KFDC chief bats for ban on fish export from Karnataka to check rising prices

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bandipur, Jan 28: British adventurer Bear Grylls and superstar Rajinikanth arrived at the Bandipur Tiger Reserve and National Park in Karnataka on Tuesday for shooting a special episode of the show 'Man vs Wild'.

The actor arrived at the location dressed in comfortable sporty clothes. Donning a dark blue jacket and grey track pants, Rajinikanth was also carrying a cross-body sling bag.

Videos and photographs of Rajinikanth arriving at a helipad were shared widely on social media.

Reports say that an agreement was signed between the Karnataka Forest Department represented by the Field Director of Bandipur and Banijay Group, Seventaurus Entertainment Studio Private Ltd, Mumbai for shooting of the documentary in December 2019. The team was also allowed to do a recce from December 27th to 29th as per the agreement, a report said.

The shooting has been permitted for six hours. "Permission for the shooting has been given for Sultan Batteri highway and ranges of Mulleholle, Maddur and Kalkere ranges. They will be shooting in non-tourist zones. If permission was given for the shooting of Wild Karnataka, then this can also be permitted. Also, no tourist or regular forest patrolling activities will be affected. The shooting will be done under special forest protection and no one will be aware of the locations," a forest official was quoted as saying in another news report.

Earlier in 2019, Grylls shot an episode of the show with Prime Minister Narendra Modi.

Grylls is also back with the latest edition of his National Geographic show ‘Running Wild With Bear Grylls’, where actors such as Channing Tatum, Brie Larson, Joel McHale, Cara Delevingne, Rob Riggle, Armie Hammer and Dave Bautista take on adventurous challenges in remote wilderness.

Bengaluru, Jan 25: To address the grievances of the Industrialists, over the issue of acquisition of land, the state government have plans to dilute the Land Reforms Act, Chief Minister B S Yediyurappa, said here on Saturday.

Speaking to the media here, on his visit to the World Economic Forum, Davos, recently he said that 'the visit was fruitful and ends with satisfactory note by procuring promises from several Industrial houses to investment in Karnataka'.

Stating that during his five-day stay at Davos, he had met several Industries heads on the sidelines of the summit, and had an interactive meeting with them, Chief Minister said that 'the event had helped us to present our state Karnataka, to convince them about the prevailing industry-friendly environment'.

He said that he had met several heads of global companies, including Arcelor Mittal, Kirloskar, MAHINDRA, Bharat Forge, 2000 Watt, general electrical, Dassault, Dalmia, Lulu Group, Volvo, Nova Nosdik and Domeco.

'The interaction with the corporate heads was encouraging and more investment is expected to flow into Karnataka, in the fields of Mining, Power, Agriculture, Pharma, Education, and Industries.'

Informing that the main grouse expressed by the Industrialists about the bottlenecks being faced in the Land Reforms Act to procure land, he said that 'To make ease of conversion of Agricultural land we have plans to bring amendment and it would be both win-win situation to both Farmers as well as Industries.'

'We have promised them to remove all hurdles, which comes in the way of acquiring land to set up industries, and we have promised to rectify all the administrative problems within a month or two and legal problems in the next couple of months by amending existing laws.'

'We have also plans to present a new Industrial policy in the coming budget and roll out a comprehensive and investor-friendly law', he further said.

Replying to questions, Chief Minister said that 'all those investment proposals which got clearance at the High-Level Clearance Committee would automatically considered as ‘deemed permission’ and start the process of acquisition of land'.

'TheWorldEconomic Forum Summit had also served us as a platform to invite Industrialists to take part in the Karnataka Global Investors Meet scheduled to be held in November this year', he added.
