Micropolar plasticity provides the capability to carry out post-failure simulations of geo-structures due to microstructural considerations and embedded length scale in its formulation. An essential part of the numerical implementation of a micropolar plasticity model is the integration of the rate constitutive equations. Efficiency and robustness of the implementation hinge on the type of int...

This talk will introduce the idea that talent development is related to learning where learning is the physiological process of neuro-plastic changes in the brain. To develop talents, individuals must move from novice or beginner’s status to expertise levels of knowledge or skills in a particular domain. Learning depends on maximizing an individual’s potential through the experience...

Synaptic plasticity in the central nervous system (CNS) of mammals has been discussed for many years. Several forms of synaptic plasticity of mammal’s CNS have been identified, such as those that occur in long-term potentiation (LTP). Different types of LTP have been observed in distinctive areas of the CNS of mammals. The hippocampus is one of the most important areas in the CNS that pla...

foundations behavior is affected by soil behavior which can vary from dilative to contractive depending on the stress level, particularly in dense frictional soils. the zero extension lines (zel) method has been generally developed to predict the foundations behavior. knowledge of soil behavior enables the zel method to predict the general and local shear failure modes. in this paper, a relativ...

in shallow foundations, the third bearing capacity factor, n, has been found to show a decreasing tendency with increasing the foundation size. it is supported by experimental observations and related mainly to stress level dependent nature of the soil. on the other hand, the bearing capacity is often obtained theoretically without consideration of the foundation vertical displacements. in thi...

the global environmental concerns have put the light weighting of structures on the fore front of the research in transportation industry. among other light weight alloys, the transportation industry is considering magnesium intensive light body-in-white structure in automotive applications. although the research in modeling technique areas is very active, a suitable practical model mimicking t...

introduction: endurance training has significant effects on the renewal of heart tissue, including myosin heavy chain (mhc) proteins. on the other side, purine-rich element-binding protein β (purb) decreases the &alphamhc; gene expression. the aim of this study was to determine the impact of exercise endurance training on purb gene expression in the heart of wistar rats. methods: fourteen rats ...
