Implications of cougar prey selection and demography on population dynamics of elk in northeast Oregon

Creator:: Clark, Darren A.
Abstract:: Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining...

Dynamic modeling, simulation and stability analysis of brushless doubly-fed machines

Creator:: Li, Ruqi
Abstract:: A brushless doubly-fed machine (BDFM) is a single-frame, self-cascaded induction machine capable of operating in both the induction and the synchronous modes. This thesis presents some important advances concerning dynamic modeling, simulation and analysis of the BDFM. Initially, a two-axis model and its associated parameters are developed and calculated. The...

Prediction of brushless DC drive performance considering non-sinusoidal parameter variations and asymmetrical operating conditions

Creator:: Spee, Rene
Abstract:: A highly flexible numerical simulation model for the performance prediction of brushless dc drives is presented, which is capable of investigating unbalanced and asymmetrical operating conditions as well as drives with non-ideal parameters. Numerical speed-up procedures allow for the investigation of pulse-width modulated (PWM) drives using a personal computer. Experimental...

The development of the chlorinity-salinity concept in oceanography

Creator:: Wallace, William J.
Abstract:: This study traces the historical foundations of the concept of constant ionic proportionality and the equation (Salinity [S%₀] = 1.805 Chlorinity [Cl%₀] + 0.030) which has been in general use in oceanography since 1902 until 1969 and which is based upon this constancy, The notion that the constituents present in...

The association of DNA with other cellular materials in Escherichia coli lysates

Creator:: Porter, Bruce Wallace
Abstract:: The association of other materials with DNA has been studied extensively in higher organisms and more recently in bacteria. However, investigation of these complexes in bacteria have for the most part been restricted to the study of a specific function this association may serve, or a specific kind of association....

The impact of maltreatment on adolescent substance abuse

Creator:: Hall, Nancy K.
Abstract:: While the general link between adolescent maltreatment and adolescent substance abuse is well established, questions remain regarding factors that may explain variability in the strength of this link. This study examines whether the link between maltreatment and substance abuse varies across three categories of maltreatment: physical, sexual and emotional. It...

The staff development needs of full-time instructional faculty as reported by professional staff members in Oregon community college

Creator:: Justice, Patricia Kallberg
Abstract:: PURPOSE OF THE STUDY: The study examined administrator and faculty perceptions toward staff development needs and ascertained the differences which exist between the reported staff development needs of full-time community college instructors within the state of Oregon. OBJECTIVES OF THE STUDY: The three objectives identified for this study were: 1....

Quantification of vegetation diversity and variation on intact and degraded rangelands

Creator:: Dysart, Patricia L.
Abstract:: Vegetation diversity in the Wyoming big sagebrush/Thurber needlegrass (Artemisia tridentata Nutt. ssp. wyomingensis Beetle & Young/Achnatherum thurberianum (Piper) Barkworth. syn. Stipa thurberiana Piper) plant association was studied across a condition class gradient in southeastern Oregon. All observable vascular plant species were counted during 6 seasons and 2 years and diversity...
