Thiruvananthapuram, Apr 14: The Kerala government on Monday requested Prime Minister Narendra Modi to arrange special flights to the Gulf to bring back non resident Keralites stranded there due to the lockdown.

In a letter to Modi, Chief Minister Pinarayi Vijayan said many Keralites who had gone on visit visas and in search of employment were finding it difficult to continue there without jobs.

"While we appreciate the constraints faced in allowing international travel as the threat of COVID-19 has not yet receded, it is requested that special consideration to their needs be given and at an earliest opportune time, the Government of India consider arranging special flights to bring these people back," Vijayan said in the letter.

All International health protocols can be followed while extending this facility, he said and assured that testing and quarantine needs of Keralites who are returning would be undertaken by the state government. During the video conferencing the Prime Minister had with Chief Ministers on April 11, this matter had been broght to Modi's notice, Vijayan said.

New Delhi, Mar 20: Bodies of the four Nirbhaya convicts who were hanged on Friday morning at Tihar Jail have been sent to hospital for a post-mortem, following which it will be handed over to the families, according to an official.

After the hanging at 5:30 am today, the bodies were taken from Tihar Jail to Deen Dayal Upadhyay (DDU) Hospital for post mortem at around 8:20 am.

Tihar jail Director-General Sandeep Goel said that the bodies will be handed over to the families after the post mortem.

The families, however, will have to give a written undertaking that they will not make a public demonstration of the cremation or burial of the executed person.

The superintendent will also consult the District Magistrate and the Deputy Commissioner of Police for arrangements for the disposal of the body.

The post mortem comes in line with the Supreme Court's order in Shatrughan Chauhan's case in January 2014, which had mandated the same observing that there is a dearth of experienced hangman in the country.

"By making the performance of post mortem obligatory, the cause of the death of the convict can be found out, which will reveal whether the person died as a result of the dislocation of the cervical vertebrate or by strangulation which results on account of too long a drop," the apex court had said in its order.

"Our constitution permits the execution of death sentence only through the procedure established by law and this procedure must be just, fair and reasonable," the order added.

All four convicts in the 2012 Nirbhaya gang-rape and murder case -- Akshay Singh Thakur, Pawan Gupta, Vinay Sharma, and Mukesh Singh -- were hanged till death at 5:30 am this morning.

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.

One of the adults accused had allegedly committed suicide in the prison during the trial, while the juvenile was released from a correction home after a period of three years.

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.
