1. The particulate form of lactating bovine mammary lactose synthetase activity is shown to be more highly organized than previously reported. 2. A novel method of shattering frozen mammary tissue with effective cell disruption is described. 3. The apparent subcellular distribution of lactose synthetase was shown to reflect the method of homogenization. 4. After mild homogenization particles as...

We consider the large-scale regularity of solutions to second-order linear elliptic equations with random coefficient fields. In contrast to previous works on regularity theory for random elliptic operators, our interest is in the regularity at the boundary: We consider problems posed on the halfspace with homogeneous Dirichlet boundary conditions and derive an associated C1,α-type large-scale ...

A specific issue in transformer modeling using the finite element method is the consideration of electric sheets or other laminated core materials which are commonly used to reduce eddy currents. Instead of explicitly modeling the geometry of every single core sheet material homogenization procedures can be applied. They substitute the laminated core structure for a virtual bulk material which ...

The term homogenization refers to a collection of methods for the description of the relations between the equations of \microstructure" and those of \macrostructure". It is a diverse eld since there is usually more than one way to formulate the problem. We refer to 3] , 8] and references therein for examples of various formulations and solutions of problems of homogenization. Ordinarily, one c...

BACKGROUND An accurate diagnosis of helminth infection is important to improve patient management. However, there is considerable intra- and inter-specimen variation of helminth egg counts in human feces. Homogenization of stool samples has been suggested to improve diagnostic accuracy, but there are no detailed investigations. Rapid disintegration of hookworm eggs constitutes another problem i...

The objective of this work was to study the physical properties of O/W emulsions stabilized by whey proteins. Coarse emulsions were prepared with 30% (w/w) soy oil and water phase containing 7% w/w of non heated and denatured whey proteins at 70 or 90oC. These emulsions were high pressure homogenized at 250, 450 and 600 bar in order to obtain fine emulsions. Creaming kinetics of the emulsions o...

We compared and statistically evaluated the effectiveness of nine DNA extraction procedures by using frozen and dried samples of two silt loam soils and a silt loam wetland sediment with different organic matter contents. The effects of different chemical extractants (sodium dodecyl sulfate [SDS], chloroform, phenol, Chelex 100, and guanadinium isothiocyanate), different physical disruption met...

Intensification of swine production in the U.S. and around the world requires advanced manure management. For swine manure management in the state of North Carolina, one system met all of the required advanced management criteria, and it was qualified as an environmentally superior technology. This investigation was part of the testing for this superior technology. The objectives of this invest...

In this talk we will present recent developments in the design and analysis of numerical homogenization methods. Numerical methods for linear and nonlinear partial differential equations that combine multiscale methods with reduced order modeling techniques such as the reduced basis method will be discussed. The talk is based upon a series of joint works with various collaborators[1,2,3,4,5]. [...

This paper deals with mean-field Eshelby-based homogenization techniques for multi-phase composites and focuses on three subjects which in our opinion deserved more attention than they did in the existing literature. Firstly, for two-phase composites, that is when in a given representative volume element all the inclusions have the same material properties, aspect ratio and orientation, an inte...
