Jean Genet – pudique ou impudique ? Les traductions norvégienne et américaine de Journal du voleur
Authors: Uvsløkk Geir
Published: June 2014

La traduction norvégienne de Journal du voleur de Jean Genet (1948/1949) semble plus pudique que l’édition française courante, tandis que la traduction américaine semble plus impudique. Le traducteur norvégien a légèrement modifié le texte afin d’échapper à la censure norvégienne, tandis que le traducteur américain a basé sa traduction sur la première édition de Journal du voleur, presque introuvable en France aujourd’hui, et qui est encore plus provoquante que l’édition courante. Les choix des traducteurs sont liés à leur connaissance de l’oeuvre de Genet et à leur conscience des pratiques de la censure dans le(s) pays de la langue-cible.
Le français et le roumain – égo/égaux devant la pudeur ?!
Authors: Coiug Ana , Pelea Alina
Published: June 2014

Une observation plutôt amusante au début concernant le contraste évident entre l’audace française et la timidité roumaine a stimulé les auteures de cet article à s’interroger un peu plus à ce sujet et à examiner les implications que peut avoir en traduction la pudeur intrinsèque d’une langue (ou, au contraire, son manque de pudeur). Pour répondre à leurs questionnements, les auteures ont analysé cette asymétrie entre le roumain et le français à la lumière de réflexions de traducteurs, de traductologues et d’autres spécialistes de la langue.

The reported IgG seroprevalence against hepatitis E virus (HEV) in German blood donations is 6.8%, and HEV RNA detected in 0.08%, but documented evidence for HEV transmission is lacking. We identified two donations from a single donor containing 120 IU HEV RNA/mL plasma and 490 IU/mL. An infectious dose of 7,056 IU HEV RNA was transmitted via apheresis platelets to an immunosuppressed patient who developed chronic HEV. Further, transmission was probable in an immunocompetent child.
Microstructure and Compressive Properties of Open-Cell Silver Foams with Different Pore Architectures
Authors: Asavavisithchai Seksak , Preuksarattanawut Thanachache , Nisaratanaporn Ekasit
Published: June 2014

Hollow silver particles with three different shapes, i. e., spherical, cylindrical, and octahedral, were used as raw material to produce open-cell silver foams. The shape difference of the particles resulted from the reduction of different shaped silver sulfates. Fabrication of silver foams was carried out using SDP process with disaccharide particles as space holder. The resultant silver foams show high porosity with distinctive pore microstructures. The examination of pore structure by SEM shows that there are three levels of porosities which are unique for each type of foam. The foams, using spherical and cylindrical silver particles, have a larger surface area and a higher density than the foam with the silver particle of octahedral shape. A control of pore architecture can be performed by tailoring material and process parameters. The difference in pore architecture resulted in a different compressive behaviour of the foams. As expected, the foam, using octahedral silver particles, has lower compressive strength than the others, mostly due to lower foam density.

Authors: Ambarkutuk Aysin , Daglilar Sibel
Published: June 2014

AlTiC master alloys were improved greatly and used as a new type in grain refinement of aluminum and aluminum alloys. In the present work, Al-Ti-C grain refiners with different Ti/C ratios were in-situ produced by the addition of K2TiF6 and elemental carbon powder mixture to the commercial pure aluminum. The effects of casting temperature and Ti/C ratio on the grain refinement process were investigated by the so-called Alcoa Cold Finger test and respective optimum conditions were determined. The results indicate that the produced Al-Ti-C master alloys contain TiC and TiAl3 particles within the aluminum matrix. The proper conditions for evaluating the efficiency of the produced Al-Ti-C master alloy to obtain a minimum grain size are: Temperature of 1300 °C, holding time of 20 minutes, and a Ti/C 0.60 wt.-%
Effect and Optimization of Resistance Spot Welding Parameters on the Strength of Welded Hot-Stamped Parts
Authors: Önal Ahmet Serdar , Kaya Necmettin
Published: June 2014

In this study, the effects of three control parameters for the resistance spot welding of hot-stamped parts were studied. These control parameters are the welding force, welding time, and welding current. Al-Si coated 22MnB5 (USIBOR 1500P) sheets with thicknesses of 1.7 mm and 2 mm were used for the experiments. The Taguchi L9 orthogonal array was used in the experiments. Evaluation of the experiments was based on the shear strengths of the welded specimens. The higher is better equation was selected to analyze the results. The relative importance of the spot welding parameters and their optimal combinations were determined using ANOVA. Additionally, an optimization of the welding parameters to maximize the weld tensile shear was conducted using the differential evolution algorithm, as well as the optimal parameters were determined.

Authors: Rong Zhen , Chen Fang , Liu Hong
Published: June 2014

In this work, the particle image velocimetry (PIV) technique was applied to study the compressible supersonic flow regimes in the multi-Mach number high-speed (MMH) wind tunnel. To generate sufficient light scattering and flow across shock waves, tracer particles and the seeding technique were used, as well as scattering and tracking of particles were investigated using experimental observations and theoretical analysis. It was determined that the actual particle diameter should be around 200 nm to guarantee an adequate aerodynamic response to velocity gradients in the flow. It was further shown by the PIV measurements over a sharp cone that the uniformity of seeding particles dispersion was very important for the operations of the seeding facility. The present study indicated that the PIV technique could be an efficient method for monitoring the flow field of shock wave and subsonic flow regimes.

Published: June 2014

In order to study the effect of Mo on the microstructure, mechanical properties and corrosion behavior of commercially pure titanium (cp-Ti), Ti-xMo (x = 5, 10, 15, and 20 wt.%) alloys were investigated. The phase and microstructures were characterized using X-ray diffraction, optical microscopy, scanning electron microscopy and transmission electron microscopy. The results indicated that the Ti-5Mo alloy was mainly composed of α′ phase with a small fraction of α″ phase. The Ti-10Mo was dominated by orthorhombic α″. The Ti-15Mo alloy was mainly composed of α″ phase with a small fraction of β phase. The volume percentage of the β phase increased with increasing Mo content. The Ti-20Mo alloy was mainly composed of β phase. We also investigated the effect of alloying with Mo on the Vickers hardness and corrosion behavior of Ti-xMo alloys. The addition of Mo not only caused hardening of cp-Ti but also improved its oxidation protective ability. Electrochemical results showed that the Ti-xMo alloys exhibited improved corrosion resistance over cp-Ti.

Published: June 2014

The aim was to determine the effect of extrusion process parameters of the KoBo method (initial billet temperature, extrusion rate and die oscillation frequency) on the Lüders phenomenon occurrence in aluminum wires.

The material used in the experiment was 99.7% pure Al billet. The extrusion was carried out with the following parameters: extrusion ratio λ = 100, initial billet temperature in the range of 293–493 K, extrusion rate of 0.1–0.5 mm · s−1 and frequencies of 3, 5 and 8 Hz (the die oscillation angle was a constant ± 8°). Output materials were mechanically tested and examined microscopically. Based on the results it was found that: the Lüders phenomenon in aluminum wires extruded by the KoBo method appears only i) in a specific range of the extrusion force, namely 450–650 kN, ii) a specific range of, yielding strength (100–140 MPa), iii) dependent on the combination of process parameters its extent and position can vary over a product's length, iv) tests have also shown that this phenomenon has a continuous propagation nature only at the initial stage of the tensile test.
Effects of copper content and liquid separation on the microstructure formation of Co–Cu immiscible alloys
Authors: Yang Wei , Zhang Yan Long , He Wen , Xu Zhi Feng
Published: June 2014

Applying a melt-fluxing method combined with cyclical superheating, rapid solidification of undercooled Co70Cu30, Co50Cu50 and Co30Cu70 melts was performed to investigate the effects of alloy composition and immiscibility on the resultant non-equilibrium solidification microstructure. As for the samples without liquid separation, grain refinement of primary α-Co dendrite occurs clearly with increases in both copper content and initial undercooling. In contrast, the influence of alloy composition on microstructure evolution is weakened due to the occurrence of liquid separation at larger undercooling, where slight variations in the solute concentration and micro-hardness for Co-rich phase are obtained. After a quantitative thermodynamic calculation, the process of liquid separation is described, which gives an excellent explanation for the observed experimental results.
Does the Threat of European Pine Marten (Martes Martes) Predation Influence the Height of Nests Built by Blue Tits (Cyanistes Caeruleus) and Great Tits (Parus Major)?
Authors: Kaliński Adam , Wawrzyniak Jarosław , Bańbura Mirosława , Skwarska Joanna , Zieliński Piotr , Glądalski Michał , Bańbura Jerzy
Published: June 2014

The major aim of this study was to examine the influence of the European Pine Marten ( Martes martes) predation on the heights of nests of Blue Tits ( Cyanistes caeruleus) and Great Tits ( Parus major) in nestboxes of different security levels. To this end we performed a comparison of nest heights before and after introducing an anti-predator device to two size-types of wooden nestboxes set up in a deciduous forest. Blue Tit and Great Tit nest sizes were influenced by the application of plastic entrance tubes as anti-predator devices that elongated a distance between the entrance and the interior of the nestbox. Nests were taller in nestboxes equipped with anti-predator devices regardless of nestbox size. Nests located in smaller nestboxes were destroyed by Martens more frequently than nests built in bigger nest boxes. Most nest functions in cavity-nesting birds, such as filling the excessive cavity space, maintenance of proper humidity, thermal, light and sanitary conditions for eggs and nestlings, improve with nest sizes. Because, in contrast, the risk of nest predation by martens increases with nest size (height within the nestbox), the nest predation constitute a major factor that constrains cavity-nesting birds in constructing tall nests.
Isolation and Characterisation of Microsatellites in the Genome of Alectoris Rufa
Authors: Ansón J. A. , Savva D. , Arruga M. V.
Published: June 2014

Since the introduction of Alectoris chukar in Spain, hybridisation has occurred in the wild and on farms with the native A. rufa but the native species is phenotypically indistinguishable from the hybrid partridges. In order to provide tools for the identification of the native and hybrid birds a partridge genomic library was constructed using the plasmid pSMART-HCKan and Escherichia cloni 10G bacterial cells. DNA from bacteria containing recombinant plasmids was transferred onto nylon hybridisation membranes in order to screen for plasmids containing (AC)13 and (AG)13 which are the most common dinucleotide repeats in the avian genome. DNA hybridisation was performed using (AC)13 and (AG)13 probes labelled with the TexasRed and fluorescein fluorochromes and hybridisation was detected using a fluorescence microscope. Two microsatellites were identified in non-coding regions of the partridge genome and these have been used to characterise a number of A. rufa individuals from different parts of Europe.

Published: June 2014

The potential for future dynamical instability of Pine Island Glacier, West Antarctica, has been addressed in a number of studies, but information on its past remains limited. In this study we use airborne radio-echo sounding (RES) data acquired over Pine Island Glacier to investigate past variations in accumulation pattern. In the dataset a distinctive pattern of layers was identified in the central part of the glacier basin. We use these layers as chronological identifiers in order to construct elevation maps of the internal stratigraphy. The observed internal layer stratigraphy is then compared to calculated stratigraphy from a three-dimensional ice-flow model that has been forced with different accumulation scenarios. The model results indicate that the accumulation pattern is likely to have changed at least twice since the deposition of the deepest identified layer. Additional RES data linked to the Byrd ice core provide an approximate timescale. This timescale suggests that the layers were deposited at the beginning of or during the Holocene period. Thus the widespread changes occurring in the coastal extent of the West Antarctic ice sheet at the end of the last glacial period could have been accompanied by changes in accumulation pattern.

Authors: Kido Yuya , Sakai Reika , John Baiju , Okamoto Masami , Seppälä Jukka
Published: June 2014

To understand the enzymatic degradation behavior of crosslinked polylactide (PLA), the preparation and enzymatic degradation of both thermoplastic (linear) and crosslinked PLAs that have pore structures with different dimensions were carried out. The porous structures of the linear PLA samples were of micro and nanoporous nature, and prepared by batch foaming with supercritical CO2 and compared with the porous structures of crosslinked PLA (Lait-X) created by the salt leaching method. The surface and cross-sectional morphologies of the porous structures were investigated by using scanning electron microscopy. The morphological analysis of porous Lait-X showed a rapid loss of physical features within 120 h of exposure to proteinase-K enzymatic degradation at 37 °C. Due to the higher affinity for water, enhanced enzymatic activity as compared to the linear PLA porous structures in the micro and nanoporous range was observed.

Published: June 2014

Metabolomics and genomics are two complementary platforms for analyzing an organism as they provide information on the phenotype and genotype, respectively. These two techniques were applied in the dereplication and identification of bioactive compounds from a Streptomyces sp. (SM8) isolated from the sponge Haliclona simulans from Irish waters. Streptomyces strain SM8 extracts showed antibacterial and antifungal activity. NMR analysis of the active fractions proved that hydroxylated saturated fatty acids were the major components present in the antibacterial fractions. Antimycin compounds were initially putatively identified in the antifungal fractions using LC-Orbitrap. Their presence was later confirmed by comparison to a standard. Genomic analysis of Streptomyces sp. SM8 revealed the presence of multiple secondary metabolism gene clusters, including a gene cluster for the biosynthesis of the antifungal antimycin family of compounds. The antimycin gene cluster of Streptomyces sp. SM8 was inactivated by disruption of the antimycin biosynthesis gene antC. Extracts from this mutant strain showed loss of antimycin production and significantly less antifungal activity than the wild-type strain. Three butenolides, 4,10-dihydroxy-10-methyl-dodec-2-en-1,4-olide (1), 4,11-dihydroxy-10-methyl-dodec-2-en-1,4-olide (2), and 4-hydroxy-10-methyl-11-oxo-dodec-2-en-1,4-olide (3) that had previously been reported from marine Streptomyces species were also isolated from SM8. Comparison of the extracts of Streptomyces strain SM8 and its host sponge, H. simulans, using LC-Orbitrap revealed the presence of metabolites common to both extracts, providing direct evidence linking sponge metabolites to a specific microbial symbiont.
The Tumor-Associated Marker, PVRL4 (Nectin-4), Is the Epithelial Receptor for Morbilliviruses
Authors: Delpeut Sebastien , Noyce Ryan , Richardson Christopher
Published: June 2014

PVRL4 (nectin-4) was recently identified as the epithelial receptor for members of the Morbillivirus genus, including measles virus, canine distemper virus and peste des petits ruminants virus. Here, we describe the role of PVRL4 in morbillivirus pathogenesis and its promising use in cancer therapies. This discovery establishes a new paradigm for the spread of virus from lymphocytes to airway epithelial cells and its subsequent release into the environment. Measles virus vaccine strains have emerged as a promising oncolytic platform for cancer therapy in the last ten years. Given that PVRL4 is a well-known tumor-associated marker for several adenocarcinoma (lung, breast and ovary), the measles virus could potentially be used to specifically target, infect and destroy cancers expressing PVRL4.
Ghd7 (Ma6) Represses Sorghum Flowering in Long Days: Ghd7 Alleles Enhance Biomass Accumulation and Grain Production
Authors: Murphy Rebecca L. , Morishige Daryl T. , Brady Jeff A. , Rooney William L. , Yang Shanshan , Klein Patricia E. , Mullet John E.
Published: June 2014

Sorghum Ma6, a strong repressor of flowering in long days (LDs), was identified as the CONSTANS, CO‐like, and TOC1 (CCT)‐domain protein encoded by SbGhd7. Sorghum Ghd7 increases photoperiod sensitivity and delays flowering by inhibiting expression of the floral activator SbEhd1 and genes encoding FT. SbGhd7 expression is light‐dependent and gated by the circadian clock. In LDs when flowering is repressed, SbGhd7 mRNA abundance peaks in the morning and evening. In short days (SDs) when floral initiation occurs, the evening phase of SbGhd7 expression occurs in darkness, reducing SbGhd7 mRNA abundance. In energy sorghum hybrids, dominant alleles of SbGhd7 and SbPRR37 act in additive fashion to delay floral initiation for ∼175 d until daylengths decrease below 12.3 h. In contrast, photoperiod‐insensitive grain sorghum genotypes containing recessive alleles of SbGhd7 and SbPRR37 flower in 60 to 80 d. Recessive alleles of SbGhd7 and SbPRR37 are present in historically important sorghum germplasm introduced into the United States in the 1800s that was used to produce early flowering grain and sweet sorghum. Recessive alleles ghd7‐1 and prr37‐1 are present in maturity standards such as SM100, and in BTx406, a genotype used in the Sorghum Conversion Program to convert late‐flowering photoperiod‐sensitive sorghum accessions into early flowering photoperiod‐insensitive germplasm useful for grain sorghum breeding. The results show that alleles of SbGhd7 confer differences in photoperiod sensitivity and flowering times that are critical for production of late‐flowering high‐biomass energy sorghum and early flowering grain sorghum.
A Population-based Study Showing Better Renal Prognosis for Proteinase 3 Antineutrophil Cytoplasmic Antibody (ANCA)–associated Nephritis Versus Myeloperoxidase ANCA–associated Nephritis
Authors: Mohammad Aladdin J. , Segelmark Mårten
Published: June 2014

Objective.

Antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) is usually differentiated based on clinical phenotypes, but recent data indicate that myeloperoxidase (MPO)-AAV is genetically distinct from proteinase 3 (PR3)-AAV. We reviewed a population-based cohort of AAV, focusing on differences in clinical and laboratory characteristics and to compare renal outcome between MPO-ANCA and PR3-ANCA nephritis.

Methods.

All new cases of AAV diagnosed between 1997 and 2009 in a geographically defined area in southern Sweden were retrieved using a validated search algorithm. Data were collected from time of diagnosis and end of followup. Renal and patient survival were analyzed according to ANCA serotype.

Results.

During the study period, 201 patients were diagnosed with AAV, 98 tested positive for PR3-ANCA, and 85 for MPO-ANCA. Patients with PR3-ANCA were younger, had significantly higher inflammatory activity, and had a larger number of organs involved at diagnosis, but nephritis was more prevalent among patients with MPO-associated (72/85; 85%) versus PR3-associated disease (67/98, 68%). When comparing only patients with ANCA-associated nephritis, those with MPO-ANCA were more likely to develop endstage renal disease (n = 27, 38%) than those with PR3-ANCA (n = 10, 15%), p = 0.003. The risk remained significantly elevated after adjusting for sex, age, and s-creatinine level at diagnosis (HR 2.64; 95% CI 1.25–5.58; p = 0.003). There were no significant differences in mortality rates between the 2 groups.

Conclusion.

The outcome in this population-based cohort indicates that among AAV patients with nephritis, renal prognosis is better in the PR3-ANCA group, even after adjustment for sex, age, and renal function at diagnosis.
Risk Factors for Drug-resistant Bloodstream Infections in Patients with Systemic Lupus Erythematosus
Authors: Barrera-Vargas Ana , Gómez-Martín Diana , Merayo-Chalico Javier , Ponce-de-León Alfredo , Alcocer-Varela Jorge
Published: June 2014

Objective.

To identify risk factors for developing drug-resistant bacterial infections in patients with systemic lupus erythematosus (SLE).

Methods.

A retrospective, case-control study was performed. Patients fulfilled American College of Rheumatology criteria for SLE and had an episode of bloodstream infection between 2001 and 2012. Cases were defined as those with bloodstream infection caused by drug-resistant bacteria (Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus, or extended-spectrum-β-lactalamase-producing Escherichia coli); while controls had susceptible strains of S. aureus or E. coli. Differences between groups were analyzed by Student t test or Mann-Whitney U test. Association between variables was assessed by OR (CI 95%). Multivariate analysis was performed by binary logistic regression model.

Results.

Forty-four patients were included in each group. Variables associated with drug-resistant bloodstream infection were history of central nervous system activity; hematological activity, immunosuppressive treatment and prednisone dose at the time of the infection; and low C3 levels, antibiotic use, or hospitalization in the previous 3 months. In multivariate analysis, variables that remained significant were low C3 previous to infection (OR 3.12, CI 95% 1.91–8.22), previous hospitalization (OR 2.22, CI 95% 1.42–4.10), and prednisone dose at the time of infection (OR 1.10, CI 95% 1.04–1.22).

Conclusion.

Low C3 levels, recent hospitalization, and prednisone dose at time of infection are independent risk factors for acquiring drug-resistant bacteria in patients with SLE. Although the present data do not fully support a change in initial treatment-decision strategies, this information could lead to prospective studies designed to address this issue, which could determine the best approach in clinical practice.
A Metaanalysis of the Increased Risk of Rheumatoid Arthritis-related Pulmonary Disease as a Result of Serum Anticitrullinated Protein Antibody Positivity
Authors: Zhu Junqing , Zhou Yi , Chen Xiaoguang , Li Juan
Published: June 2014

Objective.

An inconsistent association has been reported between the serum anticitrullinated protein antibodies (ACPA) level and rheumatoid arthritis (RA)-related pulmonary disease risk. We conducted a metaanalysis to reveal the association between them.

Methods.

An electronic search was performed in PubMed, ScienceDirect, and SpringerLink databases for studies published up to August 2013. The distributions of the serum ACPA level in cases and controls were obtained from eligible studies. The risk of RA-related pulmonary disease associated with serum ACPA positivity was estimated by OR and 95% CI. According to the heterogeneity results, a fixed-effects model or a random-effects model was used to calculate the pooled OR. Publication bias and sensitivity analyses were conducted.

Results.

Overall, 243 patients with RA-related pulmonary disease and 1442 RA controls were included in the metaanalysis. The results showed that the pooled OR was 2.621 (95% CI, 1.561–4.403, p < 0.001) for the increased risk of RA-related pulmonary disease due to the serum ACPA positivity. In the white population subgroup, an increased OR was 3.453 (95% CI 1.798–6.630, p < 0.001), whereas no association was found in the Asian population subgroup. Additionally, we further revealed that serum ACPA positivity indicated a higher risk for interstitial lung disease (ILD) and interstitial pulmonary fibrosis (IPF) among patients with RA (OR 4.679, 95% CI 2.071–10.572, p < 0.001). The heterogeneity, publication bias, and sensitivity analyses had no statistical significance in any group.

Conclusion.

To our knowledge, this is the first metaanalysis to reveal that serum ACPA positivity is highly associated with the risk of RA-related pulmonary disease, particularly in RA-related ILD and IPF.

Species composition and structure of a photophilic algal community dominated by Halopteris scoparia (L.) Sauvageau from the North-Western Mediterranean
Authors: Ballesteros Enric
Published: June 2014

Se describe una comunidad de algas fotófilas mediterráneas de modo calmado dominada por Hatopteris scoparia y otros feófitos de porte mediano, la cual se adscribe a la asociación Padino-Clodostephetum hirsutae J. Feldmann 1937. Dicha asociación se caracteriza por la ausencia de un estrato elevado de Fucales y el escaso grado de presencia de especies termófilas propia de comunidades similares descritas de otras zonas del Mediterráneo. La biomasa algal oscila entre 1100 y 2500 g ps m-2 mientras que el porcentaje de recubrimiento varía entre el 250 y el 450%. Se pone de manifiesto la gran miniaturización de las comunidades de algas fotólitas mediterráneas y su extraordinaria diversidad y riqueza especificas. Pese a no existir un claro cambio estacional de biomasa en la especie dominante, es posible distinguir la existencia de dos estadios estructurales en la comunidad a lo largo del año: un estadio de comunidad desarrollada (verano) y un estadio de comunidad diversificada (invierno). Finalmente se compara la estructura de la comunidad y los factores ambientales a los que está sometida con los descritos para otras comunidades mediterráneas similares.
