What is a QM-system?

We've compiled frequently asked questions about the novel coronavirus at the center of the current pandemic. Each section includes links to trusted health organizations. First things first: The coronaviruses are a family of viruses whose symptoms can range from the common cold to something more serious and potentially lethal, and a new coronavirus is currently spreading across the planet, affecting the daily lives of many. In December 2019, an outbreak of a new coronavirus (SARS-CoV-2) occurred in Wuhan, China. It causes a disease called COVID-19, which can lead to death, particularly for the elderly and people with serious chronic medical conditions. There are currently no vaccines or antiviral treatments available. More than 150 countries and territories, including the United States, have confirmed cases of the infection since the initial outbreak, and on March 11, the World Health Organization declared it a pandemic. What are its symptoms? According to the CDC, fever, cough, and shortness of breath are the main symptoms of COVID-19. Additional symptoms may include aches and pains, nasal congestion, runny nose, sore throat, and diarrhea. Severity of the symptoms range from mild to life-threatening—about 1 in 5 people who are infected require hospital care. How do I get tested? If you’ve had contact with someone with COVID-19 or live in a community experiencing an outbreak and develop a fever and other symptoms of the disease, the CDC recommends you call your healthcare provider. Tell them about your symptoms and potential exposure to the virus, and they’ll make a call on whether you should be tested. They'll also help determine the safest way to receive your test. More specific guidelines vary from state to state. NBC News has a handy guide here. It’s especially crucial that you call your medical provider if you’re elderly or have a serious chronic medical condition. Also, if you or a loved one are very sick (e.g., experiencing symptoms like difficulty breathing, persistent chest pain or pressure, confusion, or bluish lips or face), seek medical attention immediately. How does it spread? The CDC and researchers worldwide still have a lot to learn about COVID-19 and how it spreads. According to current knowledge, though, the coronavirus that causes COVID-19 is mainly spread from person to person through respiratory droplets. That means droplets from an infected person’s coughs and sneezes land on other people’s noses or mouths, or they breathe them in, and that infects them, too. It’s also possible that the virus can spread through people touching contaminated objects and then touching their mouth, nose, or eyes. How can we prevent it? According to the CDC, “the best way to prevent illness is to avoid being exposed to this virus.” Some steps you can take to limit your exposure to the virus: Regularly wash your hands for 20 seconds or use a hand sanitizer with at least 60 percent alcohol. Pay attention to hand hygiene, especially when you’ve been in a public place and after coughing, sneezing, or blowing your nose. Practice social distancing by increasing the space between you and other people. That means staying home as much as you can, especially if you feel sick. Disinfect frequently touched surfaces (like keyboards, doorknobs, and light switches) every day. Cover coughs and sneezes with the inside of your elbow or a tissue. Throw the tissue away immediately and wash your hands. Wear a facemask only if you are sick or are caring for someone who’s sick and can’t wear a facemask. How is coronavirus different from the flu? While there are some similarities between the symptoms of COVID-19 and the flu (most notably fever and dry cough) one of the biggest differences is that we know significantly less about COVID-19. But here is what we do know: COVID-19 is more infectious than the flu. The “basic reproduction number,” or R0, of an infection is the average number of people who catch it from a single infected person. The flu has an R0 value of 1.3, while the R0 value of COVID-19 is estimated to be much higher. Right now, COVID-19 seems more likely to kill than the flu. While the exact fatality rate of COVID-19 is not yet known, it appears to be much deadlier than the flu. Influenza has a mortality rate of 0.1 percent, and current estimates of COVID-19’s fatality rate range from 1.4 percent to 3.4 percent. There is currently no vaccine or treatment for COVID-19. Unlike seasonal flu, there is no widely available vaccine to protect against COVID-19 infection. Similarly, there are no antivirals to help to reduce symptoms and shorten the duration of the disease. For more information on this ever-developing COVID-19 pandemic, consult the Centers for Disease Control and Prevention’s page dedicated to the virus, found here.

I assume you’re referring to the difference between the glorious mustiness of a library and the glorious plasticy newness of a bookstore. That’s probably due to the fact that as paper ages, the cellulose within it decays, letting off that sweet, sweet book smell. Bookstore books haven’t had as much time to decay (unless it’s a used bookstore), leading to that different smell.

In a word, no, but scientists can make educated guesses. The closest living relatives of the dinosaurs are crocodilians and birds, and we can look to the ways they vocalize to give us a hint. Alligators and crocodiles use their larynxes to communicate—they’ll hiss, groan, and yes, roar (here’s a compilation of their sounds). Dinosaurs might have had larynxes, but since those don’t fossilize, it’s impossible to know for sure. Birds, meanwhile, use an organ called a syrinx, which seems to have evolved after dinosaurs. That might indicate that dinos couldn’t vocalize at all, which would be a bummer. However, there’s also a possibility that they evolved a unique way to vocalize. For example, based on studying their skulls and inner ears, some have theorized that hadrosaurs used their crests to bellow at each other. So, they probably didn’t roar, but bellowing can be pretty cool too, right?

How to be a gymnast. And be flexible like Sofie Dossi. Sofie Dossi inspires me.

It turns out that there are two musicians behind the Joe Exotic songs, and neither of them are the man himself. According to Vanity Fair, Vince Johnson and vocalist Danny Clinton, members of the Clinton Johnson Band, are the ones who wrote and recorded all the big cat hits, including “I Saw A Tiger” and “Here Kitty Kitty.” The two men do appear in the credits of Tiger King, but Joe Exotic insisted to his staff and crew that it was him performing the songs. And he also didn’t bother telling the real musicians that he was taking the credit. “I had no idea he was going to Milli Vanilli the songs,” Johnson told Vanity Fair. “It was a couple of months and two or three songs [into the collaboration] when I was on YouTube one night and just happened to look up Joe Exotic. And there he was, lip-syncing and acting like the ghost of Elvis [in these music videos]. I called him up, I was hot…And he bamboozled me about his reality show—that it was coming soon and he would make everything right as rain. I just wanted the proper credit.”

Easter is always on the first Sunday after the Paschal Full Moon, which, yes, does sound like some pagan witchcraft, but I assure you that’s official church policy. So, what’s a Paschal Full Moon, you might ask? It’s the first full moon after the vernal equinox. However, there’s an important caveat: The church observes the vernal equinox on March 21 each year, whether it actually falls on that date or not. And this is only true of those following the Gregorian calendar; Eastern Orthodox Easter is figured on the Julian calendar instead, and their Easter is later. In 2020, the Paschal Full Moon falls on April 7, making Easter April 12.

Not exactly. The first year of a dog’s life is generally closer to 15 human years, and size and breed factor into how quickly dogs age. Smaller dogs tend to live longer than larger breeds, and they don’t become “seniors” until around 10 years, but they may mature faster in the first few years of life. A bigger dog might age more slowly in the beginning but be nearing middle age at 5 years. Medium-sized dogs fall somewhere in the middle.

On March 30, the Treasury Department and the Internal Revenue Service (IRS) announced that the payments will start going out in the next three weeks. If the IRS has your direct deposit information on file (as it does for roughly half the stimulus recipients), that time frame is likely accurate. Paper checks, however, will take longer. The IRS has a lot more information about how to make sure you get your payment in a timely manner here. Some precedents for reference: Under a new tax cut in 2001, the IRS took six weeks to start sending out rebate checks, and after a 2008 stimulus package was signed into law, checks weren’t sent out for three months.

According to the U.S. Securities and Exchange Commission, a bear market occurs when a broad market index falls by 20 percent or more over a period of at least a two months and the outlook is generally pessimistic. The average length of a bear market is 367 days, and they are usually accompanied by recessions—periods when the economy shrinks and unemployment rates soar.

no one its just a superstition for me I guess

A single spaghetti noodle is quite delightfully called a spaghetto. In Italian, “i” on the end of a word means it’s plural, the “o” here means it’s singular. So this goes for all your favorite pasta: fettucino, gnocco, my personal favorite raviolo, etc. Further, you technically don’t want a panini, you want a panino. I hope this brings you as much joy as it has brought me.

Nope! The list of things we know actually causes acne is not very long, but we do know this: Chocolate, and greasy foods, for that matter, are not on it. Medical professionals believe genetics, changing hormones, greasy makeup, and taking certain medications are the factors at play, not what you eat. However, if you already have acne, certain things can make it worse, like pollution, humidity, and stress.

Future so I know what will happen and I will be prepared and do what I have to

The National Recording Registry (part of the Library of Congress) is billing this year’s list of inductees as the “ultimate stay at home playlist,” so if you need some tunes to get you through quarantine, look no further. You can see all 25 inductees here, but here are some of the highlights to show how wonderfully wide-ranging the list is: – “Mister Rogers Sings 21 Favorite Songs From ‘Mister Rogers’ Neighborhood’ ” (album), Fred Rogers (1973) –“Y.M.C.A.” (single), Village People (1978) – “Fiddler on the Roof” (album), original Broadway cast (1964) – WGBH broadcast of the Boston Symphony on the day of the John F. Kennedy assassination, Boston Symphony Orchestra (1963) – “The Chronic” (album), Dr. Dre (1992) – “Hello Muddah, Hello Fadduh” (single), Allan Sherman (1963) The Library of Congress selected these titles from over 800 nominations to ensure that they’re preserved for future generations.

The until tomorrow challenge is where someone posts a picture (or a gallery of pictures) to their main Instagram account that’s somewhat unflattering or silly, captioning it with some version of “until tomorrow.” They then keep track of who likes the picture. After 24 hours, they delete the photo and send a message to everyone who liked it saying they have to do the same thing. And so on. It popped up mid-March, and I doubt it will continue much longer, since everybody will soon know not to double tap any pics with this cryptic message attached.

When you breath small vibrations in your cartilage create sound that you cant hear, these sounds are recorded on speakers. when the sound is emitted from the speaker it cancels out the same sound played back in a phenomenon called the reflex effect. because the sound waves are slightly distorted when they reach the speaker some of the inaudible sounds clash. other people don't hear the sounds because the sound travels through your sinuses. the clash of sounds makes a voice seem dry to the owner.

Leukemia. when I was 3 I had leukemia, and now when I go to hospitals I see little kids with it and my heart melts 'cause they don't know what's happening to their life. ;-;

no

Actually, yes. Shortly after parcel post was introduced in the early 1900s, several parents sent their small children though the mail. This was done with the help of sympathetic postal workers, most commonly over short distances in rural areas. And it was cost effective—in 1913, it cost just 15 cents to mail an 8-month-old baby to his grandmother. Before you get any big ideas, though, know that the fun came to an end in 1920 when the postmaster general officially outlawed sending people through the mail. How lame.

I feel you—I get that a lot, too. There are two likely answers. One is that your stomach produces excess acid when you’ve been ignoring your hunger for a while, and that acid can splash up into your esophagus and cause nausea. The other possibility is that you’re extra sensitive to ghrelin, the hormone our bodies make to alert us to our hunger. For some people, high levels of that hormone can make them slightly nauseous. If your nausea is severe, though, you should definitely talk to your doctor about it—it could be a sign of metabolic syndrome.
