Congress an equal partner in GST decision, says PM Modi

Lucknow, Feb 2: In an early morning firing at Lucknow's Hazratganj, the city centre, Vishva Hindu Mahasabha state president Ranjit Bachchan was killed while he was out on a morning walk on Sunday.

Ranjit Bachchan was taking a stroll in Hazratganj in the morning when bike-borne assailants opened fire on him and killed him on the spot. The Mahasabha leader was shot in the head multiple times.

The incident took place near the CDRI building in Lucknow's Hazratganj.

In the firing, Ranjit Bachchan's brother also suffered bullet injuries. He has been rushed to the trauma centre. Ranjit Bachchan was a resident of Gorakhpur.

The early morning shootout in the Uttar Pradesh capital's central area has caused tension in the area.

Dinesh Singh, DCP Central Lucknow, said, "The body has been identified as of Ranjit Bachchan, who had gone out on morning walk when some unknown assailant shot him. A police team has been formed and further investigation is being carried out."

Before being associated with the Mahasabha, Ranjit Bachchan was a Samajwadi Party member and was often spotted with former UP chief minister Akhilesh Yadav.

The Samajwadi Party has hit out at the Yogi Adityanath government over the law and order situation in the state and demanded immediate resignation of the government.

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.

Bengaluru, May 22: Amazon.com Inc’s India unit said it would hire 50,000 temporary workers to meet a surge in online shopping in the country, where customers have been stuck indoors for two months in a lockdown to fight the coronavirus outbreak.

E-commerce firms faced massive disruption in the initial days of the lockdown in India, but a slow easing of the stringent regulations has allowed them to resume large parts of their operations.

"We want to continue helping customers all over India get everything they need so they can continue to practice social distancing," Amazon senior executive Akhil Saxena said in a statement on the company's blog. (bit.ly/2A1Wv7O)

“(The move) will also keep as many people as possible working during this pandemic while providing a safe work environment for them,” said Saxena, Amazon’s VP for customer fulfillment operations in APAC, MENA & Latam.

The temporary hires will work in Amazon’s fulfillment centers and as part of its delivery network, the company said, making the announcement at a time when various other companies in the country have been forced to cut jobs as they try to tide over the health crisis.

Amazon itself has pushed its annual global Prime Day event, traditionally a summer affair, to September, the Wall Street Journal reported on Thursday.

In India, where the Jeff Bezos-led company faces stiff competition from Walmart Inc’s Flipkart, Amazon earlier said it plans to create 1 million jobs by 2025.

The company also said on Thursday it plans to enter the food delivery business in India, pitting itself against well-established startups such as Swiggy and Zomato.
