ABSTRACT Optimization of hatchery production processes was carried out using the Monte Carlo method. In the economics. of engineering decisions with the objective of the investor identifying an optimum solution. an investor chooses his or her optimal solution from the set of scenarios that offer maximum expected return for varying levels of risk. Outcomes associated with these random numbers are then analysed to determine the likely results and the associated risks. Taking a major day old h...
INTRODUCTION Excessive water production as result of coning and cresting has been a serious problem in the oil and gas industry. Coning or cresting are used to describe the mechanism underlying the upward movement of water and/or the downward movement of gas into the perforations of a producing well. Efforts have been directed at understanding the mechanism of water coning/cresting in vertical and horizontal wells. These efforts have led to the development of correlations for estimating cri...
ABSTRACT Dark green leafy vegetables (DGLV) such as Amaranthus spp are known to be good sources of beta-carotene, a pro-vitamin A carotenoid and a highly potent anti-oxidant. Anti-oxidants terminate chain reactions, prevent recurrence and also prevent the formation of unstable oxygen which otherwise can initiates a chain reaction that propagates to cancerous cell. Cancer is strongly attributed to poor diet as well as lack of exercise. New cancer cases are diagnosed daily, leading to a project...
ABSTRACT Extracts and powders produced from the leaves of two indigenous vegetables – ‘atama’ (Heinsia crinata) and ‘uchakoro’ (Vitex doniana) were evaluated. Four groups of processes were applied on the vegetables to obtain the samples: blanching, oven drying and milling; oven drying and milling; steam blanching, wet-milling, filtration, and fermentation; fermentation, wet-milling and filtration. After, a preliminary study to evaluate the antinutritional factors at different interv...
ABSTRACT Biomass is organic materials that are made from plants and animals. Biomass stored alot of energy from the sun. Biomass is renewable sources of energy which can grow more such as trees and crops, and waste always exist. Example of this biomass may include wood, forage crops, manure and some garbage and alcohol fuels. The usable forms of energy suc...
ABSTRACT This work evaluates the effects of climate change on cowpea production among small-scale farmers in this regard Katagum Local Government Area of Bauchi state, Nigeria. The study had (4) research objectives and (4) research questions raised from the objectives. Multi-stage sampling technique was used to select respondents from the study area using five (5) districts as sample size; Madara, Buskuri, Madangala, Azare, Bulkachuwa. The method used in the collection of the data was questio...
ABSTRACT The project dealt on the production of yam flour from yam chips. The yams were peeled and washed, 100grams samples coded sample A to G were subjected to two different drying conditions. Some were dried using the sun drying method while the others were dried through oven drying method kept at constant temperature of 500C, sodium bi-carbonate was added to some of the samples, all these were done to obtain a flour with the best colour and texture quality. From the results obtained, it w...
ABSTRACT Hydrocarbon production in the petroleum industry is often constrained by reservoir heterogeneity, deliverability and capacity of surface facilities, also optimization technique in the petroleum industry requires execution of several iterative runs by comparing various solutions until an optimum or satisfactory solution is found. In this study a comparative economic analysis to aid the optimization of petroleum production was done. Two key variables, tubing sizes and choke sizes were...
INTRODUCTIONIn order to reverse this unhealthy trend, and underpin Nigeria’s global competitiveness in the international market, it has become imperative to diversify the economy and broaden the revenue base within and away from crude oil export. As a result, the government must embark on a deliberate, determined and systematic plan to aggressively expand and promote non-oil exports. This has become even more compelling considering the volatility in the global oil market and its topsy-turvy...
ABSTRACT The production of the soap was carried out using all the necessary equipments like the reactor, mould, stirrer, hygrometer guage etc. and all the required reagents for soap production in correct proportion. In the production, palm kernel oil (P.K.O) was used instead of tallow or grease. This was because soap produced from grease or tallow tends to dissolve slowly at room temperature, whereas, soap of palm kernel oil product gives a quicker lather which is relatively suitable. Diff...
ABSTRACT Mangala Village Land Forest Reserve is a productive forest under Community Based Forest Management being managed by the Mbangala Village Council. The forest reserve was established in 2010, at Songwe District in Songwe Region. Sustainable charcoal production in Songwe District has not received a systematic research assessment. To what extent the so called sustainable charcoal production adheres to sustainability principle is not clear. The aim of this study was to assess charcoal pr...
ABSTRACT A study carried out to evaluate the growth performance and economic benefit of Nile tilapia and Chinese cabbage under integration system. Nine ponds and twelve vegetable plots were used. Three ponds treated with feed only (T1), another three ponds with chicken manure only (T2) and the last three ponds with chicken manure and supplementary feed (T3). Fish with an average weight of 1.2 g were stocked at rate of 5 fingrlings/m2 in each pond. Fish were fed at 5% of their body weight and...
ABSTRACT Spinach (Spinacia oleracea) is a low growing fleshly leaved annual plant that can be used as a vegetable and or to treat a variety of diseases. This study aimed at comparing the effectiveness of cow, chicken and pig manure on the plant height, leaf number, leaf length as well as root length of spinach. An experiment was conducted in a greenhouse at Africa University between the months of June and July 2018. The experiment was a randomised complete block design (RCBD) with chicken ma...
ABSTRACTS A ten weeks feeding trial was carried out in order to examine the effect of including different types of lipids in the diets fed to African catfish fingerlings (Clarias gariepinus) on their growth performance and serum biochemistry. A total of one hundred (100) African catfish fingerlings with weight range of 129-130g per one 50litres circular plastic bowl containing ten (10) fingerlings were randomly allotted to five (5) experimental diets (CP: 40%) on 3% inclusion levels of differ...
ABSTRACT Soilless farming of vegetables in greenhouse has become a profitable venture in some parts of the world. A high degree of competence in engineering skills, irrigation techniques and cost reduction is required for its successful operation. In Nigeria, the potential of soilless farming in greenhouses has not received adequate attention. The use of soilless media and appropriate irrigation system to produce marketable tomato in a greenhouse were investigated. Roma VF variety of tomato...
