Development And Use Of A Model To Predict Properties Of Infiltrated Solid Oxide Fuel Cell Anodes

Solid oxide fuel cells (SOFCs) provide a potentially clean way of using energy sources. One important aspect of a functioning fuel cell is the anode and its characteristics (e.g. conductivity). Using infiltration of conductor particles has been shown to be a method for production at lower cost with comparable functionality. While these methods have been demonstrated experimentally, there is a vast range of variables to consider. Because of the long time for manufacture, a model is desired to aid in the development of the desired anode formulation. This thesis aims to (1) use an idealized system to determine the appropriate size and aspect ratio to determine the percolation threshold and effective conductivity as well as to (2) simulate the infiltrated fabrication method to determine the effective conductivity and percolation threshold as a function of ceramic and pore former particle size, particle fraction and the cell¿s final porosity. The idealized system found that the aspect ratio of the cell does not affect the cells functionality and that an aspect ratio of 1 is the most efficient computationally to use. Additionally, at cell sizes greater than 50x50, the conductivity asymptotes to a constant value. Through the infiltrated model simulations, it was found that by increasing the size of the ceramic (YSZ) and pore former particles, the percolation threshold can be decreased and the effective conductivity at low loadings can be increased. Furthermore, by decreasing the porosity of the cell, the percolation threshold and effective conductivity at low loadings can also be increased

Solar Photovoltaic Energy Project Development on Brownfields: Leveraging Policy Incentives and Project Financing Mechanisms

This study evaluates the practice of redeveloping Brownfields with solar photovoltaic renewable energy technology. Utilizing renewable energy as a strategy to reuse contaminated or potentially contaminated property is a relatively new convention. While the benefits of redeveloping Brownfields are well established, ongoing challenges and limited literature on the subject complicate the practice. Challenges, opportunities, and benefits related to renewable energy development on Brownfields are identified and analyzed. Strategic leveraging of federal, state, local, and utility incentives for renewable energy and Brownfield revitalization, and gap finance tools is explored and evaluated. A comparison of three photovoltaic Brownfield projects is analyzed for critical success and failure factors, and lessons learned. A recommendation of best practices is made based on findings and results.

Collaborative resource development for energy efficiency education

BACKGROUND There is a growing volume of open source ‘education material’ on energy efficiency now available however the Australian government has identified a need to increase the use of such materials in undergraduate engineering education. Furthermore, there is a reported need to rapidly equip engineering graduates with the capabilities in conducting energy efficiency assessments, to improve energy performance across major sectors of the economy. In January 2013, building on several years of preparatory action-research initiatives, the former Department of Industry, Innovation, Climate Change, Science, Research and Tertiary Education (DIICCSRTE) offered $600,000 to develop resources for energy efficiency related graduate attributes, targeting Engineers Australia college disciplines, accreditation requirements and opportunities to address such requirements. PURPOSE This paper discusses a $430,000 successful bid by a university consortium led by QUT and including RMIT, UA, UOW, and VU, to design and pilot several innovative, targeted open-source resources for curriculum renewal related to energy efficiency assessments, in Australian engineering programs (2013-2014), including ‘flat-pack’, ‘media-bites’, ‘virtual reality’ and ‘deep dive’ case study initiatives. DESIGN/ METHOD The paper draws on literature review and lessons learned by the consortium partners in resource development over the last several years to discuss methods for selecting key graduate attributes and providing targeted resources, supporting materials, and innovative delivery options to assist universities deliver knowledge and skills to develop such attributes. This includes strategic industry and key stakeholders engagement. The paper also discusses processes for piloting, validating, peer reviewing, and refining these resources using a rigorous and repeatable approach to engaging with academic and industry colleagues. RESULTS The paper provides an example of innovation in resource development through an engagement strategy that takes advantage of existing networks, initiatives, and funding arrangements, while informing program accreditation requirements, to produce a cost-effective plan for rapid integration of energy efficiency within education. By the conference, stakeholder workshops will be complete. Resources will be in the process of being drafted, building on findings from the stakeholder engagement workshops. Reporting on this project “in progress” provides a significant opportunity to share lessons learned and take on board feedback and input. CONCLUSIONS This paper provides a useful reference document for others considering significant resource development in a consortium approach, summarising benefits and challenges. The paper also provides a basis for documenting the second half of the project, which comprises piloting resources and producing a ‘good practice guide’ for energy efficiency related curriculum renewal.

Supporting the development and deployment of sustainable energy technologies through targeted scientific training

Sustainable energy technologies rely heavily on advanced materials and modern engineering controls. These promising new technologies cannot be reliably deployed without ensuring that there is a sufficient “capacity,” i.e., trained technical personnel with the expertise to implement, monitor, and maintain the energy infrastructure. This same capacity is critical to the local development of new technologies, especially those that respond directly to regional priorities, strengths, and needs. One way to build capacity is through targeted programs that integrate the training and development of locals at an advanced technical level. In practical terms, these programs usually produce a small number of highly educated individuals with skills in science and engineering. The goal of Part VI of this book is to highlight contributing factors in successfully operating capacity building programs.

The Presence of Multiple Cellular Defects Associated with a Novel G50E Iron-Sulfur Cluster Scaffold Protein ( ISCU) Mutation Leads to Development of Mitochondrial Myopathy

Background: Muscle-specific deficiency of iron-sulfur (Fe-S) cluster scaffold protein (ISCU) leads to myopathy. Results: Cells carrying the myopathy-associated G50E ISCU mutation demonstrate impaired Fe-S cluster biogenesis and mitochondrial dysfunction. Conclusion: Reduced mitochondrial respiration as a result of diminished Fe-S cluster synthesis results in muscle weakness in myopathy patients. Significance: The molecular mechanism behind disease progression should provide invaluable information to combat ISCU myopathy. Iron-sulfur (Fe-S) clusters are versatile cofactors involved in regulating multiple physiological activities, including energy generation through cellular respiration. Initially, the Fe-S clusters are assembled on a conserved scaffold protein, iron-sulfur cluster scaffold protein (ISCU), in coordination with iron and sulfur donor proteins in human mitochondria. Loss of ISCU function leads to myopathy, characterized by muscle wasting and cardiac hypertrophy. In addition to the homozygous ISCU mutation (g.7044GC), compound heterozygous patients with severe myopathy have been identified to carry the c.149GA missense mutation converting the glycine 50 residue to glutamate. However, the physiological defects and molecular mechanism associated with G50E mutation have not been elucidated. In this report, we uncover mechanistic insights concerning how the G50E ISCU mutation in humans leads to the development of severe ISCU myopathy, using a human cell line and yeast as the model systems. The biochemical results highlight that the G50E mutation results in compromised interaction with the sulfur donor NFS1 and the J-protein HSCB, thus impairing the rate of Fe-S cluster synthesis. As a result, electron transport chain complexes show significant reduction in their redox properties, leading to loss of cellular respiration. Furthermore, the G50E mutant mitochondria display enhancement in iron level and reactive oxygen species, thereby causing oxidative stress leading to impairment in the mitochondrial functions. Thus, our findings provide compelling evidence that the respiration defect due to impaired biogenesis of Fe-S clusters in myopathy patients leads to manifestation of complex clinical symptoms.

A biogeographic asssessment of seabirds, deep sea corals and ocean habitats of the New York Bight: science to support offshore spatial planning

This report provides a compilation of new maps and spatial assessments for seabirds, bathymetry, surficial sediments, deep sea corals, and oceanographic habitats in support of offshore spatial planning led by the New York Department of State Ocean and Great Lakes Program. These diverse ecological themes represent priority information gaps left by past assessments and were requested by New York to better understand and balance ocean uses and environmental conservation in the Atlantic. The main goal of this report is to translate raw ecological, geomorphological and oceanographic data into maps and assessments that can be easily used and understood by coastal managers involved in offshore spatial planning. New York plans to integrate information in this report with other ecological, geophysical and human use data to obtain a broad perspective on the ocean environment, human uses and their interactions. New York will then use this information in an ecosystem-based framework to coordinate and support decisions balancing competing demands in their offshore environment, and ultimately develop a series of amendments to New York’s federally approved Coastal Management Program. The targeted users of this report and the compiled spatial information are New York coastal managers, but other State and federal decision-makers, offshore renewable energy development interests and environmental advocates will also find the information useful. In addition, the data and approaches will be useful to regional spatial planning initiatives set up by the Mid-Atlantic Regional Council on the Ocean (MARCO) and federal regional planning bodies for coastal and marine spatial planning.

REDUCING DIESEL DEPENDENCE IN NUNAVUT: INTEGRATING RENEWABLE ENERGY TECHNOLOGIES THROUGH POLICY ACTIONS

In the last fifty years, Nunavut has developed a deep dependence on diesel for virtually all of its energy needs, including electricity. This dependence has created a number of economic, environmental and health related challenges in the territory, with an estimated 20% of the territory’s annual budget being spent on energy, thereby limiting the Government of Nunavut’s ability to address other essential infrastructure and societal needs, such as education, nutrition and health care and housing. One solution to address this diesel dependency is the use of renewable energy technologies (RETs), such as wind, solar and hydropower. As such, this thesis explores energy alternatives in Nunavut, and through RETScreen renewable energy simulations, found that solar power and wind power are technically viable options for Nunavut communities and a potentially successful means to offset diesel-generated electricity in Nunavut. However, through this analysis it was also discovered that accurate data or renewable resources are often unavailable for most Nunavut communities. Moreover, through qualitative open-ended interviews, the perspectives of Nunavut residents with regards to developing RETs in Nunavut were explored, and it was found that respondents generally supported the use of renewable energy in their communities, while acknowledging that there still remains a knowledge gap among residents regarding renewable energy, stemming from a lack of communication between the communities, government and the utility company. In addition, the perceived challenges, opportunities and gaps that exist with regards to renewable energy policy and program development were discussed with government policy-makers through further interviews, and it was discovered that often government departments work largely independently of each other rather than collaboratively, creating gaps and oversights in renewable energy policy in Nunavut. Combined, the results of this thesis were used to develop a number of recommended policy actions that could be undertaken by the territorial and federal government to support a shift towards renewable energy in order to develop a sustainable and self-sufficient energy plan in Nunavut. They include: gathering accurate renewable resource data in Nunavut; increasing community consultations on the subject of renewable energy; building strong partnerships with universities, colleges and industry; developing a knowledge sharing network; and finally increasing accessibility to renewable energy programs and policies in Nunavut.

Digital Methods for Process Development in Manufacturing and Their Relevance to Value Driven Design

This paper examines the applicability of a digital manufacturing framework to the implementation of a Value Driven Design (VDD) approach for the development of a stiffened composite panel. It presents a means by which environmental considerations can be integrated with conventional product and process design drivers within a customized, digital environment. A composite forming process is used as an exemplar for the work which creates a collaborative environment for the integration of more traditional design drivers with parameters related to manufacturability as well as more sustainable processes and products. The environmental stakeholder is introduced to the VDD process through a customized product/process/resource (PPR) environment where application specific power consumption and material waste data has been measured and characterised in the process design interface. This allows the manufacturing planner to consider power consumption as a concurrent design driver and the inclusion of energy as a parameter in a VDD approach to the development of efficiently manufactured, sustainable transport systems.

Energy Management in UK Non-Domestic Buildings - a New Perspective to Provoke Reduced Carbon Emissions

Politicians, industry and the public generally accept the need for energy consumption to be cut to deliver climate change mitigation measures essential for us to avoid climate disaster. For non-domestic fuel users current energy policy has attempted to drive this through rational economic responses to energy cost pressures. This reliance on voluntary action has created an “Energy Inconsistency”, that is a marked difference between energy opportunities that have been proven technically viable, financially rational and retrofit feasible and those actually adopted. Other factors must therefore be involved to influence what appear to be simple carbon and cost saving opportunities. This paper presents a new approach to energy efficiency and consumption in non-domestic buildings, viewing attitudes and behaviours of building owners and users as the key driver of energy consumption. A new framework is proposed as a method to examine the impact of building ownership on the users’ and owners’ abilities to improve energy efficiency and consumption and identify opportunities to overcome the barriers inherent in these ownership structures.

Federal-provincial relations and the environment : attaining sustainable development through cooperation /

A study of intergovernmental relations in the area of the environment will determine whether the current Canadian federal structure represents a dangerous impediment to the promotion of sustainable development. This paper examines the interjurisdictional quagmire that has developed from the fact that authority over the environment is a functionally concurrent field for the two orders of government. A history of federal-provincial relations in the area of environmental protection is followed by an analysis of the advantages and disadvantages associated with competitive and cooperative federalism. For the purpose of this paper, cooperative federalism is characterized by the presence of a formal institutional system to facilitate interaction between politicians and bureaucrats from both orders of government. Competitive federalism is defined as a system that lacks a formal institutional structure to promote discussion and coordination between federal and provincial officials in a specific field of interest. Last, I examine thirty sustainable development issues following the structure established in Agenda 21 to determine the impact of the present federal system on the development of these objectives. This study concludes that Canadian federalism is not a dangerous impediment to the promotion of sustainable development. Cooperative federalism in a form that does not eliminate the ability of governments to revert to competition promotes the emergence of an institutional system that facilitates information-sharing and discussion between the two orders of government, thus leading to coordinated efforts in the field of the environment. Respect for the current division of powers in this area is also essential to the cohesiveness of Canadian society. Policy-makers and advocates for a sustainable society should focus on working within the present system.

Development of a methodology to investigate the importance of chemical speciation on the bioavailability of contaminants to Eisenia andrei

The uptake of metals by earthworms occurs predominantly via the soil pore water, or via an uptake route which is related to the soil pore water metal concentration. However, it has been suggested that the speciation of the metal is also important. A novel technique is described which exposes Eisenia andrei Bouche to contaminant bearing solutions in which the chemical factors affecting its speciation may be individually and systematically manipulated. In a preliminary experiment, the LC50 for copper nitrate was 0.046 mg l(-1) (95 % confidence intervals: 0.03 and 0.07 mg l(-1)). There was a significant positive correlation between earthworm mortality and bulk copper concentration in solution (R-2 = 0.88, P less than or equal to 0.001), and a significant positive increase in earthworm tissue copper concentration with increasing copper concentration in solution (R-2 = 0.97, P less than or equal to 0.001). It is anticipated that quantifying the effect of soil solution chemical speciation on copper bioavailability will provide an excellent aid to understanding the importance of chemical composition and the speciation of metals, in the calculation of toxicological parameters.

A Comissão Executiva do Plano da Lavoura Cacaueira (CEPLAC): um caso de desenvolvimento institucional

Esta monografia é um estudo de desenvolvimento institucional que proporciona conhecer como uma organização da administração pública brasileira, criada com um fim especifico e transitório, sobreviveu, se transformou, criou raizes, expandiu sua área de influência e tornou-se uma instituição relativamente bem sucedida. Trata-se da Comissão Executiva do Plano da Lavoura Cacaueira - CEPLAC, órgão autônomo vinculado ao Ministério da Agricultura, criado na década de cinqüenta pelo Governo Federal, como solução de emergência para o apoio financeiro aos produtores de cacau do sul da Bahia, numa das maiores crises da economia cacaueira. O autor valeu-se, para sua dissertação, do quadro conceitual formulado por Milton J. Esman e Hans C. Blaise, da Inter-University Research Program in Institution Building. Este é um modelo que parte da premissa de que as instituições são sistema abertos e, como tal, mantêm padrões de relações e intercâmbio com o meio-ambiente em que operam. Importam energia do ambiente (inputs on entradas) e processam tais energias, transformando-as em produtos (outputs ou saldas) desejados e valorizados pelo ambiente. Dentro deste quadro, têm-se três elementos básicos: a organização; as transações; e o meio-ambiente. O trabalho foi dividido em cinco capítulos. No primeiro o autor discorreu sobre o tema e sua importância, objetivos do estudo, metodologia utilizada e o conteúdo da monografia. No segundo, fez uma discussão em torno do que é desenvolvimento institucional, sua evolução como estratégia de desenvolvimento; procedeu à revisão de literatura e descreveu o modelo que serviu de guia à pesquisa. Aí, registrou disfunções, limitações e restrições ao modelo de Esman e Blaise, e/ou aos efeitos da institucionalização, apontados por alguns estudiosos. No terceiro capítulo narrou os antecedentes, origem e evolução da CEPLAC, oportunidade em que identificou três fases da organização; no quarto, mostrou a CEPLAC através do modelo de desenvolvimento institucional, quando a organização foi analisada em função de suas variáveis institucionais (Liderança, Doutrina, Programa, Estrutura I nterna e Recursos), suas t ra n sações com o ambiente e suas variáveis institucionais-ambientais ou simplesmente elos institucionais. Finalmente, no qu into cap(tulo, alinhou as conclusões. A pesquisa objetivou atender aos questionamentos estabelecidos em cinco tópicos que buscavam investigar o seguinte: se houve um planejamento prévio, consciente e deliberado no sentido de transformar a CEPLAC de um órgão transitório, com atividade financeira, para uma instituição técnico-cientl'fica como é hoje. Em caso negativo, o que tornou isso poss(vel? Discorrer sobre a forma pela qual seu quadro dirigente foi estruturado e reuniu recursos, bem como que influências contribuíram para moldar seus programas; constatar como o quadro dirigente da CEPLAC manteve-se estável em um per(odo de mudanças no panorama político brasileiro; e especular sobre o futuro da institu ição. Entre outras coisas, o autor conclu iu que duas variáveis contribu iram particu larmente, de forma decisiva, para a sobrevivência, autonomia e desenvolvimento da instituição, com a obtenção de resultados valorizados pela sua clientela: 1) a existência de uma liderança institucional que soube definir o papel e a missão da CEPLAC, mantendo sua integridade ao longo do tempo; e, 2) a garantia de um fluxo sistemático de recursos financeiros através da contribuição cambial retirada das exportações de cacau. Além disso, constatou que três fatores foram importantes para sua estabilidade: o pleno enquadramento da instituição na filosofia modernizadora contida no bojo dos governos pós-54; a relevância de seus elos institucionais; e o reconhecimento da cl ientela e de setores governamentais importantes pela sua participação na evolução havida na economia cacaueira, de uma situação de crise para resultados satisfatórios.
