Safeguarding human rights everyone's responsibility: Singh

Bengaluru, Feb 27: Karnataka Chief Minister and veteran BJP leader B S Yediyurappa turned 78 on Thursday with Prime Minister Narendra Modi and a host of leaders greeting him.

Modi hailed Yediyurappa as a "hardworking" chief minister and wished him long life and good health, while several state leaders flocked to his residence and greeted the Lingayat strongman.

"Birthday greetings to Karnataka's hardworking CM @BSYBJP Ji. He is passionately working for the state's progress, especially on farmer welfare and rural development. I pray for his long life and good health," the Prime Minister tweeted.

A large-scale "non-partisan" birthday bash will be held here later in the evening.

The felicitation function will see Defence Minister Rajnath Singh and former chief minister S M Krishna besides Siddaramaiah of Congress and H D Kumaraswamy of JD(S) sharing the stage.

Union Ministers D V Sadananda Gowda, also a former chief minister, Pralhad Joshi and Suresh Angadi will be in attendance.

BJP National General Secretary (Organisation) B L Santosh and state party chief Nalin Kumar Kateel are among those who will be gracing the event.

While Santosh will release a felicitation volume in Kannada with 78 articles from a cross-section of people, including politicians, writers, bureaucrats, and spiritual leaders; Siddaramaiah and Kumaraswamy will unveil a coffee table book and documentary respectively.

Yediyurappa, on the eve of his birthday on Wednesday, had said whatever he has achieved is a result of the people's "blessings and faith" and requested well-wishers not to bring bouquets, flowers, shawls, sweets, turbans or any souvenirs to greet him.

The birthday function organised by "Yediyurappa Abhinandana Samiti" (Yediyurappa Felicitation Committee) is being seen in some quarters as an attempt by Yediyurappa and his loyalists to send a message to the party leadership that he was still "strong".

The BJP's current dispensation under Narendra Modi and Amit Shah has retired several senior party leaders who crossed the age of 75.

However, an exception was said to have been made in Yediyurappa's case after the BJP won 25 of 28 seats in the Lok Sabha election under his leadership.

In the 2018 elections, he spearheaded the campaign of the BJP which emerged as the single largest party but fell short of the majority mark following which Congress and JD(S) came to power stitching a post-poll pact.

However, the coalition collapsed in July last year, paving the way for return of Yediyurappa as Chief Minister for the fourth time.

Bengaluru, June 23: A head constable from Karnataka State Reserve Police (KSRP) committed suicide on board a bus after testing positive for COVID-19 in the city.

As per sources, the 50-year-old head constable had tested positive for coronavirus last evening and today he was being taken to a hospital in KSRP bus.

It is learned that he hanged himself to death inside the bus as there was no one else.

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
