An Investigation Of Temporary Threshold Shift Among Helmeted Motorcycle Riders, Alamander Hicks

Dissertations and Theses

The purpose of the present study involved the investigation of the significance of wind noise as a contributing factor toward temporary threshold shifts among a select sample of motorcycle riders. Five normal-hearing, helmeted, female subjects were administered pure-tone air-conduction hearing tests immediately before and within 2 minutes after exposure to three noise-related aspects of motorcycle riding. The amount of hearing loss present at 3k, 4k and 6k Hz after each 20 minute exposure condition was recorded as the TTS for that subject. The three conditions consisted of motorcycle noise only, wind noise only and motorcycle and wind noise combined. A …

Moment-Curvature-Thrust Relationships In Hybrid Members, Douglas Wrenn Fiala

Dissertations and Theses

In order to overcome the difficulties encountered in closed form solutions, moment-curvature-thrust relationships are developed for hybrid and nonhybrid cross sections utilizing an open form method. The use of horizontal sectors permits the inclusion of residual stresses and/or nonbilinear stress-strain relationships, if desired. Theoretical and experimental data are compared. Applications to circular tubes and other cross sections are discussed. Results indicate that open form solutions are feasible for calculating moment-curvature-thrust data. Hybrid cross sections are easily treated by open form solutions.

Mutual Exclusion Between Salmonberry And Douglas-Fir In The Coast Range Of Oregon, Kenneth Ray Still

Dissertations and Theses

One serious problem faced by the forest industry in the Pacific Northwest is poor regeneration of commercial trees on land which is harvested and subsequently dominated by brush species. In Coastal Oregon, salmonberry is one of these brush species. Detailed investigations of field sites indicate that light intensity in the brush stands was low but sufficient for germination and early growth of Douglas-fir seedlings and soil moisture percentages and nutrient levels were high enough to support early Douglas-fir growth. Laboratory tests demonstrated the presence of leachable phytotoxins in the leaves of salmonberry. The hypothesis resulting from this study is that …

This study is based on a sample of women seeking pregnancy counseling at Planned Parenthood in Portland in the calendar year 1971. During that year about 1,230 …

A Study Of The Characteristics Of Runaways And Their Families In Two Social Agencies, Susan G. Greer, Sarah J. Hertlein, Stephen C. Regner

Dissertations and Theses

Because of the relative uniqueness of the runaway experience as it now exists, minimal current research information is available. It was our feeling that knowledge about runaways, their families, and the social agencies which serve them is essential if significant prevention and treatment for the problem were to be implemented by the community. The purpose and scope of this exploratory research was essentially two-fold; to contribute descriptive information about runaway youth and their families to the community, and to evaluate the current populations of two agencies which service them. An underlying goal throughout the research was to utilize the data …

A Functional Interpretation Of Pottery From Batan Island, Philippines, Joanne M. Laetsch

Dissertations and Theses

This thesis is a report on a pottery analysis which was carried out in the laboratory of the Department of Anthropology at Portland State University. The earthenware materials involved were collected from three surface sites on Batan Island, Philippines, during the summer of 1969.

The interpretation of these potteries was based upon the direct-historical approach to archaeological research. The use of this method was proposed after a cursory examination of the earthenwares revealed certain general similarities between the archaeological potteries and the ethnographically-known wares produced in the area at the present time. One of the sites was a known habitation, …

The Life Cycle Of Lissorchis Heterorchis, Macy And Krygier (1969), Brendan P. H. Onyejekwe

Dissertations and Theses

Many Flumenicola virens (Lea) collected from Crystal Springs Creek and Tualatin River, Portland, Oregon, were found to shed large numbers of a species of microcercous cercariae containing refractile granules. They resembled the cercariae of Triganodistomum mutabile (=Lissorchis mutabile Cort, 1918 as described by Wallace (1939), and subsequent experiments proved that they were the larval stages of what was described by Macy and Krygier (1969), as Lissorchis heterorchis. Encystment of these cercariae was induced experimentally in uninfected adult brown planarians collected partly from Crystal Springs Creek and partly from Carolina Biological Research Station in Gladstone, Portland, Oregon.

Application Of Numerical Analysis To Root Locus Design Of Feedback Control Systems, Steve William Justice

Dissertations and Theses

Many practical problems in the field of engineering become so complex that they may be effectively solved only with the aid of a computer. An effective solution depends on the use of an efficient algorithm. Plotting root locus diagrams is such a problem. This thesis presents such an algorithm.

Root locus design of feedback control systems is a very powerful tool. Stability of systems under the influence of variables can be easily determined from the root locus diagram. For even moderately complex systems of the type found in practical applications, determination of the locus is extremely difficult if accuracy is …

Catechol Effected Dissolution Of Silicate Minerals, James Maurice Kelley

Dissertations and Theses

The chemical properties of guanidinium tris(catecholato)siliconate, [(H₂N)₂C=NH₂]₂[Si(C₆H₄O₂)₃]·XH₂O (0 < X < 1), precipitated from an ammoniacal solution of silica and catechol by adding guanidinium hydrochloride, (H₂N)₂C=NH·HC1, were studied, and infrared, nmr, x-ray powder diffraction, and analytical data were gathered.

This same compound was, upon addition of' (H₂N)₂C=NH·HC1, isolated from 0.25, M aqueous catechol solutions buffered at pH 10 and containing the silicate minerals albite, andradite, muscovite, pyrophyllite, talc, and wollastonite, and also from unbuffered catechol solutions containing wollastonite and andradite.

It is concluded from this work that the formation of an anionic catechol-silicon complex, Si(C₆H₄O₂)₃²⁻, is largely responsible for the dissolution of the minerals mentioned above. From this conclusion, it is proposed that naturally occurring members of the class of organic compounds to which catechol belongs, the aromatic v̲i̲̲c̲-diols, may play …

Children Without Futures: A Feasibility Study Comparing Characteristics Of Families Who Have Children Placed In Long And Short-Term Foster Care, Kaye Hutchins

Dissertations and Theses

Many children drift into unplanned long-term foster home care, under conditions unsatisfactory for the child, his own family and the foster parents. Current practice in foster care often contributes to foster children growing up without the necessary love, support and guidance from a family that he can call his own. Recent publications in social work journals have suggested that a lack of consistent family relationships may be injurious to the emotional development of children. Social workers have become increasingly dissatisfied with a "helping process" that may, in fact, generate more harm than help. Originating from the social worker's dissatisfaction with …
