Kerala CM hails Army's plan to induct women in military police

Bengaluru, Apr 19: As many as 25 new cases of coronavirus have been reported in the State till now, said Karnataka's Health Department.

"25 new COVID-19 cases reported in the State from 5 pm Friday to 5 pm on Saturday. The total number of positive cases in the State is 384 including 14 deaths and 104 discharges," added the Health Department.

The Health Department has appealed to the doctors, who are willing to volunteer in the fight against coronavirus, to reach out to the government.

A total of 14,378 COVID-19 cases have been confirmed in the country so far, with 480 deaths being reported due to the virus.

Mumbai, Mar 4: BJP leader Devendra Fadnavis on Tuesday said Maharashtra Chief Minister Uddhav Thackeray should not give "vague" replies on the 5 per cent Muslim quota issue and declare "with courage" that his government will not bring law granting reservation to the minority community.

Mr Fadnavis made the remark after Mr Thackeray, during a press conference earlier in the day, said he has not yet received the proposal regarding giving quota to Muslims and that the Shiv Sena-led government is yet to take any decision on it.

Mr Thackeray made the comments after Maharashtra Minority Affairs Minister Nawab Malik recently said in the legislative council that thestate government will provide 5 per cent quota to Muslims in education.

Mr Malik, an NCP leader, had also said the state government will ensure that a legislation to this effect is passed soon.

The NCP and the Congress, both proponents of Muslim quota, are constituents of the Sena-led Maha Vikas Aghadi government.

Asked about Mr Thackeray's remarks on the issue, Mr Fadnavis said instead of making comments at the press conference, the chief minister should make a statement in the legislature which is currently having its budget session.

The Leader of the Opposition in the assembly said that Mr Malik's opinion is the official position of the government as the minister had talked about giving quota in the council.

"So, instead of making vague comments in the press conference, the chief minister should say in the council that it is not his view (the one expressed by chief minister).

"The chief minister gave vague answers during the press conference, saying the proposal has not come to him. Your minister (Malik) only has said it," Mr Fadnavis told reporters outside the legislature building complex.

The BJP leader maintained there is no provision in the Constitution for religion-based reservation in government jobs or education.

"Say with courage that you will not give the quota, that the Constitution doesn't accept quota based on religion. Hence, we (the government) will not bring law granting quota," the former Chief Minister said.

Mr Fadnavis claimed that if given within the 50 per cent ceiling set by the Supreme Court, the Muslim quota will affect the existing reservation granted to OBCs.

"And if given outside it, it will affect Maratha quota," he added.

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.
