A one-pot synthesis of Ag/α-Fe2O3 nanoplates with gelatin and their photocatalytic activity
Authors: Zhang Danhui , Yang Houbo 
Published: July 2013

Abstract
Ag/α-Fe2O3 nanoplates with a size range of 40–60 nm were fabricated by means of a facile gelatin assisted hydrothermal technique. The samples were characterized using X-ray diffraction, transmission electron microscopy, and UV-vis spectroscopy. The results demonstrate that these composites consist of silver and hematite (α-Fe2O3) and the band gap of the Ag/α-Fe2O3 composite is much narrower than for the pure α-Fe2O3. Furthermore, the photocatalysis test shows that the Ag/α-Fe2O3 composite exhibits a higher photocatalytic activity than the pure α-Fe2O3 nanoplates, thereby implying that the Ag/α-Fe2O3 interfaces promote the separation of photogenerated electron–hole pairs and enhance the photocatalytic activity.
Research on the creep fracture mechanism of FGH95 Ni-based superalloy
Authors: Jun Xie , Sugui Tian , Xiaoming Zhou , Yong Su , Jiao Liu 
Published: July 2013

Abstract
The creep fracture mechanism of FGH95 superalloy has been investigated by means of microstructure observation and creep behaviour measurement. Results show that, after solution treatment at 1150°C, the coarser γ′ precipitates distribute in the wider regions of previous particle boundaries. As the solution temperature increases to 1165°C, the grains grow in the alloy and carbide films precipitate along the grain boundaries. When the alloy is solution treated at 1160°C, the coarser γ′ phase in boundary regions is fully dissolved, and granular carbides precipitate along the grain boundaries, which may effectively restrain boundary sliding and hinder dislocation movements to improve the creep resistance of the alloy. During creep, the deformation feature of the alloy is that slipping dislocations with single or double orientations and stacking faults are activated in the alloy. As creep progresses, the amount of slip traces increases to bring about stress concentration and cause microcracks to be initiated and propagated along the grain boundaries up to the rupture of the alloy.
La possession de Loudun (1632-1637)
Authors: Houdard Sophie 
Published: July 2013

Les écrits de la possession en France au xvii e siècle ont souvent été travaillés par les historiens spécialistes des religions et de l’irréligion. Cet article se propose de voir en quoi l’apport de l’anthropologie, rarement mise à contribution dans le cas de la possession européenne de l’époque moderne, offrirait de nouveaux éclairages sur la possession de Loudun (1632-1637). Ce sont surtout les notions de « performance » et de « drame social », empruntées à Richard Schechner et Victor Turner, qui seront ici mises en usage. Nous verrons de quelle manière elles peuvent ouvrir de nouvelles pistes d’étude et de nouveaux points de vue sur la possédée, considérée alors comme actrice du processus social de la possession.
Le Web des troubles alimentaires. Un nouvel art de jeûner ?
Authors: Casilli Antonio 
Published: July 2013

Le phénomène contemporain des sites web « pro-ana » (ou, plus exactement, « ana-mia »), consacrés aux échanges autour des troubles des conduites alimentaires et tout particulièrement de l’anorexie mentale, réinterroge les catégories de corps, de présence et de performativité. Via leurs textes, vidéos, images, les contributeurs de ces blogs et forums documentent leurs gestes quotidiens, leurs sensibilités esthétiques. Face à la stigmatisation par l’opinion publique, leurs postures se radicalisent, se chargent de colorations héroïques, et ne se laissent plus exprimer que par un vocabulaire de citoyenneté : « choix », « liberté », « droit » d’être anorexique. Le rapport du performeur en ligne à son public s’avère principalement régi par une intention politique de recherche d’entraide et d’autonomie. L’art de jeûner, dessiné par Kafka dans le récit « Ein Hungerkünstler », se transforme alors dans un effort collectif de vigilance et de négociation autour des limites de la performativité du corps dans les environnements numériques, et dans le contexte élargi de la vie publique.
L'« événement-spectacle »
Authors: Spielmann Guy 
Published: July 2013

Depuis les années 1950 s’est développé dans les pays anglophones un vaste champ de recherche et d’enseignement autour de la notion de « performance ». Bien que la masse imposante de travaux publiés depuis un demi-siècle, encore très partiellement diffusée hors de l’aire culturelle anglo-américaine, puisse induire à croire que le domaine est aujourd’hui parfaitement balisé, il lui manque encore un objet scientifique bien défini, la performance étant envisagée de manières extrêmement diverses par les théoriciens, qui s’accommodent des divergences au nom de la pluralité. Or, en termes pratiques, la performance ne trouve sa raison d’être qu’en complémentarité avec la spectation, lorsque l’une et l’autre se produisent en un lieu et à un moment donnés. C’est donc cette instance particulière, l’« événement-spectacle », qui apparaît désormais comme le légitime objet scientifique d’un champ de recherche qui dépasse les apories propres aux « études théâtrales » et aux Performance Studies .
MIMO-OFDM Systems Performance Enhancement Based Peaks Detection Algorithm
Authors: Daoud Omar , Hamarsheh Qadri , Al-Sawalmeh Wael 
Published: July 2013

This work proposes a new algorithm to enhance the performance of the speaker verification over the communication systems based Multiple-Input Multiple-Output (MIMO) - Orthogonal Frequency Division Multiplexing (OFDM) techniques. The algorithm mainly tackles and overcomes the effect of the high Peak-to-Average Power Ratio problem that is found in OFDM systems, MIMO-OFDM combination has been developed to meet the rapidly increment in the users demand such as the ubiquitous transmission, imposing new multimedia applications and wireless services. In this algorithm, wavelets techniques have been used to denoise the affected OFDM symbol by high PAPR values. After that and based on adaptive threshold method the local maxima and minima will be determined and replaced by the average of them and their surrounding neighbors; Denoise OFDM and Replace PAPR (DORP).
A system performance investigation process will be accomplished based on both of numerical method and MATLAB simulation. Moreover, a comparison has been made to check the validity of our proposition either with our previously published work or with the literature. Although, the achieved results show that the proposed work has lower PAPR values; an additional complexity has been added to transceiverâ??s structure. Moreover, and as a result to the comparison with the conventional systems, the bit error rate (BER) performance has been improved for the same bandwidth occupancy.
As a validity process a comparison has been made with the current values found in the literature and we have achieved around 30% PAPR extra reduction. That is in addition to around 90% verification rate and noise immunity.
Fungal symbiont of firebrats (Thysanura) induces arrestment behaviour of firebrats and giant silverfish but not common silverfish
Authors: Woodbury Nathan , Gries Gerhard 
Published: July 2013

AbstractWe have recently shown that firebrats, Thermobia domestica (Packard) (Thysanura: Lepismatidae), carry, and deposit with their faeces, the symbiotic bacterium Enterobacter cloacae (Jordan 1890) Hormaeche and Edwards 1960 (Enterobacteriaceae) and the symbiotic fungus Mycotypha microspora Fenner, 1932 (Mycotyphaceae), and that these microbes induce arrestment behaviour and aggregation of firebrats. Here, we tested whether giant silverfish, Ctenolepisma longicaudata Escherich (Thysanura: Lepismatidae), and common silverfish, Lepisma saccharina (Linnaeus) (Thysanura: Lepismatidae), also arrest in response to these two microbes. In dual-choice bioassays, E. cloacae arrested firebrats but not giant silverfish or common silverfish, whereas M. microspora arrested firebrats and giant silverfish but not common silverfish. As close relatives, firebrats and giant silverfish have similar microclimate and nutrient requirements and may use M. microspora as the same aggregation cue when they aggregate in hot and humid microclimates where M. microspora proliferates and breaks down cellulose. As a more distant relative to firebrats and giant silverfish, common silverfish seem to require a different as yet unknown aggregation cue or signal, possibly one that is indicative of the type of microclimate (room temperature; high humidity) they prefer.
Combination Syndrome
Authors: Rajendran Sridharan , Baburajan FNU 
Published: July 2013

ABSTRACT
Combination syndrome (CS) is a dental condition that is commonly seen in patients with a completely edentulous maxilla and partially edentulous mandible with preserved anterior teeth. This syndrome consists of severe anterior maxillary resorption combined with hypertrophic and atrophic changes in different quadrants of maxilla and mandible. This makes it a challenging condition in dentistry that requires significant experience along with advanced restorative and surgical skills. The causes of maxillary bone resorption and ways to correct it are discussed in this article. Conventional treatment with full upper and partial lower dentures for the CS patients is not always adequate or satisfying for patients and it often requires multiple remakes due to continuing bone resorption. Dental implant rehabilitation challenges conventional treatment with bone-anchoring techniques to provide improved retention and stability for implant-retained and supported prostheses. This article presents a successful implant treatment of the partially edentulous maxilla in CS patient. The necessity of a multidisciplinary approach for early prevention and treatment of this complex condition is emphasized. This article illustrates a review of the changes and difficulties faced when treated with conventional approach which can be overcome with the aid of implant-supported prosthesis.

Potential Trade Distortion Effects of State Trading Enterprises under the Tariff-Rate Quota Scheme
Authors: Yoon Jung-Hyun , Lim Song Soo 
Published: July 2013

Abstract
The paper analyzes the potential trade distortion effects of state trading enterprises (STEs) on soybean imports to Korea. Traditionally, STEs have exercised exclusive rights to import the so-called strategic products, to ensure food security, domestic price stabilization, and import mark-ups. However, STE imports have been criticized on the grounds that industries using soybeans as a raw material are unable to obtain a diverse mix of quality material and cannot exercise the “right to choose” their own ingredients. Under a theoretical framework, a tariff equivalent of the STE is postulated to equate imports by private firms with imports by the STE. An empirical model is constructed and estimated using annual data spanning 1980–2009. The estimated results show that providing exclusive rights to imports has a negative effect on market access. When the STE pursues consumer welfare, the import-reducing effect turns out to be smaller than that in the producer welfare maximization case.
Cord Blood Transplantation for Cure of HIV Infections
Authors: Petz Lawrence 
Published: July 2013

Summary
HIV infection has not been cured by antiretroviral drugs or gene therapy, but it has been cured by a hematopoietic cell transplantation (HCT) that was performed for a patient with acute myeloid leukemia and HIV infection using peripheral blood stem cells from an adult donor homozygous for CCR5-Δ32 (CCR5-Δ32/Δ32). HIV has remained undetectable more than 6 years after discontinuation of antiretroviral therapy. However, this approach cannot be readily generalized because of the low prevalence of the CCR5-Δ32 allele and the need for a very close human leukocyte antigen (HLA) match between adult donors and recipients, as when bone marrow or peripheral blood stem cell transplants are performed. In contrast, cord blood (CB) transplants require less stringent HLA matching. CB units are being screened to develop an inventory of cryopreserved homozygous CCR5-Δ32 units available for HCT. One hundred eighty homozygous CCR5-Δ32 units have been identified, and 300 units are projected to provide for white pediatric patients a 73.6% probability of finding an adequately HLA-matched unit with a minimal cell dose of ≥2.5 × 107 total nucleated cells (TNC) per kilogram and for white adults a 27.9% probability. With a minimal cell dose requirement of ≥1 × 107 TNC per kilogram, the corresponding projected probabilities are 85.6% and 82.1%. CB transplantation does not require as stringent an HLA match between donor and recipient as bone marrow or peripheral blood HCTs, and HCT using cord bloods from donors homozygous for CCR5-Δ32 is, at the present time, the only feasible means of treatment of reasonable numbers of patients who are infected with HIV.

ObjectivesTo evaluate changes in the common duct diameter on sonography over time in patients with and without cholecystectomy.MethodsWe retrospectively evaluated the common duct diameter, central biliary dilatation, and interval change in 1079 patients who underwent sonography at least 2 years apart over a 6‐year period. A board‐certified radiologist, blinded to clinical and laboratory data, measured the duct diameter. A total of 893 patients (568 female and 325 male) were divided into 3 groups: group 1, remote cholecystectomy before sonography (mean, 9.7 years before sonography; n = 117); group 2, interval cholecystectomy between the first and second sonographic examinations (n = 56); and group 3, no cholecystectomy (n = 720). All groups were stratified by age, and group 3 was also stratified by the absence (n = 528) or presence (n=192) of gallstones.ResultsDuct diameters at baseline and follow‐up averaged 4.5 and 5.2, 3.6 and 4.9, and 3.5 and 3.9 mm in groups 1, 2, and 3, respectively. Group 1 ducts were larger at baseline than in the other groups (P < .001). At follow‐up, group 2 ducts showed a greater interval diameter increase than the other groups (P < .001). In a subanalysis of each group based on age, there was a mild increase in duct size with increasing age, although not clinically significant and within normal limits. In group 3 patients who never had gallstones, there was a significant small increase in duct size over decades (P < .001). The baseline duct sizes for patients with gallstones were not significantly different from those who never had gallstones (P = .15).ConclusionsPatients with remote cholecystectomy have larger common duct diameters than those with no or interval cholecystectomy. Most asymptomatic patients with or without cholecystectomy have a normal common duct diameter.

ObjectivesThe purpose of this study was to report our initial experience with transabdominal high‐intensity focused ultrasound (HIFU) therapy of the canine prostate and to determine the protective effect of rectal cooling during HIFU therapy.MethodsFifteen male dogs underwent transabdominal HIFU therapy of the prostate. Transabdominal HIFU was performed on 9 dogs without using a rectal cooling device, and the remaining 6 dogs underwent transabdominal HIFU with introduction of the rectal cooling device. Magnetic resonance imaging (MRI) was performed before, immediately after, and 1 week after the HIFU procedure. Rectal changes on MRI were classified into 4 grades (grades 0–3), and a comparison of the rectal change grades on MRI between the two groups was performed with the Mann‐Whitney U test.ResultsThe procedure failed for the first dog because of inadequate skin preparation. Of the remaining 14 dogs (8 without rectal cooling and 6 with rectal cooling), 4 showed focal signal changes in the prostate. The average rectal change grades on immediate postprocedural MRI were 2.63 for the non–rectal cooling group and 1.17 for the rectal cooling group (P = .0216). On 1‐week follow‐up MRI, the average grades were 1.20 for the non–rectal cooling group and 0.33 for the rectal cooling group (P = .1956).ConclusionsTransabdominal HIFU of the canine prostate was technically feasible, but the effect was limited because of anatomic and physiologic factors of the canine prostate. The rectal cooling device seems to have a protective effect on the rectum during the transabdominal HIFU procedure.
Mechanical, Solvent Imbibing, and Dielectric Behavior of Short Nylon Fiber/Poly(ethylene‐co‐vinyl acetate) Composites

Published: July 2013

ABSTRACTShort nylon fiber reinforced poly(ethylene‐co‐vinyl acetate) composites were prepared at different fiber loading. The cure, mechanical, solvent‐transport, dielectric, and thermal behaviors of the composites were analyzed. Special emphasis was placed on evaluating the effects of loading, length, and orientation of fibers on these properties. The maximum torque increases and the optimum cure time decreases with fiber loading. The hardness and abrasion resistance of the composite show improvements with fiber loading, while fiber incorporation lowers the tensile strength of EVA. The dielectric constant of the composite increases with fiber loading. © 2013 Wiley Periodicals, Inc. Adv Polym Technol 2013, 32, 21374; View this article online at wileyonlinelibrary.com.

Role of interleukin‐13 in fibrosis, particularly systemic sclerosis
Authors: O'Reilly Steven 
Published: July 2013

AbstractChronic inflammation can lead to altered extracellular matrix deposition and ultimately fibrosis. Interleukin‐13 (IL‐13) is a cytokine that was found to promote IgE class switching and inhibit proinflammatory cytokines. However, it is now recognized as an important mediator in allergy and most importantly fibrosis. Indeed, animal studies with genetically deleted mice have demonstrated its critical role in fibrosis and although it shares over lapping functions with IL‐4 it is the dominant cytokine in fibrosis. Systemic sclerosis is an autoimmune disease in which there is chronic inflammation and fibrosis. The disease is associated with a Th2 polarization and IL‐13 levels are elevated both in the blood and in the skin of patients. This review will examine the role of IL‐13 in driving fibrosis with a particular emphasis on systemic sclerosis as a prototypical fibrotic disease. It will highlight recent research into the role of IL‐13 and how this cytokine may be targeted in systemic sclerosis. © 2013 BioFactors, 39(6):593–596, 2013
Preparation and characterization of a novel dual‐retention mechanism mixed‐mode stationary phase with PEG 400 and succinic anhydride as ligand for protein separation in WCX and HIC modes
Authors: Song Chao , Wang Jianshan , Zhao Kailou , Bai Quan 
Published: July 2013

ABSTRACTA novel dual‐retention mechanism mixed‐mode stationary phase based on silica gel functionalized with PEG 400 and succinic anhydride as the ligand was prepared and characterized by infrared spectra and elemental analysis. Because of the ligand containing PEG 400 and carboxyl function groups, it displayed hydrophobic interaction chromatography (HIC) characteristic in a high‐salt‐concentration mobile phase, and weak cation exchange chromatography (WCX) characteristic in a low‐salt‐concentration mobile phase. As a result, it can be employed to separate proteins with both WCX and HIC modes. The resolution and selectivity of the stationary phase was evaluated under both HIC and WCX modes with protein standards, and its performance was comparable to that of conventional ion‐exchange chromatography and HIC columns. The results indicated that the novel dual‐retention mechanism column, in many cases, could replace two individual WCX and HIC columns as a ‘2D column’. In addition, the mixed retention mechanism of proteins on this ‘2D column’ was investigated with stoichiometric displacement theory for retention of solute in liquid chromatography in detail in order to understand why the dual‐retention mechanism column has high resolution and selectivity for protein separation under WCX and HIC modes, respectively. Based on this ‘2D column’, a new 2DLC technology with a single column was developed. It is very important in proteome research and recombinant protein drug production to save column expense and simplify the processes in biotechnology. Copyright © 2013 John Wiley & Sons, Ltd.

Published: July 2013

ABSTRACTA new capillary electrophoresis (CE) method using carboxymethyl‐β‐cyclodextrin (CM‐β‐CD) as chiral selector has been developed for the enantiomeric separation of meptazinol and its three intermediate enantiomers (intermediates II–IV), and validated for the application of quantitative determination of meptazinol in tablets. The primary factors affecting the separation efficiency, which include the chiral selector and its concentration, the buffer pH and composition, the organic modifiers used, and the applied voltage, were optimized. Baseline and satisfactory separations were obtained for meptazinol and its three intermediate enantiomers. For quantitative analysis of meptazinol, the method was performed at the condition using 2.0 mmol/L CM‐β‐CD in 20 mmol/L H3PO4 buffer adjusted to a pH of 6.00 with an applied voltage of 15 kV and containing 5% acetonitrile. After validation of the method in terms of its linearity, limits of detection and quantitation, accuracy, precision and selectivity, the method was successfully applied to the quantitation of meptazinol in pharmaceutical formulations.

Development and validation of a highly sensitive LC‐MS/MS method for quantitation of bivalirudin in human plasma: application to a human pharmacokinetic study
Authors: Chai Dong , Wang Rui , Bai Nan , Cai Yun , Liang Beibei 
Published: July 2013

ABSTRACTA sensitive, specific and simple LC‐MS/MS method was developed for the identification and quantification of bivalirudin in human plasma using diazepam as an internal standard (IS). The API‐4000 LC‐MS/MS was operated under multiple‐reaction monitoring mode using electrospray ionization. The sample preparation consisted of an easy protein precipitation sample pretreatment with methanol. Chromatographic separation was achieved on a Zorbax Eclipse plus C18 100 × 2.1 mm column with a mobile phase of water–methanol–0.1% formic acid. The analytes were detected with a triple quadrupole Quantum Access with positive ionization. Ions monitored in the multiple‐reaction monitoring mode were m/z 1091 → 650 for bivalirudin (at 2.70 min) and m/z 285 → 193 for diazepam (at 3.85 min). The developed method was validated in human plasma with a lower limit of quantitation of 20 µg/L for bivalirudin. A linear response function was established for the range of concentrations 20–10,000 µg/L (r > 0.998) for bivalirudin. The intra‐ and inter‐day precision values for bivalirudin met the acceptance criteria as per US Food and Drug Administration guidelines. Bivalirudin was stable in the battery of stability studies, viz. bench‐top, freeze–thaw cycles and long‐term stability. The developed assay method was applied to an intravenous administration study in humans. Copyright © 2013 John Wiley & Sons, Ltd.
