Bahrain may ink pact with India for space tech cooperation

Lukung, Jul 17: Union Defence Minister Rajnath Singh on Friday assured that not an inch of our land can be taken by any power in the world while he interacted with the Indian Army and ITBP personnel at Lukung.

Referring to the India-China border standoff, he said, "Talks are underway to resolve the border dispute but to what extent it can be resolved I cannot guarantee. I can assure you, not one inch of our land can be taken by any power in the world."

Emphasising on finding a diplomatic solution to the standoff, he further said, "If a solution can be found by talks, there is nothing better."
"Recently what happened between troops of India and China at PP14, how some of our personnel sacrificed their lives protecting our border. I am happy to meet you all but also saddened because of their loss. I pay my tributes to them," he added.

Singh interacted with the Army and Paramilitary troops here along with Chief of Defence Staff General Bipin Rawat and Army Chief General MM Naravane.

Earlier today, the Defence Minister witnessed para dropping and scoping weapons here. He also inspected a Pika machine gun.

Indian Army T-90 tanks and BMP infantry combat vehicles carried out the exercise at Stakna, Leh in presence of Singh, Chief of Defence Staff and Army Chief.

Defence Minister is on a two-day visit to Ladakh and Jammu and Kashmir. He will take stock of the situation at both the Line of Actual Control (LAC) and the Line of Control (LOC).

While Pakistan constantly violates ceasefire from across the LoC, China has continued to intrude into Indian territory in Ladakh region in recent past, escalating tensions between India and its eastern neighbour.

On June 15, twenty Indian soldiers laid out their lives during combat with Chinese forces in Galwan valley, leading to tensions between both nations. Chinese soldiers subsequently started moving back following dialogues between two countries through the military level and diplomatic level.

Singh was accompanied by the Chief of Defence Staff General Bipin Rawat and Army Chief General MM Naravane.

Washington, Jul 7: The US military "will continue to stand strong” in relationship to a conflict between India and China or anywhere else, a top White House official said on Monday, after the navy deployed two aircraft carriers to the South China Sea to boost its presence in the region.

"The message is clear. We're not going to stand by and let China or anyone else take the reins in terms of being the most powerful, dominant force, whether it's in that region or over here,” White House Chief of Staff Mark Meadows told Fox News.

“And the message is clear. Our military might stands strong and will continue to stand strong, whether it's in relationship to a conflict between India and China or anywhere else,” Meadows said in response to a question.

He was told that India banned Chinese apps because Indian soldiers were killed by Chinese troops last month and asked what's mission of the two aircraft carriers - the Ronald Reagan and the Nimitz - and what's America's mission.

The troops of India and China are locked in an eight-week standoff in several areas in eastern Ladakh including Pangong Tso, Galwan Valley and Gogra Hot Spring. The situation deteriorated last month following the Galwan Valley clashes that left 20 Indian Army personnel dead as the two sides significantly bolstered their deployments in most areas along the LAC.

The Chinese military on Monday began withdrawing troops from the Galwan Valley and Gogra Hot Spring after National Security Advisor Ajit Doval and Chinese Foreign Minister Wang Yi held lengthy talks on Sunday. Doval and Wang are also the special representatives on the India-China boundary talks.

The United States has sent two of its aircraft carriers to the South China Sea. “Our mission is to make sure that the world knows that we still have the preeminent fighting force on the face of the globe,” Meadows said.

President Donald Trump has invested more in the US military, more in not only the hardware, but the men and women who serve so sacrificially each and every day, he said. “He (Trump) continues to do so,” he added.

China is engaged in hotly contested territorial disputes in both the South China Sea and the East China Sea. Beijing has built up and militarised many of the islands and reefs it controls in the region. Both areas are stated to be rich in minerals, oil and other natural resources and are vital to global trade.

China claims almost all of the South China Sea. Vietnam, the Philippines, Malaysia, Brunei and Taiwan have counter claims over the area.

Appearing on the same Fox News on Monday talk show with host Brian Kilmeade, influential Republican Senator Tom Cotton said that the US aircraft carriers are headed to the South China Sea to thwart off any Chinese misadventure against Taiwan or other countries in the region.

"That's one of the reasons why we have those aircraft carrier groups in the South China Sea. I mean, look what China did in the southwest. It's essentially invaded India over the last few weeks and killed Indian soldiers,” Cotton said.

"No country on China's periphery, right now, is safe from Chinese aggression. All those countries want a close relationship with the United States. We ought to have one,” Cotton said.

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.
