Govt to bear Rs 78 cr cost of 108-ft-tall Kempegowda statue outside Airport: DyCM

Mangaluru, Jul 20:  Ananthapadmanabha temple at Kudupu on the outskirts of Mangaluru will be closed for devotees on the occasion of Nagara Panchami on July 25 due to Covid-19.

Ananthapadmanabha temple at Kudupu is one of the famous temples in Dakshina Kannada dedicated to Naga (Serpent God) where Nagara Panchami is celebrated in a grand way.  The temple committee said that "Nagara Panchami will be observed on July 25. To avoid large gatherings, the entry of devotees is banned. The devotees should not visit the temple, thereby extend cooperation with the temple committee."

On the day of Nagara Panchami, no sevas, theertha and prasadam will be distributed. There will be no mass feeding 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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

New Delhi, May 12: Air India is planning to operate 149 repatriation flights to 31 countries between May 16 and May 22 during the second phase of the Vande Bharat mission to bring back home Indians stranded abroad amid the coronavirus-triggered lockdown, officials said. During the first phase of the Vande Bharat mission, Air India and its subsidiary Air India Express are scheduled to operate total 64 flights between May 7 and May 14 to bring approximately 15,000 Indians from 12 countries on a payment basis.

"In the second phase, Air India and Air India Express will operate 149 flights to countries such as the USA, the UAE, Canada, Saudi Arabia, the UK, Malaysia, Oman, Kazakhstan, Australia, Ukraine, Qatar and Indonesia," the airline officials stated.

Other countries to where the national carrier would operate flights between May 16 and May 22 are Russia, Philippines, France, Singapore, Ireland, Kyrgyzstan, Kuwait,

Japan, Georgia, Germany and Tajikistan, officials noted.
The flights during the second phase will also be operated to Bahrain, Armenia, Thailand, Italy, Nepal, Belarus, Nigeria and Bangladesh, they mentioned.

India has been under lockdown since March 25 to curb the spread of the novel coronavirus, which has infected more than 70,000 people and killed around 2,290 people in the country till now. All scheduled commercial passenger flights have been suspended for the lockdown period.
