Is BJP ‘Beef Joy Party’ now? VHP asks after Parrikar’s assurances to beef eaters

Mangalore, Jan 1: Under the aegis of the Dakshina Kannada District Jatyateeya Paksha Sanghatanegala Janti Vedik, Members of Congress, Communist Party of India, CPI (M), Janata Dal (Secular) and other secular organisations will stage a dharna on January 2 here demanding a judicial inquiry into the firing on December 19.

Talking to reporters on Tuesday evening, former Bantwal MLA B Ramanath Rai said the dharna will be held before the statue of B R Ambedkar, near the Town hall, from 1000 hrs to 1600 hrs.

Mr Rai said allegations are being made that the trouble in the city on December 19 was orchestrated by certain political parties and leaders. The city police are also being accused of acting under the influence of the ruling government in invoking prohibitory orders to quell the protest against the Citizenship Amendment Act (CAA) and later firing at the protesters that led to two deaths.

Bengaluru, Apr 5: An elderly couple from Bengaluru

with a travel history to Dubai joined the list of coronavirus patients in the state, taking the total number of cases to 146, the health department said on Sunday.

The list includes four deaths and 11 discharges.

The 68-year old man and his 62-year old wife, hailing from Madiwala in the city, had returned from Dubai on March 22.

They were quarantined at a private hospital and have been asymptomatic.

Meanwhile, the government appealed to people who had attended the Tablighi Jamaat Congregation in New Delhi to contact 080-29711171 Arogya Sahayavani, the medical helpline number.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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