Characterization of the Second Parcel of the Alternative Buffer Material (ABM) Experiment — I Mineralogical Reactions
Authors: Kaufhold S. , Dohrmann R. , Götze N. , Svensson D. 
Published: March 2017

AbstractThe performance of bentonite barriers for high level radioactive waste (HLRW) disposal is currently being tested in various real-and up-scale disposal tests. One of the disposal tests, the ABM test (ABM = alternative buffer material), was conducted by SKB (Svensk Kärnbränslehantering) as a mediumscale experiment at the Äspö hard rock laboratory in Sweden. The present study deals with the second parcel (ABM-II), which was retrieved after 6.5 years with 2.5 years of water saturation and 3–4 years of heating up to 141°C. Nine different bentonites and two marine clays were tested to investigate the performance. The aim of the study was to provide a detailed characterization of the mineralogical and chemical changes that took place in ABM-II, compare the findings with ABM-I (the first of the six test parcels), and try to draw some general conclusions concerning the use of bentonites in such geotechnical barriers. The ABM-II test parcel revealed a set of reactions that a HLRW bentonite might undergo. The most prominent reaction was the rather complete exchange of cations, which was discussed in a second part to this publication (II — cation exchange; Dohrmann and Kaufhold, 2017). The corrosion of the Fe in metal canisters was observed, but no discrete corrosion product was identified. At the interface of bentonite and the metal canister, the formation of smectite-type trioctahedral clay minerals was observed. In contrast to the ABM-I test, anhydrite was present in many of the bentonite blocks of the ABM-II test. In most concepts used for HLRW disposal in crystalline rocks, a temperature below 100°C at the canister surface was applied to avoid boiling. In the ABM-II test, boiling of water was possibly observed. Throughout the experiment, a pressure/water loss was recorded in the upper part of the geotechnical barrier and water was added to maintain pressure in the bentonite. As a result of evaporation, NaCl crusts might have formed and the barrier was partly disintegrated. These results demonstrated that a reasonable assumption is that no boiling of water occurs in disposal concepts in which a pressure loss can occur.
The power of the imagination of historical distance: Melechesh’ ‘Mesopotamian Metal’ as a musical attempt of solving cultural conflicts in the twenty-first century
Authors: Pichler Peter 
Published: March 2017

Abstract
As an interdisciplinary but distinct field of cultural research, metal music studies is, as a research discourse, structurally interwoven with post-modern and post-colonial cultural history. In this article, the author examines the ways the music of the Middle Eastern extreme metal band Melechesh, called ‘Mesopotamian Metal’ by the artists themselves, constructs a hybrid cultural pattern that could help us solving cultural conflicts in the globalized world of the twenty-first century. Mesopotamian Metal constructs an innovative cultural discourse, hybridizing fragments of different ‘Western’, ‘Eastern’ and ‘Oriental’ streams of culture. Its main power lies in its way of historical storytelling: it uses the logic of hybridization, via the imagination of historical distance, to provide us with an innovative historical narrative, fashioned in the globally understood cultural outfit of extreme metal music. Explaining this empirical case by post-colonial hybridization theory adds new aspects to current research debates on the interconnections between global extreme metal discourse and regional/local cultures in metal music studies.

Abstract
Two- and three-dimensional direct numerical simulation (DNS) of turbine cascade flow at low Reynolds number with heat transfer are performed using high-order finite difference method. Two-dimensional laminar computation which is used to construct the initial flow of three-dimensional DNS fails to predict Stanton number on the second half of suction side where the flow is turbulent in experiment. In three-dimensional DNS, transition is triggered by periodic blow-and-suction disturbances. Numerical experiments show that phase randomness of the disturbance is not necessary to trigger the transition which can be induced by disturbances with fixed phases. In a range of time fundamental frequency of disturbance, when increasing the frequency, transition moves downstream. When time fundamental frequency is big enough, transition disappears. With fixed space phases, time phases and selected time fundamental frequency, time averaged pressure and Stanton number distributions of three-dimensional DNS coincide with the experimental datum. Averaged velocity and temperature, Root-Mean-squares (RMS) of velocity pulse，temperature pulse, Reynolds shear stress and heat flux are extracted from the DNS database. All statistics agree well with experimental and theoretical results which verify the accuracy of present database.
Dopamine Inhibition Differentially Controls Excitability of Substantia Nigra Dopamine Neuron Subpopulations through T-Type Calcium Channels

Published: March 2017

While there is growing appreciation for diversity among ventral tegmental area dopamine neurons, much less is known regarding functional heterogeneity among the substantia nigra pars compacta (SNc) neurons. Here, we show that calbindin-positive dorsal tier and calbindin-negative ventral tier SNc dopaminergic neurons in mice comprise functionally distinct subpopulations distinguished by their dendritic calcium signaling, rebound excitation, and physiological responses to dopamine D2-receptor (D2) autoinhibition. While dopamine is known to inhibit action potential backpropagation, our experiments revealed an unexpected enhancement of excitatory responses and dendritic calcium signals in the presence of D2-receptor inhibition. Specifically, dopamine inhibition and direct hyperpolarization enabled the generation of low-threshold depolarizations that occurred in an all-or-none or graded manner, due to recruitment of T-type calcium channels. Interestingly, these effects occurred selectively in calbindin-negative dopaminergic neurons within the SNc. Thus, calbindin-positive and calbindin-negative SNc neurons differ substantially in their calcium channel composition and efficacy of excitatory inputs in the presence of dopamine inhibition.SIGNIFICANCE STATEMENTSubstantia nigra dopaminergic neurons can be divided into two populations: the calbindin-negative ventral tier, which is vulnerable to neurodegeneration in Parkinson's disease, and the calbindin-positive dorsal tier, which is relatively resilient. Although tonic firing is similar in these subpopulations, we find that their responses to dopamine-mediated inhibition are strikingly different. During inhibition, calbindin-negative neurons exhibit increased sensitivity to excitatory inputs, which can then trigger large dendritic calcium transients due to strong expression of T-type calcium channels. Therefore, SNc neurons differ substantially in their calcium channel composition, which may contribute to their differential vulnerability. Furthermore, T-currents increase excitation efficacy onto calbindin-negative cells during dopamine inhibition, suggesting that shared inputs are differentially processed in subpopulations resulting in distinct downstream dopamine signals.

Placebo treatments can strongly affect clinical outcomes, but research on how they shape other life experiences and emotional well-being is in its infancy. We used fMRI in humans to examine placebo effects on a particularly impactful life experience, social pain elicited by a recent romantic rejection. We compared these effects with placebo effects on physical (heat) pain, which are thought to depend on pathways connecting prefrontal cortex and periaqueductal gray (PAG). Placebo treatment, compared with control, reduced both social and physical pain, and increased activity in the dorsolateral prefrontal cortex (dlPFC) in both modalities. Placebo further altered the relationship between affect and both dlPFC and PAG activity during social pain, and effects on behavior were mediated by a pathway connecting dlPFC to the PAG, building on recent work implicating opioidergic PAG activity in the regulation of social pain. These findings suggest that placebo treatments reduce emotional distress by altering affective representations in frontal-brainstem systems.SIGNIFICANCE STATEMENTPlacebo effects are improvements due to expectations and the socio-medical context in which treatment takes place. Whereas they have been extensively studied in the context of somatic conditions such as pain, much less is known of how treatment expectations shape the emotional experience of other important stressors and life events. Here, we use brain imaging to show that placebo treatment reduces the painful feelings associated with a recent romantic rejection by recruiting a prefrontal-brainstem network and by shifting the relationship between brain activity and affect. Our findings suggest that this brain network may be important for nonspecific treatment effects across a wide range of therapeutic approaches and mental health conditions.
Persistence of Baroque Trauerspiel in Tom Stoppard’s Rosencrantz and Guildenstern Are Dead as a Postmodern Literature: Rejection of Metanarrative
Authors: Mostafalou Abouzar , Moradi Hossein 
Published: March 2017

Metanarrative is a conventional style of narration in literature which features tragedy in Greek model’s sense. In this type, metanarrative follows the conventions set by Aristotle; these conventions range different ones; time, one of the most important elements of narration, is linear. Therefore, in this regard, tragedy follows succession of events based on chronological orders. Moreover, metanarrative signifies stability of human deeds and meanings; therefore, what human beings do or say is stable and truthful. Moreover, in metanarrative, death is considered to be the ceasing moment of life in which continuation of life takes place in afterlife. This means that there is no ending or beginning since life is just a confusing cycle. Melancholy is used in Freudian sense that signifies suffering from hallucination and paranoia. These key concepts have composed metanarrative in conventional sense, and consequently metanarrative has been the base of tragedies in Greek sense. However, by emergence of Benjamin’s ideas regarding Trauerspiel, the fundamentals of metanarrative were challenged. Therefore, postmodern narrative started to take the place of conventional metanarrative, so that the ideas of time, language, melancholy, and death approached postmodern features. The failure of metanarrative and approach to postmodern literature can be traced in Tom Stoppard’s Rosencrantz and Guildenstern Are Dead in which there is no chronological order within the play. Moreover, conveying meaning through language fails, and life as an endless cycle, dominates the whole play. Consequently, the metanarrative and tragedy genre of Tom Stoppard’s Rosencrantz and Guildenstern Are Dead can be replaced by postmodern narrative and Baroque Trauerspiel.
LA CONVERSATION ENTRE MARIE ET JÉSUS AUX NOCES DE CANA : ÉTUDE PRAGMATIQUE D’UN ENCHAÎNEMENT CONVERSATIONNEL SÉMANTIQUEMENT INCOHERENT
Authors: GBAKRE Jean-Marie Andoh 
Published: March 2017

RÉSUMÉ. La sémantique consacre l’explicite dans l’usage syntaxique des mots. Cependant, il existe des niveaux d’actes de langage où la fluidité du lien sémantique observe une rupture. La conversation entre Marie et Jésus, lors des noces de Cana, fait cas d’étude. Face à la limite de l’interprétation sémantique constatée dans cet échange qui à l’air d’un dialogue de sourd, et qui pourtant comporte une finalité perlocutoire prégnante, la pragmatique est convoquée. Comment se perçoit la limite de l’interprétation sémantique en conversation de façon générale, et, qu’est-ce qui caractérise l’échange entre Marie et Jésus ? Comment se fait dans ce dialogue le passage de l’illocutoire au perlocutoire ? Le traitement de ces questions constitue le schéma procédural de la réflexion qui entend dégager la solidarité de la pragmatique face aux limites de la sémantique. Mots-clés : cognition, cohérence sémantique, efficacité pragmatique, interaction, variables actionnelles. ABSTRACT. The semantics devotes explicit in the syntactic use of words. However, there are levels of speech acts where the fluidity of the semantic link observes a break. The conversation between Mary and Jesus at the wedding at Cana is a case study. Faced with the limits of the semantic interpretation found in this exchange that looks a dialogue of the deaf, and yet has a purpose perlocutory pregnant, pragmatics is called. How to perceive the limits of semantic interpretation in general conversation and what characterizes the exchange between Mary and Jesus? How is this dialogue in the passage of the illocutionary perlocutory? The treatment of these issues is the procedural pattern of thinking which intends to generate the solidarity of pragmatic face to the limits of semantics. Keywords: actionals variables, cognition, consistency semantics, interaction, pragmatic efficiency.
