🌤 شبیه‌سازی تأثیر ماسک بر مهار قطرک‌هایی که در زمان سرفه خارج می‌شوند با ابرکامپیوتر فوگاکو در ژاپن نشان داده است که

اگر ماسک فیت نباشد، تنها ۶۹٪ کارآیی دارد.

اگر ماسک فیت شده باشد ۸۱٪،

اگر محکم فیت شده باشد ۸۵٪

و اگر ماسک دوم پارچه‌ای روی ماسک اول که فیت باشد قرار داده شود ۸۹٪ کارآیی خواهد داشت.

این درصدها به جنس ماسک هم بستگی دارد.

Telegram | DID YOU KNOW?

Date: |

Given the pro-privacy stance of the platform, it’s taken as a given that it’ll be used for a number of reasons, not all of them good. And Telegram has been attached to a fair few scandals related to terrorism, sexual exploitation and crime. Back in 2015, Vox described Telegram as “ISIS’ app of choice,” saying that the platform’s real use is the ability to use channels to distribute material to large groups at once. Telegram has acted to remove public channels affiliated with terrorism, but Pavel Durov reiterated that he had no business snooping on private conversations. If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means it’s less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isn’t as secure earned it some criticism. If you’re looking for something that is considered more reliable by privacy advocates, then Signal is the EFF’s preferred platform, although that too is not without some caveats. In addition, Telegram's architecture limits the ability to slow the spread of false information: the lack of a central public feed, and the fact that comments are easily disabled in channels, reduce the space for public pushback. Since January 2022, the SC has received a total of 47 complaints and enquiries on illegal investment schemes promoted through Telegram. These fraudulent schemes offer non-existent investment opportunities, promising very attractive and risk-free returns within a short span of time. They commonly offer unrealistic returns of as high as 1,000% within 24 hours or even within a few hours. The regulator said it had received information that messages containing stock tips and other investment advice with respect to selected listed companies are being widely circulated through websites and social media platforms such as Telegram, Facebook, WhatsApp and Instagram.
