Fishermen offer Samudra puja' in Mangalore

Bengaluru, Mar 3: Chief minister BS Yediyurappa on Monday introduced the Karnataka Municipalities and Certain Other Law (Amendment) Bill, 2020, in the assembly to give voters the opportunity to reject candidates in civic polls.

The bill, if passed, will enable election officials to offer the NOTA option in the elections to municipal corporations on the lines of assembly and Lok Sabha polls.

An amendment bill which seeks to enable the government to set up a separate university for the districts of Raichur and Yadgir was also tabled. The government said the workload of Gulbarga University necessitated creation of a separate university for the two districts, a move that will also help reduce regional imbalance in Kalyana Karnataka region.

Another amendment bill seeks to allow industrial units, which have failed to start operations on allotted land after seven years, to sell off the parcels to another unit. Bills which empower authorised agencies to regulate turf clubs and horse racing and regulate salary and pension of teachers in higher education institutions were also introduced in the assembly on Monday.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Thiruvananthapuram, Feb 21: A school in the city has allegedly denied admission to a boy whose parents did not fill the religion column in the application form, prompting the Kerala education department to seek a report.

The parents, Naseem and Dhayna, had sought admission for their son to the first standard at the St Mary's school, a government-aided institution. They alleged that school authorities had claimed that registration will not be possible on the education department's 'Sampoorna' portal without filling the 'religion' column.

"We were informed by the school authorities that it was not possible to give admission to our child as we wrote 'nil' in the religion column. They claimed that if nil is mentioned, the admission process will not get registered in the school management software of the education department," Naseem said.

Sampoorna is a school management system project implemented by the Kerala education department to automate the system and process of over 15,000 schools in the state.

The parents later approached the ministry and the Directorate of Public Instruction (DPI) to get further clarification.

"The state government officials denied that there were any issues with the software and confirmed to us that the admission process was going on.

When we approached the school authorities again, they asked us to give in writing that we, the parents will take responsibility of any issues that may occur in the future," Naseem said.

The parents then decided not to enroll their son at the school due to the manner in which the issue was handled by the institution. Reacting swiftly, the state government sought a report from the DPI and the deputy director of the education department on the matter.

"We have asked the DPI and the deputy director of the education department to look into the matter and file a report as soon as possible," Education minister C Raveendranath told PTI. The parents said after the news spread, a school official called them offering admission.

"But we decided not to enroll him there due to the approach of the school authorities," he said.

Naseem runs a catering business after returning from the Gulf.

The school management in a release claimed that they sought a letter in writing from the parents to avoid trouble in the future. "When school authorities asked why the religion column was left blank, the parents said they were not interested in filling that part. The parents have that right.

But most benefits given by the government to school children are based on religion. We just wanted to ensure that the parents take the responsibility in case the student misses out any such benefits in the future," the management said.

School authorities maintained they never denied admission to any student. The parents are now looking for admission for their son in other schools in Thiruvanathapuram.

Ravindranath recently claimed in the state Assembly that over one lakh children in Kerala had left columns relating to caste and religion blank in school admission records during the 2017-18 academic year. In a written reply, he said as many as 1,24,147 children had not filled these columns while enrolling in different classes in government and government-aided schools during the period.
