The objective of this experiment was to evaluate effects of reducing corn silage particle size on eating behavior, chewing activity, and rumen fermentation in lactating dairy cows. Four cannulated, multiparous cows averaging 110 +/- 4 d in milk and weighing 675 +/- 70 kg were randomly assigned to a 4 x 4 Latin square. During each of four 14-d periods, animals were offered one of four diets that...

Mixed matrix membranes (MMMs) are attracting significant interest for pervaporation and gas separation applications. To better comprehend the impact of filler particles within polymer matrices, the species permeation mass transport was theoretically studied by numerical simulation using finite differences. The Fick’s second law of diffusion was solved for a three-dimensional MMM to obtain the c...

In the first part of this thesis the means are described by which an industrial disc stack centrifuge may be scaled-down to process in a meaningful fashion small volumes of particle suspensions. The centrifuge separation characteristics so measured were suitable for direct scale-up predictions of centrifuge performance. Experiments with a dye tracer and a reduced number of discs indicated that ...

We show that disorder-induced interaction between guided modes and a flat band of low-Q radiating modes in planar arrays of dielectric particles can lead to frequency-selective omni-directional scattering of light. This phenomenon is numerically observed in planar arrays consisting of periodically arranged dielectric particles with small randomness in particle sizes. The flat band of low-Q radi...

Feed ingredients used in poultry feed, generally require size reduction before being mixing rations, such as corn. The process of reducing the corn is initial that must be carried out for ration production. machine commonly to reduce hammer mill. This study aims determine particle and physical characteristics a feed ingredient by grinding using was arranged completely randomized design with fou...
