DKMA hands over Rs 2 lakh to Ullal attack victim's kin

Bengaluru, Apr 1: The Opposition Congress leader in the Karnataka Assembly, and former Chief Minister Siddaramaiah has appealed the party legislators and MPs to contribute a minimum rupees one lakh each, towards the KPCC's Corona relief fund.

In a statement, here on Tuesday, Siddaramaiah had stated that the COVID-19 disease had created a havoc among the people of the state, and had thrown thousands of people jobless and struggling to get access to the food grains as well as to medical aid.

The people of the state, who had battered from the unprecedented rains and floods recently, had to face another daunting challenge of the spread of COVID-19 virus across the state.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Mar 16: A 23-year-old mobile app developer was arrested on Saturday for allegedly forging the signature of Infosys Foundation chairperson Sudha Murty to rope in Telugu actor Vijay Devarakonda as an app’s ambassador.

The arrest of Laveti Sai Krishna alias Krishna ML, a resident of Hyderabad, comes a year after the case was registered. Jayanagar police registered a case against Krishna on February 26, 2019 based on a complaint filed by Lt Col (retd) M Ramesh, representative of Infosys Foundation. The complaint was filed after the forged letter didn’t reach Devarakonda and came back to Infosys Foundation instead.

App developer is a B.Pharma holder

“We conducted an investigation and traced the app designer. We caught him and based on information provided by him, we learnt that Krishna was the brain behind the forged signature,” a senior police officer said.

Krishna confessed that he developed a mobile app — ‘Offer nearby’ — and planned to launch it in a big way. He wanted Telugu actor Vijay Devarakonda to be the app’s brand ambassador and tried contacting him. Krishna, however, was unable to meet Vijay.

Krishna then thought he could easily reach the actor if he sent a recommendation letter in the name of Sudha Murty.

“He forged the letterhead of Infosys Foundation and Sudha Murty’s signature. We are verifying his antecedents to know if he committed any other offence earlier,” said Rohini Sepat-Katoch, DCP (south). Rohini said Krishna is a B.Pharma holder and worked with an advertisement firm. Later, he planned to develop an app that provides details of offers for retail customers. He floated Laveti Technologies, and with help from a friend, developed ‘Offer nearby’.

As per the complaint, Krishna created a fake letterhead in the name of Sudha Murty and wrote to Devarakonda, asking him to become the brand ambassador/ partner for his mobile app. Krishna sent it through SpeedPost mentioning the sender’s address as Infosys Foundation. Krishna’s game was up when the letter, which wasn’t delivered to Devarakonda, came back to Infosys Foundation.
