Fear is a very strong stressor, and the highly variable results of handling and transportation studies are likely to be due to different levels of psychological stress. Psychological stress is fear stress. Some examples are restraint, contact with people, or exposure to novelty. In many different animals, stimulation of the amygdala with an implanted electrode triggers a complex pattern of beha...

During the last three decades, the introduction of new construction materials (e.g. RCC (Roller Compacted Concrete), strengthened gabions) has increased the interest for stepped channels and spillways. However stepped chute hydraulics is not simple, because of different flow regimes and importantly because of very-strong interactions between entrained air and turbulence. In this study, new air-...

Stilling basins are designed to reduce the high kinetic energy of supercritical flow in a downstream spillway. The USBR II stilling basin is distinguished by chute blocks fixed at upstream end and dented sill end, allowing for effective dissipation excess energy. This research investigates effect chute-block geometry on hydraulic performance basin. Six modified chute-blocks with identical dimen...

For overflow weirs and embankments, the stepped chute profile may increase the rate of energy dissipation on the waterway. Herein four different stepped chute configurations were tested with a focus on the cavity flow processes, flow aeration and energy dissipation performances. Detailed flow visualisations and air-water flow measurements were conducted for all configurations. The results highl...

Submitted for the MAR09 Meeting of The American Physical Society Constitutive relations in dense granular flows JOHN DROZD, COLIN DENNISTON, University of Western Ontario — We use simulations to investigate constitutive relations in dry granular flow. Our system is comprised of monoand poly-disperse sets of spherical grains falling down a vertical chute under the influence of gravity. We observ...
