Ayodhya solved; now we'll settle Bababudangiri dispute too: CT Ravi

Bengaluru, Apr 18: Karnataka Congress president DK Shivakumar on Saturday appealed to Prime Minister Narendra Modi to deposit at least Rs 10,000 in bank accounts of people belonging to the unorganised sector.

"The unorganised sector comprises barbers, dhobi, cooks, carpenters, sweepers, drivers and autorickshaw drivers. Prime Minister Narendra Modi did not mention anything about giving subsistence to these people," Shivakumar, told ANI, referring to the Prime Minister's address earlier this week.

Modi had announced the extension of the ongoing nationwide lockdown till May 3 in order to curb the spread of coronavirus.

"I appeal to Prime Minister Modi to register the members of the unregistered sector under the National Rural Employment Guarantee Act (NREGA) or deposit at least Rs 10,000 to the bank accounts of each of the members of unorganised sector to help them survive the lockdown," he added.

Though the Congress party will continue the central government and state government's fight against coronavirus, he said, both the governments need to help people who are part of the unorganised sector.

"The farmers have told me that due to the lockdown they are ready to sell the vegetables, which once used to be sold at Rs 100 per kg, at even Rs 5 per kg," he said.

Speaking on the suggestions he made to Chief Minister BS Yediyurappa, Shivakumar said, "I requested the Chief Minister to send a team to do a videograph and make an assessment of the on-ground situation. However, till now, no one has gone."

Dharwad, Jan 5: Hameed Khan, a noted sitar exponent and descendant of renowned sitarist Ustad Rahimat Khan, passed away at his residence here on Saturday night.

He was 69 and survived by wife Fareeda, son Mohsin Khan (a musician) and daughter Arma Khan (an artist).

Hameed Khan taught sitar at Karnatak University’s college of music and also at the family-run music school ‘Bharateeya Sangeeta Vidyalaya’. Several of his disciples who were foreign nationals helped him establish ‘Kalakeri Sangeet Vidyalaya’ at Kalakeri village near Dharwad, which provides music lessons to the deprived.

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
