Udupi: Bajrang Dal men thrash 2 for transporting buffaloes; arrested

Bengaluru, Jun 16: Former prime minister H D Deve Gowda on Tuesday termed as 'disturbing' the violent clash between Indian and Chinese troops in Galwan Valley and said the government should offer a clearer picture to the nation on the border issue.

He sought to know as to how Indian soldiers lost their lives during a de-escalation process and said Prime Minister Narendra Modi and Defence Minister Rajnath Singh should come out with a clearer picture.

"Reports coming from #GalwanValley are disturbing. Why did our soldiers lose their lives during a de-escalation process? In national interest, the PM and RM should offer a clearer picture to the nation on the border issue with the Chinese. #LADAKHSTANDOFF," Gowda tweeted. An Indian Army officer and two soldiers were killed during the confrontation with Chinese troops in the Galwan Valley in eastern Ladakh on Monday night, the first such incident in the last 45 years that reflected massive escalation in the five- week border row.

The Army said India lost an officer and two soldiers during the violent face-off, while there were casualties on the Chinese side as well.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 17: A private flight chartered by UAE-based NRI hotelier Praveen Shetty has brought home around 175 people from United Arab Emirates.

This is the third flight chartered by Mr Shetty, chairman of the Fortune Group of Hotels, and president of the Karnataka Non-Resident Indian Forum, to repatriate his employees and other stranded Kannadigas.

The Air Arabia flight with 168 adult passengers and six infants on board took off from Sharjah International Airport at 9:45 pm (UAE time) on June 16 and landed at Mangaluru International Airport at 2:50 am Indian Standard Time on June 17.
