Nos países em desenvolvimento, como o Brasil, a secagem de produtos agrícolas com uso de secador solar representa uma alternativa promissora de baixo custo, reduzindo perdas e agregando valor aos produtos. Porém, devido à natureza periódica da radiação solar e das condições do tempo, nem sempre é viável sua utilização. Dessa forma, o objetivo do trabalho foi a modelagem de um sistema auxiliar de armazenagem de energia térmica (SAET) em um secador solar, cuja finalidade é armazenar energia durante o dia para ser utilizada conforme necessário. Com base em registros de temperatura e umidade relativa, ambas do ar, de um secador solar, foi feito um estudo da termodinâmica dos processos envolvidos, a fim de propor meios para o dimensionamento do SAET. Foram explorados a estimativa do fluxo de massa de ar no secador, a modelagem da temperatura em função da radiação, e o dimensionamento para diferentes modos de operação do SAET, considerando o sistema ideal. Este dimensionamento tratou tanto do caso de fornecimento contínuo de fluxo de água preaquecida, como de uso de automação para controlar o fluxo. A estimativa de fluxo de ar no secador se aproximou de valores típicos encontrados na literatura. O dimensionamento do sistema, embora considerado ideal, mostra que a utilização do SAET melhora o desempenho do secador, servindo como parâmetro para melhor compreender o comportamento das variáveis durante seu funcionamento. / In developing countries such as Brazil, drying of agricultural products by using solar dryer is a promising low cost alternative to reduce losses and add value to products. However, due to periodic behavior of solar radiation and weather conditions, the use of solar drier is not always feasible. The objective of this study is to model an auxiliary thermal energy storage (ATES) in a solar drier, aiming to store energy during the day to be used as needed. Based on both air temperature and relative humidity records of a solar dryer, the thermodynamics of the underlying processes was studied in order to propose means for designing the ATES. It was addressed the estimative of the air mass flow in the dryer, the modeling of the temperature as a function of the radiation, and the designing of the ATES for different modes of operation, considering the optimal system. The designing dealt with both the continuous supply of preheated water flow and the use of automation for controlling the flow. The estimated air flow in the dryer approached typical values found in the literature. The designing of the system, although considered ideal, shows that the use of ATES improves the drying performance, serving as a parameter to better understand the behavior of variables during operation.

Tal estudo foi feito com base na obra de Michel Foucault. A hipótese motivadora foi possuir o Direito um caráter essencialmente excludente em sua gênese. Para construir a discussão teórica foi utilizado como grupo representativo os catadores de material reciclável, por reunirem características que os tornam representantes da parcela sócio, econômica e politicamente mais excluída no Brasil. / The present dissertation sought to investigate the possibility of the Democratic State of Law in fact extending its protective sphere in an equitable way to all individuals and groups of a society, starting with French post-structuralism and its criticism of this same Democratic State of Law as a civilizing milestone. This study was based on the work of Michel Foucault. The motivating hypothesis was to have the Law an essentially exclusionary character in its genesis. In order to construct the theoretical discussion, recyclable material collectors were used as a representative group because they have characteristics that make them representatives of the socioeconomic and politically excluded part of Brazil.

Que ce soit au niveau des musées, du marché de l’art et des collections privées, Paris se défini aujourd’hui comme une place centrale de l’activité du monde des arts d’Afrique Noire. Outre l’actualité muséographique des arts d’Afrique Noire, avec l’inauguration en avril 2000 de la salle du pavillon des Sessions au musée du Louvre, puis l’ouverture du musée du quai Branly en juin 2006 ; Paris doit aussi sa place de capitale du monde des arts d’Afrique Noire par la centralisation des activités du marché de l’art de cette spécialité en son sein.D’ailleurs, nos travaux montrent que le rôle joué par la sphère privée des marchands et des collectionneurs est primordial dans l’homologation esthétique et la définition de la hiérarchie des valeurs esthétiques aujourd’hui admises dans la spécialité des arts d’Afrique Noire.Cette thèse de doctorat est aussi l’occasion de rappeler pourquoi le monde des arts d’Afrique Noire est une invention des pays de culture occidentale et permet d’appréhender avec plus d’objectivité l’appropriation occidentale du patrimoine artistique ancien et traditionnel issu de l’Afrique Subsaharienne / Whether it’s at the level of museums, the art market, or private collections, Paris is defined today as a central place of world activity, for ‘Black African’ arts. Beyond the reality, museographically speaking of Black African arts, with the inauguration of the Pavillion Hall of Sessions at the Louvre Museum in April 2000, and then the opening of the Quai Branly Museum in June 2006 ; Paris also credits it’s positions as the world’s capital of Black African arts by the centralisation of the art market’s activities of this speciality in it’s heart.Elsewhere, our works show that the role played by the private sphere of traders and of collectors is primordial in the aesthetic homologation and the definition of the hierarchy of aesthetic values today admitted in the speciality of ‘Black African’ arts.This doctorate thesis is also the occasion to recall why the world of ‘Black African’ arts is an invention of countries of western character, and allows to apprehend with more objectivity to western adapatation of ancient artistic heritage and traditional descent from the Sub-Saharan Africa.

Cette étude, dans sa description du contexte historique et culturel de Naples autour des années 30 du XIX siècle, s’est orientée, en premier lieu, vers la recherche de la bibliographie plus ancienne (P. Colletta etc) ainsi que sur le dépouillement systématique des vingts volumes du journal “Monitore Napoletano”. Parallèlement elle commence l’étude des anciens guides de la ville, auprès de la Bibllioteca Nazionale de Naples, afin de retrouver les descriptions des collections privées napolitaines, des collectionneurs et du gout artistique de l’époque, la circulation des tableaux parmi les plus prestigieuses collections du royaume, ainsi que les premières descriptions des appartements du prince Leopoldo au Palais Royal de Naples. / The present study in describing the historical and cultural context around Naples the 30 years of the nineteenth century, it is oriented in the first instance, to seek oldest bibliography (P. Colletta, B. Croce, A. Acton, etc.) and to carry out the systematic examination of the twenty volumes of the newspaper "Neapolitan Monitor". In parallel, it was started the study of the ancient city guides, at the National Library of Naples in order to trace the descriptions of the collections Private Neapolitan, collectors and the artistic taste of the time, circulation the paintings in the most prestigious collections of the kingdom, and the first descriptions Prince Leopold of the apartments at the Royal Palace of Naples. / Il presente studio nel descrivere il contesto storico e culturale di Napoli attorno agli anni 30 del XIX secolo, si è orientato, in prima istanza, nel ricercare la bibliografia più antica (P. Colletta, B. Croce, A. Acton, etc.) e ad effettuare lo spoglio sistematico dei venti volumi del giornale «Monitore Napoletano». Parallelamente, ha preso l’avvio lo studio delle guide antiche della città, presso la Biblioteca Nazionale di Napoli al fine di rintracciare le descrizioni delle collezioni private napoletane, dei collezionisti e il gusto artistico del tempo, la circolazione dei dipinti nelle più prestigiose collezioni del regno, nonché le prime descrizioni degli appartamenti del principe Leopoldo a Palazzo Reale di Napoli.

Circonscription fiscale se superposant presque exactement, en pays de taille personnelle, à la paroisse, la communauté d’habitants forme, avec la seigneurie, le pole principal d’encadrement de la vie rurale. Bénéficiant d’une grande indépendance aux premiers temps du XVIe siècle, les villages de Forez sont très faiblement institutionnalisés et la vie institutionnelle repose sur une confusion de toutes les obligations communes en un seul lieu de délibération : l’assemblée. Ils vont cependant être confrontés à l’effort de centralisation entrepris par la monarchie. Leur fonctionnement institutionnel, rudimentaire, reposant sur une assemblée générale unique, et sur des consuls élus pour remplir les obligations collectives du village, ne va pas résister aux contraintes que leur imposent l’Etat moderne et le poids toujours croissant de sa fiscalité. L’autonomie des villages de Forez va donc décliner à mesure que s’affermit la monarchie absolue. Ainsi, jusqu’aux années 1670, la vie institutionnelle des villages de Forez est essentiellement interne au village. L’empiètement croissant des autorités extérieures amène cependant à un meilleur contrôle sur l’effectivité des obligations qui pèsent sur le village. De cette double contrainte d’obligations plus lourdes et d’un contrôle accru, résulte une transformation des institutions villageoises qui vont renforcer leur structure mais perdre la spontanéité qui présidait à leur fonctionnement aux premiers temps de l’Ancien Régime. Leur organisation sera alors plus identifiable, mais le fonctionnement radicalement différent : la compacité qui caractérisait le village s’est perdue dans une participation institutionnelle. / Tax district almost overlapping the parish in a land of personal taxes, the rural community is, with the lordship, the main pole framing the rural life.Enjoying considerable independence in the early days of the sixteenth century, the villages of Forez are very weakly institutionalized and the life of their institutions is based on a confusion of all bonds in one common place of deliberation. However they will be faced with the centralization effort undertaken by the monarchy. Their institutional functioning, rudimentary, based on a single meeting, and consuls elected to fulfill the collective obligations of the village, will yield to the constraints imposed on them by the modern state and its ever-increasing weight of taxation. The autonomy of villages will therefore decline as an absolute monarchy was strengthened.Thus, until the 1670s, the institutional life of the villages of Forez is essentially internal. The increasing encroachment of outside authorities, however, leads to greater control over the effectiveness of the obligations imposed on the village. This double bind, more onerous obligations and increased control, brings transformation of village institutions. Their organization will be more identifiable but operating in a radically different way : compactness that characterized the village was then lost in an institutionalized participation.
