Multi-objective optimization of in-situ bioremediation of groundwater using a hybrid metaheuristic technique based on differential evolution, genetic algorithms and simulated annealing
Authors: Kumar Deepak , Ch Sudheer , Mathur Shashi , Adamowski Jan 
Published: January 2016

AbstractGroundwater contamination due to leakage of gasoline is one of the several causes which affect the groundwater environment by polluting it. In the past few years, In-situ bioremediation has attracted researchers because of its ability to remediate the contaminant at its site with low cost of remediation. This paper proposed the use of a new hybrid algorithm to optimize a multi-objective function which includes the cost of remediation as the first objective and residual contaminant at the end of the remediation period as the second objective. The hybrid algorithm was formed by combining the methods of Differential Evolution, Genetic Algorithms and Simulated Annealing. Support Vector Machines (SVM) was used as a virtual simulator for biodegradation of contaminants in the groundwater flow. The results obtained from the hybrid algorithm were compared with Differential Evolution (DE), Non Dominated Sorting Genetic Algorithm (NSGA II) and Simulated Annealing (SA). It was found that the proposed hybrid algorithm was capable of providing the best solution. Fuzzy logic was used to find the best compromising solution and finally a pumping rate strategy for groundwater remediation was presented for the best compromising solution. The results show that the cost incurred for the best compromising solution is intermediate between the highest and lowest cost incurred for other non-dominated solutions.

Published: January 2016

AbstractStructural, elastic, electronic and thermodynamic properties of ternary cubic filled skutterudite compound were calculated. We have computed the elastic modulus and its pressure dependence. From the elastic parameter behavior, it is inferred that this compound is elastically stable and ductile in nature. Through the quasi-harmonic Debye model, in which phononic effects are considered, the effect of pressure P (0 to 50 GPa) and temperature T (0 to 3000 °C) on the lattice constant, elastic parameters, bulk modulus B, heat capacity, thermal expansion coefficient α, internal energy U, entropy S, Debye temperature θD, Helmholtz free energy A, and Gibbs free energy G are investigated.

Authors: Chodun Rafal , Nowakowska-Langier Katarzyna , Zdunek Krzysztof 
Published: January 2016

AbstractEncouraged by recent studies and considering the well-documented problems occurring during AlN synthesis, we have chosen two diagnostic methods which would enable us to fully control the process of synthesis and characterize the synthesized aluminum nitride films. In our experiment we have compared the results coming from OES measurements of plasma and circulating power characteristics of the power supply with basic features of the deposited layers. The dual magnetron system operating in AC mode was used in our studies. Processes of aluminum target sputtering were carried out in an atmosphere of a mixture of argon and nitrogen. The plasma emission spectra were measured with the use of a monochromator device. Analyses were made by comparing the positions and intensities of spectral lines of the plasma components. The results obtained allowed us to characterize the sputtering process under various conditions of gas mixture compositions as well as power distribution more precisely, which is reported in this work. The measured spectra were related to the deposition rate, the structure morphology of the films and chemical composition. Our work proved that the use of plasma OES and circulating power measurements make possible to control the process of sputtering and synthesis of deposited films in situ.

A cognitive-pragmatic approach to error analysis
Authors: Włosowicz Teresa Maria 
Published: January 2016

Abstract
The purpose of the present paper is to analyze L2 and L3 production and comprehension from a cognitive-pragmatic point of view, taking into account Relevance Theory (Sperber and Wilson, 1986; Wilson and Sperber, 2006), Mental Models Theory (Johnson-Laird, 1983) and the Graded Salience Hypothesis (Giora, 1997). Special attention is paid to error analysis and to the detection of error sources, especially in the case of errors not attributable to transfer, interference or overgeneralization. The paper is based on three studies involving, first, L2 and L3 production (Study 1), both production and comprehension (Study 2) and L3 comprehension (Study 3). In general, the phenomena observed can be explained by a combination of Relevance Theory, Mental Models Theory and the Graded Salience Hypothesis. In fact, even when transfer is used as a strategy, its use is relevant to the learner, who assumes that it will be relevant to the recipient as well. The results also shed some light on the multilingual mental lexicon and multiple language processing.
The Influence Of Planning Decisions Regarding Land Evaluation Based On A Selected Local Real Estate Market
Authors: Foryś Iwona , Putek–Szeląg Ewa 
Published: January 2016

Abstract
The article analyzes the influence of planning decisions on changes taking place on the local real estate market. Three stages of the planning process are studied in particular, i.e.: the passing of the study of conditions and directions of spatial development, the Commune Council Resolution on initiating the formulation of a local spatial development plan, and finally the Resolution on accepting the local plan, as well as the effects of these activities on the land value in a given real estate market in Stargard Szczeciński, in the West-Pomeranian (Zachodniopomorskie) Province of Poland. The object of the research is to identify the indicated relationships on a given real estate market, on which respective spatial planning stages can be distinguished, as well as the strength and course of the analyzed relationships. The study will verify the research hypothesis regarding the strength and directions of the effects of planning decisions as the direct and indirect reasons behind price changes on the real estate market. The analysis uses data from the Price Register and the District Starosty Values, along with statistical and public information data and the authors' own studies.
Exchange Rate Risk On The Mortgage Market
Authors: Siemińska Ewa , Krajewska Małgorzata 
Published: January 2016

Abstract
Strict connections of the real estate market with the financial market are an unquestionable phenomenon at every level of investing, starting from the lowest individual investor, and finishing with national and transnational players. One of the more interesting examples of such a dependency is the problem of the risk of financing the real estate market, which results from numerous macro-, mezo- and microeconomic conditions, including, inter alias, the phenomenon of capital migration, supranational bank regulations or the development of currency exchange rates on world markets. The most recent example of such a dependency is, among others, the decision of the National Bank of Switzerland from the beginning of 2015 to abandon the Swiss franc-euro cap, which will go down in the history of the world financial market. Its global effects will surely be very difficult to assess, while the resulting turbulences and consequences for many (institutional, corporation and individual) market participants cause, on the one hand, awaiting a reaction and actions aimed at helping entities affected by the consequences of the mentioned decision and, on the other, many questions and doubts.
The paper will present current selected aspects concerning currency risk in the context of financing the residential real estate market and the directions of actions prepared in reaction to the abovementioned risk. Polish conditions will be presented against the background of examples of foreign solutions.
The aim of the work is to present:

the essence of currency risk in the context of the current financial situation of the Polish banking sector,

the most important directions of proposals for remedial actions aimed at mitigating the effects of the significant increase in the exchange rate of the Swiss franc in relation to the Polish currency,

a short overview of selected solutions/regulations regarding the exchange rate risk of mortgages taken out in a foreign currency in other countries.

The method employed was the critical analysis of the most-recent reports and recommendations of the National Bank of Poland, Polish Financial Supervision Authority, Polish Banking Union, and other experts on the subject of financing the real estate market, as well as a comparative analysis of solutions regarding currency risk in selected countries.
The Concept Of A Sustainable Approach To Corporate Real Estate Management
Authors: Ziemba Ewa , Śmietana Katarzyna , Ramian Tomasz , Kania Krzysztof 
Published: January 2016

Abstract
This paper is conceptual in nature and presents the assumptions of a holistic approach to corporate real estate management. The approach is based on the imperative of sustainability, which has become a determinant of the proposed Sustainable Corporate Real Estate Management (SCREM) model. Moreover, the authors indicate that in addition to the presence of the sustainability imperative, corporate real estate management requires the integration and formalization of knowledge about the concepts of corporate real estate management (CREM) with those of corporate social responsibility (CSR). This approach is intended to enable the identification and improvement of real estate management processes and, as a result, contribute to more efficient and effective corporate real estate management and continuous and flexible development of enterprises, as well as boosting economic growth and building prosperity for present and future generations.
One of the First Liturgical Hymns of the Eastern and Western Christian Church: the Great Doxology – Gloria in excelsis Deo
Authors: Diaconu George 
Published: January 2016

Abstract
The doxological character is one of the essential aspects of the Christian worship, taken from the Hebrew divine worship. Thus, the doxological character of many Christian prayers and liturgical hymns represents the foundation and at the same time the key which reveals and explains the theology of the Creation, its mystery and purpose. The role of the Creation is to praise the Creator, as invited conclusively by the last verse of the last canonical Psalm: ”Let everything that has breath praise the Lord!” (Ps. 150, 6). We will bring to the forefront of our debate the Great Doxology, one of the first liturgical hymns of the three basic doxological structures (the small, the great and the maximum doxologies) of the Eastern and Western Christian Church.
Communication Difficulties between Different Liturgical-Musical Paradigms:
Authors: Grăjdian Vasile 
Published: January 2016

Abstract
Contemporary ecumenical efforts face considerable difficulties due to differences of liturgical and musical paradigm between different confessions. Therefore, in opposition to a vision that is of secular inspiration and often eclectically and syncretically built in ecumenical manifestation, the Orthodox Church presents a traditional liturgical-musical perspective, a cosmic and soteriological typology, whose cyclical arrangement and liturgical hymns share a sacramental connection with divine revelation.
Overlap Between Ulerythema Ophryogenes and Keratosis Follicularis Spinulosa Decalvans: a Case Report
Authors: Stojanović Slobodan , Vučković Nada , Jovanović Marina 
Published: January 2016

Abstract
Ulerythema ophryogenes and keratosis follicularis spinulosa decalvans are rare folliculocentric keratotic disorders, from the group of follicular genokeratoses, characterized by keratosis pilaris atrophicans: follicular keratotic papules, sometimes with surrounding erythema, which eventually result in fibrosis, atrophy, progressive scarring and permanent hair loss. Ulerythema ophryogenes begins at birth or soon thereafter; it involves the lateral eyebrows, spreads medially and eventually affects the entire eyebrows, cheeks, and less frequently, forehead and asjecebt scalp. Involvement of the scalp has apparently not been reported in cases in which the eyebrows were predominantly involved. In addition to sporadic cases, ulerythema ophryogenes has been reported among relatives. Keratosis follicularis spinulosa decalvans is also a genetically heterogeneous syndrome which begins in infancy or childhood by involving hair bearing skin, especially the scalp; rarely it is confined to the face involving only eyebrows and eyelashes, but affects predominantly the scalp, leading to severe progressive cicatricial alopecia. Both conditions tend to progress until puberty.
The authors present a case of an otherwise healthy 19-year-old male patient, with absence of lateral eyebrows since childhood, which spread symmetrically and medially, until puberty affecting the entire eyebrows, whereas the eyelashes were completely spared. On examination, skin findings on the face, trunk and extremities pointed to ulerythema ophryogenes: apart from hair loss, the lateral eyebrows were highly erythematous; a great number of disseminated follicular, slightly keratotic papules (keratosis pilaris) pin- or match-head sized, were seen on the trunk, extensor surface of the arms and legs, as well as the buttock, and on palpation the skin felt like a “nutmeg grater”. However, follicle-based erythematous papules (focal patchy alopecia) were found not only along the eyebrows but also partly in the parietal capillitium forming focal patchy alopecia, which is a finding characteristic for keratosis follicularis spinulosa decalvans; the histopathological analysis of the biopsy specimens taken from the parietal capillitium has confirmed the clinical diagnosis.
Cytogenetic analysis showed no karyotypic abnormalities. Family history showed that the patient’s mother and maternal grandfather also suffered from hair loss especially of the lateral eyebrows.
This paper presents an overlap between two rare follicular genokeratoses in a young male with a positive family history, who presented with ulerythema ophryogenes involving not only the eyebrows, but also the scalp, in the form of parietal, focal cicatricial patchy alopecia.
Visualization and Comparison of Single and Combined Parametric and Nonparametric Discriminant Methods for Leukemia Type Recognition Based on Gene Expression
Authors: Ćwiklińska-Jurkowska Małgorzata M. 
Published: January 2016

Abstract
A gene expression data set, containing 3051 genes and 38 tumor mRNA training samples, from a leukemia microarray study, was used for differentiation between ALL and AML groups of leukemia. In this paper, single and combined discriminant methods were applied on the basis of the selected few most discriminative variables according to Wilks’ lambda or the leave-one-out error of first nearest neighbor classifier. For the linear, quadratic, regularized, uncorrelated discrimination, kernel, nearest neighbor and naive Bayesian classifiers, two-dimensional graphs of the boundaries and discriminant functions for diagnostics are presented. Cross-validation and leave-one-out errors were used as measures of classifier performance to support diagnosis coming from this genomic data set. A small number of best discriminating genes, from two to ten, was sufficient to build discriminant methods of good performance. Especially useful were nearest neighbor methods. The results presented herein were comparable with outcomes obtained by other authors for larger numbers of applied genes. The linear, quadratic, uncorrelated Bayesian and regularized discrimination methods were subjected to bagging or boosting in order to assess the accuracy of the fusion. A conclusion drawn from the analysis was that resampling ensembles were not beneficial for two-dimensional discrimination.

Published: January 2016

Abstract
Enhancement of teaching using digital materials is rapidly entering the world of medical studies. Creation of a self-learning environment supported with self-tests is received well, or even enthusiastically, among students. On the other hand, there is a relatively large group of opponents among university teachers, who do not see the need for changes in teaching and testing methodology to be made. This attitude may be surfacing as a result of anxiety connected with implementing new technologies in teaching medical subjects, as well as the belief that implementing new technologies does not have an immediate effect on learning quality. The authors of this article attempt to demonstrate that a thoughtful choice of e-learning platform facilitates the process of implementing online learning and testing aids in medical faculties. The second part of the article presents initial results of studies concerning the efficiency of learning enhanced with self-tests. Our analysis details the results of exams in pathophysiology taken by students of the medical faculty at the Poznan University of Medical Sciences. After the course, an evaluation survey was completed by 195 students concerning the quality of teaching with the use of the OLAT (Online Learning and Training) e-learning portal. It showed that students had positive attitudes toward learning with the use of online materials, particularly with regard to the use of self-tests, which allowed students to check their knowledge independently in exam-like conditions. The article that follows is targeted at those teachers who are interested in implementing a self-study and electronic knowledge evaluation environment for their courses, not necessarily in medical subjects.
Dynamic Process Analysis In Cutting Zone During Machining Of Nickel Alloys
Authors: Czán Andrej , Šajgalík Michal , Martikáň Anton , Mrázik Jozef 
Published: January 2016

Abstract
To generally improve effectivity of parts production and metal cutting process, there are used process models of super alloys together with finite element modeling simulations. Advanced measurement methods of the process could improve and verify the accuracy of these models. These methods cause many error sources when using empiric or exact methods such as infrared radiation thermography to measure the temperature distribution of the tool, workpiece, and chip during metal cutting. Measuring of metal machining is challenging due to factors such as the high magnification required, high surface speeds and deformations, micro-blackbody effects, changing emissivity and deformations present at metal cutting. As part of an ongoing effort to improve our understanding of uncertainties associated with these measurement methods, multimeasurement sets of experiments were performed. First set of measurements observed connection between surface temperature and the internal temperature of the cutting tool. This was accomplished by measuring the temperature using a thermal camera in cutting zone. Second set performed high-speed scan of dynamic processes such as formation of elastic and plastic deformation. During this operation was applied high-speed scannning system using macro conversion lens for monitoring of micro-structural changes in deformation areas. Next necessary applied set is recording of dynamic processes by implementation of piezoelectric measurement device for monitoring of cutting forces. The outputs from multimeasuring system are the basis for verification of theoretical knowledge from this field and elimination of uncertainties, which arise by using computer simulation systems.

Authors: Pilc Jozef , Drbúl Mário , Stančeková Dana , Varga Daniel , Martinček Juraj , Kuždák Viktor 
Published: January 2016

Abstract
Increased use of forging tools in mass production causes their increased wear and creates pressure to design more efficient renovation process. Renovation is complicated because of the identification of cracks expanding from the surface to the core material. Given that the production of forging tools is expensive, caused by the cost of tool steels and the thermo-chemical treatment, it is important to design forging tool with its easy renovation in mind. It is important to choose the right renovation technology, which will be able to restore the instrument to its original state while maintaining financial rentability. Choosing the right technology is difficult because of nitrided and heat-treated surface for high hardness and wear resistance. Article discusses the use of non-destructive method of detecting cracks taking into account the size of the cracks formed during working process.

Published: January 2016

Abstract
Beside cutting speed, shift is another important parameter of machining. Its considerable influence is shown mainly in the workpiece machined surface microgeometry. In practice, mainly its combination with the radius of cutting tool tip rounding is used. Options to further increase machining productivity and machined surface quality are hidden in this approach. The paper presents variations of the design of productive cutting tools for lathe work and milling on the base of the use of the laws of the relationship among the highest reached uneveness of machined surface, tool tip radius and shift.
