![]() Of course you will continue to find information about the current and upcoming radio program with us. The new podcast section not only offers exciting content, but is now neatly organized and searchable. On the home page you will find program highlights, current audio, videos, events and the famous soccer betting game, as well as weather forecasts and regional news. Save energy or protect your eyes: If you tap on the radioeins logo at the top of the app, you can switch dark mode on and off, regardless of your smartphone's operating system. With the new app, we are fulfilling one of the most urgent user requests: all podcasts, music programs and contributions can now be fast-forwarded and rewound as desired.Ībove all, we now have a timeshift player that you can use to listen to the last four hours of radioeins! Either slide the timeline to the left or tap one of the items from the playlist and you're ready to listen in full beauty to that half-missed interview or song that didn't sound so uninteresting. The new app is currently available in German and English, but is expected to be released in other languages as well.The radioeins app: with completely new functions! "The bad news is that there is a greatly increased risk of infection." Mohsen Bagheri adds, "The good news, however, is that FFP2 masks and medical mouth-nose protection greatly mitigate the risk, especially when they fit tightly to the face." "We are confident that with the new theory and the new data, our app represents the risk of infection in closed, well-mixed rooms very well," says Eberhard Bodenschatz, director at the Max Planck Institute in Göttingen. "This allows us to determine the viral load in an indoor environment very well." Compared to many similar apps that exist around the world, the HEADS app therefore determines a higher risk of infection. "With our holographic and particle tracking measurements, we now know the large aerosols very well," says Mohsen Bagheri, head of a research group at the Max Planck Institute for Dynamics and Self-Organization. ![]() Using a statistical method that takes this fact into account, the HEADS app now enables a particularly reliable estimate of virus exposure in enclosed spaces. This is because they can contain several viruses, which increases the risk of infection when inhaled. The larger the aerosol droplets, the more dangerous they can beĮven for aerosol droplets with a diameter of less than 50 micrometres, the larger they are when released, the more harmful they can be. As the researchers measured on more than 130 test subjects, there are many small aerosols and only a few large ones. The model behind it is now up-to-date with the latest scientific findings and in particular takes into account the size distribution of the aerosols released with the air we breathe. The Göttingen team now asked themselves how high the risk of infection from these aerosols is in a closed, well-mixed environment, and developed the HEADS app based on their own research results and findings from other groups. Droplets smaller than 50 micrometers in diameter - equivalent to the radius of a fine woman's hair - dry quickly, become lighter particles, and as such remain airborne longer. Droplets larger than about 50 micrometers fall quickly to the ground, so the risk of infection from them can be minimized by keeping people at least 1.5 meters apart. ![]() Droplets typically vary in size from about 100 nanometers - about the diameter of a single virus - to about one millimeter. The main factor in the spread of Sars-CoV-2 and other pathogens are droplets that virus carriers release with the air they exhale. All users have to enter into the app are a few parameters, such as the size of the room, the number of people present, and whether these people are just breathing, talking loudly, or perhaps singing. It can be used to calculate the risk of infection for a certain number of people in indoor spaces that can be as large as 100 square meters, twice the size of a classroom. To better assess the risk of infection indoors, the Max Planck Institute for Dynamics and Self-Organization and the Institute of Hospital Hygiene and Infectiology (IK&I) at the University Medical Center Göttingen (UMG) have released the free web app HEADS (Human Emission of Aerosol and Droplet Statistics). Therefore, especially in light of new mutations, it is important to know what the risk of infection is in different situations and how it can be minimized. ![]() However, ways must be found to return to a reasonably normal life even with the Sars-CoV-2 coronavirus. A new, tighter lockdown may soon be another attempt to reduce the number of Covid 19 cases. ![]()
