A revision of the black grass bug genus Irbisia Reuter (Heteroptera:Miridae)

Creator:: Schwartz, Michael David
Abstract:: The black grass bug genus Irbisia Reuter was revised. Over 18,000 specimens were examined and information concerning the biology, host plant and distributional relationships of the species was compiled. In addition to external characters, the male claspers and vesica, and the female dorsal libiate plate of the bursa copulatrix and...

Seasonal movements and distribution of migratory Roosevelt elk in the Olympic Mountains, Washington

Creator:: Schroer, Gregory L.
Abstract:: Seasonal movements, home ranges, core areas and habitat use patterns of hunted, migratory Roosevelt elk (Cervus elaphus roosevelti) were investigated on the Olympic Peninsula, Washington. Radio telemetry was used to obtain more than 3,100 locations of 9 elk from May 1984 - March 1985, and November - December, 1985. Radio-collared...

The Porter house in Shedd, Oregon, circa 1874

Creator:: Willson, Mary
Abstract:: The 109-year-old Porter house in Shedd, Oregon is one of few remaining, well-preserved examples of Rural Gothic architecture in the Willamette Valley. This study attempts to record its history: the economic circumstances which led the pioneering David Putnam Porter family to build this relatively large house, the family background, and...

Differential transmission of strawberry mottle virus by Chaetosiphon thomas Hille Ris Lambers and Chaetosiphon fragaefolii (Cockerell)

Creator:: Eulensen, Gustav Egon
Abstract:: The transmission of strawberry mottle virus (SMV) to Fragaria vesca L. by Chaetosiphon thomasi and C. fragaefolii was studied to determine differences between the two species. Acquisition, inoculation, and retention phases of transmission were described. In all phases, C. fragaefolii was found to be the more efficient vector. Mean transmission...

A comparison of counting methods for software science and cyclomatic complexity

Creator:: Currans, Nancy
Abstract:: This paper reviews McCabe's cyclomatic complexity and Halstead's laws; it discusses studies in current literature relating the metrics to software. The studies are reproduced using data obtained from a large software project developed in a major electronics firm. Problems that occur when deriving the metrics are discussed; the result of...

The SELCTV database : the susceptibility of arthropod natural enemies to agricultural pests to pesticides

Creator:: Theiling, Karen M.
Abstract:: Documentation of the side effects of pesticides on arthropod natural enemies has expanded rapidly since the 1950's as part of an increase in non-target side effects literature. Most reviews have been based on empirical analysis of selected literature. The SELCTV database was developed to make a larger information base accessible...

Microbiological control of food spoilage and pathogenic microorganisms in refrigerated foods

Creator:: Al-Zoreky, Nageb
Abstract:: Microgard, a commercially-available pasteurized fermented milk, was found inhibitory to gram negative bacteria such as Pseudomonas putida, some well-known foodborne pathogens (e.g. Salmonella, Yersinia and Aeromonas) and some fungi as revealed by an agar incorporation assay method. Gram positive bacteria, however, were not inhibited. Rather, some bacteria in this group...

The effects of extracellular matrix glycosaminoglycans on adhesion and histogenesis of neural retina cells

Creator:: Meisenhelder, Jill
Abstract:: Glycosaminoglycans, highly anionic long chains of repeating disaccharides, are present in the extracellular matrix of almost all vertebrate tissues. In addition to their structural role in adult tissues, these molecules have been implicated as mediators of important developmental processes such as cell migration, cell-cell recognition and adhesion, and cytodifferentiation. The...

Characterization of strains of Scenedesmus resistant to the herbicide DCMU, (3-(3,4-dichlorophenyl)-1,1-dimethylurea)

Creator:: Smith, Muriel K.
Abstract:: Three DCMU resistant mutants of the green alga Scenedesmus obliquus D₃ are characterized. The mutants exhibit a ten fold greater resistance to DCMU than the wild type strain; this is comparable to the level of DCMU resistance detected in other DCMU resistant algae. In whole cell reactions, as well as...

Factors related to the use of pediatricians as resources for child behavior problems

Creator:: Jones, Laura Lynn
Abstract:: All parents experience some problems with their children and may look to various parenting resources for guidance and reassurance (Stoltz, 1967). The literature on the problems parents experience, including tantrums, bedwetting, whining/crying, has not comprehensively explored the range and co-occurrence of child behavior problems across all ages (Kanoy and Schroeder,...
