As an alternative to existing research which states that the phenomenon of displacement resists theorisation because of its complex nature, this study conducts a Phenomenological examination of the nature of displacement in which the interlinked losses in the key concepts of the consciousness of the displaced, namely Memory, Land and home and Identity, are navigated. It is shown that the current consciousness of society mimics these losses with the effect of displacement being experienced as a state of mind by contemporary society. By comparing selected artworks of artists Rachel Whiteread and Cornelia Parker, it is established that although manifested in diverse ways, contemporary artworks reflect displacement according to a set of broadly defined visual signifiers. The visual documentation of a site of displacement in the North West Province of South Africa and subsequently produced artworks underline these findings and highlight the elusive attributes of loss inherent in the displacement phenomenon. / Art History, Visual Arts and Musicology / M.A. (Visual Arts)

Cette thèse porte sur la fonctionnalisation de surface par microstructuration laser. L’étude expérimentale a consisté à texturer des surfaces d’acier inoxydable avec une source laser impulsionnelle à fibre dopée Yb (1030 nm, 300 fs), dans le but de contrôler leur mouillabilité et de les rendre superhydrophobes. Par une optimisation des conditions d’irradiation, il est possible de conférer à la surface une structuration à double échelle de rugosité. Des structures d’une dizaine de micromètres sont réalisées par ablations successives selon un motif de lignes croisées, sur lesquelles se forment des nanostructures auto-organisées. La simulation du couplage de l’énergie dans la cible a permis de déterminer les paramètres opératoires pour limiter l’accumulation thermique en surface. L’étude fait clairement apparaître le rôle de la texturation dans l’apparition du caractère superhydrophobe de la surface, tout en soulignant l’influence des propriétés physico-chimiques du matériau. / This PhD thesis is about surface functionalization by laser microstructuring. The experimental study consists in texturing stainless steel surfaces with a pulsed Yb fibre laser source (1030 nm, 300 fs), in order to control their wettability and confer to them superhydrophobic properties. With an optimization of the irradiating conditions on the target, it is possible to confer to the surface a dual-scale roughness. By successive ablations according to a pattern of crossed lines, microstructures in the range of tens of micrometres are realized, on which self-organized nanostructures are superimposed. Simulation of the energy coupling in the material allows to determine the process parameters to be used, in order to limit the thermal accumulation and avoid the melting of the surface. This study reveals the role of the laser texturing in the apparition of the superhydrophobic character and emphasizes the influence of the physicochemical properties of the material.

Cette thèse traite du contrôle et de la caractérisation de l'alignement et de l'orientation du point de vue théorique et expérimental. L'alignement d'une molécule linéaire consiste à obtenir une probabilité élevée de localisation de l'axe internucléaire symétrique autour de l'axe de polarisation du champ tandis que l'orientation privilégie un sens particulier le long du champ. L'orientation à l'aide d'impulsions bi couleur (2+1) non résonnantes est étudiée en détail et les conditions permettant d'obtenir une orientation efficace sont examinées. Un schéma bi couleur où la deuxième harmonique est en quasi-résonance avec un niveau vibrationnel de la molécule est également étudié. Cette technique présente l'avantage d'offrir un paramètre supplémentaire à savoir l'écart à la résonance qui peut être ajusté de manière à optimiser l'orientation moléculaire. Finalement une nouvelle technique expérimentale de détection de l'alignement moléculaire est présentée. Celle-ci permet une détection monocoup de l'alignement moléculaire sur une étendue temporelle jusqu'alors inégalée. / This thesis is about the control and characterisation of the alignment and orientation of molecules by ultra short laser pulses on a theoretical and experimental approach. Alignment corresponds to a symmetric angular distribution of the molecular axis peaked along the laser field axis, whereas orientation provides an asymmetric distribution favouring one spatial direction. Orientation by sudden two-colour (2+1) pulses is studied extensively for the non resonant case and conditions required for achieving significant orientation are explored. A second two-colour scheme, where the second harmonic is in quasi resonance with a vibrational level of the molecule, is also presented and discussed. The last technique has the advantage to offer the detuning of the laser frequency as an additional free parameter, which can be adjusted to enhance molecular orientation. A new experimental polarization imaging 2D technique for the detection alignment is also developed. Experimental results on single shot detection of molecular alignment achieved over an unprecedented temporal span are presented.

Olivier Messiaen is regarded as one of the most significant composers of the 20th century. His compositions are performed regularly and his teachings have influenced many well-known composers like Boulez and Stockhausen. This study focussed on his use of rhythm in his piano compositions. I supplied a short biography of the composer along with a brief discussion of his compositional techniques. Thereafter his rhythmic techniques were examined through relevant music examples from his piano repertoire. Particular attention was given to works from the Vingt Regards sur L’Enfant-Jésus along with Cantéyodjayâ, Mode de valeurs et d’intensités and Neumes rythmiques from his experimental period (1949-1951). In Mode de valeurs et d’intensités he revolutionized the serial treatment of duration, pitch, intensity and attack. His other rhythmic techniques include Indian rhythms, Greek meter, added values, augmentation, diminution, non-retrogradable rhythms, polyrhythm, chromatic scales of duration, personnages rythmiques, symmetrical permutations, rhythmic neumes, rhythmic canon and prime numbers. / Dissertation (MMus (Performing Arts))--University of Pretoria, 2008. / Music / unrestricted

In this study a linguistic investigation of the traditional colour terms of Northern Sotho was carried out. The research comprised three separate phases. In all three phases two aspects were emphasised, namely, the nature of the concept underlying each colour term and the nature and extent to which the selection requirements of the term affected the antecedent. In the first phase, the definitions of selected colour terms, as given in three standard Northern Sotho dictionaries, were studied and compared. These dictionaries included: Pukuntšu, The New Sesotho Dictionary and the Groot Noord-Sotho Woordeboek. Special reference was made to (a) the description of colour as given in the definition, and (b) the selection requirements with regard to the antecedent. The concept “colour term” itself is problematic as the definitions of these terms encompass more than mere references to colour. When comparing the definitions of these terms in Northern Sotho dictionaries, however, little unanimity could be found regarding: (a) the the concept underlying the colour terms, and (b) the selection requirements of these terms in respect of the antecedent. In phase two, six mother-tongue speakers of Northern Sotho were interviewed. The descriptions of the colour terms provided by these respondents were then analysed in the same manner as that of the dictionaries. The informants were all professional people with notable linguistic ability and knowledge of livestock. An Electronic Data Base (compiled by the Department of African Languages, University of Pretoria) was consulted in the third phase of study. The objective of this phase was to collect data on the frequency of use of these colour terms and in light of this to make deductions on their selection requirements. Finally, a synthesis was made of the information collected during the three phases. As indicated above, this is a practical study falling within the ambit of the science of language-usage. At most it can be claimed that the conceptualisation of colour and the manner in which it is reflected in language, has a psycho-linguistic basis. As a result of the nature of the study, it could not always be carried out within a strict theoretical framework. / Dissertation (M A (African Languages))--University of Pretoria, 2005. / African Languages / unrestricted

This diploma thesis is focused on the study of the influence of advanced oxidation processes on degradation of organic dyes. The field of AOP – very effective physically-chemical methods of wastewater treatment – includes application of strong oxidation agents, UV and ionizing radiation and electrical discharges. For this thesis, two of these methods were chosen – the application of oxidation agent (ozone) and UV radiation. Along with electrolysis, which is mentioned rather marginally in this thesis (it is the subject of the previous thesis), these phenomena are products of electrical discharge in water, where they participate in the processes of degradation in a different way. For all measurement series, two direct azo dyes were chosen as model substances – C.I. Direct Blue 106 and C.I. Direct Red 79. The ozonizer, in which either oxygen or synthetic or technical air were loaded as carrier gases, was used for degradation of dyes by ozone. The generated ozone was loaded into the bubbling vessel with dye solution of different initial concentration (10–130 mg.dm-3), which was followed by other bubbling vessel with KI solution for the next analytical determination of the amount of generated ozone. The other parameters changed were the gas flow (1–2 dm3.min-1), ozonizer output (minimal and maximal), type of dye, pH value of the solution (neutral or acid) and additional electrolyte (NaCl, Na2SO4 or any). The reactor for the study of the influence of UV radiation on degradation of dyes was an UV sterilizer into which the equivalent volume of dye solution was added. The possibilities of experimental settings were limited and only the type of dye, an additional electrolyte and pH value of the dye solution were adjusted (as in the case of ozone). Several series of samples were measured with various input conditions which more or less influenced the degradation of investigated dyes in this experiment. It was found that for both used methods the Direct Blue 106 dye was more degradable (with significantly better results for ozone than for UV radiation). The degradation of Direct Red 79 dye proceeded only by ozone treatment, in the case of the application of UV radiation no degradation occurred. By investigation of the influence of initial concentration of dye on its degradation, it was confirmed that with the initial concentration enhancement the final concentration rises as well, whereas in low concentrations (10–50 mg.dm-3) the initial concentration has no effect. The addition of an electrolyte had an accelerating effect on dye degradation in both methods (NaCl and also Na2SO4 showed similar results though the degradation proceeded in different ways). The addition of HCl accelerated the degradation only in the case of UV radiation; during the application of ozone the pH level of the system did not have any influence on the degradation. Oxygen and synthetic air had the strongest effect on ozone degradation (comparable results); in the case of technical air the final dye concentration was higher up to 30 %. The gas flow of 1.5 dm3.min-1 was stated as optimal with the ozonizer output 30 W (maximal). At minimal power the ozonizer produced very low amount of ozone.

Die Arbeit prüft, inwieweit die Übersetzungstheorien von Otto Kade et al., Werner Koller und die Skopostheorie das Problem der kulturgebundenen Farbwortvielfalt bei der Übersetzung zu lösen versuchen. Im ersten Teil wird hierfür der Grundstein gelegt, indem interdisziplinäres Wissen auf die Bildung von Farbbezeichnungen, ihrer Herkunft und ihrer biologischen und physikalischen Grundsätze angewendet wird. In diesem Zusammenhang wird auch die Sapir-Whorf-Hypothese diskutiert. Die Etymologie bestehender Farbbezeichnungen verschiedenster Sprachen bildet dabei das Zentrum, sowohl für die Erklärung der Farbwahrnehmung und die Kulturgebundenheit ihrer Bezeichnungen als auch der Neuschöpfung von Farbbezeichnungen in den Übersetzungssituationen. Anhand fiktiver Übersetzungssituationen aus dem Alltag wird der Übersetzungsprozess für jede Übersetzungstheorie simuliert und aus ihrer Sicht verfolgt.

Wetland sites provide important knowledge about settlement history and historical infrastructure in the form of buried archaeological features. However, the subsurface is difficult to access, e.g. due to high groundwater levels or unstable sediments, making archaeological excavation difficult and the conservation of recovered artefacts, e.g. timbers, is expensive. In addition, one of the aims of heritage conservation is to disturb structures in such contexts as little as possible as part of preserving. Therefore, alternative non- and minimal-invasive methods, e.g. geophysical prospection and vibra-coring, are used for exploration. However, geophysical surveys face the issue of inaccurate depth values and rely on sufficient contrasts in the measured physical parameters. Vibra-coring allows direct access to the sediments, but again gives inaccurate depth values due to high compaction rates. For this reason, the implementation of alternative methods and the development of new methodical approaches to wetland site exploration are of extraordinary importance. One such wetland site is the Fossa Carolina, an early medieval canal that today is partially buried. Located in Southern Germany next to Treuchtlingen, south of Nuremberg, the canal was intended at the time to provide a navigable link between the Rhine-Main and Danube basins by bridging the European watershed. In the research for this thesis, direct push sensing was used as an alternative exploration technique to explore the site. In this method, various probes are pushed into the unconsolidated subsoil and the parameters are measured in situ with high depth accuracy. (i) Therefore, the colour logging tool (CLT) and the electrical conductivity (EC) probe were applied. (ii) In order to record archaeological structures and features, the soundings were distributed closely along a transect using an adaptive exploration strategy, thus recording a high-resolution cross-section of the structure. (iii) These prospections were integrated into a spatial-hierarchical multi-method approach by combining direct push sensing with geophysical survey and vibra-coring, inter alia. (iv) Thus, a deeply buried section of the Fossa Carolina (West-East Section) was explored, demonstrating at least one-way navigability and revealing the backfill stratigraphy. (v) Furthermore, the approach used helped to clarify the nature of conspicuous magnetic anomalies in the area adjacent to the canal. In the Northern and North-Eastern Sections, magnetic anomalies provided evidence of water-supplying structures. The exploration of these structures revealed an Early Holocene structure in the North-Eastern Section and a historic gravel road in the Northern Section. (vi) Additionally, a strong magnetic anomaly with a course parallel to the canal in the Northern Section could be temporally and stratigraphically associated with the construction of the canal. Thus, for the first time, a larger remnant of the construction process outside the canal could be identified, even if the origin could not be conclusively clarified. (vii) In a broader context, the in situ direct push cross-sections were integrated into a 3D modelling approach for the entire Fossa Carolina to quantify the excavation volume. (viii) The methodological approach was successfully applied to a wetland site at Pestenacker in Southern Germany to collect evidence for Holocene floodplain dynamics in the Late Neolithic settlement. Finally, the thesis demonstrates the enormous methodological potential of direct push sensing for the exploration of buried archaeological sites. In particular, the colour logging tool is proving to be extremely effective, further enhanced by the intelligent combination in multi-method approaches. This is confirmed by the significant results obtained at Fossa Carolina that shed new light on the canal{'}s navigability, water supply, and construction structure. Overall, this thesis demonstrates the valuable contribution that direct push methods can make to geoarchaeological research. It both introduces a new methodological approach and provides new empirical evidence concerning the construction of an example of early medieval infrastructure.:Preface Acknowledgements Abstract Kurzfassung Contents List of Figures List of Tables Acronyms and Symbols 1 Introduction 1.1 Geoarchaeological exploration in wetlands: possibilities and challenges 1.1.1 Proven exploration methods 1.1.2 Direct push sensing 1.1.3 Exploration strategies 1.2 The study site 1.2.1 The Fossa Carolina - State of the art in brief 1.2.2 Natural settings 1.3 Aims of the thesis 2 Published Studies 2.1 Minimalinvasive Direct-push-Erkundung in der Feuchtboden(geo)archäologie am Beispiel des Karlsgrabens (Fossa Carolina) 2.2 Non-invasive prospection techniques and direct push sensing as high-resolution validation tools in wetland geoarchaeology – Artificial water supply at a Carolingian canal in South Germany? 2.3 High-Resolution Direct Push Sensing in Wetland Geoarchaeology—First Traces of Off-Site Construction Activities at the Fossa Carolina 2.4 3D-Modelling of Charlemagne’s Summit Canal (Southern Germany)—Merging Remote Sensing and Geoarchaeological Subsurface Data 2.5 A hydrological tipping point and onset of Neolithic wetland occupation in Pestenacker (Lech catchment, S Germany) 3 Discussion 3.1 Direct push sensing for wetland exploration 3.1.1 High-resolution direct push sensing cross-sections 3.1.2 Integration and comparison of direct push sensing in a spatially hierarchical multi-method approach 3.1.3 Direct push colour logging tool (CLT) data for ground truthing 3.1.4 Perspectives on direct push sensing in geoarchaeology 3.2 Results of the exploration of the Fossa Carolina 3.2.1 Chronostratigraphic recording in the West-East and Northern Sections 3.2.2 Characteristics of the canal construction in the West-East and Northern Sections 3.2.3 Validation of off-canal structures in the Northern and North-Eastern Sections 3.2.4 Water supply for the Fossa Carolina 3.2.5 Pending issues in the study of the Fossa Carolina 4 Conclusion References Appendix A1 - Author publications A2 - Article contribution A3 - Declaration of originality A4 - Bibliographic description / Feuchtgebiete bergen durch begrabene archäologische Strukturen wichtige Erkenntnisse zur Siedlungsgeschichte und historischen Infrastruktur. Schwierige Untergrundverhältnisse, z. B. durch hohen Grundwasserspiegel oder instabile Sedimente, erschweren jedoch archäologische Ausgrabungen und die Konservierung der geborgenen Artefakte, z. B. Hölzer, verursacht hohe Kosten. Darüber hinaus ist ein Ziel der Bodendenkmalpflege, archäologische Strukturen so wenig wie möglich zu beeinträchtigen und sie in situ zu erhalten. Daher werden alternative nicht- und minimal-invasive Methoden, z. B. geophysikalische Prospektionen und Rammkernsondierungen, zur Exploration eingesetzt. Bei geophysikalischen Untersuchungen ergeben sich jedoch Schwierigkeiten durch ungenaue Tiefenwerte und die Methoden sind auf ausreichende Kontraste der gemessenen physikalischen Parameter angewiesen. Rammkernsondierungen ermöglichen einen direkten Zugriff auf die Sedimente, erzeugen jedoch wiederum ungenaue Tiefenwerte durch hohe Kompaktionsraten. Aus diesem Grund sind die Implementierung alternativer Methoden und die Entwicklung neuer methodischer Ansätze für die Erforschung von Feuchtgebietsstandorten von herausragender Bedeutung. Die Fossa Carolina, ein frühmittelalterlicher, heute teilweise verschütteter Kanal, ist ein solcher Standort. Das Bauwerk befindet sich in Süddeutschland in der Nähe von Treuchtlingen, südlich von Nürnberg und sollte eine schiffbare Verbindung zwischen dem Rhein-Main- und dem Donaueinzugsgebiet herstellen, indem es die europäische Hauptwasserscheide überbrückte. Zur Erkundung des Bauwerks wurde als Alternative die in situ Direct-Push-Methode eingesetzt. Bei dieser Methode werden verschiedene Sonden in den unkonsolidierten Untergrund gedrückt und die Parameter in situ tiefengenau gemessen. (i) Dabei kamen die Farbsonde, engl. colour logging tool (CLT), und die Sonde zur Messung der elektrischen Leitfähigkeit, engl. electrical conductivity (EC) probe, zum Einsatz. (ii) Zur Erfassung archäologischer Strukturen und Befunde wurden die Sondierungen mit einer adaptiven Erkundungsstrategie auf einem Transekt engmaschig verteilt und somit ein hochaufgelöster Querschnitt des Bauwerks erfasst. (iii) Darüber hinaus wurden diese Prospektionen in einen räumlich-hierarchischen Multimethodenansatz integriert, indem in situ Direct-Push-Sondierungen mit z. B. geophysikalischen Erkundungen und Rammkernsondierungen kombiniert wurden. Somit wurde (iv) ein tiefliegender, begrabener Abschnitt der Fossa Carolina im West-Ost-Bereich erkundet, dort die Schiffbarkeit für mindestens eine Schiffsbreite nachgewiesen und die Sedimentstratigraphie der Verfüllung beschrieben. Weiterhin wurde der Ansatz genutzt, um magnetische Anomalien im Umfeld des Kanals zu prospektieren. (v) Im nördlichen und nordöstlichen Bereich lieferten magnetische Anomalien Hinweise auf wasserzuführende Bauwerke im Untergrund. Die Erkundung ergab eine frühholozäne Struktur im nordöstlichen Bereich und eine historische Schotterstraße im nördlichen Bereich. (vi) Weiterhin konnte eine starke magnetische Anomalie mit parallelem Verlauf zum Kanal im nördlichen Bereich zeitlich und stratigraphisch dem Bauwerk zugeordnet werden. Somit konnte zum ersten Mal eine größere Spur des Baus außerhalb des Kanals nachgewiesen werden, auch wenn die Entstehung nicht abschließend geklärt werden konnte. (vii) Im übergeordneten Kontext konnten die Daten der in situ Direct-Push-Transekte in einen 3D-Modellierungsansatz für die gesamte Fossa Carolina zur Quantifizierung des Aushubs integriert werden. (viii) Neben der Erforschung der Fossa Carolina wurde der methodische Ansatz zusätzlich an einem Feuchtgebietsstandort bei Pestenacker in Süddeutschland angewendet, um Informationen über die holozäne Auendynamik an der spätneolithischen Siedlung zu gewinnen. Schlussendlich belegt die Dissertation das enorme methodische Potential der in situ Direct-Push-Erkundungen für die Prospektion von Bodendenkmälern. Dabei erweist sich insbesondere die Farbsonde als äußerst wirkungsvoll, was durch die gezielte Kombination in multi-methodischen Ansätzen noch verstärkt wird. Dies wird durch die aussagekräftigen Ergebnisse an der Fossa Carolina belegt, mit deren Hilfe insbesondere neue Erkenntnisse zur Schiffbarkeit, Wasserzuführung und Baustruktur gewonnen werden konnten. Insgesamt demonstriert diese Dissertation den wertvollen Beitrag, den in situ Direct-Push-Methoden zur geoarchäologischen Forschung leisten können. Sie präsentiert sowohl einen neuen methodischen Ansatz als auch neue empirische Erkenntnisse zu einem frühmittelalterlichen Bauwerk.:Preface Acknowledgements Abstract Kurzfassung Contents List of Figures List of Tables Acronyms and Symbols 1 Introduction 1.1 Geoarchaeological exploration in wetlands: possibilities and challenges 1.1.1 Proven exploration methods 1.1.2 Direct push sensing 1.1.3 Exploration strategies 1.2 The study site 1.2.1 The Fossa Carolina - State of the art in brief 1.2.2 Natural settings 1.3 Aims of the thesis 2 Published Studies 2.1 Minimalinvasive Direct-push-Erkundung in der Feuchtboden(geo)archäologie am Beispiel des Karlsgrabens (Fossa Carolina) 2.2 Non-invasive prospection techniques and direct push sensing as high-resolution validation tools in wetland geoarchaeology – Artificial water supply at a Carolingian canal in South Germany? 2.3 High-Resolution Direct Push Sensing in Wetland Geoarchaeology—First Traces of Off-Site Construction Activities at the Fossa Carolina 2.4 3D-Modelling of Charlemagne’s Summit Canal (Southern Germany)—Merging Remote Sensing and Geoarchaeological Subsurface Data 2.5 A hydrological tipping point and onset of Neolithic wetland occupation in Pestenacker (Lech catchment, S Germany) 3 Discussion 3.1 Direct push sensing for wetland exploration 3.1.1 High-resolution direct push sensing cross-sections 3.1.2 Integration and comparison of direct push sensing in a spatially hierarchical multi-method approach 3.1.3 Direct push colour logging tool (CLT) data for ground truthing 3.1.4 Perspectives on direct push sensing in geoarchaeology 3.2 Results of the exploration of the Fossa Carolina 3.2.1 Chronostratigraphic recording in the West-East and Northern Sections 3.2.2 Characteristics of the canal construction in the West-East and Northern Sections 3.2.3 Validation of off-canal structures in the Northern and North-Eastern Sections 3.2.4 Water supply for the Fossa Carolina 3.2.5 Pending issues in the study of the Fossa Carolina 4 Conclusion References Appendix A1 - Author publications A2 - Article contribution A3 - Declaration of originality A4 - Bibliographic description
