A short thread on how face masks work, why we wear masks *to protect other people from ourselves* and not the other way around, & why wearing face-shields without a mask, masks with valves, or masks that hang open on the bottom or sides IS ACTUALLY DANGEROUS FOR EVERYONE ELSE...

 I am going to start off by citing from a great paper by @trishgreenhalgh about the benefits of mask wearing, which you can read in full here: https://t.co/l0NfuU85cZ
Masks can work in 2 ways: protecting the wearer, & protecting other people from exhalations emitted by the wearer. Surgical grade masks are supposed to do both. They block out small particles emitted by the source, AND they filter those particles out from other emissions
For cloth masks, however, they are not so good at filtering out tiny particles which can contain viruses. But what they are good at doing is limiting the large droplets people give off when they breathe or cough – before they become aerosolised.
This means when you wear a cloth mask, the most important role that it plays is not protecting you from other people's exhalations but *protecting them from yours*. @trishgreenhalgh calls this 'source control' i.e. 'protects other people from droplets emitted by the wearer'
Unfortunately most people seem to think they are wearing a mask to protect *themselves* from everyone else. Which, unless you are wearing a fancy medical mask with a fancy rating, is not only selfish but also incorrect.
What cloth masks are supposed to do is filter the air you breath out, right at the source. This blocks large droplets as they are emitted, before they can become smaller aerosols (which are harder to block & can more easily make their way through another person's cloth mask)
Early on, when people were (mentally) struggling to breath with a mask on, lots of people bought & sold masks with vents. This meant what the wearer breathed in was filtered, but what they breathed out (via the vent) was not. So, no source control.
The same goes for these terrible 'half face shields' now on sale, that cover the nose & lower part of the face with clear plastic but are *open at the bottom*. This actually means both inhalations AND exhalations are not filtered by anything. You might as well not wear anything.
the same applies if you have a mask – even a medical grade one – that does not fit or is not properly tied, and has gaping holes under the chin, above the cheeks, or on the side of the face. If there are gaps where air can get in or out, your mask is pointless and even dangerous.
Masks made using only one layer of fabric – like buffs – are also not great at doing anything except making it look like you are wearing a face cover. Which is why most medical centres etc won't accept them. They are ok-ish for exercising outdoors, and can be worn by kids.
Face shields by the way have similar flaws *as masks* (which they are not, which is why they *must be worn together with a mask* and are not sufficient on their own). Shields are barriers not filters, and may protect the eyes, eg.
Bottom line:
The reason you wear a mask because *you* could be a source of SARS-CoV-2.
If you wear masks that allow your breath to leave unfiltered by layers of cloth, you may as well not even wear one.
Please, for all of our health, wear a proper mask and wear it properly
Also, thank you to @trishgreenhalgh who has been sharing and publishing this knowledge for nearly a year, and for all the other medical professionals who have been doing everything they can to teach us about *why* and *how* masks work to protect other people.

There's been a lot of talk about the missionary killed by the natives of North Sentinel Island. They're probably so aggressive because of this weirdo, Maurice Vidal Portman. So here's a big thread about this creep and some facts from my decade-long obsession with the island.


The Sentinelese are often described as “uncontacted,” but this not strictly true. They had a very significant contact in 1880 with Commander Portman.

Portman, the black sheep third son of some minor noble, was assigned by the English Royal Navy to administer and pacify the Andaman Islands, a job he pursued from 1880-1900 with the full measure of his own perversity.


Portman was erotically obsessed with the Andamanese, and he indulged his passion for photography by kidnapping members of various tribes and posing them in mock-Greek homoerotic compositions.


During his 20 years in a sexualized heart of darkness, Portman measured and cataloged every inch of his prisoner’s bodies, with an obsessive focus on genitals.

global health policy in 2020 has centered around NPI's (non-pharmaceutical interventions) like distancing, masks, school closures

these have been sold as a way to stop infection as though this were science.

this was never true and that fact was known and knowable.

let's look.


above is the plot of social restriction and NPI vs total death per million. there is 0 R2. this means that the variables play no role in explaining one another.

we can see this same relationship between NPI and all cause deaths.

this is devastating to the case for NPI.


clearly, correlation is not proof of causality, but a total lack of correlation IS proof that there was no material causality.

barring massive and implausible coincidence, it's essentially impossible to cause something and not correlate to it, especially 51 times.

this would seem to pose some very serious questions for those claiming that lockdowns work, those basing policy upon them, and those claiming this is the side of science.

there is no science here nor any data. this is the febrile imaginings of discredited modelers.

this has been clear and obvious from all over the world since the beginning and had been proven so clearly by may that it's hard to imagine anyone who is actually conversant with the data still believing in these responses.

1/OK, I should really write another thread about university-centric regional development, because I think people often make some (very understandable) mistakes when thinking about this issue.

2/The biggest myth, I think, is that universities help regions by educating locals as undergraduates.

Skeptics of universities say: "But most of the people who graduate end up leaving."

3/In fact, most of what a university does for a regional economy is NOT about educating local kids.

Educating local kids is good for the nation, but doesn't help a region much.

The way a university helps a region is through

4/Undergraduates usually leave town after graduation.

But university RESEARCH pulls in OTHER smart people from other regions, and they stay there.

Here's a paper showing that this is the main way universities increase a region's human capital:

5/Research also pulls in business investment.

Companies want to partner with university labs, so they can commercialize the technologies the labs produce. So they invest in the labs, and sometimes they even put their offices in the town.

@avacta's AVA6000 approved by MHRA. Superb news. First dosing 'around mid-year'; first data to come within 3-4 months after that.

A summary thread on the significance of AVA6000 - and #AVCT's pre CISION platform as a whole - to both the oncology industry and to AVCT itself. 1/10

In very basic terms, #AVCT's pre CISION chemotherapies are essentially reformulated versions of existing, approved chemotherapies that have been used on cancer patients for many years - decades, even.

The pre CISION tech is simply an attempt to improve the safety profile... 2/10

...of the chemo.

Most therapeutics going through clinical trials look for an improvement of at least 20% over the existing industry-standard drug. A 50% increase in efficacy would usually be considered an astonishing result.

In pre-clinical mouse models for #AVCT's AVA6000 3/10

...18 times more pro-doxorubicin was found in the tumour than in the heart. Compare that to the 1:1 ratio of the standard doxorubicin.

What this means is that the pre CISION tech could be used to enable the giving of doses to patients that are multiple times more potent... 4/10

...than standard chemotherapy drugs - either in the form of greater number of cycles of chemo, or in the potency of the individual dose.

For example, in #AVCT's pre-clinical trials, pro-dox (AVA6000) doses were 6x more potent than the standard dox doses.

The results? The...5/10

This is a piece I've been thinking about for a long time. One of the most dominant policy ideas in Washington is that policy should, always and everywhere, move parents into paid labor. But what if that's wrong?

My reporting here convinced me that there's no large effect in either direction on labor force participation from child allowances. Canada has a bigger one than either Romney or Biden are considering, and more labor force participation among women.

But what if that wasn't true?

Forcing parents into low-wage, often exploitative, jobs by threatening them and their children with poverty may be counted as a success by some policymakers, but it’s a sign of a society that doesn’t value the most essential forms of labor.

The problem is in the very language we use. If I left my job as a New York Times columnist to care for my 2-year-old son, I’d be described as leaving the labor force. But as much as I adore him, there is no doubt I’d be working harder. I wouldn't have stopped working!

I tried to render conservative objections here fairly. I appreciate that @swinshi talked with me, and I'm sorry I couldn't include everything he said. I'll say I believe I used his strongest arguments, not more speculative ones, in the piece.

Surendra Ananth @surendraananth, you violated my conditional consent. I assented to unprotected intimate relations with you on the STRICT condition that you tell me if you have relations with anyone else. You failed to do so, and I became ill as a direct consequence.

You refused to reveal your own STI results to me, but claimed to others they were negative and alleged I had multiple other partners, slut-shaming me. You gaslit me saying you had told me about your other partners.

You called up @justice_sisters and @SistersinIslam to tell them I was crazy, jilted. You rebuffed attempts to organise a community mediation so we could address matters. You said I was crazy for speaking to your boss and father in an attempt to keep other women safe.

You have a PATTERN OF BEHAVIOUR of misogyny, harassment and sheer disrespect for women. This was sent to a friend of mine who has never expressed interest in you and has a partner.


You think women are playthings, notches on the bedpost. You, @surendraananth, are no human rights advocate.

An irony of facebook's situation.

Sheryl got her MBA at Harvard. One of the most famous cases (Extra Strength Tylenol) in one of the most famous classes (Business History) she took: in 1982, someone put cyanide in Extra Strength Tylenol capsules and killed 7 people in Chicago.

What do you do when someone turns your product into a weapon? When they use the system you built to harm? James Burke, CEO of J&J, was shockingly open with the public, he pulled the product and made significant packaging changes to make product safer (but not tamper-proof).

He over-shared every step along the way re investigation, redesign, stood up as both CEO and human. The reintroduction of new Extra Strength Tylenol succeeded. Burke saved the brand.

But four years later it happened again. A killer put cyanide in the capsules, this time a woman in Yonkers died. Same CEO, Burke, pulled the product again, completely changed the form factor from capsule to caplet and relaunched *again*. It worked *again*. How'd they do that?

Burke (CEO) tapped J&Js goodwill bank account w/ the public. Two big withdrawals from that bank account in four years + 8 dead bodies! But his honesty, openness, humanity (choked up about the deaths more than once), humility kept the goodwill bank balance positive the whole time.

You want to buy a house.

You take a loan from the bank.

The bank asks you, “what if you don’t pay back?”

You say, “take my home and sell it”.

(Thread)

That makes sense. The bank gives you a loan and in case you don’t pay, the bank will take over your house and sell it and recover its money.

That’s collateral.

Banks also lend money to big corporations. With them, banks don’t always have collateral.

So a loan where the bank has collateral is considered safer for the bank.

In the early 2000s, the banks in the USA were giving out loans to people for buying houses.

The economy had just recovered from the tech bubble in 2000 where many banks had given out loans to businesses that had shut down.

In that backdrop, the banks found giving home loans safer.

Speech Delay is most common in children nowadays

In ancient times, our grandparents used to follow typical natural way of caring the needs of a child. All they used were more of natural products than chemical based for the growth of child.


One of major step followed was to feed Gurbach Jadd/ Vasa Kommu/ Acorus Calamus for initiating good speech ability in a child. This stem was needed to babies on Tuesdays and Sundays in mother's milk.

Vasa is feed to baby after the 1st bath on 12th day in week. Weekly only thrice it is fed and named as :

Budhwar - Budhi Vasa
Mangalwar - Vaak Vasa
Ravi Vaar - Aayush Vasa

This stem is burnt and rubbed against the grinding stone in mother's milk or warm water to get a paste


The procedure to make it is in the link

https://t.co/uo4sGp7mUm

It should not be given daily to the child. Other main benefits are

1. It clears the phlegm in child's throat caused due to continuous milk intake. It clears the tracts and breathing is effortless.
2. Digestion

For children who haven't got their speech and is delayed than usual should feed this vasa on these days in week atleast for 6months. Don't get carried away with this dialogue
