to choose between feeding themselves and carrying on with their education', a union spokesperson said. 'Many can no longer afford to travel to placements and to their campuses, or they're holding down multiple jobs to make ends meet. Inevitably, it is the students from the poorest backgrounds who are being disproportionately affected.'

To all Mastodon-admins: seems like there's an attack on all instances by troll accounts. Servers get slow because of it.
They use thousands of subdomains of activitypub-troll.cf. My 'pull' queues skyrocketed.

I now blocked the domain activitypub-troll.cf and all is back to normal. Please check if you're hit too.

It seems many people haven’t encountered the Swiss Cheese Respiratory Pandemic Defense model.

Since #COVID, #RSV and #flu are spreading a lot, I figured I’d re-share it.

Are you using an app for Mastodon? Which one do you use?

What does that do for you? Why do you use it?

Please explain in non-techie language.

Thank you!

I was diagnosed with #HIV in 1998, when I was 30.
At the time, I did not expect to live to 50.
I’m 55 now.
HIV treatment works and it means I can’t pass it on - we call this #UequalsU.
HIV changed. Tell everyone.
