No probe against Amit Shah’s son: Rajnath Singh

New Delhi, Jun 3: Seasoned diplomat and former spokesperson of the External Affairs Ministry Raveesh Kumar has been appointed as India's next Ambassador to Finland, the government announced on Wednesday.

Raveesh Kumar, a 1995-batch Indian Foreign Service officer, served as the spokesperson of the MEA from July 2017 to April 2020 during which he deftly articulated India's position on a number of sensitive issues including last year's Balakot strike, reorganisation of Jammu and Kashmir and the controversy surrounding the National Register of Citizens.

"He is expected to take up the assignment shortly," the MEA said.

Before becoming the MEA spokesperson, Kumar was serving as Consul General of India in Frankfurt.

Kumar started his career at the Indian Mission in Jakarta and it was followed by his postings in Thimpu and London.

In his nearly 25-year career, Kumar also looked after the East Asia desk in the headquarters of the MEA in Delhi and served as Deputy Chief of Mission in Jakarta followed by his posting as Consul General in Frankfurt from August 2013 to July 2017.

In Finland, he succeeds Vani Rao.

Finland is an important country for India in Europe, and bilateral trade has been on an upswing in the last few years.

Around 35 Indian companies have invested in Finland in IT, healthcare, hospitality and automotive sectors while over 100 Finnish companies have operations in India in energy, textiles, power plants and electronics sectors.

Tirupur, Feb 20: Nineteen people died in a collision between a Kerala State Road Transport Corporation bus and a truck near Avinashi town of Tirupur district on Thursday morning here.

The bus was on its way to Ernakulam in Kerala from Bengaluru in Karnataka when the mishap occurred.

Deputy Tehsildar of Avinashi Town informed, "19 people that include 14 men and 5 women, died in the collision between the bus and the truck near Avinashi town."

The bodies have been taken to Tirupur government hospital.
Further details are awaited.

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.
