Droughts surfaced in 1877 as a crucial problem for the birthing Brazilian nation. Engineers, who formed the country's technical and scientific elite, took it upon themselves to study, understand and fight the problem through planned actions of intervention on space. This work, based on proposals and discussions contained in engineering magazines and reports, aims to provide elements for the comprehension of how these systematized actions against droughts, in the Iate nineteenth and early twentieth century, contributed to spatial analysis and the formation of a (then-inexistent) regional and territorial planning discipline in Brazi!. Engineers, by taking up the position of masterminds in the country's modernization, guaranteed for themselves personal economic stability, social prestige and political power. By understanding nature, either as a resource to be exploited or an adversary to national progress, they contributed to the delimitation of the region now known as the Northeast. By seeking to understand the drought phenomenon, they created knowledge about the space they sought to intervene on; by constructing their projects amid political and economical difficulty, they changed the organizational structures of cities and country in the northeast. The proposals for açudes (Iarge water reservoirs) allowed the fixation of population and the resistance against droughts; the roads - railroads and automotive roadways - connected the sertão to the capitais and the coast, speeding up help to the affected populations during droughts and allowing the circulation of goods so as to strengthen the local economies in normal rimes. The adopted practices and techniques, adapted from foreign experience and developed through trial and improvement, were consolidated as an eminently spatial intervention course, even if a theoretical body of regional or territorial planning wasn't formed in Brazil. Regional Planning proper was first applied in the country in the Northeast itself, in the 1950s, based off an economical view of reality in order to achieve development. The engineer's work prior tothat date, however, cannot be dlsconsldered. It was proved that, despite facing financial and political hurdles, engineers had a profound commitment to the problem and intended to act systematically to transform the economical and social relations in the region, in order to be victorious in their struggle against droughts

This Masters Degree dissertation seeks to make a comparative study of internal air temperature data, simulated through the thermal computer application DesignBuilder 1.2, and data registered in loco through HOBO® Temp Data Logger, in a Social Housing Prototype (HIS), located at the Central Campus of the Federal University of Rio Grande do Norte UFRN. The prototype was designed and built seeking strategies of thermal comfort recommended for the local climate where the study was carried out, and built with panels of cellular concrete by Construtora DoisA, a collaborator of research project REPESC Rede de Pesquisa em Eficiência Energética de Sistemas Construtivos (Research Network on Energy Efficiency of Construction Systems), an integral part of Habitare program. The methodology employed carefully examined the problem, reviewed the bibliography, analyzing the major aspects related to computer simulations for thermal performance of buildings, such as climate characterization of the region under study and users thermal comfort demands. The DesignBuilder 1.2 computer application was used as a simulation tool, and theoretical alterations were carried out in the prototype, then they were compared with the parameters of thermal comfort adopted, based on the area s current technical literature. Analyses of the comparative studies were performed through graphical outputs for a better understanding of air temperature amplitudes and thermal comfort conditions. The data used for the characterization of external air temperature were obtained from the Test Reference Year (TRY), defined for the study area (Natal-RN). Thus the author also performed comparative studies for TRY data registered in the years 2006, 2007 and 2008, at weather station Davis Precision Station, located at the Instituto Nacional de Pesquisas Espaciais INPE-CRN (National Institute of Space Research), in a neighboring area of UFRN s Central Campus. The conclusions observed from the comparative studies performed among computer simulations, and the local records obtained from the studied prototype, point out that the simulations performed in naturally ventilated buildings is quite a complex task, due to the applications limitations, mainly owed to the complexity of air flow phenomena, the influence of comfort conditions in the surrounding areas and climate records. Lastly, regarding the use of the application DesignBuilder 1.2 in the present study, one may conclude that it is a good tool for computer simulations. However, it needs some adjustments to improve reliability in its use. There is a need for continued research, considering the dedication of users to the prototype, as well as the thermal charges of the equipment, in order to check sensitivity

Na última década houve uma retomada de investimentos na construção naval brasileira o que resultou em uma expansão e modernização da capacidade produtiva dos estaleiros nacionais. Os estaleiros nacionais ainda precisam atingir um nível de excelência operacional compatível com o observado nos países líderes de mercado O trabalho apresenta tópicos adotados por estaleiros estrangeiros bem sucedidos e que podem ser implantadas pelos estaleiros brasileiros com o intuito de torná-los competitivos mundialmente. Para isso, realizou-se um estudo de caso em um estaleiro nacional, cujo foco foi o levantamento das tecnologias e processos em uso nesse estaleiro e a classificação com relação às melhores práticas mundiais (benchmarks). Um método de benchmarking desenvolvido para construção de navios foi utilizado no presente estudo. O trabalho pode servir como fonte de informações para realizar ajustes para melhorias em processos produtivos, redução de tempos de ciclo e melhor utilização da mão-de-obra. Dessa forma, pode contribuir para posicionar a situação atual do estaleiro e verificar as necessidades para torná-lo competitivo internacionalmente.

Este estilo de desarrollo del país no ha generado encadenamientos productivos y recurre constantemente, a políticas implementadas en la promoción de las exportaciones, liberalización y apertura comercial, drásticos ajustes en las funciones del Estado y la atracción de inversión extranjera (tanto directa como financiera). Objetivos que se materializan en la negociación de tratados de libre comercio al estilo del Tratado de Libre Comercio entre Centroamérica y Estados Unidos. En él se sientan las bases institucionales para la flexibilización del accionar del capital global, la profundización del proceso de apropiación de los factores de producción (básicamente, los recursos y servicios naturales, y la fuerza de trabajo) e incorporar nuevos negocios en sectores que, precisamente, suponen las mejores posibilidades de incrementar la acumulación de capital, siendo éstos, hoy, los recursos energéticos y hídricos. Abstract This style of development of the country has not generated productive linkages and it constantly appeals, to politicians implemented in the promotion of the exports, liberalization and opening commercial, drastic adjustments in the functions of the State and the attraction of foreign investment (so much direct as financial). Objectives that are materialized in the negotiation of treaties of free trade to the style of the Treaty of Free Trade between Central America and United States. In him they feel the institutional bases for the flexibility of working of the global capital, the to make deeper of the process of appropriation of the production factors (basically, the resources and natural services, and the work force) and to incorporate new business in sectors that, in fact, they suppose the best possibilities to increase the capital accumulation, being these, today, the energy and hydric resources.

Two cheese formulations made from raw milk and endogenous yeasts with 30, 60 and 180 days of maturation in two dairy Paraná Southwest were studied to evaluate their quality through physical, physical-chemical, microbiological and sensorial characteristics, as one of the stages of development of a typical regional cheese. The production was accompanied from designing the flowchart processing, where the samples were collected to perform the analysis of proteins, lipids, moisture, ash, carbohydrates, total solids, fat in dry matter, calories; water activity, instrumental texture (hardness, adhesiveness, springiness, cohesiveness, resiliency and chewiness), instrumental color (CIE Lab); microbiological quality was assessed searching for total and thermotolerant coliforms, coagulase positive staphylococci and Salmonella spp.; the acceptance related to sensory characteristics of color, appearance, flavor, texture, taste and purchase intent was evaluated through the structured hedonic scale. This research contributed information relevant to the production process, such as the realization of the viability in freeze-drying lactic acid bacteria yeast isolated from milk in the Southwestern Mesoregion of Parana and the results of the analysis of the cheese showed similarity between formulations, regarding the physical, physical-chemical characterization, moreover good microbiological quality, where the differences between samples of dairy products were not perceived by sensory panelists. Adjustments in standardization related to technological quality control is an extremely important factor for the success of dairy companies and small producers involved in the project and that they have the option of producing the Santo Giorno, a fine cheese, with the great advantage of adding features of region, with high standard of sanitary conditions and with great consumer acceptance of indicative.
