Indigenista perspectives in Argentine metal music
Authors: Belén Calvo Manuela 
Published: February 2018

Abstract

Indigenismo was a literary trend that originated in 1920s Peru and that further developed in many Andean countries, including Argentina. In Argentina, indigenista literature represented a reaction to the hegemonic ideals of civilization-versus-barbarism, which were deployed to justify the murdering and subjugation of indigenous peoples. Starting in the 1980s, many metal bands in Argentina adopt the same approach. This article will examine the way in which metal music in Argentina uses a twofold logic that simultaneously defends all aboriginal traits while condemning all foreign influences, all of this as bands use rhetorical devices that originate in metal music, devices external to the indigenous world and originating from a context of globalization and capitalism. This meditation is based on a socio-semiotic analysis of the output of a handful of bands.
‘Severed Reality’: Representations of reality in Salvadoran tribal metal
Authors: Pack Christian 
Published: February 2018

Abstract
As a musical discourse, heavy metal often asserts its own view of reality that is antagonistic to the ‘popular’ world-view of society. This dominant framework that is at work in the world, at large, is the Modern/Western framework of reality, which is highly dependent on the discourses of Christianity, capitalism and democracy and which has mainly been spread through imperialism. What has allowed this framed reality to succeed at such a large scale is what William Egginton calls ‘theatricality’, the foundation of our modern understanding of the world. However, no matter how strong the dominant frame may be, separate frames always exist simultaneous and exterior to it. By applying Heidegger’s understanding of the ‘world as picture’, I can demonstrate that heavy metal music not only creates a separate frame with which its listeners and producers experience reality but also how this particular frame, which relies on theatrics and the macabre, tries to intentionally crack or shatter the dominant frame. This process is manifested clearly in the Salvadoran heavy metal community and in Salvadoran ‘tribal metal’. In this setting, Western ideologies have systematically been pushed onto a community that continues to resist them and to create their own meaningful reality. As a part of this study, I have engaged in ethnographic observation and carried out 30 in-depth qualitative interviews during a three-year period. Results evidence how the local heavy metal community exists within Salvadoran society while simultaneously being antagonistic to most of its values and attempting to ‘rewrite’ the popular framework with which Salvadoran ‘reality’ is generally articulated. This is done through an invocation of its own indigenous past in the tribal metal genre.
Media representations of metal music in the Dominican Republic: Between oppression and social resistance
Authors: Mendoza Sigrid , Varas-Díaz Nelson , Rivera-Segarra Eliut , Vélez Carlos 
Published: February 2018

Abstract
Metal music is a global phenomenon, and research addressing its development throughout the world should focus on the local and regional factors that help shape it. The Dominican Republic saw the emergence of a local metal scene in the early 1980s. Unlike other scenes in the Caribbean region, the local media outlets (i.e. newspapers, tv shows, radio shows) have played a crucial role in its development. This article aims to examine the role that media has played in the development and hindrance of the local scene and its interrelation to shifts in the racial/class composition of its members. We carried out ethnographic observations and in-depth qualitative interviews (n=10) with local fans and musicians. All data were analysed and categorized using NVIVO software. In this short article, we discuss how the media played a dual role in the development of the local metal scene. Initially, media representations of metal music contributed to hinder and stigmatize local metal fans. Later, those same media outlets were used by metal fans to counteract stigmatizing representations of metal and expand the scene. Such was the case of the Avanzada Metallica, a local radio show that organized local concerts and informed the metal scene for 20 years. We will discuss how it became a platform to promote local metal bands in the Dominican Republic and Latin America through its organized activities, while simultaneously expanding the scene in terms of its racial and social class composition.
Representaciones musicales en tiempos de violencia: Orígenes del metal peruano durante la crisis general de los años ochenta
Authors: Núñez María de la Luz , Rivas Arturo 
Published: February 2018

Resumen
El presente artículo se pregunta por las motivaciones que llevaron a jóvenes peruanos a expresarse a través del metal en los años 80, apartándose de otros géneros musicales que ya habían sido desarrollados, tales como el hardcore, el punk y el rock subterráneo. En ese sentido, proponemos que sus motivaciones, lejos de tratarse de una simple copia de bandas extranjeras, deben más bien enmarcarse en el contexto de la crisis política, social y económica que tuvo lugar en esa década; situación que recrudeció por el conflicto armado interno entre agentes del Estado y agrupaciones terroristas. Para fundamentar nuestra postura, recurriremos a la metodología genealógica nietzscheana y a algunos conceptos fenomenológicos de Husserl y Scheler, entendiendo al metal como una ‘reacción emocional de respuesta’ frente a los valores preferidos por la sociedad, en relación con la vivencia de la crisis, y a través de distintas capas de conciencia (afectiva, volitiva, cognoscitiva) y modos de conciencia (perceptivo-natural y representacional-estético). Nuestra aproximación es complementada con testimonios de músicos que fueron parte del origen de la escena metal en el Perú.
Musical representation in times of violence: The origins of Peruvian metal music during the general crisis of the eighties
Authors: Núñez María de la Luz , Rivas Arturo 
Published: February 2018

Abstract
This article addresses the motivations that led young Peruvians to express themselves through metal in the 1980s, moving away from other musical genres that had already been developed, such as hardcore, punk and underground rock. In this sense, we propose that their motivations, far from being a mere copy of foreign bands, should rather be framed in the context of the political, social and economic crisis that took place in that decade, a situation that was exacerbated by the internal armed conflict between State agents and terrorist groups. To ground our position, we will resort to the Nietzschean genealogical methodology and phenomenological concepts from Husserl and Scheler, understanding metal as an ‘emotional response reaction’ to the values ​​preferred by society, in relation to the experience of the crisis and through different layers of consciousness (affective, volitional, cognitive) and modes of consciousness (perceptive-natural and representational-aesthetic). Our approach is complemented by testimonies of musicians who were part of the origin of the metal scene in Peru.
Cartas, fitas cassete e fanzines: A circulação do metal no Brasil como modelo da dádiva
Authors: dos Santos Silva Melina Aparecida 
Published: February 2018

Resumo
O artigo aborda as trocas culturais no contexto da cena do metal brasileiro e as relações sociais construídas em torno das materialidades do gênero musical, como cartas, fitas cassete e fanzines. O argumento central é de que estas trocas de itens entre fãs de metal contribuíram para a globalização do gênero musical e tiveram continuidade dos anos 1990 aos 2000, em territórios periféricos, como o Brasil, mesmo com a chegada da Internet. Abordamos esta questão a partir de uma pesquisa online com fãs de metal sobre o papel das trocas de cartas e fitas cassete, mediadas pelos fanzines, para acesso aos produtos culturais. O questionário foi disponibilizado nos grupos dedicados ao metal brasileiro e colecionadores de fitas cassete e fanzines nas redes sociais. A circulação do metal no Brasil será compreendida a partir do paradigma da dádiva, proposto por Marcel Mauss e por suas releituras. Desta forma, ressaltamos a construção de identidades e de laços sociais oferecida pelo intercâmbio cultural.
The aesthetic-sonic shift of melodic death metal
Authors: Hillier Benjamin 
Published: February 2018

Abstract
This article examines the shift in aesthetics and sound that occurred during the development of what came to be called melodic death metal, a sub-genre of metal that developed in the 1990s in Gothenburg, Sweden. I consider the musical aesthetics such as instrumentation, production style and timbre alongside extra-musical aesthetics such as lyrics, cover art and band logos. Thus, I demonstrate how melodic death metal develops its aesthetics and sound in order to differentiate itself from its main influences of Swedish death metal and the New Wave of European Heavy Metal. This article aims to contribute to a growing body of works that is focused on analysing the music at the core of popular music, in particular metal, and develop methods of analysis that deal with musical aesthetics on an equal ground with extra-musical aesthetics. Furthermore, this article aims to discuss in detail specific features of melodic death metal and establish a basis for further examination of the developments of the genre.
Construction and recombinant expression of Pseudomonas aeruginosa truncated exotoxin A in Escherichia coli
Authors: Qaiser Hina , Aslam Farheen , Iftikhar Saima , Farooq Adeen 
Published: February 2018

Pseudomonas aeruginosa exotoxin A (PE) is a bacterial toxin composed of three domains namely: cell binding, translocation and enzymatic domain. The cytotoxic activity of PE is attributed to the enzymatic domain, which inhibits protein synthesis through ADP-ribosylation of EF-2. PE can be genetically modified to fight cancer. In this regard, a truncated and modified form of PE was produced that could be used for more potent immunotoxins. This modified form termed PE38KDEL was completely devoid of cell binding domain and parts of translocation domain II and Ib which are reported to be inessential for cytotoxicity of the toxin. The resultant expressed protein consisted of the essential translocation domain II and catalytic subunit (domain Ib, III). The deletions in the exotoxin A gene for truncated protein production were made via overlapping PCR extension. The amplicon was cloned in pTZ57r-T vector for DNA works and sub cloned in pET22b expression vector. It is demonstrated here that PE38KDEL can be expressed in huge quantities in Escherichia coli by using the recombinant vector PE38KDEL/pET under control of T7 promoter and E. coli host strain BL21 (DE3) CodonPlus. The protein expression was optimized at 0.5 mM IPTG concentration for induction as soon as the OD600 nm reached 0.6 with 6 hours of post induction culturing at 37°C. The recombinant protein was expressed both as soluble and inclusion body forms however the expression of the soluble form was more pronounced.

Existence and Multiplicity Results for Systems of First-Order Differential Equations via the Method of Solution-Regions
Authors: Frigon Marlène 
Published: February 2018

Abstract
In this paper, we establish existence and multiplicity results for systems of first-order differential equations. To this end, we introduce the method of solution-regions. It generalizes the method of upper and lower solutions and the method of solution-tubes. Our results can also be seen as viability results since we obtain solutions remaining in suitable regions. We give conditions insuring the existence of at least three viable solutions of a system of first-order differential equations. Many examples are presented to show that a large variety of sets can be solution-regions.
Sine and cosine type functional equations on hypergroups
Authors: Roukbi Ahmed , Lehlou Fouad , Moussa Mohammed 
Published: February 2018

AbstractLet{(X,*)}be a hypergroup and let{w_{0}}be a fixed measure onX. In this paper we study the two functional equations\langle\delta_{x}*\delta_{y}*\omega_{0},g\rangle+\langle\delta_{x}*\delta_{% \check{y}}*\omega_{0},g\rangle=2g(x)g(y),\quad x,y\in X,and\langle\delta_{x}*\delta_{\check{y}}*\omega_{0},f\rangle-\langle\delta_{x}*% \delta_{y}*\omega_{0},f\rangle=2f(x)f(y),\quad x,y\in X,where{g,f:X\to\mathbb{C}}are continuous and bounded functions to be determined. We express the solutions of the two functional equations in terms of multiplicative maps on{(X,*)}. As an application we give the solution of the two functional equations on polynomial and Sturm–Liouville hypergroups.
Variable G versus the Accelerated Expansion of the Universe
Authors: Colenbrander Bernard G. , Hulscher Willem S. 
Published: February 2018

Abstract
It is shown that the hypothesis of permitting variability of the Newtonian constant G, increasing with the local density of dark matter, implies that there is no need for the introduction of a cosmological constant or accelerated expansion of the universe. A higher value of G in the younger universe leads to an enhanced redshift of the spectra from e.g. supernovae, which results in an estimation of a larger distance and magnitude. Interpreting relevant astronomical observations in terms of both effects leads remarkably to a linear relationship between the redshift and the magnitude of the supernovae throughout the history of the universe. Furthermore it is shown, that from CMB measurements, no reliable conclusions can be drawn about the structure and geometry of the universe. It is concluded that, if the hypothesis survives further tests, no valid evidence is available that would point to an accelerated expansion of the universe and therefore it is not necessary to assume the existence of dark energy.
News From The Erebos Project

Published: February 2018

Abstract
Planets and brown dwarfs in close orbits will interact with their host stars, as soon as the stars evolve to become red giants. However, the outcome of those interactions is still unclear. Recently, several brown dwarfs have been discovered orbiting hot subdwarf stars at very short orbital periods of 0.065 - 0.096 d. More than 8% of the close hot subdwarf binaries might have sub-stellar companions. This shows that such companions can significantly affect late stellar evolution and that sdB binaries are ideal objects to study this influence. Thirty-eight new eclipsing sdB binary systems with cool low-mass companions and periods from 0.05 to 0.5 d were discovered based on their light curves by the OGLE project. In the recently published catalog of eclipsing binaries in the Galactic bulge, we discovered 75 more systems. We want to use this unique and homogeneously selected sample to derive the mass distribution of the companions, constrain the fraction of sub-stellar companions and determine the minimum mass needed to strip off the red-giant envelope. We are especially interested in testing models that predict hot Jupiter planets as possible companions. Therefore, we started the EREBOS (Eclipsing Reflection Effect Binaries from the OGLE Survey) project, which aims at analyzing those new HW Vir systems based on a spectroscopic and photometric follow up. For this we were granted an ESO Large Program for ESO-VLT/FORS2. Here we give an update on the the current status of the project and present some preliminary results.
Atomic diffusion in the atmosphere of Feige 86
Authors: Németh Péter 
Published: February 2018

Abstract
We have revisited the ultraviolet and optical spectra of the blue horizontal branch star Feige 86. The new analysis finds the star cooler and more compact than previously determined. The IUE spectrum of Feige 86 holds numerous unidentified spectral lines of heavy metals, indicating efficient atomic diffusion in the atmosphere. Because diffusion plays a key role in the atmospheres of hot subdwarfs as well, it is indispensable to a better understanding of subdwarf pulsations and evolution. Feige 86 looks like an ideal target to confront diffusion theory with observations and test spectroscopic techniques. Therefore, to advance our general understanding of diffusion in stellar atmospheres we urge for new ultraviolet spectroscopy of Feige 86 at the highest possible resolution with HST/STIS.
An additional pulsating mode (7.35 mHz) and pulsations timing variations of PG 1613+426

Published: February 2018

Abstract
We present the detection of an additional pulsation mode (7.35 mHz) of a subdwarf B star, PG 1613+426, and periodic Observed minus Calculated (O-C) variations for two existing pulsations. PG 1613+426 is near the hot end of the sdB instability strip. One pulsation mode (6.94 mHz) was detected so far by Bonanno et al. (2002) and another pulsation mode candidate (7.05 mHz) was proposed with a confidence level above 90% by Kuassivi and Ferlet (2005). To constrain sdB star evolutional scenarios, this star was monitored in 2010, 2011, 2015, and 2017 as a part of a project for finding companions to sdB stars using the pulsation timing method. The photometric analysis of those data shows an additional 7.35 mHz pulsation mode as well as the previously detected 6.93 mHz mode. However the 7.05 mHz mode was not detected. Nightly amplitude changes of 7.35 mHz mode were observed in the 2011 data, however the 2017 data did not show nightly amplitude shifts. O-C variations were detected in both 6.93 mHz and 7.35 mHz pulsations, indicating that PG 1613+426 may have a low mass companion star. However, more observations are needed to confirm it.
Discrete Functional Analysis Tools for Some Evolution Equations

Published: February 2018

Abstract
We present some discrete functional analysis tools for the proof of convergence of numerical schemes, mainly for equations including diffusion terms such as the Stefan problem or the Navier–Stokes equations in the incompressible and compressible cases. Some of the results covered here have been proved in previous works, coauthored with several coworkers.

AbstractDecomposition of mixed Cu-Fe-Cr hydroxycarbonates was investigated by thermal analysis and in situ XRD and FTIR. TGA and DTA showed that increased preheating temperature removes modifying anions and decreases the spinel crystallization temperature. A disordered oxide phase containing carbonate is initially formed. The carbonate contents and crystallization temperature decreases depend on the Fe
Sensitive Media
Authors: Malinowska Anna , Miller Toby 
Published: February 2018

AbstractThe paper engages with what we refer to as “sensitive media,” a concept associated with developments in the overall media environment, our relationships with media devices, and the quality of the media themselves. Those developments point to the increasing emotionality of the media world and its infrastructures. Mapping the trajectories of technological development and impact that the newer media exert on human condition, our analysis touches upon various forms of emergent affect, emotion, and feeling in order to trace the histories and motivations of the sensitization of “the media things” as well as the redefinition of our affective and emotional experiences through technologies that themselves “feel.”

CFD Simulation of Solid Suspension in a Stirred Reactor Driven by a Dual Punched Rigid-Flexible Impeller
Authors: Gu Deyin , Liu Zuohua , Qiu Facheng , Li Jun , Tao Changyuan , Wang Yundong 
Published: February 2018

Abstract
Solid suspension characteristics were predicted by computational fluid dynamics (CFD) simulation in a stirred tank driven by a dual rigid-flexible impeller and a dual punched rigid-flexible impeller. An Eulerian-Eulerian approach, standard k-ε turbulence model, and multiple reference frames (MRF) technique were employed to simulate the solid-liquid two-phase flow, turbulent flow, and impeller rotation in the stirred tank, respectively. The CFD results showed that dual punched rigid-flexible impeller could increase the axial velocity and turbulent kinetic energy dissipation rate, and decrease the quantity of sediment solid particles compared with dual rigid-flexible impeller. Less impeller power was consumed by dual punched rigid-flexible impeller compared with dual rigid-flexible impeller at the same impeller speed. It was found that punched rigid-flexible impeller was more efficient in terms of solid suspension quality than dual rigid-flexible impeller at the same Pw. The simulated results for the axial solid concentration were in good agreement with the experimental data.
