Customer requirements and engineering specifications will influence the direction of the design in any product, so it is crucial to make the requirements as stable as possible so quality designs can be produced on time within a budget. It would be optimal for requirements and specifications to remain constant but...
Since harvest levels of many of the world's fisheries are not likely to increase in
the foreseeable future, resource managers and seafood processors need to develop
improved strategies to maximize the utilization and benefits of current catches. In
addition to increasing utilization and benefits, seafood processors are subject to the...
OBJECTIVES: The current study examined disparities in smoking trends across African Americans and non-Hispanic whites in California.
METHODS: Data from the 1996 to 2008 California Tobacco Survey were analyzed to examine trends in smoking behaviors and cessation across African Americans and non-Hispanic whites.
RESULTS:
A decrease in overall ever and...
Estimates of three components of an uncertainty budget for a coastal ocean model in a wind-forced regime
are made based on numerical simulations. The budget components behave differently in the shelf regime,
inshore of the 200-m isobath, and the slope-interior regime, between the 200-m isobath and a fixed longitude
(1268W)...
The predictability of coastal ocean circulation over the central Oregon shelf, a region of strong wind-driven
currents and variable topography, is studied using ensembles of 50-day primitive equation ocean model
simulations with realistic topography, simplified lateral boundary conditions, and forcing from both idealized
and observed wind time series representative of...
In partially migratory species, such as Oncorhynchus mykiss, the emergence of life history phenotypes is often attributed
to fitness trade-offs associated with growth and survival. Fitness trade-offs can be linked to reproductive tactics that vary between
the sexes, as well as the influence of environmental conditions. We found that O....
Although climate acts as a fundamental constraint on the distribution of
organisms, understanding how this relationship between climate and distribution varies over a
species’ range is critical for addressing the potential impacts of accelerated climate change on
biodiversity. Bioclimatic niche models provide compelling evidence that many species will
experience range...
We test hypothetical tsunami scenarios against a 4,600-year record of sandy deposits in a southern Oregon coastal lake that offer minimum inundation limits for prehistoric Cascadia tsunamis. Tsunami simulations constrain coseismic slip estimates for the southern Cascadia megathrust and contrast with slip deficits implied by earthquake recurrence intervals from turbidite...
Alternative male phenotypes in salmonine fishes arise from individuals that mature as larger and older anadromous marine-migrants or as smaller and younger freshwater residents. To better understand the processes influencing the expression of these phenotypes we examined the influences of growth in length (fork length) and whole body lipid content...
