13. Estudo comparativo do padrão cefalométrico dos jovens mestiços nipo-brasileiros - grandezas tegumentares e esqueléticas / Comparative study of the cephalometric norms for Japanese Japanese-Brazilian descents skeletal and soft tissue measurements
Introduction: Remaining the diverse population in Brazil, the different ethnic groups can present unique skeletal and soft tissue measurements. Studies must be established to support orthodontics diagnostic and treatment plans between different races and different standards. Objective: Obtain mean normal values to soft tissue and skeletal cephalometric varia

14. AVALIAÃÃO DO REVESTIMENTO A BASE DE LIGA DE NÃQUEL EM AÃO ESTRUTURAL, EMPREGANDO O METAL DE ADIÃÃO ERNiCrMo-3 ATRAVÃS DA SOLDAGEM MIG/MAG / EVALUATE OF NICKEL WELD OVERLAY IN STRUCTURAL STEEL, WITH EMPLOYMENT OF GMAW ERNiCrMo-3 ELECTRODE.
The use of nickel alloy cladding components could be more frequently in petroleum industry. The crescent naphthenic corrosion and high molecular weight of national petroleum contribute for needs of materials with more resistance to corrosion, to temperature and to pressure. At this way, how part of systematic study, this work pretends to define operational r

15. Métodos para aproximação poligonal e o desenvolvimento de extratores de características de forma a partir da função tangencial
Whereas manually drawn contours could contain artifacts related to hand tremor, automatically detected contours could contain noise and inaccuracies due to limitations or errors in the procedures for the detection and segmentation of the related regions. To improve the further step of description, modeling procedures are desired to eliminate the artifacts in

16. Cephalometric study of skeletal, dental and soft tissue structures in white, black and afrocaucasian young Brazilian descents with normal occlusion / Estudo cefalométrico das estruturas esqueléticas, dentárias e tegumentares, em jovens brasileiros, leucodermas, feodermas e melanodermas, com "oclusão normal"
Actually, metropolitan areas have diverse populations, with a need to recognize that a standard of facial esthetics might not be appropriate when making orthodontics diagnostic and treatment plans for patients from various racial and ethnic backgrounds that migrated to distinct geographic bounds. With the purpose of using a specific cephalometric standard fo

17. AVALIAÇÃO CEFALOMÉTRICA DA ESTABILIDADE DO TRATAMENTO COM O REGULADOR DE FUNÇÃO FRÄNKEL-2 / Cephalometric estability evaluation of the treatment with Fränkel-2 Functional Regulator appliance
The aim of this study consisted of comparing dental, skeletal and soft tissue effects promoted by Frankel-2 functional regulator with a control group, besides observing the stability of those effects, in an average post-treatment period of 7.11 years. The sample had a total of 90 lateral cephalometric radiographs, with 54 cephalometric radiographs of 18 FR-2

18. Effects of the use of Mandibular Protraction Appliance and Jasper Jumper in the treatment of Class II malocclusion / Efeitos do Jasper Jumper e do aparelho de protração mandibular no tratamento da má oclusão de classe II
The objective of this study was to compare the effects of the treatment of Class II malocclusion with the Mandibular Protraction Appliance (MPA) and the Jasper Jumper, associated with fixed orthodontic appliances. The sample used comprised 71 subjects, divided into three groups: Group 1, with 24 patients at a mean initial age of 12.36 years, treated with the

19. Environmental determinism and stochasticity in an undertory community of the Atlantic Forest / Determinismo ambiental e estocasticidade em uma comunidade do sobosque da Floresta Atlantica
Both determinism and stochastic process are important to community organization and composition, although environmental determinism increasing in harsh habitat has been recently hypothesized. We aim to test this hypothesis in an understory community of the Atlantic rain forest in Ubatuba, São Paulo State, SE Brazil. We sample plants taller than 30 cm, with

20. O Teorama da Convexidade do Mapa do Momento
In this dissertation we presented the Atiyah-Guillemin-Sternberg convexity theorem about the image of the moment map in the case of Hamiltonian torus action on compact connected symplectic manifold. This result gives, in certain sense, a generalization to Schur theorem about relationship between eigenvalues and diagonal entries of Hermitian matrix. With this

21. ANÁLISE CEFALOMÉTRICA COMPARATIVA ENTRE CRIANÇAS RESPIRADORAS BUCAIS E NASAIS / Comparative cephalometric analysis between mouth breathing and nose breathing children
There are several controversies on the real interference from breathing on craniofacial growth. This study evaluated the possible relationship of the influence of breathing pattern with cephalometric variables: 1) sagittal skeletal variables: convexity of point A, facial depth, maxillary depth and mandibular body length; 2) vertical skeletal variables: lower

22. Tooth abnormalities, soft tissue changes and craniofacial morphology in patients with velocardiofacial syndrome and G/BBB syndrome / Disgenesias dentárias, alterações de tecido mole e morfologia craniofacial em pacientes com síndrome velocardiofacial e síndrome G/BBB
This study investigated the prevalence of tooth abnormalities, soft tissue changes and cephalometric analysis in patients with velocardiofacial syndrome and G/BBB syndrome. The presence of tooth abnormalities was evaluated in patients older than six years; cephalometric analysis was conducted on lateral cephalograms obtained before any orthodontic interventi

23. Estratégias de Hedge. Investimentos em mercados emergentes: as estratégias de Hedge pela duration e pela convexidade - a "trava borboleta" - são eficientes para os títulos da dívida externa brasileira?
A pesquisa objetiva testar empiricamente, se as estratégias de imunização pela duration e pela convexidade a Trava Borboleta utilizadas no mercado internacional como instrumentos de hegde para a variação de taxas de juros em títulos, são eficientes quando aplicadas aos títulos emitidos em dólares pelo governo brasileiro no mercado global os Brazilia

24. Fotografia e cubos : o fotográfico e o minimalismo
Most of the theories related to the photographic image have treated photography as an object of conventional research. The search for the specificity of the media was the tonic of the most important debates. In 1990, releasing a compilation entitled The photographic, the theoretic and historian of the art Rosalind Krauss observes that authors like Walter Ben
