5 saffron extremists including a Mangalurean are key suspects in Gauri Lankesh murder

Mangaluru, Apr 22: Iftar parties, Taraweeh and weekly Friday prayers in mosques have been banned in the district during Ramadan amid Coronavirus theat, Dakshina Kannada Deputy Commissioner Sindhu B Rupesh said here on Wednesday.

In a release issued here, she said, “As per the guidelines issued by the State government and Wakf Board, arranging Iftar gathering, and offering Taraveeh Namaz and Friday Namaz at mosques or dargas during the month of Ramadan has been prohibited as a precaution measure to prevent the spread of coronavirus. Therefore, offer prayers at homes instead of going to mosques," the DC said.

“No one can perform Namaz in the mosques except the muezzin and the Pesh imam and the staff of the mosque. Also, gathering neighbors and offering collective prayers at anybody's home is also not allowed. Masjid administration committees must follow the directives of the government, Wakf Board and the District Administration”, the DC urged.

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, Jul 26: The government of Karnataka has urged the Muslims to celebrate Eid al-Adha in a simple manner and follow all guidelines amid mounting cases of covid-19.

The festival, also known as Bakrid, will be celebrated on July 31 in coastal districts of Karnataka and on August 1 in other parts of Karnataka. 

In an order, A B Ibrahim, secretary of the department of minority welfare, Hajj and Waqf has prohibited offering Eid prayers in open grounds (Eidgahs) in the wake of pandemic.

Eid prayers can be offered in mosques by following all the necessary precautionary measures including maintaining physical distance. The congregation should not exceed 50 worshippers. If they number exceeds, they should be divided into three groups. 

However, except for mosques, no other places should be used for offering congregational prayer. 

Besides, all those who attend Eid prayers at mosque should compulsorily wear face masks. Entry is banned for people who are above the age of 60 years and below the age of 10. At least six feet distance needs to be maintained while offering prayer.

Thermal scanning needs to be done before entering the mosque. Hands need to be washed in soap or sanitizer. No one should touch the holy books in the mosque. Hand shaking and embracing to greet will also not be allowed. If any strangers are seen, their movement should be monitored.
