Hindustan a country of Hindus but it doesn't exclude others: RSS chief

Bengaluru, May 29: Karnataka reported 248 new cases of coronavirus on Friday, and with that, the state tally surged to 2,781. 

A 50-year-old woman, resident of Chikkaballapura district, succumbed to the infection on Friday. She was admitted to a private hospital on May 24 following acute kidney injury and pneumonia. As her condition deterorted, she was shifted to a designated hospital in Bengaluru Urban on May 28, where she tested COVID-19 positive.

Out of the 248 cases, only 16 persons have contracted the virus inside the state. The remaining are the people who have returned from Maharashtra, Delhi, Andhra Pradesh, Tamil Nadu and Ireland.

The maximum number of people, who tested positive for COVID-19, have returned from Maharashtra. Most of these people are residents of Udupi, Kalaburagi, Yadagiri and Raichuru.

Besides, five people have a travel history to Delhi, while one person each has tested positive on returning from Andhra Pradesh, Tamil Nadu, Rajasthan and Ireland.

Fifteen people have tested positive within the state and have been infected by persons who had previously tested positive or have a history of Influenza-like Illness and Severe Acute Respiratory Illness.

Out of all the cases, 10 have been reported in Bengaluru Urban while one has come up in Bengaluru Rural.

Meanwhile, on Thursday, the Karnataka government asked the Civil Aviation Ministry to reduce the number of flights coming in the state from the five worst-hit states -- Maharashtra, Tamil Nadu, Gujarat, Madhya Pradesh and Rajasthan.

"Karnataka has appealed to the Civil Aviation Ministry to take steps to lessen the air traffic to the state, with the sacred intention that there may not be adequate quarantine facilities if there is a huge turnout in a short span of time," state Law and Parliamentary Affairs Minister J.C. Madhuswamy explained.

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.

Bengaluru, May 2: Karnataka Pradesh Congress Committee (KPCC) president DK Shivakumar has urged Chief Minister BS Yediyurappa to help the farmers in sending their produce to a market here amid the coronavirus lockdown.

The Congress leader made the appeal to the Chief Minister after listening to the farmers' issues while visiting KR Puram market on Friday.

Farmers told Shivakumar that the police are stopping their vehicles going towards the market despite the order passed by the Centre permitting the movement of vehicles carrying essential commodities during the lockdown.

"I have received calls from more than 100 farmers in the past few days. Every day, farmers from Kolar, Chikballapur, Malur and many other places come to KR Puram market to sell their agricultural goods, but their vehicles are stopped by the police. The cops do not allow them to sell fruits and vegetables. I request the Chief Minister to look into the matter and help the farmers," Shivakumar told reporters.

"I got to know that more than 50 vehicles were sent back. This government is of no use if they cannot secure the interests of the farmers. This government is not providing required support to the farmers," he added.

The Congress leader was accompanied by MLC Narayana Swamy and former president of Hoskote Authority Narayana Gowda during the visit to KR Puram market.
