Rs 1000, Rs 500 currency notes to be out of circulation from midnight

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Udupi, May 12: The Coastal Bus Owner’s Association members have approached Deputy Commissioner to permit them to run bus service in the District.

Nearly 80 buses coming under the Coastal Bus Association and they are prepared to run the buses as per the guidelines set by the government. They have also requested RTO officials for permission to operate and are awaiting approval. If the bus service starts operating, many workers like drivers, conductors, cleaners, mechanics will get employment.

Coastal Bus Owners Association President Raghavendra Bhat said that the bus owners must provide services to the public as per regulations set by Deputy Commissioner.

She is one of a few beauty queens who give equal importance to both modelling and academic growth. Within months after completing her MBA in Finance and HR, Shifali Saldanha won Miss India Continent 2019 first runner-up and Miss Glory of International 2019 held in Mumbai.

An alumna of St Aloysius College (AIMIT), this 23-year-old Mangalurean is now a much sought after budding model. “I am enjoying the moment and would like to go with the flow,” says the much-loved daughter of Stephen Saldanha and late Anupama Saldanha.

Over the course of past two years, Ms Saldanha has experienced various nerve-wracking moments. She was shattered when her beloved mother lost battle with cancer and bid adieu to the world a couple of years ago. Yet, she serenely braved all the challenges. Her ‘never give up’ attitude helped her to scale new heights amidst misfortunes and pains.

Speaking to coastaldigest.com about her success in Miss India Continent 2019, which was organised by Dr Mahesh Yadav of Aman Gandhi Film Productions, Ms Saldanha said 15 contestants from different parts of the country were shortlisted for the finale, which had five diverse rounds. 

“The meet and greet session was my favourite phase in the competition as it was an opportunity to interact with the participants from different parts of the country,” recalls the multi-talented, who dreams big. 

The leggy lass’ success wasn’t accidental one. A trained singer and multilingual anchor, Ms Saldanha was already a known figure in coastal Karnataka. She had won the titles Miss Karnataka International- Multimedia 2018, and Miss Beautiful Eyes Mangaluru 2018.

Being a moderate feminist, who carries a go-getter attitude, Ms Saldanha calls upon every woman to be optimistic, challenging and goal-focused.
