The relative accuracy of solutions to chaotic systems was examined using the Lorenz
system as a case study. The classical fourth order Runge-Kutta method was employed to
generate solutions using various step sizes, and the resultant solutions were compared. A
second set of solutions was then computed using one of...
The Willamette Valley, bounded on the west by the Coast Range and on the east by the Cascade Mountains, is the largest river valley completely confined to Oregon. The fertile valley soils combined with a temperate, marine climate create ideal agronomic conditions for seed production. Historically, seed cropping systems in...

Proteinaceous compounds are abundant forms of organic nitrogen in soil and aquatic ecosystems, and the rate of protein depolymerization, which is accomplished by a diverse range of microbial secreted peptidases, often limits nitrogen turnover in the environment. To determine if the distribution of secreted peptidases reflects the ecological and evolutionary...
Currently, Sierra Nevada forests have high levels of mortality caused by bark beetles infesting trees stressed by drought, fire, overly dense stands, and pathogens. Fuel loads and fire hazard are high. Past logging and fire exclusion practices are partially responsible for this situation. Mitigative restoration requires thinning overly dense stands,...
Assessment of beef cow energy balance
and efficiency in grazing-extensive rangelands has
occurred on a nominal basis over short time intervals and
has not accounted for the complexity of metabolic and
digestive responses; behavioral adaptations to climatic,
terrain, and vegetation variables; and documentation of
the effects of nutrient form and...
Before developing a plan or deciding to add facilities to increase tourist potential, ask the question, "Is it worth it? Will tourism do for this community what we want done?''
The cost-benefit technique balances costs against benefits to show the estimated net effects of a plan. The study may be...
In analyzing tourism, we want to know how many visitors will be coming to visit and how much they will spend, so that we can evaluate:
• Whether existing facilities can handle the visitors expected.
• Whether it will be profitable to make preparations for increased tourists.
It is important...
The money tourists spend in a community is the benefit which people probably recognize most readily. Other benefits might include improved recreation facilities, expanded cultural and social opportunities, and pride in one's community, but additional dollars provide the usual appeal for tourism development. These dollars benefit sectors throughout the community,...
