Ullal Dargah Urs from April 2 to 26, preparation begins

Mangaluru, June 17: As many as 47 buses have been arranged by the district administration to transport 1,043 II PU students from the border areas of Kerala to the respective examination centres in Dakshina Kannada.

The II PU English examination, which was postponed in Karnataka due to covid lockdown, will be held on June 18. A total of 26,942 students are expected to appear for the examination across the district. Among them 6322 students have chosen to write their exam in the centres near to their hometown, following the COVID-19 pandemic. As many as 1,043 students are expected to come from Kerala.

22 KSRTC buses and 11 schools buses have been arranged from Talapady toll gate near Mariyashrama Church, 2 each KSRTC buses from Punyakoti Nagara in Mudipu, Bayar and Anekal in Vittal border, 1 KSRTC bus from Pathur in Kurnadu border, 3 KSRTC buses from Saradka in Vittal border, school buses from Kayar Padav in Puttur border, Panjikallu in Sullia border, Karike in Sullia border and Alatti Baddadka have been arranged.

The students have been asked to be present at a designated place to board the bus at 7 am and have to get their hall ticket and identity card, said DC Sindhu B Rupesh.

All the students should mandatorily wear masks and use sanitisers before entering the examination centres. The principals of colleges, where students from Kerala, are studying have been asked to deploy staff to make arrangements to ensure that students reach the examination centres on time and get back home after the exam.

Udupi, June 10: Philanthropist and businessman Haji P K Abuswalih Kannangar passed away today at a private hospital in Mangaluru. He was 85. 

He was a resident of Pombathota house at Kannangar in Kaup taluk of Udupi district.

He was the proprietor of Green Store in Mudigere for past five decades and also was a coffee planter. 

He had served as the president of Muhayaddin Juma Masjid at Mudigere Hand-post in the past. He was also former president of Mudigere Taluk unit of Indian National Congress.

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
