ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...

Due to rainfall and climatic conditions, Guilan province owns several bridges from past historical periods. The present study investigates the typology and recognition of factors affecting the formation of Safavid and Qajar historical bridges in Guilan province. The research seeks to answer the following questions; which factors have been effective in the formation of different types of Safavid...

Although AI research and commercial system development depend on bodies of formally represented knowledge that are expensive and diicult to construct, current knowledge base design does not support the accumulation or reuse of such knowledge. This paper presents a strategy for building libraries of sharable, reusable knowledge in which common ontologies play a central role as a knowledge coupli...

in his last years of life americans had almost forgotton steinbeck, and those who had not, occasionally criticized him for supporting and praising the u. s. military intervention in the vietnam war. althought ateinbeck incorporates different themes into his works, each one bears many signs of his concern and sympathy for america and the american common people in particular. steinbecks to a god ...

INTRODUCTION One of the most difficult dilemmas in relationship science and couple therapy concerns the interaction between sexual desire and love. As two mental states of intense longing for union with others, sexual desire and love are, in fact, often difficult to disentangle from one another. AIM The present review aims to help understand the differences and similarities between these two ...

This paper presents a general method to automatically build large knowledge bases from online lexical resources. While our experiments were limited to generate a knowledge base from WordNet, an online lexical database, the method is applicable to any type of dictionary organized around the elementary structure lexical entry definition(s). The advantages of using WordNet, or richer online resour...

Emotion regulation is commonly characterized as involving conscious and intentional attempts to change felt emotions, such as, for example, through reappraisal whereby one intentionally decreases the intensity of one's emotional response to a particular stimulus or situation by reinterpreting it in a less threatening way. However, there is growing evidence and appreciation that some types of em...

Common bean (Phaseolus vulgaris L.) is among the most important grain legumes for human consumption worldwide. Portugal has a potentially promising common bean germplasm, resulting from more than five centuries of natural adaptation and farmers' selection. Nevertheless, limited characterization of this resource hampers its exploitation by breeding programs. To support a more efficient conservat...

In this paper, we investigate duality of modular g-Riesz bases and g-Riesz bases in Hilbert C*-modules. First we give some characterization of g-Riesz bases in Hilbert C*-modules, by using properties of operator theory. Next, we characterize the duals of a given g-Riesz basis in Hilbert C*-module. In addition, we obtain sufficient and necessary condition for a dual of a g-Riesz basis to be agai...
