The biological approaches to synthesis of nanoparticles are better than chemical and physical procedures because of low energy and time expenditure. This method requires no use of toxic solvents and synthesis of dangerous products and no environmental hazards. Green synthesis of nanoparticles that have environmentally acceptable solvent systems and(More)
Epidemiological studies have identified obesity asa possible risk factor for low back disorders. Biomechanical models can help test such hypothesis and shed light on the mechanism involved. A novel subject-specific musculoskeletal-modelling approach is introduced to estimate spinal loads during static activities in five healthy obese (BMI>30kg/m2) and five(More)
Lateral-torsional buckling is one of the modes of instability of steel beams that happened when steel beams are slender. Due to the widespread application of I-girder in bridges, this paper develops a three-dimensional finite-element model using ANSYS for the inelastic nonlinear flexural-torsional analysis of I-girder and uses it to investigate the effects(More)
The saturation distribution and clean up efficiency of light non-aqueous phase liquid (LNAPL) in the strata beneath the earth has been the subject of many studies. Better understanding of LNAPL infiltration into layered soil is important for the effective design of remediation strategies. The objective of this study was to simulate LNAPL movement in(More)
