Yes, we will implement the Citizenship Amendment Act in Karnataka: Yediyurappa

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Mar 23: Film producer, philanthropist and entrepreneur V K Mohan committed suicide by hanging himself in a hotel in the city on Monday, police said.

Mohan, who hailed from Kundapur Taluk, Udupi District, was a famous film producer and hotelier.

According to police, Mohan arrived at the hotel on Sunday night and when he did not open the door of his room on Monday, hotel staffs, grew suspicious and peeped through the room window, found him hanging.

Bengaluru, Jan 16: Senior Congress leader K J George on Thursday appeared before the Enforcement Directorate officials here in connection with a FEMA case.

The former minister is being investigated by the ED for probable violation of provisions of the Foreign Exchange Management Act.

The ED had recently issued summons to George.

Speaking to reporters after appearing before the ED, George said he has answered to the officials' queries and will cooperate further also.

"ED had issued me summons, as a law abiding citizen, I have answered and gave documents to whatever they asked.

Further also if they call me...I will cooperate and provide necessary documents," he said, without divulging any details.

George clarified that no summons has been issued by the ED to members of his family.

"If required they (ED officials) will call me again, and I'm ready to cooperate," the congress leader added.

Last year, the president of the Karnataka Rashtra Samithi Ravi Krishna Reddy had complained to the ED seeking a probe into the alleged money laundering and properties held by George and his family members in the United States.

Responding to a question about a defamation case filed by him against those who have levelled the allegations, George said "Just because ED has called me for questioning, I'm not proved guilty."

"Anyone can complain to agencies like the Income Tax or ED or Lokayukta, but my only objection is with going to the press to project someone as guilty," he said.

"...going to the press with an intention to do a propaganda against me..someone who is in public life-- to project me as guilty is wrong, so I have filed defamation case stating the allegations are false," he added.

George is the third senior Congress leader from Karnataka to face an ED probe after D K Shivakumar and B Z Zameer Ahmed Khan.

Shivakumar was arrested by the agency in a money laundering case and was kept in Tihar Jail, until he got bail in October, while Khan was summoned in connection with the multi-crore IMA group Ponzi scam case.
