Mangaluru: Budding businessman commits suicide

Mangaluru, Apr 20: The Dakshina Kannada district administration had declared certain areas in the district as containment zones after COVID-19 positive cases were detected from there.

A seal down has been declared in these zones, completely banning all movement of the people including leaving their houses.

In Ajjavara, Sullia taluk a one-kilometre containment zone has been set up on April 19.

The zone stretches from Ankotimar Road and includes Forest agriculture land and the residences of Savera and Achar.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

New Delhi, Mar 3: Bharatiya Janata Party leader Kapil Mishra, who instigated violence in northeast Delhi by provoking mobs, has now been provided with 24x7 security. After he claimed threat to his life, he has been provided with “Y” category security — which entitles him to six security personnel round-the-clock to guard him in and outside the city.

He had fought the 2020 Delhi Assembly elections by giving inflammatory remarks around the anti-Citizenship Amendment Act in Shaheen Bagh, and lost to Aam Aadmi Party candidate. But he continued to issue provocative remarks.

While there is clear evidence of his scandalous statements just a day before the violence was unleashed on Muslims in Delhi last week where around 50 people were killed, no action has been taken against him so far. Instead, he is being treated as a hero in his party.

As per sources, Mishra complained that he got life threats over the past week in wake of the violence and based on his request, the Delhi Police has provided the security cover.

Mishra had taken to social media platform Twitter and alleged that he was receiving threats via WhatsApp, Twitter and Facebook, from Indian and foreign accounts.

“I am constantly being threatened with murder on the phone, on WhatsApp, on email. Hundreds of threats are being given continuously from the country and abroad. I don’t fear this hate campaign against me,” he had said on Twitter on March 1.

Mishra had on February 23 made an incendiary speech, following which North-East Delhi witnessed anti-Muslim violence.

The Supreme Court of India on Monday said it will on Wednesday (March 4) hear a plea that sought immediate FIRs against Kapil Mishra, Union Minister of State for Finance Anurag Thakur and other leaders for their recent hate speech, which allegedly triggered the violence in Delhi. The plea was filed by Delhi violence survivors.

The apex court bench, comprising Chief Justice SA Bobde, listed the matter for hearing after senior advocate Colin Gonsalves, who is appearing on behalf of the survivors told the SC that the Delhi High Court had last week adjourned the matter for six weeks even as “people are dying every day”.
