Expressing concern over the ban imposed on TikTok by the government of India, Facebook CEO Mark Zuckerberg has reportedly called the development in the south Asian country “worrisome”.

TikTok was amongst the 59 Chinese apps that were banned in India but why it hogs the maximum limelight because TikTok had the second-largest user base in India with over 200 million users.

As per The Verge writer Casey Newton, Zuckerberg was worried about TikTok’s India ban. Although it soon cashed into the opportunity and released a TikTok clone “Reels”, the government’s reason behind banning the app in India wasn’t received well by Mark Zuckerberg. 

He had said that if India can ban a platform with over 200 million users in India without citing concrete reasons, it can also ban Facebook if something goes amiss on the security and privacy front.

Why Mark finds it particularly worrisome because Facebook is already involved in a lot tussle with the governments across the world involving national security concerns. 

“Facebook already faces fights around the world from governments on both the left and the right related to issues that fit under the broad umbrella of national security: election interference, influence campaigns, hate speech, and even just plain-old democratic speech. Zuckerberg knows that the leap from banning TikTok on national security grounds to banning Facebook on national security grounds is more of a short hop,” the report by Casey read.

Facebook till now has not faced any kind of issue in India but considering the debacle with the other governments, it is not entirely wrong to worry about its future in India if any national security issue arises. Back in 2016, Facebook’s Free Basics service, which means a free but restricted internet service, was banned in India by the telecom regulators. 

The TRAI had said that the Free Basic services were banned in India because it violated the principles of net neutrality. With Free Basics services, Facebook had planned to bring more unconnected users online. But since 2016, there has been no major tussle between the Indian government and Zuckerberg due to national security issues.

New Delhi, Jun 16: The class 10 and 12 students of the CICSE board can choose not to appear for pending board exams and be marked as per their performance in pre-board exams or internal assessment, according to top officials.

The board had also submitted the proposal before the Bombay High Court on Monday in response to a petition filed by a parent seeking directions to the authorities to cancel exams in view of the spike in COVID-19 cases.

According to Gerry Arathoon, Chief Executive and Secretary, Council for the Indian School Certificate Examinations (CISCE), the students will have to communicate their option to their respective schools by June 22.

The exams which were postponed due to the lockdown to contain the spread of coronavirus, are now scheduled to be conducted from July 1 to 14. However, several parents have been demanding the exams be scrapped.

"The students will be given two options---they either appear for the rescheduled exams or choose to have their results based on their performance in the pre-board exams or internal assessment. The option will be available only for the pending exams, the result of the subjects for which exams were already conducted, will be calculated as per performance in the exam only," Arathoon said.

The board also clarified that the students will not be entitled to make a subject-wise choice between the two options for pending exams.

Unlike the Central Board of Secondary Education (CBSE), which will only be conducting exams in 29 subjects crucial for promotion and admission to higher educational institutions, the CISCE will be conducting all pending exams.

The pending CBSE exams are scheduled from July 1 to 15. The schedule for the board exams has been decided in order to ensure that they are completed before competitive examinations. While the engineering entrance exam JEE-Mains is scheduled to be held from July 18 to 23, the medical entrance exam NEET is scheduled for July 26.

While the CBSE has given the option to not appear for pending board exams for differently-abled students, it has canceled the examinations for its around 250 schools situated abroad and has adopted the criteria of awarding marks on the basis of either practical exams conducted or the internal assessment marks.

A group of parents has filed a petition in the Supreme Court seeking a direction to the CBSE to declare results on the basis of tests already conducted, and calculate the total on an average basis with internal assessment marks of the remaining subjects.

Universities and schools across the country have been shut since March 16, when the Centre announced a countrywide classroom shut down as part of measures to contain the COVID-19 outbreak. A nationwide lockdown was announced on March 24, which came into effect the next day.

While the government has eased several restrictions, schools and colleges continue to remain closed.

According to Home Ministry guidelines, there will be no exam centres in containment zones.

"Wearing of face masks by teachers, staff and students will be mandatory. There shall be provisions of thermal screening and sanitiser at the centres and social distancing rules will have to be followed at exam centres. Special buses may be arranged by states and UTs for transportation of students to exam centres," the Home Ministry has said.

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.
