13. Avaliação eletrofisiológica in vitro de drogas antiepilépticas em fatias hipocampais humanas provenientes de pacientes portadores de epilepsia do lobo temporal refratária ao tratamento medicamentoso
The absence of a satisfactory response to antiepileptic drug (AED) therapy, is an unresolved problem in a significant number of epileptic patients. Mechanisms of intractability are not well understood but may include a combination of poor penetration of AED across a functionally altered blood-brain barrier owing to increased expression of multiple drug resis

14. Estudo do aspecto odonto-legal das lesões corporais decorrentes de violencia domestica / Dental forensic identification of body lesions caused by domestic violence
Domestic violence is a problem among families worldwide. Victims usually present at medicolegal services with complaints about several kinds of aggression. In most cases, these medicolegal services, just like the one in Vitória, Espírito Santo, Brazil, lack forensic dentists. The aim of this work was to assess lesions located at the stomatognathic apparatu

16. Strategies to alleviate the incidence of ascites in broilers: a review
Ascites is a complex problem caused by many interacting factors such as genetics, environment and management. Many nutritional, medicinal and management strategies have been proposed to alleviate the problem. Higher levels of dietary vitamin C and E along with selenium yeast might be beneficial, presumably because of their role in improving cellular integrit

17. MÃtodos variacionais e soluÃÃes periÃdicas minimizantes para os problemas de Kepler, 3 e 4 corpos
In this dissertation, we make an introduction to the variational methods with intention of finding minimum of certain functionals. In particular, the minimum of the action function, are solutions of the N-body problem if they donât collisions. We study the minimum of the action functional for the Kepler problem, where we have check that on certain spaces th

18. The effect of polar and many-body interactions on the optical properties of III-nitrides / Estudo dos efeitos polares e de muitos corpos nas propriedades opticas de III-nitretos
Neste trabalho realizamos um estudo pormenorizado das propriedades ópticas de semicondutores polares de gap direto dopado tipo n.Em particular nos concentramos nos efeitos de muitos corpos (interação coulombiana)e na in .uência da interação elétron fônon LO (potencial de Fröhlich)sobre as propriedades ópticas do sistema. Para tanto,inicialmente,cal

19. Intrabuccal submucosal infiltration with betamethasone for the prevention or control of pain in endodontics / Infiltração submucosa intrabucal de betametasona na previsão ou controle da dor em endodontia
Posttreatment endodontic pain is still a significant problem in dentistry. The aim of this randomized double-blind study was to evaluate, in two stages, the effect of betamethasone on the control of postoperative pain in patients submitted to endodontic treatment. In the first stage, patients were asymptomatic, whereas in the second, pain was already present

20. Tropical House Gecko (Hemidactylus mabouia) predation on brown spiders (Loxosceles intermedia)
Brown spiders (Loxosceles spp.) are venomous arachnids, successfully adapted to urban habitats in Brazil. Loxoscelism became a serious public health problem in Paraná State, especially at the capital Curitiba, where the most abundant species is Loxosceles intermedia. Hemidactylus mabouia (Gekkonidae) lizards are synanthropic predators of arthropods. In this

21. Psychological boarding of the Problem of Pertaining to school Learning: What in the child teaches to them who does not learn? / Abordagem psicolÃgica do problema de aprendizagem escolar : o que nos ensina a crianÃa que nÃo aprende?
This work had for objective to investigate the school learning problems pertaining to children of second year of Basic School, from the Psychology look, and its connection between cognition and affectivity. Although the school failures have multiples causes, we made a cut out for situations where it assumes the symptom form, denouncing, in the language of ou

22. O papel da interação elétron-elétron no regime Hall quântico interio.
Experimental and theoretical studies of the aspects of particle-like and collective behavior of electrons in the proximity of the edges of two-dimensional (2DES) and quasi-one-dimensional (Q1DES) systems, named quantum wires (QWs), in semiconductor heterostructures reveal the important role of the electron-electron interaction on the edge states in the integ

24. Origem e Evolução Dinâmica de Algumas Populações de Pequenos Corpos Ressonantes no Sistema Solar / Dynamical evolution and origin of some populations of small Solar System resonant bodies
Nesta tese estudamos algumas regiões de aparente estabilidade no cinturão de asteróides e no cinturão de Kuiper, analisando a evoluçãao dinâmica dos objetos nessas regiões por intervalos de tempo muito longos, em geral, da ordem da idade do Sistema Solar. Centramos principalmente nossa atenção no estudo das populações de pequenos corpos ressonant
