Mumbai, Mar 6: Harried Yes Bank depositors rushed to ATMs to withdraw cash but faced multitude of problems including closed down machines and long queues, after the RBI placed the bank under a moratorium, capping maximum withdrawals at Rs 50,000 per account for a month.

Aggravating the problems of depositors were difficulties accessing the internet banking channel, which ensured that they can't transfer the funds online as well. At an ATM in south Mumbai's Horniman Circle, with the RBI headquarters overlooking it, the shutters were pulled down.

The guard on duty said the machine was non-operational before he reported to work late in the evening and he was ordered to shut it after 2200 hrs. In the residential area of suburban Chembur, one ATM was dispensing cash but had a long queue of anxious depositors.

One man said it was still possible to withdraw up to Rs 50,000 in multiple transactions from the machine.

However, another machine nearby had run dry within minutes of the RBI announcement, a woman said.

The regulatory actions, undertaken by the RBI and the government, came hours after finance ministry sources confirmed that SBI was directed to bail out the troubled lender.

For the next month, Yes Bank will be led by the RBI-appointed administrator Prashant Kumar, an ex-chief financial officer of SBI.

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.

Bhopal, Mar 12: The Madhya Pradesh Congress on Thursday took a dig at Jyotiraditya Scindia, who broke ranks with the party and joined BJP on Wednesday, by pointing out that neither Prime Minister Narendra Modi nor Amit Shah had not even put out as much a tweet to welcome him in the party, and construed it as "humiliation" for the "maharaja".

"Not even a tweet by Narendra Modi-ji or Amit Shah-ji to welcome Scindia-ji! Modi-ji, Shah-ji, at least do not do it so soon. It has not even been 24 hours yet and you guys have already started humiliating him...!" Madya Pradesh Congress tweeted in Hindi.

Taking a jibe at Mr Scindia, a member of the erstwhile royal family of Gwalior who ended his 18-year-long association with the Congress party on a bitter note, the state Congress said: "He is a maharaja, the one whose history is often mentioned by Shivraj-ji (former Madhya Pradesh Chief Minister Shivraj Singh Chouhan)."

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

Mr Scindia will file his nomination for the Rajya Sabha elections on March 13. He is expected to go to Bhopal today.
