New Delhi, Jun 7: A day after India and China military commanders held "cordial and positive" talks at Chushul-Moldo point along the Line of Actual Control in Eastern Ladakh, Ministry of External Affairs said the two countries have agreed to "peacefully" resolve the situation in the border areas by continuing the military and diplomatic engagements.

The Indian delegation led by 14 Corps Commander Lt Gen Harinder Singh on Saturday met his Chinese equivalent Maj Gen Liu Lin, who is the commander of South Xinjiang Military Region of the Chinese People's Liberation Army, to address the ongoing tussle in Eastern Ladakh.

In a statement on Sunday, the MEA said that the meeting between the Corps Commander based in Leh and the Chinese Commander took place in a "cordial and positive atmosphere".

"Both sides agreed to peacefully resolve the situation in the border areas in accordance with various bilateral agreements and keeping in view the agreement between the leaders that peace and tranquillity in the India-China border regions is essential for the overall development of bilateral relations," the statement read.

They also noted that this year marked the 70th anniversary of the establishment of diplomatic relations between the two countries and agreed that an early resolution would contribute to the further development of the relationship.

"Accordingly, the two sides will continue the military and diplomatic engagements to resolve the situation and to ensure peace and tranquillity in the border areas," it further read.

China has moved its troops along the Line of Actual Control (LAC) in the Eastern Ladakh areas including the Finger area, Pangong Tso Lake, and Galwan Nala area.

The meeting between military commanders was to discuss and resolve the stand-off in Eastern Ladakh.

Following the meeting, the Army Headquarters' Directorate General of Military Operations also briefed the Ministry of External Affairs and other concerned government officials about the discussions.

On Friday, officials of India and China interacted through video-conferencing with the two sides agreeing that they should handle "their differences through peaceful discussion" while respecting each other's sensitivities and concerns and not allowing them to become disputes in accordance with the guidance provided by the leadership.

In the last few days, there has not been any major movement of the PLA troops at the multiple sites where it has stationed itself along the LAC opposite Indian forces.

The Chinese Army's intent to carry out deeper incursions was checked by the Indian security forces by quick deployment.

The Chinese have also brought in heavy vehicles with artillery guns and infantry combat vehicles in their rear positions close to the Indian territory.

New Delhi, Jul 8: India has reported a spike of 22,752 COVID-19 cases in the last 24 hours, taking the country's coronavirus tally to 7,42,417 on Wednesday, informed the Union Ministry of Health and Family Welfare.

Out of the total cases reported, 4,56,830 patients have been cured/discharged from the disease while one patient has been migrated, the Health Ministry informed.

It added that there are 2,64,944 active cases in the country.

482 deaths reported in the last 24 hours due to COVID-19 in the country, taking India's death toll to 20,642.

According to the Union Health Ministry, Maharashtra continues to be the worst affected state reporting 2,17,121 coronavirus cases and 9,250 fatalities.

Tamil Nadu -- the second worst-affected state from COVID-19 -- has a total of 1,18,594 cases and 1,636 deaths due to coronavirus.

While Delhi has a total of 1,02,831 COVID-19 cases including 3,165 deaths.

The Indian Council of Medical Research on Wednesday informed that a total of 1,04,73,771 samples tested for COVID-19 up to July 7. Of these, 2,62,679 samples were tested on Tuesday.

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.
