Background: Functional annotations of large plant genome projects mostly provide information on gene function
and gene families based on the presence of protein domains and gene homology, but not necessarily in
association with gene expression or metabolic and regulatory networks. These additional annotations are necessary
to understand the physiology, development...
β-chitin/chitosan extracted from newly utilized jumbo squid (Dosidicus gigas) pens were investigated in respect to their physicochemical properties, polymeric structures, deacetylation and depolymerization characteristics, and antioxidant and antibacterial activities. These functional properties were further compared with α-chitin/chitosan prepared from shrimp shells. Due to the low mineral content (< 1%) and...

Best available copy. In 1984, longstanding concerns about pollution in Yaquina Bay impelled the U.S. Food and Drug Administration to make a comprehensive sanitary survey of the Yaquina River, with particular emphasis on areas where oysters were grown. The report states that the oyster plots endured "sporadic poor water quality,"...

We have developed VitisCyc, a grapevine-specific metabolic pathway database that allows
researchers to (i) search and browse the database for its various components such as
metabolic pathways, reactions, compounds, genes and proteins, (ii) compare grapevine
metabolic networks with other publicly available plant metabolic networks, and (iii)
upload, visualize and analyze...
The goal of this research is to develop an equation describing the
two, dimensional motion of an inviscid incompressible fluid in the
rectangular wavemaker of constant depth. The boundary value problem
of the rectangle is transformed to the upper half plane with the use
of Jacobian elliptical functions. The boundary...
This dissertation describes patterns in epiphytic macrolichen community composition along a nitrogen deposition gradient in the Yosemite region of the Sierra Nevada in California.

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,...
Biosolids are a by-product of municipal wastewater treatment. They contain organic matter and nutrients that are beneficial for soil, crop, and livestock productivity. Raw sewage solids must be processed to meet U.S. Environmental Protection Agency (USEPA) standards before they can be called biosolids. This publication focuses on how biosolids can...
Responses to two cycles of mass selection for heading date,
followed by selfing or intermating, were studied in two diverse
winter wheat (Triticum aestivum L. em. Thell) crosses. Selection
was bidirectional, resulting in early and late populations for
each mating system, cycle, and cross. The influence of mass
selection for...
Port Orford cedar (Chamaecyparis lawsoniana) has a reputation for being resistant to fungal attack, but much of the work to support this premise used older growth material (80-100 yr old). Given the tendency for the heartwood from the second growth of some species to be less durable, we evaluated the...

Irrigated agriculture constitutes the greatest consumptive water use globally, so that irrigation efficiency measures are an important part of global efforts to best utilize this limited resource. However, greater irrigation efficiency must be achieved while simultaneously maintaining or increasing crop yields and farming profitability. Incremental water use decisions are made...
Case control studies of nonagenarians and centenarians provide evidence that long‐lived individuals do not
differ in the rate of disease associated variants compared to population controls. These results suggest that an enrichment
of novel protective variants, rather than a lack of disease associated variants, determine the genetic predisposition to
exceptionally...

The influence of irrigation frequency (same amount of water per day given at different times) and nitrogen (N) fertilizer rate on water stress [stomatal conductance (gs)], N uptake, and growth (biomass) of container-grown evergreen Rhododendron 'P.J.M. Compact' and 'English Roseum' and deciduous Rhododendron 'Gibraltar' was evaluated. Both N deficiency and...
Wood is a major pool of organic carbon that is highly resistant to decay, owing largely to the presence of lignin. The only organisms capable of substantial lignin decay are white rot fungi in the Agaricomycetes, which also contains non–lignin-degrading brown rot and ectomycorrhizal species. Comparative analyses of 31 fungal...

Using phenolic scavengers different methods were examined to determine the optimum conditions for extracting polyphenol oxidase (PPO) from d'Anjou pears. Efficiency of the extraction was evaluated based on browning of the extract, PPO activity per g of pear tissue, absorption scan of 410 nm to -240 nm, and the isozyme...
Using a spectrometer and photomultiplier tube, I measured the electromagnetic radiation transmittance properties of three types of tissue-- ventral skin, cardiac muscle, and liver tissue--in the red-sided garter snake Thamnophis sirtalis parietalis between the wavelengths of 450 and 850 nanometers (nm). Control readings were taken using a 10⁻² neutral density...
Spider wasps had long been proposed to originate in the mid-Cretaceous based on the Burmese amber fossil Bryopompilus interfector Engel and Grimaldi, 2006. We performed a morphological examination of this fossil and determined it does not belong to Pompilidae or any other described hymenopteran family. Instead, we place it in...
Three aspects of lotic ecology have been analyzed utilizing data collected from totally autotrophic-based streams maintained by the Weyerhaeuser Company: energy transfer, effects of nitrogen addition, and simulation
modeling. All three streams had very similar periphyton, grazer, collector,
invertebrate predator, and vertebrate predator (fish) communities during
the study period (1972-1974)....
Eccentric rate of force development (ECC RFD) is a measure of the rate at which muscles can generate decelerative forces. However, it has traditionally been measured while jumping on force plates, which are not easily accessible or easy to use in a practical setting. With technology advancements it may be...

South Pacific intraplate volcanoes have been active since the Early Cretaceous. Their HIMU-EMI-EMII mantle sources can be traced back into the West Pacific Seamount Province (WPSP) using plate tectonic reconstructions, implying that these distinctive components are enduring features within the Earth's mantle for, at least, the last 120 Myr. These...
Studies using the pluripotent embryonic carcinoma cell line, P19, as a retinoic acid (RA)-responsive model system have been instrumental towards our understanding of the RA-dependent signaling pathways in development and homeostasis. Grp1-associated scaffold protein (GRASP; also known as Tamalin) was first identified by our group, as a gene robustly induced...
