This paper is on the elasto-plastic analysis of plane stress problems. A five-parameter yield surface is presented. This yield criterion uses associate flow along with mixed hardening rule. The analytical formulations are written and related computer program for non-linear analysis is prepared. Finally, based on the formulations, numerical examples are solved.

The configuration and safety factor of rockfill dams design depend on materials used in construction the dam. In some regions, available for using as impermeable element dam body are dispersive it is inevitable to consider dispersivity material construction. Internal erosion through cracks or other openings embankment most concern soils. authors have designed an by soil East Africa after finali...

In this paper, thermophysical analyses were achieved for the mixture of (Fe3O4-acetone/ZnBr2) refrigeration working solution and examine its efficiency characteristics as a nanoferrofluid use in absorption applications driven by different low temperatures sources. Where it shows an investigation chosen containing preparation, stability, structure, properties. The reasons behind choosing Fe3O4 n...

ramadan fasting is prescribed by quran for every able‐bodied, adult muslim and is considered an obligatory act of worship. during ramadan, the majority of muslims eat two major meals- one before dawn (sahar) and another immediately after the sunset (iftar). islamic fasting, due to its particular nature, may cause metabolic and hormonal changes in the body, which are different from those in regu...

Abstract Vanadium dioxide (VO 2 ) has demonstrated highly potential for smart windows because of its thermochromic property. This study represents the development a facile but efficient method synthesis VO (M) nanoparticles by ball milling under ambient conditions, without release waste liquid or gases. The key variables related to synthesis, including time and molar ratio raw materials, have b...

Abstract In this study, we present the efficiency of remediation scenario to attenuate impact acid mine drainage (AMD) contamination in Kettara abandoned site. The study focuses on AMD groundwater Sarhlef shists aquifer. To predict evolution site under scenario, a model flow and transport was performed. Piezometric heads were measured at dry wet periods from eleven wells located downstream wast...
