Published: May 2017

Abstract
We present the narrow emission-line structure revealed by a 135 ks Chandra observation of Seyfert galaxy NGC 2992, using the High Energy Transmission Grating Spectrometer. The source was observed in an historically low-flux state. Using a Bayesian Block search technique, we detected neutral Si Kα and S Kα fluorescence and two additional lines that are consistent with redshifted, ionized Si emission. The latter two features are indicative of a photoionized outflow with a velocity of

. We also observed prominent, unresolved line emission at the rest energy of Fe Kα, with a 90% confidence FWHM velocity width of

(

) and equivalent width of 406–1148 eV (288–858 eV) when broad Fe Kα line emission, as detected by Suzaku, was (was not) included in the model.
Direct Ejecta Velocity Measurements of Tycho's Supernova Remnant
Authors: Sato Toshiki , Hughes John P. 
Published: May 2017

Abstract
We present the first direct ejecta velocity measurements of Tycho’s supernova remnant (SNR). Chandra’s high angular resolution images reveal a patchy structure of radial velocities in the ejecta that can be separated into distinct redshifted, blueshifted, and low velocity ejecta clumps or blobs. The typical velocities of the redshifted and blueshifted blobs are ≲7800 and ≲5000 km s−1, respectively. The highest velocity blobs are located near the center, while the low velocity ones appear near the edge as expected for a generally spherical expansion. Systematic uncertainty on the velocity measurements from gain calibration was assessed by carrying out joint fits of individual blobs with both the ACIS-I and ACIS-S detectors. We determine the three-dimensional kinematics of the Si- and Fe-rich clumps in the southeastern (SE) quadrant and show that these knots form a distinct, compact, and kinematically connected structure, possibly even a chain of knots strung along the remnant’s edge. By examining the viewing geometries, we conclude that the knots in the SE region are unlikely to be responsible for the high velocity Ca ii absorption features seen in the light-echo spectrum of SN 1572, the originating event for Tycho’s SNR.

Objective.To describe the experience of the first-time participant (newbie) training program at the Outcome Measures in Rheumatology (OMERACT) 2016 meeting.Methods.We conducted new participant sessions at OMERACT 2016, including a 2-h introductory session on Day 1 followed by 1-h evening followup sessions on days 1–4. Pre- and post-meeting surveys assessed participants’ levels of comfort with the principles of the OMERACT Filter 2.0 (the essential tools for OMERACT methodology) and the different types of OMERACT sessions, and whether participants felt welcome. In addition, on the final day, a nominal group technique was used to elicit problematic components of the meeting and to develop solutions to those problems.Results.Of the 43 new attendees, 38 participated in the introductory session and 14–18 attended the followup sessions. Comparing Day 1 (preintroductory session) to days 1–3 (post), a similar proportion understood different types of sessions extremely well [45% (pre) versus 47%, 44%, and 36% (post), respectively], and a higher proportion understood principles of the OMERACT filter extremely well [22% (pre) versus 55%, 44%, and 40% (post), respectively]. Most reported feeling welcome (86.7%) and felt they contributed to breakout sessions (93.3%) on the evening of Day 1; results were sustained on days 2–3. The most commonly reported “best” experience included the OMERACT culture and the most common reported experience needing improvement included facilitation issues during breakouts.Conclusion.The first-time participants came to OMERACT 2016 with a high baseline level of understanding. They rapidly attained a high comfort level with participation and provided concrete and innovative solutions to the most commonly reported experiences needing improvement.

RESUMO Este estudo teve como objetivo investigar a influência do conhecimento, utilização e grau de importância empregado às ferramentas de controle gerencial no desempenho das organizações de cunho industrial com atuação no estado do Paraná. Quanto ao design metodológico esta pesquisa é descritiva, de levantamento e quantitativa. A população objeto de estudo compreendeu 1809 empresas cadastradas na Federação das Indústrias do Estado do Paraná (FIEP), e a amostra aleatória é constituída de 149 empresas. O instrumento de coleta de dados se deu por intermédio de questionário que abordou questões referentes às seguintes ferramentas de controle gerencial: planejamento estratégico formal, orçamento, custeio por absorção, custeio baseado em atividades, gestão baseada em atividades, custeio variável, custeio alvo, balanced scorecard, análise custo/volume/lucro, análise de lucratividade do produto (margem de contribuição), análise da cadeia de valor, análise do ciclo de vida do produto, técnicas de orçamento de capital, análise de medidas econômicas de desempenho (EVA, Lucro Residual), e demonstrações contábeis básicas. Para análise dos dados utilizou-se a estatística descritiva e o Teste Chi- Square. Pela análise dos resultados foi possível perceber que a maioria dos gestores conhecem as ferramentas de controles gerenciais, porém há um baixo percentual de utilização destas e muitos as julgam importantes, mas não as utilizam. Por último, os achados da pesquisa revelaram que, dentre as ferramentas pesquisadas, apenas o uso do orçamento tem influenciado o desempenho das empresas objeto de estudo.

Transfer of Representations and Orbital Integrals for Inner Forms of GLn
Authors: Cohen Jonathan 
Published: May 2017

AbstractWe characterize the Local Langlands Correspondence (LLC) for inner forms of GLn via the Jacquet–Langlands Correspondence (JLC) and compatibility with the Langlands Classification. We show that LLC satisfies a natural compatibility with parabolic induction and characterize LLC for inner forms as a unique family of bijections Π(GLr(D)) → Φ(GLr(D)) for each r, (for a fixed D), satisfying certain properties. We construct a surjective map of Bernstein centers ℨ(GLn(F)) → ℨ(GLr(D)) and show this produces pairs of matching distributions in the sense of Haines. Finally, we construct explicit Iwahori-biinvariant matching functions for unit elements in the parahoric Hecke algebras of GLr(D), and thereby produce many explicit pairs of matching functions.

Abstract. The objective of this study was to evaluate the physicochemical characteristics of the longissimus muscle of lambs fed a control diet containing 3 % rapeseed oil (RO) (group I); an experimental diet with 2 % RO and 1 % fish oil (FO) (group II); or experimental diets with coupled addition of 2 % RO, 1 % FO, and 0.1 % carnosic acid (CA) (group III) without/with 0.35 ppm Se as selenized yeast (SeY) (group IV) or selenate (SeVI as sodium selenate, Na2SeO4) (group V). The results showed that dietary FO or SeVI affected the ultimate pH and meat color in comparison to lambs fed the control diet. The differences noted between diets in the case of muscle tissue were as follows: myosin HC (heavy chain) and LC1 (light chain), 150 kDa, α-actinin, 60 kDa, and TnT (troponin T), 30 kDa protein. The addition of FO to lamb diets resulted in a lower content of 30 kDa proteins, which are indicators of proteolysis. Considering the protein profile of drip loss, results showed effects of dietary administration of FO, CA, and Se (as SeY and SeVI) on the abundance of the following sarcoplasmic proteins: AMPDA (AMP deaminase), PGM (phosphoglucomutase), PK/PGI (pyruvate kinase/phosphoglucose isomerase), CK/PGAK (creatine kinase/phosphoglycerate kinase), ALD (aldolase), LDH (lactate dehydrogenase), PGAM (phosphoglycerate mutase), and TPI (triosephosphate isomerase). The lower content of TPI (in group II with comparison to groups III–V) and PGAM (in group II with comparison to group I and III) could be due to a higher ultimate pH in the group with FO addition, whereas lower contents of CK/PGAK, ALD, and LDH were attributed to Se addition. In comparison to the control diet, all experimental diets without SeVI decreased the content of the sum of all assayed amino acids ( ∑ AAs), indispensable amino acids ( ∑ IAAs), and dispensable amino acids ( ∑ DAAs) in the muscle. The highest ratios of  ∑ IAAs to  ∑ DAAs and  ∑ IAAs to  ∑ AAs were found in the muscle of lambs fed the diet containing RO, FO, and CA. The FO-supplemented diet with CA and SeVI increased the abundance of methionine in the muscle in comparison to the control diet and the FO-supplemented diet without/with CA.

Abstract. Advancing understanding of deep convection microphysics via mesoscale modeling studies of well-observed case studies requires observation-based aerosol inputs. Here, we derive hygroscopic aerosol size distribution input profiles from ground-based and airborne measurements for six convection case studies observed during the Midlatitude Continental Convective Cloud Experiment (MC3E) over Oklahoma. We demonstrate use of an input profile in simulations of the only well-observed case study that produced extensive stratiform outflow on 20 May 2011. At well-sampled elevations between −11 and −23 °C over widespread stratiform rain, ice crystal number concentrations are consistently dominated by a single mode near ∼ 400 µm in randomly oriented maximum dimension (Dmax). The ice mass at −23 °C is primarily in a closely collocated mode, whereas a mass mode near Dmax ∼ 1000 µm becomes dominant with decreasing elevation to the −11 °C level, consistent with possible aggregation during sedimentation. However, simulations with and without observation-based aerosol inputs systematically overpredict mass peak Dmax by a factor of 3–5 and underpredict ice number concentration by a factor of 4–10. Previously reported simulations with both two-moment and size-resolved microphysics have shown biases of a similar nature. The observed ice properties are notably similar to those reported from recent tropical measurements. Based on several lines of evidence, we speculate that updraft microphysical pathways determining outflow properties in the 20 May case are similar to a tropical regime, likely associated with warm-temperature ice multiplication that is not well understood or well represented in models.
Coastal ocean acidification and increasing total alkalinity in the northwestern Mediterranean Sea

Published: May 2017

Abstract. Coastal time series of ocean carbonate chemistry are critical for understanding how global anthropogenic change manifests in near-shore ecosystems. Yet, they are few and have low temporal resolution. At the time series station Point B in the northwestern Mediterranean Sea, seawater was sampled weekly from 2007 through 2015, at 1 and 50 m, and analyzed for total dissolved inorganic carbon (CT) and total alkalinity (AT). Parameters of the carbonate system such as pH (pHT, total hydrogen ion scale) were calculated and a deconvolution analysis was performed to identify drivers of change. The rate of surface ocean acidification was −0.0028 ± 0.0003 units pHT yr−1. This rate is larger than previously identified open-ocean trends due to rapid warming that occurred over the study period (0.072 ± 0.022 °C yr−1). The total pHT change over the study period was of similar magnitude as the diel pHT variability at this site. The acidification trend can be attributed to atmospheric carbon dioxide (CO2) forcing (59 %, 2.08 ± 0.01 ppm CO2 yr−1) and warming (41 %). Similar trends were observed at 50 m but rates were generally slower. At 1 m depth, the increase in atmospheric CO2 accounted for approximately 40 % of the observed increase in CT (2.97 ± 0.20 µmol kg−1 yr−1). The remaining increase in CT may have been driven by the same unidentified process that caused an increase in AT (2.08 ± 0.19 µmol kg−1 yr−1). Based on the analysis of monthly trends, synchronous increases in CT and AT were fastest in the spring–summer transition. The driving process of the interannual increase in AT has a seasonal and shallow component, which may indicate riverine or groundwater influence. This study exemplifies the importance of understanding changes in coastal carbonate chemistry through the lens of biogeochemical cycling at the land–sea interface. This is the first coastal acidification time series providing multiyear data at high temporal resolution. The data confirm rapid warming in the Mediterranean Sea and demonstrate coastal acidification with a synchronous increase in total alkalinity.

ABSTRACT This paper aims to measure the impact of the gradual adoption of Renewable Energy Sources (RES) on the welfare of consumers. To this end, we construct a theoretically founded measure of the true cost of living (TCL) and the equivalence scale (ES) for the household sector, based on a weather database of heating and cooling degree days. We estimate those values for 64 countries, which represent over two-thirds of the world population, according to World Bank statistics. We assume that the identified household in each country minimizes its expenditure on energy and other goods. We simulate alternate scenarios of renewables implementation in 2035, taking account of different RES prices, and assess the related societal implications of a gradual transition from fossil fuels to RES. The empirical results offer policymakers a basis for designing appropriate scenarios for the deployment of renewables, with the aim of fostering consumer welfare even in the context of international negotiations.

Procurando verificar o potencial, reprodutivo dos serradores, Oncideres impluviata (Germar, 1824) sobre angico: Parapiptadenia rigida (Benth.)(Leguminosae) e O. captiosa Martins, 1981 sobre canforeira: Cinnamomum camphora (L.) Nees et Ebern (Lauraceae) no período 1986/88, contou-se o número de incisões de posturas, por secção de 20 cm, por galho cortado, anotando-se o número de larvas desenvolvidas e adultos emergidos. O diâmetro dos galhos cortados foi medido a cada 20 cm, desde a base até o ápice. Verificou-se que O. impluviata corta galhos de maior diâmetro e realiza maior número de incisões em galhos de árvores isoladas em relação àquelas de dentro da mata. Emergem mais adultos dos galhos cortados dentro da mata do que naqueles de árvores isoladas. O número médio de incisões de postura de O. captiosa é maior do que aquele de O. impluviata, contudo o número médio de larvas desenvolvidas é aproximadamente 50% menor em O. captiosa que em O. impluviata.

Published: May 2017

Tomando-se por base um povoamento de Acacia mangium com 7 anos de idade, retirou-se discos ao longo do tronco de 126 árvores para o estudo da densidade básica da espécie. A densidade básica média (DBM) encontrada foi de 0,524 ± 0,076 g/cm3. A variação axial da densidade básica (Db), explicada por um modelo quadrático (R2 = 0,83), apresentou tendência de diminuição até a metade da altura do tronco, crescendo a partir daí até o topo, sem contudo atingir os valores da Db da base. O modelo linear foi o que melhor explicou a relação da DBM com a Db obtida a várias posições do tronco, mostrando-se mais acentuada (R2 = 0,81) a 25% da altura do tronco. Portanto, na determinação da DBM da espécie por métodos destrutivos, pode-se utilizar amostras retiradas à 25% da altura do tronco. No entanto, para amostragens não-destrutivas, a posição de 25% pode ser uma altura elevada e a retirada da amostra, por exemplo, utilizando um trado, pode-se tornar inviável. Nesse caso, sugere-se a retirada no DAP, pois relação, nesta posição também é alta (0,78).

Este trabalho teve como objetivo verificar se é viável, economicamente, implantar sistemas agro-silvo-pastoril com eucalipto (consórcio de eucalipto com arroz, soja e pastagens) em áreas de cerrado, visando a produzir madeira para serraria e para energia, bem como analisar o efeito que mudanças nos parâmetros taxa de desconto; valor da terra; preços da madeira, do boi gordo, do arroz e da soja; produtividades da madeira, do arroz e da soja; proporção da tora que é aproveitável para serraria e para energia; custos de produção provocam na viabilidade econômica do sistema. A área de estudo está situada no município de Paracatu, Minas Gerais. O método de avaliação econômica usado foi o Valor Presente Líquido. Os resultados encontrados permitiram concluir que implantar sistemas agro-silvo-pastoris com eucalipto em região de cerrado é uma opção viável economicamente, desde que, pelo menos, 5% da madeira produzida seja usada para serraria e a madeira restante seja usada para energia ou para outro fim que alcance valor igual ou mais alto no mercado. Algumas situações que podem fazer com que o sistema dê prejuízo são: taxas de desconto maiores que 11,45% ao ano; preço da terra acima de US$ 200.90 por hectare; produtividade do eucalipto inferior a 20,86 st/ha.ano; preço da arroba de boi menor que US$ 16.75; preço da madeira para serraria abaixo de US$ 5.24/st; preços do saco de soja e de arroz inferiores a US$ 6.34 e US$ 5.96 respectivamente; aumento de mais de 5,38%, simultaneamente, em todos os custos de produção.

O objetivo global do presente trabalho foi dar prosseguimento aos estudos sobre fragmentação do habitat na Cuesta de Botucatu (SP), em uma área de 18.422 ha. A pesquisa teve os seguintes objetivos específicos : 1) mapear os fragmentos de vegetação natural que ocorrem em uma área de estudo na Cuesta de Botucatu (SP), valendo-se de imagens multiespectrais TM do satélite Landsat-5 tomadas em dois períodos (1986 e 1993); 2) avaliar a estabilidade da fragmentação do habitat, com o auxílio de um sistema de informações geográficas (SIG), comparando os mapas temáticos de ocorrência de vegetação natural de 1986 e 1993; 3) descrever os padrões da fragmentação da vegetação natural na depressão periférica da Cuesta de Botucatu (SP). A análise dos dados espaciais de 1986 e 1993 revelou que o fenômeno de fragmentação da vegetação natural é instável. O processo apresenta distinção de escala: 1) o subconjunto de fragmentos maiores não é fractal, levando à observação de que as manchas de vegetação dessa classe não se dividem, simplesmente diminuem de tamanho obedecendo a uma tendência linear; 2) o subconjunto de fragmentos de tamanhos intermediários foi detectado como não sendo fractal, levando à observação de que, no processo de fragmentação, as manchas de vegetação dessa classe não se dividem, simplesmente diminuem de tamanho, obedecendo a uma progressão geométrica crescente; 3) o subconjunto de dados relativos aos fragmentos de menor tamanho é fractal, permitindo afirmar que o processo de fragmentação relacionado a esse grupo ocorre com uma divisão dos fragmentos que obedece a uma progressão geométrica uniforme.

Published: May 2017

AimAtorvastatin is a HMG-CoA reductase inhibitor used for hyperlipidemia. Atorvastatin is generally safe but may induce cholestasis. The present study aimed to examine the effects of atorvastatin on hepatic gene expression related to bile acid metabolism and homeostasis, as well as the expression of circadian clock genes in livers of mice.MethodsAdult male mice were given atorvastatin (10, 30, and 100 mg/kg, po) daily for 30 days, and blood biochemistry, histopathology, and gene expression were examined.ResultsRepeated administration of atorvastatin did not affect animal body weight gain or liver weights. Serum enzyme activities were in the normal range. Histologically, the high dose of atorvastatin produced scattered swollen hepatocytes, foci of feathery-like degeneration, together with increased expression of Egr-1 and metallothionein-1. Atorvastatin increased the expression of Cyp7a1 in the liver, along with FXR and SHP. In contract, atorvastatin decreased the expression of bile acid transporters Ntcp, Bsep, Ostα, and Ostβ. The most dramatic change was the 30-fold induction of Cyp7a1. Because Cyp7a1 is a circadian clock-controlled gene, we further examined the effect of atorvastatin on clock gene expression. Atorvastatin increased the expression of clock core master genes Bmal1 and Npas2, decreased the expression of clock feedback genes Per2, Per3, and the clock targeted genes Dbp and Tef, whereas it had no effect on Cry1 and Nr1d1 expression.ConclusionRepeated administration of atorvastatin affects bile acid metabolism and markedly increases the expression of the bile acid synthesis rate-limiting enzyme gene Cyp7a1, together with alterations in the expression of circadian clock genes.
