13. Subtipos de receptores colinérgicos centrais envolvidos na salivação, ingestão de água e resposta pressora induzidas pela pilocarpina injetada perifericamente / Subtipos de receptores colinérgicos centrais envolvidos na salivação, ingestão de água e resposta pressora induzidas pela pilocarpina injetada perifericamente
O estudo de substâncias sialagogas tem interesse clínico pela utilidade que elas têm em pacientes com reduzida secreção salivar. Entre essas substâncias destacam-se os agonistas colinérgicos e entre esses, um dos mais importantes é a pilocarpina. Embora uma ação direta da pilocarpina em receptores colinérgicos muscarínicos das glândulas salivare

14. The effect of vibration on bed voidage behaviors in fluidized beds with large particles
The effects of vibration parameters, operating conditions and material properties on bed voidage were investigated using an optical fiber probe approach in a vibrating fluidized bed with a diameter of 148 mm. Variables studied included frequency (0-282 s-1), amplitude (0 mm-1 mm), bed height (0.1 m-0.4 m) as well as four kinds of particles (belonging to Geld

15. Robust control of FACTS devices to damp oscillations in electric power systems / Controle robusto de dispositivos FACTS para o amortecimento de oscilações em sistemas elétricos de potência
Este trabalho apresenta um método sistemático para projeto de controladores suplementares para um tipo de dispositivo FACTS (o modelo TCSC) para o amortecimento de oscilações em sistemas elétricos de potência. Adota-se uma metodologia previamente desenvolvida para projeto de apenas controladores de tipo PSS. Tal metodologia é fundamentada na teoria de

16. "Propriedades estruturais de agregados anfifílicos catiônicos: interação com material genético" / structural properties of cationic amphiphilic aggregates: interaction with genetic material
Though less efficient than viral vectors, cationic lipids have been used as carriers in gene therapy. They offer several advantages over viral vectors, including the low immunogenic and inflammatory responses, the potential transfer of unlimited-size expression units, and the possibility for engineered cell-specific targeting. However, the interaction betwee

17. Assessment of different revolving time combinations on coffee grains drying using a fixed-bed dryer / AvaliaÃÃo de diferentes combinaÃÃes de tempo de revolvimento, em secador de camada fixa para cafÃ
This assignment aimed to value the energetic efficiency on coffee drying (Coffea Arabica, L.), with different combinations of time revolvment on a fix layer dryer. The experiment was developed on July, 2004 in Jesuitas city, ParanÃ. The dryer was compound of: a drying chamber with a capacity to 4,5 m3 of grains, chamber plenum with volum of 2,9 m3, fan with

18. Stability of Semidiscrete Formulations For Advective-Diffusive-Reactive Transport Problems / Estabilidade temporal de formulações semi-discretas para problemas de transporte convectivo-difusivo-reativo
This work deals with the stability analysis of the fully discrete transport problem obtained using a stable finite element method in space and the generalized trapeizoidal family of methods in time. Depeding on the range of parameters the Galerkin and the Streamline Upwind Petrov-Galerkin Methods are introduced. We evaluate the accuracy and stability propert

19. Biomechanics load transmission single implants according to prosthetic materials photoelastic and dinamic analysis / "Biomecânica da transmissão de cargas a implantes unitários em função dos materiais protéticos: análise fotoelástica e dinâmica"
Less rigid oclusal materials such as acrylic resins are often used in prosthesis over implants because they are supposed to diminish the loads transferred to the bone; however there is no scientific evidence to support this theory. The objective of this work was to compare by photoelastic and dynamic analysis the load transfer after oclusal loads over single

20. Distribuição geografica, forofitos e especies de bromelias epifitas nas matas e plantações de cacau da região de Una, Bahia
The loss of species is a natural outcome when habitats are fragmented or changed. Nevertheless, epiphytes would be particularly susceptible to this process given the high number of species with limited geographical distribution. In modified habitats changes are ais o expected in the species composition and differences in the overall abundance in the organism

21. Integrated structural/control optimization of a large space structure with articulation subject to the gravity-gradient torque.
Optimization has been playing a very important role in the orbit and attitude control, and structural design of spacecraft since the advent of the space era. It is well known that weight, space, energy, and time are among the most important constraints that guide the space missions planning. the optimization has a wide field of applications even if only the

22. Mecanismos ionicos envolvidos na regulação da secreção de insulina por agonistas muscarinicos
O presente trabalho teve como proposta caracterizar o subtipo funcional de mAChR na célula ? pancreática, bem como elucidar os mecanismos iônicos envolvidos na estimulação muscarínica. Para isto, foram utilizadas ilhotas de ratos e camundongos, isoladas por digestão enzimática ou microdissecção. A resposta celular frente a estimulação pelo agonis

23. Misincorporation of dAMP opposite 2-hydroxyadenine, an oxidative form of adenine.
Nucleotide incorporation opposite an oxidative form of adenine, 2-hydroxyadenine (2-OH-Ade) was investigated. When a primed template with 2-OH-Ade was treated with an exonuclease-deficient Klenow fragment of Escherichia coli DNA polymerase I (KFexo-), recombinant rat DNA polymerase beta (pol beta) or calf thymus DNA polymerase alpha (pol alpha), incorporatio

24. A comparison of the fidelity of copying 5-methylcytosine and cytosine at a defined DNA template site.
5-Methylcytosine has been postulated to be an endogenous mutagen in procaryotes and eucaryotes leading to base substitution hot spots, C-->T transitions, resulting from spontaneous deamination of mC to T. The possibility remains, however, that a second mechanism involving mispairing of mC with A might also contribute to base substitution mutagenesis via G-->
