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.

Aligarh, Jan 14: Uttar Pradesh Minister Raghuraj Singh has courted a major controversy after he said that people who raise slogans against Prime Minster Narendra Modi and Uttar Pradesh Chief Minister Yogi Adityanath "would be buried alive".

The minister said this on Sunday while addressing a rally in Aligarh to muster support for the Citizenship Amendment Act (CAA) 2019.

"If you raise slogans against Prime Minister Narendra Modi or Chief Minister Yogi Adityanath, I will bury you alive," he threatened.

He was apparently referring to protests held by students of Aligarh Muslim University against the CAA during which they allegedly raised slogans against the Prime Minister and the chief minister.

The minister further said: "These one per cent people are opposing the CAA. They stay in India, eat up our taxes and then raise 'murdabad' slogans against the leaders. This country belongs to people of all faiths, but slogan shouting against the Prime Minister or chief minister is unacceptable."

He also launched an attack on India's first Prime Minister Jawaharlal Nehru. "What was Nehru's caste? He did not have a 'khaandan'," he claimed.

Raghuraj Singh is minister of state in the labour ministry in Uttar Pradesh.

New Delhi, Feb 10: The government is set to privatise Central Electronics Ltd, a CPSE under the Department of Science and Technology, by selling its 100% stake with management control and has invited the Expression of Interest for the same by March 16.

The selected bidder will be required to lock in its shares for a period of three years during which it cannot undertake the sale of its stake in CEL, the PIM (Preliminary Information Memorandum) said.

"The government of India has 'in-principle' decided to disinvest 100 per cent of its equity shareholding in CEL (which is equivalent to 100 per cent of the total paid up equity share capital of CEL) through Strategic Disinvestment with transfer of management control (Strategic Disinvestment or Transaction)," DIPAM, the Disinvestment Department, said.

The process for the transaction has been divided into two stages, namely, Stage I and Stage II.

After BPCL and Air India, this is yet another CPSE which government is slated to privatise if it gets offers from bidders.

The government has set a challenging target of Rs 2.1 lakh crore disinvestment proceeds from CPSE sell-offs and IPOs, OFSs (Offer for sale) in the next fiscal and it going out all guns blazing to meet that target after revising this fiscal target of Rs 1.05 lakh crore to Rs 65,000 crore.

The Interested Bidders (which can also include employees of CEL) must have a minimum net worth of Rs 50 crore as on March 2019. DIPAM has released complete invitation Preliminary Information Memorandum (PIM) of CEL. Resurgent India Limited is the advisor to the Transaction.

CEL is a pioneer in the country in the field of Solar Photovoltaic (SPV) with the distinction of having developed India's first Solar cell in 1977 and first Solar panel in 1978 as well as commissioning India's first solar plant in 1992.

More recently, it has developed and manufactured the first crystalline flexible solar panel especially for use on the passenger train roofs in 2015.

Its solar products have been qualified to International Standards IEC 61215/61730. CEL is further working on development of a range of new and upgraded products for signaling and telecommunication in the railway sector.

In the SWOT analysis of the CPSE, DIPAM has stated under weakness that "the company has weak financial loss due to past losses, high manufacturing cost and non payment of dues by state nodal agencies affecting the financial position of the company".

The CPSE has adequate land for expansion, the SWOT analysis said adding "the CPSE faces threat of dumping of solar cells at very low rates which makes solar PV manufacturing industry unviable".

Entry of new players in the market for solar products and railway signalling systems also is cited as a threat.
