Bengaluru, Mar 6: School children in Karnataka will have 'bag-free' days on two Saturdays in a month as part of efforts to create a joyful learning experience, Chief Minister B S Yediyurappa announced on Thursday. By making two Saturdays in a month as bag-free days, "Sambhrama Shanivara" will be observed with the objective of creating a joyful learning experience by reducing the burden of text books, he said, presenting the 2020-21 budget in the state assembly.

"The main purpose of such days is to create awareness, by means of activities, on topics that are necessary for students to be ideal citizens," he added.

He also said for the first time in the history of the state his government presented a "child budget", making it a special feature of the budget.

All the policies and programmes for the development of children below the age of 18 are consolidated and presented in this budget and as many as 279 programmes involving Rs.36,340crore, which is 15.28 per cent of the total volume of the Budget, have been earmarked.

English medium of instruction would be given along with Urdu in 400 government Urdu schools and Rs one crore will be provided during 2020-21 for this purpose, Mr Yediyurappa said.

For the education of children of auto drivers, up to Rs 2,000 would be provided annually to each family. For this purpose, Rs 40 crore will be provided in the coming fiscal, the Chief Minister added.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Apr 25: KPCC president D K Shivakumar, has alleged that BJP leaders from the state have sold rice that was meant to be distributed to the poor in Tamil Nadu.

Speaking to newsmen here on Friday, he stated that Congress fully supports the government’s work in the prevention of the spread of COVID-19, but maybe unknown to the Chief Minister, corrupt dealings are which we want to bring to his attention.

He alleged that 1,879 quintals of rice brought from Haryana have been illegally sold to a businessman in Hosur, Tamil Nadu.
