Threads of a N95 mask at 25x, Omax Microscope

It's not new! I bought it last year on 11th July. As the picture isn't new either.

It just I want to upload something before traveling to Omrah on Friday to Friday.

 

And I wish to All happy vacation. :)

Testing the very functional Nokia N95.

I picked up this full-size Dodge Charger to take a drive around the San Francisco Bay Area for a day. I really liked it -- unsurprisingly roomy, decent engine, surprisingly manoeuvrable (see the front wheels all the way at the nose) and, I think, a good-looking car. Plus, it had Sirius (satellite radio), so I spent much of the drive listening to OutQ, the gay radio station, which seemed to be doing a live broadcast about Halloween costumes in New Orleans. Not exactly radio material, methinks, so after that it was time for a bit of Wagner.

 

I had an absolutely lovely drive, from SoMa over to Lombard Street (the Crookedest Street in the World), then over the Golden Gate, up to Mount Tamalpais, round to Fairfax, down to San Rafael, over to Richmond, then Oakland, then back over the Bay Bridge to SoMa. And in the evening, my friend Abe and I headed out to the Melting Pot in San Mateo. Mmm, Melting Pot.

 

Pluses: leg room, engine, radio, looks

 

Minuses: visibility, especially in the back seats, size in cities

Can face masks help slow the spread of the coronavirus (SARS-CoV-2) that causes COVID-19? Yes. Face masks combined with other preventive measures, such as getting vaccinated, frequent hand-washing and physical distancing, can help slow the spread of the virus. The U.S. Centers for Disease Control and Prevention (CDC) recommends fabric masks for the general public. People who haven’t been fully vaccinated should continue to wear face masks in indoor public places and outdoors where there is a high risk of COVID-19 transmission, such as crowded events or large gatherings. The CDC says that N95 masks should be reserved for health care providers. How do the different types of masks work? Medical masks Also called surgical masks, these are loosefitting disposable masks. They're meant to protect the wearer from contact with droplets and sprays that may contain germs. A medical mask also filters out large particles in the air when the wearer breathes in. To make medical masks more form-fitting, knot the ear loops where they attach to the mask. Then fold and tuck the unneeded material under the edges.

An N95 mask is a type of respirator. It offers more protection than a medical mask does because it filters out both large and small particles when the wearer inhales. Because N95 masks have been in short supply, the CDC has said they should be reserved for health care providers. Health care providers must be trained and pass a fit test before using an N95 mask. Like surgical masks, N95 masks are intended to be disposable. However, researchers are testing ways to disinfect and reuse them. Some N95 masks, and even some cloth masks, have valves that make them easier to breathe through. Unfortunately, these masks don't filter the air the wearer breathes out. For this reason, they've been banned in some places. A cloth mask is intended to trap respiratory droplets that are released when the wearer talks, coughs or sneezes. It also acts as a barrier to protect the wearer from inhaling droplets released by others.

The most effective cloths masks are made of multiple layers of tightly woven fabric like cotton. A mask with layers will stop more droplets from getting through your mask or escaping from it. How to get the most from your mask; The effectiveness of cloth and medical masks can be improved by ensuring that the masks are well fitted to the contours of your face to prevent leakage of air around the masks' edges. Masks should be snug over the nose, mouth and chin, with no gaps. You should feel warm air coming through the front of the mask when you breathe out. You shouldn't feel air coming out under the edges of the mask. Masks that have a bendable nose strip help prevent air from leaking out of the top of the mask. Some people choose to wear a disposable mask under their cloth mask. In that case, the cloth mask should press the edges of the disposable mask against the face. Don't add layers if they make it hard to breathe or obstruct your vision. Proper use, storage and cleaning of masks also affects how well they protect you. Follow these steps for putting on and taking off your mask: Wash or sanitize your hands before and after putting on your mask. Place your mask over your mouth and nose and chin. Tie it behind your head or use ear loops. Make sure it's snug.,Don't touch your mask while wearing it. If you accidentally touch your mask, wash or sanitize your hands. If your mask becomes wet or dirty, switch to a clean one. Put the used mask in a sealable bag until you can get rid of it or wash it. Remove the mask by untying it or lifting off the ear loops without touching the front of the mask or your face.

Wash your hands immediately after removing your mask.

Regularly wash cloth masks in the washing machine or by hand. (They can be washed along with other laundry.)

And don't forget these precautions: Don't put masks on anyone who has trouble breathing or is unconscious or otherwise unable to remove the mask without help. Don't put masks on children under 2 years of age. Don't use face masks as a substitute for physical distancing. What about face shields? The CDC doesn't recommend using face shields instead of masks because it's unclear how much protection shields provide. However, wearing a face mask may not be possible in every situation. If you must use a face shield instead of a mask, choose one that wraps around the sides of your face and extends below your chin.

Do you still need to wear a facemask after you’re fully vaccinated? After you're fully vaccinated, the CDC recommends that it's ok not to wear a mask except where required by a rule or law. However, if you are in an area with a high number of new COVID-19 cases in the last week, the CDC recommends wearing a mask indoors in public and outdoors in crowded areas or when you are in close contact with unvaccinated people. If you are fully vaccinated and have a condition or are taking medications that weaken your immune system, you may need to keep wearing a mask. You're considered fully vaccinated 2 weeks after you get a second dose of an mRNA COVID-19 vaccine or 2 weeks after you get a single dose of the Janssen/Johnson & Johnson COVID-19 vaccine. In the U.S., everyone also needs to wear a mask while on planes, buses, trains and other forms of public transportation. The World Health Organization (WHO) recommends medical masks for health care workers as well as for anyone who has or may have COVID-19 or who is caring for someone who has or may have COVID-19.``

The Covid-19 pandemic seems to have sorted us into three types based on our attitudes toward masking: Call them nervous maskers, never-maskers and uncertain maskers. The first feel guilty or nervous about unmasking, so they tend to default to wearing masks; the second feel angry and resentful about being told to mask, so they often refuse entirely. And the third group is just trying to do the right thing without a lot of certainty one way or another. Winter is coming, with its continued battles against delta or mu or another variant. We have better protections now (vaccinations, natural antibodies) but also are returning to higher-risk environments (nightclubs, offices, schools). To complicate matters, there are additional factors to consider such as waning immunity from vaccines and the potential of a bad flu season.

Fortunately, there have been a number of important studies on the efficacy of masking over the past 18 months. The good news is that the research suggests most of us can actually de-mask without guilt or worry in many instances — and not just outdoors. It tells us, for example, that plexiglass dividers are in most cases useless or worse. But relaxed refuseniks need a rethink, too — we shouldn’t be ditching masks entirely. On the contrary, the more people adopt a policy of tactical masking, taking situational factors into account, the lower the infection risk and the more freedoms we can enjoy again. As the probability of infection increases, mask wearers lower the risk of catching the virus compared with no masking. For N95 or FFP2 masks, the protection is far greater. Note: Relative reduction in risk-of-infection figures are for an infection probability of 4%.

It’s no wonder we’re either nervous, angry or confused about masks when you consider how masking guidance and conventions have been all over the map. It seems amazing now that the Centers for Disease Control and Prevention, the World Health Organization and various governments had warned against using masks in the early days of the pandemic. When Thomas Nitzsche, mayor of Jena, Germany, made the decision to require masks in public in early April 2020, his city became one of the first to do so. Infections dropped by up to 75% over the next few weeks. In May, the CDC said fully vaccinated people no longer needed to wear masks in most public settings. Two months later, as delta variant cases rose, the CDC revised that guidance. Now seven U.S. states — Hawaii, Illinois, Louisiana, Nevada, New Mexico, Oregon and Washington — require most people to wear masks indoors in public places. Some states, including Texas and Florida, bar local authorities from imposing Covid-19 restrictions, including mask-wearing. In places that view masking as an affront to liberty, university professors can’t even ask students to wear masks during office hours without putting their jobs at risk. In England, there was a general lifting of restrictions in July, though U.K. Health Secretary Sajid Javid said last week that masking may become mandatory again in some indoor settings this winter, depending mainly on whether hospitalizations from Covid spike. While masks are required on public transport, I’d say about half or fewer comply during my journeys. Many offices require workers to mask while walking around, but few Tory lawmakers are wearing them in the House of Commons. Scotland still requires masks to be worn in shops and restaurants while not seated, as well as on public transport. Berlin requires the medical-grade FFP2 masks on public transport. Certain regions of France also have masking requirements in place. But if you care about what the evidence says (and some people don’t), the jury is in: Masks help a lot. Take, for example, the study that shows most U.S. states that had high mask usage in one month avoided high Covid rates in the subsequent month, even after adjusting for masking policy, social-distancing policy and demographic factors. The majority of states with low mask usage ended up with high Covid case rates. Note: Low mask adherence means states that fall below the 25th percentile; high adherence are those states above the 75th percentile. Study analyzed data from April to October 2020.

The largest study yet on the effectiveness of masking, posted online in pre-print earlier this month, was a randomize trial conducted in 600 villages across Bangladesh covering a population of more than 340,000 adults. It offered strong evidence that masks, and surgical masks in particular, reduce virus transmission. Researchers found that a 29 percentage-point increase in mask adoption led to an 11% reduction in symptomatic SARS-CoV-2 prevalence, where surgical masks were distributed; and a 35% reduction in people over 60. Symptom reductions using surgical masks were not statistically significant in younger age groups. While vaccines have largely broken the link between infections and hospitalizations (and death), they haven’t eliminated the need for mask-wearing. Data released last week showed that two doses of the Oxford/AstraZeneca vaccine were 67% effective against delta-variant infections (compared with 80% for two doses of Pfizer/BioNTech’s). Infections can still be nasty; long Covid remains another reason for vigilance. Not only can fully vaccinated people catch and transmit the virus, but it is unvaccinated adults who are more mask-resistant. Since it’s estimated that around half of all transmissions come from asymptomatic persons, masks are still key to preventing infections. But masking shouldn’t be performative, as it often is with those uncertain maskers who just want to show they are being thoughtful. Which masks we wear, and especially how they fit, is important. Mind the Gap . While N95s offer a higher level of protection, a well-fitted surgical mask blocks most particles.

More particles get through mask; Of course, not all masks are created equal, as a recent study published in the journal Nature highlighted. The authors measured the thermal behavior of face masks in real time during inhalation and exhalation to determine the relationship between the fabric structure of the masks and their performance. Their experiment helped shed light on how aerosol-containing bacteria and coronaviruses penetrate three different kinds of masks — reusable face masks, disposable surgical masks and the N95 — and how we can evaluate air filtration performance.Reusable masks have longer, thicker fibers with a larger average pore diameter. Unsurprisingly, they have

higher levels of permeability, with the surgical mask coming second, followed by the F95 (similar to the FFP2 in Europe). Those findings should even help manufacturers create a new generation of masks that offer more breathability while also improving filtration. The CDC doesn’t recommend scarves and other headwear because they tend to be made from loosely woven fabrics. Loosely Denser fabrics such as cotton with a 600 thread count compared with cotton that is woven with 80 threads per inch, are much more effective. Mixed fabrics also tend to have better results. A study on masks with and without gaps shows that leaks can significantly reduce their effectiveness. In addition to materials, layering them can also improve efficacy. New lab evidence on different kinds of masks showed that a three-ply surgical mask blocked 42% of particles from a simulated cough; a three-ply cloth mask was pretty similar. But the protection jumped to 92% when a cloth mask was worn over a surgical mask. Comfort is important to being able to wear a mask for long periods of time. In addition to metal nose-bridge strips that can help a mask stay on better, straps that tie behind the head and mask extenders can help reduce soreness around the ears. Insertable filters can be replaced when masks get wet.

Masks will also help prevent more vaccine-resistant variants from emerging as well as higher rates of flu infections, which can also cause serious illness and even death. Even so, the research strips away some of the mask myths and can help all categories of maskers — nervous, nevers and uncertains — be more tactical and aware. To know whether a mask is a must-have, a good idea or entirely superfluous, check the risk factors the way you might a weather report in the mountains: How densely packed and how well-ventilated is the space you are entering? Will you be moving around or stationary? It’s certainly good to mask up in an elevator or on public transport where people are pretty close together. It’s probably not necessary in an open-planned, well-ventilated office, provided people observe a measure of social distancing. Then be mindful of the infection and vaccination rates where you are. If you are in Broward County, Florida, where 70% of over-18s are vaccinated, you’d be justified in having a more relaxed approach; drive next door to Glades County, where only 31% are vaccinated and infection rates are high, and you’ll want to be more vigilant. Similarly only 16% of over-65s in King County, Texas, are vaccinated compared with 70% next door in Knox County, where the CDC recommends even vaccinated people mask. By moving beyond the “hygiene theater” of practices that don’t offer much benefit while also accepting that there are many different levels of risk tolerance and factors that increase or lower situational risk, we can treat masking a little like checking the weather forecast. Some days require a little more covering up than others.
