JD(S)-BJP likely to forge alliance for zilla, taluk panchayats

Bengaluru, Mar 22: Monday's only pending II PU exam (English) and SSLC exams scheduled to start on March 27 have been postponed due to Covid-19 concerns. The new dates will be announced in April first week.

The decision was taken after a meeting with chief minister BS Yediyurappa on Sunday morning, said state primary and secondary education minister S Suresh Kumar.

Around 8.25 lakh students are to appear for the Class 10 exam.

"I appeal to SSLC students not to get frustrated. I know you're fully prepared, fully geared up. But this is a peculiar situation which calls for hard decisions. The new timetable will be published very soon. Students should treat is as an extended study leave. Please revise more. Do not treat this as a relaxation time. You'll have plenty of time to relax after the exams," he said.

Bengaluru, Jul 1: Veteran actor and comedian, Rajagopal, who was known for his outstanding mimicry skills in Sandalwood breathed his last on the night of July 1, that is yesterday. He was one of the favourite comedians among the audiences and is said to have been suffering from kidney and asthma problems.

He passed away at his residence in Bangalore.

The well-recognised comedian has worked in more than 600 movies in his career, along with Tamil movies. The actor was active in the film industry since 1983 and had acted with many stars like Vishnuvardhan, Ambareesh, Prabhakar among others. He is also known for mimicking actress Kalpana's voice very well.

Recently, he also had claimed that new directors, new producers in the Kannada film industry had not been calling veterans to play parts in their movies and preferring fresh talent. He also had been going through a financial crisis due to the lockdown. Rajagopal has also worked in TV serials for some time in his career.  He has acted in super hit movies like, ‘Real Police’, ‘Sadakaru’, ‘Goosi Gang’, ‘Super Police’, and others as well.

The lockdown has seen the demise of many South Indian stars. Chiranjeevi Sarja too passed away last month, leaving the industry in shock. Now, a famous comedian's demise has also saddened the industry further.

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
