    Comprehensive thermoeconomic, exergoeconomic, and optimization analyses of direct oxy-combustion supercritical CO2 intercooled and reheated cycles under design and off-design condi... حسب Al-Ammari, Wahib A.

    منشور في 2022
    "…At optimized conditions (Pc,o = 30 MPa, Pc,o = 8 MPa, TIT = 744°C, CIT = 30°C [wet-cooling]), the ICC shows superior energetic performance (52.08%) compared to 47.97% for DRC, 49.20% for PIC, and 48.62% for RHC. At off-design conditions with a power demand (PD) of 40% of the design load (50 MW), the thermal efficiency is decreased by 21.82% in DRC, 17.71% in ICC, 22.46% in PIC, and 13.60% in RHC. …"

    Preliminary Observations On The Relative Growth And Production Of Tilapia Species Cultured In Cages At Three Stocking Densities حسب Al Zahaby, A. S. [الاحمدي الذهبي]

    منشور في 1987
    "…Results indicated that the individual growth rate of both species decreased with increased stocking densities with a best aggregate stocking rate of 200 fish/m3 for both species.The maximum production rates of 32.0 and 17.4 kg/m^six months and final average size of 178.7 and 108.7 gm/fish were recorded for T.nilotica and T. galilaea respectively.The range of food conversion ratios for T. nilotica were between 2.83 and 3.57 while for T. galilaea were 3.88 and 5.20 with efficiency decreasing with increasing stocking density. …"

    High temperature thermal stability of innovative nanostructured thin coatings for advanced tooling حسب Cabibbo, Marcello

    منشور في 2014
    "…The main problem with steel, isthat itexhibits a relatively low hardness (below 10 GPa) which strongly decreases upon annealing above about 600 K.Thus, the majority of modern tools are nowadays coated with hard coatings that increase the hardness, decrease the coefficient of friction and protect the tools against oxidation. …"
