Political uncertainty in State contributed to the woes of teachers: BJP MLC

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Dubai, Jul 5: Three Indians, who were repatriated on a chartered flight from the UAE on Friday, have been held in the state of Rajasthan after officials seized gold worth Dh2.2million from them, the government announced on Saturday.

They are likely to be placed under arrest along with 11 others, who were repatriated from Saudi Arabia, from whom gold worth Dh5.5million was seized, a statement from the government tweeted by Press Information Bureau in Rajasthan said.

The gold bars were hidden in emergency lamps, photos attached to the tweets showed.

The 14 passengers had arrived at the Jaipur International Airport by two chartered flights.

They were intercepted by the Customs team at the airport and 31.9kg of gold valued at Rs156,759,820 (Dh7.7million) concealed in the baggage was recovered from these passengers.

Three passengers arrived from Ras Al Khaimah by Spice Jet Flight SG9055 and 12 gold bars/bricks weighing 9.3kg valued at Rs.45,761,100 (Dh2.2million) were recovered from them, the statement said.

The Indian Consulate in Dubai confirmed to Gulf News that the flight was chartered by a private company for repatriating its employees.

It is suspected that the passengers were used as carriers to smuggle gold.

The other 11 accused had arrived from Riyadh and 22.65kg of gold bars, predominantly with Suisse markings, valued at Rs110,998,720 (Dh5.5million) were recovered from them.

“The said recovered gold bars have been seized under Section 110 of the Customs Act, 1962. The said passengers are being interrogated and are likely to be placed under arrest in terms of section 104 of the Customs Act, 1962,” the statement added.

Indian media had earlier reported similar cases in which stranded Indians were apparently lured to be carriers for smuggling gold on repatriation flights from various countries.

A spike in gold smuggling attempts using Indians getting repatriated after losing jobs was also reported from the Indian state of Kerala.
