ABSTRACT There has been growing need to characterize the fluid flow through a simplified model such as random walk dynamics.
ABSTRACT This paper discusses how normal, lognormal, and log pearson type 3 distributions were investigated as distributions for modelling at site annual maximum flood flows using the Hazen, Weibull, and California plotting positions at Ogun-Oshun river basin in Nigeria.
ABSTRACT The critical energy situation in Nigeria suggests the need to study energy and exergy utilization in households, with the aim of pinpointing areas of waste and suggesting alternative measures for effective and efficient utilization of scarce resource.
Abstract Nanocomposite hydrogels of poly-n-isopropyl were prepared by incorporating gold and magnetite nanoparticles. The nanocomposite-based hydrogels formed were geometrical, ~7.3 mm in diameter and 5 mm thick (in the swollen state). Morphological analysis was characterized by a scanning electron microscope. Drug-loaded hydrogels were subjected to laser heating at 1 W, 1.5 W and 2 W for 20 min in each laser cycle. The metabolic activities of the cells were analysed. The photothermal convers...
Abstract Road construction typically confers significant benefits on the population the road serves. A recent rapid growth of urban residential areas in Ghana has necessitated the construction and rehabilitation of the roads linking these urban areas to major commercial towns in the country. The Kwabenya (Abuom) to Kitase area, straddling Ghana’s Eastern and Greater Accra regions, is a typical example. Using both primary and secondary data sources, the research reveals that agricultural pro...
Abstract This paper presents a recent study on recycling poly-ethylene-tetraphylate (PET), known as plastic waste material in Ghana, to wealth. Composites were produced by heating aggregates together with shredded PET plastic waste material, while bitumen was added to the plasticcoated aggregates. The composites produced were reinforced with 4.5 wt%, 9.0 wt%, 13.6 wt%, and 18.0 wt% PET. Mechanical properties of the fabricated composite samples were studied with a Universal testing machine for...
ABSTRACT The One Laptop Per Child project has succeeded in developing a novel computer that is tailored to the particular needs of the developing world. The use of this example of a modern computer systems design challenge can be a valuable case study as a teaching tool in computer science. The OLPC laptop is a multiple-purpose computer that is rugged, low-cost, low-power, mesh networked, and inexpensive. An overview of the technology in the laptops is given, as well as curricula suggestions ...
ABSTRACT Determining the filtration properties of a mud system requires that experiments be run for both the standard API and the high temperature pressure tests at intervals throughout the duration of drilling an oil well.
ABSTRACT The effect of climate change in recent times has necessitated the need for a controlled environment for the cultivation of many crops which where hitherto cultivated under natural tropical conditions.
ABSTRACT Both Engineering students and praticising engineers are involved in the design and analysis associated with fluid mechanics and thermodynamic problems.
ABSTRACT The plastic extruder system is an important process in the solid waste recycling system.
ABSTRACT Grinding is one of the most Important finishing operations and it is very useful in our automobile industries.
ABSTRACT Reliability indices are considered to be reasonable and logic way to judge the performance of an electric power system.
ABSTRACT The development of a framework for the local production of low-cost injection moulds, using inputs and technical skills available within a typical Nigerian city is the focus of this study.
ABSTRACT Abundant and economical energy is the life blood of modern civilization.
