PMC Bank crisis: Fourth death 83-year-old unable to pay for surgery

New Delhi, June 13: A quarantine notice pasted outside former Prime Minister Manmohan Singh’s 3, Motilal Nehru Place residence has raised speculations among media and political circles.

According to reports, the daughter of a domestic help who works at Singh’s residence has tested positive. She and her family, who live in the servant quarters, have been quarantined.

Singh, who has not been keeping well for some time, is slowly getting active. Congress leaders said the former Prime Minister attended a meeting of the party’s consultative committee on Thursday through video conference.

Hyderabad, Apr 12: Indicating that prolonged lockdown to contain coronavirus spread may lead to job cuts in the Indian IT industry, NASSCOM former president R Chandrashekhar has said that the work-from-home culture may become a positive development in the long run as it opens up newer avenues and save investments by IT firms.

The former bureaucrat also said startups which are surviving on funds infused by venture capitalists may face tougher situations if the present scenario deteriorates.

"The larger companies may not be actually cutting jobs for two reasons. One is that they do not want to lose their employees and they have money to pay. Many of them ( big companies), even if they do shed some jobs it might be at the most people who are on temporary or intern type and all. But they would not want regular and permanent employees to go. So as long as they have sufficient flexibility in their books, they would continue," said NASSCOM former president.

"But beyond a point that it goes on, for let us say, two months or three months, then even for them, they will feel the pressure. They may not just keep on providing subsidies to the employees. So the key question will be how long that goes on," Chandrasekhar said.

He also said the work-from-home systems being adopted by several firms across the globe, including India, may have a negative impact on the industry in the short-term, but in the long run it would change the work culture which hitherto was not experienced by many of the IT firms in India.

 On impact of the prolonged lockdown on startups, he said it would be a big challenge for the budding enterprises as the investments they get are based on their ideas and future revenues and the present situation under which peoples movement is curbed may shackle their progress.

 "Where will they (startups) get money to pay salaries to their employees. Venture capital investors would not pay the money or invest their money to pay salaries because they are not in the charity business."

If the employees are not paid and if they leave and it is difficult for the startup againto come up. So the whole investment plan goes for a toss, he said.

Former chairman of NASSCOM, B V R Mohan Reddy said a clear picture as to what is going to happen has not yet emerged as the situation with all respects is still evolving. Reddy said there will be a demand shrinkage for the IT industry as the entire world is under stress. "There is no economy in this world that is going to do well in this situation.

So, therefore, there will be a demand shrinkage, he said, indicating tougher times of the industry ahead.

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.
