HC issues notice to PM Modi over preventing ex-soldier from contesting against him

Mumbai, Jan 12: Thousands of citizens on Sunday congregated in Mumbai's suburban Jogeshwari to oppose the new citizenship law, the proposed NRC and NPR.

They also condemned last Sunday's violence on the JNU campus in Delhi, where masked men ran riot and attacked students. Leftist organisations had claimed RSS-affiliated ABVP's role in the attack, a charge denied by the students' body.

Former Tata Institute of Social Science (TISS) general secretary Fahad Ahmed told PTI that they assembled under the aegis of 'Hum Bharat Ke Log' in Millat Nagar area.

"Prime minister Narendra Modi should call 56 students from across the country to debate on the CAA, NRC and NPR," Ahmed said in an apparent jibe at Modi's "56 inch chest" remark, which the latter had made ahead of the 2014 Lok Sabha polls.

"Why the PM is not talking to us? Why is he not communicating? Even the Britishers used to talk to Indians whom they ruled, but our PM is not talking to poor people," he alleged.

Bollywood actor Sushasht Singh also spoke on the occasion.

"We are people of this country and such acts (CAA) are tarnishing the image of our country," he said.

At the gathering, people waved banners with slogans like "I Am From Gujarat, My Documents Burned in 2002", "No CAA, Boycott NRC, Stop Dividing India, Don't Divide us", "Save Constitution", written on them.

A large number of police personnel were present at the venue.

The Citizenship Amendment Act (CAA), which was notified on January 10, grants Indian citizenship to non-Muslim minorities migrated to India from Afghanistan, Pakistan and Bangladesh till December 31, 2014, following persecution over their faith.

Massive protests were witnessed against the CAA, mainly by the student community, since its passage by Parliament in December last year.

Opposition parties have been dubbing the CAA an "anti-Muslim" legislation, a charge being debunked by the government.

The Congress and other parties like the TMC have also opposed the proposed National Register of Citizens (NRC) and the National Population Register (NPR).

Union home minister Amit Shah has said that the government won't rest until persecuted refugees are granted Indian citizenship.

New Delhi, Feb 11: Celebrations broke out at the AAP headquarters here as early vote-counting trends for the Delhi Assembly polls on Tuesday showed a comfortable victory for the Chief Minister Arvind Kejriwal-led party.

The headquarters were decorated with blue and white balloons and big cut-outs of Kejriwal were placed in different parts of the party office.

"We knew it. We have changed the politics of this country. Now it is Delhi, next is India," said Sanjeev Singh, a party volunteer from Hari Nagar.

Another volunteer Fareen Khan said, "We hope we get such a clear majority that a message goes out that doing Hindu-Muslim politics will not work anymore."

The Aam Aadmi Party (AAP) is leading in 26 seats while the BJP is leading in 14 seats, according to early trends by the Election Commission.

According to the EC's website, AAP convenor Kejriwal is leading in his New Delhi constituency.

Kejriwal reached the party office as the counting of votes got underway.

Counting centres are spread across 21 locations, spanning 70 constituencies.

Polling for the 70-member Delhi Assembly was held on Saturday.

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.
