Bengaluru, Apr 15: Karnataka government will explore Ayurveda for fighting the deadly COVID-19, Ayurveda practitioner Dr Giridhar Kaje said here on Wednesday.

After meeting the Chief Minister, Dr Kaje informed media that on a trial basis, ten Coronavirus patients will be administered Ayurvedic treatment in a designated hospital.

Chief Minister B S Yediyurappa has consulted senior doctors on the issue, he said.

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, Jan 19: The Karnataka government has given its nod to teach 'Vivekadeepini' slokhas, authored by Adi Shankaracharya, in schools across the state, Chief Minister B S Yediyurappa said on Saturday.

At an event called 'Vivekadeepini Mahasamarpane,' organised by Vedanta Bharati, Yediyurappa said, "It has been noticed that Vivekadeepini, which evolves the mind and illumines a person, has a great effect on students.

Parents and teachers have found a positive change among children who were inspired by Vivekadeepini." "Hence, the government has given its nod to allow teaching Vivekadeepini in the schools in Karnataka," he added.

According to the organisers of the event, around two lakh children from 50 schools participated in the event where they were taught to chant Vivekadeepini, comprising verses for the seekers in the spiritual journey.

Yediyurappa reminded the audience that the Indian culture and civilisation is the oldest and the best, which they should feel proud of. Likening Amit Shah to the first union home minister Sardar Vallabhbhai Patel, he said, "After Sardar Vallabh Bhai Patel if we have seen a union home minister, it is Amit Shah, who has successfully resolved many burning issues of the countries within a few months.

"Shah succeeded in finding a permanent solution to Kashmir issue," Yediyurappa said.
