COVID Masks: Mechanistic View: Part 2: Fine Aerosol Emissions:

Masks may increase fine aerosol emissions from: 1) nebulization of large droplets into fine aerosols, or 2) friability of certain mask materials creating "aerosolized fomites."

Please share:

Here are the studies:

The question is whether facemasks are actually a source for viral aerosols by:

1) Masks get saturated by large "respiratory droplets" containing viral molecules. Air turbulence against trapped droplets may create aerosols that eventually diffuse around edges. Continued...

Trapped droplets potentially get pushed through the filter media of the mask, getting nebulized into aerosols.

Particles don't always stay in the mask:

Study: Ha'eri 1980

Title: The efficacy of standard surgical face masks: an investigation using "tracer particles"

Albumin tracer particles put inside a surgical mask were dispersed into the room by breathing.

Viral molecules can get airborne from air turbulence.

Study: Liu 2020
Title: Aerodynamic analysis of SARS-CoV-2 in two Wuhan hospitals.
SARS-2-COV sub-micrometer aerosols not tightly bound to surfaces, get airborne when PPE is taken off.

For over 200 years the Census has asked “What is your sex”. This year there will also be an *extra* question asking about gender identity. That’s great. Two questions about two different concepts - lots of useful information /1

One question about facts – the sex you were born.
One question about feelings – how people identity and live.
The extra question will give us our first accurate indication of the size of the trans community. A move welcomed by everyone /2

So what's the problem? It's that trans pressure groups such as Stonewall say it's not enough that trans people have their own gender identity question. They think trans people should be allowed to answer BOTH questions according to gender identity /3

They say it's simply too offensive and hurtful to ask trans person a factual question about sex they were registered at birth. So now an undefined number of people will be allowed to put the wrong answer to the sex question so we don’t hurt anyone's feelings /4

This has alarmed scientists who need accurate data on sex.
Last year 80 academics, including Professors from top universities, wrote to the ONS saying they mustn’t do this /5

⚠ The Texas electric system is facing an unprecedented power shortage situation due to the extreme winter weather impacting the entire state, including Houston & the region. Texans’ electricity consumption needs have far surpassed current power generation. #houwx #hounews 1/10

Early this morning, @ERCOT_ISO declared a statewide power generation shortfall emergency and asked electricity delivery companies to reduce load through controlled outages in an effort to bring the supply of and demand for electricity back into balance. #houwx #hounews 2/10

As CenterPoint Energy made preparations to follow @ERCOT_ISO's directive to reduce load, we were anticipating outages of 15 minutes to more than an hour. #houwx #hounews 3/10

This morning, conditions for power generation were, & continue to be, very serious; @ERCOT_ISO needs electric companies to reduce their load at a higher level & longer than they originally thought, which in turn is resulting in longer outages for customers. #houwx #hounews 4/10

Unfortunately, if you are a customer who is currently experiencing an outage, you should be prepared to be without power for at least the rest of the day. #houwx #hounews 5/10

I couldn’t be more disappointed in #JudasAndTheBlackMessiah. The truth of what happened is there. There are survivors. We deserve, after being lied about so much & for so long, a whole reckoning

I mean what would possess anyone to focus on ‘humanizing’ one of the informants/killers but saying nothing about our other martyr, #MarkClark

Why are we not even asking why the founder & head of the Peoria Chapter, #DefenseCaptainMarkClark had to be called in as security?

Why don’t we learn the breadth & brilliance of #ChairmanFredHampton’s strategy? Are we only supposed to learn, like Hoover said, we speak, we die?

I did love #MamaAkuaNjeri’s reading of her poem. That was beautiful. But also beautiful is all the ways the legacy continues in the work of #ChairmanFredHamptonJr

One in four hydropower project sites along the Himalayan Rivers are likely to face severe damage from earthquake-triggered landslides, according to a research. #UttarakhandDisaster #earthquake @nivedita_Him @yamunajiye @Upadhyay_Cavita @Indian_Rivers @hridayeshjoshi

The research was conducted by researchers from the University of Potsdam, Germany, who compiled damages to 41 hydropower projects after Nepal’s 2015 #earthquake, and used that data to estimate earthquake-triggered damages to projects in other parts of #Himalayas. @yamunajiye

The model developed by the research team took into account the combined effect of ground shaking (Peak Ground acceleration) & river steepness (Mχ) and was applied to projects in Indian, Nepalese and Bhutanese #Himalayas.
@yamunajiye @hridayeshjoshi @nivedita_Him @Upadhyay_Cavita

The findings indicate that more than 10% of Himalayan rivers may be unsuitable for hydropower infrastructure given high probabilities of high co-seismic damages and ~25% of Hydropower projects are located along these reaches. #UttarakhandDisaster
#earthquake

The study points to an urgent need to re-evaluate hydropower development in the Himalayas. The model used in the study would also help in making a more accurate assessment of risks at locations for potential hydropower plants. #UttarakhandDisaster

Mini thread on @deshaunwatson & #Texans
Because I’m reading far too much BS from national mouthpieces who want to protect the Texans and the #NFL

This idea that Watson is going about everything wrong & disrespectfully is straight BS. Let’s use common sense here /1

Many national pundits claim Watson is handling things wrong because he’s shut off communication with the Texans & allowed “his team” to leak out various items about his being disgruntled.
These same ppl say Watson should not use media but go to team & talk behind closed doors /2

That’s a very team and league serving position for these national mouths to have. Always about protecting their access to the teams and the league.
Here’s the reality. Why would you continue to have talks with someone who clearly doesn’t give a damn what you have to say? /3

Watson was nominated by his team to bring issues to ownership. One of the biggest issues was the divisiveness & mistrust created & caused by Jack Easterby. The team’s lack of direction & lack of strong leadership. Deshaun brought these issues & more to Cal McNair during season /4

Cal McNair even spoke publicly that Jack Easterby wasn’t a “football ops” guy. Understood his role was more administrative & that he wouldn’t be involved in the GM or coaching search. He told Watson that the QB would be involved in those searched. /5
