3. DinÃmica Geoambiental do Sistema HÃdrico MaceiÃ/Papicu / Dynamic Geoenvironmental System Hydride Maceià / Papicu
This research aims to analyse the geo-environmental features of the MaceiÃ/ Papicu Hydrical System relating the dynamic in the natural landscape to the human aspects. The survey is based on the process of degradation from occupation considering the changes and their consequences to the environment. By means of the visual interpretation of the AUMEF 1978 air

4. Dinâmica populacional e efeitos de variáveis ambientais sobre a fauna de pequenos mamíferos em um fragmento de floresta com araucária no sul do Brasil
Natural populations of small rodents fluctuate continually over time and the population dynamics of any living organism are shaped by both intrinsic and extrinsic factors. Small mammals populations can show a continuum dynamic activity, ranging from stability to regular cycles of variable amplitude. The species dynamics is also known to be influenced by the

5. Populational dynamic and immunology study of the case of streptococcus and staphylococcus / Dinamica populacional e imunologia : estudo do caso de estreptococos e estafilococos
Bactérias que vencem a barreira física do organismo normal podem provocar reações inflamatórias localizadas. Essa reação é um dos componentes do sistema imunológico para conter invasão de micro-organismos ao corpo humano. Desenvolve-se um modelo matemático para descrever essa resposta do sistema imunológico, levando em consideração a patogenici

6. Diversidade de ácaros (Acari) e biologia deTetranychus mexicanus (Mcgregor) em Annonaceae / Diversity of mites (Acari) and biology of Tetranychus mexicanus (Mcgregor) on Annonaceae
The family Annonaceae Juss. is composed by more than 120 genera and 2000 species, from the tropical regions of America, Asia and Africa. Many of these species are edible; the genus Annona is the most cultivated. Phytophagous and predators mites are commonly found in Annonaceae, however in Brazil few reports of the mites are associated with this family. This

7. SimulaÃÃo da DinÃmica Populacional do PulgÃo Aphis gossypii Glover e sua interaÃÃo com o parasitÃide Lysiphlebus testaceipes. / Aphis gossyppi Glover, 1877 populational dynamics simulation and its interaction with the parasitoid Lysiphlebus testaceipes (Cresson, 1880)
Recently, Giarola et al. (2006) have simulated the populational dynamics of Aphis gossypii Glover, 1877 in different temperatures and chrysanthemum cultivares (Dendranthema grandiflora Tzvelev), by using the Penna Model (Penna, 1995) and experimental data from Soglia et al. (2002, 2003). Though the results are satisfactory, the post reproductive period, obse

8. DINÂMICA POPULACIONAL DE TRACHEMYS DORBIGNI, (TESTUDINES: EMYDIDAE) EM AMBIENTE ANTRÓPICO EM PELOTAS, RS / POPULATIONAL DYNAMIC OF TRACHEMYS DORBIGNI (TESTUDINES: EMYDIDAE) IN AN ANTHROPIC ENVIRONMENT IN SOUTHERN BRAZIL
Informations about the population dynamic of Trachemys dorbigni were collected from February 2006 to January 2007, in the Santa Barbara stream, Pelotas, Brazil. It was collected 377 individuals in the traps, 160 females, 146 males and 71 juveniles. The sex ratio was not different from 1:1. Males of T. dorbigni reached sexual maturity at 127 mm length. The sm

9. Processos de partÃculas sem colisÃes
We consider a class of particle processes with discrete time and a finite number of types of particles, which we call Processes Without Collisions or PWC for short. At every time step, any particle may die or transform itself into one or several particles of any types with certain probabilities, but there are no collisions, that is, every transformation appl

10. Migração recente nas mesorregiões de Minas Gerais segundo os censos demográficos de 1991 e 2000
The dynamic of space distribution of Minas Gerais population has supplied elements of great importance for discussion over configuration processes on new areas of population attraction. On this matter, the aim of this theses is based upon demographic census from 1991 to 2000 to analyse the recent immigration behavior on meso regions of Minas Gerais complemen

11. Modelagem alternativa para dinamica populacional : sistemas dinamicos fuzzy / Alternative modelling for populational dynamic : fuzzy dynamical systems
Neste trabalho utilizamos a teoria dos conjuntos fuzzy de duas maneiras distintas para a modelagem de dinâmica populacional como alternativa para a modelagem determinística: problema de valor inicial fuzzy e sistemas baseados em regras fuzzy. Apresentamos algumas das principais propriedades da solução de um problema de valor inicial fuzzy obtida por exte
