Published: February 2017

IN Concluding the Editor's Foreword to the 1950 Edition of D. O. Fagunwa's First Novel, the Classic Ogboju Ode Ninu Igbo Irunmale, L. Murby spoke generally of the three novels the Yoruba author had published by then:[I]n their treatment of character and story, in their use of myth and legend and allegory, and in their proverbial and epigrammatic language [the novels] bear definite resemblances to the Odyssey and Beowulf and the early medieval romances on the one hand, and on the other hand to that great cornerstone of the English novel, Bunyan's The Pilgrim's Progress.
Validación de contenido de una versión culturalmente adaptada al contexto venezolano de la Escala de Perfeccionismo Infantil de Oros

Published: February 2017

Introducción: a pesar de su importancia, el reporte formal y pormenorizado de la validez de contenido de los instrumentos psicométricos ha sido frecuentemente descuidado. En un trabajo previo, la Escala de Perfeccionismo Infantil de Oros (2003), de origen argentino, fue adaptada lingüística y culturalmente al contexto venezolano. Objetivo: el propósito del presente estudio fue estimar la validez relacionada con el contenido de la versión venezolana de la escala antedicha a través del criterio de jueces. Metodología: un grupo de expertos en el tema del perfeccionismo juzgó si existe correspondencia entre lo que parece que mide cada reactivo del instrumento y la dimensión a la que pertenece; para cuantificar el acuerdo interjueces se usó el denominado Índice de Validez Factorial (fvi). Resultados: la escala total ylas llamadas “Autodemandas”, que se refieren a pensamientos perfeccionistas, obtuvieron índices satisfactorios (fvi > 0,80). Hubo menos acuerdo con los ítems de la dimensión “Reacciones ante el fracaso”, en parte atribuible a factores de diferenciación cultural que influyen en la expresión emocional. Conclusiones: ahora puede proseguirse con el resto de la validación psicométrica de la prueba. Otros estudios que persigan un objetivo similar al de este trabajo podrían emular el procedimiento aquí expuesto.

Introducción: los datos que se registran sobre el consumo de alcohol son importantes para el diagnóstico y pronóstico de trastornos por uso de alcohol. Objetivo: este estudio descriptivo tuvo como objetivo caracterizar las referencias sobre consumo de alcohol y otras variables relacionadas en los registros hospitalarios de pacientes atendidos en una unidad especializada en alcoholismo de un hospital público de la ciudad de Mar del Plata, Argentina. Metodología: se examinaron los registros de 60 admisiones entre febrero y noviembre del 2011, y se categorizaron extrayendo datos referidos al consumo de alcohol, fuente de la derivación, diagnóstico, tratamiento, internaciones y otras enfermedades, así como aspectos del entorno familiar y socioeconómico. Posteriormente, se realizaron análisis descriptivos teniendo en cuenta el porcentaje de registros en los que se mencionaban estos aspectos. Resultados: si bien el registro de datos referentes al consumo de alcohol fue alto, por lo general fue incompleto. La información registrada denotó que las condiciones biopsicosociales en las que se encuentran estos pacientes son poco favorables para un tratamiento exitoso. Conclusiones: se discute la necesidad de sistematizar la información, por ejemplo, a través de historias clínicas unificadas, junto con formas de prevenir la progresión de trastornos por uso de alcohol.

Similar Biologics: Global Opportunities and Issues
Authors: Ghosh Prasanta Kumar 
Published: February 2017

The invention and use of a large number of biologics during the last three decades for treating various deficiencies and chronic disorders has resulted in great benefit to human health. Abundant use of these biologics has been considerably constrained due to the reasons of their increased prices, charged by the inventors up to the time up to which their use were/are protected by intellectual property rights (IPR).Some of these biologics are presently being manufactured by the existing and newer companies as “similar biologics” after the IPR on these products have expired and as a result the prices of several such medicines are coming down.“Similar biologics” are also referred to as “biosimilars” and other related names in different parts of the world. The regulatory authorities of different countries have authorized use of “similar biologics” based on comparative evaluation of each of such medicines with the inventor’s biologics; these are approved when considered to be closely similar to the inventor’s biologics in properties, quality and efficacy. By 2020, a dozen of “inventor’s biologicals” having estimated market sale-value of over USD 79 billion are going out of protection of IPR. This would drive entrepreneurs to enter in to the field and the prices are going to crash considerably due to market competition. In course of time more “biosimilars” would go out of IPR. Different proactive governments and the regulatory agencies all over the world are trying to harness the existing and future opportunities by creating regulatory guidelines to ease faster authorization for use of “similar biologics” in their territories. Up to the present time, a small number of “similar biologics” have been approved for use in different countries all over the major parts of the world. More efficient technologies for manufacture of “similar biologics” are also getting developed. Together, these efforts are anticipated to ease the availability of “similar biologics” at more affordable prices to the users/ payers the world over. This article is open to POST-PUBLICATION REVIEW.

Published: February 2017

As universidades possuem em seu cerne as atividades de ensino, pesquisa e extensão que, indissociáveis, devem primar pela boa formação do futuro profissional e pela produção e divulgação de saberes científicos. No âmbito da extensão, os projetos devem atender não apenas aos interesses da comunidade, mas também às competências necessárias ao graduando monitor/estagiário. Pautado na análise bibliográfica e em entrevistas semi-estruturadas realizadas com oito monitores/estagiários do projeto “GYMNUSP: Escola de Ginástica”, - por sua vez, analisadas pela análise de conteúdo - este artigo versa sobre as percepções oriundas da experiência em um projeto de extensão em ginástica pautado nos princípios da ginástica para todos. Os resultados explicitaram que, para além dos benefícios financeiros e relacionados ao cumprimento de estágios, os monitores/estagiários consideraram o projeto de extensão importante para o contato com a prática profissional e com o público de atuação (no caso, infanto-juvenil), para a ampliação de campos de prática (ginástica), para melhor compreensão da organização de aulas e da atuação didática e para inserção no ambiente esportivo, por meio da participação em festivais.

Published: February 2017

Nowadays, people do not need to go to the library for searching knowledge or information. World has changed. We come to the new generation that so called as digital native generation. Information can be searched through the gadgets on hands which is connected to the internet. Then question comes, is the library still important? What should the library do? It is no wonder that most of the libraries have been decreasing its number of visitors as well as its number of books that out of the shells. This paper describes the characteristics of the digital native, people habit in learning and reading books. It also summarizes some discussions among the heads of the three university libraries in Surabaya, i.e, Intitut Teknologi Sepuluh (ITS) Nopember Surabaya, Petra Christian University (PCU), Surabaya Universities (Ubaya). The results of the discussion show that library has to be changed so that they can accommodate the needs of the digital native. It is not only the place for borrowing books, but also the place for doing discussion, watching videos and listening to audios, and of course the online materials must be provided to encounter the decreasing visitors.

Gas Effect in Electrical-Submersible-Pump-System Stage-by-Stage Analysis
Authors: Oliva G. B. , Galvão H. L. , dos Santos D. P. , Silva R. E. , Maitelli A. L. , Costa R. O. , Maitelli C. W. 
Published: February 2017

Summary
One of the main problems regarding the use of the artificial-lift method of electrical-submersible-pump (ESP) systems is the presence of gas in the pump. This paper presents and describes an analysis of ESP systems with a stage-by-stage calculation to determine intake and discharge pressures to adjust total dynamic head (TDH) for each stage of the pump.
The modeling was designed to acknowledge free gas in the pump, and iterative calculations are applied to recalculate, for each stage, fluid characteristics and physical properties, such as viscosity, density, formation volume factor (FVF), surface tension, solubility ratio, gas/oil ratio (GOR), and other flow characteristics along the tubing, such as temperature and pressure. Developed modeling validation was achieved by comparisons in two scenarios. In the first one, fixed values of intake pressure and changeable values of GOR were used to assess gas effect. In the tests for the second scenario, fixed values of GOR and changeable values of intake pressure were used.
Necessary research was conducted through a developed computational tool used to size ESP components. The results were different from those obtained with the usual calculations, and it may be implied that the developed modeling is more accurate to determine parameters related to this artificial-lift method. Also, the results were more consistent and closer to the actual behavior of multiphase-flow phenomena within the tubing because each stage has its characteristics individually evaluated. These observations may have an effect on the number of pump stages and influence in choosing the adequate equipment of the system.
Computational Fluid Dynamics Applied To Investigate Development of Highly Conductive Channels Within the Fracture Geometry
Authors: Gomaa Ahmed M. , Hudson Harold , Nelson Scott , Brannon Harold 
Published: February 2017

Summary
A conventional proppant pack may lose up to 99% of its conductivity because of gel damage, fines migration, multiphase flow, and non-Darcy flow. Therefore, the concept of pillar fracturing was developed to generate highly conductive paths for hydrocarbon to flow. This paper describes experimental results and numerical models of a new method to generate stable proppant pillars. The proposed treatment method depends on fingering phenomena observed when a less-viscous fluid that does not carry proppant is injected to displace a more-viscous one that carries proppant. Because the low-viscosity fluid tends to move faster than the high-viscosity fluid, the low-viscosity fluid can penetrate the high-viscosity fluid and create channels inside it. This reshapes and divides the proppant-laden, high-viscosity fluid into isolated patterns that create proppant pillars.
Large-scale experiments (slot test, 2-ft height and 16-ft length) were performed to evaluate the development and stability of the created channels by use of different injection rates and different fluid viscosities. In addition, a computational fluid dynamics (CFD) model was constructed to simulate the experiment results and to scale them up into full fracture dimensions. The study focused on the effects of surface-injection rate [1 to 40 (bbl/min)/cluster], pulsing time (5 to 60 seconds), and viscosity ratio (from 2 to 200) between the two injected fluids.
Experimental results and numerical modeling showed that with the use of viscous-fingering phenomena, a pillar-propped fracture with conductive and stable channels can be created. Channel shape and size were dependent on injection rate where increasing the injection rate reduces the main channel width with increasing the channel branching. Full piston-displacement behavior was noticed after 60% of the fracture height, when a high-viscosity fluid displaced a low-viscosity fluid, and their viscosity ratio was greater than 5. By reducing the viscosity ratio between the two fluids, the created channel shape converts from cylindrical (where the beginning and end of the channel have the same width) to conical behavior (where the beginning of the channel is wider than the end). This explains why the length of the channel decreases with the viscosity ratio between the two fluids. Distance between pillars was reduced with increasing travel distance from the wellbore, or with reduced pulse-stage volume, time, or rate.
Nanoscale Morphology of Brine/Oil/Mineral Contacts in Connected Pores of Carbonate Reservoirs: Insights on Wettability From Cryo-BIB-SEM
Authors: Schmatz Joyce , Klaver Jop , Jiang Mingze , Urai Janos L. 
Published: February 2017

Summary
We used broad-ion-beam slope cutting in combination with scanning electron microscopy undertaken under cryogenic conditions (Cryo-BIB-SEM) to study mineral/oil/brine contacts in reservoir carbonates. This direct-imaging method allows pore-scale investigation of in-situ fluids and their distributions down to the nanometer scale.
In this study, we compare two types of carbonate reservoirs: a fine-grained Lixhe limestone (Belgium) and a coarse-grained limestone from the Maastricht area (The Netherlands). In both rock types, we first quantify the porosity with BIB-SEM and derive the spatially resolved pore connectivity of the rock from BIB-SEM on Wood's Metal (WM) injected subsamples. In the second step, subsamples were saturated with the oil analog n-hexadecane, and then flooded with NaCl brine and MgSO4 brine, respectively, to study the effect of the brine chemistry on the microscopic fluid distribution. Cryo-BIB-SEM in combination with high-resolution energy-dispersive-spectroscopy (EDS) imaging and automated image analysis on the saturated samples allowed for a quantification of the oil-droplet size, the lengths of carbonate/oil interfaces, and the 2D contact angle of carbonate with brine and oil. Our results show that these features (e.g., interface length, contact angles, effect of asperities) are present on the scale of a few tens of nanometers to a few micrometers, which is in agreement with numerous theoretical and experimental studies.
Lixhe limestone showed relatively less carbonate/oil contacts despite a larger oil fraction in the MgSO4-brine-flooded sample compared with the sample flooded with NaCl brine, indicating a more-hydrophilic nature of the carbonate surface in this experiment. This feasibility study showed that the technique permits the testing of predictions on the morphology and dynamics of contact lines in relation to the mineral properties, which is not possible with other imaging methods, such as X-ray microcomputed tomography (µ-CT), because of limits in resolution.
Stability of CO2 Displacement of an Immiscible Heavy Oil in a Reservoir
Authors: Tran Truynh Quoc , Neogi P.. , Bai Baojun 
Published: February 2017

Summary
Miscibility is not reached in carbon dioxide (CO2) flooding for recovery of heavy oils. Thus, an important advantage of no gas/oil surface tension is lost. Nevertheless, some CO2 continues to dissolve in oil and reduces the oil viscosity, which makes the displacement easier. This is an asset that remains. However, the viscosity of heavy crude is much higher than the viscosity of CO2, causing the displacement process to be unstable and leading to fingering or channeling. We have undertaken the linear-stability analysis of the displacement process, which is that of immiscible displacement but includes mass-transfer effects. All stabilizing/destabilizing mechanisms of both immiscible displacement and miscible displacement are included. A number of stabilizing mechanisms related to mass transfer have been identified. We are able to provide a numerical evaluation of the results that show the lowering of viscosity that is considered only in miscible displacement leads to a partial stabilizing effect that overcomes a large destabilizing effect of the adverse mobility ratio. There is a restricted form of instability that would only give rise to a mushy zone at the front. The two regions are separated at a wavenumber determined numerically as 0.531 cm−1. We are also able to show that in the limit that the solubility of CO2 in oil drops to zero, the above window of instability becomes infinite.
