Vatican rejects second appeal of Kerala nun against her expulsion from congregation

Bengaluru, Feb 14: Bengaluru Police on Friday said that it has busted a gang engaged in e-commerce fraud over the online marketplace who were involved in 200 of the 316 cheating cases registered last year.

"We registered 316 cases for cheating through online marketplaces last year. We have busted a gang operating from Rajasthan's Bharatpur and arrested 5 people. They are responsible for 200 out of 316 cases. We are questioning the accused," Bhaskar Rao, Commissioner of Police, Bengaluru told reporters here.

Explaining their modus operandi, the Police Commissioner said, "There were fictitious buyers and sellers on the online marketplace. These people used to call up prospective buyers and sellers. The products that were shown were two-wheelers, four-wheelers, electronic items and furniture."

"People used to send their money to these fraudsters using their QR code. The fraudsters were operating from Bharatpur in Rajasthan. A police team of 15 was sent to the place from where they were operating. Rajasthan police gave us full cooperation and we were able to arrest five persons," he added.

Rao said that these fraudsters had an idea about the loopholes in the e-commerce sector and exploited them.
"Some of those arrested were employed in the e-commerce and banking business and they had an idea about the loopholes in this sector," he said.

"We warn the citizens to ensure that they verify the antecedents of the buyers and sellers in this sector before spending money on these platforms," he added.

Bengaluru, May 20: 63 more COVID-19 cases have been reported from Karnataka, taking the total number of coronavirus cases in the state to 1,458 on Wednesday, said the state Health Department.

The total number of cases includes, 864 active cases and 41 deaths (one due to non-COVID cause), it added.

Total 10 people have been discharged today while 553 persons have been discharged so far.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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