there are three main ideas about relation between creatures and god. one of them is the theory of separation, according to this theory there's not any homogeneity between creatures and god it means the essence and existence of creatures are completely inhomogeneity with god's essence and existence. the second is the theory of oneness, according to this theory creatures and god are uni...

leadership studies is a new interdisciplinary field of organization studies that is growing at a steady rate all over the world. leadership studies are seen as a branch of management and organization sciences despite its philosophical roots that can be traced back to plato’s philosophical writings such as laws, politics, or the republic. starting from burns’ seminal book, leadership (1978), and...

nuclear level densities and spin cut-off factors have been deduced for nuclei in the mass region 24‹a‹63,from a microscopic theory, which includes nuclear pairing interaction. single particle levels for both seeger and nilsson potentials were used in the calcdations. level densities extracted from the theory are compared with their conesponding experimental values, it is found that the overall ...

today’s organizations, in chaos, complexities, diverse, dynamic, uncertainties, and rapid and increasingly changes in technologies, markets, and life qualities, are forced to search of leaders who having the least mistakes in their decision-makings; the leaders who make the right decisions with a calculative and scrupulous sense, and serve right and suitable behaviors for guiding and leading th...

our main aim in this article is to analyze the two concepts “proposition” and “state of affairs”. first we present the minimal expectations of a theory of “proposition” and a theory of “state of affairs”, and then we turn to the views of the contemporary theorist john pollock regarding these two topics and present the most important of his views on the subject. subsequently, we reconstruct a th...

In the present study, the buckling analysis of single-walled carbon nanotubes (SWCNT) on the basis of a new refined beam theory is analyzed. The SWCNT is modeled as an elastic beam subjected to unidirectional compressive loads. To achieve this aim, the new proposed beam theory has only one unknown variable which leads to one equation similar to Euler beam theory and is also free from any shear ...

The theory of constraints is an approach to production planning and control that emphasizes on the constraints to increase throughput by effectively managing constraint resources. One application in theory of constraints is product mix decision. Product mix influences the performance measures in multi-product manufacturing system. This paper presents an alternative approach by using of goal pro...
