PM Modi shares pic with Priyanka and Nick, wishes them ‘happy married life'

California, Jun 30: Online video-sharing platform YouTube on Monday banned several prominent channels, including those belonging to Stefan Molyneux and Richard Spencer.

The company banned six channels for repeatedly violating YouTube's policies.

According to The Verge, other channels banned include American Renaissance (with its associated channel AmRen Podcasts) and the channel for Spencer's National Policy Institute.

YouTube began taking stern measures on supremacist channels in June 2019.

"We have strict policies prohibiting hate speech on YouTube, and terminate any channel that repeatedly or egregiously violates those policies," the Verge quoted a YouTube spokesperson as saying.

"After updating our guidelines to better address supremacist content, we saw a 5x spike in video removals and have terminated over 25,000 channels for violating our hate speech policies," the spokesperson added.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.

Mumbai, May 12: Superstar Salman Khan on Tuesday released his latest romantic single "Tere Bina" featuring Jacqueline Fernandez while in quarantine at his Panvel farm house.

The actor, along with close family and friends from the industry, including Iulia Vantur, Waluscha De Sousa, is living in the farm house. This is the second song Salman has released amid the coronavirus pandemic, after "Pyaar Karona."

"About seven weeks ago, when we came to the farm, we didn't know we will be here under a lockdown. So we wanted to do things to keep ourselves busy. That's when we decided to do these songs. We launched 'Pyaar Karona' and now, we are launching 'Tere Bina'," Salman said in a statement.

The song, sung and directed by Salman, is composed by his friend Ajay Bhatia and written by Shab bir Ahmed.

The actor said he had the song "Tere Bina" with him for quite a while but because it wasn't fitting into any of his film, he decided to release it now.

Jacqueline said she didn't think they would be able to shoot the song, which they finished in four days of evening shoots, with such limitations.

"We are used to shooting songs on a large stage with grand production costs. There are costumes, hair, make up. All of a sudden, we find ourselves with a team of three people. For the first time, I was checking lighting and moving props around. It was a great experience and it taught us how to make the most of what we have," she said.

Salman recently sent out food packets and ration from his farm house to those affected by the lockdown.
