In hot dip galvanizing, several parameters such as chemical composition of coating bath, immersion time and surface roughness of specimens could affect microstructure and properties of coating. In this article, the effect of aluminum content, immersion time and surface roughness on structure and properties of alloy layers have been investigated. Specimens of low carbon silicon-free steel with d...

The stability behavior of low immersion helical end milling processes is investigated in this paper. Low radial immersion milling operations involve interrupted cutting which induces chatter vibration under certain cutting conditions. Time Finite Element Analysis (TFEA) is suggested for an approximate solution for delayed differential equations encountered during interrupted milling. An improve...

ore than thirty years of language immersion instruction in Canada and the United States have produced an impressive body of research demonstrating its benefits to students. This research indicates that students gain proficiency in a second language, develop cultural awareness, and perform as well as or better than their non-immersion peers on English proficiency tests (Rubio, 1998). As a result...

For the next-generation immersion lithography technology, there is a growing interest in the immersion fluids having a refractive index larger than 1.5 and low absorbance at 193nm wavelength. In this paper, we report our effort in identifying new immersion fluid candidates. The absolute refractive index values and thermo-optic coefficients, dn/dT, were measured with 1x10 and 1x10 accuracy respe...

Adult human brains retain the capacity to undergo tissue reorganization during second-language learning. Brain-imaging studies show a relationship between neuroanatomical properties and learning for adults exposed to a second language. However, the role of genetic factors in this relationship has not been investigated. The goal of the current study was twofold: (i) to characterize the relations...

BACKGROUND A cold provocation test is used to assess the presence and extent of the peripheral vascular disorders in the upper extremities of workers exposed to hand-arm vibration. A quantitative evaluation of vascular response to cold provocation is determined by measuring the finger skin temperature. In the study two methods of cold exposure were used to assess the effect of water temperature...

BACKGROUND Cold water immersion (CWI) is a technique commonly used in post-exercise recovery. However, the procedures involved in the technique may vary, particularly in terms of water temperature and immersion time, and the most effective approach remains unclear. OBJECTIVES The objective of this systematic review was to determine the efficacy of CWI in muscle soreness management compared wi...
