Protests held in Mangaluru, Udupi against cow slaughter

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, May 22: There will be complete lockdown in Dakshina Kananda from 7 p.m. on Saturday (May 23) to 7 a.m. on Monday (May 25). 

Announcing this today, Deputy commissioner Sindhu B Rupesh clarified that there would be no restrictions on sale of newspapers, vegetables, fish, meat, milk and medicine.

Other shops, hotels and bars will remain closed. Movement of private vehicles also banned during this period.

Under lockdown period, people are instructed to stay indoors and all non-essential activities are restricted. 

Under coronavirus lockdown, people can step out only for essential activities like medical supplies, grocery shopping, and hospital appointments.

Wedding with permission

If marriages have been scheduled already on Sunday, they will be considered as a special case. However, prior permission is must for scheduled weddings, said the deputy commissioner.

Marriages can be permitted by ensuring social distancing, capping the number of guests at 50 and strict compliance with all other guidelines.

No AC, no consumption of liquor and paan, no invitation to people aged above 65 and below 10 and also pregnant women are some of the guidelines to be followed for holding marriages or events.

Containment zones 

In the corona containment zones that have been sealed no one can step out, only home delivery of essential services are allowed. Only movement of medical vehicles will be allowed and no one will be allowed to perform any other activity. No one will be allowed to step out of their home even for essential services. The govt may take legal action if anyone is seen out of their home.

New Delhi, Jan 30: A terrorist opened fire at people peacefully protesting against the contentious citizenship amendment act (CAA) near the Jamia Millia Islamia University in Delhi this afternoon, causing chaos and panic in the area.

One person has been injured. In a video, the terrorist, wearing a black jacket and a pair of white trousers, can be seen walking on a road, waving a gun as he shouts "who wants Azadi, come I'll shoot you. Then he says, "Yeh lo aazadi (here's your freedom)" and opens fire injuring a student in front of police.

A video of the attack that is being shared widely on social media also showed the assailant also shouting the 'Jai Shri Ram' slogan and warning protesters to chant 'Vande Mataram' if they want to stay in India. The injured student, Shadab, was hit by the bullet in his arm and has been admitted to the Holy Family hospital in Jamia Nagar.

His condition is stated to be stable. The incident took place near the hospital when a protest march was being taken out by students. Students said that the attacker tried to hijack the peaceful protest and threatened the anti-CAA agitators.

The shooting comes in the aftermath of communally charged, hateful and violence provoking rhetoric by several BJP leaders in the run-up to the assembly elections in Delhi.

Junior finance minister Anurag Thakur had on Monday led chants of ‘shoot the traitors’ at a poll rally in north Delhi’s Rithala. The minister prompted "desh ke gaddaron ko..." to which the crowd responded "...goli maaro sa***n ko". The chant translates to "shoot down the traitors who betray the country". Protesters against the CAA and the NRC have often been dubbed anti-national by members of the ruling BJP.

After Thakur’s hate speech, a man carrying a gun was also caught at Delhi's Shaheen Bagh, the venue of mega protests. The man had walked into the protest ground and allegedly brandished the weapon till he was overpowered by the surrounding protesters, eyewitnesses said.
