COVID-19 Impacts on Agriculture and Food Security
Abstract: COVID-19 and lockdown originally had the effect that the shift in demand curve to the left resulted in "leveling off" the prices of agricultural produce. The reason for this was not the lack of demand due to rising prices. The reason for this was that due to their consumption being limited to homes and lack of workers, most companies were forced to reduce production in their factories. The coronavirus pandemic …

Acute and Chronic Toxicity of Fluoride and Aluminum on Plant and Animal Models
Abstract: Ecotoxicological studies revealed aluminum (Al2SO4. 24 H2O) to be more toxic than fluoride (NaF) on a battery of test organisms (EC/LC50 of Al = 0.308 1.46 ppm; F = 116.6 232.8 ppm). During chronic exposure (Al = 3 ppm, F = 10 ppm for 60 90 days), there was reduction in growth parameters of organisms at different trophic levels in a food chain such as producers {dry weights (6.7 29.0) …

Histopathological Effects of Silver Nanoparticles on Gills and Liver of Freshwater Fingerlings Catla catla (Ham.)
Abstract: Fish is the best biomarker to identify the adverse effect on surroundings. Here, the fingerlings of major carp (Catla catla) were used as a model in the present work to investigate the toxicity caused by silver nanoparticles (AgNPs). The fish exposed to different concentrations of 10 μg/L and 30 μg/L AgNPs for 15 days were sampled at days 5, 10 and 15 for histology. This exposure caused organ injuries, and …

Impact of Hexavalent Chromium on Histopathology in Freshwater Stinging Catfish Heteropneustes Fossilis
Abstract: Acute toxicity of Cr (VI) (as K2Cr2O7) to freshwater stinging catfish, Heteropneustes fossilis and its histopathological impacts on gill and liver tissue were evaluated. Fish showed behavioral alterations after K2Cr2O7 exposure and 96 h-LC50 was 35.724 mg/L in static bioassay. Fish were exposed to three sub-lethal concentrations (concentration I=1/4th of 96 h-LC50, concentration II=1/10th of 96 h-LC50 and concentration III=environmental concentration of Cr reported in the river Buriganga). Blood, liver …

Detect the Edges of Hygienic Images and De-Noised Images Using Meta Heuristic and F-Ratio
Abstract: AbstractEdge detection is one of the important parts of image processing. It is essentially involved in the pre-processing stage of image analysis and computer vision. It generally detects the contour of an image and thus provides important details about an image. So, it reduces the content to process for the high-level processing tasks like object recognition and image segmentation. The most important step in the edge detection, on which the …

Dietary Influence of Selected Botanical Additives on Growth, Body Coloration and Carcass Composition of Juvenile Yellow Morph, Labidochromis caeruleus
Abstract: The authors evaluated the effect of four botanical additives (Hibiscus rosa-sinencies, Chrysanthemum indicum, Thespesia populnea and Tagetes erectes) on growth, body coloration and carcass composition of an ornamental cichlid yellow morph Lebidochromis caeruleus. The xanthophilic sources were added to the supplementary diets at 5, 7.5, 10, 12.5 and 15% levels along with a control diet without xanthophilic sources. Among the four xanthophilic sources tested, highly pronounced body coloration of fishes …

Phylogenomic Analysis of Human Multigene Families Using Computational Approach
Abstract: Evolution leads to major morphological transformations and anatomical complexity achieved by higher vertebrates. The phylogenomic analysis of human multigene families (ERBB, HCK, VAMP) was conducted to check the evolutionary history and functional significance. The colossal amount of diversified protein dataset for a wide variety of vertebrates and invertebrates was used to derive the phylogeny of highly significant and functionally diverse gene families. Phylogenetic analysis reveals the mode of evolution and …

Biotechnological Prospective of a Group of Beneficial Extremophiles Isolated from Different Sources
Abstract: Extremophiles thrive in terrestrial hot springs, hydrothermal vents, glacial ices, saline lakes, solar saltern and acidic and alkaline niches; moreover a group of the extremophiles may grow in household hazardous waste, solvents containing cleaning and polishing chemicals, heavy metals contaminated sites, or in several other habitats such as aphotic, anoxic, athalassohaline and thalassohaline habitats that were previously considered inhospitable for life. Beside aforementioned extreme niches, extremophiles also dwell in poultry …

Marine Supplements and Depression: A Critique
Abstract: Depression is the common cold of psychiatric illness. It affects millions of people to varying degrees. It has a predisposition to attack its ‘victims’ without any apparent reason, albeit current research supports the credo that complex psychological, environmental, and biochemical changes could trigger and also ‘engender,’ the initial mood swing. Conventional medications do not provide long-lasting results; they are also not free of side-effects in the long run. Marine dietary …

Comparative Study Between Dashavatara (Incarnation) and Darwinian Theory of Evolution
Abstract: The word Dashavatara derives from Dasha, meaning “Ten”, and Avatara, roughly equivalent to “Incarnation”. Lord Vishnu manifested in various avatars to safeguard the universe and reinstate “peace and dharma” during the four distinct yugas, or cosmic cycles. The Hindu text Dashavatara, which describes ten forms of Lord Vishnu, has a better developed theory of evolution than the hypothesis put out by English scientist Charles Darwin in the 17th century. Objective …
