extended interaction oscillators (eio) are vacuum electronic sources of microwave, millimeter-wave and terahertz radiations. in this paper, eio is investigated by using a circuit model. the value of the coupling element in the model is evaluated from the near band-edge dispersion characteristics of the rf structure. the end external loading of the interaction structure is equivalently modeled b...

change and order have been the central subjects of masters of social thought and historical sociology in the modern age. moreover, explanation of these phenomena has evolved from a naturalistic perspective and negation of agency to an approach emphasizing agency and structure and their mutual interaction. based on a theoretical framework, this article aims to compare shahid motahari’s thought r...

in this study, the effective parameters on the inelastic response of asymmetric buildings is evaluated for an ensemble of real iranian earthquake records by considering soil-structure interaction. then, the design eccentricity obtained from the inelastic dynamic soil-structure analysis is compared with the design eccentricity of seisimic codes of iran, atc-3, new zeland, canada, mexico, austral...

leadership style and organizational climate are considered as a substructure framework in successful performance of knowledge management. the purpose of this research is investigating both the effect of leadership style and organizational climate on knowledge management and the moderate role of organization structure and social interaction in affecting leadership style and organizational climat...

thermal conformational changes in human serum albumin (hsa) in present with a 10 mm phosphate buffer, at ph=7 have been investigated via circular dichroism (cd) and uv spectroscopic methods. the results indicate that temperature in a range of 25oc to 55oc could induce a reversible conformational change in the structure of hsa. the hsa phase transition corresponds to the physiological and pathol...
