‘Entire world should embrace Islam’: Out-of-context clip of Om Puri goes viral

Shivamogga, Jun 20: Shivamogga District unit of Congress led by party veteran Kagodu Thimmappa staged a protest against state government's proposal to amend the land reform act, which will allow non-agriculturist to buy farmland.

The leaders of Farmers' Union (Raith Sangh) also staged a protest at Mahaveer circle and questioned CM's stand as he took oath in the name of farmers.

The district congress staged a protest at the premise of the Deputy Commissioner office in Shivamogga city.

The protesters termed Karnataka Government led by Chief Minister BS Yediyurappa as an anti-farmers government.

According to Congress and Raith Sang, the proposed amendments to Karnataka State Land reforms act 1961 will cause harm to farmers.

"According to the proposed amendment, non-agriculturists like business tycoons can also purchase the agriculture land. This will help the businessman and will be harmful to farmers," protesters said.

Mysuru, Mar 7: Karnataka Minister for Medical Education K Sudhakar on Saturday said that State Government may consider suspending the touch-based Biometric time and Attendance system for its employees in view of the COVID-19 threat.

Speaking to media persons while inspecting the medical infrastructure at KR Hospital here on Saturday, he said that many IT companies have already suspended the Biometric Attendance system in a bid to prevent the spread of the virus. Given the threat perception, the government was also contemplating the same and would consider it. However, he did not specify the date.

With regard to the preparedness to handle the threat, the Minister said the government was extremely cautious since last 20 days and had taken all precautionary measures. “All international passengers at the airport are being screened and so far nearly 1 lakh passengers have been screened and anyone with symptoms will be quarantined for 28 days.’’

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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