Defeat those who are politicising gods and spoiling harmony: Prakash Raj

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Belagavi, Feb 10: In comments that raised eyebrows, Ramesh Jarkiholi, who quit the Congress and joined the BJP and who took oath as minister last week, said his brother Satish has a bright future. The two siblings have rarely seen eye-to-eye — at least in public — in recent times.

He also trained his gun on Congress leader DK Shivakumar, sarcastically thanking the Congress MLA for his meteoric rise. “Had Shivakumar not stood against me, I would not have emerged as a tall leader in the state. I must thank him,” Ramesh said.

The Gokak MLA said Satish of the Congress, the most politically-savvy of the five Jarkiholi siblings, would reach “the top” in his political career. However, he advised him “to inculcate patience and adopt strategies”. “He should make his moves at the right time as timing is very important in politics,” Ramesh said.

He also urged Satish to keep his supporters happy. “Many of his followers are disappointed with his leadership because he does not extend a helping hand to his own people. In the present political climate, people do not endorse a leader who only talks about Buddha and Basava,” Ramesh said.

Ramesh took a dig at Lakan, the youngest sibling, saying, “Lakan speaks ill about me most of the time. He does not understand much. But we brothers are one when it comes to family. We are united when it comes to family matters, but when it comes to politics, we are at loggerheads.”

Hubli, Mar 9: A Hubli court on Monday rejected the bail application of three Kashmiri students, who were booked for sedition, after their video allegedly raising pro-Pakistan slogans went viral.

The plea was filed under Section 439 of CrPC.

This comes after the Hubli Bar Association earlier withdrew its resolution against representing the three Kashmiri students and said that advocates who wish to appear for them can approach Dharwad Principal District Court to file bail plea.

The three students are Basit Ashik Sophi (19), Talib Majid (19) and Amir Mohiuddin (23). They were booked under sedition charges for raising pro-Pakistan slogan in a video shared on social media.

They were earlier transferred to Belgaum Hindalga jail from Hubli sub-jail and the case, registered in Gokul Road police station, was also transferred to the rural police station because the video was recorded in the college hostel room, which is in its jurisdiction.
