Businessman killed in road mishap

Bengaluru, Jun 11: Chief Minister BS Yediyurappa on Thursday allowed the Opposition Congress party's newly elected state president DK Shivakumar to have a formal swearing-in function.

He told media, “I have spoken to Shivakumar and informed him to conduct the event after taking precautionary measures against the spread of the COVID-19 disease”.

The move came after the state government received flak from the main Opposition Congress leaders, for refusing to permit the newly elected State Congress president to have a formal swearing-in function take reigns from his predecessor Dinesh Gundu Rao.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Feb 12: Karnataka Sanghatanegala Okkoota, a congregation of various pro-Kannada organisations, has called for a state-wide bandh in Karnataka on Thursday (13 February 2020) demanding reservation in jobs for Kannadigas in both government and private sectors.

The Karnataka bandh, which will begin from 6 am to 6 pm, is likely to impact life in Bengaluru as well as in other parts of the state. Interestingly, Ola and Uber drivers have also extended support to the bandh. 

In Bengaluru, some other drivers’ associations, including Jai Bharatha Vehicle Owners and Drivers Association and Adarsha Auto and Taxi Union have also supported the bandh.

It is not yet clear as to whether the Karnataka State Road Transport Corporation (KSRTC) staff and workers associations will back Thursday’s bandh.

Several other organisations like the Karnataka Film Chamber of Commerce (KFCC), Centre of Indian Trade Unions (CITU), and Lorry Owners Association have supported the February 13 bandh.

In view of the bandh call, schools, colleges and hospitals across Karnataka are likely to remain closed on Thursday.

The Sarojini Mahishi report, which in 1984 suggested that Kannadigas should be given some reservation in jobs in private companies, public sector undertakings and multinational companies, is yet to be implemented.

It is to be noted that Sarojini Mahishi, a four-time MP and Janatha party leader, was appointed by the Ramakrishna Hegde government to head the panel in 1983. The committee submitted an interim report in June 1984. However, a final report was tabled in December 1986 with 58 recommendations, of which the Karnataka government had accepted 45.
