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, Jan 3: US President Donald Trump ordered the killing of Iran Revolutionary Guards commander Qasem Soleimani, who died in Baghdad "in a decisive defensive action to protect US personnel abroad," the Pentagon said Thursday.

"General Soleimani was actively developing plans to attack American diplomats and service members in Iraq and throughout the region. General Soleimani and his Quds Force were responsible for the deaths of hundreds of American and coalition service members and the wounding of thousands more," the Department of Defense said.

Following Soleimani's death, Trump tweeted an image of the US flag without any further explanation.

"US' act of international terrorism, assassinating General Soleimani—the most effective force fighting Daesh (ISIS), Al Nusrah,Al Qaeda, is extremely dangerous & foolish escalation. US bears responsibility for all consequences of rogue adventurism." said Iran Foreign Minister Javad Zarif.

Srinagar, Jun 30: On the deadly attack at Karachi Stock Exchange on Monday morning, a Kashmiri social activist and journalist warned that the incident is a stark reminder to all those in Pakistan supporting Jihad and attacked Pakistan prime minister Imran Khan for ignoring development agenda in Balochistan.

Yana Mir, the editor-in-chief of The Real Kashmir News, said, "Karachi Stock Exchange attack is a reminder to all those in Pakistan supporting Jihad. Remember @imrankhan that Youth is restless and they want development agenda. These young boys of BLA are also looking for a life which is settled and peaceful. Wake up Imran Khan and you Kashmiris also. Pakistan is going to finish you. Open your eyes."
Four heavily armed terrorists attacked the busy Pakistan Stock Exchange building in Karachi with grenades today, killing four security guards and a police officer before being shot dead in an exchange of fire, authorities said.

The terrorists, who arrived in a car, stormed the Karachi Stock Exchange building by firing indiscriminately and lobbed grenades at the main gate of the multi-storey building situated in the city's high-security commercial hub.

Balochistan is a well-known region rich in natural resources but the Balochis have always been deprived of basic facilities. No hospitals are available in Balochistan. If there are some then medical facilities and equipment are not available in hospitals. The education system is pathetic and similar is the case with the infrastructure: the roads, water system, agriculture and almost all fields of life.

It is pertinent to mention that enforced disappearances and abductions by the Pakistani military establishment have also been carried out regularly and for innumerable times in Balochistan. Leaders, activists, and vocal members of various student organizations have been detained by the security forces and kept in confinement. While others have been shot dead.

This crime against humanity has been going on for so long and so systematically in Balochistan that it has come to be considered as a normal state of affairs in the province. Many social and human rights activists have flagged the issue of oppression by the Pakistani establishment before the United Nations and other international agencies.

According to the Commission of Inquiry on Enforced Disappearances, an entity established by the Pakistani government, about 5,000 cases of enforced disappearances have been registered since 2014. Most of them are still unresolved.

Independent local and international human rights organisations put the numbers much higher. Around 20,000 have reportedly been abducted only from Balochistan, out of which more than 2,500 have turned up dead as bullet-riddled dead bodies, bearing signs of extreme torture.

Before being elected as Prime Minister, Imran Khan had admitted in multiple interviews about the involvement of Pakistan's intelligence agencies in enforced disappearances as well as extrajudicial killings and vowed to resign if he was unable to put an end to the practice, holding those involved responsible. But times have passed and only reports are available to narrate the true story.
