UNDERGROUND STRUCTURES OF THE DEMOCRATIC STATE

Numerical Modelling of the Segmental Lining of Underground Structures

There are several methods for analysing the behaviour of underground structures under different loading conditions. Most of these methods have many simplifications; therefore, in some cases, the results are too conservative and a very high safety factor, usually of more than 2 is needed. On the other hand, for stability analysis and the designing of support systems, these methods consider segme...

the role of task-based techniques on the acquisition of english language structures by the intermediate efl students

this study examines the effetivenss of task-based activities in helping students learn english language structures for a better communication. initially, a michigan test was administered to the two groups of 52 students majoring in english at the allameh ghotb -e- ravandi university to ensure their homogeneity. the students scores on the grammar part of this test were also regarded as their pre...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Jabri , the theory of state: the social power and ideal of democratic changes

  Mohammed Abed al-jabri has advanced tow main projects in his intelectual endeavours: first, an anattempt to study and reveal, as he say, Arab-islamic reason, second to propuse ideas to  restrucutring it with an aim for political changes in The line of democratic order. In this propuse, he confronts, both directly and idirectly, with a theory of state. This research deals with consisteney of...
