در سالهای اخیر تلاش زیادی برای سنتز کمپلکس های سوپرامولکول و پلیمرهای کوئوردیناسیونی بر مبنای لیگاندهای آلی چند دندانه شده است. این مواد به دلیل داشتن خواص منحصر به فرد، کاربردهای زیادی در صنعت دارند. سنتز پلیمرهای کوئوردیناسیونی جدید از سرب(ii) در ابعاد بالک(توده) و نانو با استفاده از روش گرادیان دمایی و به روش شاخه جانبی صورت گرفته و با روش طیف سنجی ir و پایداری گرمایی آن ها توسط آنالیزهای وز...
abstractderivative action is an action filed by shareholders against corporatedirectors in order to recover corporate’s rights. this mechanism is set up tohave the directors answerable for their failure in carrying out their duties.prior to the ca 2006, foss v. horbottle rule deprived shareholders of takingany action against directors but in exceptional cases. acknowledging theright of filing d...
starting from the 6th century a.h., and especially starting from the mongol era onward, along with the flourishing of historiography, historical shāhnāmeh-composition also became a point of interest, and shāhnāmehs appeared with the aim of recording historical events. in the composition of these shāhnāmehs, ferdowsi’s shāhnāmeh was like a model for the shāhnāmeh-writers, and due to this the spi...
This papers considers the Benford distribution as one the interesting rules of probability theory. This rule shows that, despite of usual underestanding about the uniform distribution of digites for lieing on different positions in numbers, digits are distributed according to an non uniform distributions for numbers araising from many natural phonemena. Benford distribution proposes ...
Sometimes conventional feedback controllers may not perform well online because of the variation in process dynamics due to nonlinear actuators, changes in environmental conditions and variation in the character of the disturbances. To overcome the above problem, this paper deals with the designing of a controller for a second order system with Model Reference Adaptive Control (MRAC) scheme usi...
Under theenforcing the law on damage, when patients are exposed to damage and injury when acting or leaving action on health-related factors such as physicians and laboratory officials, patients must take standard action to mitigate the loss or claim. Otherwise they will lose the right to defend themselves. The most important effect of this rule is that the assignment of a claim against a loss ...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
Research on the anomalous Hall effect (AHE) has been lasting for a century to make clear underlying physical mechanism. Generally, AHE appears in magnetic materials, which extrinsic process related scattering effects and intrinsic contribution connected with Berry curvature are crucial. Recently, counterintuitively observed nonmagnetic topological materials attributed existence of Weyl points. ...
the application of a comprehensive model of communicative language ability (cla) to language teaching and testing has always been an imperative in l2 education since hymess proposal of communicative competence in the 1970s. recent l2 research has clearly underscored the importance of sufficient pragmatics representation as an essential component of cla in pedagogical and testing practices in l2...
