L'Inde occupe le deuxième rang mondial pour la production de légumes. Cependant, le chou est l'un des légumes-feuilles les plus importants. Le chou pourrait provenir d'Europe de l'Est et s'être répandu dans le monde entier grâce aux voyages et au commerce. En Inde, il est cultivé sur les collines toute l'année et comme culture d'hiver dans les plaines. En tant que culture de courte durée, supérieure sur le plan nutritionnel et capable de produire une grande quantité de nourriture par unité de surface et de temps, le chou a un grand potentiel dans l'agriculture moderne. Il fournit...

The main objective of this project work was to asses grinding wear behavior of austempered ductile iron balls. In this project, ductile iron balls were austenitised at 900 c and subjected to two step austempering heat treatment process. In the two step austempering process, the first step temperatures were 300 C for 60 minutes and then up quenched to higher temperature of 400 C for 60 min. Wear studies were carried out in dry and wet grinding conditions, in varying PH values from 7 to 10 and compared these results with En-31 forged steel balls. Same balls were used to grind the iron ore and...

Arsenic (As) contamination of rice is a major problem for South-East Asia. Effect of selenium (Se) on rice plants exposed to As. Presence of Se decreased As accumulation by 3-fold in roots and 2-fold in shoots as compared to single As exposed plants. Arsenic induced oxidative stress in roots and shoots was significantly ameliorated by Se supplementation. Positive response was found associated with the increased activities of antioxidant enzymes, induced thiolic ligands and phytochelatins in As+Se exposed plants as compared to single As treatment. Selenium supplementation modulated the thiol...
