Bengaluru, Jun 23: Karnataka Congress leader and Kanakapura MLA DK Shivakumar said on Monday that in the wake of coronavirus pandemic, people of his assembly constituency have taken a unanimous decision of remaining under voluntary lockdown until July 1.

The decision was taken after he headed a meeting at Kanakapura on Sunday, at the office of Kanakapura Municipality.

"Let us consider the situation after July 1, hold a similar meeting, and take the next decision. It has nothing to do with the state government's mandate. It came to the conclusion that this was a decision that we all voluntarily took," said DK Shivakumar.

DK Shivakumar informed that the merchants have agreed to sell groceries, fruits, vegetables, fennel, meat and other food items from 7 a.m. to 11 p.m. only. District authorities, DCs, SPs and hospital representatives have decided the timings of clinics and drug stores.

He further said, "In this self-motivated lockdown, unnecessary driving should be avoided. The social gap must be maintained. No one should be oppressed by anyone."

Member of Parliament DK Suresh, Ravi - Ramanagara District Collector Archana, SP Anoop Shetty, and Kanakapura Planning Authority Chairman Jagannath were also present in the meeting.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, Mar 10:  Country’s economic condition is not permanent. All young entrepreneurs can be forward looking persons, because all bad times are followed by good times. In fact, it is good time to start your own industry, said Nitte Deemed to be University Chancellor Dr. N Vinaya Hegde. 

Addressing the gathering after inaugurating a three-day entrepreneurship symposium organized by Mangalore University and Department of M. Com and MBA, University Evening College at University College Mangalore here on Monday, he said that entrepreneurship is something you enjoy. You should belief that there is something in you to achieve your area of choice. You should get pleasure out of it. 

Ex-MLC Capt. Ganesh Karnik believed that our population is definitely a resource, but symposiums are needed to convert ideas to implementation. Coastal Karnataka is best example for successful entrepreneurship in health, education sector, he added. 

Presiding over the function, Mangalore University Vice Chancellor Prof. P Subrahmanya Yadapadithaya said that students should be universally compassionate before being an entrepreneur. There will be challenges, failures in entrepreneurship. One should trust himself, and should have courage and confidence to be innovative. One should have aspiration and passion for excellence, he added.

Young scientist, international awardee Swasthik Padma was felicitated on the occasion. Evening college Principal Dr. Ramakrishna B M, Coordinator  Dr. Yathish Kumar were present among others. Kavya P Hegde mastered the ceremony, Venkatesh Nayak presented vote of thanks.
