Let them eat beef at home and die: Yeddyurappa

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

New Delhi, Feb 1: The budget is a little more demanding of the non-resident Indian. Firstly, to be categorized a non-resident, an Indian now has to stay abroad for 240 days, against 182 previously. In other words, an Indian national, to claim the non-resident status, can’t stay in India for 120 days or more in a year.

“We've made changes in Income Tax Act where if an Indian citizen stays out of the country for more than 182 days, he becomes non-resident,” said Revenue Secy Ajay Bhushan Pandey. “Now in order to become non-resident, he has to stay out of the country for 240 days.”

The second rule is more deadly: a non-resident Indian, who is not taxed in the foreign country, will become taxable in India.

“If any Indian citizen is not a resident of any country in the world, he'll be deemed to be a resident of India and his worldwide income will be taxed,” said Pandey.

"It's a very big disadvantage for Indians residing overseas only to save on tax,"  said Dinesh Kanabar of Dhruva Advisors. He expects that many Indians stay abroad in countries, where the income tax is low or nil such as Dubai. Now they will be taxed in India if they are in the income tax bracket.

For Indians, finance minister Nirmala Sitharaman revised income tax rats and proposed new tax slabs.

The new income tax rates will, however, not allow exemptions under Section 80C. Home loan exemption, insurance exemptions, the standard deduction will also not stay under the regime.

"The new tax regime will be optional and the taxpayers will be given the choice to either remain in the old regime with exemptions and deductions or opt for the new reduced tax rate without those exemptions," Sitharaman said while unveiling Budget.

Mangaluru, Jan 22: Eminent industrialist Dr Mohammed Yusuf has been elected the chairperson of the Karnataka State Board of Auqaf. 

10 members of the Board cast their votes in the election held to the top post today at its office in the city. While Dr Yusuf, who was backed by the Congress, secured six votes, K N M Shafi Sa’adi, who was backed by the BJP, secured only 4 votes.

Addressing reporters, Dr Yusuf said that there was 1.32 lakh acres of Wakf land at the time of Independence. A large number of the properties were lost under various laws, including the Inam Land Abolition Act.

Flanked by Congress MLA Tanveer Sait and Minorities Welfare Dept secretary A B Ibrahim, Dr Yusuf vowed to strive hard to make the Board an example for the entire country. 

74-year-old Dr Yusuf had held the post more than once in the past. A veterinarian, Dr Yusuf had quit the government job and set up business in Bengaluru and Dubai decades ago and has earned considerable success.
