A produção do espaço rural no município de Ceará-Mirim

This research intended to study the process of production of the rural space in the municipal district of Little Ceará-Mirim, looking for to identify the transformations in him happened, above all in the last thirty years. Since the beginning of your historical formation, the area in study had as element modelador and transformer of the physiognomy of your territory the culture canavieira that printed in your economy and in your society marks of a powerful nobility. The sugar-cane is covered of a cyclical character facing acme phases and decadence, as the one that it happens at the present time. Simultaneously, the sphere rural cearimirinense is going by changes by the implantation of modern companies gone back to the papaya production destined to the internal market and more precisely to the external market. Of this context they also consist the supplying farms of this same product. In the group of the establishments in the rural landscape here analyzed, they still interfere the mixed farms, the ones that practice agriculture, the ones that were devoted to the livestock, as well as the farms and the ranches. Another innovation is the caprinocultura developed in modern molds, using the system voisin of pasture rodízio being constituted in a pioneering experience in Brazil. Of that reality they announce other elements, to example of the establishments, being configured as new forms of use of the soil. In the perspective of turning them productive, the challenge resides of overcoming the difficulties in them existent. The reality of the space in screen is replete of lacks in all the instances. It is inferred that the municipal district possesses an enormous potential, however the performance of the administrative components is seen as deficient. He becomes urgent that the municipal public power promotes changes, mainly in what it respects to the social area, with a better attendance to the rural communities, for them to act positively in the process of the development of this municipal district

Desenvolvimento territorial e a política nacional de água em Moçambique: o caso do distrito de Chibuto

The development has been a phenomenon in constant discussion today, whose fundamental importance should be to promote the welfare of humanity. Thus, the development becomes an element that adds political, economic, social and environmental values . In Mozambique the development model adopted by the State prioritizes the economic dimension, in this case favoring the growth of capitalist structure production. Thus , the basic conditions for human survival still leaves much to be desired and the Mozambican population in general and the district of Chibuto , in particular , continue to face several difficulties to have access to such conditions, and the lack of potable water is a that most of the problems afflicting this population . The water was always a factor related to the socio-economic development of the population, where great civilizations and major economic marks were always influenced by water availability, and today this feature is present in all sectors of production. In Mozambique, much effort has been made by the government, national and international organizations to enhance and guarantee the supply of potable and drinking water, and despite all this effort, most of the population does not have access to this precious resource. In this sense, this work presents an analysis of the effects of the National Water Policy in the study area, analyzes the shortage of potable water in the district of Chibuto, discusses the design and development contained in the official discourse of the state and, opposes the idea of human development. For such issues that help to understand the phenomenon under study, such as territory, public policy and criticism of hegemonic conception of development are addressed. To make the desired approach, we performed a characterization of the District of Chibuto, addressing the issue of poverty, with a brief discussion of this concept, from different approaches, and analyze the impact of the PARPA (Action Plan for the Reduction of Absolute Poverty) in fighting poverty in Mozambique, and became a description of the scenario of poverty and vulnerability in Chibuto district with the construction of Territorial Human Development Index. Research also brings up a discussion about territory and technicization which describes the senary of the water supply system in the District and territorial dynamics of Chibuto, from the analysis and description of existing structures and other technical objects that structure the territory under study. Thus, it was found that the development should be summarized in the satisfaction of human needs, and should be the cornerstone of the new type of development that is intended for the purpose of triggering urgently actions to overcome or combat bleak misery suffered by the majority of inhabitants of the District of Chibuto

Acupuntura: histórico, bases teóricas e sua aplicação em Medicina Veterinária

A acupuntura (AP) é uma técnica terapêutica empírica desenvolvida em uma cultura oriental e que utiliza pensamento mágico (linguagem pré-científica) em seu raciocínio. É uma terapia reflexa que utiliza a estimulação de pontos específicos do corpo com objetivo de atingir um efeito terapêutico ou homeostático. A AP preconiza que a saúde é dependente das funções psico-neuro-endócrinas, sob influência do código genético e de fatores extrínsecos como nutrição, hábitos de vida, clima, qualidade do ambiente, entre outros. O presente artigo faz uma breve revisão sobre a filosofia da AP, seus marcos históricos na China e no Ocidente, a história da AP veterinária no Brasil e no mundo. Também aborda a prática da AP, incluindo as formas de diagnóstico, a definição do protocolo de tratamento, os métodos de estimulação dos pontos, o agulhamento de animais, suas indicações, contra-indicações e reações adversas.

Tunnel technique with a surgical maneuver to increase the graft extension: Case report with a 3-year follow-up

Background: This article reports a clinical case with a 3-year follow-up in which a subepithelial connective tissue graft (SCTG) was used with the tunnel technique to treat multiple gingival recessions, and describes a technique used to enlarge the extension of the graft.Methods: A 41 -year-old female patient was referred for evaluation and treatment of maxillary multiple recessions. Following basic therapy, the plaque index was 23%, and the gingival index was 12%. Thus, SCTG with the tunnel technique was proposed to provide root coverage of Miller Class I recession on teeth #8 through #11 and a Miller Class III recession on tooth #12. After the donor area had been prepared, SCTG was removed and split cross-sectionally to lengthen it. The graft was placed through the tunnel and sutured.Results: Two weeks after the surgical procedure, the tissue color was nearly homogeneous with some reddish regions where the connective tissue was left uncovered, and there were no signs of incisions or suture marks. After 3 years of follow-up, the mean coverage of the recessions was 2.2 +/- 0.7 mm (74.2%), which corresponded to the gain of keratinized tissue. In addition, a gain in tissue thickness was observed.Conclusion: In a long-term evaluation, the tunnel technique with the elongated SCTG was used successfully for treatment of multiple gingival recessions with an increase of the soft tissue volume and gain of keratinized tissue.

CORRELATING THE CURVE DISTANCE BETWEEN THE DISTAL of THE CANINES TO THE COMBINED WIDTH of THE SIX ANTERIOR TEETH WHEN SELECTING DENTURE TEETH FOR DIFFERENT ETHNIC GROUPS

Statement of problem. To select the width of denture teeth, the distance between the marks indicating the location of the canines is usually measured around the curvature of the wax occlusal rim; however, most manufacturers' mold charts provide the measurements of the artificial 6 anterior teeth as if they were on a straight line.Purpose. The purpose of this study was to investigate whether the curve distance between the distal surfaces of the maxillary canines can be related to the combined width (straight measurement) of the 6 anterior teeth in 4 ethnic groups.Material and methods. Maxillary stone casts were obtained for 160 dentate subjects of 4 ethnic groups (40 whites, 40 blacks, 40 multiracial - descendants of white and black parents, and 40 Asians). The width of each maxillary anterior tooth was measured on the casts with sliding calipers. The combined width of the 6 anterior teeth (CW) corresponded to the sum of the width of each anterior tooth. The curve distance between the distal surfaces of the canines (CD) was measured by using dental tape and sliding calipers. The Pearson correlation coefficient and regression analysis were used to evaluate the relationship between CD and CW in each ethnic group (alpha=.05).Results. The mean CD and CW values (in mm) obtained were: whites (CD=52.12; CW=45.65); blacks (CD=56.10; CW=48.13); multiracial (CD=53.58; CW=46.54); and Asians (CD=53.29; CW=46.60). Significant (P<.001) correlations between CD and CW measurements were observed for all ethnic groups studied (whites, r=0.957; blacks, r=0.803; multiracial, r=0.917; and Asians, r=0.881). The following linear regression equations were obtained: whites [CD=1.1(CW)+0.3]; blacks [CD=0.95(CW)+9.3]; multiracial [CD=1.2(CW)-1.1]; and Asians [CD=1.0(CW)+5].Conclusions. The curve distance between the distal surfaces of the maxillary canines can be accurately related to the combined width of the 6 anterior teeth in the selection of denture teeth for the studied ethnic groups.

Biologia da reprodução de Mimosa bimucronata: uma espécie ruderal

Com o objetivo de estudar a biologia reprodutiva de Mimosa bimucronata, o presente estudo foi realizado em Botucatu e Cachoeira Paulista, SP, no período de novembro de 2003 a junho de 2005. Determinou-se o número de flores por glomérulo, sua duração, os eventos da antese e outras características florais, como tamanho, formato, coloração, odor, presença de néctar e localização de osmóforos. A receptividade do estigma e a viabilidade do pólen foram avaliadas. Flores foram examinadas e documentadas em microscópio eletrônico de varredura, após tratamento adequado. Foram feitos testes para a determinação do sistema reprodutivo, visando avaliar a dependência dos polinizadores. A presença de visitantes florais foi observada no campo, sendo registrada a quantidade de visitas e o comportamento dos visitantes, além do tempo médio de permanência dos visitantes junto às flores. O padrão de floração de M. bimucronata é anual. Os grãos de pólen encontram-se reunidos em políades compostas por oito células, o que pode ser interpretado como uma adaptação para minimizar o efeito da mistura das cargas de pólen depositadas sobre o diminuto estigma. A formação de frutos em condições naturais foi baixa e não ocorreu agamospermia. A morfologia das flores e das inflorescências permite o acesso aos recursos florais para uma ampla variedade de visitantes (Hymenoptera, Diptera e Coleoptera). A maioria das visitas foi realizada por abelhas (56,4%). Os resultados permitem considerar que, embora M. bimucronata seja dependente de vetores de pólen para sua reprodução, é espécie entomófila generalista e, portanto, bastante adaptada aos ambientes ruderais, onde sua ocorrência é predominante.

Tafonomia de biválvios em calcários oolíticos da formação Teresina (Bacia do Paraná, Permiano Médio, Prudentópolis, PR)

Herein, it is presented the first detailed taphonomic study on bivalve mollusk shells preserved in the oolitic limestones of the Teresina Formation (probably Kungurian-Roadian, Lower-Middle Permian) in the eastern margin of the Parana basin. The selected beds are located in two quarries (informally named PRU 1 and PRU 2) in Prudentopolis municipality (Center-South Parana State), and positioned approximately in the middle of the formation and probably in the Pinzonella illusa Zone. The PRU 1 limestone ([approximately]30 cm thick), which is partially silicified and intercalated with predominantly pelitic rocks, is classified as a bivalve oolitic grainstone. The basal contact is erosive and the top shows symmetrical ripple marks, which are draped by shale with mud cracks. There are two fining-upwards successions characterized by dense to dispersed packing of the shells, which are usually disarticulated, randomly oriented (many nested/stacked) and mixed with some Formapelitic intraclasts. Microhummocky cross-stratification occurs a little below the top of the bed. The PRU2 bed is classified as ooidbivalve rudstone[approximately] (~5 cm thick), where all shells are disarticulated and fragmented, showing dense packing. The bivalves probably inhabited a muddy substrate and were mixed (as parautochtonous and allochthonous bioclasts) with ooids during high-energy storm events, including posterior shell displacement as a result of bioturbation. Thus, the calcareous beds represent amalgamated proximal tempestites with a complex taphonomic history, strong temporal/spatial mixing of bioclasts and limited paleoecological resolution. They are a typical example of shell beds generated in a huge epeiric sea, which was not necessarily connected to the ocean and where very low depositional-slope gradient, very slow subsidence and minimum sediment accommodation space caused frequent sediment reworking by storm related processes.

Effects of forest fragmentation, anthropogenic edges and fruit colour on the consumption of ornithocoric fruits

We investigated effects of fruit colour (red, black or white), habitat (anthropogenic edges and forest interior) and fragment size on the removal of artificial fruits in semideciduous forests in south-east Brazil. Eight forest fragments ranging from 251 to 36,000 ha were used. We used artificial fruits, which were placed on shrubs between I and 2 m in height and checked after 48 and 96 h for peck marks in the fruits. All three variables affected the probability of consumption of our fruit models. Red and black fruits were statistically more pecked than the white fruits. The probability of fruit consumption was lower in the interior than at the edge and less in small than in large fragments. However, the decrease fruit consumption in small compared with large fragments was more accentuated for red and black fruits than for white fruits. Our results show that habitat reduction and edges affect the chances of a fruit being eaten by birds, which may ultimately affect plant fitness in forest fragments. (C) 2003 Elsevier B.V. Ltd.

Efeitos da autoclavação na velocidade e capacidade absorvente de cones de papel empregados em Endodontia

A presença de umidade no interior do sistema de canais radiculares, após o preparo biomecânico e sua desinfecção, pode influenciar no selamento apical e no êxito da obturação endodôntica. O objetivo deste trabalho foi avaliar a influência do número de esterilizações em autoclave, sobre a capacidade e velocidade de absorção dos cones de papel empregados em Endodontia. Foram analisados 440 cones de papel número 40, dos quais dez cones de cada marca comercial receberam de zero à dez ciclos de esterilização em autoclave (134°C/15 psi/15 minutos). Após cada ciclo de esterilização, os cones foram avaliados quanto a capacidade e velocidade de absorção de solução de hipoclorito de sódio a 1%. Os dados foram submetidos à análise estatística por meio dos testes da ANOVA (dois critérios) e Tukey (5%). Pôde-se concluir que, quanto à capacidade de absorção, os cones que sofreram menor influência dos diversos ciclos de esterilização em autoclave foram, em ordem decrescente: Tanari, Tanari cell pack, Conne e Diadent cell pack. Quanto à velocidade de absorção, os cones que obtiveram os melhores resultados foram: Tanari cell pack, Tanari, Conne e Diadent cell pack. A autoclavação mostrou-se um procedimento viável, em até 10 ciclos, apenas para a esterilização de cones de papel absorvente da marca Tanari utilizados em Endodontia.

Surface Passivation of Nanoporous TiO2 via Atomic Layer Deposition of ZrO2 for Solid-State Dye-Sensitized Solar Cell Applications

We report here the utilization of atomid layer deposition to passivate surface map states in mosoporous TiO2 nanoparticles for solid state dye sensitized solar cells based on 9,9'-spirobifluorene (spiro-OMeTAD). By depositing ZrO2 films with angstrom-level precision, coating the mesoporous TiO2 produces over a two-fold enhancement in short-circuit current density, as compared to a control device. Impedance spectroscopy measurements provide evidence that the ZrO2 coating reduces recombination lossed at the TiO2/spiro-OMeTAD interface and passivates localized surface states. Low-frequency negative capacitances, frequently observed in nanocomposite solar cells, have been associated with the surface-state mediated charge transfer from TiO2 to the spiro-OMeTAD.

Filmes na formação de futuros professores: educar o olhar

Neste artigo, trago parte de minha experiência como professora de futuros professores de Matemática quando ministrei a disciplina Didática, no ano de 2010. Socializo aqui algumas das práticas instituídas nesse contexto e que resgatam a potencialidade dos filmes e da escrita no processo formativo dos alunos. Problematizo a importância de assistir juntos a um filme, já que essa experiência estética possibilita promover o conhecimento, o sentimento e a ação. Trago a voz dos meus alunos, documentada nos registros semanais elaborados por eles, para dizer das marcas que os filmes deixaram no percurso formativo de cada um como futuros professores de Matemática. Ao resgatar essa prática, enfatizo a importância de educar o olhar na busca pela constituição de um professor comprometido com uma educação e uma sociedade mais justa e democrática.
