Newsroom, Jun 16: A 35-year-old Kannada lecturer died in a motorbike accident at Tumkuru in Karnataka.

The deceased is K N Swamy, who was a guest lecturer in Department of Kannada at Central University of Kerala located at Periya in Kasaragod district.

The accident occurred on Sunday afternoon when he was riding his motorbike.

Swamy was also a writer and poet in Kannada.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jan 5: BJP leader and Karnataka Chief Minister BS Yediyurappa once again blamed the Congress of creating 'confusion' among the Muslim community over the Citizenship (Amendment) Act-2019 while launching a door to door campaign to dispel such rumors.

Yediyurappa was on a door-to-door campaign to make people aware of the Citizenship (Amendment) Act and to allay their fears.

"Unnecessarily, the members of Congress are creating confusion among the Muslim community. I assure you that not a single Muslim will be affected because of CAA," said B. S. Yediyurappa.

"Almost all previous Prime Ministers have supported it, now Congress is creating a problem so as to create confusion among Muslims. That's why we are out on the door-to-door campaign," he said.

The Citizenship Amendment Act, 2019, seeks to grant Indian citizenship to Hindu, Christian, Sikh, Buddhist and Parsi refugees from Pakistan, Afghanistan, and Bangladesh and who entered India on or before December 31, 2014.
