25. Crystal structures of 5-chloro-2-methoxybenzoates of Mn(II), Co(II), Ni(II) and Zn(II)
The crystal and molecular structures of [bis(5-chloro-2-methoxybenzoate)tetraaquamanganese(II)], [pentaaqua(5-chloro-2-methoxybenzoato)cobalt(II)] (5-chloro-2-methoxybenzoate), [pentaaqua(5-chloro-2-methoxybenzoato)nickel(II)] (5-chloro-2-methoxybenzoate) and [aquabis(5-chloro-2-methoxybenzoate)zinc(II)] monohydrate were determined by a single-crystal X-ray

26. A ressurgência de classes de equivalência e os efeitos da opção de resposta default
Since initial studies, in 1980 decade several researches were carried through on the Behavior Analysis field with the objective of investigating this subject. The results of these researches are conflicting and generate implications as much practical, as for the theoretical definition of the resurgence concept. An important question related to the studies of

27. Distribuição das tensões geradas em implantes interconectados com barra dolder, após solda a laser
The Implant-retained prostheses need passivity and justness in their settlement, which are considered prerequisites for the osseointegration success. To minimize distortions and to promote passive settlement it is used the cut and solder of the piece. This work investigated, through photoelasticity, the distribution of stress generated by implants interconne

28. Efeito da terapia miofuncional em pacientes com paralisia facial de longa duração associada à aplicação de toxina botulínica / Effect of the muscular-function therapy in patients with long-standing facial paralysis associate to the botulinum toxin application
INTRODUCTION: The facial paralysis is constraining so much of the functional point of view as aesthetic. This research had for goal verified the myofunctional therapy effect in patients with long-standing facial paralysis associate to the botulinum toxin application. METHODS: Twenty-five patients were treated, divided into two groups. The patients from the g

29. Synthesis and Structural Analysis of New Coordination Polymers involving Seleninatos of Alkaline and Alkaline Earth Metals / Síntese e Análise Estrutural de Novos Polímeros de Coordenação Envolvendo Seleninatos de Metais Alcalinos e Alcalinos Terrosos
Seven new compounds involving the phenylseleninato ligand and alkaline and alkaline earth metals were obtained in this work: poly-phenylseleninato lithium(I) (1), catena-polybis(aqua)-phenylseleninato sodium(I) (2), poly-phenylseleninato potassium(I) (3), polytetraquis(aqua)-bis(phenylseleninato) magnesium(II) (4c), catena-poly-bis(phenylseleninic acid)-bis(

30. Spherical codes with cyclic symmetries / Codigos esfericos com simetrias ciclicas
Euclidean spherical codes with symmetries are orbits of finite orthogonal matrix groups. These codes are also known as group codes. ln this work, the commutative group codes in even dimensions are viewed on flat tori, which are submanifolds of the sphere. Also, if the matrix group is cyclic, the generated code lies on a knot which wraps around a torus. If th

31. Avaliação de assimetria nas arcadas dentárias de indivíduos com oclusão normal e má oclusão de Classe II / Evaluation of dental arch asymmetries in individuals with normal occlusion and Class II malocclusion
The objective of this study was to evaluate the dental arch asymmetrys degree in individuals with normal occlusion and Class II malocclusion and to investigate the sexual dimorphism presences in these individuals. 180 pars of study models were measured with a new appliance designed for analysis of dental arch asymmetries. These models were divided in three g

32. PREVALENCE OF ORAL LESIONS, AND PLAQUE, GINGIVAL, MARGINAL LINE CALCULUS INDEX AND PROBING DEPTH IN PATIENTS UNDER DIALYSIS AND KIDNEY TRANSPLANTS / Prevalência das manifestações bucais e dos índices de placa, gengival, de ocupação marginal e profundidade de sondagem em pacientes sob diálise e transplantados renais
Chronic renal failure (CRF) is a renal structural alteration which implies in the reduction or limitation of the kidney ability glomerular filtration. The CRF treatment includes hemodialysis or peritoneal dialysis to substitute glomerular filtration while a renal transplant, which is a definitive treatment, can be done. Oral lesions and secondary periodontal

33. Comportamentos repetitivos, interesses restritos e obsessões em individuos com transtorno global de desenvolvimento
Pervasive development disorders are psychiatric pathologies that affect children, and are usually severe and of chronic evolution. With a diagnostic based on a precocious beginning and on compromising the three mental functioning areas (mutual social interaction, language and communication and creative ability), it has in childhood autism and in Asperger s s

34. Finite Groups and Symmetry Breaking in the Genetic Code / Grupos finitos e quebra de simetria no código genético
In this work we solve the problem of classifying the possible symmetry breaking schemes based on simple finite groups that reproduce the degeneracies of the genetic code, thus contributing to the search for algebraic models that describe the evolution of the genetic code, initiated by Hornos &Hornos.

35. Coherent states: the symplectic goup and generalizations / Estados coerentes: o grupo simplético e generalizações.
The subject of the Thesis was the aplication of the coherent states theory to non-trivial quantum systems. Starting from the general definition of coherent states for compact Lie groups, we made a detailed investigation of the construction of these states and its properties in the case of the unitary symplectic group Sp(4), which is extremely important in bo

36. Positively curved 6-manifolds with simple symmetry groups
Seja M uma 6-variedade compacta, simplesmente conexa de curvatura sectional positiva. Se a identidade componente do grupo de isometria contém um subgrupo de Lie simples, provamos que M é difeomórfico de uma das 5-variedades listadas no Teorema A.
