25. Análise da adição de resíduo oriundo do tratamento de esgotos em massa cerâmica utilizada para fabricação de telhas
Sludge of Wastewater Treatment Plants (WTPs) disposal is a problem for any municipality, for this reason the amount of sludge production is now a key issue in selecting treatment methods. It is necessary to investigate new applications for this waste type, due to the restrictions imposed by the environmental organs. The raw materials used in the Red Ceramic,

26. The Matrix Product Ansatz for integrable U(1)N models in Lunin-Maldacena backgrounds
We obtain through a Matrix Product Ansatz (MPA) the exact solution of the most general N-state spin chain with U(1)N symmetry and nearest neighbour interaction. In the case N = 6 this model contain as a special case the integrable SO(6) spin chain related to the one loop mixing matrix for anomalous dimensions in N = 4 SYM, dual to type IIB string theory in t

29. Comparative study of hydrocarbon oxygenation with ironchlorins and ironporphyrins as catalysts in homogeneous and heterogeneizated systems / Estudo comparativo da oxigenação de hidrocarbonetos com ferroclorinas e ferroporfirinas como catalisadores em meio homogêneo e heterogeneizados
In this work, the cyclohexane oxidation and the (Z)-cyclooctene epoxidation with iodosylbenzene (PhIO) e H2O2 as oxidants were studied. A comparison between fluorinated FeIIIchlorins and FeIIIporphyrins, [Fe(TFPCMG)]Cl, [Fe(TFPCMGCH3)]Cl2, [Fe(TFPP)]Cl, [Fe(TF4TMAPP)](CF3SO3)5 as catalysts was made either in solution or supported in silica matrices via eletr

31. Caracterização fisico-química de adobe estabilizado com amido de mandioca
Due to the high habitational Brazilian shortage, traditional technologies of earth construction and constructive elements production have been rescue, having the soil as a principal raw material. Between these traditional technologies, there are the adobes, which consist of soil blocks with regional variable size. The soil material is removed, humidified, tr

33. Avaliação comparativa pelos testes micropush-out e micro-cisalhamento da resistência adesiva de restaurações diretas de resina composta usando diferentes sistemas adesivos
The bond strength may be influenced by the different composition and manipulation of the adhesive systems, the dentin structure and the method of evaluation. After exposure of the occlusal dentin surface 160 third human molars were divided in 2 groups (n=80) for the micropush-out (μPBS) and microshear (μSBS) bond strength tests. For the μPBS,

35. Gênese, classificação e mapeamento de solos desenvolvidos de rochas pelíticas em áreas cultivadas com eucalipto em Minas Gerais / Genesis, classification and mapping of soils developed from pellitic rocks in areas cultivated with eucalyptus in Minas Gerais
Because the demand for arable areas has turned very intense in the last years, soils then considered as not appropriate to agricultural use are now being revalued and studied in order to use them for forest plantings, to example of Cambisols developed from pellitic rocks of Bambui Group. In reason of the expressiveness of these soils, usually associated Lato
