Karnataka launches new scholarship scheme for OBC students

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, May 21: The Supreme Court has awarded Rs 7.64 crore compensation to the next of kin of a man who was killed in a crash-landing of Air India Express Flight 812 from Dubai in Mangalore on May 22, 2010. The accident killed 158 out of 166 passengers on board.

The family of the 45-year-old Mahendra Kodkany, which include his wife, daughter and son, were earlier granted Rs 7.35 crore as compensation by National Consumer Disputes Redressal Commission (NCDRC). This compensation will now get enhanced after adding 9 per cent interest per annum (on the amount yet to be paid), to be paid by Air India.

Kodkany was the regional director for the Middle East for a UAE-based company. The aircraft overshot the runway and went down a hillside and burst into flames.

A bench comprising Justices D.Y. Chandrachud and Ajay Rastogi said: "The total amount payable on account of the aforesaid heads works out to Rs 7,64,29,437. Interest at the rate of nine per cent per annum shall be paid on the same basis as has been awarded by the NCDRC. The balance, if any, that remains due and payable to the complainants, after giving due credit for the amount which has already been paid, shall be paid within a period of two months."

The apex court noted that in a claim for compensation arising out of the death of an employee, the income has to be assessed on the basis of the entitlement of the employee. The top court said: "We are unable to accept the reasons which weighed with the NCDRC in making a deduction of AED (UAE currency) 30,000 from the total CTC. Similarly, and for the same reason, we are unable to accept the submission of Air India that the transport allowance should be excluded. The bifurcation of the salary into diverse heads may be made by the employer for a variety of reasons."

The top court observed that the deceased was evidently, a confirmed employee of his employer. "We have come to the conclusion that thirty per cent should be allowed on account of future prospects", added the court.

The top court noted that if the amount which has been paid by Air India is in excess of the payable under the present judgement, "we direct under Article 142 of the Constitution (discretionary powers) that the excess shall not be recoverable from the claimants," said the court.
