Will ensure that BJP wins all 28 seats of Karnataka in 2019 Lok Sabha polls: BSY

Bengaluru, Jan 16: Former chief minister Siddaramaiah and other leaders are likely to make the final decision on the name of the next Congress president of Karnataka soon, said party leader Dinesh Gundu Rao on Thursday.

"He (Siddaramaiah) has met all the leaders and I think soon they will make a decision. It has already been delayed, it should not have been delayed so much. I am sure high command will take a decision on this," Rao told reporters here.

Both Siddaramaiah and Gundu Rao had resigned from their posts, Leader of Congress Legislature Party and KPCC president, after the party's drubbing in the bye-elections held for 15 Assembly seats last year.

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.

Mangaluru, Jun 26: In a gut-wrenching incident, a pack of stray dogs attacked a herd of barking deer, also known as Indian muntjac at Dr Shivaram Karanth Biological Park at Pilikula on the outskirts of the city last night.

Dhama H Jayaprakash Bhandary, director of the biological park said: “Due to heavy rains a tree was uprooted damaging the compound wall of the park one day ago. Last night pack of stray dogs entered the park and attacked the barking deer. When the incident came to light, 10 barking deer had lost their lives and many others were injured.”

He said that five years ago they had rescued four barking deer that bred and multiplied to 40. “We had planned to release some of the barking deer to jungle and retain around a dozen in the park. Last night’s incident has shocked us,” he said, adding that the injured barking deer are being treated.
