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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Mangaluru, Feb 18: Notorious serial killer 'Cyanide' Mohan has been sentenced to life imprisonment by a court here for the murder of a 23-year old woman from Kasaragod district of Kerala in 2006.

That was the 19th of the 20 murder cases slapped against him.

Sixth additional district and sessions court judge Sayeedunnisa  said the life sentence will commence after he serves the sentence of imprisonment in the other cases.

Cyanide Mohan had 20 murder cases registered against him. He is accused of killed several women using cyanide after befriending and raping them.

He has been awarded the death sentence in five cases and life imprisonment in three. Two of the death penalties were later commuted to life imprisonment.

According to the charge sheet in the latest case, Mohan met the woman while she was going to work at a unit of CAMPCO here. After befriending and offering to marry her, on January 3 in 2006, he took her to Mysuru and stayed in a lodge near the bus stand.

Like in all other cases, the next morning, Mohan asked the woman to remove her ornaments. The two went to the KSRTC bus stand where he asked her to consume a pill convincing her that it was a contraceptive. However, it was laced with cyanide.

The woman, who consumed the pill in the washroom, collapsed and was declared brought dead at a hospital.

As in previous cases, Mohan went back to the lodge and left the place along with her ornaments.

He was arrested later from Bantwal in 2009, after which he admitted to killing 20 women.

The judge directed the District Legal Service Authority to take steps to award compensation to the woman's mother under the Karnataka victim compensation scheme.

Bengaluru, Jun 30: In an attempt to tackle unemployment amidst covid-19 crisis, the Karnataka state government has launched a job portal connecting employers and job seekers.

The portal, 'Skill connect' ( https://skillconnect.kaushalkar.com/ ) provides region-wise and sector-wise job listings. An interested candidate can register on the portal and either apply for jobs or can also seek skill training. 

As on Monday, the portal has 25 registered companies with over 2000 jobs available in various sectors. 

The portal works more or less on similar lines as that of any private job portal, except that those posting jobs and candidates searching for employment will have to register with the Skill Development Department. 

Launching the portal on Monday, Chief Minister BS Yediyurappa hoped that the portal would provide an impetus to job creation, as well as the economic revival of the state. 

Deputy Chief Minister Dr. C.N. Ashwath Narayan who is also the skill development Minister added, "All these years, there was no information and communication between job seekers and recruiters. This portal will solve that problem."

Also, until now, there hasn't been comprehensive information either on those seeking jobs or those looking for employees. The skill development efforts have not been in sync with the market. All these issues would be addressed by the portal, he said. 

According to Karnataka Skill Development Authority Managing Director Ashwin Gowda, the portal has already seen a response with about 68 applicants in just a day. 

Officials said even the organisations will have to register with the government while providing all documents concerned. The government aims to avoid any fake job advertisements through this. "We will also enable virtual interviews between the candidate and the employer," sources in the department told DH. 

Recently, the government had also launched a portal exclusively for migrants who had returned to Karnataka from other places. This was meant to work as a skill registry.

However, the portal that was launched on Monday, went a step ahead by connecting both the prospective employers and employees, according to officials in the department.
