Evaluating Hybrid Fire Suppression Systems for the Protection of Aero-derivative Gas Turbines
Authors: Christian Dan , Verstrynge Cedric
Published: June 2017

The purpose of this project was to evaluate the effectiveness of a hybrid inert gas/water mist fire suppression system on aero-derivative style gas turbines. A utility company and its fire protection engineer provided the opportunity to test the system on an operating unit under load, enabling the research team to assess system efficacy in real-world scenarios. The utility company established the test criteria; testing would be deemed successful if the system could cool the turbine skin to less than 380°F within 10 minutes. 380°F represents the auto ignition temperature of lube oil and turbine fuel plus a safety factor, as determined by the company. The 10-minute timeframe was established to match the performance of the existing CO2 extinguishing system.

A series of tests were devised to demonstrate the suppression system's effectiveness for cooling. The tests involved operating a Pratt and Whitney FT4 aero-derivative turbine generator off and on the power grid at full speed/base load and allowing the unit to cool naturally, as well as on the grid and allowing the system to discharge. Systematic changes in water flow and installation parameters were used to find optimal results. Temperatures were recorded at the compressor section, combustion section front, combustion section rear, hot turbine section, exhaust diffuser and in the enclosure.

Testing demonstrated that the hybrid fire suppression system is capable of quickly cooling the turbine skin to below 380°F—within 33 seconds, in fact—without damaging the turbine. The test results show successful cooling with the emitters installed overhead and aimed toward the hot section of the turbine. Results indicate that the hybrid fire suppression system adequately protects aero-derivative turbines under normal operating conditions. The testing offers a proof point that the system is not damaging to equipment, overcoming historic objections to the use of water mist style systems.

This paper will present a dedicated field case study that shows effective optimization of injection facilities obtained by hydraulic simulation. Water Injection Plants (WIPs) in the fields under study are operated as a secondary oil recovery method by means of peripheral injection. Field production strategy dictates water injection requirements in a given field. A core area of Field-A was identified with a need for increased injection pressure support. However, existing injection facilities could not meet the demand of increased injection rates. The injection capacity constraints were discerned by conducting a selective injection system capacity test. The feasibility of future improvements to the injection system using hydraulic simulation forecasts provided valuable and vital inputs. Accordingly, the most reliable and cost effective option was implemented in the field.

Hydraulic simulation along with network pipeline modelling was utilized on this case study with the objective of debottlenecking the overall injection system. Well performance models for the water injection wells to represent the reservoir inflow performance relationships (IPRs) were built. The most recent injectivity indices and static bottomhole pressures were used to construct the IPRs. Calibrations were then performed using current injection rates and wellhead pressures to history match the data and produce representative individual wells IPRs. On the other hand, piping network simulation incorporates surface injection lines sizes and ground elevation to account for pipe friction losses and gravitational pressure differences. Additionally, data from WIPs pump performance curves were inputted into the simulator to integrate surface and subsurface flow and capture the working mechanisms of the injection systems in this case study.

Surface piping network optimizations were achieved using the outputs of the hydraulic simulator runs and sensitivity analysis based on proposed corrective scenarios. The effect of these scenarios to the existing system was forecasted in terms of the ability to achieve the required individual wells injection targets. The simulated options were conceived on the following basis:

Utilizing an identified extra injection capacity from one of the WIPs. Looping the injected water through pipelines network connecting different WIPs. Constructing new injection lines to the field flanks that need additional injection.

Published: June 2017

Several steady-state multiphase flow modeling softwares have been utilized to optimize production pipelines and injection networks. These softwares lack suitable integration tools to incorporate geospatial data. Recently a new study was completed by integrating a modeling software with the Geographic Information Systems (GIS). GIS technology is widely used in oil and gas pipeline networks for data storage and retrieval purpose but not as an analysis and decision making tool. GIS handling of topographic and linear features was utilized for simulation purposes in the model. This study highlights the benefits of integrating pipeline simulation software with GIS on an existing complex surface production network. This integration became a tool that enables engineers to better manage field production and unlock production potential.

In order to improve the modeling of a field surface network with variable surface topography, an integrated wells model was constructed with the corresponding surface facilities. The integrated model took into account elevation profiles captured directly from the GIS and calibrated against field data. Over 40 oil wells and their respective flow lines were modeled, and then connected to the Gas/Oil Separation Plant (GOSP). The elevation aspect of the topography made the modeling results more reliable. To capture the value of this technique the results were analyzed against the existing network models that did not consider the elevation changes. The new technique honored the elevation of the wells with respect to the GOSP leading to unlocking more production potential.

The successful integration between GIS and the pipeline simulation software resulted in unlocking oil production potential and accurately modified choke adjustments. This methodology greatly improves the process of optimizing the existing pipeline networks by adding more layer of complexity to the models, which is topography. It also enables engineers to better plan future wells placement by taking into account the area topography.

Published: June 2017

Calcium carbonate scaling within well tubing and surface piping leads to significant production loss in many oilfields across the world. Scaling tendency of produced fluids increases multi-fold in a mature reservoir with increase in water production and decline in operating pressures. This paper demonstrates the use of modelling to help anticipate scaling issues and convert predictions into operational decisionmaking which has prevented significant value erosion in a mature field.

Majority of the efforts in tackling scaling related losses have traditionally been centered on performing scale treatment after observing a significant change in flow parameters. Although this approach delivers value, it is more reactive in nature and becomes challenging to address in a logistically constrained offshore environment. This paper presents a case study on a new proactive framework on Scale Management. This new framework is driven by P2P approach - Prediction to Prevention.

Prediction of scale formation tendency in wells was carried out using a thermodynamic model. Once wells with scale formation tendency were identified using thermodynamic model, scale prevention was done by selection and application of scale inhibitor chemical along with progressively reducing number of surgical acid washes. The scaling behavior was compared against the operating conditions of wells and the findings complemented the understanding from thermodynamic simulations. Paper deliberates on the cost optimization while application of this approach so that it remains extremely cost efficient in comparison to traditional approach. It details the evolution of scale management strategy right from project initiation to field maturation spanning across 30 years of production.

With periodic reviews of this framework, additional ~10% of available well stock was identified as new wells migrating into scaling envelope over the last one year and added to Scale Inhibitor dosage program. This prevented production losses and well integrity issues in these wells. Wells put on continuous scale inhibitor injection as per recommendations of this approach did not have down-hole safety valve failures, protecting 35% of field oil production volume and ensuring safer operations demonstrating strong business value. Overall, application of this P2P framework has helped asset to reduce yearly scaling related losses by more than 90%.
An Analytical Model to Evaluate the Capillary Trapping during CO2 Storage in Aquifers

Published: June 2017

Storage CO2 in brine aquifers is considered as a promising option to reduce CO2 emissions. Many simple analytical and semi-analytical techniques have been proposed to support screening analysis and performance assessment for potential carbon sequestration sites. However, these analytical techniques have ignored the capillary trapping mechanism, which is important to the carbon sequestration in aquifers.

In this paper, a new analytical method to evaluate the saturation profile and CO2 trapped quantity was derived. First, the fractional theory (Buckley–Leverett type model) is applied to simulate the multiphase flow. And the trapping and hysteresis models are adopted to model the capillary trapping mechanism. Then, the transient-pressure solution of injection well was solved by applying the quasisteady state theory. Subsequently, this analytical method is applied to evaluate the saturation profile and CO2 trapped quantity when gas alternating water (GAW) injection (strong imbibition phenomenon). After that, we applied this new analytical method in a real case to evaluate the CO2 capillary trapped quantity and assess the saturation profile. Finally, model verification and sensitivity analysis were conducted.

The results of model verification show satisfactory match and justifies, which shows our methodology is reasonable. Furthermore, the CO2 trapped quantity can account for about 24.25% of total trapped quantity, which indicates that the capillary trapping can't be ignored for long-term storage. In addition, results of sensitive analysis show that as the residual gas saturation increases, the capillary trapping capacity increases.

This work provides a new approach to the quick assessment of the capillary trapping quantity and the location of mobile gas left during gas alternating water injection.
The Impact of Salinity on Water Dynamics, Hydrocarbon Recovery and Formation Softening in Shale: Experimental study
Authors: Mehana Mohamed , AL Salman Mohamed , Fahes Mashhad
Published: June 2017

The low reocvery of Slick water used in hydraulic fracturing treatments and the better performance observed for low salinity floods reveal the impact of water dynamics on well and reservoir performance. The focus of this study has been to develop and implement an experimental workflow to investigate the impact of water salinity on wettability, hydrocarbon recovery and formation softening in shale rock samples varying in mineralogy. We are trying to provide a better understanding of the mechanisms of water dynamics and entrapement along with the driving forces associated with these mechanisms.

Samples from Woodford and Caney outcrops in the Unites States of America were obtained. The mineralogy of the cores was measured using the FTIR technique. While the Woodford samples turned out to be Dolomite rich, the Caney samples were Quartz and clay rich. Spontaneous imbibition and contact angle measurements were conducted for these samples using slickwater with an added KCl weight percentage of 0, 5 and 10. Both the rock-water-gas and the rock-water-oil systems were examined. The formation softening was quantified by recording the rock mechanical parameters before and after the imbibition and soaking tests. The results were analyzed in terms of the capillary suction characteristics for each formation.

According to the experimental results, a positive correlation was observed between water salinity and imbibition in Caney formation. However, the opposite was observed for Woodford samples. The formation mineralogy was identified to be the major factor in this reversal of wettability. Similar trends were observed for the recovery of both oil and gas where the low salinity imbibition yielded a higher recovery factor for the Caney formation samples and a lower recovery factor for Woodford. In addition, tangible increase in the compressive strength of Caney formation was reported with the increase in KCl concentration. However, a non-monotonic trend was observed for Woodford samples.

This study provides insights into the water dynamics in ultra-low permeability reservoirs. The formation mineralogy is a key factor for properly describing the water dynamics whether in fracturing treatments or in low salinity flooding projects. Low salinity flooding does not always imply better hydrocarbon recovery, based on what we observed in Woodford samples.
Effect of Carbonate Microfacies on Contact Angle: Study from Middle Jurassic Tuwaiq Mountain Formation
Authors: El-Yamani Mahmoud M. , Sultan Abdullah S. , Al-Ramadan Khalid A.
Published: June 2017

Tuwaiq Mountain Limestone Formation (TMLF) is an important Middle Jurassic formation in Saudi Arabia as it encompasses two reservoir rocks, one source rock, and unconventional reservoir in Jafura basin. It is important to characterize the rock fluid interaction properties of the different microfacies of TMLF. Different samples were taken from different microfacies; spiculitic wackstone, coral floatstone, coral rudstone, and foraminiferal wack/pack-stone. The selected samples have four different facies with variable mineral composition, mud ratio, sorting, roundness, different types of porosities. Because of that, the petrophysical properties of different facies are different and this was governed by the different depositional and diagenetic controls on each microfacies. These differences affect the rock fluid interaction in terms of contact angle and adhesion forces between surface of rock plate and oil.

The study showed that the difference in concentration of major and trace elements (especially Al+3, Mn+3 and Fe) in different microfacies controlled the difference in contact angle measurements. This difference is governed by the effect of the binding energy of Al+3, Mn+3 and Fe with polar substances in oil which in turn affect the oil adhesion on the rock surface. Also, it should be noted that the composition of oil has an interaction with microfacies as in case that the oil doesn't have polar substance (Resins and Asphaltenes), the differences in the concentration of major and trace elements in different microfacies might not have any effect adhesion and thus wettability and contact angle measurements.

Published: June 2017

Water-based drilling fluids are utilized to carry out efficient and smooth drilling operations of oil and gas wells. Bentonite is a basic constituent of water-based drilling fluids. It has excellent swelling properties, ability to make gel structure and acts as viscosifier to tailor the rheological properties of drilling fluids. Deep well drilling with bentonite drilling fluids at high temperature and pressure conditions will severely affect the performance of drilling fluid in term of degradation and flocculation due to thermal induce swelling of bentonite. High salts contamination during the drilling process reduces the hydration and dispersion of bentonite and results in flocculation.

The aim of this study was to improve bentonite drilling fluid performance using novel water-soluble polymers and nanoparticles. Nanoparticles significantly improved the filtration properties by reducing the fluid loss into formations and by making a thin filter cake for smooth drilling operations. Novel water-soluble polymers such as acrylamide/2-Acrylamido-2-methylpropane sulfonic acid copolymer and acrylamide/2-Acrylamido-2-methylpropane sulfonic acid/ N-Vinylpyrrolidone terpolymer were used to improve the rheological properties and dispersion of bentonite. Rheological and filtration properties were evaluated using functionalized carbon nanotubes and graphitized nanotubes by varying the temperature from 25°C-85°C. Herschel-Bulkley and Bingham model were used to calculate various parameters such as plastic viscosity and yield stress. It was observed that incorporation of 0.25 wt.% polymers and 0.25 wt.% nanoparticles improved the filtration and rheological properties such as yield stress and steady shear viscosity.
Petrophysical Joint Inversion for Reservoir Saturation Mapping: A Case Study
Authors: Alsaif Sarah , Marsala Alberto
Published: June 2017

Accurately estimating the fluid distribution in the reservoir is a key challenge in the oil industry. Well-log measurements are used to quantitatively characterize subsurface properties such as porosity and fluid saturation. It was proven that it is possible to reduce the ambiguity of the interpretation of well-log measurements by examining a common set of petrophysical parameters that relate geophysical attributes to rock properties. Simultaneously conciliating acoustic velocity, density and electrical conductivity jointly in the interpretation of well logs and deep interwell measurements can significantly reduce the uncertainty of the interpretation and improve the prediction of the reservoir properties, such as saturation.

This study examines a Bayesian joint inversion approach linking rock properties with well-log measurements through constitutive equations. The procedure is applied on actual formation evaluation measurements from a carbonate reservoir in Saudi Arabia.
Productivity Enhancement from Acidizing Horizontal Wells Drilled in Thin Carbonate Reservoir Layers

Published: June 2017

This paper presents a careful integration of geomechanical and reservoir properties to avoid excessive fracture extension and achieve proper acid containment within a thin reservoir layer, yielding very successful results. In general, wells drilled in thin reservoir layers may not produce or sustain continuous production for an extended period, even though the reservoir may have good oil saturation and pressure support. Log derived mechanical properties and empirical correlations from lab test performed on numerous core plugs were compiled for geomechanical modeling. In addition to the density log integration, the dynamic and static mechanical properties were utilized to estimate the maximum and minimum horizontal stresses. The fracture gradient, wellhead injection pressure, acid volumes and operational requirements were determined to properly design the acid job to avoid fracturing the reservoir beyond its thickness, but effectively establishing communication between the reservoir and the bore hole. Well data gathering such as completion type, intervals to be acidized, and reservoir pressure were also incorporated during the workflow process. The approach was piloted in two wells.

The productivity improvement from the acidizing job for the cases presented, show effective results in terms of near-wellbore formation damage removal and flow capacity improvement. The selected wells, former intermittent producers, responded favorably to the acid pumped with a considerable increase in oil production. Water cut did not initially increase, reflecting the effective avoidance of fracture creation to connect to lower aquifer zones. The validity of the log derived mechanical properties and stress profiles, as well as the lab derived correlations confirmed the validity of properly characterizing the reservoir in terms of strength and stiffness.

Production improvement, modelling process and treatment have been captured and shared in this manuscript.

Published: June 2017

We present an integrated three-dimensional (3D) spillway model where the realistic and complicated river terrain is implemented by the platform CATIA (Computer Aided Three Dimensional Interactive Application). This integrated 3D spillway model allows for complicated topographic and geomorphic conditions and describes the spatial distribution of the spillway dam (upstream reservoir, downstream river channel and the spillway dam itself) precisely, thus making it a real alternative to the physical model. Furthermore, this model provides the premise and possibility of a full-scale simulation of the spillway flow, that is, it can not only be used to study the hydraulics on the spillway face, but also can be used to study the hydraulics along the downstream river channel and estimate the scour problem associated with both the spillway flow and downstream river channel. In this model, turbulence was simulated using RNG k−ɛ equations. The flow velocity and surface pressure from the numerical model were verified by the data from experiments. Moreover, the river flow was studied and flow velocities downstream were obtained. The scour formed downstream of a ski-jump was also studied in this study on the location and shape of a scour hole. In all, this study provides new approaches for solving relevant hydraulic engineering problems.

Published: June 2017

Uma literatura feita de imposturas históricas sobre o período da ditadura militar no Brasil freqüenta as universidades, formando a nova geração. São avaliações geralmente simpáticas ao período de exceção. Elas recuperam mitos, dos quais o mais referido é o êxito no plano econômico. No entanto, a observação das estatísticas econômicas da época demonstra que o possível êxito foi de breve tempo. Além disto, fontes históricas insuspeitas desmentem os acadêmicos que tentam reescrever outros aspectos daquela história, dentre eles a explicação conveniente de que o golpe de direita foi um contragolpe. A verdade, porém, é que estes textos estão nas escolas e universidades, com milhões de educandos os consultando como fontes científicas. Mais do que nunca, a educação depende de debates abertos e do contraditório. Palavras-chave: literatura; fontes históricas; Ditadura Militar.

Background/Aim. Tuberculosis in the second decade of the 21st century is an infectious disease with the highest mortality rate. In addition, in developed countries, pneumonia is the major couse of morbidity and mortality in adults. The aim of our study was to point out the differences and similarities between symptoms, laboratory parameters and clinical indicators in patients with pulmonary tuberculosis (PTB) and patients with pneumonia in the general population and in people belonging to the high risk groups for developing tuberculosis. Methods. This prospective study included patients with PTB (n = 70) and pneumonia (n = 75) treated at the Pulmonology Department of Clinical Hospital Center in Kosovska Mitrovica. Results. PTB was more frequent in men, 30?39 years of age (OR; 6:08), mainly from rural areas (p = 0.001), and with lower levels of education (p = 0.031). Pneumonia was more frequent in women older than 60 years of age (p = 0.0012). Night sweats (p = 0.001) and weight loss (p = 0.062) were significantly more frequent in patients with PTB, while chest pain (p = 0.001) and high temperature (p = 0.036) were more common in patients with pneumonia. X-ray changes in patients with PTB were located in the upper fields (p = 0.001), or appeared to be bilateral (p = 0.004). The strongest predictor associated with an increased risk of night sweats was diagnosed PTB (OR = 30.0). The chest pain was a predictor of pneumonia, unilateral changes (OR = 4.65) in the lower lung fields (OR = 0.08). Conclusion. Night sweats, weight loss and chest X-ray abnormalities in upper fields were significant indicators of PTB. Chest pain, fever and chest X-ray abnormalities in lower fields were significant indicators of pneumonia.

Background/Aim. Chlamydia trachomatis infection (CTI) is an increasing public health problem worldwide and is the most frequent sexually transmitted infection. Studies conducted in many armed forces worldwide showed that CTI is common within military population and generate significant healthcare costs. The aim of this study was to estimate the prevalence of CTI among members of the Serbian Armed Forces (SAF) and to determine risk factors for this infection. Methods. The study was designed as a cross-sectional survey and consisted of completing a questionnaire and chlamydial testing. The questionnaire was divided into two question groups: one was about demographic/service related characteristics and the other was about behavioral patterns/ habits. Chlamydia trachomatis real time polymerase chain reaction (Real-TM PCR) was used for detection of pathogen genome specific sequence in the male urethral swabs and in the female endocervical swabs. All data collected were used to compare military personnel with and without CTI. Risk factors independently associated with CTI were identified by the stepwise multivariate logistic regression analysis (MLRA) of variables selected by the univariate logistic regression analysis (ULRA), with a limit for entering and removing variables from the model at 0.05. Results. The overall prevalence of CTI was 55 of 356 respondents (15.4%; 95% CI 0.5?2.7%). The ULRA identified that CTI was significantly associated with several characteristics: number of sexual partners during previous year (p = 0.008), knowledge about symptoms of CTI (p = 0.035), tattooing (p = 0.035) and married or in stable relationship (p = 0.022). The MLRA revealed that number of different sexual partners during last year was independent risk factor of CTI (p = 0.026; OR : 0.344; 95% CI: 0.13?0.88). Conclusion. CTI is significant problem in male and female military personnel in the SAF. The number of different sexual partners during previous year was independently associated with CTI. These finding indicates that screening for CTI should be undertaken in the SAF, to reduce rates of CTI in the SAF and to prevent morbidity due to this infection.

ResumenThe presence of gender violence in the media has led to the misconception that it is a social problem of the twenty-first century. However, in the literature of the last century, it can be seen that this phenomenon has always been present. Through the analysis of the play for colored girls, written by Ntozake Shangue, this essay will explore the situation of African- American women in American society in the twentieth century, focusing on the constant presence and threat of sexual violence suffered by the seven protagonists in a society where they suffer double discrimination.Key words: sexual violence, African American, literature, trauma.Título en español: “Women Relinquish All Personal Rights in Front of a Man”: análisis de la violencia sexual en For Coloured Girls de Ntozake Shange.Resumen: La presencia de violencia de género en los medios de comunicación nos ha llevado a la idea errónea de que se trata de un problema social del siglo XXI, pero si nos sumergimos en la literatura del siglo pasado, descubriremos que este tema siempre ha estado presente. En este ensayo, exploraremos la situación de las mujeres afroamericanas en la sociedad estadounidense en el siglo XX a través del análisis de la obra de teatro for colored girls de Ntozake Shangue, centrándonos en la constante presencia y la amenaza de la violencia sexual que las siete protagonistas padecen en una sociedad donde son doblemente discriminadas.Palabras Clave: violencia sexual, afroamericana, literatura, trauma.

EMANCIPAZIONE FEMMINILE IN GRECIA E INFLUENZE STRANIERE. IL CASO DI KALLIRROI PARREN
Authors: Boubara Ada
Published: June 2017

The purpose of this paper is to examine the early beginnings of women’s emancipation in Greece. The rise of such a new consciousness was undoubtedly slow in the Greek context as the four century Ottoman rule had placed the female figure in a clearly subservient and passive role. The main focus of the essay is on the admirable writings and social activities of Kallirroi Parren, one of those Greek pioneering women who devoted their lives to the improvement of the position of the woman in a community still so largely connected with the past and not yet prepared to accept changes. Kallirroi Parren was fully aware of such boundaries and claimed for a moderate authonomy. Furthermore, the essay draws a parallel between the characters of Parren’s most meaningful book, Η Χειραφετημένη (The Emancipated Woman), with some of the characters described by Angelica Palli Bartolommei in her Racconti (Short Stories). The aim is to demonstrate how these distinguished women – one Greek and the other of Greek origin, whose family had moved to Italy – were sharing the same view on women’s rights although dwelling in different countries. In other words, two distinctive personalities but one single voice. The study ends by quoting the date and the causes of Parren’s death in order to honor the life of a woman who paved the way of women’s liberation in Greece, a path which was later followed by many other women who, like the great Cretean, made of such a battle a way of life.
EL DOBLE Y SU SUBVERSIÓN EN EL CORAZÓN DEL TÁRTARO DE ROSA MONTERO
Authors: García Armero Carmen
Published: June 2017

Una lectura literal de El corazón del tártaro (2001) de Rosa Montero podría darnos la impresión de que solo se narra el acoso sufrido por Sofía Zarzamala a manos de su hermano gemelo y el proceso de maduración por el que atraviesa la protagonista. Sin embargo, una lectura interdisciplinaria y psicoanalítica revela que nos encontramos ante una novela de doppelgänger, en la que el enfrentamiento de la protagonista con su doble no finaliza con su desintegración, sino con la posibilidad de alcanzar una personalidad integrada. A través de este personaje femenino, Montero cuestiona y subvierte la tradición literaria del doble. Palabras clave: doble, individuación, identidad, género, poder, patriarcado, memoria y tradición.  The Double and its Subversion in El Corazón del Tártaro by Rosa Montero Abstract: A literal reading of El corazón del tártaro (2001) by Rosa Montero could give us the impression that the novel just narrates the harassment inflicted on Sofía Zarzamala by her twin brother and the process of maturity that the main character goes through. However, an interdisciplinary and psychoanalytic approach reveals that this narrative can be read as a doppelgänger novel. The protagonist’s confrontation with her double does not end with her disintegration, but with the possibility of achieving an integrated personality. Through this feminine character, Montero questions and subverts the literary tradition of the double. Key words: double, individuation, identity, gender, power, patriarchy, memory and tradition.
ELENA E L’ALIBI DELLA VIOLENZA
Authors: Brescia Graziana
Published: June 2017

Riassunto: Lo scambio di lettere tra Elena e Paride nelle Eroidi di Ovidio rappresenta una nuova fase all'interno dell'ampia ricezione dell'episodio mitico del rapimento di Elena. Ovidio riscrive la storia dei due amanti sulla base del codice elegiaco, centrandosi specificatamente nel momento della seduzione da parte di Paride e riconfigurando le funzioni del sequestratore e della donna sedotta alla luce tanto dell'Ars amatoria come della tradizione giuridica. L'innocenza di Elena e il suo ruolo di vittima - e non complice- del raptus sono conferiti dall'uso di vis a nome di Paride, anche se - come il poeta spiega nella sua Ars- la violenza è solo simulata e, soprattutto, grata puellis.Parole chiave: Ovidio, Elena, Paride, abduzione, violenza, simulazione, complicità.  Elena and the Alibi of Violence (Ovidio, Heroides 16-17)Abstract: The letter exchange between Helen and Paris in Ovid’s Heroides is a new step in the long-standing reception of the mythical episode of the abduction of Helen. Ovid re-writes the story of the two lovers according to the elegiac code, focusing specifically on the seduction by Paris and re-shaping the roles of the abductor and the seduced woman in the light of both the Ars amatoria and the juridical tradition. Helen’s innocence and her role of victim – and not accomplice – of the raptus are granted by the use of vis on behalf of Paris, even if – as the poet teaches in his Ars – the violence is just simulated and, most of all, grata puellis.Key words: Ovid, Helen, Paris, abduction, violence, simulation, complicity.

Paper Bag Explosions: A Theory of Becoming from Zora Neale Hurston to Frantz Fanon
Authors: Davis Jade E
Published: June 2017

Sheila Malone’s work is both digital art piece and critical essay, which explores the queerness and the vibrating machine in light of both recent scholarship on objects and materiality and the author’s own work as a performance artist. Malone’s art cuts across and questions the divides between highbrow and lowbrow, permanence and ephemerality, the G-rated and the X-rated. The digital installation and accompanying essay understand the space of inbetweenness as a potential site for queer interventions into existing material orders.
On the Limits and Promise of New Materialist Philosophy
Authors: Tompkins Kyla Wazana
Published: June 2017

A response to the forum, “Emergent Critical Analytics for Alternative Humanities,” edited by Chris A. Eng and Amy K. King. Kyla Wazana Tompkins questions the structures informing claims of newness posed by discussions of “New Materialism.” She discusses the troubling ways in which these discourses, in turning toward the post- or non-human, can ironically reinforce assumptions about a universal human subject and elide considerations of gender, race, and power.
Review of Critical Marxism in Mexico: Adolfo Sánchez Vázquez and Bolivar Echeverría by Stefan Gandler (Haymarket)
Authors: Farr Arnold L
Published: June 2017

With this book, Stefan Gandler has made important contributions to the study of Marxism and critical social theory in Mexico. Regarding the first contribution, this book expands the theoretical tools and insights within the canon of Marxist thought. It does this by exposing American and European Marxists to two very important thinkers who have not yet been given much attention by Marxists outside of the Latin American context. The second contribution lies in Gandler’s exegetical work on the texts of these two thinkers, Adolfo Sánchez Vázquez and Bolívar Echeverría.
