The Regularizing Properties of Multistep Methods for First Kind Volterra Integral Equations with Smooth Kernels
Authors: Plato Robert 
Published: October 2016

Abstract
In this paper, quadrature methods for solving Volterra integral equations of the first kind with smooth kernels under the presence of noise in the right-hand sides are considered, with the quadrature methods generated by linear multistep methods. The regularizing properties of an a priori choice of the step size are analyzed, and the smoothness of the involved functions is carefully taken into consideration.
The balancing principle as an adaptive choice of the step size is also studied. It is considered in a version which sometimes requires less amount of computational work than the standard version of this principle. Numerical results are included.

Invertibility characterization of Wiener–Hopf plus Hankel operators on variable exponent Lebesgue spaces via even asymmetric factorization
Authors: Castro Luís P. , Silva Anabela S. 
Published: October 2016

Abstract
We obtain invertibility and Fredholm criteria for the Wiener–Hopf plus Hankel operators acting between variable exponent Lebesgue spaces on the real line.
Such characterizations are obtained via the so-called even asymmetric factorization,
which is applied to the Fourier symbols of the operators under study.
Urea-formaldehyde (UF) resins prepared by means of the aqueous phase of the catalytic pyrolysis of European beech wood. COST Action FP1105
Authors: Papadopoulou Electra , Kountouras Sotiris , Nikolaidou Zoe , Chrissafis Konstantinos , Michailof Chrysoula , Kalogiannis Konstantinos , A. Lappas Angelos 
Published: October 2016

Abstract
The aqueous phase resulting from the catalytic pyrolysis (AQcatPy) of biomass has been successfully applied for acidification of urea-formaldehyde (UF) resins. The resins were synthesized at a laboratory scale and characterized by gel permeation chromatography (GPC), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The bonding ability of the resins was tested through the preparation of particle boards (PBs). It was found that the UF resins prepared with AQcatPy as acidification medium have a similar performance to typical UF resins, where conventional chemicals like formic acid (FA) or acetic acid (AA) serve for pH adjustments. The new resins give PBs with somewhat improved thickness swelling (TS) values, while all other properties are at the same level.
Walking in the city: A case study of the streets in Brno
Authors: Kočková Jana 
Published: October 2016

Abstract
This paper is an ethnographic study of everyday walking practice in the city. The research was conducted in 2014-2015 in selected streets of Brno city and was based on a hybrid method of shared walking (go-along) coupled with observations and semi-structured interviews. As urban walking is recognized as a significant mode of travel, this paper aims to expand existing knowledge by contributing qualitative data. The key influence is the work of Michel de Certeau (1984) who understands walking as a practice of everyday life. Everyday walking helps shape physical spaces and this subsequently affects human behavior. In this article I will discuss how people relate to walking, how they act in urban space and what importance they attach to their behavior. Another aim is to ascertain how pedestrians behave while performing their everyday routine and how they interact with drivers and cyclists.
Moderne und Kultur. Über Genese und Funktionsweise literaturwissenschaftlicher Moderne-Begriffe
Authors: Stöckmann Ingo 
Published: October 2016

AbstractThe paper examines the inter-discursive relations between the naturalistic novel and early sociology in the late nineteenth century and consequently unfolds a yet-to-be-told history of modernity concepts commonly used in literary criticism today. The narrative and aesthetic implications of these concepts have often been discussed. However, their unquestioned inevitability on the level of representation and an understanding of modern culture can be observed and investigated against this historical background in particular. This allows for two tentative assumptions: First, the logical inconsistencies of the historical narrative inspected here have a continuing impact on ›classical‹ theories of modernity in general and affect their fundamental conceptual formation. Second, this kind of terminology of modernity was never modern in the first place.
Die größere Hoffnung in englischer Sprache. Cornelia Schaeffers Übersetzung von 1963
Authors: Bachleitner Norbert 
Published: October 2016

AbstractThe English translation of Aichinger’s novel appeared in 1963, that is at a time when her writing did not yet seem appropriate for a wider public. The American translator Cornelia Schaeffer therefore adapted the novel by ›clarifying‹ opaque phrases and ›normalizing‹ unusual expressions or by simply omitting them. She tries to provide her readers with a more or less realistic story of children trying to escape from Nazi terror. Furthermore, she does not adequately render leitmotifs such as Aichinger’s variations of the word »nachweisen « referring to the notorious (Arier-)Nachweis. Sometimes it is clear that deviations from the meaning of the source text are due to the lack of the translator’s command of German. Most interesting for comparative translation studies are passages that are open to interpretation in the German version, e.g. Ellen’s striving for the »Allererste«.
Übersetz mich über das Meer. Die größere Hoffnung auf Japanisch
Authors: Shindo Sugi 
Published: October 2016

AbstractDie größere Hoffnung was translated into Japanese by Takashi Yajima in 1981 and published in the »Fairy-Paperback« translation series. In his translation Yajima pays particular attention to the description of light. The keyword »night and fog« and the essay »In Praise of Shadows« by Junichiro Tanizaki are used as reference points for the analysis of this feature of Yajima’s translation. Furthermore, his reproduction of complex constellations in Aichinger’s text is analyzed, especially the comments and the rendering of pronunciation and meaning in the Japanese version.
Zur Übersetzung des Romans Die größere Hoffnung von Ilse Aichinger ins Russische
Authors: Naiditsch Larissa

AbstractIlse Aichinger’s novel Die größere Hoffnung was published in Russian in 1998 in the framework of the project Austrian library in St. Petersburg. The translator Elena Baevskaja is famous for her translations of French and German prose. The focus here is on the following topics: 1) the Jewish theme of the novel and its relevance for the Russian reader; 2) the rendering of recurring words and images (leitmotifs) in the novel; 3) the translation of images and lexemes concerning culturally and historically bound notions; 4) word play and other complicated cases; 5) examples of text explanation through translation.
Die größere Hoffnung in spanischer Sprache. Adan Kovacsis’ Übersetzung von 2004
Authors: Siguan Marisa 
Published: October 2016

AbstractThe article discusses the problems that arise when translating from German into Spanish due to the different structures of the two languages. Furthermore, the peculiarities of Aichinger’s style and the solutions offered by the translator are analyzed. In Aichinger’s language, poetical imagery, a dramatic and high tone, and intensity based on the concentration of expression all play a major role. The translator is well aware of these stylistic features, and does his best to render them adequately. On the whole, he presents a well readable Spanish text.
Eckensteher
Authors: Briese Olaf 
Published: October 2016

Abstract:This article explores the complex origins of the literary figure ‘Berliner Eckensteher’ around 1830. It analyses the sources of this figure in European visual and textual culture, its literary transformations and its different meanings. On the one hand, these figures were conceived as typical ‘biedermeierlich’, that is, as conforming to the social order, as drunken, dumb and harmless. On the other hand, and typical ‘vormärzlich’, they stood also for subversive protest against social repression and increasingly for the fight against reactionary politics. But: did Berlin ‘Eckensteher’ ever actually exist?

Widersprüchliche Optionen: Stationen der Künste 1913
Authors: Asendorf Christoph 
Published: October 2016

AbstractApart from their rather coincidental origin year, 1913, there is no apparent connection between a monument like the “Völkerschlachtdenkmal” in Leipzig (“Monument to the Battle of the Nations”) and the aesthetic manifestations of the avant-garde. These artistic expressions oscillate between opposite poles: weakness and desire for stability, refinement and primitivism, immanence and transcendence. It might be assumed that precisely these contradictory impulses lie at the heart of the rich and widely influential artistic outcome of this pre-war year.
Validation of the family needs assessment scale for Colombian families with children with intellectual disability

Published: October 2016

AbstractThis study documents the development and validation of the children’s version of the Family Needs Assessment (FNA) instrument for Colombia. The FNA is a scale that evaluates the needs of families with children with disabilities who are below the age of 18 years. To validate this scale, the research team identified the theoretical background regarding family members’ needs and performed a linguistic adaptation of the scale, which was reviewed to guarantee its validity through cognitive interviews and a pilot study. Results from the exploratory factor analysis (EFA) showed 72 items distributed in a 4-factor solution. Cronbach’s alpha coefficients for each factor and for the overall FNA scale were also estimated. Specifically, alpha computed from the correlation among the 72 items was 0.97 and ranged from 0.85 to 0.95 for the four factors. Findings from this study provided evidence to support the validity of the FNA for families with children with intellectual disability in Colombia. The findings also indicated that the FNA has the potential of contributing to a better understanding of inputs (e.g. needs of families with individuals with disability) with the aim of informing system decisions, enhancing policies, improving services and strengthening family-professional partnerships.
Self-healing phenomena of graphene: potential and applications
Authors: VijayaSekhar K. , Acharyya Swati Ghosh , Debroy Sanghamitra , Miriyala V. Pavan Kumar , Acharyya Amit 
Published: October 2016

AbstractThe present study investigates the self healing behavior of both pristine and defected single layer graphene using a molecular dynamic simulation. Single layer graphene containing various defects such as preexisting vacancies and differently oriented pre-existing cracks were subjected to uniaxial tensile loading till fracture occurred. Once the load was relaxed, the graphene was found to undergo self healing. It was observed that this self healing behaviour of cracks holds irrespective of the nature of pre-existing defects in the graphene sheet. Cracks of any length were found to heal provided the critical crack opening distance lies within 0.3-0.5 nm for a pristine sheet and also for a sheet with pre-existing defects. Detailed bond length analysis of the graphene sheet was done to understand the mechanism of self healing of graphene. The paper also discusses the immense potential of the self healing phenomena of graphene in the field of graphene based sub-nano sensors for crack sensing.

Kinetic study of CO2 reaction with CaO by a modified random pore model
Authors: Nouri S.M.M. , Ale Ebrahim H. 
Published: October 2016

Abstract
In this work, a modified random pore model was developed to study the kinetics of the carbonation reaction of CaO. Pore size distributions of the CaO pellets were measured by nitrogen adsorption and mercury porosimetry methods. The experiments were carried out in a thermogravimeter at different isothermal temperatures and CO2 partial pressures. A fractional concentration dependency function showed the best accuracy for predicting the intrinsic rate of reaction. The activation energy was determined as 11 kcal/mole between 550–700°C. The effect of product layer formation was also taken into account by using the variable product layer diffusivity. Also, the model was successfully predicted the natural lime carbonation reaction data extracted from the literature.

Authors: Thirugnanasambandham K. , Sivakumar V. , Shine K. 
Published: October 2016

Abstract
In this present study, chemical coagulation process (CC) treatment process was investigated under different conditions such as pH, ferric chloride dose, agitation time and settling time to treat bagasse wastewater using response surface methodology (RSM). The outcomes were evaluated using Pareto analysis of variance (ANOVA) and second order polynomial models were created with the aim of being able to predict the responses. Ideal conditions were observed to be as per the following: agitation time of 25 min, pH of 7, ferric chloride dose of 6 g/L and settling time of 60 min. Under these conditions, turbidity removal of 62%, COD removal of 67%, TDS removal 53% and sludge production of 32 mL/L were obtained with operating cost of 3.50 Rupee/L. The mechanism of CC was analyzed using XRD spectrum and founds to be adsorption.
Multifunctional oligoetherols and polyurethane foams with carbazole ring
Authors: Lubczak Renata 
Published: October 2016

Abstract
A new method of preparation of multifunctional oligoetherols containing carbazole ring is presented. The oligoetherols were obtained in the reaction of 9-(2,3-epoxypropyl)carbazole with sorbitol and oxiranes like ethylene and propylene oxide. The structure of obtained oligoetherols was determined by IR, H-NMR and MALDI-ToF spectroscopies. Physical properties of the products render them good candidates for preparing polyurethane foams. The foams were obtained and their properties were examined. It has been found that the foams are rigid at room temperature and their apparent density was 50–70 kg/m3. The water uptake was low, maximum to 6.5 mass%. Obtained foams have high thermal resistance. Dynamic thermal analysis of these foams showed that 5% mass loss was initiated at 250–300°C, while temperature of 50% mass loss was 370–404°C. Concomitantly the increase of compression strength was observed.
Separation/Preconcentration Techniques for Rare Earth Elements Analysis
Authors: Hu Bin , He Man , Chen Beibei , Jiang Zucheng 
Published: October 2016

AbstractThe main aim of this chapter exactly characterizes the contribution. The analytical chemistry of the rare earth elements (REEs) very often is highly complicated and the determination of a specific element is impossible without a sample pre-concentration. Sample preparation can be carried out either by separation of the REEs from the matrix or by concentrating the REEs. The separation of REEs from each other is mainly made by chromatography.At the beginning of REE analysis, the method of precipitation/coprecipitation was applied for the treatment of REE mixtures. The method is not applicable for the separation of trace amounts of REEs. The majority of the methods used are based on the distribution of REEs in a two-phase system, a liquid–liquid or a liquid–solid system. Various techniques have been developed for the liquid–liquid extraction (LLE), in particular the liquid phase micro-extraction. The extraction is always combined with a pre-concentration of the REEs in a single drop of extractant or in a hollow fiber filled with the extractant. Further modified techniques for special applications and for difficult REE separation have been developed. Compared to the LLE, the solid phase micro-extraction is preferred. The method is robust and easy to handle, in which the solid phase loaded with the REEs can be used directly for subsequent determination methods. At present, very new solid materials, like nanotubes, are developed and tested for solid phase extraction.

Published: October 2016

Abstract
Procainamide (4-amino-N-[2-(diethylamino) ethyl] benzamide) is a sodium channel blocker, which acts as an effective antiarrhythmic agent used in the treatment of a variety of atrial and ventricular arrhythmias. The aim of this study was to prepare 99mTc-procainamide complex, apply different chromatographic techniques for the assay of radiolabeling yield and study its biodistribution as a novel radiopharmaceutical for heart imaging. 99mTc-procainamide was obtained with a maximum labeling yield of 95.76±0.20% via direct labeling method under optimum conditions of 200 μg of procainamide, 300 μL of buffer (carbonate) at pH 11, 30 μg SnCl2·2H2O at room temperature (25°C) for 15 min. In terms of in vitro stability, the complex was stable for 3 h. Chromatographic evaluation using paper chromatography, thin layer chromatography, gel chromatography, and high performance liquid chromatography showed reliable results for measuring the radiochemical yield. Biodistribution study of 99mTc-procainamide showed ratios of heart/lung and heart/liver (6.38±1.50, 2.06±0.31, respectively at 30 min post injection) which was comparable to that of 99mTc-sestamibi (7.4±2.00, 0.97±0.10, respectively at 60 min, P<0.05).

Published: October 2016

AbstractCarbon nanotubes (CNTs) are considered as one of the most intensively explored nanostructured materials and have been widely used as a platform material for metal and semiconductor nanoparticles (NPs) due to their large and chemically active surface area. Several approaches have been described in the literature to immobilize NPs on the surface of CNTs. This report reviews the recent developments in this area by exploring the various techniques where nanotubes can be functionalized with NPs to improve the optical, mechanical, thermal, medical, electrical, and magnetic applications of CNTs.
Investigation of penetration into woven fabric specimens impregnated with shear thickening fluid
Authors: Kordani Naser , Sadough Vanini Ali 
Published: October 2016

Abstract
In this paper, the effect of weight fraction of nano silica (hydrophilic fumed silica particles) and molecular mass of polyethylene glycol (PEG) on the rheological properties such as the critical shear rate of fluids has been studied. Dynamic moduli based on strain and the effects of increasing the molecular weight are presented. Constructed samples with high-molecular-weight PEG have higher initial, final and critical viscosities. Also, higher molecular chains in the polymer and preventing the movement of most of these chains against the relative motion of liquid (viscosity) will cause higher viscosity in samples. Critical shear rate is lower in the provided samples with high-molecular-weight PEG. Polymer branches in these suspensions are absorbed by the surface of the particles. Due to OH bonds in the silica particles and also due to the presence of this bond in PEG, creating a hydrogen bond is likely. Such a hydrogen bond between the polymer yarn and the particle surface causes surface absorption of the particles. To show the effect of molecular weight on fibers, woven fabric specimens impregnated with shear thickening fluid (STF) have been examined by penetration and pressure test diagrams have been investigated. In a sample with higher molecular weight, displacement to yield point is higher and residence to penetration does not show much difference.
