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. …"

A cost effectiveness analysis of salt reduction policies to reduce coronary heart disease in four Eastern Mediterranean countries حسب Mason, Helen

"…The combination of all three policies (reducing salt consumption by 30%) resulted in estimated cost savings of $235,000,000 and 6455 LYG in Tunisia; $39,000,000 and 31674 LYG in Syria; $6,000,000 and 2682 LYG in Palestine and $1,3000,000,000 and 378439 LYG in Turkey. Conclusion: Decreasing dietary salt intake will reduce coronary heart disease deaths in the four countries. …"

Prevention of gallium arsenide photocorrosion by an epoxy adhesion layer حسب Alqaradawi, Siham Y.

"…The room temperature electrical conductivity of the epoxy films increased from 10−8 to 10−4Ω−1cm−1 due to gold impregnation. Enhancement of the photocurrent due to gold impregnation is attributed due to better conduction of the photogenerated holes into the electrolyte, also due to activating the adsorption of electrolyte ions.Several parameters are studied with the objective of determining the stability of epoxy films: these are continuous current–voltage (I–E) scans, prolonged illumination, weight changes and surface topography by scanning electron microscopy. …"

Microbial electrosynthesis feasibility evaluation at high bicarbonate concentrations with enriched homoacetogenic biocathode حسب Gunda, Mohanakrishna

"…The acetate production rate was found to increase with the increase in the bicarbonate concentration and evidenced a maximum production rate of 260 mg/L d−1 (15 g HCO3−/L). On the contrary, carbon conversion efficiency decreased with the increase in the bicarbonate concentration, which evidenced a maximum at 2.5 g HCO3−/L (90.16%). …"
