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 …

Labeling transparency and heavy metal contamination in commercial protein powders: A case study
Abstract: With the recent surge in market demand, health supplements particularly protein powders, have become increasingly vulnerable to quality deterioration, adulteration, and unethical marketing practices. Non-compliance with labeling regulations is on a rise. Moreover, research indicates that heavy metals absorbed from contaminated soil often accumulate in the protein fractions of crops, thereby elevating the risk of heavy metal contamination in protein powders. These issues highlight the urgent need to systematically assess …

Exploring the Synergistic Effects of Heavy Metal contaminants on Aquatic Organisms
Abstract: Human activities have a profound effect on aquatic habitats by altering water and sediment quality, which in turn impacts resident organisms. These changes are primarily caused by pollutants from agricultural, industrial, and health-related sources. Industrial effluents, often containing hazardous heavy metals such as chromium, manganese, and lead, are a major source of environmental toxicity. The discharge of these pollutants makes water unsafe for drinking, irrigation, and industrial uses, necessitating effective …

Feasibility Study of using Electric Down-hole Heating to Improve the Productivity for a Heavy Oil Field
Abstract: The largest hydrocarbon reserves around the world are mostly heavy oils. Electrical Down-hole Heating (EDH) is a widely used technique for heavy oil production; when it is combined with Enhanced Oil Recovery (EOR) methods, it can overcome its limitations. Considering limited previous studies for the designing of EDH for Sudanese fields, this paper presented the feasibility of using this system by simulating the actual well situation and provided several scenarios …
