Microwave sintering is a new sintering technology developed in the middle to late period of the 1980’s, which is characterized by fast densification for ceramic materials[1]. In recent years, microwave heating has been well employed in the field of sintering and joining of ceramics as a result of its advantages against conventional methods. These ceramic materials include oxides, mixed oxides, ...
j 6=i Aj . We let ai denote a pure action for player i, and let si ∈ ∆(Ai) denote a mixed action for player i. We will typically view si as a vector in R Ai , with si(ai) equal to the probability that player i places on ai. We let Πi(a) denote the payoff to player i when the composite pure action vector is a, and by an abuse of notation also let Πi(s) denote the expected payoff to player i when...
اکسیدهای پلی وینیل پیریدین poly (vinylpyridine n-oxides) قبلا" ساخته و مورد مطالعه قرار گرفته اند. مطالعات نشان دهنده فعال بودن این نوع بیوپلی مرها در مقابل بیماری (silicosis) بوده است . در این کار تحقیقی برای پیشبرد مطالعات در مورد بیوپلی مرهای جدید ضد (silicosis) اکسید وینیل پیریمیدین poly (4-vinylpyrimedine n-oxide)(xiv) طی چندین مرحله واکنش ساخته و مطالعه شده است . منحنی تغییرات ویسکوزیته ن...
Mn/Pb and Mn/Ni mixed oxide were prepared at ambient temperature by reduction of KMnO4 with Mn, Pb, and Ni salts. This low-temperature approach provides amorphous structure of the active material. The specific capacitance of pure MnO2 was estimated to be 166 F/g and increased to 210 and 185 F/g for Mn/Ni and Mn/Pb oxides, respectively. The carbon loading was optimized at 20 wt %. Based on a sin...
Mixed crystals can be categorized as the crystal in which two or more different types of atoms are present and configured. These atoms interact each other in the influence of Coulomb force of attraction and the presence of short range repulsion force. Due to this interaction they tends to be arranged in equilibrium state and forms new material. A pure crystal can be doped by impurities with pro...
BACKGROUND Progressive graft dysfunction (GDF) and loss of insulin independence (II) have been invariably observed in islet transplant recipients under the "Edmonton protocol." To reestablish II, we performed supplemental islet infusions (SI) in recipients of allogeneic islet transplant alone, displaying GDF. To improve the engraftment and long-term graft function of SI, exenatide (EXN) and eta...
Teachers can influence the complex process of learning in education, in general, and in second/foreign language (L2) learning in particular. In this light, understanding the factors influencing teachers’ pedagogical success can help L2 teachers achieve more effective teaching. This study then investigated the role of spiritual intelligence (SI) in L2 teachers’ pedagogical success. In so doing, ...
Porous Si/Cu6Sn5/C composite containing native oxides was prepared via solid-state mechanical milling and wet chemical etching. This used as anode material for Li-ion batteries. X-ray diffraction, scanning electron microscopy, 119Sn Mössbauer spectroscopy, photoelectron spectroscopy show that the has a pitaya-like morphology based on porous Si embedded Cu6Sn5 non-porous microparticles with surf...
UNLABELLED BACKGROUND In the present study, chemical consistency between traditional and dispensing granule decoctions of Tao-Hong-Si-Wu decoction was rapidly evaluated by UPLC-QTOF-MS coupled with the MarkerLynx software. Two different kinds of decoctions, namely traditional decoction: water extract of mixed six constituent herbs of Tao-Hong-Si-Wu decoction, and dispensing granules decoctio...
In the present work, ZnO/Bi2O3, SnO2/Bi2O3/Bi2O4 mixed oxide, Bi2O3 rod-like and SnO2 nanoparticle have been synthesized. The obtained samples were characterized by field emission scanning electron microscopy (FE-SEM) and X-ray diffraction (XRD). The optical properties of samples were evaluated by UV-Vis spectrophotometer. The photocatalytic activity of samples was evaluated by decolorization o...
