Editorial The year 2009 has gotten off to a terrific start for SCMR on many fronts. The 2009 Annual Scientific Session was a resounding success based on the quality of the science and attendance. Overall attendance at all of the meetings including the pre-conferences (physician, basic science, and high field) and the technologist sessions was 1074, essentially unchanged from the prior year whic...

Diffuse pollution sources have been recognised by the European Water Framework Directive to significantly contribute to pollution of stormwater receivers. Stormwater runoff is considered to represent diffuse pollution sources. The aim of this study was to clarify the contributions of specific sources in the urban environment to the content of organic and inorganic pollutants in stormwater. This...

Asphalt shingles constitute more than 80% of the roofing materials in current residential housing United States. Many post-disaster surveys have reported failure these elements below design level wind event. Research to realistically model aerodynamics asphalt at full-scale is limited, resulting knowledge gaps peak loads and effects permeability. In this study, resistance are studied by using a...

Rooftops are both a source of and a pathway for contaminated runoff in urban environments. To investigate the importance of particle-associated contamination in rooftop runoff, particles washed from asphalt shingle and galvanized metal roofs at sites 12 and 102 m from a major expressway were analyzed for major and trace elements and PAHs. Concentrations and yields from rooftops were compared am...

Capture of odorant molecules by olfactory organs from the surrounding fluid is the first step of smelling. Sniffing intermittently moves fluid across sensory surfaces, increasing delivery rates of molecules to chemosensory receptors and providing discrete odour samples. Aquatic malacostracan crustaceans sniff by flicking olfactory antennules bearing arrays of chemosensory hairs (aesthetascs), c...

The halcyon days of Marcus Welby, when a doctor could simply “hang up a shingle” and be assured of a good living, are long passed. Physicians today must advertise, use lean management business practices, and, most importantly, code and bill effectively to have a financially healthy practice. This is particularly true for primary care physicians due to narrow margins and reliance on outpatient v...

Since the first investigations on web graph compression, it has been clear that the ordering of the nodes of the graph has a fundamental influence on the compression rate (usually expressed as the number of bits per link). The authors of the LINK database [2], for instance, investigated three different approaches: an extrinsic ordering (URL ordering) and two intrinsic orderings based on the row...
