Recent studies indicate the chemopreventive role of resveratrol in many animal models like ischemia, rheumatoid arthritis, human cancer, and diabetes. The present study was designed to investigate the chemopreventive potential of resveratrol in rat hepatic injury model by carbon tetrachloride. Male Wistar rats were treated with carbon tetrachloride (0.4(More)
A numerical study to investigate the steady laminar natural convection flow in a square cavity with uniformly and non-uniformly heated bottom wall, and adiabatic top wall maintaining constant temperature of cold vertical walls has been performed. A penalty finite element method with bi-quadratic rectangular elements has been used to solve the governing(More)
A new trend was developed for the formation of a complex between vanadium and flavonoid derivatives in order to increase the intestinal absorption and to reduce the toxicity of vanadium compounds. The vanadium–rutin complex was characterized by several spectroscopic techniques like ultraviolet (UV)–visible, Fourier transform infrared (FTIR), NMR, mass(More)
A block graph is a graph in which every block is a complete graph. Let G be a block graph and let A be the adjacency matrix of G. We first obtain a formula for the determinant of A over reals. It is shown that A is nonsingular over IF2 if and only if the removal of any vertex from G produces a graph with exactly one odd component. A formula for the inverse(More)
A penalty finite element analysis with bi-quadratic elements is carried out to investigate the effects of uniform and non-uniform heating of inclined walls on natural convection flows within a isosceles triangular enclosure. Two cases of thermal boundary conditions are considered; case I: two inclined walls are uniformly heated while the bottom wall is cold(More)
Cellular automata (CAs) are dynamic frameworks which exhibit complex global behavior from simple local interaction and computation. Since the inception of CA by von Neumann in 1950s, it has attracted the attention of several researchers over various backgrounds and fields for modeling different physical, natural as well as real-life phenomena. Classically,(More)
