Les lueurs sombres de la ZAD de Sivens
Authors: Xardel Victoria , Berlan Aurélien 
Published: November 2015

Les récentes luttes d’occupation de zones à défendre (ZAD) ont pris l’an dernier à Sivens un tour tragique. Rémi Fraisse, jeune militant amoureux de la nature, a trouvé la mort sous les grenades des forces de gendarmerie, dont on ne voit pas très bien ce qu’elles cherchaient à protéger, alors même que leur intervention se faisait à l’appel des « aménageurs » du territoire du Testet. À travers trois extraits de la publication qui a accompagné l’intense semaine de mobilisation fin octobre l’an dernier à Sivens, la revue Mouvements 1 a voulu donner à lire les chroniques ordinaires de luttes extraordinaires. Et rendre hommage à Rémi Fraisse.

Jean-Claude Balbot s’est installé dans les Monts d’Arrée en Bretagne dans les années 1970. Son parcours de paysan sur des terres de quévaise est nourri d’engagements multiples : squat de terres, travail social, création d’une école publique bilingue notamment, mais aussi engagement à la Confédération paysanne et au sein du réseau des Civam. Cet itinéraire nous permet de comprendre qu’en matière de luttes politiques en milieu rural, il est urgent non seulement de ne pas baisser la garde, mais de continuer le combat.

ABSTRACT

Introduction
The surface free energy of conditioned-dentin is one of the factors that interfere with monomeric infiltration of the interfibrillar spaces. Saturation of the tooth matrix with different substances may modulate this energy and, consequently, the wettability of the dentin.

Aim
To evaluate the influence of different substances used to saturate conditioned-dentin on surface free energy (SFE) of this substrate.

Materials and methods
Dentin blocks (4 × 7 × 1 mm, n = 6/ group), obtained from the roots of bovine incisors, were etched using phosphoric acid for 15 seconds, rinsed and gently dried. The surfaces were treated for 60 seconds with: ultra-purified water (H2O-control); ethanol (EtOH), acetone (ACT), chlorhexidine (CHX), ethylenediaminetetraacetic acid (EDTA); or sodium hypochlorite (NaOCl). The tooth surfaces were once again dried with absorbent paper and prepared for SFE evaluation using three standards: water, formamide and bromonaphthalene. Analysis of variance (ANOVA) and Dunnet's tests (α = 0.05) were applied to the data.

Results
Ethylenediaminetetraacetic acid was the only substance that caused a change to the contact angle for the standards water and formamide, while only EtOH influenced the angles formed between formamide and the dentin surface. None of the substances exerted a significant effect for bromonaphthalene. In comparison to the control, only EDTA and NaOCl altered both polar components of the SFE. Total SFE was increased by saturation of the collagen matrix by EDTA and reduced when NaOCl was used.

Conclusion
Saturation of the collagen matrix by EDTA and EtOH changed the surface free energy of the dentin. In addition, the use of NaOCl negatively interfered with the properties evaluated.

Clinical significance
The increase of surface free energy and wettability of the dentin surface would allow higher penetration of the the adhesive system, which would be of importance to the clinical success of resin-dentin union.

Randomized Controlled Trial comparing Dressing and No Dressing of Surgical Wound after Cleft Lip Repair
Authors: Gbolahan Olalere Omoyosola , Ogunmuyiwa Stella Amiede , Osinaike Babatunde Babasola 
Published: November 2015

ABSTRACT

Background
Cover wound dressings are regarded as important postoperative care following surgical intervention. Opinions differ on whether the cleft lip repair wound should be routinely covered by dressings or not. Therefore, a well designed randomized controlled trial is required to determine if routine cover dressing offers a better outcome.

Aim
The aim of this study was to compare the outcome of wound and cosmetic appearance of cleft lip repair in a randomized controlled trial between cover wound and no wound dressing groups.

Materials and methods
Forty consecutive patients requiring cleft lip repair were randomized prospectively to receive the traditional wound dressing cover (n = 20) or had the wound left exposed without any dressing cover (n = 20), after the completion of cleft wound closure. The main outcome measures were wound infection and dehiscence rates in the two groups, in addition to the scar cosmetic outcomes.

Result
The two groups were comparable in terms of age and sex. The incidence of wound infection was 0% (0/20) in cover dressing group as compared to 5% (1/20) in no cover dressing group (p = 0.31). No statistical significant differences in the wound dehiscence rate between the wounds that received dressing (15%) and those with no dressing (20%) were observed. The mean diameter of scar at the 5th to 8th week review appointments was almost similar between the group with dressing (3.29 ± 1.26 mm) and no dressing (3.62 ± 1.28 mm). The patient reported outcome in relation to the cosmetic appearance of the scar after repair was similar in the two groups.

Conclusion
There was no difference in the main outcome measures between the group that had cover dressing and those with exposed wound after cleft lip repair surgery. This study demonstrates that dressing of cleft repair wound may be unnecessary.

Biomarkers of Orthodontic Tooth Movement in Gingival Crevicular Fluid: A Systematic Review
Authors: Alhadlaq Adel M 
Published: November 2015

ABSTRACTBackgroundThe analysis of gingival crevicular fluid (GCF) may be an acceptable way to examine the ongoing biochemical processes associated with bone turnover during orthodontic tooth movement. If it is possible to biologically monitor and predict the outcome of orthodontic forces, then the management of appliances could be based on individual tissue responses, and the effectiveness of the treatment could be improved.MethodologyA literature search was carried out in major databases, such as medline, EMBASE, cochrane library, web of science, google scholar and scopus for relevant studies. Publications in English between 2000 and 2014 which estimated GCF markers as indicators of orthodontic tooth movement were included.ResultsThe list of biomarkers available to date was compiled and presented in table format. Each biomarker is discussed separately based on the available evidence.ConclusionSeveral sensitive GCF markers are available to detect the biomechanical changes occurring during orthodontic tooth movement. Further focused research might help to analyze the sensitivity and reliability of these indicators, which in turn can lead to the development of chairside tests to assess the outcome of orthodontic therapy.How to cite this articleAlhadlaq AM.

ABSTRACT

Aim
The aim of this study is to present a literature review on the effects of the ionizing radiation from radiotherapy treatment on dental tissues.

Background
Among the effects of increasing global life expectancy and longevity of the teeth in the oral cavity, increasing rates of neoplastic diseases have been observed. One of the important treatment modalities for head and neck neoplastic diseases is radiotherapy, which uses ionizing radiation as the main mechanism of action. Therefore, it is essential for dentists to be aware of the changes in oral and dental tissues caused by ionizing radiation, and to develop treatment and prevention strategies.

Results
In general, there is still controversy about the effects of ionizing radiation on dental structures. However, qualitative and quantitative changes in saliva and oral microbiota, presence of oral mucositis and radiation-related caries are expected, as they represent the well-known side effects of treatment with ionizing radiation. Points that still remain unclear are the effects of radiotherapy on enamel and dentin, and on their mechanisms of bonding to contemporary adhesive materials.

Conclusion
Ionizing radiation has shown important interaction with organic tissues, since more deleterious effects have been shown on the oral mucosa, salivary glands and dentin, than on enamel.

Clinical significance
With the increasing number of patients with cancer seeking dental treatment before and after head and neck radiotherapy, it is important for dentists to be aware of the effects of ionizing radiation on the oral cavity.

De transactiebeslissing van het auditoraat van de Belgische mededingingsautoriteit in het supermarktendossier: een ‘hub & spoke’ compromis à la belge?
Door middel van zijn eerste transactiebeslissing ooit beëindigde het auditoraat van de Belgische mededingingsautoriteit op 22 juni 2015 een langlopend onderzoek naar retailprijsafspraken tussen supermarkten en hun leveranciers. Ondanks de eerste succesvolle toepassing van deze nieuwe schikkingsprocedure bevestigt de Belgische beslissing bovenal de onzekerheden omtrent de mededingingsrechtelijke beoordeling van ‘hub & spoke’ afspraken alsmede de beperkte reikwijdte van schikkingen als alternatieve instrumenten van mededingingshandhaving.

<p>Entendendo a relevância da Leitura Literária no campo da Literatura e Ensino, neste artigo, promove-se o estudo sobre a concepção de Mikhail Bakhtin a respeito da língua e da interação social na construção da linguagem romanesca, por meio de análises dos textos de Guimarães Rosa, <em>Conversa de Bois </em>(1946) e <em>Campo Geral</em> (1956), utilizando-se como fundamentação teórica, especialmente, o livro <em>Marxismo e Filosofia da Linguagem </em>(1997)<em>, </em>de Mikhail Bakhtin (Volochinov), no qual o autor expõe a sua teoria da linguagem e do dialogismo – diálogo entre o "eu" e o "outro". É esse caráter interativo da linguagem – a relação intersubjetiva entre os sujeitos sociais – que permeia a concepção de linguagem desse autor e que possibilita a análise proposta, tendo em vista que a linguagem na obra de Guimarães Rosa também remete a essa interação. </p>
Can ring current stabilize magnetotail during steady magnetospheric convection?
Authors: Dubyagin S. , Ganushkina N. , Liemohn M. , Kubyshkina M. 
Published: November 2015

AbstractThe present study investigates the role of the ring current in stabilizing the magnetotail during steady magnetospheric convection (SMC) events. We develop a method for estimation of the symmetric ring current intensity from the single spacecraft magnetic field observations. The method is applied to a large number of SMC events identified using three different automatic procedures adopted from the literature. It is found that the symmetric ring current can be weak or strong depending on a particular event. We find a significant fraction of events that have a rather weak symmetric ring current in spite of the strong solar wind driving during the event. These findings imply that the symmetric ring current plays no role in the magnetotail stabilization.

Published: November 2015

AbstractDespite extensive efforts into characterization of the sources and formation mechanisms of severe haze pollution in the megacity of Beijing, the response of aerosol composition and optical properties to coal combustion emissions in the heating season remain poorly understood. Here we conducted a 3 month real‐time measurement of submicron aerosol (PM1) composition by an Aerosol Chemical Speciation Monitor and particle light extinction by a Cavity Attenuated Phase Shift extinction monitor in Beijing, China, from 1 October to 31 December 2012. The average (±σ) PM1 concentration was 82.4 (±73.1) µg/m3 during the heating period (HP, 15 November to 31 December), which was nearly 50% higher than that before HP (1 October to 14 November). While nitrate and secondary organic aerosol (SOA) showed relatively small changes, organics, sulfate, and chloride were observed to have significant increases during HP, indicating the dominant impacts of coal combustion sources on these three species. The relative humidity‐dependent composition further illustrated an important role of aqueous‐phase processing for the sulfate enhancement during HP. We also observed great increases of hydrocarbon‐like OA (HOA) and coal combustion OA (CCOA) during HP, which was attributed to higher emissions at lower temperatures and coal combustion emissions, respectively. The relationship between light extinction and chemical composition was investigated using a multiple linear regression model. Our results showed that the largest contributors to particle extinction were ammonium nitrate (32%) and ammonium sulfate (28%) before and during HP, respectively. In addition, the contributions of SOA and primary OA to particle light extinction were quantified. The results showed that the OA extinction was mainly caused by SOA before HP and by SOA and CCOA during HP, yet with small contributions from HOA and cooking aerosol for the entire study period. Our results elucidate substantial changes of aerosol composition, formation mechanisms, and optical properties due to coal combustion emissions and meteorological changes in the heating season.
An updated subgrid orographic parameterization for global atmospheric forecast models
Authors: Choi Hyun‐Joo , Hong Song‐You 
Published: November 2015

AbstractA subgrid orographic parameterization (SOP) is updated by including the effects of orographic anisotropy and flow‐blocking drag (FBD). The impact of the updated SOP on short‐range forecasts is investigated using a global atmospheric forecast model applied to a heavy snowfall event over Korea on 4 January 2010. When the SOP is updated, the orographic drag in the lower troposphere noticeably increases owing to the additional FBD over mountainous regions. The enhanced drag directly weakens the excessive wind speed in the low troposphere and indirectly improves the temperature and mass fields over East Asia. In addition, the snowfall overestimation over Korea is improved by the reduced heat fluxes from the surface. The forecast improvements are robust regardless of the horizontal resolution of the model between T126 and T510. The parameterization is statistically evaluated based on the skill of the medium‐range forecasts for February 2014. For the medium‐range forecasts, the skill improvements of the wind speed and temperature in the low troposphere are observed globally and for East Asia while both positive and negative effects appear indirectly in the middle‐upper troposphere. The statistical skill for the precipitation is mostly improved due to the improvements in the synoptic fields. The improvements are also found for seasonal simulation throughout the troposphere and stratosphere during boreal winter.
Field investigation of dried lakes in western United States as an analogue to desiccation fractures on Mars

Published: November 2015

AbstractPotential Desiccation Polygons (PDPs), tens to hundreds of meters in size, have been observed in numerous regions on Mars, particularly in ancient (>3 Gyr old) terrains of inferred paleolacustrine/playa geologic setting, and in association with hydrous minerals such as smectites. Therefore, a better understanding of the conditions in which large desiccation polygons form could yield unique insight into the ancient climate on Mars. Many dried lakebeds/playas in western United States display large (>50 m wide) desiccation polygons, which we consider to be analogues for PDPs on Mars. Therefore, we have carried out fieldwork in seven of these dried lakes in San Bernardino and the Death Valley National Park regions complemented with laboratory and spectral analysis of collected samples. Our study shows that the investigated lacustrine/playa sediments have (a) a soil matrix containing ~40–75% clays and fine silt (by volume) where the clay minerals are dominated by illite/muscovite followed by smectite, (b) carbonaceous mineralogy with variable amounts of chloride and sulfate salts, and significantly, (c) roughly similar spectral signatures in the visible‐near‐infrared (VIS‐NIR) range. We conclude that the development of large desiccation fractures is consistent with water table retreat. In addition, the comparison of the mineralogical to the spectral observations further suggests that remote sensing VIS‐NIR spectroscopy has its limitations for detailed characterization of lacustrine/playa deposits. Finally, our results imply that the widespread distribution of PDPs on Mars indicates global or regional climatic transitions from wet conditions to more arid ones making them important candidate sites for future in situ missions.
Integrated framework for constrained minimum‐time trajectory generation, fault detection and reconfiguration: A case‐study
Authors: Suryawan Fajar , De Doná José , Seron María 
Published: November 2015

SummaryThis paper provides a unified treatment to the problems of constrained minimum‐time trajectory generation, fault detection and isolation and (after a fault has been detected and identified) trajectory reconfiguration, in an integrated scheme using a differential flatness and B‐splines parameterisation. Using the flatness/B‐splines parameterisation, the problem of minimum‐time constrained trajectory planning is cast into a feasibility‐search problem in the splines control‐points space, in which the constraint region is characterised by a polytope. A close approximation of the minimum‐time trajectory is obtained by systematically searching the end‐time that makes the constraint polytope to be minimally feasible. Fault detection is carried out by using B‐splines in an FIR filter implementation. Thus, the three problems (namely, trajectory generation, fault detection and trajectory reconfiguration), which are traditionally dealt with separately, are solved in a unified manner, using the same mathematical/computational tools. This, not only offers a unified solution but also simplifies the use of mathematical libraries in the coding of algorithms for real‐time applications. All through the paper, a case‐study consisting in a nonlinear input‐constrained double‐tank system is analysed in order to illustrate the techniques in an intuitive manner.

Poly(N‐isopropylacrylamid)‐Phasendiagramme: 50 Jahre Forschung
Authors: Halperin Avraham , Kröger Martin , Winnik Françoise M. 
Published: November 2015

AbstractIm Jahr 1968 publizierten Heskins und Guillet die erste systematische Studie über das Phasendiagramm von Poly(N‐isopropylacrylamid) (PNIPAM), einem zu jener Zeit “jungen Polymer”, das erstmalig 1956 synthetisiert worden war. Seitdem ist PNIPAM zu einem führenden Vertreter der wachsenden Familie temperatur‐ und reizempfindlicher Polymere geworden. Seine thermische Antwort ist fraglos durch sein Phasenverhalten begründet. Nach nunmehr 50 Jahren Forschung zeichnet sich noch immer kein einheitliches, quantitatives Bild seines Verhaltens ab. In diesem Aufsatz treten wir eine Reise zu den beobachteten Phasendiagrammen an. Wir kommentieren theoretische Überlegungen zu den möglichen Ursachen der dabei offensichtlich werdenden Unterschiede. Dabei ist es unser Ziel, nach wie vor offene Fragen auf diesem altehrwürdigen Gebiet vor Augen zu führen.

Authors: Ji Keming , Meng Fanhui , Li Zhong 
Published: November 2015

AbstractA series of xNi@Al2O3 catalysts with different Ni content was prepared by impregnation combustion method, the catalytic performance for CO methanation in a slurry‐bed reactor at low‐temperature was studied, and the structure of the catalysts was characterized by X‐ray diffraction, N2 adsorption–desorption, temperature‐programmed reduction of H2, transmission electron microscope, and H2 chemisorption. The results show that as Ni content increased from 5 to 45%, the crystallite size of metallic Ni increased and the specific surface area decreased, while as the Ni content was between 25 and 45%, the metal Ni surface area firstly increased and was then maintained at around 10 m2·g−1. The catalytic activity of xNi@Al2O3 catalysts increased as the Ni content rose from 5 to 25%, and then remained constant as the Ni content continued to rise. Under the reaction conditions of 300 °C, 1 MPa, and 3000 mL·g−1·h−1, 25Ni@Al2O3 catalyst exhibited the best catalytic performance; the CO conversion and the CH4 selectivity reached 94.3 and 93.7%, respectively. © 2015 Curtin University of Technology and John Wiley & Sons, Ltd.
Improved synthesis and properties of hydroxyl‐terminated liquid fluorosilicone

Published: November 2015

ABSTRACTThe synthesis of hydroxyl‐terminated poly(trifluoropropylmethyl)siloxane (PTFPMS‐OH) by anionic ring‐opening polymerization of 1,3,5‐tris(trifluoropropylmethyl)cyclotrisiloxane (D3F) was studied in bulk using potassium hydroxide as an initiator in the presence of several reaction stabilizers. The promoting effect of the reaction stabilizers for the polymerization of D3F was investigated by GPC and NMR analyses. Results showed that the selected reaction stabilizers exhibited a significant promoting effect. This new process of polymerization produced well‐defined α,ω‐dihydroxylated polysiloxane in very high yields. The addition of reaction stabilizers could almost completely suppress back‐biting reactions during the polymerization. It was found that there lies an exponential decay relationship between the molecular weight of PTFPMS‐OH and amount of end‐capping agent. Thus, by adjusting the reaction conditions strictly, the molecular weight of the fluorosilicone could be controlled accurately, and meanwhile a broad “terminate window” could be implemented. Thermogravimetic (TG) analysis indicated that PTFPMS‐OH could be used in a wide range of operational temperatures. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci.2016,133, 43220.
