    Determination of the Suitability of Urine as Substrate in a Power Generating Soil Microbial Fuel Cell
    (2016-08-18) Simeon, Meshack Imologie; Raji O. A.; Musa J. J.; Kuti I.
    Urine has been identified as a suitable substrate in Microbial Fuel Cells (MFCs). However, its possible utilization in a soil-based Membrane-less Single Chamber Microbial Fuel Cell (MSCMFC) has, hitherto, not been reported. This study used the mud-watt MFC vessel inoculated with mud prepared from topsoil, and was operated across seven external loads for 19 days (456 hours) without adding any substrate to the soil. Urine was fed into the cell in four durations of time, after the MFC output stabilized. For comparison, a fresh setup (control MFC) was made and operated under the same conditions of temperature (27+3°C), but without the addition of urine. The performances of the MFCs were examined over seven external loads of resistance: 4670 , 2190 , 1000 , 470 , 220 , 100 , and 47 . The Urine-treated MFC and the control MFC both produced an initial peak power output of 5.62μW. Both MFCs produced close values of power outputs up to the point of adding urine. At the final stage, the peak power output of the MFC treated with urine was 246.77μW; whereas the corresponding values for the control MFC were 0.007μW. This study showed that fresh (untreated) human urine can be successfully utilized as fuel in a soil-based MFC for the production of electrical energy for varied external loads.

    Design, Fabrication and Testing of a Tractor Drawn Soybean Planter
    (FUW Trends in Science & Technology Journal, 2017-04) Agidi, Gbabo; Andrew, I.; Simeon, Meshack Imologie
    A tractor drawn Soybean drum planter was designed, fabricated and tested in the DESFABENG Company Limited, Bida, Niger State. The project was undertaken because most of the imported planters usually have maintenance and repair problems in addition to high costs of procurement that are not affordable to an average farmer. The major components of the developed planter are three drums with predetermined hole sizes at the exterior ends, a central rectangular shaft, spring soil openers, roller soil coverers, tractor hitching points, two wheels, and power transmission mechanism, and a frame. All these components were fabricated with locally available materials. Using three test speeds, the planter was preliminarily assessed for seed rate, soil opening, covering, and germination efficiencies. Results obtained indicate that desirable seed rate values of 47.7 and 61.2 kg/ha were observed for tractor/implement speeds of 20 and 16 km/hr, respectively. The highest germination efficiency of the planter was 81.3% at a tractor/implement speed of 16 km/hr with a corresponding soil opening efficiency of 94%.

    Optimisation Of The Production Parameters Of Delonix Regia Methyl Ester Using Box Behnken Design
    (INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH, 2019-09-09) Adejumo, B. A.; Agboola, J. B.; Orhevba, B. A.; Obasa, P. A.; Simeon, Meshack Imologie
    The optimisation of the production parameters of Delonix regia ester was carried out to establish the parameters for the production of optimum methyl ester yield from Delonix regia seed oil. The effects of reaction temperature, reaction time, alcohol: oil molar ratio, and catalyst concentration as well as their interaction effects on the yield of methyl ester, were investigated using the response surface methodology Box-Behnken design. Data obtained were analyzed statistically using Design expect 9.0 statistical package to determine the response model, surface respond anal ysis of variance (ANOVA). The data collected from optimization of the reaction process was fitted to a model. The results showe d that the percentage yield in term of reaction temperature, time, molar ratio, concentration and interaction terms of reaction tem perature and reaction time were significant (p ≤ 0.05) while the lack of fit F value for the Delonix regia methyl ester yield response showed that it was not significant ( p ≤ 0.05) relative to the pure error. This indicates that all the models predicted for methyl ester yield response were adequate. Regression models for data on response methyl ester yield were significant ( p ≤ 0.05) with a satisfactory R 2 value of 0.829. The boundaries of the design intergalactic of methyl ester yield have the lowest value at 72 % within the process range of 40 0 C to 56 0 C for Temperature, 30 to 53 minutes for Reaction time, for all production processes while the highest of 90.21 % with the process boundary range of 55 to 60 0 C for A: Temperature, 40 to 60 minutes reaction ti me. The optimization solution gave the process conditions for each process factor at the highest desirability prediction of 0.642 as the best reaction temperature of 53.20 0 C and the reaction time of 60 minutes, alcohol: oil molar ratio of 2:1, and catalyst concentration of 0.69% when the set goal is based on the physic thermal properties of produced methyl ester.
