Texto completoAbstract : The main goal of the doctoral project is to determine to what extent the optimal integration of single-phase ejectors might reduce the large amount of energy required to capture carbon dioxide from electric power generation facilities. More specifically, the objective is to determine if ejectors can be advantageously integrated into a post-combustion absorption/desorption carbon dioxide (CO2) capture process using monoethanolamine (MEA). The integrated ejectors will use waste heat of 100 °C from the electric power plant. The upgraded waste heat can partially replace valuable turbine steam that would otherwise be taken from the power plant. The second objective of the thesis is to experimentally evaluate the performance of a steam ejector where the ejector secondary fluid is a mixture of steam and a non-condensable gas, in this case CO2. Two steam ejector nozzles, of 4.60 mm and 4.23 mm diameter, were evaluated over a range of secondary fluid CO2 levels, up to 42% by mass. The primary pressure was maintained at 450 kPa with 10 °C superheat and the secondary pressure was 70 kPa. It was found that the critical exit pressure did not change as the mass fraction of CO2 in the secondary fluid increased. The entrainment ratio, however, increased approximately linearly over the experimental range. An improvement of 23% in the entrainment ratio, as compared with pure steam, was found when the secondary fluid contains 42% CO2 by mass. This behaviour is in sharp contrast to the experimentally observed behaviour of a pure steam ejector, where an increase in entrainment ratio comes at the expense of a decrease in the ejector exit critical pressure. Three published papers investigated various scenarios for the integration of a steam injector into an absorption/desorption post-combustion capture process. The reference solvent was 20% weight monoethanolamine (MEA). Three principal configurations were studied, according to the choice for the liquid flow used to produce the ejector secondary steam: ejector on condensate, ejector on lean or ejector on rich. The first journal publication focused on the desorption process and presented a shortcut method based on CO2-MEA-H2O equilibrium vapour liquid data. The simulations revealed reductions in the required amount of valuable energy from 10 to 25%. A commercial process simulator, Aspen Plus, was used for two other publications. In the second journal publication, the kinetic rate-based module was employed to model the absorber and desorber, providing energy evaluations closer to values in the open literature. A study was included comparing preheating the primary steam with waste heat or by heat integration. The rate-based simulation found valuable energy savings of 10 to 14%, with the "ejector on condensate" and "ejector on lean" again being the advantageous scenarios.

Texto completoSouzy, Nicolas. "Experimental study and improvement of mass transfer in vertical bubble columns". Thesis, Lyon 1, 2014. http://www.theses.fr/2014LYO10201/document.
Texto completoBubble column are involved in many industrial fields ranging from chemical industry to mineral processing. It recently became an industrial stake for the production of micro-algae intended for medicinal use, food or energy: the oxygen and carbon dioxide concentrations can be controlled via the efficient mass transfer induced by the significant gas-liquid interfaciale area into the bubble column. Firstly, experimental closed-loop study has been carried out to simulate the passage of gas in a succession of columns in series. The associated theoretical model confirms the critical importance of the bubble diameter for mass transfer.Therefore, an innovative Micro-Bubble Generator (MBG) has been designed and tested. The prototype is able to produce micro-bubbles of average diameter Dbubble = 0.252 mm. The invention has been officially declared. The last chapter aims at improving data treatment methods for Planar Laser-Induced Fluorescence (PLIF), which enables to obtain experimentally mass transfer coefficient kl through concentration measurements. The first presented correction takes into account variations of the fluorescence extinction due to pH during the calibration step, and has been evaluated on CO2 concentration measurement in the wake of a free rising bubble. The second proposed correction should be applied when the length in the measurement region over which pH variations are observed increases: variations of the extinction coefficient will affect the local incident light intensity and therefore the measurements. The need for this correction has been illustrated on a test case in the wake of a cloud of free rising bubbles

Texto completoLo sviluppo sostenibile rappresenta una delle più importanti sfide che oggi l’umanità deve affrontare. L’uso razionale delle risorse energetiche e l’aumento dell’efficienza dei sistemi che le utilizzano, è un importante obiettivo per tutti i contesti della vita moderna, dal settore industriale, ai trasporti, agli elettrodomestici di uso quotidiano. L’interesse verso questo tema è giustificato, non solo dal prezzo dell’energia in potenziale aumento, ma anche dalla necessità di ridurre le emissioni dei gas che sono ritenuti responsabili del riscaldamento globale. Questo lavoro si inquadra nello studio di soluzioni tecnologiche innovative volte al miglioramento dell’efficienza energetica di apparecchiature domestiche, più precisamente macchine che operano con un ciclo inverso a compressione di vapore. In particolare verrà fatto riferimento ad asciugabiancheria a pompa di calore, refrigeratori domestici e pompe di calore per il riscaldamento di acqua calda sanitaria. Come è noto, le asciugatrici domestiche realizzano un processo termodinamico che richiede un elevato dispendio energetico. Per questo motivo negli ultimi anni si è dato molto spazio alla ricerca di soluzioni che ne possano ridurre i consumi elettrici, trovando nella tecnologia della pompa di calore una significativa possibilità di miglioramento. Oggi l’attenzione è rivolta a incrementarne ulteriormente l’efficienza energetica e a trovare dei sostituiti ai tradizionali fluidi refrigeranti alogenati per ridurne l’impatto sull’ambiente. Poiché non è né tossica né infiammabile, l’anidride carbonica è perfettamente compatibile con gli ambienti domestici, ed è vista come un possibile sostituto dei composti sintetici. In questo lavoro il ciclo transcritico ad anidride carbonica viene messo a confronto, sia su base teorica che sperimentale, con il ciclo subcritico a R134a. I risultati di questa indagine mostrano buone prospettive per l’impiego della CO2 in questa applicazione. Nella sezione successiva verranno approfonditi aspetti teorici e tecnologici delle pompe di calore dedicate al riscaldamento di acqua calda sanitaria, applicazione in cui il ciclo transcritico ad anidride carbonica risulta essere molto efficace. L’analisi prevede lo studio di logiche di controllo di tipo adattativo per l’ottimizzazione della pressione superiore di ciclo. Sarà inoltre presentato uno studio sperimentale di macchine operanti con gas-cooler a piastre a doppia parete, impiegato per ridurre il rischio di contaminazione del circuito idraulico. Verranno poi approfondite alcune tematiche legate al miglioramento dell’efficienza energetica dei refrigeratori domestici. Si riportano i risultati di un’indagine sperimentale condotta su un frigorifero domestico di tipo “sottotavolo”, i cui consumi elettrici sono stati monitorati al variare della frequenza ciclica di accensione del compressore. Per questa apparecchiatura è stata registrata una significativa riduzione dei consumi ad elevati frequenze. Per approfondire ulteriormente questi temi, mediante simulazione numerica, è stato sviluppato un modello per evaporatori in regime di funzionamento dinamico, seguendo uno schema di tipo “moving boundary”. Un’opportuna scelta delle variabili di stato (nello specifico, variabili corrispondenti a proprietà medie e non a grandezze di confine del modello) ha permesso di tenere conto delle variazioni nel tempo del grado di vuoto medio della zona bifase e di conseguire una maggiore velocità di simulazione dei transitori di avviamento del compressore. Questo modello è stato quindi sviluppato appositamente per la simulazione di refrigeratori domestici che operano in regime ciclico di funzionamento. Infine, nell’ottica del miglioramento dell’efficienza dei refrigeratori domestici combinati di tipo total-no-frost, viene presentata una soluzione innovativa per il ciclo termodinamico. In queste apparecchiature il vano dei prodotti freschi viene di solito raffreddato facendo circolare una piccola portata d’aria proveniente dal vano dei prodotti surgelati. Questo tipo di funzionamento è inefficiente, in quanto la potenza frigorifera viene erogata al più basso livello di temperatura. La soluzione studiata prevede, invece, di convogliare alternativamente verso l’evaporatore due flussi d’aria che raffreddano distintamente i due vani refrigerati. Così facendo è possibile differenziare due livelli di temperatura per la produzione della potenza frigorifera, conseguendo un aumento dell’efficienza energetica quando l’unità opera al raffreddamento del vano a temperatura positiva.

Texto completoThe focus of this study is enabling the improvement of an organic soft soil by means of pozzolanic reaction. A several variables were evaluated, such as type of stabilization, pure or mixed with other materials and two distinct curing temperatures. In order to facilitate and optimize the molding, curing, unmolding and rupture of the specimens, a methodology was developed for processing the mixtures. The binding agents used were cement and quicklime. Mixed with the binding agents, electric arch furnace slag, ladle furnace slag, gypsum and phosphoric gypsum were added. The used curing temperatures were 20 and 50 degrees Celsius. The soil used in this study is a very soft organic clay with natural moisture content ranging from 85% to 100% obtained in Nova Santa Rita, Rio Grande do Sul, Brazil. It was chemically and physically characterized. The chemical characterization consisted of loss of ignition tests, elemental analysis, X-ray diffraction and the fractionation of organic matter. The improvement of this material with the use of the previously mentioned binders proved possible within the range of variation of the analyzed variables. The best results were obtained when using cement, and the larger the content of cement the greater the added strength. As for the quicklime, an optimum lime content was observed. From this optimum point onwards any addition of quicklime will result in diminishment of the gained strength as such, when utilizing this method in a real project, one must be aware of this diminishment so as to avoid detrimental results. Utilized with the binding agents analyzed in this material, the electric arc furnace slag and the ladle slag were shown to be inefficient when evaluating the gain of strength. Gypsum and phosphoric gypsum led to considerable gain in strength when mixed with cement, especially in high dosages. When mixed with quicklime, however, the effect was a drop of up to 50% in the gain of strength. The curing temperature was effective in accelerating pozzolanic reactions for both the cement and the quicklime. It was possible to adapt a dosing methodology using the function porosity/volumetric cement content into soil/cement mixtures.

Texto completoEls aiguamolls construïts horitzontals de flux subsuperficial (AC HFSS) són sistemes naturals de tractament d'aigua residual i constitueixen un entorn favorable per a la implementació de Piles de Combustible Microbianes (PCM). Les PCM son sistemes bioelectroquímics que permeten la eliminació de la matèria orgànica i la generació d'electricitat de forma simultània. A més a més de la generació d'electricitat, les PCM implementades en AC, poden generar altres beneficis que són d'especial importància en el context dels AC. El monitoreig semi-continu de la qualitat de l'aigua que entra i surt dels sistemes, la millora de la eficiència de tractament dels AC o el seguiment de l'estat de colmatació del llit de grava dels AC són alguns dels potencials beneficis resultants. Tot i això, les PCM implementades en AC, constitueixen un camp de recerca molt recent en el que encara falten coneixements específics tant sobre el disseny dels AC com sobre la operació de les PCM per optimitzar la sinèrgia entre ambdues tecnologies. Així doncs, l'objectiu de la tesi que es presenta és el de determinar, quantificar i maximitzar els beneficis que resulten de la sinergia entre els AC HFSS i les PCM. Per assolir els objectius d'aquest estudi s'han utilitzat dos dissenys experimentals diferents: PCM-AC implementades en sistemes a escala pilot i a escala de laboratori. Els resultats obtinguts demostren que el flux hidràulic continu i els aiguamolls plantats generen gradients redox superiors en el llit de grava quan es comparen amb els aiguamolls no-plantats operats en flux discontinu. A més a més, les PCM-AC generen corrents elèctrics superiors quan el tractament primari aplicat és el reactor HUSB en comparació al decantador convencional. La relació òptima de superfície càtode : ànode obtinguda és de 4:1. Finalment, per tal de maximitzar el potencial de les PCM-AC, cal situar el càtode en posició semi-submergida i a una distància de 10 cm de l'ànode. Tot i això, quan s'apliquen les condicions d'operació dels AC i l'arquitectura de les PCM òptima, l'energia produïda per les PCM-AC pot cobrir només entre el 3 i el 14% d'una planta de tractament d'aigua residual constituïda per aiguamolls construïts. Així doncs, tot i que l'energia generada per les PCM-AC constitueix un resultat positiu, no esdevé el benefici principal. En termes de les seves aplicacions ambientals, les PCM-AC han demostrat poder millorar la capacitat de tractament dels AC. La concentració de matèria orgànica a l'efluent de les PCM-AC connectades fou significativament inferior que a l'efluent dels sistemes no connectats. A més a més, les PCM-AC han mostrat potencial per a la determinació de la DQO. Tot i això, hi ha molts factors que poden afectar la precisió, la repetibilitat i la estabilitat operativa del sistema de manera que la seva viabilitat com a biosensor passa per utilitzar-les com a eina de bioindicació qualitativa. Per últim, les PCM-AC també tenen potencial per a la determinació en continu del grau de colmatació dins el llit de grava dels AC. De l'estudi dels impactes ambientals associats a la implementació de les PCM en els AC se'n conclou que els sistemes amb l'ànode de grafit constitueixen la millor alternativa en termes d'impactes ambientals per reduir tant la superfície dels aiguamolls com la seva petjada ecològica (sobre un 20% de reducció). Finalment, tot i trobar-se en un estadi d'estudi prematur, les PCM implementades en AC representen una tecnologia innovadora capaç de produir energia alhora que es tracta l'aigua residual. Encara que, si es considera de forma exclusiva el guany energètic, la sinèrgia entre ambdues tecnologies pot no semblar molt atractiva, les PCM-AC constitueixen una tecnologia molt prometedora pel que fa a les seves aplicacions ambientals tals com la millora de la eficiència de tractament dels AC o la seva utilització per a la determinació del contingut de matèria orgànica en l'aigua residual i el grau de colmatació dels sistemes.

Texto completoThis paper shows a application of the concepts of lean production in a continuous process company. There is a misconception from some companies\' part that because they have continuous process, they fit more the mass production principles, therefore it is not valid to them the concept of lean production. There is also the belief, questionable as well, that they are naturally lean, due to the high level of automation with little handling and discret movements. This paper shows that this is not true and that continuous process company can benefit considerably from the application of the lean production concepts. It is presented here a bibliography review of the main tools and concepts of lean production. It is also presented a documented case of the application of these concepts in a chemical industry with continuous process. Next, the case of the application of lean production is showed, conducted by the author in a big company of termoplastic in the state of São Paulo that presents the characteristics of continuous process. The results of this application is presented, enfasizing the results obtained, it was obtained 21% of reduction in the screp indicator and 14% in the midium time of the set up and also some comments about the application of the lean production in these kinds of companies.

Este trabalho visa a otimização não-linear restrita usando o Método das Tolerâncias Flexíveis (FTM) e na aplicação do mesmo na síntese de sistemas de integração mássica. A integração mássica é uma técnica que permite a compreensão global do fluxo de massa dentro do processo, e emprega tais conhecimentos na identificação de melhorias de desempenho e otimização da geração e mapeamento de espécies ao longo do processo. A integração de massa baseia-se nos princípios fundamentais da engenharia química combinada com a análise do sistema usando ferramentas gráficas e de otimização. Neste contexto, o método direto de otimização foi usado como base para melhorias a fim de tornar possível sua aplicação em problemas de síntese de processo, especialmente a integração de massa. O Método das Tolerância Flexíveis é um método direto de otimização que apresenta algumas vantagens como simplicidade e a capacidade de lidar com igualdade e desigualdade sem empregar o cálculo de derivadas. O método utiliza duas buscas para satisfazer a restrição de viabilidade. A busca externa é uma variação do método de Nelder-Mead (ou o método Poliedro Flexível ou FPM) que minimiza a função objetivo. A busca interna minimiza o valor da função formada pelas restrições de igualdade e/ou desigualdade do problema. Esta busca interna pode ser realizada por qualquer método de otimização não linear irrestrita. Neste trabalho, o método das tolerâncias flexíveis foi hibridizado com diferentes métodos irrestritos para realizar a busca interna: BFGS (Método de Broyden, Fletcher, Goldfarb and Shanno) e Powell modificado. O método estocástico do Enxame de Partículas (PSO) também foi empregado para efetuar a inicialização e geração do ponto de partida viável para sequencial aplicação do método deiii terminístico (FTM e modificações). Outras modificações testadas foram o escalonamento de variáveis, a utilização de parâmetros adaptativos Nelder-Mead e a adição de uma barreira. Os algoritmos propostos neste trabalho foram aplicados a um conjunto de problemas nãolineares restritos que compreende problemas de otimização reais. Os códigos que apresentaram melhor desempenho foram o Método Modificado das Tolerâncias Flexíveis com variáveis escalonadas (MFTMS) e o híbrido FTMS-PSO (o Método das Tolerância Flexíveis com escalonamento de variáveis e hibridizado com PSO). Estes melhores códigos foram aplicados com sucesso na solução de problemas de integração em massa. Os resultados encontrados neste trabalho demonstram a capacidade de métodos simples e diretos em lidar com problemas de otimização complexos, como os problemas de integração mássica. Além disso, um problema inédito de integração mássica proposto neste trabalho, a integração mássica de uma biorefinaria de cana-de-açúcar incluindo 1G, 2G e 3G, foi resolvido com êxito com os métodos propostos neste trabalho (MFTMS e FTMS-PSO). A primeira geração (1G) inclui a produção de etanol utilizando o caldo da cana-de-açúcar e produção de vapor e eletricidade pela cogeração. A segunda geração (2G) utiliza a biomassa lignocelulósica para produção de etanol pela rota bioquímica. A terceira geração (3G) inclui a utilização de algas para produção de biocombustíveis (etanol e biodiesel). Os resultados deste estudo de caso fornecem uma indicação de uma forma economicamente viável de conseguir avanços substanciais em termos de consumo de água e redução da poluição.
This work is focused in constrained nonlinear optimization using the Flexible Tolerance Method (FTM) and in applying in systems synthesis of mass integration. Mass integration is a technique that allows an overall understanding of the mass flow within the process, and employs such knowledge in identification of performance improvements and optimization of the generation and mapping of species throughout the process. The mass integration is based on the fundamental principles of chemical engineering combined with system analysis using graphical and optimization tools. In this context, the direct method of optimization was used as the basis for improvements in order to make possible the application in process synthesis problems, especially mass integration. The Flexible Tolerance Method is a direct method of optimization that present some advantages as simplicity, the ability to lead with equality and inequality constraints without employ derivative calculus. The method uses two searches to satisfy feasibility constraint. The external search is a variation of the Nelder-Mead method (or the Flexible Polyhedron method or FPM). This one seeks to minimizes the objective function. The internal search minimizes the value of the positive function for all equality and/or inequality constraints of the problem. This internal search can be performed by any unconstrained nonlinear optimization method. In this work, the Flexible Tolerance Method was hybridized with different unconstrained methods to perform the inner search: the BFGS (Broyden, Fletcher, Goldfarb and Shanno Method) and the modified Powell. The stochastic PSO method was also employed to perform the initialization and generation of the feasible start point to sequential application of the determination method i (FTM and modifications). Others modifications tested were the scaling of variables, the use of Nelder-Mead adaptive parameters and the addition of a barrier. The algorithms proposed in this work were applied to a benchmark of constrained nonlinear problems that comprises real world optimization problems. The best codes obtained were the Modified Flexible Tolerance Method Scaled (MFTMS) and the hybrid FTMS-PSO (the Flexible Tolerance Method with scaling of variables hybridized with PSO (Particle Swarm Optimization)). These best codes were applied with success in the solution of mass integration problems. The results found in this work demonstrate the capacity of simple and direct methods in deals with complex optimization problems, as the mass integration problems. Additionally an inedited problem of mass integration proposed in this work, the mass integration of 1G, 2G and 3G sugarcane biorefinery was successful solved with the methods proposed in this work (MFTMS and FTMS-PSO). The first generation (1G) includes the ethanol production using the sugarcane juice and production of vapor and electricity throughout cogeneration. The second generation (2G) includes the ethanol production using the lignocellulosic biomass feedstock via the biochemical route. The third generation (3G) includes the algae use for production of biofuels (ethanol and biodiesel). The findings of this study case provide an indication of an economically viable way of achieving substantial advances in terms of water consumption and pollution reduction.

Texto completoThe geocell was initially designed to improve the soil bearing capacity. However, this geosynthetic also can be used as a retaining wall, facing for reinforced soil structures, slope protection against erosion and channel lining. In the soil bearing capacity improvement the geocell can be applied as reinforcement of foundation, soft soil embankments and roads and railroads. In the literature there are few methods for predicting bearing capacity of geocell-reinforced soil, however with disabilities that limit their applicability. In this regard, a new method for predicting the bearing capacity of geocell-reinforced soils is presented herein, taking into account the soil foundation resistance and the geocell reinforcement mechanisms, namely, stress dispersion effect and confinement effect. The present method is verified with the results of laboratory plate load experiments by several authors and numerical simulations, and compared with other calculation methods. The results indicated that the calculated results obtained from this method were very close to experimental and numerical results, better than other methods. This method also proved to be a good approach for different geocell characteristics (geometry and constitution material), for foundation soil and geocell infill (different types of sand and clay) and for loading shape (circular, rectangular and strip). In the last Chapter, the method has been applied in foundation and soft soil improvement and satisfactory verified by numerical simulations.

Texto completoWith a growing need for the use of more sustainable materials in construction, there is a great search for new substances that can meet our needs in a "cleaner" way. The present work aims to propose a dosing methodology for obtaining artificially cemented soils, with certain strengths and stiffness, so that they are durable, with the addition of different residues. The initially studied soil is the Osório sand and the residues are carbide lime and glass powder. The carbide lime basically consists of calcium hydroxide and the glass powder consists of silica in the amorphous state, thus generating a great combination for the occurrence of the pozolanic reactions. The proposed dosage methodology relates the properties of the materials with the factor η/Biv0.28, at the seven days of curing, in which η is the porosity of the artificially cemented soil and Biv is the volumetric content of the cementitious agent inside it (in this case powder glass and carbide lime) The external exponent 0.28 resembles that found in other dosing methodologies for artificially cemented soils with Portland cement. The methodology led to a unique correlation for all the dosages used. To validate the hypothesis which was raised, tests were carried out with different curing periods (180 days), different residues (rice husk ash) and a different soil (Botucatu sandstone), reaching optimum correlations. The data obtained in this research were compared with the results of other researchers who used lime with fly ash from coal plants together with hydrated lime and from other works that used Portland cement, all to create artificially cemented soils, and, once again, the proposed methodology proved to be excellent. It was also possible to normalize all the results of stiffness, strength and durability thus obtaining unique equations as a function of η/Biv0.28 for all materials analyzed, reaching a correlation with more than 1000 points.

Texto completoThe brown rot caused by the fungus Monilinia fructicola (Wint.) Honey, is the main disease in stone fruit trees (Prunus spp.). It can be found in almost all fruit orchards, causing severe losses to fruit growers. The main symptoms of this disease are the blossom blight, twig cankers and necrosis and, fruits rot. Thus, the economic losses of brown rot may occur since flowering, extending to the pre-and post-harvest fruit phases. The aim of this study were (i) to test the brown rot reaction of different peach genotypes, identifying the resistant or tolerant ones to brown rot on flowers, (ii) to identify resistance and/or tolerance sources to this fruit disease and (iii) to identify resistance mechanisms associated with the physical, chemical and biochemical characteristics in peach fruits, iv) to identify superior genotypes for biochemical characteristics; v) to study the genetic divergence of peach genotypes on the UTFPR collection. The work was carried out at Laboratório de Fitossanidade, Universidade Tecnológica Federal do Paraná (UTFPR) – Campi Dois Vizinhos and Pato Branco, in the 2009/2010 and 2010/2011 production cycles. The genotypes analyzed were the peach collection of the UTFPR, in Pato Branco, PR. Five and 16 genotypes were tested in the first and second cycles, respectively, in relation for flowers brown rot reaction. For fruit disease reaction 26 and 29 peach genotypes were tested in the production cycles 2009/2010 and 2010/2011, respectively. The tests aimed to evaluate the flower incidence and the fruits incidence and severity, after pathogen inoculation. The physical-chemical and biochemical fruit characteristic, and were evaluated as well as their relation if any with epidemiological variables. Genotypes were also determined by biochemical fruit characteristics. The genetic divergence among peach genotypes for epidemiological variables and biochemical fruit characteristics was also studied. Different levels of susceptibility to blossom blight were obtained, being the 'Cascata 1070' and 'Cascata 1055' the ones with lowest susceptibility, demonstrating potential for use in orchards or as parents in future breeding programs. The 'Tropic Beauty', 'Cascata 962', 'Conserva 1187', 'Kampai', 'Cascata 1063', 'Tropic Snow' and 'Rubimel' peach genotypes showed the lowest incidence and severity for brown rot in the 2009/2010 and 2010/2011 cycles, which indicates them as disease possible tolerant. There was no correlation between the blossom blight incidence percentage and the brown rot fruit incidence and severity. There were correlation between TSS, pH, reducing sugars, total amino acid content and PAL enzyme for brown rot reaction.

Texto completoIn a world obsessed by innovation and thirsty for speed, it can be seen the need for constant search for solutions in all areas of knowledge. Within Geotechnical Engineering, it can be obtained with geotechnical proposals that provide reduced cost, including preservation of natural resources. Promoting the use of soils that do not have adequate geotechnical characteristics is one of the points observed in geotechnical research innovations. Adjusting the soil strength characteristics and initial shear modulus values, improving it with the use of standard cements and alternative cements obtained with the addition of waste is the line that leads this research, which has as main objective the verification of the influence of the addition of distinct binders in an organic soft soil of Porto Alegre - RS, Brazil. The mixtures were composed of a single soil matrix and various types of binders, namely: early strength Portland cement, early strength Portland cement mixed with ground furnace slag (coarse particles), early strength Portland cement mixed with ground furnace slag (fine particles), early strength Portland cement mixed with gypsum (di-hydrate), early strength Portland cement mixed with gypsum (hemi-hydrate) and early strength Portland cement mixed with quicklime. The binder amounts were set at 75 kg/m³, 125 kg/m³, 175 kg/m³, 225 kg/m³ and 275 kg/m³ in mass of binder per volume of soil, and moisture content of 120% regarding final mixture. In addition to changes in the amount and type of binders, three cure times were also stipulated 7, 28 and 90 days. In order to assess which mixture behaves more adequately, strength tests and initial shear modulus measures were carried out. In order to foreseen the mechanical behavior of the blends, a methodology that takes into account the porosity/volumetric cement content ratio ( /Civ), as well as the well-known water/cement ratio (a/c) are used. Results indicated that the increase in the binder content leads to an increase in compressive strength and also in the initial shear modulus, for all curing times. Both /Civ and a/c are capable to predict the unconfined compressive strength and the initial shear modulus. The studied technique of improving organic soft soils with various types of binders was successful, thus obtaining different characteristics in terms of curing time, binder content and type of binder added to the soil.

Texto completoIntroduction
Current instrumentation makes it possible to measure vehicle emissions with high temporal resolution. But the increased resolution of emissions signals does not equate with increased accuracy. A prerequisite for the derivation of accurate emission factors from instantaneous vehicle emissions data is a fine allocation of measured mass emissions to recorded engine or vehicle states. This poses a technical challenge, because vehicle emission test facilities are not designed to support instantaneous emissions modelling, and they introduce distorting effects that compromise the instantaneous accuracy of the measured signals.
Methodology
These distorting effects can be compensated through a combination of physical modelling and data post-processing. The main original contribution of this dissertation is a novel methodology for the compensation of instantaneous emission signals, which is fully described herein. Whereas previous methodologies relied on systems theory modelling, and on comprehensive testing to model the sub-systems of the measurement setup, the alternative approach uses CO2 as a tracer of the distortions brought about by the measurement setup, which is modelled as a 'lump' system.
Conclusions The main benefits of this methodology are its low burden of experimental work and its flexibility. Furthermore, it has been fully implemented in the 'esto' software tool, which can perform the compensation of emission signals with minimal user intervention and speed up the creation of engine emission maps.

This study conducted an array of tests to characterize the physic-mechanical and hydraulic properties of mixtures of iron ore tailings from the processing of iron ore, with and without addition of CP II-E-32 Portland cement with slag, aiming the application in layers of road pavements and construction of embankments. Tailing samples were obtained from specific points of iron ore processing by flotation and magnetic concentration. Tailings were termed flotation and concentration and collected from the processing plant Alegria, owned by Companhia Vale S.A. To meet the proposed goals were evaluated geotechnical parameters used in the characterization of pavement layers by means of an experimental program that included the following laboratory tests: (i) particle size tests, (ii) Atterberg limits (LL and LP), (iii) solid unit weight (iv) compaction, (v) CBR, (vi) compressive strength, (vii) analysis of immersion of specimens, (viii) durability by wetting and drying, (ix) permeability (x) application of the MCT methodology (Mini-MCV compaction and weight loss by immersion). The mixture with highest CBR value, with 60% flotation + 40% concentration, was identified by the TRB classification system and classified as A-4(1) and exhibited particle size composition compatible for use as a sub-base material according to DNIT specifications (2006). Nevertheless, it has a coefficient of uniformity between 5 and 6, which indicates a uniform grain size, reflecting negatively on the hydromechanical behavior. For application as a pavement base, the mixture should be studied with an increase of 8.5% cement, percentage determined by this work, to meet the average strength of 2.1 MPa, required for soil-cement mixtures according to ABCP (1980).
Neste trabalho, foi realizada uma campanha de ensaios de caracterização das propriedades físico-mecânicas e hidráulicas de misturas de rejeitos provenientes do beneficiamento de minério de ferro, com e sem adição de cimento Portland composto com escória, tipo CP II-E-32, visando à aplicação em camadas de pavimentos rodoviários e à construção de aterros. As amostras de rejeito foram obtidas de pontos específicos dos processos de beneficiamento do minério de ferro pelos processos de flotação e concentração magnética. Os rejeitos foram denominados de flotação e concentração e coletados na usina de beneficiamento Alegria, pertencente à Companhia Vale S.A. Para atender aos objetivos propostos, foram avaliados parâmetros geotécnicos utilizados na caracterização de camadas de pavimentos por meio de um programa experimental que abrangeu os seguintes ensaios de laboratório: (i) granulometria conjunta, (ii) limites de Atterberg (LL e LP), (iii) massa específica dos sólidos, (iv) compactação, (v) CBR, (vi) resistência à compressão simples, (vii) análise da imersão de corpos de prova em água, (viii) durabilidade por molhagem e secagem, (ix) permeabilidade e (x) aplicação da metodologia MCT (compactação Mini-MCV e perda de massa por imersão). A mistura que apresentou maior valor de CBR, com 60 % flotação + 40 % de concentração, foi identificada pelo sistema de classificação TRB, e classificada como A-4(1) e apresentou composição granulométrica compatível para utilização como material de sub-base conforme especificações do DNIT (2006). No entanto, possui um coeficiente de uniformidade entre 5 e 6, o que denota uma granulometria uniforme, refletindo negativamente no comportamento hidromecânico. Para aplicação como base de pavimentos, a mistura deverá ser estudada com um acréscimo de 8,5 % de cimento, porcentagem determinada por este trabalho, para atender à resistência mecânica média de 2,1 MPa, requerida para misturas de solo- cimento conforme ABCP (1980).

Texto completoSistemas de melhorias vêm sendo utilizado com uma maior freqüência nas últimas décadas com a finalidade de aumentar a competitividade no mercado. A intenção de focar o estudo em um sistema de melhorias baseado na avaliação de desempenho vai ao encontro de propor uma mensuração dos planos de ações deste sistema. Pois, realizar melhorias em um processo envolve não apenas conceitos e ferramentas, mas também a metodologia de mensuração para diagnosticar as ações adotadas durante a implantação do projeto. O estudo foi realizado na indústria CVI Refrigerantes Ltda, franqueada pela The Coca-Cola Company e Heineken Brasil, com fábrica em Santa Maria e Centros de Distribuição em Passo Fundo e Santa Cruz do Sul. Para implementação de um modelo de avaliação em um plano de melhorias que esta sendo proposto, utilizou-se o quarto passo do modelo proposto por Siluk (2007) Performance, caracterizado pelo processo de melhoria contínua, pessoal e organizacional. Com a finalidade de quantificar esta ferramenta empregou-se modelos de correlação e regressão linear - séries temporais, propondo uma modelagem do sistema de melhorias organizacional para dois atributos da qualidade em uma indústria de refrigerantes carbonatação e torque. A expectativa é que, as melhorias implementadas em cada área trará resultados para toda a companhia ou para as demais franqueadas do Sistema Coca Cola. Os principais resultados foram a obtenção de primeiro lugar no atributo de torque e segundo lugar no atributo de carbonatação no ranking Coca Cola Brasil.

Texto completoMine tailings are materials of low in situ densities and strengths, in general – often susceptible to liquefaction. In view of this, soil improvement methods such as Deep Soil Mixing can be alternatives for the stabilization of these materials. In this sense, based on DSM techniques, this research aims to analyze the mechanical behaviour of cemented gold mine tailings, comparing to its natural condition, evaluating factors that influence the stabilization (cement content, initial water content and type of water for preparing specimens). For this purpose, unconfined compressive tests, splitting tensile tests, ultrasonic pulse velocity tests and undrained triaxial (CIU) tests were used. The results showed that remoulded mine tailings samples presented low strength and liquefaction susceptibility under low confining pressures. In its turn, the tests with cemented gold tailings revealed that: increasing the cement content, decreasing initial water content and using water from the tailings pond (liquor) in moulding provided strength (qu and qt) and initial stiffness (G0) gains on the mixtures of gold mine tailings-Portland cement. In this regard, the variance analysis statistically demonstrated that all the factors chosen on the experiment were significant to the parameters assessed It is also showed that the cement content influence was much more pronounced than other factors. Furthermore, the stress-strain behaviour of the blends is typical of cemented materials under low confining pressures and undrained conditions – with negative pore-pressures build-up. In addition, it is demonstrated that the porosity/cement index controls the mechanical performance of gold tailings-Portland cement blends, considering the whole range of densities and cement contents studied – what broadens the applicability of such index. Finally, it was found a single relationship between tensile (qt) and compressive strength (qu) equal to 0.17, being independent of the porosity/cement ratio.

Texto completoThis dissertation describes metabolic engineering of cyanobacterium Synechococcus elongatus PCC7942 as a photosynthetic host for the conversion of CO2 into 2,3-butanediol. Current advances in pathway design, genetic tool development, and yield improvement are described (Chapter 1). A pathway for the synthesis of 2,3-butanediol is designed based on collective concepts of pathway strength, robustness, and irreversibility, and extensively tested through the generation of mutants (Chapter 2). This pathway is then optimized through modulation of translation by combinatorial mixing of ribosome binding sites (Chapter 3). Finally, photosynthetic productivity is investigated through expression of an exogenous pathway targeting every step between fixation and product (Chapter 4). All materials and methods are given separately for easy reference (Chapter 5).

Texto completoThe richness and diversity of forage species in the Campos Sulinos region may facilitate the inclusion of native species in breeding programs. Native grasses of the Paspalum genus show great variability which may contribute to the selection of adaptable genotypes to the various ecological conditions of tropical and subtropical regions. Within the genus, Paspalum notatum is a species with superiorly productive ecotypes compared to commercial cultivars, rendering this species a candidate for the release of new cultivars. The evaluation of bred plants submitted to different management practices, such as fertilization or consortium with legumes is fundamental to acquire knowledge about the productive features. The objective of the present work was to evaluate the productive potential of an intraspecific hybrid progeny of Paspalum notatum submitted to different nitrogen fertilization levels or intercropped with legumes, with the objective of being used in grazing systems or in the recovery of degraded natural pastures. The dry matter yield and tiller population density of Paspalum notatum genotypes respond positively to nitrogen fertilization levels. The 120 kg N ha-1year-1 fertilization level promotes the highest nitrogen utilization efficiency in Paspalum notatum. Genotypes B26, C22, C9 and Bagual are indicated for legume intercropped systems with temperate legumes. The dry matter production of intercropped systems between Paspalum notatum genotypes with white clover plus birdsfoot trefoil is similar to the production of systems fertilized with up to 240 kg N ha-1year-1, demonstrating the viability of the intercropped between these species.

Resumo: Este trabalho tem como objetivo primordial apresentar um método de integração do Balanced Scorecard - BSC como modelo Quality as a Business Strategy - QBS, composto por 15 tarefas, subdivididas em atividades para executá-Ias, relacionadas a propósito, visão sistêmica, mensuração do desempenho, sistema de informação, gestão estratégica, priorização e gestão de esforços de melhoria. A principal finalidade desse método é estabelecer um sistema abrangente de gerenciamento e de melhoria do desempenho global de uma organização. Os dois modelos que constituem a base conceitual do método possuem diversas congruências que podem ser mais bem exploradas em seu uso integrado, na medida em que definem melhoria contínua como parte da estratégia de negócios, propõem uma forma holística de avaliar a organização e alinham as iniciativas organizacionais com seu propósito e sua estratégia. O forte embasamento do QBS na teoria do "Saber Profundo" de William E. Deming provê o método de uma estrutura sólida, complementada pelo enfoque do BSC no alinhamento da organização à estratégia. O método foi aplicado em uma organização do setor público que se encontrava, no início desta pesquisa, em estágio incipiente de estruturação e gestão: a Agência de Inovação Inova Unicamp ? órgão vinculado à Reitoria da Universidade Estadual de Campinas. Discorreu-se sobre os principais pontos fortes, barreiras e dificuldades enfrentados na aplicação prática do método em uma organização pública. Resultados substanciais foram alcançados com a implementação do método
Abstract: The main objective of this dissertation is to present a management method which integrates Balanced Scorecard - BSC with the model Quality as a Business Strategy - QBS, composed by 15 tasks, deployed in specific activities, related to purpose, systems thinking, performance measurement, information systems, strategic management, prioritization and management of improvement efforts. The major aim of this method is to establish a comprehensive management System to improve organizational performance. The synergies of both models that form the conceptual framework of this method can be better explored through their integrated usage, since both define continuous improvement as a business strategy, incorporate a holistic approach to view and evaluate an organization and align organizational initiatives with its purpose and strategy. The strong foundation of QBS on William E. Deming's "System of Profound Knowledge", complemented with BSC's focus on aligning organization with its strategy, enhances the method's conceptual structure. This method was applied at Unicamp Agency for Innovation, a public sector organization, governmental organ from the State University of Campinas. The major strengths, barriers and difficulties faced during the implementation of a management method in a public organization were discussed in details. Considerable results were achieved with the implementation of this method

Texto completoChalk is a limestone formed by calcite, with up to 95% of calcium carbonate content. It can be found in Western Europe and it covers about 15% of the area of the United Kingdom. Many constructions and infrastructure works are carried out on chalk, and unpredictable situations still happen due to the lack of knowledge of its geotechnical behavior. Undisturbed, chalk is a weak rock that remains stable. However, when crushed, it breaks easily. These challenges, coupled with the abundance of this material in the UK, have led chalk to be studied in recent years for a better understanding of its characteristics and behavior. One of the ways of improving the chalk behavior is with the addition of Portland cement to the material, which is developed in this research. The chalk used in the testing was collected in St. Nicholas, Kent, UK, and characterised as CIRIA Grade A/B, low to medium density. The material was crushed in the laboratory until it became sandy silt, with D50 of 0.035 mm. The material was mixed with high initial strength Portland cement, at 3, 5 and 7% in relation to the dry soil mass The results of unconfined compression, traction by diametral compression and initial stiffness (G0) tests showed a gain of strength with the increase of cement content and specific dry unit weights in the studied samples. The strength data was analyzed as a function of the porosity by the volumetric content of cement (/Civ), showing the influence of the level of cementation and compaction in the strength of the mixture. The adjustment exponent of 0.28 in the cementing agent volume generated better determination coefficients in the results. There was an almost linear relationship between initial stiffness and unconfined compression strength. The stiffness versus time curves showed a logarithmic trend for the evolution of G0 with time in all samples. In the durability tests, the higher the dry unit weight and cement content of the sample, the lower the mass loss. The stiffness remained practically constant during the 12 cycles.

Texto completoThe recent research had as a main objective to understand how individuals with educational disabilities see and realize the movements in favor of inclusive education, as well as to identify what are their perspectives towards this inclusion, exploring still, inclusive processes in higher education. Therefore, we used as methodology strategy the analyses of life itineraries of three students with special educational needs. These individuals were chosen due to the fact of making possible the analysis of inclusive practices in fundamental education as much as in the university context. There were made semi structured interviews with the three investigated persons and the collected data was analyzed from the postulates of the social-historical theory and the studies about Vygotski`s defectology. Considering that no categories of analysis a priori, were determined, the collected data was grouped in an effort that aimed to identify the recurrent aspects, regarding the interviews that were going to meet the objectives outlined for the research. After that, the following categories were listed: recognition given by the individuals to their families; the obstacles and improvements in the inclusive practice; contributions of the individuals to qualify the inclusive practice in education and the inclusion in higher education. The three itineraries demonstrate there has to be done investment in the social interactions of disabled people in order to overcome the stereotypes carried by them. From the data analyzed, we could observe still that the prejudice, which originated from the lack of knowledge and contact with people in special needs, comes as one of the main impediments of the inclusion. In the same way, the inclusion in higher education revealed as a subject that needs to be incorporated to the guideline of studies and debates of the society and, mainly of the university institutions. To sum up, it is important to stand out that the individuals with special needs are open to the debate and to the construction of an inclusive society and that they have a lot to say and to contribute.

Texto completoThe soil properties commonly may not suit the project characteristics and requirements. It is presented, as alternative, the improvement technique of fibrous elements inclusion to the cemented and uncemented soil matrix. Moreover, although common, the behaviour of soil under cyclic loads is not completely known. In this sense, the study of the hydration behaviour and the cyclic shear response of fibre reinforced cemented mine tailings is the main objective of this research. Therefore, chemical shrinkage measurements, stiffness measurements during hydration and monotonic and cyclic simple shear tests were conducted on fibre reinforced and unreinforced cemented and uncemented mine tailings. The tailings, produced from gold mining, are classified as a sandy silt with traces of clay and were cemented with different amounts of Portland cement, ranging from 0% to 10% by dry weigh of soil, and reinforced with 0% and 0.5% by dry weigh of solids of polypropylene fibers 50mm long and 0.1mm thick, equivalent to an aspect ratio of 500. The results showed fibres did not affect the hydration process of cemented mine tailings mixtures, which presents logarithmic attenuation of chemical shrinkage over time. The greater the water / cement ratio, the higher the level of chemical shrinkage. The inclusion of fibers to cemented mine tailings, likewise, did not affect the evolution of initial stiffness values, that raise logarithmic over time and increase with the increase of the cementation level. Under monotonic shear conditions, the addition of fibers confers hardening behaviour to the uncemented and cemented materials. Under shear strain controlled cyclic conditions, fibres did not affect the shear response of uncemented samples and increased shear stress values of cemented samples after successive load cycles. Under shear stress controlled cyclic conditions, the fibres addition to the uncemented mixtures increased the resistance to load cycles and to the cemented mixtures increased levels of shearing strain. The agreement of the same strength envelopes to both monotonic and cyclic stress paths, under different cyclic loading conditions, allows the use of the same strength parameters of mixtures analyzed under different loading conditions.

Texto completoArgilas dispersivas, também conhecidas como solos altamente erosivos, são dispersas na presença de água relativamente pura, tal como a causada por precipitações. Esse fenômeno é gerado pela ação que à água intersticial presente no solo ter uma maior concentração de cátions do que a água pura de chuva. A adição de cal nestes solos, é uma técnica de melhoramento das características físicas nas argilas dispersivas, assim também como suas propriedades mecânicas. A presente pesquisa tem por objetivo quantificar a influência isolada de cada variável; quantidade de cal, porosidade e tempo de cura, sobre a resistência não confinada de um solo dispersivo tratado com cal e permitir avaliação da transformação para um estado não-dispersivo. Esta dissertação visa a compreensão dos parâmetros-chave da mistura de argila dispersiva com adição de cal para o controle das resistências à compressão simples (qu) e de tração (qt). Assim, mostra-se que a relação vazios/cal é um parâmetro adequado para avaliar estas resistências não confinadas. Em consequência, verificou-se uma única relação qt=qu igual a 0,136, sendo independente da relação vazios/cal e o tempo de cura. Além disso, verificou-se que a metodologia para previsão de Envoltórias de Mohr-Coulomb é adequada para a determinação dos parâmetros de resistência. Finalmente, desde um enfoque ambiental através da ferramenta de avaliação do ciclo de vida (ACV) foram avaliadas todas as misturas em função ao custo energético envolvido (energia incorporada). Esta avaliação foi realizada através de um comparativo em Mega Joules por metro cúbico de mistura [MJ=m3].

Texto completoIn this work, we develop two major research routes related to molten carbonates. The first one is the molten carbonate fuel cell optimization, with two approaches: (i) cathode lifetime improvement through ultra-thin layers of metal oxides deposited by atomic layer deposition; (ii) Li-K and Li-Na electrolyte modification by Cs or Rb additions. The second one is dedicated to CO2 valorization through its electrochemical reduction in molten carbonate electrolytes, where we analyze CO2 reduction by means of chronopotentiometry and chronoamperometry. Finally, in order to test some of the component modifications described in the two first parts, we installed and adapted a single-cell setup coupled to gas chromatography. We obtained some significant results in all the approaches; concerning point (i), we found that TiO2 and CeO2 are suitable for cathode corrosion protection without affecting the electrochemical properties of the electrode and reducing almost by half the dissolution of Ni. The results obtained from point (ii) are also fruitful, since we established a method for comparing two different electrolytes and obtained the diffusion coefficients of the superoxides and carbon dioxide. We also compared the performance of the state-of-the-art NiO cathode in Cs and Rb modified electrolytes. From these studies, we found that Cs addition improves significantly the CO2 diffusion coefficient and reduces the charge transfer and total resistance at the electrode, being a promising additive. Regarding CO2 reduction, after all the tests performed, we found that the reaction involves adsorbed and instable species and occurs in two one-electron steps or in two-electron unique step; thus, it follows most probably a mechanism of simultaneous reduction of the adsorbed and dissolved species. Finally, we performed the first MCFC single-cell tests in our laboratory obtaining an acceptable cell performance and output power. However, small improvements are still necessary to be able to test MCFC modified components

Resumo: Diversos são os recortes pelos quais se tem analisado as questões da inclusão da pessoa com deficiência, sejam nas pesquisas desenvolvidas nos foros acadêmicos, ou nos debates sócio-político-econômicos. É nítida, no âmbito histórico, uma rápida evolução conceitual nas diversas publicações acadêmicas e políticas em que se apresenta o tema, principalmente nas últimas quatro décadas, o que tem proporcionado um redirecionamento no olhar e práticas direcionadas a inclusão desta população. No entanto, ao destacarmos as políticas expressas na legislação, confrontadas com as práticas, planejamento e articulações desenvolvidas nos municípios, nos defrontamos com uma realidade que expõe a desarticulação entre essas atividades, e principalmente, a quase completa ausência de instrumentalidades que possibilitem aferir sua eficácia. Se por um lado, as agências formadoras tentam desenvolver em seus graduandos conceitos que possibilitem uma sociedade inclusiva e que contemplem com um novo olhar a pessoa com deficiência, de outro lado, observamos o descompasso entre a intenção e a prática, e principalmente, entre os setores que planejam e os que gerem os processos inclusivos. Isto resulta em processos não racionalizados, com sobreposição de tarefas, de custeio ou de atendimentos, retrabalho, falta de atendimento pela inferência de que alguma atividade seja de outro setor, além de um conjunto de informações dispersas ou desconexas, e por fim, ausência de indicadores confiáveis que propiciem validação de resultados. Desta percepção decorre a necessidade de modelos de integração destes conceitos (oriundos da pesquisa e ciência) e práticas (presentes nos ambientes sociais) em uma ação que apresente sincronia e alinhamento com um ponto de convergência comum (as necessidades humanas), e que possibilitem rastrear a eficácia dos resultados das políticas públicas. O presente trabalho evoca o uso da metodologia de modelagem e desenho de processos orientadas a valor, aliada a uma abordagem de resolução de problemas complexos, como alternativa para o estabelecimento, mapeamento e verificação de indicadores de gestão de processos inclusivos, e monitoramento, validação e rastreabilidade de resultados das ações voltadas à inclusão. Concluímos, pela otimização de processos e resultados obtidos pela aplicação desta metodologia, ela se demonstrou útil para certificar municípios, entidades ou quaisquer outros níveis de recortes estruturais, aferindo e validando processos de inclusão, além de fornecer indicadores para correção e planificação das ações de formação ou indicação de áreas de carência em pesquisa e desenvolvimento, contribuindo para a eficácia, e não somente eficiência, das atividades desenvolvidas no sentido da inclusão da pessoa com deficiência
Abstract: There are several clippings by which it has been analyzed the issues of inclusion of people with disabilities in research are developed in academic forums, or in the socio- political and economic debates. It is clear, in the historical context, a quick conceptual evolution in several academic publications and policies which presents the theme, especially in the last four decades, which has resulted in a redirect gaze and practices aimed at inclusion of this population. However, when we cut the policy expressed in legislation, confronted with the practical, engineering and joints developed in the municipalities, faced with a reality that exposes the lack of connection between these activities and especially the almost complete absence of instrumentalities that enable measuring its effectiveness. On one hand, the training agencies try to develop concepts that enable its graduates an inclusive society and contemplating a new look with the disabled person, on the other hand, we observe the gap between intention and practice, and especially among sectors planning and managing the inclusive processes, resulting in not streamlined processes, with overlapping tasks, or calls costing, rework, lack of care by the inference that some activity is of another sector, plus a set of Scattered or disconnected information, or lack of reliable indicators that provide validation of results . From this perception stems the urgent need of models of integration of these concepts (derived from the research and science) and practical (present in social settings) in synchrony to submit an action and alignment to a common point of convergence (human needs), and enabling to track the effectiveness of the results of public policy. This work evokes the use of the value-oriented methodology for modeling and designing processes, combined with an approach of solving complex problems, as an alternative to the establishment, mapping and verification of management indicators of inclusive processes and monitoring, validation and traceability of results of actions aimed at inclusion. We conclude that such a methodology, if applied, could make municipalities, entities or other levels of structural clippings, assessing and validating processes of inclusion and provide indicators to correction and planning of training activities or indication of areas of need in research and development contributing to the effectiveness, not just efficiency, of the activities developed for the inclusion of people with disabilities

Texto completoThe performance measurement implementation fails in many companies because of lack of information technology (IT) support. Hence it is obvious that IT is one of the critical success factors for performance measurement implementation. The successful implementation of performance measurement depends less on selecting the right measures and more on the way the measures are implemented and used by the people in the business. The data collection, analysis and reporting should be automated as much as possible to save time and effort as well as to provide consistency. Software from PMS is defined as an ideal the better designed (technical factors) and meet people (personal factors) of the organization. The successful deployment of an PMS is related to the ability of organizations to react to changes and manage the use of automated performance measurement, exploiting the latest technology. This thesis aims to improve software performance measurement based on user satisfaction in a business of pulp and paper. The quasi-experiment showed that the end user participating in the full development of PMS, since its design and in all stages of validation or the definition of improvement, they realize the benefits of deployment, and can understand the logic of the management model the company, its tools and concepts. The results of research in this thesis, we hope to benefit many users who have or are planning to implement performance measurement software.
A implantação de Sistemas de Medição de Desempenho (SMD) muitas vezes falha por causa de falta ou uso incorreto da Tecnologia de Informação (TI). O sucesso na implantação desse tipo de sistema depende tanto da seleção correta das medidas de desempenho quanto do modo como elas serão implantadas e utilizadas na empresa. Por isso, a coleta de dados, a análise e a informação devem ser automatizadas o máximo possível para economizar tempo e esforço como também para prover consistência. Um software de SMD é definido como ideal quanto melhor for projetado (fatores técnicos) e quanto melhor satisfazer as pessoas (fatores pessoais) da organização. O sucesso na implantação de um SMD está relacionado à capacidade das organizações para reagir a mudanças e a gerenciar o uso de sistemas automatizados de medição de desempenho, que exploram a tecnologia mais recente. Esta dissertação tem por objetivo melhorar o software de medição de desempenho com base na satisfação do usuário em uma empresa de celulose e papel. O quase-experimento realizado demonstrou que o usuário final participa do desenvolvimento integral do SMD, desde o seu projeto e em todas as etapas de validação ou na definição de melhorias, percebe os benefícios da implantação, e também consegue compreender a lógica, as ferramentas e os conceitos do modelo de gestão da empresa. Os resultados da investigação apresentada nesta tese deve beneficiar muitos usuários que têm ou estão planejando implementar um software de medição de desempenho.

Texto completoThe competitiveness of an organization and consequently its prosperity before competitive markets, depends widely on the capacity for innovation and improvement of its products/services and processes. The pursuit for better manufacturing standards and services provided to customers, in addition to the applications of new management techniques, continuous improvement, optimization and decision-making, have attracted attention of organizations. The human creative effort should propose approaches of competitive basis, combining tools and techniques, known or not, in order to improve their performance. Thus, the objective of this thesis was to propose an analytical structure integrating sequentially the process of continuous improvement DMAIC of Six Sigma and the multi-criteria analysis method for decision making Analytic Hierarchy Process (AHP), in order to apply in real cases in beverage industries. At first, through a literature search, it was proposed a general structure, called Analytical Structure DMAIC/AHP, involving the above theories. In addition, with a case study aid, it was proposed a detailed structure attempting to improve the operation of physical distribution for beverages in a company in the city of Ribeirão Preto. The focus was also on the opportunity to gain greater knowledge of the process under study and improve the foundation for decision making. The application of analytical structure was divided into three phases: phase 1 - definitions for the improvement project; phase 2 - implementation of the improvement process itself; and phase 3 (called metaphase) - responsible for monitoring/following the activities of the project. The application in a real case allowed the proposal of activities and tools for the understanding and improvement of the process, as well as possibilities for more alternatives to problems encountered; provided foundation for decision making at the time of implementing the improvements and presented tools for maintenance and control of changes proposed in the project. An obvious gain from the junction of the theories was that there was a mutual aid between them. Thus, the process of continuous improvement DMAIC, through its detailed stages of knowledge of processes and causes of problems could robustly base the definition of the hierarchical model of AHP, since the overall objective to be attained, passing through the decision criteria, until they get to the alternatives of decisions proposed for the process under study. On the other hand, as the DMAIC does not present an attractive method of decision-making, AHP could assist in multi-criteria decision making more organized, consistent and assertive.

Texto completoBrazil is the largest sweet orange producer in the world. The history of the Brazilian citrus industry is marked by a series of diseases caused by different etiologic agents. Among the diseases affecting the culture, those caused by bacteria are the ones that have caused more significant losses, especially the citrus canker caused by Xanthomonas citri subsp. citri, and huanglongbing (HLB) associated with three \"Candidatus Liberibacter\" bacteria species. Due to the absence of genetic resistance to these diseases in commercial sweet orange cultivars, the genetic transformation is a promising alternative to produce resistant plants. One of the strategies to produce transgenic resistant plants to bacteria is the use of genes that code for antimicrobial peptides, such as D4E1, a antimicrobial synthetic peptide, which has shown efficient results controlling diseases caused by bacteria and fungi in several crops, through in vitro and in vivo experiments. The aim of this study was to produce \'Hamlin\', \'Pêra\' and \'Valencia\' sweet orange transgenic plants, via Agrobacterium tumefaciens, expressing the D4E1 gene driven by the constitutive promoter Cauliflower mosaic virus (CaMV35S) or Arabidopsis thaliana phloem protein 2 (AtPP2), a promoter preferentially expressed in the phloem. It was possible to regenerate 13 \'Hamlin\' transgenic lines, 10 \'Pêra\' transgenic lines and 8 \'Valencia\' transgenic lines bearing the gene construct CaMV35S/D4E1, whereas 19 \'Hamlin\' transgenic lines, 6 \'Pêra\' transgenic lines and 15 \'Valencia\' transgenic lines bearing the AtPP2/D4E1 gene construct were regenerated. The transgenic plants had one to three T-DNA insertion events in the genome. The transgene expression levels in transgenic plants for D4E1 gene driven by the phloem preferential promoter were lower than the transgenic expression levels of the transgene driven by the constitutive promoter. Transgene expression levels results may allow the selection of those plants with higher expression levels of each genetic construct for future multiplication and evaluation for citrus canker and HLB resistance.

Texto completoThis thesis is part of a continuing project at the Naval Postgraduate School attempting to validate the cost effectiveness of the Aircraft Engine Component Improvement Program. It focuses on the costs and benefits derived from Power Plant Changes 159 which improved High Pressure Turbine, Second Stage blades on the Harrier (AV-8B) aircraft's Rolls-Royce Pegasus (F402-RR-F406A) engine. Because sufficient failure rate date for the improved blades was not available, the analysis considers a range of costs/benefits based on two different projected blade reliabilities. The improvement to the High Pressure Turbine, Second Stage blades was found to be cost-effective from both a financial break-even point, in that the cost to produce the improvement will be recovered by the end of 1996 for the full range of blade reliabilities and from a Net Present Value analysis which shows that this improvement will save the Department of the Navy between $17,192,827 and $38,639,494 (in 1992 dollars) over the projected life cycle of the engine

Small companies face barriers to either implement or enhance their software testing processes due to the lack of experts in testing, the lack of resources and difficulties to adapt testing-related maturity models to a particular context. The goal of this research is devising a strategy that can be applied by software companies to the definition of testing processes, or even to the enhancement of the current company s process. The strategy for the definition of testing processes has been built upon the results of a case study of a small software development company. In such case study, we have characterized the company s current testing process and, based on it, we have devised a new process that relies both on the TMMi reference model and on the results of a survey that has gathered the opinion of professionals in software testing. The three main contributions of this research are: (i) a reduced test process model as a result of the mentioned survey; (ii) a newly devised testing process for the case company; and (iii) a strategy for the definition of testing processes devised from the case study, which is based on the TMMi reference model and on the opinion of software testing professionals. The sequence of steps performed in the case study enabled us to establish a testing process that takes into consideration the TMMi model and other company s particularities, thus resulting in a process whose focus is on quality. Performing such steps enables the company to evaluate and enhance its testing process whenever required.
Pequenas empresas encontram algumas barreiras para implementar ou melhorar seus processos de teste devido à falta de profissionais especializados em teste, falta de recursos e também devido à dificuldade em adaptar modelos de maturidade em teste para o contexto específico da empresa. O objetivo deste trabalho é apresentar uma estratégia para que as empresas possam definir um processo de teste, ou melhorar o processo de teste existente. A estratégia para elaboração de um processo de teste para pequenas empresas foi extraída a partir da realização de um estudo prático em uma pequena empresa desenvolvedora de software. Nesse estudo estabeleceu-se como base o processo de teste existente na empresa e definiu-se um novo processo de teste, tendo como referência o TMMi e um survey, que coletou a opinião de profissionais que atuam na área de teste. Os três resultados obtidos neste trabalho são: (i) O modelo de um processo reduzido, resultante do survey; (ii) um novo processo de teste que foi proposto para a empresa; e (iii) uma estratégia para elaboração de processo de teste extraída de um estudo prático, com base no TMMi e na opinião de profissionais de teste. A sequência de passos que foi realizada no estudo prático permitiu chegar a uma proposta de processo de teste que leva em consideração o TMMi, sendo portanto, uma proposta de processo com foco em qualidade. A generalização dos passos executados resultam em uma estratégia que pode ser aplicada por empresas para avaliar e melhorar seu processo de teste sempre que necessário.

Como parte de uma política de institucionalização da avaliação, o Ministério da Saúde desenvolveu a proposta de “Avaliação para a Melhoria da Qualidade da Estratégia Saúde da Família - AMQ”, que se apresenta como uma metodologia de gestão interna dos serviços. A proposta caracteriza-se, como um processo participativo, que inclui os diversos atores envolvidos com a intervenção e com direcionamento para a utilização dos resultados. Este estudo analisa a proposta AMQ, buscando identificar elementos que possam favorecer a utilização dos resultados. Neste sentido, analisou-se a evolução histórica das práticas avaliativas e identificou-se na proposta de avaliadores de quarta geração e na discussão sobre meta-avaliação significativa atenção com a finalidade e utilidade da avaliação, numa perspectiva de aumento do valor de uso no âmbito dos processos de tomada de decisões. A avaliação com foco na utilização foi identificada como uma das principais abordagens que valorizam estes aspectos. Desta forma, realizou-se uma aproximação entre a avaliação com foco na utilização e a proposta AMQ, procurando reconhecer nesta última o nível de valorização existente da abordagem avaliativa com foco na utilização e o uso potencial dos seus elementos orientadores.

Texto completoHLB is currently considered the main disease affecting citrus plants. Given this factor, research for cultivars resistant to this disease is needed. Genetic transformation via Agrobacterium with the use of model plants has been an alternative for checking the gene function in response to pathogens, because these model plants have as characteristic a short life cycle and high power of regeneration. Therefore, the aim of this work was to produce transgenic plants, via Agrobacterium tumefaciens, of Micro-Tom tomato (Solanum lycopersicum L.), and sweet orange, with the genes encoding the PR-8 and CDR-1 proteins isolated from Citrus sinensis. The cotyledons from in vitro germinated Micro-Tom tomato seeds were used as explants source for genetic transformation experiments with PR-8 and CDR-1 genes. These explants were subcultured until the appearance of regenerating shoots and after transgenic plants, which were acclimatized and taken to a greenhouse. The transgenic plants were confirmed by PCR and the number of gene insertions by Southern blot. The plants were grown until T1 generation was obtained. Simultaneously genetic transformation experiments were performed with epicotyl segments from \'Hamlin\' sweet orange seeds germinated in vitro with CDR-1 gene in order to obtain transgenic plants and their characterization. Simultaneously, the standard curve construction was performed by qPCR analysis for identification of Pseudomonas syringae pv. tomato. Thirteen transgenic plants of Micro-Tom tomato with PR-8 gene and three with CDR-1 gene were obtained. The transformation efficiencies were around 0,38 to 1,98%. Three transgenic plants of Micro-Tom tomato with PR-8 gene were characterized by southern blot, and the number of inserts ranged from 1 to 3. Nineteen transgenic \'Hamlin\' sweet orange plants with CDR-1 gene were obtained through genetic transformation experiments, and the transformation efficiency was 2,06 to 5,96%. One plant was characterized, by Southern blot and has one DNA copy number in the plant genome.
