Computed tomography studies and histological analyses were performed on the mummified remains found in Chehrābād salt mine northwestern Iran. The ancient mummies are dated to Achaemenid (550–330 BC) Sassanid (3rd–7th century AD) time period died mining incidents. aim of study was describe radiological findings several Iranian with special interest pathological postmortem changes. show multiple ...

Original scientific paper RC frame structures with specially shaped columns and RC frame structures with rectangular columns are different types of structures with different column sections. A progressive collapse analysis model of RC frames was proposed using the beam-column element and joint element based on the program OpenSees. Progressive collapse performance of the experimental frame was ...

In recent years, rehabilitation has been the subject of extensive research due to increased spending on building work and repair of built works. In all cases, it is absolutely essential to carry out methods of strengthening or repair of structural elements, and that following an inspection analysis and methodology of a correct diagnosis. The reinforced concrete columns are important elements in...

Today, due to the complexity of engineering problems and at the same time the advancement of computer science, the use of machine learning (ML) methods and soft computing methods in solving engineering problems has been considered by many researchers. These methods can be used to find accurate estimates for problems in various scientific fields. This paper investigates the effectiveness of the ...

Several deficient steel structural members require to be strengthened all over the world. In this article, horizontal defects were generated at three locations (top, middle, and bottom) on the middle element and the middle of the side element. Consequently, the effects of the location of such defects on axial behavior of Carbon Fiber Reinforced Polymer (CFRP) strengthened steel Square Hollow Se...

Designed especially for capillary electrochromatography (CEC), silicate-entrapped columns are made by trapping particles of chromatographic packing material in a network of silica. Once entrapped, the capillary no longer requires frits. This renders a more homogeneous and stable packed bed. Accidental breakage of the fragile frits is not an issue with these robust columns. Columns packed with r...

The cortical column hypothesis is described along with backing evidence. Proposals for the functional properties of columns are reviewed, namely those based on construction of columnar models and networks of columns. An attempt is made to tie this knowledge into that of an existing model of planning, the TELOS model.

on the one hand, the vacant position of study about impact of achaemenid empire on eastern states is due to silence by classic authors in dealing with these lands; and on the other hand, it is reffered to shortage of archeological artifacts relating to achaemenids at the given region. in the present essay, by the aid of reminiscent works and economic and administrative evidences obtained from e...
