This thesis aims to investigate how local newspapers in Sweden frame newsstories involving asylumseekers and how the asylseekers in those stories are constructed from a postcolonial theoryperspective. Furthermore this thesis aims to analys and show the connection between the written word in the articles and a larger, social dimension where ideologies compete for cultural hegemony. To match the aims of this thesis we used a critical discourse analysis, more specificly one influenced by van Dijks socio-cognitive CDA and applied it to five articles from three different newspapers.Our analysis showed that the articles constructed the asylumseekers as Others, and created a dinstinct line between the asylumseekers and the other participants in the texts. This line, based on a constructed community including the article, the reader and some of the participants but excluding the asylumseekers, got significant meaning in the articles when the asylumseekers got identified as a homogenic social group. A perspecive coming from the constructed community and not from themselfes and therefor denying the asylsumseekers their right to define themselves.

Thesis (MTh (Old and New Testament))--University of Stellenbosch, 2006. / This paper undertakes a detailed study of Matt 6:19-34 for the specific purpose of accounting for the unique context and content of the material/financial ethic being articulated here by Jesus. The passage, made up of four pericopes, is located within the first of the five discourses of Jesus recorded in Matthew’s Gospel in which Jesus evidently articulates the ethical standards required of the children of the emerging Kingdom of God. The need for such a study stems from an understanding that the passage, indeed the Sermon as a whole, has been treated by traditional scholarship in a somewhat distanced and abstract manner i.e. it has been read without adequate cognisance being taken of the particular socio-linguistic and socio-historical context in which it was originally formulated and articulated. Relatively recent social-scientific and socio-historical New Testament scholarship, however, has provided a specific set of interpretive tools that enable a modern reader to make a far more dynamic and context-sensitive interpretation possible. Accordingly, this paper undertakes a socio-rhetorical analysis of Matt 6:19-34, together with a social-scientific and socio-historic/financial/religious analysis of the eastern Mediterranean world of late Second Temple times. Together these interpretive tools shed new light on the text and provide the opportunity for re-reading that text in a way that, hopefully, more closely articulates the ethic as an original audience might have heard it. Specifically, the use of these interpretive tools provide insights into why it was that Jesus explicitly prohibited worry, some six times in the passage, amongst the children of the Kingdom concerning the provision of their food, drink and clothing i.e. the tools provide something of an explanation for both the rhetorical force of the ethic and the underlying realities that gave rise to its formulation in the first place. These insights are then applied in an attempt at formulating a dynamically equivalent ethic that might be appropriated and applied by present day children of the Kingdom reading the passage today.

My aim with this essay is to analyse how the theme of sexuality and love in two dystopian novels – We  (1924),  by Yevgeny Zamyatin and Kallocain  (1940), by Karin Boye – relate to “the modern project”, a term I use to identify a cluster of important ideas that profoundly impacted society in the first decades of the 20th century. My analysis is based on a theoretical point of view claiming that dystopian novels present a critical perspective on society, and that they deal with issues, problems and values specific to the period in which they were written. Using a comparative method, where “the modern project” works asan “Ansatzpunkt”, I explore a variety of texts studying the theme of love and sexualityin We  and Kallocain  from different perspectives. I further discuss how both novels criticize societies where some of the ideas from “the modern project” are realized in unexpected ways: the “bourgeois family” is gone and the state performs some of its duties, sexuality is reduced to biological needs and reproduction, and love relationships are seen as egotistical and irrational. Even though these societies are trying hard, they can’t stop their citizens from using love and sexuality as a means to connect to one another and build a resistance. My conclusion is that both Zamyatin and Boye most likely were inspired by the writings of Sigmund Freud, who at that time was highly influential. In this light their novels can beinterpreted as presenting the human libido (We) and insights gained through psychoanalysis (Kallocain) as defences against collectivistic totalitarian states.

Characterising the geochemistry and speciation of major contaminant radionuclides is crucial in order to understand their behaviour and migration in complex environmental systems. Organic complexing agents used in nuclear decontamination have been found to enhance migration of radionuclides at contaminated sites; however, the mechanisms of the interactions in complex environments are poorly understood. In this work, radionuclide speciation and sorption behaviour were investigated in order to identify interactions between four key radionuclides with different oxidation states (Cs(I) and Sr(II) as important fission products; Th(IV) and U(VI) as representative actinides), three anthropogenic organic complexing agents with different denticities (EDTA, NTA and picolinic acid as common co-contaminants), and natural sand (as simple environmental solid phase). A UV spectrophotometric and an IC method were developed to monitor the behaviour of EDTA, NTA and picolinic acid in the later experiments. The optimised methods were simple, applied widely-available instrumentation and achieved the necessary analytical figures of merit to allow a compound specific determination over variable background levels of DOC and in the presence of natural cations, anions and radionuclides. The effect of the ligands on the solubility of the radionuclides was studied using a natural sand matrix and pure silica for comparison of anions, cations and organic carbon. In the silica system, the presence of EDTA, NTA and, to a lesser extent, picolinic acid, showed a clear net effect of increasing Th and U solubility. Conversely, in the sand system, the sorption of Th and U was kinetically controlled and radionuclide complexation by the ligands enhanced the rate of sorption, by a mechanism identified as metal exchange with matrix metals. Experiments in which excess EDTA, NTA and picolinic acid (40 – 100 fold excess) were pre-equilibrated with Th and U prior to contact with the sand, to allow a greater degree of radionuclide complex formation, resulted in enhanced rates of sorption. This confirmed that the radionuclide complexes interacted with the sand surface more readily than uncomplexed Th or U. Overall this shows that Th and U mobility would be lowered in this natural sand by the presence of organic co-contaminants. In contrast, the complexation of Sr with the complexing agents was rapid and the effect of the ligands was observed as a net increase on Sr solubility (EDTA, picolinic acid) or sorption (NTA). As expected, Cs did not interact with the ligands, and showed rapid sorption kinetics. Finally, ESI-MS was used to study competitive interactions in the aqueous Th-Mn-ligand ternary system. Quantification presented a challenge, however, the careful approach taken to determine the signal correction allowed the competitive interactions between Mn and Th for EDTA to be studied semi-quantitatively. In an EDTA limited system, Th displaced Mn from the EDTA complex, even in the presence of a higher Mn concentration, which was consistent with the higher stability constant of the Th-EDTA complex.

Denna uppsats undersöker vilket innehåll USA:s president Donald Trump fyllde begreppen ”vi” och ”dom” med via sitt Twitterkonto under de sista tre veckorna av presidentvalrörelsen 2016. Analysen motiveras av att den kan ge en fingervisning om vilken politik Trump kommer att verka för som president. Forskningsfrågan för studien är: Med vilket innehåll fyller Donald Trump, genom sitt Twitterkonto, signifikanterna ”vi” och ”dom”? Uppsatsen ingår i forskningsfältet politisk kommunikation och utgår från ett teoretiskt ramverk som lägger stor vikt vid språkets funktion i konstruktionen av verkligheten. Som metod används diskursanalys, där betydelserna för ”vi” och ”dom” tolkas utifrån hur begreppen sammankopplas med andra betydelsebärande begrepp och den kontext som tweetarna är skrivna i. I uppsatsens analys framkommer det att Trump konstruerar en motsättning mellan ”vi” och ”dom” som baseras på religiös tillhörighet och ursprung, och där ”dom” som är muslimer eller har invandrat från Latinamerika utgör problemet. Utifrån den konstruerade problembilden kan politiska krav som att stoppa invandringen från muslimska länder och att deportera miljontals invandrade från Latinamerika, framstå som logiska lösningar. Lösningar som också har presenterats av Donald Trump. Denna typ av politiska förslag riskerar leda till att ytterligare öka främlingsfientligheten och de sociala spänningarna i USA. / This paper examines the content US President Donald Trump filled the terms "us" and "them" via his Twitter account during the last three weeks of the presidential election campaign in 2016. The analysis is motivated because it can give an indication of what kind of policy Trump will suggest as president. The research question for this study is: With what content does Donald Trump, through his Twitter account, fill the signifiers "us" and "them"? The essay is part of the research field of political communication and is based on a theoretical framework which places emphasis on the function language has as a tool for the construction of reality. Discourse analysis is used as method, which implicates that the meanings of "us" and "them" is interpreted on the basis of how the concepts are connected with other meaningful concepts and the context in which the tweets are produced. According to the analysis of this paper, Donald Trump constructs an opposition between "us" and "them" based on religious affiliation and origin, in which "them" – who are Muslim or immigrants from Latin America – are the problem. Based on this constructed conflict, the political demands to stop immigration from Muslim countries and deport millions of immigrants from Latin America, appears as logical solutions. Solutions that has also been presented by Donald Trump. This type of policy proposals could lead to a further strengthening of the social divisiveness and an increase of xenophobia in USA.

Approved for public release, distribution is unlimited / For over half a century the NPS Aerolabʼ Low Speed Wind Tunnel located in Halligan Hall of the Naval Postgraduate school has served to provide students and faculty with meaningful aerodynamic data for research and problem analysis. New data acquisition hardware was installed three years ago but never fully verified, and contained no integrated software program to collect data from the strain-gauge balance pedestal. Existing National Instruments based hardware for the NPS low-speed wind tunnel was reconfigured to obtain data from the strain-gauge pedestal. Additionally, a data acquisition software program was written in LabVIEW⠭ to accommodate the hardware. The Virtual Instruments (VI) program collects and plots accurate data from all four strain gauges in real-time, producing non-dimensional force and moment coefficients. A research study on the performance of an OH-6A helicopter fuselage was conducted. NPS Aerolabʼ wind tunnel tests consisted of drag, lift, and pitching moment measurements of the OH-6A along yaw and angle-of-attack sweeps. The results of the NPS wind tunnel data were compared against testing conducted on a full-scale OH-6A helicopter in NASA Ames' 40 ft. x 80ft. wind tunnel, along with the U.S. Army's Light Observation Helicopter (LOH) wind tunnel tests. Results of current testing substantiate the LabVIEW⠭ code. / Ensign, United States Navy

Im Zentrum dieser Arbeit standen ramanspektroskopische Untersuchungen der elektronischen spin-flip-Übergänge an semimagnetischen (Zn,Mn)Se Proben. Hierbei wurden sowohl Quantentrogstrukturen untersucht als auch volumenartige Proben. Ziel der Forschung war dabei, ein tieferes Verständnis der Wechselwirkungen der magnetischen Ionen mit den Leitungsbandelektronen der Materialien zu gewinnen. Im Hinblick auf mögliche zukünftige spin-basierte Bauelemente lag das Hauptaugenmerk auf dem Einfluss von n-Dotierung bis zu sehr hohen Konzentration. Hierfür standen verschiedene Probenreihen mit unterschiedlichen Dotierungskonzentrationen zur Verfügung. / In the present doctoral thesis, spin flip Raman studies of semimagnetic (Zn,Mn)Se samples were in the focus of interest. Quantum wells as well as bulk-like materials were investigated. The main goal was a better understanding of the exchange interaction behaviour of heavily n-doped semimagnetic samples. The influence of doping on the exchange interaction is of special relevance with regard to spintronics applications. Several series of high quality MBE-grown (Zn,Mn)Se -samples samples were available.

ZnO-based semiconductors were studied by Raman spectroscopy and complementary methods (e.g. XRD, EPS) with focus on semimagnetic alloying with transition metal ions, doping (especially p-type doping with nitrogen as acceptor), and nanostructures (especially wet-chemically synthesized nanoparticles). / ZnO-basierte Halbleiter wurden mittels Ramanspektroskopie und komplementärer Methoden (z.B. XRD, EPS) untersucht mit den Schwerpunkten semimagnetische Legierung mit Übergangsmetallen, Dotierung (vor allem p-Dotierung mit Stickstoff als Akzeptor) und Nanostrukturen (vor allem nass-chemisch hergestellte Nanopartikel).

Neste sentido, as cascas residuais oriundas do processo de beneficiamento de arroz vêm sendo utilizadas como combustível, visando ao aproveitamento energético. Mediante a queima da casca de arroz é gerada a cinza de casca de arroz composta basicamente de sílica, potencializando o uso deste resíduo em diferentes segmentos industriais. Muitos trabalhos aplicam a cinza de casca de arroz na construção civil, visto que grande parte dessas cinzas apresenta características pozolânicas decorrente da alta concentração de sílica amorfa presente no material. Pesquisas têm demonstrado que estas cinzas também apresentam potencialidade de aplicação como material adsorvente. No entanto, a cinza de casca de arroz apresenta-se, muitas vezes, como um material heterogêneo tanto na sua composição granulométrica quanto na sua composição química. Estas características podem interferir nas aplicações limitando seu aproveitamento. A segregação dos resíduos é uma técnica amplamente aplicada no gerenciamento de resíduos sólidos industriais e pode oportunizar a reciclagem dos materiais segregados. Neste contexto, este trabalho tem como proposta principal contribuir para a valorização do resíduo cinza de casca de arroz como co-produto através da etapa de segregação. Foi estudada a influência da segregação da cinza da casca de arroz nas características fisicoquímicas, bem como no seu desempenho como material pozolânico e adsorvente. As amostras e as frações segregadas foram caracterizadas através de parâmetros físicos (perda ao fogo, massa específica, área superficial, distribuição granulométrica) parâmetros químicos (análise química, difração de raio-X) e parâmetros microestruturais (microscopia eletrônica de varredura com espectro de dispersão de energia-EDS). A atividade pozolânica foi determinada após moagem das amostras e das frações através de ensaios de Pozolanicidade com o cimento e Condutividade Elétrica. Os ensaios de adsorção foram realizados com soluções de Cr(VI). O cromo residual foi quantificado pelo método colorimétrico da 1,5- difenilcarbazida. Resultados obtidos demonstraram que a segregação configura-se numa etapa importante, pois remove impurezas e contaminantes presentes na amostra, bem como origina frações diferentes, evidenciadas nos ensaios de caracterização. Nos ensaios de atividade pozolânica, observou-se que a influência da segregação relaciona-se com o tipo de processo de combustão aplicado para a obtenção da cinza. Nos ensaios de adsorção, observou-se que a segregação influenciou na remoção de cromo hexavalente. O estudo demonstrou, nas condições testadas, a viabilidade do uso de cinza de casca de arroz na adsorção do metal quando ajustados os parâmetros do processo que favoreçam a remoção dos íons de cromo. / The main objective for the industry is to reduce the generation of wastes, or to find better uses to them, such as in the own productive process or as raw material in the elaboration of other materials. Also, a great amount of funds has been invested in researches for the transformation of such wastes, in by-products of commercial interest. In this way, the rice husk from the rice processing have been used as combustible, for producing energy. Rice husk ashes are generated from the rice husk burning, which presents a potential to be used as raw material in the production of several products in different industry sectors. Most of the works apply the rice husk ash in civil construction, because a great part of those ashes present pozzolanic characteristics as a result of their amorphous chemical structure and the high silica content. In fact, between other factors, the pozzolanicity of rice husk ash depends on the thermal process applied to the rice husk during burning. Researches have been demonstrating that the ashes also may be potentiality applied as adsorbent. However, the rice husk ash comes, many times, as a heterogeneous material so much in your particle size distribution as in your chemical composition. These characteristics can interfere in the applications limiting your use. The segregation of the wastes is thoroughly a technique applied in the administration of industrial solid waste and it can guarantee the recycle of the segregated materials. This work has as main objective to contribute for the valorization of the waste rice husk ash as coproduct through the segregation stage. It was studied the influence of the segregation of the rice husk ash, in physical-chemical characteristics, as well as your acting as pozzolanic and adsorbent. The samples and segregated fractions were characterized via physical (fire loss, specific gravity, specific surface area, particle size distribution), chemical (chemical analysis, X Ray diffraction) and microstructural parameters (scanning electronic microscopy with energy dispersion spectroscopy – EDS). The pozzolanic activity was determined after grinding the samples and the fractions via Cement pozzolanic and Electric Conductivity Methods. The adsorption rehearsals were accomplished with Cr(VI) solutions, that was quantified by the colorimeter method using 1,5-difenilcarbazida. Results demonstrated that the segregation became an important step, because removes impurities and contaminants from the samples and also originates fractions with different characteristics. It was observed, in pozzolanic activity, that the influence of the segregation links with the type of applied combustion process for the obtaining of the ash. It was observed, in adsorption rehearsals, that the segregation influenced in the removal of chromium (VI). Adsorption results showed, considering the experimental conditions in this work, the viability of the use of rice husk ash in the adsorption of chromium (VI) when adjusted the process’s parameters that guarantee the removal of chromium.
