A crise do subprime e seus efeitos sobre os Estados Unidos e reflexos no Brasil

Between December 2007 and June 2009 the United States witnessed 18 months of recession that became known as the subprime crisis. Beginning in the housing market, the crisis moved into the banking and financial markets and spread throughout the entire economy through a domino effect, affecting the majority of other businesses. A major reflection of this was the large rise in unemployment rates due to business slashing jobs in an attempt to preserve cash. Although the crisis has officially ended, the unemployment rate reached over 10% in 2010 in the United States. American's continue to seek new jobs in a very difficult employment market, while attempting to manage the family household budget. American household income, which decreased either by pay cuts, job loss, and the effects of inflation, leads the majority of Americans to declare that the crisis had not yet ended. The crisis has spread to the world in varying degrees. Brazil was one of the countries least affected due to government policies and the large amount of foreign exchange. Although the crisis has affected Brazil only slightly, we will show how it reached this country and how the government solved this problem. This research paper will explain how the subprime crisis began, how it manifested itself in the U.S. economy and throughout the population. Also, it will show the crisis’ effects in Brazil and show some statements from Americans with their respective views and their experiences relative to the crisis

Comparação dos efeitos de compressão isostática e compressão uniaxial na obtenção da liga NiTi por metalurgia do pó

Several alloys present the shape memory effect and among them, the equiatomic NiTi alloy, nitinol, is the most important one. It is usually used in several engineering applications and also in biomedical devices, in the fabrication of orthodontic wire, stents and Judet staples. Although a considerable amount of these biomedical devices is utilized in Brazil and a fraction of it is already made here, all nitinol used is bought abroad. Thus, it is important to develop the necessary know-how to fabricate NiTi wire and sheet. It would mean less importation with job creation and wealth generation for the country. In this work nitinol was obtained powder metallurgy from elemental powders of Ti and Ni using uniaxial compression and uniaxial compression followed by isostatic compression. The final densities achieved were determined by the Archimedes method. The precipitation of intermetallic secondary phases was studied and the samples were characterized by metallographic analysis, optical microscopy and X-ray diffraction. Results indicated that 50 hours sintering route showed a low amount of intermetallics, and no trace of unreacted powder. XRD and metallography at room temperature indicated B19’ as the predominant phase, which corresponds to martensite. Although density results showed little dispersion, the most dense sample was compacted under uniaxial compression and presented 4.8 g/cm3, corresponding to 20.84% porosity. Density variation was considered normal to the measurement process and independent of the compaction mode

Ciência de serviços no Brasil: proposta de aplicação aos agronegócios

Ao se verificar nas últimas décadas a composição dos setores econômicos nos chamados países desenvolvidos e em desenvolvimento, nota-se um grande avanço e predominância do setor de serviços na composição de seu Produto Interno Bruto, chegando a ser na maioria dos casos o mais importante setor gerador de divisas, emprego e desenvolvimento. A Ciência de Serviços (CS) traz hoje a necessidade estratégica de políticas públicas, de ensino profissional e de pesquisas para o fomento e desenvolvimento desta Ciência no Brasil como fator estratégico para garantir uma maior competitividade da economia brasileira. A partir da hipótese de utilização da CS e de uma revisão bibliográfica do tema, buscou-se evidenciar suas potenciais aplicações no agronegócio, de maneira que este se torne mais eficiente, coordenado e sincronizado com o avanço dos serviços na composição da economia contemporânea nacional.

Medições de áreas por fotografias aéreas, em escala nominal, comparadas com a área obtida em fotografias com escalas corrigidas por meio de um SIG

Land use management has becoming a very important activity. Aerial photo interpretation is a basic resource and constitutes in a technique which enables infinite refining. Agricultural development and land use require a careful initial planning in order not only to protect them against superficial changing provoked by natural phenomenon but also to gradually develop its productive capacity. For the efficiency of land management, it is necessary to access correct and detailed information which can be available through aerial images of remote sensing. The use of vertical aerial photography through Remote Sensing has become more common in boundary survey projects, management and exploration, mainly because it substitutes, with lots of advantage, for cartographic bases, besides offering detailed characteristics, eliminating access difficulties in inaccessible areas, as well as facilitating a tridimensional view once it increases map efficiency and accuracy by combining field and laboratory work with photography interpretation. This work, using panchromatic aerial photography in nominal scale 1:25000 (1962), 1:45000 (1977) , and approximate nominal scale of 1:30.000, originating from aerial survey obtained in 2005, aimed at showing through the Geographic Information System (GIS) the possibility of developing a more complete and accurate analysis of the area values, obtained directly from photos without scale correction, and after comparing it with area values obtained from aerial photography with correct scale referred in IGC (Brazilian Cartography and Geography Institute) guidelines, resulting in an error coefficient which shows area differences through two proposed study. Considering the aerial photography in three different years: 1962, 1977 and 2005 it is possible to affirm that the 2005’s images presented lower values of area difference (43, 48 square meters) than determined area values in reference chart and the 2005’s colored images has facilitated the photo interpretation of the landscape, becoming accurate the confronting traces and among land owners and consequently offering precision during land marking.
