Minister Khader gets a rousing reception in Mangaluru

Bengaluru, Apr 16: Karnataka Deputy Chief Minister Dr Ashwath Narayan today said that if former chief minister HD Kumaraswamy, being a law-abiding citizen, does not follow guidelines then action will be taken against him.

The Deputy CM made this comment when he was asked about Kumaraswamy's son Nikhil's marriage, which has been fixed on April 17 at a farmhouse near Bidadi in Ramnagar.

Narayan said: "Any violation of the guidelines will not be tolerated. We will ask the concerned authority to film the entire event and document it."

He said that so far Kumaraswamy has made public statements that guidelines will be followed.

"HD Kumaraswamy is a people's representative. He has been in public life for a long time. He should abide by the guidelines," Narayan said.

"Since he has been in a responsible position for a long time and he was the Chief Minister, guidelines must be followed in his son's marriage as per the rules amid COVID-19 scare.

After the marriage, there must not be any excuses. He cannot say that people came without an invitation," the Deputy Chief Minister added.

Kumaraswamy clarified that only his family members will attend the marriage and that there will be around 60 to 70 people.

"All guidelines will be followed as per the central government directives," he said.

Mangaluru, Jan 17: An auto-mobile shop at Deralakatte here caught fire on Friday incurring huge loss on the shopkeeper.

According to police, the incident happened in the morning when the shop owner opened the shop.

Locals suspect that miscreants might have set the shop on fire and had escaped from the scene at night.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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