Mangaluru, Jul 11: Deputy Commissioner Sindhu B Rupesh has set up an expert committee to look into the cause of deaths of covid patients in Dakshina Kannada.

The development comes after eight more fatalities including that of a CISF personnel attached to MRPL, were reported in the district on Friday.

The district has recorded 23 deaths since July 1 and 38 death cases have been reported in the district since April 19.

Of the 38 deaths, five were from outside the district. All the eight patients, who lost their battle to the virus in the district on Friday, were suffering from co-morbidities.

According to the govt bulletin on Covid-19 cases, comorbid conditions, like kidney failure, brain tumour, TB, pneumonia, liver damage, high BP, diabetes and others, were the main reasons behind the Covid-19 deaths reported in the district.

Bengaluru, Jan 24: Karnataka High Court on Friday ordered notice to the state government and self-styled godman Swami Nithyananda while hearing a petition seeking cancellation of bail granted to him.

A petition was filed in the Karnataka High Court on Friday seeking cancellation of bail granted to Nithyananda for skipping the trial and fleeing the country.

Justice John Michael Cunha, after hearing the complainant, ordered issuance of notice to the state government and Nithyananda and posted the matter for hearing next week.

The petition, filed by K Lenin, alleged that Nithyananda has been skipping trial and has fled the country on an expired passport.

The plea further said that Nithyananda was making false representations in his "exemption petitions to the trial court as if he is still in India".

Interpol has also issued a 'blue corner notice' to locate the self-styled godman, who is facing trial in a criminal case, on the request of Gujarat Police. 

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.
