13. Ex vivo analysis of apical human tooth in 3D sections using computed micro-CT / Análise ex vivo de cortes apicais de dentes humanos em 3D empregando microtomografia computadorizada
This ex vivo study aimed to investigate the apical anatomy of vital and necrotic human roots by microcomputed tomography (micro-CT). Thirty-five single or multirooted human teeth that had their roots separated totaling forty-one roots were carefully pre-selected and divided into two groups: vital pulp (VP) n = 21 and necrotic pulp (NP) n = 20. Both groups we

14. Um processo fotográfico em sobreposição no espaço urbano
A instalação de projeções no espaço urbano é o tema desta pesquisa, que aborda um processo de criação artística realizado no período 2002-2007. Construções arquitetônicas precárias e/ou abandonadas situadas em cidades brasileiras foram fotografadas e, posteriormente, retornaram às cidades como imagens projetadas sobre paredes de outras edifica

15. SimulaÃÃo do Desgaste Abrasivo via InteraÃÃes MÃltiplas / Using Multiple Interactions to Simulate Abrasive Wear
Abrasive wear is currently classified according to different particle dynamics: a) the sliding of active particles on the sample surface and b) the rolling of abrasives between the surfaces. The prevailing particle dynamics depends on the system features. In this thesis, instrumented laboratory tests are used to present a new methodology for the simulation o

16. Projeto e fabricação de nao-estruturas por litografa interferometrica / Design and fabrication of nano-structures by interforometric lithography
In this work the interferometric lithography technique was developed for recording periodic relief nano-structures, one and bi-dimensional, on silicon and glass substrates. In particular, the work is focused in two directions: the study of the profile of the structures recorded in photorresist, through the superimposition of interference light patterns, and

17. Participative processes in an indigenous community: political activism of the Ingarikó tribe motivated by environmental conservation in Mount Roraima National Park. / Processos participativos em comunidade indígena: um estudo sobre a ação política dos Ingarikó face à conservação ambiental do Parque Nacional do Monte Roraima
O presente estudo baseia-se na vivência do pesquisador como membro participante de assembléias realizadas e organizadas pelos índios Ingarikó, em 2005, em Roraima, especificamente na Terra Indígena Raposa Serra do Sol. Essas assembléias visavam discutir as alternativas de gestão do território ocupado pelo grupo Ingarikó, em função da dupla afetaç

18. Assessment of mandibular advancement surgery with 3D CBCT models superimposition / Avaliação da cirurgia de avanço mandibular por meio da superposição de modelos tridimensionais / Avaliação da cirurgia de avanço mandibular por meio da superposição de modelos tridimensionais / Assessment of mandibular advancement surgery with 3D CBCT models superimposition / Avaliação da cirurgia de avanço mandibular por meio da superposição de modelos tridimensionais / Assessment of mandibular advancement surgery with 3D CBCT models superimposition
Deslocamentos de côndilos e ramos acompanhando a cirurgia de avanço mandibular foram descritos, mas a influência destas mudanças na instabilidade pós-cirúrgica ainda é pouco conhecida. Limitações na avaliação quantitativa de deslocamentos cirúrgicos pelos métodos tradicionais podem ser superadas através da tomografia cone beam e ferramentas de

19. Estudo do imposex em muricÃdeos do gÃnero Stramonita (Mollusca: Gastropoda) no Nordeste do Brasil / Imposex in muricÃdeos study of the genus Stramonita (Mollusca: Gastropoda) in northeastern Brazil
Imposex consists of a superimposition of male sexual characteristics in female prosobranch molluscs exposed to organotin compounds (OCs) contamination. This contamination is caused by biocides present in antifouling paints used on boats all over the world. Since imposex leads to measurable characters, those have been used for biological-effect monitoring of

20. What controls verbal responses emitted when a give behavior is observed / O que controlaria respostas verbais diante de um comportamento observado
The tact is a verbal operant in which the response is emitted under control of an antecedent non-verbal stimulus and is maintained by generalized conditioned reinforcement. Technically, a verbal report and an explanation can be considered tacts. Among the tacts one emits, those in which the speaker behaves verbally under the control of another persons behavi

22. Clinical and experimental application of the percutaneous twitch superimposition technique for the study of human muscle activation.
The use of percutaneous stimulation for twitch superimposition in the human quadriceps has been compared with stimulation via the femoral nerve. It was found that the relationship between the extra force generated by the twitch and the level of voluntary contraction was independent of the percentage of the muscle stimulated. The technique was used to study a

23. Mitral incompetence and ventricular septal defects following non-penetrating injury.
A case of mitral incompetence and multiple ventricular septal defects following a non-penetrating chest injury is described. Cardiac injury was detected by electrocardiogram and by the appearance of a heart murmur in the second week after trauma. Superimposition of bacterial endocarditis seven years later caused cardiac decompensation and necessitated succes

24. Two types of confabulation.
Examples of confabulation in Korsakoff patients, Alzheimer-type dementing patients, and healthy subjects are discussed. It is argued that there may be two types of confabulation: spontaneous confabulation, which may result from the superimposition of frontal dysfunction on an organic amnesia, and provoked confabulation, which may reflect a normal response to
