Congress suppressing patriots, holding meetings with terrorists: Anant Kumar Hegde

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

New Delhi, Apr 29: Karnataka is likely to withdraw the case filed against a CRPF commando who was arrested by state police officials for alleged assault on them during COVID-19 lockdown duty in Belgaum, a charge contested by the paramilitary Central Reserve Police Force.

In a bid to diffuse the ongoing tussle between CRPF and Karnataka police, the official communication sent to CRPF headquarters on Tuesday, with the details of bail granted to CRPF jawan Sunil Sachin Sawant, stated that the issue was discussed with the DGP Karnataka and other senior state authorities with a request to withdraw the case.

According to official communication, Karnataka Director General of Police has assured top CRPF officers that the "case registered against CRPF CoBRA commando is likely to be withdrawn by the state authorities".

The communication also states that "they assured that the criminal case registered against constable of 207 CoBRA BN is likely to be withdrawn by the state authority."

A CRPF CoBRA commando was thrashed and dragged to police station barefoot by police on April 23 for allegedly violating lockdown norms and assaulting/deterring public servant from discharging his duty in Belgavi district of Karnataka. A case was also registered against him.

This is not the first time when the state is showing efforts to solve the matter amicably.

Karnataka culture and tourism minister CT Ravi had also tweeted on April 27 claiming that he had a word with two ministers including state deputy chief minister who 'confirmed that the issue will be resolved amicably'

"Unfortunate that this incident happened with a CRPF Commando and the police. I have spoken with Industries Minister @JagadishShettar and Transport Minister @LaxmanSavadi. Both have confirmed that the issue will be resolved amicably," CT Ravi had tweeted.

CRPF Additional Director General (ADG) Sanjay Arora had also written to DG showing his displeasure over the ill-treatment done by Karnataka police with CRPF jawan and had said that "Keeping in view the gravity of the incident and its impact on the relationship between the two police forces, I am desired by the Director-General CRPF to request you to kindly get the matter inquired and provide justice. We would be thankful if you could inform us of the outcome."

Arora, in his letter, had also said that Karnataka police should have informed the force before registering a case.

The CRPF CbBRA commando was on extended leave and cleaning his motorcycle in front of his house in Examba city when he was allegedly manhandled and ill-treated in front of his family members and paraded to the police station barefoot, where he was kept in chains and handcuff.

The commando was granted bail by a court on Tuesday in the matter.

Sunil Sachin Sawant has been involved in various anti-Naxals operations and is a part of the CRPF elite CoBRA force, which is famous for doing anti-Naxals operations and has eliminated hundreds of Naxals in the past few years.

Bengaluru, Mar 21: Karnataka Deputy Chief Minister CN Ashwath Narayan on Saturday said that all the IT companies in the state have agreed to close their offices and have also allowed some employees to work from home in the backdrop of the coronavirus pandemic.

"IT companies agreed to close their offices and allow employees, except for those discharging essential services, to work from home during a video conference with companies' representatives yesterday," said Narayan.

The Deputy Chief Minister said a circular regarding it will be issued soon.
