    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. …"

    Spatial, temporal, and demographic patterns in prevalence of chewing tobacco use in 204 countries and territories, 1990-2019: A systematic analysis from the Global Burden of Diseas... حسب Kendrick, Parkes J

    منشور في 2021
    "…Prevalence among young people aged 15–19 years was over 10% in seven locations in 2019. Although global age-standardised prevalence of smoking tobacco use decreased significantly between 1990 and 2019 (annualised rate of change: –1·21% [–1·26 to –1·16]), similar progress was not observed for chewing tobacco (0·46% [0·13 to 0·79]). …"

    Compressive And Tensile Strength Of Concrete Loaded And Soaked In Crude Oil حسب Abdul Ahad, Ramzi B.

    منشور في 2000
    "…Results show that the rate of crude oil absorption is high at early stages of soaking, but this rate decreases with time. There is a reduction in the absorption by 30 to 40 percent of ultimate strength in specimens exposed to instantaneous loading as compared with unloaded specimens. …"
