We study the roughening transition of a (3+1)-dimensional elastic manifold, which is driven by the competition between a periodic pinning potential and a random impurity potential. The elastic manifold is modeled by a solid-on-solid-type interface model, and the universal properties of the transition from a flat phase (for strong periodic potential) to a rough phase (for strong random potential...
This chapter examines the effects of femoral neck geometry and topological structure on elastic properties. A finite element code is used to calculate the full elastic tensor for thirteen human proximal femur specimens. We show that the micro-structure within the human femoral neck and head gives rise to approximate orthotropic elastic symmetry at the whole bone scale. The finite element code c...
background & aim:nepeta racemosa is an herbal and medicinal plant and this report aims to identify chemical compositions of the essential oils and volatiles of its aerial parts through classical and advanced methods. experimental: chemical profiles of the essential oils and volatile compounds from the aerial parts of nepeta racemosa obtained through hydrodistillation (hd), solvent-free mic...
This paper considers the problem of stiction in electrostatic-elastic deflections whereby elastic surfaces adhere to one another after coming into physical contact under attracting Coulomb interactions. This phenomenon is studied in a family of recently derived models which account for forces which become important when the elastic surfaces are in close proximity. The presence of bistability in...
