Will work with like-minded parties to defeat communal forces: Sonia

New Delhi, Jan 15: A Delhi court on Wednesday granted bail to Bhim Army chief Chandrashekhar Azad in connection with the Daryaganj violence case.

The court has ordered him not to hold any protest in Delhi till February 16th.

While hearing the case, the Judge had asked Azad's counsel to read out some of his social media posts.

Advocate Mehmood Pracha, representing Azad, had on Tuesday said that the petitioner was sent to jail without any evidence in connection with anti-CAA protests in Delhi's Darya Ganj area last year.

"I think the court's comments should become a precedent for the country. The Public Prosecutor at the behest of police tried to make this a communal issue. We told the court that the government has a problem with Azad because he made the CAA-NPR-NRC an issue for everyone. 
The Court also sought evidence," Pracha told ANI after Delhi's Tis Hazari court deferred the bail plea of Azad till today.

On Wednesday, the court pulled up the Delhi Police for failing to show any evidence against Azad.

Azad was arrested on December 21 last year after he led a march from Jama Masjid against the Citizenship (Amendment) Act. He was sent to judicial custody till January 18 at Tihar jail.

The Bhim Army chief was charged with rioting, unlawful assembly and inciting the mob to indulge in violence after vandalism in Delhi's Daryaganj area.

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.

Riyadh, Apr 27: The government of Saudi Arabia has signed a SR995 million (approx. Dh972m) contract with China to provide Covid-19 tests for nine million people in the Kingdom.

The Saudi Press Agency, SPA, reported that the decision came "as a result of a phone call made today (Sunday) between the Custodian of the Two Holy Mosques King Salman bin Abdulaziz Al Saud and Chinese President Xi Jinping."

The contract includes providing necessary equipment and supplies, making available of 500 Chinese specialists and technicians who are specialised in performing tests, establishing six large regional laboratories throughout the Kingdom; including a mobile laboratory with a capacity of performing 10,000 tests per day. Saudi cadres will also be trained to conduct daily tests and comprehensive field tests, under the new agreement

The contract was co-signed by the National Unified Procurement Company and Chinese company Huo-yan Laboratories by Dr. Abdullah Al Rabeeah, Advisor at the Royal Court, on behalf of the Government of Saudi Arabia, and Chinese Ambassador to the Kingdom Chen Weiqing, as a representative of the Chinese Government.

The contract is one of the largest contracts that will provide diagnostic tests for the novel Coronavirus.

Tests were also purchased from several other companies from the United States, Switzerland and South Korea, bringing the number of available tests to 14.5 million, covering around 40 percent of Saudi Arabia's population, SPA added.
