Published: September 2018

Abstract. Surface pressure (Ps) and weighted mean temperature (Tm) are two necessary variables for the accurate retrieval of precipitable water vapor (PWV) from Global Navigation Satellite System (GNSS) zenith total delay (ZTD) estimates. The lack of Ps or Tm information is a concern for those GNSS sites that are not collocated with meteorological sensors. This paper investigates an alternative method of inferring accurate Ps and Tm at the GNSS station using nearby synoptic observations. Ps and Tm obtained at the nearby synoptic sites are interpolated onto the location of the GNSS station by performing both vertical and horizontal adjustments, in which the parameters involved in Ps and Tm calculation are estimated from ERA-Interim reanalysis profiles. In addition, we present a method of constructing high-quality PWV maps through vertical reduction and horizontal interpolation of the retrieved GNSS PWVs. To evaluate the performances of the Ps and Tm retrieval, and the PWV map construction, GNSS data collected from 58 stations of the Hunan GNSS network and synoptic observations from 20 nearby sites in 2015 were processed to extract the PWV so as to subsequently generate the PWV maps. The retrieved Ps and Tm and constructed PWV maps were assessed by the results derived from radiosonde and the ERA-Interim reanalysis. The results show that (1) accuracies of Ps and Tm derived by synoptic interpolation are within the range of 1.7–3.0 hPa and 2.5–3.0 K, respectively, which are much better than the GPT2w model; (2) the constructed PWV maps have good agreements with radiosonde and ERA-Interim reanalysis data with the overall accuracy being better than 3 mm; and (3) PWV maps can well reveal the moisture advection, transportation and convergence during heavy rainfall.

Abstract. The River Thames and 15 of its major tributaries have been
monitored at weekly intervals since March 2009. Monitored
determinands include major nutrient fractions, anions, cations,
metals, pH, alkalinity, and chlorophyll a and are linked to mean daily
river flows at each site. This catchment-wide biogeochemical monitoring
platform captures changes in the water quality of the Thames basin during a
period of rapid change, related to increasing pressures (due to a rapidly
growing human population, increasing water demand and climate change) and
improvements in sewage treatment processes and agricultural practices. The
platform provides the research community with a valuable data and modelling
resource for furthering our understanding of pollution sources and dynamics,
as well as interactions between water quality and aquatic ecology. Combining
Thames Initiative data with previous (non-continuous) monitoring data sets
from many common study sites, dating back to 1997, has shown that there have
been major reductions in phosphorus concentrations at most sites, occurring
at low river flow, and these are principally due to reduced loadings from
sewage treatment works (STWs). This ongoing monitoring programme will provide
the vital underpinning environmental data required to best manage this vital
drinking water resource, which is key for the sustainability of the city of
London and the wider UK economy. The Thames Initiative data set is freely
available from the Centre for Ecology and Hydrology's (CEH) Environmental
Information Data Centre at

Double Entendre, Disguised Verbal Resistance, and the Composition of Psalm 132
Authors: Schreiner David B. 
Published: September 2018

Abstract
This essay primarily discusses the composition of Ps 132, but not at the expense of its structure and literary artistry. Assuming methodological comments of A. Laato, namely, the possibility that any psalm could have existed in a precanonical form, this essay observes specific phenomena about Ps 132’s content on the way to discussing the compositional process of the psalm. This essay observes (1) that many of the data often cited as evidence for an early date of composition appear in vv. 1–12, (2) that most data in support of a late date of composition appear in vv. 13–18, and (3) there is a significant shift in the psalm’s focus beginning in v. 13. Consequently, this essay proposes that the canonical form of Ps 132 may have come about through two distinct phases, which can be characterized as a postexilic expansion of a preexilic psalm. Furthermore, the second portion of the psalm ostensibly manifests a “hidden reading” that, when understood against the hegemonic environments of the ­Second Temple period, may constitute what James Scott has characterized as “disguised ­verbal resistance.”

Este estudo tem como objetivo examinar a influência dos mecanismos de governança corporativa nos honorários de auditoria das empresas brasileiras de capital aberto pertencentes aos segmentos especiais de listagem da B3 no ano de 2016. Utilizou-se pesquisa descritiva, com procedimentos de coleta de dados documental e com abordagem de análise quantitativa. A amostra foi composta de 173 empresas brasileiras listadas na B3. Foram analisadas a relação entre o conselho de administração (tamanho, independência do conselho e dualidade do diretor), comitê de auditoria (existência, tamanho do comitê e expertise dos membros), tamanho da empresa, retorno sobre o ativo, tipo de firma de auditoria e o nível de governança corporativa com os honorários de auditoria. O banco de dados foi montado a partir do acesso à base Economática® e da coleta de formulários de referência nos sites das empresas e analisado por meio de estatística descritiva e regressão linear múltipla. Os resultados do estudo demonstram que, no âmbito do mercado de capitais brasileiro, a independência do conselho de administração, o tamanho da empresa e o tipo de firma de auditoria influenciam os honorários de auditoria. Não foram encontradas relações significativas dos honorários de auditoria com o tamanho do conselho de administração, a dualidade do diretor, a presença e o tamanho do comitê de auditoria, a expertise, o retorno sobre o ativo e o nível de governança corporativa.
Verruciform and Condyloma-like Squamous Proliferations in the Anogenital Region
Authors: Chan May P. 
Published: September 2018

Context.—Histologic distinction between condyloma acuminatum and various benign and malignant condyloma-like lesions in the anogenital area poses a common diagnostic challenge to pathologists across subspecialties.Objective.—To review the overlapping and distinguishing features of condyloma acuminatum and its mimics, and to clarify confusing terminology and diagnostic criteria for problematic entities.Data Sources.—A review of the literature on condyloma acuminatum (ordinary and giant types), verrucous carcinoma, warty/warty-basaloid high-grade squamous intraepithelial lesion and squamous cell carcinoma, papillary squamous cell carcinoma, bowenoid papulosis, verruca vulgaris, epidermolytic acanthoma, and verruciform xanthoma was performed.Conclusions.—Correct diagnosis of condyloma acuminatum and condyloma-like lesions has important clinical implication and entails familiarization with their clinical presentations and histopathologic features. Contrary to historical belief, giant condyloma acuminatum and verrucous carcinoma should be considered distinct entities based on different pathogenetic pathways. Ancillary tools available for identifying and genotyping human papillomavirus can aid in diagnosis when histopathologic findings are inconclusive. Recognition of relatively rare entities such as bowenoid papulosis, epidermolytic acanthoma, and verruciform xanthoma would avoid overdiagnosis and unnecessary, overaggressive treatment.
Le collectif comme mode d’intervention : Perturbations de La 2e Porte à Gauche
Authors: Mougeolle Marie 
Published: September 2018

La 2e Porte à Gauche invite, en 2016-2017, des artistes issus de la danse et des arts visuels à réfléchir ensemble autour de la question « Qu’est-ce que la danse peut produire (d’autre)? » L2PAG interroge alors la forme de l’oeuvre en regard du médium qui la crée, tout en interrogeant la problématique du collectif comme forme, méthode de travail et mode d’incubation d’idées ou de transgressions. Cet article tente de penser les dynamiques de création interdisciplinaires à travers le prisme de la création collective : comment faire oeuvre autrement, et à plusieurs? Comment fonder des lieuxmétis (Nouss, Plaidoyer pour un monde métis, 2005), territoires de création où identités et appartenances collaborent à faire oeuvre?
D’une interdisciplinarité-processus à une interdisciplinarité-oeuvre : La très excellente et lamentable tragédie de Roméo et Juliette de Catherine Gaudet et Jérémie Niel
Authors: Bienaise Johanna 
Published: September 2018

En 2016, le metteur en scène Jérémie Niel et la chorégraphe Catherine Gaudet présentaient leur pièce La très excellente et lamentable tragédie de Roméo et Juliette à l’Usine C (Montréal). Retraçant les propos des deux artistes tenus lors du colloque Alternatives interdisciplinaires : de l’identité des arts vivants (GRIAV, 2016), nous analysons dans cet article comment cette rencontre interdisciplinaire a pu se construire dans un dialogisme relationnel face à la question du disciplinaire, dans une interdisciplinarité-processus tout d’abord basée sur les savoir-faire de chacun en studio et dans une interdisciplinarité-oeuvre ensuite exprimée dans une production hétéromorphe soucieuse de sortir de toute catégorisation possible.
Un tragique de l’ébranlement : usages et enjeux de la catharsis dans Le sang des promesses (Littoral, Incendies, Forêts, Ciels) de Wajdi Mouawad
Authors: Jardon-Gomez François 
Published: September 2018

Consacré à la tétralogie Le sang des promesses – composée des pièces Littoral, Incendies, Forêts et Ciels – de Wajdi Mouawad, le présent article s’appuie sur un retour remarqué de la catharsis dans les discours sur le théâtre contemporain pour questionner la capacité du théâtre à développer une pensée du vivre-ensemble. J’étudie d’abord la place du tragique dans la tétralogie avant d’analyser le devenir contemporain de la catharsis, son articulation autour des émotions de peur et de compassion et l’importance de la parole-action au sein de l’oeuvre. Enfin, je redéfinis les rapports entre le cathartique et la « solidarité des ébranlés » théorisée par Jan Patočka avant d’analyser la réception critique des pièces pour y trouver des exemples concrets de l’effet cathartique propre au théâtre de Mouawad.
Gestion intégrée du roseau commun à la réserve naturelle du Marais-Léon-Provancher (Neuville, Québec)
Authors: Messier François , Courtois Réhaume 
Published: September 2018

Le roseau commun exotique (Phragmites australis [Cav.] Trin. ex Steud. subsp. australis) s’est propagé graduellement au cours des 20 dernières années dans la réserve naturelle du Marais-Léon-Provancher, un site de 125 ha avec 19 ha de marais d’eau douce. Des inventaires réalisés de 2013 à 2015 ont permis d’identifier 41 clones de roseau sur le territoire du marais. Compte tenu des conditions du milieu et de l’accessibilité au site, 5 méthodes ont été privilégiées pour lutter contre le roseau : l’arrachage manuel des rhizomes, la fauche des tiges, le bâchage, l’excavation mécanique avec ensemencement et l’implantation d’une compétition végétale. La superficie totale occupée par les clones de roseau à la suite des interventions a diminué de 19 %, passant de 7579 m2 en 2013 à 6132 m2 en 2017. L’excavation mécanique avec ensemencement, l’arrachage manuel et le bâchage ont engendré de fortes diminutions des superficies occupées par le roseau (baisses respectives de 99 %, 88 % et 47 %), tandis que la fauche et la compétition végétale ont eu un effet plus faible (diminution d’au plus 28 %).
Reconstitution historique de l’invasion du Québec par le myriophylle à épis (Myriophyllum spicatum)
Authors: Jacob-Racine Romy , Lavoie Claude 
Published: September 2018

Le myriophylle à épis (Myriophyllum spicatum) est une plante vasculaire exotique envahissante qui colonise les lacs et les rivières de l’Amérique du Nord depuis plusieurs décennies. Nous avons reconstitué la progression historique de son invasion au Québec à l’aide de spécimens d’herbier, de bases de données, de rapports, de journaux et de périodiques. L’aire de répartition de la plante s’est beaucoup étendue depuis son introduction à la fin des années 1950. L’espèce s’est d’abord disséminée le long du fleuve Saint-Laurent. Elle s’est ensuite propagée à l’intérieur des terres à partir des années 1970. En 2017, 14 des 17 régions administratives du Québec comptaient au moins une mention de myriophylle à épis. Cela représentait 132 lacs, 16 rivières et ruisseaux — y compris le fleuve Saint-Laurent et ses lacs fluviaux — et 4 autres plans d’eau, tels que des étangs ou des voies navigables artificielles. À lui seul, le fleuve Saint-Laurent représentait 24 % des 322 mentions. Les régions avec le plus grand nombre de mentions sont celles de la Montérégie, des Laurentides, de l’Estrie et de l’Outaouais. Bien que l’envahissement par le myriophylle à épis semble avoir progressé de manière importante ces dernières années, il est possible que l’augmentation du nombre d’observations soit davantage le reflet d’une préoccupation grandissante des acteurs du territoire par rapport à l’envahisseur que d’une accélération réelle de l’invasion.
Caractérisation et protection de l’habitat du poisson dans la rivière Beaudette (Québec)
Authors: Sinave Emily , Grégoire Taillefer Amélie 
Published: September 2018

La rivière Beaudette est un lieu de fraie pour diverses espèces de poissons et un sanctuaire de pêche important pour la région de Vaudreuil-Soulanges. Toutefois, elle subit diverses dégradations à la suite du lessivage de sédiments provenant des activités agricoles environnantes et de la dénaturalisation des berges en milieu résidentiel. Le but de cette étude était d’acquérir des connaissances sur le bassin versant de la rivière Beaudette (Québec) afin de documenter les menaces affectant le potentiel de l’habitat du poisson. Ceci s’est fait en caractérisant l’habitat, en évaluant la qualité des bandes riveraines, en analysant la qualité de l’eau, en recensant les marques d’érosion des rives et par des inventaires ichtyologiques. Les analyses de la qualité de l’habitat du poisson indiquent que près de 75 % de la rivière obtient une cote variant de « faible » à « très faible ». De plus, la rivière obtient généralement un indice « faible » en ce qui concerne sa capacité à accomplir ses fonctions écologiques. L’inventaire ichtyologique démontre que la rivière Beaudette comprend une richesse spécifique qui est plus grande en présence de bandes riveraines de bonne qualité ainsi qu’à des valeurs élevées de l’indice de qualité de l’habitat du poisson. Ces résultats confirment le besoin d’intervenir pour assurer la pérennité des écosystèmes de la rivière Beaudette.
Position Measurement over Wide Range by Simultaneous Use of Low and High Coherence Light Source
Authors: Tomić Miloš C. , Đinović Zoran V. 
Published: September 2018

In this paper we propose and experimentally demonstrate a new technique for position/displacement measurement using fiber optic interferometry. We simultaneously employ a low- and a high- coherence light source in the same opto-mechanical configuration. The low coherence signal was obtained using a Fizeau receiving interferometer, implemented as an optical glass wedge, accompanied by a linear CCD array. Combining low- and high-coherence parts was possible because we showed that the accuracy of low-coherence based position measurement was better than 50 nm, less than the high coherence signal periodicity. We verify the method in the dynamic range of low-coherence measurement of about 100 m, while the accuracy of the high-coherence part was about ±1 nm. Thus, the method provides more than 100,000 measuring points. The advantages of this sensing technique include absolute position/displacement measurement in a large dynamic range with nanometer accuracy.
Some examples of photorefractive oscillators
Authors: Ljuboje Zoran 
Published: September 2018

The photorefractive effect presents a periodical change of the refractive index of an optical environment under the influence of a coherent light. An interesting phenomenon which occurs at this effect is optical phase conjugation (PC). Photorefractive oscillators, that is photorefractive mirrors present important decides in photorefractive optics and their function is based on photorefractive effect. In these oscillators, a phase-conjugated light beam occurs. The basic characteristics of photorefractive oscillators, such as reflectivity, the existance of the oscillation threshold and the threshold of the coupling strength are explained by the so-called grating-action method. This is analysed on a ring oscillator, semilinear mirror and linear mirror.

The proposed filter is based on VDTAs, capacitors and resistors. The functionality of the circuit is verified using PSPICE with TSMC CMOS 0.18μm process parameters for test signals of 50, 150, 250, and 350 Hz.
Evaluation Method for Green Ecological Airports in China Based on Combination Weighting
Authors: Bao Danwen , Zhang Xiaoling , Gu Jiayu 
Published: September 2018

To scientifically and accurately evaluate the status of the development of green airports in China, evaluation methods of green, ecological airports are established in this paper. To address the shortcomings in subjective and objective weighting methods, we propose a combination weighting method based on Spearman’s rank correlation coefficient and evaluation grades based on interval approximation. At the same time, by taking into account resource conservation, environmental friendliness, operation efficiency, and people-oriented service, we propose an evaluation index system and an interval number for each index. Lastly, the theory is applied to five large airports in different regions of China. Analysis of the evaluation results shows that Shanghai Pudong International Airport (PVG) and Guangzhou Baiyun International Airport (CAN) have the highest scores for the resource conservation and environmental friendliness indexes, thus indicating that the development of a green ecological airport is closely related to its passenger transportation scale and economic strength. All considered airports showed the need for upgrading public service facilities and constructing intelligent equipment. The method proposed in this paper is reasonable and reliable; therefore, it can provide guidance for the evaluation and construction of green, ecological airports.
A Hybrid Short-term Traffic Flow Forecasting Method Based on Neural Networks Combined with K-Nearest Neighbor

Published: September 2018

It is critical to implement accurate short-term traffic forecasting in traffic management and control applications. This paper proposes a hybrid forecasting method based on neural networks combined with the K-nearest neighbor (K-NN) method for short-term traffic flow forecasting. The procedure of training a neural network model using existing traffic input-output data, i.e., training data, is indispensable for fine-tuning the prediction model. Based on this point, the K-NN method was employed to reconstruct the training data for neural network models while considering the similarity of traffic flow patterns. This was done through collecting the specific state vectors that were closest to the current state vectors from the historical database to enhance the relationship between the inputs and outputs for the neural network models. In this study, we selected four different neural network models, i.e., back-propagation (BP) neural network, radial basis function (RBF) neural network, generalized regression (GR) neural network, and Elman neural network, all of which have been widely applied for short-term traffic forecasting. Using real world traffic data, the experimental results primarily show that the BP and GR neural networks combined with the K-NN method have better prediction performance, and both are sensitive to the size of the training data. Secondly, the forecast accuracies of the RBF and Elman neural networks combined with the K-NN method both remain fairly stable with the increasing size of the training data. In summary, the proposed hybrid forecasting approach outperforms the conventional forecasting models, facilitating the implementation of short-term traffic forecasting in traffic management and control applications.
Estimation of Aerodynamic Coefficients in a Small Subsonic Wind Tunnel
Authors: Krajček Nikolić Karolina , Domitrović Anita , Janković Slobodan 
Published: September 2018

To apply the experimental data measured in a wind tunnel for a scaled aircraft to a free-flying model, conditions of dynamical similarity must be met or scaling procedures introduced. The scaling methods should correct the wind tunnel data regarding model support, wall interference, and lower Reynolds number. To include the necessary corrections, the current scaling techniques use computational fluid dynamics (CFD) in combination with measurements in cryogenic wind tunnels. There are a few methods that enable preliminary calculations of typical corrections considering specific measurement conditions and volume limitation of test section. The purpose of this paper is to present one possible approach to estimating corrections due to sting interference and difference in Reynolds number between the real airplane in cruise regime and its 1:100 model in the small wind tunnel AT-1. The analysis gives results for correction of axial and normal force coefficients. The results of this analysis indicate that the Reynolds number effects and the problem of installation of internal force balance are quite large. Therefore, the wind tunnel AT-1 has limited usage for aerodynamic coefficient determination of transport airplanes, like Dash 8 Q400 analyzed in this paper.
