A theorem of this paper proves that if the size distribution of random spheres is generalized gamma, its Wicksell transform and other related distributions belong to the domain of attraction of the Gumbel distribution. The theorem also shows the attraction coefficients of the distributions. The fatigue strength of high-strength steel is closely related to the maximum size of nonmetallic inclusi...

This paper analyzes from the perspective of Service-Dominant Logic how value is generated through supply chain integration. The inclusion together with Transaction Costs Economy and Resource Based View allows exploring ways explaining generation that have been seldom studied. In particular, role specific resources, governance form, information sharing are analyzed in Spanish mining manufacture ...

Tinplate is widely used in food packaging and chemical packaging. Industrial production continues to reduce the thickness of tinplate steel, which puts higher requirements on control inclusions. In this study, compared with traditional detection methods, Ultrasonic Detection method can analyze distribution nonmetallic inclusions larger size samples, closer actual process. The numerical simulati...

In some applications, deep desulfurization and deoxidation of steels without the use aluminum are required, using Si as a deoxidant instead, with double-saturated slags in CaO-SiO2-CaF2-MgO system. This work studied nonmetallic inclusion evolution for system an induction furnace compared results FactSage kinetic simulations. Steel samples were taken from steel melt analyzed ICP-MS combustion an...

From the use of renewable resources and environmental protection viewpoints, recycling of waste printed circuit boards (PCBs) receives wide concerns as the amounts of scrap PCBs increases dramatically In recent years there has been increasing concern about the growing volume of end of life electronics and the fact that much of it is consigned to landfill w ithout any attempt being made to recyc...

STUDY DESIGN A variety of interbody implants were imaged by computed tomography and plain radiography within cadaveric spines to evaluate their basic imaging characteristics. OBJECTIVES Sources of interpretation error by both computed tomography and plain radiography of interbody implants were investigated. SUMMARY OF BACKGROUND DATA Lucencies have been reported around bone dowel implants i...

In this study, the effects of Ce (270 ppm) and La (120 ppm) mischmetal additions on the transient oxidation of an Fe-22Cr alloy were investigated. The oxidation process was imaged in situ using a confocal scanning laser microscope. The oxidation microstructures were studied by scanning electron microscopy, energy dispersive X-ray analysis, and transmission electron microscopy with the help of f...
