Shettar seeks probe on Indira Canteens violating quantity specifications

Mangaluru, Mar 10: Four airports which are run by the Airport Authority of India (AAI), including Mangaluru International airport, have been adjudged among the best aerodromes in the world, winning 10 awards in four different categories at the 2019 ASQ awards.

ASQ is a globally established programme that measures passengers’ satisfaction while traveling through an airport. Airports Council International (ACI), which is an independent agency of airport operators, carries out international benchmarking of aerodromes.

“Four AAI airports — Chandigarh, Mangaluru, Trivandrum and Lucknow — have been adjudged the best in the world in recently announced 2019 ASQ awards. These airports won 10 awards in four categories,” Airports Authority of India (AAI) said in a release here on Tuesday.

The survey measures passengers’ satisfaction across 34 key performance indicators that include eight major categories such as access, check-in, security, airport facilities, food and beverage, retail, airport environment and arrival services.

The four categories in which these airports bagged the best airport awards were size and region, environment and ambiance, customer service and infrastructure and facilitation, as per the AAI.

The survey was carried out at across 356 airports across North America, Latin America and the Caribbean, Europe, Africa, the Middle East, and Asia.

The survey results are monitored by airport tariff regulator AERA, NITI Aayog, and civil aviation Ministry, the release added.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

New Delhi, Feb 24: The National Investigation Agency (NIA) is conducting raids at more than 20 locations in Karnataka and Tamil Nadu. The latest raids are being carried out in connection with ISIS conspiracy cases.

More details are currently awaited regarding the cases.

Meanwhile, NIA had on February 15 filed a charge sheet against two Lashkar-e-Toiba (LeT) terrorists before the agency special court, Jammu. The two terrorists are identified as Khalil Ahmad Kayani (34) and Mohammad Nazeem (23), both residents of Haveli Farwad Kahuta district in Pakistan occupied Kashmir (PoK).

The case is related to the arrest of the two accused near Nilkanth Nala, approximately 700 metres inside the Indian side of LoC, in Gulmarg Sector of Baramulla district.
