Bengaluru/Ballari, Jan 7: Former minister BZ Zameer Ahmed Khan of the Congress set a one-week deadline for the BJP government on Monday to arrest Ballari City BJP legislator G Somashekhara Reddy for his recent speech warning Muslims of dire consequences if they continue to protest against the Citizenship (Amendment) Act.

Police have already booked Reddy, younger brother of tainted mining baron G Janardhan Reddy, under section 153-A (promoting enmity between different groups on grounds of religion) of the Indian Penal Code.

However, Khan took the fight to Reddy a step further. “If the government fails to arrest Reddy by January 13, I will stage a dharna outside his house in Ballari, come what may. Let them do whatever they want,” Khan told reporters in Bengaluru.

In his speech at a pro-CAA rally organized by BJP workers and ABVP activists in Ballari, the BJP legislator had said, “We [Hindus] are 83% and they [Muslims] are 17% and if we take law into hands, you know what will happen.”

Khan said on Monday, “I challenge Reddy, the coward, to unsheathe his sword and cut me down first. It is absolutely shameful for a legislator to speak such things against a particular community. Why is Prime Minister Narendra Modi, who often says Sabka Saath, Sabka Vikas, silent?”

On his part, Reddy on Monday said he stood by what he said. “What I meant was you Muslims should not get swayed by CAA protests and damage public property. We [Hindus] are sons of the same mother and live peacefully. However, they [Muslims] should not test our [Hindu] patience. I stick by my words 100%,” he said.

A delegation of the Ballari district Congress unit also submitted an appeal to the deputy commissioner, inspector general of police and superintendent of police on Monday to arrest Reddy for his provocative speech.

Mangaluru, May 26: In the wake of mounting case of covid-19 in the coastal Karnataka, the police department has decided to sanitise the police stations in Dakshina Kannada and Udupi districts.

The superintendents of police in both the districts have been instructed to take necessary steps for sanitisation of stations in a phased manner, according to Devajyoti Ray, inspector-general of police (Western Range).

Meanwhile, the top cops of Uttara Kannada and Chikkamagaluru that forms part of the Western Range have been asked to take a call on doing so. “Hebri police station in Udupi was sanitised as part of this process and not because of any positive case emerging from staff there,” he said.

Allaying fears over stations being sealed down over positive case among station staff, Karnataka police chief Praveen Sood said this is a temporary measure and stations do not become non-functional.

“It is just that, for a mandated period police station will function from different premise when the station is being sanitised,” he said.

Noting that policemen are quarantined as precautionary measure, he said additional staff can be drafted from other stations or districts if need for it arises.

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
