Controlling crystal nucleation and growth leading to formation of nano structures by an original flux treatment method mainly in calcia and magnesia crucibles followed by water-cooling allowed production of Ti45Cu45Fe10 bulky nanostructured alloy of 16mm in diameter. Since a glass forming ability (GFA) of the alloy composition is low, the alloy could not form an amorphous structure even by a co...
The microstructure of a melt-spun Zr28Ni44Cu28 (at. %) alloy was characterized in order to determine the structures and compositions crystalline phases that compete with glass formation during rapid solidification. Two were identified, namely, face centered cubic (FCC) zirconium oxide phase primitive version big-cube phase, using combination scanning electron microscopy, energy dispersive X-ray...
In this paper, we propose and analyze a proxy-based hybrid cache management scheme for client–server applications in Mobile IP (MIP) networks. We leverage a per-user proxy as a gateway between the server and the mobile host (MH) such that any communication between the MH and server must pass through the proxy. The proxy has dual responsibilities in our design. It keeps track of the current loca...
The characterization of strain rate effects near glass transition temperature (Tg) gives important information on flow behavior metallic glasses (MGs). For this purpose, the tensile jump test was carried out to evaluate behaviors ZrCoAl(Si) MG ribbons. primary thermal analyses showed that Si minor addition into ZrCoAl alloy leads betterment stability and forming ability (GFA), correlated with s...
این پژوهش با هدف بررسی ساختار عاملی و ویژگی های روان سنجی (روایی و پایایی) مقیاس تنهایی کودک میان دانش آموزان دورۀ راهنمایی اجرا شد. روش پژوهش همبستگی (سنجش روایی و پایایی) و جامعۀ آماری پژوهش شامل دانش آموزان مقطع راهنمایی شهر تهران در سال تحصیلی 91ـ1390 بود که از میان آنها 410 نفر به شیوۀ نمونه گیری تصادفی خوشه ای انتخاب شدند. ابزار پژوهش شامل مقیاس تنهایی کودک (آشر و ویلر، 1985) و مقیاس عزت ...
Selective cyclooxygenase inhibitors have attracted much attention in recent times in the design of new non-steroidal anti-inflammatory drugs (NSAID). 3D-QSAR studies have been performed on a series of 1,5-diarylpyrazoles that act as selective cyclooxygenase2 (COX-2) inhibitors, using three different methods: comparative molecular field analysis (CoMFA) with partial least squares (PLS) fit; mole...
Self-assembled nano-micelles of amphiphilic polymers represent a novel anticancer drug delivery system. However, their full clinical utilization remains challenging because the quantitative structure-property relationship (QSPR) between the polymer structure and the efficacy of micelles as a drug carrier is poorly understood. Here, we developed a series of QSPR models to account for the drug lo...
Circles of Care grantees were provided the opportunity to develop a locally relevant definition of serious emotional disturbance that would be used to define what type of emotional, behavioral, and mental disability would be required to receive services. After conducting detailed assessments of the definition in the guidance for applicants GFA and the definitions used by others in their respect...
