Mangaluru: Students protest after finding dead rats, cats in college well

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Feb 22: Student activist Amulya Leona, who was arrested on sedition charge after she raised ‘Pakistan Zindabad’ slogans during an anti-CAA event at Bengaluru’s Freedom Park on Thursday evening, has now criticised the organisers of the event for snatching away microphone from her hand.

The event was organised by ‘Hindu Muslim Sikh Isaai Federation’. Soon after she started pro-Pak slogans All India Majlis-e-Ittehadul Muslimeen (AIMIM) chief Asaduddin Owaisi rushed and tried to snatch mic from her hand. When she continued to speak, her microphone was deactivated.

According to police, the 19-year-old BA journalism student blamed her predicament on the organisers of the protest for not allowing her to complete what she wanted to say on stage.

"Maybe she had intended to say what she had recently posted on her Facebook page where she has said ‘Zindabad’ to all the countries, including India and Pakistan. But it went awry. She was not answering any of our questions, but kept saying she had not done anything wrong," a senior police officer was quoted as saying by a news paper.

The police have booked Leona for sedition and promoting enmity between groups. After her arrest, she was thoroughly questioned by the police for over two hours. After recording her statement, the police produced her before a magistrate in the wee hours of Friday. When she was taken to the judge’s residence, located at the National Games Village in Koramangala, Leona pointed towards the TV cameras and flashed a victory sign.

As the police did not seek her custody, the judge remanded her to judicial custody and she was subsequently taken to Bengaluru Central Prison at Parappana Agrahara. Her advocate is expected to file a bail application in the court on Monday.

When the police took her into custody at Freedom Park and quizzed her, she reportedly did not answer any of their questions but kept insisting that she had not done anything anti-national to be charged with sedition.

"It was the organisers’ mistake to snatch the mike from me before I completed what I had to say. Because of them, I have been arrested today. If they had given me a chance to complete what I had to say, nothing like this would have happened. Now, there is no point in telling you what I intended to speak there. But I can say that there was nothing anti-national in what I did. You can initiate action against me and my advocate will fight the case," a source, citing Leona, said.

The police recorded whatever she said as her voluntary statement and submitted it to the magistrate. "We tried to find out why she did what she did and whether there was anyone else behind her making such a statement. But it appears she had done it on her own," the police official said.
