William Keith Brooks (1848-1908) : a case study in morphology and the development of American biology

Creator:: Benson, Keith Rodney
Abstract:: The major historical studies that have examined American biology have emphasized the development of experimental biology at the end of the nineteenth century. In this characterization, the descriptive branch of biology has often been treated as less than important and, in several cases, as a hindrance in the application of...

Model study of drainage in shallow layered soils

Creator:: Bonna, Ata Kusi
Abstract:: The occurrence of relatively less permeable soil underlying a relatively more permeable and shallow soil profile is widespread in the Willamette Valley Region of Oregon. Recognizing that an understanding of the water transport process in such a situation would provide reliable criteria for designing a drainage system has led to...

Hydraulic functions of soils from physical experiments and their applications

Creator:: Su, Charles
Abstract:: Based upon the Pearson Type VIII distribution function, a general retention function which relates the saturation to the capillary pressure in disturbed soils has been discovered. This simple and yet complete function has been shown to describe precisely the imbibition as well as the drainage branch of the retention curve....

Projection model assessing the need for instructors of occupational subjects in Oregon's community colleges

Creator:: Daly, Crayton Brooks
Abstract:: The major thrust of this research was to design, test, and perfect an accurate and effective assessment technique, which would result in becoming an assessment model. For the purpose of developing this assessment model, the employment need for full-time instructors of occupational subjects in the community colleges within the state...

Experimental analysis of subsurface heating and irrigation on the temperature and water content of soils

Creator:: Sepaskhah, Ali Reza
Abstract:: Multiple use of waste heat from power plants may become an important consideration in the development, siting, and certification of these plants. A multiple use system of components that can beneficially utilize waste heat may include home heating and cooling, greenhouses, animal enclosures, open basins for single cell protein production...

Feed conversion, protein utilization and growth of rainbow trout (Salmo gairdneri) fed 25 to 45 percent herring oil

Creator:: Kellems, Richard O.
Abstract:: Triplicate groups of rainbow trout (Salmo gairdneri) fed six diets; five based on fish protein concentrate (FPC) ranging in caloric density from 4.36 to 6.19 kcal/g, and one based on vitamin free casein with a caloric density of 5.26 kcal/g were evaluated with respect to diet ingredient utilization. The parameters...

Some effects of dissolved oxygen concentration on feeding, growth and bioenergetics of juvenile Coho salmon

Creator:: Thatcher, T. O.
Abstract:: The effects of three levels of dissolved oxygen (8, 5 and 3 mg/l) upon the feeding, growth and bioenergetics of juvenile coho salmon, Oncorhynchus kisutch (Walbaum), were determined in laboratory studies. Experiments with individual fish were conducted during the summer, fall and spring to measure rates of food consumption, standard...
