    Effect of reinforcement concentration on the properties of hot extruded Al-Al2O3 composites synthesized through microwave sintering process by Reddya, M. Penchal

    Published 2017
    “…Results showed that, as the content of hard ceramic particles increases, it improves overall mechanical properties including microhardness, 0.2% yield strength, ultimate compression/tensile strength, and Young's modulus while the ductility and co-efficient of thermal expansion decreases. XRD patterns and SEM/EDS mapping images show a uniform distribution of Al2O3 particles in the Al matrix. …”

    Experimental study of exhaust emissions and performance of a dual fuel IDI diesel engine by Badr, O.

    Published 1999
    “…Methane and, sometime, propane were used as the gaseous fuel while regular diesel fuel was used as the pilot one. The admission of more gaseous fuel with the intake air increased the engine power, thermal efficiency, and NOx emissions while CO and UHC emissions increased up to the flame initiation limit beyond which they decreased sharply. …”

    A Review of Pharmacogenetics of Antimalarials and Associated Clinical Implications by Elewa, Hazem

    Published 2017
    “…Lumefantrine concentrations were also influenced by ABCB1 variants in the presence of nevirapine. The most critical pharmacogenetic consideration identified was the association of glucose-6-phosphate dehydrogenase deficiency with development of hemolytic anemia and decreased hemoglobin levels in patients treated with primaquine or a combination of chlorproguanil-dapsone-artesunate. …”
