SC dismisses BJP leader’s PIL challenging minority status of Muslims, 4 other communities

Dehradun, Jan 6: Universities are centres of learning and will not be allowed to become "addas" of politics, HRD Minister Ramesh Pokhriyal 'Nishank' has said.

The minister was replying to questions from reporters in Haldwani on Sunday about protests against the amended Citizenship Act across university campuses.

"Universities are centres of learning where the country's future is in the making. We cannot let them become addas of politics," Nishank said.

He accused the opposition parties of trying to turn the universities into hotbeds of politics.

The new legislation passed by Parliament aims to grant citizenship to persecuted religious minorities from Pakistan, Bangladesh and Afghanistan who had taken refuge in India and there is nothing wrong in it, the Union Minister said

"When Pakistan was created, the population of religious minorities there stood at 22 per cent. Today it is a minuscule 3.7 per cent. Persecuted on the basis of their religion, they sought sanctuary in India. The CAA is meant only to grant them citizenship," he said.

Terming the law humanitarian, the minister said it was going to make no difference to the status of Muslims in India and wondered why the Congress was making such a hue and cry about it.

Nishank's press conference in Haldwani was part of the BJP's campaign to create awareness in favour of the amended Citizenship Act.

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.

New Delhi, Jul 9: The Central Board of Secondary Education has strongly defended its decision to drop topics like democratic rights, citizenship, federalism, secularism etc in the name of reducing the syllabus for Classes 9 to 12 due to COVID-19 pandemic. 

The board has claimed that the dropped lessons "are either being covered by the rationalised syllabus or in the Alternative Academic Calendar of NCERT".

The CBSE said it had to come up with the clarification after realizing its decision was "interpreted differently".

"The rationalisation of syllabus up to 30 per cent has been undertaken by the Board for nearly 190 subjects of class 9 to 12 for the academic session 2020-21 as a one-time measure only. The objective is to reduce the exam stress of students due to the prevailing health emergency situation and prevent learning gaps," it said.

While it has said that no questions can be asked from the reduced syllabus in the next board exams, the CBSE has also directed schools to follow alternative calendars prepared by the NCERT.

"Therefore each of the topics that have been wrongly mentioned in media as deleted have been covered under Alternative Academic Calendar of NCERT which is already in force for all the affiliated schools of the Board," it clarified.

On Wednesday, West Bengal CM Mamata Banerjee tweeted: "Shocked to know that the central Government has dropped topics like citizenship, federalism, secularism and partisan in the name of reducing CBSE course during the COVID crisis."

"We strongly object to this and appeal the HRD Ministry to ensure these vital lessons aren't curtailed at any cost," Banerjee added.
