15. Equivalence of lower bounds on the number of perfect pairs

Abstract

Let c(F) be the number of perfect pairs of F and c(G) be the maximum of c(F) over all (near-) one-factorizations F of G. Wagner showed that for odd n, c(K_{n}) \geq n*phi(n)/2 and for m and n which are odd and co-prime to each other, c(K_{mn}) \geq 2*c(K_{m})*c(K_{n}). In this note, we establish that both these results are equivalent in the sense that they both give rise to the same lower bound., Comment: 8 pages

Abstract

The aim of this article is to evaluate antioxidant activity of leaf extract of Magnolia champaca by using in vitro assay. Extraction was carried out with ethanol by using Soxhlet apparatus. The invitro antioxidant activity of ethanol extract has been investigated by 1, 1-diphenyl, 2-picryl–hydrazyl free radical (DPPH) method. The ethanol extract exhibited maximum antioxidant activity. The results have been compared with the standard ascorbic acid.

34. EFFECT OF FORGE FORCE ON MECHANICAL PROPERTIES OF DISSIMILAR METAL FRICTION WELDS OF STAINLESS STEEL AND LOW CARBON STEEL

Author

Ramana, P., Pratyusha, M., Ramanjaneyulu, K., and Narsimha, P.

Abstract

Several structural applications demand use of steels like low carbon steels and stainless steels because their sound weldability and ductility. Fusion welding of these steels especially in dissimilar metal combination attracts many problems such as cracking, porosity, low ductility etc. To overcome these problems, solid-state welding processes such as friction welding has to be employed as it can provide a solution to the recurrent problems arising in fusion welding. An attempt is made in this work to study the effect of forge force on mechanical properties such as tensile strength and impact toughness of the similar and dissimilar metal friction welds of stainless steel and low carbon steel. It is observed that tensile strength of dissimilar metal welds increased with increase in the forge force while the impact toughness decreased with increase in the forge force.
