Triple Talaq verdict: Centre won't rush to enact a new law

New Delhi, Mar 4: The Supreme Court on Wednesday revoked the ban of cryptocurrency imposed by the Reserve Bank of India (RBI) in 2018.

Pronouncing the verdict, the three-judge bench of the apex court said the ban was 'disproportionate'.

The bench included Justice Rohinton Fali Nariman, Justice S Ravindra Bhat and Justice V Ramasubramanian.

The Internet and Mobile Association of India (IAMAI), whose members include cryptocurrency exchanges, and others had approached the top court objecting to a 2018 RBI circular directing regulated entities to not deal with cryptocurrencies.

Advocate Ashim Sood, appearing for IAMI, submitted that Reserve Bank of India lacked jurisdiction to forbid dealings in cryptocurrencies. The blanket ban was based on an erroneous understanding that it was impossible to regulate cryptocurrencies, Sood submitted.

The petitioners had argued that the RBI's circular taking cryptocurrencies out of the banking channels would deplete the ability of law enforcement agencies to regulate illegal activities in the industry.

IAMAI had claimed the move of RBI had effectively banned legitimate business activity via the virtual currencies (VCs).

The RBI on April 6, 2018, had issued the circular that barred RBI-regulated entities from "providing any service in relation to virtual currencies, including those of transfer or receipt of money in accounts relating to the purchase or sale of virtual currencies".

Gurugram, Jul 12: Union Home Minister Amit Shah on Sunday said that the whole world was appreciating India's successful fight against the COVID-19 pandemic.

Speaking ahead of the mega tree plantation drive of the Central Armed Police Forces (CAPFs) at the Central Reserve Police Force (CRPF) Officers' Training Academy in Kadarpur village here, the Home Minister also lauded the contribution of security forces in the battle against COVID-19 in the country.

"India is one of the most populous countries. Everyone thought how will a country like India battle COVID-19, there were apprehensions but today the whole world is witnessing how one of the most successful battles against COVID-19 has been fought here," the Home Minister said.

"In India's battle against COVID-19, all of our security forces are playing a huge role, nobody can deny it. Today, I salute these corona warriors. They have proved that they not only know how to fight terrorism but also against COVID with help of people," he added.

The Union Home Minister said that many jawans have given up their lives during the COVID-19 crisis phase and paid tributes to them.

"I have talked to families of those jawans and today once again I thank them, your sacrifice will not go waste. Whenever the history of the human race's fight against COVID-19 is written, the contribution of India's security forces will be mentioned in golden ink," he said.

He also hailed the plantation drive and said that trees planted today should be taken care of by the jawans till they reach maturity, he added the trees chosen for plantation today consisted mostly those which had a long life and would help the generations to come.

Together the CAPFs have targeted to plant around 10 lakh tree saplings across the country today. Heads of all the CAPFs or their representatives were present in the event held at Gurugram. 

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.
