  • Let K be a nonempty subset of a normed linear space X and let x $\in$ X. An element k$_0$ in K satisfying $\$\mid$$x - k$_0$$\$\mid$$ = d(x, K) := (equation omitted) $\$\mid$$x - k$\$\mid$$ is called a best approximation to x from K. For any x $\in$ X, the set of all best approximations to x from K is denoted by P$_K$(x) = {k $\in$ K : $\$\mid$$ x - k $\$\mid$$ = d(x, K)}. (omitted)

  • Galvannealed Sheet Steel, which is being widely used in the automotive industry, is made by reheat after dip zinc galvanizing process. By this, A Fe-Zn alloy is created which enhance anticorrosive property and weldability. This paper describes basic design for 2000kW induction heating inverter system for galvannealling process and test result of 250kW inverter module which is used in parallel to form 2000kW inverter system.

  • We have developed polymer LED displays using ink jet printing without visible swathe marks which can be observed during display operation. In addition, we have also developed a single-pass printing technology for hole-conduction layer deposition to significantly reduce the complexity of interlacing printing across the panel which is known as an alternative to remove the swathe mark.

  • The protective effect of Bifidobacterium breve K-110, K-111 and B. infantis K-525 on carbon tetrachloride induced hepatotoxicity in rats was investigated. Among them, B. infantis K-525 had the most potent hepatoprotective activity. It reduced serum aspartate aminotransferase and alanine aminotransferase levels to 51% and 80% of the $CCl_{4}-treated$ groups, respectively. In rat liver homogenate intoxificated with $CCl_{4}$, B. infantis K-525 inhibited in vitro as well as in vivo lipid peroxidation more than the other Bifidobacteria.
