PFI backs Dalit agitation against dilution of SC/ST Act

New Delhi, Jun 18: The Delhi High Court Thursday asked the Delhi Police to file status report on a plea by Jamia Coordination Committee member Safoora Zargar, who was arrested under the anti-terror law --UAPA -- seeking bail in a case related to communal violence in northeast Delhi during protests against the Citizenship Amendment Act in February.

Zargar, M Phil student of Jamia Millia Islamia University, is more than four months pregnant.

Justice Rajiv Shakdher issued notice to the police and asked it to file a status report on the bail plea.

The high court listed the matter for further hearing on June 22.

Zargar, who was arrested by the Special Cell of Delhi Police on April 10, has challenged the June 4 order of the trial court denying her bail in the case.

The trial court, in its order, had said “when you choose to play with embers, you cannot blame the wind to have carried the spark a bit too far and spread the fire.”

It had said that during the course of investigation a larger conspiracy was discernible and if there was prima evidence of conspiracy, acts and statements made by any one of the conspirators, it is admissible against all.

The court had said that even if there was no direct act of violence attributable to the accused (Zargar), she cannot shy away from her liability under the provisions of the Unlawful Activities (Prevention) Act (UAPA).

However, the trial court had asked the concerned jail superintendent to provide adequate medical aid and the assistance to Zargar.

The police had earlier claimed that Zargar allegedly blocked a road near Jaffrabad metro station during the anti-CAA protests and instigated people that led to the riots in the area.

It further claimed that she was allegedly part of the “premediated conspiracy” to incite communal riots in northeast Delhi in February.

Communal clashes had broken out in northeast Delhi on February 24 after violence between citizenship law supporters and protesters spiralled out of control leaving at least 53 people dead and scores injured.

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.

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.
