Abstract Earthquake is one of the horrible natural disasters. With considerable developments in constructional science, experts have been able to find out factor forces that cause earthquakes damage and destructions different types buildings, including residential commercial caused by earthquake are high importance need be considered. The multi-story buildings usually weak points building, whic...

abstract: in this paper, an exergy analysis approach is proposed for optimal design of distillation column by using simulated annealing algorithm. first, the simulation of a distillation column was performed by using the shortcut results and irreversibility in each tray was obtained. the area beneath the exergy loss profile was used as irreversibility index in the whole column. then, first opti...

We report on ASCA, RXTE, and archival observations of the high mass X-ray binary pulsar 4U1907+09. Spectral measurements of the absorption and flux were made at all phases of the X-ray pulsar orbit, including the first spectral measurements of an extended period of low flux during two of the ASCA observations. We find that a simple spherical wind model can fit the time averaged light curve as m...

Horwich (Mind 123(491), 2014) has argued that only someone with inflationary tendencies could feel inclined to endorse truth relativism. In doing so, he argues deflationism about entails the denial of If sound, Horwich’s argument entail relativism is incompatible any conception our ordinary predicate according which there some sort equivalence between a ground-language claim p and corresponding...

short story is built on a single story that have a single impact and it is a short detail of human life.the length of the short story and the time to read does not take from the listener and the reader but a short time. and that is one of the updated arts that have emerged in the modern era and arabs did not know this kind of story in past ages and it has no roots in the heritage of storytellin...
