    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. …"

    EPIDEMIOLOGY OF CHLAMYDIA TRACHOMATIS IN LATIN AMERICA AND THE CARIBBEAN: SYSTEMATIC REVIEW, META-ANALYSES, AND META-REGRESSIONS حسب ABU-EL-RUZ, RASHA

    منشور في 2022
    "…We conducted random-effects meta-regressions to identify sources of heterogeneity and possible predictors of high prevalence. Results: The pooled-mean urogenital CT prevalence was 8.2% (95% CI: 7.5-9.1) for general populations, 14.0% (95%CI: 12.7-15.4) for female sex workers, 10.8% (95% CI: 8.4-13.4) for men who have sex with men, male sex workers, and transgenders, 16.1% (95% CI: 12.6-19.8) for symptomatic women, 25.4 (95% CI: 18.6-38.5) for symptomatic men, 9.7% (95%CI: 6.1-14) for HIV-positive individuals and individuals in HIV-discordant couples, and 11.9% (95 CI: 8.5-15.8) for STI clinic attendees. …"

    Development of pH-Controlled Aluminum-Based Polymeric Gel for Conformance Control in Sour Gas Reservoirs حسب Shamlooh M.

    منشور في 2020
    "…PAM/AlAc system has a gelation time of around 50 min at 75 °C making it suitable for near-wellbore treatments, while the gelation time increased to 80 min upon increasing the pH of the system from 4.1 to 4.6. Moreover, the system showed good stability in saline conditions with NaCl concentration of up to 50,000 ppm. …"

    Hydropriming with moringa leaf extract mitigates salt stress in wheat seedlings حسب Ahmed, Talaat

    منشور في 2021
    "…Therefore, the current study was conducted to evaluate the hydropriming of natural plant extract (moringa leaf extract) and water on wheat seeds and grown under different saline (0, 0.05, 0.1, 0.15, and 0.2 M NaCl) environments. The germination attributes (germination percentage, germination index, mean germination day, coefficient of variance, vigor index) and seedling growth (fresh weight, dry weight, root length, shoot length) were enhanced in the plants primed by moringa leaf extract. …"
