Rupee slips to new low: touches 71.75 against US dollar; 19.53 against UAE dirham

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.

New Delhi, Mar 6: Shares of YES Bank and State Bank of India came under huge selling pressure on Friday as developments unfolded regarding SBI picking stake in the private lender. Shares of the lender hit record low of Rs 5.55, plunging 85 per cent, and were trading below its previous low of Rs 8.16 hit on March 9, 2009.

SBI, on the other hand, slumped 11 per cent to Rs 257.35 on the BSE. The benchmark S&P BSE Sensex was trading with a cut of over 3 per cent at 37,251.37 level.

In the past three months, share price of the private lender has plunged 41 per cent, while the state-owned lender has slipped 14 per cent. In comparison, the S&P BSE Sensex has dipped 5.6 per cent till Thursday.

On Thursday, the Reserve Bank of India superseded the board of troubled private sector lender YES Bank and imposed a 30-day moratorium on it “in the absence of a credible revival plan” amid a “serious deterioration” in its financial health.

During the moratorium, which came into effect from 6 pm on Thursday, YES Bank will not be allowed to grant or renew any loans, and “incur any liability”, except for payment towards employees’ salaries, rent, taxes and legal expenses, among others.

This is the first time that a bank of this size will be put under a moratorium by the RBI.

“The financial position of YES Bank had undergone a steady decline “largely due to inability of the bank to raise capital to address potential loan losses and resultant downgrades, triggering invocation of bond covenants by investors, and withdrawal of deposits,” RBI said in a statement.

“After the moratorium, the next step will be to infuse to money and keep the bank afloat. So from shareholders’ point of view, the future is certainly hazy as the capital requirement is huge. The good part, however, is that the RBI has stepped in and depositors don't have to worry,” says Siddharth Purohit, a research analyst at SMC Securities.

Meanwhile, analysts at Nomura believe that placing the Bank under moratorium implies that equity value in the bank would be negligible, and that the chances of private capital participating in future capital raising plan are near zero.

"Any resolution for Yes Bank is more proposed from the perspective of deposit holders and systemic stability, and not from the perspective of Yes Bank equity investors or even perpetual bond holders," they wrote in a note dated March 6.

In another development, SBI’s Board Thursday gave in-principle approval to consider an “investment opportunity” in YES Bank, even as it said “no decision had yet been taken to pick up stake in the bank”.

According to a  report, highly-placed sources indicated a rescue plan involving SBI and Life Insurance Corporation of India (LIC) was being discussed and an announcement in this regard might be made soon.

“While the finer details of the deal are being worked out, it is anticipated that both SBI and LIC together will take a 51 per cent stake in the bank, with a one-year lock-in period,” the report said.

Most analysts believe it is a positive step for the Indian financial sector as the government has tried to avoid a repeat of IL&FS-like crisis.

“The move is a positive step for the financial sector as a whole. By this, the government has tried to avoid a repeat of IL&FS-like crisis and has saved the depositors,” said AK Prabhakar, Head of Research at IDBI Capital. While we know that YES Bank has a huge pile of bad loans, SBI is the only bank that has the capacity to absorb it, he added.

However, the valuation at which YES bank would be taken over remains a cause of concern.

Global brokerage firm JP Morgan Thursday cut its target price for YES Bank on Thursday to Rs 1 per share, taking into account the potential fall in the lender’s net worth due to stressed assets.

“We believe forced bailout investors will likely want the bank to be acquired at near-zero value to account for risks associated with the stress book and likely loss of deposits. We think the bank will need to be recapitalised at nominal equity value and could test dilution of additional tier 1 (AT1) capital. We remain underweight and cut our target price to Rs 1 as we believe net worth is largely impaired,” JP Morgan said in a note.

Global brokerage firm Nomura estimates a need of Rs 25,000-44,000 crore and adjusted for Rs 7,400 crore of current coverage, if the current stress of Rs 65,000-70,000 crore faces 70 per cent loss given default (LGD).

"It implies Rs 18,000-37,000 crore needed for provisioning against the current net worth of Rs 25,700 crore Also, to run as going concern, the bank would require over Rs 20,000 crore of CET-1 capital as well," the note said.

YES Bank has registered slippages of Rs 12,000 crore so far in FY20, while it has placed Rs 30,000 crore of loan assets under the watch list. Its deposits stood at Rs 2.09 trillion on September 30, 2019, while its advances totalled Rs 2.24 trillion. The bank has delayed publishing its December quarter results by a month to March 14.

New Delhi, Jul 15: Former Rajasthan deputy chief minister Sachin Pilot on Wednesday said that he is "not" joining the Bharatiya Janata Party (BJP).

"I am not joining BJP," said Pilot in a telephonic conversation with ANI.

The comments came a day after he was sacked as Rajasthan deputy chief minister and Pradesh Congress Committee chief by the party.

The decision to sack Pilot was taken yesterday after a CLP meeting at the Fairmont Hotel in Jaipur, Rajasthan.

At the meeting, as many as 102 MLAs unanimously demanded that Pilot should be removed from the party.

The Rajasthan Congress is in turmoil over the past few days. While chief minister Ashok Gehlot has blamed the BJP for attempting to destabilise the state government by poaching MLAs, Pilot has been camping in Delhi.

A controversy broke out in Rajasthan after special operation group (SOG) sent a notice to Pilot to record his statement in the case registered by SOG in the alleged poaching of Congress MLAs in the state.
