I cannot tell you what Hadiya told me: NCW chairperson

Bengaluru, July 25:  Karnataka reported 5,072 new COVID-19 positive cases and 72 deaths on Saturday, taking the total number of cases in the state to 90,942.

The total count includes 55,388 active cases and 1,796 deaths, the state health department said.

Meanwhile, a 100-year-old woman resident of Huvina Hadagali town in Bellary district here recovered from COVID-19 after testing positive for the virus earlier this month.

"Doctors treated me well. Along with regular food, I was eating an apple a day. The doctors are giving me tablets and injection, and I am healthy now. COVID-19 is like a common cold," said Hallamma while speaking to news agency.

The woman's son, daughter-in-law, and grandson had also tested positive for the virus, and the family was treated at their home.

India reported a spike of 48,916 coronavirus cases on Saturday, taking the total number of reported COVID-19 cases to 13,36,861, according to the Union Ministry of Health and Family Welfare.

The total count include 4,56,071 active cases, 8,49,431 cured/discharged/migrated. With 757 deaths in the last 24 hours, the cumulative toll reached 31,358.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Feb 28: The Liquefied Petroleum Gas penetration in Karnataka is 'absolutely 100 per cent' due to the Prime Minister Ujjwala Yojana, Indian Oil Corporation Karnataka Executive Director D L Pramodh said here on Friday.

In 2014, LPG penetration in the State was only 68 per cent, but after the PMUY, massive number of gas connections were given in the last five years, he said, adding, "It is absolutely 100 per cent today."

"There are 1.6 crore LPG connections out of which around 31.5 lakh -- or around 20 per cent -- come under the PMUY. The 100 per cent LPG penetration in the state will help women in rural areas to make their kitchens smokeless. Against the national average of 2.88 cylinders per family per PMUY annually, the figure is Karnataka 3.4 cylinders in Karnataka," Pramodh told reporters.

On the initiative of blending ethanol with petrol, he said it's 8.6 per cent in Karnataka, the highest comparedto other states, where it's five per cent to 5.5 per cent. The state aims to increase it to 10 per cent. By March 31, the IOC would commission the Rs 10 crore Vapour Recovery System at the Devanagonthi terminal on the city outskirts which would ensure that vapour does not go out in the air when tankers are being filled with fuel. "This is an important measure taken tominimise pollution", he said.

Pramodh also said the IOC has started mobile fuel dispensers, delivering fuels at the doorsteps.

Regarding the IOC's preparedness for Electric Vehicle charging stations, Pramodh said the Ministry of Power has given the company a target to set up 500 charging stations across India in the first phase. The IOC has already signed MoUs with NTPC, Power Grid Corporation Limited, Hyundai Motors, Tech Mahindra and Tata Power in this regard.

In Karnataka, 58 sites have been identified for setting up charging and battery swapping stations.

"Total electric vehicle charging facilities planned by IOC in Karnataka by March 31 is 34, out of which 26 will be EVcharging sites and eight battery swapping stations," Pramodh said.
