In this research, Sandbox (Hura crepitans) seed oil is used as feedstock extracted by solvent extraction using N- hexane as solvent. The study evaluates properties of the oil for it suitability in biodiesel production, biodiesel yields as it is affected by the reacting conditions such as methano-oil molar ratio, reaction temperature, catalyst concentration and reaction time, the reaction conditions are optimized using a two-step four factor factorial design. Results indicate that the feedstock is suitable for biodiesel production, catalyst concentration and reaction times interaction are the important factors that has greater effect on the yield of ethyl ester. The optimum yield condition for Sandbox (Hura crepitans) were 0.2wt/wt molar ratio, 30oC temperature, 0.4wt% catalyst concentration and 60 min reaction time yielding 93% ethyl ester (biodiesel), and all the measured properties of Sandbox (Hura crepitans) of biodiesel met with ASTM6751 standard exception of high polarization rate and slightly high viscosity that can be normalize by appropriate blending. The result showed that only molar ratio showed a negative effect on the reaction. Hence adhering to the standards for high quality biodiesel and economically cheap production process.

Abstract: Sesame seed candy is a type of candy that is made by combining sesame seeds and either sugar or honey. These ingredients are then formed into a bar or ball shape through pressing. This study aimed to investigate the effect of storage duration and influence of three packaging material on the quality of value-added sesame seed candy. Sesame seed candy samples were packaged in different materials, including Aluminum Foil Laminated Pouches (AFLP), Low Density Poly Ethylene (LDPE, 400 gauges), High Density Poly Ethylene (HDPE, 700 gauges) and stored for 60 days at room temperature. Proximate analysis, sensory analysis and microbial analysis of the samples were carried out every 5 days. The storability analysis of the sesame seed candies shows that both storage duration and packaging material has influence on the total plate count with p-value less than 0.0001. The longer the duration of storage the more the growth of bacteria. The mold count is only affected by the packaging material. Based on the experimental result, aluminum foil laminated pouches are the best material to package the candy and it will still maintain some of its vital qualities over a period of time.

Authors: Durojaiye, Abdulwahab Ismail; Olorunsogo, Samuel Tunde; Adejumo, Bolanle Adenike; Babawuya, Alkali; Muhamad, Ida Idayu Abstract: Dietary mineral contents are essential nutritional elements with utmost importance which greatly contributes to both human and animal wellbeing to maintain sound health. It also assists plants to flourish adequately especially during growth. Deficiency in any of the essential micronutrients can result to life-threatening circumstances. In this study, essential elements (Ca, Fe, K, Na and Se) of two varieties of rice (NERICA 1 and FARO 59), two varieties of beans (pod borer resistant (PBR) and IT07K-318-33), plantain (Musa paradisiaca spp), Marabel irish potatoes (Solanum tuberosum L.), beef (Bos taurus) and chicken (Gallus gallus domesticus) commonly consumed in various forms were evaluatedto ensure seamless supervise machine learning operation for the calibration of a non-destructive equipment. Association of official analytical chemist (AOAC) standard experimental procedure was adopted and atomic absorption spectrophotometer (AAS) was used to obtain reference data of mineral contents for both raw and cooked samples of the selected food products. The experimental results revealed high values of 18.72mg/kg, 2.56mg/kg, 30.92mg/kg, 19.94mg/kg and 1.64mg/kg in Ca, Fe, K, Na and Se respectively across the food combinations. The result trend was observed with lowest spread of mineral values of 1.57mg/kg, 0.02mg/kg, 2.54mg/kg, 0.88mg/kg and 0.04mg/kg in the above trace elements sequence respectively. Generally, the results cascade within the daily acceptable limit for consumption as prescribed by food regulatory agencies and hence, fit and reliable for use as reference data for machine learning training for a non-destructive tool.

S.; Jimoh, Y. A; Yusuf, I. T.; Adeleke, O. O.; Balarebe, F.; Shehu, M. Abstract: This research work investigated the improvement of the properties of weak lateritic soil using sawdust ash (SDA) as the stabilizing agent. Preliminary tests such as specific gravity, moisture content, Atterberg limits, particle size distribution, Geotechnical strength tests (compaction and unconfined compressive strength (UCS) tests) were first carried out to determine the initial properties of the weak lateritic soil without the stabilizer. Based on the results of these tests, the soil was classified according to AASHTO soil classification system as A-7-5 soil which is a poor soil. The soil was then stabilized, consistency tests and strength tests such as, compaction tests and unconfined compressive strength (UCS) were performed on the soil by the addition of 2%, 4%, 6%, 8% and 10% sawdust ash to 98%, 96%, 94%, 92% and 90% by weight of the lateritic soil respectively. The results showed that sawdust ash improved the geotechnical properties of the weak lateritic soil. The optimum improvement in the properties of weak lateritic soil by stabilization using SDA is at 4% replacement. At this percentage of stabilization, the soil was classified as an A-5 soil (fair silty soil), the liquid limit decreased by 4.96%, the plastic limit decreased by 1.50%, the plastic index decreased by 15.74%, the maximum Dry Density is seen to decrease by 3.7%, the Optimum Moisture content (OMC), increased by 11.11% and the Unconfined Compression Strength increased by 26.9%. Sawdust ash is therefore found to be an effective stabilizer for lateritic soils. Tue, 01 Jan 2019 00:00:00 GMT http://irepo.futminna.edu.ng:8080/jspui/handle/123456789/31427 2019-01-01T00:00:00Z
