ESP-DST Well Testing in a Complex Reservoir in the Barents Sea: Establishing New Methodologies and Lessons Learned
Authors: De Leonardis D. , Shumakov Y. , Morton K. L. , Sarac S.
Published: March 2017

This paper describes a unique combination of equipment and techniques that enabled an ESP-DST well test on a shallow, horizontal well drilled in a faulted and heterogeneous reservoir with complex fluids, in Arctic conditions.

The technical challenges of the performed well test included designing a bespoke ESP-DST string compatible with the shallow reservoir and designing a surface well test spread capable of efficient separation for safe and environmentally friendly disposal, and obtaining accurate flow rate measurements, as well as performing a test with interpretable data given the uncertainty and complexity of the formation, and the complexity of the well itself.

The success of the performed well test was the result of an integrated approach to well test design and real-time support provided throughout. This process included the selection of optimum ESP-DST string design for multizone testing in a high angle well including an innovative arrangement of an ESP encapsulated in a POD and installed in the riser. Integration of ESP with the surface well test package was also important and the design of the surface well test package included a Coriolis type of separator and multiphase flow meter for accurate flow rate measurements.

During drilling, the contingency plan to mitigate against losses was implemented which had a significant effect on the well testing program. To address this, and to understand if the well objectives could still be achieved, an uncertainty-based well test design and interpretation methodology, taking into account reservoir uncertainties and their interaction with each other, which uses numerical models and a global sensitivity analysis method was applied. This method identifies which uncertain reservoir parameters can be interpreted confidently and indicates the test duration. From the hundreds of numerical simulation cases produced during the design stage of the test, matches were obtained during monitoring to give an indication of the future pressure behavior, which allowed the duration of final build-up to be optimized.

The ESP-DST well test was successfully performed on a horizontal well drilled in the Wisting discovery in the Barents Sea. The well was successfully free flow tested giving a maximum achieved flow rate of 5,000 barrels of oil equivalent per day. All the well test objectives were successfully achieved, despite the change to the contingency drilling plan.
Optimizing Bean-Up Procedure after Well Shut-in. Simple Rock Mechanical Aspects and Operational Guidelines

Published: March 2017

Several theories exist for estimating permissible well drawdowns based on mechanical properties of the formation. These models are well developed and extensively used for the initiation of sand failure. However, models for predicting sand volumes and the sanding behavior post failure are plagued by difficulties in characterizing the mechanical properties of the failed/plastified area, the complicated interplay of erosion and production of sand on stress distribution in the near wellbore and from assumptions of idealized geometries. This work describes a method for determining optimum bean-up strategies that limit mobilization of material such as fines or sand from failed perforations/sand-face. The method nicely circumvents issues that can limit the applicability of theoretical models when optimizing well bean-up by simply ensuring that any transient pressure gradients that develop are lower than the pressure gradients that exist in near wellbore for the normal operating state of the well. The assumption is that the asset is operating the wells at flow rates/drawdown that are acceptable to them in terms of sanding/solids production. Such an approach can be used to minimize sand production during regular bean-ups for wells that are produced at ASR (Acceptable Sand Rates) and for wells where fines mobilization is suspected in causing time dependent skin effects and plugging. Different strategies are given to estimate the maximum step change increases in drawdown, the number of discrete steps and the total bean-up time. Furthermore, a method is presented showing how the pressure profile observed following a shut-in can be used to determine the optimum bean-up rate for any well - without knowing the exact details of the well and flow geometry or the different diffusivity coefficients and properties of the various producing layers. This is a new insight and can be a very powerful tool.

Published: March 2017

Managed pressure drilling (MPD) is an adaptive and sophisticated drilling process used to control the downhole and annular pressure. Mud management could enhance MPD as the downhole pressure is dependent on mud parameters such as mud density and rheology. Therefore, a step-change is needed in drilling process control, to enable consistently high performance, accurate pressure control and reduced risk of unwanted effects. Advances in process control have been made, but risk reduction and optimization of the drilling process is still a major challenge in the drilling industry.

A missing piece in considering the process-control puzzle is the in-situ determined drilling mud characteristics. Without accurate knowledge of mud properties and cuttings contents or without an ability to adjust the mud in real-time, a control system cannot reliably maintain bottom hole pressure or ensure a smooth flow of cuttings. The use of real-time density and rheology measurements in combination with a model that optimize the drilling operation by adjusting the mud will be a radically new innovation on the drilling market.

To complete the puzzle, a demonstration of a pilot unit will be carried out. The unit combines monitoring of mud and cuttings with wellbore hydraulic modelling and a control system that adjusts mud properties in real-time. The control setup will strive to keep the drilling operation within its operating envelope with respect to cuttings transport and bottomhole pressure. The demo project will construct such a system from existing components. Its focus will be on demonstrating the potential of a fully integrated drilling system. In particular to demonstrate that mud properties can be adjusted automatically based on real-time mud measurements. This demonstration project will be carried out in collaboration between Huisman, Statoil, SINTEF, Intelligent Mud Solutions (IMS) and Cybernetic Drilling Technology (CDT), with financial support from the Norwegian Research Council.

The demonstration project will take place at Huisman Innovative Tower in the Netherlands, where a full scale facility with drilling rig and a 400 m deep test well goes operational in Q1 2017. Available technology from the project partners covers many of the process control components. Such as a commercial hydraulic flow model for downhole pressure predictions provided by SINTEF, a mud density and rheology sensors provided by IMS with software by CDT and a mud treatment system of Huisman's design, allowing for real-time adjustment of mud.
Climate change and land use impacts on hydrologic processes of watershed systems
Authors: Talib Ammara , Randhir Timothy O.
Published: March 2017

Land use, land cover and climate change (CC) can significantly influence the hydrologic balance and biogeochemical processes of watershed systems. These changes can alter interception, evapotranspiration (ET), infiltration, soil moisture, water balance, and biogeochemical cycling of carbon, nitrogen, and other elements. The need to evaluate the combined effect of land use change and CC of watershed systems is a focus of this study. We simulated watershed processes in the SuAsCo River watershed in MA, USA, using a calibrated and validated Hydrological Simulation Program Fortran model. Climatic scenarios included downscaled regional projections from Global Climate Model models. The Land Transformation Model was used to project land use. Combined change in land cover and climate reduce ET with loss of vegetation. Changes in climate and land cover increase surface runoff significantly by 2100 as well as stream discharge. Combined change in land cover and climate cause 10% increase in peak volume with 7% increase in precipitation and 75% increase in effective impervious area. Climate and land use changes can intensify the water cycle and introduce seasonal changes in watershed systems. Understanding dynamic changes in watershed systems is critical for mitigation and adaptation options. We propose restoration strategies that can increase the resilience of watershed systems.
A comparison between pattern-based and neural network short-term water demand forecasting models
Authors: Gagliardi F. , Alvisi S. , Franchini M. , Guidorzi M.
Published: March 2017

In this paper, two models are set up in order to forecast hourly water demands up to 24 h ahead and are contrasted with each other. The first model (hereinafter referred to as the Patt model) is based on the representation of the periodic patterns that typically characterize water demands, such as seasonal and weekly patterns of daily water demands and daily patterns of hourly water demands. The second model is based on artificial neural networks (hereinafter referred to as ANN models). Both the models have been applied to three case studies, representing water distribution systems managed by HERA S.p.A., characterized by very different numbers of users served, and consequently very different average water demands, ranging from 900 L/s for the first case study (CS1) to about 8 L/s and1.5 L/s for the second (CS2) and third (CS3) case studies, respectively. The results show that in general, both the models, Patt and ANN, provide good accuracy for the CS1. The performances of both the models tend to decrease for CS2 and, particularly, for CS3. In particular, in the validation phase, the Patt model is more accurate than the ANN model for the CS1; for the CS2, the accuracy of the two models are very similar, and for the CS3 the accuracy of the ANN model is slightly higher than that of the Patt model.
Water masses surface temperatures assessment and their effect on surrounding environment
Authors: Calheiros Cristina S. C. , Barreira Eva , Ramos Nuno M. M. , Castro Paula M. L.
Published: March 2017

The aim of this study was to evaluate the effect of water masses on the surface temperature with direct impact on the surrounding area. Three systems were used for the study: a fully vegetated system (subsurface flow constructed wetland (CW)), a lake with no vegetation and a lake partially vegetated with Lemna minor. Infrared thermography was applied for the different systems analysis, allowing the determination of the surface temperature spatial distribution. In general, the presence of plants and water in the analyzed systems contributed to lowering the surface temperatures when comparing to its surroundings. Differences up to about 22 °C were observed in the temperature between the CW canopy and the surrounding soil, and up to about 19 °C between the lake and the surrounding border. Different plant species (Canna flaccida, Canna indica and Zantedeschia aethiopica) inhabiting the CW were also compared and slightly higher average surface temperatures were observed for C. indica. The above mentioned results are relevant in terms of supporting a strategy for water systems inclusion, for example a lake or a CW, in a site as means of having influence in the surface temperature and to some extent in the heat island effect supporting a sustainable environmental management.

Published: March 2017

The microorganism community that grows under duckweed shelter can play an important role on treatment processes. Therefore, the present study aimed to assess the zooplankton dynamic and microbial community in duckweed ponds (DPs) applied for domestic wastewater treatment under open field conditions. A pilot system comprised of two DPs in series (DP1 and DP2), with 10 m2 each, received domestic wastewater through a flow rate of 200 L·day−1. Thus, the system was monitored during 314 days through samples collected and analysed weekly. Also, the zooplankton organisms were identified and quantified. DNA sequencing was performed in order to identify the bacterial populations. The findings showed a high efficiency of nutrient removal with 93% and 91% of total phosphorus and total nitrogen, respectively. A high density of microcrustaceans was observed in DP1 reaching 4,700 org.100 mL−1 and rotifers (over than 32,000 org.100 mL−1) in DP2, that could be related to the low suspended solids concentration (<30 mg·L−1) and turbidity (<10 NTU). The bacterial community showed a strong heterogeneity between samples collected along the seasons. Through these findings, it is possible to realise that the understanding of ecology could help to enhance the operation and designs of DPs.

Published: March 2017

Constructed wetland is widely used to treat municipal sewage. However, lack of carbon source always constraints the application of constructed wetland in advanced tailwater treatment process. Bark was used as the filler and external carbon source of constructed wetland in the study, and the effects of hydraulic retention time (HRT) on NO3−−N removal efficiency and carbon release velocity were explored. Results showed that the NO3−−N removal process was steady in the constructed wetland filled with bark without additional carbon source. The NO3−−N removal efficiency and NO3−−N concentration presented a first-order reaction. The reaction rate constant k was 0.4 day−1. The relationship between NO3−−N removal efficiency (η) and HRT (t) was η = 1-e−0.4t, and η was increased with increasing of HRT. η reached a maximum of 77% at HRT of 4.48 days. η obtained the minimum of 20% at HRT of 0.75 days. The relationship between the carbon source releasing velocity (v) by bark and HRT was v = 0.53(1.62/t-1/t2) + 0.32. v increased first and then decreased with HRT increasing. The maximum v was detected at t = 1.12 days.

Published: March 2017

Thiourea is a typical nitrification inhibitor that shows a strong inhibitory effect against the biological nitrification process. The 50% inhibitory concentration (IC50) of thiourea on nitrification was determined to be 0.088 mg g VSS−1, and nitrifiers recovered from the thiourea inhibition after it was completely degraded. The thiourea-degrading ability of the sludge system was improved to 3.06 mg gVSS−1 h−1 through cultivation of thiourea-degrading bacteria by stepwise increasing the influent thiourea concentration. The dominant thiourea-degrading bacteria strain that used thiourea as the sole carbon and nitrogen source in the sludge system was identified as Pseudomonas sp. NCIMB. The results of this study will facilitate further research of the biodegradation characteristics of thiourea and similar pollutants.

Oral cavity melanoma is a common skin and subcutaneous tissue neoplasm in dogs, which has malignant behavior and originates from melanocytes. The diagnosis is made through the observation of clinical signs and histopathological examination. There are several treatment methods, such as surgical excision, cryotherapy, chemotherapy and radiotherapy, however, the prognosis is poor due to high relapse and metastatic power. In the mentioned work a case of metastatic melanoma in a dog is reported, with the presence of a tumor mass in the oral cavity, ulcerated and blackened, with apparent deformity of the face. Finally, the euthanasia of the animal was chosen due to the advanced state of the disease.

Obesity is a pathological condition characterized by an accumulation of fat that is greater than necessary in the body, capable of impairing good health and animal welfare. It can occur as a consequence of the overload of carbohydrate and fat supply, exceeding daily energy expenditure, castration, sedentary lifestyle, as well as endocrine and genetic problems. This variation in the epidemiology of obesity has contributed to a greater difficulty in identifying the primary cause of the disease. Therefore, the purpose of this review is to present the epidemiological and clinical aspects, the methods available for the diagnosis of obesity and some forms of treatment.

Published: March 2017

Over the last 25 years, researches in all aspects of ruminant nutrition were intensified. Forecasts indicate that in the year 2050 the world production and consumption of meat will be almost the double of the current volume, reaching 455 million tons per year. These projections are the result of human population growth, estimated at nine billion by the year 2050, and by the increasing of the purchasing power and quality of life will also increase the demand for animal protein. Relevant researches about feed efficiency, digestion and absorption processes, the development of new techniques for evaluating food and in-depth knowledge of ruminal microflora allow to the maximum use of nutrients for animals, also reducing the disposal of waste in the environment, another area of great concern. With a theme with such importance, the aim of this paper is to perform a brief explanation about the "State of Art of Ruminant Nutrition". Given the vast potential of research, we selected some current issues with global significance, especially with use in bovines, as the use of beta-agonists, use of essential and functional oils and the use of molecular biology techniques to study the microflora rumen.
The Analysis of Scheduling Algorithms in Microcellular 4G MIMO WINNER System
Authors: Sroka Paweł , Długaszewski Zbigniew
Published: March 2017

In this paper impact of resource scheduling algorithms on the in the microcellular 4G environment has been analyzed. Among studied metrics were average user throughput,average cell’s capacity and the quality of provided services,which has been defined as a percentage of users achieving given data rate with defined error rate. Well known memoryless scheduling algorithms such as Round Robin, MaxSNR and Fair Rate have been compared with the algorithms proposed for fading channels in [1], namely Proportional Fair and Score Based algorithms. The latter algorithms take into account both history of the scheduled users and channel conditions. A simple modification has been proposed for all examined scheduling algorithms and its impact on the users and system performance has been analyzed. The above modification rely on a preselection of scheduled users, thus significantly reducing number of computations at the cost of some performance loss.Presented results have been obtained for both uplink anddownlink OFDMA transmission in the multipath MIMOchannels in the Metropolitan Area scenario proposed within the WINNER project. Only the frequency adaptive transmission mode has been considered.
Optimal Share Factors in the Push-Sum Algorithm for Ring and Random Geometric Graph Sensor Networks
Authors: Zanaj Elma , Baldi Marco , Chiaraluce Franco
Published: March 2017

The convergence speed of an asynchronous point-to-point version of the push-sum algorithm in sensor networks is investigated both through numerical simulations and theoretical arguments. The main contribution of the paper consists in studying the application of such algorithm in realistic scenarios, represented by non fully-meshed networks. Simulations show that, in this case, convergence may be strongly dependent on the adopted share factor, whose value should be optimized as a function of the connectivity level of the network. Optimum shares are derived for some common topologies, like the ring and the random geometric graph. The effect of possible link failures is also investigated.
A Dynamic Interference-Avoidance Algorithm for Frequency Hopping Systems
Authors: Stojan Ivo
Published: March 2017

In this paper we investigate an algorithm for the Adaptive Frequency Hopping mechanism that is used by frequency dynamic systems to mitigate interference from othersystems. With this algorithm we introduce several improvements in relation to the existing algorithms that are based on the approach of using Packet Error Rate as the means for channel classification. One is the use of a single criterion for channel classification regardless of the dynamics of interfering systems, which adds more flexibility and reduces the risk of erroneous channel classification. The second is the introduction of the concept of channel probing which ensures that channels that areexcluded from the hopset are not used until they are clear from interference. The third improvement is the parameterization of the algorithm, which enables the control of the trade off between the main achievements of the algorithm: throughput and quickness of adaptation to changing interference. We show these achievements of the proposed algorithm through simulation.
Topology Control Using Distributed Power Management Algorithm for Mobile Ad Hoc Networks
Authors: Pradhan Nuraj , Saadawi Tarek
Published: March 2017

In order to be strongly connected in the network, a node may increase its power indiscriminately causing interference. Since interference is one of the major problems in wireless network, the proposed algorithm will co-operatively reduce inter-node interference in the network. Further, uni-directional links are a major source of interference as most of the routing protocol only utilizes bi-directional links. The algorithm will attempt to prevent such links or if required convert them into bi-directional links. We will show that the proposed algorithm provides strongly connected and more reliable network over dynamic physical channel modeled by log-distance path loss model, log-normal shadowing model and rayleigh fading model. It stabilizes node connectivity over the dynamic network and environment and even, to a certain extent, prevent node from being completely disconnected from the network. For the selected simulation environment, we will show that the proposed algorithm provides a shorter packet delay, improves the network throughput by as much as 37%, decreases the routing overhead and reduces interference.
Regularized MIMO Decoders
Authors: Alghoniemy Masoud
Published: March 2017

In the Multi Input Multi Output (MIMO) antenna system, it is known that the Linear Minimum Mean Squared Error (MMSE) receiver is equivalent to Tikhonov regularization.Given that, we develop a family of generalized receivers based on regularization with different penalty functions that penalize the received symbols outside the convex hull of the modulating constellation. For illustration purposes we consider two types of penalty functions, the deadzone and infinity norm penalty functions. The proposed decoders have low complexity and can be implemented efficiently using convex optimization algorithms. Simulation results show that the proposed receivers outperform the MMSE receiver by as high as 5-dB at low Signal to Noise Ratio (SNR).
Secure and Efficient IPv4/IPv6 Handovers Using Host-Based Identifier-Locator Split
Authors: Varjonen Samu , Komu Miika , Gurtov Andrei
Published: March 2017

Internet architecture is facing at least three major challenges. First, it is running out of IPv4 addresses. IPv6 offers a long-term solution to the problem by offering a vast amount of addresses but is neither supported widely by networking software nor has been deployed widely in different networks. Second, end-to-end connectivity is broken by the introduction of NATs, originally invented to circumvent the IPv4 address depletion. Third, the Internet architecture lacks a mechanism that supports end-host mobility and multihoming in a coherent way between IPv4 and IPv6 networks. We argue that an identifier-locator split can solve these three problems based on our experimentation with the Host Identity Protocol. The split separates upper layer identifiers from lower network layer identifiers, thus enabling network-location and IPversionindependent applications. Our contribution consists of recommendations to the present HIP standards to utilize cross-family mobility more efficiently based on our implementation experiences. To the best of our knowledge we are also the first ones to show a performance evaluation of HIP-based cross-family handovers.
Mapping SDL Specification Fundamentals to Core SDL Ontology
Authors: Bagić Babac Marina , Kunštić Marijan
Published: March 2017

This paper gives a contribution in the efforts of Semantic web ontology development. We have developed the core ontology for Specification and Description Language (SDL),an object-oriented, formal language defined by the International Telecommunications Union Telecommunications Standardization Sector (ITU-T) as recommendation Z.100. The language is intended for the specification of complex, event-driven, real-time, and interactive applications involving many concurrent activitiesthat communicate using discrete signals. Using SDL formal model for system specification we bridge the gap between ideas in our minds and the actual implementation of the system. Being visually appealing SDL provides us with a simple tool for communication either between the softwaredevelopers or between non-experts without advanced engineering skills. In this paper we propose the ontology for the basic SDL system and process elements. We also propose a formal framework of SDL Markup Language as a medium for translating SDL model to SDL ontology.

POLÍTICA, ECONOMIA, SOCIEDADE, FILOSOFIA E CIÊNCIA: CORRELAÇÕES HISTÓRICAS NOS OITOCENTOS
Authors: Santos Fernando Santiago dos , Jusdensnaider Ivy
Published: March 2017

O século XIX foi um período histórico marcado por grandes transformações sociopolíticas, geográficas, filosóficas e científicas oriundas, em grande parte, dos ideais pós-revolução do século XVIII e da ascensão da burguesia. A formação dos Estados-nação europeus e a dominação imperialista do mundo por nações como Inglaterra, França, Itália, Rússia e Estados Unidos da América, associadas à crescente racionalização da ciência e aos avanços tecnológicos sem precedentes, são características indeléveis dos Oitocentos. A visão mecanicista do mundo e a tentativa de explicar os fenômenos sociais por meio dos métodos estatísticos também são fatores inerentes ao pensamento científico do período. O positivismo e as ideias revolucionárias de Charles Robert Darwin e Alfred Russel Wallace são, igualmente, marcas do século que, transformando a sociedade e a economia, também influenciaram o modo de pensar da atualidade.

DIÁLOGO CON CASTORIADIS
El proyecto de autonomía como horizonte para la emergencia de una subjetividad reflexiva, lúcida y deliberante
Authors: Negroni Paula Silvina
Published: March 2017

La política para Castoriadis, en tanto praxis transformadora, es viable en el marco de la significación autonomía, entendida como acción humana que, de modo lúcido, explícito consciente y reflexivo, trata de transformar las instituciones de la sociedad para hacer a la misma más autónoma, así como a sus individuos. Tal escenario conlleva la emergencia de un tipo de ser que interroga la regla de su propia institución y que pone en cuestión las significaciones centrales, develando su carácter arbitrario. Este es un ser social, colectivo anónimo creador del mundo. Mundo en tanto cosmos de sentido, cosmos de significaciones imaginarias, instituidas e instituyentes. El proyecto de autonomía en su doble dimensión, individual y colectiva, hace surgir a la filosofía como la libertad de pensar, como interrogación ilimitada y a la democracia como acto en el que la colectividad se autoinstituye de manera continua, rompiendo con la clausura de las significaciones. A partir de esa idea de autonomía se redefine el contenido posible del proyecto revolucionario como la búsqueda de una sociedad capaz de modificar en todo momento sus instituciones.

¿SERVILISMO O AUTONOMÍA? EL PROYECTO DE AUTONOMÍA FRENTE A LA NUEVA HETERONOMÍA
Authors: PROFUMI EMANUELE
Published: March 2017

La crítica de la descomposición de la sociedad que sostiene Castoriadis, y más precisamente la idea de un declive de la autorrepresentación de la sociedad, o de su dimensión social-histórica, es decir, su consistencia ontológica, debe ser revisada. La insignificancia de la sociedad contemporánea no puede jugar un rol central dentro del análisis crítico si pensamos que esta sociedad es también la expresión de una nueva heteronomía. Con las mismas categorías filosóficas de Castoriadis debemos rechazar la idea de descomposición y elaborar una crítica del presente. Para pensar la actualidad del “proyecto de autonomía”, el particular, es necesario sobre todo concentrarse en la naturaleza de esta nueva forma de dominación. Este trabajo crítico es urgente, si consideramos la actual bifurcación social-histórica de las sociedades occidentales: es necesario comprender la oposición entre democracia y capitalismo a través de la alternativa entre la servil y activa defensa del statu quo y una praxis de autonomía, base de esta bifurcación.
DIALÉCTICA DE LA SIGNIFICACIÓN Y DIALÉCTICA DEL PODER EN EL PENSAMIENTO POLÍTICO DE CORNELIUS CASTORIADIS

Partimos tratando la dialéctica entre poder y significación, esto es, mostrando cuáles son las relaciones entre constituir sentido, dar significación, otorgar validez, y el poder. Cómo dicha relación interviene desde la génesis del sujeto social, cómo se va dando el movimiento de la palabra y el poder en la medida en que desde las distintas etapas de constitución del psiquismo se va fraguando un sujeto “apto” para desenvolverse en un medio social. Continuamos tematizando qué tipo de subjetividad podría poner en cuestión las significaciones imaginarias sociales instituidas en una constelación social determinada y cuál es la relación de esta subjetividad que denominaremos “subjetividad reflexiva y deliberante”, con el proyecto de sociedad autónoma que plantea Castoriadis y con la concreción política de dicho proyecto en el régimen democrático. Finalizamos mostrando en qué sentido la democracia como régimen, planteada por Castoriadis, se constituye en una teoría crítica de la sociedad.

Sociología de la dominación vs. filosofía de la emancipación
Authors: Cervera-Marzal Manuel
Published: March 2017

El presente artículo explora la siguiente afirmación: los pensamientos críticoscontemporáneos están en crisis. Estos se escinden en dos polos que conducencada uno a un callejón sin salida. De un lado, las corrientes de pensamientofocalizadas en la crítica de los mecanismos de sujeción tienden a cosificar a estosúltimos al punto de obstruir la posibilidad de liberarse. Del otro lado, lospensamientos alternativos al proceso de resistencia y de subjetivación subestimandemasiado la pregnancia de las estructuras de opresión. Si las “críticas de ladominación”- de las que la sociología bourdiesiana constituye un arquetipo –pecan por fatalismo, los “pensamientos de la emancipación” – de los que lafilosofía rancieriana es el mejor ejemplo – presentan un exceso de irenismo. Laraíz de esta doble encrucijada reside en el error conceptual consistente en partirde una impermeabilidad absoluta entre los conceptos de dominación y deemancipación. La obra del filósofo francés Miguel Abensour ayuda a salir de estacrisis. Para ello, conviene cambiar la perspectiva, a fin de reconocer la existenciade una complicidad secreta entre la libertad y la servidumbre.

APOCALIPSIS: ¿CATÁSTROFE FINAL, REVELACIÓN FINAL O CATÁSTROFE FINALMENTE REVELADORA?
Authors: Candel Miguel
Published: March 2017

Como no todo el mundo sabe, ‘apocalipsis’ es un término griego que significasimplemente “revelación”. Ahora bien, al haber sido empleado, supuestamente,por el apóstol Juan como título de su alegórica descripción del llamado “fin delmundo”, la palabra en cuestión ha acabado significando precisamente eso: unacatástrofe final que acaba con todo el orden existente. En este breve artículopasamos revista a algunas de las visiones catastrofistas que circulan actualmentesobre el destino de la sociedad humana, visiones alentadas por una crisismultidimensional aparentemente sin salida.

LA AGONÍA DE LA CREATIVIDAD REPRESENTACIONES DE LO APOCALÍPTICO EN DAY OF THE DEAD DE GEORGE A. ROMERO
Authors: Aldegani Emiliano
Published: March 2017

El presente trabajo se propone recuperar algunas notas particulares del cine de G.A. Romero en relación a su representación del derrumbe del sistema social, con elfin de explorar su potencial crítico para denunciar los excesos e inconsistenciasdel imaginario capitalista y de la sociedad de consumo. Es decir, observar el modoen el que distintos elementos son presentados en el ámbito de la ciencia ficción, yel paralelo que establecen con algunos diagnósticos de las ciencias sociales, y enparticular de la filosofía, sobre la crisis cultural que experimentan las sociedadesoccidentales a partir del debilitamiento de sus instituciones centrales.Para ello el trabajo abordará la perspectiva que presenta el cine de Romerodeterminado agotamiento del mundo, expresado bajo la metáfora del apocalipsiszombi, en particular, en el contraste que se ofrece entre dos imágenes que sepresentan en las primeras escenas de su film Day of the Dead (1985). A su vez,recuperando la conceptualización de la figura del zombi que se ha establecidorecientemente en diferentes ensayos críticos, el trabajo busca recuperar larelevancia que la mimesis, como conducta social, manifiesta en la caracterizacióndel zombi romeriano y la centralidad de este aspecto en relación a los fenómenossociales a los que su cine se asocia.Las corrientes de filosofía crítica que se recuperarán se identificanprincipalmente con el diagnóstico que estableciera tempranamente la filosofía deFriedrich Nietzsche en sus observaciones sobre la historia y la dificultad de lassociedades occidentales para generar cultura, y a partir de esta lectura, serecuperarán también los aportes teóricos de Cornelius Castoriadis y del el filósofosur coreano Byung-Chul Han.
LO POLÍTICO EN EL PENSAMIENTO DE EMMANUEL LÉVINAS: UNA LECTURA DE TOTALIDAD E INFINITO
Authors: Granados-García Alejandro
Published: March 2017

Este artículo explora las implicaciones políticas del pensamiento de Emmanuel Lévinas (1906-1995), a partir de una lectura de su obra Totalidad e Infinito. Se observa que todopensamiento e implicación política en Lévinas cuenta con un fundamento ético, que a suvez se configura a partir de la idea de Infinito y del Deseo metafísico de lo absolutamente Otro a que da lugar. El pensamiento de este filósofo de origen lituano nos invita arecuperar la humanidad y, en consecuencia, a no permitir que se instaure la inhumanidaden nuestras interacciones, desde una subjetividad capaz de hacerse cargo éticamente del Otro. Esto obliga a buscar estrategias concretas para instaurar en la cotidianidadrelaciones políticas de hospitalidad y respeto por la pluralidad. Partiendo de laperspectiva de una antropología de la fragilidad, no habría otro camino que poner encomún las fragilidades y, al hacerlo, procurar crear un mundo habitable entre-todos.
MONTAGEM MNEMOSYNE, PAINÉIS DIDÁTICOS E CAVALETES DE VIDRO: APROXIMAÇÕES POSSÍVEIS
Authors: Bonfiglioli Cristina Pontes
Published: March 2017

Este ensaio apresenta a hipótese da relação entre o pensamento de Lina Bo Bardi e o deAby Warburg em momentos específicos da produção intelectual de ambos: a organizaçãoinacabada do Atlas Mnemosyne de Warburg, e os Painéis Didáticos e cavaletes de vidro deLina Bo Bardi. Aborda-se a coincidência do pensamento no que se refere à preocupaçãode ambos com o uso de imagens da cultura para produção de ambiências quepromovessem o encontro com o novo, que incentivassem a rememoração de imaginários eque configurassem a arte como um conjunto de imagens constitutivas da cultura humanaexpressa diversamente por diferentes povos do mundo e não como uma cronologia queorganiza o “progresso estético” da humanidade, baseando-se na erudição acerca do belo edo gosto, exclusiva de iniciados. Trata-se de aproximar dois pensadores do século XX apartir da visão não-estetizante da arte e da cultura que marcou seus trabalhos.

Authors: Rosa Marcelo Prado Amaral , Mendes Michel , Fenner Roniere dos Santos
Published: March 2017

Os jogos e a educação eram conquistas pelas quais os gregos apresentam estima. Dentreos jogos, destacam-se os de caráter competitivo, conhecidos como âgon – por possuíremregras, e de diversão, conhecidos por Paidia – jogos sem regras, destinados às crianças. Jána educação, Paideia, inicialmente buscavam a formação ideal para as crianças, o queposteriormente passa a ser concebido como uma formação completa, a formação dohomem. Dessa forma, o objetivo do trabalho é identificar as relações existentes entre ojogo (Paidia) e a educação (Paideia), com a finalidade de explorar as proximidades entretais esferas na educação, destacando a relevância do termo Paidia enquanto elementoformativo da Paideia grega. O trabalho possui abordagem teórica e salienta evidênciasque apontam a relevância do termo Paidia para a educação grega. Sublinha-se aexistência da relação de consequência entre a Paidia e Paideia, uma vez que a primeira secomporta como instrumento prévio de ensino sobre questões políticas e éticas do futurocidadão.
