the main role ofcore in earth dams is to reduce and control the seepage flow through the dam. in order to achieve this purpose, the core material is usually selected from pure or mixed clays.due to very small coefficient of permeability, the clay cores can prevent water leakageeasily. however, pore water pressures developed inside the core during construction, can not be dissipated quickly. as ...

The parameters of the constitutive model, the creep model, and the wetting model of materials of the Nuozhadu high earth-rockfill dam were back-analyzed together based on field monitoring displacement data by employing an intelligent back-analysis method. In this method, an artificial neural network is used as a substitute for time-consuming finite element analysis, and an evolutionary algorith...

30 Abstract—The blessings of hyperspectral remote sensing are manifold and it has enabled researchers to locate, map and identify different materials on the surface of Earth. Hyperspectral remote sensing play a key role in mineral mapping activities and it can be a much powerful and cost effective tool for mineral development activities in a developing country like Pakistan where there are rich...

This paper introduces an accurate, fast, and applicable method for optimization of slip surfaces in earth slopes. Using Genetic Algorithm (GA), which is one of the modern and non-classic optimization methods, in conjunction with the well -known Bishop applied method, the optimum slip surface in an earth slope is investigated and its corresponding lowest safety factor is determined. Investigati...

effects of lamb and parents coefficient of inbreeding (ci) on wool weight were studied using 10,868 wool records belonging to 3,244 iran black lambs (1,633 males and 1,611 females) representing 96 rams and 995 ewes collected during 1983-2006 from animal breeding station of abbas abad. year and month of shearing, ci of lamb and dam, sex and birth type had significant affect on wool weight among ...

BACKGROUND Echinococcus granulosus is a cestode whose larval stage causes cystic echinococcosis in wild animals, livestock, and human. OBJECTIVE The aim of this study is to highlight the seroepidemiology of E. granulosus infection and surgical cases in the general population of Khorram Abad district, southwest of Iran. MATERIALS AND METHODS Anti-E. granulosus antibodies were tested in 617 i...
