|1||Parametric Optimization of Gas metal arc welding process by using Taguchi method on stainless steel AISI 410 Abstract – Gas metal arc welding is a fusion welding process having wide applications in industries. Gas metal arc welding is one of the conventional and traditional methods to join materials. The present study is to investigate the influence of welding parameters on the penetration. The optimization for Gas metal arc welding process parameters (GMAW) of Martensitic Stainless steel work piece AISI 410 using Taguchi method is done. Sixteen experimental runs (L16) based on an orthogonal array Taguchi method were performed. This paper presents the effect of welding parameters like welding speed, welding current and wire diameter on penetration. The ANOVA and signal to noise ratio (S/N ratio) is applied to identify the most significant factor and predicted optimal parameter setting. Experiment with the optimized parameter setting, which have been obtained from the analysis, are giving valid the results. The confirmation test is conducted and found the results closer to the optimize results. These results showed the successful implementation of methodology.||Prof. S. D. Ambekar & Sunil R.Wadhokar|

Four different possibilities exist for the relative orientation of both rings, so four different isomeric families of compounds are defined: 1,2,4-triazolo[1,5-a]pyrimidine, 1,2,4-triazolo[1,5-c]pyrimidine, 1,2,4-triazolo[4,3-a]pyrimidine and 1,2,4-triazolo[4,3-c]pyrimidine. Among these isomeric families of compounds, 1,2,4-triazolo[1,5-a]pyrimidine derivatives are thermodynamically more stable and, thus, the most studied ones , a few of them being commercially available. Revisions surveying the synthesis, reactivity, spectroscopic characterization and crystallographic studies of 1,2,4-triazolo[1,5-c]pyrimidines , 1,2,4-triazolo[4,3-a]pyrimidines  and 1,2,4-triazolo[4,3-c]pyrimidines  have also been published. From the standpoint of biological activity, fused heteroaromatic systems are often of much greater interest than the constituent monocyclic compounds. Recently, 1,2,4-triazolo[1,5-a]pyrimidines have aroused increasing attention from the chemical and biological view points, due to their diverse pharmacological activities, such as antitumor potency [5, 6], inhibition of KDR kinase , antifungal effect  and macrophage activation . They have proved to be promising anticancer agents with dual mechanisms of tubulin polymerization promotion [5, 6] as well as cyclin dependent kinases 2 inhibition . Some examples of published derivatives of 1,2,4-triazolo[1,5-a]pyrimidine with their biological activities are as following.||Dipak C. Patel, Amish P. Khamar, Nirul V. Gothi|
