78 students withfake marks cards' barred from degree exams

Mangaluru, Feb 16: Leaving spectators awestruck, Karnataka's Srinivasa Gowda ran 142.5 meters in 13.62 seconds at traditional buffalo race Kambala, following which people started comparing him to former Jamaican Sprinter Usain Bolt.

Gowda, who is from Mudbidri town, accomplished the feat during a Kambala race in a paddy field in Kadri on February 1.

"People are comparing me to Usain Bolt. He is a world champion, I am only running in a slushy paddy field," said Srinivasa Gowda.

People took to social media and drew a parallel between him and Bolt. Twitterati hailed Gowda and his accomplishment on the muddy grounds.

Kambala is an annual buffalo race held in the southwestern state of Karnataka.

Traditionally, it is sponsored by local Tuluva landlords and households in the coastal districts of Dakshina Kannada and Udupi.

"I'll call Karnataka's Srinivasa Gowda for trials by top SAI Coaches. There's lack of knowledge in masses about the standards of Olympics especially in athletics where ultimate human strength & endurance are surpassed. I'll ensure that no talents in India is left out untested," Union Sports and Youth Affairs Minister Kiren Rijiju tweeted on Saturday.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Udupi, Jan 5: The district administration has identified 460 beneficiaries who will be allotted flats at Herga under the Pradhan Mantri Awas Yojana, informed MLA Raghupati Bhat.

Speaking to reporters here on Sunday he said the Udupi Municipal Council will construct the apartments in the 8.22 acres of land earmarked for the purpose at Herga. The flats will be ready before April 2021.
