Authors: Andrade Salazar Jose Alonso , Estrada Sánchez Catherine , Penagos Marín Andrés Camilo 
Published: March 2018

Objetivo: Comprender las representaciones sociales del VIH a través de las percepciones, creencias y actitudes de adolescentes escolarizados en los grados 9°, 10° y 11° de bachillerato. Materiales y métodos: Se aplicó a los participantes una entrevista semi-estructurada, teniendo en cuenta los criterios de objetivación y anclaje, para identificar el proceso de formación de las representaciones sociales, y las dimensiones de información, campo de representación y actitudes, tomando como base teórica lo planteado por Serge Moscovici y Jodelet, y los aportes de Mora al estudio de las representaciones sociales. Resultados: Percepción de deterioro progresivo (físico, social y familiar), rechazo, discriminación y estigmatización; creencias de diminución de calidad de vida, muerte rápida, mayor en quienes tienen relaciones sexuales de riesgo; actitudes de rechazo hacia los portadores y personas promiscuas. Las representaciones sociales del riesgo de contraer VIH se organizan en torno a conceptos poco fundamentados acerca de la enfermedad, prejuicios relacionados con el rechazo, y la evitación del contacto, e ideas erradas acerca del contagio. Conclusiones: La objetivación está relacionada con el contexto social y educativo, así la representación se ve mediada por el conocimiento especializado y sentido común. En el anclaje prevalece la actitud de rechazo ante la transmisión, lo cual restringe la familiarización con la enfermedad, limita el contacto y la aceptación gradual de la persona contagiada. Las creencias-erróneas sobre formas de contagio, producen actitudes de rechazo, porque a los adolescentes se les dificulta hacer habitual lo extraño (anclaje).

Structural Anomalies in Stirred Submerged Bioreactors Relevant to Immersed Membrane Use

Published: March 2018

Separation of value-added food additives is often practiced by micro and ultrafiltration membranes in integrated submerged membrane bioreactors (sMBR) and the flow conditions are of major importance for their performance. The immersed membranes affect fluid circulation and may cause operational difficulties. Such malfunction termed flow structural deterioration of integrated vessels is addressed in this study, based on the effect of the (1) non-Newtonian component presence, and the (2) gas flow rate. Ranges of input parameters referring to power law non-Newtonian fluids with consistency coefficients of 0.02 to 0.1Pa.sn (flow index n<1) and gas flow rate 1 - 2vvm are studied. Computational fluid dynamics (CFD) simulation of a dual impeller bioreactor equipped with a mono-tubular membrane module and alternatively flat-blade or curved-blade impellers was carried out. 3-D “k-ε” turbulent flow model is used and 2-D contour plots are worked out to illustrate cases of restricted fluid mobility in the vicinity of membrane walls. The corresponding performance parameters, gas volume fraction and fluid surface velocity are discussed. Flow structural anomalies referring to zones at the immersed membranes of extremely low membrane surface velocity (<1mm.s-1) and velocity gradients (<10s-1) that are risky for membrane fouling are uncovered.Practical applications. Fermentation of food ingredients in stirred vessels combined with recovery of the value-added product is the target application. Examples are the production and recovery of peptides, gums’ (gelatin, pectin) concentration, production of fructoolligosaccharides, galactoglucomannan, enzymatic hydrolysis combined with selective ultrafiltration in processing of vegetable proteins, production of antioxidants. Viscous dispersions of food ingredients such as starch or xanthan and operating variables - impeller speed, rate of gassing - at various level may cause undesirable effects in the bioreactor flow uniformity leading to decrease of membrane separation efficiency. The cases engaging process fluids of high consistency such as exopolysaccharide dispersions are specific in this category. Restricted fluid mobility in the vicinity of the membrane module reduces the rate of fusion across the membrane surface and blocks up the product recovery. The resulting membrane fouling and the flow structural anomalies adhere to the problem of fouling control and to submerged membrane bioreactor applications

Published: March 2018

Following our previous studies on the catalytic activity of electrochemically deposited on glassy carbon Rh electrocatalyst towards the reduction of hydrogen peroxide (H2O2), the electrochemical behaviour of the modified electrode was studied by means of cyclic voltammetry and chronoamperometry at pH-values from 5.0 to 9.0. The modified electrode exhibited a rapid, sensitive and reproducible response for the quantitative determination of H2O2 at low applied potential. Amperometry carried out at constant potential of 0 V (vs. Ag/AgCl, 3M KCl) at pH 6.0 (25 oC) gave the following operational parameters: detection limit of 4 μM, linear dynamic range 0.01 – 5.5 mM and electrode sensitivity of 377 μA mM−1 cm−2 .
The Bacton Altar Cloth: Elizabeth I's ‘long-lost skirt’?
Authors: Lynn Eleri 
Published: March 2018

Blanche Parry was Chief Gentlewoman and close confidante of Queen Elizabeth I. She was an influential courtier and received regular gifts of clothing from the queen, as a sign of favour and friendship. Blanche was a native of the small village of Bacton, Herefordshire, and, though it was a world away from the courts that she knew for most of her life, she evidently retained a deep affection for the place of her birth. She commissioned an elaborate monument within the church of St Faith, Bacton, and made generous bequests to the parish. Further connections between the late Tudor court and the small village can be seen in the form of a distinctly late sixteenth-century embroidered altar cloth that belongs to the church. The altar cloth was traditionally associated with Blanche, and it has been assumed over the years that it was a direct gift or bequest from Blanche herself. However, recent research conducted by the author and conservators at Historic Royal Palaces supports the more intriguing proposition that the altar cloth was, in fact, fashioned from a high-status court dress that may have once been the forepart of one of Queen Elizabeth I's own skirts. This article aims to prove this proposition through an analysis of materials and techniques, and of the evidence that links Bacton with the royal court itself.

Objective: This article seeks to present a pilot project of community intervention that aims to prevent the occurrence of falls in the elderly in a community setting.
Method: It is a prospective study in the temporal relationship, based on Health Planning, it was developed for 9 weeks in a Community Care Unit in the Northern Region of Portugal. Data collection and interventions were performed in the home of 6 of the 12 elderly being followed up at home by the nursing team. Elderly institutionalized and totally dependent were excluded. For the collection of data, an evaluation protocol was filled out using the Morse scale, validated for the Portuguese population, to assess the risk of falls.
Results: Of the elderly who underwent nursing interventions, 50% presented a high risk of falls. Epidemiological indicators show that the incidence rate of falls was 0% and the prevalence rate of falls, in the last year was, 37.5%.
Conclusion: The data collected was used for the production of epidemiological indicators, structure, process, and results. It is suggested to continue the project for one year, covering a larger sample and subsequent evaluation, and the creation of indicators for informal care providers.
EUCLIA—Exploring the UV/Optical Continuum Lag in Active Galactic Nuclei. I. A Model without Light Echoing

Published: March 2018

Abstract
The tight interband correlation and the lag–wavelength relation among UV/optical continua of active galactic nuclei have been firmly established. They are usually understood within the widespread reprocessing scenario; however, the implied interband lags are generally too small. Furthermore, it is challenged by new evidence, such as that the X-ray reprocessing yields too much high-frequency UV/optical variation and that it fails to reproduce the observed timescale-dependent color variations among the Swift light curves of NGC 5548. In a different manner, we demonstrate that an upgraded inhomogeneous accretion disk model, whose local independent temperature fluctuations are subject to a speculated common large-scale temperature fluctuation, can intrinsically generate the tight interband correlation and lag across the UV/optical and be in nice agreement with several observational properties of NGC 5548, including the timescale-dependent color variation. The emergent lag is a result of the differential regression capability of local temperature fluctuations when responding to the large-scale fluctuation. An average speed of propagations as large as ≳15% of the speed of light may be required by this common fluctuation. Several potential physical mechanisms for such propagations are discussed. Our interesting phenomenological scenario may shed new light on comprehending the UV/optical continuum variations of active galactic nuclei.
Corporéité et possession diaboliques dans le roman de Robert le Diable
Authors: Roger Claire 
Published: March 2018

Figure incontournable du paysage normand, Robert le Diable a suscité bon nombre d’études. Les origines diaboliques du personnage jouent un rôle majeur dans la construction de la légende et offrent une vision du diable et du possédé en ce début du xiii e siècle. Toutefois, relire cette légende normande au regard de l’histoire des représentations et des normes notamment théologiques permet d’éclairer la nature plus complexe de Robert le diable, ainsi qu’une meilleure compréhension de ce personnage entre incarnation et possession diabolique.
La statue du Juif errant de Victor-Edmond Leharivel-Durocher à Flers (Orne), 1877-1941
Authors: Huet-Pouthas Viviane 
Published: March 2018

Le mythe du Juif errant a donné lieu à des représentations imagées très populaires. Pourtant, on connaît peu de statues le figurant. Celle de Flers est l’œuvre du sculpteur normand Leharivel-Durocher, auteur de nombreuses œuvres religieuses. « Son » Juif errant est inspiré de l’iconographie chrétienne du Moyen Âge et de l’imagerie d’Épinal. Leharivel-Durocher expose le plâtre au salon de 1877, puis en réalise le bronze commandé pour Flers par le directeur des Beaux-Arts. La statue est placée en 1881 au square Delaunay. Sa « vie » n’y est pas de tout repos. De nombreux outrages lui sont infligés et elle fait l’objet de poèmes antisémites. Mais, en même temps sont publiés des articles de presse qui prennent sa défense et des poèmes qui montrent une certaine compassion à son égard. En 1922, elle est déplacée au jardin public pour laisser place au monument aux Morts. Elle y restera jusqu’à son départ pour la fonte en 1941. On garde son souvenir au travers des cartes postales éditées au début du xx e siècle, envoyées par des visiteurs de Flers à leur famille ou amis.
Malikai Project - Design of TLP Foundation Pile at Geologically Challenging Area, Offshore Malaysia
Authors: Ng Yong-Chen , Hadley C. , Suroor H. 
Published: March 2018

Abstract
Malikai development project features Malaysia's first tension leg platform (TLP) installation. The TLP tendon piles were designed by leveraging practice and experience from the Gulf of Mexico whilst taking site-specific earthquake design criteria into consideration. A comprehensive site investigation was performed for site characterization, geohazard assessment, and development of data for facilities design.
The TLP is tethered to the seafloor with eight tendons, each of which is connected to a 2.44 m diameter by 130 m long, 425 tonne foundation pile. Pre-service load cases, including transportation/handling and stability at self-penetration free-standing condition, plus in-place load cases, including hull and tendon damage cases, and earthquake condition, were considered in the design. An extensive seismic design analysis was carried out involving site response analysis to determine the kinematic effect as well as inertia loading on pile design as per ISO 19901-2 based on site specific seismic design criteria.
The TLP foundation piles were installed in May through June, 2016. Actual piling performance observed in the field matched model predictions. The recorded self-weight penetration of all eight piles was within the predicted range. The piles were driven using an underwater hydraulic hammer to a target penetration depth of 124 m and the measured blow-count agreed with "best-estimate" predictions of drivability.
This paper presents the overall design process, including site investigation, the selection of TLP site to avoid geohazards, detailed geotechnical and structural design of piles. Pile installation records and field observations are also presented and compared to pre-installation predictions.
The Impact of Ion Exchange and Surfactant Partitioning on ASP Modeling, A Brown Offshore Field
Authors: Ghadami Nader , Tewari Raj Deo , Zarubinska Maria , Motaei Eghbal 
Published: March 2018

Abstract
In order to design and analyse Alkaline Surfactant Polymer (ASP) pilots and generate reliable field forecasts, a robust scalable modeling workflow for the ASP process is required. Accurate modeling of an ASP flood requires detailed representation of the geochemistry and the saponification process, if natural acids are present. The objective of this study is to extend the existing models of ion exchange and surfactant partitioning between phases to improve the quality of the model.
Geochemistry and saponification affect the propagation of the injected chemicals. This in turn determine the chemical phase behaviour and hence the effectiveness of the ASP process. A starting point of such a workflow is to carry out ASP coreflood tests and history matching (HM) using numerical models. This allows validation of the models and generates a set of chemical flood parameters that can be used for forecasts. The next step is upscaling from lab to field. The presence of (geo)-chemistry in ASP model improves significantly the quality of core HM especially for produced chemicals, breakthrough time and their profiles shape.
The addition of surfactant partitioning between the oleic and the aqueous phases based on salinity of the system as well as propagated distance (time) improves understanding of the required surfactant concentration. The partitioning of surfactant is important for coreflood matching of native cores as they tend to have more clays and minerals that affect ASP phase behaviour. The upscaling of the HM coreflood was conducted in two steps. First step the coreflood was scaled up with the distance between injector–producer pair as the scaling parameter. Second step was the application of the scaled up injection rates, residual saturations, etc. to the full field model. Sensitivity study for parameters such as grid size, well distance, ASP slug size, and rate of surfactant partitioning was performed. It was found that grid size of 50ft was optimum for ASP modeling. The higher rate of surfactant partitioning resulted to lower recovery. The optimal well distance was determined as 700ft for optimization of oil recovery. The reduction of ASP slug size from 0.5PV to 0.3PV leads to the reduction in oil recovery by 2-3%.
Usually chemical reactions accompanied ASP process are left out of the model due to increase in complexity as well as longer computational time. However, their addition as well as presence of surfactant partitioning between the oleic and the aqueous phases makes ASP models more realistic and it results in significant improvement to coreflood HM quality and prediction of ASP process.
Application of Artificial Intelligence Methods for Predicting Water Saturation from New Seismic Attributes.

Published: March 2018

Abstract
Accurate determination of water saturation is fundamental for predicting the amount of hydrocarbon fluid in reservoir, apart from monitoring fluid saturation changes whithin the reservoir using 4D seismic technology in the most efficient manner. In fact, although several techniques can be employed to predict water saturation, the well log based approaches have emerged as the most widely applied methods. Nevertheless, even though these techniques offer rather exceptional vertical resolution, it is a fact that lateral estimation is still an issue.
As such, this study proposes a methodology that estimates the water saturation based on pre-stack seismic information by using artificial intelligence (AI) technologies, such as artificial neural network (ANN), adaptive neuro-fuzzy inference systems optimized by genetic algorithm (ANFIS-GA), as well as support vector machine (SVM). Therefore, the seismic data would go through a process known as seismic inversion and then transformed into seismic attributes, represented as SQp and SQs, this transformation is adherent to attenuation concept, which is associated to the rock physics.
On top of that, data from two wells in Malaysian hydrocarbon field were employed to build the estimation models of ANN, ANFIS-GA, and SVM and then third well data was used as blind well to test unseen data. Furthermore, both SQp and SQs had been employed in the models as input variables, whereas the water saturation functioned as output. Other than that, several performance indices of statistical had been incorporated in this study so as to perform a comparison between the performances exerted by the selected models. As a result, the findings indicated thatalthough all models showed an acceptable agrrement with the experimental data to some extent, the ANFIS-GA based model had a better performance over other models.
The present study show that the AI technology can be incorporated in water saturation prediction workflow from pre-statck seismic data which result in superior accuracy and performance in fluid flow calculations and time lapse seismic analysis.
