ACB unearths Rs 70.18 lakh cash staked in Mangaluru house of Udupi RTO officer

Hassan, Feb 2: Former prime minister and JD(S) supremo H D Deve Gowda has said that the controversy over the Citizenship (Amendment) Act should be resolved peacefully through discussion.

Speaking to reporters in Halebeed on Saturday, Gowda said that the Act affects only Muslims but would also prove troublesome for the Hindus. “Opening fire on anti-CAA protesters is the not solution to the issue,” he said.

Deve Gowda said that during his tenure as prime minister a number of problems concerning Muslims were addressed. “But, in the run up to election, Rahul Gandhi described us ‘B’ team of BJP. This led to vote swing,” he added. When his comment was sought on the budget, the former prime minister said that he had not yet read the budget document.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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 21: The total number of Covid-19 cases in Karnataka breached the 70,000 mark on Tuesday as the state reported 3,649 fresh infections, while 61 fatalities took the death toll to 1,464, the health department said.

Twenty-two out of 61 deaths reported on Tuesday are from Bengaluru urban, followed by five each from Dakshina Kannada, Mysuru and Dharwad, four each from Kolar and Belagavi, three each from Hassan, Tumakuru and Haveri, Bidar 2, and one each from Chikkaballapura, Chikkamagaluru, Chamarajanagara, Gadag and Vijayapura.

Most of the deceased either had a history of Severe Acute Respiratory Infection (SARI) or Influenza-like illness (ILI). Out of 3,649 cases tested positive on Tuesday, contacts of the large number of the cases are still under tracing.

Among the districts where new cases were reported, Bengaluru urban accounted for 1,714, Ballari 193, Dakshina Kannada 149, Mysuru 135, Yadgir 117, Uttara Kannada 109, Hassan 107, Kolar 103, followed by others.

Bengaluru urban district topped the list of positive cases, with 34,943 infections, followed by Dakshina Kannada 3,829 and Kalaburagi 2,966. Among discharges Bengaluru urban was on top with 7,476 discharges, followed by Kalabuagi 1,834 and Udupi 1,731.

A total of 10,64,734 samples were tested so far, out of which 43,904 were tested on Tuesday alone, the bulletin said. It said that 19,328 of the 43,904 samples tested today were rapid antigen tests.
