This master´s thesis deals with the experimental analysis of the coefficient of friction and lubrication film in total knee replacement. The experiments are performed on a knee joint simulator, with an implemented module for measuring friction. To observe film formation, fluorescent microscopy is used. The experiments are mainly focused on a detailed description of the influence of parameters occurring during the gait cycle. This approach should significantly help in describing the tribological processes that occur in the total knee replacement. The results confirm previous investigations in terms of axial load, where the coefficient of friction decreases with the increasing load. In the case of lubrication film, no significant changes are observed. On the contrary, while investigating the influence of SRR, noticeable changes in film formation are observed while the coefficient of friction being unaffected. While describing the whole gait cycle, precise results are obtained only in the first half of the cycle as the second half is accompanied by the occurrence of large deviations from a rapid decrease of load. This work provides a better understanding of the field of lubrication film in total knee replacements. Moreover, thanks to the simultaneous measurement of the coefficient of friction and the observation of the contact area, it is possible to draw better conclusions than if the experiments had been carried out separately.

Stationary electrical connections and contacts, such as power connections, are commonly applied in electric power systems used for generation, transmission and distribution of electric energy. Several different degradation mechanisms can increase the contact resistance and might therefore reduce the power connection’s lifetime. The degradation by film development as a result of chemical reactions is often considered as a reason for contact failure. In this research work, the impact of film development produced by chemical reactions, such as oxidation, on the long-term behavior of stationary electrical connections and contacts was studied with crossed rods. Analytical, numerical and experimental methods were applied. Typical material systems for electric power systems were considered in this study: Cu-ETP (CW004A) bare, silver-, nickel- or tin-coated, Al99.5 (EN AW-1050A) and AlMgSi0.5 (EN AW-6060). By applying numerical methods, the mechanical stress distribution was determined within a circular contact point. The initial contact resistance and the plastic deformed area of the considered material systems was measured in experimental tests. The film’s impact was further determined through comparative experimental studies in air (standard atmosphere) and N2 (inert gas). During the experimental tests on perpendicularly crossed rods, other degradation mechanisms such as force reduction were suppressed. The film’s impact within the formation phase was studied on copper rods in an oven at 200 °C for 1000 h. Moreover, the dependency on different environments at 90 °C (laboratory, botanical garden and outdoor) was tested for 12000 h. Additional long-term tests over 12000 h were conducted at 200 °C. The contact resistance was determined dependent on time. Furthermore, the plastic deformed area was ascertained by microscopy. It was found that the time dependent film development caused by chemical reactions such as oxidation might possibly not result in a significant degradation of stationary electrical contacts with circular contact points and a constant force. Supplementary studies were performed at 200 °C for 1000 h with perpendicularly crossed rods at low forces (3.5 N) as well as analytical assessment of radial and axial film growth on circular contact points. The measured long-term behavior of perpendicularly crossed rods was similar for low and high forces. In order to study the long-term behavior of power connections operated in areas with harsh environmental conditions, experimental field tests on bolted busbar joints were conducted in desert and tropical rainforest environments. For over two and a half years, long-term field tests investigating bolted busbar joints made of Cu-ETP, Al99.5 (EN-AW-1350A) or AlMgSi0.5 (EN AW-6060) either with or without coating (silver, tin or nickel) were conducted in Belém (Brazil), Ismailia (Egypt) and Dresden (Germany).

This thesis attempts to take seriously the claims made by many postapocalyptic zombie narratives to represent the world as it truly is, analyzing and then assessing the theological value of their depictions of the human predicament. The approach is both formal and what Gary Wolfe calls transmedial, examining the recurring narrative structures and themes of texts across several media and eras as part of 'a popular aesthetic movement and not just a body of works of fiction on similar themes', with special attention given to the films and television of the new millennium. The aim is twofold: to extend the relevance of postapocalyptic zombie fictions beyond the relatively narrow vogue of a cultural moment, and to prompt a richer appreciation of the significance of the Christian faith within contemporary society. To this end, Chapter One contextualizes the complexity of these texts' relationship to Christianity by examining first the most prominent obstacles and then the implicit promise of these texts for theological reflection. It places special emphasis on the interior tension in many of these fictions between, on the one hand, aggressively emphasizing the apparent absence of the supernatural, while on the other, frequently claiming to disclose a dimension of human experience in excess of what can be ordinarily perceived by the senses. Chapters Two and Three extend this analysis to the complex content of what these stories depict. Chapter Two considers the multilayered symbolism of decline in their conspicuous spectacles of disaster, disintegration, and death. Chapter Three examines the countervailing symbolic motifs of residual integrity and regeneration that are exhibited most prominently by characters who attempt to live genuinely human lives in spite of these circumstances. The first half of the thesis concludes by proposing a composite postapocalyptic view of the human predicament, which represents the world as ambiguous, dramatic and quite possibly, although not certainly, absurd. Chapter Four begins the theological reflection upon this kind of postapocalyptic perspective, proposing how such depictions might be illuminated by Christian theological descriptions, particularly the absurd existential circumstances brought about by the original sin. Chapter Five, reciprocally, suggests some of the ways the dramatic images of these texts might enrich theological reflection by eliciting fresh insights into the significance of the central mysteries of Christianity, especially the paradoxical already-and-not-yet of eschatological expectation. The thesis concludes by offering a final evaluation of whether, all told, the world can be truly considered postapocalyptic from a Christian perspective, arguing that although there are significant differences, postapocalyptic fictions and Christianity put forward strikingly similar pictures of the deeply self-conflicted circumstances of the common human predicament.
