An apparatus was designed to permit freezing tests of
needles and other tissue parts from coniferous trees under
controlled rates of temperature change with time. The design
is based on the principle of a balanced system of refrigeration
demand and heat input to achieve a steady temperature state.
The apparatus...
Both leave islands, or green tree retention clusters, and thinning prescriptions have been proposed as alternative silvicultural strategies designed to sustain the structural and biological diversity of managed forests. However, the relationship of the physical structure of leave islands and thinned forests to their associated microclimates, flora, and fauna remain...
William James came of age at a time of great social and intellectual change in the United States. During this period, new professional identities proliferated, and a new culture of professionalization developed with important ramifications for conceptions of individual and social identity. Professionalization was also closely related to key intellectual...
A radioactive particulate release experiment to produce a near-field ground deposition representative of small-scale venting from an underground nuclear test was conducted to gather data in support of treaty capability development activities. For this experiment, aCO₂‐driven “air cannon” was used to inject ¹⁴⁰La, a radioisotope of lanthanum with 1.7‐d half-life...
Acid deposition and repeated biomass harvest have decreased
soil calcium (Ca) availability in many temperate forests worldwide, yet
existing methods for assessing available soil Ca do not fully characterize
soil Ca forms. To account for discrepancies in ecosystem Ca budgets, it
has been hypothesized that the highly insoluble biomineral Ca...

cultures.
The intent of this paper is to bring more attention to the mastery involved with film composition as an art form. The research focuses specifically on the life, style, influences, and works of John Williams as a conductor, film composer, and composer. It addresses his biography, filmography, and working relationships,...
The essays in this collection do not cluster about a specific theme, nor do they present a single unified interpretative approach to issues in the history of American foreign policy. Above all, William Appleman Williams is a teacher. And good teachers are disappointed with conformity. No one would ever come...
Traditional interpretations of James Joyce's Dubliners have often focused on the pervasive "paralysis" of the city, covered in the stories' range of "childhood, adolescence, maturity, and public life." However, these approaches have limited their focus on the women in the stories, often spotlighting the male characters--and the author--through a Freudian...
The major historical studies that have examined American
biology have emphasized the development of experimental biology at
the end of the nineteenth century. In this characterization, the
descriptive branch of biology has often been treated as less than
important and, in several cases, as a hindrance in the application
of...
The study of the question of why Shakespeare's Hamlet delays killing
Claudius in revenge for his father's murder is examined in light of the major
critical theories from neo-classical to modern scholarship. An expanded
treatment of the works of Fredson Bowers, Eleanor Prosser, Bertram Joseph,
and Roland Frye, is provided...
The Modern era, roughly the time between 1860-1930, brought about a significant restructuring of artistic mediums. From the canvas to the page, artists of the twentieth century turned towards collaboration as a means by which they could reconfigure their works. Painters, writers, and dancers, borrowed aesthetic techniques from one another...
Range, areas of concentrated activity, and dispersal characteristics for juvenile Steller sea lions Eumetopias jubatus in the endangered western population (west of 144° W in the Gulf of Alaska) are poorly understood. This study quantified space use by analyzing post-release telemetric tracking data from satellite transmitters externally attached to n...
In his works, A Portrait of the Artist as a Young Man (1916) and Ulysses
(1922), James Joyce demonstrates what he perceives to be the paralyzing effects of
those institutionalized religions that sit at the center of cultures. Drawing on Michel
Foucault's analysis of institutional dressage as well as his...
This is a set of documents and letters compromising a proposal by James McCauley to bring lobsters to the West Coast. The proposal involved the University of Rhode Island, the OSU Sea Grant Marine Advisory Program, Oregon State University, and the Oregon Fish Commission. The letters are to several people,...
Composition and structure of Oregon ash
(Fraxinus latifolia) woodlands in the William L. Finley
National Wildlife Refuge, Oregon are described. Twenty
stands dominated by Fraxinus latifolia were sampled with
500 m2 circular macroplots in which floristic microplot
data were collected for plant community synthesis. Plant
communities were identified by computer-assisted...
This study measures the recreational boating use in Prince William Sound, Alaska. Improved access conditions to the Sound over the last decade coupled with a statewide increase in outdoor recreation participation among both resident and out of state tourists have made the Sound a focal point for recreational boating in...
The present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...
Chum salmon from different stocks were bred together in two experiments. Three stocks contributed gametes to one experiment, two stocks to another. Sibling groups of eggs, alevins, and fry were maintained in a common environment. Variability of development rates, rearing performance, susceptibility to disease, and behavioral traits was partitioned into...
Studies were conducted during late winter and spring of 1970 to
establish the extent of spawning of Pacific herring (Clupea harengus
pallasi Valenciennes) in the Yaquina estuary, and to define the degree
of egg mortality on certain substrates. Routine surveillance of the
north shore of the estuary provided information on...
The examination in some detail of the relationships between
air quality and the thermal structure of the lowest layers of the atmosphere
constituted the primary objective of this thesis. Data for
the study were assembled during April-June 1965 at the U.S.
Weather Bureau Station, McNary Field, Salem, Oregon. The measures...
I experimentally test the hypothesis that the potential for selfing
increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible,
profusely-flowering perennial. This follows from the
premises that 1) pollen dispersal by pollinators between flowers is
limited, and 2) individual pollinators, in this study bumblebees, will
visit more flowers per...
Gothic literary works are characterized as such by their ability to represent and evoke terror. The form this representation takes is varied; often terror originates in the atmospheric effects of settings, in the appearance of mysterious, supposedly supernatural phenomena, and, perhaps most significantly, in the behavior of villainous characters. Shakespearean...
Ireland's Catholic Church played an important role in the turn-of-the-century nationalism that shaped James Joyce's identity and writing; yet it also played an important part in preventing that nationalism from achieving its goals of autonomy and cultural independence. For Joyce, this was particularly evident in the dialects and
thought structures...
Over recent decades, the marine ecosystems of Prince William Sound (PWS), Alaska have experienced the concurrent effects of a major anthropogenic disturbance, the 1989 Exxon Valdez oil spill (EVOS), and a dynamic atmospheric-oceanic environment. Studies of top marine consumers can provide insights into processes of ecosystem change. Using data collected...
Studies were conducted to determine the site of DCPA toxicity
on annual ryegrass. This was done by means of a technique which
used pyrex tubing and a vapor barrier to separate exposure of coleoptile
and roots of emerging grass seedlings to various concentrations of DCPA. Coleoptiles that emerged through treated...
Fume, sub-micron aerosal particles in the combustion gases, have been identified
as a cause of extensive plugging and fouling in the heat transfer section of a kraft
recovery boiler in kraft pulp mills. After the deposition on the heat transfer surface,
fume deposits will undergo the sintering process which causes...
The effects of possible operating variables such as flow rate, surface temperature, bulk temperature, solids contents, sulfate addition and pH on the fouling of sulfite spent evaporators were studied. The study pointed out that the Ca⁺⁺ concentration difference between heated surface and bulk is the most important factor for fouling...
Laminar entrained flow reactor (LEFR) was used to determine the effect of
temperature and residence time on the distribution of carbon, sulfur and nitrogen between
gaseous and condensed phase products from low temperature pyrolysis of kraft black
liquor. The operating furnace temperatures were between 400°C-600°C where the effect
of condensable...
Marine cyanobacteria have been shown to produce a variety of biologically active and stucturally diverse secondary metabolites. These compounds are of interest to natural products researchers mainly because of their potential application as biomedicinals, biochemical probes, and agrichemicals. The metabolic pathways utilized by the cyanobacterium Lyngbya majuscula to generate curacin...
A unique aspect of this study is that it involves an unusually
large number of individuals of American Indian descent. The sample
population was composed of those Indian members of the 1962 high
school graduating class from a six-state area. The selected graduates
came from local public, Bureau of Indian...
Seven commercially prepared brands of lactic streptococcal
phage inhibitory media were obtained from their manufacturers.
Comparisons between the different media were made with respect
to buffering capacity, ability to support lactic streptococcal growth,
ability to suppress bacteriophage replication, and ability to support
Leuconostoc growth. Nonfat milk was used during experiments...
Samples of commercial purity titanium were heat treated above the
beta transformation temperature and within the two phase alpha-beta
phase field, followed by cooling at varying rates. Testing of the
samples in tension and by instrumented impact indicated that some
strengthening could be imparted by these heat treatments, although at...
The public health and economic significance of rapid acid production
by lactic streptococci in controlled dairy fermentations is well
known. However, the fast acid-producing characteristic of these organisms
is not stable, and cultures of fast organisms have been shown
to contain slow cells. These studies were carried out to characterize...
In an effort to describe the plant communities and
succession of the Oregon coastal grasslands, vegetation
and environmental data were collected from 75 stands at
24 separate locations ranging from Cape Falcon in Tillamook
County to Cape Ferrelo in Curry County. The vegetation
data consisted of cover and frequency values...
