‘Sardar Patel’s order banning RSS should be displayed at 'Statue of Unity'’

New Delhi, Jul 26: Union Home Minister Amit Shah on Sunday saluted the valour and grit of the Indian soldiers on the occasion of 21st anniversary of the 'Kargil Vijay Diwas'.

Shah took to Twitter and said that 'Kargil Vijay Diwas' is a symbol of India's proud, valour and steadfast leadership.

"Kargil Vijay Diwas is a symbol of India's proud, valor and steadfast leadership. I bow to the soldiers who, with their indomitable courage, drove the enemy from the inaccessible hills of Kargil and waved the tricolor there again. The country is proud of the heroes of India, who are dedicated to protecting the motherland," Shah tweeted (translated from Hindi)
The country is celebrating the anniversary of the 'Kargil Vijay Diwas'.

The Indian armed forces had defeated Pakistan on July 26, 1999. Since then, the day is celebrated as 'Kargil Vijay Diwas' to rekindle the pride and valour of the soldiers who took part in Operation Vijay.

The day marks the victory of Indian soldiers in recapturing the mountain heights that were occupied by the Pakistani Army on July 26, 1999, known as the Kargil War. 

Srinagar, Feb 9: Authorities on Sunday snapped mobile internet services in Kashmir as a precautionary measure to prevent any law and order disturbance on the seventh death anniversary of Parliament attack convict Mohammad Afzal Guru, officials said.

The mobile internet services were suspended early in the morning as the authorities apprehended violence in the valley in view of the bandh call given by separatist outfits, the officials said.

The authorities had restored 2G internet services in Kashmir on January 25, more than five months after snapping all communication facilities in the valley following abrogation of Article 370 on August 5 last year.

Police on Saturday lodged an FIR against the banned Jammu Kashmir Liberation Front (JKLF) for calling a strike on Afzal Guru's death anniversary.

Guru was hanged in 2013 inside Tihar jail for his role in the Parliament attack in December 2001.

Two journalists were summoned by police for reporting the JKLF press release, which had called for strike on Sunday and Tuesday -- the death anniversary of the outfit founder Mohammad Maqbool Bhat.

They were let off after five hours of questioning. Bhat was hanged in 1984 and is buried inside Tihar jail.

Meanwhile, normal life in Kashmir was affected due to the strike, the officials said.

Markets and business establishments remained closed, while public transport was largely off the roads, they said.

There have been no reports of any untoward incident from anywhere in the valley so far, the officials added.

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.
