‘Modi govt will not tolerate this’: HRD minister to universities against CAA

New Delhi, Jun 8: Union Human Resource Development Minister Ramesh Pokhriyal Nishank has said that CBSE board results can be declared by August 15. The results of both class 10 and 12 will be declared at an interval of just a few days.

However, the decision to open schools will be taken after August keeping in mind the current COVID-19 situation. At present, the Ministry of Human Resource Development has not set any date for reopening schools.

Nishank said during a discussion "We hope that the results of both 10th and 12th class will be declared by August 15. These include the results of previous exams and the results of examinations in July."

On the issue of reopening of schools, Nishank said "after August the process of opening schools will be started."

A final decision in this regard will be taken only after assessing the prevailing conditions. According to the HRD ministry, after August, new sessions will also start in universities.

Meanwhile, the Arvind Kejriwal government in Delhi has also written to the HRD ministry on the subject of reopening schools. Delhi Education Minister Manish Sisodia said in the letter, "Delhi Chief Minister Arvind Kejriwal said some time ago that we have to learn to live with coronavirus. So it would be better to open schools with proper safety measures."

Sisodia said that first of all, we have to assure every child that they are important to us. Everyone has equal rights over the physical and intellectual environment of his school. Education cannot progress beyond online classes only. It would be impossible to pursue education only by calling older children to school and keeping younger children at home.

Several private schools have also suggested measures to the HRD ministry to open schools and safety in schools during this period. However, the ministry is not in a hurry to reopen schools at present. According to senior officials of the ministry, at present, preparations are being made to conduct the remaining board exams of class 10 and 12 between July 1 and 15.

After the examinations, the first priority is to declare the results. Only then can the process of reopening school colleges begin.

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 13: In a significant landmark, the BrihanMumbai Municipal Corporation (BMC) has achieved a doubling-rate of 50 days for COVID-19 cases, a top official said on Monday.

This was possible because of the civic body's 'open testing policy', implying tests without prescriptions, making it the only city in the country to implement it.

"After the open testing policy, our testing has gone up from 4,000 to 6,800, daily. But the total positive cases have come down from 1,400 to 1,200 now," BMC Municipal Commissioner I.S. Chahal told IANS.

Of these 1,200 positive cases, the symptomatic cases are less than 200, so the BMC needs only 200 beds daily, the civic chief said.

Even the BMC's discharge rate now stands at 70 percent, and on Sunday, after allotting beds to all patients, there were still 7,000 COVID beds plus 250 ICU beds lying vacant, said Chahal.

For this achievement, Chahal gave the credit to the entire 'Team BMC' where - despite losing a little over 100 officials to the virus - civic officials and other Corona warriors are engaged 24x7 in controlling the pandemic for over four months.

Since the first case was detected in Mumbai on March 11 (after the state's first infectees in Pune on March 9) and the state's first death notched in Mumbai on March 17, the current Maharashtra Covid-19 tally stands at 2,54,427 cases and fatalities at 10,289, while Mumbai has recorded 92,988 cases with a death toll of 5,288.
