Bengaluru, Feb 10: Former Karnataka chief minister HD Kumaraswamy's son Nikhil Kumaraswamy today got engaged to Revathi, the grand-niece of Congress leader and realtor M Krishnappa.

On February 6, Mr Nikhil shared a picture with Ms Revathi on his official Facebook account.

Mr Nikhil's grandfather and former prime minister of India HD Deve Gowda attended the event along with several other politicians at the Taj West End.

BJP leaders including Chief Minister B S Yediyurappa former chief minister Jagadish Shetter were also present.

Mr Nikhil, 30, is a Kannada film actor who made his debut in the bilingual movie Jaguar in 2016. The actor will soon start shooting for his new movie Production No-1.

In the 2019 Lok Sabha elections, he lost to Sumalatha Ambareesh, widow of former Karnataka actor Ambareesh, in the Mandya constituency in Karnataka.

Chennai, Feb 5: In order to ensure housing for all, the Madras High Court has proposed ban on non-resident Indians from purchasing houses in India, prohibit speculative sale, and impose 100 per cent extra stamp duty on purchase of second house.

The court on its own impleaded the Union housing and finance ministries as party respondents.

It has directed them to answer a series of questions including as to how many families have basic amenity of housing in India as well as in Tamil Nadu, population and housing ratio in the country and in the state, when 'Housing for All' mission of the central government would be achieved.

"Why the government does not consider imposing such restrictions to control escalation of house prices and to provide a house to every family in the country, a division bench of Justice N Kirubakaran and Justice Abdul Quddhose wondered.

Directing the authorities to inform as to whether the central and state have got special schemes to provide housing for the marginalized and economically weaker sections including SC/ST communities, the bench has also sought the details of the number of families that possess more than one house.

"Why the governments do not restrict families/individuals from purchasing/possessing more than one housing unit/flat/plot till "Housing for all" is achieved?

Why not the government charge 100 per cent more or extra stamp duty to discourage buying more than one house by a family while purchasing second house?

Why not the government conditionally allow the families to purchase more than one house provided the said family pays 100 per cent extra statutory dues like property tax, electricity charges, water and sewerage charges on the second property?" the bench said.

This apart, the court also wanted the authorities to know as to why it should not prohibit the NRIs from purchasing houses in India to bring down the cost of housing.

Justifying its directions, the court said "Lakhs and lakhs of people are living on platforms, roads, and cement pipes, slums, under the trees and on banks of water bodies without proper shelter and basic amenities and safety."

It is true that the Centre had taken a policy decision to provide housing unit to every family.

It should be achieved at the earliest, the court said, adding it could become fruitful when restrictions are put on persons who hold more than one housing units.

The court passed the order while hearing an appeal moved by the Tamil Nadu Housing Board challenging a single judge order against acquisition of about 369 acres of private land in Thudiyalur and Vellakinar areas of Coimbatore for a housing scheme.

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
