New Delhi, May 20: In further relaxation of lockdown rules, domestic flights will begin operations from May 25 in a calibrated manner. Currently, only cargo and evacuation flight services are allowed.

The nationwide lockdown to halt the spread of coronavirus is in place till May 31. However, certain relaxations have been allowed.

All airports and air carriers are being informed to be ready for operations from next week, tweeted civil aviation minister Hardeep Singh Puri.

The standard operating procedures for passenger movement will be separately issued by the ministry, said the minister.

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Chikkamgaluru, Feb 21: Wazi Noronha, aka, Vojald, the father of Amulya Leona Noronha, who lives in Koppa taluk of Chickmagalur district has said that he was shocked by his daughter’s pro-Pakistan slogans.

“Let her rot in jail. I don’t mind if police break her bones, I don’t support what she said and I will not approach lawyers for her bail. She has committed a grave mistake,” he said.

Amulya, a 19-year-old student activist, was booked for sedition yesterday after she raised ‘Long Live Pakistan’ slogans at a CAA-NRC rally. A visibly embarrassed Asaduddin Owaisi, AIMIM chief and MP tried to snatch the mic away from her and slammed her. Karnataka Police have registered a case under IPC Section 124A (Offence of sedition) against Amulya.

Mr. Wazi, who owns a two-acre areca plantation and runs a poultry farm, said he would not make any attempts to get her bail. “Let the law take its course. I cannot approve of her statement,” he said.

He said he had cautioned his daughter against getting involved in protests. “I told her to complete studies first and later she could fight for poor people. But what she said yesterday is not acceptable. I don’t know what made her so. I hope a probe would bring out who prompted her to make such statements,” he said.

Mr. Wazi also admitted that he was associated with BJP and had worked for saffronite leaders like Shobha Karandlaje and D N Jeevaraj.
