Indian peacekeepers prevented more casualties in S Sudan: UN official

The Seattle City Council, one of the most powerful city councils in the U.S., on Monday unanimously passed a resolution condemning India’s recently-enacted Citizenship Amendment Act (CAA) and the National Register of Citizens (NRC).

Reaffirming Seattle as a welcoming city and expressing solidarity with the city’s South Asian community regardless of religion and caste, the resolution “resolves that the Seattle City Council opposes the National Register of Citizens and the Citizenship Amendment Act in India, and finds these policies to be discriminatory to Muslims, oppressed castes, women, indigenous, and LGBT people“.

Introduced by Indian American City Council member Kshama Sawant, the resolution urges the Parliament of India to uphold the Indian Constitution by repealing the CAA, and to stop the National Register of Citizens, and take steps towards helping refugees by ratifying various UN treaties on refugees.

“Seattle City’s decision to condemn CAA should be a message to all who wish to undermine pluralism and religious freedom. They cannot peddle in hate and bigotry, and expect to have international acceptability at the same time,” said Ahsan Khan, president of Indian American Muslim Council.

Thenmozhi Soundararajan of Equality Labs, which organised the community in support of the resolution, welcomed its passage. “We are proud of the Seattle City Council for standing on the right side of history today. Seattle is leading the moral consensus in the global outcry against the CAA, she said.

Soundararajan said that thousands of organizers across the country have called, e-mailed, and visited Seattle City Council members to amplify this resolution, and it sets an example to cities across the United States.

“At a time when members of the Indian ruling party sided Trump, the Muslim ban, and his war on immigrants as justification for targeting hundreds of millions of Indian minorities, Americans have a unique responsibility to stand up and speak about this human rights crisis. We are glad that Seattle is leading the way on this,” she said.

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.

Washington, Apr 17: The confirmed coronavirus death toll in the United States reached 32,917 on Thursday, according to a tally by Johns Hopkins University.

The toll as of 8:30 pm (0030 GMT Friday) marked an increase of 4,491 deaths in the past 24 hours, by far the highest daily toll in the pandemic so far.

But the figure likely includes "probable" deaths related to COVID-19, which were not previously included. This week, New York City announced it would add 3,778 "probable" coronavirus deaths to its toll.

As of Thursday night, the US Centers for Disease Control and Prevention had recorded 31,071 coronavirus deaths, including 4,141 "probable" virus deaths.

The US has the highest death toll in the world, followed by Italy with 22,170 dead although its population is just a fifth of that of the US.

Spain has recorded 19,130 deaths, followed by France with 17,920.

More than 667,800 coronavirus cases have been recorded in the United States, which has seen a record number of deaths over the past two days.

Meanwhile, President Donald Trump unveiled plans Thursday evening to reopen the US economy, allowing each state's governor "to take a phased deliberate approach to reopening their individual states".
