Mobile augmented reality has become an influential tool for digital content representation and visualization of media content in terms of enhancing users' experience and improving the adaptability and usability of typical augmented reality applications, such as in e-commerce shopping, virtual museum, or digital heritage scenarios. This research proposes a new Service Oriented Mobile AR Architecture called SOMARA, which includes a novel mobile AR client application. SOMARA takes advantage the ability to integrate third party content through service orientation. The SOMARA architecture enhances traditional standalone mobile AR applications with embedded media content by uniquely integrating a web service framework into an augmented reality client application to create more efficient and flexible mobile augmented reality applications that efficiently supports novel media content acquisition and visualization through appropriate access parameters. The proposed architecture requires access to media content through specific media content service providers, e.g. a museum commissioning an augmented reality based museum interactive — predetermined media content, or any third party with their own service APIs, e.g. the Victoria and Albert Museum API — related external media content. This approach allows relevant third party media content to be ‘mashed' via their public API with museums' augmented reality interactive's ‘embedded' media content in the SOMARA mobile AR client. In this way novel mobile AR interactive applications, such as a museum augmented reality interactive, can be created based on particular museum environment scenarios that integrate a museum visitor's experience with the interactive's cultural objects. Such experiences based on a SOMARA type museum augmented reality interactive can also be saved allowing visitors to take home their museum experience. SOMARA thus allows museum interactive experiences based on visualization of museums and third party media content physically located in the museum to be migrated to the visitor's home environment for further study, enjoyment and understanding. This unique feature, ability to effectively replay the experience at home, of the proposed system utilizes service-orientation to integrate third party media content, which is currently deficient from commercial augmented reality solutions.

This research examines the social use of the Internet at the level of specified online users in conservative Arab societies, who are called in this thesis online lead users. These specified lead users are the ones who are influential in shaping the innovation processes due to their leading role of practice in finding solutions to their needs and problems they have experienced before the emergence of online social networks such as the lack of public sphere and independent civic organizations etc., which led them to utilize the Internet as their new public space to pursue their goals through their online initiatives and collective actions to apply the social change they seek for their societies under the existence of society social norms and censorship. The research has been carried out as mixed-method study, the gathered data done through means of quantitative and qualitative methods, and the chosen country to conduct the research were Saudi Arabia. A survey questionnaire link were distributed among the targeted online lead users in the country under study, and the author chose three cases form the country under study for the qualitative part. The research sought to examine to what extent society social norms and censorship influence online lead user's expression and behaviours, and their effect on the formulation of their online activities and collective actions, and analyzing the characteristics of online lead user's. The significance of this study lies in the fact that it contribute to the gap in the literature on the use of Internet in conservative Arab societies by providing insight into the roles that social norms play in influencing online behaviour, particularly in communities that are seeking to discuss social issues or mobilize collective action, and analysing online lead users characteristic to distinguish between conservative and cosmopolitan ones using the Right-Wing authoritarian measurement.

O objetivo deste trabalho foi investigar, a partir da reforma das licenciaturas nas universidades ocorrida em 2001, a constituição do eixo disciplinar Prática como Componente Curricular (PCC) nos currículos de licenciatura de cursos de Letras, Português / Espanhol da região sudeste brasileira, focando-nos na relação entre teoria e prática. Para tal discussão, utilizamo-nos das reflexões de Deleuze (1968) a fim de problematizar as possibilidades de repetição total ou de diferenciação total; Vázquez (1977), ao trazer sua discussão de práxis que trata da indissociabilidade da teoria e da prática e Schwartz (2010), para incorporar a discussão sobre o âmbito do trabalho, em particular no que concerne a impossibilidade de antecipação completa da atividade a ser realizada por um profissional. Operamos, também, com os preceitos da Análise do Discurso de base enunciativa (MAINGUENEAU, 1998, 2003) quando tratamos os enunciados como socio-historicamente situados em nossas análises. Para atingirmos nosso fim, realizamos uma contextualização documental que contou com a análise do Parecer CNE/CP 28/2001, no qual estão as determinações sobre carga horária e definição dos eixos de disciplinas da licenciatura, sendo eles: Acadêmico Científico, Prática como Componente Curricular e Estágio Supervisionado. Voltamo-nos, também, para os Projetos Políticos Pedagógicos das universidades analisadas, a fim de investigar qual o entendimento de prática construído nesses documentos. Por fim, recorremos às ementas das disciplinas obrigatórias de PCC oferecidas pelas universidades que compuseram o córpus, buscando identificar as marcas que aproximam a temática da disciplina com o trabalho que considere a prática docente, já que o eixo em questão pressupõe essa discussão. Como critérios de seleção de córpus, consideramos: contemplar uma universidade de cada estado da Região Sudeste; duas universidades que possuem disciplinas que contenham exclusivamente horas de PCC e outras duas que contenham, em uma mesmo disciplina, horas dos eixos de PCC e Acadêmico Científico. Com isso, as universidades analisadas são: UERJ, UFSCar, UFES e UFTM. / The purpose of this paper was to research, from de graduation reform on university occurred in 2001, the constitution of the disciplinary axis called Practice as a curricular component (PCC) in the graduation curriculum of the language education - Portuguese / Spanish - courses in the southeast region of Brazil focusing on the relation between theory and practice. We based our discussion on the thoughts of Deleuze (1968) to question the possibilities of total repetition or total differentiation; Vázquez (1977), bringing his discussion about práxis that talks about the impossibility to dissociate theory and practice and Schwartz (2010, to incorporate the discussion of the field of labor, in particular what concerns the impossibility of complete anticipation of the activity to be accomplished by a professional. We operate, also, with the concepts of the Discourse Analysis (MAINGUENEAU, 1998, 2003) as we consider the enunciates as socio-historic situated during our analysis. To accomplish our goal, we did a documental contextualization that included the analysis of the legal document 28/2001, in which are the determinations about the amount of hours and the definition of the graduation discipline axis, being: Academic Scientific, Practice as an Curricular Component and Supervised Training. We looked, also, to the Politic Pedagogic Projects of the analyzed universities, in order to research the understanding of practice built in these documents. Finally, we turned to the syllabus of the obligatory disciplines of PCC offered by the chosen universities, trying to identify the marks that bring together the discipline theme and labor that considers the teacher's work, since the axis of PCC is about this discussion. As criteria to choose the university, we used: one university of each state from the southeast region; two universities with disciplines that have, exclusively, hours from the PCC and two others with disciplines of PCC and AC. Therefore, the universities are: UERJ, UFSCar, UFES e UFTM.

This study deals with analysis of the agricultural company layout. The utilization of agricultural areas is optimized with such a sowing technique that leads to the highest harvest profit. All these issues are being solved by the conversion to the linear programming model which is the most resembling to the combination of production planning and allocation problem. A case study is based on actual data given by Agrofarma Týnec, s.r.o. company. The 48 sections of field in different proportion are taken in consideration as well as five different crops. The study tries to deal with more options taking in account different trade prices of set commodities and a hectare sowing limitation. The main model anticipates pessimistic trade prices expectations and does not restrict hectare sowing with single crops. The model is followed by the price coefficient analysis that gives the price level to be kept to let the computed solution be optimal. Lingo13.0 was used as an optimization software.

Irving Singer's theory of value declares itself a member of american naturalistic and pragmatic tradition. It refuses metaphysical speculation on behalf of empirism and stresses the processual character of every experience, focusing more on its imaginatively-affective rather than rational part. Singer distinguishes two basic types of valuation: appriciation of an object, seen as an instrument for a given function, and spontaneous bestowal of value, which values the object on the basis of its own qualities - generating an affective attachement in the process. In a healthy organism, both ought to cooperate to support the fullness of life-in-the-world. Their harmonization is a matter of aesthetics as recognized in the case of love or works of art. This thesis criticizes Singer's project from its own point of view - the american naturalism. In the first chapter, it describes closely Singer's point-of-departure and places it within historical tradition. The matter of the "intrinsic value controversy" is drawn here as well. Following two chapters probe into the pillars of Singer's systém - the conceptions of appriciation, bestowal, imagination and idealization. In comparison with the doctrines of John Dewey, George Santayana and christian situational ethics, fundamentally eclectical character of Singer's...

For such, a epidemiological retrospective study was performed, analyzing the data of the demand of the Laboratory of IPEACS and Embrapa - PNPSA. The data bank was elaborated based on BT results, production indicators, management and other information referring to the farms and to the herds. The association among the presence of BT and the variables as: herd s aptitude, animal density, productivity, suckling system, suckling period, veterinary assistance, size of the herds, milk production, criterion for purchase, handling of manure, newborn management, mortality of calves. The region of the State were analyzed by the c2 test with correction of Yates, when necessary. In the bivariate analysis, the variables herd s aptitude, animal density, productivity, suckling system, suckling period, veterinary assistance had values of p ? 0,20, the multivariate analysis was submitted to generalized linear model. The historical tendency was evaluated by linear regression. The prevalence rate of BT on farms was 49,8% and it was presented in seven of the eight regions of the State, with significant differences (p = 0,03). The model that better explained the occurrence of BT in the herds included the variables: density, herd s aptitude, productivity, suckling system, suckling period as well as the interactions density x productivity, density x suckling system and productivity x suckling period. The increasing historical tendency of BT, with accentuated annual variations, could be due to the different motivations to the search of diagnostic. The economical organization of the production system was determinat in the occurrence of BT it could be evidenced by the variables that better explained its presence and its distribution in the analyzed population. / Os objetivos deste estudo foram determinar a preval?ncia, identificar os fatores associados, analisar a tend?ncia hist?rica e a distribui??o da tuberculose bovina (TB) em rebanhos, nos dados da demanda laboratorial do antigo Instituto de Pesquisa Agropecu?ria do Centro Sul (IPEACS) e da Empresa Brasileira de Pesquisa Agropecu?ria - Programa Nacional de Pesquisa em Sanidade Animal (Embrapa - PNPSA), do Estado do Rio de Janeiro. Para tal, um banco de dados foi elaborado com os resultados da tuberculiniza??o, indicadores de produ??o, de manejo e demais informa??es dos rebanhos de 209 propriedades rurais, referentes ao per?odo de 1959 a 1989. A associa??o entre a presen?a de TB e as vari?veis: aptid?o do rebanho, densidade animal, produtividade, sistema de aleitamento, per?odo, assist?ncia veterin?ria, tamanho do rebanho, produ??o de leite, crit?rio para compra, manejo de esterco, cuidados com rec?m-nascidos, mortalidade de bezerros e regi?o foi inicialmente analisada pelo teste de c2. Na an?lise bivariada, as vari?veis aptid?o do rebanho, densidade animal, produtividade, sistema de aleitamento, per?odo, assist?ncia veterin?ria apresentaram valores de p ? 0,20 e foram submetidas a an?lise multivariada por meio de modelo linear generalizado. A reta de tend?ncia hist?rica foi obtida por regress?o linear. A taxa de preval?ncia da TB nos rebanhos foi de 49,8% e esteve presente em sete das oito regi?es do Estado, com diferen?a significativa (p = 0,03). O modelo que melhor explicou a ocorr?ncia de TB nos rebanhos incluiu as vari?veis: densidade, aptid?o, produtividade, aleitamento e per?odo e as intera??es densidade x produtividade, densidade x aleitamento e produtividade x per?odo. A tend?ncia hist?rica crescente, com acentuadas varia??es anuais, pode ser, em parte, explicada pelas diferentes motiva??es para a busca do diagn?stico. A import?ncia da organiza??o econ?mica da produ??o pecu?ria na ocorr?ncia da TB, pode ser evidenciada pelas vari?veis que melhor explicaram sua presen?a e sua distribui??o na popula??o estudada.

Three methodologies were proposed for determination of infinite dilution activity coefficient of solutes in liquid mixtures (??). The ?? values were determined for 9 hydrocarbons in the solvent furfural at temperatures of 25, 35 and 45 ?C. The liquid-gas partition coefficients were also determined in each studied temperature. On the experiments involving liquid mixtures, high sorption of solvent was observed, which may lead to swelling the polymer coating phase. Statistical tests were conducted after each experiments to measure possible damages on fiber coatings. There was also proposed a methodology using the SPME to determine the Flory Huggins parameter of the nine hydrocarbons used as solutes in polydimethylsiloxane (PDMS) and polyacrylate (PA). The Flory parameter were determined at temperature range of 25 to 80 ?C for the PDMS and 50 to 90 ?C for the PA. The proposed methodologies were evaluated through comparison of the obtained data with literature. All the results agreed with literature data. The Hildebrandt solubility parameter for PA was not available on literature and was determined on these experiments for the first time / O principal objetivo deste trabalho foi o desenvolvimento de uma nova metodologia para determina??o de dados de equil?brio termodin?mico em misturas l?quidas e polim?ricas. Tr?s metodologias foram propostas utilizando a Microextra??o em Fase S?lida (SPME) para determina??o dos coeficientes de atividade em dilui??o infinita (??) de sistemas l?quidos. Os valores de ?? de 9 hidrocarbonetos foram determinados em furfural nas temperaturas de 25, 35 e 45 ?C. Foram determinados valores de coeficiente de parti??o l?quid-g?s (KLg) em cada uma das temperaturas estudadas. Nos experimentos envolvendo as misturas l?quidas, foi observada uma alta taxa de sor??o de solvente podendo ocasionar o inchamento e poss?vel quebramento das fibras de SPME. Para verificar o poss?vel inchamento, foram conduzidos testes estat?sticos antes e depois de cada amostragem. Foi proposto ainda uma metodologia para determinar os par?metros de Flory em polidimetilsiloxano (PDMS) e poliacrilato (PA) utilizando a SPME. Nesse caso, os mesmos 9 hidrocarbonetos tiveram seus par?metros de Flory determinados na faixa de temperatura 25 a 80 ?C para o PDMS e de 50 a 90 ?C para o PA. As metodologias foram avaliadas atrav?s da compara??o dos dados obtidos com dados da literatura. Todos os resultados foram satisfat?rios, sendo ainda obtidos os valores dos par?metros de solubilidade de Hildebrandt, que para o poliacrilato, eram inexistentes na literatura
