Makkah Imam pulls unprecedented crowds in Karnataka

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Shivamogga/Hubballi, Feb 10: Chief minister BS Yediyurappa on Sunday reiterated portfolios for all new ministers will be distributed on Monday and the exercise was not completed sooner only because of weekend holidays.

“I had completed all the formalities on the portfolio allocation,” Yediyurappa said, appearing to rubbish rumours that the delay was caused due to a tussle over portfolios. “However, considering it was a weekend, I decided to postpone handing them out. On Monday all portfolios will be announced.”

The CM also promised to induct loyalists into his council of ministers, admitting Umesh Katti, Hukkeri legislator, should not have been left out. Speaking in Shivamogga earlier in the day, Yediyurappa said Katti was scheduled to take oath last week along with the 10 defectors, but the decision was scrapped at the last minute due to “unavoidable reasons”. “But I have discussed the issue with Katti. Considering he is from North Karnataka and that we have worked together for many years, he will be included in the cabinet soon,” Yediyurappa said.

When questioned on more prominent legislators from his home district missing out — especially Thirthalli Arag Jnanendra — he said a “different responsibility” has been given to him and has already explained why he could not be inducted.

Yediyurappa refused to react to comments by former chief ministers Siddaramaiah and HD Kumaraswamy on government’s survival, saying he would rather concentrate on the state’s development. “It is common for the opposition to criticize the government, but I’m busy preparing for the budget, which will be presented on March 5. I am concentrating on my work,” he said.

In Davangere, Yediyurappa said he is committed to increasing internal reservation for the Valmiki community under the ST quota from 3% to 7.5%, apart from considering a separate department for the community to address their issues. Speaking at a Valimik community event, Yediyurappa said Justice Nagamohan Das has been asked to submit his report at the earliest to bring in reservation.

In Mysuru, chief minister Yediyurappa’s son and BJP Yuva Morcha general secretary BY Vijayendra on Sunday said the district will get representation in his father’s cabinet soon, pointing to the six existing vacancies. He said former minister AH Vishwanath will be made a minister as Yediyurappa is known for delivering on his promises. Speaking to reporters, he said his father has expanded his council of ministers, ensuring there were no complaints and he will include more legislators given that there are six more vacancies.

Bengaluru, Feb 13: Karnataka Chief Minister BS Yediyurappa on Thursday said the government had initiated measures to implement the Sarojini Mahishi report as the 12-hour Karnataka bandh call by several pro-Kannada organisations under the banner of Karnataka Sanghatanegala Okkoota began on Thursday.

“Government always stood for Kannada and Kannadigas and initiated measures to implement the Sarojini Mahishi report,” Yediyurappa said. Meanwhile, in Bengaluru, Ola, Uber and auto services were affected even though buses were plying as usual. Security has also been beefed up in Bengaluru after stones were pelted at a Tirupati-Mangaluru bus in Farangipet, though no one was injured.

Bangalore University has postponed all postgraduate (PG) exams scheduled for today. A pro-Kannada activist, Praveen Shetty, was kept under house arrest and police have detained a few people, including those involved in Cauvery protests and other bandh cases.

The organisations are demanding the implementation of a report by former union minister Sarojini Mahishi that recommends a certain percentage of jobs to Kannadigas in public sector undertakings, private companies, and multinational companies. The report was submitted in 1984 but is yet to be implemented.
