Introduction Application of a Hierarchical Habitat Unit Classification System: Stream Habitat and Salmonid Distribution in Ward Creek, Southeast Alaska M.D. Bryant, B.E. Wright, and B.J. Davies A hierarchical classification system separating stream habitat into habitat units defined by stream morphology and hydrology was used in a pre-enhancement stream survey. The system separates habitat unit...

Aortic aneurysms are classified as complex based on their extent and involvement of side branches. Complex aortic aneurysms include arch, thoracoabdominal, juxtarenal and suprarenal aortic aneurysms. Open surgical repair carries high morbidity and mortality beyond large tertiary care centers. During the last decade, numerous technological advances have allowed incorporation of side branches usi...

The microbial electrochemical snorkel (MES) is a low-cost, low-maintenance technology that could considerably reduce wastewater treatment costs by reducing the need for aeration. An MES single electrode. lower part, in anoxic zone of bioreactor, oxidizes organic matter transferring electrons to upper oxic zone, releases dissolved oxygen. This study gives new insights into correlation between po...

light is never being distributed homogeneously and it forms a gradient over biomass. the unidirectional nature of light gives rise to a vertical gradient of light intensity as a function of depth. the maximum depth of the light zone suitable for phytoplankton photosynthesis is designated as the euphotic depth. this study was designed to test the hypothesis of mixing depth of phytoplankton and i...

An individual case review of the diving-related deaths that were reported to have occurred in Australia in 2003 was conducted as part of the combined Project Stickybeak/DAN Asia-Pacific dive fatality reporting project. The case studies were compiled using reports from witnesses, the police and coroners. In each case, the particular circumstances of the accident are provided, as well as details ...
