Shocking! Cops fight like dogs on road over share of bribe; video goes viral

Mangaluru, Apr 13: City Commissioner of police P S Harsha on Monday warned people, not to use drones illegally for filming or any other purposes.

Speaking with this regard Harsha said on Monday ,''“We have noticed that persons are illegally using drones to film Mangaluru city. If this continues, we will not only seize the drone but will also take firm legal action against the person responsible. Because Mangaluru is a sensitive place with lots of vital installations.''

He further requested the media houses also not to hire drone services for filming or any other purposes.

Mangaluru, July 10: Dakshina Kannada, which has emerged as one of the hotspots of covid-19 in Karnataka, has recorded at least six novel coronavirus related deaths in past 24 hours. 

According to sources, four people lost their battle with the novel coronavirus in Wenlock, the designated covid hospital. 

A 35-year-old man from Hosabettu, who was tested positive for COVID-19 recently, died at the Wenlock COVID hospital in the morning.

A 58-year-old woman from Thokkottu, a 67-year-old man from Ullal and a 65-year-old man from Falnir also passed away in the same hospital. 

Two other covid patients passed away in private hospitals. 

With this, the total number of death of covid patients in the district rose to 36. 

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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