ABSTRACT The earth‟s surface is affected by three main types of radiation from the sun: global solar (or total), beam (or direct), and longwave (or indirect) radiation. Global solar radiation is composed of direct and indirect radiation. Approximately 99% of the total radiation from the sun that reaches the earth is beam radiation, which has a wavelength range of 0.29 to 3.9 μm and is not subjected to interference from any interspatial matter. The remaining 1% is longwave radiation, which ...
ABSTRACT Malaria has played an important role in the history of mankind because it is a constant threat to human health and it affects economic development and growth in areas highly affected by the disease. The disease is more lethal in children 0-5years, pregnant women and in people from non-malaria endemic areas. An estimated 247 million cases, nearly a million deaths, mostly in children less than five years old were attributed to malaria (WHO, 2008a). Nigeria accounts for a quarter of all...
Abstract this page contributes to the debate on the role of the informal sector in solid waste management by examining the effectiveness of informal sector solid waste management practice in transforming waste into nonwaste in the city of gweru in zimbabwe.
ABSTRACT Every organisation tries to operate in a dynamic environment; as a result, no organisation intends to stay the same. Thus the organisation’s survival depends on how fast and well they react and respond to change. The changes are expected to come from both business and technological perspectives. Change is implored and implemented through different approaches, such as Enterprise Architecture (EA). Organisations adopt EA as a way to map and describe organisational structure, business...
ABSTRACT Joloo is a formulation extracted from seven medicinal plants used in folk medicine practice for the management and treatment of breast cancer and some other health malaise in southwestern Nigeria. The study evaluates some of its traditionally acclaimed pharmacological properties in mice and rats as well as the safety of Joloo. Three toxicity levels of study which included acute, subchronic and chronic toxicity were undertaken to evaluate the extract. Joloo was prepared using plants i...
ABSTRACT This project addresses the effects of increase in fines contents on the geotechnical properties of sandy soils and the roles the fines play in slope instability in Nsukka, Enugu state in Nigeria. Field investigation revealed that the major landslides and gully erosion sites in south eastern Nigeria are localized within areas where these sandy soils are present. Geotechnical investigation of these sandy soils was carried out to assess their importance in the numerous geohazards in the...
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 simulat...
