This master thesis is dedicated to Russian development and determinants of its growth. Just two decades ago Russia experienced a total change in the political and economic structure of the country. USSR fall, together will all its successes and failures. Russia went to the path of building a market economy, while the rest of the developed world was already living in such economy and using its benefits. With the heritage of the USSR, Russia had a huge potential to be successful in that road. The goal of this work is to answer the question, whether or not we were able to use it. In order to answer this question two-stage analysis was performed, combining theoretical and quantitative parts. Theoretical part contains the overall analysis of the areas of economic and social development. Quantitative part contains analysis of the main GDP drivers and endogenous powers of industrial production. Powered by TCPDF (www.tcpdf.org)

Experimental procedures are presented, as well as the results of the thermal and acoustic performance of this composite material, made from an expansive foam derived from the castor seed oil and fiber of scrap tires. The residue was treated superficially with sodium hydroxide, to eliminate contaminants, and characterized macroscopically and microscopically. Samples were produced with addition of residues at levels of 5%, 10%, 15% and 20% by weight, for determination of thermal properties: conductivity, heat capacity and thermal diffusivity, sound absortion index and density. The results were compared to commercially available thermal insulation and sound absorbing products. According to the analysis of results, it was concluded that the developed composite presents characteristics that qualify it as a thermal insulation with superior performance, compared to commercial available insulation, and sound absorption capacity greater than the castor oil polyurethane s, without addition of the residue / Neste trabalho tratou-se do desenvolvimento de um material inovador constitu?do de matriz poliuret?nica vegetal e carga de res?duo industrial, proveniente de recauchutagem de pneus, para fins de isola??o t?rmica e conforto ambiental. Para tanto, s?o apresentados procedimentos e resultados experimentais obtidos da an?lise do desempenho t?rmico e ac?stico desse material comp?sito produzido a partir de resina expansiva derivada do ?leo da semente de mamona e fibras de pneus inserv?veis. O res?duo foi tratado superficialmente com hidr?xido de s?dio, para a elimina??o de impurezas, e caracterizados macrosc?pica e microscopicamente. Foram produzidos corpos de prova com adi??o de res?duo nas propor??es de 5%, 10%, 15% e 20% em massa, para determina??o de propriedades t?rmicas: condutividade, capacidade calor?fica e difusividade t?rmica, do ?ndice de absor??o sonora e densidade aparente. Os resultados foram comparados aos isolantes t?rmicos e absorventes sonoros comerciais. De acordo com a an?lise dos resultados, concluiu-se que o comp?sito desenvolvido possui caracter?sticas que o qualificam como um isolante t?rmico com desempenho superior aos isolantes comerciais e com capacidade de absor??o sonora maior que o poliuretano de mamona sem a adi??o do res?duo

From the initial demand to project and build a new laboratory in a specific refinery, in order to attend the current work and the future work load increase, a key question was raised, the necessity to understand the laboratory work reality face the prescribed work. This case study has analyzed the labor in many subunits, or, Production Centers of the studied laboratory according to the Ergonomics Analysis of Work approach. It dares the necessity to understand the work organization, positioning the activity as central to the analysis, and unfold issues such the human relations at work. After doing the observations, transcriptions, analyses and auto-confrontation it was realized that, although the procedures prescription has been prescribed by the workers themselves, it was relatively simple and did not take into account the variety of activities. Therefore the workers resort of many means that were learned, created or incorporated to execute the tasks. These information, variability and situations are managed by the worker´s competencies, and are highlighted through specific skills, from previous and acquired knowledge, and from past experience. Due the competency to deal with work in this environment, it may be said that the workers adopt individual and collective strategies to manage the work, overcome the variability and the existing risks in order to produce reliable certifications ensuring health and productivity. / Esse trabalho foi realizado em um laboratório de análise química situado dentro de uma refinaria brasileira. A partir da demanda inicial de se projetar e construir um novo laboratório em uma refinaria específica, que viesse atender o trabalho atual e o aumento futuro da carga de trabalho, foi levantada uma questão chave, a necessidade de compreender a realidade no trabalho em laboratório de analise química em contraposição ao trabalho prescrito. Esse Estudo de Caso analisou o trabalho em várias subunidades, ou seja, Centros de Produção, existentes no laboratório estudado segundo a abordagem da Análise Ergonômica do Trabalho. Ela incita a necessidade de compreender a organização de trabalho, coloca a atividade de trabalho no centro da análise, e revela questões como a relação dos homens no trabalho. Após as observações, transcrições, análises e autoconfrontações constatou-se que apesar de os procedimentos serem prescritos pelos próprios trabalhadores, esses documentos são relativamente simples e não levam em conta a variedade de atividades. Dessa forma, os trabalhadores recorrem a vários meios aprendidos, criados ou incorporados para executar as tarefas. Essas informações, variabilidades e situações são administradas em virtude da competência dos trabalhadores, e são evidenciadas por meio de habilidades específicas, de conhecimentos prévios e adquiridos, e de experiências em diversas situações. Devido à competência em lidar com o trabalho nesse ambiente de produção, pode-se dizer que os trabalhadores adotam estratégias individuais e coletivas para gerir o trabalho, superar as variabilidades e os riscos existentes no intuito de produzir certificações confiáveis preservando a saúde e a produtividade.
