Zakir Naik is a terrorist, behead him and win Rs 50 lakh: Sadhvi Prachi

Mangaluru, Jul 11: A youth was run over by a lorry after a speeding car knocked his two-wheeler down on Netravati Bridge near Thokkottu on the outskirts of the city today.

The deceased has been identified as Ubaid (28), a resident of Bandikotya in Ullal. According to sources, he was recently engaged and was supposed to get married on July 23.

Shakir, who was with Ubaid on the two-wheeler suffered serious injuries. He was shifted to a private hospital for treatment. 

The car hit the two-wheeler when the two were heading back to Ullal from Mangaluru. 

The impact of the collision was such that Ubaid was thrown on to the road. Within a second a speeding lorry crushed him to death on the spot. 

The car driver sped away after the mishap instead of stopping to help the accident victims. However, local residents chased the car and waylaid it near Thokkotty flyover. 

The car was reportedly driven by Krishna, who works at Someshwar municipality office. He had reportedly purchased the car just two days ago. Police have taken him into custody along with another person who was also on board the car.

Traffic south police have registered a hit-and-run case and investigations are on.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mumbai, Mar 26 : A 28-year-old man was arrested for allegedly killing his younger brother for stepping out of their home during the COVID-19 lockdown in the western suburb of Kandivali, police said on Thursday.Rajesh Laxmi Thakur killed his younger brother Durgesh after the latter stepped out of the house despite repeated warnings about the lockdown on Wednesday night, an official from Samta Nagar police station said.
