Hop, Humulus lupulus L. is a dioecious perennial species. The female hop plant produces flowers that mature into ‘cones’ which are used as a raw material in the beer brewing process to impart bitterness, flavor, and aroma. The craft beer industry in the current global beer market continues to experience...
Genetic and morphological characteristics of an architectural mutant in common beans were studied. The mutant had shiny, dark green leaves, overlapping leaflets, short petioles and a reproductive terminal bud even though the line did not carry the fin gene. Branching was nearly absent resulting in a single stem vine. This...
An apparatus and method for calibrating planar laser induced fluorescence using a two-dye, two-color method was developed. A laser sheet was expanded from a 473 nm laser to excite dye solutions into higher energy states then fluoresced through spontaneous emission. The two fluorescent dyes selected for research and development were...
The severity of wildfires around the globe is increasing. At the same time, urban development is expanding outward into areas where severe fires occur. There is an increased risk of home loss to fires in areas where severe fires and urban expansion meet. Ignition of homes or nearby fuel is...
Thymidine kinase is a key enzyme in the nucleotide salvage pathway,
catalyzing the production of dTMP from thymidine and ATP. In order to
identify the structural features of the TK protein and/or primary amino
acid sequences which contribute to the catalytic and regulatory activities of
this enzyme, an in vitro...
Background: Body Mass Index (BMI) is used as a quick and inexpensive tool to measure populations at risk for a number of metabolic and chronic conditions. In part due to its simplicity, BMI has been criticized for its inaccurate prediction concerning health outcomes. Due to the diversity in the United...
β-catenin is a multi functional protein that is involved in cell-cell adhesion and cell signaling. In non-stimulated cells, β-catenin is tightly down-regulated by GSK-3β-dependent phosphorylation at Ser and Thr residues, followed by rapid ubiquitination and proteasomal degradation. It is well established that mutations within the regulatory GSK-3β region lead to...
The persistent color (pc) trait in snap bean (Phaseolus vulgaris L.) belongs to a member of the cosmetic stay-green gene family. It is considered very desirable by snap bean breeders for its impacts on pod quality. Persistent color imparts a uniform dark-green color to pods and expresses in seeds as...
Health care providers, including complementary and alternative medical (CAM) practitioners, exert a significant influence on parental pediatric vaccination decisions. Use of CAM therapies is increasing in Oregon. Concomitantly, there has been a decade-long increase in parental vaccine refusal in Oregon, rising from 1 to 5 percent from 2000-2009. For example,...
Advances in technology such as 3D digital scanning and spatial analysis software have provided archaeologists with novel data. Specifically, these methods increase the researcher's ability to measure artifact morphology and past networks of cultural transmission, to potentially track the movement of past peoples and ideas through space and time. This...
Interspecific hybridizations between P. vulgaris and P. acutifolius
and between P. vulgaris and P. lunatus were investigated. Prefertilization
events were similar in inter- and intra-specific crosses. Fertilization
was completed in all crosses and the time of fertilization was
dependent on the maternal parent, reflecting differences in the time of
maturation...
Mutation of repetitive DNA by repeat-induced point mutation (RIP) is a process that occurs in many filamentous fungi of the Ascomycota during the sexual cycle. Concurrently, direct DNA repeats are often deleted by homologous recombination at high frequency during the sexual cycle. Thus, the processes of RIP and deletion compete...
The effects of modifying air temperature, soil temperature,
and soil moisture levels on flowering, fruiting, and chemical composition
of Tendercrop snap beans were studied in experiments in
the field and in the greenhouse during 1961, 1962, and 1963.
High maximum temperatures of 95-105° F. during bloom reduced
the percent set...
Mutation analysis is the gold standard for evaluating test-suite adequacy. It involves exhaustive seeding of all small faults in a program and evaluating the effectiveness of test suites in detecting these faults. Mutation analysis subsumes numerous structural coverage criteria, approximates fault detection capability of test suites, and the faults produced...
Declines in Greater Sage-Grouse (Centrocercus urophasianus, hereafter sage-grouse) populations could be attributed to low chick survival, which may be influenced by the availability of food and cover at sites used by females rearing broods. Habitat attributes important to broods may vary regionally; thus, it is necessary to understand factors affecting...
