An investigation of vegetation : hydrology interactions in watershed 1 at the H.J. Andrews Experimental Forest

Creator:: Bredensteiner, Kim C.
Abstract:: For management purposes, it would be useful to be able to predict streamflow response to forest practices in small, unmonitored basins. The primary objective of this study is to investigate the influence of early successional vegetation on summer streamflow levels. The long-term data records from watershed 1 at the H.J....

Modeling climate, vegetation, and water balance at landscape to regional scales

Creator:: Daly, Christopher
Abstract:: The general objective of this study was to develop models and datasets that would significantly advance our ability to assess the current and future effects of global change on the biosphere. The focus was in two areas: (1) preparing environmental datasets at regional to small watershed scales; and (2) developing...

A Comparison of Client Follow-up and Selected Components of Weight Control Programs Managed by Dietitians and Nondietitians in Oregon

Creator:: Leland, Ronald Wayne
Abstract:: Obesity affects one out of every four Americans and represents a serious health hazard in the United States. Serious chronic diseases associated with obesity include heart disease, cancer, and adult-onset diabetes mellitus. There has been a rapid expansion in the number of weight control centers since the 1970s, yet there...

Evaluation of water damage on asphalt concrete mixtures using the environmental conditioning system

Creator:: Al-Joaib, Ali Abdulla
Abstract:: Asphalt concrete pavement is subjected to several damaging actions from traffic loads, water (from precipitation and/or groundwater sources), and temperature. The durability of the asphalt-aggregate mixture, its ability to withstand these damaging actions for long periods, is a very important engineering property. While the durability of the asphalt-aggregates mixture depends...

Water and solute transport : modeling and application to water conservation in layered soil

Creator:: Mohammed, Fareed H. A. N.
Abstract:: Sandy soils are among the least productive soils because of their inability to store adequate water for plant growth. Their high percolation rate not only allows water to move quickly beyond the root zone, but also washes nutrients below the reach of plant roots. High evaporation occurs from the soil...

Development of a process for production of cantaloupe juice concentrate and determination of its composition and quality

Creator:: Galeb, Abduljalil Derhm Saeed
Abstract:: Fresh ripe, cantaloupes were processed into juice and juice concentrate. Processing trials were conducted on fresh and frozen fruits with and without rind. The effects of maceration enzymes and fining agents on yield and quality were investigated. Compositional measurement included °Brix, pH, titratable acidity, formol values, ascorbic acid content, total...

Structure and conformation of red radish (Raphanus sativus L.) anthocyanins and their effect on color and pigment stability

Creator:: Giusti Hundskopf, Maria Monica
Abstract:: Red radish (Raphanus sativus L.) anthocyanins were extracted from liquid nitrogen powdered epidermal tissue using acetone and chloroform and isolated using C-18 resin. Chemical structure and conformation of major pigments were elucidated by 1-D and 2-D NMR, Mass Spectroscopy, HPLC, and spectral analyses. Two novel di-acylated anthocyanins, pelargonidin 3-0-[2-0-(β-D-glucopyranosyl)-(6-0- trans-p-coumaroyl-...

Extending shelf-life of fresh-cut pears

Creator:: Dong, Xiaoling
Abstract:: Different concentrations of various browning inhibitors and a firming agent were evaluated to prevent browning and softening of Bartlett, Bosc and Anjou pear slices during cold storage at 2-4°C. Browning inhibition effect of Semperfresh, Snow Fresh and cysteine were compared with that of 4-hexylresorcinol (4-HR). The effect of ripeness on...

The potato : composition, non-enzymatic browning and anthocyanins

Creator:: Rodriguez-Saona, Luis Enrique
Abstract:: Chipping varieties and model systems were used to determine the role of potato constituents on chip color. Composition was evaluated by HPLC and chip color measured using a ColorQuest colorimeter. Reducing sugar (RS) content did not completely explain color quality when present in low concentrations (<60 mg/lOOg). Levels of ascorbic...

Radish anthocyanin extract as a natural red colorant for maraschino cherries

Creator:: Hundskopf, Maria Monica Giusti
Abstract:: Red radish anthocyanin extract (RAE) was investigated for coloring brined cherries as an alternative to FD&C Red No. 40. Red radish (Raphanus sativus L.) anthocyanins were extracted from liquid nitrogen powdered epidermal tissue using acetone, partitioned with chloroform, and isolated using C-18 resin. The monomeric anthocyanin content was determined by...
