    Design and Fabrication of an Adjustable Sitting Inclinations Spinal Cord Rehabilitation Chair
    (De Gruyter, 2016-11-22) K. R. Ajao; T. Yahaya; H. A. Ajimotokan; Adekunle Akanni Adeleke; M. Bello; O. Ojegbenro
    The adjustable sitting inclination rehabilitation chair was fabricated with mild steel and soft upholstered fabric was used for the overlay on the seat, headrest and armrest. The components were coupled with a linear actuator at the upper frame for the reclining of the backrest about it axis. The wheels are located outboard of the seat of the chair to enhance stability while foot rest supports the posterior weight of the users. The narrow seat allows free movement of the leg when the user is seated. Sitting inclinations of 120 and 135° protect the spine disc from compression and proffer more comfort for the users than other angles experimented. The adjustable sitting inclination SCRC is simple and affordable for low-income people with Spinal cord injury, especially for those in developing countries in order to support other therapies for their recovery processes.

    Exergy Analysis of a Multiple Reflector Solar Box Cooker
    (International Research Publication House, 2019-02-02) Olumuyiwa A. Ogunwale; S.D. Adewumi; Adekunle Akanni Adeleke; T. Yahaya; John A.L. Ramonu
    This paper presents the exergy analysis of a typical multiple reflector solar box cooker. The fabricated cooker having multiple reflectors experimented in the summer day period at the premises of the University of Ilorin, Ilorin, Nigeria. Thermodynamics analysis was conducted to obtain performance evaluation of the cooker through applications of energy and exergy equations at ambient temperature. The results obtained show an increase in the exergy efficiency of the cookers concerning an increase in the number of reflectors used in construction.
