Analysis of V(C, N) nanoparticles in a medium carbon bainitic microalloyed steel and their influence on strengthening
Authors: Rancel Lucia , Gómez Manuel , Medina Sebastián F. , Valles Pilar 
Published: November 2012

Abstract
Continuous cooling transformation diagrams were plotted for a microalloyed steel in dilatometric tests at different cooling rates, and maximum and minimum cooling rates for bainite formation were determined. Austenite grain and bainite packet sizes were measured in three bainitic microstructures obtained by continuous cooling from austenitisation temperatures of 950, 1 050 and 1 150 °C, respectively. The results show that bainitic packet growth cannot exceed the austenite grain boundaries where it has nucleated. V(C, N) particle size was measured using field emission gun scanning electron microscopy and transmission electron microscopy, respectively. Both techniques yielded very similar values, but transmission electron microscopy is preferable due to its higher resolution and the possibility to carry out electron diffraction and dispersive X-ray analyses. The presence of precipitates has contributed to raising the yield strength, which can be predicted by Orowan's expression.
Effects of molecular polarity on nanofluidic behavior in a silicalite
Authors: Lu Weiyi , Kim Taewan , Zhao Cang , Qiao Yu 
Published: November 2012

Abstract
While “like attracts like” is common sense for large surfaces, here we show that in a nanopore the effective solid–liquid interfacial tension can be quite independent of the liquid polartiy. Moreover, as the liquid molecules and ions are confined, their behavior can be either reversible or irreversible, depending on the liquid composition. These unique phenomena can be attributed to the confinement effects and the absence of bulk liquid phase in the nanoenvironment.
The Process of Exiting Vegetarianism: An Exploratory Study
Authors: Menzies Kenneth , Sheeshka Judy 
Published: November 2012

Purpose: The experience, reasons, and contexts associated with leaving vegetarianism were explored. Methods: Interviews were conducted with a convenience sample of 19 ex-vegetarians and 15 continuing vegetarians. Results: Exiting vegetarianism is similar to the process of leaving other important individual identities, including exiting diets containing meat. It is a process, not an event, and partially a response to inconvenience, particularly when the person's table companions were not vegetarians. Major life changes and declines in self-perceived health provided occasions to reassess life choices, including the vegetarian commitment. Ex-vegetarians interpreted their vegetarianism as a transition to a new, healthier diet. Including a comparison group of continuing vegetarians revealed that the ex-vegetarians were more likely to have become vegetarians as a result of concern about the well-being of animals and the environment, not animal rights, a value more difficult to compromise. Conclusions: Exiting processes show the five central food values of taste, health, time, cost, and social relationships undermine people's commitment to a diet chosen largely for moral reasons.
Recurrent pediatric central nervous system low-grade gliomas: the role of surveillance neuroimaging in asymptomatic children

Object
Pediatric low-grade glioma (LGG) is the most common brain tumor of childhood. Except for the known association of gross-total resection and improved survival rates, relatively little is known about the clinical and radiographic predictors of recurrent disease and the optimal frequency of surveillance MRI. The authors sought to determine the clinical and radiographic features associated with recurrent or progressive disease in a single-institutional series of children diagnosed with primary CNS LGG.

Methods
The authors performed a retrospective analysis of data obtained in 102 consecutive patients diagnosed at Rady Children's Hospital–San Diego between 1994 and 2010 with a biopsy-proven LGG exclusive of a diagnosis of neurofibromatosis. Tumor location, patient age, sex, and symptomatology were correlated with tumor progression or recurrence. Magnetic resonance imaging characteristics and neuroimaging surveillance frequency were analyzed in those children with progressive or recurrent disease.

Results
Forty-six of 102 children diagnosed with an LGG had evidence of recurrent or progressive disease between 2 months and 11 years (mean 27.3 months) after diagnosis. In the larger group of 102 children, gross-total resection was associated with improved progression-free survival (p = 0.012). The location of tumor (p = 0.26), age at diagnosis (p = 0.69), duration of symptoms (p = 0.72), histological subtype (p = 0.74), sex (p = 0.53), or specific chemotherapeutic treatment regimen (p = 0.24) was not associated with tumor progression or recurrence. Sixty-four percent of children with recurrent or progressive disease were asymptomatic, and recurrence was diagnosed by surveillance MRI alone. All children less than 2 years of age in whom the tumor was diagnosed were asymptomatic at the time of progression (p = 0.04). Thirteen percent (6 of 46) of the children had disease recurrence 5 years after initial diagnosis; all of them had undergone an initial subtotal resection. Tumor progression was associated with either homogeneous or patchy T1-weighted post–Gd administration MRI enhancement in 94% of the cases (p = 0.0001).

Conclusions
Children diagnosed with recurrent LGG may be asymptomatic at the time of recurrence. The authors' findings support the need for routine neuroimaging in a subset of children with LGGs, even when gross-total resection has been achieved, up to 5 years postdiagnosis. The authors found that T1-weighted MR images obtained before and after Gd administration alone may be sufficient to diagnose LGG recurrence and may represent an effective strategy worthy of further validation in a larger multiinstitutional cohort.
Occipitocervical fusion using a contoured rod and wire construct in children: a reappraisal of a vintage technique
Authors: Klimo Paul , Astur Nelson , Gabrick Kyle , Warner William C. , Muhlbauer Michael S. 
Published: November 2012

Object
Many methods to stabilize and fuse the craniocervical junction have been described. One of the early designs was a contoured (Luque) rod fixated with wires, the so-called Hartshill-Ransford loop. In this study, the authors report their 20-year experience with this surgical technique in children.

Methods
The authors reviewed the medical records of patients 18 years of age or younger who underwent dorsal occipitocervical fusion procedures between March 1992 and March 2012 at Le Bonheur Children's Hospital using a contoured rod and wire construct. Data on basic patient characteristics, causes of instability, neurological function at presentation and at last follow-up, details of surgery, complications, and radiographic outcome were collected.

Results
Twenty patients (11 male) were identified, with a mean age of 5.5 years (range 1–18 years) and a median follow-up of 43.5 months. Fourteen patients had atlantooccipital dislocation, 2 patients had atlantoaxial fracture–dissociations, 2 had Down syndrome with occipitocervical and atlantoaxial instability, 1 had an epithelioid sarcoma from the clivus to C-2, and 1 had an anomalous atlas with resultant occipitocervical instability. Surgical stabilization extended from the occiput to C-1 in 3 patients, C-2 in 6, C-3 in 8, and to C-4 in 3. Bone morphogenetic protein was used in 2 patients. Two patients were placed in a halo orthosis; the rest were kept in a hard collar for 6–8 weeks. All patients were neurologically stable after surgery. One patient with a dural tear experienced wound dehiscence with CSF leakage and required reoperation. Eighteen patients went on to achieve fusion within 6 months of surgery; 1 patient was initially lost to follow-up, but recent imaging demonstrated a solid fusion. There were no early hardware or bone failures requiring hardware removal, but radiographs obtained 8 years after surgery showed that 1 patient had an asymptomatic fractured rod. There were no instances of symptomatic junctional degeneration, and no patient was found to have increasing lordosis over the fused segments. Five (31%) of the 16 trauma patients required a shunt for hydrocephalus.

Conclusions
Despite the proliferation of screw-fixation techniques for craniocervical instability in children, the contoured rod–wire construct remains an effective, less expensive, and technically easier alternative that has been in use for almost 30 years. It confers immediate stability, and therefore most patients will not need to be placed in a halo device postoperatively. A secondary observation in our series was the high (30%) rate of hydrocephalus requiring a shunt in patients with traumatic instability.
Surgical management of radial head luxation in a dog using an external skeletal traction device
Authors: Yeadon R. , Farrell M. , Fitzpatrick N. 
Published: November 2012

SummaryA five-month-old Airedale Terrier was presented with a history of right thoracic limb lameness. Clinical and radiographic examinations revealed caudolateral luxation of the right radial head. Surgical intervention involved an oblique proximal radial osteotomy and gradual craniomedial traction of the radial head using an external skeletal fixator (ESF) incorporating a traction device. The radial head was gradually reduced over 16 days. After radiographic confirmation of appropriate radial head reduction, a consolidation phase followed, with removal of the traction ESF after 24 days. Follow-up radiographs documented remodelling of the radial head. Clinical follow-up three years postoperatively revealed nearly normal ground reaction forces. Activity was unrestricted and there was no requirement for analgesic medications.

Published: November 2012

SummaryObjective: To report the successful management of a suspected infected tibial fracture in a common grey seal.Study design: Case report.Animal: Female common grey seal (Halichoerus grypus), 2 weeks old, 20 kg.Methods: A closed, complete, transverse fracture of the left tibial distal diaphysis was debrided, reduced and stabilized using a string-of-pearls (SOP) locking plate covered with polymethylmethacrylate impregnated with gentamicin. Fracture of the ipsilateral fibula was left untreated. Postoperative radiographs were obtained immediately, and at 10 days, three weeks, and six weeks post-surgery, and a computed tomographic examination was performed 2.5 months post-surgery. A species-specific progressive rehabilitation programme was conducted.Results: Bone healing of both fractures and absence of injury of the distal tibial growth plate were evident on the 2.5 month follow-up examination, and also full range-of-motion of the flipper was preserved and no lameness or difficulty with swimming and hunting were detected. On computed tomography, signs of chronic left coxofemoral and ilial wing trauma were incidentally detected. The seal was released three months postoperatively.Conclusion: A transverse infected distal fracture of the tibia and fibula in a young common grey seal was successfully managed with the combination of single SOP plating of the tibia, local antibiotic release and a specific rehabilitation programme.Clinical relevance: Surgical treatment of a long-bone fracture in a wild immature grey seal was successful with a combination of techniques adapted to the species.
Lalangue en questions
Authors: Simonney Dominique 
Published: November 2012

Résumé Lalangue , néologisme de Lacan, fusionne les signifiants langue et la , donc le nom et l’article qui le désigne. Cette création langagière née de l’emboutissement de deux signifiants a connu depuis son énonciation par Lacan, en novembre 1971, lors d’une conférence à la chapelle de l’hôpital Sainte-Anne, de très larges développements dans son enseignement. Lacan a entre autres précisé qu’il s’agissait de la langue maternelle, celle qui nomme, à travers ses modulations, sa musicalité (penser à la lallation) les premiers objets que rencontre l’enfant. Lalangue échappe, au moins en partie, aux lois du langage (thème développé par J.-C. Milner). Mais il n’y a pas de langue de lalangue : Lacan revient sur la poésie amoureuse de Dante et sur ce qu’il qualifie d’échec à créer une langue nouvelle. Si lalangue est bien faite pour dire une certaine musique (harmonie ?) de l’amour, elle ne se laisse pas dompter par le cadre du langage, qui, lui, dit tout autre chose, à travers ses lois : la règle, la limite, donc la castration. Dès lors, la place de lalangue dans la cure pose question : d’où mon titre. Bien que reprise largement par les analystes, mais dans des acceptions souvent contradictoires, notamment quant à son usage dans la cure, lalangue fait à mon avis quelque peu encore figure d’ ovni (objet vocal non identifié) dans notre champ.
Aharon Appelfeld, lalangue perdue ?
Authors: Wiener Simone 
Published: November 2012

Résumé Lacan propose le terme de lalangue, en un seul mot, en le présentant d’abord comme si c’était un lapsus. Ce qu’il nomme ainsi désigne ce qu’il en est pour chacun de lalangue maternelle en tant qu’elle échappe à la communication. Elle nous affecte et dépasse ce dont on peut rendre compte au titre du langage. Elle fraye entre mot d’esprit, territoire perdu du corps, souvenirs sonores plus ou moins effacés et traces de l’enfance. Je voudrais reprendre « lalangue » à partir de l’histoire de l’écrivain Aharon Appelfeld telle qu’il en fait récit. Il a traversé en effet une expérience radicale de perte de sa langue maternelle, l’allemand, après la disparition de sa mère. Ce phénomène si particulier peut-il nous apprendre quelque chose sur la question de lalangue ? Il semble que la disparition du corps maternel ait soufflé sa parole. Dans la suite de cette perte, il égare l’usage des mots. « Sans langue maternelle, l’homme est un infirme », dit-il. Après la guerre, la vie revient peu à peu pour lui de différentes manières : par la langue, les sensations qu’elle convoque mais aussi par le sommeil et les rêves. Y a-t-il une place pour les rêves dans la théorisation de Lacan sur lalangue ? L’écriture sera-t-elle pour lui une façon de retrouver les traces de son enfance, la voix qui le mène à lalangue ?
Tirer lalangue
Authors: Henry Paul 
Published: November 2012

Résumé Ainsi que l’a posé Jean-Claude Milner il y a déjà fort longtemps, quelque chose échappe à la linguistique conçue comme le projet d’une représentation formalisée ou formalisable de la langue, quelque chose de non représentable et de non formalisable, dont elle ne saurait rendre compte, mais dont elle se voit cependant appelée à restituer les effets dans sa notation : l’énonciation et le sujet qui la supporte. Pour surmonter cette impasse, le linguiste a recours à des artifices d’écriture hétérogènes à sa propre notation. Il ne s’agit pas ici de reprendre l’exposé de ces analyses mais d’explorer la signification et la portée de cette singulière situation. Il ne va pas de soi que, inscrite dans l’axe de ce projet, la linguistique soit néanmoins possible. Dès lors de quoi cela atteste-t-il ? Cette possibilité n’est en rien différente de celle qui permet les mots d’esprit, les jeux de mots, les calembours, les lapsus, la métaphore, la poésie, voire le mot d’ordre ou le slogan, ou encore le travail analytique. Car tout cela passe nécessairement par les formes que la linguistique représente en dehors desquelles rien ne peut se dire ou s’énoncer, alors même qu’elle n’a rien à en dire par elle-même. Que la linguistique soit possible, qu’elle se plie à de la formalisation, indique que les contraintes que la langue impose sont de pure forme. Qu’il y ait métaphore, quand bien même cela se réalise dans la langue, n’en dépend aucunement. Que la métaphore puisse faire signe, c’est-à-dire sens, ne tient qu’à ce qu’un signifiant puisse représenter un sujet pour un autre signifiant, soit donc qu’il ait lalangue, ce par quoi un être puisse être dit parlant. Il s’ensuit que jouer sur lalangue concerne le sujet comme parlêtre et non la langue, ce sujet ponctuel et évanouissant qui peut s’en trouver affecté.
L'homme sans couleurs

Résumé Au petit matin du 27 mars 1926 les carabiniers de la ville de Turin arrêtent un homme : il est confus, suicidaire, très angoissé et ne se souvient pas de son nom. Après un non-lieu judiciaire il est hospitalisé à l’asile pendant un an. Puis sa famille le retrouve : il s’agit d’un professeur de Vérone spécialisé en néo-scolastique, ayant disparu dix ans auparavant pendant la guerre dans les Carpates. Mais les autorités fascistes décident de son destin et lui assignent une autre identité que la sienne, celle d’un malfrat recherché par la police, avec quatre mandats de capture. Les scientifiques convoqués par le pouvoir réalisent des expertises de tout genre. Toutes – mais principalement la très volumineuse expertise psychiatrique – donnent à voir un certain maniement du positivisme.
La « maladie des mots » : Alejandra Pizarnik et Hugo von Hofmannsthal
Authors: Elfakir Véronique 
Published: November 2012

Résumé Peut-on être poète sans toutefois parvenir à habiter pleinement le langage ? Tel est le paradoxe que cet article a pour but d’illustrer à travers la lecture des écrits intimes d’Alejandra Pizarnick et de la célèbre lettre à lord Chandos de l’écrivain Hugo von Hofmannsthal. Pour ces deux auteurs, les mots sont porteurs d’une sorte d’inquiétante étrangeté, que le recours à la poésie est venu en fait redoubler en mettant l’accent principalement sur le signifiant. La pulvérisation du sens propre à la structure poétique, bien loin de leur permettre de pacifier ce réel qui les encombre, n’a fait qu’exacerber son collapsus avec le langage. Ainsi poètes par fatalité, ils ne cesseront d’aspirer à écrire de la prose en un ultime recours pour tenter de se doter d’une assise symbolique en recréant de l’imaginaire et du sens.
The role of honey in healing of bedsores in cancer patients
Authors: Saha Aramita , Chattopadhyay Subrata , Azam Md. , Sur Prabir Kr. 
Published: November 2012

Abstract
Bacground: Honey was used to treat infected wounds as long as 2000 years before bacteria were discovered. It has been reported to have inhibitory action to around 50 species of bacteria and fungi (aspergillus, penicillium). Usually, Metronidazole powder is used in our palliative clinic for wound healing due to low cost & effectivity. Honey is cheap, easily available ingredient with high astringent activity. Objective: Objectives of the study were to find out the effectiveness of Honey in terms of rate of wound healing & pain control in bedsores of cancer patients. Materials and Methods: 40 cancer patients with bedsore wounds were randomly assigned (1:1 ratio i.e. 20 in each arm) for Study Arm (Honey plus Metronidazole powder) and Control Arm (only Metronidazole powder), attending Palliative clinic of our department in between July 2010 to September 2011. Washing of the wound with normal saline done daily before application of above medicaments. Change of posture & soft bed were encouraged in both groups. A pre designed interview proforma, standardised Bates Jensen Wound Assessment Tool and Visual Analogue Pain assessment scale were used to collect and assess data. Results: There was significant difference in wound healing status (F value = 6.523; Critical Difference =14.03, P&nit;0.05) from day 10 and pain reduction also (F value = 6.638 and Critical Difference = 1.667, P&nit;0.05) from day 7 in study arm. Conclusion: Application of honey dressing provides a better wound healing, rapid pain relief in cancer patients with bedsores in palliative settings.
Fluoride levels and osteosarcoma
Authors: Kharb Simmi , Sandhu Ravindra , Kundu Zile Singh 
Published: November 2012

Abstract
Context: Osteosarcoma is a rare malignant bone tumor, commonly occurring in the age group of 10 to 24 years. Recent reports have indicated that there is a link between fluoride exposure and osteosarcoma. Aims: The present study was planned to analyze serum levels of fluoride in patients of osteosarcoma and fluoride content of their drinking water. Settings and Design: The present study was carried out comparing 10 patients of osteosarcoma and 10 healthy volunteers (who served as controls). Materials and Methods: Serum and drinking water fluoride levels were estimated by ion selective electrode. Statistical analysis used: The data were computed as mean ± SD and Student’s t test was applied. Results: Both, the serum and drinking water fluoride levels, were significant by higher in patients with osteosarcoma as compared to controls (P < 0.05, P < 0.001, respectively). Conclusions: These results suggest a link between fluoride exposure and osteosarcoma.
Generalized Frobenius Algebras and Hopf Algebras
Authors: Cristian Iovanov Miodrag 
Published: November 2012

Abstract“Co-Frobenius” coalgebras were introduced as dualizations of Frobenius algebras. We previously showed that they admit left-right symmetric characterizations analogous to those of Frobenius algebras. We consider the more general quasi-co-Frobenius (QcF) coalgebras. The first main result in this paper is that these also admit symmetric characterizations: a coalgebra is QcF if it is weakly isomorphic to its (left, or right) rational dual Rat(C*) in the sense that certain coproduct or product powers of these objects are isomorphic. Fundamental results of Hopf algebras, such as the equivalent characterizations of Hopf algebras with nonzero integrals as left (or right) co-Frobenius, QcF, semiperfect or with nonzero rational dual, as well as the uniqueness of integrals and a short proof of the bijectivity of the antipode for such Hopf algebras all follow as a consequence of these results. This gives a purely representation theoretic approach to many of the basic fundamental results in the theory of Hopf algebras. Furthermore, we introduce a general concept of Frobenius algebra, which makes sense for infinite dimensional and for topological algebras, and specializes to the classical notion in the finite case. This will be a topological algebra A that is isomorphic to its complete topological dual Aν. We show that A is a (quasi)Frobenius algebra if and only if A is the dual C* of a (quasi)co-Frobenius coalgebra C. We give many examples of co-Frobenius coalgebras and Hopf algebras connected to category theory, homological algebra and the newer q-homological algebra, topology or graph theory, showing the importance of the concept.
