Analysis of time-lapse data error in complex conductivity imaging to alleviate anthropogenic noise for site characterization
Authors: Flores Orozco Adrian , Kemna Andreas , Binley Andrew , Cassiani Giorgio 
Published: December 2018

Previous studies have demonstrated the potential benefits of the complex conductivity (CC) imaging over electrical resistivity tomography for an improved delineation of hydrocarbon-impacted sites and accompanying biogeochemical processes. However, time-lapse CC field applications are still rare, in particular for measurements performed near anthropogenic structures such as buried pipes or tanks, which are typically present at contaminated sites. To fill this gap, we have developed CC imaging (CCI) results for monitoring data collected in Trecate (northwest Italy), a site impacted by a crude oil spill. Initial imaging results reveal only a poor correlation with seasonal variations of the groundwater table at the site (approximately 6 m). However, it is not clear to which extend such results are affected by anthropogenic structures present at the site. To address this, we performed a detailed analysis of the misfit between direct and reciprocal time-lapse differences. Based on this analysis, we were able to discriminate spatial and temporal sources of systematic errors, with the latter commonly affecting measurements collected near anthropogenic structures. Following our approach, CC images reveal that temporal changes in the electrical properties correlate well with seasonal fluctuations in the groundwater level for areas free of contaminants, whereas contaminated areas exhibit a constant response over time characterized by a relatively high electrical conductivity and a negligible polarization effect. In accordance with a recent mechanistic model, such a response can be explained by the presence of immiscible fluids (oil and air) forming a continuous film through the micro and macropores, hindering the development of ion-selective membranes and membrane polarization. Our results demonstrate the applicability of CCI for an improved characterization of hydrocarbon-contaminated areas, even in areas affected by cultural noise.
Resistência negra pós-abolição no Norte do Brasil: a capoeira e o boi-bumbá
Authors: Leal Luiz Augusto Pinheiro 
Published: December 2018

Este artigo trata de duas práticas culturais afro-brasileiras perseguidas no contexto pós-abolição: a capoeira e o boi-bumbá. Elas foram os principais instrumentos de mobilização e luta de indivíduos e coletividades negras frente ao processo de embranquecimento físico e cultural no Norte do Brasil. A primeira em sua dimensão de defesa corporal negra. A segunda como elemento que articulava saberes, identidades e ludicidade afro em espaços públicos. Através delas, homens e mulheres negros se faziam presentes nas ruas e praças através de práticas culturais que afirmavam identidades ancestrais. Ao mesmo tempo, causavam desconforto a uma sociedade que queria ser reconhecida como herdeira direta do mundo ocidental. Palavras-chave: Abolição; Capoeira; Boi-bumbá; Pará

Apresentação do Volume 10 Número 20 da Revista Brasileira de História & Ciências Sociais A Revista Brasileira de História & Ciências Sociais – RBHCS – tem a imensa satisfação de trazer ao público acadêmico sua nova edição. A edição número 20 da RBHCS apresenta continuidade temático com o dossiê anterior intitulado “Protagonismos indígenas em diferentes tempos e espaços: diálogos entre História & Ciências Sociais” igualmente organizado pelo Prof. Dr. Giovani José da Silva (UNIFAP) e a Profª. Drª. Izabel Missagia de Mattos (UFRRJ). No presente volume titulado “Protagonismos indígenas: diálogos entre História & Ciências Sociais em diferentes tempos e espaços contemporâneos”, são discutidos temas referente ao protagonismo indígena em diferentes espaços do território nacional e mesmo internacional no período mais recente de nossa história. Dentre os assuntos tratados, o movimento indígena frente a Constituinte de 1988 e as discussões em torno das leis indigenistas foram recorrentes, matérias de suma importância para a agenda de antropólogos, sociólogos, historiadores e mesmo pesquisadores de outras áreas. É significativa a imagem reproduzida na capa desta edição em que lideranças indígenas se fizeram presentes durante as discussões e negociações referente ao capítulo dos índios na Constituinte de 1988[1]. Muito embora já estejamos ultrapassando os 30 anos de nossa Carta Magna, a imagem se mantém viva, a luta por cidadania e direitos dos povos tradicionais é uma constante. Em nosso presente, ainda com novos desafios, visto os rumos políticos que nos aguardam nos próximos anos, há a tendência a invisibilização e desarticulação das políticas de proteção aos povos indígenas já estabelecidas. Nesse sentido, os dois volumes de 2018 da RBHCS, além de excelentes resultados de pesquisa, são um material rico para reflexão e discussão sobre os protagonismos indígenas no passado e no presente, bagagem indispensável para os desafios na contemporaneidade. Além do dossiê, a atual edição apresenta também a sessão de temática livre com cinco artigos na área da História e da Ciência Política e uma resenha. Frente a essa diversidade, a presente edição atinge a meta de nosso escopo editorial, mantendo-se um periódico multidisciplinar, que busca fomentar o diálogo às diversas áreas do conhecimento com base na teoria social. A todos e todas desejamos uma boa leitura! Verão de 2018 Editores da RBHCS Profa.

Published: December 2018

Os usos de técnicas de análise espacial, as chamadas geotecnologias, vêm contribuindo significativamente para o monitoramento, mapeamento e fiscalização das mudanças ocorridas na superfície terrestre. Entre as diversas possibilidades de uso dessas técnicas, destacam-se aquelas voltadas à análise e interpretação da paisagem e sua dinâmica, fornecendo importantes elementos à compreensão da realidade socioespacial no qual está inserida e, para, além disso, como tais processos, sobretudo antrópicos, interagem com o ambiente natural, formando padrões específicos de uso da terra. Nesse contexto, o presente trabalho tem por objetivo central analisar o emprego de geotecnologias no reconhecimento de padrões de uso e ocupação da terra a partir da escala da paisagem em uma área situada no município de Belterra, estado do Pará. Para tanto, emprega-se de forma integrada técnicas de processamento digital de imagem, com dados cartográficos e trabalho de campo. O produto gerado, a partir de uma cena Landsat TM-5, das bandas 5, 4 e 3, consistiu num mapa dos diferentes tipos de uso e cobertura da terra, os quais foram organizados em dois grandes grupos: unidades de paisagem natural e unidades de paisagem antropizadas. O que permitiu observar a distribuição espacial e a área ocupada pelas diferentes unidades detectadas, bem como avaliar a dinâmica espacial de produção e modificação da paisagem. Como suporte à análise espacial, o uso das técnicas empregadas mostrou-se de grande aplicabilidade na delimitação e caracterização de unidades de paisagem, consideradas atualmente importantes categorias de análise espacial no âmbito do planejamento e da gestão territorial.

Authors: Bond Bailey Madison , Glickfield R. Alexander , Herr John E. 
Published: December 2018

Abstract
We use a theorem of Lam and Leung to prove that a submatrix of a Fourier matrix cannot be Hadamard for particular cases when the dimension of the submatrix does not divide the dimension of the Fourier matrix. We also make some observations on the trace-spectrum relationship of dephased Hadamard matrices of low dimension.

Abstract
Availability of nutrients in soil plays an important role in the productivity and quality of flowers in chrysanthemum. A set of novel biofilm inoculants- Anabaena-Azotobacter, Anabaena-Pseudomonas fluorescens (An-Psf) and Anabaena-Trichoderma (An-Tr) were applied as carrier based dry formulation or soil drench and their performance compared in two varieties of chrysanthemum (White Star and Zembla), in a climate-controlled greenhouse. Both the An-Psf and (An-Tr) inoculants enhanced glomalin related soil proteins in the rhizosphere of White Star, while in terms of polysaccharide content of soil, both these inoculants performed better in Zembla variety. Significant increases in the availability of selected macro and micronutrients in rhizosphere soil samples, in both chrysanthemum varieties were recorded, particularly when the inoculants were applied as soil drench. Principal Component analysis illustrated the significant interaction among soil and plant parameters, more specifically, the distinct effect of the inoculants, as compared to the application of carrier alone or control treatment. This investigation demonstrated the varietal effects on soil biological activities and significance of mode of application of microbial inoculants in influencing plant growth and rhizospheric metabolic activities.
Optimal design of the flywheel using nature inspired optimization algorithms
Authors: Singh Prem , Chaudhary Himanshu 
Published: December 2018

Abstract
This paper presents the optimal design procedure of a flywheel using a cubic B-spline curve. The flywheel plays a vital role in storing kinetic energy in modern machines. The kinetic energy evaluates the performance of the flywheel. In order to improve the kinetic energy of a flywheel, a shape optimization model of the flywheel, with maximization of kinetic energy, is formulated using a cubic spline curve under the constraints of the mass of flywheel, and the maximum value of Von Mises stresses at all points along the radial direction. The Von Mises stresses at all points are determined using the two-point boundary value differential equation. The control points of the cubic B-spline curve are taken as design variables. Then the formulated problem is solved using particle swarm algorithm (PSO), genetic algorithm (GA), and Jaya algorithm. The proposed approach is applied to the flywheel of an agricultural thresher machine. It is found that the Jaya algorithm gives better results compared to the other algorithms. The optimized shape of the flywheel is simulated using MSC ADAMS software.

Selective serotonin (5-HT) reuptake inhibitors (SSRIs) are first-line antidepressants but require several weeks to elicit their actions. Chronic SSRI treatment induces desensitization of 5-HT1A autoreceptors to enhance 5-HT neurotransmission. Mice (both sexes) with gene deletion of 5-HT1A autoreceptors in adult 5-HT neurons (1AcKO) were tested for response to SSRIs. Tamoxifen-induced recombination in adult1AcKOmice specifically reduced 5-HT1A autoreceptor levels. The1AcKOmice showed a loss of 5-HT1A autoreceptor-mediated hypothermia and electrophysiological responses, but no changes in anxiety- or depression-like behavior. Subchronic fluoxetine (FLX) treatment induced an unexpected anxiogenic effect in1AcKOmice in the novelty suppressed feeding and elevated plus maze tests, as did escitalopram in the novelty suppressed feeding test. No effect was seen in wild-type (WT) mice. Subchronic FLX increased 5-HT metabolism in prefrontal cortex, hippocampus, and raphe of1AcKObut notWTmice, suggesting hyperactivation of 5-HT release. To detect chronic cellular activation, FosB+cells were quantified. FosB+cells were reduced in entorhinal cortex and hippocampus (CA2/3) and increased in dorsal raphe 5-HT cells of1AcKOmice, suggesting increased raphe activation. InWTbut not1AcKOmice, FLX reduced FosB+cells in the median raphe, hippocampus, entorhinal cortex, and median septum, which receive rich 5-HT projections. Thus, in the absence of 5-HT1A autoreceptors, SSRIs induce a paradoxical anxiogenic response. This may involve imbalance in activation of dorsal and median raphe to regulate septohippocampal or fimbria-fornix pathways. These results suggest that markedly reduced 5-HT1A autoreceptors may provide a marker for aberrant response to SSRI treatment.SIGNIFICANCE STATEMENTSerotonin-selective reuptake inhibitors (SSRIs) are effective in treating anxiety and depression in humans and mouse models. However, in some cases, SSRIs can increase anxiety, but the mechanisms involved are unclear. Here we show that, rather than enhancing SSRI benefits, adulthood knockout (KO) of the 5-HT1A autoreceptor, a critical negative regulator of 5-HT activity, results in an SSRI-induced anxiety effect that appears to involve a hyperactivation of the 5-HT system in certain brain areas. Thus, subjects with very low levels of 5-HT1A autoreceptors, such as during childhood or adolescence, may be at risk for an SSRI-induced anxiety response.

Haftung von Rating-Agenturen gegenüber Anlegern: Haftungshürden in der deutschen Gerichtspraxis
Authors: Schroeter Ulrich G. 
Published: December 2018

Zusammenfassung
Die Haftung von Rating-Agenturen gegenüber Anlegern, die auf veröffentlichte Ratings vertraut haben, und ihre möglichen Rechtsgrundlagen gehören zu den vielfach diskutierten Problemfeldern des jüngeren Finanzmarktrechts. Die EU verlieh der Diskussion im Jahre 2013 neue Impulse, als sie mit Art. 35a EU-RatingVO erstmals eine ratingspezifische unionsrechtliche Haftungsnorm schuf. Seit Kurzem liegen nunmehr erste Urteile deutscher Instanzgerichte vor, welche die Ratinghaftung auf Grundlage des EU-Rechts wie auch des deutschen Rechts behandeln. Der vorliegende Beitrag erläutert die sich entwickelnde Rechtsprechungspraxis und diskutiert die zentralen Hürden, die darin für eine Haftung von Rating-Agenturen deutlich werden.
Der Verbrauchergerichtsstand bei Kapitalanlagegeschäften
Authors: Kainer Friedemann 
Published: December 2018

Zusammenfassung
Die Verwaltung privaten Vermögens gilt nach der ganz überwiegenden Auffassung in der Rechtsprechung und Literatur als Verbrauchergeschäft. Gilt dies in jedem Fall? Auch bei hochkomplexen und risikoreichen Anlagen? Der Beitrag untersucht diese Frage mit Blick auf die neuere Entwicklung zu einem auch die Empfängersicht berücksichtigenden Verbraucherbegriff und entwickelt am Maßstab des Art. 17 Brüssel Ia-VO eine differenzierende Auffassung für den Verbrauchergerichtsstand. Insbesondere häufige und komplexe Anlagegeschäfte, soweit sie aus Empfängersicht eine Professionalisierung erfordern, sind demnach nicht als Verbrauchergeschäfte zu qualifizieren.

Das ToTV-Kriterium der MiFID II in der Rechtspraxis
Authors: Hoops Christian 
Published: December 2018

Zusammenfassung
Mit der zweiten Finanzmarktrichtlinie (Markets in Financial Instruments Directive – MiFID II) und der sie begleitenden Verordnung (Markets in Financial Instruments Regulation – MiFIR) soll u. a. gewährleistet werden, dass der gesamte organisierte Handel an regulierten Handelsplätzen stattfinden und sowohl in der Vorhandels- als auch in der Nachhandelsphase vollkommen transparent sein sollte. Die Transparenzpflichten der ersten Finanzmarktrichtlinie (MiFID I) waren nicht auf alle Finanzinstrumente und Formen des organisierten Handels anwendbar, so dass ein Großteil des Wertpapierhandels intransparent durchgeführt wurde. Im Rahmen der MiFID II wurden daher das Marktinfrastrukturregime sowie die Melde- und Transparenzpflichten überarbeitet. Anders als in der Vergangenheit sind diese Pflichten nun bereits anwendbar, wenn ein Finanzinstrument an einem Handelsplatz gehandelt wird (traded on a trading venue – ToTV). Eine trennscharfe Differenzierung, ab wann ein Finanzinstrument das ToTV-Kriterium erfüllt, ist in der Rechtspraxis allerdings mit Herausforderungen verbunden und es besteht Verunsicherung darüber, ob die Anforderungen der MiFID II-Gesetzgebung korrekt umgesetzt werden.

Microorganisms are of particular interest because of their ability to synthesize high-value secondary compounds and provide us with novel and diverse chemical structures. The most common source of antibiotics is Actinomycetes which provide around two-third of naturally occurring antibiotics, including many of medical importance. In this study, 81 strains of actinomycetes were isolated from 145 samples including: sediments, sponges, soft corals, echinoderms and starfish collected from three sea areas of Vietnam: Hue, Da Nang and Quang Nam. The strains were fermented in A+ medium and fermentation broths were extracted 5 times with ethyl acetate. The extracts were evaporated under reduced pressure to yield crude extracts. Quantitative assay was used to determine MIC (Minimum inhibitory concentration) of extract against 7 reference strains. From the results of screening, Seven strains of actinomycetes that have the highest biological activity (Code: G244, G246, G261, G266, G278, G280 and G290) were chosen to be identified by morphological and phylogenetic based on 16S rRNA gene sequences. The results showed that 6 strains G246, G261, G266, G278, G280 and G290 belonged to the genus Streptomyces; and the strain G244 belonged to the genus Micromonospora. In particular, strains G244, G278, G280 were resistant 5/7 strains of microorganisms test, with values MICs from 2 µg/mL to 256 µg/mL; and three strains G261, G266, G290 showed the inhibitory effect towards 4/7 strains of microorganisms test, with respective values MICs from 2 µg/mL to 256 µg/mL. Moreover, six of the seven selected strains were highly resistant to yeast Candida albicans ATCC10231 with MIC values from 2 µg/mL to 256 µg/mL. These results indicated that marine Actinomycetes in Vietnam are also a potential source to find bioactive substances.
