Former Mangaluru Mayor Ashraf joins Congress party once again!

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Kozhikode, Jan 26: The Indian national flag was unfurled at around 10,000 mosques and religious institutions across Kerala on the auspicious occasion of 71st Republic Day on Sunday.

"The national flag was unfurled at around 10,000 mosques across the state on this auspicious occasion as per the instruction of the Waqf Board," Secretary of the Kuttiady Juma Masjid Committee, K Basheer, told media here.

He said that the national flag was also unfurled at the Kuttiady Juma Masjid here as per the instructions.

"Constitution is under threat by the Citizenship Amendment Act, we also read the preamble of the Constitution in solidarity," Basheer said.

Bengaluru, Jun 20: A petition has been filed in Karnataka High Court to transfer Amulya Leona case to the National Investigation Agency (NIA). She raised pro-Pakistan slogans at an anti-CAA rally on February 20 at Freedom Park.

The petition, filed by advocate Vishal Raghu, blamed the probe team for not filing chargesheet on time and suggested the state government to approach the higher court against bail granted to Amulya Leona.

On June 11, she was granted conditional bail by the Bengaluru civil court.

She was charged with sedition for her actions in the presence of All India Majlis-e-Ittehad-ul-Muslimeen chief Asaduddin Owaisi.

The court granted bail after hearing the bail application. Amulya's advocate on behalf of the petitioner said, "the petitioner is just a 19-year-old lady and she is studying in a private college in the Bengaluru. She shouted 'Pakistan Zindabad' but she never mentioned Pakistan as her country."
