Synthesis of novel ambifunctional atropisomeric 2,2',6,6'-tetrasubstituted biphenyls and investigation of their properties and organocatalytic activity

Creator:: Sephton, Mark Alan
Abstract:: Ambifunctional axially chiral 2,2',6,6'-tetrasubstituted biphenyls containing nucleophilic (or basic) functional groups juxtaposed with hydrogen-bond donors were synthesized and their properties studied. Applications for the prepared biaryls as potential organocatalysts for enantioselective carbon-carbon bond forming reactions were examined. Processes investigated included: aldol, Michael, nitroaldol (Henry), and Baylis-Hillman reactions. The novel amidoamine...

Mi Corazon Dice No, ¿el tuyo? The Anti-Central American Free Trade Agreement Social Movement in San José, Costa Rica

Creator:: Pride, Samantha and Pride, Samantha F.
Abstract:: The Central American Free Trade Agreement (CAFTA) is between the United States and Costa Rica, Nicaragua, Honduras, Guatemala, El Salvador and the Dominican Republic. CAFTA was decided in Costa Rica by a national referendum in 2007, after years of delay that left Costa Rica as the only country to have...

Institutional capacity building through land and water stewardship integration - an analysis of source water protection in Corvallis, Oregon

Creator:: Odom, Olivia
Abstract:: Globally, access to safe, reliable drinking water sources is a major challenge of this generation. Protected sources of drinking water provide communities with a sustainable, vital resource, yet many public water suppliers lack legal authority over their source water protection (SWP) area, especially in surface water systems. Absence of legal...

Basic and applied studies on Douglas-fir beetle : spatial relationships of infestations, lipids and host habitat, and attraction distances of pheromone-baited traps

Creator:: Dodds, Kevin J.
Abstract:: Three studies on Douglas-fir beetle (DFB), Dendroctonuspseudotsuae, were conducted to investigate its basic and applied biology. Studies included investigations into the spatial relationship of DFB infestations over multiple years and multiple landscapes, relationships between DFB brood adult lipid levels and position of development along the length of tree boles, and...

Larval dispersal in marine fishes: novel methods reveal patterns of self-recruitment and population connectivity

Creator:: Christie, Mark R.
Abstract:: Many marine fish populations are severely declining due to over-fishing, loss of both juvenile and adult habitats, and accelerating environmental degradation. Fisheries management and the implementation of marine protected areas (MPAs) and other conservation tools are currently hindered by large gaps in knowledge about larval dispersal and its subsequent effects...

Indirect effects of fishing on predators and their prey

Creator:: Stallings, Christopher Derek
Abstract:: Predators are fundamentally important for regulating and driving prey population dynamics as well as structuring ecological communities. Over-exploitation of marine resources has caused dramatic depletions of predatory fish species and shifts in marine community composition, with attendant declines in productivity and diversity of marine ecosystems. Despite the important ramifications of...

An alternative architecture for performing basic computer arithmetical operations

Creator:: Djang, Kevin
Abstract:: The arithmetic portions of almost all modern processor architectures are of very similar design. We use the term "traditional" to describe this design, the primary characteristics of which are native support for integer and floating-point number types and special disjoint instructions and hardware for each supported type. Decades of refinement...

Investigation of new compatibilizer systems for wood-polyethylene composites

Creator:: Geng, Yu
Abstract:: Wood-plastic composites (WPCs) are one of the fastest-growing sectors of the wood composites industry. However, the strengths of WPCs are typically low because of the poor interfacial adhesion between hydrophilic wood and hydrophobic thermoplastics. A compatibilizer that can form bridges between wood and plastics is required to give WPCs desirable...

Atropisomeric 8,8'-biquinolyl derivatives : synthesis, properties and applications

Creator:: Milicevic, Selena D.
Abstract:: 7,7'-Dihydroxy-8,8'-biquinolyl (azaBINOL) was prepared from 7-hydroxyquinoline via N,N-dimethyl O-quinol-7-yl carbamate by directed ortho-metallation followed by FeCl₃-mediated oxidative coupling of the 8-lithioquinoline intermediate. Saponification of the resulting dicarbamate provided crystalline (±)-azaBINOL in 56% overall yield. 6,6'-Bis(dimethylaminocarbonyl)-7,7'-dihydroxy-8,8´-biquinolyl was prepared from the same dicarbamate by a double anionic-Fries rearrangement in 43% yield. 7,7'-Bis(diethylamino-carbonyloxy)-6,6'-diiodo-8,8´-biquinolyl...

Establishment and growth of natural and planted conifers ten years after overstory thinning and vegetation control in 50-year-old Douglas-fir stands

Creator:: Nabel, Mark R.
Abstract:: Forest managers of public lands in western Oregon and Washington have become increasingly interested in creating additional conifer cohorts in young, even-aged, second-growth Douglas-fir stands. The purpose of our research was to assess the establishment, survival, and growth of naturally-regenerated and underplanted conifers 10-13 years after overstory thinning and understory...
