a new method for increasing ldr in deep drawing is application of anti-lock braking system (abs) on blank holder. in this method, instead of applying a constant force on blank and control the metal flow, the abs system holds and releases the blank several times (20 to 50 times) which results increasing ldr. this study investigates the effect of different parameters of abs on improving the condi...

An asymptotic formula has been obtained for the axial tension in nonlinear viscoelastic fibers undergoing inhomogeneous stretch. The formula, which is valid to within an error of the fourth order in diameter, expresses the tension per unit cross-sectional area in terms of the history of the local axial stretch and its first two derivatives with respect to distance along the fiber axis. The theo...

Cold drawing is a commonly used metal forming technique carried out by pulling billet through die cavity to obtain desired dimensions. Ideally, the cross-sectional area of drawn product should be equal that at its exit; however, former one always larger after drawing, in practice. In this study, cold an AISI-316 stainless steel rod investigated finite element analysis. The difference between ra...

In 1971, Linus Pauling carried out a meta-analysis of four placebo-controlled trials and concluded that it was highly unlikely that the decrease in the "integrated morbidity of the common cold" in vitamin C groups was caused by chance alone (P < 0.00003). Studies carried out since then have consistently found that vitamin C (≥1 g/d) alleviates common cold symptoms, indicating that the vitamin d...

This paper draws on the thought of historian science, Georges Canguilhem, to explore how practice making medical knowledge brings into question accepted understandings (ill)health and contagious disease.
