BJP demands white paper on Karnataka’s finance position as HDK govt completes 6 months

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, Jun 10: Janata Dal-Secular (JD-S) supremo and former Prime Minister H.D. Deve Gowda said on Tuesday that he filed his nomination for the June 19 Rajya Sabha elections from Karnataka in response to a collective call from national leaders to be back in the Parliament.

"Though I was not personally interested to contest, national leaders from Congress President Sonia Gandhi, National Conference President Farooq Abdullah, TMC and Left parties want me back in Parliament," he told reporters here.

Gowda, 87, filed his nomination in the Vidhana Soudha, submitting the papers to Assembly Secretary and Returning Officer M.K. Vishalakshi, a party official told IANS.

Gowda''s second son and former minister H.D. Revanna and third son and former Chief Minister H.D. Kumaraswamy were present on the occasion.

"Our party''s all 34 legislators also urged me to contest as my presence is necessary in Parliament at a time when the country was grappling with multiple crises in the aftermath of coronavirus," said Gowda.

Claiming that there was no pressure from his two sons as they are more concerned with his health, Gowda said he was touched by the requests of the national leaders, especially Gandhi who personally called him and asked him to contest as the country needed his presence in Parliament.

Gowda agreed to contest in the bypoll as his party''s candidate after the Congress state unit assured him of its support with its surplus votes, as the JD-S with 34 legislators is short of 10 votes of the required 44 votes.

It will be second time Gowda will enter the Rajya Sabha, 24 years after he was its member as the Prime Minster from June 1996 to April 1997 of the United Front government.

"Congress General Secretary K.C. Venugopal informed Kumaraswamy on June 6 that the party was fielding only its senior leader Mallikarjun Kharge from Karnataka and had surplus votes to ensure my victory as our party is 10 votes short of the required 44 votes to win," Gowda said.

Kharge filed his nomination on Monday.

Party''s outgoing member Kupendra Reddy, whose 6-year term ends on June 25, told Gowda that he was not interested for a second term as he did not get enough time in the upper house to raise issues.

"As our party does not have numbers in Parliament to get more time allotted to raise issues and participate in debates, Reddy wanted me to be in the Rajya Sabha in his place so that I could serve the nation better," Gowda said.

Gowda lost in the May 2019 general elections from Tumkur to G.S. Basvaraj of the BJP.

With the term of the four members -- Congress'' B.K. Hariprasad and Rajeev Gowda, BJP''s Prabhakar Kore and JD-S''s Reddy ending on June 25, the Election Commission notified the poll on June 1.

According to the poll panel, the nominations will be scrutinised on Wednesday and last date for withdrawal by candidates is June 12. Polling and vote count is on June 19.

From the ruling BJP, its grassroot cadres Eranna Kadadi and Ashok Gasti filed their nominations after Gowda.

By fielding Gowda for the fourth seat, the Congress and JD-S, who had post-poll and pre-poll alliances for the Lok Sabha and state Assembly elections in May 2019 and May 2018, queered the pitch for the BJP, denying it the chance to win a third seat.
