Americium and plutonium in water, biota, and sediment from the central Oregon coast

Description: Plutonium-239, 240 and americium-241 were measured in the mussel Mytilus californianus from the region of Coos Bay, OR. The flesh of this species has a plutonium concentration of about 90 fCi/kg, and an Am-241/Pu-239, 240 ratio that is high relative to mixed fallout, ranging between two and three. Transuranic concentrations in sediment, unfiltered water, and filterable particulates were also measured; none of these materials has an Am/Pu ratio as greatly elevated as the mussels, and there is no… more

Parametrization of net radiation at the surface using data from the Wangara experiment

Description: Hourly Wangara boundary layer data (Clark et al., 1971) was used to substantiate previously derived empirical equations of the surface radiation budget. These equations only require measurements taken by a surface observer in order to be evaluated. A parameterization was made for infrared (IR) radiation. From this procedure, a residual radiation was obtained from the measured daytime net radiation data in order to approximate short wave (SW) radiation. Diurnal trends in radiation and other rela… more

Selected Factors Associated With Reading Interests of Seventh- and Eighth-grade Pupils

Description: This study sought to determine if there were differences in the types of reading interests of seventh- and eighth-grade pupils associated with their racial origins, their socioeconomic status, or their school environments. It also sought to consider the strength of reading interest scores as related to other variables and to consider the relationship between these scores and the number of hours spent in reading and the change in amount of reading since the previous school year.

The Extensive Subject File a Study of User Expectations in a Theological Library

Description: This study is concerned with determining how library patrons decide which entries to select from a subject card file which consists of numerous bibliographic records. Patrons are expected to select certain records based on elements that are objective (displayed directly by the record and requiring little or no interpretation) or subjective (recognized because of the user's special knowledge of the field).

Empirical Research of Decision-making Effectiveness When Using Differing Presentation Formats Under Varying Decision Tasks

Description: The purpose of this research was to determine if presentation format, given a particular task to be performed, would affect the decision-making process of financial decision makers. The problem motivating this study is the potential for managers to make inefficient decisions when they use reports which are presented inappropriately for a given task.

Vaporization of synthetic fuels. Final report.

Description: The problem of transient droplet vaporization in a hot convective environment is examined. The main objective of the present study is to develop an algorithm for the droplet vaporization which is simple enough to be feasibly incorporated into a complete spray combustion analysis and yet will also account for the important physics such as liquid-phase internal circulation, unsteady droplet heating and axisymmetric gas-phase convection. A simplified liquid-phase model has been obtained based on t… more

Mass-spectrometric determination of trace elements in aqueous media without preconcentration

Description: Feasibility of using a low pressure glow discharge as an ion source for the mass spectrometric determination of trace elements in aqueous media was investigated. A cryogenically cooled hollow cathode ion source was developed to analyze aqueous samples without external preconcentration. Aqueous solutions containing seventy elements were analyzed and the detection limits, sensitivity factors, and linear regression correlation coefficients were determined. A standard test solution of trace element… more

An Investigation of the Whistle Register in the Female Voice

Description: The purpose of the study was concerned with specific elements of the portion of the female voice commonly referred to as whistle or flute register. Three elements of vocal production were chosen for which past research has demonstrated relationships to source function. These elements included spectral characteristics, airflow rates, and perceptual identification. The research compared what the singer-subjects perceived as being whistle register phonations with that which they perceived as being… more

Programming Generalization: A Comparison of Behavioral and Cognitive Response Transfer Operations in Assertive Training

Description: The assertive training literature has documented the effectiveness of both behavioral and cognitive methods to increase individual's assertiveness. However, the ability for such methods to enhance the generalization of treatment effects to untrained assertive response classes and the natural environment has been poor. In addition, little notice has been paid to the durability of these changes. Although the past several years have witnessed more intensive efforts by investigators to program gene… more

Description: Zvklus (1959) by Karlheinz Stockhausen and Duettino Concertante (1966) by Ingolf Dahl represent two of the most significant percussion compositions that present the percussionist as soloist. The performer of these works, either unaccompanied or accompanied by a non-percussion instrument, is featured as executant, interpreter, and improvisor. They are regarded as classics in the medium of multiple percussion because of their frequency of performance and their profound effect on notation, musical… more

First Impressions of Therapists: the Effect of Therapist Gender, Gaze, Smiling and Subject Gender

Description: Conceptualization psychotherapy as an interpersonal influence process emphasizes how a therapist is perceived by a client. Factors affecting a client's early impressions of a therapist could influence therapeutic interactions since first impressions are relatively stable. The study investigated effects of nonverbal behavior and gender during a simulated initial meeting between a therapist and client. Undergraduates (N = 466) viewed a male or female therapist interviewing with a new female clien… more
