Three more arrested for attack on Bajrang Dal activist

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Belagavi, Apr 30: Police Sub-Inspector attached to Sadalaga Police Station Anil Kumbar was suspended on Wednesday pending inquiry for negligence and misbehavior in Examba incident, Superintendent of Police Laxman Nimbargi said.

According to him, the PSI was suspended as he misbehaved with Sachin Sawant a Centeral Reserve Police Force (CRPF) Cobra Commando on April 23 at his native village Yakshamba village and arrested him on charges of not wearing mask. On scuffle with the constable the commando was handcuffed and chained at Sadalaga police station.

Sachin Sawant was sent to Hindlaga Jail by the Court and was released on conditional bail on Tuesday.

Newsroom, Feb 7: Prime Minister Narendra Modi’s recent statement that there is no detention camp in India is no more a lie. That doesn’t mean that there are no detention camps in the country, but the name of the camps have changed. 

In December, at a mega rally at Ramlila Maidan, meant to launch the BJP's campaign for the assembly elections in Delhi, Mr Modi had stated: “The rumour of detention centres being spread by the Congress and urban Naxals is totally false. This is being done with a bad intention to destroy the country, it’s filled with evil motives; this is a lie, lie, lie.” He had further claimed: “Neither are any of the country’s Muslims being sent to detention centres nor is there any detention centre in India”

In reality there are at least six detention camps in jails in Assam to house foreigners found staying in India illegally. A month prior to PM’s statement, Union minister of the state for home affairs Nityanand Rai had revealed that the six camps in Assam housed 1,043 foreigners — 1,025 Bangladeshis and 18 Myanmarese. Apart from these, at least ten new detention centres are coming up.

Outside Assam too, the Maharashtra government, under the then chief minister Devendra Fadnavis, had identified land for the state’s first detention centre for illegal immigrants.

Besides, in a case relating to illegal immigrants in Karnataka High Court in November this year, the Centre had told the court that it had written to all state governments in 2014 and sent a follow-up letter in 2018 to have detention centres to house foreign nationals illegally staying in India.

Karnataka’s first detention centre, apparently meant to lodge illegal immigrants and migrants overstaying in the country, is already open in Sondekoppa village on the outskirts of Bengaluru. The facility with several rooms, a kitchen and toilets has been kept ready on the directions of the government. 

Meanwhile, Union Minister of state for home Nityanand Rai has told the Lok Sabha that the name "detention centre" has now been changed to "holding centre".
