Most residential landscapes include a combination of hardscapes
(patios, decks, walkways, and driveways) and ornamental plants. As you
think about the design, construction, and maintenance of your landscape,
consider how sustainable each component is and how it could be modified to be more sustainable.
A sustainable landscape is more than exterior decoration. By using less water, fertilizer, and pesticides than a traditional
landscape, it has minimal impact on the environment. Thus, it is both aesthetically pleasing and environmentally sound.
Creating a sustainable landscape means working toward a thoughtful balance between resources used and results...
A sustainable landscape is more than the conscious arrangement of outdoor space for human enjoyment and satisfaction. It is a landscape that uses minimal water, fertilizers, pesticides, labor, and building
materials. Creating a sustainable landscape means working toward a
thoughtful balance between resources used—both in construction and maintenance—and results gained.
The piezoelectric fatigue behavior of Pb-free ceramics based on solid solutions of Bi(Zn₀.₅Ti₀.₅)O₃-(Bi₀.5K₀.₅)TiO₃-(Bi₀.₅Na₀.₅)TiO₃ was characterized at 50 kV/cm after 10⁶ bipolar cycles. Ferroelectric compositions containing 2.5% Bi(Zn₀.₅Ti₀.₅)O₃ exhibited only minor losses in maximum strain (~10%). In compositions with 5% Bi(Zn₀.₅Ti₀.₅)O₃ that exhibit large electric field-induced strains, the electromechanical strain actually...
Background: Chronic heavy alcohol consumption is a risk factor for bone fracture.
Using a non-human primate model of voluntary alcohol self-administration, we have recently shown that alcohol consumption suppresses intracortical bone remodeling. The current study extends this investigation to asses the effect of alcohol consumption on cancellous bone mass, architecture,...
Internally recording instruments were installed in the Drake Passage in January 1979 and recovered in January 1980. Additional instruments were installed at this time for the first experiment in the Pilot Ocean Monitoring Experiment. These are to be recovered in March of 1981. The array consisted of seventy current meters...
Amendments and fertilizers applied to optimize crop production and improve soil health also supply inputs of soil organic matter (SOM) and nutrients that affect soil microorganisms. In the dairy-intensive Pacific Northwest, dairy manure is stored as slurry mixtures until conditions are appropriate for soil application. During storage, the manure begins...
Much recent research has focused on the development lead-free perovskite piezoelectrics as environmentally compatible alternatives to lead zirconate titanate (PZT). Two main categories of lead free perovskite piezoelectric ceramic systems were investigated as potential replacements to lead zirconate titanate (PZT) for actuator devices. First, solid solutions based on Li, Ta,...

Internally recording instruments were installed in the Drake Passage in January 1977 and recovered in December 1977. Additional instruments were installed at this time and recovered in January 1979. The first array consisted of 21 Aanderaa current meters on five moorings. The second array was one mooring with three current...
The work described herein details the synthesis and application of
biphenyls that probe the effects of hydrogen, Cl / Br, and methyl substituents
on the aryl ring of the terminal acetylenic carbon. From this work, we
successfully developed the rapid synthesis of phenyl acetylenes in 3-4 steps
from inexpensive commercially...

Traditional public health bacterial indicators of water quality and the Biolog® system were evaluated to compare their response to other indicators of stream condition with the state of Oregon and between ecoregions (Coast Range, Willamette Valley, Cascades, and Eastern Oregon). Forty-three randomly selected Oregon rivers were sampled during the summer...
We present genetic and morphological evidence supporting the recognition of a
previously synonymized species of Mesoplodon beaked whale in the tropical Indo-Pacific,
Mesoplodon hotaula. Although the new species is closely-related to the rare
ginkgo-toothed beaked whale M. ginkgodens, we show that these two lineages can be
differentiated by maternally (mitochondrial...

We present an optical method (optical current meter) to measure the longshore
component of nearshore surface currents by measuring the alongshore drift of persistent
sea foam in the surf zone. The method uses short time series of video data collected from
an alongshore array of pixels. These space-time data are...
In recent years, the methyl erythritol phosphate (MEP) pathway to isoprenoids has been the subject of intensive research. The interest is because isoprenoids have important roles in many cellular processes essential for the survival of several pathogenic organisms, making the inhibition of this pathway an attractive target for the drug...
The use of gas chromatography for the separation, comparison,
and subsequent identification of flavor volatiles from food
products has proven highly successful in recent years. The
development of various techniques for the concentration of the
volatiles before gas chromatographic analysis has greatly extended
the use of this important analytical tool....
Urban stormwater runoff with a high impervious area can significantly impact pollution concentrations of receiving water bodies. The use of low impact development (LID), which mimics the hydrological properties of the site before development, has been studied in an increasing number of studies, and the available database has shown to...
The data described in this report were collected in support of the program, Abyssal Boundary Current Studies, funded by the National Science Foundation. This program was designed to improve our understanding of the structure and variability of the deep western boundary currents and to estimate their transport of heat and...
