A INSERÇÃO ECONÔMICA INTERNACIONAL E A VULNERABILIDADE EXTERNA DO BRASIL E DA ARGENTINA (1990-1999) / THE INSERT INTERNATIONAL ECONOMIC AND THE FOREIGN VULNERABILITY OF BRAZIL AND ARGENTINA (1990-1999)

Fagundes, Jeferson Mandracio 29 August 2008 (has links)
This study examines the international economic integration of Brazil and Argentina during the period of 1990-1999, and assesses the vulnerability of the two foreign countries. From the evolution of the flows of trade balance (coefficient of openness), the balance of services and capital, is the analysis of international economic integration. The analysis of the current account deficit, of how it is financed, the denationalization of the economy, the balance of international reserves of foreign debt and the coefficient of vulnerability, will assess the behavior of external vulnerability. It follows that the international economic integration of Brazil and Argentina, through the adoption of policies of adjustment recommended by the Washington Consensus, took place in a subordinate and dependent on large economic and financial centers, to the extent that the two countries acted as receivers in the pattern of shortterm, resulting from trade liberalization, supported by the overvalued exchange rate, which caused a structural change in the trade balance, making it the deficit. There was an increase in vulnerability in the two countries, because the external accounts have deteriorated, increased the foreign debt grew and the degree of internationalization of production through greater presence of foreign equity companies, increasing the concentration of wealth and power in the hands of international groups. Moreover, the inadequacy and inconsistency of these policies are also evidenced by the low GDP growth and rising unemployment. / Este estudo analisa a inserção econômica internacional do Brasil e da Argentina, no período de 1990-1999, e avalia a vulnerabilidade externa dos dois países. A partir da evolução dos fluxos da balança comercial (coeficiente de abertura), da balança de serviços e de capitais, é feita a análise da inserção econômica internacional. Com a análise do déficit em conta corrente, da forma com que ele é financiado, da desnacionalização da economia, do saldo das reservas internacionais, do endividamento externo e do coeficiente de vulnerabilidade, será avaliado o comportamento da vulnerabilidade externa. Conclui-se que a inserção econômica internacional de Brasil e Argentina, através da adoção das políticas de ajuste recomendadas pelo Consenso de Washington, deu-se de forma subordinada e dependente aos grandes centros econômicos e financeiros, na medida em que os dois países atuaram como receptores dos fluxos financeiros de curto prazo, resultantes da abertura comercial, apoiadas na sobrevalorização do câmbio, a qual provocou uma mudança estrutural na balança comercial, tornando-a deficitária. Verifica-se que houve um aumento na vulnerabilidade nos dois países, pois as contas externas se deterioraram, aumentou o endividamento externo e cresceu o grau de internacionalização da produção por meio de maior presença de empresas de capital estrangeiro, ampliando a concentração de renda e poder nas mãos de grupos internacionais. Além disso, a inconsistência e a inadequação dessas políticas também são comprovadas pelo baixo crescimento do PIB e pelo aumento do desemprego.

Optimalizace rozvozu a svozu infuzních roztoků / Optimization distribution and collection of infusion solutions

Kravciv, Zbyněk January 2009 (has links)
There are many distribution tasks, that vary in a number of vehicles, time windows, dividend or undivided delivery or if it is static problems or dynamic problems. In this essay I focus just on few of them. At first I put my mind to simple statistic distribution task with one vehicle. Later I extend it with time windows, when the point can be served by one car and by many cars. In the essay it will be solved the real task of distribution and delivery transportation of infusion in the hospitals. Because of the difficulty of solution I have to use the heuristic methods - Method of nearest neighbour, Savings method and Insert method. All these methods are modified by capacity requirements, time windows and also observence of the rules, which the drivers have to keep during a distribution. The aim is to minimize the distance travelled by the vehicles. And at least the company could be recommended the best solution.

Leia (e entenda) a bula: estudo da compreensibilidade em bulas de medicamentos brasileira e alemã / Read (and understand) the package insert: study of the comprehensibility in Brazilian and German package inserts

Cintra, Adriana Dominici 23 September 2015 (has links)
Nesta dissertação, foi desenvolvida uma análise linguística contrastiva de bulas de medicamento brasileiras e alemãs. O principal objetivo dessa análise era identificar o grau de compreensibilidade de cada um dos textos, segundo as dimensões do modelo de Karlsruhe: Concisão, Correção, Motivação, Estrutura, Simplicidade e Perceptibilidade. Para isso, foram retomados conceitos da Linguística Textual e procedimentos da Textologia Contrastiva, como as definições de texto e gênero textual, o método de comparação de textos paralelos e o estabelecimento de um termo de comparação. De maneira geral, os resultados da análise contrastiva indicaram que termos técnicos (no âmbito da simplicidade) e fonte pequena (no âmbito da perceptibilidade) não são as principais causas de incompreensão na leitura das bulas, como se supôs inicialmente. O estudo evidenciou que desvios na estrutura e na concisão das bulas podem ter um impacto tão ou mais negativo na compreensão desses textos do que os aspectos anteriormente citados. Além disso, foi possível constatar que cada uma das dimensões possui um peso diferente na compreensibilidade das bulas analisadas devido a diferenças linguísticas e culturais entre os pares alemão/português e Alemanha/Brasil. / In this research, a contrastive linguistic analysis of German and Brazilian package inserts was developed. The main aim of this analysis was to identify the degree of comprehensibility in each text, according to the Karlsruhe model dimensions: concision, correctness, motivation, structure, simplicity and perceptibility. To achieve this aim, it was necessary to review some concepts of the Textual Linguistics and procedures of the Contrastive Textology, such as the definitions of text and textual genre, the method of comparing parallel texts and the establishment of a point of comparison. In general, the results of the contrastive analysis have shown that technical terms (in the scope of simplicity) and small font (perceptibility) are not the main causes of misunderstanding of package inserts, as it was supposed initially. The study has highlighted that deviances in the structure and in the concision of package inserts may have an impact in the comprehension of these texts as negative as the aspects forementioned, if not more. Moreover, it was possible to notice that each dimension has a different weight in the comprehensibility of the analyzed package inserts because of the linguistic and cultural differences between German/Portuguese and Germany/Brazil.

Volba optimálního nástroje pro vybranou technologii obrábění / Selection of an optimal tool for the selected machining technology

Podstata, Jan January 2020 (has links)
This thesis compares the properties of four types of replaceable cutting tool inserts from different suppliers during milling. The comparative factors are cutting force, material loss of the insert and the roughness of the resulting surface. The thesis is divided into two parts - a comprehensive overview of the current state of knowledge and an experiment. The first part analyzes the load, the possibility of its measurement, surface treatment of tools, milling cutters and replaceable inserts. The experiment took the form of measuring the load during face milling, measuring the surface roughness of the machined material and measuring the material loss of the inserts on an optical strain gauge. The replaceable cutting tool inserts were compared based on the performed measurements.
