Modi arrives in Russia on 2-day visit

Washington, Feb 21: US President Donald Trump has made yet another tall claim about the size of the crowd that will welcome him in Ahmedabad, saying Prime Minister Narendra Modi has told him that there will 10 million(1 crore) people to greet him on his arrival for his maiden visit to India.

President Trump and First Lady Melania are scheduled to travel to Ahmedabad, Agra and New Delhi on February 24 and 25.

Speaking to reporters at the Joint Base Andrews in Maryland on Tuesday, Trump said that Modi told him that "we'll have 7 million people between the airport and the event."

"So it's going to be very exciting. But he says between the stadium and the airport, we'll have about 7 million people. So it's going to be very exciting. I hope you all enjoy it," he said.

On Thursday, Trump upped the crowd size by three million at a 'Keep America Great' rally in Colorado.

"I hear, they are going to have 10 million people. They say anywhere from six to 10 million people are going to be showing up along the route to one of the largest stadiums in the world, the largest cricket stadium in the world, which is brand new and beautiful," said Trump, who is seeking reelection in the November presidential polls.

But according to a top civic official in Ahmedabad, the total population of the city is only around 70 lakh.

The authorities believe that between one to two lakh people are expected to line up along the 22-km route of the road show by Modi and Trump from the airport to the Motera cricket stadium, said to be the world's largest.

"We believe that around one to two lakh people will gather to welcome the dignitaries during the road show," Ahmedabad Municipal Commissioner Vijay Nehra said on Thursday, contradicting the claims made by the US President.

As per the road show route plan, Trump and Modi will first reach the Sabarmati Ashram, a place closely associated with Mahatma Gandhi, from Ahmedabad airport.

Addressing his supporters, Trump spoke about his India visit and said the "Namaste Trump" rally in Ahmedabad would spoil him.

"Prime Minister Modi said, we will have 10 million people greet you. Here's my problem. We have a packed house. We have a lot of people, thousands of people that couldn't get in. It's going to look like peanuts from now on," he said.

"I'll never be satisfied with the crowd. If we have 10 million people in India, how can I be satisfied when we fill up like a 60,000-seat stadium? I am getting spoiled," Trump said.

One of Trump's supporters from the audience then suggested that he build a bigger stadium.

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, Mar 28: The world is in the face of a devastating impact due to the coronavirus pandemic and has clearly entered a recession, the International Monetary Fund said on Friday, but projected a recovery next year.

"We have reassessed the prospects for growth for 2020 and 2021. It is now clear that we have entered a recession as bad or worse than in 2009. We do project recovery in 2021," IMF Managing Director Kristalina Georgieva told reporters at a news conference.

Georgieva was addressing the press after a meeting of governing body of the IMF, the International Monetary and Financial Committee. Representing 189 members, the body met virtually to discuss the unprecedented challenge posed to the world by COVID-19.

The key to recovery in 2021, she said, is only if the international community succeeds in containing the virus everywhere and prevent liquidity problems from becoming a solvency issue.

"The US is in recession, as is the rest of the advanced economies of the world. And in a big chunk of developed and emerging markets in developing economies. How severe? We are working now on our projections for 2020, Georgieva said in response to a question.

The new projections are expected in the next few weeks.

Stressing that while containment is the main reason for the economy to stand still and get into a recession, she said containment is very necessary to come out of this period and step in to recovery. "Until the virus is not contained, it would be very difficult to go to the lives we love."

"A key concern about a long-lasting impact of the sudden stop of the world economy is the risk of a wave of bankruptcies and layoffs that not only can undermine the recovery. But can erode the fabric of our societies," the IMF chief said.

To avoid this from happening, many countries have taken far-reaching measures to address the health crisis and to cushion its impact on the economy, both on the monetary and on the fiscal side, she said.

The IMF chief said 81 emergency financing requests, including 50 from lower-income countries, have been received. She said current estimate for the overall financial needs of emerging markets is 2.5 trillion dollars.

"We believe this is on the lower end. We do know that their own reserves and domestic resources will not be sufficient," she added.

The G-20, a day earlier, reported fiscal measures totalling some 5 trillion dollars or over 6 per cent of the global GDP.

Responding to another question, Georgieva said the IMF is projecting recession for 2020.

"We do expect it to be quite deep and we are very much urging countries to step up containment measures aggressively so we can shorten the duration of this period of time when the economy is in standstill," she said.

"And also to apply well-targeted measures, primarily focusing on the health system to absorb that enormous stress that comes from coronavirus. And on people, businesses and the financial system, I am very pleased to say that when we went through countries' responses, that sense of targeted fiscal measures is there and are also very impressive to see the size of these measures," she added.

"Countries are doing all they can on the fiscal and on the monetary front. We have heard from our members' very impressive decisions taken over the last days," the IMF chief said.

"We also want to caution that as we are responding now, we want to make the recession as possibly short and not too deep. We also want to think about what is going to follow the recovery and make sure that we are putting forward measures that can be supportive in this regard," she said.
