Two Leftists injured as suspected RSS activists hurl bomb

Chikkamagaluru, Jan 19: A Chikkamagaluru court on Saturday were sentenced to death two persons convicted of rape and murder 18-year-old girl in 2016.

Pradeep M, 32, and Santhosh, 24, of Vykuntapura in Sringeri taluk raped a 18-year-old girl while she was returning home from college on Februrary 16, 2016.

The crime in which a first year B.Com student who was walking towards her home in a footway was stopped, raped and murdered by the duo. The killers then had dumped her body in a discarded well.

Kasaragod, Apr 6: Even as the number of positive cases of Novel Coronovirus is on increase in this district, the ten-member medical team from Thiruvananthapuram on Monday will inspect and review modalities to convert the proposed Kasaragod medical college into a COVID-19 hospital.

Given the constraints being faced by the district hospital in Kanhangad near here, the 200-beded Kasaragod medical college hospital in Ukkinada near here would be equipped to cater to the Covid-19 patients on isolation.

The ten member medical experts who reached here late on Sunday, are on a special mission to immediately equip the hospital as to convert it as a Covid-19 centre.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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