But most end up in which the government thinks deep into the german culture of looking at stereotypes a question that is think the future of the country that im not playing. Lead it seems to take the most drama day out to you thus its all that a box im a joke join me to meet the german sunday. Post. Keep your distance and wear a mask its the advice thats been given to millions of people around the world and following that recommendation has become for many the norm. But others refuse to comply when. Suddenly. Theyre pointing at. 6 months into the pandemic the use of face masks is still up for debate so is the recommended approach is still the way to go. Welcome to your code 19 special here on the w im Chris Culliver in berlin these fun tired of breathing through them you might be as well but Scientists Say wearing face masks is imperative when trying to slow the spread of the corona and then theres the us nowhere is the discussion around mask wearing probably as polarizing as in the United States far from being merely tired of them many people simply never wanted to wear them are you going to allow the government to tell you you have to wear masks i. The time is now time for action thank you guys very much. Anti maskers people who against the wide consensus of Public Health experts either want to limit mask wearing or are against them completely running any of them through similar reasoning over at the end i dont wear a mask for the same reason i dont on where underwear things got a breeze i care were you. That there were was. There was that it was i was reading i thought it was. Where you are was god help the world. And on the other side critics have been taking the countrys most prominent anti mask her so far to task in increasingly creative ways. Just soft ruling and slow down. Your cover your free and. Bring. Them here remarkably he might have even gotten the message he started to change his tune as of late to me might have no problem actually i had a man is going to like the way i look ok i thought it was ok it was a dark black mask and i thought it looked ok and looked like the lone ranger but now i have no problem with that i think people feel good about it they should do it however the president s decreasing aversion to masks influences attitudes it will probably be mandatory massacring policies that will make the difference the number of states requiring nose and mouth coverings like new york and california are increasing but calls are getting louder for a nationwide masking call. See proponents say National Measures would decrease infection rates and save the country from another round of shutdowns and an estimated trillion dollar hit to its economy something most people would welcome maybe even and he massacres. Lets talk more about this with siddhartha verma here is an assistant professor of ocean and Mechanical Engineering at Florida Atlantic university what come to d. W. Sidhartha you examined the effectiveness of various types of masts and found significant differences which was the most striking result. So most striking thing was our little effect very thin singulair fabric adds. No doubt it is better than nothing so any sort of crease coming is better than not ring at all but effectiveness and depend not a lot on the type of use if youre using plot. And as well as on the fit on our faces so with most mass we noticed there was a lot of leakage from the dock where the mast basically theres a gap between our nose and the mass so its important to have a good fit thats comfortable as well as use good time if you will and fabrics so what would be the best fabric in order for the mass to work properly the best fabric that we tested was actually julie years of quilting cottons they were just stitched together and we fitted. Snugly on the face and you could see that they dont form motion on the jacket was restricted to barely 2 or 3 inches and that turned out to be. So if i have a mask like that or any other type how can i test if it is holding back erol soles in a proper fashion. So some people have suggested very simple desk would be holding up hold your mouse up to a light and if you do see that the mask blocks the light well its likely to be more effective ok what about wearing your mask with your nose out does that make any sense at all if you go out on the street you see people doing that. I ask is that some people do that. No you should keep your nose covered by the mass for 2 reasons 1st you know when we exceed that if we are infected we might be we will definitely x. Y. Just leaving droplets out and the risk is must do prevent the winner to some extent so. We would be protecting ourselves by countering are those its so we minimize the amount of droplets that we breathe as well and as these masks some in many styles and fashion are what is your mask of your choice. I actually wear surgical type mice and. Its because they are easily available but i have a few. Oh man. Ive stripped out between these types all right so the art of armor of the Florida Atlanta University thank you for talking to doubly sure thank you for having me. Now wearing your mask is particularly important when you cannot keep your distance because sometimes we have to visit these crowded places like a train station for example now i start up in munich is focusing on a new pedestrian control system to ensure that people will not have to pass each other and close proximity and still get to where they want to go on time. Preventing potentially dangerous crowds thats what this team of computer scientists and simulation experts is working on an accurate a start up based in munich the corona pandemic is also demanding that they take a few steps into the unknown. The team usually calculates evacuation plans and security measures for major events or passenger flow. Whats new is that they now want to protect passengers employees and visitors from cope and 19 as much as possible. I mean one of these items in the chronic crisis in particular has shown us that simulations now not only help with crowds of people but they can also help us to see how many people we can fit in a room while observing social distancing roles so it concerns Office Buildings but also train stations so that passengers can travel safely. The simulations are based on projections human avatars socalled agents followed lifelike movement patterns. John kerry r. D. Have built in social distancing that means we have a green circle around a person with the diameter of 3 meters or radius of one meter 50 how are they all supposed to get out now and here i can already see that maybe these people are going to come out too but theyll have to wait a bit who will actually go through a one meter wide door 1st if i have to keep a 1. 5 meter distance and you can see that the agents turn red from time to time that means theyve been under the minimum distance for a while. The test avatars are still moving about without fear of infection researchers are focusing on a new pedestrian control system to ensure that in the future people will not have to pass each other in close proximity to reach their destinations on time. We are already seeing Human Systems everywhere in our daily lives whether its the entrance to the supermarket and so on and so forth i think the Research Work we talk. About has something to do with the queuing system and actually tries to capture and describe whats happening there. And the findings can of course help us to plan cues with a different set of objectives. You have. The minimum distance can even shorten travel routes and waiting times and train stations are mezzanine the one way street regulation can stop people getting in each others way when getting off or changing trains. The accurate team combines user information in architectural data which it hopes will help facilitate a return to normal and that means pedestrian traffic and with that public life could flow a little more smoothly again. Its time now to answer your questions about covert 19 he is our science and science correspondent there. What are the risks of sharing bathrooms with non family members like at the office. This question has been coming up logged ever since the publication of a new study on the physics of how aerosols are generated when you flush the toilet chinese researchers who modeled it discovered that every time you flush without closing the seat cover it sends a plume of aerosols up into the air which will will hover for minutes and then eventually settle on surfaces with other studies indicating that the virus might at least some time survive passage through the digestive tract suddenly those public facilities we all need to visit once in a while look like a potentially dangerous environment especially because many public or shared toilets are also enclosed window list spaces that said the experts that ive read on this mostly dont expect them to become hotbeds of infection probably because everyones grown so leery of using public facilities if you have to though im you should of course take the standard precautions particularly when it comes to to washing your hands afterwards but but hopefully you were doing that anyway.
