BJP leader criticizes literary fest; letter threatens bomb blast at venue

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, May 6: The second day of liquor sales in Karnataka on Tuesday after easing of lockdown curbs saw a nearly five-fold jump in earnings, with Rs 197 crore worth spirits being sold.

According to top Excise Department officials, 4.21 lakh cases of Indian-made liquor, comprising 36.37 lakh litres, worth Rs 182 crore and 7.02 lakh litres of beer in 0.90 lakh cases worth Rs 15 crore was sold on Tuesday.

On Monday, when sales resumed in the state, Rs 45 crore worth liquor was sold.

"We had never expected such a record sale. It's unprecedented," an Excise official who did not wish to be named said.

Liquor sales had resumed in Karnataka on Monday after a 41 day gap following the lockdown due to the COVID-19 pandemic.

Kottayam, Mar 16: A trial court in Kerala  on Monday dismissed a discharge petition filed by Bishop Franco Mulakkal, in connection with the case of alleged rape of a nun in which he is the prime accused.

In his plea filed before the Additional District and Sessions Court I, Mulakkal had claimed that prima facie there was no case to frame charges against him.

Dismissing the plea, the trial court said the bishop should stand for trial in the rape case.

The bishop's lawyer said an appeal would be filed in the High Court against the trial court order.

The prosecution had filed its objection to the plea filed by the bishop, accused of raping and sexually assaulting a nun of the same diocese.

The bishop had filed the plea just ahead of commencement of the preliminary hearing on charges against him in January this year.

The case is based on a complaint filed against the bishop by the nun.

In her complaint to the police in June, 2018, the nun had alleged that she was subjected to sexual abuse by the bishop during the period between 2014 and 2016.

The bishop, who was arrested by the Special Investigation Team which probed the case, has been charged with wrongful confinement, rape, unnatural sex and criminal intimidation.
