Includes bibliographical references (p. 70-71).
Reducing energy consumption without compromising the quality of products and the comfort of occupants is important in maintaining the competence of a pharmaceutical company. An energy management tool is developed to monitor the energy efficiency and calculate the cooling load. After analyzing the Energy Utilization Index (EUI) and cooling load, the Heating, Ventilation and Air-Conditioning (HVAC) system is identified as the major energy consumer in the plant. The AHU operation schedule in the office building is modified to reduce waste while accommodating the working schedule of employees. Motion detection lighting control is implemented in office areas to reduce waste from unnecessary lighting. Revision of the AHU operating schedule in manufacturing building can reduce electricity use by 16.5% while the implementation of other recommendations can save more than $50,000 in a six month period. A spreadsheet is developed to optimize the dehumidifier setting and the set point temperature of chilled water and off coil air.

The World Health Organization (WHO) estimates 488 million people worldwide suffer from a visual impairment and of these about 327 million have severe visual impairments. Some individuals with severe visual impairments can navigate and orient independently in well-known surroundings, but even for these people independent navigation and orientation are likely to be a challenge in unfamiliar places. To overcome these challenges, assistive technologies have been developed to support independent wayfinding tasks; however, those with severe visual impairments often experience frustration when they try to use assistive technologies since these technologies lack address the environmental factors that influence their independent wayfinding.
This research developed and evaluated the efficacy of a framework called an environmental user interface (EUI). In particular, this research explored whether or not the proposed EUI framework was effective when used with user-centered design (UCD) to design a wayfinding system to capture environmental requirements, thus aiding those with severe visual impairments. Two studies, the first of which consisted of a requirements elicitation and the second usability testing, were conducted. The studies revealed that the EUI framework was indeed more effective than the conventional UCD design method alone in identifying environmental factors, and participants with severe visual impairments preferred to use the prototype designed using UCD and the EUI framework.
The proposed EUI framework was found to be an effective way to enhance the design process as it played an important role in eliciting a greater number of environmental factors, and hence produced a device that was preferred by the users with visual impairments. Both prototypes influenced how well the wayfinding tasks were performed by the five participants with severe visual impairments, but the prototype implemented based on the requirements elicited by UCD and the EUI framework was much preferred by the participants.Ph.

Full textAbstract:
Introduction: Mechanisms facilitating mother-to-child transmission (MTCT) of HIV have not been elucidated. Small quantities of blood pass from mother to infant during childbirth, termed 'microtransfusion'; this is one possible mechanism for HIV entry into the infant's circulation. HIV-specific cellular immune responses have been detected in some uninfected infants born to HIV-infected women, indicating transient virus exposure or replication in these infants. Both microtransfusion and HIV-specific immune responses in infants born to HIV-infected women has not previously been investigated. Methods: 46 uninfected infants born to HIV-infected women were included in this study. Infants were grouped according to interventions utilised by the mother: none or antiretroviral therapy (ART; group A, n = 16), ART with elective caesarean section (elCS; group B, n = 12), highly active antiretroviral therapy (HAART) only (group C, n = 7), and HAART with elCS (group D, n = 11). HLA-A and -B alleles were typed for all mother-baby pairs to identify the non-inherited maternal allele (NIMA). Microtransfusion was detected using flow cytometry or by qPCR targeting the NIMA. HIV-specific immune responses were detected using 51Cr-release and IFN-?????? ELISpot assays. Results: Microtransfusion was detected in umbilical cord blood of 9 of 11 infants, and in peripheral blood of 4 of 11 infants up to 1 week old. One infant without detectable microtransfusion in umbilical cord blood had detectable maternal cells in peripheral blood. 8/46 infants had HIV-specific T cell responses, 5 were in group A, 2 in group B, and 1 in group C, while no infants in group D had detectable responses (p = 0.04). Blood samples from 2 of these 8 infants were also available for the analysis of microtransfusion. Microtransfused maternal cells were present in the umbilical cord blood of both infants. Conclusion: In this study, the number of infants with HIV-specific immune responses decreased with the use of MTCT interventions, indicating reduced exposure to HIV in these infants. This is the first study to demonstrate both microtransfusion and HIV-specific immune responses in uninfected infants. Microtransfusion may facilitate viral exposure, resulting in the development of potentially protective immune responses in infants born to HIV-infected women.

Full textAbstract:
It is common with significant differences between calculated and actual energy use in the building sector. These calculations are often performed with whole building energy simulation (BES) programs. In this process the analyst must make several assumptions about the studied building and its users. These calculations are often verified with measured data through the EUI benchmark indicator which is calculated by normalizing the annual energy use (from the grid) with the floor area. Due to the highly aggregated nature of the EUI indicator it is problematic to use this indicator to deduce erroneous assumptions in the calculations. Consequently, the learning process is often troublesome. Against this background, the main aim of this thesis has been to develop methods that can provide feedback (key building performance parameters) from measured data which can be used to increase simulation accuracy and verify building performance. For the latter, regression models have been widely used in the past for verifying energy use. This thesis has the focus on the use of regression analysis for accurate parameter identification to be used to increase the agreement between BES predictions and actual outcome. For this, a BES calibration method based on input from regressed parameters has been developed which has shown promising features in terms of accurate predictions and user friendliness. The calibration method is based on input from regressed estimations of air-to-air-transmission losses, including air leakage (heat loss factor) and ground heat loss. Since it is known that bias models still can give accurate predictions, these parameters have been evaluated in terms of robustness and agreement with independent calculations. In addition, a method has been developed to suppress the bias introduced in the regression due to solar gain. Finally, the importance of calibrated simulations was investigated. The regressed parameters were found to be robust with yearly variations in the heat loss factor of less than 2%. The regressed estimates of ground heat loss were also in good agreement with independent calculations. The robustness of the heat loss factor based on data from periods of substantial solar gain was also found to be high, with an average absolute deviation of 4.0%. The benefit with calibrated models was mainly found to be increased accuracy in predictions and parameters in absolute terms. With increased access to measured data and the promising results in this thesis it is believed that the presented regression models will have their place in future energy quantification methods for accessing energy performance of buildings.Det är vanligt med betydande skillnader mellan beräknad och verklig energi användning inom byggnadssektorn. Dessa beräkningar utförs ofta med hjälp av byggnads energi simulerings (BES) program där användaren måste göra ett flertal antaganden om den aktuella byggnaden och dess brukare. Det beräknade resultatet kontrolleras ofta i ett senare skede mot byggnadens faktiska behov av energi från nätet. I denna kontroll är det dock svårt att särskilja den energimängd som byggnaden behöver och den del som är kopplad till brukaren. Detta gör att lärdomarna som kan dras i denna verifieringsprocess ofta blir begränsade. Mot denna bakgrund, har det huvudsakliga syftet med denna avhandling varit att utveckla metoder som kan användas för att extrahera information om byggnadens prestanda från mätdata. De extraherade parametrarna skall kunna användas för att öka noggrannheten i prediktioner från BES modeller och för att verifiera byggnaders prestanda. Regression analys har ofta använts i det senare fallet i avseendet att verifiera energi användning. Denna avhandling fokuserar på att utveckla regressionsmodeller som ger en hög noggrannhet i modellens parametrar som möjliggör att de bl.a. kan användas för att kalibrera BES modeller och på så sätt minska den vanligt förekommande diskrepans mellan simulerat och faktiskt utfall. En BES kalibrerings metodik har utvecklats baserat på skattning av transmissions förluster ovan mark, inklusive luftläckage (värmeförlust koefficient) samt värmeförlust till mark (G) med hjälp av regressionsanalys. Denna kalibrerings metodik uppvisar lovande egenskaper i form av noggranna prediktioner och användarvänlighet. Goda prediktioner är dock ingen garanti för att modellens ingående parametrar är fysikaliskt rimliga. Därför har regressionsmodellernas parametrar utvärderats i termer av robusthet och överensstämmelse med oberoende beräkningar. Dessutom har en metod utvecklats för att minimerar solens inverkan på regressionsskattningarna. Slutligen har vikten av kalibrerade simuleringar undersökts. Parametrarna i de framtagna regressionsmodellerna visade sig vara robusta, med årliga variationer i värmeförlust koefficient mindre än 2%. Ytterligare visade sig G var i god överensstämmelse med oberoende beräkningar. Robustheten i värmeförlustfaktorn baserad på data från perioder av betydande solstrålning konstaterades också att vara hög, med en genomsnittlig absolut avvikelse på 4.0%. Fördelen med kalibrerade modeller visade sig främst vara en ökad noggrannhet i prediktioner och modell parametrar i absoluta tal. Med ökad tillgång till mätdata och lovande resultat i denna avhandling är det författarens övertygelse att de presenterade regressionsmodellerna kommer att ha sin plats i framtida bedömnings metoder av byggnaders energiprestanda.

Designing architecture is related to producing vast amounts of information based on constraints, experience or common sense, and at the same time, those designs are assisted by specialized software, but, are the results of those processes giving you advantage or are they leading you in the wrong way? For example, should you include shading elements or less glazing? Should you change the shape of the building or improve envelope specifications? This research is a start to understand how to approach to design problems related to solar geometry, recognize which variables are worth modifying, reduce potential of error when iterating, and take truly advantage of the output delivered by modeling tools.Master of Architecture

Full textAbstract:
El monóxido de europio EuO es un material ferromagnético que muestra una gran variedad de fenómenos físicos y se utiliza a menudo como sistema ideal. Cabe destacar el efecto Kerr, el transporte de espín y, para EuO , una transición metal-aislante con magnetorresistencia colosal. EuO es el único óxido binario conocido que se puede crecer termodinámicamente estable en contacto con silicio. Este óxido puede utilizarse para la inyección de espines ajustando su conductividad a la del silicio o también cómo barrera túnel. Mediante el dopaje, normalmente con lantánidos o Eu, puede aumentarse la temperatura de Curie por encima de los 69K. Las dificultades inherentes a la fabricación de películas delgadas de EuO hacen su aplicación difícil, porque forma fácilmente oxidos no magnéticos, Eu O o Eu O . En esta tesis se estudian también compuestos relacionados como EuS y Eu O .
En un primer intento se utilizó la deposición por láser pulsado, donde debido al alto contenido de oxígeno en la cámara se creció Eu O epitaxial. Este óxido de europio tiene aplicaciones en recubrimientos fotoactivos, almacenamiento de datos ópticos, pantallas fluorescentes y dispositivos microelectrónicos debido a su excelente comportamiento dieléctrico. Esta tesis presenta el primer ejemplo de crecimiento epitaxial de una película delgada de Eu O mediante técnicas en fase de vapor.
Se describen los intentos de depositar EuO mediante pulverización catódica a partir de un blanco metálico. Siendo esta técnica la preferida en aplicaciones industriales, se estudió el efecto de diferentes substratos, y de capas intermedias y de protección. La alta reactividad del Eu en el interior del plasma provoca una mala reproducibilidad de las deposiciones y la presencia simultánea de varios óxidos de Eu que se determinó mediante rayos X.
La deposición por MBE es actualmente la técnica preferida para conseguir crecimiento de EuO de alta calidad, porque ofrece un gran control de los parámetros críticos de la deposición. Gracias a su perfecta compatibilidad estructural, el YSZ facilita el crecimiento epitaxial de EuO. Hemos observado que se pueden superar problemas en el depósito mediante la introducción de una capa intermedia de MgO, con la que incluso se mejoró la cristalinidad de las capas. Al considerar las aplicaciones del EuO, el dopaje es relevante, porque permite el aumento de la temperatura de Curie y una modificación de la resistividad de varias órdenes de magnitud. Hemos demostrado que EuO dopado con un porcentaje muy bajo de Se muestra un gran aumento de la temperatura de Curie. Como no existe ningun modelo para este caso concreto en la literatura, se analiza el mecanismo que puede dar lugar a este comportamiento atípico.
En esta memoria también se presentan las primeras medidas nanocalorimétri-cas de películas delgadas de EuO. Aparte de mejorar el sistema de medición, se ha desarrollado un formalismo matemático que permite un cálculo más preciso de la capacidad calorifica. Se han medido capas de EuO con espesores de unos pocos nanómetros. Se observa una disminución de las temperaturas de Curie y Debye al disminuir el espesor. También se modifica la entropía magnética, debido al aumento de átomos con baja coordinación a través de la superficie o las juntas de grano.
El último capítulo trata de barreras ferromagnéticas y aislantes de EuS, que son menos reactivas y similares a las barreras de EuO, utilizadas para hacer medidas de transporte. El efecto de la intercara entre EuS y aluminio superconductor se ha investigado mediante la introducción de capas delgadas intermedias de Cu y Si en las juntas. Se ha observado un pico anómalo a bias cero, que tiene un comportamiento histerético cuando se aplica un campo magnético. La polarización de espín máxima que se obtuvo fue del 56%.Ferromagnetic europium monoxide (EuO) displays a huge variety of physical phenomena and due to its simple structure it is often used as a model system. It shows magneto-optic Kerr effect, spin-dependent transport and, in the case of Eu doped EuO, a metal-insulator transition showing a colossal magnetoresistance. EuO is also the only known binary oxide that can be grown in a thermodynamically stable form in contact with silicon. The application of EuO for spin injection either by matching its conductivity or by using it as insulating tunnel barrier has been shown. Its relatively low Curie temperature of 69 K can be enhanced by doping, normally with lanthanides or metal europium. However, problems of fabricating thin EuO films make its implementation difficult. Europium monoxide readily forms higher, non-magnetic oxides Eu O and Eu O , when exposed to air. Also recent studies still report on considerable amounts of present in the samples. This thesis focuses on the growth, magnetic properties and heat capacity of EuO. Also, related compounds, such as EuS and Eu O are studied. Several techniques, such as sputtering, molecular beam epitaxy (MBE) and pulsed laser deposition (PLD), are used to obtain high quality EuO thin films on yttria-stabilized cubic zirconia (YSZ) (001) and silicon substrates. In a first step the growth of epitaxial EuO on YSZ was attempted using pulsed laser deposition. Due to the high oxygen content in the chamber epitaxial Eu O was grown. This is the most used form of the europium oxides nowadays, as it can be implemented in photoactive coating, optical data storage , and fluorescent displays due to its luminescence properties. Due to its high dielectric strength recently it was also used in microelectronic devices as high dielectric gates. However, studies on high quality epitaxial Eu O are still scarce. To our knowledge this PhD represents the first example of epitaxial growth of a thin film of Eu O by vapor phase techniques. In order to make EuO accessible for industrial purposes sputter deposition is the preferred option. Attempts of EuO deposition by sputtering from a metal target are described. The effect of different substrates, inter- and capping layers is discussed. We show that the high reactivity of Eu inside the plasma leads to bad reproducibility of depositions. X-ray measurements were used to determine the approximate content of the Eu-EuO-Eu O films. At the moment MBE deposition is the technique of choice for high quality EuO growth, as it offers great control of all critical deposition parameters. Due to its perfect lattice match YSZ eases the growth of epitaxial EuO. By introducing an MgO buffer layer problems in the deposition could be overcome and crystallinity was enhanced. When considering applications of EuO, doping is an important topic, since it allows the enhancement of the Curie temperature and the tuning of the resistivity over various orders of magnitude. We have shown that doping EuO with a very low percentage of Se, surprisingly, shows a large enhancement of the Curie temperature. As no model exists for this case, the mechanism for the enhancement of the Curie temperature by Se is discussed. The first nanocalorimetric measurements on EuO thin films are presented. Apart from improving the measurement system, a mathematical formalism was developed to allow a more accurate calculation of the heat capacity. Thin films of EuO could be measured in thicknesses down to a few nanometers, where size effects come to play. A decrease of the Curie and Debye temperature as well as the magnetic entropy is observed due to the decrease in the number of nearest magnetic interaction neighbors at the surface. Ferromagnetic insulating EuS barriers - similar to EuO barriers - were also used along this thesis for transport measurements, because they are less reactive and therefore can be deposited in good quality in evaporation chambers with a higher base pressure. The effect of the interface between EuS and superconducting aluminium is investigated by introducing thin Cu and Si interlayers in SC-FI-SC junctions. A zero bias peak is observed, which is hysteretic with respect to an applied magnetic field. The origin of this feature is discussed. The maximum spin polarization that was obtained is about 56 %.

Full textAbstract:
Ce travail de thèse porte sur l'étude des verres alumino-silicatés de calcium dopés à l'europium et le processus de leur cristallisation sous forme des vitrocéramiques dans le cadre de la recherche de nouveaux phosphores pour application LED à émission blanche. Nous avons étudié trois échantillons vitreux avec différentes teneurs en silice et avons élaboré des vitrocéramiques cristallisées. La caractérisation des verres et des vitrocéramiques a été réalisée par différentes techniques expérimentales : l'analyse thermique, la diffraction des rayons X et la spectroscopie de diffusion Raman. Les propriétés spectroscopiques de l'ion europium dans les verres et les vitrocéramiques synthétisés ont été étudiées. Le contrôle de la cristallisation des vitrocéramiques GC34 et GC50 par la diffraction des rayons X a permis d'identifier deux phases la mélilite et l'anorthite. Dans le cas de la vitrocéramique GC7, une seule phase alumino-calcique qui est la mayenite est cristallisée majoritairement. L'étude par la spectroscopie de diffusion Raman a permis d'une part, de suivre l'évolution de la cristallisation pendant les traitements thermiques en surface et en profondeur dans l'ensemble des vitrocéramiques. Nous avons montré que le processus de cristallisation a eu lieu en surface des échantillons et correspond typiquement à une nucléation hétérogène. D'autre part, une étude comparative avec des échantillons naturels analogues prise de la base de données RRUFF nous a permis de valider l'ensemble des résultats trouvés. Dans le cas des vitrocéramiques GC34 et GC50, les mesures des spectres d'émission et les durées de vie de l'ion Eu3+ montrent bien son incorporation dans les phases cristallines formées. L'ion Eu3+ tend à occuper seulement les sites Ca2+ (CN= 8) de la mélilite majoritaire dans la vitrocéramique GC34 alors, qu'il tend à s'incorporer dans les sites Ca2+ (CN= 6 et 7) et Ca2+ (CN=8) respectivement, des phases anorthite et mélilite formées dans la vitrocéramique GC50. Ces résultats ont été confirmés par les mesures d'affinement de raies. L'étude des spectres d'émission de l'ion Eu2+ a permis de mettre en évidence une modification de son environnement durant la cristallisation traduite par son incorporation dans les sites Ca2+ après réduction de l'ion Eu3+ pendant les recuits. Dans le cas de la vitrocéramique GC7, les spectres d'émissions et les mesures du déclin de luminescence de l'ion Eu3+ montrent bien que l'ion Eu3+ est incorporé dans la phase mayenite formée. En terme d'application, les mesures des coordonnées trichromatiques suggèrent que la dévitrification des verres semble être une technique efficace permettant d'obtenir de nouveaux matériaux luminophores (LED blanches) à émission intensifiée (cas des vitrocéramiques GC34 et G50) et accordable en modifiant leur composition et l'excitationThis work concerns the study of calcium aluminosilicate glass doped with europium and their process of crystallization as glass-ceramics as part of the search for new phosphors for white LED application. We studied three glass samples with different silica contents and have elaborated crystallized glass-ceramics. Characterization of glasses and glass-ceramics was performed by different experimental techniques: thermal analysis, X-ray diffraction and Raman spectroscopy. The spectroscopic properties of the europium ion in the glass and glass-ceramic synthesized were studied.Control of crystallization of GC34 and GC50 glass-ceramics by X-ray diffraction have been identified two phases, melilite and anorthite. In the case of the GC7 glass-ceramic, a single aluminum calcium phase, mayenite which crystallized predominantly. The study by Raman spectroscopy allowed to follow the evolution of the crystallization during heat treatment in the surface and of glass-ceramics. We have shown that the crystallization process initiate at the surface of the samples and corresponds typically to a heterogeneous nucleation. On the other hand, a comparison with similar natural samples allowed us to validate all the identifications.In the case of GC34 and GC50 glass-ceramics, emission spectra and lifetimes of Eu3+ ion clearly show its incorporation into the new-formed crystalline phases. The Eu3+ ion occupy the Ca2+ sites (CN = 8) in the major mélilite phase of the the GC34 glass-ceramic while, it incorporates the Ca2+ sites (CN = 6 and 7) and Ca2+ (CN = 8) of anorthite and mélilite phases formed in the GC50 glass-ceramic, respectively. These results were confirmed by Fluorescence Line Narrowing (FLN) measurements. The study of emission spectra of the Eu2+ ion allowed highlighting changes during crystallization associated with the reduction of the Eu3+ ions during annealing. In the case of the low silicate GC7 glass-ceramic, emission spectra and lifetimes measurements of the Eu3+ ion show that the Eu3+ ions are incorporated into the mayenite phase. In terms of application, the analyses of the trichromatic coordinates suggest that the glass devitrification appears to be an efficient technique to achieve new white LED phosphor materials with intensified (mainly for GC34 and G50 glass-ceramics) and tunable emission by varying composition and/or excitation

This is an analytical study about the structural aspects of Quassus for clarinet solo, by Eli-Eri Moura. The aim of the work was to propose suggestions and instructions that may assist the performer with his interpretative choices. The text is divided in seven chapters. The first three introduce the goals of the work, contextualize and define the terms concerning the research, and present the methodology employed. Chapters 4 and 5 explain the compositional processes used by Moura in the piece, establishing a comparison with other works by the same composer. Chapter 6 provides a structural analysis of Quassus in light of these same compositional processes. Finally, Chapter 7 presents some considerations on performance and interpretation that emerged as concluding results of the study carried out in the previous chapters.

Full textAbstract:
Electronic data interchange (EDI) är en teknik vilken används för att utbyta elektroniska dokument mellan köpare och säljare. Dessa dokument överförs på en strikt elektronisk standardiserad väg, dokumenten kan vara fakturor, beställningsformulär, leveransplaner etc. EDI har funnits i över 25år och är vida spridd över världen. För att använda EDI krävs det stora resurser i form av kapital och kunskap. Små och medelstora företag har ofta inte de resurser som krävs för att kunna använda EDI.
Nya tekniker utvecklas ständigt. Extensibel Markup Language (XML) är en ny teknik vilken är avsedd att användas främst på Internet. XML delar upp dokumenten med hjälp av etiketter vilket hjälper läsaren att identifiera innehållet i dokumenten. XML har väckt EDI-samhällets intresse då XML anses ha kapaciteten att kunna användas som ett EDI-format samtidigt som XML är Internetanpassat vilket betyder att EDI enklare skulle kunna användas på Internet.
I mitt examensarbete har jag utrett om EDI-användande företag avser använda XML/EDI. Jag har genomfört intervjuer för att besvara problemformuleringen. Resultaten jag kommit fram till är att företagen avser använda XML/EDI om en ordentlig standard blir framtagen. Företagen är dessutom positivt inställda till XML/EDI samt Internetbaserad EDI. Anledningen till den positiva inställningen är främst att XML/EDI samt Internetbaserad EDI skulle innebära lägre kostnader vilket i sin tur skulle innebära att även små och medelstora företag skulle kunna använda tekniken.

Abstract: This is a creative insubordination research, in which, from my interlaced life narratives, a plot is constructed that tells how I, a mathematics teacher and mathematics teacher educator, achieve to turn myself a teacher and a teacher educator, in addition of a mathematics education researcher. As an autobiographical narrative research, the work presents features strongly linked to qualitative research. During the investigation of my (self)education and identitary processes, as a subject of experience, I analyze several critical episodes throughout the text that show signs of live contradiction and/or creative insubordination to compose the investigative body of this thesis. Some of these moments were identified from audiotapes recorded in a community course, others were deepened with the interventions of fellow travelers who experienced the narrative text with me, helping in the production of self. It is a characteristic of this narrative journey producing meaning out of various artifacts such as books, texts, films, music, e-mails, proofs and photos that are relevant to the experiences considered at the book were used. With all these elements in hand, I was able to construct a text divided into two parts: the main part, which forms a book for teachers and, in parallel, numerous footnotes, which tell a more academic story, in which I analyze what is being said in the book. It was used the methodological course, besides an ethical care, to treat the narrative plot and the anal... (Complete abstract click electronic access below)

Full textAbstract:
Diese Arbeit beschäftigt sich mit theoretischen Untersuchung von Oberflächenzuständen in ferromagnetischen Halbleitern. Einleitend wird ein analytisches "tight-binding"-Modell zur Beschreibung der Oberflächenzustände. Es liefert Aussagen zur Existenz von Oberflächenzuständen, zu deren spektralen Gewicht und Position bezüglich der Energie. Das Kondogitter-Modell wird verwendet, um Korrelations- und Temperatureffekte sowie Oberflächenzustände zu beschreiben. Dies erfolgt zunächst für sc-(100)-Modellfilme im Rahmen des sf-Modells. Die temperaturabhängigen der Oberflächenzustände zeigen abhängig vom Ort in der Brillouinzone sowie den "hopping"-Parametern in der Oberfläche sowohl Stoner-artiges als auch "spin-mixing"-Verhalten. Mit wachsender Temperatur werden Lebensdauereffekte in den Spektren sichtbar. Das Kondogitter-Modell (KLM) wird auf die Mehrbandsituation zum df-Modell verallgemeinert, um eine Beschreibung der Prototypen für magnetische Halbleiter EuS und EuO zu erreichen. Durch die Kombination von LDA-Bandstrukturrechnungen mit Vielteilchenrechnungen zum Multiband-KLM ist es gelungen, die ausgeprägte Temperaturabhängigkeit des unbesetzten 5d-Leitungsbandes und das Verhalten der Oberflächenzustände in EuS- und EuO-Filmen realistisch zu beschreiben. Der exakte Grenzfall des Kondogitter-Modells, das magnetischen Polaron (T=0), ermöglicht Kombination von ab-initio-Bandstrukturrechnungen und der Vielteilchentheorie ohne das Auftreten von Doppelzählungen relevanter Wechselwirkungen. Sowohl in EuO als auch in EuS temperaturabhängige Oberflächenzustände beobachtet werden, die im Fall von EuS jedoch schwerer nachzuweisen sind, da sie im Energiebereich des Volumenbandes auftreten. Die für EuS und EuO berechneten Rotverschiebungen sowie die dickenabhängige Magnetisierung von EuS stimmen hervorragend mit experimentellen Befunden überein. Eine Vielzahl von Korrelationseffekten ist mit wachsender Temperatur in den Spektren der unbesetzten Europium-5d-Bänder zu beobachten.This work is dedicated to the theoretical investigation of surface states in ferromagnetic semiconductors. After the introduction a exact solvable analytical model is presented. It figures out for given conditions if surface states exist, which spectral weight they have, and at which position in energy they can be found. Thereafter the Kondo-Lattice-Model (KLM) is used to describe correlation and temperature effects. The description focuses initially to the sc-(100) model films in the sf-model. The resulting temperature dependent surface states both Stoner behavior and "spin-mixing" behavior dependent on the chosen hopping parameters and the position in the two dimensional Brillouin zone. With increasing temperature (up to Tc) lifetime effects arise in the spectra. In conclusion the KLM is extended to the multi-band situation (df-Model) in order to provide a description of the prototypes of magnetic semiconductor EuS and EuO. We succeed in describing the distinct temperature dependence of the unoccupied 5d-conduction band and the behavior of the surface states in EuS and EuO films realistically by a combination of a LDA band-structure calculation and the manybody theory. The exact limiting case of the KLM (T=0) -the magnetic polaron- allows a combination of a ab-initio band-structure calculation and manybody theory without double counting of any relevant interaction. The presented theory provides numerous results. In EuO and EuS can be found temperature dependent surface states. In case of EuS it''s detection is much more complicated thus the surface state energies are located inside the energy range of the bulk band. The famous redshift in EuS and EuO and the thickness dependent film magnetization of EuS agree very well with the experimental results. A lot of correlation effects are present in the calculated unoccupied Europium 5d bands. With increasing temperature these effects become stronger.

Full textAbstract:
Phytophthora ramorum is causing major damage to the economy and the natural ecosystems of the countries where it is found. There are four different lineages of P. ramorum: NA1, NA2, EU1 and EU2. EU2 has only been found in Northern Ireland and southwest coast of Scotland The populations EU1 and EU2 on the island of Ireland were studied. The results showed that all the isolates collected from the Republic of Ireland were EU1, as In the rest of Europe and the majority of the Isolates from Northern Ireland and Scotland were EU2. Further study resulted in phylogenetic trees that suggested that the EU1 population in the Republic of Ireland is the result of multiple introductions brought by plant trade from Europe. Additionally! the EU2 population in Northern Ireland is the results of a single Introduction, probably brought from Asia, and then spread across the country. The interaction of P. ramorum with its most affected host In the UK, larch, was studied. High throughput sequencing was performed with Illumlna 2000 Hiseq in European and Japanese larch trees infected with the lineages EU1 and EU2. This showed a larger number of general defence genes activated in European larch against the pathogen, along with a larger number of Inactivated genes In Japanese larch, supporting the idea that European larch is more resistant to P. ramorum. Some defence molecular pathways were studied, showing that European larch activates more genes in each specific pathway. A selection of genes involved in the different defence pathways were studied showing that the highest peak of plant defence against the pathogen occurs 3 days after the inoculation, suggesting that for the plant It Is important to react quickly in order to survive the pathogen attack.

Full textAbstract:
A central principle within UN and EU policy is environmental policyintegration (EPI), aiming at integrating environmental aspirations, targetsand requirements into sector policy in order to promote sustainabledevelopment. The focus of this study is EPI in bioenergy policy. Bioenergy isa renewable energy source of increasing importance in the EU and Swedishenergy mix. At the same time, it is debated how environmentally friendlybioenergy really is. Furthermore, bioenergy can be considered both a multisectorand a multi-level case, since bioenergy is produced in many differentsectors and bioenergy policy is formulated and implemented on differentlevels. Therefore, EPI in bioenergy policy is here analysed over time in twosectors (energy and agriculture) and on three levels (EU, national, subnational).A cognitive, policy learning perspective on EPI is adopted, tracingEPI through looking for reframing of policy towards incorporatingenvironmental objectives in policy rhetoric and practice. Furthermore,institutional and political explanations for the development are discussed.Paper I analyses EPI in Swedish bioenergy policy within energy andagriculture. Paper II analyses institutional conditions for multi-sector EPI inSwedish bioenergy policy. Paper III analyses EPI in EU bioenergy policywithin energy and agriculture. Paper IV analyses sub-national EPI in thecase of the Biofuel Region in north Sweden. The material examined consistsof policy documents complemented by semi-structured interviews. Together, the four papers provide a more complex and holistic picture ofthe EPI process than in previous research, which mainly has focused onstudying EPI in single sectors and on single levels. The study shows thatpriorities are different on different levels; that EPI has varied over time; butthat EPI today is detectable within bioenergy policy in both studied sectorsand on all levels. Policy learning in bioenergy is found to be mainly a topdownprocess. Furthermore, policy coherence between sectors and levels;long-term goals; and concrete policy instruments are found to be importantboth for the EPI process as such and for the outcomes from this process.However, when attempting to marry different goals, such as growth, securityand sustainability, in line with the three-tiered (economic, social, ecologic)sustainable development concept, environmental aspects risks not to beprioritised when goal conflicts arise. The study proposes that future researchboth continues the analysis of multi-sector and multi-level EPI, and furtherexplores to what extent ecological sustainability is improved by EPI.

Full textAbstract:
In this paper the compositional issues and techniques employed in my D.Mus. Thesis Composition Noite dos Tambores Silenciosos (for symphony orchestra) are discussed. The piece, constituted of three linked parts, exhibits a counterpoint of three distinct kinds of music as the main vehicle of the musical discourse.Two of these musics are connected with Maracatu de Baque Virado and Maracatu Rural, popular musical manifestations found in Pernambuco, a state in northeast Brazil. In a "defragmentation" process, reference materials from the Maracatus are abstractly fragmented and reconstructed according to a technique I call Zin-Zout, implementing in the music a continuous state of transformation, back and forth between micro and macro dimensions. The third kind of music, free of folk references, follows a transformational process built up according to a "palimpsest" technique. In this transformation the hierarchy of the musical parameters changes along with the units of the musical content.
These procedures involve not only pitch and rhythm, but also other parameters like timbre, density and register in a structural way, as building elements of the content and form of the work.
The defragmentation process establishes some predetermined compositional paths, but permits micro- and macro-level decisions based on intuitive considerations, especially in the manipulation of orchestration and micro rhythms. More systematic, the organization of pitch involves a limited serialism and a variety of modal treatment.

Full textAbstract:
Tutkielman tarkoituksena on selvittää, kuinka kielenopetus tapahtuu esi- ja alkuopetuksessa. Keskityn selvittämään, kuinka lastentarhanopettajat ja opettajat opettavat kieltä, millaista opetusmateriaalia he käyttävät, sekä kuinka he kannustavat, kehuvat ja motivoivat lapsia. Tutkimuksen edetessä kiinnitin huomiota myös siihen, millainen oppimisympäristö lapsilla on.
Tutkimukseni kohteena on kolme lastentarhanopettajaa sekä kolme alkuopetuksen opettajaa. Kaikki tutkimushenkilöt ovat naisia ja he työskentelevät Länsi-Suomen läänissä. Tutkielmaan osallistui yhteensä kaksi alakoulua ja kaksi esikoulua. Olen kerännyt aineistoni observoimassa ja haastattelemalla opettajia. Jaoin haastattelun viiteen eri teemaan ja analyysivaiheessa lähdin purkamaan haastatteluja näiden teemojen perusteella. Tarkastelin lastentarhanopettajien ja opettajien vastauksia ja tein niistä yhteenvedon. Opettajat ja lastentarhanopettajat olivat kielenopetuksesta hyvin samoilla linjoilla, mutta muutamia mielipide-eroja oli myös havaittavissa.
Esikoulussa herätellään lapsen mielenkiintoa kieltä ja kirjaimia kohtaan esimerkiksi satujen, lorujen, riimien ja laulujen avulla. Opetustuokiot eivät kestä kauaa, joten lasten motivaatio säilyy ja he haluavat oppia. Opetus on leikinomaista ja lasten kanssa pyritään keskustelemaan paljon. Esikoululaiset harjoittelevat suullisesti esimerkiksi aakkosia, äänteitä ja tavuja. He saavat harjoitella käden ja silmän yhteistyötä ja hienomotoriikkaa esimerkiksi kirjoittamalla kirjaimia ja tekemällä hahmotustehtäviä. Esikoulussa on myös käytössään esimerkiksi kuvia, tavukortteja ja oppimispelejä, joilla lapset saavat harjoitella kielellisiä taitojaan. Lapset saavat oppia omaan tahtiin ja lapsia pyritään kannustamaan ja kehumaan sanallisesti. Lapset ovat motivoituneita tekemään tehtäviä, sillä he saavat tehdyistä tehtävistä leimoja. Koulussa lapset joutuvat istumaan paikoillaan suurimman osan koulupäivästä. Oppilaat kertaavat jo esikoulussa opittuja asioita ja oppivat pikkuhiljaa lukemaan ja kirjoittamaan. Opettajien mielestä oppilailla on aluksi suuria tasoeroja, riippuen siitä, kuinka paljon he ovat harjoitelleet kielellistä toimintaa esikoulussa. Tasoerot tasaantuvat pikkuhiljaa ja mikäli tarvetta, niin oppilaat saavat erityistä tukea esimerkiksi opettajalta, avustajalta ja erityisopettajalta. Opettajat seuraavat opetussuunnitelmaa ja etenevät sen mukaisesti. Oppitunnit pyritään pitämään vaihtelevina, jotta oppilaiden ja myös opettajan motivaatio säilyisi ja oppiminen olisi mieluisaa. Opettajat käyttävät apunaan esimerkiksi oppikirjoja, omatekemää materiaalia, pelejä ja kuvia. He kannustavat ja motivoivat oppilaita kehujen, leimojen ja tarrojen avulla.
Tutkielmani on mielestäni melko luotettava ja yleistettävä ja uskon, että päästäisiin samoihin tuloksiin, mikäli tutkielma tehtäisiin uudestaan. Mikäli tutkittavia henkilöitä olisi ollut enemmän, olisi tutkielma myös luotettavampi.

Full textAbstract:
Background: It has been shown that EDI can yield positive effects within companies. Which effects are possible for a company to direct assign to the introduction of EDI and is it possible to estimate the total effect.
Purpose: The purpose of this study is to estimate and analyze the effects of using EDI in electronic business. We also want to contribute with a model for measure and estimate the effects of EDI.
Accomplishment: We have studied literature concering EDI and realized a preliminary studie in form of interviews with experts to establish deeper knowledge of EDI. We have also tried to estimate the effects obtained in companies in three different businesses, power, government and transport industry.
Result: To obtain as good effects as possible it is important that the co- oporation is built on trust and engagement. Before implementing the EDI-system a thorough overhaul of the processes in the company should be done, involving both the top managers and the staff. Internet can be used to achieve minimal cost and it is important to limit the information sent by EDI to only send the information demanded. Finally companies also should mediate the advantages of EDI inside the organisation to make the co-operators realize the good effects obtained by EDI.

Regleringen av spelmarknaden i allmänhet och främjandeförbudet i synnerhet har i ett flertal fall varit föremål för prövning av svenska domstolar.

Sedan Sveriges inträde i EU har den svenska regleringens förenlighet med EU:s regler om fri rörlighet prövats av svenska domstolar ett flertal gånger. Det senaste avgörandet i raden utgörs av Svea Hovrätts dom från den 22 juni 2011 där straffstadgandet i 54 § lotterilagen underkändes p.g.a. att det ansågs strida mot EU-rättens diskrimineringsförbud. Domen har överklagats till HD som meddelat prövningstillstånd. 38 § i lotterilagen har, trots massiv kritik, ännu inte underkänts av någon domstol. Genom sina många avgöranden på spelområdet har EU-domstolen utvecklat en metod för hur nationella och i sig handelshindrande spelregleringar skall bedömas. Domstolen har gått, från att i början ha haft en tämligen tillåtande syn på dessa, till att i sina senare avgöranden ha valt en aningen strängare linje. Inte minst gäller detta frågan hur expansiv en stats marknadsföringspolitik för spel får vara. I och med att spel och lotterier ännu inte blivit föremål för harmonisering är det dock fortfarande till stor del upp till medlemsstaterna själva att bestämma hur de vill reglera spelmarknaden, detta så länge utformningen är icke-diskriminerande, proportionerlig och tillämpas på ett sammanhängande och systematiskt sätt som inte inskränker den fria rörligheten mer än nödvändigt. Den svenska ordningen med främjandeförbud skulle främst kunna kritiseras för att ha ett annat mål än de angivna och istället syfta till att stärka statskassan, något som inte är ett giltigt skäl för att inskränka den fria rörligheten för tjänster eller etableringar. Åtminstone kan det, särskilt mot bakgrund av den expansiva marknadsföringspolitik som bedrivs av de statliga spelbolagen och det faktum att det inte är förbjudet för svenskar att spela på utländska lotterier, ifrågasättas om ordningen är sammanhängande och systematisk såtillvida att den tjänar till att minska spelandet. Hittills har EU-domstolen främst behandlat nationella spelmonopol eller särregleringars förenlighet med reglerna om fri rörlighet på den inre marknaden. En intressant och i dagsläget obesvarad fråga är därför hur domstolen skulle resonera ang. en sådan ordnings förenlighet med EU:s konkurrensregler. AB Svenska Spel är ett bolag som av staten fått ett exklusivt tillstånd att bedriva vadhållning på den svenska marknaden för spel och lotterier. Om bolaget kan anses missbruka sin dominerande ställning på denna marknad skulle en möjlighet kunna vara att indirekt angripa den svenska regleringen genom art. 102 kombinerat med art. 106.1 FEUF. För att nå framgång med detta torde dock krävas att staten kan sägas ha medverkat till företagets konkurrensbegränsande beteende eller att själva regleringen är konkurrensbegränsande i sig, samt att inte undantagsregeln i art. 106.2 är tillämplig.

Previous issue date: 2012-02-28The business related to equines in Brazil has an important participation in activities as leisure, culture and tourism, being responsible for millions of jobs. The equine distemper caused by Streptococcus equi subsp. equi is a disease of the respiratory tract with economical impact, generating losses with treatment and reduction in the animal performance. To solve this problem, prophylactic measures, such as the vaccination, are important. However, available commercial vaccines do not offer protection to more than 50% of the vaccinated animals. Several studies are being performed aiming the achievement of an efficient vaccine against the Adenitis, where several virulence factors are being evaluated as possible vaccine antigens, specially the M protein (SeM). Thus, the present work aimed the development and evaluation of a recombinant vaccine to the control of the equine distemper composed of the SeM antigen co-administrated with the recombinant Heat-labile enterotoxin B subunit of Escherichia coli (rLTB) and/or aluminium hydroxide (Al(OH)3). A total of 72 female BALB/c mice, divided into eight groups and 18 horses, divided into six groups, were inoculated by intramuscular or intranasal routes. The results obtained in the experiments showed that the rSeM was innocuous and immunogenic in both evaluated species, stimulating the production of specific immunoglobulin anti-rSeM without the addition of immunological adjuvant. Both adjuvant rLTB and Al(OH)3 were not capable to increase the titer of immunoglobulin anti-rSeM in mice, while in horses, the treatment rSeM + rLTB (IM) showed a significant increase in the level of seric immunoglobulin IgG anti-rSeM. Interestingly, the production of anti-rSeM secretory IgA in the upper respiratory tract has a significant increase in horses treated with rSeM + Al(OH)3 (IM). This result is promising to further studies with rSeM as an antigen for vaccines, as well as is the administration of rLTB as an immunological adjuvant.
A equinocultura no Brasil ganha espaço em setores ligados ao lazer, cultura e turismo, sendo responsável por milhões de empregos. A Adenite Equina causada pelo Streptococcus equi subsp. equi é uma doença do aparelho respiratório de elevado impacto econômico, gerando gastos com mão-de-obra e perda de desempenho dos animais. Para amenizar este problema, medidas profiláticas são importantes, como por exemplo, a vacinação. Porém, as vacinas disponíveis no mercado protegem apenas 50% dos animais. Vários estudos vêm sendo realizados para obtenção de uma vacina mais eficiente contra a Adenite, onde vários fatores de virulência do patógeno estão sendo avaliados como possíveis antígenos vacinais, com destaque para a proteína M de S. equi (SeM). Com base nisso este trabalho objetivou o desenvolvimento e avaliação de uma vacina recombinante para controle da Adenite Equina, utilizando como antígeno a rSeM e como adjuvantes a subunidade B da enterotoxina termolábil de Escherichia coli (rLTB) e ou hidróxido de alumínio (Al(OH)3). Para este estudo foram utilizados 72 camundongos Balb/c fêmeas divididos em 8 grupos e 18 cavalos divididos em 6 grupos, inoculados por via IM ou IN. Os resultados mostraram que a rSeM foi inócua e imunogênica para ambas as espécies avaliadas, estimulando níveis significativos de imunoglobulinas (lgs) anti-rSeM sem a necessidade de uso de qualquer adjuvante imunológico. Os adjuvantes rLTB e Al(OH)3 não foram capazes de incrementar significativamente os títulos de lgs antirSeM em camundongos, enquanto que em cavalos o tratamento rSeM + rLTB (IM) promoveu um aumento significativo no título sérico de IgG anti-rSeM. Interessantemente, a produção de IgA secretória anti-rSeM no trato respiratório superior de cavalos teve aumento significativo no tratamento com rSeM + Al(OH)3 (IM). Estes resultados são promissores para a continuidade de estudos visando a utilização da rSeM como antígeno vacinal. Da mesma forma, o uso da rLTB como adjuvante em vacinas para cavalos parece ser promissor.

Full textAbstract:
Tässä pro gradu -tutkielmassa perehdytään huutokauppateorian perusteisiin. Työssä keskitytään vertailemaan myyjän tuottoa yhden kohteen huutokauppamuotoisissa allokointimekanismeissa. Pääpaino on korkeimman ja toiseksi korkeimman hinnan huutokaupoissa. Ohessa tutkitaan myös tarjouskilpailuun ostajan ominaisuudessa osallistuvien optimaalisia tarjousstrategioita. Tutkielman päälähteinä on käytetty Vijay Krishnan teosta Auction Theory sekä Paul Klempererin teosta Auctions: Theory and Practice.
Työn ensimmäisissä kappaleissa esitellään siinä tarvittavaa matemaattista teoriaa sekä yleisimpiä huutokauppamalleja. Tutkielman perusta on tuottojen yhtäsuuruuden lause (engl. revenue equivalence theorem), joka esitetään ja todistetaan neljännessä kappaleessa. Sen mukaan myyjän huutokaupasta saama tuotto on yhtä suuri riippumatta käytettävästä huutokauppamallista, kun tietyt ehdot täyttyvät. Lauseen ehdot ovat kuitenkin käytännön kannalta katsoen varsin vahvat, joten niistä poikkeaminen luo mahdollisuuksia laajemmalle tutkimukselle. Työn loppupuolella tutkitaankin, kuinka myyjän eri mekanismeilla saatava tuotto muuttuu, kun kustakin ehdosta luovutaan vuorotellen.
Ensimmäisenä otetaan käsittelyyn tilanne, jossa huutokauppaan osallistuu riskinottoon halukkaita tarjoajia. Kappaleessa viisi tutkitaan, kuinka myyjän kannattaa reagoida toisistaan poikkeaviin ostajaehdokkaiden arvotusten jakaumiin. Kuudennessa kappaleessa lähestytään tuottojen yhtäsuuruuden lausetta keskenään riippuvaisista arvotuksista käsin.

Full textAbstract:
The main goal of my thesis is the evaluation of Eni SpA Corporation from the sight of the credit analyst. The credit analysis starts with the macroeconomic analysis that explains the main macroeconomic factors that affect the corporation from the outside, such as: economic growth, inflation, financial stability and unemployment. The energy outlook gives the drivers of the energy demand change mainly in the coming 30 years. Qualitative analysis is rich in general description about the corporation and gives a detailed outlook on production and services that the corporation is specialized in. The largest part of the analysis covers financial analysis, important to understand the financial profile of the company, its management, strengths and weaknesses. This work ends up with the analyst's recommendation on the creditworthiness of Eni SpA.
