Godhra tragedy: Guj HC reduces death sentence of 11 to life term

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

More than 500 flights are expected to be operated in the fourth phase of Vande Bharat Mission, the “paid evacuation” mission of the government of India during covid-19 crisis.

This includes both Air India and private carriers who are ramping up their operations in a big way. 

Air India will be operating 170 flights till 15th of July to and from 17 countries, including Australia, Bahrain, Bangladesh, Canada, Germany, Japan, Kuwait, Malaysia, Oman, Saudi Arabia, Qatar and Philippines.

Private airlines such as IndiGo and GoAir will have significant participation in the fourth phase of Vande Bharat Mission. 

The Civil Aviation Ministry said that among others, Indigo will operate 238 flights from Qatar and 219 flights from Kuwait. GoAir will operate 41 flights from Kuwait. Phase Four will particularly focus on countries where there still are a large number of Indians who have registered to return.

Meanwhile, a record five lakh stranded Indians have returned safely to India under the Mission till now. The operations commenced on 7th May and in less than two months, nearly five lakh four thousand stranded Indians from 137 countries have returned to their homes.

Bengaluru, Feb 29: Dreaded underworld don Ravi Poojary's lawyer Dilraj has allegedly been kept out of hearing distance and as a mute spectator during interrogation by the police.

"The lawyer is a mute spectator out of hearing distance from the interrogation. He is not privy to what police ask Pujari," a source told media.

As directed by the court and requested by Poojary, Dilraj is allowed to be present near the interrogation for him to consult on legal issues, but the cops have made sure that he does not hear anything for fear of leaking information.

The court has also ordered the interrogation to be video graphed, which the police are carrying out.

Police sources said that Ravi Poojary is relaxed and cool during the multi-lingual interrogation.

"He is cool, giving frank replies. Poojary is exhibiting confidence in whatever he is telling. Maybe confidently lying, police are not new to him," said the source.

According to source, the gangster knows how to handle police, with sufficient knowledge to reveal how much he wants to, when to stop, when to talk, when to mislead and plant false information.

"Poojary is being interrogated in his mother tongue Kannada, Hindi and English. He is fluent in English," the source said.

However, the source denied speculation gaining currency that Poojary requested police not to send him to Mumbai fearing of being eliminated by the henchmen of dreaded underworld dons Dawood Ibrahim and Chota Rajan.

"Nothing of that sort happened. It doesn't work like that. He has been captured after 25 years, and he is not a king to choose. Wherever the law takes him, he will go there," said the source.

Rajan is serving a life sentence inside a high security cell in Delhi's Tihar jail.

Currently, the probe is focused on Tilknagar Shabnam Developers double murder shootout case. Police are discovering information, verifying it with respect to evidence and building the case.

Taking regular breaks, police are interrogating Poojary from morning till evening.

Of the over 200 cases against Poojary in the southern state, 39 are in Bengaluru, 36 at Mangaluru, 11 in Udupi on the state's west coast and one each at Mysuru, Hubballi-Dharwad, Kolar and Shivamogga in Malnad.

The other cases are in Mumbai (49) and in Gujarat (75) pertaining to extortion, kidnapping, ransom demand and murder threats.

Poojary also extorted huge amounts from popular Bollywood stars and realtors. He was also involved in an attempt to murder case, aimed at killing a prominent lawyer of Mumbai.

A four-member Karnataka police team led by Pandey brought the 52-year-old underworld don to Bengaluru from Dakar in Senegal via Paris in an Air France scheduled flight during the wee hours and kept him at an interrogation centre in the city's south-east suburb.
