A Review of Fish Taxonomy Conventions and Species Identification Techniques
Taxonomists, ecologists, geneticists or researchers from other biological fields who wish to adopt fish as a constituent of their studies often become discouraged when they find that ichthyology is a complex subject. In fish-based studies, the failure to recognize fishes as distinct biological units can lead to wrong diagnosis. Hence, this review paper attempts to clarify and discuss the latest...
متن کاملAntioxidant, Metal Chelating, Anti-glucosidase Activities and Phytochemical Analysis of Selected Tropical Medicinal Plants
The purpose of this investigation was to determine the antioxidant potentials and anti-glucosidase activities of six tropical medicinal plants. The levels of phenolic constituents in these medicinal plants were also quantified and compared. Antioxidation potentials were determined colorimetrically for scavenging activities against DPPH and NO radicals. Metal chelating assay was based on the mea...

متن کاملImproving Hydrophilicity of Polyethersulfone Membrane Using Silver Nanoparticles for Humic Substances Removal
Silver-impregnated membrane was facilely prepared by ex situ silver nanoparticles (NPs) blending method using polyethersulfone (PES) as the base polymer. A total of three membranes [F1(S0), F2(S0.5) and F3(S2.0)] were fabricated at different weight percentages of polymer and silver (Ag) loadings to compare their effects on membrane morphological and performance properties. All membrane types we...
