Abstract
The effectiveness of spirotetramat in the control of pear psylla (Cacopsylla pyri) on pear trees was investigated in five field experiments, carried out in years 2009- 2011. One or two treatments were applied in June; the first treatment in the early stage of larvae hatching from eggs deposited by females from the summer generation, whilst the second application was carried out about two weeks later. In all the experiments, spirotetramat as Movento 100 SC applied at a dose of 2.25 l/ha effectively reduced the pest population after only a single application (total reduction of larvae after one week post-treatment 75.3-91.4%, and 83.7-97.6% at two weeks posttreatment). Movento 100 SC applied after a single application at a lower dose of 1.8 l/ha had a slightly worse effect (the total reduction of larvae at one week posttreatment was at the level of 58.4-91.3%, and two weeks after application at the level of 56-92.6%) - but in this case only a few larvae at stages L4 and L5 were found on pear shoots. The effectiveness of spirotetramat at both doses after two applications was very high.
In comparison with standard insecticides the efficacy of spirotetramat was higher or not significantly different. In two experiments the application of standard compounds such as diflubenzuron and novaluron was not effective in controlling pear psylla and therefore did not prevent damage to pear trees. This may suggest that local populations of the pest are resistant to these measures, especially since they have been used for many years to control other pests of pear trees
Measurement of strain-rate components in a glacier with embedded inclinometers: numerical analysis
Authors: Jaber Mariam , Blatter Heinz , Picasso Marco 
Published: June 2013

AbstractInclinometry with embedded probes is analyzed with a Stokes model of a solid body floating in a fluid with much smaller viscosity for a two-dimensional flow field. The assumption that such a probe behaves like a Lagrangian unit vector is only justified for probes embedded in a Newtonian fluid with lengths at least four times their width. A fluid with Glen-type rheology results in a slightly smaller rotation rate of the probe compared to Newtonian fluids.

La fonction sensation et la capacité relationnelle qui lui est corrélée peuvent être restaurées grâce à une plongée dans le monde archétypique du patient, celui des images virtuelles n’étant pas animé et restant impersonnel.
Les sciences sociales doivent-elles accumuler les capitaux ?
Authors: Neveu Érik 
Published: June 2013

Le point de départ et l’alibi de cette contribution vient du livre Erotic Capital de Catherine Hakim, qui argumente sur la nécessité théorique de prendre en compte un capital impensé, « érotique », dont les effets s’observent en tous domaines de la vie sociale et dont la légitimation pourrait être une ressource pour les femmes. L’analyse de C. Hakim pose une série de questions sur la singularité réelle de ce capital, la façon dont elle articule son analyse à des travaux déjà existants, la nature de ses usages. Au-delà, son travail invite à questionner le processus inflationniste de multiplication de « capitaux » aux adjectifs variés. Cet article propose de se doter de distinctions conceptuelles claires entre des types élémentaires de capitaux (culturel, économique, social, symbolique) d’une part, et d’autre part, les formes que chacun peut décliner et les combinatoires de ces capitaux élémentaires par lesquelles s’engendrent des capitaux « moléculaires » efficients dans un espace social donné.
« On nous écrit de Rio... » : les frontières transnationales du système médiatique de la presse au xixe siècle
Authors: Caparelli André 
Published: June 2013

Cet article vise à montrer le rôle du journal et des journalistes dans les échanges culturels entre la France et le Brésil au xix e siècle. Des deux côtés de l’Atlantique, la montée en puissance de la presse moderne entraîne des profonds changements dans la production, la diffusion et la réception de la culture. Après un tour d’horizon sur la circulation des « passeurs culturels » français et brésiliens à Rio de Janeiro et à Paris, l’article traite des transferts d’informations et de représentations qui ont lieu dans les journaux et autres périodiques. Ces échanges reflètent non seulement la naissance de la culture médiatique mais aussi la mise en place d’un système médiatique global. À partir de la première moitié du xix e siècle, partout dans le monde, la presse peut être considérée comme le plus important moyen de médiation de la culture, en introduisant une nouvelle « ère médiatique » et en donnant naissance à la globalisation de l’information, qui sont à l’origine du monde médiatique que nous connaissons aujourd’hui.
Un procès improbable : Paris-Soir contre L'Écho Illustré (1938-1939)
Authors: Clavien Alain 
Published: June 2013

En automne 1938, le grand quotidien parisien Paris-Soir intente un procès pour diffamation contre l’hebdomadaire catholique genevois L’Écho Illustré qui l’a traité de « pourrissoir ». L’affaire est plaidée en été 1939 et le journal français est débouté avec pertes et fracas, sous les sarcasmes de la presse locale qui, tous bords politiques confondus, a pris le parti de son confrère catholique. Pour incongru qu’il paraisse, ce procès cristallise l’exaspération grandissante des éditeurs de journaux suisses romands face à la concurrence des journaux français — au point qu’on parle d’« envahissement » et qu’on oppose volontiers un modèle de journalisme national, propre et honnête, à un modèle étranger, peu scrupuleux et porté au sensationnalisme.
Journalistes, responsables politiques et militaires français en Afrique : une information en co-production (1994-2008) ?
Authors: Robinet François 
Published: June 2013

L’analyse des productions médiatiques proposées par une dizaine de rédactions françaises sur quelques grands conflits africains des années 1990-2000 permet d’interroger les liens entre les représentations médiatiques de l’événement et les pratiques journalistiques. Cette approche par les contenus met en évidence de fortes corrélations entre l’intensification de la couverture médiatique, la dramatisation de l’événement et la valorisation du rôle de la France. Mise en perspective à l’aide d’une douzaine d’entretiens avec des journalistes, l’analyse révèle également une mise en scène de l’information sous l’influence des stratégies de communication déployées par la diplomatie française au service d’intérêts nationaux. Dès lors, la fabrique de l’information doit être considérée comme une production, collective et systémique, effectuée par des professionnels confrontés à des contraintes fortes et à des jeux d’influence de plus en plus complexes.

Spherical Geometry HOC Scheme to Capture Low Pressures within a Wake
Authors: Sekhar T. V. S. , Raju B. Hema Sundar 
Published: June 2013

AbstractThe solution of the pressure Poisson equation in spherical polar coordinates using a higher order compact (HOC) scheme effectively captures low pressure values in the wake region for viscous flow past a sphere. In the absence of an exact solution, the fourth-order of accuracy of the results is illustrated. Low pressure circular contours occur in the wake region when the Reynolds number Re = 161, which is a lower value than previously identified in the literature, and closed pressure contours appear in two regions when Re = 250.
Superconvergence of Fully Discrete Finite Elements for Parabolic Control Problems with Integral Constraints
Authors: Tang Y. , Hua Y. 
Published: June 2013

AbstractA quadratic optimal control problem governed by parabolic equations with integral constraints is considered. A fully discrete finite element scheme is constructed for the optimal control problem, with finite elements for the spatial but the backward Euler method for the time discretisation. Some superconvergence results of the control, the state and the adjoint state are proved. Some numerical examples are performed to confirm theoretical results.
Suivi de 3 plantes rares de l’estuaire d’eau douce du Saint-Laurent
Authors: Gilbert Hélène 
Published: June 2013

Trois plantes caractéristiques de l’estuaire d’eau douce du Saint-Laurent et en situation précaire ont fait l’objet d’un suivi annuel de 2008 à 2012 : la gentiane de Victorin (Gentianopsis virgata ssp. victorinii), la cicutaire de Victorin (Cicutamaculata var. victorinii) et l’ériocaulon de Parker (Eriocaulon parkeri). Le suivi a été réalisé entre Saint-Augustin-de-Desmaures et l’île aux Grues, dans 10 sites où au moins un de ces taxons était présent. Un dénombrement a été effectué systématiquement dans chaque site et chaque année, à l’aide de 20 quadrats de 1 m2. Les comparaisons interannuelles ont révélé des variations très importantes chez la gentiane de Victorin, des années d’abondance exceptionnelle étant suivies d’années de quasi-disparition. Ces variations n’ont pas pu être expliquées clairement au terme des 5 années de suivi. Les populations de cicutaire de Victorin se sont généralement maintenues. Les effectifs de l’ériocaulon de Parker ont subi une baisse significative dans les 2 populations sises les plus près de la limite aval et septentrionale de l’aire de répartition ; quant aux 2 autres populations étudiées, l’une est demeurée stable et l’autre s’est accrue.

Published: June 2013

Malgré l’importance confirmée des listes rouges en tant que source d’information pour la conservation adéquate de la biodiversité et alors que de telles listes détaillées existent déjà pour de nombreux groupes tels que les mammifères ou les oiseaux, aucune liste de macromycètes (champignons supérieurs) en situation précaire n’est encore disponible dans la plupart des régions du monde, y compris au Québec. Les écosystèmes forestiers matures semblent abriter de nombreuses espèces rares et devraient par conséquent être inventoriés avec une attention particulière pour fournir des renseignements de base sur la flore macrofongique québécoise. Notre étude avait donc pour objectif de documenter la diversité des macromycètes présents dans une forêt ancienne. Vingt-deux excursions hebdomadaires ont été effectuées entre juin et octobre 2012 dans un écosystème forestier mature exceptionnel, le Boisé-des-Muir. Un total de 333 espèces de macromycètes y ont été identifiées, dont 7 qui étaient inconnues pour la province de Québec. Les genres Lepiota, Cystolepiota et Leucoagaricus étaient exceptionnellement bien représentés. La grande majorité de ces 333 espèces étaient saprotrophiques, confirmant ainsi l’importance des débris ligneux dans de tels écosystèmes. La sous-représentation des espèces mycorhiziennes, malgré une bonne proportion d’espèces rares, est probablement attribuable aux conditions météorologiques propres à l’année d’échantillonnage. En gardant à l’esprit la prudence avec laquelle de tels inventaires doivent être comparés, la présente étude laisse croire que les forêts feuillues matures du sud du Québec présentent une diversité macrofongique élevée.
Isolation of Primary Cilia by Shear Force
Authors: Mitchell Kimberly A. P. 
Published: June 2013

AbstractThe cell's primary cilium is both a mechanical and chemical sensor involved in many signaling pathways. In order to ascertain protein enrichment in the primary cilium or study sub‐ciliary localization of various proteins, it is advantageous to remove the primary cilium from the cell body. The protocol described here gives detailed instructions on purifying primary cilia by separating them from the cell body using shear force. This simple technique avoids using harsh purification conditions that may affect signaling proteins in the cilium or cause the ciliary membrane to disintegrate. In addition, as the cell body remains mostly intact, contamination of the isolated cilia by proteins from the cell body is minimized. This protocol is ideally suited for isolating cilia from renal cell lines, as primary cilia in these cells grow to greater lengths than in other cell types (up to 50‐µm long in Xenopus A6 toad kidney cells as opposed to 1 to 5 µm in NIH3T3 fibroblast cells).

Increasing Accuracy of Video Quality Ratings through Direction of Attention and Training
Authors: Evans Rochelle E. , Kortum Philip 
Published: June 2013

SummaryThis paper describes the results of two studies undertaken to better understand the strong positive relationship between the content of a video clip and viewers' subjective ratings of the video quality of that clip. Experiment 1 evaluated the effect of training on video quality ratings. Experiment 2 assessed the impact of attention in these assessments. Experiment 1 showed that training participants on video quality assessment techniques removed viewers' heuristic reliance on affect while increasing accuracy. Experiment 2 demonstrated that participants' video quality ratings could also be improved by directing their focus of attention. Focusing viewers on quality did not show a moderation of the relationship between content immersion and video quality, as participants maintained high levels of content immersion even when focusing on video quality. Because training and attention increased quality rating accuracy, they could be utilized in video quality testing to improve the viewer feedback received. Copyright © 2013 John Wiley & Sons, Ltd.
Spatially Controlled Delivery of siRNAs to Stem Cells in Implants Generated by Multi‐Component Additive Manufacturing

Published: June 2013

AbstractAdditive manufacturing is a promising technique in tissue engineering, as it enables truly individualized implants to be made to fit a particular defect. As previously shown, a feasible strategy to produce complex multicellular tissues is to deposit different small interfering RNA (siRNA) in porous implants that are subsequently sutured together. In this study, an additive manufacturing strategy to deposit carbohydrate hydrogels containing different siRNAs is applied into an implant, in a spatially controlled manner. When the obtained structures are seeded with mesenchymal stem (stromal) cells, the selected siRNAs are delivered to the cells and induces specific and localized gene silencing. Here, it is demonstrated how to replicate part of a patient's spinal cord from a computed tomography scan, using an additive manufacturing technique to produce an implant with compartmentalized siRNAs in the locations corresponding to distinct tissue. Hydrogel solutions loaded with different siRNA can be co‐printed together with polycaprolactone that acts as rigid mechanical support to the hydrogel. This study demonstrates a new route for the production of 3D functionalized, individualized implants which may provide great clinical benefit.
Diamond Surfaces with Air‐Stable Negative Electron Affinity and Giant Electron Yield Enhancement

Published: June 2013

AbstractThe presence of an air‐stable negative electron affinity (NEA) on lithium‐covered oxygen‐terminated diamond after a thermal activation process is demonstrated. The NEA is unequivocally established by the onset of photoelectron yield at the bandgap energy of 5.5 eV. This surface exhibits a secondary electron yield enhancement by a factor of 200, compared to a surface with positive electron affinity. The surface chemistry leading to the necessary surface dipole was elucidated by core‐level photoemission spectroscopy in conjunction with previous theoretical calculations. The insensitivity to the details of the deposition process opens a route to practical and robust negative‐electron affinity devices based on diamond.
Characterizing the relationship between in‐hospital measures and workers' compensation outcomes among severely injured construction workers using a data linkage strategy
Authors: Ruestow Peter S. , Friedman Lee S. 
Published: June 2013

AbstractBackgroundTo characterize the relationship between acute measures of severity and three important workers' compensation outcomes associated with a worker's ability to return to work and the cost of a work‐related injury.MethodsProbabilistic data linkage of workers' compensation claims made by injured construction workers from 2000 to 2005 with two Illinois medical record registries. Multivariable robust regression models were built to assess the relationship between three in‐hospital measures and three outcomes captured in the Workers' Compensation data.ResultsIn the final multivariable models, a categorical increase in injury severity was associated with an extra $7,830 (95% CI: $4,729–$10,930) of monetary compensation awarded, though not with temporary total disability (TTD) or permanent partial disability (PPD). Our models also predicted that every extra day spent in the hospital results in an increase of 0.51 (95% CI: 0.23–0.80) weeks of TTD and an extra $1,248 (95% CI: $810–$1,686) in monetary compensation. Discharge to an intermediate care facility following the initial hospitalization was associated with an increase of 8.15 (95% CI: 4.03–12.28) weeks of TTD and an increase of $23,440 (95% CI: $17,033–$29,847) in monetary compensation.ConclusionsWe were able to link data from the initial hospitalization for an injured worker with the final workers' compensation claims decision or settlement. The in‐hospital measures of injury severity were associated with total monetary compensation as captured in the workers' compensation process. Am. J. Ind.

Published: June 2013

BackgroundPatients with nonallergic irritant rhinitis (NAIR) have symptoms of nasal congestion, nasal irritation, rhinorrhea, and sneezing in response to nasal irritants. We currently have no reliable objective means to quantify these patients’ subjective symptoms. In this study, we used the transient receptor potential vanilloid receptor (TRPV1) receptor agonist, capsaicin, as an intranasal challenge while comparing the changes in blood flow with optical rhinometry between subjects with NAIR and healthy controls (HCs).MethodsSix HCs and 6 NAIR subjects were challenged intranasally with saline solution followed by increasing concentrations of capsaicin (0.005 mM, 0.05 mM, and 0.5 mM) at 15‐minute intervals. We recorded maximum optical density (OD) and numeric analog scores (NAS) for nasal congestion, nasal irritation, rhinorrhea, and sneezing for each subject after each challenge. Correlations between NAS and maximum OD were calculated.ResultsMaximum OD increased with increasing concentrations of intranasal capsaicin in NAIR subjects. There were significant differences in maximum OD obtained for 0.05 mM and 0.5 mM capsaicin between NAIR subjects and HCs. Significant differences were found in the NAS for nasal irritation at 0.005 mM, 0.05 mM, and 0.5 mM, and nasal congestion at 0.5 mM. Correlation between maximum OD and mean NAS was most significant for 0.05 mM capsaicin.ConclusionOptical rhinometry with intranasal capsaicin challenge could prove a viable option in the diagnosis of NAIR. Further studies will investigate its use to monitor a patient's response to pharmacologic therapy and provide further information about the underlying mechanisms of NAIR.
Acetazolamide for high intracranial pressure cerebrospinal fluid leaks
Authors: Chaaban Mohamad R. , Illing Elisa , Riley Kristen O. , Woodworth Bradford A. 
Published: June 2013

BackgroundAcetazolamide has become a standard treatment for cerebrospinal fluid (CSF) leaks associated with intracranial hypertension. The purpose of the current study was to evaluate the effectiveness of acetazolamide at decreasing elevated CSF pressure in this patient population.MethodsProspective evaluation and data collection of high intracranial pressure CSF leaks was performed. Subjects underwent CSF diversion and postoperative assessment of pressure changes via a standard protocol. Lumbar drains or ventriculostomies were clamped on postoperative day 2 for 4 hours prior to assessment with a manometer. Acetazolamide (500 mg) was administered orally immediately following the recording and CSF pressure was measured after 4 hours. Data regarding demographics, etiology of CSF leak, body mass index (BMI), location and size of defect, and clinical follow‐up were also collected.ResultsThirty‐six patients (average age 50 years) with 42 CSF leaks (39 spontaneous, 3 traumatic) and an average BMI of 36.1 were evaluated. Success rate of primary repair was 94.4%, but all patients were effectively sealed with subsequent endoscopic reconstruction (average 80 weeks follow‐up). Intracranial pressure (cm H2O) via lumbar puncture or ventriculostomy (n = 2) after clamping was 32.0 ± 7.4. Administration of acetazolamide significantly decreased intracranial pressure to 21.9 ± 7.5 in the 4–6 hour time frame studied (p < 0.0001).ConclusionThis study provides some of the first direct evidence of decreased intracranial pressure associated with the oral administration of acetazolamide. In combination with the excellent endoscopic repair outcomes noted in a high risk population, this evidence supports the routine use of acetazolamide in patients with high intracranial pressure CSF leaks.
Porous and spherical hydroxyapatite microcomposites for immunoglobulin G adsorption
Authors: Akkaya Birnur 
Published: June 2013

ABSTRACTA novel porous and spherical hydroxyapatite (HA) microcomposite with an average diameter of 50–100 μm was produced by suspension polymerization for the adsorption of human immunoglobulin G (IgG). The specific surface area of the pure HA and HA microcomposite were found to be 80.25 and 182.53 m2/g, respectively. Characterizations were performed with X‐ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis, and scanning electron microscopy analysis. The swelling ratio of the spherical HA microcomposites was 170%. The maximum adsorption of IgG from aqueous solution was observed at pH 7.0 (5 mM phosphate buffer) and at 45°C in a batch system in which parallel separate experiments were performed independently. An IgG adsorption capacity value of up to 140 mg/g was obtained for the HA microcomposite. The IgG molecules could be repeatedly adsorbed and desorbed through the use of spherical microcomposites without a noticeable loss in the IgG adsorption capacity. © 2013 Wiley Periodicals, Inc. J.
