['Die vielsprachige Seele Kakaniens : Übersetzen und Dolmetschen in der Habsburgermonarchie 1848 bis 1918']
[['In the last few decades, the discipline of Translation Studies has been characterized by a considerable increase of interdisciplinary approaches which both helped to sharpen its profiling and to promote its multilayered epistemological discussions. The contribution of this book to these developments is located on various levels. I claim that in view of its multifaceted forms, translation as practiced in the late Habsburg Empire to a high degree contributed to the construction of cultures in the pluri-cultural space of the Habsburg Monarchy: on the one hand, I have revealed the various layers of translation’s constructive character and then – on the basis of Pierre Bourdieu’s sociological framework – shed light on the various construction processes on behalf of detailed analyses which focus on the agents involved in these processes. These considerations are then reflected in the delineation of a model which I call the “pluri-cultural communication space of the Habsburg Monarchy”. In terms of methodology, I have drawn on post-colonial theoretical frameworks. On such a basis, I have sketched a concept of culture which aims to correspond to the hybrid constellations characteristic to vast parts of the Monarchy and which claims to detect the symbolic forms of ethnically articulated dominance. The metaphorically inspired translation concept developed in the wake of these reflections (“cultural translation”) results in conceptualizing a typology of various translation forms which claim to do justice to the complexity of the Monarchy’s translatorial practices in the continuum between “communication” and “translation”. Primarily on the basis of archival sources, the analysis covers the translatorial practice in the various ministries (“Commission of Terminology “,“Bureau of Redaction of the Imperial Law Gazette”, “Section of Ciphering and Translatorial Work”), in court (sworn interpreters), and in the diplomatic service, among others. On the other hand, I have worked on extensive corpora analyzing the translation flows both between various languages of the crown lands and with countries outside the Monarchy by adopting numerous parameters (focus: translations into German). Finally, the focus is laid on the translations from Italian, with a particular emphasis on laying bare the construction processes operating in the selection, production, distribution and reception of these translations.

['A dedicated endstation for waveguide-based x-ray imaging']
['X-ray microscopy has emerged as a powerful and versatile imaging technique in many fields of science over the last years, offering insights in opaque media at high spatial resolution. A major challenge remains the fabrication of suitable X-ray lenses, e.g., Fresnel zone plates or compound refractive lenses. In an alternative approach of a lensless imaging scheme the sample is illuminated by a coherent X-ray beam. The sample information is then reconstructed from the recorded diffraction signal by numerical iterative algorithms. Within this thesis the basics of lensless holographic imaging with X-Ray waveguides are summarised and extended to the concept of waveguide-based X-ray interferometry. The specific instrumentation required for the conceptual experiments of waveguide-based holographic imaging is explained and illustrated by the obtained results. Based on the results of these conceptual experiments a dedicated synchrotron endstation for waveguide-based holographic imaging was designed and built. The specifications and properties of the Kirkpatrick-Baez focussing mirrors and other mechanical and optical components are described in detail, along with the instrument control system and various available detectors. First commissioning results prove the imaging abilities of the presented endstation.']

Importantly, a conceptually new pulse resolved x-ray detection scheme, well exceeding the performance of present detector concepts, has been developed and is described in detail.'] ### GND ID: ['gnd:4035873-2', 'gnd:4150451-3', 'gnd:4178324-4', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A756720192'] ### GND class: ['Lipide', 'Doppelschicht', 'Röntgenstreuung'] <|eot_id|>

['A compositional framework for designing self-stabilizing distributed algorithms']
[['The proliferation of numerous computing devices in the various facets of life has remarkably elevated the premium placed on fault tolerance of the algorithms running on such devices. Self-stabilization is a novel method to provide non-masking fault tolerance. A distributed system is said to be self-stabilizing if and only if 1) it reaches a closed set of legal states in finite time, and 2) does not leave this set voluntarily. However, designing and proving convergence of a self-stabilizing system is not easy. We investigate whether the conditions under which component algorithms are self-stabilizing can be transcended while composing them. To that end, this dissertation presents a suite of compositional methods which can be used to compose self-stabilizing algorithms, though component algorithms themselves might be self-stabilizing under mutually incompatible conditions. <engl.>', 'Die zunehmende Verwendung verteilter Systeme im alltäglichen Leben für sicherheitskritische Anwendungen stellt besondere Anforderungen an deren Zuverlässigkeit.

['Motivational foundations of consumer behavior']
['This dissertation deals with the motivational foundations of consumer behavior. The dissertation utilizes insights mainly from motivational psychology, biology, and neuroscience to investigate why we are motivated to consume certain goods, but not others. In particular, the dissertation emphasizes that parts of our motivation can be understood in terms of needs and their deprivation. The dissertation contains three main chapters (4, 5, and 6). Chapters 4 and 5 deal with intertemporal choice and impulsive consumption. Chapter 4 presents a new intertemporal choice model and shows that impulsive choices can be understood by utilizing recent neuroscientific findings suggesting that cue-triggered “wanting” can be a reason for the occurrence of impulsive urges. When driven by cue-triggered “wanting”, individuals sometimes impulsively “want” rewards, although they do not necessarily “like” the rewards. Chapter 5 uses the cue-triggered “wanting” mechanism to explain that individuals oftentimes buy identity-relevant goods such as clothes in an impulsive fashion. The chapter argues that the “wanting”-“liking” dissociation can explain the regret that individuals sometimes perceive after having bought identity-related products on impulse. Based on the knowledge of the cue-triggered “wanting” mechanism, especially in context of identity-related consumption, the chapter presents implications for libertarian paternalistic policy advice. More precisely, the chapter illustrates how nudges can be used to either reduce unnecessary impulsive consumption or increase the frequency with which ethical goods are impulsively consumed. Finally, chapter 6 presents a formal model explaining the changes in consumer behavior over the long run based on needs and their deprivation patterns. The model explains, for example, the empirical regularity that expenditure shares devoted to food consumption decrease with rising income.']

['In dieser Arbeit wird die Bedeutung von Ressourcenaufbau und Traumakonfrontation in der Integrativen Traumatherapie IBP im Vergleich mit weiteren traumatherapeutischen Richtungen diskutiert. Nach Darlegung des historischen Hintergrundes der Traumaforschung und der Diagnostik der traumareaktiven Störungsbilder in DSM IV und ICD 10 werden neurobiologische Aspekte zum Verständnis des Verhaltens in überfordernden Situationen dargelegt. Im Weiteren werden die Integrative Traumatherapie IBP (ITT IBP) und ihre Grundlagen detaillierter beschrieben, sowie weitere traumatherapeutische Richtungen wie Somatic Experiencing, Psychodynamisch Imaginative Traumatherapie (PITT), Kognitive Verhaltenstherapie (KVT) bei PTBS, Prolonged Exposure und Eye Movement Desensitization and Reprocessing (EMDR) dargestellt. In der Folge wird die Wirksamkeit der vorgestellten traumatherapeutischen Konzepte aufgrund von Forschungsergebnissen sowie die Frage der Gewichtung von Ressourcenaufbau und Traumakonfrontation - auch auf dem Hintergrund der Neuroplastizität des menschlichen Hirns - diskutiert. In this thesis, the significance of resources development and trauma confrontation in Integrative trauma therapy IBP is discussed in comparison with other trauma-therapeutic methods.

['Essays on consumer choices relevant to climate change : stated preference evidence from Germany']
['One of the major challenges that our world faces today and in the future is human-induced climate change. The primary cause of global warming, leading to climate change, is the burning of fossil fuels for energy and transport, which increases the concentration of greenhouse gases in the atmosphere. Energy efficiency and renewable energy sources are considered by many as the proverbial "silver bullet" to avoid the worst climate change scenarios. However, the support for and success of any effort to improve energy efficiency and expand renewable energies strongly depends on preferences and choices of consumers. In four distinct but related essays, the present doctoral thesis examines consumer preferences for alternative-fuel vehicles and building energy retrofits. It makes use of data from two dedicated Germany-wide surveys, one of car buyers and the other of house owners. Each of these surveys included a discrete choice experiment, where respondents were faced with hypothetical choice situations. The car buyers were asked to select the car they preferred most from sets of seven vehicles with different fuel types. The house owners, on the other hand, first selected their preferred retrofit alternative from binary choice sets and then indicated whether they would actually undertake the selected retrofit activity if it were on the market. Similar choice experiments have been used before in transportation and energy research. But in contrast to previous studies, this work includes a wider range of alternative fuels and explicitly considers environmental benefits of energy retrofits. Based on the choice data, barriers to the widespread adoption of alternative-fuel vehicles and building energy retrofits are identified, and it is examined to what extent environmental aspects influence consumer choice behavior in Germany. The doctoral thesis confirms existing evidence on the impact of fuel availability on demand for alternative-fuel vehicles, primarily coming from North America, in the German context (Chapter 2). It makes important contributions to the growing, but heterogeneous literature that seeks to elicit willingness to pay for carbon abatements, carbon offsets, or climate policy in general (Chapters 3 and 4). Finally, it attempts to explain the persistent low retrofit rate in Germany and makes suggestions on how to stimulate energy retrofits in an effective and cost-efficient way (Chapter 5).']

To further test the validity and utility of the two proposed models, I apply the two theoretical frameworks to a case study of a tourism destination, Guilin, China. The case research reveals that Guilin has experienced path preformation, path creation, lock-in and a new turn of path creation phases of tourism area development. The interaction and coevolution of tourism products, sectors and institutional environments suggest that external environments, policy changes and product innovation are the main coevolutionary mechanisms for tourism development in Guilin over time.']

['Effekte von Titandioxidnanopartikeln auf den Nematoden Caenorhabditis elegans unter besonderer Berücksichtigung von UV-Strahlung']
[['Engineered nanoparticles (ENPs) are increasingly used in a variety of industrial and consumer products and will inevitably enter the aquatic environment. Modelling environmental emissions of nanoscale titanium dioxide (nTiO2) resulted in predicted sediments accumulation rates up to 1.4 mg/kg*year. Potential effects of ENPs on human health and the environment are still poorly understood. In comparison to their bulk scale counterparts, nanoparticles pose a higher risk to the environment for several reasons. First, their small size (< 100 nm) enables them to penetrate organisms and cells, where they can interfere with cellular processes. Also, due to their large surface area, nanoparticles have the potential to affect bioavailability and toxicity of co-existing contaminants like heavy metals or PAHs by acting as a carrier. For TiO2-particles, photocatalytic activity increases with increasing surface area, as this property depends strongly on the accessibility of the particles surface to the environment. In order to assess the nanoscale specific effects and the potential impacts of varying environmental conditions, this study addresses the following questions: 1) Does particle size affect the toxicity of TiO2 particles? 2) How does sunlight impact the toxicity of photocatalytically active nanoparticles? 3) Does nTiO2 interact with phenanthren as a common co-contaminant in sediments? 4) How does nTiO2 impact phenanthren as co-contaminant exposed to sunlight? The nematode Caenorhabditis elegans was used to determine the chronic toxicity of two different TiO2-materials: A 21 nm, nanoscale TiO2 (P25) and a 90 to 230 nm, bulkscale TiO2 (bTiO2: NM100). While agglomerating to a comparable secondary particle size of 300 to 1500 nm, only nTiO2 inhibited reproduction of C. elegans significantly with a LOEC of 10 mg/l and an EC50 > 100 mg/l, while no effects were observed for bTiO2. Results of Microscopy and Energy Dispersive X-Ray-analysis indicate that both materials are taken up by the intestinal tract of C. elegans. Further examination of the agglomeration of TiO2-particles in the gut of C. elegans showed that both materials caused a dysfunction of the defecation process by inhibiting feeding efficiency. Exposition to simulated solar radiation increased toxicity of nTiO2 to an EC50 of 53 mg/l, while no phototoxicity has been observed for bTiO2. Since nTiO2 produces more reactive oxygen species (ROS) than bTiO2, when measured as photo-degradation of methylene blue, the observed photoactivated effects of nTiO2 are likely due to oxidative stress. To test for a corresponding genetic response, expression of sod-3 was analyzed on mRNA and enzymatic level by using real-time PCR and a sod-3:gfp transgenic strain, respectively. Independent of the applied light conditions, nTiO2 did not impact sod-3 expression, suggesting that no ROS-production occurred within C. elegans cells. Therefore it was concluded that the nano-particles did not enter the cells and the observed phototoxicity was evoked by oxidative damage at the outer apical membrane of the intestinal cells, due to modes of action such as lipid and protein peroxidation. nTiO2 was not found to have a significant effect on the toxicity or bioavailability of phenanthrene, when measured as gene expression of cyp-35C1. In combined exposure with radiation, nTiO2 appears to block the impact of UV-light on the photo-sensitive PAH and decreases photo-toxicity. The results of this study highlight the importance of primary particle size and environmental parameters on the toxicity of TiO2 materials. Even though bTiO2 and nTiO2 agglomerate to the same secondary particle size in the test system, only nano-TiO2 is toxic to C. elegans. Missing evidence for cell internal effects of the photocatalytically active nTiO2 suggests that nanoparticles act extracellular by inducing oxidative damage of the epithelial membranes in the gut. Potential enhancement of nano-TiO2 toxicity by physico-chemical parameters stresses the necessity of further investigations into their ecotoxicological effects under different environmental conditions.', 'Der vielseitige Einsatz industriell gefertigter Nanopartikel in nahezu allen Industriezweigen wird zu einem zunehmenden Eintrag der Materialien in die Umwelt führen.

Document ### Title: ['Effekte von Titandioxidnanopartikeln auf den Nematoden Caenorhabditis elegans unter besonderer Berücksichtigung von UV-Strahlung'] ### Abstract: [['Engineered nanoparticles (ENPs) are increasingly used in a variety of industrial and consumer products and will inevitably enter the aquatic environment. Modelling environmental emissions of nanoscale titanium dioxide (nTiO2) resulted in predicted sediments accumulation rates up to 1.4 mg/kg*year. Potential effects of ENPs on human health and the environment are still poorly understood. In comparison to their bulk scale counterparts, nanoparticles pose a higher risk to the environment for several reasons. First, their small size (< 100 nm) enables them to penetrate organisms and cells, where they can interfere with cellular processes. Also, due to their large surface area, nanoparticles have the potential to affect bioavailability and toxicity of co-existing contaminants like heavy metals or PAHs by acting as a carrier. For TiO2-particles, photocatalytic activity increases with increasing surface area, as this property depends strongly on the accessibility of the particles surface to the environment. In order to assess the nanoscale specific effects and the potential impacts of varying environmental conditions, this study addresses the following questions: 1) Does particle size affect the toxicity of TiO2 particles? 2) How does sunlight impact the toxicity of photocatalytically active nanoparticles? 3) Does nTiO2 interact with phenanthren as a common co-contaminant in sediments? 4) How does nTiO2 impact phenanthren as co-contaminant exposed to sunlight? The nematode Caenorhabditis elegans was used to determine the chronic toxicity of two different TiO2-materials: A 21 nm, nanoscale TiO2 (P25) and a 90 to 230 nm, bulkscale TiO2 (bTiO2: NM100). While agglomerating to a comparable secondary particle size of 300 to 1500 nm, only nTiO2 inhibited reproduction of C. elegans significantly with a LOEC of 10 mg/l and an EC50 > 100 mg/l, while no effects were observed for bTiO2. Results of Microscopy and Energy Dispersive X-Ray-analysis indicate that both materials are taken up by the intestinal tract of C. elegans. Further examination of the agglomeration of TiO2-particles in the gut of C. elegans showed that both materials caused a dysfunction of the defecation process by inhibiting feeding efficiency. Exposition to simulated solar radiation increased toxicity of nTiO2 to an EC50 of 53 mg/l, while no phototoxicity has been observed for bTiO2. Since nTiO2 produces more reactive oxygen species (ROS) than bTiO2, when measured as photo-degradation of methylene blue, the observed photoactivated effects of nTiO2 are likely due to oxidative stress. To test for a corresponding genetic response, expression of sod-3 was analyzed on mRNA and enzymatic level by using real-time PCR and a sod-3:gfp transgenic strain, respectively.

['Socio-economic vulnerability to climate change : a regional assessment in the context of water stress and tourism development in north-eastern Morocco']
[['Water resources in north-eastern Morocco are increasingly under pressure from a growing human demand and a regional drying trend caused by changing climate patterns. Recently, water resources have reached or already fallen below critical limits. The human exploitation of water resources represents the main reason for an alarming decrease of freshwater resources: caused by population growth, high agricultural irrigation water needs, and the recent implementation of a water-intense tourism sector. The lack of appropriate policies to respond to these challenges determines regional vulnerability und puts socio-economic development at risk. The overarching research objective of this thesis is the identification of human and climateinduced rivers for increasing water stress in north-eastern Morocco with a focus on regional tourism development. With particular regard to climate change and to the water-intense regional development plans, it is necessary to analyse how this will influence the near-term water situation and water demand, respectively.

The technical part describes the design concept of an ultra-highvacuum test site with respect to some details, the procedure for setup and operation, and the description of implemented (sample holder, load lock system, sample storage, PVD, FT-IRAS, TPS, LEED) and further components. Some difficulties in the measuring technology and special features of the techniques used are discussed in detail; specifically the fragmentaion of NO in the quadrupole mass spectrometer is analysed. The scientific part describes the adsorption behaviour and the adsorbate site change due to laser irradiation for different platinum particles on alumina support. Variations in the substrate temperature during the preparation yield nano particles differing in properties like adsorbate site distribution, sensitivity for laser irradiation, and presumably their morphology.

['Vector valued Bohnenblust-Hille inequalities']

['Liberation of low molecular weight organic acids from sedimentary organic matter and their role on microbial activity']
['Low molecular weight organic acids (LMWOAs) are important nutrients for microbes. However, most LMWOAs do not exist freely in the environment but are bound to macromolecular organic matter, e.g. kerogen, lignite and coal. During burial and geological maturation of sedimentary macromolecular organic matter biological and abiological processes promote the liberation of LMWOAs into the surrounding sediment. Through this process, microbes in sedimentary subsurface environments are supplied with essential nutrients. To estimate the feedstock potential of buried macromolecular organic matter to many environments it is important to determine the amount of LMWOAs that are bound to such a matrix. However, high-pressure and high temperature are a key feature of deep subsurface environments, and these physical parameters have a profound influence on chemical reaction kinetics. Therefore it is essential for the estimation of the feedstock potential to generate high-pressure and high temperature for the liberation of LMWOAs to recreate true in-situ conditions. This work presents a newly developed, inexpensive incubation system for biological and geological samples. It allows the application of high-pressure and high temperature as well as a subsampling of the liquid phase without loss of pressure, thereby not disturbing the on-going processes. When simulating the liberation of LMWOAs from sedimentary organic matter, the newly developed incubation system produces more realistic results than other extraction systems like Soxhlet. The extraction products remain in the extraction medium throughout the extraction, influencing the chemical conditions of the extraction medium. Sub-bituminous coal samples from New Zealand as well as lignite samples from Germany were extracted at elevated temperature (90˚C) and pressure (5 MPa). The main LMWOAs released from these low rank coals were formate, acetate and oxalate. Extraction efficiency was increased by two to four times for formate, acetate and oxalate in comparison to existing extraction methods without pressurisation and with demineralised water. This shows the importance of pressure for the simulation of true in-situ conditions and suggests that the amount of bioavailable LMWOAs is higher than previously thought. With the increase in carbon capture and storage (CCS) and the enhanced recovery of oil and gas (EOR/EGR), more and more CO2 becomes injected into the underground. However, the effects of elevated concentrations of carbon dioxide on sedimentary organic matter are rarely investigated. As the incuabtion system allows the manipulation of the composition and partial pressure of dissolved gasses, the effect of highly gas-enriched (CO2, CO2/SO2, CO2/NO2; to simulate flue gas conditions) waters on the extraction yield of LMWOAs from macromolecular organic matter was evaluated. For sub-bituminous coal the concentrations of all LMWAOs decreased upon the addition of gas, irrespective of its composition, whereas for lignite formate always and acetate mostly increased, while oxalate decreased. This suggests an positive effect on the nutrient supply for the subsurface microbiota of lignite layers, as formate and acetate are the most common LMWOAs used for microbial metabolism. In terrestrial mud volcanoes (TMVs), sedimentary material is rapidly ascending from great depth to the surface. Therefore LMWOAs that were produced from buried macromolecular organic matter at depth are also brought up to the surface, and fuel heterotrophic microbial ecosystems at the surface. TMVs represent geochemically and microbiologically diverse habitats, which are supplied with organic substrates and electron acceptors from deep-seated hydrocarbon-generating systems and intersected shallow aquifers, respectively. The main electron donor in TMVs in Azerbaijan is sulphate, and microbial sulphate reduction leads to the production of a wide range of reduced sulphur species that are key players in several biological processes. In our study we estimated the effect of LMWOAs on the sulphur metabolising activity of microorganims in TMVs from Azerbaijan. The addition of a mixture of volatile fatty acids containing acetate and other LMWOAs showed significant positive response to the sulphate reduction rate (SRR) of samples of several mud volcanoes. Further investigations on the temperature dependency of the SRR and the characterisation of thermophilic sulphate-reducing bacteria (SRB) showed a connection between the deep hot subsurface and the surface']

It allows the application of high-pressure and high temperature as well as a subsampling of the liquid phase without loss of pressure, thereby not disturbing the on-going processes. When simulating the liberation of LMWOAs from sedimentary organic matter, the newly developed incubation system produces more realistic results than other extraction systems like Soxhlet. The extraction products remain in the extraction medium throughout the extraction, influencing the chemical conditions of the extraction medium. Sub-bituminous coal samples from New Zealand as well as lignite samples from Germany were extracted at elevated temperature (90˚C) and pressure (5 MPa). The main LMWOAs released from these low rank coals were formate, acetate and oxalate. Extraction efficiency was increased by two to four times for formate, acetate and oxalate in comparison to existing extraction methods without pressurisation and with demineralised water. This shows the importance of pressure for the simulation of true in-situ conditions and suggests that the amount of bioavailable LMWOAs is higher than previously thought. With the increase in carbon capture and storage (CCS) and the enhanced recovery of oil and gas (EOR/EGR), more and more CO2 becomes injected into the underground. However, the effects of elevated concentrations of carbon dioxide on sedimentary organic matter are rarely investigated. As the incuabtion system allows the manipulation of the composition and partial pressure of dissolved gasses, the effect of highly gas-enriched (CO2, CO2/SO2, CO2/NO2; to simulate flue gas conditions) waters on the extraction yield of LMWOAs from macromolecular organic matter was evaluated. For sub-bituminous coal the concentrations of all LMWAOs decreased upon the addition of gas, irrespective of its composition, whereas for lignite formate always and acetate mostly increased, while oxalate decreased. This suggests an positive effect on the nutrient supply for the subsurface microbiota of lignite layers, as formate and acetate are the most common LMWOAs used for microbial metabolism. In terrestrial mud volcanoes (TMVs), sedimentary material is rapidly ascending from great depth to the surface. Therefore LMWOAs that were produced from buried macromolecular organic matter at depth are also brought up to the surface, and fuel heterotrophic microbial ecosystems at the surface. TMVs represent geochemically and microbiologically diverse habitats, which are supplied with organic substrates and electron acceptors from deep-seated hydrocarbon-generating systems and intersected shallow aquifers, respectively. The main electron donor in TMVs in Azerbaijan is sulphate, and microbial sulphate reduction leads to the production of a wide range of reduced sulphur species that are key players in several biological processes. In our study we estimated the effect of LMWOAs on the sulphur metabolising activity of microorganims in TMVs from Azerbaijan. The addition of a mixture of volatile fatty acids containing acetate and other LMWOAs showed significant positive response to the sulphate reduction rate (SRR) of samples of several mud volcanoes. Further investigations on the temperature dependency of the SRR and the characterisation of thermophilic sulphate-reducing bacteria (SRB) showed a connection between the deep hot subsurface and the surface'] ### GND ID: ['gnd:1027585337', 'gnd:1074045769', 'gnd:4659394-9', 'https://www.tib.eu/de/suchen/id/TIBKAT%3A773527885'] ### GND class: ['Strecker, Manfred', 'Sauer, Patrick', 'Bodenmikrobiologie'] <|eot_id|>

['Friction interface mechanics and self-induced vibrations']
[['Vibrations in braking systems have been studied since the beginning of the last century and despite several insights, still many phenomena, particularly in the area of friction induced vibrations, are not fully understood. The objective of the actual study was the identification of the complex dynamics in the friction interface of a dry friction brake system. In this context, particular consideration was given to the generation of instabilities and brake squeal. In work presently being undertaken, irregular vibration data of a dry friction brake in non-squealing condition were collected with sampling rates above 200 kHz. The resulting time series were subjected to linear, nonlinear and statistical analyses and in particular with regard to the involved multi-scale dynamics. At first, topological examination of the friction surfaces disclosed the microscale characteristics; visual inspections of the coating, generated on the brake disk insights in to the friction interface transformations. Secondly, linear investigations of the vibration data in the frequency domain provided first impressions of the friction interface: while the spectral frequency distribution remains mostly independent from mechanic parameters, it is essentially controlled by the pad formulation and physical and chemical interface transformations during the experiment. Thirdly, the data were explored on the basis of recurrence analysis and together with the estimation of dimensionality the phase space was reconstructed. Evidently, the irregular vibration states of friction brakes in non-squealing condition are strongly controlled both by apparently steady and disruptive phenomena (intermittency). The duration between the states was typically in the range of milliseconds. Phase space reconstruction and largest Lyapunov coefficient estimation indicated thereby that these phenomena are dominated more by low-dimensional chaotic deterministic dynamics than by high-dimensional stochastic processes. In the following, characteristic measures of the recurrence quantification analysis have been extracted which disclosed an interrelation with the noise propensity of the overall brake system. Finally, statistical studies of the distribution of vibration increments on the basis of probability density functions concluded the evaluation of the experiments. The distribution analyses disclosed the non-Gaussian characteristic of the vibration signals under steady sliding whereby the deviation from the normal distribution depends on the corresponding scale. Furthermore, the vibration during sliding in non-squealing condition is effectively generated by dynamics on different scales. And beyond that, the difference between the measured and the Gaussian distribution suggests a correlation between the squeal propensity and the deviation under consideration.', 'Vibrationen in Bremssystemen sind seit Anfang des letzten Jahrhunderts untersucht worden und obwohl zahlreiche Erkenntnisse über die mechanischen Zusammenhänge gewonnen wurden, sind die auftretenden Phänomene, insbesondere im Bereich der reibungsinduzierten Schwingungen, nicht vollständig erklärbar.

['Fate and transport modeling of cohesive sediment and sediment-bound HCB in the middle Elbe river basin']
[['Chemical contamination of waterways and floodplains is a pervasive environmental problem that threatens aquatic ecosystems worldwide. The Elbe River is the third largest river in Central Europe, starting in the Czech Republic and running through Dresden and Hamburg before empting into the North Sea. Due to extensive historical contamination and redistribution of contaminated sediments throughout the basin, the Elbe River transports significant loads of contaminants downstream, particularly during flood events. The high mobility of the fine-grained sediments within the basin means that sections of the Elbe River are unlikely to achieve the goals of the Water Framework Directive by 2015 (Zebisch et al., 2005). This study focuses on transport of cohesive suspended sediment and Hexachlorobenzene (HCB), a contaminant of concern in the Elbe River Basin. Sediment-sorbed concentrations of HCB significantly exceed environmental quality criteria and the Elbe River Community (FGG Elbe) has stated that a reduction of 98 % of the sediment-bound HCB load (relative to 2006) would be necessary to achieve all management objectives (FGG Elbe, 2009). To better understand the fate and transport of cohesive sediments and sediment-sorbed HCB, a hydrodynamic and sediment transport model for the reach of the Elbe River basin between Dresden and Magdeburg was developed. An evaluation of impact of the numerous groynes, or spit dykes, along the Elbe, was integrated into the modeling effort. A quasi-2D model, which includes both a 1D representation of the Elbe between Dresden and Magdeburg and the Elbes floodplains between Torgau and Magdeburg, was developed. The model was calibrated and validated for hydrodynamics, cohesive suspended sediment and sediment-sorbed HCB. A 2D flexible mesh model was developed between Aken and Barby to evaluate the impacts of groyne fields.

Document ### Title: ['Fate and transport modeling of cohesive sediment and sediment-bound HCB in the middle Elbe river basin'] ### Abstract: [['Chemical contamination of waterways and floodplains is a pervasive environmental problem that threatens aquatic ecosystems worldwide. The Elbe River is the third largest river in Central Europe, starting in the Czech Republic and running through Dresden and Hamburg before empting into the North Sea. Due to extensive historical contamination and redistribution of contaminated sediments throughout the basin, the Elbe River transports significant loads of contaminants downstream, particularly during flood events. The high mobility of the fine-grained sediments within the basin means that sections of the Elbe River are unlikely to achieve the goals of the Water Framework Directive by 2015 (Zebisch et al., 2005). This study focuses on transport of cohesive suspended sediment and Hexachlorobenzene (HCB), a contaminant of concern in the Elbe River Basin. Sediment-sorbed concentrations of HCB significantly exceed environmental quality criteria and the Elbe River Community (FGG Elbe) has stated that a reduction of 98 % of the sediment-bound HCB load (relative to 2006) would be necessary to achieve all management objectives (FGG Elbe, 2009). To better understand the fate and transport of cohesive sediments and sediment-sorbed HCB, a hydrodynamic and sediment transport model for the reach of the Elbe River basin between Dresden and Magdeburg was developed. An evaluation of impact of the numerous groynes, or spit dykes, along the Elbe, was integrated into the modeling effort. A quasi-2D model, which includes both a 1D representation of the Elbe between Dresden and Magdeburg and the Elbes floodplains between Torgau and Magdeburg, was developed. The model was calibrated and validated for hydrodynamics, cohesive suspended sediment and sediment-sorbed HCB. A 2D flexible mesh model was developed between Aken and Barby to evaluate the impacts of groyne fields. The 1D and 2D flexible mesh model allowed for quantification the impact of groyne fields on sediment travel time. Simulations were run to evaluate sediment travel time during high water events. The impact analysis of Elbe groyne fields showed that they reduce transport times of cohesive material and associated sediment sorbed contaminants approximately 15 % during average hydrodynamic conditions. The quasi 2D model was run under a variety of discharge scenarios to calculate the extent of transport of sediment and sediment-bound HCB to the floodplains (337 km2) between Torgau and Magdeburg during nine high water events exceeding mean high discharge (MHQ) between 1998 and 2011.

['Die Rolle des Gens Disrupted-in-Schizophrenia-1 (DISC1) während der tangentialen Migration kortikaler Interneurone der Maus']
['The gene “Disrupted-in-Schizophrenia-1” (DISC1) got into the scientific focus of Psychiatrists and Neurobiologists at the beginning of the century. A disruption of this gene was discovered within members of a Scottish family, who have a higher predisposition to develop schizophrenia spectrum disorders (Chubb et al., 2008). The DISC1 gene encodes a protein, which showed multiple functions in neuronal cells, e.g. during proliferation, migration and positioning of neurons or the development of synapses. In this doctoral thesis the role of DISC1 during neuronal migration, especially interneuron migration was examined. These cells make up around 20% of all cortical neurons, thus representing a minority of neurons in the cortex. However, they are highly diverse in morphological as well as functional aspects and are necessary for the correct balance between excitation and inhibition in the brain. Thus it has been described, that patients with epilepsy, autism or schizophrenia display deficits in cortical interneurons. (Le Magueresse and Monyer, 2013) In the present study it has been shown, that DISC1 is necessary for the correct tangential migration of interneurons in mice. The gene is expressed at embryonic stage E14.5 in precursor cells of parvalbuminergic interneurons deriving from the MGE. Using RNA interference techniques it was possible to successfully down regulate the DISC1 expression in those neurons, thereafter they react with a reduced migratory behavior. The dynamic observation of DISC1-deficient interneurons showed that the complex process of the saltatory movement of these cells was disturbed. This process is realized by cytoskeletal components and it was found that the reorganization of the actin cytoskeleton in DISC1-deficient interneurons was incorrect. In addition to the migration defect examined in vitro, this scenario could be reproduced in vivo using in utero electroporation to transfect MGE-derived interneurons with DISC1 or control miRNA. These experiments showed that fewer cells reached the cortex if they were transfected with DISC1-miRNA compared to the transfection with control constructs. These findings provide a possible link between clinical studies reporting alterations of cortical interneurons in schizophrenic patients and the current notion of schizophrenia as a neurodevelopmental disorder (Lewis and Levitt, 2002).']

Their work demands; perception of growing work-related uncertainties, coping strategies, perceived social support, expectancies and subjective values in work and further education domains and postgraduate intentions were assessed over two waves. A mediation relationship was hypothesized between work demands and postgraduate intentions through expectancies and subjective values. In addition, it was expected that engagement and disengagement coping strategies and perceived social support would moderate the relationships between work demands and expectancies and subjective values. Regression results revealed no direct relationship between work demands and postgraduate intentions but a successful mediation through the student’s expectancies. Thus, work uncertainties affect student’s assessments of their abilities and success expectations, which, in turn, are an indicator of whether or not a student intends to further their education. Other results indicate that, engagement coping moderated the mediation relationship between work demands and education domain expectancies whereas, disengagement coping moderated the relationship between work demands and work domain expectancies.

['Fagus sylvatica in temperate decidous forests differing in tree special diversity-effects on the soil microbial community and complementary resource use']
['The increasing loss of biodiversity prompts the need for a greater understanding of ecosystem functioning, particularly in forest ecosystems. The present work investigates if increased proportions of different deciduous tree species in beech forest ecosystems affect the microbial community due to an increase in litter quality (leaf and root litter) during different seasons. Furthermore, this study focused on whether the increase of complementarity effects with increasing plant diversity observed in long-term grassland experiments can also be seen in species-rich forest ecosystems. Using microbial phospholipid fatty acids (PLFAs), the microbial communities from topsoils in different forest sites in the Hainich National Park, Germany, were analysed. In addition, we used the hydrogen isotopic signature (\uf064D, deuterium) of throughfall, soil water and n-alkanes from sun and shade leaf lipids to investigate the water use strategy of Fagus sylvatica during a period of drought. The results provide evidence that competition in the rooting zone by other tree species promotes strategies of drought avoidance in F. sylvatica, and also show complementary water use. Microbial communities are strongly influenced by abiotic controls, however species-specific tree characteristics affected the microbial community, especially in the photosynthetically active period when decomposition rates and root activity are highest. Our results suggest that a dense root network in association with arbuscular mycorrhizal fungi strongly supported microbial growth in the more diverse forest stands. It can be concluded that in species-rich forest ecosystems complementary resource use plays a crucial role for biotic interactions and ecosystem functioning, in particular maintaining the coexistence of different trees species.']

['Rationalizing myth in antiquity']
["The Greek myths are characteristically fabulous; they are full of monsters, metamorphoses, and the supernatural. However, they could be told in other ways as well. This volume charts ancient dissatisfaction with the excesses of myth, and the various attempts to cut these stories down to size by explaining them as misunderstood accounts of actual events. In the hands of ancient rationalizers, the hybrid forms of the Centaurs become early horse-riders, seen from a distance; the Minotaur the result of an illicit liaison, not an inter-species love affair; and Cerberus, nothing more than a notorious snake with a lethal bite. Such approaches form an indigenous mode of ancient myth criticism, and show Greeks grappling with the value and utility of their own narrative traditions. Rationalizing interpretations offer an insight into the practical difficulties inherent in distinguishing myth from history in ancient Greece, and indeed the fragmented nature of myth itself as a conceptual entity. By focusing on six Greek authors (Palaephatus, Heraclitus, Excerpta Vaticana, Conon, Plutarch, and Pausanias) and tracing the development of rationalistic interpretation from the fourth century BC to the Second Sophistic (1st-2nd centuries AD) and beyond, 'Rationalizing Myth in Antiquity' shows that, far from being marginalized as it has been in the past, rationalization should be understood as a fundamental component of the pluralistic and shifting network of Greek myth as it was experienced in antiquity"]

This study design made it possible to address the following objectives in the present thesis: to understand how soil microbial biomass, microbial community composition, and enzyme activities are influenced by grassland management and soil properties across the regional scale, to investigate enzyme activities and nutrient supply and demand for whole soil profiles in forests, and to evaluate the proportion of the total variance in enzyme activities that can be attributed to large scale differences between regions, long term forest management, and soil properties in different soil horizons, and to assess the organic carbon storage and radiocarbon signatures in three density fractions of forest and grassland sites under diverse management practices and soil properties in different regions. Overall, it can be concluded that soil microbial biomass, microbial community composition, enzyme activities, organic carbon storage and turnover in density fractions were more affected by soil properties than by forest and grassland management practices at the regional scale. Further, the results presented here highlight the need for large scale studies including different regions and their environmental conditions in order to draw general conclusions about the impact of land management and soil properties on soil microbial communities and organic carbon storage.

['Selbstkonzeptimmunisierung im Jugendalter']
[['Self-concept immunization denotes the adaptive up- and downgrading of the diagnostic value of particular skills for a general self-concept domain - according to the perceived levels of competence in these skills. Up to now theoretical attention was paid to the process within the field of life-span developmental psychology, especially within the context of older age. Within a series of empirical studies with participants from early adulthood to old age, its existence, specific mode of functioning and defensive functionality have been well documented in regards to the maintenance of a stable self, confronted with age(ing)-typical limitations and losses. The present study now introduces new areas of focus. First, an expansion of the age groups that were studied is intended to increase the understanding of the process and its development across wide parts of the lifespan. Second, the question will be addressed if self-concept immunization can adequately contribute to the complex task of identity construction in adolescence. For these purposes, three empirical studies are presented. Study 1 is a broad-based, correlative study, which will beyond testing hypotheses also pursue explorative issues. Adolescents and young adults within a large age spectrum (N = 200, 10-24 years, M = 16.81, SD = 3.27) were surveyed regarding a number of heterogeneous content areas (intelligence, athleticism, independence, courage, reliability, attractiveness). The focus was on the one hand on the development of self-concept immunization within the context of the developing self-concept structure and on the other hand on bivariate and moderating connections between self-concept immunization and self-esteem and measures of subjective well-being. Study 2 (N = 278, 11-24 years, M = 15.45, SD = 3.33) contains an experimental design.

Document ### Title: ['Selbstkonzeptimmunisierung im Jugendalter'] ### Abstract: [['Self-concept immunization denotes the adaptive up- and downgrading of the diagnostic value of particular skills for a general self-concept domain - according to the perceived levels of competence in these skills. Up to now theoretical attention was paid to the process within the field of life-span developmental psychology, especially within the context of older age. Within a series of empirical studies with participants from early adulthood to old age, its existence, specific mode of functioning and defensive functionality have been well documented in regards to the maintenance of a stable self, confronted with age(ing)-typical limitations and losses. The present study now introduces new areas of focus. First, an expansion of the age groups that were studied is intended to increase the understanding of the process and its development across wide parts of the lifespan. Second, the question will be addressed if self-concept immunization can adequately contribute to the complex task of identity construction in adolescence. For these purposes, three empirical studies are presented. Study 1 is a broad-based, correlative study, which will beyond testing hypotheses also pursue explorative issues. Adolescents and young adults within a large age spectrum (N = 200, 10-24 years, M = 16.81, SD = 3.27) were surveyed regarding a number of heterogeneous content areas (intelligence, athleticism, independence, courage, reliability, attractiveness). The focus was on the one hand on the development of self-concept immunization within the context of the developing self-concept structure and on the other hand on bivariate and moderating connections between self-concept immunization and self-esteem and measures of subjective well-being. Study 2 (N = 278, 11-24 years, M = 15.45, SD = 3.33) contains an experimental design. With the help of a research paradigm that was derived from Terror Management Theory, the indications of immunizing processes that were found correlatively in Study 1 are to be secured against alternative explanations. With the help of a longitudinal design, Study 3 will on the one hand illustrate the process of self-concept immunization and on the other hand study the functionality of immunizing processes within a natural setting.

['Analysis and management of low flows in small catchments of Brandenburg, Germany']
['Water management and environmental protection is vulnerable to extreme low flows during streamflow droughts. During the last decades, in most rivers of Central Europe summer runoff and low flows have decreased. Discharge projections agree that future decrease in runoff is likely for catchments in Brandenburg, Germany. Depending on the first-order controls on low flows, different adaption measures are expected to be appropriate. Small catchments were analyzed because they are expected to be more vulnerable to a changing climate than larger rivers. They are mainly headwater catchments with smaller ground water storage. Local characteristics are more important at this scale and can increase vulnerability. This thesis mutually evaluates potential adaption measures to sustain minimum runoff in small catchments of Brandenburg, Germany, and similarities of these catchments regarding low flows. The following guiding questions are addressed: (i) Which first-order controls on low flows and related time scales exist? (ii) Which are the differences between small catchments regarding low flow vulnerability? (iii) Which adaption measures to sustain minimum runoff in small catchments of Brandenburg are appropriate considering regional low flow patterns? Potential adaption measures to sustain minimum runoff during periods of low flows can be classified into three categories: (i) increase of groundwater recharge and subsequent baseflow by land use change, land management and artificial ground water recharge, (ii) increase of water storage with regulated outflow by reservoirs, lakes and wetland water management and (iii) regional low flow patterns have to be considered during planning of measures with multiple purposes (urban water management, waste water recycling and inter-basin water transfer). The question remained whether water management of areas with shallow groundwater tables can efficiently sustain minimum runoff. Exemplary, water management scenarios of a ditch irrigated area were evaluated using the model Hydrus-2D. Increasing antecedent water levels and stopping ditch irrigation during periods of low flows increased fluxes from the pasture to the stream, but storage was depleted faster during the summer months due to higher evapotranspiration. Fluxes from this approx. 1 km long pasture with an area of approx. 13 ha ranged from 0.3 to 0.7 l\\s depending on scenario. This demonstrates that numerous of such small decentralized measures are necessary to sustain minimum runoff in meso-scale catchments. Differences in the low flow risk of catchments and meteorological low flow predictors were analyzed. A principal component analysis was applied on daily discharge of 37 catchments between 1991 and 2006. Flows decreased more in Southeast Brandenburg according to meteorological forcing. Low flow risk was highest in a region east of Berlin because of intersection of a more continental climate and the specific geohydrology. In these catchments, flows decreased faster during summer and the low flow period was prolonged. A non-linear support vector machine regression was applied to iteratively select meteorological predictors for annual 30-day minimum runoff in 16 catchments between 1965 and 2006. The potential evapotranspiration sum of the previous 48 months was the most important predictor (r²=0.28). The potential evapotranspiration of the previous 3 months and the precipitation of the previous 3 months and last year increased model performance (r²=0.49, including all four predictors). Model performance was higher for catchments with low yield and more damped runoff. In catchments with high low flow risk, explanatory power of long term potential evapotranspiration was high. Catchments with a high low flow risk as well as catchments with a considerable decrease in flows in southeast Brandenburg have the highest demand for adaption. Measures increasing groundwater recharge are to be preferred. Catchments with high low flow risk showed relatively deep and decreasing groundwater heads allowing increased groundwater recharge at recharge areas with higher altitude away from the streams. Low flows are expected to stay low or decrease even further because long term potential evapotranspiration was the most important low flow predictor and is projected to increase during climate change. Differences in low flow risk and runoff dynamics between catchments have to be considered for management and planning of measures which do not only have the task to sustain minimum runoff.']

['Synthese, Charakterisierung und Reaktivität von silylkationischen Lewis-Paaren']
[['In the present thesis it was possible to transfer the concept of frustrated Lewis pairs to silylcationic systems. Behavior, properties and reactivity of a variety of intra- and intermolecular silylcationic Lewis pairs were examined both experimentally and by quantum chemistry. The most important parameters, which influence the behavior and reactivity of silylcationic Lewis pairs, were identified. The enormous reactivity of such intermolecular Si/P pairs was shown by their reactions with dihydrogen, CO2 and C-F bonds in an impressive manner. First steps towards silylcationic Lewis pairs applying other bases (e.g.carbenes, silylenes) were also taken successfully. It was possible to generate the first germylcationic Lewis pair and to study its reactivity towards dihydrogen. On top of that, first insights into the activation of H2 solely by a pure silylcation in absence of an external Lewis base could be obtained. <engl.>', 'Im Rahmen der Arbeit konnte das Konzept der frustrierten Lewis Paare auf silylkationische Systeme übertragen werden.

['Polymeromics : structural elucidation of macromolecules via tandem mass spectrometry utilizing various ionization techniques']
['The main objective of the presented thesis was to investigate the applicability of mass spectrometry (MS)-based techniques for the analysis of polymers. A variety of MS and tandem MS (MS/MS) techniques were utilized to gain accurate structural information from intricate macromolecular structures and to achieve the fragmentation behavior of several synthetic polymer classes such as various poly(2-oxazoline)s (POx), poly(ethylene imine)s (PEI), and poly(methyl acrylate)s (PMA). MS techniques was used to gain information about their molar mass distributions, PDI values, monomer units, macromolecular architectures, side chain substituents and end-group functionalities. ESI, APCI and MALDI MS were utilized in order to comprehensively analyze synthetic polymers in systematic comparison studies. Additional information about the fragmentation behavior and the stabilities of macromolecules were gained from energy-dependent CID experiments. Survival yield (SY) method was applied to several polymers for the first time and SY curves were shown as a useful tool to correlate the macromolecular structure of polymers to their fragmentation behavior. Moreover, energy dependent CID experiments were also performed successfully to analyze the gas-phase stabilities of various metal complexes. The relative complex stabilities were estimated depending on the nature of the coordinated ligands used in the synthesis of investigated metal complexes. The hyphenation of LC and MS techniques for comprehensive polymer characterization was shown for the case of poly(2-ethyl-2-oxazoline)s (PEtOx). The characterization of PEtOx copolymers were accomplished by the coupling of a two dimensional chromatography (2D) technique (LCCC x SEC) to MS and MS/MS techniques. An important approach for the evaluation of the MSn data by a special interpretation software was described and the field of “Polymeromics” was introduced in detail with a number of examples.']

['Quantum random walks in waveguide lattices']
['Random processes are ubiquitous in the natural world as well as in man-made environments. While classical random walks may behave highly complex or even chaotic, there outcome can, in principle, always be predicted from the parameters of the system and the initial conditions. In the realm of quantum mechanics, however, this is not possible as the underlying wave mechanics leads to intrinsically indeterministic outcomes. Moreover, if multiple indistinguishable particles are subjected to such a quantum random walk, their exchange symmetry causes quantum interference, thereby enriching the dynamics of the system even further. In this work, quantum random walks of pairs of indistinguishable photons, the quanta of light, are investigated. Networks of coupled optical waveguides are chosen as the experimental platform of choice, offering a high degree of coherence and versatility. In these photonic lattices, light propagates along one spatial dimension, whereas the individual waveguides are connected by evanescent coupling in the transverse dimensions. In particular, it is investigated how the various degrees of freedom, which are available in such photonic lattices, affect the trajectories in the quantum walks and their complexity. It is shown how the facilitation of both transverse dimensions allows for much richer quantum walks with properties unencountered in planar arrangements. But even if just a single transverse dimension is available, the coupling properties of the lattice along this dimension are a potent degree of freedom, which can be used to manipulate the quantum walk. Finally, an experimental technique is developed which enables a convenient characterisation of the expected quantum walk in an arbitrary waveguide lattice by classical light. The thesis concludes with a summary of the results and an outlook onto further developments in the field.']

['Combinatorial screening of functional polymers for organic electronics via inkjet printing']
['Inkjet printing represents a solution deposition technique that is characterized by its non-contact, material-efficient and reproducible processing. It is, however, a long way to gain a full understanding of the complete drying process, since the process conditions as well as the ink properties correlate in a complex relation with the final device properties. For inkjet printing, all solute parameters have a significant influence on the preparation of the printed patterns, which makes the ink development crucial. Important factors include the contact angle, ink viscosity and surface tension as well as the nozzle diameter. By using multiple print heads, a high speed production of thin films can be performed. Therefore, inkjet printing can be used as a R2R coating technique. However, for the application of inkjet printing in a commercial available device, there are many challenges to overcome, which is the reason why inkjet printing is up to now mainly used in scientific research environment. For a detailed understanding of the preparation techniques as well as to evaluate whether inkjet printing has the potential for producing efficient devices, the drying processes and resulting film morphologies need to be well understood. This thesis provides an overview of methodical investigations of ink characteristics, printing conditions and final film properties. In particular, the possibility to integrate inkjet printing into a combinatorial screening workflow evolves inkjet printing to a notable method for an efficient screening of new materials for organic electronics applications like organic photovoltaics (OPVs), organic light emitting diodes (OLEDs) and organic radical batteries (ORBs).']

['The toxic and therapeutic properties of Carbon monoxide (CO) are close together. However, the toxic properties of CO are far better known than the therapeutic applications. The low solubility in aqueous media and the lack of selectivity of free carbon monoxide are problematic for a specific therapeutic use.

By CORMs are often at transition metal carbonyl compounds, which are inactivated by the CO coordination to the metal center. In solid state of these complexes, a dose control of CO is possible. The present work focuses on the synthesis and characterization of ruthenium and manganese carbonyl complexes.
