this research has been done for aim assessing of structural factors and environmental non-governmental organizations performance is descriptive – surveying. statistical population is consisted of all members of environmental non- governmental organizations in khuzestan province(n=359) that using cochran formula, 90 members were chosen and examined through the proportional stratified random samp...

an analytical nonlinear stress-strain model and a microscopic damage index for confined and unconfined concretes together with a macroscopic damage index for reinforced concrete (rc) structures under cyclic loading are proposed. in order to eliminate the problem of scale effect, an adjustable finite element computer program was generated to simulate rc structures subjected to cyclic loading. by...

in order to achieve educational purposes and having better spiritual power in an education institute, the authorities must try to keep and support their human recourses. this study is conducted to determine the affective motivation factors on retension of faculty members at hormozgan university of medical sciences (hums). for this purpose, the view points of 71 faculty member’s (hums) through a...

Concrete filled tube (CFT) columns have been used as primary axial load-carrying members in high-rise building especially in seismic zones. The structural member has become popular as it has a number of distinct advantages over an equivalent steel, reinforced concrete, or steel-reinforce concrete structural member. This paper is intended to presents numerical modeling of elliptical concrete-fil...

Automation is being increasingly explored as a possible solution for safely increasing productivity in structural steelwork erection. A piece of automation equipment such as a robotic crane has no intrinsic knowledge of the steel erection process it automates. Thus, geometric and spatial information about a steel member and the motion sequences that must be executed to move that component from ...

The design of upholstered sofa frames to meet the General Service Administration (GSA) performance test regimen requires that analytical method and design loads be available. A simplified analysis method using beam models to analyze and calculate bending moments of critical structural members in a three-dimensional sofa frame was explored. The GSA performance test regimen load schedules were ap...

A total synthesis of the cyanobacterial natural product nostodione A is reported involving a convergent, diversity-oriented route, enabling the assembly of a mini-library of structural analogues. The first single crystal X-ray structural determination on a member of this series is reported along with SAR studies identifying potent inhibitors of invasion and replication of the parasitic protozoa...
