Thus, we analyzed a series of experiments performed between 1786 and 1804 elaborated by him to investigate about the modes of heat communication. A carefully examination of these experiments and arguments presented by Rumford shows us that the process of the elaboration of his hypothesis was gradual and that took into account not only experimental questions, but also theoretical ones. Through this analysis, we concluded that Rumford took almost twenty years to admit the existence of an ethereal fluid and to present the definite version of his hypothesis that the heat was propagated through undulations in ether / O objetivo desse trabalho é compreender em que momento e por quais razões o conde Rumford passou a admitir a existência de um fluido etéreo para sustentar sua hipótese sobre os meios de propagação do calor. Para tanto, analisamos uma série de experimentos realizados entre 1786 e 1804, que foram elaborados por ele para investigar sobre os modos de comunicação de calor. Um cuidadoso exame desses experimentos e dos argumentos apresentados por Rumford mostra-nos que o processo de elaboração de sua hipótese foi lenta e que levou em consideração não só questões de ordem experimental, mas também teórica. Por meio desta análise, concluímos que Rumford levou quase vinte anos para admitir a existência de um fluido etéreo e apresentar a versão definitiva de sua hipótese de que o calor se propagava por meio de ondulações no éter

In 1890, paper magnate Hugh Chisholm chartered the Portland & Rumford Falls Railway to provide service between Maine's largest city and the nascent industrial community of Rumford Falls. From 1890 to 1897, directors of that railroad embarked upon a cohesive building program to distinguish its stations from competitors and to attract traffic to Rumford Falls. This railroad's program represents a seminal moment in small town railroad station architecture because it was an early manifestation of a planned, replicated design. Civil engineer Frederic Danforth implemented the comprehensive landscape developed by architect Edwin Lewis. This pattern of architect-driven designs would be developed in the early twentieth century by railroad companies nationwide as they more aggressively created corporate branding, while also balancing community relations. In 1894, Chisholm and associates chartered a second rail line, the Rumford Falls & Rangeley Lakes Railroad, to service nearby timberlands and outdoor sporting locales. This line would further increase the prowess of Rumford Falls and the profitability of the Portland & Rumford Falls Railway. Lewis was not associated with this project, but its directors maintained a complementary architectural program almost indistinguishable from the earlier campaign. This thesis examines the initial development of the two rail lines based on photographs, architectural drawings, and documentary research. It explores how these building programs fit into the greater schema of corporate railroad architectural development. It elucidates the national trends toward an interconnected industrial landscape and early attempts at corporate branding through vernacular architecture.

Here we have analyzed the radiation of cold experiment performed by Rumford in 1802 and its theoretical implication concerning the heat. Regarding this we reviewed some Rumford s early studies which led us to a better understanding of his trajectory until he could perform his experiment. We can say that the hypothesis adopted by Rumford related to the nature of heat determined decisively the interpretation given by him to the experiment results. We consider here original texts published by Rumford, specially An Experimental Inquiry Concerning the Source of Heat Which is Excited by Friction in which he described his radiation of cold experiment. Through this study we concluded that although experiments results are very important for the construction of knowledge, they are not sufficient to validate or refute a hypothesis definitely / O objetivo desse trabalho é compreender o papel do experimento na construção do conhecimento. Analisamos o experimento da radiação do frio realizado pelo Conde Rumford em 1802, e suas implicações de natureza teórica em relação à concepção de calor. Para tanto, revisamos alguns estudos anteriores realizados por Rumford que propiciaram uma melhor compreensão de sua trajetória até ele realizar o experimento. Podemos dizer que a hipótese adotada por Rumford sobre a natureza do calor, determinou de forma decisiva a interpretação dada aos resultados experimentais. Para a realização dessa pesquisa recorremos a textos originais publicados pelo Conde Rumford, principalmente aquele em que ele descreve o experimento da radiação do frio. Por meio desta análise, concluímos que, apesar de muito importante para a construção do conhecimento, o resultado experimental não é suficiente para validar ou refutar uma hipótese definitivamente

No. of bitstreams: 1 Edaival Mulatti.pdf: 1316493 bytes, checksum: 2ddebbfbb24364b182ea454f86c50397 (MD5) Previous issue date: 2008-10-23 / The Royal Institution, English organization founded at the end of the eighteenth century in London and existing in this day and age as an institution dedicated to research in the theory and dissemination of science, was born with the purposes of an institution of public character, depending on financial contributions. Within a conception of science, categorized by its founders as "useful science," the Royal Institution had as main goals, the diffusion of knowledge and application of science in the life of the population. For the present work, we studied up some of the social and political circumstances present in England at the end of the eighteenth century, and provided evidence to the understanding of the reasons that enabled the creation of that institution. Also, we tried to identify in the creation and consolidation of that institution, the role played by personalities of the time, as Joseph Banks, Benjamin Thompson, Thomas Young, Thomas Garnett and Humphry Davy. This work was based on the study of the following documents: "Proposals for forming by subscription, in the Metropolis of the British Empire, the Public Institution for diffusing the knowledge and facilitating the general introduction of useful mechanical inventions and improvements, and for teaching, by Philosophical Lectures and courses of Experiments, the application of science to the common purposes of life.", document-creation of the Royal Institution, authored by Benjamin Thompson and dated March 1799,"The discourse introductory to the Course of Lectures on Chemistry , Delivered in the Theatre of the Royal Institution, on the 21st of January, 1802," inaugural lecture of the Royal Institution Humphry Davy, and "The Bakerian Lecture, on some chemical Agencies of Electricity," lecture in which Davy presented the results of their research on electrolysis, made the Royal Institution and presented at the Royal Society on November 20 de1806. The focus of this work was in the study of the model for dissemination of knowledge established on the origins of the Royal Institution, as well as some of the changes that have made this model a strong point of support for the Royal Institution to be seen, at the beginning of the nineteenth century, as a major scientific institutions of England / The Royal Institution, organização inglesa fundada no final do século XVIII em Londres e existente nos dias de hoje como uma instituição voltada a pesquisas no campo teórico e divulgação da ciência, nasceu com os propósitos de uma instituição de caráter público, dependendo financeiramente de contribuições. Dentro de uma concepção de ciência, categorizada por seus fundadores como ciência útil , a Royal Institution tinha como principais objetivos, a difusão do conhecimento e aplicação da ciência na vida da população. Para o presente trabalho, estudou-se algumas das circunstâncias sociais e políticas presentes na Inglaterra no final do século dezoito, e que forneceram elementos para o entendimento dos motivos que propiciaram a criação de tal instituição. Procurou-se também identificar, na criação e consolidação dessa Instituição, o papel desempenhado por personalidades da época, como Joseph Banks, Benjamin Thompson, Thomas Young, Thomas Garnett e Humphry Davy. Esta dissertação baseou-se no estudo dos seguintes originais: Proposals for forming by subscription, in the Metropolis of the British Empire, a Public Institution for diffusing the knowledge and facilitating the general introduction of useful mechanical inventions and improvements, and for teaching, by courses of Philosophical Lectures and Experiments, the application of science to the common purposes of life , documento de criação da Royal Institution, de autoria de Benjamin Thompson e datado de março de 1799, A discourse introductory to a Course of Lectures on Chemistry, Delivered in the Theatre of the Royal Institution, on the 21st of January, 1802 , palestra inaugural de Humphry Davy na Royal Institution, e The Bakerian Lecture, on some chemical Agencies of Electricity , palestra na qual Davy apresentou os resultados de suas pesquisas sobre eletrólise, efetuadas na Royal Institution e apresentadas perante a Royal Society em 20 de novembro de1806. O ponto central desse trabalho situou-se no estudo do modelo de difusão do conhecimento formulado nas origens da Royal Institution, bem como em algumas de suas modificações que fizeram desse modelo um forte ponto de apoio para que a Royal Institution se projetasse, no início do século dezenove, como uma das principais instituições científicas da Inglaterra
