Technical report TR10-01. Compared to optimal planners, satisficing planners can solve much harder problems but may produce overly costly and long plans. Plan quality for satisficing planners has become increasingly important. The most recent planning competition IPC-2008 used the cost of the...

Active transport (i.e., moving oneself from place to place by walking, cycling, or other active means) is recognized as a sustainable and inclusive form of transportation. It is also a primary source of physical activity for most adults and the associated benefits are clear for community...

Vanadium concentrations of 2.4 to 5.6 mg/L were lethal in 7 days to rainbow trout of wet weight 1.2-6.2 g. The LC50 varied slightly over the 12 combinations of water quality, from hardness 30 to 350 units and pH 5.5 to 8.8. The 7-day LC5O may be estimated by the following equation, which...

The purpose of this study was to determine the acute and subacute toxicity of bitumen to rainbow trout. The bitumen was collected along the banks of the Athabasca River downstream of Fort McMurray during 1984. Prior to experimentation, the bitumen was fractionated in water at 35°C, using an...

Mine depressurization water obtained from five wells on Lease 17 held by Syncrude Canada Limited, was examined for chemical composition and acute toxicity to two species of fish. In the first series of experiments, mine depressurization water was diluted with various proportions of water...

Volume 2 In order to conduct oil sands mining operations in the surface mining region of the Athabasca oil sands deposits, most regions require depressurization of the basal sandstone formations. The groundwater produced by depressurization operations is of poor enough quality to be toxic to...

When evaluating this data, lethality (i.e. death of the organism) is the symptom being observed. Acutely lethal refers to a sample killing 50% of a population after 96 hours exposure. 1. The dike filter drainage was found to be acutely toxic to both rainbow trout and brook sticklebacks. The...
