Maxwell Stress Tensor (MST) method is investigated in this study to quantify the degree of approximation made with the point–dipole method in respect to dielectrophoresis (DEP) in micro–devices. Latex particles and biological cells immersed in aqueous buffers of various conductivities are considered. The two methods (point–dipole and MST full approaches) are compared using analytical dipolar so...

Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 49: 1.1 1.9. A deterministic finite element solution to predict water flow and nutrient movement through porous media was developed and implemented using Visu...

Nutrient absorption in the small intestine cannot occur until molecules are presented to the epithelial cells that line intestinal villi, finger-like protrusions under enteric control. Using a two-dimensional multiscale lattice Boltzmann model of a lid-driven cavity flow with 'villi' at the lower surface, we analyse the hypothesis that muscle-induced oscillatory motions of the villi generate a ...

BACKGROUND Patients with long-term complications of sulfur mustard (SM) poisoning are often less able to undertake optimum levels of physical activity and adequately control their dietary intake. The aim of present study was to investigate the dietary intake of patients with SM poisoning in comparison to a control group Methods: The study was undertaken on 55 Iranian male veterans, who had > 25...

Micro nutrients deficiency is a major problem in women of reproductive age and one of the most important micro nutrient deficiencies in many developing countries is Zinc deficiency. It is estimated that 82% of all pregnant women in the world have Zinc deficiency. Zinc is an important micro nutrient in fetal growth and development. The role of Zinc in pregnancy outcomes has been studied in past ...

PURPOSE To establish a three-dimensional finite element model for orthodontic anchorage micro-implant,and to analyze the influence of different titled angles on the biomechanical characteristics of orthodontic anchorage implant-bone interface. METHODS ANSYS(Analysis System)finite element analysis software was used to perform the finite element modeling of the micro-implant with 7 different ti...

Among factors affecting hydroponic production systems, the nutrient solution is considered to be one of the most important determining factors of crop yield and quality. This chapter aims to explain aspects related to plant nutrition and its effects on production of hydroponic crops, considering basic aspects such as nutrient solutions and their development through the years; components of nutr...

A finite element heterogeneous multiscale method is proposed for solving the Stokes problem in porous media. The method is based on the coupling of an effective Darcy equation on a macroscopic mesh, with unknown permeabilities recovered from micro finite element calculations for Stokes problems on sampling domains centered at quadrature points in each macro element. The numerical method account...
