chemical energy storage

description: Chemical energy storage in the context of so-called Power-to-X (PtX) processes will play a key-role in the future energy system due to the increasing power production from renewable energy and the urging defossilization of industry and transport sector. Among possible PtX products, methanol produced from carbon dioxide (CO2) and sustainably produced hydrogen (H2) is going to play a key-role due to its high relevance in the global fuel and chemical market. Compared to conventional methanol synthesis based on fossil feedstocks, methanol synthesis based on CO2-rich gas streams captured from industrial processes, biomass processing or ultimately captured from air is subjected to decreased equilibrium conversions, inhibited reaction kinetics and an accelerated catalyst aging. Moreover, the production of H2 from water electrolysis operated with renewable power and the coupled CO2-supplying industrial process can impose dynamic fluctuations to syngas supply unknown to the current-state-of-the-art. For these new boundary conditions, design of the synthesis reactor and operation of the process become more challenging and do demand for detailed models for each unit operation in the synthesis process. However, for the kinetic simulation of the synthesis reactor under these conditions only scarce knowledge exists in the scientific community. Thus, a detailed kinetic description of the reaction network in industrial reactors is required to enable methanol synthesis from sustainable resources in the future. To tackle that deficit, this work used a scale-flexible simulation platform to design a miniplant facility with the reactor reproducing the thermochemical behavior of an industrial steam cooled tube bundle reactor with a high agreement. An innovative analytical concept using the highly resolved fiber optic temperature measurement to analyze the axial temperature profile in the reactor combined with an FTIR product composition measurement was implemented to derive a kinetic model for reactor- and process design validated over the complete range of relevant load conditions for Power-to-Methanol (PtM) processes. Comparison to kinetic models obtained from literature highlighted both the scientific value of methodical approach implemented in this work and the high relevance of the herein proposed kinetic model for the practical implementation of PtM processes. Furthermore, the validation of the dynamic reactor model implemented in this work by a exemplary load change performed with the miniplant showed a high level of agreement between the experimental data and the simulation results. Thus, the scientific potential of the herein proposed miniplant validation approach for the investigation of stationary and dynamically operated PtX processes could be demonstrated.

description: A study was conducted in the larger Melbourne area to ascertain, as part of the entrepreneurial process, the relationship between human capital of ethnic entrepreneurs and their networking attributes. Contrary to research elsewhere, there was only limited association between human capital and personal networking of ethnic entrepreneurs among the respondents in this research. There was also only limited association between the ethnic entrepreneurs' involvement with the co-ethnic community and their personal networking with the entrepreneurs' utilization of a co-ethnic network. Finally, there was only limited association between ethnic entrepreneurs' human capital and their joining non co-ethnic business networks.

description: A-type lamin mutations are associated with degenerative disorders causing dilated cardiomyopathy, Charcot-Marie-Tooth neuropathy and Limb-Girdle Muscular Dystrophy. Our lab has identified MLIP; a novel protein that interacts with lamin A/C. Knocked down MLIP expression in C2C12 myoblasts down regulates myogenic regulatory factors, MyoD and Myogenin, which delays myogenic differentiation. We hypothesize that MLIP is essential for myogenic differentiation. Our goal is to define the MLIP associated pathways involved in myogenic programming. Gene expression profiling of MLIP stably knocked down C2C12 cells, identified 30 genes implicated in human disease. Mutations in five of those genes (DMPK, HSPB8, LMNB2, NEFL and SGCD) cause muscular dystrophy, neuropathies, and lipodystrophies that have phenotypic overlap with laminopathies. Further studies involving the MLIP knocked down cell lines demonstrated that in the absence of puromycin, MLIP protein expression returns to normal. This in turn affects the interpretation of the gene expression data and attempted MLIP recovery experiments.

description: Mit einem Post-Industry Polypropylen Rezyklat wurden Schaumperlen mit Schüttdichten bis 18 ± 1 g/l hergestellt. Als Treibmittel wurde überkritisches Kohlenstoffdioxid verwendet. Die Schaumperlen konnten nicht im Dampf-, jedoch im Radiofrequenz-Prozess zu Formteilen versintert werden. Das Rezyklat wurde zuvor mit Talk und 2-6-Naphtalendicarboxiamid, einem -Nukleierungsmittel, compoundiert. Der Schmelzpunkt der Kristalle, welche in der -Modifikation vorlagen, ist 12 ± 2 °C niedriger als der Schmelzpunkt der Kristalle, welche in der -Modifikation vorlagen. Die Dichte der Schaumstoffe wurde durch Talk und -Nukleierungsmittel signifikant verringert. Das -Nukleierungsmittel fungiert als Kristallisationskeim und als Nukleierungsmittel für die Entstehung von Gasblasen in der Polymermatrix. Das Erscheinungsbild der Schaumperlen in den Versuchen ist heterogen. Stieg die Dichte der Schaumperlen, stieg deren Homogenität. Wurde der Volumenstrom der Wasser-Polymer-Dispersion erhöht, nachdem der Autoklav geöffnet worden ist, stieg die Homogenität der Schaumperlen ebenfalls. Die Verarbeitung der Schaumperlen im Radiofrequenz-Prozess war wegen Füllstoffen im Polymer möglich.
description: Foam particles with bulk densities up to 18 ± 1 g/l were manufactured with recycled polypropylene used in industry. Supercritical carbon dioxide has been used as a blowing agent. The foam particles could not be sintered in a steam-based process, but in a radiofrequency-based process. The recycled polymer has been compounded with talc and 2,6-Naphthalenedicarboxamide, a -nucleating agent. The melting point of crystals ordered in the -modification was 12 ± 2 °C lower than of those ordered in the -modification. The density of the foams has been significantly lowered due to talc and the -nucleating agent. The -nucleating agent is working as a nucleating agent for the formation of crystals and gas bubbles in the polymer matrix,.The appearance of the foam particles is heterogeneous, likely due to an early expansion of granules in the autoclave. With increasing density, the homogeneity of the foam particles increased. By increasing the volume flow rate of the water-polymer-dispersion, after the autoclave was opened, the homogeneity of the foam particles was increased, too. The processing of foam particles was possible due to fillers in the polymer.

description: Recently, as a reaction to the energy crisis fueled by Russia's aggression against Ukraine, the EU launched the REPowerEU plan in 2022 to use more renewable energy, reduce energy consumption and diversify the energy supply (European Commission 2024a). One key focus area for decarbonization and energy saving is the private heating sector. Heat pumps take a central role in the heating system's flexibilization and decarbonization. In essence, the aim of this study is to assess heat pump´s flexibility potential, specifically concentrating on the intraday market by comparing it against other pricing mechanisms and examining different setups across various household heat profiles. To determine optimal load shifting schedule on intraday market, the study employs Mixed Integer Linear Program (MILP) optimization model. Model generates potential yields on intraday market, as well as for dynamic day-ahead and flat heat pump tariff, for data available for years 2022 and 2023. By comparing revenue streams, this study points to the flat heat pump tariff as most attractive pricing mechanism in terms of cost reduction. After further consideration, where financial incentives granted to flat heat pump tariff were isolated, the study settles on intraday market as best solution for private households offering flexibility with heat pumps. Positive outcome for intraday market can be attributed to the market´s high volatility, especially effective among households with high energy demand. To conclude, the research fills a gap in previous studies by providing insights into heat pumps offering their capacities on intraday market in comparison to other pricing mechanisms and proves intraday market´s high suitability due to its the high volatility.

Взаимодействие различных видов искусства в произведениях поэтов серебряного века является основополагающей характеристикой их творческого метода. М. Кузмин как яркий представитель художников слова начала ХХ века был наделен талантами композитора, исполнителя, писателя, поэта, критика. Среди близких друзей поэта были художники – Сомов, Сапунов, Судейкин. Пристрастия Кузмина к различным видам искусства нашли свое отражение в его работах. Например, «Лесок» – сложное музыкально-драматическое произведение, созданное в 1922 году, имеет авторское жанровое определение «лирическая поэма для музыки с объяснительной прозой в трех частях» и содержит отсылки не только к произведениям Шекспира, Гофмана, Апулея, но и указание и даже описание некоторых картин, например, Ботичелли, Бердсли и др.

description: This thesis examines perceptions of lower-class female prostitutes and prostitution in eighteenth-century London. It reveals that throughout the Hanoverian period perceptions of prostitution were shaped by sensibilities about morality, the social order, and sin. To explore attitudes towards prostitution in eighteenth-century London, this dissertation evaluates how governing elites, ecclesiastical authorities, contributors to the newspaper press, and popular commentators discussed prostitution. This dissertation engages with two main assumptions about prostitution in eighteenth-century London. First, it demonstrates that there is more continuity in perceptions of prostitution than historians have recognized; attitudes towards prostitutes did not shift from hostility to sympathy in a straight-forward manner. Second, this dissertation reveals that prostitution was regarded by Augustan and Hanoverian Londoners as a significant social problem because it embodied and encapsulated the seven deadly sins – lust, avarice, pride, envy, gluttony, sloth, and wrath. This thesis suggests that prostitutes’ excessive lust and avarice were not seen as disparate issues, but were often discussed together. Paradoxically, discussants recognized that financial considerations drove some women into prostitution, but these women were regarded as abnormally greedy and corrupt because they resorted to deceptive tactics. Pride and envy were associated with prostitution because Hanoverians believed some prostitutes bought extravagant clothes and cosmetics to conceal their lowly status and enhance their appearance to emulate elites. Hanoverians regarded these prostitutes with trepidation because they threatened to undermine their hierarchically ordered society. Prostitutes’ proclivities towards drunkenness and idleness were associated with gluttony and sloth. Commentators feared that drunken and idle prostitutes would encourage men to engage in these dissolute activities, leading to greater disorder. Wrath was closely associated with prostitution because of its association with violence. Although prostitutes were both the victims and perpetrators of assault, incidents in which prostitutes were assailants were reported more frequently, suggesting that Britons regarded prostitutes as disorderly, sinful criminals. Each chapter also brings attention to concerns regarding prostitutes’ lack of self-control and their apparent ability to cause men to lose self-control; how double standards of morality influenced discussions of prostitution; the consequences of prostitutes’ criminality and ability to deceive Londoners; and the various institutions, organizations, and suggestions proposed and established to reform prostitutes and eradicate sin from society.

description: A new generation of power electronic systems with reduced losses, size and costs is emerging due to the rapid development of gallium nitride (GaN) transistors. These transistors are fabricated in the GaN-on-Si technology and have a lateral structure, which enables the monolithic integration with peripheral functions such as gate driver, sensing, protection, and even control. This research work extends the monolithic integration in the GaN technology by introducing and investigating devices, buildings, and function blocks towards a new category of highly functional GaN power ICs for low-cost high-efficient switching regulator applications. Integration levels are introduced for the classification of GaN power ICs. A GaN power IC platform with devices as well as building blocks is investigated regarding its characteristics and its related design issues are analyzed. Thereby, the devices are divided into active and passive and the function blocks into digital and analog. Based on this GaN power IC platform, two case studies are presented for a DC-DC synchronous buck converter and AC-DC active rectifier diode, which contributes to efficient, cost-effective and more sustainable power electronic products using functional integration in GaN.

description: Metamaterialien und programmierbare Materialien haben Eigenschaften, die in der Natur nicht vorkommen. Eine dieser Eigenschaften ist die Bistabilität. Bistabile Strukturen besitzen zwei stabile Verformungszustände, welche durch einen instabilen Zustand getrennt sind, und die stabilen Zustände ohne Hinzufügen von Energie halten kann. Durch die Zufuhr von mechanischer Energie kann zwischen denn stabilen Zuständen gewechselt werden. Zurzeit werden Metamaterialien hauptsächlich durch additive Fertigungsverfahren hergestellt. Das Ziel dieser Arbeit ist, eine bistabile Zelle durch Thermoformen herzustellen und diese auf ihre Funktion und Anwendungsmöglichkeiten zu überprüfen. Um dies zu erreichen, werden bistabile Strukturen in Teil-Geometrien zerlegt, die durch Thermoformen fertigbar sind. Hierbei wird eine Polystyrol-Folie mit Hilfe einer 3D gedruckten Form umgeformt. Die Teil-Geometrien werden anschließend durch Lösemittelschweißen zu einer Gesamtstruktur verbunden. Mit Hilfe von Zugversuchen werden die Proben getestet und charakterisiert. Die Versuche ergaben, dass bistabile Zellen durch Thermoformen hergestellt werden können.
description: Metamaterials and programmable materials are materials with properties that do not occur in nature. One of these properties is bistability. Bistable structures have two stable states which are separated by an unstable state, and can hold the stable states without adding a force. By supplying mechanical energy, it is possible to switch between the following stable states. Currently, metamaterials are mainly produced by additive manufacturing processes. The goal of this study is to fabricate a bistable cell by thermoforming and to test it for its function and possibilities. To achieve this, bistable structures are decomposed into partial geometries that can be manufactured by thermoforming. A polystyrene film is formed over a 3D-printed mold. The partial geometries are then joined and solvent welded to form the overall structure. Tensile tests are used to test and characterize the specimens. the tests resulted that a bistable cell can be produced by thermoforming.

description: A 3.6 ha experimental fire was conducted in a black spruce peatland forest that had undergone thinning the year prior. After 50 m of spread in a natural stand at 35–60 m min−1, the crown fire (43,000 kW m−1 intensity using Byram’s method) encountered the 50% stem removal treatment; spread rates in the treatment were 50–60 m min⁻¹. Fuel consumption in the control (2.75 kg m⁻²) was comparable to the treatment (2.35 kg m−2). Proxy measurements of fire intensity using in-stand heat flux sensors as well as photogrammetric flame heights had detected intensity reductions to 30–40% of the control. Crown fuel load reductions (compensated by higher surface fuel load) appear to be the most significant contributor to the decline in intensity, despite drier surface fuels in the treatment. The burn depth of 5 cm in moss and organic soil did not differ between control and treatment. These observations point to the limited effectiveness (likely reductions in crown fire intensity but not spread rate) of stem removal in boreal black spruce fuel types with high stem density, low crown base height and high surface fuel load. The observed fire behaviour impacts differ from drier conifer forests across North America.

description: The present work deals with the analysis of the chemical composition of the aqueous phase from the conversion of dried sewage sludge by means of the thermo-catalytic reforming (TCR®) process. In addition, a 3-step purification strategy is presented that allows extensive purification of this aqueous phase while recovering secondary raw materials. The aim of the investigations is the pretreatment of the aqueous phase as a prerequisite for the final purification in a wastewater treatment plant and the associated recovery of raw materials as an alternative to the currently practiced disposal in a hazardous waste incineration. The development of the purification strategy is based on the analysis of the chemical composition of the aqueous phase, taking into account the legal framework and the resulting economic consequences. The cleaning strategy, which is focused on electrooxidation by means of boron-doped diamond electrodes, allows a reduction of the organic carbon of more than 80 %. The inorganic carbon can be removed almost completely, and the ammonia contained can be removed by more than 90 %. The mentioned chemical compounds can be recovered in the form of lime or ammonium sulfate. In addition, hydrogen can be recovered during the electrooxidative treatment of the aqueous phase. The here developed cleaning strategy has clear advantages over the disposal of the aqueous phase practiced to date. For example, the cleaning strategy developed allows the aqueous phase to be precleaned at the TCR® plant site, while at the same time recovering valuable materials. During pretreatment, an average of 307 g of lime and 160 g of ammonium sulfate per liter of aqueous phase can be recovered. In addition, approx. 15 % of the electrical energy required for the removal of the organic carbon can be recovered in the form of hydrogen. Open questions include a possible integration of the developed cleaning strategy into the TCR® process as well as a comprehensive consideration of the economic efficiency. As soon as these questions have been clarified, the developed cleaning strategy can be tested and established on an industrial scale.

Celle-ci s'articule ainsi autour de la notion d'éthique de la traduction : en explorant d'abord certains des récents développements en théorie féministe et en traductologie, nous souhaitons découvrir les fondements de différentes éthiques du traduire afin de les mettre à l'épreuve. Puis, en analysant le style de l'auteure cubaine dissidente et transgressive Ena Lucía Portela en traductions française et anglaise, nous découvrons que la traduction fait subir de nombreux changements au discours transgressif de l'auteure, inscrivant celui-ci dans les normes des cultures d'arrivée. Nous en concluons que la pratique de la traduction doit revoir ses objectifs et ses stratégies et prendre en considération les arguments des théories féministes actuelles si elle veut pouvoir prétendre participer à un dialogue éthique et avoir une « visée résistante ». La présente thèse propose ainsi une réflexion féministe transnationale sur l'éthique et sur la pratique de la traduction littéraire à l'heure actuelle.

description: The current research analyzed the flutter response of the Stonecutters Cable-Stayed Bridge in Hong Kong, which has a twin deck configuration, under the effect of wind. The aerodynamic instability response of the bridge steel deck of the main span is mainly the focus of the current project. Initially, a complete finite element bridge model was created in ABAQUS finite element software, representing all the structural elements of the Stonecutters Cable-Stayed Bridge in a lumped mass bridge model. The natural frequencies and the vibration modes were validated against the data available in the literature at first. Secondly, the effect of the mean wind loading for wind speeds between 35 m/s and 211 m/s were determined. The vertical and horizontal displacements and the torsional angle at mid-span are indicated to determine the bridge performance under mean wind load. Moreover the flutter instability was modeled based on Scanlan’s theory and the response of the bridge model at several different locations along the main and the side span and the top of the tower, were determined for wind speeds of 35 m/s and higher, where this critical aerodynamic instability is expected to occur. In addition, the responses of the bridge under natural wind data were also determined by applying a wind speed recorded data to the bridge model. Finally, the critical flutter wind speed and the flutter frequency were determined by Fast Fourier Transform in MATLAB program. The flutter onset wind speed was also determined.
Brand Europe? An analysis of the interactions between brands, media and national cultures
Creators: name: Mahr, Jackson
Publisher: name: Swinburne
Year: 2024

description: This thesis examines the inter-connected relationships between global brands and Brand Europe and the relationship between the European Union and the complicated processes of globalization. By focusing on a case study of the operation of brands in the European Union, the thesis explores the relationship of brands to neoliberalism and how the global balance of global production, marketing and consumerism is shifting. These issues are examined through the creation of 'Brand Europe', which seeks to articulate the EU's historical development, its gradual expansion, formalization and the cultural and political relationship of Europeans to the broader political entity of this union. The thesis argues that Europe's brand is one that has developed over time and not imposed by the process of integration. Facets of the brand such as its strong social welfare focus are common and integral throughout all nations of the EU, forming part of the common cultural beliefs of these nations and now integrated into the socio-political framework of broader European government. More broadly, the thesis examines how globalization affects the European Union's identity and how this works with its own socio-economic and political duality. It argues that the process of market integration through reduction of internal trading barriers, combined with its framework of worker protection and social welfare, creates a scenario that seems to contradict traditional market-driven, neoliberal theory. At the same time, the process has also generated a closed system of free trade that uses economic mechanisms to close out global free trade, commonly referred to as 'Fortress Europe'. The thesis argues that these seemingly contradictory tendencies are to some extent reconciled through the mechanism of branding, which seeks to promote the most advantageous aspects of the system while obfuscating its less desirable attributes.

Here, a new simulation model based on a neural network is proposed which rapidly predicts the maximum temperature difference in a single battery pouch cell after a charging process. The model considers all relevant geometric and thermal parameters. Using this model, a charging process of a battery module can be computed in less than 18 s. This enables the thermal optimization of pouch cell designs and the comparison of different cooling approaches on module level, which is demonstrated on two exemplary test cases. Furthermore, a tab-cooled battery module prototype using thermally conductive plastic materials is developed and analyzed. The simulation model is partly validated with the prototype and its cooling performance is evaluated on.

description: Equivalence relations are criteria for comparing the behavior of systems. They have important applications in the verification and testing of communications protocols. This thesis presents our investigation on equivalence relations in two parts. Part One contains mainly the theoretical results. It first gives a survey on many important equivalence relations. It then proposes new types of reachability for indeterministic distributed systems and a unified definition which reveals the essential and common features of many equivalence relations. This uniform approach points out that the various equivalence relations differ from one another mainly in the domain of the action sequences, the types of reachability and the observable properties of the reached sets of states. Exhibited behavior equivalence relation is redefined and a new polynomial time algorithm for its verification is presented. Three reduction methods among the equivalence relations are discussed and a number of results on property-preserved transformations are given. A proof that EB equivalence is stronger than testing equivalence in non-strongly convergent labeled transition systems is presented. A disproof of the conclusion existing in literature that EB equivalence is stronger than weak equivalence is provided. Part Two reports our implementation of the various verification algorithms in a system call LTS-EVS in the Sun Workstation.

description: Efficiency of software application is one of the important metrics that are used to measure the quality of software applications. Nowadays, more and more professionals are focusing on programming technology because suitable programming may make the products more efficient. The emergence of multiprocessor systems and multi-core CPUs makes concurrent programs much more popular than sequential programs. However, a great number of large complex software applications that have already been released and are currently being used by many clients are programmed in sequential fashion. Compared to developing the program from scratch again, code refactoring with the concept of concurrent programming would be a better choice. It saves effort, time, manpower and money. This thesis studies the problems of introducing concurrency into large and complex software applications and proposes a methodology for transforming sequential programs into concurrent programs. We successfully speeded up a prototype of IBM Security AppScan Source for Analysis by introducing concurrency into the program. The performance of the application was improved, thus demonstrating the usefulness of the proposed methodology.

description: Die Herstellung von Bauteilen über die uniaxiale Pressverdichtung ist ein etabliertes Formgebungsverfahren in den Bereichen Technische Keramik, Sinterstähle sowie der Hartmetalle. Für Bauteilqualität, Prozesseffizienz sowie für die mögliche Bauteilkomplexität ist das Schütt- und Fließverhalten des eingesetzten Pressgranulates im Prozessschritt Matrizenfüllen ein bestimmender Faktor. Für die Entwicklung keramischer Pressgranulate mit optimalen Fülleigenschaften wurde im Rahmen dieser Arbeit ein detailliertes und grundlegendes Verständnis hinsichtlich der Prozessvorgänge beim Matrizenfüllen mit Fokus auf die Phasen Füllvorgang, Absetzvorgang und resultierendes Füllergebnis erarbeitet. Dies wird komplementiert durch die Analyse der Korrelationen zwischen den primären Granulateigenschaften und dem resultierenden Füllverhalten. Grundvoraussetzung war die Entwicklung eines Methodenspektrums, welches einen über den Stand der Technik hinausgehende qualitative sowie quantitative Bewertung des Matrizenfüllverhaltens erlaubt. Für die Produktentwicklung keramischen Pressgranulate und allgemein von Presspulvern steht das in der Arbeit aufgestellte DoE-Modell zukünftig als Tool zur Verfügung.

description: Wind energy is a fundamental component in the shift towards clean and renewable energy sources and is essential for achieving Sustainable Development Goal 7 [1]. Its sustainable and responsible implementation still requires research, in particular its impact on birds, which are most affected by wind power plants. Birds play a big role in different ecosystems as they are very mobile species, and studying their migration behaviors helps track ecosystems and climate change dynamics. This thesis investigates the potential Artificial Intelligence techniques for bird species classification. We compare the performance of Supervised Contrastive Learning against models trained with Self-Supervised Contrastive Learning and fully supervised models. Our experiments tested the impact of different sets of augmentations, training durations and temperatures on the performance of the models in both pre-training and transfer tasks. Our results show that Supervised Contrastive Learning performs significantly better than Self-Supervised Contrastive Learning, in both pre-training and transfer tasks. For transfer tasks a careful balance between temperature and augmentations is crucial for better performance. Although larger models are needed to fully harness the potential of Supervised Contrastive Learning, the results obtained with ResNet-18 models promise better results with larger architectures.

Tchacos Codex

description: Though discovered in 1945, the First Apocalypse of James from Nag Hammadi Codex V, 3 has received very little attention from the scholarly community. This is primarily due to the fragmentary condition of the text. Previous scholarly engagements with the text have led to the conclusion that the purpose of such a revelatory dialogue was to impart instructions for the ascent of the soul to one about to be martyred. The recent discovery of a second copy of the text simply titled “James” as part of the Tchacos Codex has led to not only a greater amount of scholarly interest, but also to different possible interpretations. From NHC V, 3 it was possible to ascertain a pre- and post- martyrdom revelation of Jesus to James, however, the text from Al Minya clearly shows a third revelatory section wherein the martyrdom of James is used as a means of revelation to Addai, the legendary founder of Eastern Syrian Christianity. Chapters one and two answer the question of why James was chosen as the protagonist of the narrative. In chapter one I look in detail at the literary construction of the martyrdom of James and problematize the development of the traditions. Chapter two then turns to a discussion of the figure of James as an authority in the developing Christian community. Chapters three and four are concerned with the literary classification of the text. Chapter three situates the First Apocalypse of James within the overarching genre of apocalyptic literature, and the specific sub-genre of gnostic apocalypses. Chapter four discusses how the text might be understood as a commission narrative while interrogating the lineage of descent beginning with the transmission of the revelation from James to Addai. Following this in chapter five I explore the cosmology of the text with particular attention to the ascent of the soul.

description: Peace education offers potential for transforming violent conflict into peace between groups in conflict. The research literature on conflict transformation theory and peace education has identified key assumptions for building long-term peace following violent conflict. The extent to which peace education programs have incorporated these theoretical notions, however, is not well known. This thesis explored the extent to which key theoretical insights from the literature on conflict transformation theory and peace education are incorporated in a prominent peace education program, Seeds of Peace. Data collection consisted of interviews with ten program staff members and written documentation produced by Seeds of Peace. Employing the analytical framework developed from a review of the literature, a comparison between theoretical notions and Seeds of Peace programming was done. Findings of this study highlight the extent to which there are gaps between theory and practice, and a case is made for the establishment of a more explicit connection between theory and practice. Furthermore, the thesis highlights the importance of further studies to address the research gap.
