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)...
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...
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...
Over 20 global ocean tide models have been developed since 1994, primarily as a
consequence of analysis of the precise altimetric measurements from TOPEX/POSEIDON and as a result of parallel developments numerical tidal modeling and data assimilation. This paper
provides an accuracy assessment of 10 such tide models and discusses...
Uptake of [14C]glycine by various size fractions of natural plankton communities was measured to determine if phytoplankton can compete effectively with other members of the plankton community for the free amino acids in seawater. The simultaneous occurrence of glycine uptake, plant pigments, and photosynthetic activity in the same size fractions,...
Climate change is a hot potato policy: the responsibility for it is constantly passed between the domestic and international realms. By definition global climate change is a global problem yet, in the US, domestic concerns are preventing federal lawmakers from taking action and presidents from taking leadership at both the...
