Authors: Amri Khairul 
Published: February 2017

Tujuan riset ini adalah mengkaji hubungan antara kondisi oseanografi musiman (sebaran suhu permukaan laut, konsentrasi klorofil-a, pola arus, dan salinitas hasil pengukuran in situ dan data penginderaan jauh multi temporal tahun 2000, 2001, 2002, dan 2004) dengan hasil tangkapan ikan pelagis. Analisis dilakukan secara visual dan digital untuk mendapatkan gambaran dinamik kondisi oseanografi musiman perairan Selat Sunda. Hasil menunjukkan, nilai sebaran suhu permukaan laut Selat Sunda bervariasi sepanjang tahun, berkisar 27,0 sampai dengan 30,5°C. Salinitas berkisar 31,0 sampai dengan 33,7‰ dengan nilai terendah (31,0‰) pada musim barat sementara salinitas tertinggi (32,7 sampai dengan 33,7‰) ditemukan pada musim peralihan 2. Sebaran klorofil-a berkisar 0,1 sampai dengan 2,0 mg m 3. Musim barat merupakan musim dengan kandungan klorofil-a terendah (0,1 mg m-3) dan musim timur merupakan musim dengan tingkat kesuburan tertinggi (1,5 sampai dengan 2,0 mg m-3). Diduga peningkatan produktivitas primer yang sangat tinggi pada musim timur, selain akibat aliran massa air yang kaya nutrien dari Laut Jawa juga akibat upwelling pada mulut selat bagian selatan. Terdapat korelasi yang kuat antara peningkatan kosentrasi kesuburan perairan (klorofil-a tinggi 1,0 sampai dengan 1,5 mg m-3) akibat terjadi upwelling pada musim timur yang didukung oleh kondisi suhu permukaan laut hangat (29,0 sampai dengan 30,5°C) dan salinitas tinggi (32,7 sampai dengan 33,7‰) dengan diikuti peningkatan hasil tangkapan ikan. The current research aims to study the dynamic of the seasonal oceanography condition (sea surface temperature, chlorophyll-a concentration, sea surface height anomaly, and salinity by using in situ data and satellite multi temporal images until 2000, 2001, 2002, and 2004) in the Sunda Straits waters. The oceanographic data were analyzed by using visual and digital analyze to find the dynamic features. Results show that sea surface temperature was fluctuated with seasons. The values ranging from 27.0 to 30.5°C were higher than in situ measurement. The Surface salinity varied fluctuated from 31.0 to 33.7‰. Lower salinity (31.0‰) was found on the west monsoon, higher salinity (33.7‰) on the inter monsoon 2. The Concentration of chlorophyll-a ranged between 0.1 to 2.0 mg m-3 of which high abundance occurred with east monsoon. The high concentration of chlorophyll-a in east monsoon might be correlated to the nutrient transport impact from Java Sea and also contribution of upwelling process in southern mouth of Sunda Strait. The result shows that the catch of pelagic fish had strong linear correlation with the primery productivity (chlorophyll-a with high abundance 1.0 to 1.5 mg m-3) on upwelling process in east monsoon near south mouth of Sunda Straits with suported by warm water mass (sea surface temperature 29.0 to 30.5°C) and high salinity (32.7 to 33.7‰).

Lofs Wife Syndrome and Double Publics in South Africa

Published: February 2017

In a Compelling Reading of Sol Plaatje's Native Life in South Africa, Bhekizizwe Peterson Remarks on the Work's Inscription of multiple imagined readers with different investments in the narrative (79). Quoting from Jean-Paul Sartre's reflections on the intricacies of addressing fractured, and sometimes future, publics, Peterson writes:[T]he works of writers who find themselves on the “margin of the privileged class” contain a “double simultaneous postulation,” a consequence of the “fracture” in the “actual public” in which their art is produced and consumed. Because the “real public” consists largely of the conservative forces that compose the dominant class and ideology, the marginal writer is compelled to address “the progressive forces, or the virtual public” even if “the oppressed classes have neither the leisure nor the taste for reading.” In engaging the future and its virtual public—“an emptiness to be filled in, an aspiration”—the writing exceeds its actual limits and extends itself step by step to the infinite.

Published: February 2017

La Formación Profesional, ha sido la gran olvidada de todas las reformas educativas en España, teniendo asociadas unas connotaciones de menor rango social que estudios universitarios. Por ello, el doble germen de esta investigación sería la necesidad de redescubrir esta Etapa Educativa y, por otro lado, ir incrementando las aportaciones científicas a la Comunidad Educativa, ya que de unos años acá, está tomando auge y relevancia laboral.
En este trabajo, partiendo de un conocimiento general de esta etapa educativa en la actualidad, nos hemos planteado conocer el punto de vista del alumnado y profesorado sobre dos dimensiones como son “Gestión Curricular” y “Docencia y Tutoría” en este módulo (como parte de un estudio más amplio), y así poder identificar los problemas y sus posibles soluciones con el objeto de mejorar la formación profesional de los futuros Técnicos Superiores en Administración y Finanzas en Andalucía -España-.
De los resultados obtenidos se desprende que el profesorado opta por valoraciones considerablemente más elevadas que el alumnado, para valorar su trabajo en estas dos dimensiones, existiendo una diferencia de 1,02 puntos en la Dimensión “Gestión Curricular” y 0,90 puntos en la Dimensión “Docencia y Tutoría”, entre ambas muestras. Por todo ello, pensamos que necesitamos una reforma pedagógica de la Formación Profesional para devolver la capacitación e imagen social de la misma.
Gramaticalização do verbo danar como marcador aspectual: um legado latino

Published: February 2017

Apoiado teoricamente nos pressupostos da Linguística Cognitiva e da Gramática de Construções, este texto se propõe a discutir a hipótese de que a construção aspectual formada de V1danar + (prep) + V2infinitivo tem raízes latinas, dado que construções sintáticas semelhantes já eram identificadas no século I da Era Cristã. Os resultados alcançados demonstraram que tal construção emergiu com a função aspectual no século XX, mas que ela resulta de um processo de mesclagem das duas construções latinas que a precederam historicamente, das quais herdou traços sintáticos e semânticos.

Authors: Hui Yang , Xiangli Cui , Xin Wang , Shuang Qiu , Lihong Liu 
Published: February 2017

Objectives：We conducted a systematic review and meta-analysis to compare the clinical outcomes of patients after liver transplantation accepting antiviral prophylaxis (AP) or preemptive therapy (PT) for preventing cytomegalovirus (CMV) disease. Methods: A literature search of PubMed, Cochrane, Embase was conducted up to June 1, 2016. References of the retrieved articles were also reviewed and relevant studies were included. The primary outcomes were incidence of CMV infection, incidence of CMV disease, mortality and opportunistic infection. The second outcomes were the mean time to CMV infection and CMV disease, adverse drug reaction (ADR). Sensitivity analysis and publication bias were evaluated. Results: 6 cohort studies involving 1091 liver-transplant recipients (LTRs) were included. All studies were with high quality according to Newcastle-Ottawa Scales (NOS). Incidence of CMV infection and CMV disease showed significant difference between the AP and PT in high-risk patients. There was no significant difference of CMV-related mortality (725 patients, OR 1.27, 95%CI 0.12-13.47, p=0.84) and other opportunistic infections (311 patients, OR 0.85, 95%CI 0.49-1.45, p=0.55) in all “at-risk” patients between the two strategies, whereas late-onset CMV infection and CMV disease were found in patients receiving AP. Conclusion: We recommended the use of AP instead of PT in the high risk patients, and PT could be used in moderate or low risk patients for the similar clinical outcomes in preventing CMV disease. RCTs comparing the two strategies are warranted. This article is open to POST-PUBLICATION REVIEW.

The Strategies of Academic Library to Serve Net-Generation
Authors: Setiawan Chandra Pratama 
Published: February 2017

The fast developments in information and communication technology have rapidly shaped and created enormous changes in the way people live and use libraries. The generation who grow in this era is called net generation. Academic libraries, where the majority of the users are the net-generation, have started to implement the concept of hybrid library as a response of the technological advances. The trend of digital collections usage is getting increase, on the other hand, the number of library visitor is getting lower significantly. The condition make librarians afraid of being abandoned by its users, whereas libraries still have many physical collections. This paper is written as a result of simple observation in some libraries where the needs of net-generation has accommodated. The concept of library as place, and library marketing offer the solutions to deal with the problem. Libraries can develop and provide some facilities that suitable with the net-generation characteristics. In addition, libraries can create some events to promote their services even the collections to attract the users to visit library.
Implementation of a Vertex-Centered Method Inside an Industrial Reservoir Simulator: Practical Issues and Comprehensive Comparison With Corner-Point Grids and Perpendicular-Bisector-Grid Models on a Field Case
Authors: Samier Pierre , Masson Roland 
Published: February 2017

Summary
Corner-point grids (CPGs) and pillar-based unstructured grids do not provide an effective work flow for translating Earth models into simulation models. Such a work flow requires grids that allow an accurate representation of the near-well flow, preserve geological accuracy, and offer flexible resolution control. Hence, a 3D unstructured approach is required.
Significant work has been performed for generating unstructured grids, and modeling hydraulic-fracture flow for gas-shale simulation has given a new impulse for unstructured gridding. Recent methods such as vertex-approximate gradient (VAG) or more-mature ones such as multipoint flux approximation (MPFA) provide a numerical scheme dependent on multipoint stencil more physical than two-point flux-approximation (TPFA) methods.
This paper presents the implementation of VAG and MPFA schemes inside a next-generation reservoir simulator starting from a source code calculating multipoint flux nonneighbor connections (NNCs) for any polygonal-shaped control volume.
The unstructured-scheme approach has been developed as an in-house extension to a next-generation multicompany collaborative reservoir simulator that is designed for handling unstructured grids.
The main issues addressed are the introduction of vertices unknowns among the usual cell-center variables, the assignment of vertices properties in the reservoir-simulator model, and the link with the well model.
Incidentally, the definition of an exchange format to describe the unstructured geometry (vertices, edges, faces, control volumes) on a large reservoir-simulation model is proposed.
Three simulation examples are presented, and we compare results, accuracy, and performance of multipoint-scheme methods such as VAG and MPFA on unstructured grids. Results are compared with TPFA methods on refined structured CPGs and TPFA methods on unstructured Voronoi grids. The two first test cases are academic models, and the third one is a field model.
Experimental Validation of a Pore-Scale-Derived Dimensionless Capillary Pressure Function for Imbibition Under Mixed-Wet Conditions
Authors: Zhou Y.. , Helland J. O. , Hatzignatiou D. G. , Ahsan R.. , Hiorth A.. 
Published: February 2017

Summary
We validate experimentally a dimensionless capillary pressure function for imbibition at mixed-wet conditions that we developed recently on the basis of pore-scale modeling in rock images. The difference from Leverett's traditional J-function is that our dimensionless function accounts for wettability and initial water saturation after primary drainage through area-averaged, effective contact angles that depend on the wetting property and distribution of oil- and water-wet grain surfaces. In the present work, we adopt the dimensionless function to scale imbibition capillary pressure data measured on mixed-wet sandstone and chalk cores. The measured data practically collapse to a unique curve when subjected to the dimensionless capillary pressure function. For each rock material, we use the average dimensionless curve to reproduce the measured capillary pressure curves and obtain excellent agreement. We also demonstrate two approaches to generate different capillary pressure curves at other mixed-wettability states than that available from the data used to generate the dimensionless curve. The first approach changes the shape of the spontaneous- and forced-imbibition segments of the capillary pressure curve whereas the saturation at zero capillary pressure is constant. The second approach shifts the vertical level of the entire capillary pressure curve, such that the Amott wetting index (and the saturation at zero capillary pressure) changes accordingly. Thus, integrating these two approaches with the dimensionless function yields increased flexibility to account for different mixed-wettability states. The validated dimensionless function scales mixed-wet capillary pressure curves from core samples accurately, which demonstrates its applicability to describe variations of wettability and permeability with capillary pressure in reservoir-simulation models. This allows for improved use of core experiments in predicting reservoir performance. Reservoir-simulation models can also use the dimensionless function together with existing capillary pressure correlations.
Chemical Stimulation Pilot at a Heavy-Oil Field: Key Considerations, Workflow, and Results

Published: February 2017

Abstract
This paper presents the planning and execution process for a key matrix stimulation pilot project performed in the heavy-oil Chichimene field in the central Colombian province of Meta. An understanding of multiple aspects of formation damage, candidate well selection, laboratory testing, treatment fluid selection, onsite quality assurance/quality control (QA/QC), diversion considerations, and placement techniques was fundamental to achieving a successful treatment design. Results are presented in terms of a percentage increase in production rates, percentage decrease in decline rates, and skin value reduction.
Because of current oil and gas industry economics, it is crucial to evaluate the return on investment for any well intervention campaign and apply an assurance process to help quantify the desired improvement in production results. This approach is primarily based on a workflow that includes several key steps: understanding the nature of and characterizing formation damage, reviewing necessary laboratory testing, validating candidate well selection, determining economically viable placement and diversion techniques, and performing QA/QC on site and post-treatment.
Production results from the first five pilot wells are presented along with a review of the production decline and continuous improvement actions. Understanding the induced damage that can be caused by drilling operations, heavy-oil properties, and the potential for emulsion and wettability alteration, in addition to the need to ensure total fluid-fluid compatibility combined with low interfacial tensions (IFTs), can be crucial to achieving results above initial estimates. Aligned with current critical well intervention economics, a rigless operation with coiled tubing (CT) through the Y-tool of an electrical submersible pump (ESP) was selected instead of a traditional intervention with a workover (WO) rig. Because of long treatment intervals and large permeability variations, stages of foamed brine were included in the treatment schedule as a diversion method. A tuned frequency and amplitude tool was used to enhance the placement and effectiveness of the treatment as part of a CT bottomhole assembly (BHA). QA/QC sampling was valuable for treatment monitoring and enhancement.
This paper presents a valuable basis for future candidate well selection and stimulation treatment design. The workflow and its application are a good reference for analogue fields in Colombia and other areas.
