Research ArticleOpen accessEvery word in the titleSecretary IgA Concentrations and plasma Cell Count Changes Associated with the Estrous Cycle in EwesMorteta H. AL-Medhtiy, A. B.Z. Zuki, M. M. Noordin, S. AgungpriyonoProblems statement: The level of uterine Secretory-IgA (S-IgA) and numbers of plasma cells was measured to observe the differences between two stages of estrous cycle (follicular and luteal phase) in the healthy cycling non pregnant ewes. Approach: Twelve ewes were used in this study and they were divided into two groups of 6 animals each according to the stages of … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,194 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEstimation of C*-Integral in Thin T-Sections Subjected to Projection and Remote Loading Base on Elastic Stress Concentration FactorA.R. Gowhari-Anaraki, F. Djavanroodi, S. ShadlouThe finite element method has been used to predict the creep rupture parameter, C*-Integral of flat T-section bar subjected to loaded projection and remote loading with a crack or crack-like flaw introduced in the fillet (i.e., high stress) region of the component. In this study, a new dimensionless creeping crack configuration factor, Q* has been introduced. Power low creeping finite … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,471 accessesView PDFCite
