ABSTRACT Gravitational drip irrigation system was developed using available materials. The system consisting of 4.0 Ilhr Netafim pressure-compensating emitters was used to irrigate 0.0015 ha of land where sweet com was planted under variable water applications in a randomised complete block design with three treatments. Treatment one (WI) received water once per week, treatment two (W2) received water twice per week, while third treatment (W3) received water thrice per week. WI received 229mm...
ABSTRACT The varying shapes and sizes of cassava tubers have made cassava peeling to one of the major problems in the mechanisation of cassava processing. A cassava peeling machine was designed and constructed. The design parameters include a power requirement of 0.36hp, belt tensions of 349.7 and 1807.5N and shaft diameter of 35mm. Its main component is a peeling chamber, which consists of two perforated drums rotating in the opposite direction. The machine had an average capacity of of 44.5...
ABSTRACT;, This paper presents an important research 1001 in operations research as it applie~'to a particular structure of theinunicritcria assignment problem. The paper addresses the problem of effectiveness of feasible solutions of a multicritcria assignment problem and this was done in two steps. In the first step. we determine whether or not a given feasible solution of a n-ulticriteria assignment problem is a real efficient one. In the second step. if the feasible solution is not real e...
ABSTRACT Some physical and mechanical properties of small diameter poles obtained from guava (Psidium guajava L) tree branches in relation to their potential use for truss fabrication were determined. The average green moisture content of wood from five replicate samples of debarked tree branches was 84%. The wood samples were naturally resistant to termite attack with and without the bark on. The mean oven-dry density of the wood samples was 674 kg/m3. This puts it in the density category of...
Poor finishing and aesthetics capabilities of metal fabrication companies in Nigeria have been identified as a major cause of the poor acceptance of locally fabricated metal products. This study was aimed at assessing some finishing capabilities of Nigerian companies.
Abstract Heptanes plus fractions have strong effects on the physical properties and phase behaviour of petroleum fluids. It is therefore very important to properly characterize plus fractions. A step to achieving improved characterization is to obtain more realistic molecular weights. Most of the current methods of heptanes plus characterization assume their molecular weights are accurate. However, what is commonly measured in the laboratory is the molecular weight of the complete fluid; the ...

ABSTRACT This work is aimed at determining the feasibility of manufacturing automobile batteries on a small scale ·Ievel. It involves an economic evaluation directed at the typical 12V, 60Ah car battery. A process analysis was done with a view to determining the scalability of the processes. A review of relevant literature gives insights on the product structure and workings, material interactions, process requirements and the various manufacturing strategies and their respective benefits. T...
ABSTRACT The computer-aided software developed in this research work is used in designing cam systems by generating various follower motions and cam profiles. It is highly suited for extensive dynamics, kinematics and geometric design analysis based on some inherent features that are unique. The plate cam with either flat-face or roller followers can be designed. Most of the standard and acceptable cam functions are included such as double harmonic, modified trapezoidal, cycloid, 4-5-6 polyno...
ABSTRACT This study was designed to determine the effects of challenge-based and activity-based learning approaches on technical college students’ achievement, interest and retention in woodwork technology. A pre-test, post-test, non-equivalent control group, quasi-experimental research design was adopted. The study constituted a total number of 122 subjects, 63 for the Challenge based learning, while 59 were for the activity-based learning. Eight research questions and twelve null hypothe...
Abstract Plate washing is a daily activity across the globe which involves a lot of energy to accomplish manually or mechanically. The objective of this work is to design and fabricate a dish washing machine that is efficient and easy to operate. Stainless steel and mild steel was used for the construction of the machine considering their availability, cost reduction and corrosion resistance. The motor used a power of 0.75hp (559.5 W), voltage of 240V and a speed of rotation of “1200 r.p.m�...
Abstract Subsurface oil viscosity data are usually 110t readily available for most reservoirs, as they are expensive to acquire. On the other hand, surface oil viscosity is routinely measured and therefore readily available for all producing wells. A method has been developed for converting the surface viscosity to reservoir viscosity data, using SPDC's "Field A" as a case study. Surface oil viscosity data from all producing wells in "Field A" where collected from SPDC-West Production Chemist...
