Bunt women called on to recognise their 'shakti'

Bengaluru, Jan 5: B S Yediyurappa-led Karnataka cabinet has finally decided to resume supply of subsidised rice and wheat to students of welfare institutions and hostels including those run by religious mutts under the Dasoha Scheme’s welfare programme. The supply was stopped over two months ago.

“Cabinet has decided to continue supply of subsidised foodgrains (rice and wheat) for the benefit of 37,700 children under the Dasoha scheme in 351 welfare institutions for the next one year at the cost of Rs 18 crore,” said J C Madhuswamy, Law and Parliamentary Affairs Minister. Under this scheme, institutions that provide free accommodation and food for students are entitled to avail 10 kg rice and 5 kg wheat per student every month at subsidised rates. But following a central government directive in November, the state government had stopped supply to private institutions since December.

Hours before the cabinet meeting, Khader addressed a press conference and said, “This government is snatching away food from children by stalling the supply of foodgrains. Institutions like Suttur Mutt, Siddaganga Mutt that have worldwide fame for their service are being inconvenienced by this,” Khader said.

Finding itself in a fix, especially in a matter that involves mutts, the cabinet was quick to restore the supply. “Foodgrains were being supplied to 183 government-run institutions and 281 institutions run by private entities. As per a central government directive, supply to private institutions was stopped but the decision was made by the previous government,” Shashikala Jolle, Women and Child Development Minister, said.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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