With the resurgence in the interest of using natural textile dyes, a solution must be found that will overcome the limitations of traditional natural dyes. This solution must also be safer for both humankind and the environment than are synthetic dyes. This study compares the colorfastness of commercially available synthetic...
Commercial methodologies for producing fungal pigments are of worldwide interest due to the desire to move away from synthetic dyes. Chlorociboria species and Scytalidium species have been reported to produce sufficient yields of pigments for commercial production and have attracted special attention because of their use in spalted wood applications....
Phytophthora ramorum is a plant pathogen that was accidentally introduced to the United States. This invasive microorganism has killed over a million trees in California and Oregon, and continues to spread to new areas. Diseased areas have been nationally quarantined to prevent further spread and more than ninety countries include...
School forests in South Korea are trees and vegetation areas within schoolyards, and they provide natural environments for schools and neighborhoods. After the Korea Forest Service (KFS) and local governments create these school forests, the management of school forests transfers to the host schools. Some studies suggest that experiences with...
Fungi from the genus Chlorociboria are known for their production of the blue-green quinonic pigment xylindein. Extracted xylindein has been the subject of investigations ranging from fabric dying to use a coloring agent in paint, and shows potential as an organic semiconductor in organic photovoltaics (OPVs) and other technologies. However,...
With the rapid development of new computer mediated technologies, instructors have more options of the modalities of responding to student writing. Whereas traditionally, responses have been written by hand, technological developments allow responses to take very different forms. Some of these technologies, such as word processing, mimic the text-on-page techniques...
The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate.
The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...
The clean label movement is a persistent, consumer-driven trend that has shifted consumer preferences in favor of foods considered to be more natural. Although lacking legal definitions in food labeling, the terms “natural” and “clean label” are generally used to characterize foods that have short, minimal ingredient lists containing simple...
Over 470 dams have been removed in the United States, and a significant increase in dam removals has
occurred since the early 1990s. The aging of dams is often cited as the primary factor influencing removals;
as dams surpass their functional life span, safety hazards, economic costs, and environmental concerns...
The social sciences have the capacity to contribute to natural resource management through investigations of human dynamics associated with the environment. Sense of place (SOP), the formed relationships between an individual and the environment, has been considered a fundamental aspect of human well-being and can contribute to more holistic understanding...
There are many different organizations and agencies which share responsibility for educating the public about responsible use of aquatic and marine resources. However, organizations specifically focused on particular dimensions of water use, such as Oregon State Marine Board (OSMB), often face challenges when attempting to recruit teachers to implement educational...
The goal of this research is to understand factors influencing the use of TEK in
natural resource management collaborations between tribes and federal agencies. This includes what evidence exists that TEK is being used, what tribal factors influence the use of TEK, what agency factors influence the use of TEK,...
Wild turkeys (Meleagris gallopavo) were first successfully introduced into Oregon and Washington in the 1960s; the population has grown in size and expanded in distribution to a point where it provides an important recreational hunting opportunity in both states that generates significant funds for habitat conservation and contributes financially to...
Infestations of the western pine shoot borer (Eucosma sonomana Kearfott) in young stands of ponderosa pine (Pinusponderosa Lawson), were surveyed on the Deschutes National Forest. Elevation, slope, aspect, tree height, tree diameter, number of shoots in the terminal whorl, stand density, stand age and plant association for each stand were...
