IAS officer’s body found near tracks; will jump off building, says death note

Feb 28: The best economic tonic for the coronavirus shock is to contain its spread and worry about stimulus later, said Raghuram Rajan, former head of the Reserve Bank of India.

There’s little central banks can do, and while more government spending would help, the priority should be on convincing companies and households that the virus is under control, he said.

“People want to have a sense that there is a limit to the spread of this virus perhaps because of containment measures or because there is hope that some kind of viral solution can be found,” Rajan told Bloomberg Television’s Haidi Stroud Watts and Shery Ahn.

“At this point I would say the best thing that governments can do is to really fight the epidemic rather than worry about stimulus measures that comes later,” said Rajan, who is currently a professor at the Chicago Booth School of Business.

The spread of coronavirus is pushing the world economy toward its worst performance since the financial crisis more than a decade ago.

Bank of America Corp. economists warned clients Thursday that they now expect 2.8% global growth this year, the weakest since 2009.

“We have moved from extreme confidence in markets to extreme panic, all in the space of one week,” said Rajan, who previously was chief economist at the International Monetary Fund.

The virus outbreak will force companies to rethink supply chains and overseas production facilities, he said.

“I think we will see a lot of rethinking on this, coming on the back of the trade disruption, now we have this,” Rajan said. “Globalization in production is going to be hit quite badly.”

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.

Mumbai, Jul 14: Bhima Koregaon case accused Varavara Rao was admitted to JJ Hospital in Mumbai on Monday night.

Rao who is in Taloja proson was rushed to the hospital following complaint of dizziness.

Rao was arrested in November 2018 along with five others, for alleged links with Naxals and for inciting the violence.

On January 1, 2018, the violence at Bhima Koregaon village in Pune district left one dead and several others injured including 10 policemen.

Violence erupted after some people, reportedly with saffron flags, pelted stones at cars heading towards the village for the commemoration of 200 years of Bhima-Koregaon war on New Year's Day.

The police had filed 58 cases against 162 people.
