Second hovercraft glides into Mangalore

Mangalore, Jan 15: In one of the biggest seizure of gold in the new decade, Directorate of Revenue Intelligence (DRI) sleuths here have seized five kg of gold valued at Rs two Crore from the Air Cargo Complex at International Airport here recently.

Acting on a tip-off the officers of Directorate of Revenue Intelligence (DRI) Bangalore and Mangalore in a co-ordinated effort unraveled a unique modus of smuggling of gold through Air Cargo Complex, at old airport, Bajpe Mangalore two days back, According to release issued here on Tuesday evening.

The smuggled gold was concealed in five metal sprockets which were imported by M/s Swaroop Mineral Pvt Ltd of Udupi in the name of “mining conveyor drive chain”.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, Jul 17: Bruhat Bengaluru Mahanagara Palike (BBMP) Mayor, M Goutham Kumar on Friday called for an extension of lockdown in the city for one more week due to rise in the COVID-19 cases.

"It will be better if we get more time to tackle COVID-19 cases, we wish for the extension of lockdown for one more week. We have given the proposal to the government," said M Goutham Kumar, BBMP Mayor.

"After the number of cases increased in Bengaluru, BBMP started antigen test in containment and hotspot zones of Bengaluru to tackle the cases which have crossed 2,000 mark," he added.

Along with Mayor, BBMP Commissioner Anil Kumar has also proposed the state government to extend lockdown in Bengaluru for one more week.

"The number of cases in Bengaluru increasing in Bengaluru rapidly. BBMP has inaugurated more than 200 vehicles in Bengaluru for the use of the antigen test," said Anil Kumar, Commissioner BBMP.

According to the Union Health Ministry, there are 51,422 COVID-19 cases in the state.
