Seed germination of a rare neotropical canopy tree dormancy and the effects of ...
Ramos,Flavio Nunes; Andrade,Antonio Carlos Silva deThe purpose of this study was to examine if germination is a critical phase on Enterolobium glaziovii regeneration. Hence, the germinative response of E. glaziovii seeds was investigated in relation to some of the main environmental factors (temperature, light and water stress) to which its seeds are subjected in the forest, as well as its dormancy and the longevity of its burial seeds. According to our results...
Tree structure and richness in an Atlantic Forest fragment: distance from anthr...
Ribeiro,Maíra Taquiguthi; Ramos,Flavio Nunes; Santos,Flavio Antonio Maës DosApproximately 7.2% of the Atlantic rainforest remains in Brazil, with only 16% of this forest remaining in the State of Rio de Janeiro, all of it distributed in fragments. This forest fragmentation can produce biotic and abiotic differences between edges and the fragment interior. In this study, we compared the structure and richness of tree communities in three habitats - an anthropogenic edge (AE), a natural ...
Propagação de ondas e detecção de danos com modelos de barra de alta ordem pelo...
Flavio Nunes PereiraEste trabalho investiga o problema de propagação de ondas em estruturas do tipo barra com modelos de alta ordem. O enforque principal do trabalho concentra-se na implementação de modelos numéricos que representem o fenômeno da propagação de ondas em barras saudáveis e danificadas por uma trinca. Para a investigação do problema utilizou-se o Método do Elemento Espectral, o qual consiste em uma solução analítica ...

Sivini,Flávio Nunes; Brandt,Carlos Teixeira; Belo Filho,DjalmaOBJETIVO: avaliar a repercussão da hipertensão porta nos índices de resistência arterial ovariano, uterino e na periferia do corpo lúteo, na fase lútea média do ciclo menstrual. MÉTODOS: em estudo observacional com corte transversal, 28 portadoras de esquistossomose mansônica na forma hepatoesplênica submetidas à esplenectomia e ligadura da veia gástrica esquerda (EHEO), um grupo similar de 28 pacientes não ope...
Maia. Identificação de uma Cidade. BM99, Bienal da Maia
Carlos Maia; Cecília Delgado; Flávio Nunes; Paula Guerra; Pedro GadanhoThe relationship between society and the city, can not reduce the spontaneous emergence of urban forms, but the existence of social actors carrying from perspectives of representations and forms of action within the city of Maia. The diversity and complexity of forms of appropriation by the population, its public and semi-public spaces and institutions and are determined by many different factors, both internal...

FlÃvio Nunes SiviniA fim de avaliar a repercussÃo da hipertensÃo porta nos Ãndices de resistÃncia arterial e na drenagem venosa ovariana e uterina, foram estudadas vinte portadoras de esquistossomose mansÃnica na forma hepatoesplÃnica submetidas à esplenectomia e ligadura da veia gÃstrica esquerda (grupo I) e um grupo similar de pacientes nÃo submetidas à cirurgia (grupo II). Os parÃmetros foram comparados com vinte voluntÃrias s...
Floral biology and breeding system of Psychotria tenuinervis Muell. Arg. (Rubia...
Virillo,Carolina Bernucci; Ramos,Flavio Nunes; Castro,Cibele Cardoso de; Semir,João(Floral biology and breeding system oi Psychotria tenuinervis Muell. Arg. (Rubiaceae) in the Atlantic rain forest, SE Brazil). The aim of this study was to investigate pollination biology, floral morphometry, morph ratio and breeding system oiPsychotria tenuinervis in an area of Atlantic rain forest in southeastern Brazil. Pollination biology was studied based on focal observations and the breeding system was d...
Spatial distribution of seeds and juveniles of Enterolobium glaziovii Bentham (...
Ramos,Flavio Nunes; Matos,Dalva M. Silva; Santos,Flavio A.M.The spatial distribution of fruits and juveniles of Enterolobium glaziovii Bentham were evaluated in four circular plots of 30 m radius, centered around reproductive individuals to determine whether the size of the parental crowns, topography, and canopy coverage influence these patterns. Each crown was subdivided into eight irregular triangles and the area of each was calculated. Each plot was subdivided into ...

Artur Pimenta Alves; Carlos José Rodrigues; Flávio Nunes; Gonçalo Alves Santinho; Jorge Bateira; José Carlos Caldeira; José Manuel MendonçaStructural changes in the processes of socio-economic development, with consequent implications for economic growth, social and territorial cohesion, and the quality of democracy, flow into, currently, a society characterized by the growing importance of cognitive resources, the constant advancement of the information and communication technology (ICT) and the consequent change in the lives of the people and th...
Polinização e qualidade de sementes produzidas por Pychotria tenuinervis (Rubia...
Flavio Nunes RamosSpatial and temporal climatic variability among areas may affect the reproductive events of plant and animal populations. Habitat changes or abrupt limits between habitats can affect the interactions between plants and their pollen and seed vectors and lead to a decrease in seed quality because of increased inbreeding. The isolation of forest patches and the edges created by fragmentation may change the abiotic...
