Background and Aim: The intellectual structure of knowledge and its research front can be identified by co-word analysis. This research attempts to reveal the intellectual structure of knowledge in information behavior inquiries, via co-word, network analysis, and science visualization tools. Methods: Bibliometric methodology and social network analysis are used. Population comprises 2146 recor...

in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...

Purpose: The aim of this study is to identify the components affecting information seeking behavior and to measure their impact from Persian and English articles in this field. In addition, the moderating variables affecting information seeking behavior were identified and their effect size was calculated. Method: The method of this study is meta-analysis. The research population included all ...

Introduction: Information behavior in knowledge and information science is seen as a fundamental human behavior that has been studied extensively thus far. This study include different approaches and perspectives that examined information behavior. The purpose of this article is to investigate the paradigm shift in information behavior by using the texts of this research ground. Methodology: Th...

we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...

abstract this study investigated the predictability of variables from a motivational framework as well as individuals qualities to predict three non-linguistic outcomes of language learning. gardners socio-educational model with its measures has been used in the current study. individual qualities presented in this study include (1) age, (2) gender, and (3) language learning experience. the...
