Viabilidad técnica para la explotación y separación isotópica de Li y prospectiva en el mercado de baterías de ION-7Li y de 6Li como material base de diseño en reactores de fusión nuclear

En claro alineamiento con estrategias de sostenibilidad en el uso de recursos naturales en un escenario constante de aumento de la demanda energética mundial, el desarrollo de la tecnología energética en la Historia de la Especie Humana muestra un vector de evolución permanente desde su origen en el sentido del desarrollo y uso de nuevas fuentes energéticas con la explotación de recursos naturales de manera más eficiente: soluciones energéticas con aumento de la densidad energética (exoenergía de proceso por unidad de masa de recurso natural). Así el cambio de escala en la demanda de explotación del Litio como recurso natural se viene presentando en la última década ligada al desarrollo del mercado de las baterías "ion-Litio" y los requisitos de combustible (Deuterio y Litio) en el camino de la fusión nuclear como opción energética próxima. El análisis anticipado de las demandas sinérgicas a escala de ambos mercados aparece de enorme interés prospectivo en sus aspectos técnicos: (1) tecnologías de base para la extracción mineral y de agua marina y (2) su enriquecimiento isotópico (de interés sinérgico; 7Li para baterías eficientes ion-litio; 6Li como regenerador de tritio en ciclo de combustible en fusión nuclear) a la vez que en sus aspectos económicos. Este Proyecto realiza: (1) un ejercicio de análisis prospectivo de la demanda y de mercado para el enriquecimiento 6Li/7Li para las próximas décadas, (2) se califican los desarrollos tecnológicos específicos que van a poder permitir la producción a escala conforme a la demanda; (3) se selecciona y califica una técnica [de centrifugación / termo-difusión/ destilación combinada] como opción tecnológicamente viable para la producción a escala de formas litiadas; (4) se propone un diseño conceptual de planta de producción y finalmente (5) propone un estudio de viabilidad para la demostración de proceso y construcción de dicha planta de demostración de la nueva capacidad tecnológica. ABSTRACT Clearly aligned with sustainability strategies under growing world energy demand in the use of natural resources the development of energy technology in the history of the human species shows a vector of ongoing evolution from its origin in the sense of the development and use of new energy sources with the exploitation of natural resources in a more efficient manner. The change of scale in the demand for exploitation of Lithium as a natural resource appears during the last decade as bound to the deployment of "lithium-ion" batteries market and to the Nuclear Fusion fuels (deuterium and lithium) supply scaled demands. The prospective analysis of demands to scale in both markets appears in scene with huge prospective interest in its technical aspects: (1) base technologies for mineral and water marine extraction (2) its isotopic enrichment (synergistic interests; 7Li efficient battery Li-ion; 6Li as fusion nuclear fuel breeder (tritium) as well as in its economic aspects. This Project: (1) propose a prospective analysis exercise of the synergistic supply demand for coming decades for the enrichment of 6Li and 7Li, (2) qualifies specific technological developments ongoing to respond to supply demand; (3) select and qualifies an appropriate technique [combined centrifugation/thermo-diffusion/distillation] as technologically viable option for lithiated forms scaled-production; (4) proposes a conceptual design of production plant based on the technique and finally (5) proposes a feasibility study for the process demonstration and construction of this new technological capability Demonstration Plant.

Estudio histórico del convento agustino extramuros de Madrigal de las Altas Torres y la intervención clasicista del arquitecto Juan del Ribero Rada

Esta tesis estudia y analiza el que fue importante convento de los agustinos calzados, extramuros de la villa de Madrigal de la Altas Torres. El conjunto que en su día fue llamado el “Escorial de Castilla”, donde murió fray Luis de León en 1591, con cátedras de teología y filosofía y casa de capítulos provinciales, ha visto languidecer sus fábricas en paralelo al declive de Castilla y al de la propia villa de Madrigal, hasta que (al igual que en otros muchos casos) los decretos de supresión y desamortización en el siglo XIX, cerraron definitivamente sus puertas como convento y las abrieron a la destrucción y a la ruina que hoy presenta. En mi condición de arquitecto e historiador he pretendido seguir una metodología que aúne tanto los aspectos históricos del edificio, que permitan un mayor conocimiento del mismo, como otros aspectos estrictamente arquitectónicos en su doble vertiente compositiva y constructiva-tipológica, dentro del marco de la arquitectura clasicista en la que de forma clara se define el convento. Estos campos se completan con los levantamientos planimétricos del edificio y con su modelización, que tratan de analizar la evolución del convento a través de su tiempo, reinterpretando el volumen que pudo tener en el siglo XVI y XVII (el imaginado por el tracista). Se trata pues de una metodología que quiere ser integradora de disciplinas que frecuentemente discurren por vías separadas, pero que tienen el objetivo común señalado. En el primer tomo, el estudio histórico del convento recoge los aspectos cronológicos del edificio, localizados en una sistemática y razonable búsqueda en los archivos y fuentes documentales, así como las relaciones de poder y de patronazgo que a distintas escalas se establecen entre el convento y la Corte (especialmente durante los siglos XV y XVI), y otro tipo de conexiones e influencias (menores pero no por ello menos importantes) entre los frailes de Madrigal y la orden agustina calzada a la que pertenecen, o entre el convento y su territorio, identificado principalmente con la villa de Madrigal. Es en definitiva el conocimiento de quiénes, (frailes, arquitectos, maestros, artistas etc. ), cómo y cuándo han intervenido en la ideación, ejecución, sostenimiento (e incluso destrucción) del edificio, dentro de los avatares sociopolíticos y administrativos de cada periodo. No podemos olvidar por otra parte, los aspectos económicos, que como veremos juegan un papel fundamental en la propia edificación del convento, cuyas fases constructivas se corresponden con aportaciones económicas extraordinarias, emanadas principalmente de la enorme fortuna personal de D. Gaspar de Quiroga, arzobispo de Toledo e Inquisidor General con Felipe II. El análisis del edificio se centra principalmente en su fase como convento de Agustinos, a partir de 1528, cuando las monjas agustinas que lo fundaron y habitaron se trasladan al antiguo palacio de Juan II, que reciben de Carlos I, y se lo ceden a los frailes por mediación de Santo Tomás de Villanueva, y su final tras las desamortizaciones decimonónicas. El segundo tomo recoge la descripción del edificio y su evolución en el tiempo, con las limitaciones que supone la pérdida actual de la mayor parte de sus muros. Se exponen también en este capítulo algunos de los aspectos constructivos del edificio, sus medidas y proporciones, que de alguna manera nos introducen en el capítulo de la arquitectura clasicista. Se estudia la arquitectura del convento en esta etapa, que abarca un periodo comprendido entre 1585 y 1645, por ser el momento en que se construye la práctica totalidad del mismo mediante los recursos y el patronazgo del arzobispo toledano. Tanto la traza del convento como la de la iglesia pertenecen al momento de mayor énfasis y dinamismo del clasicismo vallisoletano, representado por la figura de Juan del Ribero Rada, que interviene en ambos proyectos, siendo de especial interés el descubrimiento de que éste arquitecto es también el autor de la traza conventual, tal como se pone de manifiesto en el concurso de fray Luis de León de 1590, ampliándose el conocimiento de su obra arquitectónica. En relación con este análisis de la arquitectura clasicista de Juan de Ribero en Madrigal, se ha realizado un levantamiento planimétrico exhaustivo, que por sí mismo compone una parte substancial de esta tesis. Este levantamiento nos ha permitido dar un paso más, procediendo a la “reconstrucción” idealizada de sus volúmenes, tal como pudo ser concebida por el tracista y por el propio Quiroga, basándonos en los datos sobre el edificio que nos aportan tanto sus restos, como las diversas fuentes documentales. Ante un edificio excepcional y actualmente destruido casi en su totalidad 1, se debe entender este trabajo como parte de un proceso de recuperación de nuestra memoria histórica colectiva, entendiendo que el conocimiento de un edificio va más allá de la mera acumulación de datos.

Cobrança pelo uso da água e escassez de recursos hídricos: proposta de modelo de cobrança e aplicação na bacia do rio Atibaia

No Brasil, a Política Nacional de Recursos Hídricos apresenta a cobrança pelo uso da água como um instrumento de gestão de recursos hídricos de caráter econômico. Considerando esse caráter, a cobrança deve ter como objetivos: racionalizar o uso do recurso baseado na sua escassez; reconhecer a água como um bem de valor econômico, refletindo os custos ambientais advindos de sua utilização; e diminuir os conflitos entre os usos, induzindo uma alocação que considere o gerenciamento da demanda e as prioridades da sociedade. Além dessas metas, como instrumento de gestão de uma política que lista como primeiro objetivo \"assegurar à atual e às futuras gerações a necessária disponibilidade de água, em padrões de qualidade adequados aos respectivos usos\", a cobrança deve ser implementada de maneira que o agente usuário direcione seu comportamento no sentido da sustentabilidade ambiental. Mediante esses fundamentos, o que se pretende desenvolver neste trabalho é a aplicação de um modelo de cobrança sobre o uso da água que considera como princípio base a manutenção da qualidade ambiental medida pela adequada gestão da escassez de água e, compondo a busca dessa qualidade, a racionalização econômica e a viabilização financeira. Essa predominância do ambiente sobre aspectos econômicos vem no sentido de desqualificar argumentos segundo os quais, os impactos advindos dos usos da água serão corrigidos indefinidamente mediante investimentos financeiros em infra estrutura. Admitir que o desenvolvimento tem esse poder é supor equivocadamente que o meio econômico é limitante do meio ambiente e não o contrário. Esta constatação mostra qual é o problema da maioria das propostas de cobrança que valoram a água baseadas em custos de tratamento de resíduos e de obras hidráulicas. Por mais elaborados que sejam essas fórmulas de cobrança, chegando a ponto de se conseguir que fique mais caro, mediante um padrão ambiental corretamente definido, captar água ou lançar poluentes do que racionalizar usos, o preço da água não pode estar baseado em fatores cuja \"sustentabilidade\" pode acabar no curto prazo, dependendo do ritmo de crescimento econômico. A sustentabilidade dos recursos hídricos só será base da cobrança pelo uso da água se o valor cobrado for dificultando esse uso à medida que os recursos tornarem se escassos, e não quando os custos de medidas mitigadoras dessa escassez se tornarem muito elevados. Portanto, o modelo de cobrança proposto neste trabalho procura garantir que o agente econômico que está exaurindo o meio ambiente não possa ter capacidade de pagar por essa degradação, ajudando efetivamente a política de outorga do direito de uso da água na observância da capacidade de suporte do meio.

Real time optimization in chemical process: evaluation of strategies, improvements and industrial application.

The increasing economic competition drives the industry to implement tools that improve their processes efficiencies. The process automation is one of these tools, and the Real Time Optimization (RTO) is an automation methodology that considers economic aspects to update the process control in accordance with market prices and disturbances. Basically, RTO uses a steady-state phenomenological model to predict the process behavior, and then, optimizes an economic objective function subject to this model. Although largely implemented in industry, there is not a general agreement about the benefits of implementing RTO due to some limitations discussed in the present work: structural plant/model mismatch, identifiability issues and low frequency of set points update. Some alternative RTO approaches have been proposed in literature to handle the problem of structural plant/model mismatch. However, there is not a sensible comparison evaluating the scope and limitations of these RTO approaches under different aspects. For this reason, the classical two-step method is compared to more recently derivative-based methods (Modifier Adaptation, Integrated System Optimization and Parameter estimation, and Sufficient Conditions of Feasibility and Optimality) using a Monte Carlo methodology. The results of this comparison show that the classical RTO method is consistent, providing a model flexible enough to represent the process topology, a parameter estimation method appropriate to handle measurement noise characteristics and a method to improve the sample information quality. At each iteration, the RTO methodology updates some key parameter of the model, where it is possible to observe identifiability issues caused by lack of measurements and measurement noise, resulting in bad prediction ability. Therefore, four different parameter estimation approaches (Rotational Discrimination, Automatic Selection and Parameter estimation, Reparametrization via Differential Geometry and classical nonlinear Least Square) are evaluated with respect to their prediction accuracy, robustness and speed. The results show that the Rotational Discrimination method is the most suitable to be implemented in a RTO framework, since it requires less a priori information, it is simple to be implemented and avoid the overfitting caused by the Least Square method. The third RTO drawback discussed in the present thesis is the low frequency of set points update, this problem increases the period in which the process operates at suboptimum conditions. An alternative to handle this problem is proposed in this thesis, by integrating the classic RTO and Self-Optimizing control (SOC) using a new Model Predictive Control strategy. The new approach demonstrates that it is possible to reduce the problem of low frequency of set points updates, improving the economic performance. Finally, the practical aspects of the RTO implementation are carried out in an industrial case study, a Vapor Recompression Distillation (VRD) process located in Paulínea refinery from Petrobras. The conclusions of this study suggest that the model parameters are successfully estimated by the Rotational Discrimination method; the RTO is able to improve the process profit in about 3%, equivalent to 2 million dollars per year; and the integration of SOC and RTO may be an interesting control alternative for the VRD process.

Cultura e desenvolvimento: o caso de São Tomé e Príncipe

A questão que nos propusemos analisar consiste em perceber como é que a cultura pode ser um fator de desenvolvimento e em que moldes se tem processado. Em primeiro lugar, procuraremos definir o conceito de cultura, tendo em conta as diferentes aceções que tem adquirido ao longo do tempo, para estabelecer o que é que hoje quer dizer “cultura”. No fundo, abordar de que maneira a área da cultura se interliga com outros domínios, tais como os direitos humanos, a educação, a economia, o ambiente. Também procurar debater de que modo estas áreas são fundamentais para a compreensão da noção atual de cultura e como interferem na questão do desenvolvimento. Além disso, abordaremos o papel fundamental das indústrias culturais e criativas para a compreensão do que aqui está em causa. Deste modo, daremos resposta a questões como a forma de a cultura poder ser um fator de criação de emprego, qualificação e formação e como pode ser um impulso à economia. Ao considerar que a cultura tem um caráter pragmático, lançaremos um olhar sobre a realidade de São Tomé e Príncipe, de que analisaremos os principais espaços de criatividade, as principais questões que se conjugam com o fator cultural bem como o papel que lhe é atribuído enquanto um elemento a ter em conta nas políticas públicas. Em suma, pretendemos perceber o que ainda é preciso ser feito, procurando aliar um dos pontos que constituem a chave da cultura em STP – a tradição – às exigências das novas abordagens no setor cultural.

Pesca artesanal entre mudanças socioambientais: estudo de caso na APA Bonfim-Guaraíra/RN-Brasil

Artisanal fishing is one of the important economic activities of Rio Grande do Norte (RN), becoming the main form of survival and income for many families. The southern coast of RN has strong fishing tradition, both in exploitation of fish as in the collection of mollusks on the banks of Guaraíra Lagoon (APA Bonfim-Guaraíra). In recent years, fishing communities have become more vulnerable to outside influences, since the socio-economic and environmental changes are exposed. These changes require adjustments to the fishermen to different environmental conditions, as the social and natural systems are driven by reorganization and upgrading processes. The living conditions in fishing communities are objective and necessary in different ways, according to a selection that is cultural, so adaptable. This study has the general objective to analyze the main environmental changes in fishing communities, based on the understanding of fishermen and mollusk fisherwomen about this problem. The specific objectives searched to: describe the socioeconomic profile, prospects and difficulties of fishermen and mollusk fisherwomen; investigate the major social and environmental changes in the fishing communities of Patané and Camocim (Arez/RN). The methodology was qualitative-quantitative with the techniques of observation in the field and open and semistructured interviews applied to representatives of Cologne fishing, fishermen and mollusk fisherwomen. Between the months of January to July 2014 were applied semistructured interviews with 41 interlocutors in Patané and 23 of Camocim; totaling 64 people. The results indicated that the interlocutors are aged 40 to 60 years; have only completed elementary school level; are married and have children; survive on less than a minimum wage income and they are not receiving employment insurance. The case study also revealed that the socioeconomic and environmental problems reflected in changes in reproduction, organization and social division of labor, which generates adaptive changes of families to external influences, resulting directly from other economic activities and market pressure and indirectly from tourism. Therefore, adaptations to changes scenario presented as favorable to economic aspects and unfavorable to the social and environmental aspects. In short, the fishery develops on technical, bureaucratic and financial obstacles, in the everyday needs of men and women is the determining factor in willingness to continue exercising fishing and shell fishing on Guaraíra Lagoon, space representing relations social, practices and customs transmitted in the course of local history through social memory of the oldest to the youngest.

Aplicação do exame da proporcionalidade diante da implantação de empreendimentos eólicos em áreas de preservação permanente

The setting up of wind power enterprises at Permanent Preservation Areas reflects the obvious conflict and necessary convergence between free market and energy security on the one hand, and the promotion of environmental quality on the other. From the perspective of energy sustainability, and in order to achieve development (in its complex meaning, which converges economic, social, environmental and cultural aspects), the harmonization between free market and an ecologically sustainable environment is required. This work aims to identify the link between the protection system of the Permanent Preservation Areas and the current constitutional order, by analyzing the implementation of wind power enterprises in these protected zones focusing on the proportionality aspects. A legal and purposeful research was developed, from a theoretical method, followed by collecting and analyzing both primary and secondary data. From these data, the law, the legal literature and judicial decisions were cross-examined, under the light of the Constitution and guided by the theory of proportionality and related development imperatives. In this context, the present study identified the link between the principles of the economic order, environment and energy law, finding their basis under the Federal Constitution and development. By reproducing this interrelationship and by means of post-crisis institutional reforms, the guiding objectives of the Brazilian electric sector began to corroborate the precepts of development, although issues regarding its sustainability still persist. The appraisal of proportionality indicates that the Permanent Preservation Areas protection system is insufficient to materialize the right to a healthy quality of life upon the implementation of wind projects at Permanent Preservation Areas, albeit seeking the harmonization between free market and environmental protection.

“Escritores da liberdade”: histórias reais de jovens que cumpriram medidas socioeducativas em meio aberto no município do Natal/RN

Such work aims to analyze aspects of the lives of adolescents, authors of Infraction, after completion of the Socio-Educational Measures in Half Open (Probation - LA and Services to the Community - PSC) in the city of Natal / RN in 2010. Thus, it become necessary to point out and consider the socio-historical determinations that permeate the lives of these young men, estimating the economic, social, political and historical aspects. We understand that these individuals experience numerous expressions of Social Issues, such as lack of opportunities, violence, unemployment, among others. In the reduction context of the State actions for the social, and investments negligible in public policies. Thus, the research aimed to identify such determinations in the lives of adolescents, young people today, and aimed to know these adolescents and analyze the family situation, socio-economic and political these, after completion of educational measures; and to evaluate the inclusion in school life and in the labor market. Therefore, we used as a methodological way the qualiquantitative research, using the procedure of 4 (four) semi-structured interviews, 9 (nine) analysis processes by configuring so documentary research, through the analysis of reports, processes and monitoring documents. The universe of analysis went adolescents who fulfilled socio-educational measures in liberty in the city of Natal / RN. The sample consisted of nine (9) young, that we follow during the mandatory curricular training, in the period of graduation in Social Work at the Federal University of Rio Grande do Norte, in 2010. The time frame of the research took place between 2010 - 2014. The results of this study indicate that the solution to problems of violence is not the reduction of criminal majority. It is necessary to take actions in ensuring rights and allow other living conditions to the children and adolescents, because, in fact, in the society there is a tendency to regression of rights. We learn that, despite all the difficulties, as: low education, access to the labor market, low income, among others, young people interviewed understand the Socio-Educational Measures such as a watershed in their lives, because, they do not practice more illicit acts, they seek a better life, they have dreams and plans for the future, and they continue writing their histories.

Vernaculares: a casa de fazenda seridoense do século XIX como exemplo de adaptação ao clima semiárido

The farm’s rural dwellings of creation from the Seridó Potiguar microregion, built in the nineteenth century, became a reference by its vernacular character, i.e. these buildings, besides having recognized relevance to the identity of the region, they are adapted to the conditions of the place in many aspects (economic, cultural, construction, physical, et.) and consist in protective spaces in relation to hostile characteristics of Seridó’s climate. Considering the above premise, the following question arises: What characteristics of the nineteenth century Seridó Potiguar’s cattle farms are crucial for them to be a protective space in relation to the semiarid climate? In order to answer the question, this research aim to identify which particularities of the Seridó’s farmhouses that contribute to adaptability in these buildings to semiarid climate, as protection environments; and contribute to the stock valuation of the architectural heritage concerned. Therefore, procedures were adopted divided into two stages. Were first identified the recurring characteristics in the studied buildings, through typological study performed from existing inventories (DINIZ, 2008; FEIJÓ, 2002; IPHAN, 2012). To define the type it worked up with the concept that merges Durand’s analytical typology that identifies the similarities and differences to classify buildings, having the character of historical survey and architectural documentation, with the definition proposed by Argan (1963) that the type is not defined a priory, but the deduction from a number of illustrative cases which have formal and functional similarity with each other. Then worked up in a sample of five different types with each other, defined by the possibility of access to the interior of the houses, proximity to other copies, good state of conservation and preservation. The contemplated farms were: Pitombeiras, Agenus e Garrotes in Acari’s town, and the municipality of Caicó, Palma and Penedo. The second stage consists of the architectural survey, photographic record, digital three-dimensional modeling (aiming to expand the existing documentation and registration) and thermal monitoring over approximately a representative day in five farmhouses, relating the thermal performance of the houses with their individual characteristics. The selected variables for analysis monitoring are based on the thermal comfort adaptive model (SPAGNOLO and DE DEAR, 2003 apud NEGREIROS, 2010). The characteristics of the houses were analyzed as meeting the passive thermal conditioning strategies recommended by NBR 15220 (ABNT, 2005), for the bioclimatic zone 7 where the municipalities of Caicó and Acari are located. The house’s analysis of the operating temperatures revealed that 90% of the times of day the environments are within the comfort range. The farmhouses, which had a higher degree of compliance with recommended bioclimatic strategies, had the best thermal performance. In environments (usually the kitchen and rooms with low ceiling heights, exposed to west radiation) which still had discomfort hours, the thermal comfort can be reached with air movement approximately 1,0 m/s.
