Accused of molesting 13-yr-old girl, Kabaddi coach hangs himself in hotel room

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 20: Amid calls for boycott of Chinese products in the backdrop of Indo-China border face-off, former Karnataka chief minister HD Kumaraswamy sought to know from the BJP government in Karnataka the status of the "Compete with China" policy brought during the previous JDS-Congress rule.

Boycotting Chinese products was not easy like sloganeering but required a creative policy and the coalition government's initiative was a model for it, he said in a series of tweets.

"After the border skirmish, some people got the realisation to boycott the Chinese products but during my tenure (as chief minister) a serious thought was given to it," the JDS leader said.

He was apparently referring to growing clamour for boycott of China-made products after a violent clash between Indian and Chinese troops in the Galwan Valley in Ladakh left 20 Indian Army personnel dead early this week.

Mr Kumaraswamy said he had brought the Compete With China policy to effectively deal with the neighbouring country.

"My government's objective was to offer jobs to the local residents, snatch away market opportunities for China and discard the Chinese products."

"However, what has the present government done to our scheme? It is not known whether it is still continuing or not," Mr Kumaraswamy said.

The Kumarswamy government had identified clusters and earmarked Rs 2,000 crore for their development.

Mangaluru, Jan 30: A day-long ‘satyagrah’ by women followed by formation of human chain marked the Martyrs’ Day, the death anniversary of Mahatma Gandhi, in Mangaluru.

The organisers were ‘We, the People of India’, whose sole intention was to safeguard constitution of India and raise voice against those to attack the constitution.

Amidst nationwide agitation by ‘We, the People of India’ against contentious CAA, NRC, the women of Manglauru have decided to hold satyagrah and form a human chain in front of the office of the Deputy Commissioner in the heart of the city on January 30.

The Satyagrah commenced at 10 a.m. At 4:30 p.m. a human chain will be formed. At 5.17p.m. when the father of the nation was gunned down 72 years ago during his evening prayer at Birla House by Godse, the demonstrators raised the slogan of unity to defeat the ideology of Godse.
