Abstract A nanocrystalline and porous p-Polyaniline/n-WO3 dissimilar heterojunction at ambient temperature is reported. The high-quality and well-reproducible conjugated polymer composite films have been fabricated by oxidative polymerization of anilinium ion on predeposited WO3 thin film by chemical bath deposition (CBD). X-ray diffraction analysis of the deposited WO3 films revealed that as-deposited film was amorphous; however, an amorphous-to-crystalline phase transition was observed by ...
ABSTRACT Performance analysis is the task of monitoring the behaviour of a program execution. The main goal is to find out the possible adjustments that might be done in order to improve the performance of the computer system in use. To be able to get that improvement, it is necessary to find the different causes/contributors of overhead. Today, we are already in the multicore era, but there is a gap between the level of development of the two main divisions of multicore technology (hardwar...
ABSTRACT Personnel department is service-oriented towards staff and entails day-to-day activities of units some of whose functions overlap and involves recruitment of staff, retirement of staff, termination of appointment, processing of request for sabbatical leave, staff training and development, pension funds administration, health management organization, etc., and will be easier, faster and secure adopting a virtual approach rather than its manual counterpart. This project work will e...
ABSTRACT In this study, a series of N-pyridin-3-yl substituted [phenylsulphonamido] acetamide has been synthesized. The reaction of phenylsulphonyl chloride with various amino acids in basic medium yielded phenylsulphonamido alkanoic acid which, on chlorination with thionyl chloride, gave acid chloride derivatives of phenylsulphonamido alkanoic acid in situ. The acid chloride derivatives on condensation with 3-aminopyridine gave corresponding acetamide in good to excellent yield. The compoun...
ABSTRACT A shallow geophysical investigation for road surface failure using 2D electrical resistivity imaging profiling was conducted to produce an approximate model of the subsurface resistivity. This study was done with the aim of revealing the horizontal and vertical geological discontinuities using electrical resistivity, an intrinsic property of all materials. Probable zones of untimely failure along the road are then investigated by variation in resistivity. Four traverses were establi...
ABSTRACT Management of hyperglycemia is an essential strategy in control of diabetes mellitus which remains a major health problem despite several therapeutic interventions particularly inhibitors of a-amylase. Use of ethnobotanical options has prominently been reported, for instance, Lannea schweinfurthii reported for management of hyperglycemia, although there is no scientific information to validate its anti-hyperglycemic potential. The study was to determine structures of compounds from L...
Abstract The current approach of morbidity control of schistosomiasis, a helminth disease of poverty with considerable public health and socioeconomic impact, is based on preventive chemotherapy with praziquantel. There is a pressing need for new drugs against this disease whose control entirely depends on this single drug that has been widely used over the past 40 years. We argue that a broader anthelminthic approach supplementing praziquantel with new antischistosomals targeting different p...
Abstract This project work analyzed the relevance of the Email in modern business practices and organization. As SMEs and large firms expand, they are faced with the problem of managing numerous staff dispersed in diverse field offices. There is a need to send up-to-date information about their products to a larger clientele. The proposed system design provides a management tool that handles employee task management, internal communication and information dissemination. The new system desig...
Abstract Introduction: Lead is an oxidation reduction inactive metal however it interacts with a group of essential elements such as copper, zinc, selenium and chrome and iron. Accordingly current study aims to evaluate the effect of occupational Lead exposure on zinc and chromium level among factory workers. Materials and Methods: A cross-sectional study included 41 Lead exposure workers and 40 non exposure subjects as control group. Serum chromium and zinc were measured using Atomic Absorp...
Abstract Scale, sludge and sand samples were collected and analysed using thallium activated sodium iodide NaI(Tl) spectrometer to determine type, activity concentration, absorbed dose rate and annual effective dose of naturally occurring radioactive material (NORM) of samples collected from oil fields at West Kourdofan state. Scale radionuclides was found to be, 238U, 232Th and 40K at concentrations ranged from (4106.9 - 358.05) Bq/Kg, (2736.7 - 375.88) Bq/Kg and (9294 - 16.07) Bq/Kg respec...
ABSTRACT This work suggests an exact and systematic model identification approach which is entirely new and addresses most of the challenges of existing methods. We developed quadratic discriminant functions for various orders of autoregressive moving average (ARMA) models. An Algorithm that is to be used alongside our functions was also developed. In achieving this, three hundred sets of time series data were simulated for the development of our functions. Another twenty five sets of simul...
ABSTRACT Solution growth technique was used to deposit thin films of Manganese Suphide (MnS), Calcium Sulphide (CaS), Magnesium Sulphide (MgS), Barium Sulphide (Bas), Zinc Fluoride (ZnFz) and Calcium Oxide (CaO) on micro-slides (Substrates) at different bath parameters which include temperature, molarity of solution, Volume of solution and water, time of d.eposition and pH. The absorbance, A was measured using spectrophotometer ranging from ultraviolet to visible regions. The Transmittance, ...
ABSTRACT This research investigated the effect of magnetic field on the thermal conductivity of high temperature type II superconductors. The result suggested that the thermal conductivity of high temperature type II superconductor YBa2Cu3O7- decreases as the applied magnetic field increases at a given temperature. We also found out that the superconducting energy gap of YBa2Cu3O7- decreases in response to increasing temperature and applied magnetic field. At a critical temperature of ...
ABSTRACT
Drinking water quality was investigated at Daranna community the mineral rich part of Kaoje town in Kebbi state, to ensure the continuous supply of clean and safe drinking water for the public health protection. In this regard, a physical and chemical analysis of drinking water samples was carried out for samples collected at different locations within the community areas. A number of parameters such as colour, temperature, pH, electric conductivity, dissolved oxygen, total hardness, COD, ...
