Allelopathic effects of plant litter have been extensively studied, but less attention has been given to the dynamics of phytotoxicity during the decomposition processes. Argemone ochroleuca, an invasive weed, suppresses ...
The consumption of raw meat has associated with cultural practices and widespread raw beef
consumption habit that can be a potential source for food borne illnesses in Ethiopia.
Therefore, the present study was intended ...
The Particle Swarm Optimization algorithm has been empirically shown to perform well on many optimization problems. However, it may easily get trapped in a local optimum (premature convergence) when solving complex multimodal ...
Biomaterials have been used as biosorbents either in raw or chemically modified forms. The main aim of the present research work was to synthesize activated biocarbon from leaves and seeds of Lantana camara as biosorbent ...

Biosorption is the most promising technique to decolorize, separate, and pre-concentrate liquid and gaseous mixtures to facilitate the removal of harmful chemicals because of its efficacy, easy operation, non-toxicity, and ...
This study is to present an electroweak description of neutrino-induced electron-positron pair
production in the presence of a strong background magnetic field. The determination of the
scattering matrix, scattering ...
Blood is the red viscous fluid that circulates around the body supplying O2 and nutritive substances to the tissues and returns CO2 to lungs and metabolites to the kidneys, for regulation of body temperature, and distributes ...
