28-yr-old woman in 8th month of pregnancy hacked to death in Bengaluru

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, Feb 26: The 'Yakshagana' stage in Karnataka is witnessing a curious spectacle with a Muslim woman artiste creating waves with her performances.

Arshiya, the artiste from Vittal in Dakshina Kannada district, is the first woman from the Muslim community to venture into the popular traditional theatre art form.

At one time, women were barred from Yakshagana stages.

A Muslim woman exponent on stage has attracted the attention of 'Yakshagana' lovers in the state.

Arshiya is now getting advanced training in her skills at the Kadali Kala Kendra under Ramesh Bhat here.

Arshiya, who is fond of 'Bannada Vesha' (villain roles), is now known in her stage name 'Tanu Vitla.'

She has already performed various episodes on stage and gained popularity.

Arshiya, currently working in an automobile showroom at Padil, said she was attracted to the art form from a very young age.

The initial enchantment with the art form came as she saw the role of Mahishasura in 'Sri Devi Mahatme Yakshagana Prasanga' (episode) performed near her home town.

She was attracted to all the elements of the art form, which combines music, percussion, dance, dialogues, stage techniques, make-up and costume.

Arshiya said she was also inspired by a teacher in her school at Vittal who trained her for a performance on stage during the school's annual day celebration.

She started performing on local stages at Vittal at the very young age of 10.

Arshiya now performs prominent roles on stage including Mahishasura in Sri Devi Mahatme Prasanga, the role which enamoured her in her childhood.

She also has donned the roles of Nishambhasura, Rakthabeejasura, Srinivas Kalyana, Sudarshanopakyana, Kadamba Kaushike and Shambavi Vijaya.

Her performances at Udupi and Karwar besides Mangaluru have earned her a lot of admirers, who love her 'Asura' roles, thanks to her loud voice.

Arshiya now wants to learn the 'Chende' (percussion instrument), which is an important element in Yakshagana performances.

Arshiya revealed that there was a bit of resistance from her community about her passion for the art form, but she had staunch backing of her family.

Shivamogga, Jul 24: The protest by Accredited Social Health Activists (ASHA) under the All India Trade Union Congress (AITUC) entered its 14th day on Friday demanding personal protective equipment (PPE) kits and a salary of at least Rs 12,000 per month.

They have been protesting in different parts of Karnataka since July 10.

Staging a protest in front of the deputy commissioner's office, the ASHA workers complained of the government turning a deaf ear to their problems.

Clad in their signature pink saris, they raised slogans to demand appropriate salary for their work and the necessary equipment to protect them from the ongoing COVID-19 outbreak. 

They said that they worked tirelessly during the COVID-19-induced lockdown without any safety. The department only provided them with sub-standard equipment to combat the deadly virus. All they were asking for is a basic pay of Rs 12,000 against the current pay of Rs 6,000.

Prema, an ASHA said, "The authorities are praising our work, clapping for us and showering flowers on us but are not listening to our grievances."
