Published: May 2016

Background. There is no clear idea of what factors determine the characteristics of pain in endometriosis. Scientific data on the relationship between morphological and functional features of heterotopic tissue, and the intensity of the pain syndrome is extremely small. Purposes and tasks. To determine the features of the morphological structure of endometrial infiltrates in women with chronic pelvic pain syndrome. Materials and methods. We examined 32 patients with infiltrative endometriosis. Pain intensity was determined in accordance with a 10-point visual analog scale (VAS). Preparation of material for histological study was carried out during the execution of the operating laparoscopy. Histological sections stained with hematoxylin and eosin. The study was conducted with increasing ×100. Histological examination was carried out a descriptive and semi-quantitative assessment of glandular-stromal component biopsy, infiltration of inflammatory cells number, as well as the presence of blood vessels (arterioles, venules). Statistical analysis of the material was carried out using the Microsoft Excel 2013 and Stastistica 10.0 for Windows. Results. During the correlation analysis of the relationship between the intensity of pain and the severity of the vascular component revealed a strong correlation (Rs = 0.71, p < 0.05). With the severity of glandular-stromal component biopsy revealed moderate correlation (Rs = 0.49, p < 0.05). With the severity of the inflammatory infiltration of a number of cells revealed that there is no correlation (Rs = -0.1, p > 0.05). Conclusions. In severe degree of pain severity predominated infiltrates a lot of glands and stroma expressed vascular component, multiple foci of hemorrhage and severe degree of infiltration of inflammatory cells number. When pain syndrome of moderate severity, as in mild, was found mostly poorly and moderately pronounced glandular-stromal component, and infiltration of inflammatory cells number.

Endometrial stem cells due to their therapeutic characteristics could to be an effective tool of cell technologies in reproductive medicine. The aim of the study was to determine the most therapeutically effective route of administration for endometrial stem cells suspension. The study was conducted in approved animal model of injured endometrium. To create the experimental model tissue pieces of autologous endometrium were implanted on the anterior abdominal wall peritoneum using general surgical techniques. Experimental group animals were treated with endometrial stem cells suspension; in the control animal group a placebo was used. Local and systemic routes of endometrial stem cells administration were compared. The direct injections of stem cells suspension in the endometrial implants were used as the local route of administration, the intravenous injections of stem cells suspension were used as a systemic route. Endometrial stem cells expansion didn’t depend on the routes of administration, whereas therapeutic effects of stem cells was more obvious in tissue pieces after local injection of stem cells.

The myelodysplastic syndromes (MDS) are primarily a disease of the elderly, but it is unclear whether aging itself is an independent contributor to the pathophysiology of these disorders. While the normal aged hematopoietic system and MDS share many features compared to young hematopoiesis, they also exhibit important differences. With the demonstration that mutations present in MDS can also be identified in healthy elderly individuals, it will be important to elucidate the differences and interactions between normal hematopoietic aging and MDS.

Published: May 2016

Triple negative breast cancer is the most aggressive subtype of breast cancer, characterized by a lack of targeted therapy. Neoadjuvant chemotherapy is used to understand disease biology; patients who attain a complete pathologic response have improved outcomes compared to those who have residual disease. Locoregional treatment options remain similar to other types of breast cancer. Further research to identify druggable targets is ongoing and new agents appear to be on the horizon.

Published: May 2016

Esophageal cancer is one of the deadliest known cancers worldwide, and its incidence in the US is increasing over time. As per the Surveillance, Epidemiology, and End Results (SEER) data, it contributes to about 2.5% of all cancer deaths. Patients with esophageal cancer often present with an advanced stage disease where the prognosis is not very favorable. The typical symptoms at diagnosis are dysphagia and or odynophagia. Patients with adenocarcinoma may have previous or continued symptoms of gastro-esophageal reflux disease. By the time these symptoms occur, the disease is usually advanced, thus explaining the limited success in improving prognosis and overall survival. One of the reasons for early spread and late diagnosis is the fact that unlike most other gastrointestinal conduits, it lacks the serosa, and hence its high potential to spread relatively sooner. Another factor that negatively affects prognosis is the proximity of the esophagus to the vital structures like the airway and major vessels, and therefore the tendency of the cancer to directly invade them. The vitality of these structures is also a surgeon’s major concern, and this sometimes jeopardizes the surgical approach and intervention while treating this cancer. The alarm symptoms in most cases precede the manifestations of advanced metastatic disease. Depending upon the location of the disease at different metastatic sites (usually lung and liver), in addition to the characteristic symptoms, this cancer may accordingly present with additional signs and symptoms. Whereas most patients present with typical symptoms such as dysphagia, weight loss and abdominal pain we herein report a patient whose primary presentation was left hemiparesis due to metastatic esophageal cancer to his brain. He did not report classical esophageal cancer symptoms prior to this neurologic presentation.

Published: May 2016

Este trabajo tuvo por objetivo evaluar la arena (A), el carbón activado (CA) y la zeolita (Z) como materiales filtrantes para valorar su efecto en reutilización para agricultura de aguas residuales tratadas de un ambiente árido. Para esto se construyeron 7 columnas de filtración: a) columna 1, 100 % de Z, b) columna 2, 100 % de CA (origen A), c) columna 3, 100 % de CA (origen B), d) columna 4, 100 % de A, e) columna 5, 50 % de Z sobre 50 % de CA, f) columna 6, 50 % de A sobre 50 % de CA, y g) columna 7, 50 % de Z sobre 50 % de A. En el afluente y efluente se evaluó boro (B), cloruro (Cl-), sulfato (SO4-2), calcio  (Ca+2), conductividad eléctrica (CE), pH y temperatura (T), junto a un grupo de metales pesados (As, Cd, Cu, Fe, Mn, Pb y Zn). Los resultados mostraron cómo el CA (de origen A o B) es capaz de remover boro a valores por debajo de 0,75 mg/L. Sin embargo, en una etapa inicial (primera quincena) los efluentes a este medio filtrante, presentaron un valor de CE mayor a 2,5 dS/m, y de pH mayor a 8,4, lo que seguramente traerá problemas para su aplicación en riego de cultivos. Por su parte, la arena, al ser de la región, presenta problemas de lixiviación de elementos, como el arsénico y el sodio, por lo que no debería utilizarse como material filtrante. Por el contrario, el único medio evaluado que tiene potencial de ser aplicado en la reducción de la salinidad es la zeolita. Este material filtrante, sin mezcla con otro, fue capaz de reducir hasta un 20 % el valor de la CE sin tener un efecto negativo en ninguno de los otros parámetros evaluados en este estudio, y además, sin mostrar un estado de saturación durante el tiempo de operación evaluado. En el caso de las columnas que utilizaron mezclas de materiales, no existe un efecto sinérgico para la eliminación de los parámetros de calidad del agua evaluados.

Published: May 2016

La creciente y enorme cantidad de datos, del orden de exabytes, generados por las aplicaciones empresariales actuales han originado conjuntos masivos de estos. Los sistemas de gestión de bases de datos (SGBD) NoSQL han surgido como una alternativa a los SGBD relacionales para la gestión de estos conjuntos. Entre los principales SGBD NoSQL está MongoDB. En este artículo se compara el rendimiento entre MongoDB y Oracle (uno de los principales SGBD que soporta bases de datos relacionales). La comparación se basa en las operaciones de inserción, consulta, actualización y borrado (CRUD, por sus siglas en inglés). Aunque se requieren experimentos más exhaustivos y muchos otros tipos de pruebas, los resultados ofrecen un punto de partida para el análisis de rendimiento en estos SGBD.

Published: May 2016

En esta investigación se evaluó la gestión de los residuos hospitalarios en una clínica privada de tercer nivel de complejidad de la ciudad de Cali, mediante el uso de una herramienta ponderada por un panel de expertos, basada en las normas colombianas y las recomendaciones de la Organización Mundial de la Salud para la gestión de los residuos hospitalarios. La herramienta evaluó la producción de residuos, la operatividad, capacitación y cumplimiento de compromisos de los involucrados en la gestión. Se diagnosticó previamente la gestión de los residuos en la clínica, se diseñó una herramienta en Excel, y se aplicó mensualmente entre los meses de junio y septiembre de 2013. Los resultados mensuales de la medición facilitaron la identificación de las fallas en la gestión y orientaron la toma de decisiones a los responsables, lo que permitió incrementar la fracción de residuos reciclables en 3%, reducir los residuos comunes en 2,4% y los peligrosos en 0,6%. Se redujo la producción de residuos en la Unidad de Cuidados Intensivos, de 3,87 kg/cama/día en junio, a 3,5 kg/cama/día en septiembre, y en hospitalización de 1,33 kg/cama/día a 1,25 kg/cama/día. La evaluación mensual de la gestión de estos residuos con el uso de la herramienta, permitió la identificación puntual de las fallas en la producción de residuos, el componente operativo, el programa de capacitaciones y el cumplimiento de compromisos por parte de los responsables de la gestión, lo cual entregó información valiosa para apoyar la toma de decisiones en busca de mejorar su desempeño.

Generation of Dc-dc Converters With Wide Conversion Range Based on the Multistate Switching Cell
Authors: Bastos George H. de A. , Sousa Jefferson M. de , Costa Levy F. , Bascopé René P. T.
Published: May 2016

This paper presents the conception of six nonisolated dc-dc converters with wide conversion range based on the multistate switching cell (WCR-MSSC). In order to achieve wide conversion range, the multiphase transformer that is part of the multistate switching cell (MSSC) aggregates coupled secondary windings with controlled rectifiers, which are then connected in series. Then, it is possible to minimize the voltage stresses across the switches, allowing the use of MOSFETs (metal oxide semiconductor field effect transistor) with reduced on-resistance RDS(on), thus implying the significant improvement of the converter efficiency. The operation principle, qualitative analysis, quantitative analysis, and design procedure are properly presented. An experimental prototype is also developed, whose ratings are: output power PO=3 kW, input voltage VIN=84 V and output voltage VO=400 V. Some important results are then discussed in order to validate the theoretical assumptions.

Authors: G. Gupta Uma , Gupta Ashok
Published: May 2016

If Big Data is to deliver on its big promises, a well-articulated vision must be developed in a collaborative way and effectively communicated to all key stakeholders. Without a guiding technology vision, the promise and benefits of Big Data will become elusive and lost to many organizations. The literature on Big Data frequently refers to the 5Vs of Big Data (Volume, Variety, Velocity, Veracity and Value). Based on a strategic framework, this paper adds another dimension to this important and widely used framework, namely Vision, and elaborates on the critical role of vision and its relationship and impact on the remaining Vs. Research shows that vision has a positive impact on organizational performance. Organizations that link vision with strategic information systems, such as Big Data applications, ga5in a sustainable competitive advantage in the marketplace. The importance of carefully defining, establishing and communicating the vision of Big Data to the entire organization and to key stakeholders in order to leverage Big Data for growth, profits, and sustainable competitive advantage is discussed.

Hypoxic-Ischemic Encephalopathy and Serum Magnesium Monitoring and Maintenance
Authors: Bell Susan Givens
Published: May 2016

ABSTRACT

Magnesium plays important roles in many physiologic functions including protein synthesis, bone development, and cell membrane function. There is some evidence to suggest a role for magnesium sulfate as a therapeutic neuroprotective agent along with therapeutic hypothermia in infants with hypoxic-ischemic encephalopathy, but studies are inconclusive. Ischemic insult and hypothermia may both play a role in altered magnesium levels in this population.
Links between Terrorism and Migration: An Exploration
Authors: Schmid Alex P.
Published: May 2016

This Research Paper explores and questions some assumed causal links between terrorism on the one hand and (forced and irregular) migration on the other. The paper delves into the role that state and non-state terrorism might have in causing migration as well as analysing if and how refugees’ camps and the diaspora community might be a target for radicalisation. One of the findings of the paper is how migration control for the control of terrorism is a widely used instrument; however, it might hurt bona fide migrants and legal foreign residents more than mala fide terrorists. Finally, this Research Paper offers recommendations that can go some way towards disentangling the issues of (refugee) migration and terrorism.
Underwater 3D Imaging Using a Fiber-Based Endoscopic System for Arthroscopic Surgery
Authors: Long Zhongjie ,   Department of Human and Artificial Intelligent Systems, University of Fukui, Nagamune Kouki ,   Beijing Information Science and Technology University,   Department of Orthopaedic Surgery, Kobe University
Published: May 2016

Arthroscopic surgery is a minimally invasive surgical procedure that is widely used on joints. However, conventional endoscope-based arthroscopic surgery does not provide stereoscopic information to the surgeon. To overcome this limitation, we have developed a modified endoscopic system that uses an optical fiber (1 mm diameter) for three-dimensional imaging of knee joints. Our endoscopic system is able to operate underwater in real time. It consists of a laser beam that is projected on the surface of the object to be imaged via an optical fiber. A prism is used to decrease the length and diameter of baseline and endoscope tube, respectively. The small diameter (8 mm) of our endoscope makes it extremely convenient for application in arthroscopic surgery. The feasibility of the proposed system has been demonstrated via experiments on synthetic knee joints.

Published: May 2016

Powered exoskeletons have been proposed and developed in various works with the aim of compensating for motor paralysis or reducing weight, workload, or metabolic energy consumption. However, development of the power-assist system depends on the development and evaluation of real powered exoskeletons, and few studies have evaluated the performance of the power-assist system by means of computer simulation. In this paper, we propose an evaluation framework based on computer simulation for the development of an effective power-assist system and demonstrate an analysis of a power-assisted upper-arm reaching movement. We employed the optimality principle to obtain the adapted movements of humans for power-assist systems and compared the performances of power- and non-power-assisted movements in terms of the evaluation index of the power-assist system.
Generating Trading Rules for Stock Markets Using Robust Genetic Network Programming and Portfolio Beta
Authors: Chen Yan ,   School of Statistics and Management, Shanghai University of Finance and Economics, Shi Zhihui
Published: May 2016

In this paper, Robust Genetic Network Programming (R-GNP) for generating trading rules for stocks is described. R-GNP is a new evolutionary algorithm, where solutions are represented using graph structures. It has been clarified that R-GNP works well especially in dynamic environments. In the proposed hybrid model, R-GNP is applied to generating stock trading rules with variance of fitness values. The unique point is that the generalization ability of R-GNP is improved by using the robust fitness function, which consists of the fitness functions with the original data and a good number of correlated data. Generally speaking, the hybrid intelligent system consists of three steps: priority selection by the portfolio β, optimization by the Genetic Relation Algorithm (GRA), and stock trading by R-GNP. In the simulations, the trading model is trained using the stock prices of 10 brands on the Tokyo Stock Exchange, and then the generalization ability is tested. From the simulation results, it is clarified that the trading rules created by the proposed R-GNP model obtain much higher profits than the traditional methods even in the world-wide financial crisis of 2007. Hence, its effectiveness has been confirmed.
Percent Body Fat Is More Predictive of Function After Total Joint Arthroplasty Than Body Mass Index
Authors: Ledford Cameron K. , Millikan Patrick D. , Nickel Brian T. , Green Cindy L. , Attarian David E. , Wellman Samuel S. , Bolognesi Michael P. , Queen Robin M.
Published: May 2016

Background:

Obesity has an important impact on the future of total joint arthroplasty; however, the definition and influence of obesity on surgical risks and outcomes remain controversial. Our hypothesis was that percent body fat was better than body mass index (BMI) at identifying clinical risks and patient-reported functional outcomes following arthroplasty.

Methods:

Clinical and functional outcomes were collected prospectively in 215 patients undergoing primary total knee arthroplasty (115 patients) or total hip arthroplasty (100 patients) at a mean time of twenty-four months (range, twelve to forty months). Clinical data included patient demographic characteristics, preoperative evaluation including measurements of BMI and percent body fat, intraoperative records, hospital course or events, and postoperative outpatient follow-up. Patient-reported outcomes were obtained through a series of questionnaires: a surgical satisfaction survey; the University of California, Los Angeles (UCLA) activity scale; the Knee Injury and Osteoarthritis Outcome Score (KOOS) for total knee arthroplasty; and the Hip Disability and Osteoarthritis Outcome Score (HOOS) for total hip arthroplasty. Multivariable regression models were used to identify significant body mass predictors of outcomes (p < 0.05).

Results:

Higher percent body fat predicted occurrence of any medical or surgical complication (odds ratio per one standard deviation increase, 1.58 [95% confidence interval, 1.04 to 2.40]; p = 0.033). Percent body fat was also a predictor of the UCLA activity score (risk ratio, 0.92 [95% confidence interval, 0.85 to 0.98]; p = 0.013) and pain scores (risk ratio, 1.18 [95% confidence interval, 1.03 to 1.36]; p = 0.017), and it trended toward significance for the surgical satisfaction score (odds ratio, 1.96 [95% confidence interval, 0.93 to 4.15]; p = 0.078), whereas BMI was not predictive of these functional outcomes. Additionally, with regard to surgical procedure-specific outcome scores, percent body fat was predictive of outcomes after total knee arthroplasty (KOOS pain, p = 0.015, and KOOS activities of daily living, p = 0.002), but not for those after total hip arthroplasty.

Conclusions:

Percent body fat should be considered when predicting clinical and functional outcomes at two years following total joint arthroplasty. Percent body fat may help surgeons to improve risk stratifications, to project patient-reported functional outcomes, and to better educate obese patients with regard to postoperative expectations prior to undergoing elective total joint arthroplasty.

Racial and Socioeconomic Disparities in Hip Fracture Care
Authors: Dy Christopher J. , Lane Joseph M. , Pan Ting Jung , Parks Michael L. , Lyman Stephen
Published: May 2016

Background:

Despite declines in both the incidence of and mortality following hip fracture, there are racial and socioeconomic disparities in treatment access and outcomes. We evaluated the presence and implications of disparities in delivery of care, hypothesizing that race and community socioeconomic characteristics would influence quality of care for patients with a hip fracture.

Methods:

We collected data from the New York State Department of Health Statewide Planning and Research Cooperative System (SPARCS), which prospectively captures information on all discharges from nonfederal acute-care hospitals in New York State. Records for 197,290 New York State residents who underwent surgery for a hip fracture between 1998 and 2010 in New York State were identified from SPARCS using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. Multivariable regression models were used to evaluate the association of patient characteristics, social deprivation, and hospital/surgeon volume with time from admission to surgery, in-hospital complications, readmission, and 1-year mortality.

Results:

After adjusting for patient and surgery characteristics, hospital/surgeon volume, social deprivation, and other variables, black patients were at greater risk for delayed surgery (odds ratio [OR] = 1.49; 95% confidence interval [CI] = 1.42, 1.57), a reoperation (hazard ratio [HR] = 1.21; CI = 1.11, 1.32), readmission (OR = 1.17; CI = 1.11, 1.22), and 1-year mortality (HR = 1.13; CI = 1.07, 1.21) than white patients. Subgroup analyses showed a greater risk for delayed surgery for black and Asian patients compared with white patients, regardless of social deprivation. Additionally, there was a greater risk for readmission for black patients compared with white patients, regardless of social deprivation. Compared with Medicare patients, Medicaid patients were at increased risk for delayed surgery (OR = 1.17; CI = 1.10, 1.24) whereas privately insured patients were at decreased risk for delayed surgery (OR = 0.77; CI = 0.74, 0.81), readmission (OR = 0.77; CI = 0.74, 0.81), complications (OR = 0.80; CI = 0.77, 0.84), and 1-year mortality (HR = 0.80; CI = 0.75, 0.85).

Conclusions:

There are race and insurance-based disparities in delivery of care for patients with hip fracture, some of which persist after adjusting for social deprivation. In addition to investigation into reasons contributing to disparities, targeted interventions should be developed to mitigate effects of disparities on patients at greatest risk.

Published: May 2016

➢ Atraumatic hip instability is an increasingly recognized source of pain and hip dysfunction. It can result from numerous causes, including femoroacetabular impingement, prior trauma, injury to the capsuloligamentous structures, and idiopathic etiologies.

➢ Occult hip instability can be a challenging diagnosis that requires careful attention to, and interpretation of, history, physical examination, and radiographic imaging findings.

➢ Iatrogenic hip instability is a potential complication of both open and arthroscopic hip-preserving surgical procedures that can have catastrophic results.

➢ Atraumatic hip instability is a pathologic entity that can be successfully addressed with open and arthroscopic procedures.
Tendinopathy and Tendon Rupture Associated with Statins
Authors: Deren Matthew E. , Klinge Stephen A. , Mukand Nita H. , Mukand Jon A.
Published: May 2016

➢ Use of statins may be associated with certain tendinopathies and tendon ruptures, especially of the Achilles, quadriceps, and distal biceps tendons.

➢ Tendinopathy usually occurs within the first year of statin use and improves after the drug therapy is stopped.

➢ Systemic conditions with a higher risk of tendon rupture include diabetes, gout, rheumatoid arthritis, and chronic kidney disease.

➢ Certain drugs, such as corticosteroids and fluoroquinolones, have also been implicated in tendon ruptures.

➢ Patients with these systemic conditions who are taking statins in combination with other drugs that increase the risk of tendon injury should be educated about this risk and alternative treatments, including diet and exercise.
A Tale of Two Eastwoods: Iconographic Persona and Rhetorical Ethos in Clint Eastwood's “Halftime in America” and RNC 2012 Address
Authors: Schmitt Casey R.
Published: May 2016

In 2012, actor-director Clint Eastwood was twice the special focus of attention in America, not for his acting or directing accomplishments but for a pair of uniquely prominent and instantly memorable televised ideological statements. His scripted appearance in a two-minute Super Bowl XLVI halftime commercial for the Chrysler Group was widely lauded while his address to the Republican National Convention in Tampa, Florida, later that year remains to this day an object of pointed criticism and widespread ridicule. This essay uses side-by-side rhetorical analyses of the two examples - this tale of two Eastwoods - to demonstrate the import of expectation and rhetorical persona in an age of modern, national, and global celebrity. The comparison illustrates how a massively famous speaker whose mediated public image has achieved highly symbolically status may both benefit from and struggle with what I call “iconographic persona.” The essay argues that celebrity speakers and spokespersons in modern societies must seek congruence between iconographic persona and rhetorical ethos. In Eastwood's case, the expectations and associations met and solidified by the Chrysler ad went unmet in the RNC address, and thus two appeals by the same speaker resulted in two very different receptions. In conversation with Amossy, Halloran, and Butterworth in “connecting” contemporary discussions of rhetoric, celebrity, nationalism, and sport, this essay sheds light on the unique rhetorical position of the celebrity speaker in the political or activist spheres.
@IKnowTheseWords: A Twitterbot Textual Performance
Authors: Burrough Xtine
Published: May 2016

Twitterbots automate the process of tweeting. They proliferate the social network with messages crafted for hash tags, themes, or replies. @IKnowTheseWords is a bot that I created to assist me in automatically archiving my wordhord from the “OED Word of the Day” database as an online Twitter performance. As such, the bot is a helper-agent that serves words to my Twitter timeline, one day at a time. Consequently, it is essential that I talk back to the bot, letting it know (and anyone else who views these tweets and replies) which words should be included in my personal archive. This process will take years as the bot and I perform the tasks: Tweeting a word from the OED, sorting each word, and capturing those words that are part of my current vocabulary using a Twitter archiving Google spreadsheet. With two “I”s involved in the process of knowing—or not—these words, @IKnowTheseWords speaks predictably and intelligently as a bot and randomly, with culturally specific musings as the “I” who replies to each tweet. In this case study I arrive at a philosophical understanding of how the project made a theoretical pivot as a result of its current processing and performance with emerging media tools.
Creator’s Discussion of the Growing Focus on, and Potential of, Storytelling in Video Game Design
Authors: Haggis Mata
Published: May 2016

The video game industry, by its wider reputation, is not commonly regarded for its deep and thoughtful experiences. In its common media presence it is represented as frequently dealing with content that is excessively violent and usually expressing themes and genres that are otherworldly: science-fiction, horror, or fantasy. However, the broad reputation of video games’ reputation is not wholly deserved, partly due to an arthouse-esque movement growing rapidly alongside the larger, traditional releases. In the last decade, and five years especially, there have been an increasing number of games which tell personal stories that are either inspired by life or that are autobiographical and that defy that broader reputation. These games are often highly concerned with creating vivid and believable characters, telling personal stories, or conveying emotional experiences using interaction to enhance the narrative. This article discusses some of the key titles in this area, the debates in video game culture surrounding them, and some of the choices made in the development of the author's own narrative game experience 'Fragments of Him'.

Across the news and entertainment media there is an increasingly prevalent phenomenon: actors, performers and artists who play “versions of themselves”. This paper explores the entertaining and critical potentials of this strategy, which I term “parafictional personas”. I draw upon Carrie Lambert-Beatty’s theorisation of the parafictional as a critical mode that has developed out of (and in tension with) the “historiographic turn”. Parafictional personas are a specific iteration, characterised by two key components: they compulsively imbue every opportunity with layers of interconnections and self-reflexive moments; and they involve artists and performers appropriating their own “proper name”, constructing fictionalised doubles of themselves. While found widely across media, my central focus is contemporary visual art, analysing two key examples, Israeli–American artist Omer Fast and Lebanese artist Walid Raad.
These artists are significant because their personas are not simply means of performing themselves as individuals; they are integrated into the ways the artists approach contentious, still unfolding events of contemporary history. Parafictional personas have the potential to thoroughly embed fictional constructs within reality, because of the difficulties in separating elements represented by the same proper name. Their critical potential lies in the ways that they make visible the difficulties of maintaining clear distinctions between historical and fictional, social and individual narratives. Parafictional personas confound cultural desires to order, categorise and “make sense” of historical narratives. They reveal how much we as viewers (and societies) search for ideas of truth and resolution, even if such truths are presented as incomplete, questionable, or irresolvable.
Multiphase Rate-Transient Analysis in Unconventional Reservoirs: Theory and Application
Authors: Uzun Ilkay , Kurtoglu Basak , Kazemi Hossein

In unconventional reservoirs, production data are generally analyzed by use of rate-transient techniques derived from single-phase linear-flow models. Such linear-flow models use rate-normalized pressure, which is pressure drop divided by reservoir-flow rate vs. square root of time. In practice, the well-fluid production includes water, oil, and gas. The oil can be light oil, volatile oil, and gas/condensate as in the Bakken, Eagle Ford, and Barnett, respectively. Thus, single-phase analysis needs modification to account for production of fluid mixtures.

In this paper, we present a multiphase-pressure-diffusivity equation to analyze multiphase flow in single- and dual-porosity models of unconventional reservoirs. Our approach is similar to the work presented by Perrine (1956); however, our approach has a theoretical foundation, whereas Perrine (1956) used pragmatic engineering analogy for constant flow rate in vertical wells only. In addition to oil, gas, and formation brine, our method accounts for gas/condensate production, and the flowback of the injected hydraulic-fracturing fluids. Overall, our proposed approach is more comprehensive than the single-phase models but maintains the simplicity of the conventional methods.

Our paper includes diagnostic plots of rate-normalized well pressure for light oils and gas/condensates in unconventional reservoirs. Data from two Bakken and two Eagle Ford wells will be presented to demonstrate the usefulness of our approach. In addition to the mathematical analysis of flow-rate and pressure data, we will present the effect of well-stimulation and fluid-lift methods on the flow-rate characteristics of Bakken and Eagle Ford wells.
Application of recycled sludge to stabilize coagulation process
Authors: Gumińska Jolanta , Gumiński Adam
Published: May 2016

In conventional treatment of variable quality mountain water, an inability to immediately adjust the coagulant dose to variations in water quality causes overdose or underdose of coagulant in relation to its optimal value. The results of the research showed that the reuse of post-coagulation sludge was an effective method to maintain high and stable coagulation effectiveness under both polyaluminium chloride (PACl) overdose and underdose conditions. Recycled sludge contains a large portion of insoluble aluminium hydroxides that could be utilized in underdose PACl conditions. Post-coagulation sludge recycled to a flocculation tank enabled the reduction of a dose of low basicity PACl by 15% compared to a dose required in conventional coagulation. In periods of coagulant overdosing, sludge addition prevented an increase in the number of fine particles in an outflow from sedimentation tanks that could not be retained in a filter bed.
Improvement of multi-parameter-based feed-forward coagulant dosing control systems with feed-back functionalities
Authors: Liu W. , Ratnaweera H.
Published: May 2016

Coagulant dosing control in drinking and wastewater treatment plants (WWTPs) is often limited to flow proportional concepts. The advanced multi-parameter-based dosing control systems have significantly reduced coagulant consumption and improved outlet qualities. Due to the long retention time in separation stages, these models are mostly based on feed-forward (FF) models. This paper demonstrates the improvement of such models with feed-back (FB) concepts with simplifications, making it possible to use even in systems with long separation stages. Full-scale case studies from a drinking water treatment plant and a WWTP are presented. The model qualities were improved by the dosage adjustment of the FB model, ranging from 66% to 197% of the FF model. Hence, the outlet qualities became more stable and coagulant consumption was further reduced in the range of 3.7%–15.5%.
Modiﬁcation of waste coal gangue and its application in the removal of Mn2+ from aqueous solution
Authors: Qiu Ruifang , Cheng Fangqin
Published: May 2016

We developed a new calcination method to convert coal gangue (CG), a common waste generated from coal production process, into a modified form, which could be used as an adsorbent to remove Mn2+ from aqueous solution. Sodium tetraborate (Na2B4O7·10H2O) was added into the CG calcination process as an additive, and the concentrations of Na2B4O7·10H2O were optimized along with the calcination temperature to obtain the best adsorbent capacity of modified coal gangue (MCG). We applied multiple analytical methods such as scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy and Brunauer–Emmett–Teller analysis to characterize the MCG. The results showed it had a smaller particle size and a larger specific surface area and pore volume after modification. It also indicated that the phase of CG transformed from kaolinite to metakaolinite after calcination. Moreover, a new substance was generated with two new peaks at 1,632 cm−1 and 799 cm−1. The Mn2+ absorption capacity of MCG was evaluated using a series of experiments with different adsorbent doses, pH values and initial Mn2+ concentrations during the adsorption process. We found that Mn2+ adsorbent capacity of MCG increased by more than seven-fold compared to that of CG. The Langmuir isotherm model and the pseudo-second-order kinetic model provided the best fit to the adsorption processes.

The study investigated the pretreatment of real paracetamol (PCT) wastewater of a pharmaceutical industry by Fenton process. At the best experimental conditions (COD/H2O2 = 1/1, Fe+2/H2O2 = 1/70, settling method:centrifuging, pH 6 at settling step), 92.7, 92.7, 95.5, 99.1, 99.9 and 99.4% of chemical oxygen demand (COD), total organic carbon (TOC), 5-day biological oxygen demand (BOD5), PCT, para-amino phenol (PAP) and aniline were removed, respectively. Changes in the concentrations of these parameters were also investigated for both oxidation and settling steps of Fenton process. It was found that COD and TOC were removed at the settling step (precipitation) whereas PCT, PAP and aniline were removed at the oxidation step. Mass balance calculations were also studied to show the mass distributions of COD in different phases (gas + foam, effluent and sludge). Fenton process was found as an effective method for the pretreatment of real PCT wastewater for discharging in a determined collective treatment plant.
Recalling the Past

The present article investigates the concept of kurtijo, roughly ‘courtyard’,
‘home’, in Judeo-Spanish (known also as Ladino, Djudezmo or
Sephardi), the language of Sephardic Jews, currently under threat of
extinction (Harris 1994, 2011). It argues that after the Holocaust kurtijo
became a culturally salient word and it may be regarded as a cultural
key word in Ladino. Dictionaries and texts of contemporary
Ladino poets will be used as the main source of data. The meaning
of kurtijo will be expressed in the form of an NSM explication (Goddard
and Wierzbicka 2002, 2014).

The surfactant ligand 2,2′,2″-(dodecylammonio)triacetate (L) was synthesised and characterised. The kinetics of hydrolysis of bis(4-nitrophenyl) phosphate (BNPP) in the catalytic system containing the surfactant ligand and cobalt(II) were investigated. The analysis of specific absorption spectra of the hydrolytic reaction systems indicated that key intermediates made up of BNPP and the Co(II) complex are formed. Here, the proposed mechanism of BNPP catalytic hydrolysis is based on the analytical result of the specific absorption spectrum and the corresponding kinetic constants are calculated. The results show that the Co(II) complex as a hydrolase mimic exhibits good catalytic activity and similar catalytic character to the natural enzyme.

An efficient and green method for the synthesis of 1 H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives has been achieved through the one-pot, three-component condensation of aromatic aldehydes, malononitrile or ethyl cyanoacetate, and phthalhydrazide in the presence of 1-butyl-3-methyl imidazolium hydroxide ([bmim]OH) as catalyst in EtOH. This reaction does not involve any hazardous organic solvent and toxic catalyst. The ionic liquid can be recovered and recycled for subsequent reactions. Moreover, this protocol has the advantages of easy work-up, short reaction time, mild reaction conditions and environmentally benign procedures compared with the reported methods.
