1. Políticas, procesos y trayectorias de privatización educativa en Latinoamérica
Abstract Pro-privatization policies are an increasingly important component in educational reform processes in many parts of the world. Latin America is the region in which educational privatization has advanced more sharply in recent decades. However, the academic literature on the subject is still scarce and there are few works that adopt a regional perspe

2. Sediment Morphology, Distribution, and Recent Transport Dynamics in a Reforested Fragment
Abstract Erosion generates large amounts of sediment, which may be deposited at the site of origin, on the slope of a hill, or along waterways. The transportability of each type of sediment by runoff and its potential for subsequent deposition largely depends on its morphological features and particle size distribution. The aim of this study is to describe a

3. Avaliação da composição isotópica do chumbo e da distribuição elementar nos sedimentos da represa Pedro Beicht, Cotia, São Paulo / Evaluation of isotopic composition of lead and elemental distribution in the sediments of the Pedro Beicht reservoir, Cotia, São Paulo
The water reservoir named Pedro Beicht provides water to five hundred thousand people in the metropolitan region of São Paulo city and is known by its excellent aquatic system quality. It is managed by Sanitation Company of São Paulo State (SABESP) and is surrounded by the Forest Reserve Morro Grande (RFMG). The RFMG was created in 1979 to ensure flora and

4. Rb-Sr systematics of holocene pelitic sediments and their bearing on whole-rock dating
In many cases, when dealing with argillaceous fine-grained sedimentary rocks, the isotopic ages obtained from Rb–Sr whole-rock isochron calculations are of geological significance, despite the fact that the initial conditions of Sr isotopic homogenization are not fulfilled. To explain this, a mechanical mixing during deposition has been suggested, leading

5. Impactos Socioambientais no EstuÃrio do Rio Jaguaribe: o Caso da Cidade de Aracati-Ce. / Social and Environmental Impacts on River Estuary Jaguaribe: If the City Aracati-Ce.
The Jaguaribe River was fundamental to the development of the city of Aracati. However, during recent decades a degradation of the fluvial and marine ecosystems caused by several environmental impacts has been perceived. Analyzing the social and environmental impacts at the estuary of the Jaguaribe River, highlighting the process of urban expansion from 1980

6. Evolução tectono-estratigráfica e paleoclimática da formação maricá (Escudo Sul-Rio-Grandense, Brasil) : um exercício de geologia histórica e análise integrada de uma bacia sedimentar neoproterozóica
Significant improvement in the knowledge concerning the Neoproterozoic Maricá Formation of the Sul-riograndense Shield, southern Brazil, was obtained in the latest years. This contribution synthesizes recent data obtained though an integrated analysis of the lowermost unit of the “Camaquã Basin”. Stratigraphic and paleocurrent analyses, petrography, Sr

7. Tempo de residÃncia da Ãgua em um sistema experimental de aquicultura integrada com camarÃes, ostras e macroalgas. / Residence time of water in an experimental integrated aquaculture with shrimp, oysters and seaweeds.
Shrimp culture presented at a world-wide level a significant growth in recent years, mainly in tropical and subtropical regions, however, this expansion comes with diverse environment negative impacts, mainly related to the cultures effluents, which are rich in nitrogen and phosphorous, that are many times discarded in the environment without any previous tr

8. Hydrological regionalization of flows and loads of total suspend solids for the program Producers of Water and the payment of environmental services. Case study of river basin Benevente, ES / Regionalização hidrológica de vazões e de cargas difusas de sólidos suspensos totais para o programa ProdutorES de Água e o pagamento de serviços ambientais. Estudo de caso: bacia hidrográfica do rio Benevente, ES
Systems of payment for environmental services of a catchment area can be economically attractive and ecologically important. Programs such as Producers of Water economically compensate owners upstream of the basin using the proper management of land use, and reforestation to prevent erosion, increased pollution loads diffuse and increase the availability and

9. Sediment distribution model in marine shelf area : a cambrian example from the Sergipano Belt (Lagarto Formation, Estancia Domain, Sergipe) / Modelo de distribuição de sedimento em area de plataforma marinha : um exemplo do cambriano da faixa sergipana (Formação Lagarto, Dominio Estancia, Sergipe)
Coastal areas of wave-influenced tidal plains are not well known in recent and ancient depositional systems. The Lagarto Formation represents one of these mixed depositional systems influenced both by tide and wave activities. This work describes the sediments in this system, interprets the depositional processes and defines a distributional model of sedimen

10. Determination of the recent depositional history of Santos and São Vicente Estuary, based on heavy-metal contents and magnetic susceptibility of the sediments / Determinação da história deposicional recente do Alto Estuário Santista, com base nos teores de metais e na suscetiblidade magnética dos sedimentos
O Sistema Estuarino de Santos e São Vicente, localizado na porção central do litoral do Estado de São Paulo, abriga o mais importante complexo industrial costeiro do País, o Complexo Industrial de Cubatão, e o maior porto brasileiro, o Porto de Santos. Os objetivos deste trabalho foram o estudo do histórico da contaminação da área por metais pesado

11. Case report of lymph nodal, hepatic and splenic tuberculosis in an HIV-positive patient
We describe a case of a male patient, 38 years old, HIV-positive (most recent CD4 count about 259/mm³), with abdominal pain, nausea, vomiting, anorexia, weight loss, and vespertine high fever with chills. His hemogram showed normocytic and normochromic anemia, with a high erythrocyte sedimentation rate (ESR) and gross granulations in the neutrophils. Transa

12. Evolução morfodinâmica da região de influência estuarina do Rio Curimataú/RN, com ênfase nas alternativas do ambiente deposicional de manguezal e a integração de geodados em Sig
The estuaries are important investigation zones of the actual morphodynamic and of depositional facies of recent geological history. They are constituted in important receptor means of the coastal area sediments, where the evolutionary processes occur quickly. They are also attractive means for the development of anthropic activities, which in a disordered w
