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

"…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. …"

Results from the first culturally tailored, multidisciplinary diabetes education in Lebanese adults with type 2 diabetes: effects on self-care and metabolic outcomes حسب Sukkarieh-Haraty, Ola

"…This pilot-study tested the effect of culturally-tailored education targeting diabetes selfcare on glycemia and cardiovascular risk factors of Lebanese with type 2 diabetes mellitus (T2DM) (n = 27; Age: 61 ± 10 yrs, 59% males, HbA1c: 8.98 ± 1.38%). Results: Diabetes self-care (Diet, Self-Monitoring Blood Glucose and foot care) improved after 6 months, which was reflected in a significant drop in glycemic levels (HbA1c:-0.5%; FPG: − 38 mg/dl), and cholesterol/HDL ratio (4.45 ± 1.39 vs. 4.06 ± 1.29). …"
