Siddaramaiah running govt like 'Tughlaq darbar' ahead of polls: Yeddyurappa

Udupi, Feb 11: In a tragic incident, a 62-year-old man from Chennai died of drowning in Sri Krishna Mutt’s Madhwa Sarovar (pond) during the wee hours of Tuesday.

Police said the deceased has been identified as Capt G Sridharan.

It is suspected that Sridharan accidentally fell into the holy pond while taking a bath. The incident is said to have occurred around 4 a.m.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

With an aim to provide water to stray animals in Mangaluru, an animal activist announced a project 'Jal' under which free water bowls will be distributed to the people across the city.

Tauseef Ahmed believes many animals and birds do not find source to drink water which leads to death.
"Finding clean and safe drinking water has been a major issue in a lot of places. We humans when we face some scarcity we manage by taking the water out from the well," Ahmed told ANI.

"Unfortunately, that's not the case with when it comes to animals and birds. They do not find sources for water to drink so they eventually end up drinking sewage water and they fall sick. In some cases, even that is not available and due to dehydration, they die," he added.

Under the "Jal" project, Ahmed will distribute free water bowls to the people and expects them to make equal efforts in saving the lives of the animals.

"So, this project "Jal" will be providing 100 free water bowls all over Mangaluru. We are distributing it free of cost. All you have to do is keep the bowls outside in the garden or any places where animals frequently visit. Every day, we just have to fill the bowls with water for the animals. It will help a lot of animals to survive in the harsh weather of summers," Ahmed highlighted.

"We have used cement to make the bowls which will keep the eater really cool. We are spending close to 74 rs per bowl. We have made around 100 bowls and will continue making it. We are trying to cover as many animals as we can," he said.
