13. Ground motions for FEMA P-695 application in subduction zones
Abstract The FEMA P-695 report presents a methodology for the rational quantification of seismic performance factors for use in seismic design. Despite the fact that the methodology is comprehensive and covers a wide range of possible applications, it only provides ground motion sets recorded from shallow crustal earthquakes. Therefore, this paper presents a

15. 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

16. Molten Salt Synthesis of Bi2WO6 Powders and its Visible-Light Photocatalytic Activity
Bi2WO6 powders were synthesized by the molten salt method at 250-350 ºC using the mixture of Bi(NO3)3·5H2O and Na2WO4·2H2O as a precursor, and the mixture of LiNO3 and NaNO3 with a molar ratio of 27:33 as a molten salt, respectively. The effects of temperature and salt amount on the phase composition, morphology and photocatalytic activity under the visib

17. Preparation and Luminescence Properties of Europium(III) Ternary Complex-modified Poplar Wood-based Materials
Inspired by the ultraviolet induced properties of biological materials, we developed fluorescent wood as a new type of functional material which can be applied to anti-counterfeit label technology and wood-emitting artwork. This study discusses the influence of temperature, time, ligand ratio, and reactant concentration on the structure and properties of flu

19. Towards the micropropagation of Euphorbia cyathophora Murray: a wild plant species with medicinal and ornamental potential
RESUMO: Euphorbia cyathophora Murray é uma espécie vegetal com potencial medicinal e ornamental, mas cuja propagação in vitro é desconhecida. Dois experimentos foram realizados para conhecer 1) o efeito da luz (WL) a 25±2 °C e 20 μmol m-2 s-1 intensidade luminosa, ou escuridão a 20±2 °C, nos primeiros 20 dias e posterior colocação em luz (DKL)

20. The Role of Environmental Heterogeneity in the Seed Rain Pattern
ABSTRACT We focus on understanding the influence of environmental variables on ecological processes, and such a focus promotes an integrated view of forest ecological patterns. The following questions were made: Do variations in temperature, precipitation, litterfall deposition and light intensity influence the density and composition of seed rain in a stret

21. Estudo da atividade estelar da Kepler-289 a partir da modelagem de trânsitos planetários
Resumo Neste trabalho apresentamos um estudo sobre atividade estelar e trânsitos planetários de exoplanetas. Sem apresentar rigor matemático demostramos como obter parâmetros físicos como: temperatura, intensidade e posição de manchas em superfície de estrelas do tipo solar, bem como, a rotação estelar média a partir de dados públicos da Missão

22. In vitro adventitious shoot regeneration from leaf explants of some apricot cultivars
RESUMO O damasco é considerado uma das frutas mais valiosas comercialmente. A propagação in vitro de damasco é muito importante para a multiplicação de cultivares com características desejáveis, saudáveis e livres de vírus. O fator limitante para a propagação por métodos convencionais é a baixa frequência na multiplicação. Nesse contexto, o

24. WATER AND LIGHT STRESSES DRIVE ACCLIMATION DURING THE ESTABLISHMENT OF A TIMBER TREE UNDER DIFFERENT INTENSITIES OF RAINFOREST CANOPY COVERAGE
ABSTRACT The loss of structure, diversity and functions in the rainforests makes it necessary to develop active strategies to restore their economic and ecological values. Planting selected species can help to catalyze ecosystem restoration. The capacity of the plants to survive and grow in the rainforests, where the canopy coverage changes stochastically, i
