Meat industry generates various wastes such as effluent, emissions and solid wastes that pose environmental and health problems. The effluent released from the meat industries finds its way into the natural water resources and degrade the water quality. The solid wastes of meat industry create a public nuisance by way of foul smell if it is not handled properly. The effluents, as well as solid wastes of meat industries, are po Read More

From the past three to four decades, ecologists and scientists have exhaustively studied the effect of increased artificial light pollution at night on the ecological and physiological behavior of mammals. The Suprachiasmatic Nuclei (SCN) or master clock in the brain of mammals including humans synchronizes the physiological functions with the light: dark cycle. The prolongation of light period in the light: dark cycle disrupt Read More

Objective: Selective removal of phenol from organic solvent mixture (benzene + toluene + hexane) or other petroleum by-products have a major concern. Hence, the experiments were conducted on the removal of phenol from synthetically prepared phenolic organic waste by using a green process, ionic liquids. Methods: The ionic liquids, 1-ethyl-3-methyl imidazolium cyanoborohydride, and 1- butyl-3-methyl imidazolium hex Read More

Background: The demand of an efficient nanocarrier in drug delivery, graphene and its derivatives are emerging as a rising star due to its remarkable chemical and structural properties. Objective: Graphene oxide (GO) has high surface area and ability to load high amount of aromatic drugs. Hence, the objective of the research was to load Trihexyphenidyl hydrochloride (THP), antiparkinsonian drug on GO ultrasonically Read More

Background: Atomic Absorption Spectroscopic (AAS) method is most commonly being used due to its reproducibility of results, short analysis time, cost effective, lower level detection and hyphenated in nature. Aims: The concentrations in mg/kg of six heavy metals of environmental implications which includes Cd, Cu, Fe, Mn, Pb and Zn were determined by Atomic Absorption Spectrophotometer PG Instrument Model AA090M046. Read More

Objective: The main focus in the current work is to investigate how diverse heating systems and their locations influence the indoor thermal environment in an exhaust- ventilated room. Methods: Four systems for heating the room were used in the current study, in which, heat was transferred by convection and radiation. The four systems were: wall and floor heating at low temperatures, Medium Temperature Radi Read More

Background: Effective treatment of wastewaters for potentially toxic metals especially at affordable cost is critical to the well-being of man and the environment. Objective: This study optimized the conditions for the application of Calophyllum inophyllum seed husk as biosorbent for simultaneous removal of heavy metals from aqueous solutions and investigated the removal efficiencies of the biosorbent for Pb2+ and Cd2+ in wast Read More
