Muthalik, others booked for staging protest at Bababudan Dargah

Bengaluru, Feb 26: Karnataka Minister CT Ravi on Wednesday said that time is ripe to bring in Uniform Civil Code in the country as there was a demand for "equality".

"Everyone talks about equality. Those who desired inequality in the past are now seeking equality. The time is ripe to bring Uniform Civil Code," he said.

The Minister said that the Uniform Civil Code (UCC) has been a part of the party's agenda since the time when BJP was formed in 1980.

"We spoke about article 370, we have done it, on Ayodhya issue, the Supreme Court has given its verdict. As the time comes we will do it," he said.

Mangaluru, Mar 27: Nine throat swab samples that were sent for testing of the coronavirus, have been declared as negative while samples of four more persons are currently being tested, official sources said on Friday.

Dakshina Kannada Deputy Commissioner Sindhu B. Rupesh said that 2,902 people are under home quarantine in the district as of today while three were admitted to hospitals for observation.

Around 38,051 people have been inspected, so far, here in this district.

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study
