Schwab's Practical Theory: Integrate of Theory and Practice

The emergence of re-conceptualism in the field of curriculum studies caused a large rotation of identity in this field. The book titled "understanding of curriculum" by William Pinar may be considered the most outstanding work in the field. In this book, movement which affected pre re-conceptualist, are introduced as the traditional type and it is believed the new curriculum discourses should b...

Wave Propagation in Rectangular Nanoplates Based on a New Strain Gradient Elasticity Theory with Considering in-Plane Magnetic Field

In this paper, on the basis of a new strain gradient elasticity theory, wave propagation in rectangular nanoplates by considering in-plane magnetic field is studied. This strain gradient theory has two gradient parameters and has the ability to compare with the nonlocal elasticity theory. From the best knowledge of author, it is the first time that this theory is used for investigating wave pro...

A Study on Scientific Community of Social Sciences Professors Relying on Bourdieu’s Field Theory

Since Science is a social phenomenon, active groups of actors in a scientific field are called scientific community. The relationship between scientific capital and scientific community constructs the subject matter of current paper which is addressed through Pierre Bourdieu’s field theory and his theory of Habitus. Scientific community of sociology in various universities of Tehran were select...

Stability of higher derivative modifications of Einstein - aether theory

A time-like unit vector field is used to generalize Einstein's gravity. The resulting theory, called the Einstein-aether theory, consists of a minimal coupling between an aether field and gravity. Inspired by the Bopp-Podolsky electrodynamics, which is well-known for removing the singularity at the point charge, we generalized the Einstein-aether theory by adding such a higher order self-intera...

Nonlocal elasticity theory for static torsion of the bi-directional functionally graded microtube under magnetic field

The microtubes are important structures in nano electromechanical system .in this study a nonlocal model is presented to investigate the static torsion behavior of microtubes made of bi-directional factionally graded material (BDFGM) subjected to a longitudinal magnetic field. Mechanical properties of BDFGM microtube varies in the radial and longitudinal direction according to an arbitrary func...
