Vidya Dinker, Naveenchandra to participate in national level consultation on Urban Governance

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jun 16: The class 10 and 12 students of the CICSE board can choose not to appear for pending board exams and be marked as per their performance in pre-board exams or internal assessment, according to top officials.

The board had also submitted the proposal before the Bombay High Court on Monday in response to a petition filed by a parent seeking directions to the authorities to cancel exams in view of the spike in COVID-19 cases.

According to Gerry Arathoon, Chief Executive and Secretary, Council for the Indian School Certificate Examinations (CISCE), the students will have to communicate their option to their respective schools by June 22.

The exams which were postponed due to the lockdown to contain the spread of coronavirus, are now scheduled to be conducted from July 1 to 14. However, several parents have been demanding the exams be scrapped.

"The students will be given two options---they either appear for the rescheduled exams or choose to have their results based on their performance in the pre-board exams or internal assessment. The option will be available only for the pending exams, the result of the subjects for which exams were already conducted, will be calculated as per performance in the exam only," Arathoon said.

The board also clarified that the students will not be entitled to make a subject-wise choice between the two options for pending exams.

Unlike the Central Board of Secondary Education (CBSE), which will only be conducting exams in 29 subjects crucial for promotion and admission to higher educational institutions, the CISCE will be conducting all pending exams.

The pending CBSE exams are scheduled from July 1 to 15. The schedule for the board exams has been decided in order to ensure that they are completed before competitive examinations. While the engineering entrance exam JEE-Mains is scheduled to be held from July 18 to 23, the medical entrance exam NEET is scheduled for July 26.

While the CBSE has given the option to not appear for pending board exams for differently-abled students, it has canceled the examinations for its around 250 schools situated abroad and has adopted the criteria of awarding marks on the basis of either practical exams conducted or the internal assessment marks.

A group of parents has filed a petition in the Supreme Court seeking a direction to the CBSE to declare results on the basis of tests already conducted, and calculate the total on an average basis with internal assessment marks of the remaining subjects.

Universities and schools across the country have been shut since March 16, when the Centre announced a countrywide classroom shut down as part of measures to contain the COVID-19 outbreak. A nationwide lockdown was announced on March 24, which came into effect the next day.

While the government has eased several restrictions, schools and colleges continue to remain closed.

According to Home Ministry guidelines, there will be no exam centres in containment zones.

"Wearing of face masks by teachers, staff and students will be mandatory. There shall be provisions of thermal screening and sanitiser at the centres and social distancing rules will have to be followed at exam centres. Special buses may be arranged by states and UTs for transportation of students to exam centres," the Home Ministry has said.

Davangere, Jan 15: Karnataka Chief Minister B S Yediyurappa on January 14 threatened to resign when the seer of 'Panchamasali Guru Peetha' warned that the community will leave him, if a BJP MLA from the community is not made the minister during the upcoming cabinet expansion.

The chief minister, who is awaiting the BJP high command's nod to expand his cabinet, amid intense lobbying by the aspirants, wanted the seer Vachanananda swamiji and the 'Panchamasali' community to understand his "situation." Yediyurappa pointed out that he has come to power because of the Congress-JD(S) legislators who rebelled against the then coalition government.

The incident took place when Vachanananda swamiji, while addressing an event at Harihara, near here, said "chief minister, you are a good person, Murugesh Nirani (BJP MLA)has helped you a lot, he has stood by you..if you leave his hands this time, the united Panchamasali community will leave your hands." As the swamiji was making this statement, Yediyurappa, who was seated next to him, rose and threatened to leave the stage.

"If you speak like this I will go away...what are you speaking...kindly pardon me, I will leave, you should not speak like this, if you speak like this I can't work..you can give me suggestions, you cannot threaten me," he said, as the swamiji tried to convince Yediyurappa and asked him to take his seat.

As Yediyurappa acceded to his request, the seer said he was not threatening him but was putting forward the rights of the community. The chief minister, who was visibly upset, was seen talking to Home minister Basavaraj Bommai next to him, who even tried to convince the seer not to continue with the topic. Nirani, a MLA from Bilgi who was Industries minister in the previous Yediyurappa government, was seated on the stage when the incident occurred.

Later addressing the event, Yediyurappa said he was not "selfish" and was even ready to resign.

"Vachanananda swamiji has spoken, through you I request him to understand my situation also. If 17 legislators (Congress-JDS), few even as ministers, had not resigned and stayed away, Yediyurappa could not have occupied this Chief Minister position.

You (swamiji) need not make people raise their hands on any demand, if you tell me, I'm ready to listen to you," he said.

Stating that he was ready to take suggestions from the swamiji on all issues, including on how to run the administration for the next 3 years, Yediyurappa said "I'm ready to bow my head and listen to it, if you don't want I'm even ready to resign and go home, I'm not someone who wants to stick to the chair."

Further noting that if he says that the financial condition of the state is not good it will become headline in papers tomorrow, he said he will have to wait till March for the situation to improve.

"I dont have selfishness, I'm aware that if the Panchamasali-Lingayat community had not stood by me, I could have not sat on this chair (CM)... but kindly understand my situation also," he added.

Yediyurappa is expected to expand his ministry later this month after discussing with BJP national president Amit Shah during his visit to the state on January 18.

As the chief minister has already made it clear that 11 of the disqualified JDS-Congress MLAs who got re-elected in the bypolls on BJP tickets will be made ministers, lobbying has been on within the party for the remaining ministerial berths.

Currently there are 18 Ministers, including the chief minister in the cabinet that has a sanctioned strength of 34.

The cabinet expansion will not be an easy task for the chief minister as he will have to strike a balance by accommodating the victorious disqualified legislators as promised and also make place for the old guard, upset at being "neglected" in the first round of the induction exercise.

He also has to give adequate representation to various castes and regions in his cabinet and also deal with allocation of key portfolios.
