Mangaluru: SSF holds jihad against terrorism' awareness rallies

Mangaluru, Jan 31: The Pumpwell flyover, part of the four-laning of Talapady-Kundapura stretch of National Highway 66, was finally inaugurated today.

Work on four-laning NH 66 between Talapady-Kundapur, excluding the Nanthoor-NITK Surathkal stretch, started in September 2010 and Pumpwell (Mahaveera Circle) flyover was a part of the project. Concessionnaire M/s Navayuga Udupi Tollway Pvt., Ltd., failed to execute many flyovers on the stretch within the prescribed time, including Thokkottu and Pumpwell in Mangaluru, Karavali Circle in Udupi, and Shasri Circle in Kundapur.

Thokkottu and Karavali Circle flyovers are complete now while Shastri Circle flyover as well as the four-lane road within Kundapur town are still incomplete. Similarly, a small bridge and portion of the road in Padubidri too is yet to be completed.

District in-charge minister Kota Srinivas Pojjary and MP Nalin Kumar Kateel inaugurated the long-pending Flyover

MLA Vedavayas Kamath, MLA Bharath Shetty were also present on the occasion.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mandya, Apr 7: A man who was suspected of having the COVID-19 infection, escaped from the isolation ward of the Mandya Institute of Medical Sciences (MIMS), on Monday, creating panic among the people and hospital staff.

The man had earlier been in quarantine in Malavalli. On Sunday night He was shifted to MIMS Hospital, after he complained of throat infection and breathing problems and was kept in an isolation ward.

On Monday morning, however, the hospital staff found missing from the ward. They immediately reported the matter and launched a search for him. Superintendent of Police K Parashuram and Additional SP V J Shobharani and others rushed to the spot and began an inquiry. They also viewed the CCTV footage.
