1. Estrutura e riqueza de hepáticas (Marchantiophyta) epifíticas em áreas fragmentadas de Cerrado com borda natural e antrópica / Estrutura e riqueza de hepáticas (Marchantiophyta) epifíticas em áreas fragmentadas de Cerrado com borda natural e antrópica / Structure and richness of the epiphytic liverworts (Marchantiophyta) in fragmented areas of Cerrado with natural edge and anthropogenic / Structure and richness of the epiphytic liverworts (Marchantiophyta) in fragmented areas of Cerrado with natural edge and anthropogenic
The damage caused by the proliferation of edge in forest cover, referred to as edge effects are extensive, may occur over large spatial scales influencing species composition, structure and ecological processes in boundaries of ecosystems. However, studies have shown highly variable response patterns of the taxonomic group studied in relation to the landscap

2. Efeitos de borda sobre comunidades de musgos (Bryophyta) epifíticos em área de Cerrado no Brasil Central / Edge effects on epiphytic mosses (Bryophyta) community in brasilian Cerrado
As mudanças microclimáticas promovidas pela proliferação de bordas nas paisagens fragmentadas, designadas efeitos de borda, podem resultar em alterações na composição de espécies, estrutura das comunidades e processos ecológicos. Apesar do drástico aumento das áreas de borda causadas pela fragmentação antrópica, as bordas e suas áreas de infl

3. Integração de dados ambientais e da avaliação ecológica rápida para o zoneamento da reserva natural Serra do Tombador (Goiás) e diagnóstico do seu entorno
The Private Reserves of the Natural Heritage (Reservas Particulares do Patrimônio Natural) (RPPN) belongs to the Brazilian System of Conservation Units, and they have a cornerstone role for nature conservation given that they allows private land owners, on their own initiative, to contribute in the establishment of new protected areas on their lands. The RP

5. RELATION BETWEEN WEATHER TYPES, EXTREME PRECIPITATION EVENTS AND FLOODS IN THE URBAN SPACE OF SÃO SEPÉ RS / RELAÇÃO ENTRE TIPOS DE TEMPO, EVENTOS DE PRECIPITAÇÃO EXTREMA E INUNDAÇÕES NO ESPAÇO URBANO DE SÃO SEPÉ-RS
Among natural elements the climate assumes importance in that it relates to the ambient question of the cities. The choice for the channel of the Meteoric Impact, among the subsystems of Sistema Clima Urbano (SCU System Urban Climate), justified for the constant episodes of floods in the urban area of São Sepé. In this context, the work has as objective to

6. Florística and fitossociological structure of ciliar bush in the basin of the river Goiana-PE. / Florística e estrutura fitossociológica de mata ciliar na Bacia do Rio Goiana PE.
The importance of the preservation or restoration of the forests to the long one of the rivers, as also, around of lakes, springs and reservoirs is based on the ample specter of benefits that this type of vegetation brings to the ecosystem, exerting protective function on the bióticos and abióticos natural resources. In this context, the study it was carri

7. Efeitos de tensão em filmes finos de manganitas estudados por espectroscopia de absorção de raios-X com luz linearmente polarizada
Among the materials exhibiting the Colossal Magnetoresistance e effect, mixed manganite thin films have received special attention due to their potential applications for new generation magneto-eletronic devices. In these systems, the external biaxial strain could be used to tune the magnetism and transport properties if it were possible to settle the exact

9. Estudo da fauna de artropodes associada a plantas invasoras em agroecossistemas organicos e convencionais
The model of agriculture knoWIl as conventional management, that relies on monocultures and intensive use of sinthetic chemical inputs, brings several damages to human health, natural resources and biodiversity. In the last decades, many altemative agricultural managements have been developed as answers to the chalenge of food production with time and space

10. Mechanisms of cardiac cell excitation with premature monophasic and biphasic field stimuli: a model study.
The mechanisms by which extracellular electric field stimuli induce the (re)excitation of cardiac cells in various stages of refractoriness are still not well understood. We modeled the interactions between an isolated cardiac cell and imposed extracellular electric fields to determine the mechanisms by which relatively low-strength uniform monophasic and bi

11. Selective adherence as a determinant of the host tropisms of certain indigenous and pathogenic bacteria.
The relationship between the selective abilities of bacteria to adhere and their predilections for colonizing different mammalian hosts was investigated by using bacteria indigenous to the tongue dorsum of humans and rats as models. Streptococcus salivarius and S. sanguis averaged 22.6 and 2.8%, respectively, of the cultivable bacteria recovered from swab sa
