Authors: Akgün H. , Türkmenoğlu A.G. , Met İ. , Yal G.P. , Koçkar M.K. 
Published: December 2017

AbstractBecause of the current need for new landfill sites in Ankara, the suitability of Ankara Clay as a liner material for landfill sites was investigated. A mineralogical and geotechnical database was created by compiling the results of previous tests by the present authors as well as those of tests performed in the present study. The mineralogical properties of the samples were investigated by X-ray diffraction, scanning electron microscopy and methylene blue adsorption. The cation exchange capacities (CEC) of the samples vary from 12 to 35 meq/100 g soil and the dominant clay minerals are illite, smectite and kaolinite. The geotechnical properties of the Ankara Clay samples that were assessed included specific gravity, the Atterberg limits (plastic limit, liquid limit, plasticity index), particle-size distribution, compaction properties (i.e.maximum dry density and optimum water content) and hydraulic conductivity. Because the hydraulic conductivity of the samples was lower than the acceptable limit of 1 × 10−9 m/s, it follows that, from a geotechnical perspective, Ankara Clay is a suitable material for use as a compacted clay landfill liner. The relationships between the mineralogical and geotechnical parameters that were investigated by regression analysis indicated that the hydraulic conductivity of the compacted soil samples decreased with increasing plasticity index, clay content, CEC, smectite content, smectite to illite ratio and decreasing illite content. According to the specifications for field construction of compacted clay liners, Ankara Clay is suitable for compaction in the field.

Analysis of mutations causing nonclassical FD defined the hepcidin-binding site in the central cavity of Fpn. Hepcidin inhibits iron export through Fpn not only by causing Fpn endocytosis, but also by occluding the transporter.
Chiapas y los cambios espaciales de la migración a Estados Unidos en la vuelta de siglo
Authors: Castillo Guillermo , González Jorge 
Published: December 2017

En el marco de los cambios de la migración México Estados Unidos (EU) debido a las reformas económicas estructurales –el libre mercado, la desregulación y el adelgazamiento del estado, así como el Tratado de Libre Comercio de América del Norte (TLCAN)- y en el contexto del cambio de siglo (1990-2007), este artículo muestra cómo cambiaron y se dispersaron espacialmente los lugares de origen de los flujos migratorios mexicanos al país vecino del norte, pasando de estar concentrados en un conjunto de entidades federativas –en el centro occidente del país- a redistribuirse/expandirse a todo México, especialmente a un grupo emergente de estados –en el sureste del país-; en particular y como reflejo de esta tendencia, se analiza en detalle el cambio de flujos migratorios en Chiapas. Con base en diversas fuentes gubernamentales y de varios documentos de centros de investigación -censos, informes, estadísticas e índices-, este trabajo describe, a través de un análisis doble –a nivel de lo acontecido en el país y en una entidad federativa en específico-, una nueva geografía de la migración a inicios del presente siglo, con especial énfasis en Chiapas. Este artículo argumenta que estos cambios en esta migración –y para este periodo específico- están relacionados, no sólo con la demanda de trabajadores y la incorporación de mano de obra en el país de destino en diversos nichos laborales, sino también y fuertemente con la acentuación de una serie de procesos de reestructuración político-económica y de crisis en el país de origen.
Giuseppe Campos Venuti en el urbanismo italiano del siglo XX y los desafíos “de austeridad” para el futuro
Authors: Camerin Federico 
Published: December 2017

El tema que aborda este trabajo es la evolución de las nociones y conceptos de una figura clave del urbanismo italiano en el período posterior a la segunda guerra mundial, Giuseppe Campos Venuti. El objetivo es poner en evidencia las ideas y convicciones del urbanista italiano, su herencia y un pensamiento que se refleja en el análisis y la evolución de los contenidos del plan general de ordenación urbana italiano y cómo evoluciona el desarrollo urbano y territorial en el país.Se analiza el pensamiento de Campos Venuti a partir de los años sesenta del siglo XX y la modalidad de estudiar el urbanismo, enfocando la atención en el papel que el régimen inmobiliario capitalista tuvo en la actuación del plan del urbanismo “tradicional” y el contraste con el modelo que Campos Venuti propuso para ofrecer una alternativa urbanística a la práctica tradicional, es decir la auspiciada política de “austeridad” que conlleva las llamadas cinco “salvaguardias”. En los años noventa Federico Oliva se enlaza a las ideas de Campos Venuti, otorgando continuidad y evolución a la manera de estudiar el urbanismo: eso llevó a desdoblar del plan del urbanismo italiano en dos instrumentos: el plan estructural y el plan operativo.En síntesis, el pensamiento de Campos Venuti es fundamental para entender la situación actual del urbanismo y, en general, de la sociedad italiana: la relevancia y coherencia de sus aportaciones intelectuales todavía hoy son válidas en el contexto de crisis que actualmente sacude al sistema capitalista de los países europeos.
Modeling and reliability analysis of three phase z-source AC-AC converter
Authors: Prasad Hanuman , Maity Tanmoy 
Published: December 2017

Abstract
This paper presents the small signal modeling using the state space averaging technique and reliability analysis of a three-phase z-source ac-ac converter. By controlling the shoot-through duty ratio, it can operate in buck-boost mode and maintain desired output voltage during voltage sag and surge condition. It has faster dynamic response and higher efficiency as compared to the traditional voltage regulator. Small signal analysis derives different control transfer functions and this leads to design a suitable controller for a closed loop system during supply voltage variation. The closed loop system of the converter with a PID controller eliminates the transients in output voltage and provides steady state regulated output. The proposed model designed in the RT-LAB and executed in a field programming gate array (FPGA)-based real-time digital simulator at a fixedtime step of 10 μs and a constant switching frequency of 10 kHz. The simulator was developed using very high speed integrated circuit hardware description language (VHDL), making it versatile and moveable. Hardware-in-the-loop (HIL) simulation results are presented to justify the MATLAB simulation results during supply voltage variation of the three phase z-source ac-ac converter. The reliability analysis has been applied to the converter to find out the failure rate of its different components.
Improvement of Energy Efficiency and Environmental Safety of Thermal Energy Through the Implementation of Contact Energy Exchange Processes
Authors: Varlamov Gennadii Borysovich , Romanova Kateryna Alexandrovna , Nazarova Iryna , Daschenko Olga , Kapustiansky Andry 
Published: December 2017

Abstract
Energy efficiency improvement and ecological safety of heat power plants are urgent problems, which require scientifically grounded approaches and solutions. These problems can be solved partly within the presented heat-and-power cycles by including contact energy exchange equipment in the circuits of existing installations. A significant positive effect is obtained in the contact energy exchange installations, such as gas-steam installation ‘Aquarius’ and the contact hydrogen heat generator that also can use hydrogen as a fuel. In these plants, the efficiency increases approximately by 10-12% in comparison with traditional installations, and the concentration of toxic substances, such as nitrogen oxides and carbon monoxide in flue gas can be reduced to 30 mg/m3 and to 5 mg/m3, respectively. Moreover, the plants additionally ‘generate’ the clean water, which can be used for technical purposes.
Shame and Honor: Aristotle’s Thumos as a Basic Desire
Authors: Saenz Victor 
Published: December 2017

AbstractOne of three basic types of desire, claims Aristotle, isthumos(‘spirit,’ ‘passion,’ ‘heart,’ ‘anger,’ ‘impulse’). The other two areepithumia(‘appetite’) andboulêsis(‘wish,’ ‘rational desire’). Yet, he never gives us an account ofthumos; it has also received relatively little scholarly attention. I argue thatthumoshas two key features. First, it is able to cognize what I call ‘social value,’ the agent’s own perceived standing relative to others in a certain domain. In human animals, shame and honor are especially important manifestations of social value. Second,thumosprovides non-rational motivation to pursue what affirms the agent’s social value and avoid what denies it. Interpretations that holdthumosjust is anger, or that its object is the fine (kalon), I argue, are mistaken. My account also explains the role ofthumosin moral education. In a virtuous agentthumoswill be affectively attuned to the correct social rankings; it will take the practically wise, the lovers of the fine, or moral exemplars, as authorities.

In this way, the discrete solution can be shown to converge of second order in the

The effects of Curcuma longa and curcumin on reproductive systems
Authors: Mohebbati R. , Anaeigoudari A. , Khazdair M.R. 
Published: December 2017

Abstract
Objective. Curcuma longa (C. longa) was used in some countries such as China and India for various medicinal purposes. Curcumin, the active component of C. longa, is commonly used as a coloring agent in foods, drugs, and cosmetics. C. longa and curcumin have been known to act as antioxidant, anti-inflammatory, anti-mutagen, and anti-carcinogenic agents. Th e attempt of the present review was to give an effort on a detailed literature survey concentrated on the protective effects of C. longa and curcumin on the reproductive organs activity. Methods. The databases such as, PubMed, Web of Science, Google Scholar, Scopus, and Iran- Medex, were considered. The search terms were “testis” or “ovary” and “Curcuma longa”, “curcumin”, “antioxidant effect”, “anti-inflammatory effect” and “anti-cancer effect”. Results. C. longa and curcumin inhibited the production of the tumor necrosis factor-α (TNF-α) and prostaglandin E2 (PGE2) and increased the caspases (3, 8 and 9) activities in HL-60 prostate cancer. Furthermore, C. longa and curcumin suppressed the vascular endothelial growth factor (VEGF), phosphorylated signal transducers and activators of the transcription 3 (STAT) and matrix metalloproteinase-9 (MMP-9) in ovarian cancer cell line. Conclusion. C. longa and curcumin might decrease the risk of cancer and other malignant diseases in the reproductive system. C. longa and curcumin have a protective effect on the reproductive organs activity such as, anti-inflammatory, anti-apoptotic, and antioxidant effects in normal cells but showed pro-apoptotic effects in the malignant cells. Therefore, different effects of C. longa and curcumin are dependent on the doses and the type of cells used in various models studied.
Optimising resourcing skills to develop phraseological competence in legal translation: tasks and approaches
Authors: Huertas Barros Elsa , Buendía Castro Míriam 
Published: December 2017

Abstract
Based on a previous case study on common translation errors made by trainee translators when dealing with phraseological units in legal translation (Huertas Barros and Buendía Castro 2018, Analysing phraseological units in legal translation: Evaluation of translation errors for the English-Spanish language pair. In S. Gozdz Roszkowski & G. Pontrandolfo (eds.), Phraseology in legal and institutional settings: A corpus-based interdisciplinary perspective (Law, Language and Communication). London & New York: Routledge), this paper proposes some activities and approaches to minimise these errors and hence enhance students’ phraseological competence in this field. To this end, the authors first provide a description of the most representative legal resources available for translators, particularly for the English-Spanish language pair. This is followed by a review of approaches that could develop students’ legal translation competence, particularly phraseological competence. For each type of error identified in the previous case study, the authors propose a set of research-based activities which could prevent such errors by maximising the use of legal resources. The emphasis is put on preliminary documentary research and effective use of corpora prior to the translation task. The authors propose an integrated approach combining task-based approaches with approaches based on critical discourse analysis, problem-solving and decision-making. While these tasks have been designed for a semi-specialised legal text pertaining to a subdomain of family law (i.e. adoption), they can be easily applied to any other subdomains of legal translation.

The Normativity of Prudence
Authors: Kohl Markus 
Published: December 2017

Abstract:Kant’s account of “precepts of prudence” raises a striking interpretive puzzle. On the one hand, he presents such precepts as normative-practical rules; on the other hand, he relegates them to theoretical philosophy. I argue that to render these two strands coherent, we must assume that our empirical nature is a “source of normativity” for us: prudence is normative for us just because we have an “unconditional” empirical desire for obtaining happiness, a maximum of pleasant sensations. Since rules of prudence cognize the means for causing a state of affairs that we desire and value insofar as we are receptive natural beings, these rules do not presuppose the active self-legislation of practical reason. Hence they belong to the theoretical cognition of nature.
The Analytic Proposition Underlying Kantian Hypothetical Imperatives
Authors: Newton Alexandra 
Published: December 2017

Abstract:Kant maintains that it is easy to see how hypothetical imperatives are possible, because the following proposition is analytic: “Whoever wills the end also wills (in so far as reason has decisive influence on his actions) the indispensably necessary means to it that is within his control” (GMS, AA 04: 417). I distinguish three readings of the analytic proposition, which correspond to three ways of understanding how it reveals hypothetical imperatives to be possible. The first reads it as a theoretical proposition about constitutive features of an ideal agent. I argue that this fails to do justice to the first-personal character of the analytic proposition, as a proposition about the general practical concept ‘I will’ (or more generally, ‘I intend’). The second reading extracts actual imperatives from the concept of ‘willing an end’ by means of analysis. Against this, I argue that the derivation of an imperative from an act of willing an end is an act of synthesis, and that analysis of the concept of ‘my willing an end’ merely yields the

The co-variation of phonology with morphology and syntax: A hopeful history
Authors: Plank Frans 
Published: December 2017

AbstractThroughout its history, the hope has always been cherished that typology is holistic, and holism entails that there is systematic co-variation not only within levels or modules of grammar but also between them. Accordingly, numerous claims have been made that phonology does not vary across languages independently of morphology and syntax, and vice versa. The variables that are allegedly interrelated pertain to segment inventories, the shapes of syllables, morphemes, and words, phonological or morphonological rules, tones and accents, and rhythmic or prosodic patterns on the one hand and to analytic or (poly-)synthetic grammar, Separatist or cumulative morphological exponence, the complexity of grammatical units, and their linear order on the other. These claims are cataloguedin thispaper. To substantiate them and to accommodate those that are found valid in theories of the Interface between phonology, morphology, and syntax remain äs tasks for the future.
Performing the Self in the Mainstream
Authors: Dmitrow-Devold Karolina 
Published: December 2017

AbstractBlogging has become an integral part of girls’ media culture in Norway. This article investigates how teenage girls in the mainstream blogging community perform selves in their blogs over time. While studies of girls’ self-presentations online abound, most draw solely on analyses of online artefacts and lack a temporal perspective. To address these gaps, this investigation has employed a longitudinal design combining in-depth interviews with ethnographic content analyses of blogs, and has analysed girls’ online-based performances of self as integral to their offline experiences framed by the wider cultural context and gendered discourses. This approach is fruitful because it acknowledges girls’ changing experiences across time and contexts, thus making possible a contribution to the theorization of identity as performed across the online and the offline settings and interactions in an ongoing process.
Analysis of Individual Aspects Influencing Non-purchasing in an Online Environment and Consumer Willingness to Purchase Custom-Made Apparel
Authors: Žuraj Milica , Šparl Petra , Žnidaršič Anja 
Published: December 2017

Abstract

Purpose: The main purpose of the study was to assess the opinion of online consumers about the possibility of making custom apparel using 3D body scanning technology in an online environment and to investigate the shopping experience of consumers who purchase in the online apparel market. In order to be able to propose solutions to improve the online shopping experience, we also investigated aspects influencing non-purchasing in an online environment.

Methods: An online questionnaire on shopping experience, influences on the purchase, and the process of online apparel shopping using advanced technology was prepared and distributed via several online channels to the consumers who purchase apparel online. The questionnaire was completed by 76 respondents from different European countries, the United States and Australia. In order to analyze individual aspects influencing non-purchasing in an online environment, an exploratory factor analysis was performed.

Results: The factor analysis revealed that the two broad dimensions of reasons why consumers have never bought any ready-to-wear apparel online despite browsing are a misperception of product integrity and time-consuming searching. The results show that the proposed solutions to improve the online apparel experience, such as making custom apparel using advanced technologies, have a positive impact on the decision of the consumers to purchase on the online apparel market. It turned out that a high proportion of potential consumers are willing to share their body dimensions through 3D body scanning technology in order to improve the fit of the apparel.

Conclusion: According to the results, we expect that the advanced 3D body scanning technology would provide substantial progress regarding fit, visualization, and manufacturing of custom-made apparel when purchasing in online stores.
Multi-objective Optimization Algorithms with the Island Metaheuristic for Effective Project Management Problem Solving
Authors: Brester Christina , Ryzhikov Ivan , Semenkin Eugene 
Published: December 2017

Abstract

Background and Purpose: In every organization, project management raises many different decision-making problems, a large proportion of which can be efficiently solved using specific decision-making support systems. Yet such kinds of problems are always a challenge since there is no time-efficient or computationally efficient algorithm to solve them as a result of their complexity. In this study, we consider the problem of optimal financial investment. In our solution, we take into account the following organizational resource and project characteristics: profits, costs and risks.

Design/Methodology/Approach: The decision-making problem is reduced to a multi-criteria 0-1 knapsack problem. This implies that we need to find a non-dominated set of alternative solutions, which are a trade-off between maximizing incomes and minimizing risks. At the same time, alternatives must satisfy constraints. This leads to a constrained two-criterion optimization problem in the Boolean space. To cope with the peculiarities and high complexity of the problem, evolution-based algorithms with an island meta-heuristic are applied as an alternative to conventional techniques.

Results: The problem in hand was reduced to a two-criterion unconstrained extreme problem and solved with different evolution-based multi-objective optimization heuristics. Next, we applied a proposed meta-heuristic combining the particular algorithms and causing their interaction in a cooperative and collaborative way. The obtained results showed that the island heuristic outperformed the original ones based on the values of a specific metric, thus showing the representativeness of Pareto front approximations. Having more representative approximations, decision-makers have more alternative project portfolios corresponding to different risk and profit estimations. Since these criteria are conflicting, when choosing an alternative with an estimated high profit, decision-makers follow a strategy with an estimated high risk and vice versa.

Conclusion: In the present paper, the project portfolio decision-making problem was reduced to a 0-1 knapsack constrained multi-objective optimization problem. The algorithm investigation confirms that the use of the island meta-heuristic significantly improves the performance of genetic algorithms, thereby providing an efficient tool for Financial Responsibility Centres Management.
