‘Why job? Join anti-CAA protest, eat free Biryani’: Dubai’s NRI employer Gokhale’s response to job seeker Abdulla

Mandya, Feb 9: A youth from Arechakanahalli village of Maddur taluk on Saturday allegedly committed suicide in Bengaluru after his lover got engaged to another man.

The body of the deceased, Darshan, was found hanging from the celising of his room in Bengaluru. According to Darshan's relatives, he was in love with a girl for the past few years.

Darshan had wanted to marry her, much to the chagrin of her parents, it is said.

The girl's parents had allegedly warned him of dire consequences if he did not stay clear from their daughter. In the meanwhile, she got engaged to another man.

Feeling left out, Darshan allegedly ended his life. In the suicide note, Darshan has held his lover and some of her relatives responsible for his death. He has also claimed that his family was facing death threat from her family.

There are rumours that Darshan might have been killed after he refused to stop seeing the girl. Though both the families are from the same community, their financial status, sources said, is different.

According to the relative of Darshan, the girl is a close relative to a former minister from Mandya district.

"There are reasons to suspect that Darshan might have been murdered, and a suicide note may have been planted at the crime spot.

A proper investigation should be conducted to unearth the truth," he said.

Kasaragod, Apr 24:  Stricter measures have been enforced in more places in this district, as part of intensifying efforts aimed at containing the spread of Covid19.

According to District Collector Dr Sajith Babu, the new norms of intensified lockdown would be enforced in Kumbala, Mogral-Puthur, Chemmanad, Madhur, Muliyar and Kumbala grama panchayats, being identified as new hotspots in the district.

Earlier, door-to-door police patrolling at regular intervals have been implemented in Thalankeri, Choori, Kalanad and Nellikkunnu, where more positive cases of Covid-19 has been reported.

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
