we study the free oscillations of a non-rotating earth-like planet in the presence of a force free magnetic field. The model consists of a solid inner core, a liquid outer core and a solid mantle which is spherically symmetric. The lagrangian displacements are decomposed into scaloidal, poloidal and toroidal components using a gauged version of Helmholtz theorem. These components are identifi...
متن کاملEffects of T208E activating mutation on MARK2 protein structure and dynamics: Modeling and simulation
Microtubule Affinity-Regulating Kinase 2 (MARK2) protein has a substantial role in regulation of vital cellular processes like induction of polarity, regulation of cell junctions, cytoskeleton structure and cell differentiation. The abnormal function of this protein has been associated with a number of pathological conditions like Alzheimer disease, autism, several carcinomas and development of...
متن کاملBreak fill-dam simulation using GeoStudio (case study: Safarood earth dam, Kerman)
One of the main reason of earth-dam breaks is inner erosion which is caused by washing fine soil particles and finally lead to seepage inside the dam. Seepage will decrease effective tension in the earth-dam's core and arching phenomena is occurred. More settlement of core than to shell is the consequence of arching and occurrence of cracking. In this paper, GeoStudio software based on finite e...
متن کاملA Comparative Study on the Seismic Displacements of the Karkhe Large Embankment Dam with Mixed and Pure Clay Core-Iran
The water supply is the crucial problem of human beings in the world. Earth dams are usually the most important structures to store and manage the main sources: surface waters. The safety of earth dams in different conditions especially under earthquake loadings plays a vital role in sustainable developments. Recently, mixed-clay soil is widely used as water- seal material in the core of earth ...
متن کاملA Study on The Effect of Temperature on Human Prion Protein Structure through Molecular Dynamic Simulation
Background & Aims: The normal form of the prion protein is called PrPC and its infectious form is called PrPSc. This protein functions like a crystallized core for the transformation of PrPc into an abnormal PrPSc. The aim of the present study was to investigate the effect of temperature on human prion protein structure through molecular dynamic simulation. Methods: In this research, the GROMAC...
