Metal forming processes, compared with machining ones, reduce production steps and increase manufacturing speed in addition to saving raw material. In this paper, forming process of column of a steering mechanism is investigated by finite element analyses and experimental tests; and optimum die design parameters are found. Forming process parameters including die opening angle, bearing length, ...

OBJECTIVE To assess the predictive value of quantitative fetal fibronectin (fFN) concentration in cervicovaginal fluid for spontaneous preterm birth in women with bulging fetal membranes. STUDY DESIGN This was a prospective observational study from five UK tertiary centres of a cohort of women with singleton pregnancy and bulging fetal membranes presenting between 18 and 32 weeks of gestation...

WE HEREIN REPORT A PATIENT WITH ACUTE APPENDICITIS WHO WAS DIAGNOSED BY COLONOSCOPY: a 54-year-old woman with normal physical examination and laboratory results within normal limits. The case had shown an erythematous and edematous bulging polypoid lesion with purulent discharging from appendiceal orifice into the cecum. At colonoscopy, appendix appeared as an erythematous and edematous bulging...

Although computed tomographic (CT) myelography and magnetic resonance imaging (MRI) are used for assessing lumbar disc herniations (LDH), they cannot provide images when patients are standing or walking, whose CT myelograms and MRI images show only slight disc bulging. The purpose of this study was to evaluate the usefulness of upright myelography. We examined by myelography in both an upright ...

In this study, the rheological characteristics of a titanium alloy have been obtained by multi-dome bulging test. Free bulging process is an experimental technique that can be used to characterize material in conditions of biaxial tension during superplastic, as well as conventional, hot forming. The constitutive constants are calculated on a base of the information about the bulge geometry, ap...

In this study, we investigated geometrical characteristics of the inkjet-printed lines with non-zero receding contact angle (CA) on plasma-treated substrates in terms of various printing variables and analyzed the fluidic behavior and hydrodynamic instability involved in the line formation process. The printing variables included surface energy, droplet overlap ratio, printing frequency, a numb...
