McCauley, E., Lewis, Mark A., Lutscher, F.
The question how aquatic populations persist in rivers when individuals are constantly lost due to downstream drift has been termed the “drift paradox.” Recent modeling approaches have revealed diffusion-mediated persistence as a solution. We study logistically growing populations with and...

Effects of phytase supplementation on performance and phosphorus excretion from broiler chickens fed low phosphorus-containing diets based on normal or low-phytic acid barley
Download2009-01-01
Thacker, Philip A., Haq, Inam, Willing, Benjamin P., Leytem, April B.
A total of 240 day-old broiler chicks were used to study the effects of phytase on performance and phosphorus (P) excretion from birds fed diets containing low phytate barleys formulated without inorganic P. A positive control based on Harrington barley (HB) was formulated to meet requirements...

Meat tenderness may be improved by accelerating muscle metabolism or by damaging muscle structure and increasing the solubility of muscle proteins. Pre- and postrigor protein and collagen solubilities were measured in semitendinosus muscles, removed pre-rigor from 24 Charolais crossbred steer...

Effects of prepartal oronasal administration of lipopolysaccharide on milk composition and productivity of transition Holstein cows
Download2013
Ametaj, Burim N., Dunn, Suzanna M., Zebeli, Qendrim, Iqbal, Summera, Mansmann, Dominik A.
The aim of this study was to evaluate the effects of repeated oronasal administration of lipopolysaccharide (LPS) on milk composition and the overall productive performance of dairy cows. One hundred pregnant Holstein dairy cows were randomly assigned to two treatment groups (n = 50). 30 cows out...

Effects of production system and growth promotants on the physiological maturity scores in steers
Download2014
Aalhus, J. L., Basarab, J. A., N. Prieto, I. L., López-Campos, Ó., Larsen, M.
Over a 2-yr period, 224 crossbred steers were allotted to a 2×2×2 factorial arrangement of treatments to determine the effect of the production system (calf-fed vs. yearling-fed), growth implant strategy (non-implanted vs. implanted) and β-agonist supplementation (no ractopamine vs. ractopamine)...

Effects of recreational traffic on alpine plant communities in the northern Canadian Rockies
Download2012
MacDonald, S. E., Crisfield, V., Gould, J.
Abstract: Recreational activities in alpine areas have been increasing in recent decades, creating the need to improve our understanding of the impacts of these activities and how they are best managed. We explored impacts of recreational trail use on dry alpine meadows in the northern Canadian...

EFFECTS OF SCANDIUM ON HYPO-EUTECTIC ALUMINUM COPPER MICROSTRUCTURES UNDER LOW SOLIDIFICATION RATE CONDITIONS
Download2017-11-01
Bogno, A.-A., Valloton, J., Henein, H., Ivey, D.G., Locock, A.J., Gallerneault, M.
This work addresses the microstructures and mechanical properties of Al-4.5 wt% Cu alloys containing 0.1, 0.2 and 0.4 wt% Sc that were solidified under low cooling rate conditions (< 1ºC/s) and then heat treated. The samples were solidified in a differential scanning calorimeter before being heat...

Bogno, A.-A., Henein, H., Ivey, D.G., Valloton, J., Reinhart, G., Sediako, D., Gallerneault, M.
This paper reports on the characterization of rapidly solidified Al-4.5 wt% Cu-xSc (x= 0.1, 0.2 or 0.4 wt %). The effect of micro-additions of Sc (up to 0.4 wt %) was examined through microstructural analysis of rapidly solidified, as well as aged samples, by means of electron microscopy, x-ray...

Effects of seismic lines on the abundance of breeding birds in the Kendall Island Bird Sanctuary, Northwest Territories, Canada
Download2008
Ashenhurst, A.R., Hannon, S.J.
Current plans to increase oil and gas exploration and extraction in the Canadian Arctic include development in the Kendall Island Bird Sanctuary, Northwest Territories. Various studies have shown impacts of seismic lines on vegetation, but the effects on bird abundance in the Arctic are poorly...
