BJP's victory celebration takes a violent turn, 1 killed in clash with Cong workers

Bengaluru, Jun 3: Kempegowda International Airport in Bengaluru on Tuesday intensified preventive measures to contain the spread of COVID-19 in a bid to make air-travel contactless.

The airport has introduced contact-less self-check-in kiosks, non-intrusive thermal cameras, self bag drop facility and other features.

Bangalore International Airport Limited (BIAL) had earlier said that it will ensure that the taxis are sanitised and the drivers are screened before every trip to eliminate all chances of infection.

"Drivers have been instructed to maintain a safe distance. They will be encouraged to use hand sanitiser and face masks to make the car a safe space. Able-bodied passengers are advised to load their luggage into the car without the driver's assistance. For elderly citizens and passengers with reduced mobility, drivers will assist while following hygiene measures," BIAL statement had said.

The masks have been made mandatory for both drivers as well as passengers.

Karnataka on Monday reported 187 new cases of coronavirus, with which the State's total COVID-19 count has surged to 3,408.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Hubballi, Jan 15: Leaders of the Muslim community, Dalit organisations, Congress Party, and others are staging a hunger strike at Dr B R Ambedkar Circle in Hubballi, opposing the Citizenship Amendment Act (CAA) and National Register of Citizens (NRC).

Raising slogans against Prime Minister Narendra Modi and Union Home Minister Amit Shah, they demanded the withdrawal of the CAA and not to implement NRC.

"India is witnessing such a dictatorship for the first time. The BJP government is trying to divide people into the lines of religion, through CAA and NRC. This move is a threat for peace and harmony in the country," said AICC member Shakir Sanadi, who led the protest.

Sayed Tajuddin Quadri, Moulana Niyaz Alam, Moulana Nayimuddin and others took part in the hunger strike.

Former minister A M Hindasgeri, former MP I G Sanadi, F H Jakkappanavar, Pitambrappa Bilar, and others also extended support to the protest.
