Present paper is devoted to stress and deformation analyses of heated variable thickness functionally graded (FG) circular plate with clamped supported, embedded on a gradient elastic foundation and subjected to non-uniform transverse load. The plate is coupled by an elastic medium which is simulated as a Winkler- Pasternak foundation with gradient coefficients in the radial and circumferential...

In this article, the bending and free vibration analysis of functionally graded (FG) nanocomposites Timoshenko beam model reinforced by single-walled boron nitride nanotube (SWBNNT) using micro-mechanical approach embedded in an elastic medium is studied. The modified coupled stress (MCST) and nonlocal elasticity theories are developed to take into account the size-dependent effect. The mechani...

THE development of resistance to 5-fluorouracil (FU) in Ehrlich ascites carcin-oma (EAC) cells has been accompanied by decreases in the activities of uridine kinase (Reichard et al., 1962) or of uridine phosphorylase and deoxyuridine phos-phorylase (Reichard, Skold and Klein, 1959). These enzymes of the " uracil pathway " of pyrimidine biosynthesis are involved in the conversion of FU to its ac...
