Death threat to actor after standing against lynchings

Jan 8: Bollywood star Deepika Padukone on Tuesday visited the Jawaharlal Nehru University (JNU) to express solidarity with the students who were attacked by a mob, but she did not address the crowd.

The actor reached the university campus at around 7.40 pm and attended a public meeting, called by JNU Teacher's Association and JNUSU in response to Sunday's attack on students and teachers by a masked mob armed with sticks and rods.

Deepika stood as former JNUSU president Kanhaiya Kumar was raising azaadi slogans and left by the time current president Aishe Ghosh started speaking.

The actor's decision to not address the crowd prompted Ghosh to comment, "when you are in a position, you should speak up".

"There are many people in Bollywood who do not put forth their views when they are not be aired. They are considered role models. I appeal to them: Make inspiring films after something has happened but when you are in that position, also talk about the story that is currently happening," she said.

Later, Ghosh said that Deepika expressed solidarity with the JNU students.

Deepika is in the capital to promote her upcoming release, Meghna Gulzar-directed "Chhapaak".

On Monday, the 34-year-old actor told a news channel that she feels proud that people have come out and raised their voice without fear, in reference to the protests against the amended Citizenship Act, the National Register of Citizens and violence in JNU.

"I feel proud to see that we aren't scared to express ourselves... I think the fact that we are thinking about the country and its future.... Whatever may be our point of view, it's nice to see," Deepika told NDTV India.

"I feel proud about it that people are coming out -- be it on the streets or wherever they are -- they are raising their voice and expressing themselves as it is important. If we want to see a change in life and society, it is important that a point of view be put forward," she added.

Kochi, Jun 27: The Kerala government on Friday submitted an application in a local court requesting to stop the prosecution of ivory possession case against Malayalam film actor Mohanlal.

In the application for withdrawal of prosecution, the government has requested the court to stop the prosecution "immediately for the interest of justice".

''The legality of the possession of two elephant tusks by Mohanlal was accepted by the competent authority under the Wildlife (Protection) Act, 1972 by issuing him a certificate of ownership. The possession and custody of the elephant tusks thus become legal after the Chief Wildlife Warden (CWW) issued him the certificate," the state government said.

"Further conduct of the criminal trial may go against the good faith amongst the parties as far as the certificate of ownership issued to Mohanlal is concerned. One cannot go back from that ownership certificate and it was stopped from contradicting, deny or declare to be false the previous statement made by the actor in the court," it added.

"The government should not be allowed to revert from its promises in order to keep the faith of the people and in the interest of good governance," the government further said.

The case was registered by the forest department in 2012. The state government submitted the application in Kuruppampady Judicial Magistrate Court, which will hear the matter on July 24.

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.
