Tourist killed in Kashmir stone pelting; CM says her head hangs in shame

New Delhi, Jan 5: Senior Congress leader P Chidambaram on Sunday sàid it was "shameful" that Sadaf Jafar, SR Darapuri and Pavan Rao were arrested by the Uttar Pradesh Police for violence without any evidence against them.

He also said that it was a shocking admission by the police that there is no evidence of their involvement.

"Sadaf Jafar, S R Darapuri and Pavan Rao Ambedkar released on bail after police ADMITTED no evidence of their involvement in violence. Shocking admission," he said on Twitter.

"If that were so, why did the police arrest them in the first place? And how did the Magistrate remand them to custody without looking at the evidence," he asked.
"The law says 'find evidence, then arrest'. The reality is 'first arrest, then search for evidence'. Shameful," Chidambaram tweeted.

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.

Kanpur, Jul 11: "The Uttar Pradesh administration has done the right thing by taking action against my son," said an old and feeble Ram Kumar Dubey, father of gangster Vikas Dubey.

The father said his son killed eight police officials and it was an unforgivable sin.

"Had he listened to us, his life would not have ended this way. Vikas never helped us in any way. Due to him, even our ancestral property was razed to the ground. He also killed eight policemen, which is an unforgivable sin. The administration has done the right thing. Had they not done so, tomorrow others would have acted similarly," Ram Kumar said.

"It is the chief minister's duty to protect every individual. The police is an extension of that. He attacked them which cannot be forgiven. I will not even take part in his cremation," he added.

Ram Kumar Dubey said that his only appeal to the government is to allow him entry to his ancestral property now.

Vikas Dubey was cremated at Bhairav Ghat in Kanpur. His wife, younger son and brother-in-law were present and no other member of his family attended the last rites.

Vikas Dubey was arrested by the police in Ujjain on Thursday morning. He was on the run for the last six days and had come to the city to offer prayers at a temple, where he was identified by a security guard.

He was killed in an encounter by the Uttar Pradesh Police earlier today after he "attempted to flee".

The gangster was the main accused in the encounter that took place in Bikru village in Chaubeypur area of Kanpur last week, in which a group of assailants opened fire on a police team, which had gone to arrest him.

Eight police personnel were killed in the encounter.

Vikas Dubey managed to escape after the incident. Uttar Pradesh police had launched a hunt and raised a bounty on him for Rs 5 lakh.
