1990 yearly calibration of Pacific Northwest Laboratory's gross-gamma borehole geophysical logging system
This report describes the 1990 yearly calibration of a gross-gamma geophysical pulse logging system owned by the US Department of Energy (DOE) and operated by Pacific Northwest Laboratory (PNL). The calibration was conducted to permit the continued use of this system for geological and hydrologic studies associated with remedial investigation at the Hanford Site. Primary calibrations to equivalent uranium units were conducted in borehole model standards that were recently moved to the Hanford Site from the DOE field calibration facility in Spokane, Washington. The calibrations were performed in borehole models SBL/SBH and SBA/SBB, which contain low equivalent-uranium concentrations. The integrity of the system throughout the previous year from gamma-ray monitoring was demonstrated using the before- and after-logging field calibration readings with the field source in calibration Positions 1 and 2. Most of the Position 1 readings are within an 8% limit that is set by the governing PNL technical reference procedure as a critical value above which the instrument is considered suspect. Many of the Position 2 readings exceed the 8% limit; however, the fluctuation was traced to field-source geometry variability that affected Position 1 count rates by up to 6% and Position 2 count rates by as much as …

Academic Achievement Among Language-Impaired Children as a Function of Intensive Preschool Language Intervention
Parents and professionals are concerned about the long-term effects of language problems on later academic, communicative and behavioral functioning of children. The purpose of this study was to examine the relationship of level of language impairment with type of class placement, reading achievement, and social emotional functioning. Subjects were 19 children, aged 4 years, 10 months through 10 years, 4 months, who had previously been enrolled in a preschool language development program. Statistical analyses were performed on data from the Kaufman Assessment Battery for Children (K-ABC), Test of Early Reading Ability (TERA), and the Achenbach Child Behavior Checklist (CBC). Results do not support a relationship between level of language impairment and academic or social/emotional functioning.

Academic Achievement of National Social Fraternity Pledges Compared to Non-Fraternity Students
This study examined the academic achievement of national social fraternity pledges compared to non-fraternity students at the University of Texas at Arlington. It was done to determine whether significant differences existed between the grade point averages of pledges of social fraternities and those of students who did not pledge a social fraternity, and to determine whether significant differences existed among fraternities when compared with each other with respect to academic achievement. This study was meant to provide a research design that could be used by other colleges and universities with fraternities to conduct the same comparison of academic performance. In the fall semester of 1989, 164 pledges were selected as the population for the study to be matched with non-fraternity students based on Scholastic Aptitude Test (SAT) scores, age, sex, classification, academic major, and number of hours attempted. A T-test of like groups was performed on the entire population with no significant difference found at the .05 level between all the fraternity pledges and all the matched pairs. A T-test of like groups was performed on the pledges from each separate organization and there was a significant difference among three of the fraternities. Two of the fraternities had significantly higher …

Academic, Behavioral, and Social Competency Characteristics of Non-Handicapped, Learning Disabled, and Emotionally/Behaviorally Disordered Adjudicated Juveniles
The juvenile justice system is society's response to juvenile misconduct. In spite of numerous federal, state, and local programs, the problem of juvenile delinquency persists. An increasing number of juveniles are being taken into custody and placed in institutional settings. Although juvenile delinquents share a number of common general characteristics (e.g., sex, minority, lower socioeconomic status, a history of school failure), they are not a homogeneous group. Effective educational interventions with delinquent juveniles can meet their unique academic, vocational, and social skills deficits. Handicapped juveniles are disproportionately represented among juvenile correctional facility populations. The identification of handicapped juveniles among delinquent populations is compounded as they share many of the same general characteristics. Federal statutes require individualized educational programs for all handicapped juveniles. This research investigated academic, behavioral, and social competencies of non-handicapped and handicapped adjudicated youth. Specifically, this investigation assessed measures of academic performance, classroom behavior, self-esteem, and social behavior. ANOVA indicated statistically significant differences between non-handicapped, learning disabled, and emotionally/behaviorally disordered adjudicated juveniles in reading achievement, mathematics achievement, and teacher generated measures of classroom behavior.

The Advanced Light Source at the Lawrence Berkeley Laboratory (ALS, LBL)
The Advanced Light Source (ALS), a national facility currently under construction at the Lawrence Berkeley Laboratory (LBL), is a third-generation synchrotron light source designed to produce extremely bright beams of synchrotron radiation, in the energy range from a few eV to 10 keV. The design is based on a 1-1.9 GeV electron storage ring (optimized at 1.5 GeV), and utilizes special magnets, known as undulators and wigglers (collectively referred to as insertion devices), to generate the radiation. In this paper we describe the main accelerator components of the ALS, the variety of insertion devices, the radiation spectra expected from these devices, and the complement of experiments that have been approved for initial operation, starting in April 1993.

Advanced Neutron Source equipment data base. [Advanced Neutron Source Facility]
The Advanced Neutron Source (ANS) is a new experimental facility planned to meet the national need for an intense, steady-state source of neutrons. It will be open for use by scientists from universities, industry, and other federal laboratories. The ANS will be equipped with an initial complement of advanced instruments for neutron scattering and nuclear physics research, with facilities for isotope production and for the study of materials in high radiation fields. The central structure is a 60-m ({approximately}200-ft) diam cylindrical, domed reactor building. This building will house the reactor itself, with its lower floors dedicated to beam and irradiation experiments and with a high-bay floor dedicated to reactor operations. A reactor support building, to be adjacent to the reactor building, will house other large reactor equipment and the general support equipment not located in the reactor building. The primary heat exchanger and circulating pumps will be located in cell banks within reactor containment. The guide hall building, connected to the reactor dome outside reactor containment, is dedicated to beam experiment use. The fourth building will be an office building serving both the extensive user community and the reactor operations staff. These buildings will contain many of the systems needed …

Advanced systems for producing superclean coal
The purpose of this project was to develop several advanced separation processes for producing superclean coal containing 0.4--2.0% ash and very little pyritic sulfur. Three physical and physico-chemical processes were studied: microbubble flotation, selective hydrophobic coagulation, and electrochemical coal cleaning. Information has been collected from bench-scale experiments in order to determine the basic mechanisms of all three processes. Additionally, because microbubble flotation has already been proven on a bench scale, preliminary scale-up models have been developed for this process. A fundamental study of the electrochemistry of coal pyrite has also been conducted in conjunction with this scale-up effort in order to provide information useful for improving sulfur rejection. The effects of additives (NaCl and kerosene) were also investigated. 94 refs., 167 figs., 25 tabs.

Advising the ARVN: Lieutenant General Samuel T. Williams in Vietnam, 1955-1960
Beginning in 1954, the United States Army attempted to build a viable armed force in South Vietnam. Until the early 1960s, other areas commanded more American attention, yet this formative period was influential in later United States involvement in Vietnam. This thesis examines United States advisory efforts from 1955 to 1960 by analyzing the tenure of Lieutenant General Samuel T. Williams as Chief of the Military Assistance Advisory Group in South Vietnam. During Williams's tenure, the communist forces in the north began the guerrilla insurgency in earnest. Williams's failure to respond to this change has been justly criticized; yet his actions were reflective of the United States Army's attitude toward insurgencies in the late 1950s.

Aging evaluation of class 1E batteries: Seismic testing
This report presents the results of a seismic testing program on naturally aged class 1E batteries obtained from a nuclear plant. The testing program is a Phase 2 activity resulting from a Phase 1 aging evaluation of class 1E batteries in safety systems of nuclear power plants, performed previously as a part of the US Nuclear Regulatory Commission's Nuclear Plant Aging Research Program and reported in NUREG/CR-4457. The primary purpose of the program was to evaluate the seismic ruggedness of naturally aged batteries to determine if aged batteries could have adequate electrical capacity, as determined by tests recommended by IEEE Standards, and yet have inadequate seismic ruggedness to provide needed electrical power during and after a safe shutdown earthquake (SSE) event. A secondary purpose of the program was to evaluate selected advanced surveillance methods to determine if they were likely to be more sensitive to the aging degradation that reduces seismic ruggedness. The program used twelve batteries naturally aged to about 14 years of age in a nuclear facility and tested them at four different seismic levels representative of the levels of possible earthquakes specified for nuclear plants in the United States. Seismic testing of the batteries did not cause …

Aldo Rossi: From Modern to Post-Modern Architecture, 1960-1990
The purpose of this thesis is to discuss the stylistic development of the Italian architect Aldo Rossi from Modern to Post-Modern design. A summary of the Modern architectural movement is presented along with an analysis of the developments in Post-Modern architecture since 1960. The influence of Italian culture on Rossi's career is discussed through a brief survey of Ancient Roman archetypal motifs and Italian architecture of the early 20th century. Several key buildings proposed or constructed by Rossi from 1960-1990 are discussed based on his concepts of analogy, typology, morphology and rationalism.

Alternative configurations for the waste-handling building at the Yucca Mountain Repository
Two alternative configurations of the waste-handling building have been developed for the proposed nuclear waste repository in tuff at Yucca Mountain, Nevada. One configuration is based on criteria and assumptions used in Case 2 (no monitored retrievable storage facility, no consolidation), and the other configuration is based on criteria and assumptions used in Case 5 (consolidation at the monitored retrievable storage facility) of the Monitored Retrievable Storage System Study for the Repository. Desirable waste-handling design concepts have been selected and are included in these configurations. For each configuration, general arrangement drawings, plot plans, block flow diagrams, and timeline diagrams are prepared.

Alzheimer's Disease and Attention: An Investigation into the Initial Stage of Information Processing
This study explores the possibility that attentional deficits are an early clinical symptom of Alzheimer's disease. The three goals are to demonstrate that individuals with Alzheimer's disease are impaired on tasks of attentional processing, to compare the sensitivity of currently used measures of attention to attentional dysfunction, and to compare the behavioral response styles (errors of commission) of Alzheimer's disease subjects and non-impaired subjects. The subjects were 22 males and 46 females with a mean age of 70.76 years. Thirty-six had the presumptive diagnosis of Alzheimer's disease; 18 were identified as mildly impaired and 18 as moderately impaired on the Cognitive Capacity Screening Examination. The remaining 32 subjects comprised the non-impaired control group. Five measures of attention were administered to all participants: the Digit Span Subtest of the WAIS-R, the Seashore Rhythm Test of the Halstead-Reitan Neuropsychological Battery, the Vigilance and Distractibility tasks of the Gordon Diagnostic System, and the Concentration/Interference task. The results show a significant difference in attentional processing between normal (non-impaired) subjects and subjects diagnosed with Alzheimer's disease. All measures of attention used in this study, except the Concentration/Interference task, differentiated normal subjects from moderately impaired Alzheimer's disease subjects. The Digit Span Subtest and the Seashore Rhythm …

Analysis of a Human Transfer RNA Gene Cluster and Characterization of the Transcription Unit and Two Processed Pseudogenes of Chimpanzee Triosephosphate Isomerase
An 18.5-kb human DNA segment was selected from a human XCharon-4A library by hybridization to mammalian valine tRNAiAc and found to encompass a cluster of three tRNA genes. Two valine tRNA genes with anticodons of AAC and CAC, encoding the major and minor cytoplasmic valine tRNA isoacceptors, respectively, and a lysine tRNAcuu gene were identified by Southern blot hybridization and DNA sequence analysis of a 7.1-kb region of the human DNA insert. At least nine Alu family members were found interspersed throughout the human DNA fragment. The tRNA genes are accurately transcribed by RNA polymerase III in a HeLa cell extract, since the RNase Ti fingerprints of the mature-sized tRNA transcription products are consistent with the DNA sequences of the structural genes. Three members of the chimpanzee triosephosphate isomerase (TPI) gene family, the functional transcription unit and two processed pseudogenes, were characterized by genomic blotting and DNA sequence analysis. The bona fide TPI gene spans 3.5 kb with seven exons and six introns, and is the first complete hominoid TPI gene sequenced. The gene exhibits a very high identity with the human and rhesus TPI genes. In particular, the polypeptides of 248 amino acids encoded by the chimpanzee and human …

An Analysis of Dominick Argento's "Peter Quince at the Clavier": the Music and Its Relationship to the Text
Dominick Argento (b. 1927) occupies an important position among American composers. This thesis discusses his 1980 choral work Peter Quince at the Clavier: Sonatina for Mixed Chorus and Piano Concertante. On the surface, the choral and piano parts of this four movement work often sound dissimilar. To create unity within this composition, Argento utilizes a small number of generative elements that govern the pitch, intervallic, and rhythmic dimensions of the composition. This thesis also discusses the relationship between the music and the text, a poem by Wallace Stevens (1879-1955).

Analysis of health impact inputs to the US Department of Energy's risk information system
The US Department of Energy (DOE) is in the process of completing a survey of environmental problems, referred to as the Environmental Survey, at their facilities across the country. The DOE Risk Information System (RIS) is being used to prioritize these environmental problems identified in the Environmental Survey's findings. This report contains a discussion of site-specific public health risk parameters and the rationale for their inclusion in the RIS. These parameters are based on computed potential impacts obtained with the Multimedia Environmental Pollutant Assessment System (MEPAS). MEPAS is a computer-based methodology for evaluating the potential exposures resulting from multimedia environmental transport of hazardous materials. This report has three related objectives: document the role of MEPAS in the RIS framework, report the results of the analysis of alternative risk parameters that led to the current RIS risk parameters, and describe analysis of uncertainties in the risk-related parameters. 20 refs., 17 figs., 10 tabs.

Analysis of offsite Emergency Planning Zones (EPZs) for the Rocky Flats Plant. [Contains glossary]
A quality assurance plan (QAP) is a documented description or a listing of the controls to be implemented to assure that an operation or activity is accomplished in a consistent manner and in accordance with requirements. Federal, state, and local governments require emergency planning for facilities that may affect the public in the event of an accidental release of nuclear or hazardous materials. One of the purposes of this EG G Rocky Flats Plant (RFP) Analysis of Offsite Emergency Planning Zones (EPZ) project is to identify the EPZs where actions could be necessary to protect public health. The RFP EPZ project is developing an interim basis for potential sheltering and evacuation recommendations in the event of an accidental release of radionuclides to the atmosphere from this facility. Also, RFP is developing EPZs for accidental releases of major nonradiological hazardous substances to the atmosphere, and will analyze the impacts of an unplanned surface water release from the facility.
