Implement loan waive in transparent way: CM Kumaraswamy

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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: Karnataka chief minister BS Yediyurappa on Tuesday shuffled the portfolios of six newly inducted ministers after they expressed unhappiness about the departments allocated to them barely 24 hours ago.

Three ministers — BC Patil, Anand Singh and K Gopalaiah — received new responsibilities and as many — Shivaram Hebbar, Srimanth Patil and Byrathi Basavaraj — have been saddled with more.

Sources said the six ministers met the CM late Monday night and said they were not happy with the portfolios handed to them. They reportedly threatened not to assume office until their demands were met, forcing the CM to effect the changes early Tuesday.

BC Patil is now vested with agriculture (he had been given forest), Anand Singh forest, environment and ecology (earlier food and civil supplies) and Gopalaiah food and civil supplies (instead of small-scale industries). BC Patil said, “I’m happy I can now be with farmers.” Shivaram Hebbar has been given the additional responsibility of sugar along with labour allocated to him on Monday.

Allocation of the forest portfolio to Anand Singh has raised eyebrows as the Vijayanagara MLA had been arrested in 2013 and 2015 in cases of illegal mining and illegal transportation of mining ore. Singh owned SB Mineral in Ballari and the Lokayukta had charged him with transporting 17,086 tonnes of iron ore without permission or valid licence. He was acquitted in a Belikeri iron ore export case due to lack of evidence.

Byrathi Basvaraj, who has been given the urban development ministry, will also handle Karnataka Urban Water Supply and Drainage Board and Karnataka Urban Infrastructure Development and Finance Corporation.

Srimanth Patil has received minority welfare department apart from textile.

The exercise of portfolio shuffling is likely to continue with minister K Sudhakar reportedly unhappy with medical education.

In another embarrassment to the CM, Mahesh Kumathalli on Tuesday refused to take over as chairman of the Mysore Sales International Ltd, saying he wants to be a minister. BJP MLA Basanagouda Patil Yatnal urged Yediyurappa to induct Kumathalli into the cabinet in line with the promise made to him when he joined the BJP before bypolls. “The CM must keep his word,” he said.
