13. The spatial distribution of the subtidal benthic macrofauna and its relationship with environmental factors using geostatistical tools: a case study in Trapandé Bay, southern Brazil
Modeling the distribution patterns of the estuarine macrobenthic community has revealed itself as a difficult task due to spatio-temporal heterogeneity. This study uses ordinary kriging and Poisson modeling to generate distribution maps of the subtidal benthic macrofauna in the Trapandé Bay (southeastern Brazil). Samples were taken in duplicate from 36 loca

14. Avaliação de parâmetros bioquímicos e comportamentais em peixe-zebra (Danio rerio) : uma abordagem sobre o sistema purinérgico, colinérgico e efeitos promovidos pela taurina no modelo de exposição aguda ao etanol
The zebrafish (Danio rerio) is a small teleost fish that belongs to the Cyprinidae family, which has been studied in different scientific areas. This species has evolutively conserved genes, several neurotransmitter systems characterized, and a wide behavioral repertoire, which may be modulated by distinct drugs. Thus, this thesis aims to study biochemical p

15. Influência da orientação corporal e do treino específico nos parâmetros espaço-temporais na emergência do alcance em lactentes / Influence of body orientation and specific training on spatio-temporal parameters on emergency of reaching in infants
Considerando que as mudanças no processo de adaptabilidade do organismo ocorrem em resposta à influência convergente de restrições intrínsecas e extrínsecas, estudos têm demonstrado que a orientação corporal e a prática podem influenciar positivamente os movimentos dos membros superiores em lactentes. Sendo assim, o presente estudo apresenta dois

16. Variação espaço-temporal da ictiofauna da zona de arrebentação da Praia do Cassino, Rio Grande do Sul, Brasil
This study analyzes the spatiotemporal variation of the ichthyofauna of the surf zone of Praia do Cassino, municipality of Rio Grande (state of Rio Grande do Sul, Brazil) from October 2005 to September 2006. Fishes were collected monthly and during daytime using a large beach seine net (30 m x 1.8 m, with 12 mm uniform mesh manufactured with monofilament nyl

17. Simulation, analysis and computational characterization of fingering patterns in fluids displacement on porous media. / Simulação, análise e caracterização computacional de padrões de fingering em deslocamentos de fluidos em meios porosos
In this work, the patterns related to the displacement process of an interface between two ftuids of different mobilities are studied computationally. In the literature, the formation process of these patterns is known as fingering, a type of dynamic instability in the interface between two miscible fluids, where the fingers are classified in two types: dens

18. Locomoção infantil: variáveis espaço-temporais no andar em diferentes velocidades / Locomoção infantil: variáveis espaço-temporais no andar em diferentes velocidades
The literature suggests that there are large changes in gait patterns with progression speed. This study aimed to examine the differences in variables spatiotemporal during the walking at three different speeds (slow, self-selected and fast) among three age groups of children. Healthy children (n=33) were distributed in the following groups: 3-4 years, 5-6 y

19. Gait analysis in myotonic dystrophy type 1 : spatiotemporal and kinematics parameters / Estudo da marcha da distrofia miotonica tipo 1 : parametros espaciais, temporais e cinematica
Myotonic Dystrophy type 1 is a multisystemic disease that frequently affects the striated muscle with repercussion on gait. Gait function may be very abnormal or exhibit subtle alterations of difficult characterization by the human eyes. With objective to analyse the spatiotemporal and kinematics variables parameters of gait in patients affected by the disea

20. Sincronizacão em Rede Sem Escala
We considered a coupled chaotic logistic map lattice exhibiting the scale free property: the outreach connectivity of each node obeys a power-law distribution. We analyzed a weak form of coherent spatio-temporal behavior, the direction coherent, wich presents features common to completely synchronized states, like a transitional behavior mediated through int

21. The influence of intrinsic and extrinsic constraints on reaching movements in young infants. / Influência de restrições intrínsecas e extrínsecas no alcance manual de lactentes.
The aim of the current research was to examine the influence of intrinsic and extrinsic constraints on reaching movements in 4-6-month-old infants. Age, level of skill and experience gained by spontaneous practice of reaching were the intrinsic constraints analyzed. The relationship between muscular torque required for reaching and gravitational torque was t

22. Análise de conteúdo de vídeo por meio de aprendizado ativo
Advances in compression techniques, decreasing cost of storage, and high-speed transmission have facilitated the way videos are created, stored and distributed. As a consequence, videos are now being used in many applications areas. The increase in the amount of video data deployed and used in today s applications reveals not only the importance as multimedi

23. Spatio-temporal hierarchical modelling of the coffee berry borer (Hypothenemus hampei Ferrari) dispersion in colombia. / Modelagem da distribuição espaço-temporal da broca do café (Hypothenemus hampaei Ferrari) em uma cultura da região central colombiana.
Study of agricultural pests distribution in space and time provides important information about the species dispersion mechanisms and its interaction with environmental factors. It also helps the development of sampling plans, the integrated pest management and planning of experiments. The aim of this work was to compare several hierarchical models in modell

24. Spatio-temporal dynamics and transition from asymptotic equilibrium to bounded oscillations in Chrysomya albiceps (Diptera, Calliphoridae)
The sensitivity of parameters that govern the stability of population size in Chrysomya albiceps and describe its spatial dynamics was evaluated in this study. The dynamics was modeled using a density-dependent model of population growth. Our simulations show that variation in fecundity and mainly in survival has marked effect on the dynamics and indicates t
