O artigo discute, sob uma perspectiva institucionalista, a dimensão do problema fundiário brasileiro expresso pela fragilidade dos direitos de propriedade da terra rural. Além dos condicionantes históricos referidos no texto, o artigo chama a atenção para o papel das instituições de registro e cadastro de imóveis que, por estarem separadas e não integradas, favorecem as práticas de fraude, apossamento e potencializam os conflitos fundiários. O artigo conclui com uma proposta de mudança institucional, baseada no aumento da governança da terra, no recente contexto favorável ao aperfeiçoamento da estrutura de direitos de propriedade da terra.

Em Santa Bárbara D'Oeste,SP, foram realizados dois mapeamentos do uso da terra em área de 14.625 ha. No primeiro utilizou-se fotografias aéreas verticais pancromáticas (data de 25/6/78), na escala 1:35.000, e no segundo utilizou-se imagens orbitais do satélite LANDSAT-5 com sensor Thematic Mapper (data de 12/8/91), escala 1: 100.000, nas bandas 3, 4 e 5 e composição colorida 3/4/5. Para auxiliar a confecção desses mapas, obteve-se chaves de interpretação, tanto para as aerofotos como para as imagens orbitais. As fotografias aéreas proporcionaram um maior nível de detalhamento na identificação do uso da terra. A banda 3 e a composição colorida 3/4/5 foram as mais eficientes entre as imagens orbitais. Entre 1978 e 1991, a área de ocorrência de cana-de-açúcar permaneceu a mesma, as áreas de mata e pastagem diminuíram, enquanto que as áreas de reflorestamento e urbana aumentaram. Essa região teve sua capacidade de uso enquadrada, na maior parte, na classe IV: terras mais apropriadas para pastagens ou plantas perenes como a cana-de-açúcar, devendo-se aplicar técnicas intensivas de conservação, e com aptidão baseada em práticas agrícolas que refletem um alto nível tecnológico.

"Looking at earth from blind: travel in the visuality of the test on Blindness" is a literary Essay resulted from the experience of different points of view regarding the Essay on Blindness (1996), not only showing a Modern aesthetical tendency in dialog with the Baroque one, but also discussing subjects related to the History of Mentalities. The chapters are disposed as follows: The first one presents a short Excursus about the author and his work; the second one introduces the concept of Allegory exemplifying it with representative images of Romance; the third one presents tragic elements in dialog with the Bataille Eroticism in an Allegory of Feeling; the fourth one shows Stylistic Features used as a display mean of Comedy in Romance going towards the musicalness, being the features used to provoke laugh; the fifth and last one discusses about the study pertinence. To conclude, in favor of a Sight Education, the study considered authors such as: Ariès (1977), Bataille (2003), Bakhtin (2002, 2000, 1999), Benjamin (2000, 1996), Chauí (2005, 2000), Foucault (2006, 2005, 2004, 2002), Freud (1970), Hansen (2006), Lino (2004), Sartre (2005), Vovelle (1996)

In this dissertation we argue that the work Terra Natal, by the poet Ferreira Itajubá, presents, predominantly, themes and forms typical of the Romantic period, although it came out in 1914, when the romantic aesthetic was no longer popular in Brazilian Literature. Firstly, we discuss about Ferreira Itajubá s biography, his bibliographic production as well as the critical fortune of his works. Secondly, we outline the course of the Romantic Movement from its emergence in Europe to its arrival in Brazil as well as its impact in the state of Rio Grande do Norte. Finally, we analyze of Terra Natal, taking into account other aspects such as context and structure through the analysis of the poems VII, IX, XVIII, XXI and also of the song Viola , inserted in the poem VIII. We highlight the following romantic themes during the analysis: exile, nostalgia for the past, cult of native land, the romantic view of woman, projection of soul s state on nature, and religiosity. We will try to create dialogues between Terra Natal and works of popular Romantic Brazilian writers, such as Gonçalves Dias, Casimiro de Abreu, José de Alencar,Visconde de Taunay and Castro Alves, in order to show the affiliation of the above-referenced work and the Romantic ideals

Praziquantel has been shown to be highly effective against all known species of Schistosoma infecting humans. Spherical nanoparticles made of poly(D,L-lactide-co-glycolide) acid with controlled size were designed as drug carriers. Praziquantel, a hydrophobic drug, was entrapped into the polymeric nanoparticles with 30% (w/w) of theoretical loading. The nanoparticles size was approximately of 350 nm with 66% of encapsulation efficiency. The everted gut sac model shows to be efficient to evaluate the drug permeation through the intestinal membrane. The results show that free praziquantel presents 4-fold times more permeation than praziquantel-loaded PLGA nanoparticles and physical mixture. For this drug, in special, this result can be interesting, since the nanoparticulate system can behave as a drug reservoir and/or to have a more localized effect in intestinal membrane for a prolonged period of time, since great amounts of parasites can be usually found in the mesenteric veins.

Ce travail est un étude de cas qui analyse la construction litéraire du paysage du « Sertão» du Ceará entre la fin du siècle XIX et le début du siècle XX. Pour cela, quelques oeuvre simbole de la production litéraire du Ceará ont été sélectionnés, comme les textes qui suivent: O sertanejo (1875), de José Martiniano de Alencar; Os retirantes (1879), de José Carlos do Patrocínio; A fome (1890), de Rodolfo Marcos Teófilo; Luzia-Homem (1903), de Domingos Olímpio Braga Cavalcanti; Terra de sol: natureza e costumes do Norte (1912), de Gustavo Dodt Barroso et finalement, Aves de arribação (1914), de Antônio Sales. Ces oeuvres non seulement prend la nature comme personage, elles représentent aussi trois moments de la production litéraire du Ceará : romantique, réaliste et naturaliste. A invenção da Terra da Luz se rapporte à l idée d une littérature qui fait remarquer le paysage diurne du Sertão du Ceará, élaborée par ces hommes des lettres dans ses discours formidables, beaux et des matériaux qui viennent de ses rapports avec le monde naturel. Pour réaliser une tel entreprise, les idées de Edmund Burke et Gaston Bachelard se sont constitués en référence de cet étude. Et cette réflexion sur la description, la rêverie et l imagination marchent côte-à-côte au discours de ces littéreurs qui ont construits un espace simbolique spécifique : le sertão du Ceará. Comme ça, quelques thèmes deviennent canonique à la forme de penser, représenter et imaginer l espace du sertão du Ceará. De cette manière, le paysage est beaucoup plus que la contemplation, une fois qu elle est liée aussi à la rêverie poétique, à la mémoire et l imagination. C est de là l invention du paysage, car ces littéreurs n ont pas l accès au paysage purement naturel parce que ses perceptions et sensibilitées sur le monde du sertão ont été historiquement, c est-à-dire, dans un certain temps et espace

Foi instalado um experimento em condições de campo, em um Latossolo Vermelho escuro, epi-eutrófico, textura argilosa, em Selvíria-MS, com arroz de sequeiro cv. IAC 201, estudando-se três espaçamentos entre fileiras (30, 40 e 50 cm) e três densidades de semeadura (100, 150 e 200 sementes viáveis/m2). Foram avaliadas a produção de matéria seca da parte aérea no momento do florescimento e determinados os teores e quantidades de N, P, K, Ca, Mg e S absorvidos, assim como a eficiência de utilização de nutrientes. A redução do espaçamento entre fileiras aumentou a produção de matéria seca da parte aérea e a quantidade de nutrientes absorvidos. A variação da densidade de semeadura não afetou os parâmetros estudados. A redução do espaçamento entre fileiras proporcionou maior eficiência de utilização do Ca e diminuiu a do N e Mg. Os teores de nutrientes na matéria seca da parte aérea não foram afetados pela variação do espaçamento entre fileiras.

The following dissertation studies the insertion of peasant women in the conflict for land since the occupation process, dispossession and construction of the settlement New Horizon II, in the municipal district of Maxaranguape. It analyses their participation in the conflict Valley of the Hope", that resulted in the settlements New Life II and New Horizon II in the municipal district of Maxaranguape. The analysis exposes the reasons which took the peasant women, after the land conquest, to go back into domestic space and/or to assume positions of lesser relevance in the political organizations of the settlement. In the conflict Valley of the Hope, the women had a fundamental role, facing the police violence, being front line of the conflicts against the repression forces, risking their lives and the life of their families. After the conquest of the land, transformed into the New Horizon II Settlement, there are a lot of changes in the participation of the women. We can observe that, despite the protagonism of the families, in special of the women in the Valley of the Hope conflict, these female workers still experiment unequal social, economic, political and cultural conditions in relation to the men, expressing the gender inequalities which are found in the daily life of the settlement: in the community, in the domestic and agricultural task. The conflict for the land in the Valley of the Hope and the conquest of the settlement did not necessarily mean the incorporation of the emancipation of the peasant women. However, the political participation in the development of the conflicts allowed to the women the self discovering and the beginning of an emancipation process as gender. There are signals of continuities and ruptures of the present culture, almost always stimulated by the organization of the agricultural female workers

The monitoring of Earth dam makes use of visual inspection and instrumentation to identify and characterize the deterioration that compromises the security of earth dams and associated structures. The visual inspection is subjective and can lead to misinterpretation or omission of important information and, some problems are detected too late. The instrumentation are efficient but certain technical or operational issues can cause restrictions. Thereby, visual inspections and instrumentation can lead to a lack of information. Geophysics offers consolidated, low-cost methods that are non-invasive, non-destructive and low cost. They have a strong potential and can be used assisting instrumentation. In the case that a visual inspection and strumentation does not provide all the necessary information, geophysical methods would provide more complete and relevant information. In order to test these theories, geophysical acquisitions were performed using Georadar (GPR), Electric resistivity, Seismic refraction, and Refraction Microtremor (ReMi) on the dike of the dam in Sant Llorenç de Montgai, located in the province of Lleida, 145 km from Barcelona, Catalonia. The results confirmed that the geophysical methods used each responded satisfactorily to the conditions of the earth dike, the anomalies present and the geological features found, such as alluvium and carbonate and evaporite rocks. It has also been confirmed that these methods, when used in an integrated manner, are able to reduce the ambiguities in individual interpretations. They facilitate improved imaging of the interior dikes and of major geological features, thus inspecting the massif and its foundation. Consequently, the results obtained in this study demonstrated that these geophysical methods are sufficiently effective for inspecting earth dams and they are an important tool in the instrumentation and visual inspection of the security of the dams

The research Reforma Agrária de Mercado e Territorialização: um estudo a partir do Programa Cédula da Terra em Canindé-Ce , has an objective to discuss until whas time denominated agrarium refom has capacity of territory the of families in Five from the seven settlements cmated by resourles from the prgramme cell of earth em Canindé-Ce. In this context, the present work analysis the relation sitip between power and kind of identity, in special in those settlements, trying to learn the dialetic relationship. That passes by the process and appropriation in these spaces by these families gave the beginning of buying the land. The procedure methologic used by us gave privilege to realize the interview included in this process, wita the leaders of rural associations (STR); commission clero of earth (CPT); rural workers movement without land (MST); wita agricolas tecnics, and so the local coordinators of cell of earth in Fortaleza. The analysis of agrarium reform in Canindé, infects that the families giving entrance in buying the land, they could creatieg a hope in quality of life for getting the land. Nevertheless, it did not happen, in the rost of the parts of the areas in study. The territories present in general focus, the worse process of poomest besides the amount of debiths of these families, putting in risk the territorialization of themselves
