Poeticizing the economy: The Corsican language in a nexus of pride and profit
Authors: Jaffe Alexandra 
Published: January 2019

AbstractThis article explores the carefully managed semiotic complex found in the Corsican village of Pigna with respect to the themes of pride and profit in the valuation of minority languages. This complex includes the careful coordination of color, graphics, the use of the Corsican language, as well as high-tech soundscaping of place through QR codes that tie specific locales to Corsican music and multilingual texts. This display, labeled the “poeticizing of the economy” by a key social actor, is directed both at the many tourists who visit the village as well as Corsican visitors and locals. It is linked to an effort to embed Corsican linguistic and musical heritage in new practices that both create place and integrate tradition and modernity. On the one hand, these practices can be linked to discourses of both “pride” and “profit” (Duchêne and Heller 2012) attested in many minority language contexts. On the other hand, I argue that the Pigna esthetic indexes a shift in the framework for cultural and linguistic revitalization from one that emphasizes a return to past native speaker communicative practice to one that focuses on the collective agency and identity associated with style and stylization and “transactional,” or situated authenticities.

Authors: Bas Erdal , Ozarslan Ramazan , Baleanu Dumitru 
Published: January 2019

AbstractIn this work, we bring a different approach for Sturm-Liouville problems having Bessel and hydrogen atom type and we provide a basis for direct and inverse problems. From this point of view, we find representations of solutions and asymptotic expansions for eigenfunctions. Furthermore, some numerical estimations are given to illustrate the necessity of the Sturm-Liouville difference equations with the potential function for the convenience to the spectral theory. The behavior of eigenfunctions for the Sturm-Liouville problem having Bessel and hydrogen atom potential type is analyzed and compared to each other. And then, comparisons are showed by tables and figures.

Published: January 2019

Abstract
We have employed the exp(-φ(ξ))-expansion method to derive traveling waves solutions of breaking solition (BS), Zakharov-Kuznetsov-Burgers (ZKB), Ablowitz-Kaup-Newell-Segur (AKNS) water wave, Unstable nonlinear Schrödinger (UNLS) and Dodd-Bullough-Mikhailov (DBM) equations. These models have valuable applications in mathematical physics. The results of the constructed model, along with some graphical representations provide the basic knowlegde about these models. The derived results have various applications in applied science.
Thermo-convective instability in a rotating ferromagnetic fluid layer with temperature modulation
Authors: Sibanda Precious , Adam Ibrahim Noreldin Osman 
Published: January 2019

Abstract
We study the thermoconvective instability in a rotating ferromagnetic fluid confined between two parallel infinite plates with temperature modulation at the boundaries. We use weakly nonlinear stability theory to analyze the stationary convection in terms of critical Rayleigh numbers. The influence of parameters such as the Taylor number, the ratio of the magnetic force to the buoyancy force and the magnetization on the flow behaviour and structure are investigated. The heat transfer coefficient is analyzed for both the in-phase and the out-of-phase modulations. A truncated Fourier series is used to obtain a set of ordinary differential equations for the time evolution of the amplitude of convection for the ferromagnetic fluid flow. The system of differential equations is solved using a recent multi-domain spectral collocation method that has not been fully tested on such systems before. The solutions sets are presented as sets of trajectories in the phase plane. For some supercritical values of the Rayleigh number, spiralling trajectories that transition to chaotic solutions are obtained. Additional results are presented in terms of streamlines and isotherms for various Rayleigh numbers.
No evidence for airborne transmission of Toxoplasma gondii in a very high prevalence area in Lancaster County

Published: January 2019

AbstractBackground: Toxoplasma gondii (T. gondii) has been associated with acute food-borne illness, chronic low-grade inflammation, neuropsychiatric conditions and reactivation of chronic latent infection in immunocompetent hosts. Primary infection with T. gondii in pregnant women can lead to congenital toxoplasmosis. In addition to well-known oral tissue-cyst or oocyst ingestion, we hypothesized that the very high prevalence of T. gondii in certain populations exposed to agricultural dust could be, in part, a consequence of airborne infection with oocysts. Methods: We collected environmental dust samples from an area with a reportedly high T. gondii seroprevalence in the Old Order Amish population, in Lancaster, Pennsylvania. Samples included: a) air filters from air-conditioning units; b) swabs of settled dust; and c) vacuum filters containing airborne field dust. Pools of the swabs and shredded sub-samples of the air filters were fed to pigs, with inoculation into mice of heart tissue from seroconverted pigs. We also investigated the presence of T. gondii DNA using PCR amplification. Results: Only one pig seroconverted. However, bioassay of pig heart tissue further inoculated into mice showed no evidence of T. gondii infection. Consistently, no evidence of T. gondii DNA was revealed in any sample. Conclusions: No evidence of airborne transmission was found in the environmental samples that were examined.
Spirituelle und sakrale Räume
Authors: Kopp Stefan 
Published: January 2019

Zusammenfassung
Als spirituelle und sakrale Räume können mit einem anthropologisch erweiterten Raumbegriff neben den neueren Räumen der Stille und Andachtsräumen bzw. den klassischen Kirchen- und Kapellenräumen auch „heilige Räume“ der Spiritualität und der Liturgie bezeichnet werden. Im Kontext von Spiritual Care können sie der Spiritualität kranker Menschen und derer, die sie pflegen, Raum geben sowie als sinnstiftend und heilsam erfahren werden. Dabei geht es um die Frage, was Menschen hilft, eine Offenheit für Transzendenz zu finden und die liebende Zuwendung Gottes zu erfahren.
Heilende Räume: Diakonische (Ein)Richtung für Spiritual Care
Authors: Sigrist Christoph 
Published: January 2019

Zusammenfassung
Raumerfahrungen bilden die Basis für jede Form von identitätsstiftenden Beziehungen. Räume können dabei insbesondere neben spirituellen auch diakonische Dimensionen entfalten. Der Autor untersucht die Bedeutung von „Heilenden Räumen“ für Spiritual Care aus der Perspektive von Palliative Care, der Diakonie als helfendem Handeln sowie auf der Basis raumsoziologischer Studien seit Foucault.
Unterstützung von Spiritual Care durch räumliche Gestaltung von Gesundheitsbauten
Authors: Brichetti Katharina 
Published: January 2019

Zusammenfassung
Die räumliche Gestaltung von Gesundheitsbauten kann spirituelle Bedürfnisse und Spiritual Care behindern oder begünstigen. Patienten, Besucher und Personal erleben beispielsweise den Charakter eines Krankenzimmers als oft durchaus eindringliche Anmutungen und Stimmungen, sogenannte Atmosphären. Solches Erleben ist leiblich-räumlich. Ebenso ist es vieldimensional synästhetisch, integriert alle Sinne sowie Sinne und Geist.
Der Ausdruck „Synästhesie“ wird hier bewusst liberal in einer informellen und tendenziell weiten Bedeutung verstanden. Diese entspricht einer in vielen Kontexten etablierten und nach meinem Dafürhalten sachdienlichen Verwendung, auch wenn die originale sinnesphysiologische Definition dabei gelockert, erweitert und teilweise umgedeutet erscheint.
Der ganze Mensch ist davon betroffen und berührt, wie die Umgebung gestaltet ist, als Patient oft auf besonders intensive Weise. Doch wie lassen sich Räume so gestalten, dass ihre Grundstimmung spirituelle Bedürfnisse und Spiritual Care unterstützt? Inspiration läßt sich aus Erkenntnissen zum Welt-Erleben von Patienten, aus Ansätzen der „Healing Architecture“ und aus der Gestaltung sakraler Bauten und Räume gewinnen.
Spirituelle Räume
Authors: Wüthrich Matthias D. 
Published: January 2019

Zusammenfassung
Schwerstkranke, sterbende Menschen verbringen die letzte Phase ihres Lebens oft nicht in ihren vertrauten Wohnräumen, sondern müssen in fremde Räume wechseln. Welchen Einfluss kann Spiritual Care auf das „Raum-Erleben“ bzw. die räumliche Erfahrung dieser Menschen ausüben? Der vorliegende Artikel gibt auf diese Frage keine unmittelbare Antwort. Er leistet aber insofern einen Beitrag zu ihrer Beantwortung, als er raumtheoretisch darüber nachdenkt, wie das „Raum-Erleben“ von schwerstkranken, sterbenden Menschen im Kontext von Spiritual Care angemessen beschrieben und erfahrungsnah erfasst werden kann. Dazu wird das raumtheoretische Konzept eines interpersonalen Raumes entwickelt, der schließlich auch in seiner spirituellen Dimension dargelegt wird.
Analysis for Various Effects of Relaxation Time and Wall Properties on Compressible Maxwellian Peristaltic Slip Flow
Authors: Eldesoky Islam M. , Abumandour Ramzy M. , Abdelwahab Essam T. 
Published: January 2019

Abstract
The present study is related to indicating the several effects of the relaxation time, dynamic behaviour of wall properties and slip conditions at the boundaries on the peristaltic locomotion of viscous non-Newtonian Maxwell fluid flow through a two-dimensional (2D) horizontal flexible sinusoidal wave-shaped channel. An approximated theoretical model is constructed. The solution of the governing equations is developed using the perturbation method. Small amplitude ratio “ratio between amplitude of the wave and half channel width” for the wavy transport is considered for describing the velocity and pressure distributions. Different factors of wall features such as damping force coefficient, wall tension parameter, wall bending coefficient and spring stiffness factor in addition to various flow parameters such as the compressibility factor, Reynolds number, slip coefficient and also the main parameter of interest relaxation time are involved in the mathematical calculations and discussed through graphical representation. Graphs for mean axial velocity, perturbation function and velocity at the wall distributions using the previous coefficients are plotted and then discussed in detail. Results indicate that wall properties, compressibility factor and relaxation time in the presence of peristaltic transport have a significant effect on velocity distributions. The damping factor, wall tension, slip parameter and relaxation time are reducing the mean axial velocity and raising the reversal flow but, the wall elasticity factor enhances the mean axial velocity. Also, the liquid compressibility has a strong effect on the dynamics of the flow.
Melt Elongation Flow Behavior of Low-Density Polyethylene Composites Filled with Nanoscale Zinc Oxide
Authors: Liang Ji Zhao 
Published: January 2019

Abstract
The melt elongation flow properties of low-density polyethylene/nanoscale zinc oxide (nano-ZnO) composites were studied using a Rheotens rheometer (Göttfert Werkstoff-Prüfmaschinen GmbH, Buchen, Germany). The die extrusion rate varied from 9 to 36 mm/s, the temperature ranged from 160°C to 200°C, and the nano-ZnO weight fraction range was from 0.2 to 4 weight percent (wt.%). The results showed that the melt elongation stress increased with the increasing elongation strain rate; the melt elongation viscosity decreased with the increasing temperature, and the temperature dependence obeyed the Arrhenius equation. The melt elongation viscosity of the composites with 0.4–0.8 wt.% nano-ZnO was lower in the whole composite system. Moreover, the melt elongation viscosity increased when the elongation strain rate was lower than 0.3 s−1 and then decreased with the increasing elongation strain rate; the melt elongation viscosity reached a maximum at an elongation strain rate around 0.3 s−1 and presented the stress hardening phenomenon.

Published: January 2019

El algodón es la fibra natural de mayor importancia en el sector textil y representa unos de los productos básicos en la economía de más de 100 países, con un aproximado de 150 países que exportan o importan esta materia prima [7]. Su cultivo se considera como uno de los más intensivos, puesto que requiere grandes cantidades de agua, pesticidas y fertilizantes, lo que implica que los impactos ambientales sean mayores (Daño a la Salud Humana, Daño a los Ecosistemas y Daño a la disponibilidad de recursos); también se contempla los impactos que se generan en el proceso de la producción de la tela de algodón. Para la minimización de impactos generados en la cadena productiva se hace uso de la aplicación del análisis del ciclo de vida consecuencial al proceso de cuna a puerta, usando el software Umberto NTX LCA y la metodología ReCiPe a partir de información secundaria. Disponibilidad de recursos fue la categoría que mostraba mayores impactos en el proceso (212,14 puntos) y calidad de ecosistema, 127,84 puntos como categoría de menor impacto. Con las mejoras realizadas al proceso se tiene una reducción de 53,01 puntos.

Published: January 2019

Background and aimsDespite increases in female gambling, little research investigates female-specific factors affecting gambling behavior (GB). Although research suggests that some addictive behaviors may fluctuate across menstrual cycle phase (MCP), gambling requires further investigation. In two studies, we examined associations between MCP and three risky GBs: time spent gambling, money spent gambling, and the probability of consuming alcohol while gambling. Associations between MCP and negative affect were also examined in Study 2. We predicted that, consistent with self-medication theory, increases in negative affect (Study 2) and risky GBs (Studies 1 and 2) would occur premenstrually/menstrually relative to other phases.MethodsData were obtained from 33 female gamblers using a retrospective timeline followback procedure (Study 1) and from 20 female gamblers using a prospective 32-day, daily diary method (Study 2). In Study 2, salivary progesterone levels verified self-reported MCP validity.ResultsFindings revealed significant, but somewhat inconsistent, MCP effects on GBs across studies. The self-medication hypothesis was partially supported. Increases relative to another MCP(s) were found for alcohol consumption while gambling premenstrually, time spent gambling menstrually/premenstrually, money spent gambling menstrually, and negative affect premenstrually. Unexpectedly, findings more consistently indicated that GBs increased during ovulation, suggestive of enhanced reward sensitivity. Progesterone assays validated self-reported MCP (Study 2).Discussion and conclusionsThe results suggest a role of ovarian hormones on negative affect and GBs in females. This research could lead to the identification of female-specific factors affecting gambling and the development of more effective interventions for females with, or at risk for, problematic gambling.

Published: January 2019

Abstract

Poorly differentiated gastroenteropancreatic neuroendocrine carcinomas (GEPNECs) are a rare neoplasm with a bleak prognosis. Currently there are little prospective data available for optimal treatment. This review discusses the current available regimens and the future direction for the treatment of GEPNECs. Treatment plans for GEPNECs are often adapted from those devised for small cell lung cancer; however, differences in these malignancies exist, and GEPNECs require their own treatment paradigms. As such, current first-line treatment for GEPNECs is platinum-based chemotherapy with etoposide. Studies show that response rate and overall survival remain comparable between cisplatin and carboplatin versus etoposide and irinotecan; however, prognosis remains poor, and more efficacious therapy is needed to treat this malignancy. Additional first-line and second-line treatment options beyond platinum-based chemotherapy have also been investigated and may offer further treatment options, but again with suboptimal outcomes. Recent U.S. Food and Drug Administration approval of peptide receptor radionuclide therapy in low- and intermediate-grade neuroendocrine tumors may open the door for further research in its usefulness in GEPNECs. Additionally, the availability of checkpoint inhibitors lends promise to the treatment of GEPNECs. This review highlights the lack of large, prospective studies that focus on the treatment of GEPNECs. There is a need for randomized control trials to elucidate optimal treatment regimens specific to this malignancy.
Simulation of water dissipation in urban buildings
Authors: Zhou Jinjun , Liu Jiahong , Wang Hao , Wang Zhongjing 
Published: January 2019

Building water dissipation (BWD) refers to the change of water into vapour during water use activities in the building. The intention of the work described in this paper was to explore the BWD mechanism and establish a calculation model for BWD. The main research methods included experimental monitoring, a questionnaire survey and data mining. The results of this work showed that the capacity of buildings and the building area determine the type of water dissipation whereas the building population determines the BWD volume. The BWD calculation model was thus built based on two key parameters – building area and building population. Multi-variate regression fitting was used to analyse and study the other factors that influence BWD, such as water consumption, number of floors and so on. Using cluster analysis, 100 sample buildings were divided into different categories. Ordinary least squares regression was used to fit the multi-variate regression for the BWD of sample buildings. The results showed that the classification of buildings by cluster analysis can enhance the fitting effect of multi-variate regression of BWD.
New Insights into the Mechanism of NO3 - Selectivity in the Human Kidney Chloride Channel ClC-Ka and the CLC Protein Family
Authors: Lagostena Laura , Zifarelli Giovanni , Picollo Alessandra 
Published: January 2019

Significance Statement
The human chloride channels ClC-Ka and ClC-Kb, in complex with their accessory subunit barttin, are essential for NaCl reabsorption in the nephron. Mutations of ClC-Ka, ClC-Kb, or barttin cause type III and IV Bartter syndrome, characterized by renal salt wasting, hypokalemic metabolic alkalosis, and other effects. Using electrophysiologic techniques and mutational analysis, the authors show that the mechanism of discriminating Cl− versus NO3
− anions in the human ClC-Ka channel is unique in the CLC protein family, and they identified previously unimplicated residues as responsible for anion selectivity. This represents significant progress in better understanding of the relationship between structure and function of kidney channels ClC-Ka and ClC-Kb and of CLC proteins in general.

Background
The mechanism of anion selectivity in the human kidney chloride channels ClC-Ka and ClC-Kb is unknown. However, it has been thought to be very similar to that of other channels and antiporters of the CLC protein family, and to rely on anions interacting with a conserved Ser residue (Sercen) at the center of three anion binding sites in the permeation pathway Scen. In both CLC channels and antiporters, mutations of Sercen alter the anion selectivity. Structurally, the side chain of Sercen of CLC channels and antiporters typically projects into the pore and coordinates the anion bound at Scen.

Methods
To investigate the role of several residues in anion selectivity of ClC-Ka, we created mutations that resulted in amino acid substitutions in these residues. We also used electrophysiologic techniques to assess the properties of the mutants.

Results
Mutations in ClC-Ka that change Sercen to Gly, Pro, or Thr have only minor effects on anion selectivity, whereas the mutations in residues Y425A, F519A, and Y520A increase the NO3
−/Cl− permeability ratio, with Y425A having a particularly strong effect.

Conclusion
s ClC-Ka’s mechanism of anion selectivity is largely independent of Sercen, and it is therefore unique in the CLC protein family. We identified the residue Y425 in ClC-Ka—and the corresponding residue (A417) in the chloride channel ClC-0—as residues that contribute to NO3
− discrimination in these channels. This work provides important and timely insight into the relationship between structure and function for the kidney chloride channels ClC-Ka and ClC-Kb, and for CLC proteins in general.
