Valeur(s), exploitation et économie des conventions
Authors: Favereau Olivier
Published: January 2019

Le programme conventionnaliste entend déplacer les conventions du langage théorique en économie vers une réimbrication des dimensions « coordination » et « reproduction », tout en autorisant une interpénétration des deux autres dimensions « valeurs » et « rationalité ». Cela a conduit Boltanski et Chiapello (1999) à considérer l’exploitation et la justification comme l’inverse l’une de l’autre. Un lien direct avec Marx devient possible. Marx fait toutefois apparaître l’exploitation non dans l’espace des prix mais dans un espace des valeurs, objectivement mesurables (en heures de travail abstrait), alors que l’économie des conventions opère avec un espace des valeurs, au sens commun, normatif, du terme, mobilisant des entités intersubjectives (telle la justice). Le grand projet marxien d’intelligibilité du capitalisme à partir de la mise à nu de l’injustice capital/travail n’est pas prisonnier de la théorie de la valeur-travail. La distinction conventionnaliste de l’entreprise et de la société, dissimulée dans le « Régime d’Intersubjectivité et de Normativité » néolibéral, permet de faire apparaître dans le nouvel espace des valeurs, un usage indu du droit de propriété par les actionnaires de la société, qui s’approprient, au-delà des revenus de facteurs, le revenu proprement collectif de l’organisation qu’est l’entreprise. Cette forme d’exploitation, objectivement mesurable, entrevue par Proudhon dès 1840, ne peut être remise en cause sans la généralisation de la codétermination, dans le gouvernement des entreprises.

Du corps virtuel au réel du corps en gériatrie
Authors: Talpin Jean-Marc
Published: January 2019

Le vieillissement dépendant met en avant la question du corps dans plusieurs dimensions qui seront développées dans une perspective à la fois clinique, psychanalytique et politique : corps des âgés et leurs atteintes motrices, sensorielles ou cognitives ; corps de professionnels entre fatigue et usure. Ces corps, entre épaisseur biologique et investissements pulsionnels et les défenses afférentes, seront mis en tension et en perspective avec l’irruption des technologies hypermodernes qui seront comprises comme témoignant du déni du réel du corps vieux, abîmé, et d’une nouvelle version du fantasme d’immortalité. La dimension de la sécurité et/ou de l’emprise sur les corps fera l’objet d’une attention particulière.
Ensauvagement des corps, sujets en errance et brutalité du monde
Authors: Bruyère Thierry , Gaillard Georges
Published: January 2019

La dialogique inclusion/exclusion est l’une des dynamiques-clefs qui « travaille » nos sociétés hypermodernes. Les « exclus » sont les témoins vivants de l’insupportable de la déstructuration de la Polis (du « vivre ensemble » dans la cité). Ces sujets sont renvoyés sur les marges du monde, là où ce n’est plus la souffrance qui signifie la difficulté du sujet à advenir, mais la douleur du corps, ou plutôt l’impossibilité pour le sujet de symboliser sa douleur. Les corps abandonnés, sans soin ni attention, se font les stigmates d’un état de déshérence. Non réductibles au seul mortifère à l’œuvre au sein d’histoires individuelles, ces corps exhibés témoignent paradoxalement de stratégies de survie, dans un rapport meurtri au corps social. Cet « ensauvagement » du corporel scénarise dès lors, en négatif, la brutalité de nos sociétés, dans le mouvement même où il permet à ces sujets de s’y soustraire. Dans cet article, nous tenterons de comprendre en quoi le corps de ces sujets se fait le signe de la dynamique sociale de l’exclusion ; ceci du fait que la dimension corporelle participe fondamentalement aux relations sociales plus larges et à leur pérennisation. Une situation clinique d’accompagnement au long cours permettra de mettre à jour les processus de la douleur et de la survie, de ces sujets désignés parfois comme de « grands exclus ».
La camisole ne va pas de soi ! Note sur l’actualité de la contention et de l’isolement en psychiatrie
Authors: Bittolo Christophe
Published: January 2019

Cet article témoigne de l’évolution et de la dégradation préoccupante des conditions institutionnelles dans lesquelles les patients sont hospitalisés en psychiatrie adulte. Les pratiques de « contention mécanique » et le recours à la « chambre d’isolement », en augmentation et récemment réglementés, témoignent selon nous du manque autant de moyens humains pour contenir les troubles et la souffrance que d’espaces de travail collectif en équipe dans lesquels la vie psychique des patients et des soignants peut être prise en compte. À défaut, les impératifs disciplinaires d’adaptation corporelle et comportementale prennent le devant et montrent les difficultés à rester en contact avec les souffrances psychotiques.
La clinique psychopathologique au regard de l’œuvre de W.R. Bion
Authors: Korff-Sausse Simone
Published: January 2019

Résumé L’auteur se propose de montrer l’apport spécifique de la pensée de Bion à la psychopathologie psychanalytique. Le modèle du fonctionnement psychique de Bion permet d’éclairer et de traiter les situations cliniques extrêmes qui sont peu abordées par la psychanalyse classique. Les thèmes abordés sont la structure, les parties psychotiques et non psychotiques, le non-verbal, le contre-transfert, l’intersubjectivité. En précisant ces concepts kleiniens, postkleiniens, bioniens, post-bioniens, on pourra ouvrir le débat avec d’autres courants de la psychanalyse.
L’usure et la nouveauté
Authors: Chabert Catherine
Published: January 2019

Résumé L’auteur propose d’abord une discussion critique du texte de Winnicott à propos du contre-transfert et de ses catégorisations selon les modalités de fonctionnement psychique du patient. Puis est développée une étude clinique de cure où sont mises en évidence les caractéristiques fondamentales du contre-transfert et de ses effets, du fait de son essence sexuelle inconsciente.
Régression, fusion, traumatisme
Authors: Marinov Vladimir
Published: January 2019

Résumé À travers deux vignettes cliniques, ce texte veut démontrer comment l’analyse des moments régressifs peut être féconde dans le travail avec des patients à la limite de la psychose, et instaurer, comme le suggère Winnicott à juste titre, une « relation directe de nature primitive qui va jusqu’à la fusion ». Derrière cette fusion, qui peut prendre un aspect délirant, il s’agit d’analyser les traumas infantiles réactivés dans l’après-coup de la relation transférentielle.
Contribution à une métapsychologie de la présence
Authors: Cornalba Vincent
Published: January 2019

Résumé Le mouvement particulier de l’article de Winnicott, entre rigueur orthodoxe et ouverture à une autre appréhension du contre-transfert, illustre l’ajustement nécessaire du thérapeute confronté à une impasse dans le travail de symbolisation chez l’analysant. Loin de représenter un frein à la dynamique de la cure, comme il est habituel de l’envisager dans la névrose, le contre-transfert accède alors au statut d’outil indispensable pour réinscrire un matériau psychique dans l’œuvre de symbolisation. La qualité de présence de l’analyste est déterminante en tant qu’elle prend en compte les conditions qui ont présidé au processus de symbolisation dans la rencontre avec l’objet, autre-sujet.
Prise en charge des adolescents incarcérés
Authors: Arotcharen Julien , Aboudou Badria
Published: January 2019

L’intervention d’un clinicien en prison est souvent associée aux représentations et appréhensions de ce qu’est un détenu. Un effet « miroir brisé  1 » que l’on retrouve auprès des adolescents incarcérés, de leur famille et du clinicien qui les accompagne. Néanmoins, il est indispensable de se préoccuper du vécu psychique de ces adolescents et jeunes adultes pouvant pour certains, bénéficier d’une prise en charge dans un service médico-psychologique, au même titre que n’importe quel patient. Une préoccupation qui est au cœur du dispositif de soin des patients incarcérés.
Consultation Extra-Carcérale (CEC)
Authors: Canetti Cyrille
Published: January 2019

Le projet de la consultation extra-carcérale (CEC) du centre hospitalier Sainte-Anne (CHSA) de Paris flotte dans les esprits de l’équipe du SMPR depuis des années mais elle n’a réellement ouvert ses portes qu’en 2014, au moment où la maison d’arrêt de Paris-la Santé fermait les siennes pour rénovation. Sa mission principale : proposer la continuité des soins aux personnes sortant de prison, sans pour autant créer une filière ségrégative ni devenir un auxiliaire de justice. En quatre ans, elle a montré son utilité et permet à de nombreux patients d’être accompagnés dans le moment souvent difficile de la sortie de prison et d’être, le cas échéant orientés vers les structures de soins de droit commun.
La danse de la thérapie ; quelques figures qui portent
Authors: Gennart Michèle
Published: January 2019

La psychothérapie est une pratique de soins dont les conditions de possibilité et d’action reposent de part en part sur l’intersubjectivité. Comment tenter de décrire, dès lors, non les techniques que les thérapeutes utilisent, mais les processus intersubjectifs mêmes qui s’avèrent soignants ? La réponse à une telle question implique bien sûr les « soignés » eux-mêmes, dont l’expérience et le savoir qui en est issu sont incontournables. En dialogue avec deux patientes ayant un parcours de soins consistant, l’auteur décrit cinq dimensions ou figures de la « danse thérapeutique ».
Intervention systémique brève intégrative (ISBI) pour couples parents : dialogue entre recherche et clinique
Authors: de Roten Yves , Carneiro Claudio , Imesch Camille , Vaudan Christel , Eira Nunes Cindy , Favez Nicolas , Darwiche Joëlle
Published: January 2019

La littérature clinique systémique a beaucoup thématisé l’impact du conflit conjugal sur la coparentalité et sur les problèmes de l’enfant, mais peu l’effet de la coparentalité sur les deux autres sous-systèmes. Cet article présente un modèle d’intervention clinique pour les couples parents développé à Lausanne depuis quelques années, l’intervention systémique brève intégrative (ISBI), issu d’un projet de recherche construit autour de l’intégration des perspectives conjugales et coparentales dans la prise en charge thérapeutique de couples parents. Des exemples de données de recherche permettent d’illustrer l’intérêt d’intégrer ces perspectives dans la pratique clinique avec des couples parents.

Self-Directed Learning Among Nurse Learners in Sri Lanka
Authors: Samarasooriya Ranjanie C. , Park Jiyoung , Yoon Sook Hee , Oh Jina , Baek Suyon
Published: January 2019

Background:

Although self-directed learning (SDL) has become an essential instrument for educating nursing professionals, little is known about SDL among nurses in a developing country.

Method:

Data were collected using a structured self-reporting survey, which included Fisher's Self-Directed Learning Readiness (SDLR) scale, and a multiple linear regression analysis was conducted.

Results:

The mean score per item on the SDLR was 4.31 of 5. The learning-related factors that influenced SDLR were motivation for learning and self-efficacy in English proficiency, and the working-related factor was job satisfaction. These variables accounted for 17.6% of the variance in SDLR scores.

Conclusion:

The SDLR of nurse learners in Sri Lanka was influenced not only by learning-related factors but also by working-related factors. Therefore, it is necessary to develop multidimensional strategies to strengthen nurses' SDLR. [

Mindfulness as an Intervention for Depression
Authors: Metcalf Christina A. , Gold Alexandra K. , Davis Brett J. , Sylvia Louisa G. , Battle Cynthia L.
Published: January 2019

Mindfulness-based interventions (MBIs) for depression have become a frequent focus of research and clinical practice in recent decades. This article summarizes evidence regarding the use of MBIs in the prevention of depressive episodes and relief of depressive symptoms across different phases of depression. Much of the review is focused on evidence for mindfulness-based cognitive therapy (MBCT), a widely studied MBI for depression. There is strong evidence for MBCT in preventing depressive relapse among people with recurrent depression in remission. The evidence is less robust and consistent with respect to MBCT as a treatment for acute depression and treatment refractory depression. For some populations of people who are depressed, particularly those who prefer alternatives to antidepressant medications, MBIs may provide an adjunctive treatment option. Emerging work on MBIs suggests that online and other mobile health strategies may be used in the future.

Regional Anesthesia With Monitored Anesthesia Care for Surgical Repair of Selected Open Globe Injuries
Authors: Scott Ingrid U , Gayer Steven , Voo Irene , Flynn Harry W , Diniz Jose R , Venkatraman Anna
Published: January 2019

* BACKGROUND AND OBJECTIVE: To investigate clinical features and visual acuity outcomes associated with the use of regional anesthesia with monitored anesthesia care (RA/MAC) versus general anesthesia for open globe injuries in adult reparable eyes.

* PATIENTS AND METHODS: Retrospective, consecutive case series including all adults with open globe injuries repaired at Bascom Palmer Eye Institute between 2000 and 2003.

* RESULTS: The study included 238 eyes of 238 patients with a median age of 41 years. RA/MAC was employed in 141 (59%) eyes and general anesthesia in 97 (41%) eyes. Patients who had RA/MAC were significantly (P < .001) more likely to have anterior wound location (64% corneal/limbal vs 50%), shorter wound length (6.5 vs 12 mm), and formed anterior chamber (82% vs 56%), and were significantly less likely to have an afferent pupillary defect (12% vs 43%). The improvement from presenting visual acuity to each postoperative follow-up interval was similar for the two groups.

* CONCLUSIONS: RA/MAC is a reasonable alternative to general anesthesia for selected patients with open globe injuries.

Published: January 2019

Abstract. A case of bilateral "drusenoid" pigment epithelial detachment that was studied with fundus fluorescein angiography and optical coherence tomography is described. Fundus fluorescein angiography depicted staining of the drusen without any sign of pooling of the dye, whereas optical coherence tomography displayed detachment of the retinal pigment epithelium. These findings remained unchanged during a 10month period. [Ophthalmic Surg Lasers Imaging 2005;36:147-150.]
HLA-B27-Associated Uveitis With a Chorioretinitis Manifestation
Authors: Lin Jack Yu-Shih , Lin Shun-Ling , Chen Wei-Lin , Chen Ying-Shan
Published: January 2019

Abstract. A 29-year-old man who had been treated for acute anterior uveitis in a local medical office and observed for 1 month presented complaining of distorted vision in his left eye for 1 week. On ophthalmic examination, the anterior segment was relatively quiet with few cells. A posterior segment examination revealed cystoid macular edema and multiple splinter retinal hemorrhages. Results of all laboratory and imaging studies were negative, except for a positive HLAB27 haplotype. Fluorescein angiography revealed massive leakage in the mid and late phase, consistent with chorioretinitis. Periocular corticosteroid injections and oral prednisolone were administered. The patient responded to the treatment well with subsequent resolution of chorioretinitis 2 months later. Although rare, chorioretinitis can occur in the setting of uveitis associated with HLA-B27 and seems to respond well to corticosteroid treatment. [Ophthalmic Surg Lasers Imaging 2005;36:158-162.]

Unambiguous Comparison of Juvenile and Senile Rhegmatogenous Retinal Detachment
Authors: Wu Wei-Chi , Lai Chi-Chun , See Lai-Chu , Tsao Yeou-Ping , Yang Ko-Jen , Chen Tun-Lu
Published: January 2019

* BACKGROUND AND OBJECTIVE: To investigate whether age is a prognostic factor in rhegmatogenous retinal detachment (RRD).

* PATIENTS AND METHODS: The patient population was divided into two groups according to age at onset of RRD (juvenile RRD = younger than 18 years and senile RRD = 65 years and older). The juvenile RRD group consisted of 35 patients and the senile RRD group consisted of 39 patients.

* RESULTS: There were statistically higher incidences of male patients, trauma, subretinal fibrosis, and myopia in the juvenile RRD group compared with the senile RRD group. In addition, there were statistical differences in the break characteristics, extent of RRD, and severity of proliferative vitreoretinopathy between the juvenile and senile RRD groups. However, no statistical differences were evident in the final retinal reattachment rate (88.6% vs 94.9%; P= .413) or the final visual outcome (P = .902) between juvenile RRD and senile RRD.

* CONCLUSION: Clinical characteristics between juvenile and senile RRD are different. Although delayed diagnosis is common, the final surgical outcome in juvenile RRD is as promising as in senile RRD.

A Cluster of Patients With Acute-Onset Endophthalmitis Following Cataract Surgery
Authors: Chaudhry Nauman A , Lavaque Alejandro J , Scott Ingrid U , Flynn Harry W , Liggett Peter E
Published: January 2019

* BACKGROUND AND OBJECTIVE: To describe a cluster of patients who had acute-onset endophthalmitis following cataract surgery.

* PATIENTS AND METHODS: Ten patients with endophthalmitis following cataract surgery who were referred from three different anterior segment surgeons were evaluated.

* RESULTS: Presenting visual acuities ranged from 20/30 to light perception (median, 20/80). All 10 eyes demonstrated vitritis, 8 of 10 eyes had hypopyon, and the remaining 2 eyes had significant anterior segment fibrin. All patients were treated with intravitreal injections of vancomycin and ceftazidime, as well as subconjunctival steroids. Vitreous cultures were positive in 2 of 10 eyes, and both grew Staphylococcus epidermidis; aqueous cultures were negative in 8 of 8 eyes (not performed in 2 patients). Follow-up ranged from 13 to 85 days (median, 37 days). All eyes showed complete resolution of inflammation and visual acuity improved to 20/40 or better in 9 eyes (90%).

* CONCLUSIONS: Acute-onset endophthalmitis may occur in a cluster of patients within a short time frame. Early diagnosis and treatment may result in favorable visual outcomes.

Resolution of Advanced Cystoid Macular Edema Following Photodynamic Therapy for Choroidal Hemangioma
Authors: Shields Carol L , Materin MigueI A , Marr Brian P , Mashayekhi Arman , Shields Jerry A
Published: January 2019

Abstract. A 45-year-old man was referred for 2 months of decreasing vision in his left eye. His visual acuity was 20/200 secondary to a subde juxtapapillary choroidal hemangioma producing profound cystoid macular edema, with the affected retina measuring 330 microns thick by optical coherence tomography. Due to the severe cystoid macular edema, visual prognosis was judged to be poor. One month following photodynamic therapy to the tumor using verteporfin, the cystoid macular edema completely resolved, foveal anatomy returned to normal, optical coherence tomography thickness was 179 microns, and visual acuity recovered to 20/25. Photodynamic therapy of choroidal hemangioma may be effective in resolving associated cystoid macular edema and improving visual acuity. [Ophthalmic Surg Lasers Imaging 2005;36:237-239.]

"Cracked-mud" Ciprofloxacin Precipitates on a Corneal Graft
Authors: Tanhehco Tasha Y , Chiavetta Stephen V , Lee Paul P , Fowler Amy M , Afshari Natalie A
Published: January 2019

Abstract. The authors describe an extreme case of ciprofloxacin deposition on the corneal graft of a 67-year-old man with a history of penetrating keratoplasty for corneal ulcer and perforation, who presented with dense, gray deposits on the anterior corneal surface after being treated with ciprofloxacin for an epithelial defect. The deposits resolved after ciprofloxacin was discontinued. The non-physiologic pH of the drug formulation is thought to trigger corneal precipitates, and it remains to be seen whether fourth-generation fluoroquinolones will have a lower incidence of ocular precipitates.

¿Qué tipo de información transmite el Midrás sobre la sinagoga? Algunas reflexiones a partir de Levítico Rabá
Authors: Miralles-Maciá Lorena
Published: January 2019

Este estudio se centra en los testimonios transmitidos en LvR sobre la sinagoga en la Palestina de la Tardoantigüedad. Su objetivo es doble: 1) determinar el tipo de información sobre la sinagoga según LvR relacionada tanto con el edificio y otros elementos asociados, como con los aspectos litúrgicos, educacionales y comunales; y 2) señalar las dificultades inherentes a la evaluación de esta información, especialmente considerando la escasez de detalles contextuales. Este estudio, por tanto, contribuye a la discusión sobre la conexión entre la sinagoga y el Midrás, arrojando luz sobre la perspectiva de los rabinos sobre esta institución en época amoraíta y su implicación en la vida sinagogal.
Traverser les montagnes du Jura : identification de voies antiques de franchissement de la haute chaîne jurassienne par analyse LiDAR
Authors: Bichet Vincent , Barbier Arthur , Chevassu Valentin , Daval Daniel , Gauthier Émilie , Montandon Murielle , Richard Hervé , Thivet Matthieu
Published: January 2019

La question du franchissement protohistorique ou antique des hauts reliefs du massif du Jura et des incidences des voies de circulation sur le peuplement de cette région frontalière de montagne reste à ce jour mal résolue en raison d’investigations archéologiques peu nombreuses. Les prospections LiDAR aéroportées réalisées dans la région centrale de la haute chaîne (800 à 1 450 mètres d’altitude), à proximité du décrochement de Pontarlier (faille géologique transversale aux plis du relief), ont permis d’identifier les vestiges de trois voies jusqu’à présent supposées ou inédites, susceptibles de correspondre à des axes du réseau routier antique d’Agrippa, reliant la Séquanie à l’Helvétie à travers la montagne jurassienne. Les caractéristiques morphologiques des voies identifiées, comme les premiers éléments de datation établis à partir du mobilier métallique collectés sur deux d’entre elles, paraissent indiquer une fréquentation centrée sur les ier, iie et iiie siècles de notre ère. Le tracé des voies détermine un carrefour qui structure le franchissement du relief selon deux directions : vers la Suisse, depuis Ariolica (Pontarlier) vers Eburodunum (Yverdon), ou vers Lousonna (Lausanne).
La voie de la Doie à Thonon-les-Bains : un témoin de la circulation entre Bas et Haut-Chablais aux premiers temps de l’occupation romaine
Authors: Landry Christophe
Published: January 2019

Des sondages récents ont permis de mettre au jour les vestiges d’une voie romaine au débouché des vallées d’Abondance, d’Aulps et de Bellevaux. Le mobilier découvert dans les premiers comblements du fossé drainant sud permet d’envisager une construction au cours du ier siècle av. J.-C. Son itinéraire à travers le Bas-Chablais pourrait conduire vers les quartiers artisanaux de l’agglomération antique de Thonon. Cette découverte revêt un intérêt certain dans le cadre de la réflexion sur l’existence d’un itinéraire empruntant la rive lémanique méridionale pendant le Haut-Empire. En effet, si aucun chemin antique traversant le massif du Chablais n’est pour l’heure attesté archéologiquement, la voie de la Doie permet de proposer un itinéraire alternatif et plus court que le bord de lac pour rejoindre l’agglomération de FORVM CLAVDII VALLENSIVM, actuelle Martigny.
Franchir les Alpes et les Apennins au début du xviie siècle
Authors: Bayard Françoise
Published: January 2019

À partir du 6 septembre 1607, Jean-Baptiste Duval, avocat au parlement de Paris et secrétaire de la reine, accompagne Jean Bochart, sieur de Champigny, dans son ambassade à Venise. Duval revient en France plus de trois ans plus tard, le 1er octobre 1610. Entre le 23 septembre 1608 et le 22 février 1609, il effectue jusqu’à Naples un périple dans l’Italie centrale. Le 22 septembre 1609, il suit l’ambassadeur en villégiature sur le lac de Garde mais le quitte du 2 au 14 octobre pour visiter l’Italie du Nord. Le manuscrit 13977 du fonds français de la Bibliothèque nationale de France est le journal quotidien de ses faits et gestes. Y sont décrits les itinéraires suivis, les moyens de locomotion et les aides utilisés, les gîtes et les tavernes où l’on s’est arrêté, les caractères géologiques, climatiques, hydrographiques, démographiques, économiques et les mœurs des régions traversées. En a été extrait ce qui relève des circulations dans les Alpes et les Apennins.
Entre allers et retours : approches de l’anthroponymie dans les Pyrénées occidentales (xiiie-xviie siècle)
Authors: Lopetegui Susana Herreros , Vaquero Eloísa Ramírez
Published: January 2019

De part et d'autre des Pyrénées occidentales, l'évolution des noms de famille témoigne entre le xiiie et le xviie siècle de circulations humaines au goutte à goutte mais persistantes en Haute-Navarre. Les riches listes nominatives permettent de poser la question de conversos cherchant à se fondre dans la population. Entre nord et sud de l'ancien royaume de Navarre, on observe le renouvellement de la noblesse, des professions, mais on constate aussi des mouvements inverses sud-nord. Les migrations des Basques catholiques deviennent sensibles après le choix du protestantisme par Jeanne d'Albret. Mais le passage constant dans le temps des éleveurs cadets du Nord suffit à expliquer ces évolutions anthroponymiques lentes.
Laines et draperies des montagnes du Midi français : circulations et productions intra et transpyrénéennes (milieu xviie-début xixe siècle)
Authors: Minovez Jean-Michel
Published: January 2019

À l’époque moderne, le Midi a représenté une des principales zones de production française du textile lainier. Par une analyse fine des catégories, il est possible de reconstituer les choix opérés par les sociétés dans la sélection et la transformation des fibres. Ces opérations s’effectuent dans le cadre d’une grande diversité de la production de laine en France et en Espagne, dans laquelle les montagnes ont occupé une place centrale. L’extraordinaire production espagnole a donné lieu à un commerce intra et transpyrénéen à destination, notamment, des fabriques du midi de la France. L’objectif n’est pas de constituer un catalogue de l’ensemble des lieux d’approvisionnement et de production mais, à travers quelques exemples significatifs, de démontrer la connexion des zones d’approvisionnement et de production à l’origine de la constitution d’un véritable système lainier dans le midi de la France, lui-même générateur d’une organisation économique essentielle au développement de la majorité des sociétés montagnardes et des piémonts.
Analysis of the Stress-Strained State of Billets Processed by Rotary Forging with Special Shape of the Tool
Authors: Asfandiyarov Rashid , Raab Georgy I. , Aksenov Denis
Published: January 2019

In this paper, we investigated the process of rotary forging of commercially pure copper grade M2 ​​using standard and special-shaped anvils and presented the results of studies obtained by the method of numerical and physical modeling. It is established that the use of anvils with special geometric shapes provides a higher level of accumulated strain and the formation of more dispersed structural states with the same elongation ratio under conditions of multi-cycle processing [1]. The formation of a finer structure in its turn increases the hardness and strength of the material. In addition, the special shape of the anvils provides a positive field of values ​​of the Lode-Nadai coefficient in the cross section of the samples, predominantly in a range of 0.3-0.7 and, correspondingly, a more "comfortable" stress state close to non-uniform all-round compression, which contributes to increasing technological plasticity.
Development and Characterisation of New Biocompatible Sn-Mg Lead-Free Solder
Authors: Ďurišin Martin , Ďurišin Juraj , Milkovič Ondrej , Pietriková Alena , Saksl Karel
Published: January 2019

This work is focused on a development and research of a new lead-free Sn-Mg solder, alloy compatible with the human body. Tin and magnesium are biocompatible elements which do not cause an inflammation or allergic reactions with living tissues. We have prepared the Sn97Mg3 solder (wt. %) by a rapid solidification of its melt on a copper wheel (melt-spinning technique). This solder may find applications in electronic devices for intracorporeal utilisation. The microstructure of the prepared solder exhibits a heterogeneous distribution of the SnMg2 intermetallic particles within the β-Sn matrix. Structure of the solder was studied by an in-situ high energy X-ray diffraction experiment (energy of an X-ray photon: 60 keV) where 2D XRD patterns were collected from the sample in the temperature range from 298 K to 566 K. The experiment was performed at a high brilliance 3rd generation synchrotron source of radiation (PETRA III storage ring, DESY, Hamburg, Germany) at the P02 undulator beamline. From the measured X-ray diffraction data by applying the Rietveld refinement technique we have obtained thermal volume expansion data, mean positions of atoms as well as isotropic atomic displacement parameters of the constituent SnMg2 and the β-Sn crystalline phases. Thermal behaviour was studied by differential scanning calorimetry at heating rates of 5, 15, 30 and 60 K.min-1 and compared with the measured X-ray data. Our main goal lies in a preparation of a lead-free solder with fine grain structure made exclusively of biocompatible elements. We demonstrated that the rapid melt solidification technique leads to in an improvement and better thermal stability of this alloy.
Preparation of Poly-Hydrazide and Use as Pour Point Depressor for Heavy Oil
Authors: Peng Seng , Tang Xiao Bin , Wang Hao , Wei Yan , Chen Gang
Published: January 2019

To develop new pour point depressor, in this work, a poly-hydrazide is designed and prepared from vegetable oil, hydrazine hydrate and epichlorohydrin. The effectiveness of the poly-hydrazides on four crude oils was tested as pour point depressants as well as paraffin inhibiters. The results showed that the highest pour point reduction depression was achieved as 9.8°C with 2000ppm PH3O-3 in 2# crude oil. Below the pour point of the crude and processed oils, paraffin crystals will deposit and tend to plug flow lines and filters. The saturated hydrocarbons were separated, and the paraffin crystal morphology studies were conducted to elucidate the mechanism of pour point reduction.

With the demand of modern cutting technology for ‘high efficiency, precise, flexibility and green manufacturing’, polycrystalline diamond materials as cutting tools have been widely used in automobile, aerospace and non-metal processing. Electro-spark erosion is one of the most effective ways to machine polycrystalline diamond materials. Single pulse discharge is one of the research foundations of micro-EDM. Using 2 micron granularity polycrystalline diamond as experiment material, the influence of single pulse discharge technology on the removal efficiency of materials was studied, such as pit radius, pit depth and radius-depth ratio, etc. The experimental results show that, with the extension of the pulse duration, the radius of the discharge pit begins to increase rapidly, then slowly increases, and finally to slow down; while the radius of thermal influence zone increases rapidly and then continues to increase slowly. With the extension of pulse duration, the ratio of pit depth to radius changes within the range of 0.05 ~ 0.25, which shows a downward trend basically.

Published: January 2019

The confined laser shock peening (LSP) is an innovative surface treatment technique designed to improve the fatigue performance of materials by imparting compressive residual stresses into materials. A 3D finite element model was developed to predict the surface residual stress and plastically affected depth of the TC11 titanium alloy after LSP. The modeling procedure consists of two successive explicit analysis steps. The performance of finite element model was verified by comparing simulated results with the experimental data. With the validated finite element model, the influence of the process parameters (LSP path, thickness of the sample, number of impacts) was investigated on the surface residual stress and plastically affected depth of the TC11 titanium alloy after LSP. Some simulated results can be used to mentor the optimization of the process parameters of LSP.

Published: January 2019

The hardness test, Charpy impact test, and axial expansion experiment were performed on a medium carbon steel S35C specimen typically used for shaft materials after first subjecting it to quenching and tempering heat treatment under different heating temperatures/time conditions. The effect of the tempering conditions on the mechanical properties of the specimen and the limit of the diameter-enlarged ratio used for evaluating the workability of the partial diameter-enlarged were investigated. The summary of the results are as follows: after quenching at 880 °C, a fine troostite or sorbite structure was obtained under all heat treatment conditions at heating temperatures of 550 °C to 675 °C, and heating times of 0.5 h to 1.5 h. An improvement was shown in the limit of the diameter-enlarged ratio because the quenching and tempering heat treatment led to an increase in the Charpy impact value/ductility as well as a reduction in the hardness, tensile strength, and yield strength; the partial diameter-enlarged process could be performed on the heat treated material at almost the same deformation speed as a cold-drawn material with a much lower axial pressure; it was possible to estimate the diameter-enlarged deformation behavior using the tempering parameter M. We confirmed that the quenching tempering heat treatment performed in this study facilitates the improvement of the workability of the diameter-enlarged.

Published: January 2019

AbstractThis project examined the feasibility of coupling a mobile ferrate treatment facility with a hydraulic dredge for use in nutrient removal and water quality improvement. The system featured a variable area suction head that was coupled with an inline hydrocyclone and
ferrate treatment system. The project also analyzed the possibility of reuse of the ferrate treatment byproduct as a soil conditioner for plant growth. Testing of the dredging and treatment processes was carried out at the C-1 Canal in Malabar, Florida, USA, at a pilot scale, and analyses
were performed in the Water Quality Research Laboratories at the Florida Institute of Technology. Results from testing showed that the utilization of the hydrocyclone/ferrate system was successful in achieving a 70% reduction in the median grain size of dredge slurry, as well as a significant
reduction in ammonium, total suspended solids, and phosphate.

AbstractThe University of Florida's Institute of Food and Agricultural Sciences (UF/IFAS) Florida Master Naturalist Program (FMNP) is an adult environmental education program with more than 450 trained program graduates in St. Lucie County, Florida. It is a collaborative
effort of the UF/IFAS Extension St. Lucie County, St. Lucie County Environmental Resources Department, and partner agencies. Four UF/IFAS Florida Master Naturalist volunteers were recruited and received training and supplies to conduct water quality testing and algae collection in the Indian
River Lagoon as part of the Volunteer Algae Monitoring Program (VAMP). The UF/IFAS research and extension faculty developed VAMP in response to the 2016 harmful algal blooms (HABs) in the Indian River Lagoon that resulted in dramatic impacts on businesses, residents, and visitors in Martin,
St. Lucie, and Indian River counties. These HAB episodes demonstrate the importance of having informed citizen scientists with an understanding of the problems and threats. The VAMP citizen scientists conducted a water quality awareness survey with the general public after proactively scouting
for HABs by collecting samples and conducting water quality testing at three waypoints in the Indian River Lagoon during May to November 2017 (excluding October) and February 2018. They utilized UF/IFAS Water Watch chemistry tests and processed and shipped water samples to the Laughinghouse
Lab at the UF/IFAS Fort Lauderdale Research and Education Center, which conducted algae counts and genetic testing to determine the presence of harmful algae expressing microcystin-producing genes. Test results indicated fluctuating and inconsistent levels of saxitoxin but no indications of
microcystins across the three sites and over time.
Foundational Experiences and Recent Advances in Long-Term Deep-Ocean Borehole Observatories for Hydrologic, Geodetic, and Seismic Monitoring

Published: January 2019

AbstractFor nearly three decades, various phases of the scientific Ocean Drilling Programs have deployed sealed-hole observatories in deep-ocean boreholes for long-term subseafloor monitoring to address a range of hydrologic and geodynamic objectives. We summarize the scientific
motivation for these observatories and review some important early results from those installed in young oceanic crust and subduction zones. We also summarize the evolution of the borehole observatory designs and associated instrumentation, from simple single-interval installations with autonomous
low-rate temperature and pressure monitoring to recent multiple-zone installations with sophisticated downhole instrument packages connected to seafloor cabled networks that provide power and high-rate, real-time data access. We emphasize recent advances, illustrated with example data drawn
mainly from transects of borehole observatories offshore Japan and Cascadia. These examples illustrate the value of borehole observatory data in resolving a wide range of crustal geodynamic responses from long periods of gradual geodetic change and accumulation of stress to episodes of rapid
deformation associated with both seafloor spreading and subduction processes.

Authors: Van Rooy Jacques , Bergamini Ariel , Bisang Irene
Published: January 2019

Background: A Red List of threatened bryophytes is lacking for Africa. The International Union for Conservation of Nature (IUCN) Species Survival Commission (SSC) Bryophyte Specialist Group has recently launched the ‘Top 10 Initiative’ to identify the 10 species on each continent that are at highest risk of extinction.Objectives: The main aim of this paper was to highlight some of the lost or strongly threatened bryophyte species in sub-Saharan Africa and the East African islands and to draw up a Top 10 list for Africa.Method: Lost or threatened species have been identified with the help of experts on the bryoflora of Africa, global and regional Red Lists and taxonomic literature. Each species on this candidate list is discussed at the hand of its taxonomy, distribution, habitat, threat and current global or regional Red List status as far as previously assessed.Results: Fifty bryophyte species, representing 40 genera and 23 families, have been identified as Top 10 candidates. Of these, 29 are endemic to Africa and 21 are restricted to the East African islands. The majority of the candidate species occur in one of eight ‘biodiversity hotspots’ with most species (19) in the Madagascar and the Indian Ocean Islands hotspot.Conclusion: This is the first list of lost or threatened bryophytes for Africa and the first Top 10 list of the IUCN Bryophyte Specialist Group. It represents an important step towards regional and global Red List assessment of bryophytes, thus meeting the targets of the Updated Global Strategy for Plant Conservation 2011–2020 and priorities of The Shenzhen Declaration on Plant Sciences.

Published: January 2019

The dengue situation in the urban setting of Hanoi city, Vietnam, is emerging, focusing on inner districts. Previous studies showed that a dengue vector control program in Hanoi was not effective because of the lack of adequate engagement of the local government authorities, health sector, and community. This implementation research aimed to explore barriers to implementing community engagement in a dengue vector control program in an urban district of Hanoi city. Ten in-depth interviews and 14 focus group discussions were conducted at Lang Thuong, Khuong Thuong, Tho Quan, and Kim Lien wards in Dong Da district, Hanoi city. Data collection was implemented from April to June 2017. All discussions were recorded and transcribed verbatim. Data were analyzed using the content analysis approach. Secondary data from the dengue vector control program reports were used to support the qualitative evidence. We found that the barriers to implementing effective community engagement were as follows: 1) lack of interest and an attitude of dependency on action from the health sector of local people’s committee, 2) lack of enthusiasm of mass organizations and community leaders, 3) overburdened workloads and lack of communication skills from health sector, 4) low awareness and readiness from community, 5) lack of detailed policy guidelines and low enforcement of related policy, and 6) limited budget. Recommended actions should be made to improve the community engagement in the current resource-limited context of Vietnam by both top-down and bottom-up approaches.
Consequences of Pathogen Lists: Why Some Diseases May Continue to Plague Us
Authors: Brett-Major David M. , Racine Trina , Kobinger Gary P.
Published: January 2019

The current strategy used by many funding agencies for determining how money is spent on research to help prevent infectious disease outbreaks is based on pathogen-specific priority lists. Listing disease threats provides focus for business and research planning conducive to specific goals of developing a drug, or a vaccine, or other particular product. But, this singular type of focus has consequences. This perspective explores the consequences of lists, and describes how parallel programming independent of disease lists that address what we need to do to prevent and mitigate emerging disease risks may provide benefits out of reach of a singular focus on what products we need to have.
CFD-Guided Combustion System Optimization of a Gasoline Range Fuel in
a Heavy-Duty Compression Ignition Engine Using Automatic Piston Geometry
Generation and a Supercomputer

Published: January 2019

A computational fluid dynamics (CFD) guided combustion system optimization was
conducted for a heavy-duty diesel engine running with a gasoline fuel that has a
research octane number (RON) of 80. The goal was to optimize the gasoline
compression ignition (GCI) combustion recipe (piston bowl geometry, injector
spray pattern, in-cylinder swirl motion, and thermal boundary conditions) for
improved fuel efficiency while maintaining engine-out NOx within a
1-1.5 g/kW-hr window. The numerical model was developed using the
multi-dimensional CFD software CONVERGE. A two-stage design of experiments (DoE)
approach was employed with the first stage focusing on the piston bowl shape
optimization and the second addressing refinement of the combustion recipe. For
optimizing the piston bowl geometry, a software tool, CAESES, was utilized to
automatically perturb key bowl design parameters. This led to the generation of
256 combustion chamber designs evaluated at several engine operating conditions.
The second DoE campaign was conducted to optimize injector spray patterns, fuel
injection strategies and in-cylinder swirl motion for the best performing piston
bowl designs from the first DoE campaign. This comprehensive optimization study
was performed on a supercomputer, Mira, to accelerate the development of an
optimized fuel-efficiency focused design. Compared to the production combustion
system in the baseline engine, the new combustion recipe from this study showed
significantly improved closed-cycle fuel efficiency across key engine operating
points while meeting the engine-out NOx targets. Optimized piston
bowl designs and injector spray patterns were predicted to provide enhanced
in-cylinder air utilization and more rapid mixing-controlled combustion, thereby
leading to a fuel efficiency improvement. In addition, shifting the engine
thermal boundary conditions toward leaner operation was also key to the improved
fuel efficiency.
