description: Parasitism (including bioeroders of living bivalve shells) may modify optimal foraging models by altering the relationship between energy exerted and reward gained in acquiring prey resources. Boring sponges of the family Cliona burrow into calcareous material, including the shells of the Eastern Oyster Crassostrea virginica, and create extensive tunnels and galleries. To consider the effects of boring sponge infestation on predator-prey interactions, I calculated the reward/effort ratio of infested and healthy oysters using dry tissue mass (generally unaffected by sponge infestation) and crushing force (generally lower for sponge-infested oysters). These data suggest that crab predators should attack larger, heavily infested individuals. However, two types of feeding trials did not yield a clear pattern of crab prey preference for sponge-infested oysters. A preference may not have been observed because stone crabs are opportunistic predators with very strong chelipeds. Conversely, the relationship between boring sponge, oysters, and oyster predators may be convoluted.

description: The intuitive understanding of contact bodies is based on the geometry and adjoining surfaces. A powerful approach to solve the contact problem is to take advantage of the geometry of an analyzed object and describe the problem in the best coordinate system. This book is a systematical analysis of geometrical situations leading to contact pairs: suface-to-surface, curve-to-surface, point-to-surface a.s.o. resultingin the corresponding computational algorithms to solve the contact problem.

description: With increasing advancements in information and manufacturing technologies, there is an ever‑growing need for innovative integration and application of computational design and robotic fabrication in architecture. Hybrid Intelligence in Architectural Robotic Materialization (HI-ARM) provides methods and frameworks that target this need. HI-ARM introduces methodologies and technologies that incorporate computational, fabrication and material intelligence in integrated design-to-robotic-production workflows. The intelligence is explored at multiple architectural scales (Macro, Meso, Micro) through hybridization of building processes or multi-mode robotic production and multi-materiality. Porosity, Hybridity, and Assembly are introduced as main constituents for materialization frameworks relying on computational design and robotic production. These are tested in a series of original experiments that are presented in this thesis together with four peer-reviewed published papers discussing the process of developing integrated design-to-production methodologies in detail. The contributions show how both architectural materialization processes and building products can be customized in different phases and scales. Moreover, the developed discourse and definitions address the impacts of this research through the lenses of computation and automation in research, education, and practice in the fields of Architecture, Engineering, and Construction.

description: The synthesis of desepoxy-tedanolide C was accomplished and provided experimental evidence on the configuration of tedanolide C. The reported chemical shifts and coupling constants point to a configuration different from the published structure and analogous to the structures of the other members of this family of natural products. The key step is a Kiyooka aldol protocol for the stereoselective synthesis of the tertiary alcohol flanked by three additional oxygenated carbon atoms. Furthermore, two additional aldol reactions and a Julia–Kocienski olefination were used to assemble the carbon framework.

description: Dieser Beitrag analysiert die Geschichte der Turfan-Forschung unter zwei Aspekten: Erstens war die Archäologie eine Form von kulturimperialistischer Machtpolitik, die sich in der konfliktreichen Aufteilung von Grabungssphären zwischen deutschen, russischen, französischen und britischen Wissenschaftlern niederschlug. Zweitens war die Suche nach der ‚Urheimat‘, die hinter diesen Expeditionen stand, eine Suche nach der eigenen kulturellen Identität. Zusammenfassen lassen sich diese beiden Aspekte in der These, dass die Wandermythen der Turfan-Forschung unterschiedliche und historisch wandelbare Identitätsentwürfe katalysierten: Die aufgefundenen Objekte ließen sich aufgrund ihrer Interpretationsoffenheit sowohl in kosmopolitischen, also auch völkischen Entwürfen von Zivilisation und Kultur verorten.
description: This essay investigates the history of Turfan research during the German Empire. Two points stand on center stage: Firstly, archaeology can be considered as one type of imperialist power politics in a cultural sense. Conflicts on the spot arose between German, Russian, French, and British archaeologist, since explorers of each nation intended to occupy spaces of excavation. Secondly, the quest for the ‘Urheimat’, which was the leitmotif of these expeditions, was also a quest for the cultural identity of the nation. This essay argues that myths on historical migration defined diverse and historically changeable concepts of identity. The archaeological objects needed to be interpreted at first, and this process opened up possibilities to locate the relicts of Turfan in cosmopolitan, but also in völkisch and racial concepts of culture and civilization.

description: Numerous actors have been involved in the planning of the port and city of Naples. National and local authorities—namely central government, the Region, the Municipality of Naples, and the Port Authority—act upon the port at different scales, according to diverging interest and by using different planning tools. Each entity has different spatial claims and contrastive views on what port city integration can be. Their diverse goals have led port and city to develop into separate entities, from a spatial, cultural, economic as well as administrative perspective. The different scopes of their planning are particularly visible in the areas at the intersection of land and water, where the relationship is characterized by waiting conditions across different dimensions and scales. The separation between port and city in Naples originates from history. This PhD thesis looks at the past as a resource, sometimes as a problem in the way it produces inertia, but certainly as a heritage made of signs, traces, and cultures, written and rewritten on the urban palimpsest. Using and challenging the concept of path dependence—defined here as a resistance by institutions and people to change patterns of behavior and to repeat previous decisions and experiences—this PhD thesis argues that in order to overcome inertia, it is important to recognize the interests and spatial claims of all the stakeholders involved port city planning and to identify shared goals and values as a foundation for future design.

description: 3D geological modelling is becoming an effective tool for communication and development of geological understanding. This is due to increased computer performance and availability of improved geological modelling software. 3D geological modelling technology has reached the stage where it can be implemented in regionally extensive and geologically complex settings, with the ability to achieve geological insight beyond what could otherwise have been gained through 2D investigations alone. Insight includes better constrained fault and horizon topologies, refined fold geometries, improved understanding of tectonic processes, and characterization of deformational events. By integrating field observations, aeromagnetic maps, and 3D modelling techniques in the northern Labrador Trough, a regionally extensive and structurally complex geological environment, regional faults geometries and topological relationships were refined. Additionally, a new fault, the Ujaralialuk Fault, and two shear zones were interpreted. During modelling, several challenges were identified, including higher computational costs for regionally extensive models, sparse 3D constraints, algorithmic limitations related to complex geometries, and the large investment of time and effort required to produce a single model solution. A benefit of this investigation is that new insight was also gained for a greenfields region which may assist future exploration efforts. Developing 3D models in challenging environments allows for better definition of future workflow requirements, algorithm enhancements, and knowledge integration. These are needed to achieve a geologically reasonable modelling standard and gain insight for poorly constrained geological settings.

description: The task of determining labels of all network nodes based on the knowledge about network structure and labels of some training subset of nodes is called the within-network classification. It may happen that none of the labels of the nodes is known and additionally there is no information about number of classes to which nodes can be assigned. In such a case a subset of nodes has to be selected for initial label acquisition. The question that arises is: "labels of which nodes should be collected and used for learning in order to provide the best classification accuracy for the whole network?". Active learning and inference is a practical framework to study this problem. A set of methods for active learning and inference for within network classification is proposed and validated. The utility score calculation for each node based on network structure is the first step in the process. The scores enable to rank the nodes. Based on the ranking, a set of nodes, for which the labels are acquired, is selected (e.g. by taking top or bottom N from the ranking). The new measure-neighbour methods proposed in the paper suggest not obtaining labels of nodes from the ranking but rather acquiring labels of their neighbours. The paper examines 29 distinct formulations of utility score and selection methods reporting their impact on the results of two collective classification algorithms: Iterative Classification Algorithm and Loopy Belief Propagation. We advocate that the accuracy of presented methods depends on the structural properties of the examined network. We claim that measure-neighbour methods will work better than the regular methods for networks with higher clustering coefficient and worse than regular methods for networks with low clustering coefficient. According to our hypothesis, based on clustering coefficient we are able to recommend appropriate active learning and inference method.

description: Mankind is setting to colonize space, for which the manufacturing of habitats, tools, spare parts and other infrastructure is required. Commercial manufacturing processes are already well engineered under standard conditions on Earth, which means under Earth’s gravity and atmosphere. Based on the literature review, additive manufacturing under lunar and other space gravitational conditions have only been researched to a very limited extent. Especially, additive manufacturing offers many advantages, as it can produce complex structures while saving resources. The materials used do not have to be taken along on the mission, they can even be mined and processed on-site. The Einstein-Elevator offers a unique test environment for experiments under different gravitational conditions. Laser experiments on selectively melting regolith simulant are successfully conducted under lunar gravity and microgravity. The created samples are characterized in terms of their geometry, mass and porosity. These experiments are the first additive manufacturing tests under lunar gravity worldwide.

description: This thesis examines the role of structural violence in the contemporary transition to adulthood of street involved youth. Anchored in structural social work, the study understands the origin of social problems and of violence to be structural rather than individual. Conducted in two phases, the study used participatory action and arts-informed methods, group discussions, and semi-structured interviews. Autonomy, a key component of the contemporary transition to adulthood, was central to the research results. The findings demonstrated that structural violence works to misrepresent or to nullify street involved youths’ expressions of autonomy. Structural violence affects how they exercise and manifest their autonomy as well as how their autonomy is represented or socially valued. The findings made visible the invisible structural violence, illuminating social causes of individual problems. Accordingly, to better support street involved youth and the development of their autonomy during their transition to adulthood, the study proposes recommendations for practice, policy, and research that target systems level change.

description: A survey of some results in the modern microscopic theory of properties of nuclear reactions with gamma-rays is given. First of all, we discuss the impact of phonon coupling (PC) on the photon strength function (PSF) because it represents the most natural physical source of additional strength found for Sn isotopes in recent experiments that could not be explained within the stan- dard HFB+QRPA approach. The self-consistent version of the Extended Theory of Finite Fermi Systems in the Quasiparticle Time Blocking Approximation, or simply QTBA, is applied. It uses the HFB mean field and includes both the QRPA and PC effects on the basis of the SLy4 Skyrme force. With our microscopic E1 PSFs, the following properties have been calculated for many stable and unstable even-even semi-magic Sn and Ni isotopes as well as for double-magic 132Sn and 208Pb using the reaction codes EMPIRE and TALYS with several nuclear level density (NLD) models: 1) the neutron capture cross sections, 2) the corresponding neutron capture gamma spectra, 3) the av- erage radiative widths of neutron resonances. In all the properties considered, the PC contribution turned out to be significant, as compared with the standard QRPA one, and necessary to explain the available experimental data. The results with the phenomenological so-called generalized super- fluid NLD model turned out to be worse, on the whole, than those obtained with the microscopic HFB+combinatorial NLD model. Finally, we also discuss the modern microscopic NLD models based on the self-consistent HFB method and show their relevance to explain experimental data as compared with the phenomeno- logical models. The use of these self-consistent microscopic approaches is of particular relevance for nuclear astrophysics, but also for the study of double-magic nuclei.

description: Beach nourishments are a widely used method to mitigate erosion along sandy shorelines. In contrast to hard coastal protection structures, nourishments are considered as soft engineering, although little is known about the cumulative, long-term environmental effects of both marine sediment extraction and nourishment activities. Recent endeavours to sustain the marine ecosystem and research results on the environmental impact of sediment extraction and nourishment activities are driving the need for a comprehensive up-to-date review of beach nourishment practice, and to evaluate the physical and ecological sustainability of these activities. While existing reviews of nourishment practice have focused on the general design (motivation, techniques and methods, international overview of sites and volumes) as well as legal and financial aspects, this study reviews and compares not only nourishment practice but also the accompanying assessment and monitoring of environmental impacts in a number of developed countries around the world. For the study, we reviewed 205 openly-accessible coastal management strategies, legal texts, guidelines, EIA documents, websites, project reports, press releases and research publications about beach nourishments in several developed countries around the world (Germany, Denmark, the Netherlands, Belgium, Spain, UK, USA and Australia). Where information was not openly available, the responsible authorities were contacted directly. The study elaborates on the differences in coastal management strategies and legislation as well as the large dissimilarities in the EIA procedure (where applicable) for both marine sediment extraction and nourishment activities. The spatial disturbance of the marine environment that is considered a significant impact, a factor which determines the need for an Environmental Impact Assessment, varies substantially between the countries covered in this study. Combined with the large uncertainties of the long-term ecological and geomorphological impacts, these results underline the need to reconsider the sustainability of nourishments as “soft” coastal protection measures.

description: After spending nearly ten years working on the project Immediate Family (1984-91), Southern photographer Sally Mann (b. 1951) turned her camera to the surrounding lush, bucolic and ephemeral Virginia landscape, in a subtle transition she describes as the children slowly slipping from the frame, the landscape coming into primary focus. Using her large-format vintage camera with damaged lenses, sometimes installed in reverse, Mann employed the nineteenth-century wet collodion technique to create atmospheric and haunting images of the Virginia, Georgia and Mississippi landscapes in two sequential bodies of work entitled Mother Land (1996) and Deep South (1998). Mann’s landscapes examine the uneasy confluence of past and present, history and memory, life and death. Through close looking at one image, Untitled (Mississippi Landscape), this paper explores the intersection of personal and public memory and investigates how photographs have the particular power to function as memorial images.

description: The central promise of nanoparticle-based materials is that cooperative properties may emerge, when individual quantum dots are positioned on a periodic lattice. Yet, there are only a few papers in the literature reporting such effects. Nevertheless, it is clear that the symmetry of the superlattice is decisive for the desired emergent phenomena. An interesting question is, how the symmetry of the initial monodisperse nanoparticles affects the structure of the colloidal crystal during self-assembly processes. For instance, particles with a hexagonal cross-section demonstrate self-organization, which is very similar to spherical colloids. Likewise, one would also expect that trigonal nanoparticles behave similarly. Unfortunately, it is very hard to obtain monodisperse semiconductor colloids with a trigonal shape, because this requires a symmetry break during morphogenesis of the nanocrystal. While such a symmetry break is known in the literature for structures attached to a solid substrate, herein, colloidal synthesis of trigonal ZnO nanorods is successfully demonstrated, and the mechanism is elucidated via experimental and theoretical methods. 2D-superlattices formed by such particles with trigonal cross-section are compared to hexagonal analogues. It is found that there are distinct differences, which result in important differences in properties such as the formation of voids and also in optical properties.
Residual stresses in the porcelain veneer layer of all-ceramic restorations
Creators: name: Suranyi, Thomas P.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Objectives: Literature evidence suggests that chipping of the porcelain veneer layer in zirconia based all-ceramic restorations is greater when compared to porcelain fused to metal restorations. The aims of this study were to determine, in vitro, what roles rapid cooling and thermal diffusivity had on chipping and to determine whether failure mechanisms in vitro were comparable to those found in vivo. Methods & Materials: CAD/CAM was used for sample fabrication, with subsequent static and dynamic loading. Specimens were fractographically evaluated. Results: Quantitative analysis revealed higher residual stress in rapidly cooled samples. Fractographic analysis of in vitro samples demonstrated origins of failure and directions of crack propagation stemming from sites adjacent to load application. Conclusion: Samples rapidly cooled were found to have had larger chipping of the veneer layer. The findings of this study demonstrate inconsistent failure mechanisms between laboratory samples and published reports of failure mechanisms found in situ.
Quality failures in Energy-saving renovation projects in Northern China
Creators: name: Qi, Yuting

description: The energy-saving renovation of an existing building is a critical strategy in achieving a longterm energy goal in the Chinese context. However, in China, building energy renovation projects are subjected to quality failures resulting in energy wastage, a decrease in the energy efficiency of the project, an increase in project cost, and thus negatively affecting the overall performance of the renovation projects. In order to avoid them happening in the future, it is essential to find and analyse the causes of quality failures in energy-saving renovation projects. Therefore, using a four-step process, this research aims to deepen the understanding of the causes of quality failures in energy-saving renovation projects of the existing residential buildings. The first and second steps are to identify and analyse the quality failures and their causes. The deeper insights from a quality management perspective are explored in the third step. The fourth step is to investigate how the actors and their interactions affect and cause quality failures during the renovation policy implementation process. This research mainly concludes the causes of quality failures in the building energy renovation projects. It is important to state that most of the quality failures can be avoided at the management level. Some external causes originated at a policy level and outside the project. The findings of this research would be valuable for policy-makers and project coordinators both for predicting and avoiding quality failures and for developing proper action and policy interventions to ensure successful building energy renovations in the future.

Two Late Pleistocene alluvial fan generations, unit K and unit F, were correlated based on surficial weathering and desert pavement characteristics. Cosmogenic 10Be dating of these units yields ages of 38 ± 4 ka and 240 ± 40 ka, respectively (1σ uncertainty). A set of K alluvial fans are offset 30 ± 5 meters along the fault, yielding a slip rate of 0.8 ± 0.2 mm/yr (2σ uncertainty). Total dextral offset of the Lenwood fault is determined to be 1.0 ± 0.2 km based on displacement of the Lenwood anticline. At its present rate of slip, the Lenwood fault may have initiated as recently as ~1 Ma. The results of this study combined with other fault slip rates in the central Mojave Desert reveal a pattern of heterogeneous, slow strain accumulation across the ECSZ.

description: Standard methods in computer model calibration treat the calibration parameters as constant throughout the domain of control inputs. In many applications, systematic variation may cause the best values for the calibration parameters to change between different settings. When not accounted for in the code, this variation can make the computer model inadequate. In this article, we propose a framework for modeling the calibration parameters as functions of the control inputs to account for a computer model's incomplete system representation in this regard while simultaneously allowing for possible constraints imposed by prior expert opinion. We demonstrate how inappropriate modeling assumptions can mislead a researcher into thinking a calibrated model is in need of an empirical discrepancy term when it is only needed to allow for a functional dependence of the calibration parameters on the inputs. We apply our approach to plastic deformation of a visco-plastic self-consistent material in which the critical resolved shear stress is known to vary with temperature.

description: The increasing resolution of three-dimensional (3D) printing offers simplified access to, and development of, microfluidic devices with complex 3D structures. Therefore, this technology is increasingly used for rapid prototyping in laboratories and industry. Microfluidic free flow electrophoresis (μFFE) is a versatile tool to separate and concentrate different samples (such as DNA, proteins, and cells) to different outlets in a time range measured in mere tens of seconds and offers great potential for use in downstream processing, for example. However, the production of μFFE devices is usually rather elaborate. Many designs are based on chemical pretreatment or manual alignment for the setup. Especially for the separation chamber of a μFFE device, this is a crucial step which should be automatized. We have developed a smart 3D design of a μFFE to pave the way for a simpler production. This study presents (1) a robust and reproducible way to build up critical parts of a μFFE device based on high-resolution MultiJet 3D printing; (2) a simplified insertion of commercial polycarbonate membranes to segregate separation and electrode chambers; and (3) integrated, 3D-printed wells that enable a defined sample fractionation (chip-to-world interface). In proof of concept experiments both a mixture of fluorescence dyes and a mixture of amino acids were successfully separated in our 3D-printed μFFE device.

Américanité and Québécité: The Converging Form of Québec Identity as Illustrated in Une histoire américaine and Le déclin de l'empire américain
Creators: name: Beck, Megan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: This paper explores the presentations of identity as they relate to the post-referendum Québec society of the 1980s. Specifically, it uses Jacques Godbout’s novel Une histoire américaine and Denys Arcand’s film, Le déclin de l’empire américain, to underscore the relationship of Québec to North America, and the cultural and geographical influences of the province and the United States in particular. Using américanité as a filter, the two works provide images of québécois society that reflect the province-wide sentiment following the failed nationalist agenda. This paper efforts to relate the competing notions of américanité and québécité through the social constructions of marriage, family, love and relationships as well as the crisis of identity of individual characters, all of which inform the overall presentations of what it meant to be a citizen of Québec in the post-referendum society.
An Investigation of the Relationship Between Junior Girl's Golf Ratings and NCAA Division I Women's Golf Ratings
Creators: name: Earley, Patricia Lyn
Publisher: name: University of North Carolina at Chapel Hill
Year: 2011

description: Coaches often depend on rating systems to determine who to recruit. But how reliable are these ratings? Do they help coaches find a player that will contribute to the team's success? This research examined the degree of importance that should be placed on junior golf ratings and if these ratings will help college coaches predict the impact of each recruit. The research sought to discover the relationship between 207 subjects' junior golf ratings(Golfweek/Sagarin Junior Girls Golf Ratings) and their freshman, sophomore, junior and senior year golf ratings(NCAA Division I Women's College Golf Ratings), rate of improvement and number of starter years using simple regression. A significant relationship was found between junior golf ratings and the freshman, sophomore, junior and senior year NCAA Division I women's college golf ratings. A significant relationship was found between junior golf ratings and starter years but not with the rate of improvement.

description: Many methods have been proposed for community detection in networks, but most of them do not take into account additional information on the nodes that is often available in practice. In this paper, we propose a new joint community detection criterion that uses both the network edge information and the node features to detect community structures. One advantage our method has over existing joint detection approaches is the flexibility of learning the impact of different features which may differ across communities. Another advantage is the flexibility of choosing the amount of influence the feature information has on communities. The method is asymptotically consistent under the block model with additional assumptions on the feature distributions, and performs well on simulated and real networks.

description: The different reactivity of trienones under Lewis and Brønsted acids catalysis was investigated, resulting in distinct cyclization products and carbon backbones that originated either from a conjugate Prins cyclization or an interrupted Nazarov cyclization. In particular, an unprecedented Nazarov cyclization tandem reaction is presented, terminating the oxyallyl cation by an ene-type reaction, and leading stereoselectively to bicyclic spiro compounds. The terminal olefin of this motif represents a useful handle for further functionalization, making it a strategic intermediate in total syntheses. The tandem Nazarov/ene cyclization was shown to be preferred over a Nazarov/[3+2] tandem reaction for all our substrates, independent of chain length. Deuteration studies further support the mechanistic hypothesis of the terminating ene reaction.

description: Many physical implementations of qubits---including ion traps, optical lattices and linear optics---suffer from loss. A nonzero probability of irretrievably losing a qubit can be a substantial obstacle to fault-tolerant methods of processing quantum information, requiring new techniques to safeguard against loss that introduce an additional overhead that depends upon the loss rate. Here we present a scalable and platform-independent protocol for estimating the average loss rate (averaged over all input states) resulting from an arbitrary Markovian noise process, as well as an independent estimate of detector efficiency. Moreover, we show that our protocol gives an additional constraint on estimated parameters from randomized benchmarking that improves the reliability of the estimated error rate and provides a new indicator for non-Markovian signatures in the experimental data. We also derive a bound for the state-dependent loss rate in terms of the average loss rate.

Rivalry and desire: male-male relations in Ovid's Amores and French feminist theory
Creators: name: Bunner, Emily Dawn
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: This thesis examines the role of male-male rivalry within Ovid's Amores by using French feminist theory to interpret how the exchange of women, among men, characterizes the amator's relations to the puella, his rivals, and his poetry. The amator's focus on the actions and attitudes of his rivals reveals the mediating function of the puella, who is valued for her ability to create relations between men and to allow men to maintain these relations through contact with her body. This rivalry is also important at the metatextual level: just as the amator desires the puella because she has been made valuable by the desire of other men, the themes he borrows from epic poetry are valuable because they belong to and are valued by other authors. Both the puella and text are the product of male desire that is structured by the amator's interaction with his rivals.
