Pakistani model killed by brother for posting semi-nude selfies on social media

Mysuru, Jan 28: The Second Additional District and Sessions Court on Monday granted anticipatory bail to B Nalini, who displayed the ‘Free Kashmir’ placard during a protest, and also to Maridevaiah, the organiser of the protest.

Nalini and Maridevaiah had applied for bail as Jayalakshmipuram police had booked them under sedition charges. Nalini had displayed the placard during a protest at Manasagangotri, the University of Mysore campus, recently. The court, which took up the case on January 24, had kept the order pending.

The court directed the accused to submit their passport to the court and a bond for a sum of Rs 50,000. The court also directed them to be present before the police, whenever needed.

Meanwhile, the Mysuru Bar Association has decided to take measures against the association members who are in favour of Nalini. Seventy-five members, seeking to represent Nalini, have withdrawn their support, the association secretary B Shivanna said. The association has suspended advocates Manjula Manasa and P P Baburaj.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 8: 45 more COVID-19 cases have been reported from Karnataka, taking the total number of coronavirus cases in the state to 750, the state Health Department said on Friday.

According to the Health Department, the total cases include 371 discharged cases and 30 deaths.
