although economic and managerial literature is replete with studies that probe about productivity but only a few studies decompose it to its components (technological changes, managerial efficiency changes and scale efficiency changes)and analysis their share in productivity changes (positively or negatively). accordingly, this article attempts to explain the issue by decompose productivity to ...
Background & Aims: Dental materials have had a great role in reconstruction of dental structure. One of the complications of using metallic filling in mouth is galvanic symptom. When two or several non-homogenous dental materials with different electric potentials lie near, the side effects are metallic taste feeling, irritated feeling in membrane, erythematous region, and gingivitis desquamate...
Theoretical model of x-ray scattering as a dense matter probe. Difference in X-ray scattering between metallic and non-metallic liquids due to conduction electrons. Derivation of the static structure factor in strongly coupled non-equilibrium plasmas for X-ray scattering studies.
An intelligent design method of double screen frequency selective surfaces (FSSs) is addressed in this paper. The employed unit cell is composed of two metallic screens, which are printed on both sides of a substrate. The presented non-trial-and-error approach is investigated based on the separate design of each screen. With the help of some physical intuition and an equivalent circuit model, i...
The energy absorbing capability is one of the most important aspects of crushing behavior of a structure subjected to axial impact. In this paper, a simple practical method is introduced to enhance the crushing behavior of this kind of structure. The axial impact of metallic energy absorbing thin-walled tubes with special shaped cross-section is simulated using LS-DYNA software. The effect of c...
