I love Saudi King Salman; He might not be there for two weeks without us: Donald Trump

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jan 13: RSS leader Kalladka Prabhakar Bhat on Monday held a protest march at Ramnagar district’s 
Kapalabetta under the aegis of Hindu Jagran Vedike’s ‘Kanakapura Chalo’ campaign against the construction of the world’s largest Jesus statue there.

Hundreds of protesters of the Vedike staged a protest march in the city starting from the Kanakapura Ayyappaswamy temple.

“We are not here to disturb the peace. We have met each other at the wedding of Sriramulu’s daughter. So you know who I am, DK Shivakumar. How long will you continue with these lies? Is the intention behind the statue of Jesus to solidify your vote bank? Build the statue in America or England, we will not allow it here,” said the RSS leader as the keynote speaker at the rally.

Bengaluru, Jun 15: Karnataka Chief Minister B S Yediyurappa on Monday laid the foundation stone for the construction of a Rs 220 crore airport project in his political bastion of Shivamogga, as he expressed confidence that it will give a boost to tourism, industries and economic activities in the region.

"The long cherished dream of people of Shivamogga about having an airport is finally becoming a reality.

The project that was planned when I was Deputy Chief Minister and Chief Minister in the past was shelved due to contractor issues and lack of interest by the governments that came later," Yediyurappa said.

Speaking at the foundation laying event for the airport, which he attended virtually via video conference, he said, now the government is once again taking up the project through infrastructure development and PWD departments.

The project to construct the well-equipped airport at Sogane in Shivamogga taluk at the cost of Rs 220 crore in about 662.38 acre land area has been initiated, he said, adding that the project will be taken up in two phases.

He expressed hope that it will be completed in a year's time.

The first phase consists of runway, taxiway, apron, approach road, peripheral road and compound wall construction, while the second phase consists of terminal building, ATC tower, fire station building, among others, a release said.

Noting that under the Udan scheme the project has been envisaged to provide affordable air travel to people, the Chief Minister expressed confidence about tourism, industries and economic activities in the region getting a boost, with the small airport coming up at Shivamogga.

He also directed officials to complete the airport work on time without compromising on the quality.

Highlighting various developmental works that is being implemented in Shivamogga, the district which is regarded as his political turf, Yediyurappa said, with the cooperation of the central government various railway projects have also been taken up in the district including Shivamogga- Shikaripura rail route.

Shikaripura is the constituency represented by the Chief Minister, while his son B Y Raghavendra represents Shimoga constituency in Lok Sabha.

Yediyurappa, who also inaugurated the divisional office of National Highway authority in the district, said a bridge project across river Sharavati at Singndur in Sagara taluk will be taken up.

Conceding that developmental work has taken a backseat due to the COVID-19 situation, the Chief Minister said the challenge is to overcome it and achieve development.
