1. Study using a CFD approach of the efficiency of a roof ventilation closure system in a multi-tunnel greenhouse for nighttime microclimate optimization
ABSTRACT The thermal efficiency of naturally ventilated greenhouses is limited due to the permanent exchange of air through the vents, especially during the night hours. The objective of the work consisted in evaluating a system of inflatable air ducts that close the roof vents during the night as a strategy to reduce the energy loss during these hours. For

2. Concreto com borracha de recauchutagem de pneu para uso em pavimentação de baixo tráfego
RESUMO O aumento da demanda por veículos acarreta maior produção de novos pneus. No entanto, após o término de sua vida útil, eles se tornam um passivo ambiental de difícil descarte adequado, tanto pela demora em se decompor quanto por seu grande volume. Sua disposição inadequada causa grandes danos ao meio ambiente e favorece a proliferação de ve

3. ON AN INTEGRATED DYNAMIC CHARACTERIZATION OF VISCOELASTIC MATERIALS BY FRACTIONAL DERIVATIVE AND GHM MODELS
Abstract The passive vibration control of mechanical systems under unwanted vibrations can be accomplished in a very effective way by using devices incorporating viscoelastic materials. The design of such devices requires a broad knowledge of the dynamic properties of the employed viscoelastic material, usually supplied by adequate mathematical models. Among

4. Technique of Framework Cemented on Prepared Abutments to Obtain Passive Fit at Fixed Complete Denture: A 2-Year Follow-Up Report
A adaptação passiva de próteses implantossuportadas é fundamental para o sucesso da reabilitação devido à inexistência de ligamento periodontal em implantes osseointegrados. Inúmeras técnicas de confecção da infraestrutura destas próteses tem sido relatadas na literatura, algumas inacessíveis para os clínicos e laboratórios de prótese. Este

5. Avaliação da deformação média gerada nos intermediários e na região peri-implantar durante as etapas de confecção da prótese parcial fixa parafusada: análise com strain gauges / Evaluation of abutment and simulated bone tissue mean deformation around dental implants, during fabrication stages of screw-retained fixed partial prostheses: strain gauges analysis
A adaptação passiva e estabilidade têm se tornado os dois pré-requisitos de maior importância na escolha dos materiais e técnicas de confecção em prótese implantossuportada. A proposta deste trabalho foi avaliar, com auxílio dos strain gauges ou extensômetros lineares elétricos, a deformação média ocorrida nos intermediários e na região peri

6. Evaluation of abutment and perimplantar region deformation of implant-supported screwed prostheses: an study using strain gauges / Avaliação da deformação do intermediário e região perimplantar de próteses implanto-suportada unitárias parafusada: estudo através da extensometria
The dental implant depends on the supporting bone for its stability and functional longevity. Mechanical behavior and trabecular bone structure affect the interface with the implant. Such knowledge may provide a basis for improvements in the current implant function and design, decreasing bone crest resorption and failure at bone-implant junction. Adequate q

7. Analise fotoelastica e extensometrica das tensoes induzidas por estruturas de protese sobre implantes fabricadas pelas tecnicas monobloco, soldagem de borda e metodo CAD/CAM / Photoelastic and strain gauge analysis of tensions induced over implant superstructures manufactured through one-pierce technique., bolder soldering and CAD/CAM method, border soldering and one-piece technique
The lack of passivity of the implant supported prosthesis may lead to mechanical and biological disorders over the implants. By the photoelastic and strain gauge analysis, the purpose of this research was to evaluate the stress over the implants after tightening the prosthesis superstructure over five dental implants. A stainless steel matrix was manufacture

8. Determinação de níveis ótimos de passividade em prótese sobre implante em função da deformação dos intermediários / Optimum passivity levels of implant prosthesis according to abutment deformation
Passive fit has been considered one of the most important requirements for the success of implant supported prostheses. This in vitro study investigated the abutment deformation of an implant-supported prosthesis after screw tightening of palladium-silver and cobalt-chromium prosthetic cylinder. A master model was used to simulate a human mandible with five

9. Photoelastic analysis of stress transmitted from implant-supported frameworks achieved by cilinders lutingand laser welding techniques before and after eletric discharge machining / Analise fotoelastica das tensões induzidas por infra-estruturas implanto-suportadas obtidas pelas tecnicas de cimentação dos cilindros e soldagem a laser, antes e apos eletroerosão
The purpose of the study was to evaluate the passive fit of fixed implantsupported prothesis titanium frameworks, through photoelastic stress analysis. Two frameworks welded in commercially pure titanium (Tritan® -Dentaurum -Germany) were fabricated by two methods based on a metal model composed of five analogous Micro-Unit (Conexão -São Paulo): Framework

The demand for a passive fit of frameworks for osseointegrated endousseous implants abutments is well known, because the tightening of an inaccurate framework to the abutments can transmit stress to the bone-metal interface. The purpose of the present study was to evaluate the influence of the veneering application and porcelain firing cycle on the misfit le

12. A study of the correlation between marginal fit and tensions transmitted to implants by one-piece metal castings - a photoelastic analysis. / Estudo da correlação entre adaptação marginal e tensões transmitidas aos implantes por estruturas metálicas fundidas em monobloco - análise fotoelástica.
Obtaining a good marginal fit of the prosthetic components is one of the main obstacles to the success of rehabilitation with implant-supported prostheses. It is not clear, in the literature, which misfit levels are considered clinically acceptable, but it is known that the absence of a perfect and passive fit may cause inadequate tensions on the osseointegr
