Embryonic loss of potential lambs resulting in partial failure of multiple ovulations is a significant factor in the reproductive rate of prolific breeds. The roles of genetic and nutritional variation (and their possible interaction) on embryonic loss were studied by mating blackface and whiteface ewes of either high or low...
Recent studies of flow boiling within microchannels have shown high heat fluxes, leading to successful design and testing of compact heat exchangers, cooling systems for electronics and other high efficiency, miniature components. An experimental study of flow boiling of a concentrated salt solution in microchannels is presented. Experiments examined flow...
Understanding the drivers and implications of anthropogenic disturbance of ecological connectivity is a key concern for the conservation of biodiversity and 50 ecosystem processes. Here, we review human activities that affect the movements and dispersal of aquatic organisms, including damming of rivers, river regulation, habitat loss and alteration, human-assisted dispersal...

Bdellovibrio bacteriovorus 100 and B. stolpii UKi-2 each produce
two extracellular proteases which attack Azocoll (collagen)
while B. starrii A3.12 produces at least four such proteolytic
enzymes. Under standard growth and assay conditions each Bdellovibrio
species produces a unique amount of proteolytic activity. The
decreasing order of enzyme units was...
The growth of bdellovibrios at the expense of the host organism involves the catabolism of host cell macromolecular components and the subsequent anabolistic incorporation into bdellovibrio progeny. Extracellular enzymes specific for the various substrates provided by the host cell are present. In this study the extracellular RNase of Bdellovibrio bacteriovorus...
This study examines the spatial variability of ozone fluxes over flat heterogeneous terrain consisting of a patchwork of irrigated and nonirrigated surfaces. Fluxes of ozone and other quantities are computed from eight sequential flight legs of the Canadian Twin Otter research aircraft over the same track at 33 m above...
Off-pump Coronary Artery Bypass Graft (CABG) surgery outperforms traditional on-pump surgery because the assisted robotic tools can alleviate the relative motion between the beating heart and robotic tools. Therefore, it is possible for the surgeon to operate on the beating heart and thus lessens post surgery complications for the patients....
