13. Dinamica populacional do sistema imune aplicada ao sararmpo / Population dynamics of the immune system applied to measles
This work is a study of the interaction between the measles virus and the human immune system from the point of view of the population dynamics. Dynamical systems of first order non linear ordinary differential equations are used to model this population dynamics. Because of the fact that it is possible to observe two different and quite distinct moments in

14. Ressonadores de microdiscos com região ativa nanoestruturada bombeados por injeção eletrônica / Microdisk resonators with nanostructured active region pumped by electronic injection
This doctorate¿s thesis presents the growth of InAs quantum dots directly on high bandgap InGaAsP (?g=1420 nm) barriers to be used as the active region of microdisk resonators with emission in the C-band (1520¿1570 nm). Based on photoluminescence and atomic force microscopy experiments, the occurrence of inter-diffusion on the InAs/InGaAsP interface is cal

15. Simultaneous measurements of the solid particles velocity and concentration profiles in two phase flow by pulsed ultrasonic doppler velocimetry
In this experimental study, the pulsed ultrasonic Doppler velocimetry was used to measure simultaneously the local velocity and the local concentration in a flow of solid-liquid suspension in a horizontal pipe. In order to distinguish between the Doppler signals coming from the continuous phase, water and those of the glass bead particles larger than the Kol

17. Estudo de anisotropias de UHECR s em dados do Observatorio Pierre Auger / Study of anisotropies of cosmic rays in data from the Pierre Auger
Almost a century after the discovery of cosmic radiation, their origin, composition, acceleration and propagation mechanisms in the universe is still unknown for the ultra-high energy component ( >~ 1018 eV). The mystery grows due to the suppression (GZK cutoff) in the ux of cosmic rays with energies E >~ 6 × 10 19 eV, caused by the interaction of these par

18. Levobupivacaine, ropivacaine and lidocaine on the anesthesia eyelid in the horse: evaluation of intraocular pressure, tear production and the effectiveness of anesthesia / Levobupivacaína, ropivacaína ou lidocaína na anestesia palpebral em equinos: avaliação da pressão intra-ocular, da produção lacrimal e da eficácia do bloqueio anestésico
Corneal anesthesia is required in order to evaluate the intraocular pressure (IOP) and eyelid blockades may also be necessary, using local anesthetic agents in horses. The aim of this study was to evaluate the IOP and the corneal touch threshold (CTT) at the central area of the cornea, after eyelid blockades with anesthetic 0.75% ropivacaine, 0.75% levobupiv

20. Um modelo multiescalas de autômatos celulares para pandemia da dengue / A multiscale cellular automata model for the pandemic of Dengue
The dramatic resurgence and emergence of epidemic dengue and dengue hemorragic fever in the last two decades neatly define a global pandemic. The dispersion of dengue viruses combines local infections of humans bited by infective mosquitoes inside a city with long-range transmissions to non-infective vectors that feed the blood of infected people arriving fr

21. Mapeamento de áreas potenciais a implantação de aterro sanitário em Guarapuava-PR, com uso de redes neurais artificiais
The large production of solid waste and its wrong final destination in the environment have become a problem, especially in urban centers. For what effective measures can be taken, it is necessary to know the local reality, thus to be able act directly in the base of this question. The current system of managing solid residues in the municipality of Guarapua

24. Investigation of adenosine endogenous increase decurrent of D-Frutose-1,6-difosfato administration, a glycolytic intermediate. / Investigação do aumento endógeno de adenosina decorrente da administração do intermediário glicolítico D-Frutose-1,6-difosfato
D-Fructose-1,6-bisphosphate (F1,6BP), a high-energy glycolytic pathway intermediate, is reported to have a many pharmacologically effect, but its underlying mechanism of action in inflammation is incompletely understood. In this study, the aim was to examine the function of F1,6BP on cytokines and adenosine. Then, the possible F1,6BP anti-inflammatory activi
