Thesis (PhD)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: The synthesis of a range of siloxane functionalized Ru(arene)Cl(N,N) complexes allowing for the synthesis of novel MCM-41 and SBA-15 immobilized ruthenium(II) catalysts, is described in this thesis. Two distinctly different approaches were envisaged to achieve successful heterogenization of these siloxane functionalized complexes. Condensation of the siloxane functionalized complexes, C2.4-C2.6 (siloxane tether attached to imine nitrogen) and C3.5-C3.7 (siloxane tether via the arene ring), with the surface silanols of the synthesized silica support materials MCM-41 and SBA-15, afforded immobilized catalysts IC4.1-IC4.6 (siloxane tether attached to imine nitrogen) and IC4.7-IC4.12 (siloxane tether via the arene ring). Model and siloxane functionalized complexes C2.1-C2.6 were prepared by the reaction of diimine Schiff base ligands L2.1-L2.6 with the [Ru(p-cymene)2Cl2]2 dimer. A second, novel, approach involved the introduction of the siloxane tether on the arene ligand of the complex. Cationic arene functionalized Ru(arene)Cl(N,N) complexes, C3.1-C3.4, were prepared with varying N,N ligands including bipyridine and a range of diimine ligands, with either propyl or diisopropyl(phenyl) substituents at the imine nitrogen (greater steric bulk around the metal center). The reaction of these propanol functionalized complexes with 3-(triethoxysilyl)propyl isocyanate, afforded urethane linked siloxane functionalized complexes C3.5-C3.8, where the siloxane tether is attached to the arene ring of the complex. The complexes were fully characterized by FT-IR spectroscopy, NMR (1H and 13C) spectroscopy, ESI-MS analysis and microanalysis. Suitable crystals for the alcohol functionalized complex C3.1 were obtained and the resultant orange crystals were analyzed by single crystal XRD. The heterogenized catalysts, IC4.1-IC4.12, were characterized by smallangle powder X-ray diffraction, scanning and transmission electron microscopy (SEM and TEM), thermal gravimetric analysis (TGA), inductively coupled plasma optical emission spectroscopy (ICP-OES) and nitrogen adsorption/desorption (BET) surface analysis to name but a few. ICP-OES allowed for direct comparison of the model and immobilized systems during catalysis ensuring that the ruthenium loadings were kept constant. The application of the model complexes C2.1-C2.3 and C3.1-C3.3, as well as their immobilized counterparts, IC4.1-IC4.12, as catalyst precursors in the oxidative cleavage of alkenes (1-octene and styrene), were investigated. The proposed active species for the cleavage reactions was confirmed to be RuO4 (UV-Vis spectroscopy). In general it was observed that at lower conversions, aldehyde was formed as the major product. Increased reaction times resulted in the conversion of the formed aldehyde to the corresponding carboxylic acid. For the oxidative cleavage of 1-octene using the systems with the siloxane tether attached to the imine nitrogen, the immobilized systems outperformed the model systems in all regards. Higher conversions and selectivities of 1-octene towards heptaldehyde were obtained when using immobilized catalysts IC4.1-IC4.6, as compared to their non-immobilized model counterparts (C2.1-C2.3) at similar times. It was found that the immobilized catalysts could be used at ruthenium loadings as low as 0.05 mol %, compared to the model systems where 0.5 mol % ruthenium was required to give favorable results. Complete conversion of 1-octene could be achieved at almost half the time needed when using the model systems as catalyst precursors. The activity of the model systems seems to increase with the increase in steric bulk around the metal center. These model and immobilized systems were also found to cleave styrene affording benzaldehyde in almost quantitative yield in some case (shorter reaction times). The systems, with the siloxane tether via the arene ring, were found to be less active for the cleavage of 1-octene when compared to the above mentioned systems (siloxane tether attached to the imine nitrogen). The immobilized systems IC4.7-IC4.12 performed well compared to their model counterparts, but could not achieve the same conversions at the shorter reaction times as were the case for IC4.1-IC4.6. This lower activity was ascribed to the decreased stability of these systems in solution compared to the above mentioned systems with the tether attached to the imine nitrogen. This was confirmed by monitoring the conversion of the complex (catalyst precursor) to the active species in the absence of substrate (monitored by UV-Vis spectroscopy). It was observed that model complex C3.1 could not be detected in solution after 1 hour, compared to complex C2.2 which was detected in solution even after 24 hours. Experiments were carried out where MCM-41 was added to a solution of model complex C2.2 under typical cleavage reaction conditions. A dramatic increase in the conversion was achieved when compared to a reaction in the absence of MCM-41. An investigation into the effect of the support material on the formation of the expected active species was carried out using UV-Vis spectroscopy. The presence of the active species, RuO4, could be observed at shorter reaction times in the presence of MCM-41. This suggested that the silica support facilitates the formation of the active species from the complex during the reaction, therefore resulting in an increased activity. It was also observed that RuO4 is present in solution in reactions where the immobilized catalyst systems are used after very short reaction times, compared to the prolonged times required for this to occur as is the case for the model systems. Model and immobilized catalysts, C2.1-C2.3 and IC4.1-IC4.6, were also applied as catalysts for the transfer hydrogenation of various ketones. The immobilized systems could be recovered and reused for three consecutive runs before the catalysts became inactive (transfer hydrogenation of acetophenone). Moderate to good conversion were obtained using the immobilized systems, but were found to be less active their model counterparts C2.1-C2.3. / AFRIKAANSE OPSOMMING: Die sintese van `n reeks siloksaan gefunksioneerde Ru(areen)Cl(N,N) komplekse, wat die sintese van nuwe MCM-41 en SBA-15 geimmobiliseerede rutenium(II) katalisatore toelaat, word in hierdie tesis beskryf. Twee ooglopend verskillende metodes is voorgestel om die suksesvolle immobilisering van die siloksaan gefunksioneerde komplekse te bereik. Die kondensasie van die siloksaan gefunksioneerde komplekse, C2.4-C2.6 (siloksaan ketting geheg aan die imien stikstof) en C3.5-C3.7 (siloksaan ketting geheg aan die areen ligand), met die oppervlak silanol groepe van die silika materiale MCM-41 en SBA-15, laat die sintese van geimmobiliseerde katalisatore IC4.1-IC4.6 (siloksaan ketting geheg aan die imien stikstof) en IC4.7-IC4.12 (siloksaan ketting geheg aan die areen ligand) toe. Model en siloksaan gefunksioneerde komplekse C2.6-C2.6 is berei deur die reaksie tussen Schiff basis ligande, L2.1-L2.6, en die [Ru(p-simeen)2Cl2]2 dimeer. `n Tweede, nuwe benadering wat die sintese van komplekse met die siloksaan ketting geheg aan die areen ligand behels, is ook gevolg. Kationiese areen gefunksioneerde Ru(areen)Cl(N,N) komplekse, C3.1-C3.4, is berei deur die N,N ligande rondom die metaal sentrum te wissel vanaf bipiridien tot `n reeks diimien ligande met propiel of diisopropielfeniel substituente by die imien stikstof. Hierdie propanol gefunksioneerde komplekse is met 3-(triëtoksiesiliel)propiel-isosianaat gereageer om sodoende die uretaan gekoppelde siloksaan gefunksioneerde komplekse C3.5-C3.8 op te lewer. Al die komplekse is ten volle gekaraktariseer deur van FT-IR spektroskopie, KMR (1H and 13C) spektroskopie, ESI-MS analise en mikroanalise gebruik te maak. In die geval van model kompleks C3.1, is `n kristalstruktuurbepaling ook uitgevoer. Die heterogene katalisatore, IC4.1- IC4.12, is gekaraktariseer deur poeier X-straaldiffraksie, skandeer- en transmissieelektronmikroskopie, termogravimetriese analise (TGA), induktief gekoppelde plasma optiese emissie spektroskopie (IKP-OES) en BET oppervlak analises, om net `n paar te noem. IKP-OES het ons toegelaat om `n direkte vergelyking te tref tussen die model en geimmobiliseerde sisteme tydens die katalise reaksies. Model komplekse C2.1-C2.3 en C3.1-C3.3, sowel as hul geimmobiliseerde eweknieë IC4.1- IC4.12, is vir die oksidatiewe splyting van alkene (1-okteen en stireen) getoets. Die voorgestelde aktiewe spesie wat tydens hierdie reaksie gevorm word, RuO4, is bevestig deur van UV-Vis spektroskopie gebruik te maak. Oor die algemeen is dit gevind dat aldehied oorheersend gevorm word by laer omsetting. Wanneer die reaksietyd verleng is, is daar gevind dat die aldehied na die ooreenstemmende karboksielsuur omgeskakel is. Wanneer die geimmobiliseerde katalisatore gebruik is tydens die oksidatiewe splitsing van 1-okteen, het die sisteme, met die ketting geheg aan die imien stikstof, deurgangs beter as die model sisteme gevaar. Hoër omskakelings van 1-okteen en hoë selektiwiteite vir heptaldehied is behaal wanneer die geimobiliseerded katalisatore IC4.1-IC4.6 met die nie-geimmobiliseerde model sisteme (C2.1- C2.3) vergelyk is by dieselfde reaksietye. Die geimobiliseerde sisteme kon by rutenium beladings van so laag as 0.05 mol % gebruik word. Dit is in teenstelling met die model sisteme waar 0.5 mol % rutenium nodig was om die reaksie suksesvol te laat plaasvind. Die totale omskakeling van 1-okteen is bereik in die helfte van die tyd wat nodig was wanneer die model sisteme gebruik is. Dit is gevind dat die aktiwiteit van die model sisteme toeneem met `n toename in die steriese grootte van die ligand rondom die metaal. Beide die model en geimmobilseerde sisteme kon ook gebruik word vir die oksidatiewe splyting van stireen. Bensaldehied kon in kwantitiewe opbrengs gevorm word in sommige gevalle. `n Laer aktiwiteit vir die oksidatiewe splyting van 1-okteen is vir die sisteme waar die siloksaan ketting aan die areen ligand geheg is, waargeneem. Hoewel die geimmobiliseerde sisteme IC4.7-IC4.12 beter as hul model eweknieë gevaar het, kon die aktiwiteite wat met IC4.1-IC4.6 bereik is nie geewenaar word nie. Hierdie laer aktiwiteit is toegeskryf aan die verlaagde stabiliteit van dié sisteme in oplossing in vergelyking met IC4.1-IC4.6 (ketting geheg aan die imine stikstof). Die stabiliteit van beide sisteme is getoets deur die omskakeling van die model komplekse (C2.2 en C3.1; katalise voorgangers) na die aktiewe spesie te monitor (UV-Vis spektroskopie). Na 1 uur kon die model kompleks C3.1 nie meer in die oplossing waargeneem word nie. In teenstelling kon model kompleks C2.2 nog selfs na 24 uur in die oplossing bespeur word. Om die rol van die silika materiale tydens die reaksie te ondersoek, is `n eksperiment uitgevoer waar MCM-41 by `n oplossing van kompleks C2.2 gevoeg is. `n Toename in die omskakeling van 1-okteen is waargeneem in vergelyking met `n reaksie waar geen silika teenwoordig was nie. UV-Vis spektroskopie is gebruik om die invloed van die silika op die vorming van die aktiewe spesie te ondersoek. In eksperimente waar MCM-41 teenwoordig was, kon die aktiewe spesie, RuO4, by baie korter reaksietye waargeneem word. Dit wil blyk of die silika materiaal die vorming van die aktiewe spesie vanaf die kompleks aanhelp en sodoende `n toename in die spoed van die reaksie bewerkstellig. RuO4 kon ook by baie korter reaksietye waargeneem word wanneer die geimmobiliseerde sisteme gebruik is. Beide model en geimmobiliseerde sisteme, C2.1-C2.3 en IC4.1-IC4.6, is getoets vir die oordrag hidrogenering van verskilende ketone. Dit was moontlik om die geimmobiliseerde sisteme drie keer te herwin en vir daaropvolgende reaksies te gebruik. Vir die geimmobiliseerde sisteme kon egter slegs gemiddelde omskakelings verkryg word en het swakker gevaar as hul model ekwivalente sisteme, C2.1-C2.3.

This dissertation investigates the political stakes of women’s work with sound technologies engaging the body since the 1970s by drawing on frameworks and methodologies from music history, sound studies, feminist theory, performance studies, critical theory, and the history of technology. Although the body has been one of the principal subjects of new musicology since the early 1990s, its role in electronic music is still frequently shortchanged. I argue that the way we hear electro-bodily music has been shaped by extra-musical, often male-controlled contexts. I offer a critique of the gendered and racialized foundations of terminology such as “extended,” “non-human,” and “dis/embodied,” which follows these repertories. In the work of American composers Joan La Barbara, Laurie Anderson, Wendy Carlos, Laetitia Sonami, and Pamela Z, I trace performative interventions in technoscientific paradigms of the late twentieth century. The voice is perceived as the locus of the musical body and has long been feminized in musical discourse. The first three chapters explore how this discourse is challenged by compositions featuring the processed, broadcast, and synthesized voices of women. I focus on how these works stretch the limits of traditional vocal epistemology and, in turn, engage the bodies of listeners. In the final chapter on musical performance with gesture control, I question the characterization of hand/arm gesture as a “natural” musical interface and return to the voice, now sampled and mapped onto movement. Drawing on Cyborg feminist frameworks which privilege hybridity and multiplicity, I show that the above composers audit the dominant technoscientific imaginary by constructing musical bodies that are never essentially manifested nor completely erased.

The present study aims to predict which individual factors may influence strategy-choices in wayfinding situations, specifically when participants are faced with ambiguous instructions in unfamiliar environments. Individual differences were measured with self-report forms of the Big Five personality traits and the Santa Barbara sense of direction scale (SBSOD). The study was conducted in a web-based survey format with a n=104 (65 female, and 39 male). A regression analysis concluded that the trait conscientiousness was the only factor that had predictive value in determining choice of strategy. SBSOD had some predictive values towards strategy-choice, but needs further investigation before any general conclusion can be drawn. Future studies should focus on a more goal‑oriented task with more realistic stimulus.

Traditional readings of George Bernard Shaw's texts suggest that he is not a pure Marxist socialist because of the spiritual and nationalist aspects of his vision. This thesis attempts to confront Shaw's politics in order to demonstrate that he indeed offers a viable socialist program. Overlaying his socialism with Louis Althusser's concepts of "overdetermination," "structural causality," and "ideology" reveals that Shaw uses relatively autonomous instances of the superstructure toward socialist ends. This reevaluation of Shaw is best achieved through a combined reading of three of his major plays -- John Bull's Other Island, Man and Superman, and Major Barbara. In John Bull, Shaw incorporates the controversy of nationalism into his socialist vision by explaining it as an inevitable step in the development of an oppressed nation toward socialism. Man and Superman discusses the need for spirituality in the form of Shaw's concepts of Creative Evolution and the Life Force, which drive toward the development of a consciousness that recognizes socialism as the only sustainable internationalist program. Major Barbara combines Shaw's socialist and spiritual views by showing that both stand in reciprocal relation to each other; they are equally necessary to the Shavian world, one providing the ideal social system, the other the most enlightened human sensibility. This project demonstrates that Shaw's integration of these elements usually considered contradictory to Marxism becomes a way to understand him as practicing the Althusserian idea that any displacements of the infrastructure are economic in the last instance. / Graduation date: 1999

L'érosion hydrique est un phénomène complexe, largement répandu en Afrique du Nord, notamment dans la chaine montagneuse de la Kroumirie (Nord ouest de la Tunisie) où les facteurs influençant ce fléau expriment bien la fragilité du milieu qui se métamorphose graduellement vers le pire. La région est caractérisée par des reliefs très accidentés, une structure lithologique généralement tendre, des précipitations le plus souvent orageuses au moment où les terres cultivables subissent une forte pression anthropique. Ceci s'exprime notamment par la dégradation des sols et leur fertilité qui se traduit généralement par des bouleversements socioéconomiques et écologiques le plus souvent irréversibles. Au cours de cette recherche, on a étudié de près les cicatrices et les remèdes propices à l'érosion hydrique au Maghreb à travers l'unité géographique du bassin versant de l'oued Barbara (Tunisie septentrionale). Dans un premier temps, le travail consiste à montrer la gravité de la situation par la réalisation de la carte de l'érosion hydrique à travers la méthode de la direction des forêts de la Tunisie (DF/FAO-SIDA) et l'équation universelle des pertes en sols (USLE). La première méthode, qui a diagnostiqué le fléau de l'érosion hydrique sur son aspect qualitatif, a mis en évidence que le ravinement est le processus érosif le plus actif et le plus sévère dans la zone à l'étude. Quant à l'USLE, elle a permis de quantifier le phénomène érosif à une moyenne annuelle des pertes en sol de l'ordre de 36,13 tonnes/ha. Par la suite, des enquêtes et des entrevues auprès des exploitants agricoles et des intervenants locaux de la zone à l'étude ont été faites dans le but d'identifier des aménagements de CES propices à la région pour la lutte antiérosive. Enfin, la projection de ces aménagements déjà définis sur la carte d'érosion hydrique a conduit à l'obtention d'un scénario antiérosif intégré dont l'utilisation pourra sensiblement améliorer, voir même réduire en grande partie les conséquences désastreuses du phénomène de la dynamique de l'érosion hydrique au niveau du bassin versant de l'oued Barbara. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Érosion hydrique, gestion intégrée, conservation des eaux et des sols, Maghreb, Tunisie, Kroumirie.

The nitrogen has provided a significant increase in production saline environment and reduces the effect of the salts . This work aimed to study the effects of different levels of salinity of irrigation water and nitrogen applied through fertigation in evapotranspiration and yield of pumpkin, the climatic conditions of the region of Mossoró - RN. An experiment in field conditions at the Experimental Farm UFERSA, Mossoró, RN was developed. The treatments consisted of irrigation application with five salinity levels (S1 = 0.5, S2 = 1.5, S3 = 2.5, S4 = S5 = 3.5 and 4.5 dS m- 1) and three Nitrogen doses ( 30 , 100 , 170 % of the recommended dose) . To estimate the ETo Penman - Monteith equation parameterized by FAO was used. The meteorological data required for estimating ETo were collected by an automatic weather station, installed in the experimental area. The ETc was measured by four weighing lysimeters installed in salinity levels S1 and S5. The nutritional status of plants was evaluated by foliar analysis of the flowering period. Periodic reviews of the evolution of soil salinity were performed using soil samples throughout the crop cycle. The results showed that ECT decreased between the irrigation water S1 and S5, where during the entire evaporation cycle was 300.29 and 279.20 mm, respectively. As for the mean values Kc's the phenological stages I, II, III, IV, 0.42 , 0.68 , 1.08, 0.78 for the S1 treatment and 0.41 , 0.62 , 0.92, 0.60 for the S5 treatment , showing that the obtained for Kc's were always higher than those obtained for Kc's S5 level S1 level . There was a significant effect of nitrogen on the yield components, except for the average mass of total and marketable fruit. The total and marketable yield of fruits were significantly affected by the quality of the irrigation water and by nitrogen rates / A maior demanda por água para irrigação tem levado os agricultores a utilizarem águas com salinidade mais elevada, sendo que sua utilização fica condicionada à tolerância das culturas à salinidade e ao manejo da irrigação. A adubação nitrogenada tem proporcionado um aumento significativo na produção e em ambiente salino reduz o efeito dos sais. Este trabalho teve como objetivo estudar os efeitos de diferentes níveis de salinidade da água de irrigação e de doses de nitrogênio aplicado via fertirrigação na evapotranspiração e na produção da abóbora, nas condições climáticas da região de Mossoró-RN. Foi desenvolvido um experimento em condições de campo, na Fazenda Experimental da UFERSA, Mossoró, RN. Os tratamentos foram compostos da aplicação de irrigação com cinco níveis de salinidade (S1=0,5; S2=1,5; S3=2,5; S4=3,5 e S5=4,5 dS m-1) e três doses de Nitrogênio (30, 100, 170 % da dose recomendada). Para estimativa da ETo foi utilizada a equação de Penman-Monteith parametrizada pela FAO. Os dados meteorológicos necessários para a estimativa da ETo foram coletados por uma estação meteorológica automática, instalada na área experimental. A ETc foi medida por quatro lisímetros de pesagem, instalados nos níveis de salinidade S1 e S5. O estado nutricional das plantas foi avaliado pela análise foliar no período de floração. Foram realizadas avaliações periódicas da evolução da salinidade do solo, usando amostras de solo ao longo do ciclo da cultura. Os resultados mostraram que a ETc diminuiu entre a água de irrigação S1 e S5, onde a evapotranspiração total durante o ciclo foi de 300,29 e 279,20 mm, respectivamente. Quanto aos Kc s verificaram-se os valores médios nos estádios fenológicos I, II, III e IV de 0,42, 0,68, 1,08, 0,78 para o tratamento S1 e 0,41, 0,62, 0,92, 0,60 para o tratamento S5, mostrando que os Kc s obtidos para o nível S1 foram sempre maiores que os Kc s obtidos para o nível S5. Houve efeito significativo do nitrogênio sobre os componentes de produção, exceto para a massa media dos frutos totais e comerciais. A produtividade total e a comercial de frutos foram significativamente afetados pela qualidade da água de irrigação e pelas doses de nitrogênio

A literatura de autoajuda é um fenômeno recente sobre o qual poucas considerações foram tecidas. Dentre seus muitos representantes, encontram-se aqueles que se utilizam amplamente de recursos científicos para demonstrar seu ponto e embasar suas orientações. Esta dissertação se debruça sobre a obra de dois autores de best sellers deste tipo, Allan e Barbara Pease, e possui o intuito de discuti-la enquanto material de divulgação científica. A partir da análise etnográfica, tentei contextualizar esta produção de autoajuda científica, buscando conecta-la com aspectos mais amplos da sociedade englobante, e investigar as noções de gênero, sexo e natureza contida neles. Esse esforço é realizado sob o viés da investigação sobre a divulgação científica, a saber, a relação entre expertise científica e público leigo Assim, mobilizo referências que exploram a relação entre o conhecimento científico e o público leigo, de modo a não toma-la como relação de mão única. Através da análise do conteúdo dos livros dos autores são pensadas as categorias de autoajuda científica e o modo como são representadas as noções de sexo e gênero. Do mesmo modo, a investigação de algumas fontes científicas mobilizadas por Allan e Barbara Pease permitem pensar o que está em jogo neste tipo de produção literária.

La présente thèse aborde les enjeux liés à la traduction de poèmes rédigés dans un style classique, tels que ceux rédigés au XIXe siècle par exemple. Le cadre de cette étude porte sur les langues française et anglaise, et l’argumentaire se fonde sur le Raven d’Edgar Allan Poe et cinq de ses traductions, produites par Charles Baudelaire, Stéphane Mallarmé, Maurice Rollinat, Paul Laurendeau et moi-même. D’abord, j’aborde les liens existant entre ces cinq traductions et quatre théories prescriptives de la traduction qui décrivent précisément les principes qui régissent les manières de traduire auxquelles nous (les cinq traducteurs de l’œuvre à l’étude) avons eu recours. Je souligne l’importance d’une traduction le plus près possible du discours (tel que le conçoit Henri Meschonnic) et des effets phonétiques présents dans l’œuvre source. Ensuite, je retrace l’histoire du Raven et analyse 12 segments témoin qui serviront de points de repère pour l’analyse. Enfin, j’analyse les cinq traductions en confrontant les 12 segments témoin aux passages qui leur correspondent dans chacune des traductions. En traduction poétique, il importe de s’attacher au discours, au rythme, aux figures de style, à la sémantique et aux réseaux phonétiques contenus dans l’œuvre source, tout en modifiant sa structure de strophe le moins possible. Ce faisant, la tension interne du poème est conservée, car la très grande majorité des composantes de l’œuvre originale est rendue dans le poème cible. Poème cible constitue un aspect important de la présente thèse, puisqu’il est primordial de créer, dans la langue d’arrivée, un poème qui réponde aux mêmes critères, aux mêmes exigences de qualité que la poésie classique. Cette conception de la tâche d’un traducteur-poète se trouve cristallisée dans la traduction que j’ai faite du Raven. Enfin, dans l’annexe se trouvent le Raven de Poe et les cinq traductions que j’ai mentionnées au premier paragraphe du présent résumé.
