Suitability of diverse composts as soil amendments for highbush blueberry (Vaccinium corymbosum L.)

Creator:: Costello, Ryan C.
Abstract:: Highbush blueberry (Vaccinium corymbosum L.) is adapted to soils with high organic matter and acidic pH. Composts provide organic matter and nutrients for growing blueberry in mineral soils, but many composts are high in pH and soluble salts. Acidification with elemental sulfur (S°) can remedy high pH, but the process...

Development, performance evaluation and application of a physical model of the Kenyan-Tanzanian coastal region

Creator:: Mayorga Adame, Claudia Gabriela
Abstract:: A Regional Ocean Modeling System (ROMS) application for the coastal region of Kenya and Tanzania (0-10° S, 38.7-46.98° E) was developed with the aim of better resolving the circulation patterns in the coastal region that is poorly represented in global models. The model has a horizontal resolution of 4 km,...

Investigating Alternative Irrigation Strategies and Sources for the Cool-Humid Willamette Valley

Creator:: Olsen, Conner J.
Abstract:: Rising human populations and climate change are putting increasing demands on our already-limited freshwater sources. In response to these concerns, homeowners and municipalities have been encouraged to replace turfgrass – a plant with relatively high irrigation needs – with drought-tolerant plants that do not require frequent irrigation. However, the many...

Aryl acetylene substituent effects : the synthesis and application of biaryls

Creator:: Naffziger, Michael R.
Abstract:: 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...

Design of composite sandwich panels for a Formula SAE monocoque chassis

Creator:: Story, Robert D.
Abstract:: Physical testing of composite sandwich panels in three point bending is an increasingly important aspect of qualifying a composite monocoque for Formula SAE competition. Required stiffness and strength values have increased over the past three years, and more of the monocoque's laminates must be tested as well. As a result,...

A quantitative structure activity relationships study of antiinfectives based on the nalidixic acid structure

Creator:: Yu, Yupei
Abstract:: Nalidixic acid and its derivatives act through inhibition of bacterial DNA gyrase activity. Recently there have been a series of papers reporting the antibacterial activity against three different types of bacteria (S. aureus, E. coli and P. aeruginosa) by a series of 1,4-dihydro-4-oxoquinoline (or 1,8-naphthyridine) 3-carboxylic acids. Consistent biological data...

Factors influencing the herbicidal activity and persistence of isomers of 1, 1-dimethyl-diisopropyl-indanyl ethyl ketone in soil

Creator:: Donaldson, Dean Robert
Abstract:: The purpose of this study was to evaluate the activity of Sindone (isomers of 1, 1-dimethyl-diisopropyl-indanyl ethyl ketone) under field conditions and to gain information regarding the rate of detoxification of Sindone in soil. A series of trials were established in sugar beet fields in California, Oregon, and Washington. Sindone...

Influence of ankle orthoses on ankle joint motion and postural stability before and after exercise

Creator:: Jorden, Ryan A.
Abstract:: Ankle injuries comprise more than 15% of all sports injuries worldwide. The efficacy of the ankle taping for injury prevention has long been under scrutiny as numerous studies have shown that tape rapidly loses its ability to constrain ankle motion with exercise. Consequently, ankle braces (orthoses) are being used with...
