The Upper Kiamath Valley and Klamath Marsh areas of
south-central Oregon comprise the summer range for a modern
system of transhumance agriculture. Approximately 72,000
head of cattle are annually trucked from these relatively
small Kiamath pastures to winter pastures scattered throughout
the Sacramento Valley. Field research indicates that
the development...
The purpose of this thesis was (1) to determine a dietary regimen which would produce the greatest incidence of cardiac calcification in the cotton rat and (2) to determine the fatty acid composition of heart tissue.
Maximum incidence of cardiac calcification occurred from feeding torula yeast ration supplemented with 0.5%...
The primary purpose of this study was to determine if inservicing Agriculture Science and Technology (AST) teachers over a new curriculum, resulted in increased student achievement. Specific objectives were to: 1) determine the subject areas (lessons) for a curriculum for teaching Integrated Pest Management (IPM); 2) develop a curriculum for...
The 4-H Yukon River Fisheries Education and Youth Development
Program is a federally funded youth-at-risk program created to help youth
escape from the social ills of substance abuse, teen pregnancy, low
academic achievement, and suicide that plague rural Alaskan villages. By
providing youth the opportunity to learn the skills needed...
The purpose of this research was to explore
non-persistence by vocational students in the College of Career
and Vocational Education at the University of Alaska Anchorage.
A cohort of 156 students were identified and tracked from fall
1989 through spring 1992.
In the first part of the study, using the...
Basic Skills—Level 1.
This fact sheet is intended for use by Oregon 4-H members enrolled in the clothing project. It explains how to select the correct pattern size, read a pattern envelope, understand pattern symbols, and use the pattern guidesheet.

Welcome to the beginning 4-H outdoor cooking project—S’mores and More! If you haven’t yet experienced the joys of cooking outdoors, here’s your opportunity to roast marshmallows, make your own S’mores, and so much more!
The goals of the Of People and Fish program are for youth and adults to understand the complex cultural and scientific history that has led to the “salmon crisis” and to become active citizens in the search for solutions within their communities.
Curriculum introduces adults and youth to the science and function of wetlands, streams and oceans, and how human activities affect climate and environmental function and health.

We report zero kinetic energy (ZEKE) photoelectron spectroscopy of benzo[h]quinoline (BhQ) via resonantly enhanced multiphoton ionization (REMPI) through the first electronically excited state S₁. From the simulated REMPI spectra with and without Herzberg–Teller coupling, we conclude that vibronic coupling plays a minor but observable role in the electronic excitation to...
Na⁺/H⁺ antiporters are ubiquitous membrane proteins that play a central role in the ion homeostasis of cells. In this study, we examined the possible role of Na⁺/H⁺ antiport in Yersinia pestis virulence and found that Y. pestis strains lacking the major Na⁺/H⁺ antiporters, NhaA and NhaB, are completely attenuated in...
Air temperatures at i m and soil temperatures at 2C cm are reported for
twenty-one forest stands in the central Western Cascader of Oregon. Records
began in 1970 for some stands, in 1971 or 1972 for most. Temperature Growth
Index for a stand, based on temperature effects on Douglas-fir seedling...
Phytoplankton initiate the marine carbon cycle by fixing carbon dioxide into biologically available compounds. These abundant single celled organisms mediate carbon flux from the atmosphere to the deep ocean and are the base of the marine food web, supplying new carbon to higher trophic levels. Phytoplankton are highly diverse and...
This thesis experimentally determines the feasibility to creating C4 to C10 hydrocarbons from CO2, CO, H2, H2O and CH4. This is done in two steps, the initial step is the formation of ethylene through DC electrical glow discharge at ambient pressure while the second step is through temperature pulse controlled...
Mass timber is emerging as a viable form of construction around the world in new markets for wood buildings. The entrance into these markets has driven the demand for more knowledge to enable designs alongside other structural materials such as steel and reinforced concrete.
Large, in-plane tests on cross-laminated timber...
Nursery plants are often harvested, stored, and shipped bare-root for easier and more economical handling. Some species of woody and herbaceous perennials are less tolerant of postharvest handling than others. Desiccation stress during the handling of bare-root plants has been identified as a major problem contributing to poor survival and...
Stem mapping of all trees greater than 15 cm dbh has
been completed on the 10.24 hectare watershed (No. 10) at H. J.
Andrews intensive study site. Using a 25 m grid system, mapping
of vegetation into 7 plant communities and then into 4 habitat
types has also been completed....
Throughout Europe, Northern Africa, and the Near East, hundreds of Roman ruins lie scattered about. Many Roman aqueducts, bridges, roads, and even buildings remain standing over two thousand years after their construction, as functional as the day they were built. In the modern United States, however, many public works projects...
Clay mineral genesis was studied in soils representative of several
different geomorphic surfaces in western Oregon, ranging in age from
Pliocene-early Pleistocene to late Pleistocene. Soil solution studies,
clay mineralogy, and soil raicromorphology were employed to provide
evidence of clay mineral synthesis and interpret soil genesis.
Soils at each study...
Distribution and characteristics of soils were determined across
a series of six coastal terraces in Curry Co., Oregon.
Classification of soils and interrelationships of properties were
determined. Soil-landscape relationships were examined and soil
profile development related to relative ages of terraces. Ten pedons
were sampled from five terraces of Pleistocene...
Each year, whether it be under voluntary or unvoluntary circumstances, countless professional athletes retire from their sport. Even by the average retirement age of 30, many are still underprepared to face the challenges that accompany the transition. Along with the changes in schedule, identity, and social group, numerous professional athletes...
A prototype real-time process monitoring emergency
classification expert system, RT/EM-CLASS, has been developed
for use at the Trojan Nuclear Power Plant. This knowledge-based
system features the integration of electronically sensed plant
data with the menu selection data representation of its
predecessor, EM-CLASS. This prototype demonstrates the
techniques required to acquire...
