A method for prediction of fine particle transport in a turbulent flow is proposed, the interaction between particles and fluid is studied numerically, and fractal agglomerate of fine particles is analyzed using Taylor-expansion moment method. The paper provides a better understanding of fine particle dynamics in the evolved flows.

BACKGROUND Split- thickness skin graft is one of the most common operations in plastic surgery. It is always painful and patient discomfort from donor site often is more significant than recipient site. There is not still a standard method for treatment of the donor site. The purpose of this study was to determine the best method of dressing the donor site among three different methods with re...

mucormycosis is a fatal and life threatening infection particularly in immunocompromised patients, so early diagnosis and rapid treatment is life saving. a 52-year-old female, known case of diabetes mellitus, presented with chills, fever, fatigue and anorexia. a subcutaneous mass was detected around the umbilicus (4x4). fine needle aspiration of the mass showed mucor hyphea with little inflamma...

cobalt ferrite nano-powder have been obtained through a hydrothermal method with 2:1 molar ratio of fe:co without using any surfactant. x-ray diffraction (xrd) and scanning electron microscopy (sem) were used to consider the structural and morphological properties of cofe2o4 nano-particles. also, edax spectroscopy applied to evaluate the chemical composition. results demonstrated that 15 hr hyd...

Among different types of controlling systems, the ON/OFF digital relative humidity control was used for measuring electrical properties of cashmere fibers to make the ambient relative humidity fixed. To achieve this goal the required hardware and software were designed and fabricated. The electrical resistance of fine and coarse hair cashmere fiber was measured by charge and discharge condenser...

This paper presents a stabilized mixed finite element method for the first-order form of advection–diffusion equation. The new method is based on an additive split of the flux-field into coarseand fine-scale components that systematically lead to coarse and fine-scale variational formulations. Solution of the fine-scale variational problem is mathematically embedded in the coarse-scale problem ...

We present the variational multiscale (VMS) method for partial differential equations (PDEs) with stochastic coefficients and source terms. We use it as a method for generating accurate coarse-scale solutions while accounting for the effect of the unresolved fine scales through a model term that contains a fine-scale stochastic Green’s function. For a natural choice of an “optimal” coarse-scale...

The practical use of recycled concrete aggregate produced by crushing concrete waste reduces the consumption of natural aggregate and the amount of concrete waste that ends up in landfills. This study investigated two methods used in the production of fine recycled concrete aggregate: (1) a method that produces fine as well as coarse aggregate, and (2) a method that produces only fine aggregate...
