In Ajjarkad dist hospital, a rare display of Hindu-Musilm bond and a brazen assault by the doctor

Bengaluru, Feb 20: Leaving the organisers of an event to protest against the CAA, NRC and NRP here red-faced, a young woman on Thursday reportedly raised "Pakistan Zindabad" slogan in the presence of AIMIM chief Asaduddin Owaisi, who denounced her action and asserted "we are for India".

The woman, identified as Amulya, allegedly asked people to shout with her "Pakistan Zindabad" after the organisers of the event under the banner of "Save Constitution" invited her to address the gathering soon after Owaisi came on the stage.

Soon Owaisi rushed to snatch the mike from her hands and was joined by others who tried to remove her from the state.

But the woman was adamant and raised the slogan again repeatedly. Later, the police stepped in and removed her from the dais.

Owaisi then addressed the gathering, saying he did not agree with the woman.

"Neither me nor my party has any link with her. We denounce her. The organisers should not have invited her here. If I knew this, I would not have come here. We are for India and we no way support our enemy nation Pakistan. Our entire drive is to save India," the AIMIM MP said.

JD(S) corporator Imran Pasha claimed she was planted by some rival group to disrupt the event.

The woman, he said, was not in the list of speakers and demanded that the police investigate the matter seriously.

Sources say Amulya hails from Chikkamagaluru and her parents have always been in the forefront of taking on government and its policies for well over a decade. 

As per local TV reports, the student was taken to Upparpet police station, but later shifted to an undisclosed destination for more questioning.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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