Participation has been with us since the inception of living in a family. Participation developed in the matrix of religion and, two centuries ago, opend up its way in political systems of European countries. It supported the democratic principle of people's determining their own destiny. Today, participation is considered a necessity for the total development of not only individuals, but also ...

M Rahmani Y Mohammadi,

This study is limited to study of buckling analysis of a sandwich cylindrical shell with functionally graded face sheets and homogenous core. High-order sandwich plate theory is improved by considering the in-plane stresses of the core that usually are ignored in the analysis of sandwich structures. Assume that all properties of the face sheets and the core are temperature dependent. Strain com...

The aim of this study is synoptic analysis of heavy precipitations in Kurdistan Province during 1/1/1961 to 31/12/2010(18263days). By using two thresholds of extensively and intensity of precipitation, 107 days have been recognized. In temporal view, the selected days occurrences in wet seasons of year that start from October to June. By applying the principle component analysis on the sea leve...

A bioinformatics method was used to analyze F/10 and G/11 xylanase basing on principle component analysis, and a model was made to classify between these two folds with an ideal result. The principle components were predicated to be secondary structures, the components were analyzed with the architecture of each family, and found comparable with (beta/alpha)(8)-barrel of F/10 xylanase and right...

The goal of this research was to extract criteria for evaluating technology leaders and it was conducted by mixed method.  The research method was descriptive in the qualitative part and survey method in the quantitative part.  The research was carried out in smart and semi-smart  primary schools in Zanjan province in the academic year of 1398-99. Participants of the qualitative part were fifte...

Our theory provides an unambiguous definition of dominant designs (stable core components that can be stable interfaces) and the inclusion of multiple levels of analysis (system, subsystems, components). We introduce the concept of an operational principle and offer a systematic definition of core and peripheral subsystems based on the concept of pleiotropy.

For ranking and grouping of full-sibs and hybrids of sugar beet obtained from breeding programs, two separate experiments were carried out at the farm of the Agricultural and Natural Resources Research Station of Miandoab in 2017 under saline and normal conditions. For this purpose, 17 full-sibs and 28 hybrids differing in resistance and susceptibility to environmental stresses were investigate...

We study the PageRank mass of principal components in a bow-tie Web Graph, as a function of the damping factor c. Using a singular perturbation approach, we show that the PageRank share of IN and SCC components remains high even for very large values of the damping factor, in spite of the fact that it drops to zero when c → 1. However, a detailed study of the OUT component reveals the presence ...
