Adult 4-H volunteer empowerment in 4-H youth development settings

Creator:: Olsen, Pamela
Abstract:: The primary purpose of this study was to determine which factors related to adult 4-H volunteer empowerment in 4-H youth development settings. This study examined the relationship of adult 4-H volunteers’ perceived leadership styles of Oregon 4-H Youth Development Educators (YDE) to the adult 4-H volunteer sense of empowerment. In...

Equilibria in the ion exchange systems H⁺¹-CS⁺¹, H⁺²-Sr⁺², H⁺¹-Ce⁺³, Cs⁺¹-Sr⁺², Sr⁺²-Ce⁺³, H⁺¹-Cs⁺¹-Sr⁺², H⁺¹-Cs⁺¹-Ce⁺³ and H⁺¹-Sr⁺²-Ce⁺³

Creator:: Meyer, Walter
Abstract:: A new method for determining ion exchange equilibrium data by liquid scintillation counting of the equilibrated solution phase is described. This method has been applied to determine equilibria between Dowex 50W X8, a commercial strong cation exchange resin, and binary and ternary solution containing the varying combinations of H⁺¹, Cs⁺¹,...

Studies on the biosynthesis of the streptolidine moiety of streptothricin F

Creator:: Wityak, John
Abstract:: The loss of all deuterium labels from previous feedings of [2-²H]-, [3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the biosynthesis of the streptolidine portion of streptothricin F (la). In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]- arginine (32) was...

Mass Spectrometry-based Analysis of Superwarfarins and their Metabolites and the Investigation of Novel Treatments for Poisoned Victims

Creator:: Nosal, Daniel Grzegorz
Abstract:: Superwarfarins are anticoagulant rodenticides that are 100 times more potent and 15 times more persistent than warfarin. They have been used since the 1980s and cause over 10,000 cases of accidental and intentional poisonings per year. Apart from inducing uncontrollable bleeding, by inhibiting the vitamin K cycle, superwarfarins can disrupt...

Comprehensive, Low-Cost Wicking Microfluidic Analytical Devices for Clinical Diagnostics and Environmental Analysis

Creator:: Bandara, Gayan C.
Abstract:: Analytical techniques are utilized in a wide variety of applications. Traditionally, analytical measurements are achieved by trained personnel in a laboratory setting using expensive scientific instruments, which limits their applicability in resource-limited areas and point-of-care applications. Therefore, the concept of enabling these laboratory-based qualitative and quantitative assays in microfluidic device...

Enhancement of cold tolerance in tomato plants by genetic engineering of glycinebetaine biosynthesis

Creator:: Park, Eung-Jun
Abstract:: Tomato [Lycopersicon esculentum Mill.] plants are chilling sensitive and do not naturally accumulate glycinebetaine (GB), a metabolite that functions as a stress protectant in plants. While GB can increase tolerance of tomato plants to salt and drought stresses, its effect on chilling tolerance has not been examined. To evaluate whether...

Ectopic overexpression of Arabidopsis CBF genes enhances freezing tolerance of two potato species

Creator:: Pino, María-Teresa
Abstract:: Solanum species differ in their degree of frost tolerance and cold acclimation capacity. Cultivated potato species of Solanum tuberosum L. are frost-sensitive, incapable of cold acclimation, and have a maximum freezing tolerance of –3°C. Solanum commersonii Dun is frost-tolerant and can survive to –5ºC pre-acclimation and –10ºC post-acclimation. Breeding attempts...
