ABSTRACT
This paper discusses facts and fictions of poplar (Populus deltoides) in Jammu and Kashmir, India. Recently, after the COVID-19 outbreak, it was claimed that 'pollen grains of female poplar may be carriers of the SARS-CoV-2 virus'. The Government of Kashmir issued an order for the felling of about 42,000 female poplar trees, even though many environmentalists and scientists provided evidence that pollen from poplar causes meagre effect on human health when compared to other trees and it has no relation with COVID-19. Experts also suggest that the silky cotton seed of poplar may not cause much harm, but it has been misinterpreted due to carrier nature of other pollen grains. On the other hand, unscientific harvesting of millions of poplar trees could result in desert-like conditions in the future and also affect the livelihood opportunity of farmers and local people in J&K.
ABSTRACT
COVID-19 is a respiratory infectious disease caused by a novel coronavirus-II. COVID-19 has affected a few millions of people across the globe with alarming death toll rate. Chest X-rays are widely available modality for immediate care in diagnosing COVID-19. X-ray images inherently possess significant amount of noise, and image resolution depends on radiation dosage. Diagnosis of COVID-19 chest X-rays would be more precise with high-resolution images. The aim of the current work is to explore selected super-resolution techniques for COVID-19 chest X-ray images. The samples are taken from COVID-19 chest X-ray public dataset. We conducted the experiments on COVID-19 chest X-ray public dataset. The super-resolution methods produced high resolution chest X-ray images the clear view of the pulmonary opacities in chest x-ray images. Evaluation metrics used in the experiments demonstrated improvement in overall quality enhancement of the chest X-ray images. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
ABSTRACT
BACKGROUND: Novel coronavirus has recently gained attention of the global community after it was first reported from Wuhan, China. It has been declared as global health emergency with implications to all people. Droplets of bodily fluids, such as saliva or mucus, from an infected person are dispersed in the air or on surfaces by coughing or sneezing and could be the main source for the further spread of infection. All healthcare professionals including Dental Surgeons should help to prevent transmission of this deadly virus. It's a virus affecting both human and animals and spreads from animals and person to person in close proximity, similar to other respiratory illnesses, such as the flu. This review article mainly highlights the types, epidemiology, transmission and addresses the implications of 2019 n-CoV from the health professionals perspective and discusses the necessary preventive precautions that should be strictly followed in a dental setup so as to prevent further spread of infection.
