EVMs are well guarded and kept safely, claims Karnataka CEO

Mangaluru, Mar 23: The magisterial enquiry into the police firing during the anti-CAA protest on December 19 in Mangaluru, has been postponed following the lockdown of Dakshina Kannada district, Udupi DC G Jagadeesh announced on Monday.

The inquiry by Udupi DC G Jagadeesh was scheduled on Monday. Already, City Police Commissioner Dr P S Harsha and others have deposed before the magistrate. The Deputy Commissioner and the Assistant Commissioner were supposed to appear before the magistrate.

Following the December 19 violence and the death of  Nausheen and Jaleel due to alleged police firing, the state government had commissioned two probes-- one magisterial and the other, a CID inquiry.

 As per the government order, a report on the inquiry was to be submitted before March 23. On the request by the magistrate for more time since the documents and videos had to be examined, the government had asked him to submit the report by April 23.  
 

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Apr 26: After directions from Karnataka government, migrant labourers are being sent to their native villages in batches by hiring as many as 60 buses.

Divisional Controller of Mangaluru KSRTC Division S N Arun said on Sunday that 100 buses from Mangaluru and Puttur ferried stranded labourers on Saturday. Buses were disinfected before the journey.

Buses also left from Dharmasthala, Bantwal, Puttur and Sullia to different destinations. In adherence to social distancing rules, each bus left with 20 to 22 labourers.
