Mangaluru: Miscreants attack two innocents with lethal weapons after Katipalla murder

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Bengaluru, Jul 16: Chief Minister B S Yediyurappa led state government’s move to amend the Karnataka Land Reforms Act was “a scam bigger than illegal mining” as farm lands worth Rs 50,000 crore will be lost, according to Leader of the Opposition Siddaramaiah.

The government on July 13 promulgated an ordinance to amend the Karnataka Land Reforms Act, allowing non-agriculturists to buy agricultural lands while also increasing the cap on the extent of such land a person or a family can hold.

Plus, the amendment will have retrospective effect, meaning over 13,000 cases registered over the years for alleged violations in acquiring farm lands will be vacated or dismissed.

“There are 13,814 cases across all 30 districts. Let’s assume that each case involves four acres of land. That’s 52,000 acres. These are lands worth Rs 45,000-50,000 crore,” Siddaramaiah told a news conference. “This is a scam bigger than illegal mining. While the mining scam had specific players, here the entire government has fallen for the corporate bodies and real estate lobby.”

The illegal mining scam unearthed when the BJP was in power was pegged at Rs 35,000 crore, which became a poll plank for the Congress to come to power in 2013.

Calling it a “black” legislation, Siddaramaiah said the amendments to the land reforms law will result in large portions of farm lands becoming real estate. “This will destroy the farming community. They’ll now have to stand at the doors of corporate bodies. Farmers will sell their land and real estate will come. What’ll happen to food production?” he said.

The ordinance amends Section 63 and 80 of the Act, while omitting Sections 79A, B and C. “These sections were inserted in 1974 under the D Devaraj Urs government. It was a revolutionary, progressive step to protect farmers and ensure social justice,” Siddaramaiah said.

The Congress leader claimed that there was a “biggest conspiracy” behind this. “All this is being driven by the Modi government. They want to privatize more and more so that reservations will go. They want to bring back the zamindari system,” he said, citing the examples of some other recent amendments to other laws.

The timing of the ordinance is suspect, he said. “If the Yediyurappa government really wanted to help farmers and had good intentions, they could’ve brought this before the Assembly or placed it for public discussion. Instead, they’ve made use of the lockdown period to promulgate the ordinance,” he said.

The Congress will fight the ordinance till it gets withdrawn, Siddaramaiah said. “We will talk to other parties, farmers organisations and Dalit groups to plan protests against the BJP’s hidden agenda and anti-farmer policies,” he added.

Hubli, April 3: Twelve people including 5 women as well as 50 unidentified people have been booked for allegedly pelting stones at police personnel in Mantur area of Hubli on Friday.

The police were allegedly attacked for stopping people from offering Friday prayers at a mosque, during the ongoing lockdown put in place in the wake of the coronavirus outbreak.

"12 people including five women and 50 unidentified people have been booked for stone-pelting at police personnel in Mantur area of Hubli today. The women have been taken into custody while police are searching for the others," said Hubli-Dharwad Police Commissioner R Dilip.

The Police Commissioner further said, "Some prominent people of the community had also urged the devotees to go to their homes but they got agitated."
