Since 1999 we have participated in a major project sponsored by National Natural Science Foundation of China (NSFC), which aims to explore the macroeconomic system problems by meta-synthesis systems approach (MSA) proposed by Chinese system scientist Qian Xuesen (Tsien HsueShen). It is found that the oriental Wu-li Shi-li Ren-li system approach may be applied to describe the working contents an...
Background: Li-Fraumeni syndrome (LFS) is one of the most serious hereditary cancer syndromes with a high risk of malignancy in childhood. This syndrome is an autosomal dominant cancer predisposing syndrome due to a germline mutation in the TP53 tumor suppressor gene. Methods: In this study, a representative family case of Li-Fraumeni syndrome is described. The proband of this family ...
هدف این پروژه، سنتز ترکیبات جدید فروسنیل- و دی فروسنیل بوران بود. واکنش بین ترکیب 1و ترکیبات ارگانو لیتیم مانند c9h7li ,me3sich2li ,mes li ,dur li با نسبت های مولی متفاوت منجر به تشکیل ترکیبات فروسنیل بوران 7-2 می شوند. علاوه بر این، از واکنش بین ترکیب 1 و تری اتیل سیلان ( (et3sih ترکیب دی فروسنیل بوران 8 سنتز شد. ترکیبات 10 و 12 نیز از واکنش بین ترکیب 8 و مزیتیل آلکینیل لیتیم و 2 – مرکا...
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
In this text we prove that in generalized shift dynamical system $(X^Gamma,sigma_varphi)$ for finite discrete $X$ with at least two elements, infinite countable set $Gamma$ and arbitrary map $varphi:GammatoGamma$, the following statements are equivalent: - the dynamical system $(X^Gamma,sigma_varphi)$ is Li-Yorke chaotic; - the dynamical system $(X^Gamma,sigma_varphi)$ has an scr...
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
if the precise implementation of the principle of proportion and:balance between the violation and the penalty as well as the other dimensions could be considered as a stick yard for the imptementation of justice any lack of preciseness in carrying out such principle would not indeed be much too far from injustice . naturally ,if it would be imagined that the objective of balance between...
جذب نیتروزآمین روی مدل های کلاستر 5t و 10t کاتالیزور h-zsm-5 و بر روی شبکه 10t کاتالیزور li-zsm-5 به صورت نظری به وسیله ی روش های شیمی کوانتوم بررسی شد. کمپلکس na-5t(h) در سطوحb3lyp/6-31++g(d,p) و oniom(b3lyp/6-311++g(d,p):hf/3-21g*) وoniom(b3lyp/6-311++g(d,p):hf/6-311+g(d)) و کمپلکس های na-10t (h) درسطوح oniom(b3lyp/6-311++g(d,p):hf/3-21g*) و oniom(b3lyp/6-311++g(d,p):hf/6-311+g(d)) و oniom(mp...
a simple and efficient method for the synthesis of quinolines and polycyclic quinolines using li+ modified nanoporous na+-montmorillonite is described. this new nanocatalyst proceeds via friedlander annulation under solvent-free conditions. it describes our observations about a trend of catalytic activity of lithium cation in nanoporous na+-montmorillonite. in this study, several types of 1,3-d...
