Major credit for Army's surgical strike goes to PM Modi: Parrikar

The Himachal Pradesh police have confirmed the arrested a man for injuring a pregnant cow by feeding her wheat flour ball laced with firecrackers. 

The cow’s jaw was blown off-- reprising the tragic story of a pregnant elephant that lost its life after eating a pineapple stuffed with a firecracker in Kerala.

While the incident took place on May 26 in Jhandutta area of Himachal Pradesh’s Bilaspur district, it came to light only on Saturday, May 6, when the cow’s owner, Gurdayal Singh, uploaded a video of the injured animal on social media.

In the video, Gurdiyal Singh describes how the cow’s mouth had been injured after one Nandlal fed her explosives.

He confirmed that Nandlal works as a mechanic in Singh’s neighbourhood. Singh said that Nandlal has no remorse for his action. Nandlal has said that he is not scared of the repercussions and that he will continue to do whatever he deems fit. “Even the village sarpanch cannot harm me”, challenged Nandlal when confronted by Singh. 

The cow has given birth to a healthy calf since but Singh said the animal is still not able to eat because of an injured jaw and is being administered Glucose.

The video went viral with people demanding strict action against the person who fed firecrackers to the animal.

The practice of studding dough balls with firecrackers isn’t uncommon in Himachal, and farmers resort to this to keep wild animals, especially boards, off their fields. In the Kerala incident too, the explosive-filled-fruit was meant for wild boars. In many parts of the country, including Himachal, the method is also used to hunt for bush meat -- an illegal practice.

Bilaspur superintendent of oolice (SP) Devakar Sharma confirmed the incident and said the cow was fed a highly explosive firecracker popularly called “aalu bomb”. 

Aalu is Hindi for potato. He said a case under Section 286 of the Prevention of Cruelty to Animals Act has been registered and the role of the neighbours named by Singh is being investigated.

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
