Abstract In the United Republic of Tanzania (URT), all environmental issues related to the mining industry are regulated according to two principle Acts: The Mining Act and the Environmental Management Act, and their respective regulations. The current acts were enacted in 2010 and 2004 respectively. Mineral exploration (that includes all on-site activities performed before a mining project is declared feasible) projects in URT appears to be “unforgotten phenomena” in the two major legis...
Abstract This research work investigated the effect of current density, bath concentration, bath soIution volume and electroplating time on nickel electroplating of low carbon steel. Varying voltage between 0.3 and 0.8 V, bath concentration between 0.27 g/cm3 (0.79 rno~ddan d 0.35 glcm3 (1.02 mo~dmp, electropfig time between 1Q and 30 minutes and bath solution volume between 200 and 700 cm3, the effect of these process variables on electroplating was studied. The temperature was kept in confo...
ABSTRACT An assessment of farm transportation system to ascertain the availability of transportation for the evacuation of farm produce was undertaken in Osun and Oyo states of Nigeria employing printed questionnaires and personal communication as means of information collection. 20% of the farmers reside at between one and three km from their farms while for the remaining 80%, it ranges from four to 16 km. 17.6% of the farmers travel between one and three km to sell their produce while for t...
Abstract The study was carried out to identify the entrepreneurial skills required by Internally Displaced Persons (IDPs) in quail production for sustainable living in North-Central Nigeria. Specifically, the study identified skills in planning, rearing and marketing of quail and its products in the area of study. To achieve these specific objectives, three research questions and three null hypotheses were formulated to guide the study. The study adopted descriptive survey research design. T...
ABSTRACT This work was designed to determine the ways of enhancing food production through organic agriculture among farmers. Five research questions and five null hypotheses guided the study. A survey research design was adopted for the study.The study was carried out in northern zone of Cross River State, Nigeria. The population for the study was 230 comprising 205 registered crop farmers and 25 Agricultural Development Programme (ADP) extension agents from Ogoja Agricultural Zone respecti...
Abstract The study was carried out to determine the effects of Moringa oleifera leaf powder additive on the growth of layers, egg production and nutritive value of eggs. Specifically, the study sought to determine among others the effects of Moringa oleifera leaf powder fortified feeds and control feed on the growth of layers, effects of different inclusion rates of Moringa oleifera leaf powder on the growth of layers, effects of Moringa oleifera leaf powder fortified feeds and control feed ...

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.
