Indian-American bags US Presidential Award for combating human trafficking

New Delhi, May 19: In a fresh blow to saffronite journalist Arnab Goswami, the Supreme Court of India today rejected his plea seeking transfer of the investigation of a case, filed against him for defaming Congress interim president Sonia Gandhi, to the CBI. The court also refused to quash the FIRs filed against him.

Goswami, editor-in-chief of Republic TV, has been booked in connection with a TV show on the gathering of migrants outside Bandra railway station on April 14. This apart, multiple FIRs have been filed against him for his show on Palghar lynching. In that show, he had posed certain questions on the incident to Congress President Sonia Gandhi, following which Congress workers lodged complaints against him in various states.

Extending Goswami’s interim protection from arrest by three weeks, the Supreme Court said, “Right of a journalist under 19 1 (a) higher…Free citizens can’t exist if news media can’t speak.”

During the earlier hearing, Senior Advocate Harish Salve, appearing for Goswami, had urged the court to transfer the probe to an agency like CBI. He said the “nature of the” second FIR against Goswami over a show on the migrant gathering outside Bandra station on April 14 “shows that it’s arm-twisting tactic”. 

“They are trying to stifle an unpleasant voice. This is a political party targeting a journalist. All complainants are members of one political party. They have a problem with the government. They want to teach this journalist a lesson,” he added.

Objecting to Salve’s plea to transfer the case to the CBI, Maharashtra government counsel, Senior Advocate Kapil Sibal, had said, “CBI investigation will go into your hands”. 

Sibal denied that Goswami was being harassed and said he was only asked relevant questions. He said Goswami should “stop this communal violence and communal mongering”.

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.

New Delhi, Jan 10: An IPS officer's thumb was bitten by a woman protester when he was pushing back agitators, who were trying to march towards the Rashtrapati Bhawan here on Thursday, police sources said.

The protesters had gathered after a call was given by JNU Students' Union president Aishe Ghosh to march towards President's House to demand the removal of University's Vice Chancellor, M Jagadesh Kumar.

Ingit Pratap Singh, a 2011 batch officer, who is currently posted as the additional deputy commissioner of the southwest district, was injured in the attack.

According to sources, Singh was trying to pull a male protester when the woman, in a bid to shield her friend, bit Singh's left thumb.
