future of revelution is the most important issue after any revolution. considering the importance of the futue of the islamic revolation in iran and the interrational pressure agints it, the present article attempts to analyze future of the islamic revolution with serario writing method which is one of the future studies methods. having considerd several possible sevarios, the researcher showed...
Vibrations of launch vehicle conical fairings are investigated. Fairings simulated using thin conic shells. The modal analysis a elastic shell is based on the use developed finite element model an inhomogeneous shell. In general, technique makes it possible to investigate geometrically nonlinear deformation, stability, and post-buckling behavior wide class structure implemented at each step sta...
in the present study, vibration of cylindrical laminates with different layers and angles were studied. in order to actuate and polarize in radial direction, a piezoelectric layer was located at outer surface of composite shell. laminates were assumed long enough so that plane strain state analysis in 2d can be used properly. in order to satisfy the boundary conditions, variables in terms of fo...
This experiment was carried out to study the effect of different levels (3.06, 3.23, 3.4, 3.57 and 3.74%) of calcium and vitamin D3 (2000, 2200 and 2400 IU/kg diet) on eggshell quality of laying hens. In a completely randomized design and in a 5×3 (15 treatments) factorial arrangement, two hundred and forty (240) white leghorn laying hens, strain Hy-Line W36 and 26 weeks old, were divided into ...
islamic revolution of iran in 1357 united many groups,social castes and associations with different beliefs which all were oppossed to the shah’s regime. islamic revolution of iran like other revolutions did not preserve this coalition and after wining the revolution, this coalition did not continue. according to the teories of kerin berinton, after a revolution’s victory, moderates come to wor...

This fundamental change, heppenned with the presence of a mass of people and being of a continuous nature, passes a developing and transendenc-giving direction; the achievements of the revolution i...
TiO2-SiO2 core-shell particles include of monodisperse silica core and nanostructured titania shell were synthesized by a multi-step coating process. The monodisperse silica spheres were synthesized by Stöber method and titania shell was obtained of a colloidal sol prepared by a hydrolysis–condensation reaction. The titania sol was deposited on monodisperse silica spheres by a multi-step coatin...
polyvinyl ester green composites were synthesized with walnut shell powder (wsp) by in-situ polymerization technique. the green composites have been evaluated for mechanical properties such as tensile strength, tensile modulus and hardness. sliding wear loss, specific wear rate and coefficient of friction were investigated by using computerized pin-on–disc machine at normal applied loads of 20,...

The theory of diffusion is one of the prevailing theories on the explanation of the quality of dissemination of innovations, expansion of ideas and thoughts in the area of culture.The present research is an attempt to respond to this question: Is it possible to disseminate the Islamic Revolution values and ideals through the window of Abrahamic Hajj into the world of Islam? And if the res...
