    The Impact of Acute and Chronic Exercise on Immunoglobulins and Cytokines in Elderly: Insights From a Critical Review of the Literature. by Sellami, Maha

    Published 2021
    “…Chronic exercise in the form of short-term endurance training (i.e., 12-16 weeks) and long-term combined endurance and resistance training (i.e., 6-12 months) induced increases in salivary SIgA concentration. We additionally identified that short-term endurance training at moderate intensities and the combination of endurance, strength, balance, and flexibility training increase plasma IL-10 and reduce plasma IL-6 and TNF-α in healthy elderly adults and male patients with chronic heart failure. …”

    Morphology, nucleation, and isothermal crystallization kinetics of poly(butylene succinate) mixed with a polycarbonate/MWCNTs masterbatch by Gumede, Thandi P.

    Published 2018
    “…Standard DSC scans showed that the MWCNTs nucleation effects saturated at 0.5 wt% MWCNT content on the PBS-rich phase, above this content a negative nucleation effect was observed. Isothermal crystallization results indicated that with 0.5 wt% MWCNTs the crystallization rate was accelerated, but further increases in MWCNTs loading (and also in PC content) resulted in progressive decreases in crystallization rate. …”

    Combustion and emissions of a gas-to-liquid diesel engine utilizing optimized spiral-helical intake manifold designs by Abdellatif, Yasser M.

    Published 2021
    “…For the emissions, the maximum reduction in CO emissions was achieved by using m(2.6,30,3t) and GTL with about 34%. In addition, the maximum hydrocarbon (HC) reduction was achieved by m(2.1,30,3t) and GTL, which is about 99% lower than that of the normal manifold. …”

    Morphology, Nucleation, and Isothermal Crystallization Kinetics of Poly(ε-caprolactone) Mixed with a Polycarbonate/MWCNTs Masterbatch by Gumede, Thandi P.

    Published 2017
    “…Isothermal crystallization experiments performed by DSC showed an increase in the overall crystallization kinetics of PCL with increases in MWCNTs as a result of their nucleating effect. Nevertheless, the crystallinity degree of the nanocomposite containing 4 wt % MWCNTs decreased by about 15% in comparison to neat PCL. …”

    Effects of covid-19 lockdown on physical activity, sedentary behavior, and satisfaction with life in Qatar: A preliminary study by Hermassi, Souhail

    Published 2021
    “…The largest reduction was detected for the sum parameter all physical activity (minutes per week, ηp2 = 0.67, p < 0.001; MET (metabolic equivalent of task)-minutes/week, ηp2 = 0.69, p < 0.001). Life satisfaction decreased, with the score for “I am satisfied with my life” (ηp2 = 0.76, p < 0.001) decreasing from 28.1 ± 4.81 to 14.2 ± 6.41 arbitrary units (AU). …”
