Jan 14: A day after it moved the Supreme Court against the controversial Citizenship Amendment Act (CAA), the Kerala government on Tuesday said it would continue its fight against the legislation as it "destroys" the secularism and democracy in the country.

The CPI(M)-led government had on Monday moved the apex court challenging the CAA and sought to declare it as 'ultra vires' of the Constitution. State Industries Minister E P Jayarajan told reporters here that the state has moved the apex court and will explore all options to fight the Act.

"The state government will to go to any extent and continue its fight against CAA. This Act destroys democracy in the country. This will only help in implementing the RSS agenda, to drive the nation through a fascist regime, and destroying the secularism and democracy in the country. The RSS and the Sangh Parivar cannot implement this law just by using muscle power," Jayarajan said.

Tourism Minister Kadakampally Surendran tweeted that the state became the first in the country to approach the top court against the Act. "Kerala government files lawsuit against the unconstitutional CAA. Kerala becomes the first state in the country to go to the Supreme Court against CAA.

"Kerala leads the way," he said in the tweet. In a suit filed in the apex court, the Kerala government has sought to declare that the CAA 2019 was "violative" of Article 14 (Equality before law), 21 (Protection of life and personal liberty) and 25 (Freedom of conscience and free profession, practice, and propagation of religion) of the Constitution.

It also claimed that the law was violative of the basic principle of secularism enshrined in it. The state Assembly had on December 31, 2019, passed a unanimous resolution against the CAA and became the first state to do it.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 1: Karnataka government along with BBMP has asked project contractors, builders and developers in the city not to send their labourers to their native place and instead provide them with amenities like food and shelter in this lockdown period.

It was also warned with legal action would be taken against them if they violating the instructions from the government .
