ریز کردن دانه ها روشی موثر و اقتصادی برای بهبود خواص مکانیکی مواد است. از آنجایی که کاهش اندازه دانه مواد فلزی به زیر mµ 5 با روش های متداول کارسرد و تبلور مجدد عملاً دشوار است، روش هایی جدید نظیر سینتر کردن نانو پودر ها، آلیاژ سازی مکانیکی و کریستاله کردن ساختار های آمورف سریعاً سرد شده برای تولید دانه های فوق ریز (ufg) توسعه یافتند، اما این روشها برای تولید مواد حجیم عاری از نقص با دشواری های ز...
A novel algorithmic method for weaving design is presented, inspired by the recently discovered AA Fractals. The method is capable of producing a weaving pattern from any binary sequence or pair of sequences. All generated patterns can be woven in the simplest (4-shaft) dobby looms. An algorithm for generating input binary sequences is also presented, and the sequences produced by this algorith...
This paper questions the extent to which current critical engagements with postcolonial realities may exhibit an exoticising tendency they simultaneously decry as colonialism’s orientalist reflex. Contemporary instances of the exoticization of the “other”, however, are not necessarily the result of a practice of cultural translation that becomes ‘the superimposition of a dominant way of seeing,...
The paper deals with the optimization of welding parameters of friction stir welding of different Aluminium alloy groups. For this purpose 5 series Aluminium alloy Al 5083 and 6 series Aluminium alloy Al 6062 were taken .Tensile Strength test and micro structure analysis under various rotating speeds and tool profiles is conducted. It is observed that the increase in tool rotation speed and the...

We review the relation between the matrix model and Liouville approaches to two-dimensional gravity as elaborated by Moore, Seiberg and Staudacher. Then, based on the supersymmetric Liouville formulation and the discrete eigenvalue model proposed by Alvarez-Gaumé, Itoyama, Mañes and Zadra, we extend the previous relation to the supersymmetric case. The minisuperspace approximation for the super...
Cerebral accumulation of amyloid A protein (AA) is characteristic of Alzheimer disease (AD). AA can be detected in cerebrospinal fluid and in plasma. Although plasma AA has been proposed as a marker of risk of AD, it is unknown how plasma levels relate to neuropathologic levels. We compared plasma levels of AA40 and AA42 obtained during life with biochemical and pathologic levels in frontal and...
