HDK again offers support to BJP after bypolls, but BSY dismisses idea

Bengaluru, June 23: A frustrated chartered accountant has committed suicide after killing his wife and mother-in-law in two different cities of India.

The murder-murder-suicide came amid acrimonious divorce proceedings that might have also involved a property dispute, police said.

Amit flew to Bengaluru last weekend to kill his estranged wife at her Whitefield residence before returning to Kolkata, where he shot dead his mother-in-law and then killed himself at an upscale residential complex in North Kolkata on Monday evening.

Amit and his wife Shilpi Agarwal, who is also a CA, had been living separately since last the two years after their marriage turned sour.

Amit took his 10-year-old son from Bengaluru with him on Monday and dropped him at his uncle’s house before heading to his in-laws’ place Phoolbagan, police said.

Neighbours told cops they heard arguments “appeared to be” over some property documents that Amit wanted his in-laws — 70-year-old Subhas and 62-year-old Lalita Dhandhania — to sign.

The first gunshot was heard a little before 6.30pm, following which Subhas ran out of his flat, bolted the door from outside and took refuge inside his next-door neighbour’s apartment. Police arrived a few minutes later to find Amit and his mother-in-law dead. Police found a suicide note from the flat.

Mangaluru, May 15: In a shocking development, five residents of Udupi district, who recently came from United Arab Emirates today tested positive for covid-19.

As many as 49 passengers among over 175 repatriates who were brought from Dubai to Mangaluru International Airport on May 12 were from Udupi district.

Hence they were quarantined in Udupi district and their throat swabs were sent for testing on the same day. Today, five of them obtained positive report. They were today shifted to TMA Pai covid-hospital from their hotel rooms.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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