Hadiya marriage: Kerala govt rubbishes NIA’s shocking claims

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

New Delhi, Jan 20: Union Finance Minister Nirmala Sitharaman on Sunday said the kind of cleaning in the system that the BJP-led government had to carry out after coming to power in 2014 was "unbelievable" and it undertook the exercise without any grudge or worry.

Between 2014-16, there were a lot of questions as to why reforms did not come fast and there were comments that the government was incapable of bringing them, she said delivering the Nani Palkhivala Memorial lecture on "Road Map to $5 Trillion Economy" here.

Pointing out that there were allegations and criticism that the government wants to do something but it did not, Sitharaman said, "I am fully willing to buy that." She recalled that Prime Minister Narendra Modi often said he did not believe in incremental changes and the country needed good transformational change. The stage in which India is today, it cannot have little marginal increments, but good transformational change.

"But still one might say in the last five years the government never did. That can be a critical analysis and I am fully willing to buy that. Because post-2014 the kind of cleaning up the government had to do was unbelievable and we undertook that exercise without a grudge without a worry.. we had to do it and it is part of the game," she said. Elaborating, Sitharaman said states have their own views on Land Acquisition Bill and the government could not have done anything because land, after all, is with them.

Commenting on the topic 'Road Map to $5 trillion economy,' she said quoting Prime Minister Narendra Modi's comments, the government would take the route "Sarkar ka abhaav nahi hona chahiye, prabhaav hona chahiye aur dabaav nahi hona chahiye."

"Abhaav and dabaav both of which are not desirable, abhaav is the inadequacy or lack of adequate presence or shortfall. You do not need a shortfall. You need a government where it should be present, where it is expected to function.", she said.

"So there should not be abhaav. Dabaav (meaning pressure) is not something you want from the government. So, you want Prabhaav. It is broadly an influence, facilitation, broadly the philosophy with which it is mandated, she said.

Noting that the government has got the mandate through the election, she said, "The mandate was spelt out in so many different ways in its manifesto. So the route towards $5 trillion is this."

"We have to be there to facilitate. We have to be there to make it easy. We have to be where you need us, where there is no policy (reforms from the government)," she said.

On the Insolvency and Bankruptcy Code (IBC) implemented by the government, the union minister said the approach of the IBC was not to shut business. "IBC takes on the approach in having some kind of resolution where all people who exploited the company do not come back through the "back door," she said.

IBC was done through better management so that the institution is alive and kicking. It is something which she wanted to carry forward from Modi 1.0 to 2.0. "The point I am trying to make on this road to $5 trillion economy is that it is not just an abstraction, this is not how I want India to be. But in micro-level too, we are coming in response to every stakeholder," she said.

Lucknow, Mar 5: Uttar Pradesh chief minister Yogi Adityanath said last night that the role of teachers would come under the scanner when "anti-India" slogans are raised at universities and institutions of higher education.

"When anti-India slogans are raised at institutions of higher education, we should be prepared to ask why this type of distortion occurrs among our students?" he said at a programme organised by the Basic Shiksha Parishad in Lucknow.

"We begin our work with pledge for the country's unity and integrity and today slogans are raised for the division of the nation. In such a situation, questions are raised over the role of teachers who are considered equal to god in society," he said.

"Who all are involved in this sin and chaos? Governments can provide resources, but the one who has given them basic education, who has given them secondary education and who has led them to that place, all of them should evaluate their actions today," the chief minister said.

Speaking about the condition of education in the state when his government came to power three years ago, he said there was an atmosphere of chaos and anarchy in the state and the condition of basic education was very bad.

"The worst problem was that of proxy teachers. Our government started the process of prohibiting proxy teachers in the first phase," he said.

Adityanath said that a teacher is not just a government servant, but the fate of the nation. He said teachers should learn from Chanakya.

Had Chanakya confined himself to Nalanda University, he would not have been able to make India a superpower of the world during that period. Teachers will have to prepare themselves according to the challenges and need of society, he added.
