Kerala CM hails Army's plan to induct women in military police

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jan 12: Protesters plan to intensify their anti-Citizenship (Amendment) Act movement from sit-down satyagrahas and rallies to street and door-to-door campaigns in different parts of the city.

The street campaigns began on January 1 with 20-30 volunteers of Hum Bharat Ke Log, reaching out to people in Koramangala and Whitefield and explaining the CAA, National Population Register (NPR), National Register of Citizens (NRC) and related issues. They have organised four campaigns.

According to Zia Nomani, member of Hum Bharat Ke Log, the campaign will intensify soon. “Over 200-400 volunteers will organise nukkad sabhas and other activities around JP Nagar and Banashankari,” Nomani said.

She added that though protests began as a medium for people to vent their concerns, more needs to be done.

“We have realised that many people have begun working on their personal documents and want to help them understand what CAA is all about,” Nomani said.

Volunteers will talk to people at street junctions, discuss issues and run signature campaigns. They say: “Our movement is focussed on reaching out to people. Pro-CAA workers too started a door-to-door campaign last week.”

Avani Chokshi, an advocate who participated in a campaign, said though people had a cursory idea about these issues, they didn’t know the details. “It through such campaigns that we can reach more people. It’s important to talk to people who haven’t made up their mind about the issues or are even pro-CAA,” said Avani, adding, “It hard to combat hatred in a short span of time. The movement needs to be sustained.”

Activist Geeta Menon, who has been at the forefront of the street campaign, says they were heckled at some places.

Mumbai, Jan 19: After Kerala and Punjab, the Maha Vikas Agadi (MVA) government is also mulling over a resolution against the Citizenship (Amendment) Act, 2019 in Maharashtra Assembly.

Speaking to news agency, Congress spokesperson Raju Waghmare said: "Our senior party leader Balasaheb Thorat has also shared his stand on the CAA. Even Chief Minister Uddhav Thackeray has said that we are against the CAA. As far as the resolution against CAA is concerned, our senior leaders of MVA will sit together and decide."

If this happens, then Maharashtra will be the third state to pass a resolution against CAA, which grants citizenship to non-Muslim refugees from Pakistan, Afghanistan, and Bangladesh, who came to India on or before December 31, 2014.

Emphasising that CAA is 'unconstitutional,' senior lawyer and Congress leader Kapil Sibal has said that every state Assembly has the constitutional right to pass a resolution and seek CAA's withdrawal.

He added that it would be problematic to oppose the CAA if the law is declared to be 'constitutional' by the Supreme Court.

"I believe the CAA is unconstitutional. Every State Assembly has the constitutional right to pass a resolution and seek its withdrawal. When and if the law is declared to be constitutional by the Supreme Court then it will be problematic to oppose it. The fight must go on!" Sibal tweeted.

Earlier speaking at the Kerala Literature Festival on Saturday, the Congress leader had said that constitutionally no state can say that it will not implement the amended Citizenship Act, as doing so will be "unconstitutional".

Kerala government has also approached the Supreme Court against the CAA following the passage of a resolution against it in the state Assembly.

Punjab chief minister Amarinder Singh has also announced that the Congress state government is going to join Kerala in the Supreme Court in the case.
