Christian missionaries a threat to unity of the country: BJP MP

Mumbai, Feb 6: The Reserve Bank of India, for the second straight time, on Thursday kept its key policy rate unchanged at 5.15 per cent, maintaining its accommodative policy stance as long as it was necessary to revive growth.

The central bank retained GDP growth at 5 per cent for 2019-20 and pegged it at 6 per cent for the next fiscal.

"Economic activity remains subdued and the few indicators that have moved up recently are yet to gain traction in a more broad-based manner. Given the evolving growth-inflation dynamics, the MPC felt it appropriate to maintain status quo,” the Monetary Policy Committee (MPC) said.

The six-member committee voted unanimously to hold rates, but also said that there is “policy space available for further action”.

Between February and October 2019, the RBI had reduced repo rate by 135 basis points.

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.

Raipur, Mar 13: Calling Jyotiraditya Scindia a "power-hungry" leader, Chhattisgarh Minister and Congress leader TS Singh Deo on Friday said that if someone joins another party to occupy the top position of the state that he should never become a Chief Minister.

When enquired if Deo has any plans to join the BJP in the future, he quickly said that he would never be able to relate himself with the "ideology" of the party.

"People may make claims but I will never join BJP, even if I get 100 lives I will never associate with that ideology. A person who joins BJP for not being able to become Chief Minister should never become a Chief Minister," he said while speaking to media in Raipur.

"A single person does not remain as captain forever, Kapil Dev got his chance when Gavaskar was there. Currently, Virat Kohli is the captain but in T20 there are different captains. Will Kohli join Pakistan's team if he is not made the captain? This is beyond understanding."

On Wednesday, Scindia joined BJP in New Delhi in the presence of party President JP Nadda. He had resigned from Congress a day earlier after meeting Union Home Minister Amit Shah and Prime Minister Narendra Modi.

He will file his nomination for the Rajya Sabha elections on March 13.
