Like Bajrang Dal, many Muslims have sacrificed lives for cow protection: RSS chief

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bellari, Feb 23: Fringe outfit Sri Ram Sena leader Sanjeev Maradi said on Friday said that organization will reward Rs 10 lakh to the person who will 'eliminate' those who have raised "pro-Pakistan" slogans including Amulya who recently raised "Pakistan Zindabad" slogan at an anti-CAA protest in Bengaluru.

"We request both state and central government not to release them (Pro-Pakistan sloganeers) on bail. If they will be released Sri Ram Sena will eliminate them or will give a reward of Rupees 10 lakh to those who kill them," said Sanjeev Maradi.

"We condemn such slogans. This is like a virus. First, it happened in Jammu and Kashmir, then in JNU, then Mysore and then a student named Amulya raised pro Pakistan slogan in Bengaluru," he added.

A girl named Amulya raised 'Pakistan Zindabad' slogan on Thursday at an anti-CAA protest where AIMIM chief Asaduddin Owaisi was also invited.

Thereafter, a case was registered under Section 124A (Offence of sedition) of the Indian Penal Code against the student.

Meanwhile, Imran Pasha, the organizer of the anti-CAA protest said that Amulya was not invited to the event.

"We were the organizers of the event. At around 6:45 pm on Thursday, when I and Member of Parliament Asaduddin Owaisi were entering the stage area, we did not notice Amulya was present there. I did not invite her," Pasha told media.

Hubballi, Jan 28: Charting that the Bharatiya Janata party’s Central leaders have not given a free-hand to the Chief minister B S Yediyurappa on the issue of expansion of Cabinet, former Chief minister and the Congress leader Siddaramaiah had opined that 'it has hampered the State’s development'.

Speaking to newsmen here on Tuesday, the Congress leader, alleged that 'by not giving permission to Yediyurappa to expand his ministry, it was evident that there is no any internal democracy in the Saffron Party'.
