Buckle folds are common traps for hydrocarbon in several contractional provinces. Buckle folds form where stratified sequences rest a top salt or some other utterly weak rock as a decollemet zone in units with high competency contrasts by a compressive stress which acted along the length of the rock layers. An important parameter affecting buckle folding of a competent zone above a mobile decol...

The form and morphology criteria are among  effective components in enhancement and improvement of urban environments and one of the features of successful urban spaces, is the way these criteria are arranged alongside each other especially at the visual landscape of an entrance space, because entrance of every place is the first and most important communication ring between the person and the ...

We agree with Block’s basic hypothesis postulating the existence of phenomenal consciousness without cognitive access. We explain such states in terms of consciousness without top-down, endogenous attention and speculate that their correlates may be a coalition of neurons that are consigned to the back of cortex, without access to working memory and planning in frontal cortex. We agree with Blo...

The present article deals with the analysis of thermal-bending stresses in a heated thin annular sector plate with simply supported boundary condition under transient temperature distribution using Berger’s approximate methods. The sectional heat supply is on the top face of the plate whereas the bottom face is kept at zero temperature. In this study, the solution of heat conduction is obtained...

In Iran, new centralization characteristic, especially during Pahlavi dynasty, has been convergence and its vast use in bureaucracy. Historical sociological studies have consensus on the issues of centralization, power centralization, and political sovereignty in Iran; however, these issues have some divisional interruptions and different levels of strength in some parts of the history.

in the present study, the root vigor and kinetic characteristics of nitrogen absorption in potato cultivars was investigated through sand cultivation and pot tests with nutrient solution. four cultivars of potatoes, namely, feiwuruita, yunshu301, liangshu97, and chuanyu56 were grown in nutrient solution matrix cultures. the result showed that: (1) nitrogen uptake rates differed significantly am...
