the effect of geometry and material of the micro/nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. hertz contact model simulation for eph biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. then, to validat...
Introduction & Objective: Industrial wastewaters including heavy metals, are one of the important sources of environmental pollution. Heavy metals such as chromium is found in plating wastewater and is harmful for human health and environment. The purpose of the present study was to investigate adsorption of hexavalent chromium Cr (VI) from aqueous solution onto commerical Iron powder as an e...
introduction: arsenic is known as a carcinogenic compound in drinking water . it can cause acute and chronic effects on human health. in this study, the effect of polyamidoamine dendrimer generation 3(pamam g3) as adsorbents for removal of arsenic (v) from aqueous solutions was evaluated. methods: adsorption experiment was studied in batch system and the effect of different variables like p...
Modern computerized planning tools for periacetabular osteotomy (PAO) use either morphology-based or biomechanics-based methods. The latter relies on estimation of peak contact pressures and contact areas using either patient specific or constant thickness cartilage models. We performed a finite element analysis investigating the optimal reorientation of the acetabulum in PAO surgery based on s...
