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

    Published 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. …”

    Dynamic stretching alone can impair slower velocity isokinetic performance of young male handball players for at least 24 hours by Haddad, Monoem

    Published 2019
    “…Two-way repeated measures ANOVAs revealed that 1) both the SS and control conditions exhibited knee extensor 60.s -1 (SS:-10.3%; p = 0.04, Control: -8.7%; p = 0.07) and 300.s -1 (SS: -12.9%; p = 0.005, Control: -16.3%; p = 0.02) isokinetic deficits at post-test, 2) DS impaired knee flexor 60.s -1 isokinetic work and power-related measures at post-test (Work: -10.1%; p = 0.0006; Power: -19.1%; p = 0.08) and at 24-hours' post-test (Work: 9.9%; p = 0.023; Power: -9.6%; p = 0.01), 3) DS (12.07% and 10.47%) and SS (13.7% and 14.6%) enhanced knee flexor 300.s -1 isokinetic force and power-related measures compared to control. …”

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

    Published 2021
    “…Due to the disadvantages of using pure biodiesel in engines, it was used as B50 (a blend of 50% diesel and 50% biodiesel). To enhance engine performance, n-pentane was used in different extents of 5, 10, and 15 ml per liter as an enhancer additive. …”
