Unidentified men hurl acid like chemical on AAP leader Soni Sori

Bengaluru, Jul 24: The Bruhat Bengaluru Mahanagara Palike (BBMP) commissioner on Thursday issued a public apology after "local staff" sealed the doors of two apartments with metal sheets in a building where a positive case of COVID-19 was reported in Dommalur.

Earlier on Thursday, BBMP sealed doors of two flats near Dommalur, in a building wherein a COVID-19 case was reported. A woman with two children, along with an elderly couple stayed in those flats. After the woman tweeted about the incident, BBMP officials removed steel sheets from doors.

Taking the matter into consideration, BBMP Commissioner N Manjunatha Prasad, took to Twitter to express an apology for "over-enthusiasm" of his officials.

He tweeted, "We are committed to address any issues that result in stigma. Apologies for the over enthusiasm of the local staff."

He also said the BBMP is committed to treating all citizens with dignity. "I have ensured removing of these barricades immediately. We are committed to treat all persons with dignity.

The purpose of containment is to protect the infected and to ensure uninfected are safe," he tweeted.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, Apr 25: Bajrang Dal's former Karantaka satate convenor Mahendra Kumar, who dedicated last decade of his life to expose the misdeeds and lies of Sangh Parivar, passed away today due to cardiac arrest here. He was 47 years old.

Kumar was undergoing treatment at Ramaiah hospital Bengaluru where he breathed his last today (April 25) morning. His final rites will be held in his hometown, sources said.

Kumar, who hailed from Koppa in Chikkamagaluru was a resident of Bengaluru.

He had reportedly involved in the 2008 attacks on Christians' places of worship in Mangaluru and Chikkamagaluru and had faced arrest for that. 

However, he quit Bajrang Dal same year and the apologized to Christians. He joined Janata Dal (Secular) in 2011.

After quitting Bajrang Dal and adopting left ideology, he openly attacked the ideology of right-wing outfits. 

He founded Jana Dhwani movement as a voice for the oppressed classes of the state. He used social media to attack the "manuvaad" for past one decade.
