The Direct/Delayed Response Project (DDRP) has been designed and implemented to estimate the number of lakes and streams that might become acidic in three regions due to current or altered levels of acidic deposition. As part of DDRP, 145 watersheds in the northeast US were mapped at 1:24,000 for soils,...
Research studies indicated that teachers' sense of self-efficacy is a multidimensional construct related to teachers' beliefs about teaching, their ability to teach, and their students' ability to learn. This study described the change in a cohort of graduate preservice elementary teachers' sense of efficacy as they progressed through a four...
The exact frequencies and mode shapes of flexural vibration of a
rotating beam are found. The beam has a linear mass and stiffness
distribution.
With certain simplifying assumptions, the kinetic and potential
energies of the rotating beam are found. Hamilton's principle is then
used to determine the equation governing the...
The upper drainage of the John Day River system produces summer steelhead and spring chinook salmon. The fish are generally confined to the main stem and its tributaries above Prairie City. The spawning and rearing areas are comparatively free of undesirable fish species, but salmonid smolts migrating downstream must travel...
Clear Creek, tributary of North Fork John Day River, is a mountain stream located in the Blue Mountains of eastern Oregon. It joins Granite Creek about 1.5 miles below the old abandoned mining town of Granite. Gravel removed from Clear Creek by gold dredging activity was replaced in a 3.37-mile...
The project objectives were to determine the possibility of raising the subterranean water in adequate amounts by installation of an underground weir; to determine what type of structure would be most feasible; and to formulate a biological evaluation program if the first two objectives were accomplished. Tex Creek, tributary to...
