Impact of Storage Methods and Duration on Sugar and Starch Content and Ethanol Yield of Sweet Potatoes [Ipomoea batatas (L.) Lam]
Abstract: Previous studies have shown that ‘industrial’ sweet potatoes can be an excellent feedstock for ethanol production as compared to corn, sorghum and other potential feedstocks. However, starch content can be affected by cultivars as well as storage conditions. Ideally, it is practical that sweet potato storage roots be processed for ethanol production as close to harvest as possible, but this may not always be the case and some amount of …

Application of flux cored arc welding (fcaw) without pre-heating for heavy structures in ship building fabrication & construction of heavy offshore structural steels
Abstract: In fusion welding processes, the reason often given to explain the need for preheating, controlling the inter pass temperature (in multi-pass welds), and post-weld heat treatment (PWHT) is to reduce the risk of residual stresses and it can be removed by heating weldment in the heat affected zone (HAZ). Cold cracking is a hydrogen embrittlement phenomenon, often referred to as hydrogen induced cracking or HAZ cracking. During the construction and …
