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 ...

Development of brain function is instructed by both genetically-determined processes (nature) and environmental stimuli (nurture). The relative importance of nature and nurture is a major question in developmental neurobiology. In this dissertation, I investigated the role of visual experience in the development and plasticity of the visual pathway. Each neuron that receives visual input respon...

Correlations between compression index and atterberg limits found in the literature are very important for preliminary estimation. These equations usually interpreted based on R-square parameter classified according to conditions of data (disturbed, undisturbed, remoulded, etc.). Although correlations reliable enough eliminate oedometer tests not yet fully available, these can be useful local c...

you may have heard that the Brain is plastic. As you know the brain is not made of plastic, Brain Plasticity also called Neuroplasticity. Brain plasticity is a physical process. Gray matter can actually shrink or thicken neural connections can be forged and refined or weakened and severed. Brain Plasticity refers to the brain’s ability to change throughout life. The brain has the amazing abilit...

In this paper the studies of the two-phase super Plasticity stainless steels is studied. The aim of this study obtained the suitable criteria to thermo-mechanical treatment condition for decrease the microstructure (grain size) and super plasticity property in two-phase stainless steels. Also here we want to show the appropriate ranges of temperature and strain rate used in the process super pl...

shear modulus and damping ratio are important input parameters in dynamic analysis. a series of resonant column tests was carried out on pure clays and sand-clay mixtures prepared at different densities to investigate the effects of aggregate content, confining stress, void ratio and clay plasticity on the maximum shear modulus and minimum damping ratio. test results revealed an increase in the...

Introduction: Chronic morphine exposure can cause addiction and affect synaptic plasticity, but the underlying neural mechanisms of this phenomenon remain unknown. Herein we used electrophysiologic approaches in hippocampal CA1 area to examine the effect of chronic morphine administration on short-term plasticity. Methods: Experiments were carried out on hippocampal slices taken from either con...
