    Biocorrosion behavior of biodegradable nanocomposite fibers coated layer-by-layer on AM50 magnesium implant حسب Abdal-hay, Abdalla

    منشور في 2016
    "…The results showed that the AJS 3D membrane fiber layers, particularly the hybrid membrane layers containing a small amount of nHA (3wt.%), induce a higher biocorrosion resistance and effectively decrease the initial degradation rate compared with the neat AM50 coupon samples. …"

    Study of performance, combustion, and emissions parameters of DI-diesel engine fueled with algae biodiesel/diesel/n-pentane blends حسب Elkelawy, Medhat

    منشور في 2021
    "…Through performance tests, it was found that 15 ml of n-pentane per liter was the best addition as it caused an increase in the brake thermal efficiency of 7.1% and a decrease in brake specific fuel consumption of 6.4% compared to the elegant B50. …"

    Optimization of performance and emission characteristics of CI engine fueled with Jatropha biodiesel produced using a heterogeneous catalyst (CaO) حسب Singh, A.

    منشور في 2020
    "…The optimum performance and emission characteristics (BP, BTHE, HC and NOx) are found to be 2.258 KW, 29.05%, 6.31 ppm, and 159.5 ppm respectively. The performance of B20 fueled engine was almost comparable to that of diesel fuel. …"

    Enhancing the production of biogas through anaerobic co-digestion of agricultural waste and chemical pre-treatments حسب Almomani F.

    منشور في 2020
    "…The results revealed that the highest cumulative methane production (CMP) of 297.99 NL/kgVS can be generated by co-digestion of ASWs and CD at a ratio of 60:40. Further improvement was achieved via alkalinity treatment with 1.0 g of NaHCO3/gVS leading to decrease in lignin, cellulose, and hemicellulose contents of feedstock by 3.5%, 10.5% and 15.9%, respectively, converting them to soluble fractions and improving the CMP by 11.2–29.7% based on substrate quality. …"

    The Separation of Emulsified Water/Oil Mixtures through Adsorption on Plasma-Treated Polyethylene Powder حسب Abdulkareem, Asma

    منشور في 2021
    "…The efficiency of the plasma-treated LDPE powder in oil removal was found to be dependent on the initial oil concentration. It decreased from 96.7% to 79.5% as the initial oil concentration increased from 75 ppm to 200 ppm. …"

    Tests of a diamond field-assisted positron moderator حسب Al-Qaradawi, I. Y.

    منشور في 2002
    "…A potential difference of up to 300 V could be held across the film with a leakage current of ∼ 10 nA. Although positron re-emission was observed from the diamond surface, the re-emitted fraction was observed to decrease when a bias of 300 V was applied across the film. …"
