    Effect Of Sand Blasting On Soda Lime Glass Properties حسب Bousbaa, C.

    منشور في 2003
    "…The variation of the relative efficiency of glass protected solar panels versus sand blasting duration (seen up to 300 min) shows a slow regular decrease until 0.91 for a 90° impact angle and until 0.95 for 30°. …"

    Prediction of biogas production from chemically treated co-digested agricultural waste using artificial neural network حسب Almomani F.

    منشور في 2020
    "…The results demonstrated that co-digestion of ASWs with CM with a ratio of 70% to 30% produced the highest CMP of 334 ± 4 NL/kgVS in comparison with 230 ± 10 NL/kgVS for mono-digested substrate. …"

    Numerical simulation of stall development into surge and stall control using air injection in centrifugal compressors حسب Halawa, Taher

    منشور في 2014
    "…Results also showed that during surge, forces on the impeller blades increase to nearly double of its initial value and then decrease again. By using air injection at the vaneless region with different injection angles, it was found that injection with angle of 30° has a good effect on preventing surge and minimizing the pressure fluctuations comparing to other injection angles results. …"
