BJP's Kerala unit chief Rajasekharan sworn in as Mizoram Governor

New Delhi, Feb 25: Union Home Minister Amit Shah on Tuesday called a meeting to discuss the prevailing situation in the national capital after violence in Northeast Delhi over the amended citizenship law left four people dead.

Delhi's Lieutenant Governor Anil Baijal, Chief Minister Arvind Kejriwal and representatives of different political parties were invited for the meeting.

The home minister has convened a meeting to discuss the current situation in Delhi, a Home Ministry official said.

The move came after the home minister reviewed the law and order situation in the national capital on Monday night as violence rocked Northeast Delhi.

Frenzied protesters torched houses, shops, vehicles and a petrol pump, besides hurling stones.

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, June 27: The Prime Minister Narendra Modi-led union government of India is not ready to stop all imports from aggressive China in spite of mount calls to boycott Chinese products in India.

The Centre is reportedly considering to stop only non-essential imports from the neighbouring country.

However, the Inward shipment in sectors such as automobiles, pharmaceuticals, certain electronics and others will continue until a domestic alternative is found.

“India will gradually move towards import substitution. It will not happen overnight. In the meantime, attention has to be paid on production and job creation. We cannot throttle our industry. There are certain absolutely essential imports. Needless to say, those will keep going,” official sources said.

Sources said that both the government and the industry are in the process of identifying products that can be domestically manufactured in the medium term. There are certain chemicals, automotive components, handicrafts, cosmetics, agriculture items and certain consumer electronics, which can be manufactured domestically in the short to medium term. The government is doing all it can to raise the capacity of domestic industries.

However, there are certain other imports in the automobile and the pharmaceutical sectors which cannot be done away within the short to medium term. Their domestic production at the moment may not be that cost-effective.

The six-crore strong traders’ body CAIT has been at the forefront of such a demand and has launched a campaign to celebrate Indian Diwali this year with a total absence of Chinese goods.

“Ease of doing business, capital availability at lower rates and globally competitive logistics and energy costs are some of the prerequisites that the government should look into to ensure the growth of the domestic auto component industry,” according to Automotive Component Manufacturers Association of India (ACMA) Director General Vinnie Mehta.

Maruti Suzuki Chairman R C Bhargava said, “People who are boycotting Chinese goods have to remember that in some cases it may lead to their being asked to pay more for the same product."

Meanwhile, domestic rating agency Acuite Ratings & Research has analysed the current import portfolio from China and found 40 sub-sectors have the potential to lower their import dependency on China. These sectors contribute to $33.6 billion worth of imports from China and about 25% of these imports can be substituted by local manufacturing without any significant additional investments.
