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.

United Nations, Jan 2: Nearly 400,000 babies were born around the world on New Year's Day with India recording the highest number of these births worldwide at 67,385, the UN children's agency said.

An estimated 392,078 babies were born around the world on New Year's Day, according to UNICEF. Of this, an estimated 67,385 babies were born in India, the most globally. China comes in second with 46,299 births.

The beginning of a new year and a new decade is an opportunity to reflect on our hopes and aspirations not only for our future, but the future of those who will come after us,” UNICEF Executive Director Henrietta Fore said.

As the calendar flips each January, we are reminded of all the possibility and potential of each child embarking on her or his life's journey—if they are just given that chance.”

Fiji in the Pacific most likely delivered 2020's first baby, while the US, the last of the New Year's Day. Globally, over half of these births were estimated to have taken place in eight countries - India (67,385), China (46,299), Nigeria (26,039), Pakistan (16,787), Indonesia (13,020), United States of America (10,452), Democratic Republic of Congo (10,247) and Ethiopia (8,493).

Each January, UNICEF celebrates babies born on New Year's Day, an auspicious day for child birth around the world, it said. However, for millions of newborns around the world, the day of their birth is far less auspicious.

In 2018, 2.5 million newborns died in just their first month of life; about a third of them on the first day of life. Among those children, most died from preventable causes such as premature birth, complications during delivery, and infections like sepsis. In addition, more than 2.5 million babies are born dead each year.

UNICEF said over the past three decades, the world has seen remarkable progress in child survival, cutting the number of children worldwide who die before their fifth birthday by more than half. But there has been slower progress for newborns. Babies dying in the first month accounted for 47 per cent of all deaths among children under five in 2018, up from 40 per cent in 1990.

UNICEF's Every Child Alive campaign calls for immediate investment in health workers with the right training, who are equipped with the right medicines to ensure every mother and newborn is cared for by a safe pair of hands to prevent and treat complications during pregnancy, delivery and birth.

Too many mothers and newborns are not being cared for by a trained and equipped midwife or nurse, and the results are devastating,” said Fore. “We can ensure that millions of babies survive their first day and live into this decade and beyond if every one of them is born into a safe pair of hands.”

India is projected to surpass China as the world's most populous country around 2027. According to UN estimates, India is expected to add nearly 273 million people between 2019 and 2050, while the population of Nigeria is projected to grow by 200 million. Together, these two countries could account for 23 per cent of the global population increase to 2050.

China, with 1.43 billion people in 2019, and India, with 1.37 billion, have long been the two most populous countries of the world, comprising 19 and 18 per cent, respectively, of the global total in 2019. Through the end of the century, India is estimated to remain the world's most populous country with nearly 1.5 billion inhabitants, followed by China with just under 1.1 billion, Nigeria with 733 million, the US with 434 million, and Pakistan with 403 million inhabitants.

New Delhi, May 9: Three promoters of Ram Dev International, recently booked by the CBI for allegedly cheating a consortium of six banks to the tune of Rs 411 crore, have already fled the country before the State Bank of India reached the agency with the complaint, officials said on Saturday.

The CBI had recently booked the company engaged in export of Basmati rice to the West Asian and European countries and its directors Naresh Kumar, Suresh Kumar and Sangita on the basis of complaint from the State Bank of India (SBI), which suffered the loss of more than Rs 173 crore, they said.

The company had three rice milling plants, besides eight sorting and grading units in Karnal district with offices in Saudi Arabia and Dubai for trading purposes, the SBI complaint said.

Besides SBI, other members of consortium are Canara Bank, Union Bank of India, IDBI, Central Bank of India and Corporation Bank, they said.

The Central Bureau of Investigation (CBI) did not carry out any searches in the matter because of the coronavirus-induced lockdown, the officials said.

The agency will start the process of summoning the accused, incase they do not join the investigation, appropriate legal action will be initiated, they said.

According to the complaint filed by SBI, the account had become non-performing asset (NPA) on January 27, 2016.

The banks conducted a joint inspection of properties in August and October, nearly 7-9 months later only to find Haryana Police security guards deployed there, they said.

"On inquiry, it has been come to notice that borrowers are absconding and have left the country," the complaint filed on February 25, 2020, after over a year of account becoming NPA, the officials said.

The complaint alleged that borrowers had removed entire machinery from old plant and fudged the balance sheets in order to unlawfully gain at the cost of banks'' funds, it said.
