    PurposeIn the literature, 65 years is commonly used as the age to designate an older person in the community. When studying older prisoners, there is much variation. The purpose of this paper is to investigate how researchers define older offenders and for what reasons.Design/methodology/approachThe authors reviewed articles on health and well-being of older offenders to assess terminology used to describe this age group, the chosen age cut-offs distinguishing younger offenders from older offenders, the arguments provided to support this choice as well as the empirical base cited in this context.FindingsThe findings show that the age cut-off of 50 years and the term "older" were most frequently used by researchers in the field. The authors find eight main arguments given to underscore the use of specific age cut-offs delineating older offenders. They outline the reasoning provided for each argument and evaluate it for its use to define older offenders.Originality/valueWith this review, it is hoped to stimulate the much-needed discussion advancing towards a uniform definition of the older offender. Such a uniform definition would make future research more comparable and ensure that there is no ambiguity when researchers state that the study population is "older offenders"

    Polypyridyl Ru( ii )-derivatized polypropylacrylate polymer with a terminal water oxidation catalyst. Application of reversible addition–fragmentation chain transfer polymerization

    A Ru(II) polypyridyl-derivatized polypropylacrylate end-capped with a water-oxidation-catalyst (WOC) has been synthesized by using reversible addition–fragmentation chain transfer polymerization (RAFT) followed by click reaction and end-group functionalization. In cyclic voltammograms in propylene carbonate, chromophore oxidation occurs at 1.27 V vs. NHE and the RuIII/II wave for the catalyst at 0.84 V vs. NHE. Upon excitation of the Ru(II) chromophore, excited-state energy migration occurs by site-to-site, –RuII*– → –RuII–, energy transfer hopping along the polymer chain, in part, reaching the terminal catalyst site where –RuII*– → –RuII–OH2 2+ energy transfer is favored by ΔGen = −2100 cm−1. Added MV2+ as an electron transfer acceptor oxidizes the –RuII*– excited state on the polymer to Ru(III), –RuII*– + MV2+ → –RuIII– + MV+ , and ultimately, the catalyst, by site-to-site electron transfer hopping and oxidation, -RuIII-← e-RuII - OH2 2+. Oxidation is followed by relatively slow, diffusional back electron transfer from MV•+ to Ru(III) sites on the polymer chain. The mixed chromophore-catalyst polymer is a water oxidation catalyst with potential for enhanced light harvesting and water oxidation

    Asian soybean rust, caused by the fungus Phakopsora pachyrhizi, is the most severe disease of the crop and can cause yield losses of up to 90%. The disease was first reported in Brazil in 2001. Epidemics of the disease are common in the country, where the fungus can survive year‑round. Regulatory measures to reduce the inoculum between seasons and avoid late-season soybean have been adopted to manage the disease. Disease control has relied mainly on chemical control, but a lower sensibility of the fungus to fungicides has been reported in Brazil. Major‑resistance genes have been mapped and incorporated into the cultivars. With the reduced efficacy of the fungicides, the adoption of integrated measures to control the disease will be important for the sustainability of the crop. This review presents the main changes in the soybean crop system caused by the introduction of the fungus in Brazil, the current management strategies adopted to avoid losses, and the new trends that, together with biotechnological strategies, can improve management in the future.A ferrugem‑asiática da soja, causada pelo fungo Phakopsora pachyrhizi, é a doença mais severa da cultura e pode causar perdas de produtividade de até 90%. A doença foi relatada pela primeira vez no Brasil em 2001. Epidemias da doença são comuns no País, onde o fungo pode sobreviver durante todo o ano. Medidas regulatórias para reduzir o inóculo entre safras e evitar a semeadura tardia de soja têm sido adotadas para manejar a doença. O controle da doença tem se baseado principalmente no controle químico, mas uma menor sensibilidade do fungo aos fungicidas tem sido relatada no Brasil. Genes de resistência têm sido mapeados e incorporados às cultivares. Por causa da redução da eficiência dos fungicidas, a adoção de medidas integradas para o controle da doença será importante para a sustentabilidade da cultura. Este artigo de revisão apresenta as principais mudanças no sistema de produção da soja causadas pela introdução do fungo no Brasil, as medidas de controle atualmente usadas para evitar perdas, e as novas tendências que, juntas com estratégias biotecnológicas, podem melhorar o manejo da doença no futuro

    Shipwreck ecology:Understanding the function and processes from microbes to megafauna

    Get PDF
    An estimated three million shipwrecks exist worldwide and are recognized as cultural resources and foci of archaeological investigations. Shipwrecks also support ecological resources by providing underwater habitats that can be colonized by diverse organisms ranging from microbes to megafauna. In the present article, we review the emerging ecological subdiscipline of shipwreck ecology, which aims to understand ecological functions and processes that occur on shipwrecks. We synthesize how shipwrecks create habitat for biota across multiple trophic levels and then describe how fundamental ecological functions and processes, including succession, zonation, connectivity, energy flow, disturbance, and habitat degradation, manifest on shipwrecks. We highlight future directions in shipwreck ecology that are ripe for exploration, placing a particular emphasis on how shipwrecks may serve as experimental networks to address long-standing ecological questions.</p

    Visible photoelectrochemical water splitting into H 2 and O 2 in a dye-sensitized photoelectrosynthesis cell

    Mesoporous SnO2/TiO2 core/shell nanostructured electrodes derivatized with a surface-bound Ru(II) polypyridyl-based chromophore–catalyst assembly are used for water splitting into H2 and O2 with visible light in a dye-sensitized photoelectrosynthesis cell. Photocurrents with a small applied bias are among the highest reported. Stabilization of the assembly on the surface of the TiO2 shell by using atomic layer deposition to deposit overlayers of Al2O3 or TiO2 results in long-term water splitting even in a phosphate buffer at pH 7

    http://dx.doi.org/10.5902/1980509820595This study aimed to characterize the remnants of Ombrophilous Dense Forest in Santa Catarina state. The dataset used in this study was provided by Project of Floristic and Forest Inventory of Santa Catarina, coming from 197 sample units that consist of basic clusters. The basic cluster was composed of four subunits of 20 x 50 m, in which all individuals with DBH ≥ 10 cm were measured. The forest structure was characterized through phytosociological parameters and indices. Based on structural data of the species, cluster analysis and ordination were performed in an attempt to identify groups of watersheds and altitude ranges. It was identified 577 species belonging to 226 genera and 83 families. The most representative families in number of species and individuals were Myrtaceae, Lauraceae and Fabaceae. Species of disturbed areas as Alchornea triplinervia, Caseria sylvestris and Miconia cinnamomifolia were dominant in the forest. Cluster analysis resulted in the identification of three vegetation types along the altitudinal gradient: Lowland Ombrophilous Dense Forest (&lt; 30 m a.s.l.), Submontane (30 - 500 m) and Montane (&gt; 500 m). Floristic and structural variations could be detected between the three vegetation types. In lowland communities, the presence of Anacardiaceae and Clusiaceae was more expressive and the average height of trees was higher. In montane environments, there was an increase in the number of individuals, basal area and diversity, as well as a greater representation of Cyatheaceae, Lauraceae and Rubiaceae. The occurrence of Arecaceae was remarkable in submontane forest. Spatial groups could not be defined based on structural data of watersheds.http://dx.doi.org/10.5902/1980509820595O presente trabalho teve por objetivo caracterizar os remanescentes da Floresta Ombrófila Densa, no estadode Santa Catarina.
