Sediment transport in streams in the Umpqua River Basin, Oregon

Creator:: Onions, C. A. and Douglas County (Or.)
Abstract:: This report presents tables of suspended-sediment data collected from 1956 to 1967 at 10 sites in the Umpqua River basin. Computations based on these data indicate that average annual suspended-sediment yields at these sites range from 137 to 822 tons per square mile. Because available data for the Umpqua River...

The effect of etches on surface recombination in silicon

Creator:: Cheng, Dan Sang
Abstract:: This thesis presents a limited investigation of the effects of various etches on the surface properties of silicon. Surface recombination velocities of silicon under different etching treatments are compared by using the photoelectromagnetic effect. A measure of the minority carriers lifetime by the photoconductive decay method provides another means of...

The design, construction and calibration of a low-energy, low exposure-rate ionization chamber

Creator:: Clarke, Arthur Porter
Abstract:: A low-energy, low-exposure-rate, guarded-field ionization chamber system with a sensitive volume of approximately 1040 cm³ and an exposure-rate range from 60 mR/h to less than 0.5 mR/h was designed, constructed and calibrated. The calibration was effected by constructing and calibrating a 60 cm³ volume transfer chamber of similar design against...

The influence of tree cover and shade pattern upon the distribution of understory plants in ponderosa pine stands of central Oregon

Creator:: Robinson, Andrew Frederick, Jr.
Abstract:: Seven sites of uniform topography and soil were selected within a self perpetuating ponderosa pine forest found on the eastern flank of the central Oregon Cascades. These plots were located along a vegetational gradient caused mainly by an orographic rain shadow. Data gathered included density, frequency, and cover for all...

The successful teacher in technical education : the preparation of the successful teacher

Creator:: Storm, George, 1923-
Abstract:: The purpose of this study was to assist the development of an improved technical teacher education program. Specifically, the project sought to determine what, if any, factors in the backgrounds of successful technical teachers may have accounted for their success in teaching. To provide information to this end, the investigation...

A linear circuit analysis program for a small computer with no auxiliary memory

Creator:: Stubkjaer, William Lloyd
Abstract:: A set of circuit analysis programs designed for the IBM 1620 computer (having 40,000 digits of memory) is described and its operation is explained. The set consists of d-c, a-c, and transient analysis programs. The d-c and a-c analysis programs provide the branch current and node-to-reference potential for linear circuits....

A portable dual-range fuel flowmeter for automotive research

Creator:: Hodgkins, Chester
Abstract:: This describes the development of a new fuel flowmeter. Among the desired features were an accuracy of ±2%, a linear response to fuel flow rate, a means of increasing the sensitivity at the low end of the meter scale and portability so that it would be equally useful in the...

An interindustry analysis of the importance of grazing on federal lands to the economy of Grant County, Oregon

Creator:: Bromley, Daniel W., 1940-
Abstract:: Use of federal lands for commercial and recreational activities contributes significantly to the economic stability of many rural areas. Recent increases in demand for recreational use have created conflicts between uses and among users. Some are questioning the use of public land for private gain. The seemingly low grazing fees...
