13. Immediate response of myocardium to pressure overload includes transient regulation of genes associated with mitochondrial bioenergetics and calcium availability
Ventricular hypertrophy is one of the major myocardial responses to pressure overload (PO). Most studies on early myocardial response focus on the days or even weeks after induction of hypertrophic stimuli. Since mechanotransduction pathways are immediately activated in hearts undergoing increased work load, it is reasonable to infer that the myocardial gene

14. ANÃLISE DE SISTEMAS DE IMPLANTES DENTÃRIOS EM MANDÃBULAS EDÃNTULAS COM APLICAÃÃO DE CARREGAMENTO IMEDIATO / Study of the systems of dental implantations for edentulous mandibula with immediate load
The present study aimed at obtaining comparative elements among the guided systems of fixed complete denture with 4 osseointegrated implants with immediate loading, considering the importance of understanding the implant project as a process where biomaterials and biomechanics are assessed. The three-dimensional finite element method was used to analyze the

15. Analise histologica e histomorfometrica do reparo osseo perimplantar em cães submetidos a instalação de implantes endosseos com um modelo de carga precoce em dois diferentes desenhos de implantes / Histological and histomorphometric analysis of perimplant osseous repair in dogs submitted to endosseous implant installation with early load model in two different implant design
Several treatment types using prosthesis over implants have been reported, being the singles immediate loading therapy with more controversy. The meaning of the present study is established the characteristics of bone repair in dental implant submitted to immediate loading. It was performed a experimental model using dogs to value two different installations

16. Carga imediata sobre implantes osseointegráveis para ancoragem ortodôntica: estudo em minipigs / Immediately loaded osseointegrated implants for orthodontic anchorage: study in minipigs
O objetivo deste trabalho foi avaliar a taxa de sucesso, a quantidade de perda óssea em altura e a interação osso/implante para três diferentes protocolos: 1) implantes osseointegráveis mantidos sem carga durante período de reparo de 120 dias; 2) implantes submetidos a interferências oclusais; e 3) implantes que receberam carga imediata para ancoragem

17. Clinical and mechanical performance of self-etching adhesive to primary caries-affected dentin / Desempenho clinico e mecanico de adesivo auto-condicionante a dentina decidua afetada por carie
The purpose of this study was to verify the effect of flask closure method (conventional clamp and RS tension system) and post-pressing time (immediate and after 6 hours) on the maxillary denture base adaptation made with Classico and QC-20 heat?cured acrylic resins. Eighty maxillary stone cast/wax base sets were made and randomly assigned into 8 groups (n=1

18. Exigency-based real-time scheduling policy to provide absolute QoS for web services / Política de escalonamento de tempo real baseada em exigência para provisão de QoS absoluto em serviços Web
The present work presents a study, implementation and validation in a simulated environment of a real time scheduling policy to provide absolute QoS for web services. Synthesizing characteristic from real time scheduling, low latency and feedback scheduling, the proposed policy allows an adjustment weighed by the quantification of the exigency which the syst

19. VOLTAGE CONTROL SENSITIVITY CALCULATION FOR VOLTAGE STABILITY OPERATIONAL REINFORCEMENT / ADEQUAÇÃO DAS AÇÕES DE CONTROLE DE TENSÃO EM SISTEMAS ELÉTRICOS OBJETIVANDO O REFORÇO DAS CONDIÇÕES DE SEGURANÇA DE TENSÃO
The voltage stability problem has been associated with environment questions and lack of financial resources for transmission system expansion. This reality together with the load growth makes the electrical system to be subject of heavy loadings, what can lead to situations of voltage collapse. The development of methods for evaluation of transmission netwo

20. Análise biomecânica de implantes odontológicos / Biomechanical Analysis of Dental Implants
Objetivou-se nesta dissertação analisar a distribuição das tensões e deslocamentos na interface osso-implante, utilizando o método dos elementos finitos. Os implantes foram analisados em duas situações distintas: assentados diretamente nas duas camadas ósseas, cortical e trabecular, simulando a situação de carga imediata, anterior a osseointegraç

22. Immediate and time-dependant behavior of RC columns strengthened by high-performance concrete jackets / Comportamento resistente imediato e ao longo do tempo de pilares reforçados por meio de encamisamento com concreto de alto desempenho
The thesis presents an experimental investigation on the behavior of RC columns strengthened by high-performance concrete jackets. The main objectives are to analyze the immediate and time-dependant behavior of the elements and the preloading effect in its load capacity and deformability. Twenty columns were tested varying the transversal section shape (circ

23. Regulação da expressão e ativação do fator de transcrição C-JUN no miocardio de ratos submetido a sobrecarga pressora aguda
The early expression of immediate early genes is a fundamental feature of myocardial hypertrophy. The immediate early gene c-jun codifies a transcription factor that has been assigned to be an important regulator of the hypertrophic response in cardiac myocytes. In the present study we investigated whether pressure overload or phenylephrine treatment stimula

24. Influencia do tempo pos-prensagem (imediato e 24 horas) na porosidade, rugosidade, dureza de superficie e resistencia ao impacto de resinas acrilicas
This study investigated the influence of the post-pressing time (immediate and 24 hours) on the porosity, roughness, hardness of surface and impact strenght variables in Clássico, QC-20 and Onda-Cryl thermo-cured acrylic resins. Sixty specimens were made with a retangular aluminium die (65xl0 and 64x9 x 3,0 mm) attached to a wooden plate with Super Bonder a
