Estudo sobre os tipos de manifestações no campo paulista no período 2000-2011

Este trabalho visa contribuir com os estudos sobre a luta pela terra no contexto atual, qualificando os dados do Banco de Dados da Luta pela Terra (DATALUTA). Esta qualificação dos dados é um processo permanente dentro do Núcleo de Estudos, Pesquisas e Projetos de Reforma Agrária (NERA) e Rede DATALUTA. Nesta análise estudamos os tipos das manifestações do campo no processo de luta pela e na terra, com base nos registros da Comissão Pastoral da Terra (CPT), fazendo uma análise entre 2000 e 2011 no estado de São Paulo. Com isso, buscamos compreender a importância das manifestações dos movimentos socioterritoriais camponeses como um elemento da luta pela terra, no bojo da questão agrária brasileira. Para isso utilizamos dos conceitos geográficos de espacialização da luta, território material e imaterial e desenvolvimento territorial. Assim, relacionamos as manifestações como ações que espacializam a luta pela terra na conquista do território, reivindicando políticas públicas para o seu desenvolvimento colaborando para evidenciar o território imaterial camponês aliado ao paradigma da questão agrária

Avaliação de sistemas de pultrudados com diferentes tipos de matrizes para aplicação em cabos condutores

In the last decades it has been observed a substantial developing of the electrical energy demand in the societies all over the World. In consequence the electrical energy distribution companies are increasing the quantity of electrical energy through the electrical energy conductor cables, which had grown the sag in the towers of energy transmission. Furthermore, the construction of more transmission towers brings a lot of troubles due environmental protection laws. In this way, looking forward to increase the quantity of electrical energy transmitted through electrical cables conductors, reduce the need of constructing new transmission towers and the sag in them, we suggest in this work the replace of the traditional core of the conductors cables commonly used, made of steel, by a core made by a composite material, which one is made by carbon fibers pultruded with polymeric resins as matrix. In a order to evaluate if the resins more commonly used in structural composites can be applied as matrix to make possible to use the composite material as a core, we made carbon fibers systems pultruded with epoxy, phenolic and polyester resins as matrix and a mechanic and physic-chemistry characterization was done on the systems by Tensile and Poisson tests, differential sprobe calorimetry (DSC), thermogravimetric analysis (TGA) and Fourier transformed infrared spectroscopy (FTIR), following their correspondents standards

Comparação de eficiências do uso de sistemas construídos de áreas alagadas (Constructed Wetland Systems - CWS), tipos ascendente e descendente, para tratamento de efluentes

Water is an essential element for life. The use of this element, to support the community, defines it as water resource. This feature is being misused and degraded by the dumping of highly contaminated effluents. The impoverishment of its quality poses a risk to human consumption. The necessity to manage this resource, treating the wastewater properly, requires the constant improvement of treatment systems. Another need is to adjust the cost of systems to the demands of communities with less financial clout. This study aimed to adapt and understand the systems of wetlands, improving its efficiency, in an attempt to collaborate with the enrichment of this technology. The practical evidence, with lab-scale prototypes, assembled in ETE Piracicamirim with urban sewage effluent contributed to highlight the problems and operating system design. The bibliographic review showed that several studies had effectiveness for treatment. But it was evident the need for better understanding of dimensioning definitions that better attempted to the answers into the project. Moreover, standardization of system conditions for the specific wastewater treatment is an interesting field, identified, for future studies yet contribute to environmental engineering and sanitation

Análise da assimetria na corrida de aproximação de diferentes tipos de chute no futsal

Existe uma lacuna na literatura no que diz respeito chutes no futsal, ainda mais em relação as diferenças entre membros contralaterais. Portanto o objetivo do estudo foi analisar e comparar os parâmetros espaço-temporais da corrida de aproximação e de desempenho (precisão e velocidade da bola) de chutes realizados com o membro dominante e membro não dominante para diferentes tipos de chutes no futsal, separadamente para a bola em posição estacionária e para a bola em deslocamento. Participaram do estudo cinco jogadores destros e cinco jogadores sinistros de futsal da equipe adulta da UNESP – Campus Rio Claro. Os participantes realizaram 10 chutes com a bola parada e 10 chutes com a bola em deslocamento, sendo que em cada situação 5 chutes foram realizados com o membro dominante (MD) e os outros 5 chutes com o membro não dominante (MND). Para a bola parada os chutes foram realizados na marca do tiro livre (10 m distante do gol). Para bola em deslocamento foi utilizada uma rampa para padronizar a velocidade de chegada da bola. Os participantes foram instruídos a realizar o chute com o dorso do pé o mais forte que conseguir, tendo como objetivo acerta um alvo de 1m² posicionado no centro do gol. Os chutes foram filmados por seis câmeras digitais JVC® modelo GR9800u, ajustadas com freqüência de aquisição de 120 Hz, shutter a 1/250, white balance e o foco definido de forma manual. Foram fixados marcadores nas proeminências ósseas dos membros inferiores direito e esquerdo dos participantes. As variáveis dependentes foram: velocidade da corrida de aproximação; distância do pé de suporte para a bola; ângulo de aproximação para a bola; distância do participante para a bola; velocidade da bola; e comprimento e largura do passo durante a corrida de aproximação. As variáveis foram comparadas através de análise de variância (ANOVA) com medidas repetidas e com fator... (Resumo completo, clicar acesso eletrônico abaixo)

Crescimento de apatita na superfície da liga Ti-25Ta empregando dois tipos de tratamento de superfície: biomimético e deposição de polímero por eletrofiação

Titanium and its alloys has been widely used as materials for metallic biomaterials implants are usually employed to restore the hard tissue function, being used for artificial joints and bones, synthetic plates, crowns, dental implants and screws . Objective of this work was the surface modification of Ti-alloy 25Ta from biomimetic surface treatment of employment and deposition of polymer by electrospinning. The league was obtained from the fusion of the pure elements in the arc furnace with controlled atmosphere. The ingots were subjected to heat treatment, cold forged and sectioned discs with 13 mm diameter and 3 mm thick. Two surface treatments was evaluated, biomimetic and electrospinning with PCL fiber. The biomimetic treatment was performed involving alkaline treatment for three molarities 1.5M, 3M and 5M with immersion in SBF. The electrospinning was performed using PCL polymer alloy surface after the alkali treatment Ti25Ta 1M. For this group the polymer coated surfaces were immersed in calcium phosphate containing solution for immobilization of apatite. The results were compared with previous studies using surface treatment group to verify hydroxyapatite formation on the sample surface and it is concluded that the best condition is biomimetic treatment with 5M alkali treatment and heat treatment at 80 ° C for 72 hours

Resistência à tração de coroas de NiCr cimentadas sobre munhões de liga de titânio, com 4 diferentes tipos de cimentos

In this work of tensile strength was evaluated the efficacy of 4 cements (S. S. White zinc phoshate, Ketac Cem Easymix glass ionomer, RelyX Luting 2 composite resin/glass ionomer and Panavia 21 TC special acrylic resin) used to fix NiCr crowns to usinated titanium alloy abutments. Were used 40 abutments distributed in groups of 10 elements, to each material. The mechanical essays were developed at a MTS 810 universal machine, adjusted to a 0.5 mm/m velocity. The ANOVA applied to data pointed out the existence of significant differences between groups; the subsequent Tukey´s test (p<0.05) also detected significant differences, except at comparisons of phosphate versus RelyX and phosphate versus Ketac Cem. The better performance was presented by Panavia 21 (1,127.996 N); RelyX (478.197 N) showed itself similar only to phosphate (430.662 N), wich had a performance similar to that of Ketac Cem (227.705 N).

Estudo comparativo da inclinação do plano oclusal de modelos para cirurgia ortognática montados em dois tipos de articuladores semi-ajustáveis

Purpose: The aim of this study was to compare occlusal plane angulation measured in two different types of semi-adjustable articulators with that obtained on the lateral cephalometric radiograph. Materials and Methods: 20 patients due to undergo orthognathic surgery had dental casts mounted in two different types of semi-adjustable articulators through face bow transfer from the position of the maxilla and occlusal recording to the mandible. After mounting, the inclination of the occlusal plane in the articulators was measured and compared with the inclination measured at on both articulators and compared with the inclination measured on the lateral cephalometric radiographs and between the articulators themselves. The results obtained werestatistically analyzed. Results: Mean angulation values for the Bio Art (7.55º) and Kavo (-5.70º) articulators differ by 13.25º, which is statistically significant (p=0.00). When individually compared to the lateral cephalometric radiograph (5.075º), the Bio Art articulator showed more similar angulation values, with a difference of 2.475º, while the Kavo articulator presented a difference of 10.775º. Conclusion: Neither of the models of semi-adjustable articulators accurately reproduced the inclination of the maxillary occlusal plane of patients with dentofacial deformities; the difference between the two articulators tested and the lateral cephalometric radiograph was lower for the Bio Art than for the Kavo articulator.

Tratamento estético periodontal: revisão de literatura sobre alguns tipos de cirurgias

Currently, periodontal aesthetics has been prized for harmony of the smile. The clinical crown lengthening, gingival excess or altered passive eruption, is effectively corrected by periodontal surgery. The purpose of this paper is to show, through a literature review, some types of surgery on clinical crown lengthening and root coverage. Clinical crown lengthening is done to Change the size of the anterior teeth and to optimize the cosmetic result of treatment with new coronal restoration and other cosmetic dental care. In general, the treatment plan and the choice of operative technique begin with careful clinical examination. Recessions tissue can be defined as a displacement of the gingival margin toward the junction mucogingival exposing the root surface. These, when present, impacting on patient comfort by providing the occurrence of cervical dentin hypersensitivity, and the esthetic, the amendment of the gum line. Successful treatment of recessions is based on knowledge of its etiology and assessment of predictability of surgical techniques that aim to root coverage. Through literature review, we can conclude that the types of surgery most often used are: 1) to increase the clinical crown, gingivectomy, flap surgery and gingivoplasty osteotomy, and 2) for root coverage, the use will depend on the amount of gum keratinized and especially the classification of Miller.
