Examining the Father-Child Relationship: A Theoretical Framework for Creating a Methodology
Authors: Fucsková Zuzana , Babinčák Peter , Kačmárová Monika 
Published: February 2022

Abstract
In Slovakia and the Czech Republic, little attention is paid to the father-child relationship. The aim of this theoretical study is to introduce methods for assessing the father-child relationship in early childhood. There are two methodologies for assessing sensitive and challenging play by fathers – the Sensitive and Challenging Interaction Play Scale – SCIP (Grossmann et al., 2002) and the quality of the father-child activation relationship – Risky Situation – RS (Paquette & Bigras, 2010). The study describes the SCIP and offers a theoretical definition of the basic constructs tackled in the SCIP methodology. The paper then describes the new RS procedure. Special attention is paid to activation theory, which forms the basis of the RS procedure. Finally, the paper contains suggestions for future in-depth investigations of the father’s role using adequate tools that take into consideration the uniqueness of the father-child relationship. The need to validate existing methods – also within Slovak culture – is emphasized.
Emotionally Engaged Parent Versus Professional Teacher: Strategies for Maintaining Borders Between the Dual Teacher-Parent Role in School
Authors: Hargašová Lucia 
Published: February 2022

Abstract
The paper presents findings on primary teachers’ and other school actors’ constructions of the teacher and parental role. Specifically, it focuses on strategies for maintaining borders between the personal (parent) and professional (teacher) roles in school environments in Slovakia. We approached the concepts of role and identity from the perspective of social constructivism and symbolic interactionism. Thirty-one interviews and focus groups with school actors were analysed using critical discourse analysis. In the next step, discourses on managing the dual role were analysed using thematic analysis. Results show participants described regulating or restricting verbal, emotional and behavioural expression, and engaged in favouritism avoidance as strategies for separating out the roles. All point to the need to eliminate favouritism as a key meaning in the construction of the teacher role through impartialness and parental role as favourably inclined to create inter-role conflict. We stress the importance of exploring teacher and parental roles in various circumstances in order to obtain a complex picture of negotiating these roles in everyday life.

Published: February 2022

Abstract
Grain boundary (GB) solute diffusion of Ge in Cu polycrystals was systematically investigated by the radiotracer serial sectioning technique using 68Ge and 71Ge isotopes. The diffusion measurements were carried out under conditions of Harrison’s B- (923–626 K) and C- (576–451 K) type diffusion regimes. In the B-type diffusion regime, the triple product P = s

The determined segregation coefficients s are discussed together with previous results on solute segregation in Cu and Ag, and it is concluded that the well-known Hondros relation, which relates segregation and bulk solute solubility, can generally be used only for a qualitative estimation of the segregation ability.

Published: February 2022

Abstract
Ultrafine-grained titanium produced by equal channel angular pressing and subsequent cold rolling is studied by X-ray diffraction. It is found that a texture exists in which the hexagonal basal planes are parallel to the longitudinal axis of the billet. The crystallite size distribution and the dislocation structure are determined by X-ray diffraction peak profile analysis. The median and the variance of the crystallite size distribution are obtained as m = 39 nm and σ = 0.14, respectively. The dislocation model of anisotropic broadening of peak profiles enables to determine the active slip systems. It was found that all three possible hexagonal Burgers vectors of dislocations exist, with the composition of 66% <a> type, 33% <c> type and 1% <c + a> type.
Contribution of dislocation substructures developed during cold rolling to the formation of rolling textures in Al–Mg alloys
Authors: Endou Seiichi , Inagaki Hirosuke 
Published: February 2022

Abstract
In order to investigate the mechanism of the development of rolling textures in Al –Mg alloys, hot bands of high-purity Al, Al-3 wt. %Mg and Al-5 wt. %Mg alloys were solution-treated at 450 °C and cold-rolled by varying rolling reductions up to 97%. Rolling textures of these specimens were investigated with the orientation distribution function analysis. Comparisons of the results of the texture analysis with those of the hardness measurement and transmission electron microscopy observations revealed that, in all specimens, the texture development occurred mainly at the later half of work hardening, i. e., at rolling reductions above 80 %, where dislocation substructures were well developed. In pure Al, in which well defined, elongated cell structures were developed, {112}<111> and {123}<634> components developed remarkably, whereas in the Al-5% Mg alloys, in which only dense dislocation tangles and ill defined small cells were developed, the development of {112}<111> and {123}<634> components was strongly suppressed. All these observations thus suggested that the development of rolling textures was strongly affected by the development of dislocation substructures, which occurred concurrently during rolling, and that the formation of elongated cell structures was more favorable for the development of rolling textures. In cold rolling, elongated cell structures may be the final form of dislocation substructures, providing both mechanical stability and orientation stability.
Controlled change in the plastic working conditions of metals in the plane state of strain
Authors: Bochniak Włodzimierz 
Published: February 2022

Abstract
In the investigations on plastic forming of Cu, Al and Pb, under conditions of plane state of strain, priority has been given to variants with a change in the loading scheme (modified channel die test). It has been found that a direct consequence of the application of such a procedure is a temporary, considerable decrease of the flow stress and its subsequent increase to a value exceeding that attained in a standard test. The reasons for such a behavior have been analysed.
Textures and precipitates in Ti-stabilized interstitial-free steel
Authors: Shin Eunjoo , Seong Baek-Seok , Kang Hee-Jae , Huh Moo-Young 
Published: February 2022

Abstract
Samples of titanium-stabilized interstitial-free steel were coiled at 600 and 700 °C. The effect of the coiling temperature on the formation of textures and precipitates during coiling, cold rolling and recrystallization annealing was studied by means of neutron texture measurements, small angle neutron scattering analysis and transmission electron microscopy observations. Whereas coiling at the lower temperature resulted in an insufficient scavenging of carbon in solid solution, coiling at the higher temperature promoted scavenging of carbon in solid solution, and consequently the formation of a large number of precipitates. The large amount of carbon in solid solution caused the retardation of softening in the cold-rolled sample during annealing below 700 °C. Upon annealing above 700 °C the impact of the coiling temperature on grain size and precipitates was not observed. The samples coiled at different temperatures exhibited a nearly identical cold rolling texture. However, the cold-rolled sample having a large amount of carbon in solid solution displayed a weak recrystallization texture.
Kinetics of the discontinuous precipitation of a liquid phase in Cu–In alloys
Authors: Gautam S. K. , Gupta S. P. 
Published: February 2022

Abstract
The morphology and growth kinetics of the discontinuous precipitation of liquid and depleted solid phases from a supersaturated solid solution has been studied. The transformation was carried out in the two-phase (liquid + solid α) field in the temperature range 996–1050 K in two Cu– In alloys containing 8.9 and 9.5 at.% In. A lamellar structure consisting of alternate lamellae of α and liquid phases has been observed to grow from the grain boundaries of the supersaturated α solid solution. The nucleation of the liquid droplets occurred at the grain boundary and a thin layer of liquid formed between the droplets. The liquid film started migrating resulting in the development of a lamellar structure. In both alloys the growth rate increased with increasing temperature of transformation but the interlamellar spacing decreased with increasing transformation temperature. The growth kinetics was analyzed using the models of Cahn and Petermann and Hornbogen and from a mass balance using Fick’s first law. From the diffusivity and activation energy values it can be concluded that the growth of the cellular structure occurs by solute transport through the liquid film.
Influence of homogenization on the processing map for hot working of as-cast Mg–2Zn–1Mn alloy
Authors: Sivakesavam O. , Prasad Y. V. R. K. 
Published: February 2022

AbstractProcessing maps have been developed for hot deformation of Mg–2Zn– 1Mn alloy in as-cast condition and after homogenization with a view to evaluate the influence of homogenization. Hot compression data in the temperature range 300 – 500 °C and strain rate range 0.001 – 100 s– 1were used for generating the processing map. In the map for the as-cast alloy the domain of dynamic recrystallization occurring at 450 °C and 0.1 s–1has merged with another domain occurring at 500 °C and 0.001 s– 1representing grain boundary cracking. The latter domain is eliminated by homogenization and the dynamic recrystallization domain expanded with a higher peak efficiency occurring at 500 °C and 0.05 s–1. The flow localization occurring at strain rates higher than 5 s–1is unaffected by homogenization.
Some characteristics of electrospark deposition
Authors: Lešnjak Andrej , Tušek Janez 
Published: February 2022

Abstract
The paper deals with some characteristics of electrospark deposition. A relevant device and the process are described, the material transfer is shown schematically, and the average droplet mass, the thickness of deposited layer, and the layer roughness are determined. Two types of substrate (tool steel, austenitic stainless steel), two types of shielding gas, (Ar, He), and three types of filler material, (WC, TiC, Stellite 6) were used. With some deposits, chemical analyses of deposit surfaces were performed and with some others through-thickness chemical analyses. Among the final conclusions the most important one is that the addition of a shielding gas results in a considerable increase in deposit quality. The device manufacturer, however, recommends deposition without the addition of a shielding gas.
Neurofeedback and neural self-regulation: a new perspective based on allostasis
Authors: Mirifar Arash , Keil Andreas , Ehrlenspiel Felix 
Published: February 2022

Abstract
The field of neurofeedback training (NFT) has seen growing interest and an expansion of scope, resulting in a steadily increasing number of publications addressing different aspects of NFT. This development has been accompanied by a debate about the underlying mechanisms and expected outcomes. Recent developments in the understanding of psychophysiological regulation have cast doubt on the validity of control systems theory, the principal framework traditionally used to characterize NFT. The present article reviews the theoretical and empirical aspects of NFT and proposes a predictive framework based on the concept of allostasis. Specifically, we conceptualize NFT as an adaptation to changing contingencies. In an allostasis four-stage model, NFT involves (a) perceiving relations between demands and set-points, (b) learning to apply collected patterns (experience) to predict future output, (c) determining efficient set-points, and (d) adapting brain activity to the desired (“set”) state. This model also identifies boundaries for what changes can be expected from a neurofeedback intervention and outlines a time frame for such changes to occur.
Quand l’éventail du désaccord laisse parler au-delà des paroles: Etude historico-sémiotique de la légende du Coup de l’Eventail
Authors: Khelil Lamya 
Published: February 2022

Résumé
Le présent travail de recherche retrace la scène mythique du Coup de l’éventail qui opposa le Dey d’Alger Hussein Pacha et le Consul français Pierre Deval en 1827. Nous examinons dans quelle mesure l’interprétation dudit incident pourrait entraver le recours à la sémiotique dans les études historiographiques en reposant sur les théories sémiotiques de Greimas, de Fontanille et de Zilberberg. L’analyse sémiotique des iconographies représentant l’incident a révélé à quel point ce dernier ne pourrait se désubjectiviser bien que Greimas ait déjà proposé de jumeler les deux étapes l’archivage et l’analyse qui devraient être menés par un actant collectif dans le but d’atteindre une «désubjectivisation totalitaire» des faits. S’ajoutant à cela la problématique du découpage temporel qui persiste, l’historien serait incapable d’étudier les modèles de transformation dans le même temps et dans le même ordre car les transformations jouissent d’un caractère irréversible. Or, les signes historiques sont exempts de virtualité, ce qui remet en cause l’intégrité du signe historique. Greimas espérait aboutir à travers le concept de simulacre à une forme du passé narrativisée et débrayée, l’énonciation va ainsi permettre de doter les éléments hétérogènes abondants du passé d’une valeur énonciative mais cela reste difficile à réaliser. Nous reconnaissons néanmoins que le ne pas pouvoir savoir épistémique est un composant légitime de l’incident historique.
Bidirectional volatility transmission between stocks and bond in East Asia – The quantile estimates based on wavelets
Authors: Živkov Dejan , Kovačević Jelena , Stankov Biljana , Stefanović Zoran 
Published: February 2022

AbstractThis paper investigates the volatility spillover effect between the national stock and bond markets in the five East Asian emerging countries. We use wavelet signal decomposing technique, GARCH models with different distribution functions and quantile regression. We find that the spillover effect is much higher in more turbulent times, than in calm periods, whereby this effect is stronger from stocks to 10Y bonds, thanvice-versa, and it applies for all the countries. Using wavelet signals, we determine that, in most cases, the volatility transmission is higher in short-term horizon, than in midterm and long-term. The effect is stronger in countries with the less developed financial markets (Thailand, Indonesia and Malaysia) than in countries with more developed financial markets (China and Korea), and this is particularly evident in direction from stock to bond markets. Wavelet coherence indicates low volatility correlation in short time-horizons and relatively high correlation in midterm and long-term, which applies for all selected countries. Wavelet cross-correlation indicates that volatility spillover shocks predominantly transmit from bond markets to stock market in more developed China and Korea, whereas volatility shocks from stock market spill over towards bond market in less developed Thailand and Indonesia in very short-time horizon (2–4 days).

Abstract

Objectives
The majority of research programs had been focused on extract from the fruiting body. However, fungal mycelium obtained by submerged cultivation also has higher pharmacological potential. The aim of this study was investigation of the antioxidant and antimicrobial potential of Ganoderma lucidum and Trametes versicolor fungal mycelium biomass obtained by submerged cultivation and liquid fluid.

Methods
The antioxidant activity was evaluated by comparing the oxidation kinetics of the reduced form of 2,6-dichlorophenolindophenol with atmospheric oxygen in the presence/absence of biological samples. A criterion for evaluating for assessing the antioxidant activity was the values of the inhibition constant of the oxidation reaction. Antimicrobial activity of the fungal extracts was performed by agar disc diffusion method.

Results
A comparative analysis of antioxidant potential of G. lucidum and T. versicolor mycelium biomass and liquid fluid was conducted for the first time. It was found that antioxidant activity of fungal biomass depends on the cultivation time. The most active were the fractions obtained on the 21st day of fungal cultivation. Fungal extracts were more effective against Gram-positive bacteria compared to Gram-negative bacteria, micromycete and yeasts.

Conclusions
The results showed that submerged cultivation of mushrooms has significant industrial potential.
Dimorphism of MnHAsO4(H2O): natural monoclinic krautite and its synthetic triclinic modification
Authors: Weil Matthias , Kolitsch Uwe , Stürzer Tobias 
Published: February 2022

Abstract
The crystal structure of natural krautite, MnHAsO4(H2O), was re-evaluated from a cotype specimen, confirming the previously reported monoclinic symmetry for this mineral (space group P21, Z = 8, a = 8.0093(5), b = 15.9372(10), c = 6.8065(4) Å, β = 96.534(2)° at room temperature, 5662 structure factors, 302 parameters, R1 = 0.0295, wR2 = 0.0770). Although hydrogen atoms could not be located from the single crystal X-ray diffraction study, the higher accuracy and precision of the results allowed to derive the hydrogen-bonding scheme (O⋯O = 2.55–2.90 Å) in the crystal structure of krautite. Crystals of synthetic MnHAsO4(H2O) were grown by mixing aqueous solutions of NH4H2AsO4 and MnSO4 and keeping the formed gel at 105 °C for several days. The obtained triclinic crystals were systematically and polysynthetically twinned by contact on (010). Separation of reflections from two individual domains made it possible to determine and refine the crystal structure (space group

The triclinic polymorph of MnHAsO4(H2O) does not show a direct group-subgroup relation with monoclinic krautite. Triclinic MnHAsO4(H2O) is closely related with other triclinic M
IIHAsO4(H2O) (M = Co, Cu, Zn, Mg) mineral phases. Quantitative structural comparisons between the five M
IIHAsO4(H2O) compounds revealed a high similarity between the Mn and Co members, and between the Zn and Mg members, respectively. Subtle distinctions between the two pairs are ascribed to a different hydrogen-bonding scheme. Although the Cu member has a similar hydrogen-bonding scheme as the Mn and Co pair, its structural similarity with triclinic MnHAsO4(H2O) is low due to the strain of the crystal structure caused by the Jahn-Teller distortions of the [CuO6] octahedra.
Design of Buried Equipment for the Collection of Urban Solid Waste

Published: February 2022

Abstract
Waste recovery systems are implemented around the world. These systems play a highly important role in the integrated waste management process. The constant technological evolution of this type of equipment aims to answer to global and European standards that increasingly require a reduction in the deposition of waste in landfills and a progressive growth of the recycling levels per capita. To allow the insertion of waste equipment in places where there are several limitations, such as the available space and the urban environment, buried equipment for the storage of waste appeared. This equipment has a large storage capacity, and because they are completely buried underground, only permanent deposition top bins are visible. This work was developed with the aim of improving buried underground waste disposal equipment, including the devices to comply with safety regulations and automated opening/closing mechanisms. The complete equipment can be divided into three parts: the liner, the buried structure, and the interface with the depositor of waste (through the deposition top bin). Because many of the available solutions are empirically based designs, there is a high margin to improve competitiveness, which reaches greater proportions in a scenario of economies of scale. The main equipment concept is presented, and structural analysis is accomplished by the finite element method, allowing for improved equipment to be proposed that replaces the current solution. Prototype fabrication/testing and cost analysis are also performed. A proposal to revise the current modular structure is finally presented, which allows for a cost and weight reduction of 6 % and 15 %, respectively.
Hermandades y Cofradías. Un estudio de caso, la cofradía del Señor SANT ROQUE DE LLODIO, de José Ignacio Urquijo Valdivielso
Authors: José Ignacio Urquijo Valdivielso  
Published: February 2022

Con este título José Ignacio Urquijo publica su tercer libro de Sociología de la Religión. Está editado en octubre de 2021 por Editorial ACISE, división editorial de la Asociación de Ciencias Sociales de Extremadura.
El libro comienza con un prólogo realizado por Marcelo Sánchez-Oro Sánchez presidente de ACISE que, entre otras cuestiones, remarca como: “El interés sociológico, en el marco de la sociología de las religiones es induda­ble. Por su parte, este mismo autor, para el caso de las hermandades establece un claro vínculo con la sociología al referir a Max Weber y su trabajo de 1922 titu­lado Wirtschaft und Gessellschaft, Grundriss der Verstehenden Soziologie. La base de las hermandades es la relación de parentesco entre hermanos, pero por exten­sión, se eleva a toda relación de amistad, confianza íntima y comparable, entre no hermanos. En un caso se trata de relaciones familiares; pero también, ya digo por extensión, de agrupación de carácter también primario, aunque no familiar. En esa segunda aceptación, el término hermandad ha tenido y tiene contenidos muy variados según los medios culturales. Algunas formas incluso de carácter político como fueron las germanías en Valencia, semejantes a las comunidades de Castilla, como menos significación orgánica, claro. Desde luego las herman­dades religiosas son muy variadas y próximas o equivalentes a órdenes, cofradías o congregaciones; muy en línea, esto último, de lo desarrollado por Urquijo Val­divielso en este destacado libro.”
