Periodate oxidation of cellulose - a complete kinetic study

Creator:: Chandan, Bhaskar Arjundev
Abstract:: The effect of over-oxidation on periodate oxidation of cellulose was studied. It was found that the over-oxidation process has a significant effect on the overall reaction. An integrated rate equation was formulated. The oxidation of internal glucose units is second-order overall, first order with respect to both periodate and cellulose;...

Essential oil components of Alaska cedar heartwood

Creator:: Xiong, Yeping
Abstract:: The essential oil of Alaska cedar heartwood is known to contain compounds which contribute to the remarkable durability of this species. While previous research has identified several compounds, a complete description of this oil, which has a "burnt-grape fruit" odor, has not been undertaken. In this research a profile of...

The Effects of Prostaglandin F2α on Reproductive Performance in the Postpartum Dairy Cow and the Mechanism Behind its Benefits

Creator:: Younger, Kathryn Genevieve
Abstract:: During the beginning of the postpartum period, 80 to 100% of lactating dairy cows have bacterial contamination within their uteri. Presence of uterine bacteria may contribute to increased number of days open and services per conception within these cows. Expulsion of uterine contamination is crucial for uterine involution and reproductive...

Habitat relationships of native and non-native fishes of the Willamette River, Oregon

Creator:: Williams, Joshua E.
Abstract:: The Willamette River flows north between the Cascade Mountains and Coast Range of western Oregon within a 29,728-km² basin. The fish community in the geologically young basin consists of 36 native species, but introductions of non-native fishes have added 33 additional species for a total of 69 fish species. During...

Early macronutrient uptake and partitioning in Glycine max L. Merr

Creator:: Schuttler, Patti L.
Abstract:: Soybeans were grown in hydroponic solutions and in perlite to devise procedures to measure plant mineral accumulation and solution depletion over time. Electron emission spectrometry and micro-Kjeldahl-autoanalyzer analytic techniques were used to monitor mineral content of individual plants and their corresponding solutions. An automated computer assisted system of converting raw...

Plant-water relations in Douglas-fir seedlings and screening selected families for drought resistance

Creator:: Hallgren, Stephen William
Abstract:: This study was divided into two parts. Part I was a quantitative description of some aspects of plant-water relations in Douglas-fir seedlings, and part II was tests of several techniques of screening selected families of Douglas-fir seedlings for drought resistance. Part I. During 20 mild summer days in 1976 at...

Evaluating the data-poor fishery stock assessment method, DB-SRA

Creator:: Owashi, Brandon R.
Abstract:: Depletion-Based Stock Reduction Analysis (DB-SRA; Dick and MacCall, 2011) is a catch-only fisheries stock assessment model that has been developed to estimate an overfishing limit (OFL) in data-poor situations. DB-SRA projects the biomass trajectories of a stock by means of a catch time series and five parameters: the instantaneous, per...

Winter supplementation and delayed weaning of an autumn calving beef herd under western Oregon conditions

Creator:: Buehner, Heidi Renata
Abstract:: Two management systems were evaluated in terms of the effects on cow condition score and body weight changes and calf growth rates. The management systems evaluated were winter supplementation of energy, winter creep feeding and delayed weaning. The calves used in this study were born in September and October of...
