Cops raid slaughterhouse; arrest 3; seize 3 cows, 200kg meat, 3 vehicles

Bengaluru, Feb 4: A 33-year old woman techie allegedly stabbed her mother to death and made a murderous assault on her younger brother before fleeing their home here, police said on Tuesday.

According to police, the woman fatally stabbed her mother using a knife and attacked the brother early on Monday.

The injured brother has been hospitalised here.

A search was on for the techie and the motive for her action under investigation, police said.

The woman, employed as a software engineer with a company here, earlier had told her mother and 30-year old brother that she has been transferred to Hyderabad and she may have to relocate.

The brother told police that in the early morning on Monday he saw his sister searching something desperately and offered to assist, which she refused.

However, minutes later she made a murderous assault on him, he told police, adding when he screamed for help and called his mother, his sister said she has killed their mother.

She stabbed him and attacked with an iron rod before fleeing, her brother told police.

The body of the mother was found in another room in the house.

"We are still investigating the matter. We are not clear about the motive behind the murder," a police officer told media adding the woman was yet to be arrested.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 9: Two grassroots level workers of the Bharatiya Janata Party (BJP) on Tuesday filed their nominations for the Rajya Sabha elections from Karnataka, Chief Minister and senior BJP leader BS Yediyurappa said.

"Eranna Kadadi and Ashok Gasti have filed nominations for the Rajya Sabha elections from Karnataka. It is only in BJP that grassroots level workers are given recognition," Yediyurappa told reporters here.

The elections to fill the vacant 18 Rajya Sabha seats from seven states are scheduled to be held on June 19. Elections to four Rajya Sabha seats will be held in Karnataka.

"The core committee of the party had recommended a few names. Afterwards, the party's all-India president consulted with me. Finally, these two names were finalised," Yediyurappa said.

The nominations will be scrutinised on Wednesday and the last date for withdrawal of nomination is June 12.

Notably, the Janata Dal (Secular) on Monday announced that party supremo and former Prime Minister HD Deve Gowda has decided to contest the forthcoming Rajya Sabha elections.
