Border crossings in Mercosur countries: obstacles and their cost

In a recent ECLAC study of inefficiency at border crossings in Mercosur countries, it was found that the cost of delays in traffic between Argentina and Brazil amounted to a minimum of US$ 170 per truck for the most problematic border crossing. This is over 10 % higher than the typical price of freight between Buenos Aires and Sao Paulo or Porto Alegre. It was estimated that the extra-cost on this border crossing may amount to a maximum of US$ 273 per truck. These problems, which have to do more with organization than with infrastructure, cause serious losses to the sectors involved in international transport, and especially to end users of intermediate or consumer goods transported.This edition of the Bulletin includes a summary of a study entitled: Identificación de obstáculos al transporte terrestre internacional de cargas en el Mercosur: los casos de Argentina, Brasil y Uruguay.

Reinforcing production cooperation and dialogue spaces: the role of SMEs

Políticas de integração na fronteira trinacional Brasil, Peru e Bolívia

As áreas de fronteiras internacionais constituem espaços altamente complexos, marcados pela grande diversidade de agentes étnicos e de identidade plurinacionais. Na Amazônia Sul Ocidental, tem-se uma área geopolítica estratégica de fronteira trinacional composta pelo Acre (Brasil), Madre de Dios (Peru) e Pando (Bolívia). A preocupação com a segurança nacional, da qual emana a criação de um território especial ao longo do limite internacional continental do país, embora legítima, não tem sido acompanhada de uma política pública sistemática que atenda às especificidades regionais, nem do ponto de vista econômico, nem da cidadania fronteiriça. A integração física do Brasil, como questão central do interesse nacional e do combate às atividades ilícitas, atribui às fronteiras novo papel estratégico. Reativam-se, assim, o interesse pelas fronteiras a partir desse duplo processo, tornando as relações transfronteiriças um tema prioritário das relações internacionais. Com efeito, a busca de um novo significado para as interações do Brasil com seus países limítrofes vem impondo o redirecionamento da ação do Estado brasileiro, com reflexos na geopolítica internacional dessa região da América do Sul. O objetivo central deste estudo é analisar as políticas e ações de integração regional, no processo de desenvolvimento, em uma área de fronteira sob a jurisdição trinacional do Brasil, Peru e Bolívia.

Echocardiographic and radiographic aspects of tetralogy of Fallot in a Border Collie: case report

Tetralogy of Fallot is a complex cardiac malformation characterized by four anatomical defects: pulmonary valve stenosis, right ventricular hypertrophy, interventricular septal defect and aortic dextroposition. Imaging techniques are useful in the diagnosis of this disease, such as radiography for screening and Doppler echocardiography for a definitive diagnosis. Our objective is to report the radiographic and Doppler echocardiographic aspects of a tetralogy of Fallot case in a 10 month-old Border Collie dog.

Agricultura familiar em Rio Claro - SP: em busca de alternativas para permanência no campo

As we focusing in the Brazilian rural area we see that it presents the spatial diversity and the different organization forms of the space arising from its diversity, tied to the different economic, social, politic and cultural contexts .These contextual diversities bring results that is not limited to the agrarian sector, but get beyond the border of the rural world, taking different ways of organization and structuring in the urban areas. The building and management of the rural spaces are constituted as an attribute of the agricultural production that in the course of the centuries made disappear and reduce significant proportions from the natural areas. In many places, the intensification of the production process gives satisfaction to the globalized markets and that return allows the reproduction of the productive conditions. In other areas the access difficulties to the market and the proximity to the developed urban centers cause the abandonment of the agricultural activity and the maintenance of property without production or with specific services (tourism, for example). That process triggers a multiplicity of factors that are defining the pace of the rural areas in Brazil. This work sought to understand all the deals of the ‘’rural’’ county of Rio Claro-SP and what’s the role and the situation that we find the familiar agriculture in the advanced urban areas, which is the case of this study. Where the agriculture doesn’t represent the flagship of the economy. It was the intention, identify what activities and practices socio-spatial are developed in the county rural area. Trying to understand the public politics acts in the promotion and encouragement to the already developed activities or even other activities that can represent the possibility of a social and territorial reproduction of the families on the country

Discrete quantum phase spaces and the mod N invariance

An extended Weyl-Wigner transformation which maps operators onto periodic discrete quantum phase space representatives is discussed in which a mod N invariance is explicitly implemented. The relevance of this invariance for the mapped expression of products of operators is discussed. © 1992.

Immunolocalization of aquaporins 1 and 9 in the ram efferent ducts and epididymis

Aquaporins (AQPs) are essential membrane protein channels for the transport of water across membranes. Fluid movement in the epididymis is important for modulation of the luminal environment, in which sperm mature and reside. This study was designed to understand the morphology and localization of AQPs in ram efferent ducts (ED) and epididymis. For this purpose, the epididymis of seven animals were removed for histologic and immunohistochemical analyses. AQP1 immunoreactivity was observed in the apex of the ED, and AQP9 was found adjacent to the nuclei of the epithelial cells of the ED. The epithelial lining of ram epididymis is pseudostratified columnar and presents principal, basal, apical and narrow cells. In the initial segment (IS), a moderate reaction for AQP1 was observed in the apical cytoplasm of epithelial cells. An intense reactivity for AQP1 was noted over the microvilli of principal cells and in spermatozoa in the caput. In the corpus and cauda, AQP1 was noted only over the endothelial cells of vascular channels located in intertubular spaces. A weak-to-moderate reaction for AQP9 was observed in the nuclei of epithelial cells in the IS, caput and corpus of the epididymis. In the cauda, an intense reaction to AQP9 was observed in the epithelial border. In the IS, caput and corpus, the reactivity for AQP9 differed from those observed in domestic animals. The cauda showed a pattern similar to that previously described. These results indicate that AQPs 1 and 9 have reversed locations and roles in rams, suggesting activity variations related with fluid and solute absorption throughout the epididymis.

On universal Banach spaces of density continuum

We consider the question whether there exists a Banach space X of density continuum such that every Banach space of density at most continuum isomorphically embeds into X (called a universal Banach space of density c). It is well known that a""(a)/c (0) is such a space if we assume the continuum hypothesis. Some additional set-theoretic assumption is indeed needed, as we prove in the main result of this paper that it is consistent with the usual axioms of set-theory that there is no universal Banach space of density c. Thus, the problem of the existence of a universal Banach space of density c is undecidable using the usual axioms of set-theory. We also prove that it is consistent that there are universal Banach spaces of density c, but a""(a)/c (0) is not among them. This relies on the proof of the consistency of the nonexistence of an isomorphic embedding of C([0, c]) into a""(a)/c (0).

MAXIMAL PSEUDOCOMPACT AND MAXIMAL R-CLOSED SPACES

In this paper a space X is pseudocompact if it is Tychonoff and every real-valued continuous function on X is bounded. We obtain conditions under which a Tychonoff space is maximal pseudocompact and study conditions under which a regular space is maximal R-closed.
