Leaders are feeling suffocated in Cong: Amit Shah asks party to self-introspect

New Delhi, Jun 5: India registered its highest spike in COVID-19 cases with 9,851 more cases and 273 deaths reported in the last 24 hours. The total number of cases in India reached 2,26,770 including 1,10,960 active cases, said the Union Ministry of Health and Family Welfare.

The Ministry informed that 1,09,462 persons have been cured/discharged/migrated while 6,348 people have succumbed to the disease so far.

Maharashtra has so far reported 77,793 cases, more than any other state in the country, while the total number of active cases in the state stands at 41,402.

In Tamil Nadu, 27,256 cases have been detected so far while Delhi has reported 25,004 coronavirus cases.

New Delhi, Mar 5: Retirement fund body EPFO on Thursday lowered interest rate on provident fund deposits to 8.5 per cent for the current financial year, said Labour Minister Santosh Gangwar on Thursday.

The EPFO had provided 8.65 per cent rate of interest on EPF for 2018-19 to its around six crore subscribers. The decision was taken at a meeting of the the Employees' Provident Fund Organisation's (EPFO) apex decision making body -- the Central Board of Trustee.

"The EPFO has decided to provide 8.5 per cent interest rate on EPF deposits for 2019-20 in the Central Board of Trustees (CBT) meeting today," Gangwar told reporters after the meeting here.

Now, the labour ministry requires the finance ministry's concurrence on the matter. Since the Government of India is the guarantor, the finance ministry has to vet the proposal for EPF interest rate to avoid any liability on account of shortfall in the EPFO income for a fiscal.

The finance ministry has been nudging the labour ministry for aligning the EPF interest rate with other small saving schemes run by the government like the public provident fund and post office saving schemes.

The EPFO had provided 8.65 per cent rate of interest to its subscribers for 2016-17 and 8.55 per cent in 2017-18. The rate of interest was slightly higher at 8.8 per cent in 2015-16.

It had given 8.75 per cent rate of interest in 2013-14 as well as 2014-15, higher than 8.5 per cent for 2012-13.

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.
