    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%.

    DEVELOPMENT OF AN ANDROID BASED MOBILE APPLICATION FOR THE DESIGN AND DETAILING OF ISOLATED PAD FOUNDATIONS ACCORDING TO EUROCODE 2
    (i-manager’s Journal on Mobile Applications & Technologies, 2019) Yusuf, Abdulazeez; Isiaka, I.; Abubakar, Mahmud; Aminulai, H. O.; Abdullahi, Aliyu; Alayande, T. A.
    In a building construction project, it is the responsibility of the structural engineer to come up with a complete design of all structural elements. When this is done manually it is tasking, time consuming, and produces errors with inconsistent results. However, the design can be done using computer software, but this also comes with some downside; it is expensive and complex to use. Thus, this research developed an android based mobile application for the design of pad foundations to Eurocode 2 to put these challenges in check when designing pad footings. The mobile application designs isolated Axially loaded-only and Axially loaded with bending pad footing to Eurocode 2 accurately, with consistent results and in a timely manner. The application was tested using typical test parameters and results are compared to the manual computations. There was no significant difference in the steel sections provided for both methods. All checks that must be satisfactory in design were all checked and found to be satisfactory.

    Design and Performance Evaluation of a Portable Solar Water Heater
    (Journal of Digital Innovations & Contemporary Research in Science, Engineering & Technology, 2022-03-20) Bori Ige; Uwah, E. J.; Bako, .S.; Okegbile, O. J.; Ayo, S. A.
    This paper presents design and performance evaluation of a solar water heater (SWH) using thermosyphon principles, thereby eliminating the use of electric water pump and reducing the cost of the entire system. There are many phenomena encouraging the application of solar water heating technology such as; electric power outage, high fuel price, rapid urbanization, low cost of installations, and governmental intervention. Therefore, there is need to encourage innovation in the field of solar technology. The design of this system was done using relevant equations to obtain the required dimensions of the various components of the system. The materials were selected based on design calculations, machining, availability and material cost. During the testing process, the first three days of testing the highest outlet temperature recorded was 650C. For the last three days of testing during the dry season, the highest outlet temperature recorded was 79.3 0C. The results showed that the system performs better during the dry season when the irradiance levels are higher. The highest irradiance recorded was 940 W/m2 on the sixth day of testing. The highest efficiency recorded from the system was 68.19% on the fourth day of testing. It is hereby recommended that, sensor and a flow meter should be installed for determining water level and for easy identification of flow rate.
