‘Entire world should embrace Islam’: Out-of-context clip of Om Puri goes viral

Mangaluru, Feb 13: Jnandev Kamath, former President of erstwhile Mangalore Stock Exchange Limited died late last night in a private hospital in the city.

He was 65 and is survived by his wife and two daughters.

Jnandev Kamath was an alumnus of SDM College of Law and Business Management. 

He was one the founding members of Mangalore Stock Exchange Limited. He was an avid sportsman, an accomplished cricketer, a champion rallyist and golf coach. 

He often played for Pentlandpet Sports Association (PPSA) in his younger days.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

A 53-year-old Indian worker in the UAE has missed a special repatriation flight after he dozed off at the Dubai International Airport, a media report said.

P Shajahan, who worked as a storekeeper in Abu Dhabi, was supposed to fly to Thiruvananthapuram on the Emirates jumbo jet chartered by the Kerala Muslim Cultural Centre (KMCC) Dubai, Gulf News reported.

It was the first-ever jumbo jet chartered for repatriation.

Shajahan, who had paid 1,100 dirham (USD 300) for the ticket, said that he did not sleep on the previous night as he kept on waiting for the confirmation of his ticket for the jumbo jet flying 427 stranded Indians to Kerala, it said.

He reached the airport early in the morning and after finishing the check-in procedures and rapid test, he reached the waiting area of the boarding gate at Terminal 3 around 2 PM local time, the report said.

“I sat away from most of the others. But I fell asleep after 4.30 PM,” he said.

S Nizamudeen Kollam, who coordinated the charter flight, said that the airline officials could not trace Shajahan when the flight was to take off.

“He woke up and called us after the flight left. It is sad that he missed the flight, which was the first-ever jumbo jet chartered for repatriation. We are now trying to send him on another Emirates flight that we are chartering on Saturday,” Kollam said.

Since Shajahan did not have any money, Jasimkhan Kallambalam, organising secretary of KMCC Thiruvananthapuram, went to the airport to meet him on Friday.

“Since his visa was cancelled, he could not come out of the airport. He had only eaten the snacks in the kit KMCC had given. We managed to give him some cash for buying food through KMCC volunteer Alamsha Latheef,” Kallambalam said.

In March, another Indian expat had fallen asleep in the same terminal and missed the last flight home before flights were suspended due to the COVID-19 pandemic.

He was stranded here for over 50 days before getting repatriated.
