This paper is a study of Polish-English machine translation, where the impact of various types of errors on cohesion and comprehensibility of the translations was investigated. The following phenomena were in focus: 1. The most common errors produced by current state-of-the-art MT systems for Polish-English MT. 2. The effect of various types of errors on text cohesion. 3. The effect of various types of errors on readers’ understanding of the translation.

The applicability of CFD codes for two-phase flows has always been limited to special cases due to the very complex nature of its interface. Due to its tremendous computational cost, methods based on direct resolution of the interface are not applicable to most problems of practical relevance. Instead, averaging procedures are commonly used for these applications, such as the Eulerian-Eulerian approach, which necessarily means losing detailed information on the interfacial structure. In order to allow widespread application of the two-fluid approach, closure models are required to reintroduce in the simulations the correct interfacial mass, momentum, and heat transfer. It is evident that such closure models will strongly depend on the specific flow pattern. When considering vertical pipe flow with low gas volume flow rates, bubbly flow occurs. With increasing gas volume flow rates larger bubbles are generated by bubble coalescence, which further leads to transition to slug, churn-turbulent, and annular flow. Considering, as an example, a heated tube producing steam by evaporation, as in the case of a vertical steam generator, all these flow patterns including transitions are expected to occur in the system. Despite extensive attempts, robust and accurate simulations approaches for such conditions are still lacking. The purpose of this dissertation is the development, testing, and validation of a multifield model for adiabatic gas-liquid flows at high gas volume fractions, for which a multiple-size bubble approach has been implemented by separating the gas structures into a specified number of groups, each of which represents a prescribed range of sizes. A fully-resolved continuous gas phase is also computed, and represents all the gas structures which are large enough to be resolved within the computational mesh. The concept, known as GENeralized TwO Phase flow or GENTOP, is formulated as an extension to the bubble population balance approach known as the inhomogeneous MUltiple SIze Group (iMUSIG). Within the polydispersed gas, bubble coalescence and breakup allow the transfer between different size structures, while the modeling of mass transfer between the polydispersed and continuous gas allows including transitions between different gas morphologies depending on the flow situations. The calculations were performed using the computational fluid dynamic code from ANSYS, CFX 14.5, with the support of STAR-CCM+ v8.06 and v9.02. A complete three-field and four-field model, including a continuous liquid field and two to three gas fields representing bubbles of different sizes, were first tested for numerical convergence and then validated against experimental data from the TOPFLOW and MT-Loop facilities.

This dramatic period in the history of the planet is recorded in layers carbonate termed carbonate layers that overlap directly diamictic glaciers. In this work one Neoproterozoic cap carbonate 20 m thick was Tangara described in Limestone mine, Tangara da Serra, Mato Grosso. That sequence comprises the Mirassol d West formations (dolomite) and Guide (limestone) belonging to the lower group macaws. The cover is composed of dolomitic dolograinstones peloidais pink with inverse grading, a parallel lamination and truncation of low angle, in addition to discontinuous layers of fibrous crystals calcite (gypsum pseudomorphs second?), interpreted as records of a shallow to moderately deep platform with hypersalinity events. The cover Limestone consists of rolled and massive, siltstone rich in iron oxide, and lime thin with wavy bedding megamarcas interpreted as deposits moderately deep mixed platform dominated by waves. Limestone with fine corrugated laminating / ripple marks and fans crystals (pseudomorphs second aragonite), intercalated with shales were interpreted as deposits deep platform and supersaturated in CaCO3. With calcareous structures Slip including convoluted laminations and syn-sedimentary faults characterized slope deposits, while Neptunian dykes, filled with limestone breccias, and deformed layers between non deformed layers suggest seismic activity. Three stratigraphic surfaces divide the carbonate succession studied: S1 separates the covers dolomitica and limestone and is interpreted as transgressive surface, while surfaces S2 and S3 within the limestone cover are considered limits facies. Facies deformed occur throughout the sequence, separated by intervals without strain, and were split into three packages (A, B and C). Packages A and C exhibit ductile-brittle structures like folds, faults and bedding convoluted, while the B package contains structures formed in brittle regime as failures and fractures. Analysis of C and O isotopes showed negative values ​​similar to found in other carbonate covers the world. The data 13C isotope values ​​between -4 and -6 in the case dolomite , limestone while in the case 13C the values ​​reaches to -7 without co- variance of the 18 O isotope indicates change by meteoric fluids or by dolomitization . The sequence described in Tangara Sierra expands the occurrence of carbonate layers in South America and corroborates the interpretation of an extensive carbonate platform post- glaciation Puga , related to Marinoano event , this part of the Amazon Craton. / O Neoproterozóico é marcado por importantes mudanças climáticas que interferiram da forma crucial na evolução biológica e paleoceanográfica do nosso planeta, sendo caracterizado principalmente por períodos de glaciação global que alcançaram baixas latitudes. Este período dramático da história do planeta está registrado em camadas carbonáticas denominadas de capas carbonáticas que sobrepõem diretamente diamictitos glaciais. Neste trabalho uma capa carbonática neoproterozóica de 20 m de espessura foi descrita na mina Calcário Tangará, região de Tangará da Serra, Mato Grosso. Essa seqüência compreende as formações Mirassol d Oeste (dolomítica) e Guia (calcária) que pertencem à parte inferior do Grupo Araras. A capa dolomítica é composta por dolograinstones peloidais rosados com gradação inversa, laminação plano-paralela e truncamentos de baixo ângulo, alem de camadas descontínuas de cristais fibrosos de calcita (pseudomorfos segundo gipsita?), interpretados como registros de uma plataforma rasa a moderadamente profunda com eventos de hipersalinidade. A capa calcária consiste em siltitos laminados e maciços, ricos em óxido de ferro e calcários finos com acamamento de megamarcas onduladas, interpretados como depósitos de plataforma mista moderadamente profunda dominada por ondas. Calcários finos com laminação ondulada/marcas onduladas e leques de cristais (pseudomorfos segundo aragonita), intercalados com folhelhos, foram interpretados como depósitos de plataforma profunda e supersaturada em CaCO3. Calcários com estruturas de escorregamento incluindo laminações convolutas e falhas sin-sedimentares caracterizam depósitos de talude, enquanto diques neptunianos, preenchidos por brechas calcárias, e camadas deformadas entre camadas não deformadas sugerem atividade sísmica. Três superfícies estratigráficas dividem a sucessão carbonática estudada: S1 separa as capas dolomitica e calcária e é interpretada como superfície transgressiva, enquanto as superfícies S2 e S3, dentro da capa calcária são consideradas limites de fácies. Fácies deformadas ocorrem ao longo de toda a sucessão, separadas por intervalos sem deformação, e foram subdivididas em três pacotes (A, B e C). Os pacotes A e C apresentam estruturas dúctil-rúptil como dobras, falhas e acamamento convoluto, enquanto o pacote B contém estruturas formadas em regime rúptil como falhas e fraturas. A análise de isótopos de C e O mostrou valores negativos semelhantes aos encontrados em outras capas carbonáticas pelo mundo. Os dados de isótopos de 13C apresentam valores entre -4 e -6 na capa dolomítica, enquanto que na capa calcária os valores de 13C alcançam até -7 sem co-variância dos isótopos de 18O, indica alteração por fluidos meteóricos ou pela dolomitização. A sucessão descrita em Tangará da Serra amplia a ocorrência de capas carbonáticas na América do Sul e corrobora com a interpretação de uma extensa plataforma carbonática pós-glaciação Puga, correlata ao evento Marinoano, nesta parte do Cráton Amazônico.

Many aspects of Ignaz Jan Paderewski’s life and career have been the subject of previous research, but some important areas remain uninvestigated. Moreover, many biographies, especially those written in English, have hitherto rarely adopted a critical stance. My aim here is to examine those elements of Paderewski’s performance style that have not hitherto been fully studied. Unique Polish sources include unpublished letters written to his father and Helena Górska, his secretaries’ letters written in 1935 and between 1938-39, and of course his correspondence with his pupils, which sheds considerable new light on his views on, and success in, piano teaching. This dissertation discusses in detail his stylistic approach, attitude towards piano playing, preparation for performance and methods of interpretation. Unpublished letters between Paderewski and his pupils deal with such issues as: choosing concert programmes, techniques of pedalling and advanced interpretational issues. To further evaluate changes in Paderewski’s playing style over his career I have analysed a representative selection of his recordings made over the course of his career. Although Paderewski’s style did not change radically, some of the recorded pieces do demonstrate significant differences in interpretation, and his experiments in phrasing, dynamics, tempo and pedaling. I additionally compare some of the recordings of the same pieces by Paderewski and his contemporaries. For instance, Arthur Friedheim’s recording of Liszt’s Hungarian Rhapsody No. 2 in C sharp minor. An approach such as this will illuminate, for example, some differences in style between representatives of the ‘Liszt School’ (of which Friedheim was one of the most celebrated exponents) and that of Leschetizky (as represented by Paderewski). This documentation and evaluation of Paderewski’s performance style has naturally influenced my own performances of his works. The accompanying recital therefore includes one of Paderewski’s most substantial piano pieces, the Sonata in E flat minor, contrasted by a Sonata by Paderewski’s contemporary, Sergei Rachmaninov, and completed by works of Chopin in Paderewski’s repertoire, and a piece by his pupil, Ernest Schelling, also recorded by Paderewski. The recital therefore constitutes a practical application of Paderewski’s performance and programming styles as discussed in the dissertation.

This thesis examines the present practice of Odissi, the classical dance form of Orissa in Eastern India, with the view to identifying its strengths as a performing art and building on them. The objectives were to share this dance tradition both on stage and in the studio, not just as a stylised Indian movement form of limited interest, but as an integrating dance experience of relevance to today's multicultural world. The primary concern has been determining parallels with yoga and ritual and addressing the question of transcendence through dance, as understood in the Indian tradition. A choreological perspective has been adopted for this study and Odissi viewed from the position of the student, performer, choreographer, teacher and audience member, all roles which this researcher has performed personally. The basic parameters of Odissi's movement and dance techniques have been analysed informed by this discipline. Odissi has been reviewed historically, both when it was a medieval temple ritual and more recently when it was reconstructed as a classical Indian art after the country's Independence. The hypothesis that the practice of this dance was unconsciously governed by a bedrock of tantric thought forming its covert structures has been explored. Choreographic works have been created in collaboration with traditional musicians using established forms of composition to explain working methods within the tradition and experience its limitations. An alternate way of embodying Odissi based on tantric practices has been outlined. Works that explore this and that stretch the traditional sound-movement nexus of this dance form in the process, have also been created. The results of this research project hence fall broadly into the following inter-related areas: an understanding of Odissi dance and movement in relation to its culture and society; a hypothesis about the phenomenological nature of the medieval Orissan temple dance ritual; an outline of an alternate way of practicing Odissi based on tantric principles; and a choreological documentation of compositions created that make the practice of dance a form of yoga as defined by the Indian tradition.

The aim of this project was to explore whether voice care and development, prior to qualification, could mitigate potential vocal attrition in newly qualified teachers/lecturers within their first year of teaching. A specific focus of the research was to see if any causative relationship could be seen to exist between vocal change, specifically change in vocal quality, and the exigencies of the teaching role. Vocal quality in this instance is defined as the way in which individual voices demonstrate discrete features of pitch, resonance, degree of breathiness and clarity of the note. The sum of these features is perceived as voice/vocal quality. The study sought to gain a deeper knowledge of the vocal demands of the teaching role with a particular focus on the experiences of newly qualified teachers and lecturers. It was hoped, that information gained as a result of the study, would add to the current canon of knowledge regarding the vocal demands on teachers as a feature of their professional role. As a result of the study a number of important elements were identified, some of which go beyond the original focus of the research but arise from data gathered doing it. A number of recommendations are made which, it is hoped, will inform future working practice and increase vocal health within the teaching profession.

This study focuses on exocontact mineral assemblages to determine composition, thermal signatures, and the extent of exomorphism that occurred between the Mt. Mica pegmatite and the migmatite host rock at the contact. Biotite-garnet thermometry of country rock samples resulted in an average temperature estimate of 630 °C. Measured biotite Fe/(Fe+Mg) ratios were used to calculate an fO2 of -18. The results indicate that the country rock and pegmatite formed under similar oxidizing conditions near the quartz-fayalite-magnetite (QFM) equilibria buffer. Whole rock (REE) analysis indicates an interaction trend between the country rock and pegmatite. Exomorphism does not appear to have been significant at Mt. Mica, likely due to the moderately evolved nature of the pegmatite. Minor B leakage into the surrounding country rock is constrained to within 15 cm from the contact. Results indicate no enrichment of alkali elements (Li, Rb, Cs), As, U, or F occurred in minerals analyzed.
