13. Efeitos do corte seletivo com impacto reduzido na assembléia de borboletas frugívoras da planície amazônica / The effects of reduce-impact logging on fruit-feeding butterflies in Central Amazon, Brazil
A Amazônia representa mais da metade da área de todas as florestas tropicais do mundo, e vem sendo ameaçada por diversas atividades antrópicas, incluindo vários tipos de extração de madeira. O corte seletivo de impacto reduzido (em inglês "Reduced Impact Logging - RIL") é considerado um método menos destrutivo de exploração madeireira que promove

14. Magnetic effect on free convection in a non-darcy porous medium saturated with doubly stratified power-law fluid
Natural convection heat and mass transfer along a vertical plate embedded in a doubly stratified power-law fluid saturated non-Darcy porous medium with uniform heat and mass flux is presented. The governing partial differential equations are transformed into ordinary differential equations using similarity transformations and then solved numerically. The eff

15. Comunidade de morcegos, interações com flores e estratificação vertical em Mata Atlântica do Sul do Brasil / Bat assemblage, interactions with flowers and vertical stratification in the Atlantic Forest, Southern Brazil
Morcegos formam um grupo diverso, abundante e de grande importância ecológica devido às suas interações com outros organismos e com o ambiente. As interações de morcegos com flores podem resultar em polinização, que, embora rara quando comparada às realizadas por outros grupos animais, tem grande importância na reprodução de várias espécies de

16. Influência das frentes frias nos mecanismos de funcionamento da represa da UHE Carlos Botelho (Lobo/Broa) Itirapina SP, dos pontos de vista químico, físico e biológico
In Brazil there is a numerical predominance of river systems, which favors the construction of reservoirs. These reservoirs have great ecological, economic and social significance, so, the management, conservation and recovery of these systems are of fundamental importance with repercussions on the economy, social work and the uses of aquatic systems. Climat

17. Padrões florísticos e estruturais das Florestas Estacionais Semideciduais do Triângulo Mineiro, MG / Floristic and structural patterns of semideciduous seasonal forests of Triângulo Mineiro, MG
The semideciduous seasonal forests (SSF) of southeastern Brazil have a high floristic diversity, accompanied by a high beta diversity, even between nearby fragments. However, nowdays these forests have been represented by a large number of small fragments, a landscape pattern typical for this region. In addition to the processes related to fragmentation, the

18. Estudo da interação de paredes de alvenaria estrutural com a estrutura de fundação
This dissertation presents a study of factors that influence the soil-structure interaction mechanism in buildings and their implications on the behavior of them. Firstly, an extensive bibliographical review was made, and this study broached the main concepts of the SSI research field, such as constitutive models of soil, discrete models to represent soil, s

19. Ecology of Haemagogus sp. and Sabethes sp. (Diptera: Culicidae) in relation to the microclimates of the Caxiuanã National Forest, Pará, Brazil
This study was conducted in a meteorological tower located in the Caxiuanã Forest (municipality of Melgaço, Pará, Brazil) with the aim of assessing the vertical stratification of species of Haemagogus and Sabethes, potential vectors of the yellow fever virus. To investigate the role of microclimates in mosquito stratification, bimonthly collections were c

20. USE OF VERTICAL STRATUM OF SMALL MAMMALS IN GALLERY FOREST AND CERRADÃO SOUTH-WESTERN OF THE BRAZIL / USO DE ESTRATO VERTICAL POR PEQUENOS MAMÍFEROS EM FLORESTA DE GALERIA E CERRADÃO NO SUDOESTE DO BRASIL
Studies on vertical stratification of small mammals in the Cerrado biome are scarce and, therefore, this study has the aim to check the community composition of small mammals in relation to the vertical stratum utilization in gallery forest and cerradão of south-western Brazil. The captures were carried out during the months of August/September, November/De

21. DistribuiÃÃo espacial e efeito de borda em briÃfitas epÃfitas e epifilas em um remanescente de floresta atlÃntica nordestina
Bryophytes work like a key group to elucidate answers to the environmental variations because his elevated sensibility to microclimate and especific microhabitats. This study aimed to deepen the knowledge on the ecology of epiphyte and epiphyllous bryophyte communities in relation to fragmentation in an Atlantic Forest remanant (2.628ha) of the Ecological St

22. NUMERICAL MODELING OF SEWAGE PLUME DISPERSION FOR THE SANTOS OUTFALL / Modelagem numérica da dispersão da pluma do emissário submarino de Santos
Sewage plume dispersion for the Santos outfall was studied using numerical models, coupling hydrodynamic, near field and far field models. Experiments were conducted for the 1979 original outfall design, for the new 2009 outfall configuration and also for a third arrangement suggested here, which duplicates the emissary length comparatively to the original 1

23. Estrutura, estratificação e grupos ecológicos de um fragmento de floresta estacional semidecidual (Uberaba, MG)
Seasonal semideciduous forests (FES) occur in patches mainly in the region of the Cerrado of central Brazil, had occupied a expressive area throughout Minas Gerais state. These formations generally occur on fertile and humid soil, characterized for the climatic changes that determines the seasonal deciduousness of the dominant tree individuals, in reply the

24. Processos dinÃmicos e evolutivos da zona costeira de Itamaracà por sensoriamento remoto e medidas in situ
The coastal zone of Itamaracà is like a highly dynamic environment where land and oceanic processes interact altering frequently coastal characteristics. In this context, this current study examines the responsible processes of such changes from the development and application of methodologies, which includes digital image processing and the obtaining of in
