    Potential of nightsky nocturnal radiative cooling as a fresh produce preservation method 

    Gikuru, Mwithiga; Kirui, Anthony C. (2007-07-30)
    Abstract: The change in water temperature in horizontally placed pans exposed to the night-sky radiation was monitored at night between the hours of 8:00pm and 6:00am. The effect of varying the quantity of water in the pan ...

    Effect of moisture content on the physical properties of three varieties of sorghum seeds 

    Gikuru, Mwithiga; Sifuna, Mark Masika (Elsevier, 2006-08-31)
    Three sorghum varieties (Kari-mtama, Serena and Seredo) were obtained from the Kenya Agricultural Research Institute and reconditioned to moisture contents ranging from 13.64% to 21.95% db. The reconditioned grain kernels ...

    Comparison of a gas fired hot-air dryer with an electrically heated hot-air dryer in terms of drying process, energy consumption and quality of dried onion slices 

    Gikuru, Mwithiga; EL-Mesery, Hany S. (Academic Journals, 2012-08-14)
    Onion slices were dried in either a gas-fired hot air dryer or an electrically heated hot air dryer at air temperatures of 50, 60 or 70°C, and at air flow velocities of 0.5, 1.0 or 2.0 m/s. Records of the drying rates and ...
