China locks down ten more Beijing neighbourhoods over COVID-19 cluster

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.

Ramallah, Jul 2: Several world countries renew a call for Israel to halt contentious plans to annex parts of the occupied Palestinian territory after the regime delayed the implementation of the land garb bid in the face of a series of stumbling blocks, including internal rifts, global criticisms and the US’s failure to give Tel Aviv the go-ahead for the move.

Israel's ruling coalition, led by Prime Minister Benjamin Netanyahu, had announced July 1 as the date to begin moving forward with the plan to impose Tel Aviv’s “sovereignty” over about a third of the West Bank, including settlements and the fertile Jordan Valley.

Without clarifications, the regime, however, failed to launch the scheme on the set date amid widening differences between Netanyahu and his coalition partner, minister of military affairs Benny Gantz.

Meanwhile, there are signs that the administration of US President Donald Trump, a staunch Israel supporter, has cooled its backing for the Israeli move amid what is believed to be troubles at home and fears that it might hurt the president’s chances of re-election besides international pressure.

On Wednesday, Netanyahu's office said in a statement that he would continue to discuss a possible West bank annexation with the US administration.

“In the coming days there will be additional discussions,” the statement said.

Labor, Social Affairs and Social Services Minister Ofir Akunis said the Israel would annex portions of the West Bank in July but only after the US president issued a declaration on the matter.

The annexation “will only happen after a declaration by Trump,” he told Israeli Army Radio.

Trump had already given Tel Aviv the green light for the land grab in his self-proclaimed “deal of the century,” which was unveiled in January with the aim of re-drawing the Middle East map.

However, the Trump administration has so far refrained from offering official support for the annexation sought by Netanyahu and his right-wing allies.

Unlike the US, several countries, including some of Israel’s allies, have expressed their opposition to Israel’s planned push to consolidate its occupation of Palestine.

Germany passes anti-annexation resolution

On Wednesday, the German parliament approved a resolution calling on the government to dissuade Israel from annexing the West Bank.

The motion, which was brought in the German legislature by the three parties in Chancellor Angela Merkel's coalition, was approved without opposing votes. 

Berlin should use its “special relations and contacts [with Tel Aviv] to express to the Israeli government our concerns and our urgent demand to refrain from an annexation of parts of the West Bank and from the continued expansion of settlements, both of which contradict international law,” read the resolution.

Speaking at the parliamentary debate before the vote, German Foreign Minister Heiko Maas said, “We reject unilateral changes of borders, and we won’t recognize them.”

He also stressed that peace “cannot be achieved through unilateral steps but only through serious negotiations.”

France warns of consequences

Similarly, French Foreign Minister, Jean-Yves Le Drian warned that any Israeli annexation would be a violation of international law and would bring about consequences.

“Annexation of Palestinian territories, whatever the perimeters, would seriously throw into question the parameters to resolve the conflict,” he told a parliamentary hearing. 

The top diplomat added, “An annexation decision could not be left without consequences and we are examining different options at a national level and also in coordination with our main European partners.”

Australia raises concerns

Additionally, Australian Foreign Minister Marise Payne voiced worries about the Israeli scheme, saying she had directly expressed this view to Israeli Foreign Minister Gabi Ashkenazi.

“We are following with concern possible moves towards the unilateral annexation or change in status of territory on the West Bank,” she said in a statement.

“The focus needs to be on a return to direct and genuine negotiations between Israel and the Palestinians for a durable and resilient peace arrangement, as soon as possible,” Payne added.

Vatican summons US, Israeli envoys

Meanwhile, the Vatican announced on Wednesday that it had summoned the American and Israeli ambassadors to protest Israel’s annexation bid.

In separate meetings, Vatican Secretary of State Cardinal Pietro Parolin told Israeli Ambassador Oren David and US Ambassador Callista Gingrich of concerns “regarding possible unilateral actions that may further jeopardize the search for peace between Israelis and Palestinians, as well as the delicate situation in the Middle East,”

“As already declared … the Holy See reiterates that ... Israel and the State of Palestine have the right to exist and to live in peace and security, within internationally recognized borders,” the Vatican said in a statement.

“It thus appeals to the parties to do everything possible to reopen the process of direct negotiation, on the basis of the relevant Resolutions of the United Nations,” it added.

Amnesty urges firm action

Amnesty International called on the international community to take firm action against Israel’s annexation plan and its “law of the jungle” mentality.

“Members of the international community must enforce international law and restate that annexation of any part of the occupied West Bank is null and void,” said Saleh Higazi, deputy regional director for Amnesty Middle East and North Africa.

“They must also work to immediately stop the construction or expansion of illegal Israeli settlements and related infrastructure in the Occupied Palestinian Territories as a first step towards removing Israeli civilians living in such settlements,” he added.

Palestinians mark ‘Day of Rage'

Also on Wednesday, Palestinians held “Day of Rage” rallies both in the West Bank and the Gaza Strip against the Israeli expansionism.

In Gaza city, several thousand protesters gathered, some brandishing Palestinian national flags and placards condemning Trump.

Some demonstrators carried signs in English reading, “We Can’t Breathe Since 1948” and “Palestinian Lives Matter,” in reference to the American Black Lives Matter movement.

“The occupation has killed us and killed our children and deprived us of a good life. May God grant the Resistance victory,” a protester told the al-Aqsa TV.

“The resistance must be revived,” Gaza protester Rafeeq Inaiah told media persons. “Israel is afraid of force.”

Similar demonstrations also took place in the West Bank cities of Ramallah and Jericho.

Washington D.C, Jun 4: A lawsuit has been filed against US President Donald Trump for signing an executive order on preventing online censorship that seems to violate the freedom of speech of individuals on social media platforms.

On Tuesday, the Center for Democracy and Technology filed the lawsuit against Trump's "Executive Order on Preventing Online Censorship," which was signed May 28, 2020. The suit argues that the Executive Order violates the First Amendment by curtailing and chilling the constitutionally protected speech of online platforms and individuals.

"CDT filed suit today because the President's actions are a direct attack on the freedom of speech protected by the First Amendment. The government cannot and should not force online intermediaries into moderating speech according to the President's whims. Blocking this order is crucial for protecting freedom of speech and continuing important work to ensure the integrity of the 2020 election," said CDT President and CEO Alexandra Givens.

The executive order is designed to deter social media services from fighting misinformation, voter suppression, and the stoking of violence on their platforms, the digital rights group said.

"Access to accurate information about the voting process and the security of our elections infrastructure is the lifeblood of our democracy. The President has made clear that his goal is to use threats of retaliation and future regulation to intimidate intermediaries into changing how they moderate content, essentially ensuring that the dangers of voter suppression and disinformation will grow unchecked in an election year," Givens said.

The law firm of Mayer Brown is representing CDT in this action.
