Expectations high in Dakshina Kannada as SSLC exams begin

Hubballi/Vijayapura, Feb 26: A 40-year-old resident of Talikoti town in Vijayapura was arrested on Tuesday and charged with sedition for allegedly saying 'I Love Pak Army' on a social media page and sharing a video of a song, 'Pakistan Zindabad'.

Police said they registered an FIR against Meru alias Merusab Hasansab Byagwat on a complaint filed by a contractor, Ashok Rathod of Nebgiri Tanda.

Byagwat has been booked under IPC sections pertaining to sedition (124A), promoting enmity between communities and making assertions prejudicial to national integration (153 A & B), among others.

In his complaint, Rathod said Meru had posted the video on his social media account on February 22. Rathod said he took a screenshot of the video and made some inquiries before approaching police.

Police said Meru would be produced in court soon.

Police said they are keeping a watch on pro-Pakistan activities. On Monday, slogans praising Pakistan surfaced on the walls of a government primary school in Budarsinghi. In the third week of February, three Kashmiri students shot a video hailing Pakistan and circulated it on social media in Hubballi.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Feb 9: A youth, native of Dakshina Kannada, was kidnapped and later robbed and then abandoned by a group of criminals, after he landed at the Karipur International Airport in Kerala early on Sunday morning.

In a complaint filed with the Kondotty police, the victim identified as Abdul Nazar Shamsad, said he was kidnapped while he was travelling in a shared auto from the airport to Calicut town. The kidnappers took him to an unknown destination where they tortured him.

Shamshad was reportedly subjected to physical assault and was asked to hand over the gold that he carried with him. It is learnt that the kidnappers had mistaken the youth for a gold smuggler and tortured him in order to get hold of the smuggled gold. They also stole his money and documents before abandoning him.
