Estruturas de acumulação de água subterrânea em rochas cristalinas: estudo geofísico e geológico de casos no Estado do Rio Grande do Norte

Geological and geophysical studies (resistivity, self potential and VLF) were undertaken in the Tararaca and Santa Rita farms, respectively close to the Santo Antônio and Santa Cruz villages, eastern Rio Grande do Norte State, NE Brazil. Their aim was to characterize water acummulation structures in crystalline rocks. Based on geological and geophysical data, two models were characterized, the fracture-stream and the eluvio-alluvial through, in part already described in the literature. In the Tararaca Farm, a water well was located in a NW-trending streamlet; surrounding outcrops display fractures with the same orientation. Apparent resistivity sections, accross the stream channel, confirm fracturing at depth. The VLF profiles systematically display an alignment of equivalent current density anomalies, coinciding with the stream. Based on such data, the classical fracture-stream model seems to be well characterized at this place. In the Santa Rita Farm, a NE-trending stream display a metric-thick eluvioregolith-alluvial cover. The outcropping bedrock do not present fractures paralell to the stream direction, although the latter coincides with the trend of the gneiss foliation, which dips to the south. Geophysical data confirm the absence of a fracture zone at this place, but delineate the borders of a through-shaped structure filled with sediments (alluvium and regolith). The southern border of this structure dips steeper compared to the northern one. This water acummulation structure corresponds to an alternative model as regards to the classical fracture-stream, being named as the eluvio-alluvial trough. Its local controls are the drainage and relief, coupled with the bedrock weathering preferentially following foliation planes, generating the asymmetry of the through

A produção capitalista do espaço: os loteamentos, os condomínios fechados e o seu papel na formação do Bairro de Nova Parnamirim/Parnamirim-RN

This work exposed desired to investigate the function of evolution of closed allotment, of market of the earth and of forms of extraction of the lace of earth, in the processes capitalist production of urban space in Nova Parnamirim, community of Parnamirim/RN. This tendentious urbanization were marked for an expressive increase of number of horizontal and vertical closed residences joint ownership concerning at social groups more privileged financial position. Go after, set off, a temporal investigation, based in the forms of appropriation of space in the middle intermediate by action of the several producers agent of capitalist capital. This way, make necessary understand the past of local structure earth, in order that to make possible analyze the beginning of the process. Not enough, appealed the publics institutions as immobile notary s office and secretary municipal for to collect the more important information, and in the field through of application of formulary together the population of ward, in order that of examine the motivation of residential establishment inside. Make this, confirmed that the actual spatial organization of ward of Nova Parnamirim started of two allotments: the Vale do Pitimbú Park and Eucaliptos Park, both divided in several little allotments. Before of begin the ward, allotments reproduced set off from that native has been consigned during the 80, 90 decade s and begin the actual century, resigning a complicated urban structure earth, dynamized by exploration of a promising residential area. Leashed of this, confirmed the installation of logic of segregation and auto-segregation conducted by an immobile market which exclude the poor class and absorb rich class, motivate by perspective of obtaining of urban lace of earth by immobile promoter. However, perceived that the growth this market was promoted by migration of groups of capital, interior of state and others regions of country. Not distant, horizontal and vertical closed residences represent production forms of a new form of residence, corresponding the pattern architectonic as socioeconomics, strengthened by ideal of security, quality of life, necessity of reclusion and of proximity of Natal. Is in the capital which this individual found possibilities of attend satisfactory minimum of yours necessity in relation a consumption of bens and specialized and specifics services. Before this qualitative perceive that the social and spacial differential of Nova Parnamirim was the responsible by soil and habitation valorization of ward, that reinforce the promotion of segregation and of auto-segregation, and consequently, of capitalist reproduction of urban space

As transformações fundiárias da comunidade de sibaúma-rn com o advento do turismo

The genesis of the research emerges from reflection about the space dynamics of the capital and to the capital. The expansion and the incorporation of territory for capital reveal, in part, strategies of the capitalism production way, which shows the search for accumulation conditions, expanding the alternatives of territory use that is, nowadays, selective and uneven. The present work verified the mechanisms where the capital imposes its practices through the agrarian structure and the valuation of land market, meaning, in our knowledge, that the reproduction of inequalities is showed, many times, by the wide land speculation and the fast land valuation. For this, the snip space will be the Sibaúma community, belonging to Tibau do Sul district, located in Rio Grande do Norte state. It‟s a rural area that has, gradually, changing through the advent of urban characteristics, given the association of public and private investments, both domestic and international. Through the empirical observations, inside the Sibaúma community, it was found expansion strategies, incorporation and appropriation of territory by capital. As a result of this practice, it‟s occurring the land valuation and the presence of a process of socio-spatial segregation, through the encouraging the opening of new subdivisions, mainly for construction of second homes and tourism enterprises in order to meet the demand of a higher socioeconomic level. The areas still available in Sibaúma, constitute into a reserve of value for the achievement of capitalist rent, being a mechanism of capital reproduction. In this way, to studying the socio-spatial transformations, caused by spatial valuation, we turn to the project of social space designed by Santos(2006), from the perspective of capitalist production of space, by understanding the historical process of formation, the mechanisms and the actions of social actors that produce and consume space

Acumulação de matéria seca e macronutrientes pelo sorgo sacarino

Foram colhidas amostras de plantas de dois cultivares de sorgo sacarino (Brandes e Rio), cultivados em um Latossol Roxo, de 20 em 20 dias, onde se analisou a acumulação de matéria seca, N, P, K, Ca, Mg e S. Ambos os cultivares apresentaram maior velocidade de absorção para a maioria dos nutrientes no período compreendido entre o aparecimento do primórdío da panícula e o florescimento, com algumas excessões. O cultivar Brandes apresentou maiores velocidades de absorção de nutrientes do que o cultivar Rio, nos períodos de máxima taxa de absorção, mesmo apresentando ciclo longo.

Acumulação de micronutrientes pelo sorgo sacarino

Amostras de plantas de dois cultivares de sorgo sacarino (Brandes e Rio) cultivados em um Latossol Roxo, foram colhidas de 20 em 20 dias, e foram realizadas analises de B, Cu, Fe, Mn e Zn nas diversas partes da planta. Os estádios fisiológicos em que ocorreram as maiores velocidades de absorção não foram coincidentes para os dois cultivares para a maioria dos micronutrientes. Osorgo sacarino demonstrou uma alta absorção de Fe na fase de crescimento vegetativo para a cv. Rio (35 g/ha dia) e na fase do emborrachamento até florescimento para o cultivar Brandes (47 ,5 g/ha dia).

Fragmentos de um modelo: pequenas lavouras de café e acumulação de capitais. Franca/São Paulo 1890-1914

Este artigo versa sobre a importância da pequena cafeicultura no complexo cafeeiro entre 1890 e 1914. Discutimos aqui as relações de trabalho, as formas de financiamento e o modo como a pequena propriedade se insere neste universo. Utilizamos como fontes prioritárias os contratos de trabalho que envolviam a formação e/ou o trato de cafeeiros e as escrituras de dívidas hipotecárias, ambas lavradas nos Livros Cartoriais, fontes estas ainda não trabalhadas pela historiografia de forma mais sistemática. Desviamos nosso olhar para uma região marcada predominantemente pelas pequenas e médias fazendas produtoras de café, observando a dinâmica da acumulação em um período de expansão e de crise da cafeicultura.

Limites e contradições da cidadania na sociedade capitalista

O artigo defende o argumento de que a lógica objetiva das relações sociais capitalistas opõe-se ao desenvolvimento da moral e da cidadania. Também argumenta que a cidadania é uma representação idealizada que não tem força para superar a alienação das relações sociais, que têm o dinheiro como mediação universal em nossa sociedade. Por fim, o artigo analisa criticamente a proposta curricular do Estado de São Paulo para o ensino de filosofia no Ensino Médio, a qual tem como referência a pedagogia das competências.

A questão do desenvolvimento à luz da globalização da economia capitalista

Cet article cherche à dresser, sous la perspective historique, le bilan de la situation des pays périphériques dans les dernières trentes années. Pour cela, il aborde particulièrement les enjeux du développement dans la phase de la globalisation du capital. Ce travail s'appuie surtout sur les études de la vaste bibliographie publiée récemment. Dans quelle mesure la relance du développement concernant plusieurs secteurs stagnés de la périphérie deviendrait-elle une réelle possibilité? Autour de cette question, que nous trouvons centrale dans l'actuelle conjoncture, nous entamons quelques réflexions. Nous envisageons montrer que la stagnation économique à laquelle des nombreux pays non développés font face ne découle pas en partie d'une crise sociale et économique ouverte dans les années soixante-dix et qui s'élargit jusqu'à nos jours malgré les tentatives de restructuration de la société capitaliste. Les stratégies et les mesures politiques à caractère néo-liberal aussi auraient énormément contribué à cette situation étant donné qu'elles ont renforcé les amarres financières qui ont étranglé pour une part les économies périphériques. Outre ces difficultés, ces pays affronteraient les limites écologiques du capitalisme. La relance du développement dans un nouveau stade exigeant la croissance économique, la justice sociale et la préservation de la nature amènerait à une rupture face au capitalisme.
