Modi govt slams UN for opposing its decision to deport helpless Rohingyas

New Delhi, Jun 10: India on Wednesday reported a spike of 9,985 more COVID-19 cases in the last 24 hours, taking the country's COVID-19 count to 2,76,583, according to the Union Ministry of Health and Family Welfare.

279 deaths were reported in the last 24 hours taking the total death toll to 7,745.

The total number of active cases has reached 1,33,632 while 1,35,205 patients have recovered. While one person has migrated.

With 90,787 cases, Maharashtra reported the highest number of coronavirus cases in the country followed by Tamil Nadu with 34,914 cases.

According to the Indian Council of Medical Research (ICMR), 1,45,216 samples were tested in the last 24 hours while overall 50,61,332 samples have been tested so far.

New Delhi, Feb 26: Calling the recent violence in Delhi as 'planned conspiracy', Sonia Gandhi on Wednesday demanded Union Home Minister Amit Shah's resignation over the clashes that left 20 people dead in two days.

"CWC (Congress Working Committee) believes Home Minister and Centre is responsible. The Home Minister should tender his resignation with immediate effect," the Congress party's interim chief told reporters here.

Violent clashes erupted between pro and anti-CAA groups in parts of northeast Delhi on Monday, leading to widespread vandalism and arson for over two days.

While many blamed police for inaction to control the mobs, Union Home Minister Amit Shah met the top brass of Delhi Police, Chief Minister Arvind Kejriwal, LG Anil Baijal and directed the officials to control the situation.

Gandhi blamed both the Central and the Delhi governments, saying the administration did not take adequate steps on time to curb violence in the national capital.

"Chief Minister Arvind Kejriwal and Center is equally responsible for not activating the administration to reach out to the people to maintain peace and harmony," Sonia added.

The death toll in the violence rose to 20 on Wednesday, according to GTB hospital authorities.

Government sources told ANI that the National Security Advisor (NSA) Ajit Doval has been given the charge of bringing normalcy in the capital.

Sources also said that Doval will brief Prime Minister Narendra Modi and the Cabinet about the prevailing situation.

The NSA last night visited Jaffrabad, Seelampur and other parts of northeast Delhi where he held talks with leaders of different communities.

Without naming any leader, the Congress interim president also targeted the leaders of the Bharatiya Janata Party for making inflammatory statements saying that "there is a conspiracy behind the violence, country also saw this during Delhi elections. Many BJP leaders made inciting comments creating an atmosphere of fear and hatred."

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.
