Abstract Terrestrial runoff is a source of sediments and nutrients to coral reefs. Due to runoff, Brazilian reefs are typically turbid, and have coral species that are naturally turbidity-resistant. This study investigated how terrestrial input influences population and physiology for the coral Favia gravida on two reefs with differences in river mouth proximity in eastern Brazil. The population structure and physiological traits of F. gravida colonies were assessed on both reefs, then some colonies selected for a subsequent transplantation experiment. The reef less impacted by terrestrial influence showed higher population density and lower recruitment. At this site, the coral colonies displayed higher calcification and larger larvae. The reproductive effort between coral populations at the two sites showed no significant difference. The transplantation experiment confirmed the high physiological plasticity of F. gravida colonies at the more turbid reef site. Despite being regarded as a more challenging environment, where F. gravida has a lower population density, the reef closer to the river mouth appears to secure more nutrients, which may heterotrophically compensate its coral colonies.

ABSTRACT Larvae of many-plumed moths (Alucitidae), especially in the world-wide genus Alucita Linnaeus, 1758 are known as borers or gall-inducers on flowers, fruits and shoots of a few dicotyledonous families, including Bignoniaceae, Caprifoliaceae and Rubiaceae. However, there is no study available on the biology of the monotypic, Neotropical genus Prymnotomis Meyrick, 1931 except for its original description that was based on a single male, the holotype of Prymnotomis crypsicroca Meyrick, 1931 from Espirito Santo, Brazil. We describe here a second species for this genus, Prymnotomis cecidicola sp. nov. whose larvae induce galls on Cordiera elliptica (Cham.) Kuntze (Rubiaceae), a dioecious plant with dimorphic inflorescences found in the Brazilian Cerrado, Planaltina City, Federal District. Adults, larvae, pupae and galls are illustrated under light and scanning electron microscopy. Galls are green, spherical, unilocular and develop individually on C. elliptica flower buds. During development they look like fruits in shape and colour but are larger, do not have style scars when on female plants, and are induced also in male inflorescences. Pupation occurs outside the gall within a silk cocoon, presumably in the litter. A preliminary analysis of DNA barcode sequences including putative members of other alucitid lineages and Neotropical BINs (Barcode Index Number) supports Prymnotomis cecidicola sp. nov. as an independent phylogenetic unit, with 12 to 18% divergence. Its nearest-neighbour was the BIN cluster 5 (BOLD:AAA0842) that includes specimens from Costa Rica.

ABSTRACT Stigmella schinivora van Nieukerken, 2016 was described from Cataratas de Iguazú, Misiones, Argentina, based on adults reared from Schinus terebinthifolius Raddi (Anacardiaceae) leaf mines. The aim of this study is to describe for the first time the external morphology of the immature stages of S. schinivora with the aid of light and scanning electron microscopy, based on mines collected on the same host plant, but in Laranjeiras do Sul, Paraná, Brazil. Data on natural history, including histology of the mines, are also provided. The larva passes through four instars, all endophytic, having chewing mouth parts and feeding on the palisade parenchyma. The first three instars are apodous and have a subcylindrical body, bearing only one pair of setae on the tenth abdominal segment; the fourth instar is eruciform, with well-developed ambulatory calli on thorax and abdomen and setae on all tagmata. A serpentine mine is constructed on the adaxial surface, progressively increasing in width during larval development. With the exception of the widened, terminal section, the mine is left filled with larval feces. The fully developed larva of last instar exits through a slit made at the distal end of the mine, building a silk cocoon on the leaf abaxial surface where pupation occurs. This is the first record of S. schinivora from Brazil, which was only known from the type locality in Argentina.

ABSTRACT The Neotropical micromoth genus Leurocephala Davis & Mc Kay, 2011 (Lepidoptera, Gracillariidae) was originally described to include only the type species, L. schinusae Davis & Mc Kay, 2011, whose leaf miner larvae are associated with Anacardiaceae in Argentina, Brazil and Paraguay. An integrative analysis including morphology, life history and DNA barcode sequences revealed that specimens collected on Schinus molle L. (Anacardiaceae) in the coastal valleys of the Atacama Desert of northern Chile belong to a second species of this formerly monotypic genus. Adults of Leurocephala chilensis Vargas & Moreira sp. nov. are herein described and illustrated in association with the immature stages and life history, and corresponding phylogenetic relationships are assessed based on DNA barcode sequences. This finding provides the first record of Leurocephala from west of the Andes Range, expanding remarkably its geographic range. It is suggested that the extent of diversity within Leurocephala is much greater and that variation in geographic factors and host plant use may have modeled it, an evolutionary hypothesis that should be assessed in further studies.

A Governança Corporativa das Tecnologias de Informação é uma temática primordial reconhecida pela comunidade académica e profissional. A necessidade de obter valor, seja financeiro ou estratégico para a organização, resultante dos investimentos realizados em TI implica uma Gestão do Valor das TI adequada. As dificuldades ou o pouco know-how das empresas na implementação de práticas propostas por Frameworks elaborados pela comunidade profissional, como o Val IT 2.0 ou o COBIT, 5 levam as organizações a optar pelo desenvolvimento de modelos próprios. Este artigo identifica um conjunto de práticas e recursos de Gestão do Valor das TI, resultantes da integração do VAL IT 2.0 no COBIT 5, usando uma metodologia de investigação baseada numa revisão da literatura, que suportará o desenho de um modelo conceptual para identificação de um conjunto de habilitadores de Gestão do Valor das TI presentes no COBIT 5.

Enterprise Governance of Information Technology is a primary theme recognized by the academic and professional community. The need for value to the organization, whether strategic or financial, resulting from investments made in IT implies an appropriate IT Value Management. The difficulties or the little know-how in the implementation of practical Frameworks proposed by the professional community like Val IT 2.0 or COBIT 5 lead organizations opt for the development of their own models. This paper identifies a set of practices and resources of IT Value Management resulting from the integration of VAL IT 2.0 in COBIT 5. A research methodology based on a literature review, will support the design of a conceptual model for identifying a set of enablers of IT Value Management present in COBIT 5.

CONTEXTO: Trabalho realizado na área de cirurgia vascular, porém relevante a todas as especialidades clínicas e cirúrgicas devido à importância clínica da trombose venosa profunda e sua principal complicação, a embolia pulmonar. OBJETIVOS: Verificar se a profilaxia para a trombose venosa profunda está sendo utilizada de forma adequada e rotineira em nosso serviço e avaliar o conhecimento dos médicos sobre as indicações de profilaxia medicamentosa. MÉTODOS: Foi realizado um estudo prospectivo com 850 pacientes internados de março a maio de 2007 no Hospital Geral de Roraima. Foram pesquisados fatores clínicos, medicamentosos e cirúrgicos. A estratificação de risco e a avaliação da profilaxia foram estabelecidas conforme a classificação recomendada pela Sociedade Brasileira de Angiologia e Cirurgia Vascular e o protocolo realizado por Caiafa em 2002. Os médicos responderam a um questionário e analisaram três casos clínicos hipotéticos. Os dados foram tabulados e analisados estatisticamente usando o programa de computador Epi-Info 2002®. RESULTADOS: Dos 850 pacientes estudados, 557 (66,66%) eram clínicos e 293 (33,34%) cirúrgicos. Do total, 353 pacientes (41,56%) foram classificados como baixo risco, 411 (48,32%) como médio risco e 86 (10,12%) como alto risco para desenvolver trombose venosa profunda. Dos 497 pacientes que necessitavam receber profilaxia medicamentosa para trombose venosa profunda, apenas 120 (24%) a receberam; destes, 102 (85%) a receberam de forma correta. Dos que não necessitavam de profilaxia, nenhum a recebeu. Os clínicos prescreveram mais e de forma mais correta a profilaxia em relação aos cirurgiões, apesar de estes terem demonstrado possuir um melhor conhecimento teórico do tema. No geral, o conhecimento teórico sobre trombose venosa profunda foi insuficiente. CONCLUSÕES: Em nosso serviço, a profilaxia medicamentosa da trombose venosa profunda é subutilizada em pacientes com indicação para recebê-la, tornando necessária a implementação de um programa de educação continuada sobre o tema.

BACKGROUND: Although this work belongs to the area of vascular surgery, it is relevant to all clinical and surgical specialties due to the clinical importance of deep venous thrombosis and its main complication, pulmonary embolism. OBJECTIVES: To verify whether pharmacological prophylaxis of deep venous thrombosis is being adequately and routinely used in our service and to evaluate physicians' knowledge about the indications of deep venous thrombosis chemoprophylaxis. METHODS: A prospective study was accomplished including 850 patients hospitalized from March to May 2007 at Hospital Geral de Roraima. Clinical, pharmacological and surgical factors were researched. Risk stratification and evaluation of prophylaxis were established according to the classification suggested by the Brazilian Society of Angiology and Vascular Surgery and to the protocol developed by Caiafa in 2002. Physicians answered a questionnaire and analyzed three hypothetical clinical cases. Data were tabled and statistically analyzed with the support of the software Epi-Info 2002®. RESULTS: Of the 850 patients surveyed, 557 (66.66%) were clinical and 293 (33.34%) were surgical patients. Of the total, 353 (41.56%) had low risk, 411 (48.32%) medium risk and 86 (10.12%) high risk for development of deep venous thrombosis. Of the 497 patients that needed to receive chemoprophylaxis for deep venous thrombosis, only 120 (24%) received it and of these, 102 (85%) received it adequately. Any patient who did not need prophylaxis received it. Clinical physicians prescribed prophylaxis more frequently and correctly than surgeons, although the latter have demonstrated better theoretical knowledge of the theme. In general, theoretical knowledge on deep venous thrombosis was insufficient. CONCLUSIONS: In our hospital, chemoprophylaxis for deep venous thrombosis is underused in patients indicated for receiving it. Therefore, it is necessary to implement a continuous education program about this theme.

With the development of industrialized steel construction, new constructive elements have been brought not only to the market, but to the everyday construction site as well and, in this way professionals and users have questioned their efficiency. In respect to vibrations in floors, what can be detected is that floor structures are thinner and a decrease of the mass in the horizontal closing panels and the utilization of new materials and systems have led them to have lower natural frequencies, and so are nearer to the frequencies produced by walking. This decrease of mass of the closing panels also lead to a considerable weakness in terms of acoustical insulation, which can cause unfavorable conditions and discomfort. Thus, it becomes necessary to do detailed studies of the efficiency of the vibration and acoustical performance of the new systems to obtain the characterization and the qualification parameters in order to optimize their use. This study does a comparative evaluation of some kinds of horizontal and vertical closing systems in respect to the vibrational and acoustical insulation performance.

Esse trabalho apresenta um estudo sobre os níveis de vibrações relacionados à percepção e ao conforto humano. Portanto o objetivo principal desse trabalho é gerar curvas de percepção e conforto humano quanto à vibração através de experimentos de laboratório. As respostas para vibração vertical senoidal de 30 voluntários (15 homens e 15 mulheres) são determinadas para freqüências no intervalo de 12 a 80 Hz. O primeiro experimento tem por objetivo a determinação do limite de percepção à vibração, realizando-se, também, uma análise sobre o intervalo de incerteza das respostas. O segundo experimento corresponde à determinação da relação entre o limite de conforto e o de percepção, considerando-se ambientes residenciais. Uma análise sobre o efeito da postura também é realizada. Não foram encontradas diferenças significativas entre os resultados para homens e mulheres. Para o limite de percepção, os resultados se apresentam em conformidade com a norma internacional ISO 2631/2 (1989) para a postura sentada, ocorrendo diferenças significativas para a postura em pé. Os resultados para o limite de conforto em ambientes residenciais se apresentam entre 2 a 4 vezes superiores ao limite de percepção.

This work presents a study on vibration levels in connection with human comfort and perception. The main objective here was to experimentally generate human-comfort and perception curves as a function of vertical sinusoidal vibrations. Thirty volunteers (15 men and 15 women) and a frequency range varying from 12 to 80 Hz were considered in the experiments. The goal of the first experiment was to determine the vibration-perception limits. Also measured was the uncertainty interval of the analysis. The second experiment was related to the determination of the relation between the perception and comfort limit, taking into account residential areas. The effects of posture on the results are also investigated. No significant differences were found between the results for men and women. Furthermore, the perception limit for seated persons is in accordance with the ISO 2631/2 (1989). On the other hand, significant differences were found for the standing posture. The results for the human-comfort limit in residential areas are found to be 2 to 4 times greater than the experimentally measured perception limit.
