Hate speech: Jagadish Karanth granted interim bail hours after arrest

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.

Newsroom, Feb 2: American business magnate Bill Gates has congratulated her daughter Jennifer Gates after she announced her engagement to her Muslim boyfriend Nayel Nassar.

“I am completely thrilled! Congratulations, @jenniferkgates and @nayelnassar”, commented the Microsoft boss to her daughter’s surprise Instagram story.

The proposal took place on a ski getaway. "Nayel Nassar, you are one of a kind. Absolutely swept me off my feet this past weekend, surprising me in the most meaningful location over one of our many shared passions," she wrote on Instagram. The pair does have one very significant shared passion - horses.

Nassar, 29, is a showjumper. Gates, 23, has famously grown up an equestrian, and has even competed against Steve Jobs' daughter.

In October, Nassar helped Egypt qualify for Tokyo 2020 - Egypt's first Olympic equestrian qualification in 60 years. He has been jumping since he was 10 years old and has the accolades to show for it - he has taken first place in a number of notable competitions, including the Longines FEI Jumping World Cup.

Nassar was born in Chicago to Egyptian parents and spent many of his formative years in Kuwait, where his well-to-do parents run an architecture and design firm, according to People. He is fluent in English, Arabic, and French.

He moved back to the US in 2009 and graduated from Stanford with an economics degree in 2013 - later, he supported Gates at her own Stanford graduation in 2018.

The couple received well wishes from many notable personalities on each of their Instagram posts, including comments from Bill and Melinda Gates, Georgina Bloomberg, and Eve Jobs.

Bengaluru, June 11: Amulya Leona, a college student, who was charged with sedition for raising "Pakistan zindabad" slogans in Bengaluru, has finally been granted bail. 

The court had denied her bail yesterday, saying she might abscond. But her lawyers had been pursuing another way of getting her out of jail where she has spent nearly four months.

Ms Leona's advocate, Prasanna R, said that the delay of the state in submitting a chargesheet in the case beyond the stipulated time meant she was eligible for "default bail".

"The default bail application was moved before the magistrate under whose jurisdiction the alleged crime was committed. The chargesheet has not been submitted by the state within 90 days. So default bail has been granted. We had moved the default bail plea on May 26 and again on May 29 when the court told us the earlier mail IDs had been disabled. A physical application was filed on June 2. The state filed the chargesheet on June 3," the lawyer said.

While the state tried to argue that they were entitled to an extension in the time allotted, the court hearing this aspect of the case gave an order favourable to Ms Leona. The process is on to release her.

The arrest of Ms Leona during a rally against the Citizenship (Amendment) Act or CAA in Bengaluru had led to a debate on the use of sedition charges.

The woman on a Facebook post had also said "zindabad" to many countries including India and Pakistan. She did also try to chant "Hindustan zindabad", but was soon silenced and whisked away. She was accused of sedition, causing enmity between communities and causing deliberate mischief.
