Dans ce travail, nous avons développé un système expert qui intègre les fonctions suivantes :i) l'identification des profils à partir des mesures sur les plasmas de tokamak, par les méthodes bayésiennes; ii) La prédiction des quantités reconstruites, selon les modèles choisis et; iii) une comparaison intelligente des résultats provenant des deux premières étapes. Ce système comprend une vérification systématique de la cohérence interne des quantités reconstruites, permet la validation automatique des modèles. Avec un modèle validé, il peut aider à la détection de nouveaux effets physique dans une expérience. Trois applications de ce système sont présentées dans ce travail. Le système expert peut détecter automatiquement les défauts dans la reconstruction des profils et fournir (lorsque la reconstruction est valide) des statistiques sur l'accord des modèles avec les données expérimentales, c'est à dire des informations sur la validité du modèle. / In this work we developed an expert system that carries out in an integrated and fully automated way i) a reconstruction of plasma profiles from the measurements, using Bayesian analysis ii) a prediction of the reconstructed quantities, according to some models and iii) an intelligent comparison of the first two steps. This system includes systematic checking of the internal consistency of the reconstructed quantities, enables automated model validation and, if a well-validated model is used, can be applied to help detecting interesting new physics in an experiment. The work shows three applications of this quite general system. The expert system can successfully detect failures in the automated plasma reconstruction and provide (on successful reconstruction cases) statistics of agreement of the models with the experimental data, i.e. information on the model validity.

Detta projekt handlar om en övergång till högre stålhållfasthet. Övergången sker från stålhållfastheten S355 till S690 i HEA-profiler för pelare samt vindbockar. Valet att genomföra detta projekt kommer ifrån att det skulle vara intressant att se om det finns några vinster med att övergå till högre stålhållfasthet. Under projektets gång kunde det konstateras att mindre stålprofiler kunde väljas vid val av S690 istället för den traditionella S355. För just denna specifika stålhall som undersöktes minskades pelarstorleken med tre pelarprofiler. Medan för vindbockarna kunde endast en pelarprofil minskas. Vid användning av stålhållfastheten S690 uppnås tvärsnittklass 4 för ett fåtal HEA-profiler. Detta medför till mer omfattande dimensioneringsutförande jämfört med stålhållfastheten S355 som endast når tvärsnittsklass 3 som högst. Det föreligger för tillfället ett ekonomiskt incitament för att välja högre stålhållfasthet enligt de approximerade kostnadsanalyser som verkställdes under projektets gång. Med den högre stålhållfastheten blir stålmängden lägre för stålhallen. Detta medför mindre transporter till byggarbetsplatsen, vilket är gynnsamt både ur ett miljöperspektiv och ekonomiskt perspektiv. / This project is about a transition to higher steel strength. The transition is from steel strength S355 to S690 in HEA- profiles for column and wind trestles. The choice to do this project comes from the fact that it would be interesting to see if there are any profits in switching to higher steel strength. During the project process it was found that smaller steel profiles could be chosen when S690 was selected instead of the traditional S355. For this particular steel hall the column size was reduced by three column profiles and for the wind trestles only one profile could be reduced. When the steel strength S690 is used, the cross class 4 is obtained for a few HEA- profiles. This leads to more extensive dimensioning performance compared to the steel strength S355 which reaches only the cross class 3 as the highest. At present there is an financial incentive to choose higher steel strength according to the approximate cost analyzes carried out during the project process. With the higher steel strength, the steel amount becomes lower for the steel hall. This leads to less transport to the construction site. Which is beneficial both for an environmental perspective and economic perspective.

Master of Science / Department of Agronomy / Gary M. Pierzynski / Soil chemical and physical properties beneath cattle feedlot pens are largely unstudied. This project was conducted to survey select soil chemical and physical properties of soil beneath active open air cattle feedlots. At four cattle feedlots in Kansas, the concentrations of NH4-N, organic-N, organic-C, Cl-, and P were high at the surface and rapidly decreased within 1.00 m. At three of the four feedlots, NO3-N was generally below background concentration (4.1 mg kg-1) while one feedlot had a >75 mg kg-1 increase in the top 1.00 m. Based on feeding data, only a small percent (7.9 to 1.2) of the total N deposited on the surface was found in the top 1.00 m below the pen surface for a range of 25 to 60 years of operation. While in use, these feedlots do not appear to have a high potential for groundwater pollution from NO3-N leaching. However, if they were to become inactive they may pose a severe threat to groundwater quality from organic-N mineralization and NH4-N nitrification. If feedlots were closed and the land could be largely remediated by removing a layer of soil, these feedlots would have an average 48% profile N removed in a 0.25 m thick layer. A chamber, a modified vacuum desiccator, was tested for the investigation of NH3 volatilization from soil in the laboratory. Ammonia volatilization at the soil surface is dependent on air flow, soil and air temperatures, soil water content, pH, the concentrations of NH3 and NH4+ in the air and soil solution, and factors affecting soil temperature including humidity. This chamber was built to control and/or quantify as many of these variables as possible. A technique for quantifying and predicting NH3 volatilization is important because AFOs are one of the largest contributors of NH3 to the atmosphere, which can cause acid precipitation and particulate matter deposition downwind from the operation. The chambers created allowed for repeated measurements with little error and appear to be a feasible, inexpensive apparatus to investigate NH3 volatilization mechanisms. Using synthetic urine as an N source, NH3 volatilization was affected by initial soil moisture content and soil texture and may be affected by initial soil pH. This chamber has promise to provide excellent data to assist the efforts being made to understand and model NH3 volatilization from feedlot pens.

This study was prompted by the need the author experienced for the rethinking of many practices in music teaching and her interest in achieving transformation in individual music teaching and learning. An eclectic approach was adopted for the research. Despite much existing ‘fuzzy’ terminology, ‘broader’ or ‘less fixed’ meanings were sought of terms including Holism, intelligence, learning, Modernism, perception, personality, Postmodernism, teaching, temperament and whole-brain learning. The reader is presented with a palette of ideas, open for further exploration, in order to stimulate creativity and different viewpoints in music teaching and learning. The study has a student-centred approach, taking into account different types of learners and how to adapt teaching styles to connect with students in their learning environment. Challenges teachers may encounter are how the meanings of many terms relate with music teaching practice, themselves and their pupils. The research explores the interaction and relation of terms with one another in order to reconsider and expand teaching methods. Inter, intra and multidisciplinary aspects of teaching are touched upon as being valuable in cutting across several traditional fields of study and also referring to knowledge seen as a coherent whole within one subject area. Experiences of ‘flow’ and transformative learning are explored in order to challenge students’ and teachers’ ‘fixed’ thinking methods. The whole-brain model is considered where the brain is seen in four quadrants, each quadrant displaying distinctive strengths of value in music teaching. The importance of Emotional Intelligence in developing other intelligences is investigated and its link with Inter and Intrapersonal Intelligences in order to equip teachers to connect effectively with pupils in a learning context. There is no “one size fits all” teaching strategy, learning style or framework that can apply to the myriad needs of individual music teachers and pupils. The research, however, demonstrates the importance for music teachers to be receptive in enlarging their thinking patterns. In so doing a path can be set for shifting focus in teaching strategies to a ‘moving forward’ ideal in perception and understanding of teaching and learning in the 21st century. / Thesis (DMus)--University of Pretoria, 2010. / Music / unrestricted

This research was designed to determine if significant differences exist among the behavioral perceptions and values held by staff and user groups of all junior high schools in a selected independent school district. This study also evaluates the applicability of social profiles to describe perceived organizational behavioral characteristics. Two published, validated survey instruments were used to collect the data. The questionnaires were distributed to randomly selected teachers (staff group) and parents and Parent-Teacher Association officers (user group) from each of the five junior high schools. Of 206 sets of questionnaires distributed, 166 (80.5 percent were returned. Computer analyses of these raw data provided both individual perceptions and descriptions for each junior high school in addition to individual values for each school's staff and user group. The data results show that the social profiles of two of the five schools are perceived differently by both their staff and user groups; furthermore, there are significant differences between the values held by the staff and user groups for each of these schools. For the other three schools, there are minor differences of perception by staff and user groups of their schools' social profiles and also among the values held by the staff and user groups. The data analysis presented in this study led to three primary conclusions. These are that (1) the instruments used complement each other in an analysis of the overall description of an organization; (2) three schools, although perceived by their staff and user groups to have minor differences in behaviors and user-group values held, are similar in organizational characteristics, methods of operation, and overall perceptions; and (3) for two of the schools which are perceived to reflect significant differences in behaviors and values held by staff and user groups, the influence of these differences may require exceptionally proficient administration to produce effectiveness and efficient operations.

The purpose of this study is to analyze the relationships between stress and outcomes including organizational citizenship behavior (OCB), job satisfaction, and burnout in high-risk occupations. Moreover, how personality, emotions, coping, and leadership influence this relationship is investigated. Data were collected from 379 officers in 9 police organizations located in the Southern and Southwest United States. The primary research question addressed within this dissertation is: What is the relationship between stress and behavioral and affective outcomes in high-risk occupations as governed by coping, leadership, and crisis? The majority of the hypothesized relationships were supported, and inconsistencies center on methodological and theoretical factors. Findings indicate that occupational stressors negatively influence individuals in high-risk occupations. Moreover, crisis events exacerbate these influences. The use of adaptive coping strategies is most effective under conditions of low stress, but less so under highly stressful circumstances. Similarly, transformational leader behaviors most effectively influence how individuals in high-risk occupations are affected by lower, but not higher levels of stress. Profiles of personality characteristics and levels of emotional dissonance also influence the chosen coping strategies of those working in high-risk occupations. Prescriptively, it is important to understand the influences among the variables assessed in this study, because negative outcomes in high-risk occupations are potentially more harmful to workers and more costly to organizations. Thus, this dissertation answers the research question, but much work in this area remains to be done.

The aim of this paper is to analyze Sergipe´s intellectual formation during the empire period as well as to prove that the origin of that intellectuality was in that period and not in the republic. For that, it was observed the sending of Sergipanos students by the Province elite to educational Brazilian centers as well as European centers between 1822 and 1889. That time marks Sergipe´s identity as well as the national identity and also their performance as intellectuals in Sergipe, contributing, this way, to build up Sergipe´s intellectual profiles. To deeply analyze this intellectuality, it has been selected 400 (four hundred) names which have been recognized and legitimated by Sergipe´s society as intellectuals. / Este trabalho tem como objetivo analisar a formação da intelectualidade sergipana durante o Império, objetivando comprovar que ela se originou no período imperial e não no republicano. Para tanto, foi estudado o envio de estudantes sergipanos aos centros educacionais brasileiros e a europeus, pela elite da Província, durante o período de 1822 a 1889, época que marca a formação de uma identidade sergipana e nacional e sua atuação como intelectuais em Sergipe, construindo assim o campo intelectual sergipano. Para análise da formação dessa intelectualidade, foram selecionados quatrocentos (400) nomes reconhecidos e legitimados pela sociedade sergipana como intelectuais.

The purpose of the present study was to begin development of a psychological profile for environmentally ill patients. Existing psychiatric labels are unable to encompass these patients. Test scores were drawn from a pool of 89 patients whose environmental exposures were verified by the presence of toxins in the blood serum. A Mental Status Exam, a Wechsler Adult Intelligence Scale-Revised screen, and the Profile of Mood States were administered. Results indicate a primary pattern which is significantly different from test norms consisting of fatigue, reduced mental functioning, and a lack of psychotic or personality disorder indicators. The reported symptoms of environmentally ill patients were objectively verified by current psychological test instruments. The need for a new diagnostic category for people who have been poisoned by environmental toxins is discussed.

Recent genomic data indicate that RNA polymerase II (Pol II) function extends beyond conventional transcription of primarily protein-coding genes. Among the five snRNAs required for pre-mRNA splicing, only the U6 snRNA is synthesized by RNA polymerase III (Pol III). Here we address the question of how Pol II coordinates the expression of spliceosome components, including U6. We used chromatin immunoprecipitation (ChIP) and high-resolution mapping by PCR to localize both Pol II and Pol III to snRNA gene regions. We report the surprising finding that Pol II is highly concentrated ∼300 bp upstream of all five active human U6 genes in vivo. The U6 snRNA, an essential component of the spliceosome, is synthesized by Pol III, whereas all other spliceosomal snRNAs are Pol II transcripts. Accordingly, U6 transcripts were terminated in a Pol III-specific manner, and Pol III localized to the transcribed gene regions. However, synthesis of both U6 and U2 snRNAs was α-amanitin-sensitive, indicating a requirement for Pol II activity in the expression of both snRNAs. Moreover, both Pol II and histone tail acetylation marks were lost from U6 promoters upon α-amanitin treatment. The results indicate that Pol II is concentrated at specific genomic regions from which it can regulate Pol III activity by a general mechanism. Consequently, Pol II coordinates expression of all RNA and protein components of the spliceosome.
