BJP controlling a section of media; playing negative politics: Gundu Rao

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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, Jul 8: In a setback to the State government, the Karnataka High Court on Wednesday stayed the initial ban and the subsequent restrictions imposed on schools against conducting online classes from pre-primary to Class X.

Prima facie the ban and embargo imposed on online education violate Articles 21 and 21A of the Constitutionon the fundamental right to education, the Court said.

A Division Bench comprising Chief Justice Abhay Shreeniwas Oka and Justice Nataraj Rangaswamy passed the interim order staying the operation of Government Orders issued on June 15 and June 27 respectively.

The Bench passed the interim order on the petitions filed by parents of children and several educational institutions questioning the legality of the ban and the restrictions imposed.

However, the Bench made it clear that this order should not be construed that the schools have right to make online education compulsory and can charge fee for offering online education. Also, the schools should not deprive students, who cannot opt for online education, the lost education when the schools reopen on regular basis.

Bhopal, Mar 18: Congress leader Digvijay Singh's detention by police in Bengaluru is display of "dictatorship and Hitlarshahi" by the BJP, Madhya Pradesh Chief Minister Kamal Nath said here on Wednesday.

Singh staged a protest near a Bengaluru resort this morning where rebel MLAs of Madhya Pradesh Congress are staying, and demanded that he be allowed to meet them.

Singh, who has been detained by the police, accused the BJP of holding the MLAs captive and said that he would go on a "hunger strike".

Reacting to this, Nath said if the need arises he would also go to the Karnataka capital.

"Preventing Congress Rajya Sabha candidate and other ministers from meeting MLAs, misbehave with them, forcibly taken them into custody is totally a dictatorship and hitlershahi (sic)," Nath said in a tweet.

"Entire country is watching how an elected government is being made unstable and how BJP is murdering democratic values," Nath said.

"Why they are not allowing them to meet MLAs. What BJP is afraid of. BJP is playing a dirty political game in the state," the chief minister tweeted.

Demanding immediate release of detained Congress leaders, Nath said that democratic norms and Constitutional values are being stifled.

Later speaking to reporters, the CM said, "Why the BJP is afraid of presenting 16 MLAs here (Bhopal)? What is the problem in one person (Singh) meeting with 16 legislators?"

Nath reiterated that his government had proven majority on floor of the House in the last 15 months since coming to power.

Amid political uncertainty in Madhya Pradesh, the state Congress Legislature Party on Tuesday moved the Supreme Court seeking direction to the Centre and the BJP-led Karnataka government to grant it access to communicate with its rebel MLAs staying in Bengaluru.

The apex court had also directed the Kamal Nath government to respond by Wednesday to a plea by senior BJP leader Shivraj Singh Chouhan seeking immediate floor test in the Assembly.
