Phenotypic plasticity is often considered important for invasive plant success, yet relatively few studies have assessed plasticity in both native and invasive populations of the same species. We examined the plastic response to temperature for Bromus tectorum populations collected from similar shrub-steppe environments in the Republics of Armenia and(More)
Practical experience has shown that parasitic effects such as rotor eccentricity can have crucial influence on the performance of switched reluctance machines. Strong eccentricity can even be a knock-out criterion as it potentially causes additional acoustic noise and increased bearing wear. Nowadays only very few publications consider simulation methods(More)
Roughage is typically mechanically processed to increase digestibility and improve handling and mixing characteristics in beef cattle finishing diets. Roughage is fed to promote ruminal health and decrease digestive upset, but inclusion in finishing diets is limited due to the cost per unit of energy. Rumination behavior may be a means to standardize(More)
Roughage is fed in finishing diets to promote ruminal health and decrease digestive upset, but the inclusion rate is limited because of the cost per unit of energy and feed management issues. Rumination behavior of cattle may be a means to standardize roughage in beef cattle finishing diets, and increasing the particle size of roughage could modulate the(More)
The cost-efficient switched reluctance machine is highly appealing to the automotive industry. In this application acoustic noise is a crucial criterion, which is usually addressed during the design process. However, parasitic effects, such as rotor eccentricity, are normally not a design target but only a finding during the test of the prototype. This(More)
Two experiments were conducted to evaluate the effects of feeding condensed distiller's solubles (DS) and crude glycerin alone or in combination on performance of finishing beef cattle and in vitro fermentation. In both experiments, dietary treatments consisted of a steam-flaked corn-based diet with 0% DS or crude glycerin (CON), 10% DS (CDS), 10% crude(More)
