MackGregoryS1983.pdf

Creator:: Mack, Gregory Stebbins
Abstract:: The Grants Pass Batholith of Cretaceous age has intruded the Triassic Applegate Group and metasedimentary rocks of the Jurassic Galice Formation in the Murphy area of Josephine County, southwest Oregon. The Applegate Group, mafic volcanic and sedimentary rock, has been partially (nonequilibrium) metamorphosed under greenschist facies conditions. The batholith, a...
Full Text:: conductance (EC), pH, temperature, and HCO3 were measured on 43 samples of well water and Applegate River

Shallow Aquifer Recharge from Irrigation in a Semi-arid Agricultural Valley in New Mexico, USA

Creator:: Ochoa, Carlos G., Fernald, Alexander G., Guldan, Steven J., Tidwell, Vincent C., and Shukla, Manoj K.
Abstract:: Irrigation percolation can be an important source of shallow aquifer replenishment in arid regions of the southwestern United States. Aquifer recharge derived from irrigation percolation can be more significant in fluvial valleys overlying shallow aquifers where highly permeable soils allow rapid water infiltration and aquifer replenishment. We used data from...
Resource Type:: Article
Full Text:: separate irrigation events at the field scale, aquifer recharge values ranged from 0 to 369 15 mm when

Water content and electrical conductivity profile measurements for dispersive media using enhanced time domain and frequency domain models

Creator:: Flugstad, Benjamin A.
Abstract:: Water conservation and water quality are rapidly increasing in importance in all areas of the world. The ability to accurately measure soil water content and salinity, over a wide variety of conditions, is key to meeting this need. A set of forward prediction models and waveform interpretation algorithms to extract...

Identification of some soluble esterases of the carrot (Daucus carota I.)

Creator:: Carino, Lourminia Almeda
Abstract:: Substrate and inhibitor specificities have been used to classify esterases. The purpose of this work was to determine the substrate and inhibitor specificities of the esterases in an aquous extract of lyophilyzed carrots. Esterase activity was determined manometrically at 37°C. The optimum pH of the carrot esterases with several substrates...
Resource Type:: Masters Thesis
Full Text:: carboxylesterases (EC 3. 1, 1. 1). The sixth esterase was similar to arylester as e (EC 3.1,1.2). An enzyme

Development of a test procedure for water sensitivity of asphalt concrete mixtures

Creator:: Al-Swailmi, Saleh H.
Abstract:: Environmental factors such as temperature, air, and water can have a profound effect on the durability of asphalt concrete mixtures. In mild climates where good quality aggregates and asphalt cement are available, the major contribution to deterioration may be due to traffic loading and the resultant distress is manifested in...
Resource Type:: Dissertation

Cultural controls for suppressing Phytophthora cinnamomi root rot of blueberry

Creator:: Yeo, John R.
Abstract:: Phytophthora cinnamomi is a soilborne pathogen that causes root rot disease of highbush blueberry (Vaccinium corymbosum L.). When new installations of susceptible blueberry cultivars are infected with P. cinnamomi, plants often fail to grow significant new tissue, greatly reducing yields over the life of the planting. Chemical fungicides are available...
Resource Type:: Dissertation
Full Text:: increase soil electrical conductivity (EC) beyond current recommended salinity guidelines for blueberries

Development of performance based test procedures for asphalt mixtures

Creator:: Kliewer, Julie E.
Abstract:: In 1987, Congress authorized a 5 year $150 million dollar research program called the Strategic Highway Research Program (SHRP). SHRP was divided into four major areas, including the asphalt research program. The asphalt research program was divided into six major research contracts, one such contract, SHRP-003A was called Performance Related...

Cyclic nucleotides, cyclic nucleotide phosphodiesterase, protein kinase, and phosphoprotein phosphatase in the central nervous system of Manduca sexta

Creator:: Albin, Edward Elmo
Abstract:: Adenosine 3', 5' -cyclic monophosphate (cyclic AMP, cAMP) and guanosine 3', 5' -cyclic monophosphate (cyclic GMP, cGMP) were quantitated in the central nervous system (CNS) of the insect Manduca sexta by competitive protein binding techniques. The M. sexta CNS was found to contain a strikingly high level of cGMP, about...

Lysozyme as an aid in preventing stuck wine fermentations

Creator:: Hetz, Uri
Abstract:: To provide a possible alternative for the antimicrobial action of sulfur dioxide in winemaking, and address the issue of stuck fermentations, I studied the efficacy of chicken lysozyme (EC 3.2.1.17) as an antimicrobial in grape juice. Two different forms of lysozyme were used: native lysozyme (NL), that is known to...

Partial purification and determination of some properties of an aminotransferase of pea (Pisum sativum L.) plants

Creator:: Matheron, Michael Earl
Abstract:: A transaminase (aminotransferase, EC 2. 6. 1) was extracted and purified approximately 148-fold from shoot tips of pea (Pisum sativum L. cv. Alaska) seedlings and some properties of the enzyme were determined. The purification included acetone precipitation followed by column chromatography on hydroxylapatite. With a-ketoglutarate as co-substrate, the acetone precipitated...
