The aim objective of this study is to investigate the effects of near-field earthquakes on the response of mid-rise buildings with tubular structure.  For this purpose, a 20-story building with a square plan of six by six bays, all with 6 m span, and story height of 3.70 m is considered.  Axial force of columns, shear lag, and inter-story drift values are used as the main response parameters. N...

The understanding of the dynamic behavior of distillation columns has received considerable attention because distillation is one of the most widely used unit operations in chemical process industries. This paper reports a dynamic simulation study of the possible distillation columns sequences of Dew pointing unit in the second phase of South Pars Gas Refinery. In this unit, three columns are u...

Abstract The war between Assyria and Egypt resulted in the deportation of scholars from Nile Valley to Mesopotamia. Among them were so-called “snake charmers.” While it was a well-known profession Egypt, this not case or Babylonia, where treatment snakebites scorpion stings left exorcist doctors. A number clues late Neo-Assyrian Achaemenid Persian periods suggest that charmers” enjoyed success ...

Abstract After an overview of the multilingual epigraphy Daskyleion during Achaemenid period, this paper focuses on closing formula shared by Aramaic KAI 318 and Old Phrygian B-07 epitaphs, which consists a warning not to harm funerary monument. Comparison two inscriptions sheds light cryptic B-07, sole epitaph known. As result, provides new forms, like possible first-person singular umno=tan ,...

Maintaining the levels of nitrogen in agricultural fields to ensure crop yield performance is challenging due to the complex dynamics of nitrogen transformation in soil. Nitrogen is mainly taken up by plant roots in the form of nitrate, but it is considered as an environmental pollutant that threatens human and animal health. Therefore, it is necessary to use adsorbent compounds to retain nitra...

in this paper a discrete big bang-big crunch algorithm is applied to optimal design of reinforced concrete planar frames under the gravity and lateral loads. optimization is based on aci 318-08 code. columns are assumed to resist axial loads and bending moments, while beams resist only bending moments. second-order effects are also considered for the compression members, and columns are checked...

this research includes both experimental and cfd investigation in the hydrodynamic behavior of a new type of column tray introduced as “concap” tray. the proposed column tray is used in contactor columns especially in stripping columns. the hydrodynamics of this concap tray is investigated in a 1.2m in diameter column. using air-water system, the experiments were performed for different liquid ...
