Gujarat varsity invites terror accused as chief guest for convocation

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Feb 12: Buoyed by the Aam Aadmi Party's stellar performance in the Delhi Assembly elections, the Maharashtra unit of the party has decided to fight all forthcoming local elections, including the Mumbai elections.

The AAP’s Bengaluru unit will also contest the municipal corporation polls likely to take place in August or September.

AAP National Executive Member Preeti Sharma Menon said the party will try to “replicate the Delhi model of pragmatism, performance, and people centric policies”.

“We are sure that Maharashtra will shower us with the same faith and love as Delhi has done so,” she said.

The party has decided to field candidates in all the 198 wards of the Bruhat Bengaluru Mahanagara Palike (BBMP).

"We have been planning to contest the BBMP election when we received a major shot in the arm. The Delhi victory happened because of the good work, which we want to replicate here," AAP's co-convener in Karnataka and party's BBMP campaign in charge Shanthala Damle told PTI on Tuesday.

Born out of an anti-corruption movement, the AAP led by Delhi chief minister Arvind Kejriwal registered the second landslide victory by winning 63 out of 70 seats in the Delhi Assembly elections.

According to Damle, AAP in Bengaluru was working in full swing to make its presence felt in the city. "The party has already done its ground workin terms of election campaign and reaching out to the people in Bengaluru," she added.

According to her, the party has already opened around 10 offices and about 50 people have been announced as the assembly president or ward president.

Last month, the party launched a 40-minute movie called 'Hosa Bengaluru' (New Bengaluru) and conducted 50 shows already.

"It shows the Delhi model and explains what can be done in Bengaluru. So that is part of our vision," the AAP leader said.

In its next level of the campaign, AAP intends to conduct 'Jana Samvada' (Dialogue with people) in every street and in every ward.

The preparedness of the party can be gauged from the fact that it has identified many of its candidates for the BBMP elections.

The party has never tasted success in Karnataka anywhere but the Delhi's success story has kindled a new hope as many people would now be waiting to join the AAP, Damle said. The AAP cadres in Bengaluru burst into celebration soon after it became clear that the party was going to script history by forming government for the third consecutive time since its inception.

Sporting their signature caps, party workers lit crackers, danced on the Delhi election song 'Lage Raho Kejriwal'.

Bengaluru, Jun 3: The Karnataka Institute of Medical Sciences at Hubballi has successfully treated a COVID-19 patient through plasma therapy, state medical education minister K Sudhakar said today.

"Karnataka achieves yet another milestone in battle against #COVID19. KIMS Hubli has successfully treated a Covid19 patient through Plasma Therapy & is the first institute in the state to accomplish this. Congrats to KIMS doctors & staff for this feat!" Mr Sudhakar tweeted.

In plasma therapy treatment, plasma cells from a COVID-19 patient, who has recovered from the disease, is transfused to a coronavirus patient who is in critical condition to treat him.

Plasma therapy was effectively used in the past during Ebola and the Spanish flu pandemic.
