    The effects of attendance and high school GPA on student performance in first-year undergraduate courses by Al Hazaa, Khalifa

    Published 2021
    “…The study uses census data and records of 969 undergraduate students at Qatar University to investigate the impact of HSGPA, attendance, and socio-demographic factors on academic performance in higher education in DFW courses (grades D, F, or withdrawal). Findings indicate that increased attendance decreases the likelihood of getting DFW, and there was a strong negative relationship between high-school performance and the probability of getting DFW. …”

    Effect Of Sand Blasting On Soda Lime Glass Properties by Bousbaa, C.

    Published 2003
    “…The average strength remains almost constant while the dispersion becomes much reduced for the glass sand blasted during 60 minutes (m = 10.4 and smoy = 64 MPa). The variation of the relative efficiency of glass protected solar panels versus sand blasting duration (seen up to 300 min) shows a slow regular decrease until 0.91 for a 90° impact angle and until 0.95 for 30°. …”

    High temperature thermal stability of innovative nanostructured thin coatings for advanced tooling by Cabibbo, Marcello

    Published 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. …”
