آلیاژ al-1050 یک آلیاژ عملیات حرارتی ناپذیر آلومینیوم از سری xxx1 می¬باشد. به طور کلی آلیاژهای آلومینیوم به دلیل وزن کم و استحکام مناسبی که دارند در صنعت بسیار مورد استفاده قرار می¬گیرند. از این رو بهبود خواص این مواد بسیار اهمیت پیدا کرده است. روش fsp در سال 1991 در انگلستان به عنوان یک روش کارآمد برای بهبود خواص آلومینیوم به جهان معرفی شد. در این روش از یک ابزار سخت استفاده می¬شود که با چرخش ...

The deep drawing is a process for shaping flat sheets into cup-shaped articles without failure or excessive localized thinning. The design and control of a deep drawing process depends not only on the material, but also on the condition of the tool material interface, the mechanics of plastic deformation, the equipment used, and the control of metal flow. The equipment and tooling parameters th...

Original scientific paper Memristors will surely have application in secondary lightning protection as well. This paper proposes a combined over-voltage protecting device consisting of a memristor connected in series with a spark gap. Operation of this combined device has been simulated with circuit simulation software on a model proposed in this paper. The memristor is applied for dissipating ...

Block of human ether-à-go-go–related gene 1 (hERG1) K channels by many drugs delays cardiac repolarization, prolongs QT interval, and is associated with an increased risk of cardiac arrhythmia. Preferential block of hERG1 channels in an inactivated state has been assumed because inactivation deficient mutant channels can exhibit dramatically reduced drug sensitivity. Here we reexamine the link ...

Three randomised controlled trials have shown a significant reduction in peri-operative mortality when comparing endovascular aneurysm repair (EVAR) with standard open surgery (1.7% v. 4.7% in the EVAR Trial 1; 1.2 v. 4.6% in the Dream Trial; 0.5 v. 3% in the OVER Trial1-3). EVAR has therefore become the standard of care in many centres. There are, however, patients who require EVAR because ope...

This study examines the effects of straw management and winter flooding on soil N dynamics and crop N uptake in California rice (Oryza sativa L.) systems. Experiments were established in two locations in northern California with main plot treatments being winter flooding or no flooding; and four straw management practices (burn, remove, incorporate, and roll) as subplot treatments. Fertilizer w...
