Gold smuggled in by Mangalurean via imported Mini Cooper car seized

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, Jul 19: In the wake of the COVID-19 lockdown imposed till July 23, streets in the Dakshina Kannada district here bore a deserted look today (Sunday) morning.

The state government had allowed relaxation hours between 8 am to 11 am in the week-long total shutdown. However today there was no relaxation.

Bengaluru, Jan 11: Scholar and writer M Chidanadamurthy passed away at a private hospital here on Saturday.

He was 88 and is survived by wife, son and daughter.
He was a well-known scholar in Karnataka specialising in the history of Kannada language and ancient Karnataka.

He was also known for his campaign to conserve the monuments Hampi and to secure classical language status to Kannada Language. Murthy has also articulated that uniform civil code and an anti-conversion law must be enacted by the Government in India.

Murthy was the head of the department of Kannada Bangalore University. He was also associated with Kannada Shakti Kendra. As a historian most of Murthy's work has focused on scientific study of the Kannada Inscriptions.

He has attempted to contextualise inscriptions in their socio cultural setup. He has produced many books on the history of Kannada language and Karnataka. He has guided many research students.

Murthy was recipient of Rajayothsava, Sathiya Academy Award , Papama award and Alava’s Nudisiri award.
His mortal remains were kept at his residence for his fellow mates and relatives.

Several dignatories like B S Yediyurappa, S L Bhyrappa, S Suresh Kumar, V Somanna expressed their condolences to the veteran's death.
