COVID -19: Fabric masks should have three layers of different material

The World Health Organisation (WHO) has published an updated guidance on the use of face masks for control of COVID-19.

In his opening remarks at a media briefing on Covid- 19 last Friday, WHO Director-General Dr Tedros Adhanom Ghebreyesus said the guidance is based on evolving evidence, and provides updated advice on who should wear a mask, when it should be worn and what it should be made of.

He said WHO has developed this guidance through a careful review of all available evidence, and extensive consultation with international experts and civil society groups.

“I wish to be very clear that the guidance we are publishing today is an update of what we have been saying for months: that masks should only ever be used as part of a comprehensive strategy in the fight against COVID.

“Masks on their own will not protect you from COVID-19,” he emphasised.

He said the updated guidance contains new information on the composition of fabric masks, based on academic research requested by WHO.

“Based on this new research, WHO advises that fabric masks should consist of at least three layers of different material. Details of which materials we recommend for each layer are in the guidelines.”

According to the latest guidelines, cloth masks should consist of at least three layers of different materials: an inner layer being an absorbent material like cotton, a middle layer of non-woven materials such as polypropylene (for the filter) and an outer layer, which is a non- absorbent material such as a polyester or a polyester blend.

“Fabric cloths (e.g., nylon blends and 100 percent polyester) when folded into two layers, provides 2-5 times increased filtration efficiency compared to a single layer of the same cloth, and filtration efficiency increases 2-7 times if it is folded into 4 layers. Masks made of cotton handkerchiefs alone should consist of at least 4 layers, but have achieved only 13 percent filtration efficiency. Very porous materials, such as gauze, even with multiple layers will not provide sufficient

These Three Things Need to Happen Before Stocks Bottom Out, Credit Suisse Says

By Callum KeownUpdated March 16, 2020 10:29 am ET / Original March 16, 2020 9:58 am ET

When will stocks reach the low and what will the recovery look like?

Credit Suisse said it needed to see three conditions required for a trough in global stocks:

1. Clear-cut fiscal easing in the U.S. — which happened late on Sunday;

2. A peak in daily infection rates

3. A trough in global purchasing managers indexes, which it said could happen in May.

In the severe acute respiratory syndrome crisis, markets bottomed out a week daily new infections hit a peak, the bank’s research analysts said.

“We expect a V-shaped recovery ultimately and would be buyers of equities on a one-year view; we believe markets will rise 15-20% over the next 12 months. 

“Historically when we look at exogenous supply-side shocks, markets tend to rise very rapidly from the trough (SARS, Kobe earthquake, Suez, 1987),” they said.

The analysts, led by Andrew Garthwaite, favored stocks in Asia (a commodity-importing region on top of the virus) relative to Europe. In a new realistic worst-case scenario, U.S. earnings would drop 20% and the S&P 500 would fall to 2,200 points, they added.

They also expected “massive” monetary and fiscal stimulus. “This should enable a V-shaped recovery that by the end of 2021 could make up for much of 2020’s lost growth,” they said.

Coronavirus can stay infectious for 3 days on surfaces. But it’s still okay to check your mail.

March 13, 2020 at 8:00 AM EDT

Excerpt: Scientists studying the novel coronavirus are quickly uncovering features that allow it to infect and sicken human beings. Every virus has a signature way of interacting with the world, and this one — SARS-CoV-2, which causes the disease covid-19 — is well-equipped to create a historic pandemic.

Corona virus covid-19

The coronavirus may take many days — up to 14 — before an infection flares into symptoms, and although most people recover without a serious illness, this is not a bug that comes and goes quickly. A serious case of covid-19 can last for weeks.

This coronavirus can establish itself in the upper respiratory tract, said Vincent Munster, chief of the Virus Ecology Section of Rocky Mountain Laboratories, a facility in Hamilton, Mont., that is part of the National Institute of Allergy and Infectious Diseases. That enables the virus to spread more easily through coughing and sneezing. Munster and his colleagues have been studying the novel coronavirus under laboratory conditions to better understand its viability outside a host organism — in the air and on surfaces.

Those experiments found that at least some coronavirus can potentially remain viable — capable of infecting a person — for up to 24 hours on cardboard and up to three days on plastic and stainless steel.

Three privacy tools that block your Internet provider from tracking you | PCWorld

It’s official: Congress has sold you out to Internet service providers, passing a bill that dismantles Internet privacy rules and allows ISPs to sell your web history and other personal information without your permission. Assuming President Trump signs the bill into law, it means anyone concerned about privacy will have to protect themselves against over zealous data collection from their ISP.

Some privacy-conscious folks are already doing that—but many aren’t. If you want to keep your ISP from looking over your shoulder for data to sell to advertisers, here are three relatively simple actions you can take to get started.

* Use HTTPS Everywhere

* Get a paid virtual private network

* Adjust your DNS (Cloudflare is a public DNS at 1.1.1.1)

The Elevator Pitch – WOW, HOW, NOW APPROACH

elevator pitch - wow how now

Elevator Pitch
Elevator Pitch

Offered by Brian Walter, the prominent coach speaker, it is probably the simplest way of attracting your audience to your business plan. According to this approach, your presentation should be split into three stages:

An elevator pitch is a universal tool that can be employed in any networking opportunity. Thus, share it with your team so that everyone is prepared to pitch it as soon as an opportunity arises.

The most important point, however, is to remember that the core aim of your pitch is to show the value proposition your idea creates. So don’t try to hide it by digressing into irrelevant matter.

WOW. At this stage your main purpose is to attract a person’s attention by making a compelling and often surprising statement that will make them want to find out more.

HOW. Explain what it means and state what your role is in the process.

NOW. Use storytelling to tell a real-life example of how your idea works.

3-click rule — the magic number – UX Collective

3-click rule — the magic number

A maximum of information in a minimum of words.

UI UX design
UI UX design

This is a particularly deep belief for your graphic designer friends for 10 years, but we have come a long way, and the usability tests have shown it for a while…

I will not lie to you any longer, users of your services will not leave your site or application if they can not find the information they are looking for in 3 clicks.

The number of clicks needed does not affect the success rate and even less the satisfaction of users: the important thing is to have a smooth, easy and understandable navigation (yes, the rules of 3 adjectives affect me too).

The scent of information

The concept is a simple idea and quite primitive as the name suggests : to have a good hunt, you must follow a good smell!

On a website or an application, the smell will take shape with the content, scented with confidence, the right word, the good image.

A little like my previous article about form field (Form fields — Required vs Optional), never forget that the most important thing when designing a product is to give the user the feeling of being in the center of all the expectations.

It’s a bit like setting a trap for a hungry bear, bait him, feed him to your final goal and he will follow you without even realizing it.

The key is your content: put it in value, coated to bring your user to be tempted to immerse himself in it and especially not let him lose The scent of information !

Once lost, the user hesitates, it becomes difficult for him to finish the action, and he will eventually notice the number of clicks you ask him to do.

Do not waste time worrying about the number of clicks, worry about the scent of information.

Disclamer :

I already see the crowd of designer dissatisfied ‘yes that’s fine theory, but when you can do 2 click instead of 6 is better no?’

YES, of course, this article is meant to make you think, to give you concrete information about the different studies done about the 3 clicks rule, but do not get me wrong, when you can do 2 clicks instead of 6 without spoiling the navigation experience, made it, but do not forget The scent of information.

Legal Advice: Pound the Facts, Pound the Law, Pound the Table

Pound the Table

Harvard Law School professor Alan Dershowitz shares with his students a strategy for successfully defending cases.

“If the facts are on your side, Dershowitz says, pound the facts into the table. If the law is on your side, pound the law into the table. If neither the facts nor the law are on your side, pound the table.”

Quote Investigator: There is good evidence that Jerome Michael used a version of the saying while teaching, but the adage was in use before he graduated from Columbia Law School. QI has traced it back ninety-nine years and will present selected citations in reverse order.
