1. A SIR Model with Spatially Distributed Multiple Populations Interactions for Disease Dissemination
ABSTRACT In this contribution we analyze a discretized SIR (Susceptible, Infectious, and Removed) compartmental model, to investigate the role of individual interactions in the spread of diseases. The compartments S i,j , I i , j and R i , j ( i , j , = 1 , 2 , . . . , n ) are spatially distributed in a two-dimensional n × n network. We assume tha

2. Um novo ecossistema: florestas urbanas construídas pelo Estado e pelos ativistas
resumo Historicamente, a expansão das cidades resultou na substituição da paisagem natural pela urbana, tendo como consequência a degradação ambiental por meio das mudanças na cobertura do solo, nos sistemas hidrológicos, nos ciclos biogeoquímicos, no clima e na biodiversidade, tornando as cidades especialmente vulneráveis às mudanças climáticas

4. Interplay between Near-Field Properties and Au Nanorod Cluster Structure: Extending Hot Spots for Surface-Enhanced Raman Scattering
Materials science has observed a continuous increase in the use of metal nanoparticles in a wide range of studies, from fundamental physics to technological applications such as photocatalysis and optical communication devices. This broad scope has the same fundamental origin, the localized surface plasmons, whose excitation leads to strong light confinement

5. Genetic Population Structure and Allele Surfing During Range Expansion in Dynamic Habitats
Abstract: Expanding populations may loss genetic diversity because sequential founder events throughout a wave of demographic expansion may cause “allele surfing”, as the alleles of founder individuals may propagate rapidly through space. The spatial components of allele surfing have been studied by geneticists, but have never been investigate on dynamic

6. Shifting habitat mosaic: identification and mapping
Resumo O Mosaico de Habitat Móvel (SHM) refere-se às mudanças temporais no padrão espacial dos habitats, através dos pulsos de inundação e seca. Este trabalho teve por objetivo mapear a dinâmica de um Mosaico Móvel associado aos pulsos de inundação e seca, na Área de Proteção Ambiental do Banhado Grande (APABG). A realização desta pesquisa di

7. Mapping Soil Cation Exchange Capacity in a Semiarid Region through Predictive Models and Covariates from Remote Sensing Data
ABSTRACT: Planning sustainable use of land resources requires reliable information about spatial distribution of soil physical and chemical properties related to environmental processes and ecosystemic functions. In this context, cation exchange capacity (CEC) is a fundamental soil quality indicator; however, it takes money and time to obtain this data. Alth

8. 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

9. Effect of Activated Carbons on the Dielectric and Microwave Properties of Natural Rubber Based Composites
The effect of six different types of activated carbons has been studied in view of their applicability as functional fillers upon the dielectric and microwave properties of natural rubber based composites. It is found that the textural characteristics of the studied active carbons exert influence both on the real part of dielectric permittivity and dielectri

10. Hippocampal overexpression of Down syndrome cell adhesion molecule in amyloid precursor protein transgenic mice
Down syndrome cell adhesion molecule (DSCAM) is located within the Down syndrome critical region of chromosome 21. DSCAM is a broadly expressed neurodevelopmental protein involved in synaptogenesis, neurite outgrowth, and axon guidance. We previously demonstrated DSCAM overexpression in the cortex of amyloid precursor protein (APP) transgenic mice, suggestin

12. MALDI Imaging Mass Spectrometry of Fresh Water Cyanobacteria: Spatial Distribution of Toxins and Other Metabolites
Cyanobacteria are among the most ancient forms of life, yet they are known to synthesize highly sophisticated defense molecules, such as the highly hepatotoxic cyclic peptides microcystins and nodularins produced by the genera Microcystis, Anabaena and Nodularia. These metabolites are released by cyanobacteria to water environments causing episodes of fatali
