London: PM Modi says, Indians have become more aspirational under his rule

New Delhi, Feb 11: Senior Delhi Congress leader and national spokesperson of the party Sharmishtha Mukherjee alleged delay in decision making and lack of strategy and unity at the state level for the party's humiliating performance reflected in the Assembly poll results on Tuesday.

Mukherjee, president of Delhi Mahila Congress, stated that it was high time that the party takes some action. She added that she too was responsible for the Congress' poor show.

The Congress is on the verge of drawing blank again in the Assembly polls as all its candidates were way far behind their AAP and BJP opponents on all the 70 seats. In the 2015 Assembly elections too, Congress failed to win any seat.

"We r again decimated in Delhi. Enuf of introspection, time 4 action now. Inordinate delay in decision making at the top, lack of strategy & unity at state level, demotivated workers, no grassroots connect-all r factors. Being part of d system, I too take my share of responsibility (sic)," Mukherjee tweeted as the results came out.

She also accused the BJP of playing divisive politics while crediting Delhi Chief Minister Arvind Kejriwal for playing "smart politics" as the results showed a clean sweep by the AAP to return to power.

"BJP playing divisive politics, Kejriwal playing ‘smart politics’ & what r we doing? Can we honestly say that we’ve done all 2 put our house in order? We r busy capturing Congress whereas other parties are capturing India. If we r 2 survive, time 2 come out of exalted echo chambers! (sic)," she said in another tweet.

The Congress contested the Delhi polls in alliance with the Rashtriya Janta Dal (RJD), fielding candidates on 66 seats and leaving four to its partner.

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.

Washington, Feb 22: US President Donald Trump will raise the issue of religious freedom with Prime Minister Narendra Modi during his visit to India next week, the White House said on Friday, noting that the US has great respect for India's democratic traditions and institutions.

"President Trump will talk about our shared tradition of democracy and religious freedom both in his public remarks and then certainly in private. He will raise these issues, particularly the religious freedom issue, which is extremely important to this administration," a senior official told reporters in a conference call.

The official was responding to a question on whether the president was planning to speak to Modi on the Citizenship (Amendment) Act or the National Register of Citizens.

"We do have this shared commitment to upholding our universal values, the rule of law. We have great respect for India's democratic traditions and institutions, and we will continue to encourage India to uphold those traditions," the official said, requesting anonymity.

"And we are concerned with some of the issues that you have raised," the senior administration official said, in response to the question on CAA and NRC.

"I think the President will talk about these issues in his meetings with Prime Minister Modi and note that the world is looking to India to continue to uphold its democratic traditions, respect for religious minorities," the official said.

"Of course, it's in the Indian constitution -- religious freedom, respect for religious minorities, and equal treatment of all religions. So this is something that is important to the president and I'm sure it will come up," said the official.

Pointing out that India has a strong democratic foundation, the official said India is a country rich in religious, linguistic, and cultural diversity.

"In fact, it's the birthplace of four major world religions," the official noted.
