Brasil - Argentina e o Sistema Regional de Salvaguardas Nucleares

In 2011, the Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials (ABACC), created to administer the Common System of Accounting and Control of Nuclear Material (CSAC) has completed twenty years of existence. ABACC and the Quadripartite Agreement established with International Atomic Energy Agency (IAEA) are a special system of safeguards that presents itself as an important example of regional contribution to global nuclear proliferation. The paper presents some considerations about the process of understanding between Brazil and Argentina that resulted in the creation of ABACC, indicates succinctly some theoretical explanations of international relations for this process and, from some features of the Agency, relates how the ABACC experience could support nuclear weapons free zones.

Composi����o e abund��ncia da ictiofauna de duas lagunas costeiras da Am��rica do Sul Austral: lagoa do Peixe (31��S; 51��W), Brasil e laguna Mar Chiquita (37��S; 57��W), Argentina

This article describes and compares the shallow water fish-fauna from two coastal lagoons (Peixe Lagoon, in Brazil, and Mar Chiquita Lagoon, in Argentina). Peixe Lagoon was sampled between 2000 and 2001 using a 9 m beach seine net (12 mm bar mesh in the wings and 5 mm in the centre 3 m section) totalizing 125 samples, which yielded 33,848 individuals and 32 species. Mar Chiquita Lagoon was sampled from 1995 to 1998 using a 21) m beach seine net (12 mm bar mesh) totalizing 232 samples resulting in 31,097 individuals of 28 species. A total of 47 species were observed in both lagoons and 13 were shared. The "marine-estuarine-related" species were similar and dominate the fish assemblages in both lagoons. The remaining species were similar to the species collected along the southern Brazil, Uruguay and Argentina estuaries. The number of species observed in Peixe Lagoon (S = 32) was higher than in Mar Chiquita Lagoon (S = 28) and is probably associated with a strong latitudinal gradient of species richness increasing from north to south. Considering that the Peixe Lagoon and Mar Chiquita Lagoon are isolated by the large estuaries of Patos Lagoon and Prata River, the composition of the species with low abundance and occasional occurrence were different for each local studied. These results expand the knowledge for the fauna of both sites and help conservation and management from both lagoons.

Imagens do Brasil nas relações de viagem dos s��culos XVII e XVIII

O presente ensaio toma como objeto de an��lise uma s��rie de descri����es do Rio de Janeiro colonial extra��das de narrativas de viagem escritas por europeus que passaram pela cidade entre os s��culos XVII e XVIII. Para al��m de dar a conhecer a perspectiva que esses visitantes deixaram da urbe e de seus habitantes, seu objetivo �� p��r em discuss��o o papel que os relatos de viagem desempenharam no processo de constru����o da imagem que o europeu da ��poca tinha do brasileiro e, sobretudo, o papel que posteriormente desempenharam no processo de constru����o da imagem que o brasileiro, a partir do s��culo XIX, passou a ter de si pr��prio e do seu pa��s.

Alfabetiza����o no Brasil: conjecturas sobre as relações entre pol��ticas p��blicas e seus sujeitos privados

As complexas e pol��micas quest��es relativas a formula����o, implementa����o e avalia����o de pol��ticas p��blicas para a educa����o no Brasil, nas ��ltimas d��cadas, v��m sendo objeto de importantes estudos e pesquisas. Como resultado, tem-se acumulado significativo corpo de conhecimentos a esse respeito, o que propicia avan��os no debate e possibilita novos estudos e pesquisas a respeito de aspectos cada vez mais espec��ficos da tem��tica. Com o objetivo de contribuir para esse debate, apresentam-se neste artigo conjecturas a respeito da rela����o entre setores p��blicos estatais decorrente especificamente do novo tipo de parceria entre ��rg��os p��blicos do Estado e docentes pesquisadores das universidades p��blicas para formula����o, implementa����o e avalia����o de pol��ticas p��blicas para a alfabetiza����o, iniciada na d��cada de 1980 e enfatizada a partir da d��cada de 1990, com a reforma do Estado brasileiro.

Relações entre condutividade hidr��ulica, transmissividade, condut��ncia longitudinal e s��lidos totais dissolvidos para o aqu��fero livre de Ca��apava do Sul (RS), Brasil

A ��gua subterr��nea �� um importante recurso ao abastecimento p��blico, principalmente para comunidades perif��ricas em grandes cidades ou pequenos munic��pios, onde a instala����o ou prolongamento de sistemas de distribui����o s��o economicamente invi��veis. Estudos voltados �� an��lise da vulnerabilidade de aqu��feros s��o relevantes para subs��dio a pol��ticas p��blicas em saneamento b��sico e preserva����o ambiental. Este estudo contou com o cadastro de 23 po��os rasos localizados no munic��pio de Ca��apava do Sul (RS), onde foram realizadas medidas de resistividade el��trica e cargabilidade por meio de geof��sica, e medidas diretas de condutividade hidr��ulica e s��lidos totais dissolvidos. A an��lise estat��stica dos dados demonstrou diversos graus de correla����o entre par��metros, basicamente condicionados a fatores geol��gicos como porosidade, permeabilidade e s��lidos totais dissolvidos.

Federalismo e relações intergovernamentais no Brasil: a reforma de programas sociais

The article analyses the process of reform in four areas of social policies that affect directly the interests of sub-national governments: basic education, social housing programs, basic sanitation and health. As the study reveals, despite the varying degree of success achieved in the various policy initiatives and contrary to the expectations of the prevailing interpretations of the nature of Brazilian federalism, the federal government faced no insurmountable hurdles in implementing their reform agenda. The study aims at demonstrating that (i) in the absence of any constitutional mandatory requirement, the political autonomy of local governments - typical of federative States - actually enhances the veto power of local governments over policy initiatives proposed by the federal Executive branch. However, (ii) power resources available to the federal Executive branch - such as agenda definition and vetoing powers - in addition to control over resources that are essential to the political survival of the representatives increase the chances of success-of the federal government. Furthermore, (1999), (iii) the constitutional authority of Brazilian states is far more limited than that of the North-American states; (iv) the category federalism, however, is not sufficient to define the potential stability of specific policies, which depends upon how inter-governmental relations are structured in each particular policy. Specifically, (v) constitutional rules, legacies from previous policies and the political cycle frame the decision arenas in various ways, thus conditioning both the strategies and chances of success of the federative players.

Influ��ncia do arcabou��o hidroestratigr��fico nas ocorr��ncias de ars��nio em ��guas subterr��neas ao longo do corredor termal do rio Uruguai (Argentina - Brasil - Uruguai)

The Thermal Corridor of Uruguay River is located in the triple border of Argentine, Brazil and Uruguay, and shows an intense economic thermal tourism activity, mainly based on groundwaters from Guarani Aquifer System (GAS). Recent studies have pointed out the occurrence of high concentrations of arsenic (>10 ��g/L) in GAS groundwater in this area. The complex geological and hydrogeological framework in the area is associated to the Paran�� Basin geological evolution south of the Assuncion-Rio Grande Arch; it encompass paleozoic marine sequences and continental sequences permian/eotriassic to mesozoic in age, which are covered by basaltic lavas of Serra Geral Formation. Iron oxide coatings have been described in sandstones of Buena Vista and Sanga do Cabral formations, which underlie GAS units. Arsenic occurrence is associated to sodium bicarbonate groundwater with pH values over 8.0. Arsenic is released to groundwater by desorption from iron oxides/hydroxides, as result of the higher pH of these waters, indicating that arsenic is released from the units that underlie GAS units. Increase in chromium and uranium concentrations are also related to high pH groundwaters, thus indicating special care on using groundwater from this region.
