Asphalt Rubber Cement Concrete Webster County, HR-555, Final Report, 2003

Discarded tires have become a major disposal problem in the U.S. Different techniques of recycling these discarded tires have been tried. The state of Iowa has evaluated the use of discarded tires ground into crumb rubber and blending it with asphalt to make asphalt rubber cement (ARC). This was the sixth project using this process. The project is located on US 169 from the east junction of IA 175 west and north to US 20. Only the binder course was placed during this research with the surface course to be let at a later date. There were four test sections, two sections with conventional mixtures and two with ARC mixtures. There were no significant differences in placement or performance between the two mix types. The cost of the ARC mixture was significantly higher.

1102-001 Twelve Mile Lake Final Report

Twelve-Mile Lake is an 800-acre man-made lake in central Union County. The watershed has 13,964 land acres that are used by farmers for row crops and pasture. This lake is used as a water supply source for the City of Creston and the Southern Iowa Rural Water Association. In total approximately 40,000 people are affected by this project. Developed over 20 years ago, the lake and fishery was renovated and restocked and much of the shoreline was riprapped about six years ago. During its history, extensive watershed efforts have been ongoing. However, as farmland for cropland has become more valuable and demand has increased, hilly land once used for dairy farming, grazing, and CRP has been put into row crop production. Consequently, sediment loss has become an increasing issue for farmers, conservation professionals, and the Creston Waterworks Department, which owns the water treatment facility at the lake. In 2011, the Creston Water Board received a WIRB grant to implement a sedimentation structure at the north end of the main channel flowing into the lake. The WIRB funds were used for land acquisition, with the IDNR actually constructing the facility. This report depicts work performed as part of the WIRB project.

06027-013 Leisure Lake Watershed Final Report

Leisure Lake is approximately a 67 acre water body located in northwest Jackson County with a 2,681 acre drainage area. The watershed including the lake is a tributary to Lytle Creek which drains into the North Fork of the Maquoketa River. Portions of the Lytle Creek and North Fork Maquoketa River are on the 303(d) impaired waterbodies list. The project area includes a community of 370 residential properties and one business that currently has no central wastewater collection and treatment system. The purpose of this project is to construct a wastewater collection and treatment facility to improve water quality in the creek and river. The project will eliminate the non-permitted septic systems and construct a new wastewater system to properly treat wastewater prior to its discharge into the waterways.

07011-003 Keg Creek Watershed Final Report

Mills County proposes to reduce the identified impairment of the watershed, Keg Creek, by eliminating one of the main reasons for the impairment - non-conforming, on-site septic tanks that allow effluent to drain into the creek from the unincorporated community of Mineola. This has been identified by the county as a major priority. Therefore, the county proposes to construct a collection system and lagoon treatment facility, which would eliminate effluent from draining into Keg Creek. Regional Water will own, operate, and manage the collection and treatment systems in Mineola for Mills County.

09014-010 Lytle Creek Watershed Final Report

Brief Project Summary (no greater than this space allows): Leisure Lake is a 20 acre water body located in northwest Jackson County with a 2,581 acre drainage area. This portion of the Maquoketa Watershed including the lake is a tributary to Lytle Creek which drains into the North Fork Maquoketa River and into the Maquoketa Watershed. Portions of the Lytle Creek and North Fork Maquoketa River are on the 303(d) impaired waterbodies list. The project area includes a community of 370 residential properties and one business that currently has no central waste water collection and treatment system. The County Sanitarian estimates at least 225 of these properties do not have properly operating septic systems and ultimately drain their wastewater into the lake. The purpose of this project is to construct a wastewater collection and treatment facility to improve water quality in the creek and river. The project will eliminate the non-permitted septic systems and construct a new wastewater system to properly treat wastewater prior to its discharge into the waterways.

Dynamic Facility Location with Modular Capacities : Models, Algorithms and Applications in Forestry

Les décisions de localisation sont souvent soumises à des aspects dynamiques comme des changements dans la demande des clients. Pour y répondre, la solution consiste à considérer une flexibilité accrue concernant l’emplacement et la capacité des installations. Même lorsque la demande est prévisible, trouver le planning optimal pour le déploiement et l'ajustement dynamique des capacités reste un défi. Dans cette thèse, nous nous concentrons sur des problèmes de localisation avec périodes multiples, et permettant l'ajustement dynamique des capacités, en particulier ceux avec des structures de coûts complexes. Nous étudions ces problèmes sous différents points de vue de recherche opérationnelle, en présentant et en comparant plusieurs modèles de programmation linéaire en nombres entiers (PLNE), l'évaluation de leur utilisation dans la pratique et en développant des algorithmes de résolution efficaces. Cette thèse est divisée en quatre parties. Tout d’abord, nous présentons le contexte industriel à l’origine de nos travaux: une compagnie forestière qui a besoin de localiser des campements pour accueillir les travailleurs forestiers. Nous présentons un modèle PLNE permettant la construction de nouveaux campements, l’extension, le déplacement et la fermeture temporaire partielle des campements existants. Ce modèle utilise des contraintes de capacité particulières, ainsi qu’une structure de coût à économie d’échelle sur plusieurs niveaux. L'utilité du modèle est évaluée par deux études de cas. La deuxième partie introduit le problème dynamique de localisation avec des capacités modulaires généralisées. Le modèle généralise plusieurs problèmes dynamiques de localisation et fournit de meilleures bornes de la relaxation linéaire que leurs formulations spécialisées. Le modèle peut résoudre des problèmes de localisation où les coûts pour les changements de capacité sont définis pour toutes les paires de niveaux de capacité, comme c'est le cas dans le problème industriel mentionnée ci-dessus. Il est appliqué à trois cas particuliers: l'expansion et la réduction des capacités, la fermeture temporaire des installations, et la combinaison des deux. Nous démontrons des relations de dominance entre notre formulation et les modèles existants pour les cas particuliers. Des expériences de calcul sur un grand nombre d’instances générées aléatoirement jusqu’à 100 installations et 1000 clients, montrent que notre modèle peut obtenir des solutions optimales plus rapidement que les formulations spécialisées existantes. Compte tenu de la complexité des modèles précédents pour les grandes instances, la troisième partie de la thèse propose des heuristiques lagrangiennes. Basées sur les méthodes du sous-gradient et des faisceaux, elles trouvent des solutions de bonne qualité même pour les instances de grande taille comportant jusqu’à 250 installations et 1000 clients. Nous améliorons ensuite la qualité de la solution obtenue en résolvent un modèle PLNE restreint qui tire parti des informations recueillies lors de la résolution du dual lagrangien. Les résultats des calculs montrent que les heuristiques donnent rapidement des solutions de bonne qualité, même pour les instances où les solveurs génériques ne trouvent pas de solutions réalisables. Finalement, nous adaptons les heuristiques précédentes pour résoudre le problème industriel. Deux relaxations différentes sont proposées et comparées. Des extensions des concepts précédents sont présentées afin d'assurer une résolution fiable en un temps raisonnable.

The meta-object facility typed

The Object Managment Group’s Meta-Object Facility (MOF) is a semiformal approach to writing models and metamodels (models of models). The MOF was developed to enable systematic model/metamodel interchange and integration. The approach is problematic, unless metamodels are correctly specified: an error in a metamodel specification will propagate throughout instantiating models and final model implementations. An important open question is how to develop provably correct metamodels. This paper outlines a solution to the question, in which the MOF metamodelling approach is formalized within constructive type theory.

Re-framing risk transfer to assess integrative partnership opportunities: the S.A.R. approach and the AIG/BID/CNO regional surety bond facility of 2007

Identificar, compartilhar e gerenciar os riscos de contratar são preocupações que impedem o estabelicmento e a administração das Parcerias Públicos Particulares (PPP). Porem, gerentes das entidades públicas, bancos de formento, construtoras e seguradoras pesquisam e utilizam muitas técnicas para enfrentar a avaliação e gerenciamento dos riscos. A transferência de risco é uma indicação dos chamados benefícios que são inspirados pelos PPP, contudo devido às realidades contratuais e conceptuais, a entidade de cede o risco (o partido público) permanece quase sempre como o portador final do risco. Conseqüentemente, o partido público retem um interesse de resistência na gerência total destes riscos cedidos. Esta dissertação explora alguns defeitos das aproximações comuns a conceituar a gestão de risco no contexto de um PPP. Focalizando os conceitos da interdependência e da reciprocidade e usando na decisão para transferir o risco do projeto, esta dissertação molda a decisão para transferir o risco nos termos das realidades interdependentes de relacionamentos sistemáticos, alargam os conceitos técnicos do risco e da avaliação de risco, considerando o uso reflexivo das diferenças na analise de um estudo de caso. O autor explora estes conceitos em uma análise da decisão de um gerente de risco da empresa de construção civil brasileira Construtora Norberto Odebrecht (ODB) para projetar uma facilidade inovadora da ligação de garantia com Inter-American Development Bank (BID) e uma seguradora, American International Group (AIG), um negócio que ganhe o reconhecimento Trade Finance Magazine’s 2007 deal of the year. O autor mostra que por compreender a transferência de risco nos termos abordados nesta dissertação, um atore que transfere o risco pode identificar e criar mais oportunidades de estabelecer relacionamentos em longo prazo, através dos processos que a literatura atual do PPP ainda não considere. Os resultados devem fornecer contribuições para a pesquisas sobre a transferência do risco do projeto, na cooperação entre organizações e na seleção do sócio do projeto do potencial.

Diagnóstico e avaliação das áreas de destino final dos resíduos sólidos urbanos no estado do rio grande do norte

This work aims to present the diagnosis and the evaluation of areas of final destination of urban solid waste in Rio Grande do Norte (RN) state. The survey was based on the experience of the State of São Paulo, which made its first inventory in 1997, through its Companhia de Tecnologia de Saneamento Ambiental CETESB. The methodology for the structuring of diagnosis was the Índice de Qualidade de Aterros de Resíduo -- IQR, developed by the Institute for Technological Research of São Paulo (ITRP). The calculation is based on the completion of a matrix that contains information about the main features of the site, infrastructure and operating conditions of the area of waste disposal. This study intends to subsidize the state government of Rio Grande do Norte through its State Secretariat of Environment and Water Resources and the Instituto de Desenvolvimento Sustentável e Meio Ambiente do RN (IDEMA), as well as federal, state and municipal authorities, in the definition of public policies for integrated management of municipal solid wastes to take account of environmental preservation and improvement of sanitary conditions of Natal-RN population.

Incorporação de lodo de esgoto na massa cerâmica para fabricação de tijolos maciços: uma alternativa para a disposição final de resíduo

The disposal of sewage sludge is a growing problem face up to management of sanitary sevices. Otherwise, because its making process characteristic, the Ceramic Industry can tolerate the presence of this wastes as raw material. This study has as object to confirm the use of the sewage sluge in the Ceramic Industry like a sustentable alternative for its disposal. Futhermore, this study quests to evaluate the maximum proportion for incorporation of sludge wich result in technically and enviromentally suitable bricks. For found this proportion, the research consisted of (1) making of bricks in full scale, adde up 0%, 5%,10%, 15%, 20%, 25%,30%, 35% e 40% sludge, with size 220x105x45 mm, hand-molded by rammer and baked by industrial kiln; and (2) tecnical and enviromental evaluation of this bricks, according to Brazilian norms. The raw material uses were two distinct clays come from Goianinha/RN and sewage comes from a septic system tank and pumped into tank vehicle, of Natal/RN. The technical evaluation allowed to conclude the addiotion of the sludge brings about signifcant lost of mass and the water absorption grew up according to increase of sludge: every sludge-amended clay bricks absorved more water than control group. Thus, the compressive strength was signicantly decreased because the increase of sludge: bricks with 5% sludge added lost 45% of strength achieved at control group; the bricks made with 10 and 20% lost almost 70% of bigger strength. With up to 25% sludge added to the bricks, the streght decreased over 90%. Concerning heavy metal leaching, the two maximum proportion wich have tecnical approval, it means bricks sludge added with 15 and 20%, can say there is no risk of enviromental contamination using those bricks. This way, in this work context, it can to conclude the maximum proportion atends the technical and enviromental criterion is 20%
