Life sentence to ‘most wanted’ host Suhaib Ilyasi for murdering wife

Jun 5: Underworld don Dawood Ibrahim and his wife Mahzabeen have tested positive for COVID-19, a top government source told CNN News 18. They were admitted to the Army Hospital in Karachi.

Some of Dawood's personal staff and guards have also been quarantined, the report said on Friday.

Dawood was the mastermind of the 1993 Mumbai blasts and is one of the most-wanted gangsters by India. He has allegedly been living in Pakistan but the neighbouring country has always refusing to accept it.

Earlier in the day, a senior diplomat of the American embassy in Pakistan has tested positive for the novel coronavirus, a media report said.

In a statement, the embassy's spokesman said that while maintaining the privacy, the name of the citizen would not be disclosed.

The US State Department is responsible to protect its citizens, wherever they are, the spokesman added. In coordination with the Pakistani authorities, the consulate is working to enforce the coronavirus protocol in order to stem its spread. The spokesman added that isolation wards, contact tracing and quarantine facility are part of such protocols.

Meanwhile, Pakistan has 89,249 COVID-19 cases and the death toll is 1,838.

Motera, Feb 23: A day before US President Donald Trump's visit to Ahmedabad, a makeshift VVIP entry gate erected outside the newly-built cricket stadium in Motera area here collapsed due to gusty winds on Sunday morning, an official said.

The entire incident was recorded by a bystander and aired on local television channels.

The makeshift entry gate was made of welded steel rods and covered in flex banners.

After some time, a portion of another makeshift gate structure at the stadium's main entrance also collapsed due to the windy weather, another official said.

No one was injured in both the incidents and work was underway to put the structures back in place, he said.

"The (VVIP) entry gate collapsed when fabrication work was going on. It was not a major incident. No one was injured in the incident," said Special Commissioner of Police, Crime Branch, Ajay Tomar said.

President Trump and Prime Minister Narendra Modi will participate in a roadshow here on Monday and later address the 'Namaste Trump' event at the Sardar Patel Stadium in Motera area where over one lakh people are expected to be present.

The stadium has already received 'Building Use' permission from the Ahmedabad Municipal Corporation, an official earlier said.

It is the world's largest stadium with a capacity to accommodate 1.10 lakh spectators.

The stadium has been rebuilt after demolishing the old one which had a seating capacity of 49,000 spectators.

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.
