Vatal to form Karnataka Praja Samyukta Ranga, to field candidates in Assembly polls

Bengaluru, Feb 26: The police remand of student activist Amulya Leona Noronha, who was produced before a Magistrate, after a no-show at the Metropolitan Magistrate Court, was extended by 10 more days.

The Fifth Additional Metropolitan Magistrate at the Magistrate's home on Tuesday night had remanded her to police custody for 10 days, less than the 14 days asked for by the Special Investigative Team, considering that she has already spent over four days in judicial custody.

Amulya Noronha, a student of NMKRV College for Women, had raised pro-Pakistan slogans by shouting ''Pakistan Zindabad'' at an anti-CAA protest in Bangalore on 20th February following which the city police filed a case of sedition against her.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Tumakuru, Jan 8: RSS leader Kalladka Prabhakar Bhat stoked controversy on Wednesday by stating that 'Jawaharlal Nehru University (JNU) is full of traitors'.

He was addressing the media after taking part in a pro-CAA rally organised by National Citizens Forum near the office of the deputy commissioner of the district here.

Bhat said, “JNU is full of traitors. Congress and communist parties have been generating anti-nationals there. But there is no need to close the university down. Modi government will handle it.”

“Nationalism should be infused among the students there through love and trust. They should be made to realize what the truth is,” he said.
