    Screening of Qatari Microalgae and Cyanobacteria for Application in CO2 Utilization by Schipper, Kira

    Published 2018
    “…Picochlorum maculatum was found to have the highest lipid and protein content, with 24.0 ± 1.3, 28.0 ± 1.4 and 27.0 ± 1.4 % (w/w) lipids and 21.2 ± 0.2, 23 ± 0.1, and 20 ± 0.9 % (w/w) proteins for cultivation at 30, 35 and 40˚C respectively. This strain also had the highest nitrogen content (12.2 ± 0.05 % at 40˚C) and carbon content (51.2 ± 0.25 % at 45˚C). …”

    Effect of plastic deformation on Corrosion of cadmium in 0.1 m sodium Sulphate solution by Kandeil, A. Y. [عبد الرزاق يوسف قنديل]

    Published 1993
    “…The present investigation was carried out to study the influence of prior plastic deformation and surface finish on the corrosion behaviour of pure cadmium in 0.1 M Na2SC>4 solution at 25° C. Cylindrical specimens were deformed by compression to different levels of deformation up to 90% reduction in height (RH). …”

    Polarization Resistance Study on Copper Corrosion in Aqueous Potassium Hydrogen Phthalate Solution by Mouhad, M. Y.

    Published 1987
    “…The effect of temperature on corrosion of copper in 0.1 M aqueous solution of potassium hydrogen phthalate (KHPh) has been investigated using polarization resistance technique. it was found that that the corrosion rate in the range 25�65�C obyes Vant Hoff's and Arrhenius Laws. The results indicate that corrosion of copper in KHPh is mainly cathodically controlled process. …”

    Synergistic effects and optimization of nitrogen and phosphorus concentrations on the growth and nutrient uptake of a freshwater Chlorella vulgaris by Alketife, Ahmed M.

    Published 2017
    “…1 and the maximum biomass produced was decreased more than three-fold to 0.5 g/L. The Box Behnken experimental design and response surface method were used to study the effects of the initial concentrations (P, N and C) on P and N removal efficiencies. …”
