'One Nation, One Election' will create confusion among voters: Deve Gowda

Kanpur, Jul 10: Kanpur encounter main accused Vikas Dubey, who was injured in an encounter with the police, died on Friday, the police said.

"Gangster Vikas Dubey arrested for killing eight policemen is dead," confirmed the police.

According to SP Kanpur West Anil Kumar, gangster Vikas Dubey attempted to flee after the car overturned. Dubey attempted to flee by snatching pistol of the injured policemen. However, he was shot in the retaliatory firing.

"Vikas Dubey attempted to flee by snatching pistol of the injured policemen after the car overturned. Police tried to make him surrender, during which he fired at the policemen. He was injured in retaliatory firing by police. He was later rushed to the hospital," SP Kanpur West told reporters here.

Dubey, the main accused in the Kanpur encounter was arrested by the police in Ujjain on Thursday morning. He was on the run for the last six days and had come to Ujjain to offer prayers at Temple, where he was identified by a security guard at the shrine.

The gangster is 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 allegedly opened fire on a police team, which had gone to arrest Dubey. Eight police personnel were killed in the encounter.

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

Bahua Dubey and Prabhat Mishra, close aides of the main accused, were killed in separate encounters in Etawah and Kanpur respectively, on Thursday.

The main accused's other aide Shyamu Bajpai was arrested by the Chaubeypur police following an encounter. He carried a reward of Rs 25,000, the police informed on Wednesday. Earlier the same day, Uttar Pradesh's Special Task Force (STF) gunned down Vikas Dubey's close aide Amar Dubey in Hamirpur district.

New Delhi, Jun 18: With the highest single-day increase of 12,881 COVID-19 cases reported in the last 24 hours, India's coronavirus count has reached 3,66,946 on Thursday.

This includes 1,60,384 active cases and 1,94,325 cured, discharged and migrated patients, according to the Union Health and Family Welfare Ministry.

Meanwhile, with 334 deaths being reported due to the infection, the toll due to the virus stands at 12,237 in the country.

There is a big increase in the number of confirmed cases in the country today as compared to the recent days when the spike had been limited to under 11,000 cases.

Maharashtra with 1,16,752 cases continues to be the worst-affected state in the country with 51,935 active cases while 59,166 patients have been cured and discharged in the state so far. The toll due to COVID-19 stands at 5,651 in the state.

The number of confirmed cases in Tamil Nadu also crossed the 50 thousand mark on Thursday and reached 50,193. The national capital is the third-worst affected by the infection in the country with the count reaching 47,102 today.

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.
