    Effect Of Temperature On Hyalomma (Hyalomma) Impeltatum Schulze And Schlottke (Ixodoidea: Ixodidae) حسب Khalil, Galila M. [جليلة مصطفى خليل]

    منشور في 1988
    "…Also, the percentage loss in weight by larvae before feeding and during molting and by nymphs and females before feeding was not affected by temperature but nymphal loss in weight during molting was greater at 34°C than at 21-29"C. Fifty percent of the egg masses were deposited within 7.9, 6.8, 4.6 and 4.2 days, and 90% within 20.0, 18.0, 11.6 and 9.3 days at the tested temperatures, respectively. …"

    Synthesis and electrochemical properties of nickel oxide/carbon nanofiber composites حسب Al-Enizi, Abdullah M.

    منشور في 2014
    "…These electrospun fibers were stabilized for 2 h at 200 °C and then carbonized at 800 °C for 5 h. Composites were prepared by depositing Ni(OH)2 on the carbon nanofibers (CNFs) and calcining them at different temperatures. …"

    Hydrogen Production via Ethanol Decomposition over Bimetallic Catalyst حسب Ashok, Anchu

    منشور في 2016
    "…Ethanol decomposition over bimetallic CuCo were conducted using in situ diffuse reflectance infrared fourier transform spectroscopy (DRIFT) study under N2 flow at different temperatures (50, 100, 200, 300, 400°C). Temperature-time profile of CuCo shows an increase in combustion temperature with increase in fuel ratio with maximum temperature at φ = 1 (stoichiometric ratio) and after that it decreases. …"
