Shivamogga, Jun 8: Tyavarekoppa Tiger and Lion Safari in Shivamogga re-opened on Monday at 9 am.

Zoo authorities said that they are ensuring that all standard operating procedures are being followed, including ensuring social distancing and wearing of masks by visitors.

It is being ensured that pairs of birds are being kept inside enclosures.

Regular sweeping and spraying on the premises are also being taken care of, authorities said.

Floor markings have been made at the ticket counter to maintain social distancing.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 7: In an attempt to promote menstrual hygiene among women, the Karnataka State Road Transport Corporation (KSRTC) has installed vending machines and incinerators to dispense and dispose off sanitary napkins at 10 bus stands of the state including Mangaluru.

The machines have been installed inside the women's washroom and women can purchase sanitary napkins from the vending machines by inserting five rupee coins.

Nearly 100 napkins can be stored in the vending machines at a time and housekeeping personnel have been instructed to replenish the stock, as and when required.

While directions on how to use the machine have been displayed near the machines, people can get seek assistance from housekeeping staff if needed.

Initially, the machines were installed at two depots in Bengaluru on a pilot basis and in the second phase it has been extended to 10 KSRTC bus depots.
