Fingers, hands raised against PM Modi will be chopped off: Bihar BJP chief

Bengaluru, May 5: The movement of migrant labourers from Karnataka to other states has stopped temporarily, as few North Indian states are yet to give consent.

Revenue Minister R Ashok said that the state government will convince labourers to stay back and ensure free food supply at their camps. "Even if we allow them to travel, they will be quarantined for 14 days as soon as they reach their native states.

The labourers don't know about this and some states have not yet given permission for their return," Revenue Minister R Ashok said.

According to sources in CMO, the decision to convince the workers to stay back came after several major projects - both government and private - were affected by the mass migration of labourers to their native districts and states.

Ashok, along with S Suresh Kumar, Primary and Secondary Education minister and head of the group of ministers focusing on migrant workers, also visited labourers who had gathered demanding that they be allowed to return.

Chief Minister BS Yediyurappa will chair a meeting tomorrow and instruct builders under CREDAI to pay pending wages of labourers, provide food supply and ensure their safety, Ashok said, adding that all construction work by BBMP will also be taken up to help the labourers.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Mar 13: Several ministers staying at the Bengaluru resort had been emotionally pressurised to leave the Congress party, said Congress leader Jitu Patwari on Thursday after he was rescued by party leader DK Shivakumar from getting arrested due to the scuffle that had broken out at Embassy Boulevard here.

"We had received information that one of the MLAs, Manoj Chaudhary, staying at the Boulevard wanted his father to bring him back home," Patwari told reporters.

He said, "We had accompanied Manoj's father to the resort but the moment we entered the restaurant at the resort, some miscreants took away Manoj to some other unknown place," Patwari told reporters.

"Meanwhile, we (Lakhan Singh and Jitu Patwari) were manhandled and taken to the police station," he added.

Patwari said that the police had started the process of arresting them but Shivakumar came to their rescue and stopped their arrest.

He further said, "The police manhandled us even though we tried to talk to them in a very calm manner."

"If the MLAs giving resignation was their decision then why is the BJP not allowing them to contact their families," the MP said.

He further said that Jyotiraditya Scindia would soon become a minister but "why are the other ministers being made scapegoats."

Earlier in the day, a Congress leader in Madhya Pradesh had said that if action on the assaulters of its two leaders is not taken then the matter will be taken to the court.
