1. Portable model for vasectomy reversal training
ABSTRACT Objectives To validate an experimental non-animal model for training of vasectomy reversal. Materials and Methods The model consisted of two artificial vas deferens, made with silicon tubes, covered by a white resin, measuring 10 cm (length) and internal and external diameters of 0.5 and 1.5 mm, respectively. The holder of the ducts is made by a

2. Three-dimensional analysis of an orthodontic delta spring
INTRODUCTION: The purpose of this study was to analyze the force system, moment-force ratios (M/F) and von Mises stresses in an orthodontic delta spring using a 3D finite element model. The M/F ratio produced by an orthodontic spring is related to the different types of tooth movement that are likely to occur in the sagittal and occlusal planes. METHODS: Ana

3. Caracterização e expressão do gene SERK durante a indução de embriogênese somática em soja / Characterization and expression of SERK gene during induction of somatic embryogenesis in soybean
Somatic embryogenesis is a useful tool for plant propagation and a suitable model system for deciphering early events during embryo development. Molecular and genetic studies focused in plant development have reported the involvement of SERK (Somatic Embryogenesis Receptor Kinase) gene in the acquisition of embryogenic competence. In order to increase the ef

4. Modeling and rendering of real environments
The use of detailed geometric models is a critical factor for achieving realism in most computer graphics applications. In the past few years, we have observed an increasing demand for faithful representations of real scenes, primarily driven by applications whose goal is to create extremely realistic experiences by building virtual replicas of real environm

5. Radiative transfer model for regular and discontinuous canopies (GRART): application in tree coffee canopies / Modelo de transferência radiativa para dosséis descontínuos regulares (GRART): aplicação para dosséis de café
Regularly displaced discontinuous plant stands such as coffee tree stands, citrus orchards, eucalyptus forests and annual crops at the beginning of their phenological cycle (row structured) are known as highly anisotropic remote sensing targets. Operational parameter estimate upon this kind of remote sensing targets requires a physically-based canopy reflect

6. A methodology for development augmented reality applications using mobile phones and sensors devices. / Uma metodologia para o desenvolvimento de aplicações de realidade aumentada em telefones celulares utilizando dispositivos sensores.
Handheld Augmented Reality or Handheld AR is the implementation of Augmented Reality (AR) systems into handheld devices. Handheld AR applications use the handheld devices camera to recognize markers (inserted into the environment). This process enables data entry into AR system. The response generated for these applications are presented as virtual images (3

7. Determinação de órbita e manobras utilizando GPS e motor com baixo empuxo / Orbit determination and autonomous maneuver using GPS and low thrust
The Global Positioning System (GPS) is a satellite navigation system that allows the users to determine 3D positioning and the time with high precision. Its main purposes are: aid to radionavigation in three dimensions with high precision positioning, navigation in real time, global coverage and quick acquisition of data sent by the GPS satellites. In this w

8. Reading: a teaching proposal to students from the second grade of elementary school by the educational software / Leitura: uma proposta de ensino a alunos de segunda série do ensino fundamental por meio de software educativo
The schooling success in the initial grades of elementary school is an important factor for the satisfactory development in the school process, in view on the fact; this is the period that necessary academics repertoires to learning of all the contents that surround the schooling environment are taught. The difficulties in learning of reading have been studi

9. Detecção condutométrica sem contato: uma nova ferramenta para monitoramento de interações biomoleculares em microssistemas analíticos / Contactless conductivity detection: a new tool for monitoring biomolecular interactions on analytical microsystems
The study reported in this thesis shows the application of a capacitively coupled contactless conductivity detection (C4D) for monitoring biomolecular interactions on analytical microsystems. Initially, the analytical performance of the microsystems fabricated in glass, poly(dimethylsiloxane) (PDMS) and polyester-toner (PT) was investigated in order to choos

10. Nutrition, growth, and growth modeling of eucalypt stands submitted to distinct water and nutrient availability / Nutrição, crescimento e sua modelagem em povoamentos de eucalipto em resposta à disponibilidade de água e nutrientes
The eucalypt culture in Brazil has a huge economical, environmental and social importance. In highly weathered soils of tropical regions, the maintenance of adequate flows of water and nutrients is fundamental to sustain yields and, therefore, the competitiveness of the forest sector in the international market. Evaluating and understanding how the water and

11. Avaliação da influência da distribuição de tamanho de partículas e do binômio velocidade/tempo de detenção na zona de reação no desempenho da flotação com emprego de sonda ultra-sônica e de técnica de análise por imagem / Analysis of particles distribution size and the pair velocity/hydraulic residence time in the reaction zone performance of a flotation unit by using ultrasonic probe and image analysis
This work investigated the performance of a dissolved air flotation (DAF) pilot plant, used to treat drinking water containing 05 Tu and 50 Cu. The particles (micro-bubbles and flocs) and hydraulic characteristics were taken into account. The focus was given in the reaction zone as hypothesized by Realis mathematic model (REALI, 1991). An image analyses was
