Azaan from mosques causes noise pollution: Tripura governor

New Delhi, Jan 18: Asha Devi, the mother of the 2012 Delhi gang-rape victim, on Saturday slammed senior lawyer Indira Jaising for her suggestion that she should forgive her daughter's rapists.

"Who is Indira Jaising to give me such a suggestion? The whole country wants the convicts to be executed. Just because of people like her, justice is not done with rape victims," Asha Devi said here.

"Cannot believe how Indira Jaising even dared to suggest this. I met her many times over the years in Supreme Court, not even once has she asked for my well being and today she is speaking for the convicts. Such people earn their livelihoods by supporting rapists, hence rape incidents do not stop," she added.

Asha Devi further accused Jaising of using "the garb of human rights" to make a living.

'People like her keep earning money under the garb of human rights. I do not need her suggestions... Just because of people who think like her incidents like rape keep happening, she is a disgrace to women," she said.

Earlier yesterday, Indira Jaising, through a tweet, had urged Asha Devi to forgive the perpetrators and had used the example of Congress interim president Sonia Gandhi, who had forgiven Nalini, one of the convicts who was given the death penalty by the courts.

"While I fully identify with the pain of Asha Devi I urge her to follow the example of Sonia Gandhi who forgave Nalini and said she did not want the death penalty for her. We are with you but against the death penalty," Jaising's tweet read.

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.

Mumbai, Mar 28: Industrialist Ratan Tata on Saturday announced that Tata Trusts has committed Rs 500 crore for the medical supplies and equipments which will help combat the coronavirus outbreak.

"The COVID-19 crisis is one of the toughest challenges we will face as a race. The Tata Trusts and the Tata group companies have in the past risen to the needs of the nation. At this moment, the need of the hour is greater than any other time," said Ratan Tata, in an official release.

"Tata is committing Rs 500 crore for: personal protective equipment for the medical personnel on the frontlines; respiratory systems for treating increasing cases; testing kits to increase per capita testing; setting up modular treatment facilities for infected patients and knowledge management and training of health workers and the general public," Tata added.
Tata Chairman also expressed his deep gratitude for the members of all the organizations who are fighting coronavirus at the frontline, puting their life at risk.

"The Tata Trusts, Tata Sons and the Tata group companies are joined by committed local and global partners as well as the government to fight this crisis on a united public health collaboration platform which will strive to reach out to sections that are underprivileged and deprived," he added.

According to the Ministry of Health and Family Welfare (MoHFW), there are 873 confirmed cases of coronavirus cases in the country and 19 fatalities have been reported.
