Collecting information about molecular organisation on biological materials such as bone and dentin represents a major challenge in attaining better understanding of their mechanical properties. To that end, solid state Nuclear Magnetic Resonance (ssNMR) spectroscopic study is an appropriate strategy to provide atomic structural details these amorphous composite materials. However, species like...

in this paper, we study different methods of solving joint redundancy-availability optimization for series-parallel systems with multi-state components. we analyzed various effective factors on system availability in order to determine the optimum number and version of components in each sub-system and consider the effects of improving failure rates of each component in each sub-system and impr...

given the importance of innovation in a stormy environment with ongoing changes for the organizations, in this study, to identify a noteworthy aspect of community change from the viewpoint of organizational behavior we attempt to examine social capital of employees in an involved organization in change. the aim of this study is to evaluate the impact of social capital components (cognitive, ele...
