Homeowners have a multitude of options for pest control. This guide suggests ways to control garden pests using safe and ordinary household chemicals. The good news is that the ingredients needed can be found in your kitchen or medicine cabinet. Examples include baking soda, beer, vegetable oil, chile peppers, vinegar,...
Skunks, opossum, raccoons, coyotes, deer, and elk often are lumped into the unofficial taxonomic family “nuisance wildlife.” Actually, any kind of wildlife can fit this description, from rattlesnakes to woodpeckers, and even beavers. Most often, however, problems caused by nuisance wildlife can be managed or avoided altogether.
The hypothesis that inoculation of transplants with vesicular-arbuscular mycorrhizal (VAM) fungi before planting into saline soils would alleviate salt effects on growth and productivity was tested on lettuce (Lactuca sativa L.) and onion (Allium cepa L.). A secondary hypothesis was that the fungi isolated from a saline soil would be...
Many cranberry growers on the Oregon coast are well aware that good pollination is necessary for quality fruit set. Multiple
visits to the flower deliver more pollen, which can increase the percentage fruit set, number of seeds per berry, and mature
berry weight. The better a bee is at delivering...
A temporal record of oxygen and NO3- concentrations in the bottom water of the Santa Barbara Basin indicates that outside waters spill over into the basin seasonally. It is proposed that an annual bottom-water cycle leads ultimately to varve production.
As evidence in support of a benthic mechanism for varve...
Atmospheric particulate matter, collected over the polluted east Asia/Pacific region in spring 2001 during research flights with the National Center for Atmospheric Research (NCAR) C-130 aircraft, was analyzed for different types of organic compounds using capillary gas chromatography–mass spectrometry. More than 70 organic species were detected in the aerosols and...
Solvent extraction is an integral chemical and biochemical separation process that is drastically intensified in microfluidic systems. A novel high-throughput micro-separator was additively manufactured for the intensification of liquid–liquid separation. The micro-posts array within the flow plate generated a capillary pressure gradient on the non-wetting organic phase, enabling continuous, membrane-free,...

Direct simulations are used to study turbulence and mixing in Holmboe waves. Previous results showing that mixing in Holmboe waves is comparable to that found in the better-known Kelvin–Helmholtz (KH) billows are extended to cover a range of stratification levels. Mixing efficiency is discussed in detail, as are effective diffusivities...
The movement of moisture into, out-of, and within forest ecosystems is modulated
by feedbacks that stem from processes which couple plants, soil, and the atmosphere.
While an understanding of these processes has been gleaned from Eddy Covariance
techniques, the reliability of the method suffers at night because of weak turbulence....

The purpose of the study was to develop a system and procedure for classifying and cataloguing the textile, costume, and slide collections of the Clothing, Textile, and Related Arts (CTRA) Department at Oregon State University. Investigation was made by letter, personal visit, interview with faculty and curators, and literature research...
FragariaCyc is a strawberry-specific cellular metabolic network based on the annotated genome sequence of Fragaria vesca L. ssp. vesca, accession Hawaii 4. It was built on the Pathway-Tools platform using MetaCyc as the reference. The experimental evidences from published literature were used for supporting/editing existing entities and for the addition...

Background: The aim was to investigate possible associations between glioma (an aggressive type of brain cancer) and occupational exposure to selected agents: combustion products (diesel and gasoline exhaust emissions, benzo (a) pyrene), dusts (animal dust, asbestos, crystalline silica, wood dust) and some other chemical agents (formaldehyde, oil mist, sulphur dioxide)....

This thesis brings together under one cover a survey of the
history of the real number pi along with a study of the present state
of its theory, application, and calculation.
Accurately estimating evapotranspiration (ET) at large spatial scales is essential to our understanding of land-atmosphere coupling and the surface balance of water and energy. Comparisons between remote sensing-based ET models are difficult due to diversity in model formulation, parametrization and data requirements. The constituent components of ET have been shown...
The paper analyses the annual accounts for the period 1990-94 of a sample of approximately 100 fishing firms operating out of ports in Schleywig-Holstein and exploiting finfish stocks in the North Sea and Baltic, and shrimp stocks in the North Sea. Detailed information is provided on costs and returns by...
