MH370 co-pilot made mid-flight phone call: Report

The Japan government on Monday decided to lift the state of emergency for COVID-19 in Tokyo and four other prefectures of the country, the only places where the measure implemented to curb the pandemic had remained in force.

The lifting of the alert was backed by the coronavirus advisory panel and will be formally approved by the government later day, the economic revitalization minister and head of the working group to coordinate Japan's fight against COVID-19, Yasutoshi Nishimura, said.

The Japanese authorities made the decision after taking into account the number of infections and the situation of the health system in Tokyo, the three neighbouring prefectures of Chiba, Kanagawa and Saitama and the northern Hokkaido, the only ones where the state of emergency declared more than a month ago to control the pandemic remained in effect, reports Efe news.

The health alert was initially declared in Tokyo and six other prefectures on April 17 and subsequently extended across the country.

It allowed local authorities to ban large-scale public events and close bars and restaurants at night, among other measures, while the government has launched a campaign to encourage teleworking and staying at home.

The government resorted to this measure for the first time in the country's recent history to contain the spread of the virus and is now withdrawing it after a sustained slowdown in infections throughout the archipelago, where around 16,600 confirmed COVID-19 cases and 839 deaths have been recorded, according to the latest data.

The group of experts advising the government appreciated the efforts made by citizens to comply with the recommendations to achieve the target of reducing interpersonal contact by 80 percent, top government spokesperson Yoshihide Suga said at a press conference on Monday.

The recommendation for citizens to avoid unnecessary trips outside and the request for non-essential businesses to close were not mandatory nor accompanied by fines or other penalties for non-compliance, unlike the stricter containment measures implemented in other countries.

The government plans to formally approve the lifting of the state of emergency on Monday after consulting with other political parties in parliament and another meeting with the advisory panel, following which Japanese Prime Minister Shinzo Abe will hold a press conference.

The government had already decided to lift the emergency in 39 prefectures on May 14 after they reported a marked decrease in the number of infections, leaving out the more populated regions such as Tokyo and Osaka.

To avoid new outbreaks of the virus, Abe has urged people to become accustomed to a "new lifestyle" that includes maintaining social distancing, the use of masks outside as well as a series of guidelines for the reopening of shops, restaurants and public facilities.

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.

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.
