Man arrested under Wildlife Protection Act for biting snake to death in Karnataka

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of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.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

Dubai, May 12: Free tickets are being offered by philanthropists and businessmen based in the UAE for deserving Indians who want to fly home.

Repatriation ticket prices have been set at around Dh700 to Dh750 per person depending on the destination. But there are many in UAE who cannot afford it, especially people who have lost their jobs or have medical concerns.

Malayalam Communications Ltd and its Malayalam stations (Kairali TV & Kairali News) are giving away 1,000 tickets free. Those who wish to apply can submit their application to [email protected].

Indian businessman Dhananjay Datar, chairman & managing director of Al Adil Trading Company, is also giving away 300 tickets. He is liasing with the Consulate General of India (CGI) for the names. “This is the time we need to rise as a community,” he said.

Besides taking care of airfares, Datar will also bear the cost of COVID-19 testing fees for Indians from the UAE.

“The repatriation efforts undertaken by the government of India is one of the largest initiatives. I am just doing a small bit to help the community. There are many people who are not in a position to meet the airfare and COVID testing costs as they have lost jobs. I will be coordinating with authorised entities handing this to lend my support,” he said.

Pravasi India Forum, a welfare organisation in UAE, is giving away 100 tickets. The NGO on Monday, May 11, uploaded a registration form where people can provide their details. “Tickets will be given to those approved by CGI and for those who are in financial distress,” said Abulaise, president of Pravasi Welfare Forum.

Punnakan Mohammed Ali, general secretary Incas UAE committee, said it is also ready to give away hundreds of free tickets but only to genuine candidates. “We will evaluate each individual and only if they are approved by the consulate, we will give the tickets. But we are ready to help.”

Those who want to register can get more details on www.pravasiwelfareforum.com.They can also call 055-1025611.

Need for more flights

The gesture notwithstanding, many Indians are still waiting to get news on their repatration.

Social worker Shukoorali Kallangal, President, Abu Dhabi Kerala Muslim Cultural Centre (KMCC), urged the government of India to add more flights to accommodate more passengers.

“Emergency repatriation services are the need of the hour. There are several expats with medical, financial distress. For those who came with the hope of a job – that too is a thing of the past now. Right now all they want is to go home and start something afresh there.”

Kallangal said: “Take the case of pregnant women. In many cases, their husbands have lost jobs or have been asked to go on unpaid leave. They are living hand to mouth and cannot afford medical costs. Due consideration should be given to them.”

Sreedharan Prasad, another social worker based in Ras Al Khaimah, said he is currently dealing with several emergency medical cases.

Consul General of India Vipul said plans are afoot to add more flights in the next phase of Indian repatriation. “The number of flights are being decided by India in consultation with state governments. This is not a normal situation we all are in. We are in the middle of a pandemic situation.”

Mangalore University has been participating in the campus bird count a sub-event of ‘Great backyard bird count’ (GBBC) organized by Bird Count India for the past 5 years. This year, CBC was held from 14th to 17th February of 2020 across various campuses in India.

This year the four days event was successfully ended up with the sightings of 103 species of birds from various locations across the campus spread on 300 acres. In this Black Drongo, Black Kite, Brahminy Kite, Common Iora, Green Wabler, Purple-rumed Sunbird, Red-whiskered Bulbul, White-cheeked Barbet, Jungle Babbler and Plum headed parakeets were the common birds, and also observed House Crow with nest and nestlings, Indian Robin nest with eggs, Bronzed Drongo constructing the nest and Shikra mating and carrying nesting materials.  Whereas Yellow-billed Babbler is rare in the campus, Ashy Drongo, Barn Swallow, Booted Eagle, Grey Wagtail, Indian Pitta etc. were migratory birds, Grey-headed Bulbul (Near Threatened bird), Rufous Babbler and Grey-headed Bulbul were Western Ghats Endemics  and Brown Wood Owl, Barn Owl, Spotted Owlet, Nightjars (Savanna, Indian and Jerdon’s) and Sri Lanka Frogmouth were nocturnal birds. Blue-eared Kingfisher Grey-bellied Cuckoo which was very rare and new additions to avian list of the campus.

In the first year (2016) of Mangalore University’s CBC recorded 77 species, in 2017 recorded 95 species, in 2018 recorded 110 species and in 2019 recorded 107 species of birds. However some of the common species like Rose ringed parakeets, Blue tailed bee-eater, Nilgiri Flowerpecker and Indian roller etc., sighted last year were not seen this year. But with 2 new additions from this CBC, the checklist of Mangalore University Campus has been updated with a total of 141 species.

This event was coordinated by Vivek Hasyagar from the Department of Applied Zoology and Maxim Rodrigues from the Department of Marine Geology. Survey trails were led by more than 60 students and research scholars from various Departments of Mangalore University includes Applied Zoology, Biosciences, Microbiology, Botany, Physics, Chemistry and Material Science.  In addition, some enthusiastic participants from St. Aloysius College had involved in identifying the birds around the campus.

Quote:

Wild/planned fire affects negatively on the existing ecologically sensitive areas in and around the campus especially in lateritic grasslands. Because many insectivorous birds are dependent on these lateritic grassland habitats for their food and breeding grounds for many ground dwelling birds like Yellow wattled lapwing, Red wattled lapwing, Indian Robin and Barred buttonquails. Conserving these habitats will be helpful in protecting these birds.

Quotes from the participants: “The Campus Bird Count 2020 at Mangalore University was an experience of its own kind. Observing birds in their natural habitat gave me new perspective of viewing them not only as another living being, but as equals, or even of higher intelligence. The Campus Bird Count is an important step towards documenting bird life year after year, and creating awareness amongst youngsters, so that proper conservation steps can be taken to protect them from human interference”.
