IGP Abdur Rahman quits IPS over communal, unconstitutional CAB

Kalaburagi, Jan 1: Fighting penury and partial blindness in one eye, a 39-year-old part-time Kannada lecturer from Kalaburagi district is set to become a commercial tax officer after cracking the Karnataka Administrative Services.

Ambadas Kamble, from Kotana Hipparaga village in Aland taluk, had to take a three-year gap during his school and college years - one-year break after completing Class VII and two years to clear subjects after he failed in II PU examinations. During those three years, he joined his brothers in masonry work to supplement the family's income.

Sweeping aside all hurdles with grit and determination, Ambadas studied Kannada literature for both undergraduate and postgraduate to land the post of a part-time lecturer in a Kalaburagi college. His father died when he was a child, and mother Chandamma supported her family of six - besides, Ambadas, she has two sons and two daughters - by working in houses in the neighbourhood.

Ambadas said he would like to dedicate his success to his mother, who died in the year 2012. "My mother encouraged me to chase my dream - financial difficulties notwithstanding - and allowed me to spend time in the library when my siblings were busy doing menial jobs to fund my education. I'm grateful to my brothers too," he said.

His two brothers are working as masons in Mumbai, having quit studies midway and deciding to support Ambadas - the first in the family to complete graduation. He did high school at Tadkal village in Aland taluk, and college in Kalaburagi.

The lecturer, who's 40% blind in the right eye, cracked the KAS examinations in his third attempt and stood 706th in the state. He has been selected for first-grade officer's post. Alongside, he's doing PhD in Kannada literature.

When his efforts finally paid off, Ambadas landed four job offers: Hostel warden at Morarji Desai hostel, at an SC/ST hostel, post of a lecturer and the tax officer's post. He picked the fourth to serve the state in right earnest.

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

Mangaluru, Jan 7: The city police arrested a youth on charge of spreading messages against political leaders through WhatsApp and allegedly issuing life threats warnings against them.

The accused has been identified as Anwar, a resident of Peruvai village in Bantwal taluk of Dakshina Kannada. He was working in Qatar.

On Monday, Yathish from Vittal filed a complaint and based on that police arrested Anwar.
