OBJECTIVEThe occipital artery (OA) is a frequently used donor vessel for posterior circulation bypass procedures due to its proximity to the recipient vessels and its optimal caliber, length, and flow rate. However, its tortuous course through multiple layers of suboccipital muscles necessitates layer-by-layer dissection. The authors of this cadaveric study aimed to describe a landmark-based novel anterograde approach to harvest OA in a proximal-to-distal “inside-out” fashion, which avoids multilayer dissection.METHODSSixteen cadaveric specimens were prepared for surgical simulation, and the OA was harvested using the classic (n = 2) and novel (n = 14) techniques. The specimens were positioned three-quarters prone, with 45° contralateral head rotation. An inverted hockey-stick incision was made from the spinous process of C-2 to the mastoid tip, and the distal part of the OA was divided to lift up a myocutaneous flap, including the nuchal muscles. The OA was identified using the occipital groove (OG), the digastric muscle (DM) and its groove (DG), and the superior oblique muscle (SOM) as key landmarks. The OA was harvested anterogradely from the OG and within the flap until the skin incision was reached (proximal-to-distal technique). In addition, 35 dry skulls were assessed bilaterally (n = 70) to study additional craniometric landmarks to infer the course of the OA in the OG.RESULTSThe OA was consistently found running in the OG, which was found between the posterior belly of the DM and the SOM. The mean total length of the mobilized OA was 12.8 ± 1.2 cm, with a diameter of 1.3 ± 0.1 mm at the suboccipital segment and 1.1 ± 0.1 mm at the skin incision. On dry skulls, the occipitomastoid suture (OMS) was found to be medial to the OG in the majority of the cases (68.6%), making it a useful landmark to locate the OG and thus the proximal OA.CONCLUSIONSThe anterograde transperiosteal inside-out approach for harvesting the OA is a fast and easy technique. It requires only superficial dissection because the OA is found directly under the periosteum throughout its course, obviating tedious layer-by-layer muscle dissection. This approach avoids critical neurovascular structures like the vertebral artery. The key landmarks needed to localize the OA using this technique include the OMS, OG, DM and DG, and SOM.

OBJECTIVEThe authors conducted this retrospective study to investigate the clinical outcomes of intracranial solitary fibrous tumor (SFT) and hemangiopericytoma (HPC), defined according to the 2016 WHO classification of central nervous system (CNS) tumors.METHODSHistopathologically proven intracranial SFT and HPC cases treated in the period from June 1996 to September 2014 were retrospectively reviewed and analyzed. Two neuropathologists reviewed pathological slides and regraded the specimens according to the 2016 WHO classification. Factors associated with progression-free survival (PFS) and overall survival (OS) were statistically evaluated with uni- and multivariate analyses.RESULTSThe records of 47 patients—10 with SFT, 33 with HPC, and 4 with anaplastic HPC—were reviewed. A malignant transition from conventional SFT to WHO grade III SFT/HPC was observed in 2 cases, and 13 HPC cases were assigned grade III SFT/HPC. Mean and median follow-ups were 114.6 and 94.7 months, respectively (range 7.1–366.7 months). Gross-total resection (GTR) was significantly associated with longer PFS and OS (p = 0.012 for both), and adjuvant radiation therapy versus no such therapy led to significantly longer PFS (p = 0.018). Extracranial metastases to the liver, bone, lung, spine, and kidney occurred in 10 patients (21.3%). Grade III SFT/HPC was strongly correlated with the development of extracranial metastases (p = 0.031).CONCLUSIONSThe 2016 WHO classification of CNS tumors reflected the different types of pathological malignant progression and clinical outcomes better than prior classifications. Gross-total resection should be the primary treatment goal in patients with SFT/HPC, regardless of the pathological grade, and radiation can be administered as adjuvant therapy for patients with SFT/HPC that shows an aggressive phenotype or that is not treated with GTR.

An experiment was conducted at Jute Research Regional Station (JRRS) of Bangladesh Jute Research Institute (BJRI), Kishoreganj during August 2009 to January 2010 to determine the effect of different plant growth regulators on seed yield and quality of olitorius jute using late jute seed production technique. The experiment was laid out in a randomized complete block design (RCBD) with four replications. Seven growth regulators with different brand names such as Bionik, Litosen, Okozim, Mirakulan, Planovit, Flora and Yield were used in the experiment. All the yield contributing characters increased due to the application of growth regulators over the control. The highest seed yield (2.91g/plant) was obtained with Bionik which was followed by Mirakulan> Okozim> Litosen> Planovit> Yield> Flora> control. The highest of 33.49% seed yield was found in Bionik over control. In terms of quality of seeds, the plant growth regulator `Bionik’ performed the best.The Agriculturists 2017; 15(2) 115-121
In Vivo Evaluation of Biodegradability and Biocompatibility of Fe30Mn Alloy
Authors: Heiden Michael , Stanciu Lia , Nauman Eric , Jones-Hall Yava , Breur Gert , Traverson Marine 
Published: January 2018

Objectives This study aims to evaluate the biodegradability and biocompatibility of an alloy of iron and manganese (Fe30Mn) in a bone model in vivo.
Methods Resorption of a Fe30Mn wire was compared with traditional permanent 316L stainless steel (SS) wire after bilateral transcondylar femoral implantation in 12 rats. Evaluation of biodegradation over 6 months was performed using radiography, post-mortem histology and microscopic implant surface analysis.
Results Corrosion and resorption of the novel iron-manganese implant with formation of an iron oxide corrosion layer was noted on all post-mortem histological sections and macroscopic specimens (corrosion fraction of 0.84 and 0 for Fe30Mn and 316L SS, respectively). Increased bone ongrowth was observed at the wire-bone interface (bone ongrowth fraction of 0.61 and 0.34 for Fe30Mn and 316L SS, respectively). Occasionally, poorly stained newly formed bone and necrotic bone in contact with corrosion was seen. In bone marrow, Fe30Mn alloy was scored as a mild local irritant compared with 316L SS (biocompatibility score of 8.8 and 5.3, respectively). There was no evidence of systemic adverse reaction.
Clinical Significance Resorbable iron-manganese alloys may offer a promising alternative to permanent metallic implants. Further in vivo studies to control implant resorption at a rate suitable for fracture healing and to confirm the biocompatibility and biosafety of the resorbable Fe30Mn metallic implant are necessary prior to use in clinical settings.

Published: January 2018

Objectives Comparison of PennHIP and a novel method to diagnose hip laxity, called the Vezzoni modified Badertscher distension device technique.
Methods In a total of 10 dogs, it was first assessed whether the distraction index (DI) from the PennHIP evaluation center could be reproduced by two individual observers. In the next two steps, the DI measurements made by the individual observers and the PennHIP evaluation center were compared with the laxity index (LI) measured on the Vezzoni modified Badertscher distension device view. Finally, the interobserver agreement of the DI, LI and Norberg angle was assessed and compared with classification criteria.
Results The results were similar for the first three comparisons: there was no evidence for bias, the relation between DI and LI was linear and the variability was small. A comparison of the interobserver agreement showed that the measurement variability for the NA was substantial, while the reproducibility for the DI and LI was equal.
Clinical Significance While the standard ventrodorsal hip extended radiograph is most commonly used for diagnosis and screening of canine hip dysplasia, it lacks sensitivity to diagnose laxity. To improve the identification of hip joint laxity, distraction-based radiographic techniques are helpful. The Vezzoni modified Badertscher distension device technique allows for a reliable in-house evaluation of canine hip joint laxity.
Spatially Resolved Sub-millimeter Continuum Imaging of Neptune with ALMA
Authors: Iino Takahiro , Yamada Takayoshi 
Published: January 2018

Abstract
This paper reports the result of spatially resolved 646 GHz sub-millimeter imaging observation of Neptune obtained by the Atacama Large Millimeter and sub-millimeter Array. The observation was performed in 2012 August as the flux calibration and synthesized beam size were small enough to resolve Neptune’s disk at this time. This analysis aims to constrain the vertical structure of deep and upper-tropospheric South polar hot spot detected previously with mid-IR, millimeter, and centimeter wavelength. The probed atmospheric pressure region estimated by the radiative-transfer method was between 1.0 and 0.6 bar for the nadir and South pole views, respectively. The South polar hot spot was not detected clearly with an uncertainty of 2.1 K. The apparent discontinuity of tropospheric and stratospheric hot spot may be caused by the vertical wind shear of South polar zonal jet.
Intra-cluster Globular Clusters in a Simulated Galaxy Cluster
Authors: Ramos-Almendares Felipe , Abadi Mario , Muriel Hernán , Coenda Valeria 
Published: January 2018

Abstract
Using a cosmological dark matter simulation of a galaxy-cluster halo, we follow the temporal evolution of its globular cluster population. To mimic the red and blue globular cluster populations, we select at high redshift

two sets of particles from individual galactic halos constrained by the fact that, at redshift z = 0, they have density profiles similar to observed ones. At redshift z = 0, approximately 60% of our selected globular clusters were removed from their original halos building up the intra-cluster globular cluster population, while the remaining 40% are still gravitationally bound to their original galactic halos. As the blue population is more extended than the red one, the intra-cluster globular cluster population is dominated by blue globular clusters, with a relative fraction that grows from 60% at redshift z = 0 up to 83% for redshift

. In agreement with observational results for the Virgo galaxy cluster, the blue intra-cluster globular cluster population is more spatially extended than the red one, pointing to a tidally disrupted origin.
The Distribution and Ages of Star Clusters in the Small Magellanic Cloud: Constraints on the Interaction History of the Magellanic Clouds

Abstract
We present a new study of the spatial distribution and ages of the star clusters in the Small Magellanic Cloud (SMC). To detect and estimate the ages of the star clusters we rely on the new fully automated method developed by Bitsakis et al. Our code detects 1319 star clusters in the central 18 deg2 of the SMC we surveyed (1108 of which have never been reported before). The age distribution of those clusters suggests enhanced cluster formation around 240 Myr ago. It also implies significant differences in the cluster distribution of the bar with respect to the rest of the galaxy, with the younger clusters being predominantly located in the bar. Having used the same setup, and data from the same surveys as for our previous study of the LMC, we are able to robustly compare the cluster properties between the two galaxies. Our results suggest that the bulk of the clusters in both galaxies were formed approximately 300 Myr ago, probably during a direct collision between the two galaxies. On the other hand, the locations of the young (≤50 Myr) clusters in both Magellanic Clouds, found where their bars join the H i arms, suggest that cluster formation in those regions is a result of internal dynamical processes. Finally, we discuss the potential causes of the apparent outside-in quenching of cluster formation that we observe in the SMC. Our findings are consistent with an evolutionary scheme where the interactions between the Magellanic Clouds constitute the major mechanism driving their overall evolution.
“Twisting” Motions in Erupting Coronal Pseudostreamers as Evidence for Interchange Reconnection
Authors: Wang Y.-M. , Hess P. 
Published: January 2018

Abstract
Using white-light observations from the COR1 coronagraph during 2008–2013, we have identified ∼50 eruptive events in which a narrow streamer structure appears to rotate about its radial axis as it rises into the field of view beyond

. Extreme-ultraviolet images and potential-field extrapolations suggest that most of these eruptions involve one arcade of a double-lobed pseudostreamer, which is surrounded by open flux of a single polarity. The “twisting” is manifested by the cavity of the erupting lobe, which evolves from a circular to a narrowing oval structure as it is ejected nonradially in the direction of the original X-point. At the same time, the loop legs on the trailing side of the rising cavity/flux rope expand and straighten out, starting at the outer edge of the lobe and progressing inward; this asymmetric opening-up contributes to the impression of a three-dimensional structure twisting away from the observer. On the leading side of the lobe, collapsing cusps are sometimes detected, suggesting the presence of a current sheet where the cavity loops reconnect with the oppositely directed open flux from the adjacent coronal hole. In some events, the inner loops of the cavity/flux rope may continue to expand outward without undergoing interchange reconnection. The transfer of material to open field lines, as well as the lateral confinement of the pseudostreamer by the surrounding coronal holes, acts to produce a relatively narrow, fan-like ejection that differs fundamentally from the large, bubble-shaped ejections associated with helmet streamers.

Abstract
The astronomical gas-phase detection of simple species and small organic molecules in cold pre-stellar cores, with abundances as high as ∼10−8–10−9
n
H, contradicts the generally accepted idea that at 10 K, such species should be fully frozen out on grain surfaces. A physical or chemical mechanism that results in a net transfer from solid-state species into the gas phase offers a possible explanation. Reactive desorption, i.e., desorption following the exothermic formation of a species, is one of the options that has been proposed. In astronomical models, the fraction of molecules desorbed through this process is handled as a free parameter, as experimental studies quantifying the impact of exothermicity on desorption efficiencies are largely lacking. In this work, we present a detailed laboratory study with the goal of deriving an upper limit for the reactive desorption efficiency of species involved in the CO–H2CO–CH3OH solid-state hydrogenation reaction chain. The limit for the overall reactive desorption fraction is derived by precisely investigating the solid-state elemental carbon budget, using reflection absorption infrared spectroscopy and the calibrated solid-state band-strength values for CO, H2CO and CH3OH. We find that for temperatures in the range of 10 to 14 K, an upper limit of 0.24 ± 0.02 for the overall elemental carbon loss upon CO conversion into CH3OH. This corresponds with an effective reaction desorption fraction of ≤0.07 per hydrogenation step, or ≤0.02 per H-atom induced reaction, assuming that H-atom addition and abstraction reactions equally contribute to the overall reactive desorption fraction along the hydrogenation sequence. The astronomical relevance of this finding is discussed.
L’attentat de Charlie Hebdo du point de vue d’élèves dits « musulmans »
Authors: Simon Alice 
Published: January 2018

L’article présente les résultats d’une enquête menée dans une école primaire ségréguée, peu après les attentats de Charlie Hebdo : des entretiens avec des élèves qui se disent « musulmans » montrent que cette perception d’eux-mêmes est saillante dans leur interprétation des événements. Les enfants réagissent de façon hétérogène à la « lecture républicaine » défendue par leur école et notamment à l’injonction d’« être Charlie ». L’article suggère que le contexte de domination scolaire, auquel s’ajoute celui de la minoration sociale et ethnoraciale, doit être pris en compte pour comprendre les prises de position des enfants.
Repenser les situations complexes dans l’enseignement à partir d’un programme de recherche en anthropologie culturaliste : une étude de cas en EPS

Published: January 2018

Le développement de l’approche par les compétences dans l’enseignement favorise la réflexion sur la conception et la mise en œuvre de situations dites « complexes » associées à des situations plus « ciblées ». Cette étude de cas longitudinale vise à analyser l’activité d’un enseignant d’éducation physique et sportive et d’élèves engagés dans une démarche d’enseignement articulant ces deux types de situations. D’un point de vue théorique, elle s’appuie sur une conceptualisation de l’enseignement établie à partir d’un programme de recherche en « anthropologie culturaliste » inspiré de la philosophie analytique de Wittgenstein (2004). À partir de données d’enregistrement de leçons et d’auto confrontations de l’enseignant et d’un élève, les résultats tendent à montrer que la complexité de ce qui se joue dans l’activité réellement déployée par l’enseignant et les élèves en classe est irréductible à la formalisation de situations définies a priori comme « ciblée » ou « complexe » et permettent en ce sens de venir discuter la notion même de complexité.
Du hèrôs au theos . Étude comparée de la double nature et de la diffusion du culte d’Amphiaraos et d’Asclépios
Authors: Piguet Émilie 
Published: January 2018

Le choix d’étudier conjointement Amphiaraos et Asclépios procède d’abord de la volonté d’honorer la mémoire de Pierre Sineux qui leur a, tout au long de sa carrière, porté une attention toute particulière. Il a su mettre en évidence les analogies et les différences qui existent au niveau des pratiques cultuelles et de la place occupée par le rite de l’incubation. Nous souhaitons ici prolonger ses réflexions en abordant, dans une perspective comparatiste, la double identité, héroïque et divine, d’Amphiaraos et d’Asclépios aux époques archaïque et classique. Les questions du cheminement mythique des deux personnages et de l’implantation et de la diffusion des deux cultes seront successivement abordées, à la fois pour faire ressortir les similitudes et les spécificités propres à chacun et pour montrer dans quel contexte s’est opérée à chaque fois leur actualisation.
El trabajo de las mujeres en la Roma antigua. Reflexiones sobre género y economía
Authors: Medina Quintana Silvia 
Published: January 2018

Résumé L’objectif de ce texte n’est pas d’évoquer des métiers concrets exercés par des femmes dans la société romaine mais de mener une réflexion sur le travail féminin et la complexité de l’envisager comme un objet d’étude. Alors qu’il était absent de l’historiographie il y a encore quelques dizaines d’années, on essaie actuellement de revaloriser le rôle économique que les femmes jouèrent dans le passé ; c’est pourquoi on fait référence aussi bien à des analyses historiques qu’économiques et sociologiques. Dans cette étude, on approfondit la recherche autour de certains termes liés au travail féminin et l’on établit une comparaison avec d’autres époques historiques afin d’envisager le travail des femmes dans la Rome antique.
Antiquité en musique : Gounod, Massenet, Saint-Saëns
Authors: Giroud Vincent 
Published: January 2018

Cette contribution examine, dans une perspective comparatiste, les apports de trois grands compositeurs français du dix-neuvième siècle au retour à l’Antiquité grecque comme source d’inspiration théâtrale : Ulysse de Gounod (1852), musique de scène pour la tragédie néoclassique de François Ponsard, montée par la Comédie-Française : Les Érinnyes de Massenet (1872), écrites pour accompagner la version de l’ Orestie par Leconte de Lisle, et dont le succès a entraîné une expansion considérable à la reprise de 1876 ; et l’ Antigone de Saint-Saëns (1893), pour la version de la pièce de Sophocle par Paul Meurice et Auguste Vacquerie, et prétendument une approche musicale plus « authentique ».
L’opposition langue parlée / langue écrite dans la linguistique historique de tradition française (1860-1930)
Authors: Combettes Bernard 
Published: January 2018

Le but de cet article est d’analyser comment la dichotomie langue parlée / langue écrite a été traitée dans les travaux des débuts de la linguistique historique en France – à la fin du xix e siècle et dans le premier quart du xx e siècle. En observant plus particulièrement le rôle qui est accordé à cette opposition dans le changement linguistique, on constatera qu’il est pertinent de distinguer deux grands courants de pensée, qui débouchent sur des approches sensiblement différentes : la tradition de la linguistique française et celle de la linguistique générale. La première ne parvient pas à exploiter les voies novatrices tracées par Paris et par M. Bréal, et se caractérise par une certaine mise à l’écart de la langue orale ; la seconde, représentée par des saussuriens, comme C. Bally ou A. Sechehaye et par les indo-européanistes, comme A. Meillet, prend mieux en compte la spécificité de la langue parlée.
À quoi tiennent les changements des noms d’humains généraux ? L’exemple de mec(s) et gars
Authors: Cappeau Paul , Schnedecker Catherine 
Published: January 2018

Dans cette étude, nous cherchons à vérifier si des noms tels que mec(s) et gars peuvent être considérés comme des noms humains généraux. Nous utilisons les dictionnaires pour observer les définitions et nous interroger sur les options d’analyse retenues. Nous travaillons aussi à partir de gros corpus écrits et oraux pour mieux connaître l’usage contemporain et disposer de contextes récurrents. Plusieurs facteurs jouent un rôle important comme le pluriel ( vs le singulier), les adjectifs associés, les emplois appellatifs et l’élargissement à des référents féminins.
