An experiment was carried out to determine the effect of corn silage particle size and fat supplements on performance, solid passage rate through the digestive tract, and chewing behavior in dairy cows. The forages were coarse or fine corn silage with geometric means of 8.8±2.7 and 5.6±2.8 mm, and alfalfa with geometrics means of 7.0±3.3 mm, and fat supplements were neutral fat (palm) and soy-o...

Political principals typically use low-cost ‘‘fire-alarm’’ signals transmitted by the media, interest groups, and disaffected constituents to monitor the activities of regulatory agencies. We argue that regulatory decision making is biased and inconsistent if the instruments of political oversight are simple and the information flows to the principal are coarse relative to the complexity of the...

We are developing human activity simulations that could be used to test distributed video sensor networks. Our ultimate goals are to build statistical models of pedestrian density and flows at a number of urban locations and to correlate those flows with population movement and density models represented in a spatiotemporal modeling system. In order to create known populace flows, we have built...

The main purpose of this paper is to establish a relation between universality of certain P-compactifications of a semitopological semigroup and their corresponding enveloping semigroups. In particular, we show that if we take P to be the property that the enveloping semigroup of a compactification of a semitopological semigroup s is left simple, a group, or the trivial singleton semigroup, t...

An ultrafine grain surface layer with average crystallite size of 28 nm was produced on annealed mild steel through a wire brushing process. The effects of grain size reduction on the inhibition performance of sodium phosphate were investigated using polarization and electrochemical impedance spectroscopy (EIS) measurements. The crystal grain size of wire brushed surface was analyzed by X-ray d...

Griffiths, R.W. and Linden, P.F., 1981. The stabil i ty of buoyancy-dr iven coastal currents. Dyn. Atmos . Oceans, 5: 281--306. Buoyancy-dr iven boundary currents were generated in the labora tory by releasing buoyan t fluid f rom a source adjacent to a vertical boundary in a rota t ing container . The boundary removed the Coriolis force parallel to it, a l lowing the buoyan t fluid to spread i...

This paper presents the results of simulations particle-laden air–solid jet flow in long straight tubes using CFD-DEM, along with an analysis coarse-graining. Although previous studies have used CFD-DEM for similar flows, these typically been a dilute regime where uncoupled can be effectively. However, fully coupled introduce issues, necessitating validation to ensure that all coupling paramete...
