Yettinahole project: Activists ask DVS, Moily to pass truth test in Dharmasthala

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Feb 10: After many twists and turns, veteran Congress leader Mallikarjuna Kharge is emerging as the frontrunner for the KPCC president’s post, party sources revealed.

Though the names of DK Shivakumar and MB Patil did the rounds sometime ago, the party high command could not decide on an apt candidate, and had to widen its horizon looking for a leader who can take all factions along, and they seem to have zeroed in on Kharge.

But the senior Dalit leader is also in the reckoning for the more important All-India Congress Committee president’s post after he successfully stitched up an alliance, despite all odds, between the Congress and Shiv Sena in Maharashtra. He is understandably reluctant to take up the KPCC post. “The central leadership has given him some time to consider the KPCC offer,” the sources said.

The high command would rather go with Kharge as he is politically a far bigger force than Shivakumar and M B Patil and the party central leadership wants a safe pair of hands to handle the affairs of the state, the sources said. Also, senior leaders Siddaramaiah, Shivakumar and M B Patil cannot raise a voice against Kharge if he is elected to the post, they said.

Kharge was the Pradesh Congress chief in 2008 when the BJP was in power under B S Yediyurappa. An old warhorse, Kharge is seen as an able administrator and taskmaster. He had won a record 11 elections on the trot before he was defeated in the Kalaburgi Parliamentary Constituency by his former protege Dr Umesh Jadhav in the last election.

Sources said that the high command will not consider Shivakumar for the top slot till he comes out clean in all the legal cases against him.

It is exactly two months since Dinesh Gundurao resigned as KPCC president after the party managed to win just two out of the 15 Assembly constituencies that went for by-elections. Siddarmaiah too resigned on the same day owning moral responsibility for the loss, but the party has decided to continue with him as the assembly opposition leader, while looking for a replacement for Gundurao. 

The high command sent senior central leaders  Madhusudhan Mistry and Bhakta Charan Das on December 20 to sort out the issue of KPCC president. Though they met the state leaders and held high-level meetings in Delhi, they could not decide on a candidate. Meanwhile, the central leadership has asked Gundurao to continue in the post, till a replacement is found.

‘Congress will protest against scrapping reservation’

Bengaluru: “RSS-BJP is against reservation and have been trying to scrap it for sometime now,’’ said senior Congress leader Mallikarjun Kharge on Sunday. He stated that the Congress would take up the issue for a determined agitation both inside and outside the parliament. He said they must file a petition against this. His reaction comes after the SC recently took a decision where the top court had maintained that reservation in promotions was not a fundamental right.

Bengaluru, Jul 16: Karnataka chief minister BS Yediyurappa on Tuesday said he would request Prime Minister Narendra Modi for more relaxations, as he made it clear that Covid-19 lockdown measures were not required in the state anymore.

"The lockdown is not required for Karnataka, we will request for more relaxations," Yediyurappa said in response to a question about video conferencing with the Prime Minister.

Speaking to reporters here, he said, "I will request him (PM) to make way for- people to lead a normal life and for the improvement in the economic situation."

Several services such as metro, theatres, gyms, swimming pools, bars among others continue to remain restricted under unlock 1.0 that is currently in place.

Modi is scheduled to hold a video conference with chief ministers of various states on Tuesday and Wednesday. Yediyurappa is scheduled to take part in the video conferencing on Wednesday.

The chief minister, who took part in the special pooja organised at Shankar Math here to pray for the control of Covid-19, said, the government was making all efforts to control the spread.

"We are taking strong measures and all of us should fight this together," he said, as he highlighted that the government has released the financial assistance amount that was announced for farmers, and was ensuring that it reaches them.
