Horrified at violence against women in India, says US

Sydney, Jan 8:  Authorities in Australia will begin five-day campaign to kill thousands of camels in the country as they drink too much water amid the wildfires.  The government will send helicopters to kill up to 10,000 camels in a five-day campaign starting Wednesday, The Hill reported citing The Australian.

Marita Baker, an Anangu Pitjantjatjara Yankunytjatjara (APY) (large, sparsely-populated local government area for Aboriginal Australians) executive board member, said that the camels were causing problems in her community of Kanypi.

"We have been stuck in stinking hot and uncomfortable conditions, feeling unwell, because the camels are coming in and knocking down fences, getting in around the houses and trying to get to water through air conditioners,'' she said.

The planned killing of the camels comes at a time the country is ravaged by wildfires since November. The disaster has killed more than a dozen people and caused the displacement or deaths of 480 million animals, according to University of Sydney researchers.

Karachi, Jun 22: India-born renowned Pakistani Shia scholar and author Talib Jauhari passed away here after a prolonged illness. He was 80.

Jauhari, who was born on August 27, 1939 in Patna, is survived by his three sons, Dawn News reported on Monday.

He migrated to Pakistan along with his father in 1949, two years after the Partition.

After obtaining early education from his father, he went to Iraq where he studied religion for 10 years under the renowned Shia scholars of that time.

Jauhari, who was on a ventilator in the intensive care unit of a private hospital for the past 15 days, breathed his last on Sunday night.

His son Riaz Jauhari confirmed his death and said that the body has been shifted to Ancholi Imambargah for the funeral prayers, The Express Tribune newspaper quoted his son as saying.

Jauhari was respected among his sect as he was a class fellow of the widely revered scholar Ayatollah Sayyid Ali al-Husayni al-Sistani.

He was also a poet, historian and philosopher and authored many books.

Pakistan Prime Minister Imran Khan has condoled Jauhari's death.

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.
