The literary-theoretical influences on the thought of Hans Frei and Paul Ricoeur, with reference to narrative identity
No full textThis thesis analyses those differences in interpretation which occur when separate literary-theoretical approaches are applied to biblical texts. Hans
Frei suggests that the biblical texts describe the world in a way which he calls "realistic narrative". Paul Ricoeur's hermeneutic recognises the disclosive power of the text and translates the subject matter of the text into a "way-of-
being-in-the-world". Thus, the primary identity disclosed by the biblical narratives differs. For Frei, it is the identity of Jesus which is disclosed; for Ricoeur, it is "our common human Christian identity". These two thinkers have usually been compared theologically. However, I contend that the theological investigations of both Frei and Ricoeur have been influenced by the literary approaches which guide their theological work. I give an exposition of this relationship in chapter one. In chapter two, I sketch out the implications of this relationship, focusing on the issue of narrative identity. In the final chapter, critiques of both systems are investigated as I attempt to deal with the force of these objections. This dissertation investigates Frei's and Ricoeur's construals of narrative identity (as constructed through the reading of Biblical texts). My working hypothesis is that the construals of identity formulated by Frei and Ricoeur rely upon formalist, narrative "interpretations”. My thesis contends that in their respective approaches to the notion of narrative identity, neither thinker has completely abandoned his early literary-theoretical roots in his theological proposals
Discovery of antibacterial manganese(i) tricarbonyl complexes through combinatorial chemistry
No full text: The continuous rise of antimicrobial resistance is a serious threat to human health and already causing hundreds of thousands of deaths each year. While natural products and synthetic organic small molecules have provided the majority of our current antibiotic arsenal, they are falling short in providing new drugs with novel modes of action able to treat multidrug resistant bacteria. Metal complexes have recently shown promising results as antimicrobial agents, but the number of studied compounds is still vanishingly small, making it difficult to identify promising compound classes or elucidate structure-activity relationships. To accelerate the pace of discovery we have applied a combinatorial chemistry approach to the synthesis of metalloantibiotics. Utilizing robust Schiff-base chemistry and combining 7 picolinaldehydes with 10 aniline derivatives, and 6 axial ligands, either imidazole/pyridine-based or solvent, we have prepared a library of 420 novel manganese tricarbonyl complexes. All compounds were evaluated for their antibacterial properties and 10 lead compounds were identified, re-synthesised and fully characterised. All 10 compounds showed high and broad activity against Gram-positive bacteria. The best manganese complex displayed low toxicity against human cells with a therapeutic index of >100. In initial mode of action studies, we show that it targets the bacterial membrane without inducing pore formation or depolarisation. Instead, it releases its carbon monoxide ligands around the membrane and inhibits the bacterial respiratory chain. This work demonstrates that large numbers of metal complexes can be accessed through combinatorial synthesis and evaluated for their antibacterial potential, allowing for the rapid identification of promising metalloantibiotic lead compounds
IN-SITU PERFORMANCE OF SU-FREI BRIDGE BEARINGS
No full textStable Unbonded Fibre Reinforced Elastomeric Isolators (SU-FREI) have been investigated extensively for seismic applications, with over 20 years of literature supporting their use in isolation of structures as an alternative to conventional Steel Reinforced Elastomeric Isolators (SREI). Preliminary investigations have been conducted into their potential use as bridge bearings, where they could provide an alternative to unreinforced and steel reinforced elastomeric bearings. SU-FREI offer a number of potential advantages in this application relative to SREI, including compactness due to thinner reinforcement layers, ease of installation, rotational tolerances, and ease of manufacture. Recently, SU-FREI have been installed under certain highway bridges along the 407 ETR where the previous unreinforced elastomeric bearings had experienced failure. Monitoring has been conducted by Associated Engineering for the 407 ETR Corporation.
Data was collected from this monitoring program and field visits have been conducted to observe the condition of the bearings. The original design process used for the SU-FREI bearings has also been reviewed. The monitoring data was compared against design calculations, and the behavior of the SU-FREI analysed to determine whether they meet performance expectations and are suitable for further use as bridge bearings.
It was found that some SU-FREI had experienced degradation, including the appearance of an unidentified liquid. The causes of deterioration were investigated and postulated to be primarily related to design limitations imposed by the geometry of the bridges, original design calculation assumptions, and installation issues. Where these factors were not present, the SU-FREI bearings were found to have experienced little to no deterioration. Furthermore, it was determined through comparative design calculations that the FREI outperformed equivalent SREI with regard to rotational capacity.
Recommendations have been developed for future deployment of SU-FREI as bridge bearings. Based on the results of initial deployments, larger-scale employment of SU-FREI in this application should be considered.ThesisMaster of Applied Science (MASc)Concrete and steel bridges deform due to temperature changes, traffic motion, and other factors. To allow these deformations without inducing large forces or damage, bearings are employed between the bridge deck and supports.
One type of bearing consists of alternating layers of rubber and steel: steel strengthens the bearing, while the rubber provides lateral and rotational flexibility. A relatively new type of bearing has been developed and tested that replaces the steel layers with carbon fibre. Recently, several of these new SU-FREI bearings have been installed on actual highway bridges.
The focus of this thesis is on the performance of SU-FREI installed as bridge bearings. The goal was to observe their performance, identify any unexpected behavior, and create recommendations for future consideration whenever SU-FREI are to be used as bridge bearings. Generally, it was found that their performance is satisfactory provided they are designed and used appropriately
Hans Frei: theology and method
No full textA continuación se abordan temas centrales de la teología elaborada por Hans Frei, autor poco conocido en el contexto regional latinoamericano. La presentación se encuentra delimitada a su pensamiento tardío, y muestra su concepción tanto de teología como de método teológico. También busca destacar la transformación de la reflexión de Frei, que vincula progresivamente un creciente interés por aspectos vitales y contextuales de las comunidades creyentes.This article introduces main topics of Hans Frei’s theology. This author is not well known in the Latin American regional context. This presentation is circumscribed to his late thought and it shows Frei’s understanding as much of theology as of theological method. It also seeks to highlight the transformation of Frei´s reflection when he connects this reflection to his growing interests for vital and contextual aspects of the believer communities
A Decision Support System for Planning Eco-Effective Products
No full textProduct planning has been received great interests because of its impacts on major decisions during product design. Planning eco-effective products is the interface among product design, environment, and management, therefore the required information should considers technical, environmental, and economical aspects. To make the decision process more effective, decision support system which facilitates access to relevant information should be process more effective, decision support system which facilitates access to relevant information should be prepared based on the models, databases, and interfaces. Full implementation of such a system provides a road map for life cycle thinking and analytic processes that are nesessary to truly integrate environmental and business strategies
Reverse supply chains
No full textA Circular Economy Handbook for Business and Supply Chains is an easily digestible and comprehensive handbook that provides a clear guide to the circular economy, helping the reader create future-fit, sustainable strategies. Real examples across a range of market sectors help businesses, students and policymakers understand the theory and fast-developing practice of the circular economy. To help the reader generate ideas, A Circular Economy Handbook for Business and Supply Chains provides a holistic framework for the design and supply chain and supporting business models, and includes tools the reader can use to get started.
Whilst growing global consumption presents fantastic business opportunities, our current linear systems (take some materials, make a product, use it and then throw it away) are not fit for purpose. The circular economy unlocks this problem by decoupling resources from consumption. Engaged businesses are re-thinking product design, material choices, business models and supply chains. A Circular Economy Handbook for Business and Supply Chains is a must-read for anyone who wants to apply the circular economy today. Online resources now available: PowerPoint slides of figures and tables from every chapter created by the author
Frei Otto and the development of gridshells
No full textAbstractThe innovative architect, Frei Otto, developed the concept of gridshells which could be designed by a funicular modelling method and constructed from an equal mesh net of timber laths bent into the planned shape. In 1970 this technique was used to construct a 9000m2 curved roof structure from 5cm square timber laths. This paper summarises the design and engineering work that went into the construction of this remarkable building
