Rheological investigation of creep recovery for UHMWPE or carbon nanotubes in isotactic polypropylene matrix
Authors: Xu Zhaohua , Li Heng , Sun Ning 
Published: December 2015

AbstractIsotactic polypropylene/ultrahigh-molecular-weight polyethylene blends (iPP/UHMWPE) and iPP/carbon nanotubes composites (iPP/CNTs) were prepared by a coagulation method followed by compression molding. The percolation thresholds for melts of iPP/UHMWPE blends and iPP/CNTs composites determined by rheometer, were beyond 5.0 wt% and close to 4.0 wt%, respectively. The creep and creep-recovery behavior of iPP/UHMWPE and iPP/CNTs melts were systematically investigated by rheological measurements. The results indicated that UHMWPE and CNTs played similar roles in the material’s elastic recovery, the addition of 2.0 wt% UHMWPE or 0.2 wt% CNTs increased the elastic recovery about 10 fold in comparison with neat iPP.
Signaling pathways regulating Homer1a expression: implications for antidepressant therapy
Authors: Serchov Tsvetan , Heumann Rolf , van Calker Dietrich , Biber Knut 
Published: December 2015

Abstract
Homer1a is upregulated by several different antidepressant measures, including non-pharmacological treatments, like sleep deprivation (SD) and electroconvulsive therapy (ECT) and antidepressant drugs, such as imipramine, fluoxetine and ketamine. Homer1a induction might thus be a crucial joint mechanism for antidepressant therapy in general. However, the upstream signaling pathways that regulate or induce Homer1a expression are still not well understood. The main focus of the present review is to offer an overview of the current knowledge about the potential role of Homer1a in depression and the signaling pathways responsible for Homer1a regulation. It is suggested here that a detailed characterization of the signaling mechanisms leading to Homer1a expression might provide novel therapeutic targets for antidepressant drug development.
Preparing for Death: Aspects of Continuity and Change in Swedish Late Medieval and Reformation Traditions
Authors: Sundmark Stina Fallberg 
Published: December 2015

Abstract
When a person in the parish was in bed seriously ill or was hovering between life and death, the priest would be called to him or her and it was part of the priest’s duty in the medieval and Reformation traditions to make his way to the sick or the dying whatever the weather or the state of the roads, a journey that could be both long and arduous. When the priest arrived at the sickbed, he could listen to confession and give communion and extreme unction. This article gives an overview over the ways in which the pastoral visits to the sick and the preparation for death should or could be carried out liturgically according to Swedish medieval and Reformation sources. Some central conceptions of dying are pointed out in the relevant liturgical parts, as well as their theological and pious explanations.
Parallel Multi-Class Contour Preserving Classification
Authors: Fuangkhon Piyabute 
Published: December 2015

AbstractSerial multi-class contour preserving classification can improve the representation of the contour of the data to improve the levels of classification accuracy for feed-forward neural network (FFNN). The algorithm synthesizes fundamental multi-class outpost vector (FMCOV) and additional multi-class outpost vector (AMCOV) at the decision boundary between consecutive classes of data to narrow the space of data. Both FMCOVs and AMCOVs will assist the FFNN to place the hyper-planes in such a way that can classify the data more accurately. However, the technique was designed to utilize only one processor. As a result, the execution time of the algorithm is significantly long. This article presents an improved version of the serial multi-class contour preserving classification that overcomes its time deficiency by utilizing thread-level parallelism to support parallel computing on multi-processor or multi-core system. The parallel algorithm distributes the data set and the processing of the FMCOV and AMCOV generators to be operated on available threads to increase the CPU utilization and the speedup factors of the FMCOV and AMCOV generators. The technique has been carefully designed to avoid data dependency issue. The experiments were conducted on both synthetic and real-world data sets. The experimental results confirm that the parallel multi-class contour preserving classification clearly outperforms the serial multi-class contour preserving classification in terms of CPU utilization and speedup factor.
Strengthening of Al and Al-Mg alloy wires by melt inoculation with Al/MgB2 nanocomposite
Authors: Florián-Algarín David , Marrero Raúl , Padilla Alexandra , Suárez Oscar Marcelo 
Published: December 2015

AbstractThis study hinges on the feasibility of strengthening Al and Al-Mg wires by adding Al nanocomposite pellets containing MgB2nanoparticles into the melt upon fabrication. These MgB2nanoparticles were obtained by fragmentation using a high-energy ball mill, and were, afterward, mechanically alloyed with pure aluminum. The resulting MgB2/Al nanocomposite pellets were sintered at 260°C to be subsequently added into molten aluminum and an Al-Mg alloy melt. Cold rolling intercalated with stepwise annealing allowed the fabrication of 1 mm diameter wires with a final area reduction of 96%. Mechanical and physical properties of the treated wire specimens were compared to those of similarly processed pure aluminum wire. The ultimate tensile strength of the treated wires increased approximately double fold with respect to untreated wires at the expense of some loss in electrical conductivity.
A variational material model for transformation-induced plasticity in polycrystalline steels
Authors: Waimann Johanna , Junker Philipp , Hackl Klaus 
Published: December 2015

AbstractThis work presents a variational material model for transformation-induced plasticity in steels. We will use the principle of the minimum of the dissipation potential to develop a coupled material model for plastic deformations and phase transformations that simultaneously accounts for the hardening effects that play an important role. We will use a polycrystalline approach and introduce a combined Voigt/Reuß bound and a coupled ansatz for the dissipation functional to model the simultaneous effects of plastic deformations and phase transformations. Finally, we will present the first numerical results for a tension/compression test.

Effect of filler type and composition on the mechanical, thermal, and dynamic mechanical properties of PS/SBR vulcanizate
Authors: Anjum Hirra , Ahmad Syed Waqas , Sharif Rabia , Tausif Muhammad 
Published: December 2015

Abstract
Dynamic vulcanization is an eminent industrial process to enhance the physical, thermal, and rheological properties of polymer composites. The present experimental study comprised the formation of polystyrene (PS) and styrene butadiene rubber (SBR) composites using three different types of fillers, namely, kaolin, talc, and rice husk powder (RHP), whereas dicumylperoxide was added as a cross-linking agent. Further, the filler loading was varied from 0 to 20 parts per hundred of resin (phr) for all types (i.e. RHP). The mechanical (i.e. tensile strength, elongation at break, and impact strength), thermal (i.e. melting point and softening point index), and dynamic mechanical properties of each composite were measured and compared with each other. The results indicate that kaolin-based vulcanizate showed better mechanical, thermal, and dynamic mechanical properties compared to that of talc and RHP vulcanizate. Furthermore, it can be observed that the mechanical, thermal, and dynamic mechanical properties of PS/SBR vulcanizates are the function of filler loadings for all three types of fillers (i.e. kaolin, talc, and RHP). In addition, high-temperature storage properties (i.e. loss modulus and storage modulus) were also investigated for better design and material optimization. The study may be helpful to the tribological applications in material selection and design.

Published: December 2015

Abstract
The effects of poly(d-lactide) (PDLA), nanoclay, talc, and stereocomplex formation were investigated in blends where these materials were added as a minor phase in a major phase of poly(l-lactide) (PLLA). Blends containing 2% PDLA, nanoclay, or talc as nucleants were prepared via melt blending and showed a strong increase in the crystallization rate as revealed by isothermal and nonisothermal crystallization measurements. The blending of 2% PDLA with PLLA led to the highest crystallization rate. Moreover, a stereocomplex formation was observed in a PLLA/PDLA blend (50:50). Wide-angle X-ray diffraction and differential scanning calorimetry verified that complete stereocomplex crystallites that do not form homocrystallites can be achieved. Compared with pure PLLA, the stereocomplex had a higher melting temperature and a higher crystallization temperature, by more than 50°C and 25°C, respectively.
An Empirical Bayes risk prediction model using multiple traits for sequencing data
Authors: Li Gengxin , Cui Yuehua , Zhao Hongyu 
Published: December 2015

AbstractThe rapidly developing sequencing technologies have led to improved disease risk prediction through identifying many novel genes. Many prediction methods have been proposed to use rich genomic information to predict binary disease outcomes. It is intuitive that these methods can be further improved by making efficient use of the rich information in measured quantitative traits that are correlated with binary outcomes. In this article, we propose a novel Empirical Bayes prediction model that uses information from both quantitative traits and binary disease status to improve risk prediction. Our method is built on a new statistic that better infers the gene effect on multiple traits, and it also enjoys the good theoretical properties. We then consider using sequencing data by combining information from multiple rare variants in individual genes to strengthen the signals of causal genetic effects. In simulation study, we find that our proposed Empirical Bayes approach is superior to other existing methods in terms of feature selection and risk prediction. We further evaluate the effectiveness of our proposed method through its application to the sequencing data provided by the Genetic Analysis Workshop 18.

Published: December 2015

Abstract
Magnesium acesulfamate, Mg(C4H4NO4S)2·6H2O, was prepared by the reaction of acesulfamic acid and magnesium carbonate in aqueous solution, and characterized by elemental analysis. Its crystal structure was determined by single crystal X-ray diffraction methods. The substance crystallizes in the triclinic space group P1̅ with one molecule per unit cell. The FTIR spectrum of the compound was also recorded and is briefly discussed. Some comparisons with other simple acesulfamate and saccharinate salts are also made.

Published: December 2015

BACKGROUND:
Hemolytic uremic syndrome associated with Shiga toxin–producing Escherichia coli (STEC-HUS) is a severe acute illness without specific treatment except supportive care; fluid management is concentrated on preventing fluid overload for patients, who are often oligoanuric. Hemoconcentration at onset is associated with more severe disease, but the benefits of volume expansion after hemolytic uremic syndrome (HUS) onset have not been explored.

METHODS:
All the children with STEC-HUS referred to our center between 2012 and 2014 received intravenous infusion targeted at inducing an early volume expansion (+10% of working weight) to restore circulating volume and reduce ischemic or hypoxic tissue damage. The short- and long-term outcomes of these patients were compared with those of 38 historical patients referred to our center during the years immediately before, when fluid intake was routinely restricted.

RESULTS:
Patients undergoing fluid infusion soon after diagnosis showed a mean increase in body weight of 12.5% (vs 0%), had significantly better short-term outcomes with a lower rate of central nervous system involvement (7.9% vs 23.7%, P = .06), had less need for renal replacement therapy (26.3% vs 57.9%, P = .01) or intensive care support (2.0 vs. 8.5 days, P = .02), and needed fewer days of hospitalization (9.0 vs 12.0 days, P = .03). Long-term outcomes were also significantly better in terms of renal and extrarenal sequelae (13.2% vs 39.5%, P = .01).

CONCLUSIONS:
Patients with STEC-HUS had great benefit from early volume expansion. It is speculated that early and generous fluid infusions can reduce thrombus formation and ischemic organ damage, thus having positive effects on both short- and long-term disease outcomes.
MoSi2-Based High-Temperature Structural Silicides
Authors: Petrovic John J. 
Published: December 2015

Structural materials that can withstand oxidizing and aggressive environments at temperatures above 1000°C constitute an enabling materials technology for a wide range of applications in the industrial, aerospace, and automotive arenas. A few of the industrial uses for such materials are furnace elements and components, power generation components, high-temperature heat exchangers, gas burners and igniters, and high-temperature filters. Aerospace applications include turbine aircraft engine hot-section components such as blades, vanes, combustors, nozzles, and seals. Automotive applications involve components such as turbocharger rotors, valves, glow plugs, and advanced turbine engine parts.There is increasing interest in silicide-based compounds for high-temperature structural uses under oxidizing conditions in the range of 1200–1600°C. In this temperature range, for oxidation and strength reasons, the choice of materials is limited to the silicon-based structural ceramics such as Si3N4 and SiC, and the new class of “high-temperature structural silicides.” An extensive survey of progress in the area of high-temperature structural silicides has recently been published.
Interfaces in Structural Ceramics
Authors: Norton M. Grant , Carter C. Barry 
Published: December 2015

Structural ceramics are necessarily polycrystalline and their usefulness is largely determined by the interfaces between the grains. The relationship between the structure and chemistry of different interfaces and the micro-structure can be illustrated by reviewing studies of interfaces in a wide range of materials including such classical ceramics as Al2O3, the current “hightech” polyphase ceramics exemplified by ZrO2-toughened Al2O3, and the composite materials of the future. Using transmission electron microscopy is essential for a complete understanding, but limitations to its use must be recognized. Only by understanding the factors that control the behavior of these interfaces will it become possible to further extend the application of interface engineering.Structural ceramics are a group of materials that can be used for applications requiring their strength to persist at high temperatures or in conditions that would be particularly corrosive to alternative materials, which are usually metallic. Strength and strength-related properties such as toughness depend largely on the microstructural features of the processed material.The microstructure is defined by the morphology and size of the grains and the interfaces between these grains. If the grains are in intimate contact, then the interface is a grain boundary of the type familiar from studies of metals.
Exploring Optimal Pronunciation Teaching: Integrating Instructional Software into Intermediate-level EFL Classes in China
Authors: Hanna Barbara Elizabeth , Gao Yang 
Published: December 2015

This study sought to investigate the effectiveness of teaching pronunciation with instructional software to a cohort of Chinese speakers of English aged from 13 to 16 with a lower-intermediate language proficiency level. It also attempted to explore the relationship between language learners’ attitudes towards pronunciation and their pronunciation learning. Sixty students at an English language school in China participated in this project: 20 were instructed by a teacher, another 20 used instructional software (New Oriental Pronunciation) alone, and the remaining 20 received combined instruction from both a teacher and the software. Participants’ performances on pronunciation were evaluated in a pre-test and post-test. Their attitudes towards pronunciation were also assessed, in pre- and post- surveys. In addition, an open-ended questionnaire collected students’ reflections on the software and the lead researcher took observation notes during instruction. The greatest increase in performance was achieved by students who had undergone both forms of instruction, suggesting that the combination is optimal. Participants whose attitudes towards pronunciation changed the most made the greatest improvement in pronunciation, indicating that attitudes are crucial to pronunciation learning. This study provides a number of recommendations for various fields including software design, teacher training, and future research.
Teologi Wirausaha
Authors: Jalil Abdul 
Published: December 2015

<p>In the social theory of religion, it is commonly believed that the inner aspect of man such as religious experience does have a role in shaping his outer, namely external dimension. How one behaves is a result of his/her inner state. One’s attitude is none other than the manifestation of his/her religiousness. On that basis, this paper argues that the spirit of entrepreneurship that one has within him/her is the result of his/her faith –and also understanding- of his/her religion. The paper holds that it is religion that drives one to be an entrepreneur. The Islamic world-view concerning the dynamics of life for instance, has been the major source of inspiration for many youngsters to do business. This paper therefore deals with some Islamic teachings concerning life such as worldly well-being, free will and the value of work before God. The paper however also discovers that although Islam has a lot to say concerning business, only few Muslims made use of its teaching do develop what can be called Islamic entrepreneurship. </p>
Isu Lingkungan dalam Perspektif Kalam, Fiqh, dan Tasawuf
Authors: Sukarni Sukarni 
Published: December 2015

There is no doubt that the problem of environment has become the most formidable issue faced by human being in the modern history. The danger imposed by the environmental crisis is much greater than the danger of any forms of war. This crisis has thus become the greatest enemy of humanity. The level and extent of the danger requires equally a great effort to address and tackle it. It is here that this paper tries to contribute. It attempts to offer an Islamic perspective of environment and its conservation. The paper is convinced that Islam is rich with perspectives on this issue. It therefore, introduces the many theories and views on environment that the sciences of Islam have spoken about. It brings into discussion the view of the science of theology (kalam), jurisprudence (fiqh) and sufism (tasawuf) on environment. Each of these sciences is discussed in relation to the others, as well as in the context of what the paper calls fiqh lingkungan (the jurisprudence of environment). The idea that underlines the paper is thatthese sciences are—generally speaking—concerned with the idea of personal and collective responsibility; an idea that already has a direct relevance to the problem of environment.
Kontribusi Imam al-Râfi‘î dan Imam al-Nawawî dalam Penataan Keragaman Pendapat Hukum Mazhab Shâfi‘î

The diversity of legal opinions in the Shâfi‘î school of thought (<em>madhhab</em>), in the form of old opinion (<em>qawl qadîm</em>) and new opinion (<em>qawl jadîd</em>) and the <em>ijtihâd</em> activities that pertained to some centuries after the passing away of al-Shâfi‘î, has brought this <em>madhhab</em><em> </em>into encounter with serious problems in selecting the law. In such a situation, al-Râfi‘î and al-Nawawî came into the fore as <em>muharrir</em> (selector) to cope with this uncertainty. This research tries to analyze all scientific activities of the two scholars using the theory of <em>tarjîh</em>. This research found out that they attempted to establish a legal certainty in the Shâfi‘î school of law through the making of new mixed system of <em>tarjîh</em> to ensure which opinions deserve to be regarded as valid from the viewpoint of Shâfi‘î <em>madhhab</em>. This achievement contributes to the enrichment of Shâfi‘î <em>madhhab</em> as a legal school consisting of a great variety of legal opinions that equips itself with procedures of selection used as norms of everyday life.
La migración femenina y los cambios en las relaciones de género en las familias: el caso de las transmigrantes colombianas en Italia
Authors: Ciurlo Alessandra 
Published: December 2015

En las migraciones internacionales, los movimientos poblaciones de mujeres son muy significativos, no solo por el número de personas que involucran, sino también porque presentan características propias que los distinguen de los movimientos poblacionales masculinos. La perspectiva de género aplicada a los fenómenos migratorios ha sido muy útil para demostrar que las migraciones no son neutrales en cuanto al sexo, y entender en profundidad las migraciones femeninas.Este artículo se focaliza en las migraciones colombianas hacia Italia, un fenómeno todavía poco estudiado pero que presenta particularidades interesantes por su fuerte heterogeneidad, por la elevada presencia femenina y la variedad de itinerarios de las mujeres migrantes. A partir de la perspectiva de género, pretende observar las diferencias entre la experiencia de hombres y mujeres durante la migración. Ello para desentrañar algunas de las desigualdades de género y su intersección con otras desigualdades que derivan de algunas categorías sociales que intervienen durante la migración.Se focaliza en la familia, un observatorio importante donde las relaciones de género se manifiestan con gran determinación, pero donde se suceden cambios a partir de la migración, que contribuyen a modificar la condición familiar y social de la mujer. En dichos flujos, aunque los cambios en las relaciones de género no apuntan hacia una sola dirección, se evidencian diferentes trayectorias de las mujeres en las que a menudo ellas son protagonistas activas, independientes y autónomas, logrando articular ventajas y desventajas presentes durante el proceso migratorio.
