This study aimed to investigate the effect of electron beam welding parameters on the microstructural characteristics and mechanical properties of the dissimilar joint between 17-4PH precipitation hardening stainless steel and Ti6Al4V alloy. For this purpose, the welding of these two alloys was done without an interlayer and with an interlayer of copper with a thickness of 0.8 mm. Two different...
in order to examine the ecological conditions and characteristics of fraxinus excelsior l. in the northern forests of iran 6 main areas as well as some miscellaneous ones , have been selected in the region respectively in : lomir2, shafaroud , park - e-noor , ahlam , alandan and noor.
Partially liquefied vitreous humor is a common physical and biochemical degenerative change in vitreous body which the liquid component gets separated from collagen fiber network and leads to form a region of liquefaction. The main objective of this research is to investigate how the oscillatory motions influence flow dynamics of partial vitreous liquefaction (PVL). So far computational fluid d...
Recent research has shown a positive relationship between disgust sensitivity and blood–injection–injury (BII) fears. This line of research has also found that females report higher levels of BII fears and disgust sensitivity than males. The present study sought to determine if the sex difference in BII fears can be accounted for by the sex difference in disgust sensitivity in a sample of under...
The present study addresses three main questions: 1) Are schedule control and job autonomy associated differently with the work-home interface? 2) Do schedule control and job autonomy interact with different forms of work-home role blurring to influence levels of work-to-home conflict? 3) Do any of these observed patterns of association differ for women and men? We apply and refine a gender vie...
The objective of the present study was to examine race and gender differences in obesity and disease overtime. This topic is under studies in racial/ethnic minority populations. Yet, gender differences in health within ethnic groups provide a more nuanced approach to health disparities. The analyses for this study were based on two waves of data (Wave1, 1986 and Wave 2, 1989) of the Americans’ ...
The research progresses in static and dynamics tests, constitutive models, interface elements, model tests and field tests of pile soil interface are summarized, and the problems and deficiencies in the current research are analyzed. It is pointed out that research on the dynamic characteristics of pile soil interface widely seen in practical engineering are in lack. Especially, big size experi...
The effect of zinc phosphate (ZP) and zinc calcium phosphate (ZCP) coatings on the reinforcing mechanisms of smooth steel fiber in cementitious matrix have been studied. The results of pull out tests illustrated that by coating smooth steel fiber the pull-out load may be increased up to 100%. The effect of zinc phosphate coating on interface bonding was more than zinc-calcium phosphate coating....
resonances are intrinsic characteristics of an elastic object, which are completely independent of thesource of excitation. the appropriate utilization of the information contained within the resonancespectra and the identification of the resonance frequencies of the object can be used as a potent toolfor material characterization. in this paper, a new mathematical model for the wave diffractio...
