Investigation of joints between polypropylene and polybutylene terephthalate
Authors: Bekem Aylin , Unal Ahmet 
Published: April 2015

Abstract
An effective joining between polypropylene (PP) and polybutylene terephthalate (PBT) is closely related to bonding between PP and PBT. The objective of this study is to improve the bonding between PBT and PP with a compatibilizer application between joints as tie-layer at various concentrations. Flexural strength, lap-shear strength and interlaminar shear strength of joined parts were determined to determine the adhesive bonding performance. The fracture behavior of the bonds was also investigated. It was found that using compatibilizers in a PP/PBT joining system improved the mechanical characteristics. Improved results were obtained with increasing ratios of compatibilizers in tie-layer and maximum mechanical results were achieved for 100 % compatibilizer usage in PP-PBT system.

Authors: Krishnan Muthuraman Pandi , Sait Abdullah Naveen , Ravichandran Manickam 
Published: April 2015

Abstract
In the present study, seam welding process parameters were optimized for joining 306 stainless steel plates. Welding pressure, welding speed and welding temperature combinations were carefully selected with the objective of producing a weld joint with maximum impact strength and hardness. Taguchi technique was applied for optimizing the selected welding parameters. The factors used in this study consisted of pressure, welding speed and welding temperature, each of which had three levels in the study. L27 orthogonal array and corresponding levels were selected according to the aforementioned factors and experimental tests were performed. Signal-to-noise (S/N) ratio was used to evaluate the experimental results. The results indicate that the welding speed has the greatest influence on impact strength, followed by welding pressure and temperature. Experiments have also been conducted to validate the optimized parameters.

Authors: Danışman Murat , Kocabaş Mustafa , Cansever Nurhan 
Published: April 2015

Abstract
In order to investigate the different Cr-N formation characteristics of plasma nitrided hard Cr coatings, Cr was electrodeposited on AISI 1010 steel and plasma nitrided at 600, 700 and 800 °C for 3 h, 5 h and 7 h, respectively. Phase analyses of resulting Cr-N phases and grain size of Cr layer before and after nitriding process were calculated by X-ray diffraction analysis. Structure of nitride layer and its thickness were analyzed using scanning electron microscopy micrographs. The micrographs indicated that samples consisted of three distinctive layers. In order to distinguish these layers, scanning electron microscopy and energy dispersive spectroscopy (EDX) analysis were used as well as elemental distribution versus depth was plotted. The Cr-N diffusion was investigated by layer thickness measurements, and diffusion coefficient as well as activation energies were calculated.
Le rôle des acteurs dans la gestion d’un projet d’implantation d’un tableau de bord dans le secteur médico-social
Authors: Lemaire Célia , Nobre Thierry 
Published: April 2015

Cet article traite des rôles des acteurs organisationnels dans la conduite d’un projet : la mise en œuvre du tableau de bord partagé des établissements et services médico-sociaux. Ce projet implique de nombreux acteurs dans une configuration inter-organisationnelle : des établissements et services du secteur, et leurs représentants, des Agences Régionales de Santé, des Conseils Généraux, l’Agence Nationale d’Appui à la Performance (ANAP), la Direction Générale de la Cohésion Sociale et la Caisse Nationale de Solidarité et d’Autonomie. L’ANAP a défini des rôles pour chacun des types d’acteurs concernés par le projet, devenant alors un émetteur de rôles selon le modèle de séquence de rôles, proposé par Katz et Kahn (1966). L’analyse des rôles résulte d’une observation participante longitudinale, impliquant l’un des chercheurs dans le processus d’introduction de l’outil. Les résultats détaillent les rôles transmis par l’ANAP et établissent une comparaison avec les rôles effectivement joués par les différents acteurs. Le différentiel entre ces deux types de rôles est expliqué par trois facteurs principaux : l’avancée du projet, l’illusion perçue d’une transmission de rôles et un manque de concertation entre les différents acteurs. Nos contributions académiques sont l’introduction de la dimension dynamique au modèle de Katz et Kahn et la confirmation du rôle central du coordonnateur dans une configuration inter-organisationnelle. Notre contribution managériale réside dans la proposition de pistes d’amélioration du management des rôles dans la conduite d’un projet.
L’interdiction des retranscriptions pharmaceutiques : Adaptation du management aux conventions sociales
Authors: Orvain Jacques , Harmel Cyrille 
Published: April 2015

Objectif : La sécurisation des prescriptions pharmaceutiques est aujourd’hui considérée comme un enjeu important de la qualité des soins, mais qui se heurte à des conflits de rationalité. Méthode : Une étude de cas menée dans un hôpital français a permis d’analyser en profondeur les freins organisationnels qui sont à l’origine des difficultés rencontrées. L’étude a été menée en s’appuyant, d’une part sur la théorie des conventions, d’autre part sur les modalités de déploiement du management de la qualité. Résultats : Trois thématiques principales émergent de l’étude et peuvent être interprétées comme des conflits entre différents cadres conventionnels. Tout d’abord l’interdiction des retranscriptions des prescriptions médicales, en second lieu l’établissement de la pharmacie clinique comme une nouvelle fonction permettant la sécurisation des prescriptions, enfin l’informatisation des prescriptions comme espace de négociation. Discussion et conclusion : Pour organiser la médiation entre différentes conventions, le manager hospitalier pourra se référer à trois types de gestion qui ont été décrites pour manager la qualité. La gestion de type instrumental permet d’exclure les retranscriptions, la gestion de type organique permet d’accueillir la pharmacie clinique comme une nouvelle fonction, enfin la gestion de type culturel qui s’appuie sur la discussion et l’arbitrage des valeurs ouvre la voie à la négociation de l’informatisation du circuit du médicament.
Chapitre 2. L’information, droit fondamental du patient ?
Authors: Mémeteau Gérard 
Published: April 2015

Bien qu’exprimées avant l’affaire « Lambert », qui a conduit à penser les refus et assentiments sur la scène du droit interne, celle du droit conventionnel – et celle du lit du malade ! – ces remarques simples présentent le droit du malade à l’information médicale comme un droit dit fondamental. Mais, il ne se comprend qu’en vue d’un traitement ou autre acte médical ; à défaut, il n’a point lieu d’être, n’est qu’un exercice académique, du reste excitant, mais à lui seul peu curatif. Et, si l’on renversait les termes du problème : le droit du médecin à l’information ? (La belle thèse de Ph. Gaston, Paris 8, 2 décembre 2014)...
« Pratiquer ses rêves ». Rêves, divinités et pratiques sociales dans les Andes péruviennes
Authors: Cecconi Arianna 
Published: April 2015

Les croyances relatives à la dimension onirique ont une longue histoire dans le contexte péruvien. Dans cet article, nous étudierons la valeur des rêves et leur usage social au sein du milieu andin contemporain. La grande perméabilité des frontières entre « intériorité » et « extériorité », « âme » et « corps », « individuel » et « collectif », « humains » et « divinités » sera mise en évidence par l’analyse des rêves des villageois de deux communautés paysannes des Andes centrales du Pérou. Les descriptions de ces rêves ouvriront des perspectives sur plusieurs dimensions religieuses et rituelles, tandis qu’à travers l’étude de certaines « iconographies oniriques », nous pourrons observer la cohabitation entre divinités de provenances hétérogènes. Les liens intimes qui se tissent entre les croyances aux rêves et aux divinités, les expériences du corps et les pratiques sociales manifesteront finalement l’extrême fluidité des continuités qui s’instituent entre vie diurne et vie nocturne.
Travail du rêve, travail de la culture dans une thérapie mère-enfant (Congo)
Authors: Pierre Danièle 
Published: April 2015

Dans la rencontre avec les patients migrants, l’évocation des rêves est souvent précieuse. Elle permet notamment d’entrer en contact avec leurs conceptions culturelles des désordres. À partir de la théorie freudienne et à travers une histoire clinique, nous montrons comment le système de sens - la « vision du monde » - entre dans l’élaboration secondaire des rêves et contribue ainsi au travail de la cure.
« La Révélation... tout simplement »
Authors: Bacq Philippe 
Published: April 2015

En contrepoint de la lecture de Y. Labbé dans un numéro précédent ( NRT 126 [2004] 106-129), l’A. présente ici la démarche en sept chapitres de Ch. Theobald dans son livre La Révélation . Partant inductivement de l’expérience humaine d’un inouï de la vie (ch. 1) cristallisée dans des traditions religieuses diversifiées que le critère du respect permet d’apprécier (ch. 3), celui qui « lit les Écritures » (ch. 4) découvre dans la personne du Christ en relation aux autres d’abord, en relation au Père et à l’univers dans la résurrection ensuite, l’autorévélation de l’inouï de Dieu (Vatican II au ch. 2). L’accueil de cet excès d’humanité en Christ invite à adopter le point de vue de Dieu sur nos existences individuelles (ch. 5) et collectives (ch. 6) et fait monter à nos lèvres un chant de louange au Dieu qui se révèle comme agissant en ressuscité au cœur de la création (ch. 7).
A Inserção Social dos Programas Stricto Sensu em Administração das Universidades Públicas e a Coprodução do Bem Público
Authors: Salm José Francisco , Da Silva Maria Helena 
Published: April 2015

O artigo discute as ações de inserção social dos programas de pós-graduação stricto sensu em administração sob a supervisão da CAPES, a partir dos modelos de coprodução. Os dados utilizados ao longo do artigo são do aplicativo Coleta da CAPES, no período de 2007, 2008 e 2009. As ações de inserção social identificam-se como coprodução funcional (eficiência e eficácia formal) e coprodução simbólica (presença formal do poder público) e raras ações de coprodução representativa com sustentabilidade (integração sustentável com a sociedade). Evidencia, também, que essas ações de inserção social são realizadas mediante a solicitação de serviços aos programas, assistência à sociedade sob diversas formas e por meio de ajuste mútuo entre os programas e a sociedade. Os dados contidos no aplicativo Coleta não comprovam que esses programas diretamente promovem a transformação social (ausência de acompanhamento de egressos). Também demonstram que muitos programas não têm uma compreensão precisa sobre o que é inserção social e como ela deve ser realizada para os efeitos de avaliação da CAPES.
Charles Henri Ford'sBlues:
Authors: Howard Alexander 
Published: April 2015

ABSTRACTThis article focuses on the early editorial and literary career of Charles Henri Ford (1908–2002). Spanning much of the twentieth century, Ford's multiform aesthetic sensibility incorporated poetry, visual art, filmmaking, photography, and magazine editing. Despite the breath and depth of his interests and achievements, little critical attention has been paid to Ford. My article addresses this imbalance. It recovers an unfairly marginalized poet and editor whose little magazine sought to renovate modernism along decidedly queer lines. The first section contextualizes Ford and his second-generation modernist little magazine. The subsequent sections chart the magazine's trajectory.

Kennis en waar de nieuwe beleidsideeën vandaan komen
Om iets met de uitdagingen van morgen aan te kunnen, zullen onze overheden radicaal nieuwe beleidsvormen moeten ontwikkelen. Hiertoe zullen ze bewust op zoek moeten naar nieuwe ontwerpen en nieuwe combinaties van beleid. Er is een veelheid aan ontwerppraktijken waaruit ze kunnen putten. Maar dan zullen ze eerst wel moeten erkennen dat beleid maken een creatief proces is en het ook als zodanig vormgeven.
Application of Methyl Silane Coated Iron Oxide Magnetic Nanoparticles for Solid-Phase Extraction and Determination of Fat-Soluble Vitamins by High Performance Liquid Chromatography
Authors: Momenbeik Fariborz , Yazdani Elham 
Published: April 2015

Abstract
Methyl silane coated Fe3O4 magnetic nanoparticles were used for simultaneous extraction of the fat-soluble vitamins (FSVs). The amounts of extracted vitamins were determined by HPLC. The synthesized Fe3O4 nanoparticles were coated with silica and then modified withtrimethoxymethylsilane (TMMS). The prepared particles were characterized by different methods. The best amounts of silica and TMMS in sorbent synthesis were1.2 and 0.5 mL, respectively. The optimum pH values for the sample solution and washing buffer were 5 and 3, respectively. Application of 100 mg sorbent, 700 μL tetrahydrofuran, 5-fold dilution of the sample solution, and 1 min for sorption and desorption times were among the best conditions. At the optimum conditions, the calibration plots for each vitamin were obtained with good linearity (R2 &gt;0.9992) and suitable linear ranges. This method has a low LOD (&lt;76.1 μg/mL), acceptable repeatability (RSD &lt;5.63%) and reproducibility (RSD&lt;4.71%), and good accuracy (recovery &gt;90.3%). Preconcentration of low concentrations of vitamin D3 was performed, and results showed 3.7 times greater sensitivity after preconcentration. Finally, the amounts of the FSVs in pharmaceutical formulations were determined using the proposed method, and results showed good agreement with those reportedby manufacturers.
Quantitative Analysis of Paraquat in Vegetation by Stable Isotope Dilution and Liquid Chromatography/Electrospray Ionization-Mass Spectrometry
Authors: Schaner Angela , Hickes Heidi 
Published: April 2015

Abstract
The method presented is a suitable approach for routine testing of paraquat in difficult sample types, such as winter wheat and alfalfa plant tissue, typically found with accidental spray drift. Hydrophilic interaction chromatography and ultra-performance LC is utilized with tandem quadrupole MS in the positive electrospray ionization mode. Three precursor-product ion transitions are measured in the multiple reaction monitoring mode, and paraquat d8 is added as an internal standard at the beginning of the extraction procedure to correct for losses in recovery and/or matrix effects in instrument response. A 5 g portion is digested with 6 M HCl in a 100°C water bath for 1 h. An aliquot is removed and adjusted to pH 7–8 prior to loading on a mixed mode weak cation-exchange SPE cartridge, and paraquat is eluted with formic acid–acetonitrile (10 + 90, v/v). Average recoveries of paraquat fortified at 0.020–0.080 ppm in winter wheat and alfalfa ranged from 80 to 114% (RSD 12–30%). Result data from naturally incurred paraquat (0.027–0.51 ppm) in composite garden plants, potato leaves, tree leaves, and alfalfa are presented. The LOQ is 0.020 ppm.
Simultaneous Determination of 24 Polycyclic Aromatic Hydrocarbons in Edible Oil by Tandem Solid-Phase Extraction and Gas Chromatography Coupled/Tandem Mass Spectrometry
Authors: Xu Ting , Tang Hua , Chen Dazhou , Dong Haifeng , Li Lei 
Published: April 2015

Abstract
An efficient and fast tandem SPE method followed by GC/MS/MS has been developed for the determination and the quantification of 24 polycyclic aromatic hydrocarbons (PAHs) in edible oil. This method includes the monitoring of 15 + 1 PAHs designated as a priority by the European Union in their 2005/108/EC recommendation and 16 PAHs listed by the U. S. Environmental Protection Agency. The sample preparation procedures were based on SPE in which PAH-dedicated cartridges with molecularly imprinted polymers and graphitized carbon black were used in series. The novel tandem SPE combination of selective extraction and purification of light and heavy PAHs provided highly purified analytes. Identification and quantification of 24 target PAHs were performed using GC/MS/MS with the isotope dilution approaches using D-labeled and 13C-labeled PAHs. The advantages of GC/MS/MS as compared to other detection methods include high sensitivity, selectivity, and interpretation ability. The method showed satisfactory linearity (R2 &gt; 0.998) over the range assayed (0.5–200 μg/kg); the LODs ranged from 0.03 to 0.6 μg/kg, and LOQs from 0.1 to 2.0 μg/kg. The recoveries using this method at three spiked concentration levels (2, 10, and 50 μg/kg) ranged from 56.8 to 117.7%. The RSD was lower than 12.7% in all cases. The proposed analytical method has been successfully applied for the analysis of the 24 PAHs in edible oil.

Authors: Mostafa Nadia M , Abdel-Fattah Laila , Weshahy Soheir A , Hassan Nagiba Y , Boltia Shereen A 
Published: April 2015

Abstract
A stability-indicating spectrofluorometric method was investigated for the determination of three cephalosporin drugs, namely, cefpodoxime proxetil (CPD), cefixime trihydrate (CFX), and cefepime hydrochloride (CPM), via their acid and alkali degradation products. The three drugs were determined via their acid degradation at 432, 422, and 435 nm using an excitation wavelength of 310, 330, and 307 nm for CPD, CFX, and CPM determination, respectively, and via their alkali degradation at 407, 411, and 405 nm using an excitation wavelength of 310, 305, and 297 nm for CPD, CFX, and CPM determination, respectively. Linearity was achieved in the ranges of 0.35–3.50,0.4–4.0, and 0.3–3.0 μg/mL for the acid degradation products of CPD, CFX, and CPM, respectively, and in ranges of 0.05–0.5, 0.1–1.0, and 0.08–0.80 μg/mL for the alkali degradation products of CPD, CFX, and CPM, respectively. The method was validated for various parameters according to International Conference on Harmonization guidelines. The method was successfullyapplied for the determination of these cephalosporindrugs in pharmaceutical dosage forms with good accuracy and precision. The results obtained by the proposed spectrofluorometric method were compared with good agreement to the official HPLC method.
Development and Validation of a Simple and Robust Method for Arsenic Speciation in Human Urine Using HPLC/ICP-MS

Published: April 2015

Abstract
In order to better distinguish the different toxic inorganic and organic forms of arsenic (As) exposure in individuals, we have developed and validated a simple and robust analytical method for determining the following six As species in human urine: arsenous (III) acid (As-III), As (V) acid, monomethylarsonic acid, dimethylarsinic acid, arsenobetaine (AsB), and arsenocholine. In this method, human urine is diluted using a pH 5.8 buffer, separation is performed using an anion exchange column with isocratic HPLC, and detection is achieved using inductively coupled plasma-MS. The method uses a single mobile phase consisting of low concentrations of both phosphate buffer (5 mM) and ammonium nitrate salt (5 mM) at pH 9.0; this minimizes the column equilibration time and overcomes challenges with separation between AsB and As-III. In addition, As-III oxidation is prevented by degassing the sample preparation buffer at pH 5.8, degassing the mobile phase online at pH 9.0, and by the use of low temperature (–70 °C) and flip-cap airtight tubes for long term storage of samples. The method was validated using externally provided reference samples. Results were in agreement with target values at varying concentrations and successfully passed external performance test criteria. Internal QC samples were prepared and repeatedly analyzed to assess the method's long-term precision, and further analyses were completed on anonymous donor urine to assess the quality of the method's baseline separation. Results from analyses of external reference samples agreed with target values at varying concentrations, and results from precision studies yielded absolute CV values of 3–14% and recovery from 82 to 115% for the six As species. Analysis of anonymous donor urine confirmed the well-resolved baseline separation capabilities of the method for real participant samples.

Published: April 2015

Abstract
A novel isocratic RP–HPLC method with UV photodiode array detection for the determination of seven organic acids in vinegar samples was developed and optimized. Samples were analyzed on a C18 (150 × 4.6 mm id, 5 μm) analytical column. Methanol–0.010 M sodium dihydrogen phosphate buffer adjusted with H3PO4 to pH 2.80 (2 + 98, v/v), was used as the mobile phase. The column oven temperature was optimized at 23.0°C, the flow rate was 0.80 mL/min, and the detection wavelength was 210 nm. Matrix-matched calibration curves were prepared for all analytes, and the correlation coefficients were greater than 0.99. LOD and LOQ ranged from 0.10 to 10.0 and 0.30 to 30.0 μg/mL, respectively. The results for interday and intraday precision and accuracy fell within the ranges specified. Vinegar samples were quantified by the standard addition method. The main advantages of this method are its selectivity, which is one of themain weaknesses of most methods when determining organic acids in complex matrixes, and its simplicity since little sample preparation is needed. Moreover,it is safe and inexpensive with low organic solvent usage.
Du castor cosmique au castor travailleur : histoire d’un transfert culturel
Authors: Delâge Denys 
Published: April 2015

Nous partons des travaux de François-Marc Gagnon sur les images des castors canadiens aux XVIIe et XVIIIe siècles, pour élaborer sur l’éthologie du castor et sa place dans l’univers symbolique autochtone. Nous traitons ensuite du castor dans la traite des pelleteries, puis de la perception coloniale du castor. Nous y analysons les mécanismes de transfert culturel d’un mythe autochtone du castor acteur primordial de la genèse, à celui, profane, d’un ordre social hiérarchique ou républicain fondé sur l’éthique du travail à la manière des castors. S’y greffe, la conviction de l’existence d’une société des castors analogue à celle des « Sauvages », toutes deux condamnées à disparaître devant l’avance du progrès et de la civilisation.
