How these Karkala siblings fought poverty, disability to clear PU Board exams

Mangaluru, June 21: A local court has held notorious serial killer Cyanide Mohan Kumar guilty in the murder of a 25-year-old woman from Kasargod. This is the 20th and the last case of Cyanide Mohan to be tried in the sixth additional district and sessions court. 

According to public prosecutor Jayarama Shetty, the victim was working as a cook in a ladies hostel and got in touch with Mohan Kumar, a teacher. He visited her house thrice and promised to marry her. On July 8, 2009, on the pretext of visiting a temple in Sullia, she left home, never to return. 

They had travelled to Bengaluru and three days later, when her family tried to reach her on phone, he told them that she had gone for a bath and that they were married and would be returning back home soon.

The next day Ramakrishna, a constable from Upparpete police station, found a lady lying unconscious outside the bathroom and he immediately rushed her to a local hospital, where she was declared dead on arrival. Like in all other cases, after staying in a lodge and having sex with the victim, he took her to the KSRTC bus stand and asked her to consume a cyanide laced tablet, stating it was a contraceptive pill. 

He asked her to leave behind the jewellery that she was wearing at the hotel room. An unnatural death report was registered and since none of her relatives had turned up for identification of the body, on July 15,2009 the body was buried.

The moment the Dakshina Kannada district police arrested the serial killer on October 21, 2009 and his pictures were all over the media, the family recognised him and the victim’s younger sister filed a missing complaint. The police had also recovered the victim’s jewellery from the house of Mohan’s second wife and the jeweller from whom he had purchased cyanide had also identified him. Meanwhile, the CID had taken over the case and a charge sheet was filed.

"The report from the Forensic Science Laboratory is crucial in this case as cyanide was found in the victim’s viscera. Mohan over the years has become a legal expert and in this case, he had sought two adjournments," said Jayaram Shetty. Mohan is currently lodged in the Hindalga central jail.
 

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

Shivamogga, Apr 13: Banana farmers in Shivamogga say their crop is rotting and they are incurring huge losses amid lockdown due to COVID-19.

The farmers alleged that although permission has been granted for the sale of agricultural products, with inter-district movements being affected, the local buyers are forcing the farmers to sell their produce at ridiculously low prices.

"Local buyers are asking us to sell bananas at Rs 4-5 per kg which is impossible for us. I do not know what we can do," Vijayendra, a farmer told ANI here.

"We expected the markets to be good during the summer season, I have cultivated bananas in four acres of land. There are thousands of other farmers who cultivate it in smaller hoardings," he added.

The farmer further implored the government to ensure there is an open market and inter-district movement of agricultural produce is allowed to ensure the farmers get the right price.

Vijayendra also said that the bananas have started rotting as they were not being harvested due to the lockdown.

Prime Minister Narendra Modi had last month announced a 21-day lockdown in the entire country effective from March 24 midnight to deal with the spread of coronavirus, saying that "social distancing" is the only option to deal with the disease, which spreads rapidly.

There is also the likelihood that the nationwide lockdown might further be extended even after the completion of the 21-day period on April 14, based on the statements from several chief ministers following a video conference with the Prime Minister held a few days earlier.
