Washington, Jun 3: US President Donald Trump's administration on Tuesday announced investigations into foreign digital services taxes it says are aimed squarely at American tech firms.

Following a similar trade investigation against France last year, the US Trade Representative office now is looking into taxes in Britain and the European Union, as well as Indonesia, Turkey and India.

"President Trump is concerned that many of our trading partners are adopting tax schemes designed to unfairly target our companies," USTR Robert Lighthizer said in a statement.

"We are prepared to take all appropriate action to defend our businesses and workers against any such discrimination."

Washington opposes the efforts to tax revenues from online sales and advertising, saying they single out US tech giants like Google, Apple, Facebook, Amazon and Netflix.

The US and France have agreed to negotiate till the end of the year over a digital services tax Paris approved in 2019, after USTR found them to be discriminating and threatened retaliatory duties of up to 100 percent on French imports such as champagne and camembert cheese.

Trump has embroiled the US in numerous trade disputes since taking office in 2017, including a months-long trade war with China that cooled with the signing of a partial deal in January.

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.

Amsterdam, Jun 18: A statue of Mahatma Gandhi has been vandalised here in the capital of Netherlands by unknown miscreants with graffiti and spray painting, amid a wave of attacks on controversial figures following the protests around the world after the custodial killing of African-American George Floyd, according to media reports.

The statue of Gandhi on the Churchilllaan in Amsterdam was covered with red paint and the pedestal has 'racist' and an abbreviation for an expletive against the police chalked on it, Metro, the Dutch newspaper, reported.

According to alderman Rutger Groot Wassink, the municipality will file a declaration for daubing.

"Obviously, we are opposed to any form of vandalism and daubing of these things is completely unacceptable," the city official was quoted as saying by the AD.nl.

"It is logical that we will file a declaration, the image will be cleaned," Wassink said.

It is not yet known who is behind the daubing. An employee of the Kunstwacht, who provides maintenance and repairs, says that the cleaning work can take hours.

A 75-year-old man saw the daubs on Wednesday and called the municipality. “I have lived here for forty years and I have never experienced this. I have been watching the statue for years," the man said.

Since the death of 46-year-old Floyd on May 25 in Minneapolis, US, and subsequent worldwide Black Lives Matter protests, there has been much debate about street names and statues of people with a colonial past. All over the world, statues of controversial historical figures are brought down or defaced.

Recently, images and buildings have been defaced in various places that refer to the colonial past of the Netherlands, including the Tropenmuseum in Amsterdam and the statue of Piet Hein in Rotterdam. These are anti-racist expressions that follow the death of Floyd through a white police officer, Metro reported.

Gandhi was known as a champion of human rights and non-violence. But in his twenties, which he spent in South Africa, he still called black people “troublesome, very dirty and they live like beasts” and found that the white people were the “dominant race”. Later he renounced those ideas, the report added.

The statue was unveiled on the Churchillaan on October 2, 1990 in honour of Gandhi's 121st birthday.

The design was made by the sculptor Karel Gomes, who died in 2016. At the time, the plan for the statue came from the Hindu organisation Triveda.

Gandhi is depicted walking, featuring robes around the body, slippers on the feet, a book in one hand and a stick in the other.
