Laws of programming are important not only to define the axiomatic semantics of programming languages but also to assist in the software development process. In fact, these laws can be used as the foundation for informal development practices, such as refactorings, widely adopted due to modern methodologies, in special Extreme Programming. Although they have not been sufficiently studied yet, m...
Development of electronic industries, compression of electronic equipment, and removing lead from electronic circuits for environmental issues, resulted in a significant challenge in design and development of tin-based lead-free solders with physical and mechanical properties similar to old tin-lead alloys. In this regard, the set of Sn-Ag-Cu alloys with eutectic and near eutectic compositions ...

In this paper redox reaction processes and phase, formation on ternary Pb-2Sn-0.08Ca alloy utilized as insoluble lead anodes in copper electro winning cells, were investigated in 2M H__2SO__4 electrolytes, using cyclic voltammetry technique (CVA). A potential range between - 1.3V to 2.6V was chosen at various scan rates in order to study the anodic behavior and phase composition of the oxide la...
The helium production rates in liquid metals (Pb-Li eutectic alloy, LLE and others) Blanket Breeders (BB) are nearly mol-to-mol linked to tritium intimately associated with the compulsory requirement of high self-sufficiency next fusion reactors. When is oversaturated solubility limit exceeded, atoms can nucleate form bubbles. presence bubbles within channels could have severe impact on diverse...
