In Search of the Bigger Picture : The New Irish Art
Authors: Marshall Catherine
Published: December 2015

"...the first thing an artist does is to try and transcend ideas of identity, rather than to go in the opposite direction." These words spoken by Shane Cullen in an interview with Mark Ward {Interface, University of Ulster, Belfast, May 12, 2006) could be used to sum up much of what is relevant in new Irish Art. This essay looks at Irish art made since the mid-nineteen-nineties and points to the new internationalism that is now a characteristic of work from this island. The post-colonial legacy that was an inseparable part of the bagage carried by Irish artists for most of the 20th century has finally been set aside as artists look ahead to a new century and a new millennium. Significantly this liberation is linked to a shift in political, economic and demographic changes. The generation of Irish artists who have come to prominence since 1995 can now look beyond the concerns of their own island to the politics of the death penalty in Texas, the re-presentation of historic events and debates through the multi viewpoints enabled by new media, and global and universal concerns that range from climate change to age-old issues of loneliness and poverty without having to link this to a specific or recognisable Irish context. This essay looks as some of the artworks that have emerged as a result of this new consciousness.
The Saint Patrick's Day Celebration in New York since 2000 : An Ethnic Festival Revisited by the New York Times
Authors: Michaud Marie-Christine
Published: December 2015

Saint Patrick's Day, the Irish National Day, is celebrated in the United States every year, as if the Irish living there had imported their ethnic identity. But, upon closer analysis, it is clear that the American context has transformed the celebration into an Irish-American day, and the study of the coverage of the event by the New York Times since 2000 testifies to a change in the sense of Irishness in the USA at the dawn of the new millennium.
Stratégie électorale et construction d'image : les spots télévisés de Fianna Fâil pour les législatives de mai 2007
Authors: Haigron David
Published: December 2015

En étant reconduit au pouvoir, le parti de Bertie Ahern a touché les dividendes d'une situation économique favorable et d'une image de marque relativement claire et positive. Sur un marché électoral concurrentiel, Fianna Fâil a élaboré une stratégie de positionnement et de communication dont cette image est un élément et dont les spots télévisés sont un instrument. L'étude des spots offre ainsi une illustration révélatrice des enjeux d'une campagne moderne en République d'Irlande.
Synge and the "Savage God"
Authors: Richards Shaun
Published: December 2015

Cet article considère l'oeuvre de J.M. Synge, et surtout Le Baladin du Monde Occidental (1907), dans le contexte de la fusion de l'art et anarchisme du Paris fin-de-siècle dont Ubu Roi (1896) d'Alfred Jarry est la plus célèbre expression théâtrale. En particulier, il suggère que l'oeuvre de Synge se fait l'écho des intentions radicales et révolutionnaires du théâtre d'avant-garde qu'il partage avec Jarry ; dimension qui a été éclipsée par la à le lire uniquement dans le contexte du nationalisme irlandais et du théâtre de l'Abbey.
Performing Artaud in Ireland
Authors: Singleton Brian
Published: December 2015

Two contemporary productions representing the visit of French theatrical visionary Antonin Artaud to Ireland in 1937 are the subject of this paper. One production charted, in a linear fashion, Artaud's journey through Ireland to his eventual deportation, staging along the way representations and embodiments of his delusional state of mind at the time. The second used his epistolary narrative of the events in Ireland as a soundtrack through which to experience an exhibited Artaud in a museum case, living on as an exotic creature forever trapped in both our collective memory and our imagination, haunting and disturbing us. While one re-enacted Artaud's time in Ireland as a performing intervention, the other actually staged the essence of his interventions by disrupting our very notion and experience of performance itself.
Under the Influence Lecoq, the Body, and the Irish
Authors: Leeney Cathy
Published: December 2015

Through an outline exploration of key issues in his training for actors, this paper suggests that the influence of Jacques Lecoq on Irish theatre is at an early stage of development, and that, through individuals and companies linked with Lecoq, its impact may be seen in changing hierarchies in theatre-making, in the expansion and diversification of the creative role of actors, and in the orientation of performance outwards, through the vocabulary of a shared material world.
Lady Gregory s'en va t'en guerre : the Kiltartan Molière
Authors: Poulain Alexandra
Published: December 2015

The article looks at Lady Gregory's translations of four Molière plays into the Kiltartan dialect, and contends that they are part of a cultural battle Gregory is fighting, a complex contribution to the Abbey's project of constructing a national identity. While promoting Kiltartan as target language for the translation of some of the greatest pieces in the French classic repertoire is a means of contesting the hegemony of standard English, specific translation choices also enable Lady Gregory to appropriate Molière 's social criticism and to bring it to bear on the changing Ireland of her time. However, she limits the impact of her gesture of appropriation by shunning to expose her language to the full force of the foreign language as foreign body.
Face to face in word and translation : playing with words and playing with accents in two scenes by Oscar Wilde and G. B. Shaw
Authors: Vatain Julie
Published: December 2015

L'impact immédiat du dialogue, et son incarnation par la voix et le corps des comédiens, modifient au théâtre les enjeux de la traduction. A partir de deux exemples précis de face à face humoristique dans la comédie de mœurs, cet article s'intéresse à la traduction en français du regard critique porté par le dramaturge irlandais sur la société londonienne, et s'efforce d'explorer quelques-unes des difficultés langagières et rythmiques qu'impliquent le jeux sur les tons et les accents.

Rough for theatre I and II and why they stayed that way, or when Beckett's french theatre became irish again
Authors: Penet-Astbury Helen
Published: December 2015

Rough for theatre 1 and 2 represent a turning point in Beckett's career as a bilingual playwright. They are the last plays Beckett wrote in French, and, as their titles suggest, they remained unfinished. After the failure of the Roughs, Beckett's theatre evolved towards the very characteristic late plays. These were indubitably influenced by Beckett's incursion into the genres of radio and mime. For these later plays, English was the most appropriate language, for undeniable practical reasons, but also because these plays fit into the Irish theatrical tradition in ways in which the Roughs failed to.
Interaction Detection with Depth Sensing and Body Tracking Cameras in Physical Rehabilitation
Authors: Jansen B. , Bonnechère B. , Oravec M. , Jarmila P. , Jan S. Van Sint , Omelina L.
Published: December 2015

Introduction: This article is part of the Focus Theme of Methods of Information in Medicine on “Methodologies, Models and Algorithms for Patients Rehabilitation”. Objectives: This paper presents a camera based method for identifying the patient and detecting interactions between the patient and the therapist during therapy. Detecting interactions helps to discriminate between active and passive motion of the patient as well as to estimate the accuracy of the skeletal data. Methods: Continuous face recognition is used to detect, recognize and track the patient with other people in the scene (e.g. the therapist, or a clinician). We use a method based on local binary patterns (LBP). After identifying users in the scene we identify interactions between the patient and other people. We use a depth map/point cloud for estimating the distance between two people. Our method uses the association of depth regions to user identities and computes the minimal distance between the regions. Results: Our results show state-of-the-art performance of real-time face recognition using low-resolution images that is sufficient to use in adaptive systems. Our proposed approach for detecting interactions shows 91.9% overall recognition accuracy what is sufficient for applications in the context of serious games. We also discuss limitations of the proposed method as well as general limitations of using depth cameras for serious games. Conclusions: We introduced a new method for frame-by-frame automated identification of the patient and labeling reliable sequences of the patient’s data recorded during rehabilitation (games). Our method improves automated rehabilitation systems by detecting the identity of the patient as well as of the therapist and by detecting the distance between both over time.
A comparison of autogenous theories for the origin of eukaryotic cells
Authors: Baum David A.
Published: December 2015

PREMISE:

Eukaryotic cells have many unique features that all evolved on the stem lineage of living eukaryotes, making it difficult to reconstruct the order in which they accumulated. Nuclear endosymbiotic theories hold that three prokaryotes (nucleus, cytoplasm, and mitochondrion) came together to form a eukaryotic cell, whereas autogenous models hold that the nucleus and cytoplasm formed through evolutionary changes in a single prokaryotic lineage. Given several problems with nuclear endosymbiotic theories, this review focuses on autogenous models.

KEY INSIGHTS:

Until recently all autogenous models assumed an outside‐in (OI) topology, proposing that the nuclear envelope was formed from membrane‐bound vesicles within the original cell body. Buzz Baum and I recently proposed an inside‐out (IO) alternative, suggesting that the nucleus corresponds to the original cell body, with the cytoplasmic compartment deriving from extracellular protrusions. In this review, I show that OI and IO models are compatible with both mitochondria early (ME) or mitochondria late (ML) formulations. Whereas ME models allow that the relationship between mitochondria and host was mutualistic from the outset, ML models imply that the association began with predation or parasitism, becoming mutualistic later. In either case, the mutualistic interaction that eventually formed was probably syntrophic.

CONCLUSIONS:

Diverse features of eukaryotic cell biology align well with the IOME model, but it would be premature to rule out the OIME model. ML models require that phagocytosis, a complex and energy expensive process, evolved before mitochondria, which seems unlikely. Nonetheless, further research is needed, especially resolution of the phylogenetic affinities of mitochondria.
Fossil evidence for open, Proteaceae‐dominated heathlands and fire in the Late Cretaceous of Australia
Authors: Carpenter Raymond J. , Macphail Michael K. , Jordan Gregory J. , Hill Robert S.
Published: December 2015

PREMISE OF THE STUDY:

The origin of biomes is of great interest globally. Molecular phylogenetic and pollen evidence suggest that several plant lineages that now characterize open, burnt habitats of the sclerophyll biome, became established during the Late Cretaceous of Australia. However, whether this biome itself dates to that time is problematic, fundamentally because of the near‐absence of relevant, appropriately aged, terrestrial plant macro‐ or mesofossils.

METHODS:

We recovered, identified, and interpreted the ecological significance of fossil pollen, foliar and other remains from a section of core drilled in central Australia, which we dated as Late Campanian–Maastrichtian.

KEY RESULTS:

The sediments contain plant fossils that indicate nutrient‐limited, open, sclerophyllous vegetation and abundant charcoal as evidence of fire. Most interestingly, >30 pollen taxa and at least 12 foliage taxa are attributable to the important Gondwanan family Proteaceae, including several minute, amphistomatic, and sclerophyllous foliage forms consistent with subfamily Proteoideae. Microfossils, including an abundance of Sphagnales and other wetland taxa, provided strong evidence of a fenland setting. The local vegetation also included diverse Ericaceae and Liliales, as well as a range of ferns and gymnosperms.

CONCLUSIONS:

The fossils provide strong evidence in support of hypotheses of great antiquity for fire and open vegetation in Australia, point to extraordinary persistence of Proteaceae that are now emblematic of the Mediterranean‐type climate southwestern Australian biodiversity hotspot and raise the profile of open habitats as centers of ancient lineages.
Surfactant-controlled composition and crystal structure of manganese(II) sulfide nanocrystals prepared by solvothermal synthesis
Authors: Capetti Elena , Ferretti Anna M , Dal Santo Vladimiro , Ponti Alessandro
Published: December 2015

We investigated how the outcome of the solvothermal synthesis of manganese(II) sulfide (MnS) nanocrystals (NCs) is affected by the type and amount of long chain surfactant present in the reaction mixture. Prompted by a previous observation that a larger than stoichiometric amount of sulfur is required [Puglisi, A.; Mondini, S.; Cenedese, S.; Ferretti, A. M.; Santo, N.; Ponti A. Chem. Mater. 2010, 22, 2804–2813], we carried out a wide set of reactions using Mn(II) carboxylates and Mn2(CO)10 as precursors with varying amounts of sulfur and carboxylic acid. MnS NCs were obtained provided that the S/Mn ratio was larger than the L/Mn ratio, otherwise MnO NCs were produced. Since MnS can crystallize in three distinct phases (rock salt α-MnS, zincblende β-MnS, and wurtzite γ-MnS), we also investigated whether the surfactant affected the NC polymorphism. We found that MnS polymorphism can be controlled by appropriate selection of the surfactant. γ-MnS nanocrystals formed when a 1:2 mixture of long chain carboxylic acid and amine was used, irrespective of the presence of carboxylic acid as a free surfactant or ligand in the metal precursor. When we used a single surfactant (carboxylic acid, alcohol, thiol, amine), α-MnS nanocrystals were obtained. The peculiar role of the amine seems to be related to its basicity. The nanocrystals were characterized by TEM and electron diffraction; ATR-FTIR spectroscopy provided information about the surfactants adsorbed on the NCs.

La désobéissance comme principe de la démocratie
Authors: Laugier Sandra
Published: December 2015

Cet article examine les justifications de la désobéissance civile à partir d’un principe moral, qui n’est pas la liberté abstraite mais la confiance en soi  : elle encourage l’individu à refuser la loi commune et acceptée des autres, en se fondant sur sa propre conviction qu’elle est injuste et indigne. Loin de marquer un rejet ou une marge du politique, les actes de désobéissance en appellent à une extension des droits et des libertés qu’une démocratie devrait assurer à ses citoyens. On ne désobéit qu’en démocratie – quand on n’a plus dans la vie publique les conditions de la conversation où l’on pourrait raisonnablement exprimer son différend, quand on est dépossédé de sa voix. La désobéissance est alors un rappel du principe démocratie, qui est l’expression égale et inconditionnelle de chacun.
Fonctionnaire, obéir/désobéir
Authors: Chauvet Clément

Le droit de la fonction publique civile consacre un devoir d’obéissance solidement ancré, qui connaît des exceptions sous forme d’un devoir ou d’un droit de désobéissance. Le binôme « obéissance-désobéissance » montre cependant un certain nombre de paradoxes résultant d’une opposition entre deux impératifs contradictoires : protéger l’administration, le cas échéant contre la désobéissance ; protéger l’agent, éventuellement par l’obéissance à un ordre qui aurait dû être ignoré.

Authors: Ghali Zohra , Toukabri Maher
Published: December 2015

S’inscrivant dans une perspective relationnelle, l’objet de cette recherche est de mieux spécifier le lien causal entre les émotions ressenties dans un lieu visité et l’attachement à ce dernier tout en étudiant le rôle médiateur de l’immersion dans l’expérience de visite. Les résultats issus d’une enquête, menée auprès de 350 visiteurs de médina de Tunis, confirment la significativité du lien causal étudié et montrent que les émotions ressenties lors de visites de médina (plaisir, activation), renforcées par un état d’immersion vécu par le visiteur, permettent de développer une proximité psychologique et un attachement au lieu visité. Ces résultats permettent alors de suggérer des pistes d’amélioration aux professionnels du secteur touristique en Tunisie.

Published: December 2015

Experimental studies of production technological processes are now enabled through a use of the available simulation software. The scientific studies, executing experiments with simulation software, are used to optimize, improve efficiency, and elimination of deficiencies in manufacturing processes without any interfering with the real processes. The big advantage is that by using simulation software, one can simulate a number of experimental variations of scenarios in advance, and evaluate any intervention in the course of the active process. Experiments with a built simulation model answer the questions of what-if analysis for variable set scenarios.
Contact Problems between the Hub and the Shaft with a Four-Angular Shape of Cross-Section for Different Angular Positions
Authors: Dudziak Marian , Domek Grzegorz , Kołodziej Andrzej , Talaśka Krzysztof
Published: December 2015

The works [1, 2] present the values of the force and moment of friction needed to disassemble the axisymmetric connection with oval and three-angular shape of cross-section of the shaft. These works additionally show the variable values of the Mises stresses and contact pressures. This paper presents research which is a continuation of the research program on the evaluation of the influence of cross-section deviations, radial deviations, and their compilations on the value of the contact area in the connection. The limited contact area has a decisive impact on functional and operational parameters of the connection. Point contact between the shaft and the hole is the reason of the reduction of load transmission. The paper concerns the connection between the shaft with four-angular shape of cross-section with the deviation Tw = 13 μm and the hub with the nominal roudness. The authors have proved the occurrence of variable values of the force and moment of friction during disassembling of the connection. The authors have also showed the occurrence of variable values of the reduced stresses and contact pressures.

Published: December 2015

Abstract. The thermoacidophilic archaeon Metallosphaeracuprina was isolated from a sulfuric hot spring. M. cuprina is able to oxidize elemental sulfur, tetrathionate (S4O62+) pyrite, and a range of low-grade ores, thus is attractive to biomining industry. Dissimilatory sulfur metabolism with a sulfur oxygenase reductase (SOR) system has been reported for members of Sulfolobus and Acidianus. But SOR system was not identified in the genome of M. cuprina. Recently, we have explored the sulfur metabolism of M. cuprina with genomic, proteomic, and biochemical tools. A hypothetical model of sulfur metabolism in M. cuprina was proposed on proteomic and genomic data, and proteins that involved in sulfur metabolism have been identified in our following studies. Specifically, DsrE/TusA homologs were biochemically characterized, and a novel thiosulfate transfer reaction was found during sulfur oxidation with M. cuprina. More recently, we cloned and identified a CoA-dependent NAD(P)H sulfur oxidoreductase from M.cuprina. The study will cover new understandings of the sulfur metabolism with M. cuprina.

Río Tinto (Southwestern Spain, Iberian Pyrite Belt) is an unusual extreme environment with an unexpected level of eukaryotic microbial diversity. Of the different fungal strains isolated along the river over several years, one of them,Purpureocillium lilacinumM15001, is able to tolerate up to 1M Cu concentrations. This strain was able to remove 25% of the Cu when incubated at 50mM, 32% at 100mM and 51% at 500mM Cu concentrations. The amount of Cu detected inside the cells increased accordingly the concentration of Cu in the solution, from 8.2% of the total fungal dry weight at 50mM Cu concentration, to 13% when exposed to 100mM Cu and 22.4% at 500mM Cu. TEM studies showed the existence of electrodense material externally adsorbed to the fungal cell wall, as well as large intracellular deposits. EDX microanalyses revealed that this material was composed mainly of Cu. To clarify the possible resistance mechanisms involved in the tolerance of this fungal strain to Cu, a proteomic study has been carried out.
Effects of Ion Stress on the Oxidation Activity of Acidithiobacillus ferrooxidans
Authors: Dong Ying Bo , Lin Hai
Published: December 2015

The effects of stresses induced by four ions (potassium, magnesium, aluminum and fluoride ions) on the growth and activity ofAcidthiobacillus ferrooxidansLD-1 (At.fLD-1) were investigated. The results showed that these four ions inhibited the growth and activity ofAt.fLD-1 to different extents. The inhibition effect of these four ion stresses followed the order potassium < magnesium < aluminum < fluoride. The inhibition effects of the trivalent metal ion (aluminum) are greater than divalent (magnesium) and monovalent (potassium) ions at the same concentrations. The inhibition of cations onAt.fLD-1 was stronger than that of anions.

The effect of Sulfobacillus thermosulfidooxidans, cultured respectively in the substratum containing ferrous ion or solid elemental sulfur in a long term, on the leaching behavior of pyrrhotite was revealed through leaching test and surface analysis of pyrrhotite leaching residues using XRD and SEM. It was demonstrated that there was significant difference in growth characteristic of S. thermosulfidooxidans, the leaching behavior and surface products of pyrrhotite when pyrrhotite bioleaching was conducted using S. thermosulfidooxidans cultured in different mediums, and it suggested that the difference was chiefly due to different energy metabolism pathways. The pyrrhotite leaching behavior using S. thermosulfidooxidans grown on ferrous ion in a long term was similar to that in the sterile acidic system, and only leaching yield was slightly improved. This was attributed to the ability to oxidize sulfur of S. thermosulfidooxidans was weakened and thus the effect of the generated sulfur could not be eliminated, which leads to low iron extraction and low S. thermosulfidooxidans reproduced ability for lack of growth energy. In the case of S. thermosulfidooxidans cultured in medium containing sulfur, The ability to oxidize sulfur was enhanced, the bacterium grew rapidly in the mid-term of leaching, which weakened the suppressing effect of sulfur film and improved significantly pyrrhotite leaching. However, a large number of jarosite was generated owing to the accumulation of ferric ions with the bioleaching processing, and the formed wrapping layer by jarosite and minor sulfur on mineral surface suppressed further leaching of pyrrhotite.

The methods of biodegradation are of special interest because they help solving environmental problems of wastes detoxification from gold-mining operations. The use of bacterial strains is a promising approach in the field of biotechnology to destruct cyanide-bearing compounds. The diversity of microbial communities both in heap in situ and in the enriched cultures was studied with molecular genetic methods. The differences in representation of bacteria, cultivated in unexploitable and operating heaps, are territory, site and heap specific. The strains of Pseudomonas sp. and Methylobacterium sp. possess the biotechnological potential and might be used in biodegradation of heap leaching wastes in extreme continental climate.
Geobiotechnical Recovery of Metals from Manganese Nodules: First Experiments
Authors: Heller Christina , Schippers Axel
Published: December 2015

Marine polymetallic nodules represent an important resource of the metals Ni, Co, Cu, Mn, Zn, Li, Mo, V and Zr. Nodules consist mainly of Mn-Fe oxy-hydroxide precipitations with valuable metals mostly present within the structure of these host minerals. To recover the favoured metals via hydrometallurgy it is necessary to dissolve the Mn-Fe oxy-hydroxides. To test nodules processing via bioleaching, nodules were sampled during a ship cruise to the German license area located in the Pacific Ocean in 2013. They were ground in a mortar, washed to remove seawater chloride, and afterwards sieved to obtain the particle size fraction of 63 to 315 µm. Bioleaching experiments were conducted under aerobic conditions in shake flasks at 2 % pulp density at 30°C in a basal medium. A mixed culture of acidophilic chemolithotrophic iron- and sulfur-oxidizing bacteria (Acidithiobacillus thiooxidans, At. ferrooxidans, Leptospirillum ferrooxidans, L. ferriphilum) and Acidiphilum cryptum was inoculated. Elemental sulfur was used as substrate for acid leaching via sulfuric acid production. At pH values between 1.5 and 2.2 during the experiment, 40 % Ni, 25 % Cu, 1.2 % Mn, 0.3 % Co, 1 % Fe, 70 % Zn and 70 % Zr were leached from the Mn-nodules after 56 days. In preparation for future reductive bioleaching under anaerobic conditions, chemical kinetic reaction experiments were conducted. Different amounts of Fe(II) were added to a certain amount of the Mn nodules. These experiments showed that Fe(II) chemically reduced Mn(IV) to Mn(II) at a stoichiometry of 2 to 1. This reaction is prerequisite for anaerobic leaching based on biological reduction of Fe(III) to Fe(II) coupled to sulfur oxidation (Ferredox process). Up to 82 % Ni, 98 % Co, 68 % Cu, and 97 % Mn were leached in these chemical experiments indicating that anaerobic reductive bioleaching of manganese nodules should be possible.

Published: December 2015

The effect of solvent extractants, such as M5774, Cyanex 272, P204, P507 and N235, on the activity and community structure of acidophilic microorganisms were tested. Cobalt extractant Cyanex 272 did not show much inhibition effect on the growth of acidophiles, while iron extractant N235 had great inhibition effect. When the culture solution contacted with iron extractant P204, nickel extractant P507 and copper extractant M5774, the inhibition effect increased gradually. 16S rRNA gene clone library were used to analyze the initial and extractant contacted final microbial community structure. The initial inoculation microbial populations were mainly composed by Leptospirillum ferriphilum and Acidithiobacillus ferrooxidans. After cultivated in solution containing extractant M5774, Cyanex 272, P204 and P507, the number of the two species decreased, while heterophilic Acidiphilium cryptum became the dominant population. When cultured by M5774 and Cyanex 272, the proportion of Acidithiobacillus ferrooxidans was higher than Leptospirillum ferriphilum, while when cultivated by P204 and P507, the number of Leptospirillum ferriphilum was higher.

Authors: Bulaev Aleksander
Published: December 2015

The ferrous iron oxidation by mixed culture of moderately thermophilic microorganisms (Sulfobacillus thermosulfidooxidansSh 10-1 andAcidiplasmaMBA-1) was investigated in continuous experiments in three packed-bed reactors connected in series at temperature 55°C, and a pH of 1.0. Two solutions were used in the experiments. The first one contained (g L-1) 59 Fe2+, the second one contained (g L-1) 59 Fe2+, 16 Fe3+, 2 Cu2+, 2 Zn2+. The hydraulic retention time was 120 hours. Iron oxidation rates in the experiment with the first solution were 0.5, 0.35, and 0.2 g L-1h-1in first, second and third reactor, respectively. The oxidation rates in the experiment with the second solution were 0.3, 0.2, and 0.185 g L-1h-1in first, second and third reactor, respectively. Iron oxidation efficiencies in the experiments with the first and second solutions were 77% and 47%. Stable continuous iron oxidation at high temperature was successfully demonstrated, but further investigations are required for improving the rate and efficiencies of oxidation.
