Karnataka CM fumes over shifting of Aero India show out of Bengaluru, seeks answer from BJP

Bengaluru, Jul 10: Former Karnataka Chief Minister and Congress leader Siddaramaiah on Thursday condemned the decision of the HRD Ministry to drop chapters on citizenship, secularism and federalism from Class 11 political science syllabus, stating that this will "deprive a generation of students from understanding the important pillars of Indian democracy".

"I strongly condemn the decision of @HRDMinistry to drop chapters on citizenship, secularism and federalism. This will deprive a generation of students from understanding the important pillars of Indian democracy. #Stop Saffronisation Of Education," Siddaramaiah tweeted.

The Congress leader further alleged that BJP does not believe in the principles of citizenship, secularism and federalism.

"Chapters on citizenship, secularism and federalism are dropped from Class 11 Pol Science. syllabus. Does this explain something? Yes, it explains that @BJP4India doesn't believe in these principles and validates its past behaviour," he said in another tweet.

Earlier in the day, Union Human Resource Development (HRD) Minister Ramesh Pokhriyal Nishank rejected criticism over alleged conspiracy in CBSE's decision to reduce the syllabus of schools due to COVID-19 outbreak and urged the critics to "leave politics out of education".

"There has been a lot of uninformed commentary on the exclusion of some topics from #CBSESyllabus. The problem with these comments is that they resort to sensationalism by connecting topics selectively to portray a false narrative," the Union Minister tweeted.

"It is our humble request:#Education is our sacred duty towards our children. Let us leave politics out of education and make our politics more educated," he added.

The CBSE has revised the syllabus for the classes IX to XII during the academic session 2020-21 in the wake of the situation created by COVID-19.

In a circular issued to all the heads of the institutions affiliated to it, the CBSE had said that the revision of syllabi has been done due to the extraordinary situation prevailing in the country and different parts of the world.

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, Mar 23: Indian Coast Guard (ICG) on Monday announced to enhance surveillance along the coastline of Karnataka to strengthen security.

It has tasked its hovercraft in New Mangalore, and high-speed patrol vessels and interceptor boats along the coastline for ensuring foolproof security of the uninhabited islands, Deputy Inspector General S B Venkatesh, Commander, Coast Guard, Karnataka, said in a release today.

The amphibious hovercraft have been deployed for near to coast patrol, to facilitate smooth execution of search and rescue operations and security cover over land and riverine route. Please log in to get detailed story.
