Deviations of cup anemometer rotational speed measurements due to steady state harmonic accelerations of the rotor

The measurement deviations of cup anemometers are studied by analyzing the rotational speed of the rotor at steady state (constant wind speed). The differences of the measured rotational speed with respect to the averaged one based on complete turns of the rotor are produced by the harmonic terms of the rotational speed. Cup anemometer sampling periods include a certain number of complete turns of the rotor, plus one incomplete turn, the residuals from the harmonic terms integration within that incomplete turn (as part of the averaging process) being responsible for the mentioned deviations. The errors on the rotational speed due to the harmonic terms are studied analytically and then experimentally, with data from more than 500 calibrations performed on commercial anemometers.

Use of infrared thermography as a tool to monitor skin temperature along the recovery process of an anterior cruciate ligament surgery

Infrared thermography (IRT) is a safe and non-invasive tool used for examining physiological functions based on skin temperature (Tsk) control. Thermograms from 25 anterior cruciate ligament (ACL) surgically operated patients (2 female, 23 male) were taken with a FLIR infrared camera according to the protocol established by the International Academy of Clinical Thermology (IACT). This work consists of 4 studies. Studies 1 and 3 were related to establish the probable thermal difference among different moments of an ACL rupture after surgery: before starting the rehabilitation (P0), at the end of rehabilitation (P1) and 18 months from the end of rehabilitation (P2). For this purpose, on the other hand, studies 2 and 4 were related to establish the skin thermal difference (Tsk) between the injured and the non-injured leg in P0, P1 and P2. Results of the first study showed significant temperature increases in the posterior thigh area between P0 and P1 probably due to a compensatory mechanism. According to this, we can conclude that temperature of the posterior area of the injured and noninjured leg has increased from the first to the last day of the rehabilitation process. In the second study we found significant temperature differences between the injured and non-injured leg in both stages of rehabilitation (p<.01). On the one hand, the temperature of the injured leg is higher in the anterior view and the temperature of the non-injured leg is higher in the posterior view. By the time the patients had recovered from the reconstruction, thermal imbalances should have not been shown between symmetrical parts, but differences seemed to be still latent.. Study 3 shows that temperatures seem to be higher after a year and a half (P2) than in P1. Study 4 shows how thermal values 18 months later seemed to be normalized between both legs. No significant differences were found between the injured leg and the noninjured leg after one year and a half of the rehabilitation process. Considering results from Study 3 and 4 we can conclude that patients seemed to have recovered from a thermal point of view. The temperature in P2 was higher but symmetrical. RESUMEN La termografía infrarroja (IRT) es una herramienta segura y no invasiva utilizada para examinar funciones fisiológicas que se basan en el control de temperatura de la piel (Tsk). Termogramas de 25 pacientes intervenidos quirúrgicamente del ligamento cruzado anterior (LCA) (2 mujeres, 23 hombres) fueron tomadas con una cámara de infrarrojos FLIR de acuerdo con el protocolo establecido por la Academia Internacional de Termología Clínica (IACT). Este trabajo consiste en 4 estudios. Los estudios 1 y 3 describen la diferencia térmica entre los diferentes momentos tras la operación del ligamento cruzado anterior: antes de comenzar la rehabilitación (P0), al final de la rehabilitación (P1) y 18 meses tras finalizar la rehabilitación (P2). Por otra parte, los estudios 2 y 4 describen la diferencia de temperatura de la piel (Tsk) entre la pierna lesionada y la pierna no lesionada en P0, P1 y P2. Los resultados del primer estudio mostraron aumentos significativos de temperatura en la zona posterior de los muslos entre P0 y P1, probablemente debido a un mecanismo de compensación. De acuerdo con esto, se puede concluir que la temperatura de la zona posterior de la pierna lesionada y no lesionada se ha incrementado desde el primero hasta el último día del proceso de rehabilitación. En el segundo estudio se encontraron diferencias significativas de temperatura entre la pierna lesionada y no lesionada en ambas etapas de la rehabilitación (p<.01). Por un lado, la temperatura de la pierna lesionada es mayor en la vista anterior. Por otro lado, la temperatura de la pierna no lesionada es mayor en la vista posterior. Una vez que los pacientes se han recuperado de todo el proceso, no deberían existir desequilibrios térmicos entre partes simétricas del cuerpo, pero las diferencias todavía estaban latentes. El tercer estudio muestra que la temperatura es más alta en P2 que en P1. El cuarto estudio muestra cómo los valores térmicos entre ambas piernas en P2 se han normalizado entre ambas piernas. No se encontraron diferencias significativas entre la pierna lesionada y la pierna no lesionada después de 18 meses tras el proceso de rehabilitación. Considerando los resultados del studio 3 y 4, podemos concluir que se ha llegado a la recuperación total desde un punto de vista térmico. La temperatura es más elevada en P2 pero simétrica.

O PSC E A NOÇÃO DE “FAMÍLIA TRADICIONAL” COMO IDENTIDADE PARTIDÁRIA E RELIGIOSA: ANÁLISE DO PROCESSO ELEITORAL DE 2014

A presente dissertação analisa como o Partido Social Cristão (PSC), ao longo do tempo, se apropriou da identidade religiosa de seus atores políticos que na sua maioria são membros da Frente Parlamentar Evangélica, os quais defendem no espaço público a “família tradicional”, em detrimento da pluralidade de arranjos familiares na contemporaneidade. Para explicitar o objeto - “família tradicional” e PSC -, foi necessário retroceder no tempo e investigar na historiografia os primórdios da inserção dos evangélicos na política brasileira. Em vista disso, analisamos a participação dos evangélicos nos respectivos períodos do Brasil: Colônia, Império e República. A dificuldade da entrada de evangélicos na política partidária, dentre outros fatores, se deve àinfluência do catolicismo no Estado. Assim sendo, averiguamos em todas as Constituições (1824, 1891, 1934, 1937, 1946, 1967, 1969 e 1988) o que a mesma diz no que tange a proibição e a liberdade religiosa no país. Logo, verificamos entre as Eras Vargas e República Populista, que ocorreu com intensidade a transição do apoliticismo para o politicismo entre os evangélicos brasileiros, porém, eles não recebiam o apoio formal de suas igrejas. Em seguida, a participação dos evangélicos na arena política durante a ditadura militar foi investigada com destaque para o posicionamento de vanguarda da IECLB, através do Manifesto de Curitiba e, também com a presença de parlamentares evangélicos no Congresso Nacional. A politização pentecostal é ressaltada em nosso trabalho, através do pioneirismo de Manoel de Mello e, depois na Redemocratização quando as instituições evangélicas se organizaram para eleger seus candidatos à Assembleia Nacional Constituinte. E, com o fim do regime militar, o PSC surge como partido “nanico”, contudo, deixa o anonimato e ganha visibilidade midiática quando o pastor e deputado, Marco Feliciano, assume a presidência da Comissão de Direitos Humanos e Minorias, em 2013. Esse é o pano de fundo histórico que projetou o PSC e seus atores no pleito de 2014 com o mote “família tradicional”.

Gerenciamento integrado de resíduos sólidos: estudo de caso no Instituto Butantan

A relevância do gerenciamento de resíduos sólidos justifica-se pelos impactos à saúde e ao meio ambiente. Resíduos gerados em serviços de saúde podem apresentar periculosidade por suas características físico-químicas e biológicas. No Brasil, todo grande gerador é obrigado a elaborar o Plano de Gerenciamento de Resíduos Sólidos, e todo estabelecimento de saúde deve criar o Plano de Gerenciamento de Resíduos de Serviços de Saúde. Objetivo: Desenvolver modelo de gestão de resíduos sólidos para apoiar a elaboração e implantação desses planos em instituições públicas de pesquisa, desenvolvimento e fabricação de produtos de saúde. Métodos: Estudo de caso conduzido no Instituto Butantan, localizado no município de São Paulo/SP. Foi realizado considerando as seguintes etapas: diagnóstico do gerenciamento dos resíduos e elaboração, implantação e avaliação de Plano Integrado de Gerenciamento de Resíduos Sólidos. Todo o processo teve como abordagem a gestão participativa, compartilhada e integrada, envolvendo todos os atores da instituição. Na avaliação foram considerados o atendimento legal quanto à gestão e gerenciamento, às práticas e procedimentos implantados e à atuação dos envolvidos. Resultados: Destacam-se a caracterização e quantificação para cada fluxo de resíduos, a elaboração do Guia Prático de Descarte de Resíduos, o Modelo de Gestão para instituições de pesquisa, desenvolvimento e fabricação de produtos de uso em saúde humana baseado nas premissas do ciclo PDCA e o sistema informatizado de gerenciamento para estruturação e controle da gestão dos resíduos. Conclusões: Verifica-se que o processo desenvolvido ao longo do estudo propiciou mudança de cultura, envolvimento dos funcionários por meio da capacitação contínua para atuação e segurança do trabalhador e melhoria no gerenciamento dos resíduos, promovendo a redução de custos de destinação e a valorização dos resíduos.

O papel do terceiro facilitador na conciliação de conflitos previdenciários

A conciliação judicial de conflitos previdenciários envolve, em geral, uma proposta de acordo baseada na renúncia pelo indivíduo de parte dos valores do benefício em atraso em um processo no qual a decisão contrária ao entendimento do Instituto Nacional do Segurado Social (INSS) é muito provável. Como regra, há um notório desequilíbrio de poder envolvendo, de um lado, um litigante ocasional (indivíduo) e, de outro, um litigante habitual (INSS). O presente trabalho pretende discutir qual o papel do terceiro facilitador nesse contexto, de modo a legitimar a prática existente e avançar para uma mudança de paradigma. Para tanto, parte-se da tese de que a conciliação deve ser adequada ao conflito que se pretende tratar, cabendo ao terceiro facilitador atuar de acordo com as peculiaridades desse conflito. Desse modo, propõe-se que, para o tratamento do conflito previdenciário, o conceito de conciliador deve ser entendido em termos amplos, abrangendo não apenas o conciliador leigo, mas também o juiz conciliador e o Judiciário como conciliador interinstitucional. Embora cada uma dessas atuações possua características próprias, sustenta-se que o ponto em comum é o respeito a um devido processo legal mínimo que possibilite a existência de uma base adequada de poder e que permita, assim, a tomada de uma decisão informada pelas partes. Dessa forma, a flexibilidade instrumental própria da conciliação não impediria o estabelecimento de parâmetros mínimos da atuação do conciliador. Por isso, tendo como limite a tomada de uma decisão informada, o conciliador atuaria por meio de estratégias variadas, aproximando-se e distanciando-se das partes, com maior ou menor interferência, de acordo com as características do caso apresentado. Conclui-se que, com a atuação conjunta e coordenada das diversas espécies de conciliador é possível aprimorar qualitativamente a conciliação de conflitos previdenciários.

Reciclagem de resíduos eletroeletrônicos: um estudo cinético da lixiviação ácida de ferro de placas de circuito impresso de microcomputadores.

O aumento no consumo mundial de novos aparelhos eletroeletrônicos aliado à redução no tempo de vida útil destes equipamentos tem como principal consequência ao meio ambiente a geração de resíduos. No Brasil, com a instituição da Política Nacional de Resíduos Sólidos, criou-se a obrigatoriedade legal da responsabilidade dos fabricantes pela logística reversa dos equipamentos eletroeletrônicos, incentivando pesquisas para o desenvolvimento dos métodos de reciclagem e tratamento dos materiais descartados. O processo de lixiviação foi avaliado como alternativa à etapa de separação magnética presente nas atuais rotas hidrometalúrgicas para recuperação de metais valiosos de placas de circuito impresso. Para avaliar a composição das placas, foi realizado ensaio de dissolução em água régia. As amostras foram moídas e submetidas a ensaios de lixiviação com ácido sulfúrico nas concentrações de 1 e 2mol/L, às temperaturas de 75ºC, 85ºC e 95ºC, durante 24 horas. Com ácido sulfúrico 2mol/L a 95ºC, o tempo necessário para se obter 100% de extração do ferro foi de 2 horas. Nestas condições, não foi detectada a presença de cobre dissolvido. A cinética da reação é controlada por reação química e obedece a equação .=1(1)3. A energia de ativação aparente do processo equivale a 90kJ/mol.

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.

Fracking/Takings

As the use of fracking has spread during the recent oil and gas boom, inevitable conflicts have arisen between industry and its neighbors, particularly as fracking has moved into densely populated urban and suburban areas. Concerned over the impacts of fracking – such as risks to health and safely, diminished property values, air and water pollution, as well as noise, traffic, and other annoyances – many people have demanded a government response. Government regulation of fracking has struggled to catch up, although in recent years many state and local governments have taken steps to reduce the impacts of fracking in their communities. This article focuses on government restrictions in New York and Colorado, two of the key battlegrounds in the fight over fracking. New York recently prohibited fracking across the entire state, after several towns had enacted their own bans. In Colorado, the people have used the ballot initiative process to enact restrictions on fracking directly. The industry has responded not only with public relations spending to improve the fracking’s damaged reputation, but also legal challenges to these efforts to rein in oil and gas development. In addition to suing local governments, often arguing they do not have authority to regulate fracking, industry threatens to bring costly takings claims for compensation due to alleged economic harms. This Article examines the numerous legal and factual issues that should make it difficult for industry to succeed on fracking/takings claims. First, regulation of fracking, even including outright bans, can almost always be defended as necessary to prevent a nuisance or other background principle of law that justifies government regulation. Even if a nuisance defense could be overcome, industry would have difficulty proving that regulation has destroyed all economic value in their property, unless courts take a narrow view of property that would highlight the arbitrary nature of the “denominator problem.” When fracking/takings claims are considered under the default balancing of the Penn Central case, takings are unlikely to be found except in rare outlier cases. Finally, because requiring governments to pay compensation in fracking/takings cases would likely create a windfall for industry, particularly if the oil and gas eventually is extracted in the future, courts should resist the temptation to rule against government restrictions to protect public health, safety, and the environment.

Legal, Ethical and Cultural Issues U.S. companies face when moving operations to China.

Beyond free trade agreements governing cross-border commerce, the source of most global economic growth is attributed to business across interconnecting markets. Among the most attractive and complex markets, China stands out. Despite its appeal, American businesses are more likely to fail in China due to an overwhelming desire for an immediate return on investment while neglecting to consider or completely disregarding China's unique legal, ethical and cultural environment. This capstone project will give recommendations to help businesses succeed when entering China and avoid legal, ethical and cultural issues such as the ones that Google, Apple, and Yahoo experienced.

Thermal decomposition of the different particles size fractions of almond shells and olive stones. Thermal behaviour changes due to the milling processes

The aim of this study is to investigate the effect of particle size on the non-isothermal pyrolysis of almond shells (AS) and olive stones (OS) and to show possible differences in the composition of the different fractions obtained after milling and sieving. The results obtained from the study of different particle size of AS and OS samples show significant differences in the solid residue obtained and in the shape and overlapping degree of the peaks, especially with the smaller particle size. These differences can be due to different factors: (a) the amount of inorganic matter, which increases as particle size decreases, (b) heat and mass transfer processes, (c) different sample composition as a consequence of the milling process which may provoke changes in the structure and the segregation of the components (in addition to the ashes) increasingly changes the composition of the sample as the particle size decreases.

MINLP Model for the Synthesis of Heat Exchanger Networks with Handling Pressure of Process Streams

This paper introduces a new mathematical model for the simultaneous synthesis of heat exchanger networks (HENs), wherein the handling pressure of process streams is used to enhance the heat integration. The proposed approach combines generalized disjunctive programming (GDP) and mixed-integer nonlinear programming (MINLP) formulation, in order to minimize the total annualized cost composed by operational and capital expenses. A multi-stage superstructure is developed for the HEN synthesis, assuming constant heat capacity flow rates and isothermal mixing, and allowing for streams splits. In this model, the pressure and temperature of streams must be treated as optimization variables, increasing further the complexity and difficulty to solve the problem. In addition, the model allows for coupling of compressors and turbines to save energy. A case study is performed to verify the accuracy of the proposed model. In this example, the optimal integration between the heat and work decreases the need for thermal utilities in the HEN design. As a result, the total annualized cost is also reduced due to the decrease in the operational expenses related to the heating and cooling of the streams.

Semantic change and intersubjectification: The origin of reprise evidential conditional in Old Catalan

The reprise evidential conditional (REC) is nowadays not very usual in Catalan: it is restricted to journalistic language and to some very formal genres (such as academic or legal language), it is not present in spontaneous discourse. On the one hand, it has been described among the rather new modality values of the conditional. On the other, the normative tradition tended to reject it for being a gallicism, or to describe it as an unsuitable neologism. Thanks to the extraction from text corpora, we surprisingly find this REC in Catalan from the beginning of the fourteenth century to the contemporary age, with semantic and pragmatic nuances and different evidence of grammaticalization. Due to the current interest in evidentiality, the REC has been widely studied in French, Italian and Portuguese, focusing mainly on its contemporary uses and not so intensively on the diachronic process that could explain the origin of this value. In line with this research, that we initiated studying the epistemic and evidential future in Catalan, our aim is to describe: a) the pragmatic context that could have been the initial point of the REC in the thirteenth century, before we find indisputable attestations of this use; b) the path of semantic change followed by the conditional from a ‘future in the past’ tense to the acquisition of epistemic and evidential values; and c) the role played by invited inferences, subjectification and intersubjectification in this change.

The European Court of Justice and process-oriented review. Research Paper in Law, 01/2012

Structuralism is a theory of U.S. constitutional adjudication according to which courts should seek to improve the decision-making process of the political branches of government so as to render it more democratic.1 In words of John Hart Ely, courts should exercise their judicial-review powers as a ‘representation-reinforcing’ mechanism.2 Structuralism advocates that courts must eliminate the elements of the political decision-making process that are at odds with the structure set out by the authors of the U.S. Constitution. The advantage of this approach, U.S. scholars posit, lies in the fact that it does not require courts to second-guess the policy decisions adopted by the political branches of government. Instead, they limit themselves to enforcing the constitutional structure within which those decisions must be adopted. Of course, this theory of constitutional adjudication, like all theories, has its shortcomings. For example, detractors of structuralism argue that it is difficult, if not impossible, to draw the dividing line between ‘substantive’ and ‘structural’ matters.3 In particular, they claim that, when identifying the ‘structure’ set out by the authors of the U.S. Constitution, courts necessarily base their determinations not on purely structural principles, but on a set of substantive values, evaluating concepts such as democracy, liberty and equality. 4 Without claiming that structuralism should be embraced by the ECJ as the leading theory of judicial review, the purpose of my contribution is to explore how recent case-law reveals that the ECJ has also striven to develop guiding principles which aim to improve the way in which the political institutions of the EU adopt their decisions. In those cases, the ECJ decided not to second-guess the appropriateness of the policy choices made by the EU legislator. Instead, it preferred to examine whether, in reaching an outcome, the EU political institutions had followed the procedural steps mandated by the authors of the Treaties. Stated simply, I argue that judicial deference in relation to ‘substantive outcomes’ has been counterbalanced by a strict ‘process review’. To that effect, I would like to discuss three recent rulings of the ECJ, delivered after the entry into force of the Treaty of Lisbon, where an EU policy measure was challenged indirectly, i.e. via the preliminary reference procedure, namely Vodafone, Volker und Markus Schecke and Test-Achats.5 Whilst in the former case the ECJ ruled that the questions raised by the referring court disclosed no factor of such a kind as to affect the validity of the challenged act, in the latter cases the challenged provisions of an EU act were declared invalid.
