Introduction Pressure ulcers are tissue damages resulting from blood flow restriction, which occurs when the tissue is exposed to high pressure for a long period of time. These painful sores are common in patients and elderly, who spend extended periods of time in bed or wheelchair. In this study, a continuous pressure and temperature monitoring system was developed for pressure ulcer preventio...

Thermo-Elasto-Plastic analyses of thick-walled spherical tanks made of functionally graded materials are investigated analytically. These tanks are subjected to positive or negative temperature gradient and internal pressure loadings separately or simultaneously. The power law modeling has been used for through-the-thickness variation of mechanical properties. von Mises yield criterion and Elas...

marine environment of the caspian sea, due to extensive human exploitation and discharge of large magnitudes of urban, industrial and agricultural waste, is under extensive pressure and human wastes threaten marine life and ecosystem of the sea. therefore, there is a substantial need for a good understanding of physical and chemical characteristics of the caspian waters. however, the data avail...

supersonic separators have found extensive applications in dehumidification of natural gases since 2003. unlike previous studies, which have investigated the inlet conditions and nozzle geometry of supersonic separators for pure fluids, the present study employed a combination of momentum, heat, and mass transfer equations along with virial equation of state (eos) to inspect the effect of inlet...

Introduction According to geographical location of Iran and relatively high elevation of most of its areas above sea-level, occurrence of frosts has many negative effects on different sections, such as agricultural, transportation and energy. Frosts are generally related to displacement and movement of cold anticyclones from northern latitudes to Iran. Wide range of synoptic characteristics is...
