The investigation into the circumferential mechanical properties of tubular materials has been receiving increasing attention, since tube hydroforming process used in forming field, because have a significant effect on hydroformability materials. In present study, method for evaluation with flaring test was proposed. expressions yield stress, strain hardening coefficient and exponent values wer...

In order to understand organizational memory, it is important to understand how things become adopted as memory resources in organizations. In this paper, we describe the genesis and use of an artifact that became a memory resource for a wide range of activities. We discuss how the creation and use of the rush cheat sheet (RCS) and its associated representations at Dallas Ft. Worth TRACON broug...

Reading the medical literature requires some sophistication. This scoring sheet points out some important issues to consider when reading medical papers. Considerations raised herein are not to be taken as absolute, but instead as strong guidelines. Furthermore, this scoring sheet can be used in preparing manuscripts as it is a valuable “checksheet” to ensure all bases are covered. The more poi...

this information sheet contains the necessary information to educate mothers in the early weeks after delivery. so in a relaxed opportunity to read it. if you plan to feed your baby by breast feeding, it is necessary to read it prior to discharge from hospital. note that the duration of breast feeding in the first weeks after the labor is 20 minutes. the best way for breastfeeding is to give th...

Thin films of -MoGe show progressively reduced Tc’s as the thickness is decreased below 30 nm and the sheet resistance exceeds 100 / . We have performed far-infrared transmission and reflection measurements for a set of -MoGe films to characterize this weakened superconducting state. Our results show the presence of an energy gap with ratio 2 0 /kBTc=3.8 0.1 in all films studied, slightly highe...

Spreading resistance analysis on ultrashallow structures is complicated by the interaction of bevel rounding with geometric effects associated with lateral boundaries. When a spreading resistance probe is stepped from the original sample surface, across the rounded region at the bevel edge and onto the bevel, the resistance increases. Some of the increase is the result of approaching the latera...

Dual-pressure tube hydroforming (THF) is a tube-forming process that involves applying fluid pressure to tube’s inner and outer surfaces achieve deformation. This study investigates the effect of dual-pressure loading paths on material formability tribological conditions. Specifically, pear-shaped triangular cross-sectional parts were formed using modes where inside tubular blank was alternated...
