ABSTRACT Azo dyes have become an immerging and difficult pollutant to the environment. Industrial activities have resulted in disposal of these toxic dyes in effluent and among them is methyl orange (MO) dye. Proper effluent treatment schemes have become a necessity so as to be able to reduce the potential toxicity issues regarding plant and animal life due to the rise in demand for clean and safe water. Several methods have been applied for the removal and degradation of MO dye but have prov...
ABSTRACT Monitoring is very important in Industrial Automation to bring out reliability and accuracy thus the use of a SCADA system. SCADA is an acronym for “Supervisory Control and Data Acquisition.” This systems are widely used in industry for supervisory control and data acquisition of industrial processes. A Android-enabled mobile phone can be used as a client in a SCADA application in order to display and supervise an industrial refrigeration system. The project presents an actual im...
ABSTRACT Carbon nanodots (CNDs), nitrogen doped carbon nanodots (n-CNDs) and their composites with cobalt tetra aminophenoxy phthalocyanine nanoparticles (CoTAPhPcNPs) were employed towards the simultaneous detection of aspirin (ASA), ibuprofen (IBU) and indomethacin (INDO). The nanomaterials were characterized by FTIR, UV-Vis, TEM, cyclic voltammetry, electrochemical impedance spectroscopy, linear sweep voltammetry, chronoamperometry and differential pulse voltammetry. CoTAPhPcNPs/n-CNDs-GCE...
Abstract The study assessed the challenges faced by students in using Information Communication Technology (ICT) at primary level. The research was carried out in Cluster five of Glenview Mufakose District in Harare. In order to get an insight on the challenges, different authorities were reviewed. The descriptive survey design was adopted in this study. Probability and non-probability sampling techniques were employed in order to select participants in this research. Five teachers, twenty pu...
ABSTRACT This work examined thermo-mechanical and metallurgical parameters (temperature and cooling rate) that give rise to substantial improvement in the basic functional strength characteristics of high-yield reinforcing steels produced in a conventional mill. A new process tagged Temperature Tracking-Jet Water Spray (TT-JEWAS) was developed to achieve requisite in-process control of thermal variations on one hand and fast undercooling by spray quenching on the other. The alternative micro...
SUMMARY Metal forming is a production technique which enhances economic use of engineering material by minimizing metal wastage that occurs in machining processes such as lathe turning and milling. This technique employs a press tool for mass production of parts that are dimensionally compatible. The press tool comprises the section that provides the force the press, and the tooling section the die. Investigation of stretch-forming conditions to produce a si dome in order to determine the opt...
ABSTRACT The quest for effective forecasting models to meet the ever growing electricity demand around the globe has heightened and taken a much challenging dimension that cuts across rural and urban communities in under-developed, developing and developed economies. Electric Load Forecasting which is the accurate prediction of both the magnitude and geographical distributions of electrical energy demand over the different periods of planning horizon has become a vital process in the planning...
ABSTRACT On the 27th June, 1995, the Engineering professionals, policy makers , representatives from various sectors and the Hon. Minister of Works and Housing - Major General Abdukarim Adisa gathered here to witness the launching of the NIGERIAN ASSOCIATION OF ENGINEERING CRAFTSMEN (NAEC). An Association that into existence in 1993 after the amended Decree 55/70 by 27/92 which empowered COREN to regulate engineering profession in Nigeria.
ABSTRACTA study was undertaken to developed a model that will be used to predict sugar and theby-products from sugar cane. The model developed from MATLAB was used to predictthe sugar, bagasse, filter cake and molasses yield from sugar cane. The predicted valuesfrom the model were compared to yield data obtained from the production of sugar canefrom the Savannah Sugar Company, Numan, Nigeria for 90 days. The analysis ofvariance (ANOVA) at p ≤ 0.01 was used to determine if there were signifi...
ABSTRACT Locating the position of a mobile user with a high degree of accuracy is a trending research interest. It holds the key to a breakthrough in many service challenges faced by operators in the wireless communication industry. With a success in this field, it will be possible for call rates in mobile phones to be charged based on the location a subscriber is calling from; fighting crimes and delivering emergency services through the mobile network’s ability to detect the caller’s po...
ABSTRACT In making a choice of solar Photovoltaic or diesel generator system as an alternative for power generation, life cycle costs (LCC) analysis are considered to be potentially important to such a decision. It incorporates all costs arising from owning, operating, maintaining and ultimately disposing of a project. In this study, a software computer program is developed to determine life cycle cost of solar Photovoltaic and diesel generator systems in Nigeria. The software is developed th...
