Estudo da viabilidade do sistema LZAS para uso como selante de PaCOS

Cells the solid oxide fuel are systems capable to directly convert energy of a chemical reaction into electric energy in clean, quiet way and if its components in the solid state differentiate of excessively the techniques for having all. Its more common geometric configurations are: the tubular one and to glide. Geometry to glide beyond the usual components (anode, cathode and electrolyte) needs interconnect and sealant. E the search for materials adjusted for these components is currently the biggest challenge found for the production of the cells. The sealants need to present chemical stability in high temperatures, to provoke electric isolation, to have coefficient of compatible thermal expansion with the excessively component ones. For presenting these characteristics the glass-ceramics materials are recommended for the application. In this work the study of the partial substitution of the ZrO2 for the Al2O3 in system LZS became it aiming at the formation of system LZAS, this with the addition of natural spodumene with 10, 20 and 30% in mass. The compositions had been casting to a temperature of 1500°C and later quickly cooled with the objective to continue amorphous. Each composition was worn out for attainment of a dust with average diameter of approximately 3μm and characterized by the techniques of DRX, FRX, MEV, dilatometric analysis and particle size analysis. Later the samples had been conformed and treated thermally with temperatures in the interval between 700-1000 °C, with platform of 10 minutes and 1 hour. The analyses for the treated samples had been: dilatometric analysis, DRX, FRX, electrical conductivity and tack. The results point with respect to the viability of the use of system LZAS for use as sealant a time that had presented good results as isolating electric, they had adhered to a material with similar α of the components of a SOFC and had presented steady crystalline phases

Estudo da viabilidade técnica para obtenção de superfície duplex em aço inoxidável martensítico AISI 410 através do processo de deposição a plasma por gaiola catódica

The technique of plasma nitriding by the cathode cage mainly stands out for its ability to produce uniform layers, even on parts with complex geometries. In this study, it was investigated the efficiency of this technique for obtaining duplex surface, when used, simultaneously, to nitriding treatment and thin film deposition at temperatures below 500°C. For this, were used samples of AISI 41 0 Martensitic Stainless Steel and performed plasma treatment, combining nitriding and deposition of thin films of Ti and/or TiN in a plasma atmosphere containing N2-H2. It was used a cathodic cage of titanium pure grade II, cylindrical with 70 mm diameter and 34 mm height. Samples were treated at temperature 420ºC for 2 and 12 hours in different working pressures. Optical Microscopy (OM), Scanning Electron Microscopy (SEM) with micro-analysis by Energy Dispersive Spectroscopy (EDS), X-Ray Diffraction (XRD), Atomic Force Microscopy (AFM) and analysis of Vickers Microhardness were used to investigate coating properties such as homogeneity and surface topography, chemical composition, layer thickness, crystalline phase, roughness and surface microhardness. The results showed there is a direct proportionality between the presence of H2 in plasma atmosphere and the quantity of titanium in surface chemical composition. It was also observed that the plasma treatment at lowpressure is more effective in formation of TiN thin film

Influência das tensões tectônicas na permeabilidade da formação Açu - Bacia Potiguar

The behavior of the fluid flux in oil fields is influenced by different factors and it has a big impact on the recovery of hydrocarbons. There is a need of evaluating and adapting the actual technology to the worldwide reservoirs reality, not only on the exploration (reservoir discovers) but also on the development of those that were already discovered, however not yet produced. The in situ combustion (ISC) is a suitable technique for these recovery of hydrocarbons, although it remains complex to be implemented. The main objective of this research was to study the application of the ISC as an advanced oil recovery technique through a parametric analysis of the process using vertical wells within a semi synthetic reservoir that had the characteristics from the brazilian northwest, in order to determine which of those parameters could influence the process, verifying the technical and economical viability of the method on the oil industry. For that analysis, a commercial reservoir simulation program for thermal processes was used, called steam thermal and advanced processes reservoir simulator (STARS) from the computer modeling group (CMG). This study aims, through the numerical analysis, find results that help improve mainly the interpretation and comprehension of the main problems related to the ISC method, which are not yet dominated. From the results obtained, it was proved that the mediation promoted by the thermal process ISC over the oil recovery is very important, with rates and cumulated production positively influenced by the method application. It was seen that the application of the method improves the oil mobility as a function of the heating when the combustion front forms inside the reservoir. Among all the analyzed parameters, the activation energy presented the bigger influence, it means, the lower the activation energy the bigger the fraction of recovered oil, as a function of the chemical reactions speed rise. It was also verified that the higher the enthalpy of the reaction, the bigger the fraction of recovered oil, due to a bigger amount of released energy inside the system, helping the ISC. The reservoir parameters: porosity and permeability showed to have lower influence on the ISC. Among the operational parameters that were analyzed, the injection rate was the one that showed a stronger influence on the ISC method, because, the higher the value of the injection rate, the higher was the result obtained, mainly due to maintaining the combustion front. In connection with the oxygen concentration, an increase of the percentage of this parameter translates into a higher fraction of recovered oil, because the quantity of fuel, helping the advance and the maintenance of the combustion front for a longer period of time. About the economic analysis, the ISC method showed to be economically feasible when evaluated through the net present value (NPV), considering the injection rates: the higher the injection rate, the higher the financial incomes of the final project

Aspectos morfológicos do fruto, da semente e desenvolvimento pós-seminal de faveira (Clitoria fairchildiana R. A. Howard. - Fabaceae)

O presente trabalho teve por objetivo descrever a morfologia dos frutos, das sementes e o desenvolvimento pós-seminal de faveira (Clitoria fairchildiana R. A. Howard. - Fabaceae). Os frutos e as sementes foram caracterizados quanto à forma e dimensões. Periodicamente, unidades representativas de cada fase de germinação foram retiradas para as descrições morfológicas. Os frutos são do tipo legume, deiscentes e de coloração marrom. As sementes são exalbuminosas, de forma orbicular e achatada, com tegumento de coloração castanho-esverdeada. O hilo tem forma elíptica, homocromo e de tamanho pequeno em relação à semente. Os cotilédones são livres, de coloração verde, maciços e plano-convexos e o embrião é invaginado. O início do desenvolvimento pós-seminal é marcado pelo rompimento do tegumento e emissão da raiz primária, glabra, de coloração amarelo-esverdeada e de forma cilíndrica. Posteriormente, observa-se o desenvolvimento das raízes secundárias, levemente esbranquiçadas, curtas e filiformes. em seguida, o crescimento do hipocótilo proporciona a emergência dos cotilédones e da plúmula acima do substrato. O epicótilo alonga-se e, em seguida, observa-se a expansão dos eófilos, simples, opostos, com tricomas simples e esparsos, pecíolos curtos com estípulas em sua base. Posteriormente ao desenvolvimento dos eófilos, ocorre a formação do segundo par de folhas, alternas, trifolioladas, estipuladas e com estipelas na base dos peciólulos.

Apoio pedagógico, ação coletiva e diálogo: tramas da formação continuada em educação inclusiva

This work detaches the importance of the continued formation of the educators in terms of the inclusive educational process, pointing as basic elements the continued formation of the educational professionals. In this direction, it points and it defends the dialogue in the perspective of David Bohm, with interfaces of the freireanas ideas, as a methodological resource of action that allows the organization of strategies of collective and effective pedagogical support in inclusive schools, in the same time articulates the continued formation of the professionals in education. Characterized as research in a dialogical action with collective participation and collaboration, it counted with the participation of 87 educators, between professors, pedagogical, managing coordinators and specialists of special education in two schools of the state and municipal public system of Natal/RN. The results had pointed with respect to the viability of the dialogue as articulated methodological tool of the continued formation in service, when providing the establishment of personal and professional relationship between the educators, favoring the discursive enjoyment of the lived experiences, allows the organization of strategies of collective and effective pedagogical support in the scholar environment. On the basis of these results, this work also points to some items to reflections as the reorganization of the Secretariats and the schools, in the direction to brighten up the fragmentation and the discontinuity of the pedagogical actions evidenced and to instigate a process of changes that has glimpsed the professional development of the educators through its continued formation in service and the improvement of the school in the way of the concretization of an education directed toward the acceptance, respect and attendance the diversity of its pupils, as detaches the official documents and the studies on the inclusive education

Utilização do teste de raios - x na avaliação dos efeitos da dessecação e infestação em diásporos de Canela-Batalha - Cryptocarya aschersoniana Mez (Lauraceae)

No presente trabalho, objetivou-se avaliar os efeitos da dessecação e identificar lesões por predação por insetos, em diásporos de canela-batalha (Cryptocarya aschersoniana Mez.), utilizando-se testes de raios X. Os danos provocados pela dessecação foram dimensionados nas imagens e associados à formação de plântulas. Diásporos recém-beneficiados (45 % de umidade e 37 % de germinação) foram colocados para secar em sala climatizada (20 ºC e 60 % UR), dentro de bandejas plásticas em camada única. Posteriormente, com o intuito de acelerar o processo de secagem, foram colocados em caixas de secagem com solução saturada de hidróxido de sódio (28 % UR) e amostrados com 45, 37, 35, 31 e 26 % de umidade. Para as radiografias, utilizou-se a intensidade de radiação de 40 kVp e tempo de exposição de 1,5 minutos. Posteriormente, as radiografias foram fotografadas e as imagens analisadas em computador, sendo medido o afastamento entre o endocarpo e a semente. As sementes foram classificadas em sementes intactas, sementes com afastamento parcial, sementes com afastamento total e sementes predadas. Os testes de germinação foram realizados sobre areia, em germinadores tipo Mangelsdorf a 25 ºC e luz branca constante. Pelos resultados, observa-se que a germinação é comprometida quando o teor de água das sementes fica abaixo de 26 %. Nesse ponto, o afastamento entre o endocarpo e a semente é de 0,65 mm. Houve uma correlação positiva entre a viabilidade das sementes, avaliada pelo teste de germinação, e o afastamento entre o endocarpo e a semente observado nas radiografias. A análise radiográfica possibilita identificar danos provocados por predação após infestação por insetos.
