'Passport Seva Kendras' in each 543 parliamentary constituencies: Union minister

Bengaluru, Feb 29: Gangster Ravi Poojary, who was arrested from Senegal earlier this week, and is being interrogated by the Cental Crime Branch (CCB) police, wants to evade the Mumbai police for any kind of inquiry. Claiming that there is a serious threat to his life, he is believed to have told his investigators that he should not be sent there. Poojary is being grilled by the CCB for his alleged involvement in numerous cases.

“He is aware that he will be given to the custody of Mumbai police as he had committed several crimes before fleeing India and also made hundreds of extortion calls to the well-heeled there. Hence, he has started requesting us not to send him to Mumbai. He claimed that he has many rivals there and they may go to any extent to get him killed,” a source said. Poojary was once an associate of dreaded underworld don Dawood Ibrahim.

Poojary has little option but to face Mumbai cops

Poojary had left Dawood’s gang and had joined Chhota Rajan, who split from D-Company and established his own network. There were also attempts by Dawood’s men to assassinate Rajan on a few occasions. During his days in Mumbai, Poojary was also reportedly facing threats from Dawood and other gangsters. “Since Poojary had jumped bail in the murder case of a gangster in Mumbai and f l e d the country, he has no option but to face trial again. Besides, he has made over a hundred extortion calls to businessmen and celebrities in Mumbai in the last two decades.

It’s inevitable for him to face inquiry by the Mumbai police,” an official said. “Now that he knows his options are limited, he is requesting us not to send him to Mumbai under any circumstance, claiming that he faces a serious threat to his life by Dawood’s aides and others. However, when we are done with questioning him, and if Mumbai police approach the court, it will decide whether to give him to their custody or not,” the official added. Poojary, who was brought to India on February 24, has been remanded to police custody till March 7. The police are likely to seek extension of his custody as he is facing close to 100 cases in Karnataka.

Cases filed in 4 states the gangster, originally from Malpe in Dakshina Kannada, has cases against him in Kerala, Maharashtra, and Gujarat. At least 46 cases are registered in Bengaluru alone.

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
