هیدروفرمینگ لوله به‌طور گسترده، در تولید قطعات ساختاری اتومبیل استفاده می‌شود. یکی از خصوصیات تولید‌شده با این فرایند، نسبت استحکام به وزن بالا می‌باشد. لولۀ فشار پایین، روش‌های پیشنهاد‌شده برای حل مشکلات قبیل نیاز بالای سیال و آب‌بندی روش انجام پایین لوله، شبیه فشردن جسم جامد است آن برخلاف بالا، قالب بالایی طول فرایند ثابت نبوده هم‌زمان اعمال داخلی حرکت کرده را تحت قرار می‌دهد. مقاله، لوله‌های...

Realizing the benefits of SDN for many network management applications (e.g., traffic engineering, service chaining, topology reconfiguration) involves addressing complex optimizations that are central to these problems. Unfortunately, such optimization problems require (a) significant manual effort and expertise to express and (b) non-trivial computation and/or carefully crafted heuristics to ...

The spatial and temporal variation of SOL cluster bacteria was assessed in oligomesotrophic Lake Mondsee and adjacent lakes by fluorescence in situ hybridization over two annual cycles. The filamentous SOL bacteria were present in Lake Mondsee throughout the study period, and the seasonal dynamics of the SOL community were remarkably similar with respect to both abundance and composition in the...

Elastases in cystic fibrosis (CF) pulmonary fluids damage lung tissue and perpetuate cycles of infection, inflammation and injury. Elastases from three different sources may be present in CF airways: neutrophils, macrophages and Pseudomonas. We measured how well the cephalosporin-based antielastase L-658,758 blocks the activity of human neutrophil elastase (NE), human proteinase-3, human macrop...

Solid dispersion formulations made of itraconazole (ITZ) and Soluplus® (polyethylene glycol, polyvinyl acetate and polyvinylcaprolactame-based graft copolymer abbreviated SOL) were produced using hot melt extrusion. Since ITZ possesses a water solubility of less than 1ng/mL, the aim of this work was to enhance the aqueous solubility of ITZ, and thereby improve its bioavailability. The three for...

The neurotransmitter glutamate mediates excitatory synaptic transmission by gating ionotropic glutamate receptors (iGluRs). AMPA receptors (AMPARs), a subtype of iGluR, are strongly implicated in synaptic plasticity, learning, and memory. We previously discovered two classes of AMPAR auxiliary proteins in C. elegans that modify receptor kinetics and thus change synaptic transmission. Here, we h...

It has been shown that cat soleus (SOL) forces remain nearly constant despite increases in electromyography (EMG) activity for increasing speeds of locomotion, while medial gastrocnemius (MG) forces and EMG activity increase in parallel. Furthermore, during jumping, average cat SOL forces decrease, while average EMG activity increases dramatically compared with walking conditions. Finally, duri...

به دنبال شیوع ویروس کرونا در جهان، بسیاری از تعاملات رسمی آموزشی سمت برگزاری بستر محیط مجازی سوق یافت و ادامة فرایند آموزش معماری نیز همانند همة دوره‌های آموزشی، دلیل تعطیلی دانشگاه‌ها، تنها برخط ممکن گشت. این میان کارگاه‌های طراحی معماری، منزلة کانون ویژگی‌های منحصربه‌فردی دارند که را سایر رشته‌های دانشگاهی جدا کرده است. نمونة بارزی یک مشارکتی، چندحسی، تجربه‌گرای مبتنی بر مسئله همین ویژگی‌ها م...
