Cong extends Karnataka poll campaign to Saudi Arabia; leaders reach out to NRIs

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, Feb 19: Pointing out that there was a deliberate attempt to cover up police excesses by implicating innocent persons at whim, the Karnataka High Court on Tuesday granted conditional bail to 21 people who were accused by police of involving in violence during the protests against the Citizenship Amendment Act (CAA) in Mangaluru.

Allowing the bail petitions of Ashik and 20 others from Udupi and Dakshina Kannada districts, Justice John Michael Cunha said the overzealousness of the police is also evident from the fact that FIRs were registered under Section 307 of IPC against the persons killed by the police themselves.

“In an offence involving a large number of people, the identity and participation of each accused must be fixed with reasonable certainty. In the present cases, the identity appears to have been fixed on the basis of their affiliation to PFI and they being members of the Muslim community. Though it is stated that the involvement of the petitioners is captured in CCTV footage and photographs, no such material is produced before the court showing the presence of any of the petitioners at the spot, armed with deadly weapons,” the judge noted.

In the statement of objections filed by the State Public Prosecutor-I, it was stated that there was a hint of Muslim youths holding protest on December 19, 2019, opposing the implementation of CAA. Prohibitory orders were clamped in that connection. This assertion indicated that the common object of the assembly was to oppose the implementation of CAA and National Register for Citizens (NRC) which, by itself, was not an “unlawful object”, the judge pointed out.

‘Pics show cops throwing stones at crowd’

Justice Cunha also said the material collected by the investigators did not contain any specific evidence regarding the presence of any of the petitioners at the spot. On the other hand, omnibus allegations were made against the Muslim crowd of 1,500-2,000, alleging that they were armed with weapons like stones, soda bottles and glass pieces. The photographs produced by the SPP depicted that hardly any member of the crowd were armed with weapons, except one of them holding a bottle. In none of these photographs, police station or policemen were seen in the vicinity, the judge noted.

“On the other hand, photographs produced by the petitioners show that the policemen themselves were pelting stones at the crowd. The petitioners have produced copies of the complaints lodged by the dependants of the deceased who died due to police firing and the endorsement made thereon reveals that even though the law required the police to register independent FIRs in view of the specific complaint made against the police officers making out cognizable offences, the police have failed to register FIRs. This goes to show that a deliberate attempt is underway to cover up police excesses by implicating innocent persons at the whims and caprice of the police,” the judge observed.

In the wake of counter-allegations against the police and in the backdrop of their failure to register FIRs based on complaints lodged by the families of victims, the possibility of false and mistaken implication could not be ruled out, the judge said. In these circumstances, it would be a travesty of justice to deny bail to the petitioners and sacrifice their liberties to the mercy of the district administration and police. The records indicate that a deliberate attempt has been made to trump up evidence and to deprive the liberties of the petitioners by fabricating evidence. None of the petitioners have any criminal antecedents, the court said.

“The allegations levelled against the petitioners are not punishable with death or imprisonment for life. There is no direct evidence to connect them with the alleged offence. The investigation appears to be malafide and partisan. In the circumstances, in order to protect the rights and liberties of the petitioners, it is necessary to admit them to bail,” the judge said.

The petitioners were arrested and remanded in judicial custody after the anti-CAA protests on charges of being members of an unlawful assembly, armed with lethal weapons, attempting to set fire to the North Police Station in Mangaluru, obstructing the police from discharging their duties and causing damage to public property, etc., on December 19 in violation of the prohibitory orders. They moved the High Court as their bail pleas had been rejected by a sessions court in Dakshina Kannada.

Mangaluru, April 3: A police officer in Sullia town of Dakshina Kannada district got injured on Friday after unidentified youth pelted stones at him.

The incident took place when the cop stopped them from entering into the state from Kerala in the view of nationwide lockdown. He was later administered medical aid.
