Abstract On November 2015, one of Brazil's most important watersheds was impacted by the mine waste from Fundão dam collapse in Mariana. The mine waste traveled over 600 km along the Doce River before reaching the sea, causing severe devastation along its way. Here we assessed trace element concentrations and cytogenotoxic effects of the released mine waste. Water samples were collected along the Doce River ten days after the disaster in two impacted sites and one non-impacted site. Sampling points were located hundreds of kilometers downstream of the collapsed dam. Water samples were used for trace element quantification and to run an experiment using Allium cepa to test cytogenotoxicity. We found extremely high concentrations of particulate Fe, Al, and Mn in the impacted sites. We observed cytogenotoxic effects such as alterations in mitotic and phase indexes, and enhanced frequency of chromosomal aberrations. Our results indicate interferences in the cell cycle in impacted sites located hundreds of kilometers downstream of the disaster. The environmental impacts of the dam collapse may not only be far-reaching but also very likely long-lasting, because the mine waste may persist in the Doce River sediment for decades. Highlights • Higher concentrations of particulate metals were found in impacted sites. • Cytogenotoxic effects were found in the impacted sites. • Mining waste affected genetic aspects of Allium cepa. • Impacts of the tragedy are far-reaching and long-lasting.

In 2015, a major technological disaster occurred in Brazil: The breakdown of a dam in the city of Mariana. When discharged along the Rio Doce basin, the ore debris have generated negative externalities that affected two states: Minas Gerais and Espírito Santo. The objective of this work is to evaluate the impact of the disaster on the economic performance of these States. To this end, synthetic controls were constructed to identify the behavior of the States in the absence of the disaster. In terms of the general manufacturing production, Espírito Santo State had a reduction in 18.22% in comparison with the situation before the disaster, whereas there was no significant impact in Minas Gerais. As for the extractive mineral manufacturing production, both states showed significant decrease of this index as a result of the disaster: Espírito Santo state had a reduction in 25,01%, whereas Minas Gerais exhibited a decrease in 15,58%.

IODP Expedition 352 drilled four sites in the Bonin outer forearc, providing a detailed record of lava eruption and dike emplacement during a short-lived (<2 Ma) seafloor spreading event that took place immediately after the initiation of Pacific Plate subduction at c. 52.5 Ma. This spreading produced up to 120 km of oceanic lithosphere with a structure analogous to that of a supra-subduction zone ophiolite. Two groups of sites were drilled: Sites U1440 and U1441 are oldest and nearest to the trench and principally recovered forearc basalt (FAB); Sites U1439 and U1442 are younger and farther from the trench and recovered boninites. Holes 1440B and 1439C are both rooted in dike complexes, confirming a likely seafloor spreading origin for most of the drilled crust. Geochemical evidence points to the shoaling of a mantle plume beneath a Mesozoic ridge and basin terrane as a likely trigger for the Pacific plate to begin to subduct beneath that terrane. The timing and nature of the collision between the Indian and Asian continents allows it also to have played a role in triggering this event. Seafloor spreading began due to extension related to slab rollback immediately following the start of subduction. Mantle entering this new extensional régime was highly depleted both by melting and by incorporation of ancient, depleted mantle associated with the plume. Initially, slab-derived aqueous fluids made negligible to small contributions to the mantle source, which then underwent decompression melting producing oceanic crust with a FAB composition that resembles the most incompatible element-depleted basalts in present-day seafloor spreading settings. The same, or a renewed, ridge system produced low-Si boninite (LSB) magmas once hydrous melts from the subducting Pacific oceanic crust fluxed the now highly depleted, but still hot, mantle. High-Si boninite (HSB) volcanism began at c. 51.3 Ma, about the time when seafloor spreading slowed and more focused volcanism began in response to increased subduction relative to slab rollback. The subsequent history of the drilled area was marked by several kilometers of uplift and erosion, perhaps related to serpentinization of its depleted mantle foundation, followed by extension to produce small sedimentary basins.

59. El Principio de Consentimiento en la Actualidad: Cómo el Principado de Liechtenstein Reivindica las Tesis de Juan de Mariana sobre el Gobierno

Benjamín Gonzalo, Marcos and Benjamín Gonzalo, Marcos
- Abstract
Well-known are the contributions to social and legal sciences made by the Spanish scholastics. Specifically, in regard to political science, their ideas against the rampant absolutism of the time stand out, for they vehemently defended that society and its institutions –specially the institution of private property–existed previously to the State. Noteworthy are the ideas of Jesuit Juan de Mariana about the adequate functions of Government as well as their wide limitations, always contingent in their mandates to their subjects’ consent (the “principle of consent”). Not only was Father Juan de Mariana ahead of the principles of American constitutionalism, he gave one step further, defending that the overthrow of the governor had he exceeded his functions. The following paper defends that, far from being an anachronistic theory of Government, the ideas defended by the Jesuit are currently claimed by the Principality of Liechtenstein and the political philosophy of the Reigning Prince, Hans-Adam II., Son conocidas las aportaciones de la escolástica española a las ciencias sociales y jurídicas. Concretamente, en lo que a la ciencia política se refiere, destacan sus ideas contrarias al absolutismo rampante de la época, defendiendo vehementemente la sociedad y sus instituciones –especialmente la institución de la propiedad privada–como previas al Estado. Destacan en este ámbito las ideas del jesuita Juan de Mariana sobre las funciones adecuadas del Gobierno y sus amplias limitaciones, estando siempre supeditado en sus mandatos al consentimiento de los súbditos (el «principio de consentimiento»). El padre Juan de Mariana no sólo se adelantó a los principios del constitucionalismo americano, sino que dio un paso más, llegando a defender la deposición del gobernante si este excediera sus funciones. En el siguiente artículo se defenderá que, lejos de tratarse de una teoría anacrónica sobre el Gobierno, las ideas defendidas por el jesuita se ven reivindicadas en la actualidad por el Principado de Liechtenstein y la filosofía política del Príncipe Reinante, Hans-Adam II.

Prieto López, Leopoldo and Prieto López, Leopoldo
- Abstract
This article aims to investigate the exchange of ideas between William Prynne and the Hispanic scholastic tradition, especially in relation to the origin and limits of the king's power as essentially subordinate to Parliament. Prynne's Calvinist theology, strongly opposed to Catholic and Arminian-Anglican theology, is also considered at the beginning of the work. The work ends by concluding that in Prynne’s thought there is, along with a radical theological opposition to Arminians and Catholics, an intense reception of the political ideas of Salamonio, the schoolmen and the doctors of Salamancha, such as Mariana, Suárez, etc., largely coinciding with the sources of medieval English political law, such as Bracton, Fleta and Fortescue. From a methodological point of view, the article has been elaborated from an intense work of Prynne's theological and political primary sources, accessible thanks to the EEBO (Early English Books Online) database of the University of Michigan., El presente artículo se propone indagar en el comercio de ideas entre William Prynne y la tradición escolástica hispánica, especialmente en lo relativo al origen y límites del poder del rey en cuanto esencialmente subordinado al Parlamento. También se considera al inicio del trabajo la teología calvinista de Prynne, fuertemente enfrentada a la teología católica y arminiano-anglicana. El trabajo termina concluyendo que en el pensamiento de Prynne se da, junto a una radical oposición teológica a arminianos y católicos, una intensa recepción de las ideas políticas de Salamonio, los schoolmen y los doctors of Salamancha, tales como Mariana, Suárez, etc., coincidentes en buena medida con las fuentes del Derecho político medieval inglés, tales como Bracton, Fleta y Fortescue. Desde un punto de vista metodológico el artículo ha sido elaborado a partir de un intenso trabajo de fuentes primarias teológicas y políticas de Prynne, accesibles gracias a la base de datos EEBO (Early English Books Online), de la Universidad de Michigan.

In 2015, the Fundão dam of the company Samarco (controlled by Vale) collapsed, causing a huge wave of mud, causing 19 deaths and becoming the biggest environmental disaster in Brazil. As early as 2019, a new dam rupture took place, with Vale as the responsible company, with around 270 fatalities. Both disasters brought numerous social, environmental and financial problems. This study aims to analyze the impact of environmental disaster of Brumadinho and Mariana on Vale and Samarco Financial Statements, specifically the problems related to provisions, contingencies and environmental processes. The method employed with the case study was a content analysis, and data collection was carried out from Financial Statements, Reference Form and the company’s press channel over a 10-year period from 2010 to 2019. Among the main results, we observed that in 2015, the Mariana dam collapse may explain the significant increase in the coming years regarding deposits and provisions for environmental actions filed against Samarco and Vale. In 2019, it is observed that the amount moved to judicial deposits increased 45 times compared to the previous year. Considering this fact, there is a need for studies that contribute to the transparency of actions for the victims, communities affected by the tragedy, disregard of those involved and the environment, since this is not the first disaster caused by this company. RESUMO Em 2015, ocorreu o rompimento da barragem de Fundão da empresa Samarco (controlada pela Vale), causando uma enorme onda de lama, causando 19 mortes e tornando-se o maior desastre ambiental do Brasil. Logo em 2019, um novo rompimento de barragem aconteceu, tendo como empresa responsável a Vale, tendo em torno de 270 vítimas fatais. Ambos os desastres trouxeram inúmeros problemas socioambientais e financeiros. O estudo tem como objetivo analisar o impacto do desastre ambiental de Brumadinho e Mariana nas Demonstrações Financeiras da Vale e Samarco, especificamente os problemas relacionados às provisões, contingências e processos ambientais. O método empregado no estudo de caso foi a análise de conteúdo e, a coleta de dados foi realizada a partir das Demonstrações Financeiras, Formulários de Referência e "press release" da empresa num período de 10 anos compreendido entre 2010 a 2019. Entre os principais resultados, observamos que em 2015, o colapso da barragem de Mariana pode explicar o aumento significativo de depósitos e provisões para ações ambientais movidas contra a Samarco e a Vale nos anos seguintes. Em 2019, detectou-se que o valor transferido para depósitos judiciais aumentou 45 vezes em relação ao ano anterior. Considerando esse fato, são necessários estudos que contribuam para a transparência das ações das vítimas, comunidades afetadas, desrespeito aos envolvidos e ao meio ambiente, pois esse não é o primeiro desastre causado pela empresa. RESUMEN En 2015, la represa Fundão de la empresa Samarco (controlada por Vale) se derrumbó, provocando una gran ola de lodo, provocando 19 muertos y convirtiéndose en el mayor desastre ambiental de Brasil. Ya en 2019, se produjo una nueva ruptura de presa, con Vale como empresa responsable, con alrededor de 270 muertes. Ambos desastres trajeron numerosos problemas sociales, ambientales y financieros. Este estudio tiene como objetivo analizar el impacto del desastre ambiental de Brumadinho y Mariana en los estados financieros de Vale y Samarco, específicamente los problemas relacionados con provisiones, contingencias y procesos ambientales. El método utilizado en el estudio de caso fue el análisis de contenido y la recopilación de datos se realizó mediante los estados financieros, formularios de referencia y comunicados de prensa de la compañía durante un período de 10 años de 2010 a 2019. Entre los principales resultados, observamos que en 2015, el colapso de la presa Mariana puede explicar el aumento significativo de depósitos y provisiones para acciones ambientales presentadas contra Samarco y Vale en los años siguientes. En 2019, se descubrió que el monto transferido a depósitos judiciales aumentó 45 veces en relación con el año anterior. Teniendo en cuenta este hecho, se necesitan estudios que contribuyan a la transparencia de las acciones de las víctimas, las comunidades afectadas, la falta de respeto por los involucrados y el medio ambiente, ya que este no es el primer desastre causado por la empresa.

A cobertura ambiental brasileira, de forma geral, tem sido marcada por uma falta de aprofundamento e contextualização sobre os fenômenos que abrangem as grandes questões dessa editoria na atualidade, tais como: agressivo desmatamento e grilagem de terras nos principais biomas brasileiros, a saber, floresta amazônica e Pantanal; avanço da fronteira agrícola em direção a esses espaços geográficos de forma descontrolada, ocupando-os sob a forma de monocultura da soja e pastagens; aquecimento global e mudanças climáticas, em decorrência do aniquilamento dos sistemas de vegetação nativa; cobertura sensacionalista de fenômenos climáticos; contaminação dos recursos hídricos, até mesmo dos grandes sistemas Aquífero Guarani e Sistema Amazônico; falta de formação específica dos profissionais que cobrem a pauta de meio ambiente, com a consequente cobertura não aprofundada dos fatos, entre outros fatores. Para analisar o contexto da cobertura ambiental, entrevistamos a jornalista Adriana Menezes, que toma como exemplo o desastre ambiental ocorrido em Mariana, Minas Gerais, em novembro de 2015. Brazilian environmental coverage, in general, has been marked by a lack of depth and contextualization about the phenomena that cover the major issues of this editorial today, such as: aggressive deforestation and land grabbing in the main Brazilian biomes, namely , Amazon rainforest and Pantanal; advance of the agricultural frontier towards these geographic spaces in an uncontrolled way, occupying them in the form of soybean monoculture and pastures; global warming and climate change, as a result of the annihilation of native vegetation systems; sensationalist coverage of weather phenomena; contamination of water resources, even the great Guarani Aquifer and Amazon System systems; lack of specific training for professionals who cover the May Ambiente agenda, with the consequent lack of in-depth coverage of the facts, among other factors. To analyze the context of environmental coverage, we interviewed journalist Adriana Menezes, who takes as an example the environmental disaster that occurred in Mariana, Minas Gerais, in November 2015.

On November 5, 2015, after the collapse of the Fundão tailings dam, a massive amount of iron mine waste was released into the Doce River system in southeast Brazil. The aim of our study was to determine the mass fractions of potentially toxic elements in soil affected by the deposition of material by the waste wave. A preliminary screening was performed with portable X-ray fluorescence spectrometry (PXRF) and principal component analysis (PCA). The EPA 3050B method was further applied to digest the samples for quantitative determination of As, Ba, Cr, Cu, Mn, Ni, Pb, V, and Zn by inductively coupled plasma mass spectrometry. PCA was useful to classify the mine waste samples based on the Fe signal from the PXRF spectra, in spite of the heterogeneous nature of the material discharged into the Doce River system. The anomalous levels of As (up to 164 mg kg) and Mn (as high as 2410 mg kg) found in some mine waste and affected soil samples are within the background ranges typically observed in the soils of the Iron Quadrangle region. The toxicity characteristic leaching procedure shows no evidence of hazards regarding As, but a high natural background level of Mn was found in the mobile fraction. This preliminary environmental assessment highlights the importance of evaluation of long-term effects on soil directly impacted, as well as on the aquatic biota of the Doce River system and adjacent coastal environment given the large affected area, which includes regions with varying background levels of toxic elements.

- Abstract
In this work, eight testimonies of the survivors from the rupture of the Samarco Mining dam in Bento Rodrigues (Mariana - MG) were analyzed. There are four women and four men who have experienced the consequences of losing their homes, loved ones, property, land, etc. For this, one makes use of phenomenology and the phenomenological method. To understand phenomenology, it is necessary to understand that man is a "giver of meaning" to the world. Therefore, its method focuses on man, specifically on the meaning analysis and relevance of human experience, seeking to capture the essences of what the man has experienced. The testimonies were collected in places wherein the residents were housed in the days subsequent to the dam rupture. It is intended to understand the event from the person who experienced it, for this reason, the testimonies collection in the days subsequent the disaster. [ABSTRACT FROM AUTHOR]

Uno de los mitos clásicos que aparecen en la novela intercalada cervantina, El curioso impertinente, el del rapto de Dánae, no ha recibido mucha atención crítica. Las muchas imágenes visuales de la novela cervantina recuerdan la écfrasis de este mito en el Eunuco de Terencio, donde la pintura es una de las causas del rapto de Pánfila. La novela cervantina se hace eco de la controversia que había suscitado el Eunuco, comenzando con San Agustín; controversia que continuó hasta el Siglo de Oro con escritores tales como Juan de Mariana y Juan de Pineda. El estudio de la comedia de Terencio y de la pintura de Dánae enviada por Tiziano a Felipe II ayudan a comprender la importancia del mito como elemento temático y estructural en la novela. La historia de Dánae en Cervantes forma parte del debate sobre el impacto de las artes visuales en la época de la Contrarreforma.

International audience; Les fouilles préventives récentes réalisées par l’INRAP en Corse ont livré un important corpus de structures liées à la pratique de la crémation. Ces dernières n’étaient, jusqu’alors connues que grâce aux fouilles réalisées par G. Morrachini-Mazel dans les années 70, et aucune étude exhaustive n’avait pu être conduite. La multiplicité des ensembles funéraires appréhendés ces cinq dernières années sur les communes d’Aléria et de Lucciana offrent ainsi des données inédites permettant aujourd’hui de dresser un premier bilan des gestes et des pratiques en usage en Corse durant l’Antiquité.La crémation n’a jamais constitué le traitement du corps majoritairement choisi par les populations corses, à la différence du sud-est de la Gaule ou encore de l’Italie, qui, dans des phases chronologiques bien particulières l’ont massivement adoptée. Elle demeure cependant largement attestée depuis les hautes périodes mais témoigne d’un geste apporté par les civilisations méditerranéennes exogènes (grecque, et étrusco-italique). En effet, les pratiques funéraires indigènes locales de l’âge du Fer renseignent des dépôts sous abri pour l’essentiel. Ce n’est qu’avec l’arrivée des Étrusques qu'apparaît d’abord timidement la pratique crématoire : les fouilles anciennes des zones funéraires d’Aléria conduites par J. Jehasse indiquent une présence ponctuelle entre les années 500 et 325 BC. Sous la domination étrusco-italique entre 300 et 150 BC, ce mode de traitement connaît un meilleur engouement sans pour autant devenir exclusif. Ce n’est qu’au cours du Haut Empire que les structures funéraires sont les plus nombreuses. À Aléria, dont le contexte d’occupation témoigne aussi d’un mélange populationnel important, si elles côtoient une nouvelle fois des inhumations, les crémations identifiées sur le site de Lamajone relèvent de petits groupes identifiés topographiquement et les gestes de constitution des sépultures (mobilier, configuration des dépôts ou dispositifs) sont très variables d’un ensemble à l’autre. On retrouve cette même diversité des gestes à Lucciana, où les structures à dépôt de crémation ne présentent cependant pas d’organisation topographique différenciée. Toutefois, leur nombre minoritaire se démarque de ce qui a été observé dans les nécropoles situées en périphérie sud-est et ouest de la ville de Mariana. Ces récentes découvertes engendrent de nouvelles interrogations sur les pratiques funéraires et leur variabilité et notamment, ses particularismes et similarités avec celles du pourtour méditerranéen. Les pratiques funéraires dans ce contexte insulaire, véritable carrefour de la Méditerranée antique occidentale, semblent ainsi davantage relever de coutumes socio-culturelles inhérentes à différents groupes constituant une société très cosmopolite, largement documentées par les autres aspects de l’archéologie (échanges maritimes, modes de production, etc…).

Objetive: Recently in the state of Minas Gerais disasters has happened with the iron ore sector, such as what occurred in the city of Mariana in November 2015 and also in the city of Brumadinho in January 2019, both caused by dam rupture. These tragedies, besides having a social impact such as the death of people, also have consequences for the other sectors of the Brazilian economy. Using the input-output matrix inoperability approach, the article aims to analyze such as the interruption of activity in the iron ore extraction sector in the state of Minas Gerais dissipates to the other sectors. The results obtained suggest that in addition to the iron ore extraction sector, the sectors most affected by this inactivity, although in smaller proportions, are the physical capital production sectors, such as machinery, equipment and automobiles, as well as fuel.

- Abstract
The failures of the Fundao dam in Mariana and the Feijao dam in Brumadinho (Minas Gerais, Brazil) had severe environmental repercussions and caused many fatalities. Both dams failed in the rainy season, were in similar geological terrain in a traditional iron ore mining region, and both failures were due to static liquefaction and flow of the tailings. Other similarities included: similar high-Fe tailings composition, presence of mud, high and steep slopes, upstream dam construction, high levels of tailings saturation, bad management practices, the presence of many monitoring devices, problems with drainage systems, and high levels of risk. Differences included age of the dams, volumes of outflow, amount of environmental damage and number of victims, and warning signs identified before failure. Discussion is presented of the management practices, relevant legislation, and supervision of tailings dams in Brazil, as well as the possible causes of these dam breaks, along with an evaluation of whether the measures taken by National Mining Agency (ANM) will prevent more such accidents. Many other tailings dams are in similar conditions, and it is concluded that further failures may occur, despite the measures taken by the ANM., The failures of the Fundao dam in Mariana and the Feijao dam in Brumadinho (Minas Gerais, Brazil) had severe environmental repercussions and caused many fatalities.

MARIANA PINEDA: A REVOLUTIONARY IN RECREATION OF FEDERICO GARCÍA LORCA García Lorca analyzes the dramatic transposition of the political process of the eponymous heroine grenadine. Celebrated in popular songs who sing their fight, Mariana edge a liberal flag during the government of Don Fernando VII to please the man she loved, and ends up being convicted and executed. Lorca composes a dramatic play based on elements of the character that make telluric discussion intrinsically human affairs from his heroine, with her embroidery, stands for love and freedom. Mariana Pineda who inspires Lorcas s artistic production lived in the early nineteenth century, and served in the fight against a dictatorship, conducting partisan political actions, which committed her to the despotic government of her time. The heroine defends her values of honor and freedom, common feature of other female characters in the traditional Spanish theater, especially the dramaturgist of the Golden Age. Lope de Vega is focused due to telluric features, appreciation of the female and elements of folk tales that gets close to the lorquiano drama. Therefore, a comparative study of the project of the two Spanish authors built on the drama under study Mariana Pineda by Lorca and tragicomedy Fuenteovejuna by Lope de Vega will be held. MARIANA PINEDA: UMA REVOLUCIONÁRIA NA RECRIAÇÃO DE FEDERICO GARCÍA LORCA analisa a transposição dramática, do processo político da heroína granadina homônima. Celebrada em canções populares que entoam sua luta, Mariana borda uma bandeira liberal durante o governo de Don Fernando VII para agradar ao homem que amava, e foi condenada e executada. Lorca compõe uma obra dramática valendo-se de elementos de caráter telúrico que o fazem discutir questões intrinsecamente humanas a partir de sua heroína que, com seu bordado, defende o amor e liberdade. A personagem histórica Mariana Pineda, que inspiraria a produção artística de Lorca, viveu no início do século XIX e atuou na luta contra o regime monárquico de Fernando VII, realizando ações políticas de caráter partidário, o que a comprometeu com o governo despótico de seu tempo. A heroína defende seus valores de honra e liberdade, característica comum a outras personagens tradicionais femininas do teatro espanhol, em especial, dos dramaturgos do Século de Ouro. Lope de Vega será abordado devido aos aspectos telúricos, a valorização do feminino e aos contos populares que o aproximam do drama lorquiano. Assim, será realizado um estudo comparativo das obras dos dois autores espanhóis tomando como base o drama em estudo: Mariana Pineda de Lorca e a tragicomédia Fuenteovejuna de Lope de Vega.

Made available in DSpace on 2022-04-29T08:30:08Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-08-01 The tailings spilled by the Fundão Dam rupture in the Doce River basin (Brazil) had a high pH, elevated sodium (Na) and ether amine, and low soil organic matter. With the aim of decreasing the toxic compounds, we established 2 remediation strategies: treatment 1, phytoremediation with tolerant native species of the Atlantic Forest cultivated on scraped sediment plus the incorporation of organic matter; and treatment 2, phytoremediation with native species plus superficial deposition of organic matter. The experimental site was compared with a degraded site that the dam tailings had reached and with a preserved site, a fragment of preserved Atlantic Forest. After 12 mo, plants showed an outstanding growth, especially after treatment 1 (~4 m), and the remediation procedures resulted in significant decreases in pH (from 8.0 to ~ 6.0), Na (from 154 to 22–35 mg/kg), electrical conductivity, and ether amine (from 6.0 to 0.5 mg/kg) in both treatments. By contrast, ammonium, a product of ether amine degradation, showed a significant increase in the experimental site, along with a significant increase in nitrate and improvement of soil microbial populations assessed by phospholipid fatty acid analysis. The treatments also improved soil fertility in the experimental site, as estimated by soil nutrients, cation exchange capacity, and soil aggregation. Based on the parameters analyzed, a principal component analysis showed that samples from the degraded site and the preserved site clustered in an opposite position and those from the experimental site clustered in an intermediate position but closer to the samples from the preserved site. Overall, our results demonstrated that the remediation procedures adopted were effective and resulted in rehabilitation of a riparian forest contaminated with dam tailings that included Na and ether amine.

La presente investigación propone un abordaje integral de la obra ficcional de Sergio Chejfec, utilizando como hilo conductor al problema de la temporalidad y haciéndolo operar en diferentes planos: a nivel de la trama, para determinar los modos de movimiento y composición de la narración; a nivel de los personajes; a nivel de la construcción de espacialidades; a nivel de la obra, para reflexionar sobre el modo en que la misma se inserta en el presente y se relaciona con otras expresiones artísticas y literarias. El concepto de pensamiento temporal se vuelve central, a partir de los aportes teóricos de Jacques Ranciére en torno a la pensatividad. La lectura se organiza en torno a ciertos ejes que se conectan entre sí, en cuatro capítulos: la visualidad heterocrónica, la pulsión documental, la relación entre literatura e historia y la creación de escenas pensativas.

The present study, part of the research grant The artistic and social impact of the contemporary music of the 21st century from the perspective of the relationship composer-performer-audience (project director Assistant Professor Cristian Bence-Muk, D.Mus.) investigates the structural and rhetoric aspects in the poem Spring, for soprano, clarinet and piano, by Carmen Petra-Basacopol, on the verses of poet Mariana Dumitrescu. The analysis focuses on the relationship between musical techniques (tonal systems, rhythm, timbrality) and the literary text, highlighting the oscillation between rigour (leitmotifs, ostinatos, elements of reprise) and fantasy (improvisational writing – especially for the clarinet –, the madrigal-type discourse).

The disasters caused by mining in Brazil, especially in the state of Minas Gerais, are a historical reality. Since the eighteenth century, when the gold exploration began in the area, there are records of impacts related to the activity, like the siltation of the rivers and the great floods that took place in the town of Mariana. Recently, in 2015 and 2019, the collapse of two tailings dams of iron ore mining caused the greatest socio-environmental disasters recorded in Brazil’s history in the mining sector. Even though the problems ensued by the impacts of mining have differed throughout time, this article strives to discuss something the disasters have in common: the power struggles created by them.

On November 5, 2015, a large tailing deposit failed in Brazil, releasing an estimated 32.6 to 62 million m3 of iron mining tailings into the environment. Tailings from the Fundão Dam flowed down through the Gualaxo do Norte and Carmo riverbeds and floodplains and reached the Doce River. Since then, bottom sediments have become enriched in Fe(III) oxyhydroxides. Dissimilatory iron-reducing microorganisms (DIRMs) are anaerobes able to couple organic matter oxidation to Fe(III) reduction, producing CO2 and Fe(II), which can precipitate as magnetite (FeO·Fe2O3) and other Fe(II) minerals. In this work, we investigated the presence of DIRMs in affected and non-affected bottom sediments of the Gualaxo do Norte and Doce Rivers. The increase in Fe(II) concentrations in culture media over time indicated the presence of Fe(III)-reducing microorganisms in all sediments tested, which could reduce Fe(III) from both tailings and amorphous ferric oxyhydroxide. Half of our enrichment cultures converted amorphous Fe(III) oxyhydroxide into magnetite, which was characterized by X-ray diffraction, transmission electron microscopy, and magnetic measurements. The conversion of solid Fe(III) phases to soluble Fe(II) and/or magnetite is characteristic of DIRM cultures. The presence of DIRMs in the sediments of the Doce River and tributaries points to the possibility of reductive dissolution of goethite (a-FeOOH) and/or hematite (a-Fe2O3) from sediments, along with the consumption of organics, release of trace elements, and impairment of water quality.

Summary The hadal zone, mostly comprising of deep trenches and constituting of the deepest part of the world’s oceans, represents the least explored habitat but one of the last frontiers on our planet. The present scientific understanding of the hadal environment is still relatively rudimentary, particularly in comparison with that of shallower marine environments. In the last 30 years, continuous efforts have been launched in deepening our knowledge regarding the ecology of the hadal trench. However, the geological and environmental processes that potentially affect the sedimentary, geochemical and biological processes in hadal trenches have received less attention. Here, we review recent advances in the geology, biology, and environment of hadal trenches and offer a perspective of the hadal science involved therein. For the first time, we release high-definition images taken by a new full-ocean-depth manned submersible Fendouzhe that reveal novel species with an unexpectedly high density, outcrops of mantle and basaltic rocks, and anthropogenic pollutants at the deepest point of the world’s ocean. We advocate that the hydration of the hadal lithosphere is a driving force that influences a variety of sedimentary, geochemical, and biological processes in the hadal trench. Hadal lithosphere might host the Earth’s deepest subsurface microbial ecosystem. Future research, combined with technological advances and international cooperation, should focus on establishing the intrinsic linkage of the geology, biology, and environment of the hadal trenches., Graphical abstract, Public summary • This paper provides a comprehensive review on hadal geology, environment, and biology, as well as potential interactions among them • For the first time, we release high-definition images taken by a new full-ocean-depth manned submersible Fendouzhe • The hydration of the hadal lithosphere is a driving force that influences a variety of sedimentary, geochemical, and biological processes in the hadal trench • The development of deep-sea technology and international cooperation will greatly promote the progress of hadal science

International audience; Plus de 50 ans après le début des premières fouilles, la basilique paléochrétienne intra-muros, que l’on peut en raison de ses dimensions et de sa position à proximité immédiate de la cathédrale médiévale interpréter comme l’ecclesia episcopalis, pose encore un certain nombre de problèmes majeurs dont l’intérêt dépasse indubitablement le cadre strict du site et même de la Corse. La question de la datation est certainement la principale, du moins c’est bien celle qui a suscité les plus vives discussions depuis sa découverte au début des années 1960...

Este trabalho apresenta a equação Intensidade-Duração-Frequência (IDF) estabelecida para o município de Mariana/MG. As séries de dados utilizadas no estudo foram elaboradas a partir de registros contínuos de precipitação da estação pluviográfica Acaiaca-Jusante, código 02043009 (ANA), localizada no município de Acaiaca. A metodologia para definição da equação utilizando séries de duração parcial está descrita em detalhes em Pinto (2013). A distribuição de frequência ajustada aos dados foi a Exponencial, com os parâmetros calculados pelo método dos momentos-L. As equações adotadas para representar a família de curvas IDF podem ser aplicadas para durações entre 10min e 24h e são recomendadas para tempos de retorno até 50 anos. A aplicação da equação IDF elaborada para o município de Mariana permite associar intensidades de precipitação, nas diferentes durações, a frequências de ocorrência, as quais serão utilizadas no dimensionamento de estruturas hidráulicas. Também pode ser utilizada de forma inversa, ou seja, estimar a frequência de um evento de precipitação ocorrido numa determinada duração, definindo se o evento foi raro ou ordinário, dentro da caracterização de chuva extrema local.

Dentre os maiores desastres brasileiros encontra-se o rompimento da barragem de Fundão, em Mariana (MG), em 2015. Causando danos econômicos e ambientais profundos, o desastre impactou de maneira irreversível a Bacia do Rio Doce. Conforme demonstrado de maneira vasta na literatura, estes choques causam impactos das mais variadas formas, desde a redução nos fatores de produção, impactos ambientais irreversíveis e até mesmo podem afetar os resultados eleitorais. Desta forma, este trabalho busca avaliar através do método de Diferenças em Diferenças, se o ocorrido em Mariana teve efeito direto sobre o desempenho dos candidatos à reeleição nas eleições municipais de 2016. Os resultados mostram que houve impacto do desastre sobre o desempenho eleitoral dos candidatos. Identificou-se um efeito negativo e significativo no desempenho dos políticos quando os municípios por onde concorreram possuíam estações locais de rádio. Verificou-se também que os candidatos foram recompensados pelos eleitores com um maior número de votos quando seus municípios possuíam Plano de Contingência para emergências. Estas evidências contribuem para a discussão acerca de como desastres tecnológicos afetam o desempenho eleitoral. Brazil is a country of continental proportions. Due to its situation, it can be widely affected by disasters, either natural or technological ones. Amongst the biggest disasters in Brazil’s history, we have the rupture of Fundão’s Dam in the city of Marina, Minas Gerais, in 2015. Causing deep economic and environmental impacts, this catastrophe impacted the Rio Doce’s Bay in an irreversible manner. As widely shown in the literature, these disasters can impact a place in various ways, it can severely reduce the production factors, cause deep environmental impacts and it can even change the election outcomes. With that in mind, this dissertation seeks to evaluate, through the Difference in Differences method, if what happened in Mariana had any effects on incumbent’s performances in the 2016’s municipal elections. The results have shown a negative and significantly impact on incumbent’s performance in municipalities that have local radio stations. It has also shown that candidates were rewarded by the population with a higher number of votes when they ran for reelection in municipalities that had a contingency plan for emergencies. These evidences promote a discussion on how technological disasters affect the electoral performance.

CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Configuramo-nos como uma sociedade suicida. É o que os acontecimentos dos últimos anos têm buscado advertir frente a sobrevalorização da economia ante as demandas reais da sociedade global. Fato é que a crescente ambição humana nos ensinou a lançar olhares de cobiça sobre a natureza e seus atributos. Como consequência, impavidamente, essa conta vem sendo cobrada. Algumas vezes, por ação da própria natureza quando da ocorrência de desastres naturais. Noutras, como resultado de nossas próprias ações quando nós, seres humanos, fabricamos nossa própria ruína. No seio das consequências dessas maquinações, podemos citar a atual derrocada mineral mineira, caracterizada pelas copiosas rupturas estruturais em barragens de mineração ocorridas recentemente no estado, como o rompimento da Barragem de Fundão, em 2015, no município de Mariana. A respeito dele, muito se discutiu e ainda se discute sobre as causas que levaram a estrutura ao colapso. Apesar dessa indefinição, comprovadamente, a acelerada corrida mundial em direção à acumulação e reprodução de capitais influiu na configuração do desastre-crime. Antes dele, o agigantamento dos benefícios extrativo-minerais camuflou, por muitos séculos, as consideráveis consequências danosas da prática aos territórios já consolidados e à produção de novas organizações territoriais. Por sua ação, forçou-nos a experimentar, em escala ampliada, os custos da atuação de um modelo econômico que, embora predador, é privilegiado ao longo da história. Entretanto, ainda em tempo de assumir novas posturas, começamos a perceber que a sobrevalorização econômica pode ser, como vem sendo no caso da mineração brasileira, uma bomba relógio. Hoje, quase cinco anos após a ruptura estrutural em Fundão, comprovaremos neste estudo que Mariana e as pessoas atingidas ainda sentem as consequências do desastre por meio de violações e situações que, para além daquelas imediatamente percebidas, se prolongam diante do tempo. Deste modo, essa dissertação propõe sublinhar a nociva capacidade que a mineração brasileira tem de, nos moldes correntes, interferir na paisagem e no território. Isto tendo como objetivo específico o de identificar, no contexto do município de Mariana, elementos de inscrição que marcam, na paisagem municipal, a ressignificação da realidade local após o rompimento da barragem. Para tanto, será essencial uma percepção ampliada e multidisciplinar sobre o termo paisagem e suas qualidades territoriais – condições objetivas para delineação do conceito “Paisagem da Destruição” como unidade de análise prática criada para alcançar as pretensões do presente estudo. Logo, será também necessária uma combinação de estratégias metodológicas pautadas no ato de se deslocar à deriva pelo território estudado, visando integrar os indissociáveis trabalhos teóricos e de campo. Como resultado, teremos o retrato da Paisagem da Destruição em Mariana, que não só comprovará as consequências nocivas das imposições capitalistas sobre os territórios, como também evidenciará, através da identificação dos rastros do rompimento em Fundão, os moldes criativos envolvidos na atual destruição massiva a que são sujeitados nossos territórios de pertencimento. We configure ourselves as a suicidal society. This is what the events of the last few years have sought to warn against the overvaluation of the economy in the face of the real demands of global society. The fact is that the growing human ambition has taught us to take a covetous look at nature and its attributes. As a consequence, this account has been impassively charged. Sometimes, due to the action of nature itself when natural disasters occur. In others, as a result of our own actions when we humans manufacture our own ruin. In the midst of the consequences of these machinations, we can mention the current mineral mining collapse, characterized by copious structural ruptures in mining dams that occurred recently in the state, such as the Fundão Dam rupture, in 2015, in the municipality of Mariana. Much has been discussed about it and there is still debate about the causes that caused the structure to collapse. Despite this lack of definition, the accelerated global race towards the accumulation and reproduction of capital has evidently influenced the configuration of the crime disaster. Before him, the increase in extractive-mineral benefits camouflaged, for many centuries, the considerable damaging consequences of the practice for already consolidated territories and for the production of new territorial organizations. For its action, it forced us to experience, on an expanded scale, the costs of operating an economic model that, although a predator, has been privileged throughout history. However, just in time to take on new stances, we are beginning to realize that economic overvaluation can be, as has been the case with Brazilian mining, a time bomb. Today, almost five years after the structural rupture in Fundão, we will see in this study that Mariana and the people affected still feel the consequences of the disaster through violations and situations that, in addition to those immediately perceived, extend over time. In this way, this dissertation proposes to underline the harmful capacity that Brazilian mining has, in the current mold, to interfere in the landscape and in the territory. This with the specific objective of identifying, in the context of the municipality of Mariana, elements of inscription that mark, in the municipal landscape, the resignification of the local reality after the rupture of the dam. To this end, an expanded and multidisciplinary perception of the term landscape and its territorial qualities will be essential - objective conditions for delineating the concept "Landscape of Destruction" as a unit of practical analysis created to achieve the aims of this study. Therefore, a combination of methodological strategies based on the act of moving adrift through the studied territory will also be necessary, aiming at integrating the inseparable theoretical and field works. As a result, we will have the portrait of the Landscape of Destruction in Mariana, which will not only prove the harmful consequences of capitalist impositions on the territories, but will also show, through the identification of the traces of the rupture in Fundão, the creative molds involved in the current massive destruction a that our territories of belonging are subjected.

Em menos de quatro anos da tragédia de Mariana (2015), a Vale protagonizou mais um episódio, em Brumadinho (2019), consolidado como o maior desastre ambiental em termos de perda de vidas humanas. Para dar voz aos afetados pelas tragédias, a mídia assume papel central com seu poder de influenciar a opinião pública. Baseado no relatório Media Ownership Monitor Brasil (2017), o presente trabalho buscou analisar notícias publicadas em portais jornalísticos online brasileiros G1 e Folha de São Paulo, e nos portais internacionais BBC e The New York Times sobre as tragédias. Recorreu-se à análise de discurso crítica (ADC), utilizando-se o software webQDA no tratamento e codificação de dados, para analisar quais os atores mais acionados para falar sobre as tragédias de Mariana e Brumadinho e como a voz autoral representa os principais atores sociais e institucionais nas notícias. Os veículos reconhecem a responsabilidade do poder público e das empresas. Mas a exclusão das vozes militantes e o não reconhecimento da comunidade local como vítima das tragédias, faz-se questionar se a mídia tem usado sua influência para a mudança de estruturas sociais. Leniência e irresponsabilidade dos atores, especialmente, pelos governos e grandes empresas, têm gerado graves custos ambientais, políticos e sociais para o Brasil.

Economy and Rhetoric of Exchange in Early Modern SpainbyEduardo German RuizDoctor of Philosophy in Hispanic Languages and LiteratureUniversity of California, BerkeleyProfessor Ignacio Navarrete, ChairIn this dissertation I analyze four canonical works (Lazarillo de Tormes, La Vida es Sueño, "El Celoso Extremeño," and Heráclito Cristiano) with the goal of highlighting material-economic content and circumstantial connections that, taken together, come to shape selfhood and identity. I use the concept of sin or scarcity (lack) to argue that Lazarillo de Tormes grounds identity upon religious experience and material economy combined. In this process the church as institution depends on economic forces and pre-capitalistic profit motivations as well as rhetorical strategies to shape hegemonic narratives. Those strategies have economic and moral roots that, fused together through intimate exchanges, surround and determine the lacking selfhood represented by the title character. La Vida es Sueño begins with defective selfhoods, too. Segismundo and Rosaura must negotiate spatial reinsertions and organic reconstitutions through material and rhetorical exchanges that, in the end, also shape their identities. One of the rhetorical exchanges in Calderón's play adopts the form of an intertextuality, specifically a pretextuality that harks back to one of El Conde Lucanor's medieval examples, which is grounded upon the "material" notion of hunger and the related theme of the master-and-slave dynamic between an ignorant master and his wise servant. In the Cervantes tale of the jealous man this dynamic of mutual inscription undergoes a renewal via the capitalistic and colonial circumstance faced by Carrizales, the protagonist. First he has to escape his circumstance; then he has to undergo reinsertion in order to survive as a functioning but deeply troubled self. His project of a viable selfhood appears unachievable unless through the added space and agency of colonial alterity. Only in this way can the subject be fulfilled and hegemonic narrative reconstituted, even if an ultimate or potential downfall also dooms the protagonist. Hence the slave plays an essential role in the formation of hegemonic identity (represented by Carrizales). The slave, one of the incarnations of dominant discourse, occupies an interstitial space, which allows him to expose, undermine, and ultimately make available to discourse such transformative powers as are required for hegemonic continuation. Finally I study Francisco de Quevedo's metaphysical poetry in Heráclito Cristiano and trace there some of the colonial metaphors that, through their economic weight, pull the metaphysical content towards the sinner's physical suffering, manifested psychologically as a need for conversion and a keen awareness of grotesque death.

The cities of Ouro Preto and Mariana were the center of intense gold mining activities in the colonial period (Eighteenth century); this has left remnants and traces up to the present time. After the end of the mining activities and their related cities, this setting was preserved until the 1970s, when the occupation of these urban areas began to take place. At this time, there was much degradation of the former mines due to the unawareness of the importance of these buildings. In the 1990s, some studies were conducted in order to preserve the heritage of these areas, by registering and mapping mine ruins, structures and underground galleries. Today there is a good knowledge of the existing archaeological collection. In this context, there is great demand to announce the existence, the importance and the studies made with this collection to the local communities. Thus, the present extension project was designed to fill in this gap and encourage greater participation of the population in the preservation of this archaeological heritage, seeking to create a link between the existing academic knowledge and the communities located where there was gold extraction in the eighteenth century. The project focused on five communities; however, in two of them, external factors prevented the continuity of the work. The main activities were the inventory and collection of data and information about the places, meetings and workshops with the communities addressing the heritage and the history of the gold mining in the eighteenth century, as well as tours in the archaeological areas and discussions on the subject. The project also focused on mapping and evaluating of the stability of some underground mines that are currently explored for tourism by residents of one of the communities. [ABSTRACT FROM AUTHOR]

The present study, part of the research grant The artistic and social impact of the contemporary music of the 21st century from the perspective of the relationship composer-performer-audience (project director Assistant Professor Cristian Bence-Muk, D.Mus.) investigates the structural and rhetoric aspects in the poem Spring, for soprano, clarinet and piano, by Carmen Petra-Basacopol, on the verses of poet Mariana Dumitrescu. The annalysis focuses on the relationship between musical techniques (tonal systems, rhythm, timbrality) and the literary text, highlighting the oscillation between rigour (leitmotifs, ostinatos, elements of reprise) and fantasy (improvisational writing - especially for the clarinet -, the madrigal-type discourse).

A novel chemolithoautotrophic hydrogen-oxidizing and sulfur-reducing bacterium, strain 496Chim, was isolated from a deep-sea hydrothermal vent chimney collected from the hydrothermal field at the summit of Nikko Seamount field, in the Mariana Arc. Cells were rods or curved rods, motile by means of a single polar flagellum. Growth was observed between 15 and 45 °C (optimum 37 °C; doubling time, 2.1 h) and between pH 5.3 and 8.0 (optimum pH 6.0). The isolate was a strictly anaerobic, obligate chemolithoautotroph capable of growth using molecular hydrogen as the sole energy source, carbon dioxide as the sole carbon source, ammonium or nitrate as the sole nitrogen source, and elemental sulfur as the electron acceptor. The G+C content of genomic DNA was 35 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the new isolate belonged to the class Epsilonproteobacteria, but the isolate was distantly related to the previously described Epsilonproteobacteria species potentially at the genus level (<90 %). On the basis of its physiological and molecular characteristics, strain 496Chim (=DSM 22050 = JCM 15747 = NBRC 105224) represents the sole species of a new genus, Thiofractor, for which the name Thiofractor thiocaminus is proposed.

92. The spread of the new humanism.

Tuck, Richard
- Abstract
SPAIN AND SPANISH ITALY The last words of Lipsius' De magnitudine Romana (1598) represent one important way in which the Tacitist vision would now go – into a destruction not merely of the constitutional order within states, but (as he had foreshadowed in his De constantia fourteen years previously) of patriotism itself, in the interests of security. The insights of the new humanism had been applied by its first generation – men like Corbinelli or Pasquale, or Lipsius himself in his Politicorum – to the problems of their own states, riven by civil war or governed by the memory of it. But by the 1590s, Europe as a whole could now be seen as a society broken by civil war between nations, whose reconstruction called for a new imperialism. This was a message which – of course – a Spanish or Habsburg audience above all was ready to hear, and there is no sign that even in the troubled world of the 1590s it felt that the Habsburgs could not take on this role. In Italy, in particular, writers in this new genre in the 1590s began to make this theme explicit, and to expand their horizons from the small absolutisms of the peninsula which their predecessors in the 1580s had analysed. The first and in many ways the classic expression of this came in a series of works by a Piedmontese, Giovanni Botero. [ABSTRACT FROM AUTHOR]

Gies, David Thatcher
- Abstract
By 1870, notwithstanding the chaos which dominated the political panorama, Spain's theatres seemed to be healthy and thriving. According to El Entreacto of 4 March 1871, “Hay en España 335 teatros con 169.376 localidades, donde se celebra por término medio de cada año 8.000 funciones dramáticas, 1.000 de ópera y 3.000 de zarzuela” (“Spain has 335 theatres with 169,376 seats, where on average some 8,000 dramatic works, 1,000 operas, and 3,000 zarzuelas are put on each year”). Fifteen of these theatres were in Barcelona, eleven in Madrid (although Madrid had more total seats than Barcelona), four each in Cádiz and Zaragoza, three each in the Balearic Islands, Córdoba, Sevilla, and Valladolid, two each in Alicante, La Coruña, Granada, Lérida, Málaga, Salamanca, and Valencia, and one in every other provincial capital except Castellón, Logroño, and Toledo. There existed some 45 dramatic societies which promoted theatre in the provincial capitals. These statistics, if accurate, are extraordinary, for they reveal a lively interest in theatre and a significant rise in the number of playhouses from just a decade previously - 91 in capital cities (up from 74) and 244 in small towns (up from 219). Printed texts were also readily available and thereby increased public knowledge of and attention to the theatre. Several publishers dominated the industry of printing inexpensive editions of recent plays. [ABSTRACT FROM AUTHOR]

94. The self-defence of protestants.

Scott, Jonathan
- Abstract
For God's sake have a strict eye to Mr S[ydney]. The Whigs have great Expectations of him. And when the Protestants of the Low-Countries were so grievously oppressed by the duke of Alva, why should they not make use of all the means that God had put into their hands for their deliverance? … by resisting they established a most glorious and happy Commonwealth, the strongest pillar of the Protestant Cause now in the world. Somme say the protestants of Holland, France, or … Piedmont were guilty of treason, in bearing arms against their princes, but [this] is ridiculous … when it is certaine, they sought noe more than the security of their own lives. Noblemen, Cittyes, Commonaltyes have often taken armes … to defend themselves, when they were prosecuted upon the account of religion. SIDNEY'S CAUSE The beginning of the end of the Restoration crisis came, as we have seen, with a re-establishment both in the King's Declaration and in the minds of most people of the historical necessity of the Restoration. What followed, from 1681 to 1684, was a replay in miniature of many elements of that earlier event. One of these was the punishment of protestant dissent, and it was this which re-established for the Discourses, and the practical design underlying it, the same general context as for Sidney's Court Maxims.

INTRODUCTION After eighteen years on the continent, seventeen of them in exile, Sidney landed in England in late September 1677. He may have arrived at the Castle at Dover, of which he had been commander almost thirty years before. From the Kentish coast there was not far to travel to Penshurst, where his father was to die five and a half weeks later. Sidney seems to have returned alone, though doubtless accompanied by the usual ‘domesticks’. Despite the later reference to a daughter, to marry his ‘valet’ from Nerac, Joseph Ducasse, there is no evidence that such a person travelled with him now. [ABSTRACT FROM AUTHOR]

96. The shape of the future.

Scott, Jonathan
- Abstract
Everyone agrees that the Whigs possessed an impressive political organisation … Yet on the level of detailed information as to the operations of this organisation, the evidence remains scanty. Of course, this organisation did not appear on the surface. Attempting to preserve an impression of spontaneity the Whig press was intentionally vague. The Restoration crisis, from 1678 to 1683, was the second of seventeenthcentury England's three crises of popery and arbitrary government. It was therefore, from the perspective of the historian, linked to both its predecessor of 1638–42 and its successor of 1687–9. What follows is not an attempt to deny any historical links with the latter. Indeed seventeenthcentury England's ‘troubles’ cannot be understood without considering all three crises, and the relationship between them. What will be attempted in the following chapters is the recovery of the perspective on this crisis of contemporaries themselves. Contemporaries, obviously, could not predict the future. They did not hinge their political interpretations upon prophecy. But they could, and they did, remember the past. In the Restoration period they could not forget it. They could be, and to some extent they were, the prisoners of memory. Historians, on the other hand, have been more interested in linking the crisis of 1678–83 with the shape of the future: the future exclusion of James from the throne; the future birth of parties.

Abstract: A detailed petrologic and mineralogic study was carried out on serpentinized peridotites dredged from the southern landward slopes of the Mariana Trench, in order to reveal the serpentinization process of these unusual rocks and to identify the sole presence of the mineral lizardite. The constituent minerals of these southern Mariana forearc peridotites are olivine, amphibole and spinel, as well as serpentine, chlorite and talc. Compared with serpentinite seamounts, the serpentinized peridotites from the southern Mariana forearc are characterized by the absence of magnetite and brucite, and the common presence of talc; besides, the serpentine mineral variety is simplex, only lizardite. Combining mineral chemistry and mineral phase relationships, we conclude that (1) the absence of magnetite in the serpentinized peridotites is due to incomplete serpentinization, other than magnetite, the iron end-member in olivine forms Fe-rich brucite and Fe-rich serpentine; (2) brucite is not stable with high silica activity, reacting with later SiO2-rich fluid and then forming lizardite, leading to a lack of brucite in these serpentinized peridotites; (3) the occurrence of talc is the result of later SiO2-rich fluid reactions with lizardite; and (4) the reason for the sole occurrence of lizardite is that the temperature condition of our study area was not high enough for the formation of antigorite (which is stable at >500°C). Despite the broad overlap of lizardite and chrysotile in growth temperature, differences in the modes of occurrence of lizardite and chrysotile, such as the scarcity of H2O, low porosity and permeability, as well as the actual situation of initial serpentinization in the study area, result in the absolute prevalence of lizardite over chrysotile in the area.

Abstract: We use a petrological model (pHMELTS), coupled with a 2D thermal and variable viscosity flow model (ConMan), to describe and compare fundamental processes occurring within subduction zones. We study the thermal state and phase equilibria of the subducting oceanic slab and adjacent mantle wedge and constrain fluid flux. Using a Lagrangian particle distribution to perform thousands of thermodynamically equilibrated calculations, the chemical state of the domain is continuously updated. Compositionally and thermally dependent buoyancy and viscosity terms provide a consistent linkage between the effect of water addition to and flow within the mantle wedge. We present seven model cases that span normal ranges in subducting slab age, convergence velocity, and slab dip angle. In all models, the coupling between chemistry and dynamics results in behavior previously unresolved, including the development of a continuous, slab-adjacent low-viscosity channel (LVC) defined by hydrous mineral stability and higher concentrations of water in nominally anhydrous minerals (NAM). As the LVC evolves to fluid saturation, slab-derived components are able to migrate vertically upwards to the water-saturated solidus, forming a melting region that bounds the top of the LVC. The LVC develops due to fluid ingress into the mantle wedge from the dehydrating slab, and can be responsible for slab decoupling, large-scale changes in the wedge flow field, and a mechanism by which hydrated slab-adjacent mantle material can be transported to the deep mantle. Varying model parameters indicates that slab age and slab dip angle exert primary control over LVC shape and thickness, due to changing fluid release patterns within the slab. Younger slabs tend to have thinner, more uniform LVCs, while older slabs tend to have a thinner LVC at shallow depths with a large increase in LVC thickness at ∼100 km depth. Slab convergence velocity appears to have a secondary role in controlling LVC shape. [Copyright &y& Elsevier]

Abstract: We developed a mechanical model for the nonlinear, coupled system of plate subduction and back-arc spreading on the basis of mathematical formulation for internal deformation due to a moment tensor in an elastic–viscoelastic layered half-space under gravity. In our modeling the plate subduction and the back-arc spreading are rationally represented by the increase of tangential displacement discontinuity at the plate interface and normal displacement discontinuity at the spreading center, respectively. Through 3-D numerical simulation with this model we obtained a possible scenario for the tectonic evolution of back-arc basins as follows. At the first stage, steady plate subduction gradually forms tensile stress fields in the back-arc region. When the accumulated tensile stress reaches a critical level, back-arc spreading starts at a structurally weak portion of the overriding plate. The back-arc spreading pushes out the frontal part of the overriding plate toward the plate boundary and leads to the increase of slip rates at the plate interface. The local increase of slip rates at the plate interface produces additional tensile stress in the back-arc region. The incremental tensile stress is canceled out by further back-arc spreading. Such a feedback mechanism is necessary to maintain steady back-arc spreading. The long duration of slip-rate excess due to back-arc spreading leads to the gradual protrusion of the plate boundary toward the descending plate (trench retreat). As the plate boundary moves away from the back-arc spreading center, the accumulation rate of tensile stress at the spreading center gradually decreases, and the slip-rate excess at the plate interface due to back-arc spreading also decreases. Then, the original back-arc spreading center becomes less effective in releasing the tectonic tensile stress, and new active back-arc spreading will start somewhere closer to the plate boundary. Such a qualitative scenario accords with the evolution history of back-arc basins in the Mariana region. We obtained the slip-rate excess of 7 mm/year at the plate interface and the 20 km trench retreat for the last 4.5 Myr. These simulation results are significantly smaller than observations in the Mariana region. The discrepancy between simulation results and observations can be ascribed to the effect of the negative buoyancy acting on cold descending slab, which advances spontaneous plate subduction and directly increases the slip-rate excess and the trench retreat in our model.

Serpentinite seamounts, representing some of the first material outputs of the recycling process that takes place in subduction zones, are found on the outer Mariana forearc. Multichannel seismic (MCS) and bathymetric data collected in 2002 image the large-scale structures of five seamounts, as well as the pre-seamount basement geometry and sediment stratigraphy. We present data from three edifices that provide insights into seamount growth and internal deformation processes and allow us to support the interpretation that serpentinite mud volcanoes are formed by the episodic eruption of mud flows from a central region. The presence of thrust faulting at the base of Turquoise and Big Blue Seamounts, along with the low surface slopes (5°–18°) of all the seamounts studied, lead us to infer that these edifices spread laterally and are subject to gravitational deformation as they grow. Numerical simulations using the discrete element method (DEM) were used to model their growth and the origins of features that we see in MCS sections, such as basal thrusts, inward-dipping reflections and mid-flank benches. The DEM simulations successfully reproduced many of the observed features. Simulations employing very low basal and internal friction coefficients (∼0.1 and ∼0.4, respectively) provide the best match to the overall morphology and structures of the serpentinite seamounts. However the simulations do not capture all of the processes involved in seamount growth, such as withdrawal of material from a central conduit leading to summit deflation; compaction, dewatering and degassing of mud flows; mass wasting in the form of sector collapse and growth upon a dipping substrate. A strong reflection beneath the summit of Big Blue, the largest serpentinite seamount on the Mariana forearc, represents the floor of a summit depression that has been partially in-filled by younger muds, supporting the idea that serpentinite seamounts grow by episodic mud volcanism. Boundaries of mud-flow units are visible in bathymetric data and as normal polarity, subhorizontal reflections on seismic profiles. Big Blue Seamount displays complex nesting relationships as it merges with other seamounts to form a large, composite edifice. Flank flows of serpentinite muds on Big Blue and Celestial Seamounts downlap pre-existing forearc substrate. The interface between serpentinite seamounts and the underlying forearc sediments is represented by a reverse polarity reflection beneath Big Blue and Celestial Seamounts, suggesting that the substrate is undercompacted/overpressured and may be a zone of fluid migration. DEM simulations suggest that this boundary represents a distinct décollement along which the seamounts slide laterally. In contrast, Turquoise Seamount grows laterally, not by stable sliding along the top of forearc sediments, but by incorporating them into large basal thrusts. [ABSTRACT FROM AUTHOR]
