Mangaluru: St Aloysius College gets prestigious UGC Research Grant

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

In a humanitarian gesture to help fellow citizens in distress, the first in the series of chartered 
flights arranged by Thumbay Group, UAE and the Bearys Cultural Forum (BCF) Trust, 
Mangalore to repatriate stranded Kannadigas in the UAE took off from Ras Al Khaimah 
International Airport in the wee hours of 21st July 2020. The flight was fully occupied, with 186 passengers, all of them desperate to fly back to India for various reasons.

The initiative was conceived and implemented under the leadership of Dr. Thumbay Moideen - Founder President of Thumbay Group & Founder Patron of BCF and Dr. B K Yusuf, the 
President of BCF. The flight was organized on a purely charitable basis, with all necessary 
steps and precautions in place to ensure the safety and comfort of passengers. Thumbay Group assigned its fleet of buses to transport the passengers free of charge from their residences in Dubai, Sharjah and Ajman to the airport. The organizers also provided free meals and refreshments to the passengers, in addition to PPE kits and face-shields distributed free of 
charges.

The passengers on the first flight included many elderly individuals, people with serious 
illnesses like heart-related health issues and diabetes, pregnant ladies and little children as well as people who had lost their jobs and those with expired visas. Dr. B K Yusuf – BCF President, Dr. Kaup Mohammed - BCF General Secretary, other office bearers of BCF, as well as Thumbay Group’s representatives Mr. Farhad C – Director of the Hospitality Division of 
Thumbay Group and Engr. Farwaz P. C. – COO of the Construction Division were present at 
the airport to see off the first group of passengers.

Commenting on the initiative, Dr. Thumbay Moideen said, “This joint initiative of Thumbay 
Group and BCF is to support our fellow Kannadigas desperate to fly back home. We are happy that we have been able to reach out to many of them, to help them fly home to their families. We thank the Governments of the UAE and India, and the Indian Consulate, Dubai, for their support in making this happen. In the coming days, many more stranded Kannadigas would be repatriated under this joint initiative.”
Dr. B K Yusuf thanked Dr. Thumbay Moideen and the office-bearers and members of BCF for 
their efforts to make the initiative a success.

“We are proud that this initiative has brought relief to many Kannadigas and their families today. BCF is grateful to Thumbay Group for its support and partnership for all our humanitarian programs for the support of the needy.”

Dr. Kaup Mohammed said that it was a matter of pride that the much-awaited Thumbay-BCF 
repatriation flight had been carried out successfully. “Measures have been taken to ensure the safety of the flight and its passengers throughout the journey,” he said. He also thanked all the social organizations including Bhatkal Jamath, BCCI, BWF, KCF, DKSC, Kodagu Kannadigas, 
Kannadiga Help Line, Dubai Konkans and KSS, for their support. He specially thanked Mr. 
Syed Hassan Razeen, the owner of ARISTOCRAT Travels for his support in the ticketing, 
boarding and related processes. On behalf of Milano Optics Group and Maxcare, free gift 
hampers were distributed to selected passengers.

T. Ifthikhar, Mr. S. M. R Rashid - President of BCCI central committee and many others. The passengers were transferred to the hotels where they had registered for the mandatory quarantine.
