Myrceugenia euosma (O. Berg) D. Legrand (Myrtaceae) tem porte arbóreo ou arbustivo, com ocorrência na América do Sul, principalmente no Chile e no sul do Brasil. Objetivou-se estudar a morfologia de fruto, semente e plântula, e a germinação de sementes desta espécie. Os frutos foram coletados de cinco matrizes em remanescente de Floresta Ombrófila Mista Aluvial em Araucária – PR. Foi testada a influência de diferentes substratos (papel, rolo de papel e areia), temperaturas (20 ºC, 25 ºC e 30 ºC) e condições de luz (presença e ausência) sobre a germinação das sementes. M. euosma tem fruto do tipo baga, contendo de 2 a 13 sementes, envolvidas por tegumento membranáceo, com endosperma mucilaginoso, evidente apenas na germinação. O embrião é mircióide, típico da subtribo Myrciinae, e a plântula é epígea, fanerocotiledonar. A germinação tem início entre três e cinco dias e, com exceção do substrato rolo de papel na temperatura 30ºC, os demais tratamentos apresentaram percentuais relativamente altos de germinação (≈ 72%). As sementes são fotoblásticas neutras. Os resultados indicam que M. euosma tem poucas restrições em termos reprodutivos quanto à germinação.Palavras-chave: Myrciinae, Floresta Ombrófila Mista, Floresta com Araucária. AbstractMorphology of fruit, seed and seedling and seed germination of Myrceugenia euosma (O. Berg) D. Legrand (Myrtaceae). Myrceugenia euosma is a tree or shruby species that occurs in South America in two major centers: Chile and south of Brazil. The objective of this work was to study the morphology of the fruit, seed and seedling and the seed germination of this species. Fruit, seed and seedling were illustrated and described. The influence of three substrates (paper towels, paper roll and sand), temperatures (20 ºC, 25 ºC and 30 ºC) and conditions of light (presence and absence) over the seed germination were evaluated. The fruit of M. euosma is a berry, containing 2 to 13 seeds. The seed has membranaceous tegument, small amount of mucilaginous endosperm, evident only in germination, and embryo typical of the subtribe Myrciinae. The seedling is epigea, phanerocotylar, with paracotyledons and eophylls simple, opposites. Germination started three to five days after the test installation. Almost all treatments resulted in relatively high germination percentage (≈72%), except in paper roll at 30ºC (43%). The species germinates in the absence of light. The results indicate that M. euosma has few reproductive restrictions with regard to germination.Keywords: Myrciinae, Mixed Ombrophylous Forest , Araucaria forest.

HIPERTEXTO, LITERATURA AFRO-BRASILEIRA E LEITURA LITERÁRIA
Authors: Dos Santos José Alexandre , Santos Jeane De Cassia Nascimento 
Published: January 2018

Refletimos neste trabalho sobre a alternativa de o professor de literatura, no ensino básico, promover letramento literário através de hipertextos, considerando que a sociedade contemporânea proporciona, aos docentes e discentes, acesso às tecnologias digitais e à internet, diariamente, aspecto que reforça a convivência de ambos com esses meios de comunicação e que, em alguns casos, gera uma relação de dependência. Apoiamos, por conseguinte, em teóricos como Levy (1993), Koch (2002), e Xavier (2004). Aceitamos as convergências existentes entre hipertexto e literatura, tendo como suporte a opinião de autores que consideram a intertextualidade, aspecto relevante para o estudo de literatura, uma característica fundamental da hipertextualidade, além de servir como suporte à construção de um conhecimento interdisciplinar, conforme podemos perceber nas teorias elaboradas por Baktin (2003), Kristeva (1974), Kleiman e Moraes (1999). Por fim, sugerimos um trabalho de letramento em literatura afro-brasileira, considerando os conceitos de Zilberman (1993), Cosson (2009), Aguiar e Bordini (1993), Duarte (2010) e Bernd (2011); os estudos teóricos de Munanga (2005), Souza e Crosso (2007), as orientações dos PCNs (2000) e a Lei 10.639/03.

Dette nummer af Passage fokuserer på de erkendelsesmæssige og metodiske udfordringer, der går på tværs af litteraturen og videnskaberne. Hvordan har litteraturen sat videnskabernes usikkerheder og forhindringer under luppen? I hvilken grad bygger den faktuelt orienterede videnskab på narrativer, billeder og figurer fra fiktionens verden? Med et perspektiv fra baglokalets vanskelige eksperimenter snarere end de polerede faktas strålende udstillingslokale, prøver nummeret at opridse et større vidensfelt, der inkluderer både ånds- og naturvidenskaberne. Dette nummer af Passage tegner en linje fra undersøgelsen af, hvordan litteraturen og videnskaberne former hinanden til stadig mere eksplicitte refleksioner over, hvordan den gensidige infiltrering samtidig skaber usikkerhed og prekær viden. Det peger også på en vanskelig, men frugtbar udvidelse af vidensbegrebet fra de traditionelt videnskabelige felter til også at inkludere fx venskabet, narrativer og kunstnerisk praksis. Dermed tilbyder det ingen entydige svar på forholdet mellem litteratur, viden og videnskab. Til gengæld opridser det et større problemfelt, hvis interne overlap, forskelle og udviklinger netop kan synliggøres og klarlægges.

AbstractMagma is transported in brittle rock through dikes and sills. This movement may be accompanied by the release of seismic energy that can be tracked from the Earth's surface. Locating dikes and deciphering their dynamics is therefore of prime importance in understanding and potentially forecasting volcanic eruptions. The Seismic Amplitude Ratio Analysis (SARA) method aims to track melt propagation using the amplitudes recorded across a seismic network without picking the arrival times of individual earthquake phases. This study validates this methodology by comparing SARA locations (filtered between 2 and 16 Hz) with the earthquake locations (same frequency band) recorded during the 2014–2015 Bár
arbunga‐Holuhraun dike intrusion and eruption in Iceland. Integrating both approaches also provides the opportunity to investigate the spatiotemporal characteristics of magma migration during the dike intrusion and ensuing eruption. During the intrusion SARA locations correspond remarkably well to the locations of earthquakes. Several exceptions are, however, observed. (1) A low‐frequency signal was possibly associated with a subglacial eruption on 23 August. (2) A systematic retreat of the seismicity was also observed to the back of each active segment during stalled phases and was associated with a larger spatial extent of the seismic energy source. This behavior may be controlled by the dike's shape and/or by dike inflation. (3) During the eruption SARA locations consistently focused at the eruptive site. (4) Tremor‐rich signal close to ice cauldrons occurred on 3 September. This study demonstrates the power of the SARA methodology, provided robust site amplification; Quality Factors and seismic velocities are available.

Published: January 2018

AbstractTwo‐dimensional (2D) materials have been demonstrated as promising building blocks in future electronic and their mechanical properties are quite important for various applications. Due to their atomic thickness and planar nature, the investigation of the mechanical properties and related atomic mechanism are quite challenging. This review focuses on the recently developed in situ techniques based on scanning electron microscopy (SEM), transmission electron microscopy (TEM), and atomic force microscopy (AFM) in characterization of the mechanical properties of 2D materials. In situ methods used for studying their elastic properties, fracture behavior, and surface/interface energy are introduced in detail. Specifically, the AFM indentation test and microelectromechanical systems (MEMS) device are generally used to investigate the elastic properties; the manipulator based methods show their flexibility in studying the fracture, adhesion, cleavage, and friction properties; atomic level fracture mechanism can be revealed with in situ high resolution TEM (HRTEM); the pressurized blister test and the buckle/wrinkle based methods are widely used to measure the surface/interface properties. Moreover, the influence of sample preparation process, defects and layer numbers to their mechanical properties are also discussed. Finally, the extensions of above methods to investigate the strain‐modulated physical properties of 2D materials are introduced.
Solar‐Light‐Driven CO2 Reduction by CH4 on Silica‐Cluster‐Modified Ni Nanocrystals with a High Solar‐to‐Fuel Efficiency and Excellent Durability

Published: January 2018

AbstractCatalytic CO2 reforming of CH4 (CRM) to produce syngas (H2 and CO) provides a promising approach to reducing global CO2 emissions and the extensive utilization of natural gas resources. However, the rapid deactivation of the reported catalysts due to severe carbon deposition at high reaction temperatures and the large energy consumption of the process hinder its industrial application. Here, a method for almost completely preventing carbon deposition is reported by modifying the surface of Ni nanocrystals with silica clusters. The obtained catalyst exhibits excellent durability for CRM with almost no carbon deposition and deactivation after reaction for 700 h. Very importantly, it is found that CRM on the catalyst can be driven by focused solar light, thus providing a promising new approach to the conversion of renewable solar energy to fuel due to the highly endothermic characteristics of CRM. The reaction yields high production rates of H2 and CO (17.1 and 19.9 mmol min−1 g−1, respectively) with a very high solar‐to‐fuel efficiency (η, 12.5%). Even under focused IR irradiation with a wavelength above 830 nm, the η of the catalyst remains as high as 3.1%. The highly efficient catalytic activity arises from the efficient solar‐light‐driven thermocatalytic CRM enhanced by a novel photoactivation effect.
Mechanical Property Evolution of Silicon Composite Electrodes Studied by Environmental Nanoindentation

Published: January 2018

AbstractMechanical degradation is largely responsible for the short cycle life of silicon (Si)‐based electrodes for future lithium‐ion batteries. An improved fundamental understanding of the mechanical behavior of Si electrodes, which evolves, as demonstrated in this paper, with the state of charge (SOC) and the cycle number, is a prerequisite for overcoming mechanical degradation and designing high capacity and durable Si‐based electrodes. In this study, Young's modulus (E) and hardness (H) of Si composite electrodes at different SOCs and after different cycle numbers are measured by nanoindentation under both dry and wet (liquid electrolyte) conditions. Unlike electrodes made of Si alone, E and H values of Si composite electrodes increase with increasing Li concentration. The composite electrodes under wet conditions are softer than that under dry conditions. Both E and H decrease with the cycle number. These findings highlight the effects of porosity, liquid environment, and degradation on the mechanical behavior of composite electrodes. The methods and results of this study on the mechanical property evolution of Si/polyvinylidene fluoride electrodes form a basis for exploring more effective binders for Si‐based electrodes. Furthermore, the evolving nature of the mechanical behavior of composite electrodes should be taken into consideration in future modeling efforts of porous composite electrodes.
