Google’s Rs 1.44-cr offer: It’s a mistake, parents tell authorities

New Delhi, May 13: Prime Minister Narendra on Tuesday announced Rs 20 lakh crore special economic package for the country to be 'self-reliant' and deal with COVID-19.

"I announce a special economic package today. This will play an important role in the 'Atmanirbhar Bharat Abhiyan.' The announcements made by the government over COVID, decisions of RBI and today's package totals to Rs 20 lakh crore. This is 10 per cent of India's GDP," said Prime Minister Modi in his address to the nation. The Prime Minister said that humanity would not accept defeat from the coronavirus but the people have to stay safe and move forward.

"We had never seen or heard about such a crisis ever before. This is definitely unimaginable for mankind. It is unprecedented. But humanity will not accept defeat from this virus. We have to not only protect ourselves but also move forward," he said.

Talking about the gravity of the virus, Modi said: "It has been four months the world is fighting COVID-19. More than 42 lakh people from different countries have been infected by COVID-19. More than 2.75 lakh people have lost their lives due to the virus. In India too many families have lost their dear ones, I express my condolences to them."

"Today when the entire world is in crisis, we will have to further firm our resolve," he added.

The Prime Minister on Monday held a video conference meeting with Chief Ministers of all states to discuss the road ahead in India's fight against COVID-19 and noted that he was of the firm view that measures needed during the third phase of lockdown will not be needed in the fourth phase.

Prime Minister Modi had said the need was to reduce the transmission rate of the disease and to increase public activity gradually while adhering to all the guidelines and efforts to be made towards achieving both these objectives.

The phase three of the lockdown is coming to an end on May 17.

Kashmir, Jun 14: An Army personnel was killed and two others were injured as Pakistani troops opened fire and shelled areas along the Line of Control in Poonch district of Jammu and Kashmir, officials said on Sunday.

This is the third fatality in the Pakistani firing and shelling on forward posts and villages in the twin districts of Poonch and Rajouri this month.

The officials said the latest firing and shelling from across the border took place in Shahpur-Kerni sector on Saturday night, drawing strong retaliation by the Indian Army.

Three Indian Army personnel were injured in the Pakistani firing and were immediately evacuated to hospital, where one of them succumbed to injuries, the officials said.

They said the casualties suffered by the Pakistani Army in the retaliatory action were not known immediately.

On June 4, havaldar P Mathiazhagan fell to Pakistani firing in Sunderbani sector of Rajouri district, while on June 10, Naik Gurcharan Singh lost his life in a similar incident in Rajouri sector.

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.
