Mangaluru: Two officials get 1 year jail for accepting Rs 3,000 bribe

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, Jan 7: Karnataka Chief Minister BS Yediyurappa on Monday said the much-awaited cabinet expansion will take place in about a week to 10 days and that he wants to complete the exercise before his proposed visit to Davos to attend the World Economic Forum meet later this month.

"Cabinet expansion has to be done in a week or 8-10 days. There is also information that Amit Shah will be coming to Bengaluru on January 16 or 18. Before that I will go to Delhi and get things cleared and will expand the cabinet at the earliest," Mr Yediyurappa said.

Speaking to reporters in Bengaluru, he said he wanted to complete the exercise before his Davos visit.

"I will make all efforts to expand the cabinet before that," he said.

With Mr Yediyurappa making it clear that 11 of the disqualified JDS-Congress MLAs who got re-elected in the December 5 bypolls on BJP tickets will be made ministers, lobbying has been on within the party for the remaining ministerial berths.

Currently, there are 18 ministers, including the Chief Minister, in the cabinet that has a sanctioned strength of 34.

Cabinet expansion will not be an easy task for the Chief Minister as he will have to strike a balance by accommodating the victorious disqualified legislators as promised and also make space for the old guards, upset at being "neglected" in the first round of the induction exercise.

He also has to give adequate representation to various castes and regions in his cabinet and also deal with the allocation of key portfolios.

The Chief Minister, who has indicated that the ministry expansion may take place any time after Sankranti, is likely to travel to Davos on January 20, according to sources.

BS Yediyurappa, along with Union ministers Piyush Goyal and Mansukh Mandaviya, as well as Chief Ministers Amarinder Singh, Kamal Nath, are expected to join over 100 Indian CEOs at Davos in Switzerland later this month for the WEF's 50th annual meeting, which will be attended by thousands from across the globe.

Mangaluru, May 8: Dr Arathi Krishna, former deputy chairman of Karnataka NRI Forum, today called on Karnataka chief secretary Vijaya Bhaskar and urged him to exert pressure on the Centre through chief minister to expedite evacuation of Kannadigas stuck in Saudi Arabia amidst covid-19 lockdown. 

She also conveyed the message from labourers in Gulf countries requesting for free quarantine facility upon their arrival. Positively responding to the demand, Mr Bhaskar said that free quarantine facility will be arranged at BSF base in Bengaluru apart from paid quarantine facility in different hotels and guest houses.

Dr Arathi Krishna told coastaldigest.com that she also spoke to the officials in-charge of Gulf in the Ministry of External Affairs  and requested them to take necessary steps to add more special flights from Gulf countries to Karnataka. 

The officials have promised to consider operating flight from Riyadh to Mangaluru via Dammam in the second wave of evacuation, the schedule of which is expected to be announced in a few days, she said.
