Eshwarappa not invited to BJP's OBC event

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Ernakulam, May 25: Miscreants belonging to self-proclaimed Hindutva outfits have demolished a church set erected for the shoot of a Malayalam film at Kalady in Kerala’s Ernakulam district.

The set was erected to shoot the climax scene of the super hero film Minnal Murali, directed by Basil Joseph and starring Tovino Thomas and newcomer actor Femina.

The incident took place on Sunday. Members of the Antharashtra Hindu Parishad claimed that with the help of their sister outfit Antarashtra Bajrang Dal, they demolished the church set, erected on an island on the Periyar river in Kalady.

Hari Palode, the General Secretary of AHP, an organisation founded by Praveen Togadia, boasted on Facebook that they were not used to pleading to anyone, and decided to demolish the church set that was constructed near the Adi Sankaracharya mutt. 

“When they built such a structure in front of the Mahadeva shrine in Kalady, we said no. We had also submitted several complaints. We do not have the habit of pleading. We decided to demolish it. Our self respect must be protected at all cost,” AHP’s General Secretary Hari Palode wrote on his Facebook post along with pictures of members demolishing the set. 

The post also credited members of the Anrarashtra Bajrang Dal and its Ernakulam Division President Malayatoor Ratheesh for participating in the ‘service work’ of razing the church set. 

Mini Biju, member of Kalady Town panchayat confirmed that the film unit had indeed secured permission from the department before going ahead with the construction of the set.

“They had submitted a letter seeking permission to raise a temporary set. This was back in February before construction began. The panchayat committee had approved this request,” Mini said.

Mysuru, Jan 11: Accusing the Congress and other opposition parties of pursuing “vote bank politics” on the Citizenship (Amendment ) Act (CAA), Kannada littérateur and Saraswathi Samman awardee S L Byrappa accused the party of misleading the people on the issue.

Speaking to media persons here on Friday, Mr Bhyrappa said that Congress was adopting the divide and rule policy of the British, who had created a rift between the Hindus and the Muslims to break their unity during the freedom struggle.
