A ruthenium-carbamato-complex derived from a siloxylated amine and carbon dioxide for the oxidative a-cyanation of aromatic and cyclic tertiary amines
Download2013-10-09
The ruthenium carbamate complex derived from 3-trimethoxysilyl-1- propyl amine and carbon dioxide was found to be a novel catalyst for the oxidative cyanation of aromatic and cyclic tertiary amines to corresponding a-amino nitriles in high to excellent yields by using hydrogen peroxide and...

Achieving Conservation when Opportunity Costs Are High: Optimizing Reserve Design in Alberta’s Oil Sands Region
Download2011-08-17
Using Alberta, Canada, as a case study we use a trade-off analysis to systematically explore the relationship between conservation targets and economic opportunity costs in the context of coarse-filter reserve design. We use the Marxan conservation planning software to generate reserve designs at...

Characterizing the performance of ecosystem models across time scales: A spectral analysis of the North American Carbon Program site-level synthesis

Black, T.A., Izaurralde, R.C., Lokupitiya, E., Munger, J.W., Schaefer, K., Weng, E., Richardson, A.D., Altaf Arain, M., Luo, Y., Ciais, P., Ricciuto, D.M., Stoy, P.C., Dietze, M.C., Poulter, B., Barr, A.G., Liu, S., Hollinger, D., Tian, H., Suyker, A.E., Verbeeck, H., Price, D.T., Grant, R.F., Peng, C., Baker, I.T., Vargas, R., Anderson, R.S., Tonitto, C., Sahoo, A.K., Chen, J.M., Flanagan, L.B., Riley, W.J., Wang, W., Lafleur, P., Gough, C.M., Verma, S.B., Kucharik, C.J.
Ecosystem models are important tools for diagnosing the carbon cycle and projecting its behavior across space and time. Despite the fact that ecosystems respond to drivers at multiple time scales, most assessments of model performance do not discriminate different time scales. Spectral methods,...

Gardner Costa, J.M., Daly, c., Kovalenko, K.E., Dixon, D.G., Ciborowski, J.J.H., Slama, C.A., Kennedy, K., Foote, A.L., Liber, K., Smits, J.E.G., Frederick, K.R., Roy, M.C., Farwell, A.J.
Boreal wetlands play an important role in global carbon balance. However, their ecosystem function is threatened by direct anthropogenic disturbance and climate change. Oil sands surface mining in the boreal regions of Western Canada denudes tracts of land of organic materials, leaves large areas...

For much of the history of Alberta’s tar sands, a series of visual conventions have shaped Canadian imaginaries of the resource, the emergence of the non-conventional oil industry, and the mining of oil. We introduce a series of archival images dating from 1880 until the opening of Great Canadian...

Abstract: Fine tails, the resulting fine waste from oil sand processing, undergoes large-strain consolidation in tailings ponds. Its consolidation behavior must be analyzed using a large-strain consolidation theory, which requires the determination of the relationship between the void ratio and...

Martin-McDonald, K., Spiers, J., Weaver, K.
The experiences of women with eating disorders and the meanings drawn from these experiences are largely hidden from health care professionals and thus are poorly represented in clinical and academic discourse. This study examined interpersonal relationships in the context of anorexia nervosa...

Progressive failure analysis of windrow induced slope movements at the Syncrude Limited mine site
Download1997
Chan, D. H., Mathioudakis, M., Morgenstern, N. R.
The presence of Marine Sediments below the operating bench in the Syncrude Canada Limited oil sand mine (NE Alberta, Canada) has negatively affected dragline mining operation. Any material that exhibits strain softening behaviour is prone to progressive failure. The Marine Clays at the Syncrude...

Simple and Robust Algorithm for Multiphase Equilibrium Computations at Temperature and Volume Specifications
Download2021-05-25
Lu, Chang, Jin, Zhehui, Li, Huazhou, Xu, Lingfei
Two-phase and three-phase equilibria are frequently encountered in a variety of industrial processes, such as carbon dioxide (CO2) injection for enhanced oil recovery in oil reservoirs, multiphase separation in surface separators, and multiphase flow in wellbores and pipelines. Simulation and...
