1. Dynamic changes in and time sequence of ultraviolet B-induced apoptosis in rat corneal epithelial cells
RESUMO Objetivos: Explorar sistematicamente as mudanças dinâmicas e a sequência temporal no processo de apoptose de células epiteliais corneanas após excesso de irradiação com ultravioleta B. Métodos: A radiação ultravioleta B (144 mJ/cm2) foi utilizada para irradiar células epiteliais da córnea de rato durante 2h. A morfologia celular foi obse

3. Processos hidrológicos em uma sub-bacia do Parque Estadual da Serra do Mar, núcleo Santa Virgínia
Resumo O presente estudo busca caracterizar o funcionamento hidrológico de uma sub-bacia com cobertura de Mata Atlântica, localizada no Parque Estadual da Serra do Mar, núcleo Santa Virgínia. Para isso, foram monitorados entre os anos de 2008 e 2009, alguns processos hidrológicos: escoamento superficial, umidade do solo (0,15, 0,30, 0,50 e 0,90 metros d

4. Temporal Behavior of Tree Communities in Different Soil Classes
ABSTRACT The objective of this work was to evaluate if the soil heterogeneity expressed by the different soil classes would condition tree communities with different dynamic behaviors. The data were collected from 25 plots sized 20 × 20 (400 m²), 10 of them with Inceptisols, 9 with Ultisols, 5 with Entisols B and 1 with Entisols A. All individuals with DBH

5. Etiology, occurrence and epidemiology of a begomovirus disease in passionflower in the southwest of Bahia
ABSTRACT: Severe mosaic symptoms, accompanied by yellow spots, abnormally small leaves, fruit malformation and cracking, reduced plant growth, and high levels of whitefly (Bemisia tabaci MEAM1) infestation were observed in passionflower (Passiflora edulis) orchards in southwestern Bahia, Brazil. The aim of this work was to identify the species of begomovirus

6. Urban phenomena in São Paulo’s nineteenth and twentieth centuries: appropriating local spatio-temporalities
Resumo O artigo investiga fenômenos urbanos na São Paulo dos séculos XIX e XX lançando mão do conceito de apropriação de Henri Lefebvre. Assim, enfoco as relações entre espaço(s) urbano(s) e seus habitantes, e a análise da cidade – usualmente percebida como espaço – se torna análise espaçotemporal e relacional de práticas, conflitos etc. d

7. Floral Scent and Nectar Sugar Composition of Temnadenia odorifera (Apocynoideae, Apocynaceae)
Temnadenia odorifera is an endemic species from the Brazilian Atlantic Forest. This study was developed in order to identify the volatile compounds emitted by the living flowers and nectar, to evaluate the temporal pattern of scent emission, and the sugars composition of its nectar. Analyses of the flower scent by dynamic headspace in vivo, of nectar sugar c

8. Temporal Variation of Soil Physical Quality under Conventional and No-Till Systems
ABSTRACT: Determination of soil physical quality (SPQ) is very important because it is related to many important soil processes. However, it is not clear which indicators should be considered in this evaluation, and information about temporal variation of SPQ under different soil tillage systems is scarce. The aim of this study was to determine the effects o

9. Temporal changes in species composition, diversity, and woody vegetation structure of savannas in the Cerrado-Amazon transition zone
ABSTRACT Vegetation in the transition between tropical forest and savanna is hyperdynamic and there is evidence that in the absence of fire, forest advances over savanna. Between 2008 and 2013 we evaluated changes in species composition and diversity and in the structure of the woody vegetation of savanna physiognomies in the transition between the Cerrado a

10. Regions and the Globe: A Spatial-Temporal Framework for Foreign Policy Analysis
Does the regional environment shape a state's international socialization and, thus, its perception on external affairs? If this is the case, how does such a process happen and what are the consequences for a state's global foreign policy? We tackle both questions by elaborating an analytical framework that accounts for spatial-temporal interactions in forei

11. TOPOGRAPHIC ASPECTS IN THE SPATIAL AND TEMPORAL DYNAMIC OF NET RADIATION
ABSTRACT: The measurements obtained by remote sensing are influenced by issues related to relief. Based on that, this paper aims to analyze the spatial and temporal dynamics of the net radiation (Rn), considering the influence of topographic parameters on it, in Edgárdia Experimental Farm (FEE). It was used the methodology based on the SEBAL algorithm (Surf
