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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Kochi, Jul 12: The two main accused in Kerala gold smuggling case, Swapna Suresh and Sandeep Nair have been arrested by the National Investigation Agency (NIA). Both the accused will be produced before NIA court in Kochi, Kerala on Sunday.

Swapna Suresh and Sandeep Nair were detained by NIA from Bengaluru, Karnataka on Saturday.

Swapna is named as the second accused and Sandeep has been named as the fourth accused in the FIR taken by NIA and both have been slapped with Unlawful Activities (Prevention) Act, 1967, (UAPA) along with first accused Sarith PS and third accused Fazil Fareed
Already, Sarith PS was arrested by the Customs, while Fazil Fareed is still at large. 

NIA officials yesterday conducted a detailed interrogation of Sarith after reaching the customs office in Kochi where he is in custody.

The Customs Department had on July 5 seized 30 kg gold worth Rs 15 crore concealed in diplomatic consignment at the Thiruvananthapuram international airport.

The NIA on Friday registered a First Information Report (FIR) against Sarith Kumar, Swapna Suresh and Sandeep Nair, the three persons allegedly involved in the case.

The agency has charged them with offences under various sections of the Unlawful Activities Prevention Act.

Swapna Suresh was on the run following the gold seizure. She was employed in Space Park and Kerala State Information Technology Infrastructure Limited (KSITL), which comes under the IT department, a portfolio held by Kerala Chief Minister. She was ousted after being named an accused in the case.

Sarith Kumar, an accused in the case who had previously worked as a public relations officer (PRO) in UAE Consulate-General's office in Thiruvananthapuram, was arrested on July 6.

Bengaluru, Jan 24: Middle East based prestigious LuLu Group has come forward to invest $300 million in Karnataka in the retail, logistics and hospitality sectors.

As part of this, the first LuLu mall will commence operations in Bengaluru’s Rajajinagar area by August.

LuLu’s first mall in India, in Cochin, is seen as a huge success. It’s not clear how that mall is doing financially, but it became so popular that it had an adverse effect on almost every other mall in the city.

Lulu’s investment plan for Karnataka was communicated during a discussion between chief minister BS Yediyurappa and Yusuff Ali MA, chairman and managing director of Lulu Group, on the sidelines of the World Economic Forum in Davos.

The company will also set up two five-star hotels in Bengaluru through Twenty14 Holdings, its hospitality arm, and a modern logistics centre in the Uttara Kannada region.

Lulu Group’s retail initiative Tablez brought Toys `R’ Us, one of the world’s largest toy store chains, to Bengaluru in 2017. Started in the Phoenix Mall in Whitefield, it competes with Reliance-owned Hamleys.

Tablez has also brought in other international brands such as American ice cream parlour chain Cold Stone Creamery, South Africa based flame-grilled chicken concept Galito’s, and Tablez’ own brand Bloomsbury’s, a boutique cafe and bakery. It has also launched Spanish fashion brands Springfield and Women ’secret.
