    Design, Fabrication and Performance Evaluation of Awning/Canopy for Thermal Comfortability
    (Journal of Engineering and Technology, 2017) Ajao, K.R.; Yahaya, T.; Kolawole, M.Y.; Aweda, J.O.
    This paper presents the design, fabrication and performance evaluation of retractable awning/canopy system for thermal comfortability. It consists of frame (mild steel bars), linear actuator, fabric (acrylic), adapter, roller pathways and photo sensor (for easiness of control). After fabrication and coupling of the whole components of the retractable awning and connecting to the adapter and power source for performance test evaluation, it was observed that, the actuator arm which was coupled to the fabric began projecting outward and once the photo sensor was shaded from sunlight using a dark material, the fabric retracted into the roller. Also it was noted that, shading the window provided a reduced solar heat gain factor of 28.16W as compared to the solar gain factor of 498.54 W before shading the window with a cooling load of 415.37 W achieved. This can be incorporated into a building plans especially those at the sun heating direction and temperature region to reduce inner temperature aid air-conditioner loading for longer life and efficient operation.

    Evaluation of noise pollution and effects on workers during wheat processing.
    (Journal of Applied Science and Environmental Management (JASEM), Published by University of Port Harcourt, Nigeria., 2014) Ibrahim, I.B.; Aremu, A.S.; Ajao, K.R.; Ojelabi, A.T.
    ABSTRACT: This study assessed the intensity and likely effects of noise on workers during wheat processing. Noise measurements were taken using HD600 sound level meter. Subjective assessment of the effects of noise was undertaken using semi structured questionnaire. Also audiometric test was conducted on workers using AD229e diagnostic audiometer. The results of the study show that during wheat processing operations, the noise level in the factory ranges between 56.0 dB(A) and100.9 dB(A). Also, only 25.6 % of all the readings was below the specified limit of 85 dB(A). Workers are also observed to have certain forms of physiological and psychological disorders related to noise. The audiometric test results revealed that 33 % of the examined workers have defect in their left or right ear. Based on these results, WHO Class-5 hearing protector is recommended to be worn by workers in the processing sections while room acoustics should be upgraded to absorb some sounds transmitted to offices.
