His body cut into 2, man makes organ donation wish

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bidar, Feb 15: Leader of the Opposition in the Assembly Siddaramaiah on Friday demanded the State government to withdraw the sedition case against a mother and a teacher of Shaheen school immediately.

“The police can’t execute anything without the government’s permission. The sedition case against two women should be withdrawn immediately. I will raise the matter in the Assembly to draw the government’s attention,” Siddaramaiah told reporters after meeting the woman at the prison here. 

He clarified that he visited the woman not to support the school, but to extend moral support to her.

“I am an advocate and I can clearly establish based on my experience that staging a satirical play doesn’t amount for sedition. It doesn’t even defame anybody. Three cases of sedition have been registered across the state,” he charged.

He alleged that the government was following dual policy. Though the Supreme Court had concluded that the demolition of Babri Masjid was illegal, a play dealing with the demolition was staged at Kalladka Prabhakar Bhat’s school.
The sedition case had not been registered for staging the play.

He charged that there was an undeclared emergency in the country as the freedom of expression was being suppressed.

Mumbai, May 30: Former Bollywood actress Zaira Wasim has deleted her Twitter and Instagram accounts after being heavily trolled for quoting from the Quran while talking about locust attacks.

"So We sent upon them the flood and locusts and lice and frogs and blood: Signs openly self explained: but they were steeped in arrogance -- a people given to sin. --Qur'an 7:133," Zaira had tweeted.

Soon, she started receiving hateful comments from netizens who interpreted her post as a justification of the locust attacks. They felt that Zaira was suggesting that the incident is God's way of expressing wrath.

Shortly after being deluged with such comments, Zaira Wasim deleted her Twitter and Instagram accounts.

However, a section of netizens continue to attack Zaira on her Facebook page, where she put up the same post.

Commenting on the post, a user wrote: "Lady you must have taken into account of those people of JK, Kerala and elsewhere who are also suffering from the virus. Moreover the crops which are damaged by locust had no name as to who will consume them. In this hours of crisis please post something which is positive and reflects your education."

Another user shared: "So according to you, with all due respect every year on the same time period, Allah send locust to India to destroy the crops of poor farmers who are not even involve in the industrial rise, who don't use vehicle to destroy the nature, and Allah send locust only to harm the poor farmers and not the rich one who actually destroy nature."

"So those farmers who lost there fields of crops and will probably go into debt and may also commit suicide, those farmers who feed the nation, who feed you and every one, are sinners?" asked yet another user.

However, there were a few on social media who felt Zaira had done nothing wrong.

"Quoting Quranic Verse is not a crime... Why is every Indian abusing @ZairaWasimmm. She didn't mention any particular nation or religion. I request everyone please stand with #ZairaWasim. She needs our support. #ISupportZairaWasim," goes a tweet.
