Maniaque-Benton, Caroline. "Les architectes français et la contre-culture nord-américaine : 1960-1975". Paris 8, 2006. http://octaviana.fr/document/168100886#?c=0&m=0&s=0&cv=0.
Testo completoBased on the notion of cultural transference and reception theory, the aim of the research is to follow the changing preoccupations of French architects with North America between 1960 and 1975 in the course of study trips or through periodicals and books. This was the period of the rise and fall of the counter culture in America. The mid-point of the period is the intellectual and cultural crisis of May 1968, in the United States as well as in France. The thesis documents the architects’ perception of professional and university cultures on the one hand and the counter culture on the other. The work concludes by tracing the impact of these lived experiences on the institutionalization of architectural research, the development of architectural education and methods of construction in France. A connected history of France and North America, the thesis does not restrict itself to national perspectives but focuses on the relationships between the two cultures
Chaljub, Bénédicte. "Les oeuvres des architectes Jean Renaudie et Renée Gailhoustet, 1958-1998 : théorie et pratique". Paris 8, 2007. http://octaviana.fr/document/134096258#?c=0&m=0&s=0&cv=0.
Testo completoThe object of this thesis is to enlight the works of two french architects Renée Gailhoustet (born in 1929) and Jean Renaudie (1925 - 1981), both of them with their own office. Their works concern urban programs grouping community facilities and public housing, with a particular interest for their adjacent realisations in Ivry-sur-Seine's downtown renovation, near Paris. Gailhoustet considers herself as a "follower" and gives to Renaudie a tutelary role, especially after his premature death while aknowledgement for his work is at his highest. The analysis of this conscious and accepted architectural filiation points out the quality and the originality of Gailhoustet's work, too often left in the master's shadow. By focusing specifically upon process of transmission and traduction between those two architects, the present work wishes to contribute to the debate around the notion of architectural model and to enlight the relation between architectural theory and practice

This study went on the medical aspects in socratic action, by following part of the platonic opera combined with twentieth century specialists that have explored the field of science in Plato, remarkably showing his attention towards medical arts of his contemporanity. Moving forward to Epictetus, Galen and Sextus, and back to Empedocles and Zeno from Eleia, the search for medicine in the platonic Socrates concerns altogether with that one on minimum Socrates, spread among these authors, that reveals as most significant characteristics either a fisicality that remains although the supposed abdication in favor of the concepts, and related do pratical ativities, as well as a special kind of visuality attained to discourse, that together seems to make singularly plausible that method of him. In connection to this, Epictetus and Empedocles let us know a negative skeptical conception related to natural sepsis and to peptical assimilation, exposing thus the words of the eps theme, in parallel to their respective prevalent aspects of negative skepticism, induced sepsis and noetical assimilation. This connection, seeming now surprisingly, ensures that one between the logical-discursive medium usually associated to philosophy and the experimental one equally usually associated to medicine. Plato operates on technical words from crafts doing operatory terms with properly philosophical character, enabled and activated to use in notions such as homoi?sis, analogy assimilation and others, upon a variety of themes, beyond a political-clinical attitude compromised with man-city unity in such a clinical enterprise, that debates with and encloses resources from the peste, war, and theatrological drama, worlds for whose transitions into the third century shows himself as a major catalizer through Socratic attitude. Methodical insistance on visuality provides the the following and reellaboration of Zeno arguments, of skema generalized notion, of a convenient proximity of c?tharsis to refutation and anamnesis, of empedoclitian conception of negative skepticism connected to natural sepsis that make summing to skopic distinction, as rethorical and skeptic, the positive skeptical division of unexamined humours and gases, now diagnostical.
Investigamos as caracter?sticas m?dicas na a??o socr?tica, seguindo parte da obra plat?nica e recorrendo a especialistas que ao longo do s?culo XX exploraram o campo novo da ci?ncia em Plat?o, notadamente seu acompanhamento atento ? arte m?dica de sua contemporaneidade. Com avan?os a Epiteto, Galeno e Sexto Emp?rico, e retornos a Emp?docles e Zen?o de El?ia, a pesquisa pela medicina no S?crates plat?nico coincide em parte com a pesquisa pelo S?crates m?nimo, espalhado no seu m?todo por estes autores que revelam como caracter?sticas principais uma fisicalidade permanente ? suposta abdica??o em favor do estudo do conceito e relacionada ?s pr?ticas dos of?cios, bem como uma visualidade especial ligada ao discurso, que numa composi??o singular parecem tornar seu m?todo cl?nico fact?vel. Em conex?o, Epiteto e Emp?docles fazem perceber uma concep??o de ceticismo positivo que se relaciona ? sepse natural e ? assimila??o p?ptica, expondo as palavras deste mesmo tema ?ps, em paralelo a seus respectivos aspectos prevalentes de ceticismo negativo, sepse induzida e assimila??o no?tica. Esse v?nculo, agora surpreendente, garante a conex?o entre o meio l?gico-discursivo usualmente associado ? filosofia e o meio experimental usualmente associados ? medicina. Plat?o opera sobre os jarg?es t?cnicos dos of?cios fazendo termos operat?rios de car?ter propriamente filos?fico, aptos e ativados para aplica??o de no??es como homoi?sis, assimila??o por analogia, e outras, sobre uma diversidade de temas, dentro de atitude pol?tico-diagn?stica comprometida com o par homem-cidade numa empreita cl?nica, que debate e incorpora recursos da guerra, da peste e da trag?dia, ?mbitos para cujas transi??es ao quarto s?culo ele se mostra um principal catalizador atrav?s da a??o socr?tica. O investimento met?dico na visualidade enseja o acompanhamento e reelabora??o dos argumentos de Zen?o, da no??o generalizada de esquema, de uma conveni?ncia da c?tharsis concomitante ? refuta??o e anamnese, da concep??o empedocl?tica de ceticismo negativo ligado ? sepse natural que faz somar ? distin??o esc?pica, antes ret?rica e c?tica, a divis?o s?ptica positiva dos humores e ventos inexaminados, agora diagn?stica.

Testo completoThis report is produced to document the existing installation regarding the ballast, bilge and fire system aboard the vessel M/S Calmare Nyckel. According to the specifications of the assignment a proposal regarding improvements will also be presented. The suggestions are mainly based on data from a supplier of valve components and the demands put up by the classification society. The improvements are considered with reduced risk and increased safety in mind. The main differences in the new proposals are the separation of the bilge system from the other two systems, that the most vital functions can be remote-controlled by pneumatics and that all components are marked according to industry standard.

Testo completo
Vi tilldelades detta projektet av Kalmar Sjöfartshögskola. Projektet var att tillverka en bullerkarta för skolfartyget M/S Calmare Nyckel. Då skolfartyget inte överskrider 500 bruttoton krävs ej en bullerkarta enligt Sjöfartsverket, men det fanns en förfrågan och önskan från skolan att tillverka en för utbildningssyfte och få en praktisk anknytning. Vid dem mätningarna som krävdes ombord rättade vi oss efter ISO 2923:1996(E) samt Sjöfartsverkets författningssamling 2005:23 vid tillverkning av bullerkartan. Skolan tillhandahöll oss med godkänd mätutrustning samt mätprotokoll. Vi fick ett bra tillfälle att göra samtliga mätningar när skolfartyget gjorde sin sjöresa från Simrishamns varv till Kalmar, med goda väderförhållanden och samtliga maskiner i normala driftsförhållanden. Resultaten blev en lättförstådd och användarvänlig bullerkarta i A4 format som kan anslås varsomhelst på fartyget eller användas i utbildningssyfte.
We were assign this project by Kalmar maritime academy. The project was to produce a noise map for the school boat M/S Calmare Nyckel. The school boat does not exceed 500 dead weight ton and is not required a noise map according to national maritime administration, but there was an request and desire from the school to produce it for education purpose and for a practical connection. For the measurements that were required on board we used the regulations from ISO 2923:1996 (E), and national maritime administration's statute book 2005:23 with production of the noise map. The school provided us with validated measuring equipment and measuring protocol. We had a good opportunity to do all measurements when the school boat did its sea travel from Simrishamn's shipyard to Kalmar, with good weather conditions and all machines in normal operation conditions. The results became a easy understood and friendly used noise map in A4 formats that can be assigned anywhere on the boat or to be used in education purpose.

Testo completoM/S Calmare Nyckel är sjöfartshögskolans skolfartyg och nyttjas för att bedriva utbildning på både
det Nautiska- och det Maskintekniska planet.
För att kunna bedriva en högkvalitativ och realistisk utbildning ombord på fartyget krävs det
att utrustningen ombord återspeglar en modern verklighet. Vårat arbete har varit inriktat mot att
förbereda installation av ett datorbaserat maskinövervakning och larmsystem. Dessutom komplettering
av redan befintligt ritningsunderlag.
Under arbetets gång har vi testat samtliga larmpunkter enligt upprättad larmlista och då konstaterat
allvarliga brister i det befintliga maskinlarmsystemet. Detta fick till följd att arbetet ändrade
karaktär och utökades något.
Resultatet av vårat arbete ombord på M/S Calmare Nyckel har mynnat ut i ett fungerande
maskinlarmsystem samt goda förutsättningar för vidare installation av datorbaserad maskinövervakning
och larmsystem.
Dokumentation över installerat system finns som bilaga till denna avhandling. Fartyget har
dessutom erhållit kopia av denna dokumentation.
Vi hoppas att denna avhandling kan vara till hjälp för kommande arbeten inom samma område.

Testo completoOur goal has been to develop an Emergency Towing Manual for the scholar ship M/S Calmare Nyckel. It would be in line with present rules and conventions and facilitate decision-making in situations requiring emergency towing. Our project client is Bengt Carlsson, Master on the Calmare Nyckel, and after intitial talks the work was set in motion taking form of a project.The Emergency Towing Manual is foremost based upon present legislation and guidelines but also on other ships ETM:s, which we have found succesfull.The project was carried out within our schedule and the resulting manual was well appreciated by us and the project client.M/S Calmare Nyckel is now equipped with a fully functioning Emergency Towing Manual which meets all applicable demands. Our hope is that the manual will never have to be used during real emergencies – however, regularly refered to in exercises as part of the onboard emergency prepardness.

Testo completoA hotel building in the town of Mariefred. Examines the room created in the gap between smaller heavier volumes, where hotel rooms and other private programs are placed. A hotel is located in one city but populated by people from another. You have probably never been to the hotel located where you live, but the number of hotels visited in other cities and countries are several. The typical swedish cityhotel from the early 20th century that served as a meeting place for locals is now difficult to find. In this project, main focus has been on the locals and towards Mariefred. Visitors will come here anyway? The house serves as a meeting place between people from Mariefred, but of course also for tourists and hotel guests. The hotel also acts as a link between the castle of Gripsholm and Mariefred city. Something between the big city and the small visitor. With the hotel's position as a portal to the city, it summarizes the town of brick, wood, large, small, people from Mariefred and tourists. S, M, L symbolizes thus the small, the great and the hotel in between.

Testo completoLa valeur ?vocative, magique ou my(s)thique attribu?e ? la relation homme/animal peut ?tre observ?e dans la culture depuis les ?poques lointaines. Dans la symbologie animale on trouve une immense charge s?mantique justifiant les croyances les plus anciennes que les ?tres humains ont d?j? eues. Les animaux sont ? la base du symbolisme mythique et ils se constituent en tant qu une source pour la riche production artistique englobant une grande vari?t? iconographique et des textes de nature diverse. Ayant comme r?f?rence de la symbologie animal l image my(s)thique du chat, on observe la fa?on par laquelle le langage po?tique contemple les profils mythiquesymboliques qui ont un rapport avec ce langage, tout en mettant en relief ceux qui ont des rapports aux relations entre le monde humain et le f?lin. ? partir de l antologie t?matique Assinar a pele ; des concepts th?oriques ; et des abordages mitocritiques, nous cherchons ? analyser les fa?ons par lesquelles les diff?rentes images mythiques associ?es au chat ont ?t? explor?es par la po?sie. La d?finition d une typologie englobant des cat?gories telles : chat domestique, chat de rue, chat femme, chat nocturne, chat d?moniaque et chat divin, parmi d autres, soutient la reconnaissance d identit?s possibles entre ces po?mes et signale la r?p?tition d un r?pertoire symbolique divers en soi, mais, coh?rent avec la pr?sence du chat dans la soci?t? humaine ? travers les temps
O valor evocativo, m?gico ou m?(s)tico atribu?do ? rela??o homem/animal pode ser observado na cultura desde ?pocas remotas. Na simbologia animal encontra-se imensa carga sem?ntica, fundamentando as cren?as mais antigas que os seres humanos j? tiveram. Os animais est?o na base do simbolismo m?tico e constituem fonte para rica produ??o art?stica, englobando grande variedade iconogr?fica e textos de natureza diversa. Tomando como refer?ncia da simbologia animal a imagem m?(s)tica do gato, observamos como a linguagem po?tica contempla os perfis m?tico-simb?licos a ela relacionados, destacando aqueles que se referem ?s rela??es entre o mundo humano e o felino. A partir da antologia tem?tica Assinar a pele; de pressupostos te?ricos; e de abordagens mitocr?ticas, buscamos analisar como as diversas imagens m?(s)ticas associadas ao gato foram exploradas em algumas das muitas poesias acerca desse felino. A defini??o de uma tipologia que engloba categorias tais como: gato dom?stico, gato de rua, gato mulher, gato noturno, gato demon?aco e gato divino, entre outras, sustenta o reconhecimento de identidades poss?veis entre esses poemas e assinala a recorr?ncia de um repert?rio simb?lico diverso em si mesmo, mas, de outro lado, coerente com a presen?a do gato na sociedade humana atrav?s dos tempos

This study aimed to assess factors associated with nipple trauma in women who breastfeed, resulting in two articles. The first entitled "Factors associated with nipple trauma in lactation period: a systematic review" was based on the search of publications indexed in the databases Medical Literature Analysis and Retrieval System Online/Pubmed, Latin American and Caribbean Health Sciences, and ScienceDirect, with no restriction on language or publication period. As risk factors for nipple trauma were identified: mother with white or yellow race/color, primiparity, cracked nipples in previous pregnancies, mother who does not live with a partner, use of anesthesia in parturition, gestational age of the newborn between 37 to 40 weeks, presence of breastfeeding in the first hour of life, semi protrude and/or malformed nipples, malposition between mother and child, incorrect lacth of the infant in mother's breast, presence of breast engorgement, nipple pain, use of nursing bottle, use of pacifier and lactational mastitis. On the other hand, the guidance received about how to lacth and positioning the infant in the maternal breast during prenatal was considered as a protective factor against the nipple trauma. The second article entitled "Nipple fissure: study of latent variables in the first month postpartum" consisted of a cross-sectional analysis of a birth cohort, an observational and prospective character, who studied the mother-child dyad. The prevalence of cracked nipples observed in mothers who breastfeed in the first month postpartum was 35.9%. It was found among the latent variables that the unfavorable maternal emotional state (OR= 1.65; 95% CI= 1.26-2.16) and lower availability for breastfeeding (OR= 1.80; 95% CI= 1.25-2.59) were associated with cracked nipples, as well as the covariates parturition in unit that is not recognized as a Baby Friendly Hospital (OR= 1.48; 95% CI= 1.07-2.03), cesarean section (OR= 1.72; 95% CI= 1.33-2.24) inadequate positioning of the newborn during breastfeeding (OR= 3.91; 95% CI= 1.02-14.99), incorrect lacth of the infant the in the maternal breast (OR= 14.36; 95% CI= 7.80-26.46) and the presence of breast engorgement (OR= 2.74; 95% CI= 2.10-3.58). Preventive measures against the risk factors of nipple trauma are necessary to prevent this important cause of pain during breastfeeding and premature weaning.
Este estudo teve como objetivo avaliar os fatores associados ao trauma mamilar em lactantes, tendo como resultado dois artigos. O primeiro intitulado ?Fatores associados ao trauma mamilar no per?odo lactacional: uma revis?o sistem?tica? foi fundamentado na busca de publica??es indexadas nas bases de dados Medical Literature Analysis and Retrieval System Online/Pubmed, Literatura Latino-Americana e do Caribe em Ci?ncias da Sa?de, e ScienceDirect, sem restri??o de idioma ou per?odo de publica??o. Foram identificados como fatores de risco para o trauma mamilar: m?e de ra?a/cor branca ou amarela, primiparidade, presen?a de fissura mamilar em gesta??es anteriores, m?e n?o residir com o companheiro, uso de anestesia no parto, idade gestacional do rec?m-nascido entre 37e 40 semanas, presen?a de mamada na primeira hora de vida, mamilos semiprotrusos e/ou mal formados, posicionamento inadequado entre m?e e filho, pega incorreta do lactente ao seio materno, presen?a de ingurgitamento mam?rio, dor mamilar, uso de mamadeira, uso de chupeta e mastite lactacional. Por outro lado, a orienta??o recebida sobre pega e posicionamento do lactente ao seio materno durante o pr?-natal foi considerada como fator de prote??o contra o trauma mamilar. O segundo artigo intitulado ?Fissura mamilar: estudo de vari?veis latentes no primeiro m?s p?s-parto? consistiu em uma an?lise transversal de uma coorte de nascidos vivos, de car?ter observacional e prospectiva, que estudou a d?ade m?e-filho. A preval?ncia de fissura mamilar observada em lactantes no primeiro m?s p?s-parto foi de 35.9%. Verificou-se entre as vari?veis latentes que o estado emocional materno desfavor?vel (OR= 1.65; IC 95%= 1.26-2.16) e menor disponibilidade para amamentar (OR= 1.80; IC 95%= 1.25-2.59) associaram-se ? fissura mamilar, assim como as covari?veis parto em unidade n?o credenciada como Hospital Amigo da Crian?a (OR= 1.48; IC 95%= 1.07-2.03), parto ces?reo (OR= 1.72; IC 95%= 1.33-2.24), posicionamento inadequado do neonato durante a mamada (OR= 3.91; IC 95%= 1.02-14.99), pega incorreta do lactente ao seio materno (OR= 14.36; IC 95%= 7.80-26.46) e presen?a de ingurgitamento mam?rio (OR= 2.74; IC 95%= 2.10-3.58). A??es de preven??o contra os fatores de risco do trauma mamilar s?o necess?rias para evitar esta importante causa de dor durante a mamada e de desmame precoce.

Testo completoThis diploma thesis was made for working out the pro and cons of installing a variable-frequency drive for the sea-water pumps on the ship m/s Finnfellow. The main object of the work was to give the chief engineer of the ship a foundation on which he could decide if it is worth installing this or not. The main investigation in the work was to find out how the variable-frequency drive would affect the sea-water system. The result of the work was that a considerable amount of electrical energy could be saved yearly (122MWh). This would mean that the installation cost could be repaid in fewer than 2 years with the current fuel prices, also an environmental advantage was discovered because the ship would consume 26 tons of fuel oil less each year. The conclusion of the work is that it would be very beneficial to have a variable-frequency drive onboard.

In this work it was synthesized and characterized the cobalt ferrite (CoFe2O4) by two methods: complexation combining EDTA/Citrate and hydrothermal investigating the influence of the synthesis conditions on phase formation and on the crystallite size. The powders were mainly characterized by x-ray diffraction. In specific cases, it was also used scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), x-ray fluorescence (XRF) and isotherms of adsorption and desorption of nitrogen (BET method). The study of the crystallite size was based on the interpretation of x-ray diffractograms obtained and estimated by the method of Halder-Wagner-Scherrer and Langford. An experimental design was made in order to assist in quantifying the influence of synthesis conditions on the response variables. The synthesis parameters evaluated in this study were: pH of the reaction medium (8, 9 and 10), the calcination temperature (combined complexation method EDTA/Citrate 600?C, 800?C and 1000?C), synthesis temperature (hydrothermal method 120?C, 140?C and 160?C), calcination time (combined complexation method EDTA/Citrate - 2, 4 and 6 hours) and time of synthesis (hydrothermal method 6, 15 and 24 hours). By the hydrothermal method was possible to produce mesoporous powders with high purity, with an average crystallite size up to 7 nm, with a surface area of 113.44 m?/g in the form of pellets with irregular morphology. By using the method of combined complexation EDTA/Citrate, mesoporous powders were produced with greater purity, crystallite size up to 22nm and 27.95 m?/g of surface area in the form of pellets with a regular morphology of plaques. In the experimental design was found that the hydrothermal method to all the studied parameters (pH, temperature and time) have significant effect on the crystallite size, while to the combined complexation method EDTA/Citrate, only temperature and time were significant
Neste trabalho foi sintetizada e caracterizada a ferrita de cobalto (CoFe2O4) atrav?s dos m?todos complexa??o combinada EDTA/Citrato e hidrot?rmico, investigando a influ?ncia das condi??es de s?ntese na forma??o da fase e no tamanho m?dio de cristalito. Os p?s foram caracterizados principalmente por difra??o de raios-x. Em casos espec?ficos, tamb?m foi utilizado microscopia eletr?nica de varredura (MEV), espectroscopia de energia dispersiva (EDS), fluoresc?ncia de raios-x (FRX) e isotermas de adsor??o e dessor??o de nitrog?nio (M?todo BET). O estudo do tamanho de cristalito foi baseado na interpreta??o dos difratogramas de raios-x obtidos e estimado atrav?s do m?todo de Halder-Wagner-Langford (HWL) e de Scherrer. Um planejamento experimental foi realizado com a finalidade de auxiliar na quantifica??o da influ?ncia das condi??es de s?ntese nas vari?veis-resposta. Os par?metros de s?ntese avaliados neste trabalho foram: pH do meio reacional (8, 9 e 10), temperatura de calcina??o (m?todo de complexa??o combinando EDTA/Citrato 600?C, 800?C e 1000?C), temperatura de s?ntese (m?todo hidrot?rmico 120?C, 140?C e 160?C), tempo de calcina??o (m?todo de complexa??o combinando EDTA/Citrato 2, 4 e 6 hrs) e tempo de s?ntese (m?todo hidrot?rmico 6, 15 e 24 hrs). Pelo m?todo hidrot?rmico foi poss?vel produzir p?s mesoporosos com elevado grau de pureza, com tamanho m?dio de cristalito de at? 7nm, com ?rea superficial de 113,44m?/g e na forma de aglomerados com morfologia irregular. Ao se utilizar o m?todo de complexa??o combinando EDTA/Citrato foram produzidos p?s mesoporosos com maior pureza, cristalitos com at? 22nm de tamanho, 27,95m?/g de ?rea superficial e na forma de aglomerados com morfologia regular de placas. No planejamento experimental foi constatado que no caso do m?todo hidrot?rmico todos os par?metros estudados (pH, Temperatura e tempo) apresentam efeito significativo no tamanho de cristalito, enquanto que, para o m?todo de complexa??o combinando EDTA/Citrato, apenas a temperatura e o tempo foram significativos

Testo completoConcrete is one of the most widely used building materials in the world. Durability, mechanical and chemical properties have made it a material of choice in storage concepts proposed by the French National Agency for Radioactive Waste Management (Andra), including the achievement of retaining structures, cell plugs, massive supports or conditioning waste. The study of the stability of the constituent phases of cementitious materials is needed in view of the planned quantities and the durability of the structures, andmust consider (i) temperature ranges suitable for cement matrices containment in contact with exothermic waste (25-80°C), and (ii) a representative time scale of the lifetime of the storage.The Andra ThermoChimie project therefore aims to develop a consistent thermodynamic database, to model the chemical evolution of cement materials in the environment of radioactive waste. However, in the present state, the database offers only thermodynamic data of cementitious crystalline phases, as well as a limited data set of three different chemical compositions for nanocrystalline C-S-H. This does not allow to reproduce the degradation of cementitious materials, or model the degradation of the new formulations, such as "Low pH" concretes.The objective is therefore to acquire a thermodynamic complementary data set on phases such as C-S-H (Calcium Silicate Hydrates) C-A-S-H (Calcium Aluminate Silicate Hydrates) and M-S-H (Magnesium Silicate Hydrates), to complete the ThermoChimie database. This study is based on experimental, analytical and digital work, in order to obtain a set of thermodynamic data (ΔfG0, ΔfH0, Cp(T), S0) sufficiently representative of the chemical variability of these phases. Finally, this set of data allows the development of a thermodynamic predictive model in extended spaces of compositions and temperatures.Development of this predictive model requires (i) The acquisition of thermodynamic properties on representative phases of the studied chemical system, and (ii) a precise knowledge of the structure and chemical formulas of these phases. Three types of hydrates were therefore synthesized and characterized: C-S-H, C-A-S-H and M-S-H. Analytical methods such as XRD, TGA and solid state NMR (29Si, 27Al) are used to ascertain similarities between the structure of C-(A-)S-H and that of tobermorite, and between the structure of M-S-H and that of Mg-Si phyllosilicates 2:1. Hydrates, however, have a lower crystallinity, with defects in the polymerization of silica chains, and random stacking faults (turbostratism).A multi-technique approach is also used, combining adsorption isotherm (water and nitrogen) and 1HNMR with XRDand TGA, and allows characterization of different types of water more or less bound to the structure of C-(A-)S-H.This study allowed to highlight and quantify the different types of water in the C-(A-)S-H structure. The impact of the drying process was also highlighted on the quantification of different types of water, including interlayer water. The acquisition of thermodynamic parameters of the synthesized phases is carried out from the analysis of equilibrium solutions for the calculation of log K and ΔfG0, while calorimetric acquisitions permit obtaining heat capacities and the calculation of S0. Finally, enthalpy of formation of these phases is calculated from the Gibbs free energy of formation and entropies.The predictive model is developed fromthe acquired thermodynamic properties.The Gibbs free energy of formation ΔfG0 is predicted from an electronegativity model, while Cp and S0 are predicted through polyhedral decomposition model. Finally, a comparison of data obtained with those published in the literature, and the realization of predominance diagrams generalized to the whole CaO-MgO-Al2O3-SiO2-H2O system assess the reliability of the proposed model

Testo completoIt is possible to make a stereophonic recording of a musical ensemble performing live in a studio with a pair of good quality microphones in order to obtain an audio document close to reality. May we then call it a « perfect » recording? In fact, sonic problems and mistakes can still be part of the document and will be much difficult to correct, all elements being tied as a virtually unbreakable entity. On the other hand, we could use technology to record the elements individually, correct them separately and mix them afterwards. In this case, we need to take artificial ways to recreate position of the instruments in the band and make them appear in the sonic ambience of a real performance venue. The Superimposed M/S Layering method for recording and mixing music optimizes the pros of those two « classical » methods of studio production, while minimising their cons. It consists in recording each element of the musical ensemble in isolation in the studio live room and occupying its usual place in the ensemble. We record it with a Middle-Side array of microphone, a device that can reproduce with great conformity the position, spread and reverberation of a sound source in a stereophonic layer. Then, stacking all the layers of the instruments, we can recreate the whole ensemble as if it had performed live, but with complete control over sonic characteristics of each instrument and over its contribution to the ensemble.

Testo completoMålet med denna uppsats är att ta reda på hur solceller kan förbättra energieffektiviteten ombord M/S Sydfart. Uppsatsen baseras på ett antal energimätningar ombord M/S Sydfart. Solcellernas yta beräknas med hänsyn taget till tillgänglig yta för att installera solpaneler. Globalstrålningsdata kommer ifrån STRÅNG`s databas, den datan används sedan för att beräkna en teoretisk producerad effekt utav solcellerna. Energieffektiviteten analyseras på två sätt. Den första analysen ser på hur mycket av den dagliga energiförbrukningen som kan tillgodogöras med solceller. Den andra analysen baseras på hur stor för- ändring av EEOI som kan uppnås med installerade solceller. Elenergibehovet ombord M/S Sydfart, under sommarhalvåret, kan nästan helt täckas med solceller. Uppsatsen visar dock en del nackdelar med solceller. Under vinterhalvåret är den producerade elenergin från solcellerna låg och en orimligt stor yta solcellsmoduler behövs för att täcka elenergibehovet. Två scenarion utvärderas. I scenario ett utnyttjas all tillgänglig yta för installation av solcellsmoduler. Detta ger ett stort energiöverskott på sommarhalvåret. I scenario två halveras ytan för solcellsmoduler och energiöverskottet blir då mindre. Med hänsyn till att M/S Sydfart har begränsad möjlighet att ta till vara på energiöverskottet, rekommenderas scenario två. Resultatet visar att energieffektiviteten kommer att förbättras. Beroende på årstid, kan EEOI förbättras mellan 0.5% och 12 %. Något krav på förbättring av EEOI finns inte från IMO. Det är rederierna själva som sätter upp interna mål för förbättring.

Testo completoWe study approximations for performance measures of call centers, represented by M/G/s/r+G queueing model. We use the measures computed in the M/M/s/r+M(n) queueing model. The results were extended for more then one type of customer, represented by M/Mi/s/r+Mi(n) queueing model. For two particular cases with two types of customers, the mentioned approaches were numerically evaluated and compared with the results of reference obtained by simulation. The approximate results show that the approach is quite satisfactory.

L??tude enqu?te la place occup?e par les m?dias dans la construction de l?identit? des artistes qui font partie du circuit culturel de la musique sertaneja ? S?o Lu?s. Cette recherche est bas?e sur deux propositions: d?abord, que la musique constitue un proc?s communicatif qui s??tablit dans l?articulation entre les artistes, les m?dias et les consommateurs; en second lieu, que la production de sens ? travers la musique est impliqu?e par la classification attribu?e par les genres musicaux. Les genres, en ce sens, font partie d?une strat?gie d?adressage, agissant par des aspects qui les constituent: la sonorit? et la performance. La recherche a un int?r?t sp?cifique par la musique sertaneja, genre dont l?origine remonte ? la fin des an?es 1920. Ce genre a subi de profondes transformations au cours du temps et s?est fix? dans la capital maranhense en fonction des d?placements li?s ? l?immigration et de la diffusion m?diatique. Par l?adoption d?une m?thodologie inspir?e par l?ethnographie, cette recherche refl?te l?articulation qui existe entre les moments qui composent le circuit culturel mentionn?: l?identit?, la representation, la production, la consommation et la regulation. Il est conclu que les m?dias joue un role crucial dans la formation de l?identit? des chanteurs sertanejos qui forment le sc?nario analys?.
O estudo investiga o lugar ocupado pela m?dia na constru??o da identidade dos artistas que comp?em o circuito cultural da m?sica sertaneja em S?o Lu?s. Esta busca est? baseada em duas proposi??es: primeiro, que a m?sica constitui um processo comunicativo que se estabelece na articula??o entre os artistas, a m?dia e os consumidores; em segundo lugar, que a produ??o de sentido atrav?s da m?sica est? implicada pela classifica??o atribu?da pelos g?neros musicais. Os g?neros, nesse sentido, fazem parte de uma estrat?gia de endere?amento, que atua por meio dos aspectos que os constituem: a sonoridade e a performance. A pesquisa tem um interesse particular pela m?sica sertaneja, g?nero cuja origem remonta ao final da d?cada de 1920. Esse g?nero passou por profundas transforma??es ao longo do tempo e se fixou na capital maranhense em fun??o dos deslocamentos decorrentes da migra??o e da dissemina??o midi?tica. Por meio da ado??o de uma metodologia inspirada pela etnografia, esta investiga??o evidencia a articula??o existente entre os momentos que formam o circuito cultural mencionado: identidade, representa??o, produ??o, consumo e regula??o. Infere-se que a m?dia desempenha um papel central na forma??o da identidade dos cantores sertanejos que constituem o cen?rio analisado.

Testo completoBoth Lithuanian and Latvian prosaic creation work is being distinquished as breeding-grounds of unique litterateur generation in context of whole global literature. The Balts culture and its developing tendency forms were represented and overspread throughout a pecular literature in accordance with grievous historical experiences in these countries. While being fettered by the Soviet ideology, Lithuanian and Latvian prosaists tried not to alienate from the conception of valued art, so they have their ideological framework in requirements to disclose a misunderstanding human value system of the ‘real‘ Soviet regime. The latest time of 20th century in the Balts literature is defined as an uprise of prominent prosaists having their own trend-setting characters: Saulius Saltenis, Visvaldis Lamas and Margeris Zarinis. These authors are characterized as individuals with their new and modern approaches both into the same historical time and literature. In criticizing the ideological system of the Soviet regime, an unexpected search in expressive art system is being composed. The unreasonal viewpoints of the reality, human bust-ups, and changed standpoints into a personal self-image are being described by the authors with some methods of art expressions, i.e. grotesque and irony, as the ways of human resistance against the new regime and unallowed level. A Latvian writer V. Lamas it is noteworthy said to be the first prosaist whose description of a human existence and an... [to full text]

Testo completoThe objective of this study is a psycho-analytic investigation about mother s experiences with Down syndrome children. This research consists of individual open interviews with four different mothers. After each meeting, a psycho-analytic narrative with the goal to learn the fields of life-related psychology was recorded. In this context eventual behavior of overcoming dissociation becomes evident. Two fields were found: The loss of the perfect child and What s going to happen to my child once I am not there for him any longer? The outcome showed evidence that the mothers who were interviewed have developed different emotional survival strategies which helps them to maintain a special maternal pre-occupation for a long period of time.

Ap?s cada encontro, foram redigidas narrativas psicanal?ticas, visando apreender os campos psicol?gico-vivenciais, no contexto dos quais se tornam vis?veis eventuais movimentos de supera??o de dissocia??es. Foram encontrados dois campos: O desaparecimento do filho perfeito e O que ser? de meu filho quando eu n?o mais estiver aqui? . O quadro geral encontrado evidencia que as m?es entrevistadas desenvolveram estrat?gias de sobreviv?ncia emocional diversas, que lhes permitiu se manterem por um longo per?odo no estado de preocupa??o materna especial.

Testo completoThis work addresses the dynamic control problem of two-wheeled differentially driven non-holonomic mobile robot. Strategies for robot positioning control and robot orientating control are presented. Such strategies just require information about the robot con?guration (x, y and teta), which can be collected by an absolute positioning system. The strategies development is related to a change on the controlled variables for such systems, from x, y and teta to s (denoting the robot linear displacement) and teta, and makes use of the polar coordinates representation for the robot kinematic model. Thus, it is possible to obtain a linear representation for the mobile robot dynamic model and to develop such strategies. It is also presented that such strategies allow the use of linear controllers to solve the control problem. It is shown that there is flexibility to choice the linear controller (P, PI, PID, Model Matching techniques, others) to be implemented. This work presents an introduction to mobile robotics and their characteristics followed by the control strategies development and controllers design. Finally, simulated and experimental results are presented and commented
Esta disserta??o trata do problema de controle din?mico de rob?s m?veis n?o-holon?micos com duas rodas e acionamento diferencial. S?o apresentadas estrat?gias para controle de posi??o e de orienta??o de rob?s com as caracter?sticas citadas, baseadas apenas em informa??es de configura??o do rob? (posi??o e orienta??o no espa?o cartesiano x, y e teta), coletadas a partir de um sistema de posicionamento absoluto. O desenvolvimento da estrat?gia est? associado a uma mudan?a nas vari?veis controladas do rob?, de x, y e teta para s (representando o deslocamento linear do rob?) e teta, e na representa??o em coordenadas polares do modelo cinem?tico do rob?. Desta forma, consegue-se uma representa??o linear para o modelo din?mico do rob?, a partir da qual s?o propostas as estrat?gias de controle. Com as estrat?gias definidas, mostra-se que ? poss?vel implementar controladores din?micos lineares para permitir a estabiliza??o do sistema rob?tico. As estrat?gias apresentadas tamb?m fornecem flexibilidade com rela??o ? escolha do tipo de controlador din?mico (P, PI, PID, t?cnica Model Matching, entre outros) a ser utilizado.

Testo completoThe main task and one of the major mobile robotics problems is its navigation process. Conceptualy, this process means drive the robot from an initial position and orientation to a goal position and orientation, along an admissible path respecting the temporal and velocity constraints. This task must be accomplished by some subtasks like robot localization in the workspace, admissible path planning, trajectory generation and motion control. Moreover, autonomous wheeled mobile robots have kinematics constraints, also called nonholonomic constraints, that impose the robot can not move everywhere freely in its workspace, reducing the number of feasible paths between two distinct positions. This work mainly approaches the path planning and trajectory generation problems applied to wheeled mobile robots acting on a robot soccer environment. The major dificulty in this process is to find a smooth function that respects the imposed robot kinematic constraints. This work proposes a path generation strategy based on parametric polynomials of third degree for the 'x' and 'y' axis. The 'theta' orientation is derived from the 'y' and 'x' relations in such a way that the generated path respects the kinematic constraint. To execute the trajectory, this work also shows a simple control strategy acting on the robot linear and angular velocities
Um dos maiores problemas em rob?tica m?vel diz respeito ? sua navega??o. Conceitualmente, o ato de navegar em rob?tica consiste em guiar um rob? em um espa?o de trabalho durante um determinado intervalo de tempo, por um caminho que possa ser percorrido e que leve o rob? de uma posi??o e orienta??o iniciais para uma posi??o e orienta??o finais. Esta ? a principal tarefa que um rob? m?vel deve executar. Ela implica em subproblemas que s?o a localiza??o do rob? no espa?o de trabalho, o planejamento de um caminho admiss?vel, a gera??o de uma trajet?ria e, por fim, a sua execu??o. Al?m disso, rob?s m?veis aut?nomos com rodas possuem restri??es cinem?ticas, chamadas tamb?m de restri??es n?o-holon?micas, que fazem com que o rob? n?o possa se mover livremente em seu espa?o de trabalho, limitando a quantidade de caminhos admiss?veis entre duas posi??es distintas. Este trabalho aborda principalmente os subproblemas do planejamento de caminho e gera??o de trajet?ria aplicado a minirrob?s m?veis com rodas que atuam em um projeto de futebol de rob?s. O maior desafio para a navega??o destes ve?culos ? determinar uma fun??o cont?nua que respeite suas restri??es cinem?ticas e evolua no tempo segundo as restri??es impostas pelo problema quanto ? posi??o e orienta??o iniciais e finais e quanto ? velocidade do movimento. Prop?e-se uma estrat?gia de gera??o de caminho baseada em polin?mios param?tricos de terceiro grau em 'x' e 'y'. A orienta??o 'theta' do minirrob? ? obtida da rela??o entre 'y' e 'x' de modo que os caminhos gerados respeitem a restri??o cinem?tica imposta. Para que a trajet?ria seja executada e os resultados experimentais validados ? apresentada uma estrat?gia simples de controle que atua sobre as velocidades linear e angular desenvolvidas pelo rob? m?vel
