Electrospinning as a simple method was used to produce cellulose acetate porous fibers.Motivation for production of fibers with small diameter in the submicron and nano scales was to achieve the material with a large surfacearea with porosity formation in the structure of electrospun fibers.In this study, porous cellulose acetate (CA) fibers were p

Cellular and animal experiments and computational fluid dynamics (CFD) have revealed that mechanisms of the initiation, growth and rupture of a cerebral aneurysm are related to hemodynamics.By direct observation of a cerebral aneurysm during craniotomy, thinning or thickening sites can be found on the aneurysmal wall.The thinning site of a cerebral

A force balanced generalized molecular fractionation with conjugate caps (FB-GMFCC) method is proposed for ab initio molecular dynamic simulation of proteins.In this approach, the energy of the protein is computed by a linear combination of the QM energies of individual residues and molecular fragments that account ABSOLUT REPAIR SHAMPOO for the tw

We present a new bidimensional, spatially-explicit ecological model describing the dynamics of halophytic vegetation in tidal saline wetlands.Existing vegetation models employ relatively simple deterministic or stochastic mechanisms, and are driven by local environmental conditions.In the proposed model, in contrast, vegetation dynamics depend not
