We simulated the erosion and accretion of a natural beach using a wave-resolving
eddy-diffusive model of water and suspended sediment motion in the bottom boundary
layer. Nonlinear advection was included in this one-dimensional (vertical profile) model
by assuming that waves propagated almost without change of form. Flows were forced by...
The agricultural industry across the United States is experiencing a shortage of qualified and interested young professionals who aspire to enter the agricultural sector. Internships have largely been used as an effective hands-on learning tool, exposing college students to an array of occupational skills and expectations in hopes of creating...
For centuries wood has served as a primary structural building material in small
dwelling, large communal structures, bridges, and temporary structures. Even
today wood is the dominant material in residential construction. Despite this long
standing use of wood, non-residential multi-story construction in light of the green
building revolution has yet...
Visualizing large movement datasets with flow maps is difficult because overlapping flows create significant graphical conflicts that make accurate interpretation difficult or impossible. Interactive flow mapping applications allow users to explore large movement datasets by automatically generating flow maps from subsets of the data in response to queries by the...
The practice of literate programming is not widespread because existing literate programming systems have some undesirable characteristics such as programming language and text processor dependence and lack of flexible tools for viewing and manipulation of the source file. This dissertation describes the literate programming system AOPS (Abstraction Oriented Programming System)...
Understanding mathematics and teaching mathematics involve
numerous factors, one of which may be an individual's spatial ability.
This paper examines research conducted on the relationship between
spatial abilities and mathematics, gender differences in the area of
spatial ability, the types of experiences that may affect one's spatial
ability, and issues...
Forty Arthrobacter species isolated from Pacific and Atlantic fishery sources were examined to determine their significance in seafood. All strains were able to utilize inorganic nitrogen as the sole nitrogen source and grew in the absence of vitamins or growth factors. In addition, 78% grew on a medium containing only...
One hundred and fourteen strains of Moraxella species isolated
from marine fishery sources were investigated to determine the cause
of this organism's predominance in seafood. The nutritional requirements,
effect of pH, NaCl concentration, and temperature on growth,
utilization of carbohydrates, protein, and lipid, resistance to 12
antibiotics, sensitivity to phenethyl...
Several streams in the mixed conifer cover type of the Ochoco and Blue Mountains of central Oregon were studied to determine what effects selective harvesting of the riparian timber stand had on the amounts and distribution of coarse woody debris (CWD) in the stream. Pristine streams were measured to develop...
