Le don, entre toute-puissance et pathologie
Authors: Reffait Christophe 
Published: December 2016

Consacré à l’étude comparative d’ Eugénie Grandet et de La Joie de vivre , cet article commence par rappeler en quoi ces deux romans présentent des exemples évidents de pathologie de l’intérêt, en particulier à travers les personnages du père Grandet et de Mme Chanteau : le premier prend place dans la galerie balzacienne des monomanes de l’or, la seconde est le sujet d’une véritable psychosomatique de l’intérêt déréglé. L’étude revient ensuite sur la macrostructure de ces romans : nous pouvons lire dans Eugénie Grandet le processus de vexation des sentiments par les intérêts passionnés qui se trouve décrit dans certains textes préfaciers balzaciens ; nous voyons se dessiner dans La Joie de vivre le phénomène de retournement du don sacrificiel en toute puissance qu’ont bien analysé Jean Borie et Jean-Louis Cabanès. Mais le présent article finit surtout par interroger la surestimation paradoxale de l’argent qui caractérise les dons faits par les protagonistes féminines Eugénie et Pauline à leurs amants : on reconnaît la classique métaphorisation du pucelage en trésor ; on constate que l’amour est informé par le langage de l’argent ; on se demande enfin si la pathologie de ces héroïnes ne consiste pas à surestimer les pouvoirs de leur don, cette relation pathologique constituant l’envers de la relation de crédit.
Du bébé entre ethnologie et psychanalyse : un « passionnant » objet anthropologique
Authors: Quirot Benoît 
Published: December 2016

Après un retour aux sources du concept d’« efficacité symbolique », le présent article décline les raisons principales faisant du nouveau-né humain – des théories entourant sa conception aux émotions, représentations et pratiques l’accueillant lors de sa venue au monde – un passionnant objet anthropologique. De l’ethnologie à la psychanalyse en passant par la psychologie interculturelle, il retrace le dialogue et parfois les points aveugles de ces disciplines dans l’approche du bébé et de sa rencontre avec ceux qui l’entourent : esquissant en quoi, à la lumière de travaux cliniques plus récents mais à la condition d’une réelle pluridisciplinarité, cette « situation anthropologique fondamentale » entourant les premiers liens ne devrait plus, désormais, être considérée comme un « petit sujet » pour la recherche anthropologique.
Conceptualisation de la psychothérapie d’enfants à la lumière des défis rencontrés en pédopsychiatrie et en protection de la jeunesse
Authors: Terradas Miguel M. , Domon-Archambault Vincent 
Published: December 2016

Les enfants consultant en pédopsychiatrie ou qui sont sous la responsabilité des autorités garantes de la protection de la jeunesse pré­sentent souvent un fonctionnement psychique axé sur l’agir au détriment de la pensée, de la parole et de la symbolisation. Il est donc nécessaire pour le clinicien de faire des adaptations des techniques d’intervention associées à la psychothérapie d’enfants d’approche psychanalytique dite classique pour être en mesure de les aider à développer ces processus psychiques, préalables à l’entreprise de ce type de psycho-thérapie. Les auteurs proposent une reconceptualisation de la psychothérapie d’enfants selon trois modalités d’intervention, soit le travail thérapeutique des conflits intrapsychiques et relationnels du jeune, la psychothérapie visant à rétablir la capacité à jouer et à faire semblant de l’enfant, et l’intervention centrée sur le développement des processus et fonctions psychiques nécessaires au travail thérapeutique du jeu traumatique chez le jeune. Ces trois modalités d’intervention sont illustrées à l’aide de cas cliniques.

Published: December 2016

Background: KwaZulu-Natal Sandstone Sourveld (KZNSS) is an endangered subtropical grassland type, of which a large proportion occurs within the eThekwini Municipal Area (EMA).Objectives: Examining the flora of KZNSS will allow a more fundamental understanding of the potential variability across remnant patches of this vegetation type, increasing the ability to accurately delimit KZNSS from adjacent similar vegetation types.Method: Floristic data were collected using quadrats and transects for three recognised KZNSS sites (Giba Gorge Environmental Precinct (GGEP), Inanda Mountain (IM) and Springside Nature Reserve (SSNR)), all within the EMA. Alpha diversity (Shannon’s exponential and Simpson’s inverse indices) and beta diversity measures were calculated and compared across all sites. An unweighted pair group method with arithmetic mean (UPGMA) analysis using the Jaccard index and a non-parametric multidimensional scaling (NMDS) ordination were used to assess similarity amongst quadrats across the three sites.Results: One hundred and thirty-one plant species were found to occur in GGEP, 95 in IM and 121 in SSNR. However, of the total 193 species found to occur collectively (i.e. quadrat and transect data combined) across the three sites, only 50 species were common to all these sites. The results of the alpha and beta diversity analyses revealed significant floristic variability both within and across the KZNSS sites sampled, with Shannon’s exponential index being highest in SSNR, followed by GGEP and lowest in IM. The lack of controlled access and unregulated burning regimes appear to have clearly affected the flora at the IM site in terms of species richness and increased evenness, as well as the relatively greater presence of introduced alien species and lower abundances of taxa of conservation concern. The pristine GGEP site had the highest number of species in total, with species being less evenly spread across the site, as well as the highest number of taxa conservation and low abundances of alien species. The main separations in the ordination results can be attributed to quadrat sampling performed pre- and post-burn.Conclusion: The floristic distinction of IM from GGEP and SSNR is attributed here to the intermediate disturbance effect of fire in grasslands which can lead to species loss if burning is too frequent. The implications of these findings are discussed in the context of the delimitation, classification and management of KZNSS

ABSTRACT
Objective: The objective of the study was to evaluate clinically and radiographically the efficacy of platelet-rich fibrin (PRF) versus β-tri-calcium phosphate (β-TCP) in the treatment of Grade II mandibular furcation defects. Materials and Methods: Forty-five Grade II furcation defect in mandibular molars which were assigned to open flap debridement (OFD) with PRF Group I (n = 15), to OFD with β-TCP Group II (n = 15), and to OFD alone Group III (n = 15) were analyzed for clinical parameters (probing pocket depth [PPD], vertical clinical attachment level [VCAL], horizontal clinical attachment level [HCAL], gingival recession, relative vertical height of furcation [r-VHF], and relative horizontal depth of furcation [r-HDF]) and radiographical parameters (horizontal depth of furcation [H-DOF], vertical height of furcation [V-HOF]) using cone-beam computed tomography (CBCT) at 6 months interval. Results: For clinical parameters, reduction in PPD and gain in VCAL and HCAL were higher in Group II as compared to Group I. Change in r-VHF and r-HDF was greater in Group II as compared to Group I. Mean percentage clinical vertical defect fill was higher in Group II as compared to Group I (58.52% ± 11.68% vs. 53.24% ± 13.22%, respectively). On CBCT, mean change at 6 months for all parameters showed nonsignificant difference between the two experimental groups. Mean change in V-HOF was higher in Group I as compared to Group II, but mean change in H-DOF and furcation width was more in Group II as compared to Group I. Conclusion: For both experimental and control groups, there was statistically significant improvement at 6 months follow-up from baseline values.

Authors: Tavassoli-Hojjati Sara , Sattari Mandana , Ghasemi Tayebeh , Ahmadi Rahil , Mashayekhi Abbas 
Published: December 2016

ABSTRACT
Objective: The purpose of this study was to evaluate the effect of different concentrations of platelet-rich plasma (PRP) on the proliferation of undifferentiated periodontal ligament (PDL) fibroblasts. Materials and Methods: The undifferentiated PDL fibroblasts were obtained from two healthy human premolar teeth and cultured in Dulbecco's modified Eagle's medium. Cell wells were divided into five groups. Experimental groups received 0.1%, 5%, or 50% PRP; the positive and negative control groups were cultured in fetal bovine serum (FBS) 12% and in a medium without FBS 12%, respectively. The plates were incubated at 37°C for 1, 2, 3, 4, and 7 days. PDL cell viability was assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide proliferation assay. Statistical analysis of the data was accomplished using repeated measure ANOVA and Tukey's test. P < 0.05 was considered statistically significant. Results: The 5% PRP had the greatest effect on undifferentiated fibroblast proliferation, which was significant on the 3rd day. There was no significant difference between 0.1% PRP and positive control during the first 3 days. The group with 50% PRP presented significantly lower proliferation, compared to other experimental and control groups. Conclusions: It may be concluded that the growth-stimulating effect of PRP is dose dependent with the best results in low concentrations.
Accuracy of cone-beam computed tomography in defining spatial relationships between third molar roots and inferior alveolar nerve
Authors: Pippi Roberto , Santoro Marcello , D'Ambrosio Ferdinando 
Published: December 2016

ABSTRACT
Objective: Cone-beam computed tomography (CBCT) has been proposed in surgical planning of lower third molar extraction. The aim of the present study was to assess the reliability of CBCT in defining third molar root morphology and its spatial relationships with the inferior alveolar nerve (IAN). Materials and Methods: Intraoperative and radiographic variables of 74 lower third molars were retrospectively analyzed. Intraoperative variables included IAN exposure, number of roots, root morphology of extracted third molars, and presence/absence of IAN impression on the root surface. Radiographic variables included presence/absence of the cortex separating IAN from the third molar roots on CBCT examination, number of roots and root morphology on both orthopantomography (OPG) and CBCT. The statistical association between variables was evaluated using the Fisher's exact test. Results: In all cases of intraoperative IAN exposure, the cortex appeared discontinuous on CBCT images. All cases, in which the cortical bone was continuous on CBCT images, showed no association with nerve exposure. In all cases in which nerve impression was identified on the root surface, the IAN cortex showed interruptions on CBCT images. No nerve impression was identified in any of the cases, in which the cortex appeared continuous on CBCT images. CBCT also highlighted accessory roots and apical anomalies/curvatures, not visible on the OPG. Conclusions: CBCT seems to provide reliable and accurate information about the third molar root morphology and its relationship with the IAN.
Are temporary anchorage devices truly effective in the treatment of skeletal open bites?
Authors: Turkkahraman Hakan , Sarioglu Mehmet 
Published: December 2016

ABSTRACT
Objective: The aims of this study were to evaluate the effects of temporary anchorage devices (TADs) in the treatment of skeletal open bites and to compare the results with untreated controls. Materials and Methods: A total of forty patients with skeletal anterior open bites were assigned to two groups of twenty each. The mean chronological age for the treatment group (14 female, 6 male) was 16.68 ± 2.80 years old, compared with 16.63 ± 2.83 years old for the control group (11 female, 9 male). Titanium miniplates fixed bilaterally to the infrazygomatic crest area were used as TADs and intrusive forces were applied to the posterior teeth with Ni-Ti coil springs. The treatment and normal growth changes were evaluated using 24 measurements (2 angular, 22 linear). Results: Statistically significant differences were found between the groups in Bx, By, Sn/GoGn, Ax-Bx, U6x, U6y, overjet, overbite, SN/OccP, N-Me, Ans-Me, S-Go/N-Me, interpremolar width, and intermolar width (P < 0.05). In the treatment group, statistically significant upper molar intrusion (mean ± standard deviation [SD], 3.59 ± 1.34; 95% confidence interval [CI], 2.96–4.22), posterior rotation of the occlusal plane (mean ± SD, 3.42 ± 2.17; 95% CI, 2.39–4.43), anterior rotation of the mandible (mean ± SD, 2.25 ± 1.91; 95% CI, 1.36–3.14), and resultant overbite improvement (mean ± SD, 4.82 ± 1.53; 95% CI, 4.10–5.53) were found (P < 0.05). Conclusions: Mild to moderate skeletal anterior open bites could easily be treated with TADs without orthognathic surgery. With the rigid anchorage of miniplates, true molar intrusion of up to 4 mm was achieved. With molar intrusion, anterior rotation of the mandible and a significant reduction in anterior face height were determined.

Published: December 2016

ABSTRACT
Objective: The purpose of this study was to assess the role of cross section on cyclic fatigue resistance of One Shape, Revo-S SU, and Mtwo rotary files in continuous rotation and reciprocating motion in dynamic testing model. Materials and Methods: A total of 90 new rotary One Shape, Revo-S SU, and Mtwo files (ISO size 25, taper 0.06, length 25 mm) were subjected to continuous rotation or reciprocating motion. A cyclic fatigue testing device was fabricated with 60° angle of curvature and 5 mm radius. The dynamic testing of these files was performed using an electric motor which permitted the reproduction of pecking motion. All instruments were rotated or reciprocated until fracture occurred. The time taken for each instrument to fracture was recorded. All the fractured files were analyzed under a scanning electron microscope (SEM) to detect the mode of fracture. Statistical analysis was performed using one-way ANOVA, followed by Tukey's honestly significant difference post hoc test. Results: The time taken for instruments in reciprocating motion to fail under cyclic loading was significantly longer when compared with groups in continuous rotary motion. There was a statistically significant difference between Mtwo rotary and the other two groups in both continuous and reciprocating motion. One Shape rotary files recorded significantly longer duration to fracture resistance when compared with Revo-S SU files in both continuous and reciprocating motion. SEM observations showed that the instruments of all groups had undergone a ductile mode of fracture. Conclusion: Reciprocating motion improved the cyclic fatigue resistance of all tested groups.

Published: December 2016

ABSTRACT
Objective: The objective of our study was to compare the fracture resistance and the mode of failure among three different post materials in primary anterior teeth. Materials and Methods: A total of sixty extracted primary anterior teeth were selected for the study. The samples were divided into three groups of twenty teeth each: Group I (Ribbond), Group II (Omega loop), and Group III (Glass fiber post). Pulp therapy was followed by intracanal post and crown buildup. The samples were mounted in self-cure acrylic and subjected to compressive strength test using universal testing machine (Instron). The maximum force at which the tooth fractured was recorded. Results: The values were subjected to one-way analysis of variance. The mean compressive strength values of Ribbond, omega loop, and glass fiber post were found to be 83.25 N, 61.60 N, and 75.55 N, respectively. The P value was found to be 0.220. Conclusion: Group I (Ribbond) showed the highest fracture resistance values followed by Group III (Glass fiber post) and Group II (Omega loop). Although there is difference in mean values, they were nonsignificant.

Optimal Superconvergence of Energy Conserving Local Discontinuous Galerkin Methods for Wave Equations
Authors: Cao Waixiang , Li Dongfang , Zhang Zhimin 
Published: December 2016

AbstractThis paper is concerned with numerical solutions of the LDG method for 1D wave equations. Superconvergence and energy conserving properties have been studied. We first study the superconvergence phenomenon for linear problems when alternating fluxes are used. We prove that, under some proper initial discretization, the numerical trace of the LDG approximation at nodes, as well as the cell average, converge with an order 2k+1. In addition, we establishk+2-th order andk+1-th order superconvergence rates for the function value error and the derivative error at Radau points, respectively. As a byproduct, we prove that the LDG solution is superconvergent with an orderk+2 towards the Radau projection of the exact solution. Numerical experiments demonstrate that in most cases, our error estimates are optimal, i.e., the error bounds are sharp. In the second part, we propose a fully discrete numerical scheme that conserves the discrete energy. Due to the energy conserving property, after long time integration, our method still stays accurate when applied to nonlinear Klein-Gordon and Sine-Gordon equations.
A Mathematical Analysis of Scale Similarity
Authors: Wang Z. J. , Li Yanan 
Published: December 2016

AbstractScale similarity is found in many natural phenomena in the universe, from fluid dynamics to astrophysics. In large eddy simulations of turbulent flows, some sub-grid scale (SGS) models are based on scale similarity. The earliest scale similarity SGS model was developed by Bardina et al., which produced SGS stresses with good correlation to the true stresses. In the present study, we perform a mathematical analysis of scale similarity. The analysis has revealed that the ratio of the resolved stress to the SGS stress isγ2, whereγis the ratio of the second filter width to the first filter width, under the assumption of small filter width. The implications of this analysis are discussed in the context of large eddy simulation.
High Order Accurate Direct Arbitrary-Lagrangian-Eulerian ADER-MOOD Finite Volume Schemes for Non-Conservative Hyperbolic Systems with Stiff Source Terms
Authors: Boscheri Walter , Loubère Raphaël 
Published: December 2016

AbstractIn this paper we present a 2D/3D high order accurate finite volume scheme in the context of direct Arbitrary-Lagrangian-Eulerian algorithms for general hyperbolic systems of partial differential equations with non-conservative products and stiff source terms. This scheme is constructed with a single stencil polynomial reconstruction operator, a one-step space-time ADER integration which is suitably designed for dealing even with stiff sources, a nodal solver with relaxation to determine the mesh motion, a path-conservative integration technique for the treatment of non-conservative products and ana posterioristabilization procedure derived from the so-called Multidimensional Optimal Order Detection (MOOD) paradigm. In this work we consider the seven equation Baer-Nunziato model of compressible multi-phase flows as a representative model involving non-conservative products as well as relaxation source terms which are allowed to become stiff. The new scheme is validated against a set of test cases on 2D/3D unstructured moving meshes on parallel machines and the high order of accuracy achieved by the method is demonstrated by performing a numerical convergence study. Classical Riemann problems and explosion problems with exact solutions are simulated in 2D and 3D. The overall numerical code is also profiled to provide an estimate of the computational cost required by each component of the whole algorithm.
