2. Estudo experimental comparativo de métodos de diérese tecidual no tratamento endoscópico do divertículo faringo-esofágico / Experimental study comparing two methods of tissue diaresis for endoscopic treatment of pharingoesophageal diverticulum
The pharyngoesophageal diverticulum (PED), also known as cricopharyngeal or Zenker diverticulum (ZD), is a rare disease with estimated incidence ranging from 0.01% to 0.11% and more present in elderly patients, for whom a less invasive treatment can be desirable. Despite innovations in endoscopic equipment and accessories, bleeding and perforation occur in u

4. Novo método para assinatura e identificação de sinais de eletrocomunicação de peixes elétricos de campo fraco da espécie Gymnotus carapo / Novel method for signature and identification of electrocommunication signals of the weakly electric fish Gymnotus carapo
Desenvolvemos um método capaz de reconhecer assinaturas de descargas do órgão elétrico de peixes de campo elétrico fraco da espécie Gymnotus carapo. A assinatura de um peixe é computada com base no espectro de frequências de suas descargas, extraído por meio de uma transformada de Fourier, ou com base em uma análise tempo-frequência das mesmas, re

5. Comparison between experimental data and numerical modeling for the natural circulation phenomenon
The study of natural circulation phenomenon has been object of crescent interest in scientific community in recent years. The new generation of compact nuclear reactors uses natural circulation of the fluid as a residual heat removal cooling system in case of accident or shutdown. The objective of this paper is to present a comparison between experimental da

6. Desenho e construção de um UHV-STM / Design and construction of an UHV - STM
O estudo da estrutura de nanosistemas individuais requer o uso de equipamentos capazes de gerar imagens de sistemas com poucos átomos. No caso de nanopartículas metálicas produzidas por síntese química, uma questão relevante e ainda pouco estudada é a organização dos passivantes sobre sua superfície e como isso contribui para a definição de sua e

7. Eugène Bourdon y la evolución del manómetro
Eugène Bourdon is the almost unknown inventor of one of the instruments most known by engineers around the World. From its introduction around the middle of XIX century, the Bourdon manometer or tube has been the most employed instrument for measuring pressure at laboratory and industrial scales. Its appearance in the European market, following by that in A

9. Identificação dos limiares de lactato, ventilatórios e eletromiográficos em exercício resistido
Resistance training (RT) has been subject of several scientific studies, since its application not only for aesthetic purposes, but in health promotion and sports activities. To understand the determinants of physical performance is necessary to analyze biochemical, biomechanical and physiological phenomena triggered as a result of each physical activity pro

11. Stresses distributions of screws of the vertebral fixation systems submitted to pullout strength using plane transmission photoelasticity. / Distribuição de tensões de parafusos do sistema de fixação vertebral submetidos a arrancamento utilizando fotoelasticidade de transmissão plana
The treatment of spinal deformities, degenerative disease, injuries and tumors on the vertebral column often demand the accomplishment of the internal fixation. The pedicular screws arising enabled the accomplishment of column segmental instrumentation more stable and became a standard procedure in accomplishing surgeries of correction, deformities stabiliza

12. Définition et implémentation des corrections instrumentales de la mission spatiale CoRoT
CoRoT (Convection, Rotation and planetary Transits) is a space mission conceived to the stellar seismology and the search of extra solar planets. Both scientific programs are based on very high precision photometry and require long and uninterrupted observations. For the study of the stellar oscillations, the instrument must be able to measure periodic varia
