Modi conferred Saudi Arabia's highest civilian honour

Hubballi, Jan 6: Elected representatives of the BJP, Congress and JD(S) on Sunday decided to sink their differences and fight unitedly for Karnataka’s rightful share in the Mahadayi and Kalasa-Banduri water dispute with Goa.

The meeting convened by JD(S) MLC Basavaraj Horatti here saw participation of BJP ministers Prahlad Joshi and Jagadish Shettar, Congress and JD(S) lawmakers, among others.

After a 70-minute closed door meeting, MLC Horatti told reporters that they discussed the water dispute in detail and decided to take steps based on inputs from legal and technical experts on the rightful apportioning of water. “Today, we took the first big step towards the overall development of the region, unencumbered by political divisions,” he said.

Though the air was filled with a sense of jubilation as the issue had united seemingly hostile political parties on one side, a few activists expressed disappointment that the meeting failed to set a timeline to resolve the dispute.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mysuru, Feb 14: Two weeks after her engagement with another boy, a 20-year-old girl who was in love with a boy, committed suicide at her residence in Nanjangud on Wednesday.

Meghana's parents have accused her lover Manikanta of Hemmargala of abetting her suicide. The girl's father in his complaint has claimed that Manikanta threatened to send their photos to her fiance following which she took the extreme step. He has also claimed his daughter was molested by Manikanta two years ago.

Manikanta who is on the run has been booked for rape and abetting suicide following the complaint.

Since the girl was from the SC community, cops have also slapped cases under Atrocities (Prevention) Act against Manikanta. Nanjangud sub-division DSP Prabhkar Rao Shinde will investigate the case as charges have been made under provisions of the act.
