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.

Jun 23: US President Donald Trump has issued a proclamation to suspend issuing of H-1B visas, which is popular among Indian IT professionals, along with other foreign work visas for the rest of the year.

Trump said the step was essential to help millions of Americans who have lost their jobs due to the current economic crisis.

Issuing the proclamation ahead of the November presidential elections, Trump has ignored the mounting opposition to the order by various business organisations, lawmakers and human rights bodies.

The proclamation that comes into effect on June 24, is expected to impact a large number of Indian IT professionals and several American and Indian companies who were issued H-1B visas by the US government for the fiscal year 2021 beginning October 1.

They would now have to wait at least till the end of the current year before approaching the US diplomatic missions to get stamping. It would also impact a large number of Indian IT professionals who are seeking renewal of their H-1B visas.

“In the administration of our Nation's immigration system, we must remain mindful of the impact of foreign workers on the United States labour market, particularly in the current extraordinary environment of high domestic unemployment and depressed demand for labour,” said the proclamation issued by Trump.

In his proclamation, Trump said that the overall unemployment rate in the United States nearly quadrupled between February and May of 2020 -- producing some of the most extreme unemployment rates ever recorded by the Bureau of Labor Statistics.

While the May rate of 13.3 percent reflects a marked decline from April, millions of Americans remain out of work.

The proclamation also extends till the end of the year his previous executive order that had banned issuing of new green cards of lawful permanent residency.

Green card holders, once admitted pursuant to immigrant visas, are granted "open-market" employment authorisation documents, allowing them immediate eligibility to compete for almost any job, in any sector of the economy, he said.

“American workers compete against foreign nationals for jobs in every sector of our economy, including against millions of aliens who enter the United States to perform temporary work. Temporary workers are often accompanied by their spouses and children, many of whom also compete against American workers,” Trump said.

“Under ordinary circumstances, properly administered temporary worker programmes can provide benefits to the economy. But under the extraordinary circumstances of the economic contraction resulting from the COVID-19 outbreak, certain non-immigrant visa programmes authorising such employment pose an unusual threat to the employment of American workers,” he said.

For example, Trump said, between February and April of 2020, more than 17 million United States jobs were lost in industries in which employers are seeking to fill worker positions tied to H-2B nonimmigrant visas.

“During this same period, more than 20 million United States workers lost their jobs in key industries where employers are currently requesting H-1B and L workers to fill positions,” he said.

“Also, the May unemployment rate for young Americans, who compete with certain J non-immigrant visa applicants, has been particularly high -- 29.9 percent for 16-19-year-olds, and 23.2 percent for the 20-24-year-old group,” he said.

“The entry of additional workers through the H-1B, H-2B, J, and L non-immigrant visa programmes, therefore, presents a significant threat to employment opportunities for Americans affected by the extraordinary economic disruptions caused by the COVID-19 outbreak,” Trump said.

Trump observed that excess labour supply is particularly harmful to workers at the margin between employment and unemployment -- those who are typically "last in" during an economic expansion and "first out" during an economic contraction.

In recent years, these workers have been disproportionately represented by historically disadvantaged groups, including African Americans and other minorities, those without a college degree, and Americans with disabilities, he said.

The proclamation suspends and limits entry into the US of H-1B, H-2B and L visas and their dependents till December 31, 2020. It also includes certain categories of J visas like an intern, trainee, teacher, camp counselor, or summer work travel programme.

The new rule would apply only to those who are outside the US, do not have a valid non-immigrant visa and an official travel document other than a visa to enter the country.

According to the proclamation, it does not have an impact on lawful permanent residents of the United States and foreign nationals who are spouses or child of an American citizen.

Foreign nationals seeking to enter the US to provide temporary labour or services essential to the food supply chain are also exempted from the latest proclamation.

Washington, Jun 13: America's first-ever Hindu lawmaker Tulsi Gabbard has said that in this chaotic time, one can find certainty, strength, and peace in Bhagavad Gita.

In her message during a virtual commencement address, the 39-year-old Congresswoman from Hawaii said that it is a chaotic time and no one can say with certainty what tomorrow looks like.

"... but we find certainty, strength, and peace in the practice of Bhakti Yoga and Karma Yoga taught to us by Krishna in the Bhagavad Gita," Tulsi Gabbard told the 'Class of 2020 for Hindu students''.

Her address came amidst protests in the US against the killing of African-American George Floyd by a white police officer in Minneapolis.

The country has been swept by protests since George Floyd's custodial death on May 25 with thousands of people mounting pressure for changes to the law enforcement practices.

The first-ever virtual Hindu commencement was organised by the Hindu Students Council on June 7, which drew thousands of viewers on Facebook and YouTube Live, all coming together in solidarity during the ongoing COVID-19 crisis.

According to Johns Hopkins Coronavirus Resource Center, the contagion has infected over 76,00,000 people and killed more than 4,25,000 across the world. The US is the worst affected country with over 2.04 million cases and more than 1,14,000 deaths.

The COVID-19, which originated in China''s Wuhan city in December last year, has also battered the world economy with the International Monetary Fund saying that the global economy is bound to suffer a "severe recession".

Scientists are racing against time to find a vaccine or medicine for its treatment.

Hundreds of graduates from the US, Canada, the UK, India and Australia attended to commemorate their graduation in a unique way - by celebrating their shared Hindu values.

Professor Subhash Kak served as the ceremony's Grand Marshall.

"As you think about this new chapter in your lives, ask yourself what is my purpose in life? It is a deep question that if you can recognise now that your purpose is to serve God and God''s children, practicing Karma Yoga, then you can lead a truly successful life," Tulsi Gabbard said.

"Success is not defined by temporary material things, trinkets, glittery objects or accomplishments - but a deeply successful and happy life centered around service," she added.

The Iraq war veteran ended her presidential campaign in March and offered her full support to former vice president Joe Biden, 77, who is all set to challenge Republican incumbent Donald Trump, 73, in November elections.

The commencement address focused heavily on themes from the Bhagavad Gita, a timeless historical text that many Hindus consider their moral framework.

Professor Kak, Regent Professor at Oklahoma State University and 2019 Padma Shri recipient, read out the names of the graduating students.

"I exhort you - the graduating students - to be the leaders of the new world where education is less of the mind of a vessel to be filled with information (usually forgotten after the semester is over), and more of a flame that is lit as envisioned by our Vedic sages," he said.

The student speakers were from many university campuses, including the Massachusetts Institute of Technology, Princeton, and Stanford.
