Puttur, Jan 4: As many as 27 passengers travelling in a private bus escaped with minor injuries after it toppled and fell into a roadside trench at Amai near Perne on Mangaluru-Bengaluru national highway last night, police said on Saturday.
Police said that the driver of the Bengaluru-bond bus lost control over the vehicle while traversing through the narrow bridge at Amai.
The bus was damaged in the mishap.
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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 8: A speeding car fell off the newly-inaugurated Pumpwell flyover in the city after jumping the median and ramming into an oncoming car today.
At least four persons have suffered injuries in the mishap involving a Maruti Alto and a Renault Duster. The condition of two is said to be extremely critical. The other two have suffered minor injuries.
The accident took place when the driver of the speeding Alto which was heading towards Kasaragod from Udupi lost control over his vehicle.
Towards the end of the flyover, car rammed into the divider and then hit the ill-fated Renault Duster which was coming from the opposite direction. The Alto then fell off the bridge.
The accident caused traffic jam on the highway for some time. The flyover was inaugurated a week ago, after a decade long wait.

this is one of the important case that now seen to be increasing these days. and one of the most problem that is faced and had has to be found a solution is overspeeding by bus driving which have resulted in enomours numbers of accidents with negligence of passengers lifes inside the bus. passengers safety and lifes are not given value anymore. and another important factor is overspeeding in humps which have resulted in backbone injuries in high number of passengers
