in this paper, surface and piezoelectric effects on the vibration behavior of nanowires (nws) are investigated by using a timoshenko beam model. the electric field equations and the governing equations of motion for the piezoelectric nws are derived with the consideration of surface effects. by the exact solution of the governing equations, an expression for the natural frequencies of nws with ...
statins are most effective pharmacologically agents to decrease total plasma cholesterol level by competitive inhibition of hmg-co a reductase. apart from the well-known ldl and cholesterol lowering effect, statins have been postulated to exert other beneficial effects also called pleotropic or non-lipid effects. better understanding of various pleotropic effects of statins has prompted a new s...

Zusammenfassung Die Vernetzung kommunikationsfähiger Geräte schreitet aktuell schnell voran und verspricht durch eine Ende-zu-Ende-Digitalisierung von Prozessen Effizienzgewinne neue Anwendungsmöglichkeiten. Verifizierung Endgeräten ist insbesondere bei kritischen Infrastrukturen wie der Energieversorgung notwendige Bedingung. Unter anderem für die aktive Integration Kleinstanlagen Photovoltaik...
Manganese (Mn) has two roles in plant metabolic processes: an essential micronutrient and a toxic element when it is excess. Mn toxicity favored acidic nature soils. However, may possible that Mangan affects crop growth even though neutral states. This study aimed to determine the effect of manganese on seed germination both low pH pH. The was compiled using Randomized Complete Block Design wit...
the geopolitics of afghanistan after september 11, 2001, and its impact on iranian national security
abstract u.s. attack to afghanistan after 9/11 provided opportunities for us who tried to become the dominant power after collapse of ussr and bipolar world. thinkers like fukuyama believed american liberal democrats thought would be universally accepted without resistances. liberal democracy is the best and final model of governance; in this regard, united state has moral responsibilities for...
