LPG tanker topples near Nelyadi; traffic diverted after gas leakage

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 5: An earthquake of magnitude 4.0 on the Richter Scale jolted Karnataka on Friday morning while another with a magnitude of 4.7 was felt in Jharkhand.

The tremors were felt in Hampi (Karnataka) and Jamshedpur (Jharkhand), according to the National Center for Seismology (NCS).

According to NCS, the aftershocks were felt at 6:55 am in both the places today.

Mangaluru, June 28: In his apparent bid to win the hearts of the people of Tulu Nadu while leaving this coastal city, Dr P S Harsha, the outgoing Mangaluru city police commissioner, today took to social media and thanked the people. The language he chose for his prolonged Facebook post and one paragraph tweet was Tulu.

“Loveable people of Kudla! I have received the transfer order after serving as the Commissioner of Police of Mangaluru City for 11 months. (During this period) I worked with utmost honesty and pro-people approach with the complete cooperation of my department. I wholeheartedly thank all those who supported me,” tweeted Dr Harsha, who is now posted in Bengaluru as the Deputy Inspector General and Commissioner of Information and Public Relations.

In his Facebook post, Dr Harsha claimed that thanks to his initiative “My Beat My Pride”, the policing in the coastal city has strengthened. 

“My only intention was to put an end to rowdyism and illegal activities. I had given priority to curb the drug mafia. ‘My Beat My Pride’ became a successful initiative thanks to public support,” he said. 

The IPS officer went on to claim that with the with the co-operation of the senior officers, the police department managed to efficiently handle situations during anti-CAA and pro-CAA agitations in the city, detection of explosives at Mangaluru International Airport and also during the covid-19 pandemic. 

However, he did not mention about the death of two people in random police firing following a baton charge during anti-CAA protests in the city on December 19.
