During the plastic state of concrete, any hindrance or resistance free volume change in concrete induce tensile stresses and strains element. Crack formation is expected to occur if stress strain greater than capacity concrete. Investigation into properties relaxation behaviour was carried out using a direct testing machine. The capillary pressure measured during tests low evaporation condition...

In this study we estimate the subcutaneous tissue counter pressure during drug infusion from a series of injections of insulin in type 2 diabetic patients using a non-invasive method. We construct a model for the pressure evolution in subcutaneous tissue based on mass continuity and the flow laws of a porous medium. For equivalent injection forces we measure the change in the infusion rate betw...

Under upper crustal conditions, deformations are primarily brittle (i.e., localized) and accommodated by frictional mechanisms. At greater depth, ductile distributed) crystal plasticity, diffusion mass transfer or cataclastic flow. The transition from the to domain is not associated with a critical but rather varies in time space. One main parameter controlling variation of this pore fluid pres...

background when a primary radiation interacts with a medium, the secondary radiations are produced, that the contribution of these secondary radiation should considered in the calculation of dose. build-up factor is a dosimetric correction factor to assume effect of secondary radiation in calculation of dose. calculation of this factor is very difficult and time consuming. due to significance o...
