Bengaluru, Jan 6: A delegation of Christians, led by Peter Machado, archbishop of Bengaluru, met chief minister BS Yediyurappa on Sunday and sought an amicable solution to the issue of installing a statue of Jesus Christ atop Kapalibetta in Harobele village, Kanakapura taluk.

Yediyurappa is learnt to have assured the delegation of doing the needful and said he would take a decision after the revenue department submits its report. The department is looking into various aspects of the issue, including the sanction of 10 acres of land for the purpose.

“The meeting was cordial and the chief minister lent us a patient hearing. Our only request was to settle the issue in a way that is acceptable to all sections of society,” Machado said. Congress functionary and Kanakapura legislator DK Shivakumar had laid the foundation stone for the 114-foot statue of Christ on Kapalibetta on Christmas Day at an event organised by the Harobele Kapalibetta Development Trust, which plans to install the statue.

The issue took a political hue when BJP functionaries objected, saying the land sanctioned to the trust is part of gomala (reserved for cattle grazing) land and any religious activity there would be illegal. Revenue minister R Ashoka sought a report and department officials said they would submit it in a week’s time.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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