Former Karnataka Governor T N Chatruvedi passes away

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Feb 3: The Karnataka government is probably the only state to have so many nodal agencies to deal with investment proposals. There is the KIADB, Karnataka Udyoga Mitra, State High Level Clearance Committee (SHLCC), State Level Single Window Clearance Committee (SLSWCC) and District Level Single Window Clearance Committee.

While the government claims these have been created to speed up the process of setting up industries, they’re only delaying it. “A four-to-five year delay in acquiring land has become the norm,’’ say industry sources.

“These entities are only adding layers of obstacles to investors and is not really helping industries,” said a senior IAS officer.

While DLSWCCs are headed by deputy commissioners are empowered to clear investment proposals up to Rs 15 crore, SLSWCC, headed by the industries minister, clears proposals more than Rs 15 crore and up to Rs 500 crore. Proposals worth more than Rs 500 crore have to be cleared by SHLCC chaired by the CM. These entities have to meet regularly and clear proposals. But often, these meetings don’t happen as scheduled. “The delay starts from here,” said Vasant Ladava, industrialist and member of Karnataka Industries and Commerce, Bengaluru.

The single-window agencies involving representatives of departments like industries, revenue, pollution control board and forest are supposed to collectively give necessary clearances required for industries. “But, of late, they have become only project approvers without other responsibilities, leaving investors in the lurch,” said Ladava.

Mangaluru, May 8: After continuous pressure on Union government from Karnataka NRI Forum- UAE, the first special flight carrying 180 Kannadigas who stranded at UAE due to Covid-19 pandemic will fly from Dubai to Mangaluru on May 14.

The special flight will take off from Dubai at 4.10 p.m. UAE time to reach Mangaluru at 9.10 pm IST on May 14. Earlier it was reported that the flight will operate on May 12. However, sources of Mangaluru International Airport and Air India today confirmed that first flight will be on May 14.

The state government has directed Dakshina Kannada and Udupi districts authority to quarantine all passengers once they reach.  

All Kannadigas will be given permission to travel back home only after they test negative in Covid test at Dubai airport.

In fact, Karnataka was missing in the list of states to receive special flights when Ministry of External Affairs arranged them to bring stranded Indians at UAE. Special flights were arranged only to Kerala and Tamil Nadu people stranded at UAE in the first stage.

Thanks to Karnataka NRI Forum of UAE which opened helpline (https://uaekannadahelpline.club) to seek assistance to Kannadigas, nearly 2000 Kannadigas have registered for assistance in which 127 pregnant women, 27 senior citizens, 700 people who have lost jobs aftermath of coronavirus sought assistance from NRI forum.

After providing food and shelter to Kannadigas who lost jobs at UAE since March 2020, NRI forum put pressure on both state and Centre to arrange special flights to send them to home. 

The NRI Forum has approached Indian Consulate at UAE and chief minister BS Yediyurappa to evacuate Kannadigas, but got no response. Following this, Karnataka NRI Forum President Praveen Shetty approached Union Minister for Chemicals and Fertilizers DV Sadananda Gowda for help. Gowda immediately responded the call and he spoke to MEE to arrange special flight for Kannadigas as well.

Indian government has promised to arrange special flight to Mangaluru or Bengaluru by next week to bring Kannadigas.

Comparing to other Indian States, Karnataka has the highest number of its people working in UAE. Around 1.25 lakhs Kannadigas are working in UAE in which majority are working classes. Due to Covid-19 pandemic thousands of workers have lost jobs, Mr. Shetty explained.

"Indian government had arranged special flights from US, UK, Singapur and other countries to bring back Indians, but excluded UAE in the list. Actually, lakhs of Indians are working in UAE as labourers and in odd jobs, the government should have given first priority to bring labourers rather rich one", he opined.

"BJP has 27 MPs from Karnataka. We continuously requested all BJP MPs and state government but none of them came to our help. Thanks to Mr Gowda for his timely intervention to bring stranded Kannadigas", Mr Shetty said.
