Women get raped if they attend unwanted parties: Bharathi Shankar

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 24: The JD(S) is looking to leverage anti-Citizen (Amendment) Act (CAA), National Register of Citizens (NRC) and National Population Register (NPR) sentiment sweeping the country to revive itself and will hold protests in Bengaluru and New Delhi.

The Bengaluru protest is scheduled for Friday. At a meeting of party workers in Bengaluru on Thursday, party patriarch HD Deve Gowda and former chief minister HD Kumaraswamy urged the rank and file to participate in the rally to send out a loud and clear message to the BJP.

"The BJP has set out to make Muslims second-grade citizens. India has 40 crore Muslims, can these communal forces eliminate them all?" Gowda said in his address. "We should have the guts to launch a massive protest at Jantar Mantar. We should be prepared to go to jail in the fight against [Prime Minister] Narendra Modi and [Union home minister] Amit Shah."

Gowda said he will lead the rally in Delhi and urged secular parties to unite to take on the BJP. "It is important that regional parties, which share a secular ideology, unite on a common agenda and fight the BJP. Bihar, Kerala and Odisha have said they will not implement CAA. The sentiment is likely to spread to other states," Gowda said.

Kumaraswamy said not only Muslims but many other communities will also bear the brunt of BJP’s "divisive politics". "This pair of Hakka-Bukka [Modi and Shah] is not targeting Muslims alone," he said. "For them, all communities other than upper caste Hindus are inferior Shudras. They will treat even Lingayats, Vokkaligas and Dalits with the same contempt."

The former CM made a special appeal to Lingayats, who generally back the BJP, to stop supporting the saffron party’s caste-oriented politics. "You had appreciated my farm loan waiver scheme and promised support in the elections. But, the results were contrary to that," he said.

The JD(S) passed three resolutions including one to condemn the Centre for enacting CAA. The others were to protest against the Centre’s indifference to the floods in the state and the failed economic policy of the Centre.

Kasaragod, April 9: After Supreme Court intervened and settled the Border issue with Karnataka authorities who had consented to allow the critically-ill patients from in and around Kasaragod and nearby areas to cross over to nearby Mangalore for getting urgent and critical care treatment, the Karnataka authorities is alleged to continue to be hostile either by blocking way ahead or turning a deaf ear to the patients reaching there.

It was on Wednesday onwards that the check post at Thalapadi near here on the Kozhikode-Mangalore National Highway was opened for the critically-ill patients to cross over to Mangalore hospitals for medical treatment.

However, reports reaching here said two out of the three critically-ill patients, who made it to Mangalore were allegedly ill-treated or given no treatment forcing them to return back to Kerala.
