This study utilized fractal disk dimension characterization to investigate the system response of a nonlinear, harmonically driven pendulum of mass, m (or weight. W) and length I over a well-defined parameter plane of excitation amplitude versus damping factor. The system response was simulated at three drive frequencies (symbol,*) of 1/3, 2/3 and 313. A Runge-Kutta fourth order algorithm, coded in FORTRAN programming language was used to simulate the System response over a 101 by 101 para...
In order to monitor and control the properties of drilling fluids, measurements are routinely made at the surface. However. these surface measurements may not be representative of down-hole properties where the desired functions of hole cleaning and other related issues are critical to the success of the drilling operations. Consequently, it is important to make necessary adjustments of the fluid properties obtained at ambient conditions to give estimate of properties at high tempera...
In this work, modifications have been done on a prototype pneumatic separator to improve its efficiency. The effects of the modifications were studied by carrying out performance test analyses on the two blowers and reciprocating sieve mechanism which make up the critical components of the separating machine. The variations in the feed weights of the sieve were analysed to determine the best and most effective screening process. Also, the best and least tilt angles of the blowers were co...
Presently, Nigeria is among the nations that are technically unable to meet their food supply needs from rain-fed production at a low level of inputs and appear likely to remain so even at intermediate levels of inputs at some point’s time between 2000 and 2025 (FAO 2002). For the rural areas of semi-arid Northern Nigeria, which experiences significant climatic and anthropogenic changes that have exacerbated food insecurity in the region, floodplain agriculture is critical to the survival...
ABSTRACT Control of mosquitoes is something of utmost importance in the present day with rising number of mosquito borne illnesses. The effect of mosquito bites cannot be overlooked considering how many deaths it has caused over the years. Specialty products like mosquito repellent used to combat mosquitoes are required but most of the repellants available use chemical means to repel or kill the mosquitoes which in a long run also becomes detrimental to ourselves and the environment. This pr...
Abstract This study investigated how farmers in Southwest Nigeria use mobile phones for agribusiness, the benefits of the use of mobile phones, and the challenges farmers face using the device. Driven by theory of information and communication technology for development, this study adopted survey and focus group discussion (FGD) methods. Stratified, random, purposive and convenience sampling techniques were employed to select the sample. A questionnaire and FGD guide were used to collect dat...
ABSTRACT The main purpose of the study was to assess Competency Based Training on the skills acquisition of Electrical/Electronic Engineering Students in Ghana, using Cape Coast Technical University as a case study. The researcher used descriptive research design for the study. The study adopted the mixed approach which made used of both quantitative and qualitative approaches. The study population was made up of all Electrical/Electronic Engineering Students, Lecturers, Laboratory Technicia...
ABSTRACT Maintenance is important to the success and continuity of firms, particularly in the changing society as ours. The effectiveness and the survival of organizations are largely enhanced by the ability of management to ensure that there is functional equipment, lands and buildings, infrastructure and fixtures. In the manufacturing setup, there is wear and tear of machines and equipment in the periods of usage that require sufficient maintenance to enhance their useful life. This ensure...
ABSTRACT This research investigated the performance of rural and urban petty traders in AfigyaKwabre District. A total of two hundred (200) questionnaires were administered in the study area but one hundred and ninety-three (193) responses were received. Descriptive statistics was employed to describe the demographic characteristics, social capital of petty traders and their customers, the roles they play and challenges associated with petty trading. The findings revealed that demographic c...
In certain parts of the country and the globe, a consistent and steady supply of power is still scarce and inaccessible. In such places, this work will support refrigeration of nourishments, food, medications, etc... The results of such empirical research to assess the efficiency of household refrigerators is discussed in this article where melted petroleum gas (LPG) which is locally accessible comprising of 24.4% propane, 56.4% butane, and 17.2% isobutene varying from company to comp...

ABSTRACT This project is designed to determine households’ access to safe water supply in Ootunja, Ikole-Ekiti, in terms of quality and quantity as the importance of improved water supply to human health cannot be over emphasized. However, safe/improve water supply to most Nigerian cities is still inadequate. In the study area the relationship between water quality, the degree of water source protection and quantity. This aim was achieved through the use of well-structured questionnaire in...
ABSTRACT This study was carried out to examine the techniques and technologies for cassava processing in Eliki Slate, to identify the various products from cassava in the study area, to generate ways of improving the techniques and technologies, and to recognize the constraints to processing and marketing of cassava products. The study made use of structured questionnaires, oral interviews and focused group discussions to select a sample size of 120 respondents.The population under study was...
ABSTRACT Water released from ponds has greater concentrations of nutrients, organic matter and suspended solids. This study investigated the physical, chemical and biological characteristics of fish pond waste water harvested from a source which served as the control, three different ponds and at the point of discharge in Afe Babalola University Ado Ekiti (ABUAD) farm, Ekiti State. The samples were collected in 50 ml capacity polypropylene containers. Parameters investigated include temperat...
ABSTRACT This research project investigates the geotechnical characteristics of soils in Federal University Oye Ekiti, lkole campus. In this research project, disturbed soil samples were obtained from five labelled TP 1, TP 2, TP 3, TP 4, TP 5 at different locations and at various intervals along the university and were taken to laboratory for relevant soil engineering tests. The relevant soil tests include; particle size analysis, consistency limits (liquid, plastic, and shrinkage limits), n...
