ABSTRACT The aeromagnetic data of Ubiaja and illushi area that fall within latitude to and longitude to were interpreted qualitatively and quantitatively. The qualitative interpretation revealed that the area is intensely faulted with major anomalies (faults) trending in the northeast and southwest directions. Standard Euler deconvolution, source parameter imaging (SPI), spectral analysis and modelling (forward and inverse) methods were employed in the quantitative interpretation aimed at det...
ABSTRACT A simple and sensitive spectrophotometric method is described for the assay of the drugs; niacin, glibenclamide, erythromycin, thiamine and 4-aminobenzoic acid. The method is based on charge transfer complexation (CT) reaction of niacin, glibenclamide, erythromycin, thiamine and 4-aminobenzoic acid as n-electron donors with 2,3- dichloro-5,6-dicyno-1,4-benzoquinone(DDQ) as л-electron acceptor in methanol. Intensely coloured charge transfer complexes with niacin (reddish brown, lmax ...
ABSTRACT Dye sensitized solar cells (DSSCs) have been under extensive research. Since the color of the device can be easily varied by choosing different dyes and cells on flexible substrates, DSSCs are especially attractive for Building Integrated Photovoltaics (BIPV). The cell concept is believed to reduce the production costs and energy payback time to a large extent compared to standard silicon cells or other thin film cells. Dye sensitizer absorbs the incident sunlight and exploits the li...
ABSTRACT The roots of Dennettia tripetala and Milicia excelsa were analyzed for the presence of phytochemicals. Five different solvents, which include methanol, ethanol, ethyl acetate, butanol and water, were used for the extraction of the phytochemicals.The root of Dennettia tripetala contained alkaloids, terpenoids, flavonoids, saponins, phenols, steroids and glycosides in varying degrees of abundance in the different solvents with tannins not detected in all the solvents. Milicia excelsa c...
ABSTRACT Zinc Oxide (ZnO) nanowires with hexagonal structure were successfully synthesized by chemical bath deposition technique. The obtained nanowires were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), energy dispersive X-ray analysis (EDX) and spectrophotometer. The SEM micrographs revealed the morphology of ZnO nanowires with diameter between 170.3 and 481nm and showed that the pH of the bath solution, 8.1 is the optimized value to form ZnO nanowires with h...
ABSTRACT The study determined nutrient composition and organoleptic attributes of fresh and sundried carica papaya L pawpaw (Mbuer) and solanum macrocrpon L.garden egg (Mngishim) fruit soups consumed in Tiv communities of Benue State, Nigeria. Processing, preparation and utilization of fresh and sundried pawpaw and garden egg fruits for soup production information was obtained from focus group discussion (FGD).The recipes used for the work was based on t mean values after (FGD). The fruits we...
A comparative study was carried out on the remediation of brewery effluent (Beff) using derived adsorbent (Untreated and treated) and commercial activated carbon. Preliminary study and characterization of the brewery effluent, derived adsorbent and commercial activated carbon was recorded, with result showing physico-chemical properties of the effluent falls within, lower and higher than discharge limit outlined by NESREA and WHO. Result of the physico-chemical and instrumental character...
In a bid to further study the possibility of producing bioelectricity from microbial fuel cell (MFC), this study aims at increasing the production of bioelectricity in abattoir wastewater. The wastewater from abattoir was used to construct three different microbial fuel cells and they were connected in series. The voltage of electricity produced was recorded over the period of three days. The physiochemical property of the wastewater was determined. Also the microorganisms present in t...
Electricity supply in Nigeria has been a recurring decimal as huge amount of capital is involved. The aim of the study is to produce bioelectricity in a microbial fuel cell (MFC) from wastewaters. Wastewater from abattoir, fish pond, and stream were used to construct a microbial fuel cell and their physiochemical and microbiological properties were determined and the voltage of electricity produced was measured. Wastewaters were separately inoculated using pour plate to determine bacterial...
Abstract In this research work, sol-gel technique was used to grow some crystals of halide and chalcogenide compounds. These grown crystals were doped with locally produced dopants from bamboo, raffia and potash to see how they can affect the optical and structural properties of the crystals. Dopants were produced from local materials using top down approach where bulk materials (bamboo, potash and raffia) were whittled down through burning into carbon dioxide, water and residual ashes contai...

ABSTRACT Samples from Nturukpa leaf were processed using different processing methods. The first portion was oven dried at 50oC for 8 hours while the second portion was further divided into four parts and steam blanched at 100oC for 2, 4, 6 and 8 minutes, respectively. After blanching, each part was also oven dried at 50oC for 10 hours. Each dried sample was milled into flour. The third portion was wet milled (1:2 leaf: water, w/v), filtered and the filtrate was pasteurized at 65oC for 30 min...
ABSTRACT Undamaged and uninfested maize grains were hand picked, packaged in moisture proof package and disinfested in the deep freezer for 96 hours. Thirty six sets (500g per set) of disinfested maize were weighed into prepared containers. Each set of maize was infested with 200 live maize weevils (Sitophilus zeamais). The weevils were reared on whole maize at room temperature inside a plastic bucket covered with muslin cloth. Graded levels (0 to 10%) of coarsely ground spices Monodora myris...
ABSTRACT Mathematical Models describing the variations in the volume of the system, concentration of reactant (s) yet to react, temperature of the system, and the temperature of the cooling jacket over time in a non-isothermal CSTR that handles a simple, irreversible, first order or second order exothermic reaction in liquid phase were formulated. This work is with a particular reference to the synthesis of propylene from cyclopropane and that of cumene (isopropyl benzene) from benzene and pr...
ABSTRACT This project is concerned with the development of an Enhanced Information System for the Self-sustenance activities of Tertiary Institutions. Entrepreneurial activities are becoming common place in Nigerian institutions of higher learning, in their bid to raise funds in the face of dwindling government funding. The existing information systems are not sufficiently equipped to aid the managements of these institutions in the effective running of the fund generating ventures. The datab...
