Zinc Oxide (ZnO) thin films have been deposited for five different molarity (M) of Zinc acetate hydrated (0.075, 0.1, 0.125, 0.15, 0.175 M) using simple spray technique to study the effect of Zinc ion concentration on structure, morphology and optical properties. The XRD patterns of deposited ZnO thin films show tetragonal crystal structure with wurtzite symmetry. The effect of molarity on morphology was studied using Scanning Electron microscopy (SEM). The elemental analysis was studied by usin...
Applications of Distributed Renewable Energy Sources (D-RES) in distribution system are increasing rapidly. But, integration of these renewable energy resources into distribution systems results in more problems in protection related issues such as mis-coordination, and changes the direction of fault currents. The coordination of Directional Over-Current Relays (DOCRs) is a very critical task for appropriate functioning of the electrical power system in presence of D-RES. In this paper, a Partic...
In this paper optimal reactive power problem is solved by Mountain Zebra Algorithm (MZA), Augmented Bat algorithm (AB) and Improved Kidney Search (IKS) algorithm. Mountain Zebra Algorithm (MZA) emulates the searching techniques of the Mountain Zebra behaviour. Mountain Zebra search in group to find the food. Alike to plain zebras, Mountain zebras do not be in cumulative into big herds; only they structure as small family groups consisting of a solo stallion around one to five mares, jointly with...
This paper presents Dynamic Membrane Evolutionary Algorithm (DMEA) has been applied to solve optimal reactive power problem. Proposed methodology merges the fusion and division rules of P systems with active membranes and with adaptive differential evolution (ADE), particle swarm optimization (PSO) exploration stratagem. All elementary membranes are amalgamated into one membrane in the computing procedure. Furthermore, integrated membrane are alienated into the elementary membranes 1, 2,_, m . I...
Herein, the adsorption of heavy metal ions thiol modified oak charcoal was investigated. The obtained modified charcoal has been characterized by X-ray diffraction, granulometric analysis and infrared spectroscopy. Then, its adsorption efficiency for the removal of Cd 2+ , Cu 2+ and Pb 2+ from aqueous solutions was tested. The effects of contact time, pH, electrolytes and initial metal ions concentration on metal ions removal were investigated. The adsorption capacities were high (197, 250 and 2...
This paper projects Opposition based Red Wolf Optimization (ORWO) algorithm for solving optimal reactive power problem. Each Red wolf has a flag vector in the algorithm, and length is equivalent to the whole sum of numbers which features in the dataset of the wolf optimization (WO). In this projected algorithm Red wolf optimization algorithm has been intermingled with opposition based learning (OBL). By this amalgamate procedure the convergence speed of the projected algorithm will be increased....
Extracting Phytochemicals or phytocompounds for the upliftment of general health and sustainability is one of the greatest need of the millennium. Plants has immense quality in regards of secondary metabolites although not required for general growth and development yet are very much necessary for forming a protective gear and maintaining homeostasis . With their immense diversity in curing various diseases, these plants secondary metabolites are therefore must be put forth and give much importa...
Information is a vital thing that needs to be secured and well protected during transmission between two or more parties over the internet. This can be achieved by steganography technology. Steganography is the science of concealing the information inside other information in a way that the concealed information cannot be detectable by the human eye. Many ways are available to hide information inside a cover media such as text, image, and audio steganography, but image steganography is the most ...

Groundwater is the single largest source of irrigation water supply. This review collected secondary data of hydro geochemical parameters and irrigation water quality indexes of groundwater from selected 11 Districts of Bangladesh for assessing the suitability of irrigation water. Several irrigation water quality indices, including soluble sodium percentage (SSP), sodium adsorption ratio (SAR), magnesium adsorption ratio (MAR), residual sodium carbonate (RSC), Kelly’s ratio (KR), permeability in...
