Minorities feel safe under PM Narendra Modi, will vote for him: Shahnawaz Hussain

Mumbai, Feb 18: A group of citizens on Tuesday demanded a thorough inquiry into the death of special CBI judge Brijgopal Harkishan Loya in 2014.

The group has written a letter to Maharashtra Chief Minister Uddhav Thackeray, seeking a time-bound probe into the death of Loya.

Loya, who was hearing the high-profile Sohrabuddin Sheikh fake encounter case of Gujarat, died of a cardiac arrest in Nagpur on December 1, 2014, when he had gone to attend the wedding of a colleague's daughter.

Social activist Ashok Pai, addressing a press conference on behalf of the group, also demanded proper compensation for the judge's family, saying he was on an "official" tour.

Pai said on Tuesday he met NCP president Sharad Pawar, whose party is a key constituent of the Maha Vikas Aghadi (MVA) government in Maharashtra, and raised these demands with him.

Pawar assured to look into the demands, he said at the press conference at the Mumbai Marathi Patrakar Sangh.

"We have handed over a letter to Maharashtra Assembly speaker Nana Patole and dispatched a copy of the letter to Chief Minister Uddhav Thackeray (seeking a probe into Loya's death)," Pai said.

As the matter relates to "mysterious" death of a sitting judge of the CBI, all facts about it must be made public after a detailed and time-bound probe, Pai said.

The Loya death case had reached the Supreme Court.

The Supreme Court had held that Loya had died of "natural causes" and had rejected PILs seeking an SIT probe into the death, questioning their motive.

The SC had held that petitions were moved by political rivals to settle scores which was a serious attempt to scandalise the judiciary and obstruct the course of justice through a "frontal attack" on its independence.

New Delhi, Mar 19: Lawyer of Mukesh Singh, who is one of the four death row convicts in the Nirbhaya gang-rape and murder case, on Thursday mentioned a petition before the Registrar of the Supreme Court seeking an urgent hearing in the matter.

Advocate Manohar Lal Sharma, through the petition, sought directions to bring call record, documents and reports of his client through any probe agency and passed appropriate directions and measure to ensure justice in the matter.

The petition, however, has not sought a stay on the execution, which is scheduled for the morning of March 20. The petition is likely to be taken up for hearing today.

Earlier today, the apex court dismissed the curative petition of Pawan Gupta, another convict in the matter, who claimed juvenility at the time of the crime.

This comes as the four convicts -- Mukesh Singh, Akshay Singh Thakur, Vinay Sharma and Pawan Gupta -- are scheduled to be hanged at 5.30 am on March 20.

Meanwhile, several other petitions are also pending in the matter in different courts.

The case pertains to the brutal gang-rape and killing of a 23-year-old paramedical student in a moving bus on the night of December 16, 2012, by six people including a juvenile in the national capital. The woman had died at a Singapore hospital a few days later.

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.
