2-yr-old TN boy trapped in abandoned borewell for 3 days found dead

Aurangabad, Apr 4: A marriage was solemnised on a video call, the unique method which was adopted due to coronavirus lockdown.

A Muslim man named Mohammad Minhajudd, based in Aurangabad exchanged marriage vows with a Muslim woman based in Beed via video call on Friday.

The entire country is witnessing a 21-day lockdown due to which there is a limitation on the movement of people from one place to another and gatherings have been banned to prevent the spread of the coronavirus that has wreaked havoc across the globe.

The marriage halls are also closed during the lockdown period.

The bridegroom's father Mohammad Gayaz said that the marriage was fixed between the two persons six months ago when there was no fear about coronavirus. We got the elders of the family assembled at our home and conducted the marriage on phone.

Mufti Anis ur Rehman, the Qazi who performed the rituals for the marriage, said that both the families are happy as the marriage got conducted with the minimal cost incurred and the ceremony was a simple one. 

Mumbai, Mar 27: The RBI on Friday put on hold EMI payments on all term loans for three months and cut interest rate by steepest in more than 11 years as it joined the government effort to rescue a slowing economy that has now got caught in coronavirus whirlwind.

The Reserve Bank of India (RBI) cut repo to 4.4 per cent, the lowest in at least 15 years. Also, it reduced the cash reserve ratio maintained by the banks for the first time in over seven years. CRR for all banks was cut by 100 basis points to release Rs 1.37 lakh crore across banking system.

The reverse repo rate was cut by 90 bps to 4 per cent, creating an asymmetrical corridor.

RBI Governor Shaktikanta Das predicted a big global recession and said India will not be immune.

It all depends how India responds to the situation, he said.

Global slowdown could make things difficult for India too, despite some help from falling crude prices, Das said, adding food prices may soften even further on record crop production.

Aggregate demand may weaken and ease core inflation further, he noted.

The liquidity measures announced include auction of targeted long-term repo operation of 3 year tenor for total amount of Rs 1 lakh crore at floating rate and accommodation under Marginal Standing Facility to be increased from 2 per cent to 3 per cent of Statutory Liquidity Ratio (SLR) with immediate effect till June 30.

Combined, these three measures will make available a total Rs 3,74,000 crore to the country's financial system.

After cutting policy rates five times in 2019, the RBI had been on a pause since December in view of high inflation.

The measures announced come a day after the government unveiled a Rs 1.7 lakh crore package of free foodgrains and cash doles to the poor to deal with the economic impact of the unprecedented 21-day nationwide lockdown.

While the Monetary Policy Committee (MPC) of the RBI originally was slated to meet in the first week of April, it was advanced by a week to meet the challenge of coronavirus.

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.
