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, May 12: Former Prime Minister Manmohan Singh, who was admitted to the AIIMS here after suffering reaction to a new medication, was discharged on Tuesday.

The 87-year-old Congress leader was discharged around 12:30 pm, hospital sources said.

Manmohan Singh was shifted to a private ward in the Cardio-Neuro tower on Monday night. He was also tested for Covid-19 and his results had come out negative, the sources said. The Congress leader was admitted to the hospital on Sunday evening after he complained of uneasiness.

The sources said that Singh had developed a reaction to a new medication and was admitted to AIIMS for observation and investigation.

Manmohan Singh is currently a Member of Rajya Sabha from Rajasthan. He was the prime minister between 2004 and 2014.

In 2009, Singh underwent a successful coronary bypass surgery at the AIIMS.

London, Feb 14: Liquor tycoon Vijay Mallya once again asked the Indian banks to take back 100 per cent of the principal amount owed to them at the end of his three-day British High Court appeal on Thursday against an extradition order to India.

The 64-year-old former Kingfisher Airlines boss, wanted in India on charges of fraud and money laundering amounting to an alleged Rs 9,000 crores in unpaid bank loans, said the Enforcement Directorate (ED) and the Central Bureau of Investigation (CBI) are fighting over the same assets and not treating him reasonably in the process.

“I request the banks with folded hands, take 100 per cent of your principal back, immediately,” he said outside the Royal Courts of Justice in London.

“The Enforcement Directorate attached the assets on the complaint by the banks that I was not paying them. I have not committed any offenses under the PMLA (Prevention of Money Laundering Act) that the Enforcement Directorate should suo moto attach my assets," he said.

"I am saying, please banks take your money. The ED is saying no, we have a claim over these assets. So, the ED on the one side and the banks on the other are fighting over the same assets,” he added.

Asked about heading back to India, he noted: “I should be where my family is, where my interests are.

"If the CBI and the ED are going to be reasonable, it’s a different story. What all they are doing to me for the last four years is totally unreasonable.”

Lord Justice Stephen Irwin and Justice Elisabeth Laing, the two-member bench presiding over the appeal, concluded hearing the arguments in the case and said they will be handing down their verdict at a later date after considering the oral as well as written submissions in the “very dense” case over the next few weeks.

On a day of heated arguments between Mallya’s barrister, Clare Montgomery, and Crown Prosecution Service (CPS) counsel Mark Summers, arguing on behalf of the Indian government, both sides clashed over the prima facie case of fraud and deception against Mallya.

“We submit that he lied to get the loans, then did something with the money he wasn’t supposed to and then refused to give back the money. All this could be perceived by a jury as patently dishonest conduct,” said Summers.

“What they [Kingfisher Airlines] were saying [to the banks] about profitability going forward was knowingly wrong,” he said, as he took the High Court through evidence to counter Mallya’s lawyers’ claims that Westminster Magistrates Court Judge Emma Arbuthnot had fallen into error when she found a case to answer in the Indian courts against Mallya.

Mallya, who remains on bail on an extradition warrant, is not required to attend the hearings but has been in court to observe the proceedings since the three-day appeal opened on Tuesday. A key defence to disprove a prima facie case of fraud and misrepresentation on his part has revolved around the fact that Kingfisher Airlines was the victim of economic misfortune alongside other Indian airlines.

However, the CPS has argued that “there is enough in the 32,000 pages of overall evidence to fulfil the [extradition] treaty obligations that there is a case to answer”. “There is not just a prima facie case but overwhelming evidence of dishonesty… and given the volume and depth of evidence the District Judge [Arbuthnot] had before her, the judgment is comprehensive and detailed with the odd error but nothing that impacts the prima facie case,” said Summers.

At the start of the appeal, Mallya’s counsel claimed Arbuthnot did not look at all of the evidence because if she had, she would not have fallen into the multiple errors that permeate her judgment. The High Court must establish if the magistrates’ court had in fact fallen short on a point of law in its verdict in favour of extradition.

Representatives from the Enforcement Directorate (ED) and Central Bureau of Investigation (CBI), as well as the Indian High Commission in London, have been present in court to take notes during the course of the appeal hearing.

Mallya had received permission to appeal against his extradition order signed off by former UK home secretary Sajid Javid last February only on one ground, which challenges the Indian government's prima facie case against him of fraudulent intentions in acquiring bank loans.

At the end of a year-long extradition trial at Westminster Magistrates’ Court in London in December 2018, Judge Arbuthnot had found “clear evidence of dispersal and misapplication of the loan funds” and accepted a prima facie case of fraud and a conspiracy to launder money against Mallya, as presented by the CPS on behalf of the Indian government.

Mallya remains on bail since his arrest on an extradition warrant in April 2017 involving a bond worth 650,000 pounds and other restrictions on his travel while he contests that ruling.
