Travel literature and the development of the novel in eighteenth-century France
No full text"Travel Literature and the Development of the Novel in Eighteenth-Century France" follows the evolution of the French novel throughout the eighteenth century by examining the epistemological, aesthetic, and literary exchanges between historiography, travel literature, and the novel, three separate yet intertwined modes of representation that were in the process of creating or recreating their modern identities through a systematization of coherent literary rules. I argue that essential changes in the conceptualization and writing of history led to similar developments in the way travel accounts were written, organized, and consumed. As travel literature strengthened its own generic distinctiveness, novelists depicting foreign characters and/or landscapes selectively appropriated the legitimating discourse of travel literature to create an autonomous literary space for the novel. As these novels emulate travel literature, they critically incorporate the problematic questions of legitimacy of travel accounts, and force the novel's claims of truth to take place within a historical methodology discourse which in turn legitimizes it, delineating distinct profiles for history and fiction alike.Ph.D.Includes bibliographical references (p. 227-251)by Aya Tanak
Analysis of the September ε-Perseid outburst in 2013
No full text© 2018 The Author(s). Artículo firmado por 14 autores. We acknowledge support from the Spanish Ministry of Science and Innovation (projects AYA2015-68646-P and AYA 2015-67175-P).We analyze the outburst experienced by the September ε-Perseid meteor shower on 9 September 2013. As a result of our monitoring the atmospheric trajectory of 60 multistation events observed over Spain was obtained and accurate orbital data were derived from them. On the basis of these orbits, we have tried to determine the likely parent body of this meteoroid stream by employing orbital dissimilarity criteria. In addition, the emission spectra produced by two events belonging to this meteor shower were also recorded. The analysis of these spectra has provided information about the chemical nature of their progenitor meteoroids. We also present an estimation of the tensile strength for these particles.Ministerio de Ciencia e Innovación (MICINN)Depto. de Física de la Tierra y AstrofísicaFac. de Ciencias FísicasTRUEpu

No full textFoi determinada a eficiência de um recheio estruturado, disponível no Brasil com o nome comercial Mellapak 500 Y, em uma coluna de destilação piloto de diâmetro interno de 106 mm e altura efetiva de recheio de 5,2 m. Foram levantados os perfis de concentração de ambas as fases ao longo da coluna, pela amostragem em seis pontos diferentes, com a coluna operando na faixa de pressão de 315 mmhg a 416mmhg, e processando duas terebintinas com composições diferentes e uma mistura binária de \'ALFA\' e \'BETA\' pinenos. As eficiências foram calculadas a partir dos perfis de concentrações obtidas experimentalmente, com taxa de refluxo de 2,9 a 13,0, e total, e vazão de refluxo de 4,3 kg/h a 30,1 kg/h. O fator de capacidade do vapor variou entre 0,14 e 0,8 m\'POT.-1/2\'kg\'POT.1/2\'s\'POT.-1\' e os resultados dos cálculos do número de pratos teóricos por metro de recheio estão entre 3,5 e 4,5. A eficiência teórica calculada por um programa de computador, baseado em um modelo de transferência de massa recentemente desenvolvido em termos da geometria do recheio e das propriedades das fases (Billet; Schultes, 1993) foi comparada com a eficiência experimental obtida na operação da coluna recheada. O produto usado nos testes foi a terebintina, uma mistura de compostos terpenicos disponível na região, tendo interesse econômico a separação dos seus componentes por destilação.The regular packing marked in Brazil under the trade name Mellapak 500Y was studied to calculate its efficiency, using a pilot plant distillation column of 106mm inside diameter and 5,2m of effective packing height. Concentration profiles were measured by sampling both liquid and vapor in six positions along the column, over a pressure range of 315 to 416mmHg, with the test mixture turpentine of two differents compositions and a binary mixture of alpha and bets pinenes. Efficiencies were calculated from the experimental concentration profiles with vapor capacity factorvarying from 0.14 to 0.8 m-1/2kg1/2s-1, reflux ratio between 2.9 and 13.0, and total, and reflux flowrate of 4.3 to 30.1 kg/h. The number of theoretical plate per meter is in the range of 3.5 to 4.5. The efficiencies calculated by a computer program based on a recent mass transfer model described in terms of packing geometry and phases properties (Billet; Schultes, 1993) were compared with the experimental efficiencies from the packed distillation column. The test mixture used, the turpentime, is a regional multicomponent product with economical interest in separating their components by distillation. It was made the identification of eight main components of this mixture, each of then with a specif application as raw material for pharmaceutical, perfum and general chemistry industries. The experimental data Will be useful as support for the development of turpentine distillation plants

No full textApesar de seu desenvolvimento em anos recentes, a cristalização permanece essencialmente experimental. Este trabalho foi desenvolvido visando implantar a metodologia de obtenção dos parâmetros cinéticos em escala de laboratório no IPT S.A. Foi estudada a cristalização do ácido adípico em solução aquosa e em batelada, por resfriamento. O sistema consiste de um cristalizador com fundo em W, provido de agitador, banho de refrigeração e termômetro de imersão. Foram realizados quatro tipos de experimentos: sem semeadura com resfriamento linear e em curva exponencial e com semeadura e resfriamento linear e exponencial, sem o acompanhamento da supersaturação da solução. Os resultados do primeiro grupo foram utilizados na obtenção dos parâmetros cinéticos medios, a partir da distribuição granulométrica final. Considerando nulo o expoente da concentração mássica na nucleação foram obtidos os expoentes da supersaturação nas cinéticas de nucleação (n = 3,286) e crescimento (g = 1,571) e a constante cinética do sistema (\'B IND.N\' = 2,24 \'10 POT.-12\' em s i). Utilizando-os na previsão do tamanho medio final para os quatro grupos, foram obtidos erros absolutos, medio de 4,6% e máximo de 14,3%. Fotos por microscopia eletrônica indicaram que os cristais de ácido adípico sofrem forte aglomeração, que influe significativamente na sua qualidade.Crystallization technology has had a strong development in recent years but still nowadays it is an essencially experimental technology. This work aimed at estabilishing a methodology to obtain kinetic parameters in laboratory scale at IPT S.A. Adipic acid batch cooling crystallization was studied. The system consists of a \"W\' shaped bottom crystalizer, equipped with an agitator, cooling system and thermometer. Four groups of experiments were done: with and without seeds, and linear and exponential cooling curve. Supersaturation was not monitored during batch time. The experiments with linear cooling and no seeding were used to obtain kinetic parameters. Considering the exponent of mass concentration as zero, results on the supersaturation exponents for nucleation (n = 3.286) and growth (g= 1.571) as well as system constant (BN = 2.24 10 -12 in S.1. units) were obtained. These parameters were used to calculate mean crystal size in others groups of experiments, resulting in an average relative deviation of 4.60% and a maximum of 14,3%. Electron microscopy analysis revealed that adipic acid crystals have strong agglomeration tendency, wich strongly influences product quality

No full textFoi desenvolvido um modelo matemático do processo de extração de amônia do gás de coqueria por absorção com água usado na Companhia Siderurgica Paulista (COSIPA), com o objetivo de otimizar esse processo. Os equipamentos principais do processo são duas torres (A e B) de absorção recheadas, iguais, de quatro metros de diâmetro. Cada torre consta de quatro estágios, com recheio estruturado constituído de chapas de aço carbono perfurados e de inclinação definida. Nas condições nominais de projeto devem ser processados 67.000 metros cúbicos (CNPT) por hora de gás (para reduzir o teor de amônia de 6,22 a 0,06 gramas por metro cúbico de gás), com uma vazão de 30 metros cúbicos por hora de água tratada na torre a e uma alimentação lateral adicional de 21 metros cúbicos por hora de água amoniacal na torre B. O modelo é baseado em estágios de equilíbrio corrigidos pela eficiência, sendo adotado o método SR na resolução das equações. Foi desenvolvido o programa ABSAM, através do qual foi comprovada a validade do modelo por comparação com valores reais. Foram simuladas diversas condições operacionais para otimizar o processo. As modificações no processo sugeridas pela otimização permitem prever uma economia de 775.000 dolares por ano e de 720 metros cúbicos por dia de água potável.The main objective of this work was to develop a mathematical model that permit to find the best operational conditions related to extraction of ammonia, from the coke oven gas , by absorption with water.

ICTを活用した子ども・子育て支援の経験が保育学生に与える教育効果
No full text子ども子育て支援に対応できる保育者が求められている。ところが， 保育学生であっても乳幼児との関わり経験は乏しく， ましてや養育者とは殆ど関わった経験が無いというのが実状である。この課題は， 幼稚園・保育園実習においても解消されていない。そこで， 筆者らは2017年度から対面形式による親子支援を実践し， 並行して保育学生を支援者として養成してきた。2020年度からはコロナ禍によってICTを積極的に利活用したプログラムに切り替えたところ， 却って養育者と学生との関わりが質的・量的に改善され， 多様な家族への理解や学年を越えた学生間の協働など教育効果が得られた。なお， 本稿は2回の学会発表の内容を基に加筆修整している
