Published: August 2020

Abstract
Numerous investigations on the antioxidant properties of different plant tissue extracts are available in literature, but few studies on the effect of thermally modified wood on secondary metabolites were carried out up to now. This study highlights the influence of the thermal modification of Castanea sativa Mill. wood on total content of antioxidant compounds and consequently on its antioxidant activity. In addition, a chemical profile by Gas Chromatography–Mass Spectrometry (GC–MS) of the extractives was carried out. Wood of chestnut, thermally modified at 180 °C for 3 h, was used to obtain wood meal which was subjected to different extraction techniques, as maceration extraction (ME), ultrasound assisted extraction (UAE) and accelerated solvent extraction (ASE). The total content of principal antioxidant compounds, such as polyphenols, flavonoids and tannins, as well as the evaluation of antioxidant capacity by using different in vitro assays were determined. Relative Antioxidant Capacity Index (RACI), which is used to compare all antioxidant parameters, has also been applied. The study demonstrated a positive influence on chemical compounds present in C. sativa Mill wood originating from the thermal modification process. Thus, is possible to consider thermal modification as a promising strategy to improve the antioxidant activity of chestnut wood extractives.
Heuristic study on the interaction between heat exchange and slow relaxation processes during wood moisture content changes
Authors: Willems Wim 
Published: August 2020

Abstract
“Non-Fickian” diffusion of wood moisture refers to the unexplained anomalous behaviour of water vapour sorption in wood. The depression of moisture diffusion rates in thin sections of wood tissue during moisture content change at high relative humidity is one of the least-understood aspects of “non-Fickian” diffusion. In a previous work, a rate-limiting effect by two cooperative couplings of moisture and heat transfer, was shown to generate some signature features of “non-Fickian” diffusion. The present work aims to heuristically study the simultaneous action of this thermal rate-limiting effect and intrinsic slow relaxation processes in wood. Using an analytical non-geometrical model, exact solutions are obtained which show that the thermal rate-limiting effect acts directly and equally on diffusion and all relaxation processes, effectively time-stretching the entire dynamic wood moisture response. The magnitude of the time-scaling effect is proportional to the coupling strength between heat and mass transfer, which increases progressively with the relative humidity.
A review on life cycle assessments of thermally modified wood
Authors: Candelier Kévin , Dibdiakova Janka 
Published: August 2020

AbstractThis review compiles various literature studies on the environmental impacts associated with the processes of thermal modification of wood. In wood preservation field, the wood modification by heat is considered as an ecofriendly process due to the absence of any additional chemicals. However, it is challenging to find proper scientific and industrial data that support this aspect. There are still very few complete studies on the life cycle assessment (LCA) and even less studies on the environmental impacts related to wood heat treatment processes whether on a laboratory or on an industrial scales. This comprehensive review on environmental impact assessment emphasizes environmental categories such as dwindling of natural resources, cumulative energy intake, gaseous, solid and liquid emissions occurred by the thermal-treated wood industry. All literature-based data were collected for every single step of the process of wood thermal modification like resources, treatment process, transport and distribution, uses and end of life of treated wood products.

Published: August 2020

AbstractSoft-contact of molten steel can be achieved by applying a high-frequency electromagnetic field above the mold of continuous casting, which can effectively eliminate surface defects and achieve billets with no cracks and no oscillation marks. It also has some influence on the mold flux. In this study, the effect of a high-frequency electromagnetic field (20 kHz) on a mold flux flow field was simulated using a finite element software, and the slag film was extracted using a slag film simulator. The effect of the high-frequency magnetic field on the microstructure of the mold flux was analyzed using X-ray diffraction, Raman spectroscopy, and mineral phase testing. The results show that the high-frequency electromagnetic field disrupts the orderly movement and increases the movement rate of the liquid flux. The precipitate phase of the slag film did not change, but the silicate dimer Q1 decreased, the chain Q2 increased, and the network degree was increased. The slag film structure changed from the original two-layer form of crystalline layer–glass layer into a three-layer form of crystal layer–glass layer–crystal, and the crystallization ratio increased by 35% on average. The grain-size melilite granularity was reduced from the original 0.12 to 0.005 mm.

Authors: Soboleva Maja 
Published: August 2020

Abstract
The paper focuses on the rediscovery of Misch’s A History of Autobiography and its relevance to the problem of self-knowledge and self-esteem. Misch’s work is used to reconstruct a new aspect of self-esteem and to demonstrate that self-esteem can be interpreted as an early historical form of self-knowledge. In particular, self-esteem is characterized as a kind of self-knowledge in the category of the Other, that is, self-esteem appears to be self-knowledge derived from the social perspective regarding the individual.
Esteem and self-esteem as an interweaving polarity. Max Weber´s analysis from the Protestant ethic to the ideal-type of politician
Authors: Senigaglia Cristiana 
Published: August 2020

Abstract
Although Max Weber does not specifically analyze the topic of esteem, his investigation of the Protestant ethic offers interesting insights into it. The change in mentality it engendered essentially contributed to enhancing the meaning and importance of esteem in modern society. In his analysis, Weber ascertains that esteem was fundamental to being accepted and integrated into the social life of congregations. Nevertheless, he also highlights that esteem was supported by a form of self-esteem which was not simply derived from a good social reputation, but also achieved through a deep and continual self-analysis as well as a strict discipline in the ethical conduct of life. The present analysis reconstructs the different aspects of the relationship between social and self-esteem and analyzes the consequences of that relationship by focusing on the exemplary case of the politician’s personality and ethic.
Posttraumatic growth after the loss of a loved one in relation to ruminations and core beliefs
Authors: Záhorcová Lucia , Prielomková Andrea 
Published: August 2020

Abstract
The goal of this study was to examine the relationship between posttraumatic growth, ruminations, and core beliefs in grieving individuals after the loss of a loved one. The participants were 140 bereaved individuals (122 women, 18 men; M = 38.40; SD = 13.96). The results showed that posttraumatic growth was positively related to intrusive and deliberate ruminations; however, it was positively predicted only by deliberate ruminations. Core beliefs disruption was also positively related to deliberate and intrusive ruminations, but only deliberate ruminations positively predicted core beliefs. Moreover, posttraumatic growth is positively related to grief after the loss but unrelated to the time elapsed since loss. Higher posttraumatic growth was found in individuals who had experienced a sudden loss and loss of a close family member. Overall, the study shows that deliberate ruminations, for example about the meaning of the loss and its consequences, can stimulate posttraumatic growth in bereaved individuals.
Phenomenology in Central Europe: Philosophy from the margins
Authors: Vydrová Jaroslava 
Published: August 2020

Abstract
The aim of the paper is twofold: first, to enrich the factual historical record of the phenomenological movement in the second half of the 20th century in a Central European context by presenting two representatives of this movement who are now relatively unknown in the Czechoslovak philosophical milieu (Marie Bayerová and Josef Cibulka). The genealogy of this stream of phenomenology has been shaped by the difficult conditions under which philosophy was conducted. The second aim is to use the genealogy to describe the type of phenomenology that developed in this milieu. The article considers minor figures in the phenomenological movement, by exploring philosophy, both “in margine” and from the centre. It also consider the concept of “state of emergency”. Taking these pointers of philosophical analysis (elaborated by Jan Patočka and Milan Šimečka in their time) we reveal the anthropological conditions of philosophizing and the type of phenomenology.
The anthropological foundations of Buber’s cosmic vision of dialogical life
Authors: Bizoň Michal 
Published: August 2020

Abstract
This paper provides an analysis of Martin Buber’s not very well-known essay “Distance and Relation”, which is his most relevant contribution to philosophical anthropology. In the essay, which was published almost thirty years after the publication of his most famous book, I and Thou, Buber elaborated on the anthropological foundations of his cosmic vision of dialogical life. The central question is “How is man possible?” Buber’s answer is very important to the further development of his principle of dialogue in psychology (primarily his notion of confirmation) and philosophy of art, but it is not quite clear how compatible it is with some of his earlier theses from I and Thou. In particular, the relation between “distance” and the I-It relation is unclear. There are two seemingly contradictory statements: “In the beginning is the relation” and “The primal distance is a presupposition of the relation”. The aim of this paper is to examine these anthropological foundations and to elucidate this apparent contradiction.
The Shared View Paradigm in Asymmetric Virtual Reality Setups

Published: August 2020

Abstract
Asymmetric Virtual Reality (VR) applications are a substantial subclass of multi-user VR that offers not all participants the same interaction possibilities with the virtual scene. While one user might be immersed using a VR head-mounted display (HMD), another user might experience the VR through a common desktop PC. In an educational scenario, for example, learners can use immersive VR technology to inform themselves at different exhibits within a virtual scene. Educators can use a desktop PC setup for following and guiding learners through virtual exhibits and still being able to pay attention to safety aspects in the real world (e. g., avoid learners bumping against a wall). In such scenarios, educators must ensure that learners have explored the entire scene and have been informed about all virtual exhibits in it. According visualization techniques can support educators and facilitate conducting such VR-enhanced lessons. One common technique is to render the view of the learners on the 2D screen available to the educators. We refer to this solution as the shared view paradigm. However, this straightforward visualization involves challenges. For example, educators have no control over the scene and the collaboration of the learning scenario can be tedious. In this paper, we differentiate between two classes of visualizations that can help educators in asymmetric VR setups. First, we investigate five techniques that visualize the view direction or field of view of users (view visualizations) within virtual environments. Second, we propose three techniques that can support educators to understand what parts of the scene learners already have explored (exploration visualization). In a user study, we show that our participants preferred a volume-based rendering and a view-in-view overlay solution for view visualizations. Furthermore, we show that our participants tended to use combinations of different view visualizations.

Published: August 2020

AbstractThe temperature effect on VO2 thin films synthesized by RF sputtering on their morphological, optical, electrical properties and their activity in the photocatalytic degradation of methylene blue and naproxen was studied. Characterization results presented microcrystallinity for VO2 films treated at 50 and 100 °C. Nevertheless, the untreated films and films treated at 200 °C revealed characteristic peaks of monoclinic and tetragonal phases. SEM micrographs with elemental mapping of VO2 films showed granular morphology and a good oxygen dispersion along the film surface, possibly due to a restructuring on the film occasioned by particle coalescence and vanadium oxide island conformation. The electronic transmittance spectra showed the d–d transition characteristic for the square-pyramidal stereochemistry of vanadium (IV) ion, where the optical band interval was high for films treated at 50 °C. Raman spectroscopy results presented an increment in the V = O/V–O ratio as a function of temperature, probably related to superficial vanadium species formation. X-ray spectroscopy results showed the Onon-lattice/Olattice ratio values higher for films treated at 50 °C than the other films, related to an oxide character. The V 2p fit results presented V4+, V5+ regions and satellites for VO2 films thermal treated at 50 °C. The electrical resistivity on the VO2 films decreased as a function of temperature. Finally, the VO2 films thermal treated at 50 °C had higher photocatalytic activity in the degradation of methylene blue and naproxen compared to the other VO2 films, possibly associated with high electron mobility between the surface and the bulk, where the oxygen vacancies act as recombination sites for the e−/h+ pairs during photocatalytic degradation.

Published: August 2020

Abstract
Propolis has known as an aromatic resin which possesses several health beneficial properties such as antimicrobial and antioxidant due to bioactive and its complex composition. Propolis has been utilized in the form of extract; however, the application in food is limited due to its insolubility in water and undesirable sensory characteristics. Encapsulation of propolis using spray drying method with addition maltodextrin with or without arabic gum could reduce the undesirable sensory characteristic, protect bioactive compounds, and increase its availability in water-soluble matrices. The total bioactive compounds were evaluated before and after the drying process in order to know the ability of matrices wall to protect it. Physical properties such as hygroscopicity and surface structure were evaluated. Maltodextrin and arabic gum ratio affect phenolic content which is in a range of 0.0425–0.0445%, and also flavonoid content in a range of 0.00273–0.00415%. The coating agent ratio also affects the hygroscopicity which is in a range of 12.01–14.06% and moisture content which is in a range of 4.65–7.71%. The SEM images show that the cracks and hollows are often on the microcapsule surface, but the particle size is more homogeneous.

Abstract
Ultrasonic evaporator is a new type of evaporation equipment using ultrasonic technology to assist evaporation and concentration. It is especially suitable for the materials which are easy to scale and foam. Due to the complexity of heat and mass transfer during ultrasonic technology to assist liquid evaporation process, there are few reports on the energy consumption of ultrasonic evaporation. In this paper, the effects of ultrasonic density, evaporation temperature, and feed flow rate on the total energy consumption of ultrasonic evaporation were studied and tap water was selected as experimental material. It was found that the optimal condition for this ultrasonic evaporator were the ultrasonic power density of 4 × 10−5 W/m2, the evaporation temperature of 65 °C, and the feed rate of 1.389 × 10−5 m3/s. According to the orthogonal test and analysis of variance, it can be obtained that the influence of evaporation temperature on total energy consumption is the largest, the second is feed flow rate, and ultrasonic power density has the least influence.

Unpacking the hidden curriculum in nursing education: clinical placements abroad
Authors: St-Amant Oona , Sutherland Nisha 
Published: August 2020

AbstractMany Canadian nursing programs endorse clinical placements abroad. We critically examined the hidden curriculum embedded in clinical placements seeking to provide a ‘global’ experience. Using purposeful sampling, we interviewed a total of 18 participants, including eight faculty, eight students and two placement coordinators. Data were analyzed using initial and focused coding, supported by NVivo. After generating themes from the coded data, we adapted Hafferty’s (1998) framework to further analyze the theme of the hidden curriculum. The findings illuminate how policies sustained international experience as a privileged endeavour, with restricted access based on grades. Placements incorporated little evaluation of benefits for local communities. Few resources were allocated to students for such placements, as many students paid for their placement. The institutional terms ‘international and global experience’ denoted interactions with cultural “Others”. We recommend that nursing programs attend to hidden practices that sustain clinical placements abroad as prestigious, commodified experiences.
Bright and dark optical solitons for the generalized variable coefficients nonlinear Schrödinger equation
Authors: El-Shiekh Rehab M. , Gaballah Mahmoud 
Published: August 2020

Abstract
In this paper, the generalized nonlinear Schrödinger equation with variable coefficients (gvcNLSE) arising in optical fiber is solved by using two different techniques the trail equation method and direct integration method. Many different new types of wave solutions like Jacobi, periodic and soliton wave solutions are obtained. From this study we have concluded that the direct integration method is more easy and straightforward than the trail equation method. As an application in optic fibers the propagation of the frequency modulated optical soliton is discussed and we have deduced that it's propagation shape is affected with the different values of both the amplification increment and the group velocity (GVD).

Abstract
Recently, S. K. Mahato and P. D. Srivastava [A class of sequence spaces defined by 𝑙-fractional difference operator, preprint 2018, http://arxiv.org/abs/1806.10383] studied 𝑙-fractional difference sequence spaces.
In this article, we intend to make a new approach to introduce and study some lambda 𝑙-fractional convergent, lambda 𝑙-fractional null and lambda 𝑙-fractional bounded sequences over 𝑛-normed spaces.
Various algebraic and topological properties of these newly formed sequence spaces have been explored, and some inclusion relations concerning these spaces are also established.
Finally, some characterizations of the newly formed sequence spaces are given.
Biosurveillance: A Modern Look
Authors: Brooks James Lee 
Published: August 2020

Abstract
The early part of the twenty-first century saw a revolution in the field of Homeland Security. The 9/11 attacks, shortly followed thereafter by the Anthrax Attacks, served as a wakeup call to the United States and showed the inadequacy of the current state of the nation’s Homeland Security operations. Biodefense, and as a direct result Biosurveillance, changed dramatically after these tragedies, planting the seeds of fear in the minds of Americans. They were shown that not only could the United States be attacked at any time, but the weapon could be an invisible disease-causing agent.
From Intuitions to Anarchism?
Authors: Gordon David 
Published: August 2020

AbstractWhen libertarian political philosophy attracted wide public notice in the 1970s, a common view was that the distinctive individual rights advocated in libertarian theory required grounding in a theory of ethics. Recently, this view has come under challenge. It has been argued that resort to such grounding in ethical theory is unneeded. An appeal to common sense intuitions suffices to justify libertarianism. First, a brief account of libertarianism will be presented. Then, some examples of the older, pro-grounding position will be discussed. Then, the principal defense of the newer view, Michael Huemer’sThe Problem of Political Authority,will be examined. This discussion constitutes the substance of the present paper. The principal contention of the present article will be that the argument to libertarianism from intuitions does not succeed. In conclusion, it will be suggested that a return to the earlier, grounding view is indicated for philosophers who wish to defend libertarianism.
Is the Infringement of a Treaty a Fault?
Authors: Auvray Françoise 
Published: August 2020

Abstract
This contribution deals with the wrongful behaviour of public authorities, in this case in particular the Belgian State, and delves into a challenge that the multi-levelled legal order poses for the national tort system. It inquires how the violation of an international treaty relates to liability in the national legal system. More specifically, the author examines if it is necessary, when dealing with state liability, to limit the concept of fault to the infringements of international treaties with direct effect, excluding the violation of those without such effect.
