Three NRI students killed in Sharjah car crash

Feb 25: Two Customs Preventive officers allegedly involved in gold smuggling cases in Kerala were removed from service, a top official said in Kochi on Monday.

Sumit Kumar, Commissioner of Customs (Preventive), Kochi, said that he took action against Radhakrishnan B, Superintendent of Customs, and Rahul, Inspector of Customs, who were allegedly involved in gold smuggling cases in the state.

Radhakrishnan was involved in attempted smuggling of gold weighing 24998.61 grams having a market value of over Rs 8 crore through Thiruvananthapuram international airport on May 13, 2019, Kumar said.

Rahul was involved in attempted smuggling of gold weighing 11,035.54 grams valued at over Rs 4 crore through international airport on August 19, 2019, the Customs Commissioner added.

Radhakrishnan is currently lodged in Central prison, Thiruvananthapuram after the Central Economic Intelligence Bureau under the Union Finance Ministry issued detention order under COFEPOSA (Conservation of Foreign Exchange and Prevention of Smuggling Activities Act, 1974).

Rahul, against whom detention order under COFEPOSA was issued, is absconding.

"Two Customs officers of the Customs Preventive Commissionerate, Kochi, who were involved in gold smuggling cases were removed from service by Sumit Kumar, Commissioner of Customs (Preventive), Cochin," an official release said.

Kumar said that both the cases were booked and investigated by the Directorate of Revenue Intelligence and while show cause notice under Customs Act 1962 has been issued against Radhakrishnan, investigation is under progress in the other case.

"Both the officers were removed from service, after due process of law under Rule 19 of the Central Civil Services (Classification, Control and Appeal) Rules, 1965," the release said.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Mar 23: Karnataka government today decided to go for complete lockdown. This includes the closure of all non essential government offices, suspension of all public transport services and banning of mass prayers in places of worships across the state.

Chief Minister BS Yediyurappa had expressed the need for a complete lockdown like the Janta Curfew on Sunday. Going by this, there will be no government transport services at least till March 31 and as many as 19,000 government buses will be off the road.

The government also decided to cancel the famous Karaga festival. The CM said that all celebrations and functions will be called off along with mass prayers in mosques and churches.

The CM said that they have decided to procure 1,000 ventilators and 10 lakh face masks in addition to other health equipments.

Private hospitals have come forward to spare their doctors and nursing staff to attend to Covid-19 patients in government hospitals, the CM said.

Yediyurappa also said that he has directed the health department to paste notification on the houses of residents who are infected with coronavirus. This is being done after people with indelible seals and home quarantined are reported to be roaming freely. The notifications will help neighbours to keep an eye on them.

The CM said the government-run Indira Canteen will serve free food to the poor until the lockdown continues. He also said that action will be initiated against non essential shops that are open despite a directive to shut down.
