Multilatinas na global economy. historical characterization, sectorial and space

The successive crises for which has passed in the world economy since the years 1970, together with the United States 'hegemonic crisis, have created the conditions for the reordering and the construction of a multipolar world, with the increasing importance of some peripheral countries into the world economy, particularly with regard to capital flows. This article represents an effort to bring to light the analysis on the decrease of importance of developed countries in world investment flows and corresponding increase in the relevance of some peripheral countries. The objective underlying the text is understanding the expansion of space circuits of production of multinational companies in Latin America (Multilatinas) at different spatial scales, by means of an analysis of the temporal, spatial and sectoral dimensions of the investments. The methodological procedures adopted covered survey, selection and bibliographic data compilation, reading in international organizations (UNCTAD and ECLAC), systematization of data, analysis of data in the light of the theoretical reflections.

A insegurança e as novas práticas espaciais em cidades brasileiras

New real estate launch products and closed residential spaces, occurs with increasing frequency in Brazilian cities and are based on the assumption that there is a general increase in violence, as we address urban insecurity, which involves individual coping, and privatizing adept practices of exacerbated control mechanisms. We researched deployment and appropriation of residential spaces in middle cities of Sao Paulo (Brazil). We identify social representations of the others, blamed for insecurity growing, and analyzed from everyday life perspective. We hypothesized that new forms of production of urban space with a tendency to social and spatial fragmentation, generate new practices.

Permian stromatolites associated with bivalve coquina beds-Angatuba, SP, Brazil (Teresina Formation, Parana Basin)

Silicified stromatolites have been described in the Permian Teresina Formation, Passa Dois Group, of the Parana Basin. These stromatolites occur as blocks in the Fazenda Monte Alegre area at the headwaters of the creek known as Corrego Catanduva in the municipality of Angatuba. These blocks originate from the Serra de Angatuba region and were recognized in a road that was cut in the midst of sandstones and siltites. The stromatolites are isolated bioherms that are domed to subspherical with a flat base in profile and a rounded to lenticular shape in plan view. The stromatolites exhibit a reddish coloration and are composed of microcrystalline quartz. Lamination is continuous, non-columnar, and anastomosed, showing parallel to divergent growth; however, divergent columns also occur, especially at the tops of the bioherms. The lamination is fine and well preserved, with alternating light and dark laminas. Microfossils of filamentous cyanobacteria are preserved and were related to the genera Microcoleus and Rivularia. Silicified bivalves occur in association with the stromatolites and are preserved in the form of coquina beds and rare isolated specimens within the bioherms. The described specimens belong to the Pinzonella illusa biozone, with representatives of the species Pinzonella illusa, Angatubia cowperesioides, and Houldausiella elongata. The formation environment of these stromatolites is associated with tidal plains of shallow, brackish, relatively calm, warm waters of good luminosity with the presence of weak currents. There was likely a low level of predation, and the environment may have been hypersaline. The coquina beds associated with the stromatolites indicate a probable proximal tempestite, i.e., they were formed near the coastline. The stromatolites were originally composed of carbonates, although these were replaced by silica during early diagenesis.

A palaeobiologist's guide to 'virtual' micro-CT preparation

This paper provides a brief but comprehensive guide to creating, preparing and dissecting a 'virtual' fossil, using a worked example to demonstrate some standard data processing techniques. Computed tomography (CT) is a 3D imaging modality for producing 'virtual' models of an object on a computer. In the last decade, CT technology has greatly improved, allowing bigger and denser objects to be scanned increasingly rapidly. The technique has now reached a stage where systems can facilitate large-scale, non-destructive comparative studies of extinct fossils and their living relatives. Consequently the main limiting factor in CT-based analyses is no longer scanning, but the hurdles of data processing (see disclaimer). The latter comprises the techniques required to convert a 3D CT volume (stack of digital slices) into a virtual image of the fossil that can be prepared (separated) from the matrix and 'dissected' into its anatomical parts. This technique can be applied to specimens or part of specimens embedded in the rock matrix that until now have been otherwise impossible to visualise. This paper presents a suggested workflow explaining the steps required, using as example a fossil tooth of Sphenacanthus hybodoides (Egerton), a shark from the Late Carboniferous of England. The original NHMUK copyrighted CT slice stack can be downloaded for practice of the described techniques, which include segmentation, rendering, movie animation, stereo-anaglyphy, data storage and dissemination. Fragile, rare specimens and type materials in university and museum collections can therefore be virtually processed for a variety of purposes, including virtual loans, website illustrations, publications and digital collections. Micro-CT and other 3D imaging techniques are increasingly utilized to facilitate data sharing among scientists and on education and outreach projects. Hence there is the potential to usher in a new era of global scientific collaboration and public communication using specimens in museum collections.

Essa pesquisa tem como objetivo a análise do conflito pela terra no Pontal do Paranapanema (Estado de São Paulo, Brasil), considerando a disputa pelos recursos hídricos e a degradação da saúde ambiental na área denominada do agrohidronegócio canavieiro. Os resultados da pesquisa indicam que a expansão do cultivo da cana nessa região está provocando o agravamento da saúde dos trabalhadores. Por outro lado, a pesquisa também procura identificar modelos alternativos ao projeto hegemônico de desenvolvimento regional baseado na matriz agrohidroenergética. Para isto, a pesquisa tem como interlocutores diversos tipos de movimentos sociais, como o Movimento dos Trabalhadores Sem Terra e o Movimento dos Atingidos por Barragem, além de lideranças sindicais.

THE CONQUEST OF CENTRAL BRAZIL: FRONTIERS AND FRONTS PIONEERING IN THE NINETEENTH CENTURY

The process of territorial formation in Brazil is examined in this paper in order to establish, through a study that favors more interior region of Portuguese America, a suitable analytical arsenal geohistorica an interpretation of the built legacy of colonial Lusitanian action on American soil. Thus, it is expected to recover some aspects not yet addressed conclusively by the specialized literature, the importance of colonial territorial nexus in the construction and maintenance of the substrate material on which the new politically independent state would claim jurisdiction after 1822. Through the examination of so-called western border, articulated through the contacts held between the cities network of Goias and the strong, prisons, villages and towns planned in Mato Grosso, outline an interpretation of regional dynamics in the moments preceding the running of the Brazilian political emancipation.

The IDEOLOGY SPACE BRAZILIAN NATIONAL STATE OF CONSTITUTIVE

In the debate over the construction of the Brazilian national state, we assume that this process has established itself at the heart of a fragmentary appreciation of their aesthetic variants, forming a controversial ideology spatial sense of identity to the nation. progress, modernization and territorial integration emerge as slogans on the link between the imagined nation, Brazil Imperial, and the nation as concretized throughout the twentieth century, despite the discourse and actions in the rescue culture synthesis Brazilianness. It is evident, that scope, a tendency to think the nation more as a product of a cultural elite (fragments of baroque and colonial cities consecrated) than through symbols forming territories hybrids representatives of all of their constructors: the antagonistic protagonists.

TITANS OF CAPITALISM IN THE MODERNIZATION OF BRAZILIAN TERRITORY: URBAN AND AWARDS PUBLIC ASSISTANCE DURING THE FIRST REPUBLIC (1889-1930)

In Brazil, the newly created Republic expressed interests of the elite increasingly committed to foreign capital. The Rio de Janeiro saw accumulate vast resources in trade and finance, deriving for industrial applications. The city appears as articulator of Brazilian territory and mediation between it and the international market. In the capital of the Republic, the conservative plan would sweep the old city and inaugurate images copied from Europe and installed in the tropics with civilizing purpose. This materialized with infrastructure financing and loans to entrepreneurs in Europe and North America, awarded public service concessions. The project relied on strong support of mayors (members or representatives of the companies involved in the reforms). This work aims to address the relationship between the mayors of Rio de Janeiro during the First Republic and international capital, focusing on strategies for the production of new spaces in motion the modernization of Brazil and its international image.

BIOCIVILIZACAO: OVERVIEW AND BACKGROUND TO COMPLETE OUR independence

Latin American countries have a privileged position to tackle the environmental crisis, producing a new framework of relations and interdependencies: a biocivilizacao. Inspired by the ideas and Gourou Sachs, founded in centralities other than those of the "global market", and fed by other "sources" than those of high-carbon, embodied in examples like those provided by the Amazons, that teach us how the interaction between cultural and natural elements can produce the main source of biodiversity on the planet and your invaluable environmental service. Countries that share, if you can settle in other conditions (have) dependencies, guided references and values different from those that have chaired the hegemonic order. But for that, the paths that lead only to "cooperate" with the construction of "common markets", which will be replaced by others, eg, dialogues between the Organization of the Amazon Cooperation Treaty and Pan Amazonian Social Forum.

Evaluación de las Prestaciones de una Red WiMAX Móvil en un Escenario de Alta Movilidad

The aim of this paper is to evaluate the performance of mobile WiMAX technology for users in a highly mobility scenario for an operating frequency of 3.5 GHz. By utilizing a modified version of the extended Erceg’s propagation model, based on the introduction of Rayleigh fading due to multipath, we have calculated the received desired power and the interference power to obtain the statistical signal-to-interference-plusnoise rate (as a function of mean value and variance of cochannel interference) and the user throughput. A rural scenario composed of a transmitting base station and users in moving vehicles along a cell sector is proposed. The obtained results about coverage and throughput have been simulated by a tool built in MATLAB

Array Compacto De Monopolos Planos Con Plano De Tierra Ranurado Para Sistemas Mimo

A compact array of monopoles with a slotted ground plane is analyzed for being used in MIMO systems. Compact arrays suffer usually from high coupling which degrades significantly MIMO benefits. Through a matching network, main drawbacks can be solved, although it tends to provide a low bandwidth. The studied design is an array of monopoles with a slot in the ground plane. The slot shape is optimized with a Genetic Algorithm and an own electromagnetic software based on MoM in order to fulfill main figures of merit within a significant bandwidth
