Mysuru, Feb 7: Former chief minister and Janata Dal (Secular) leader HD Kumaraswamy on Thursday said that Chief Minister BS Yediyurappa-led government is not stable and it can fall at any moment.

"Karnataka Government is not a stable one. With the developments taking place, it can fall at any moment," Kumaraswamy told reporters when asked to comment on the Karnataka Cabinet expansion.

Earlier in the day, 10 MLAs including Ramesh Jarkiholi, Anand Singh, K Sudhakar and BA Basavaraja took oath as Cabinet Ministers at Raj Bhawan in Bengaluru.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Udupi, June 21: An entrepreneur lost his life after the car he was driving veered off the road and plunged into a roadside tank near Barkuru in Brahmavar taluk of Udupi district today.

The deceased has been identified as Santosh Shetty, a resident of Vakwadi in Kundapur taluk. He is the proprietor of Laxmi Glass and Plywood, Koteshwara.

The mishap occurred when the duo was heading to Vakwadi from Brahmavar in Hyundai Car sedan car. 

Shetty lost control over his vehicle while negotiating a curve at Chaulikere and the car plunged off the road as there was no barricade. 

Even though local residents began rescue operation immediately, Shetty breathed his last on the spot. Shweta was rescued and shifted to a hospital in Manipal for treatment.
