ABSTRACT The need for effective and efficient means of oil extraction has been a concern in recent time. Hence, this study aimed at the oil extraction from Moringa oleifera seeds using the Microwave-Assisted extraction method. The extraction process was modeled using Response Surface Methodology (RSM). Also, the evaluation of Moringa oleifera oil as a good feedstock for biodiesel production was carried out. Oil was extracted from the M. oleifera seed kernel using Microwave-Assisted meth...
Upgrade of wastewater treatment plants to improve nutrient removal.
Abstract The study focused on the impact of petroleum industrial degradation on agricultural produce in Ilaje Local Government of Ondo state. Four research questions were developed in conformity with the purpose of the study. The study adopted survey research design. Questionnaires were administered to elicit information on crop productivity, livestock productivity, forest and aquatic organisms and therefore the strategies to cope with the impact of petroleum industrial degradation. A total o...

(FO) as a case study. And consequently, drawup recommendations on how firms can improve their profitability in the sector.Methodology/Approach: Case study methodology is used to analys...
ABSTRACT Most people living in rural communities, have no access to good domestic water for consumption. The inhabitants depends on rain water, well water and sometimes surface water for consumption. Improper treatment of water gotten from these sources, can lead to the spread of water borne diseases, because, sometimes the water gotten from these sources are turbid. Although, some inhabitants use alum to treat the water so as to make the water clear. But excessive usage of alum to ...
Research and optimization of cooling of electronic components using heat sinks becomes increasingly important in modern industry. Numerical methods with experimental real world verification are the main tools to evaluate efficiency of heat sinks or heat sink systems. In this research, the physical problems associated with heat removal of electronic systems at different scales were studied. ABSTRACT Research and optimization of cooling of electronic components using heat sinks becomes increa...
ABSTRACT The rate at which energy is lost by human activities is enormous. There is need to work on how to generate more energy and minimize the usage of the generated energy. In an internal combustion engine, there is need to focus on gaining energy usage by using generated heat during combustion process. To reduce the energy usage, emission rate and improve the efficiency of four-stroke internal combustion spark ignition engine, the four-stroke internal combustion spark ignition engine is m...
This project- construction of a digital voltmeter seeks to utilize the microcontroller to build a digital voltmeter having better accuracy by utilizing a successive approximation analogue to digital converter ADC to measure the voltage (0 – 250V). Here, the working principal and components of this device are extensively explained. This Digital voltmeters (DVM) display the measured voltage using LCDs (Liquid Crystal Display) to display the result in a floating point format.
Abstract This temperature control fan can be controlled using a microcontroller when it detects a certain temperature that has been set. The purpose of this project is to prevent the waste of voltage usage when it is not hot enough for fan to be needed. The temperature control fan has three different speeds. Each speed will change according to a certain level of temperature that is set. This project is a combination of electric supply, fan, temperature senso...
ABSTRACT This project illustrates the use of an exergetic approach to analyze the performance of a vapor compression refrigeration system using a refrigerant solution of a nanoparticle (TiO2), mineral oil, and R410a (base refrigerant). Exergy investigation is a thermodynamics strategy which allows for the assessment and improvement of a refrigeration system in terms of efficiency and performance with basis placed on the 2nd law of thermodynamics. The primary objectives of this project are to ...
The major components of a gas turbine are compressor, combustors, turbine and generator. It operates by continuous drawing in fresh air into the compressor. The Air is then compressed to a high pressure in the compressor and discharge into the combustion. Here the air is missed with gas and burns continuous once ignited to increase its energy level at constant pressure. The high pressure and temperature combustion product enters an expansion turbine that converts the gas thermal energy into m...
The aim of this research is to determine the level of heavy metals contamination of agricultural soil and to reduce its concentration in the soil. Soil sampled at Inua Eyet Ikot, Mkpanak, Ibeno Local Government Area of Akwa Ibom State was analyzed to check for the initial heavy metal concentration of the soil. Poultry litter as a nutrient additive bearing microorganisms, bacteria and fungi was introduced to the soil to reduce the concentration of heavy metals. The sampled soil was mixed with ...
This study investigated the concentration of heavy metals in oil field produced water from Niger Delta, before and after treatment with locally sourced agricultural wastes. Two produced water samples were investigated for different metal ions such as; Lead, Nickel, Cadmium, Copper, Iron, Magnesium, Chromium, Zinc, Manganese, Calcium, Arsenic, Boron, Tin and Barium. The produced water samples were treated with four different adsorbents which are; Orange peels, Banana peels, Palm Kernel Fiber a...
ABSTRACT The purpose of this project work is to assess the strength of No-fines concrete pavement. No-Fines concrete is use in low traffic volume, pathways, sidewalk and parking lots. No-fines concrete is produced by using ordinary Portland cement, coarse aggregates, and water. In this study, Two (2) batches of no-fines concrete each with two different water – cement ratio 0.36 and 0.45 and cement – coarse aggregate 1:4 and 1:6 were prepared to find the mix that generated high compressive...
ABSTRACT The study was conducted to determine the effect of inclusion level of cowpea haulms and groundnut haulms on the growth performance and haematological parameters of Red sokoto goats. Nine goats were allocated to three dietary treatments which were formulated to contain 40% cowpea haulms, 40% groundnut haulms and 20% cowpea ː 20% groundnut inclusion. In a Completely Randomised Design (CRD). Each animal was fed 2.5% of the body weight of the experimental diet for a period of 12 weeks. ...
