The Compositions: Biodegradable Material – Synthetic Resins as Moulding Sands Binders
Authors: Major-Gabryś K. , Grabarczyk A. , Dobosz St.M. 
Published: December 2016

Abstract
Growing emission requirements are forcing the foundry industry to seek new, more environmentally friendly solutions. One of the solutions may be the technologies of preparing moulding and core sands using organic biodegradable materials as binders. However, not only environmental requirements grow but also those related to the technological properties of moulding sand. Advancing automation and mechanization of the foundry industry brings new challenges related to the moulding sands. Low elasticity may cause defects during assembly of cores or moulds by the manipulators.
The paper presents the study of flexibility in the room temperature according to new method and resistance to thermal deformation of self-hardening moulding sands with furfuryl resin, containing biodegradable material PCL. The task of the new additive is to reduce the moulding sands harmfulness to the environment and increase its flexibility in the room temperature. The impact of the additive and the effect of the amount of binder on the properties of mentioned moulding sands were analysed. Studies have shown that the use of 5% of PCL does not change the nature of the thermal deformation curve, improves the bending strength of tested moulding mixtures and increases their flexibility at room temperature.

Published: December 2016

Abstract2,4-D is a widely used phenoxy herbicide, potentially toxic to humans and biota. The objective of the present study was to reveal short term sublethal effects of 2,4-D on narrow-clawed freshwater crayfish (Astacus leptodactylus Eschscholtz, 1823), based on histology, total haemocyte counts, selected haemolymph parameters, and oxidative stress parameters. In the laboratory conditions crayfish specimens were exposed to 9 mg L-1of 2,4-D for one week. Experiments were conducted under semi-static conditions in 20 L-capacity aquaria where 10 freshwater crayfish were stocked per aquarium. Exposure (experimental) and control groups were used and the experiments were repeated two times. No mortality and behavioural changes were recorded during the experiments. Total haemocyte counts decreased significantly, while haemolymph glucose levels increased (P<0.05), when compared to the control group. Haemolymph levels of calcium, chloride, sodium, potassium, magnesium, total protein, and lactate did not change. Exposure resulted with increased levels of malondialdehyde (MDA) only in hepatopancreas. However, results of gill FOX assay showed a significant decrease in oxidative stress parameters (P<0.05). MDA levels of gill and abdominal muscle tissues and FOX levels of hepatopancreas and abdominal muscle tissues did not change when compared to the control group. Significant histopathological alterations were observed both in hepatopancreas (multifocal deformations in tubule lumen) and gill tissue (melanisation of gill lamella). Exposure of crayfish even to a sublethal concentration of 2,4-D alters histopathology and lipid peroxidation due to stress. Biomarkers studied here seem to be useful for the assessment of adverse/toxic effects of pesticides on non-target, indicator aquatic organisms.

Published: December 2016

Abstract
Nicotine is a potential inducer of oxidative stress, through which it can damage numerous biological molecules. The aim of our study was to investigate the prooxidative effects of nicotine and protective (additive or synergistic) effects of quercetin and vitamin C in the blood of experimental animals, to determine whether the combination of these antioxidants might be beneficial for clinical purposes. Wistar albino rats were receiving intraperitoneal nicotine injection (0.75 mg kg-1 per day) or saline (control group) or nicotine plus quercetin (40 mg kg-1 per day) and vitamin C (100 mg kg-1 per day) for three consecutive days. On day 4, we determined their blood lipid profile, liver enzymes, oxidative stress parameters, and antioxidative system parameters. Compared to untreated control, nicotine significantly increased total cholesterol, LDLcholesterol, triglycerides, liver enzymes (alanine transaminase, aspartate transaminase, and lactate dehydrogenase) and oxidative stress parameters (superoxide anion, hydrogen peroxide, and lipid peroxide) and decreased HDL-cholesterol, glutathione, and superoxide dismutase/catalase activity. Quercetin + vitamin C reversed these values significantly compared to the nicotine alone group. Our results confirm that nicotine has significant prooxidative effects that may disrupt the redox balance and show that the quercetin + vitamin C combination supports antioxidant defence mechanisms with strong haematoprotective activity against nicotine-induced toxicity. In practical terms, this means that a diet rich in vitamin C and quercetin could prevent nicotine-induced toxicity and could also be useful in the supportive care of people exposed to nicotine.
Ectoine as a promising protective agent in humans and animals
Authors: Bownik Adam , Stępniewska Zofia 
Published: December 2016

Abstract
Ectoine is a compatible water molecule-binding solute (osmoprotectant) produced by several bacterial species in response to osmotic stress and unfavourable environmental conditions. This amino acid derivative can accumulate inside cells at high concentrations without interfering with natural processes and can protect the cell against radiation or osmotic stress. This brief review presents the current state of knowledge about the effects of ectoine on animals and focuses on its practical use for enzyme stabilisation, human skin protection, anti-inflammatory treatment, inhibitory effects in neurodegenerative diseases, and other therapeutic potential in human or veterinary medicine.

Abstract
The objective of this study was to reveal the likely genomic instability in children with chronic kidney disease (CKD) using micronucleus (MN) assay on buccal epithelial cells (BEC). We investigated the frequencies of micronuclei and other nuclear anomalies, such as nuclear buds, binucleated cells, condensed chromatin, and karyorrhectic and pyknotic cells in BEC. Children with CKD were grouped as follows: children in the pre-dialysis (PreD) stage (N=17), children on regular haemodialysis (HD) (N=14), and children who have undergone transplantation (Tx) (N=17). As a control group, twenty age- and gender-matched healthy children were selected. The MN frequency in BEC of all groups of children with CKD was significantly elevated (5- to 7-fold) as compared to the control group (p<0.001). In contrast, the frequencies of nuclear buds were not significantly higher in the study groups compared to the control group. The frequencies of binucleated cells and condensed chromatin cells were significantly higher in all subgroups of children with CKD relative to the control group (p<0.001). Our results show that the BEC of pediatric PreD, HD, and Tx patients with CKD display increased cytogenetic, cytokinetic, and cytotoxic effects. They also point to the sensitivity and usefulness of the BEC MN assay in the assessment of genetic susceptibility of patients with CKD.
Air sampling by pumping through a filter: effects of air flow rate, concentration, and decay of airborne substances
Authors: Šoštarić Marko , Petrinec Branko , Babić Dinko 
Published: December 2016

AbstractThis paper tackles the issue of interpreting the number of airborne particles adsorbed on a filter through which a certain volume of sampled air has been pumped. This number is equal to the product of the pumped volume and particle concentration in air, but only if the concentration is constant over time and if there is no substance decomposition on the filter during sampling. If this is not the case, one must take into account the inconstancy of the concentration and the decay law for a given substance, which is complicated even further if the flow rate through the filter is not constant. In this paper, we develop a formalism which considers all of these factors, resulting in a single, compact expression of general applicability. The use of this expression is exemplified by addressing a case of sampling airborne radioactive matter, where the decay law is already well known. This law is combined with three experimentally observed time dependence of the flow rate and two models for the time dependence of the particle concentration. We also discuss the implications of these calculations for certain other situations of interest to environmental studies.

Published: December 2016

Abstract
The effects of cell suspension-alginate ratios, sodium erythorbate, and inulin on encapsulation yield of microcapsules of Bifidobacterium bifidum BB01 were studied by Box-Behnken design. The experimental results indicated that cell suspension-alginate ratios, sodium erythorbate and inulin had a significant impact on encapsulation yield, and the embedding yield could be enhanced significantly in the condition of 1:3 cell suspension-alginate ratios, 0.12% sodium erythorbate, and 6% inulin. The optimal embedding yields of microencapsulation of B. bifidum BB01 were observed to be 81.52%, that values were very close to the expected values 81.81%, so the method was effective.
A Study of Food Enterprises’ Awareness and Behaviors for Social Responsibility
Authors: Zhang Weimei 
Published: December 2016

Abstract
This study is undertaken to evaluate and promote the Chinese food enterprises’ awareness and behaviors for social responsibility. In the survey, the researcher releases 500 copies of questionnaire to the senior managers in Chinese food enterprises. After excluding invalid respondents, the researcher gets 376 valid copies. Then the researcher conducts a descriptive statistical and factor analysis to the copies of questionnaire. The result shows that: firstly, Chinese food enterprises’ awareness of social responsibility is relatively poor; secondly, the majority of food enterprises fulfill their social responsibility passively. Based on the above conclusions, this paper proposes four paths to promote Chinese food enterprises to fulfill social responsibility better, i.e. establish the belief in social responsibility, expand the intensification of food business, make best use of the industrial association and strengthen the government supervision and regulation.
Non-Linearity and Non-Stationarity of Exchange Rate Time Series in Three Central-Eastern European Countries Regarding the CHF Currency in 2014 and 2015
Authors: Madaras Szilárd , Györfy Lehel 
Published: December 2016

Abstract
Our paper deals with the consequences of the Swiss National Bank’s decision in January 2015 related to the CHF/EUR exchange rate regarding the non-linearity of the RON/CHF, HUF/CHF, and PLN/CHF exchange rate time series. The analysis focuses on the 2014 and 2015 years, respectively, using the daily data of the three national banks. Starting out from the conventional unit root tests (ADF, PP, and KPSS), we complete our analysis with the usage of the Threshold Autoregression model (TAR) recommended by Caner and Hansen (2001), testing the non-stationarity and nonlinearity.
Conflicting Narrative Identity Formation in Racialized Intercultural Discourse Nadine Gordimer’sThe Conservationist– A Cognitive Narratological Approach
Authors: Abádi-Nagy Zoltán 
Published: December 2016

AbstractThe paper addresses the issue of how racialized intercultural relations can problematize the formation of narrative identity. How it can call in question the narratability of racialized subjectivity and lead to conflicting narrative identites of the same character as inferrible from narratorial discourse, vis-à-vis the way the character views itself in its intramental activity. And how all of this follows from, and is traceable through the manifestations of, racialized cognitive architecture, and thus, paradoxically, unnarratability can become the source of narrativity. The conflicting nature of racialized subjectivity and narrative identity formation will be examined, then, through a socio-cognitive lens. This study will draw on Nadine Gordimer’s apartheid-era novel, The Conservationist (1974) as a tutor text and will be informed especially by colonial/postcolonial theory, cultural as well as cognitive narratology, cognitive cultural studies, theories of intercultural communication, and discourse analysis.
Narrative Discourse, Memory and the Experience of Travel in W. G. Sebald’sVertigo
Authors: Pieldner Judit 
Published: December 2016

AbstractSebald’s first prose work, entitledVertigo(Schwindel. Gefühle, 1990) is perhaps the most intriguing in terms of the absence of clear-cut links between the four narrative segments: “Beyle; or Love is a Madness Most Discrete,” “All’estero,” “Dr. K Takes the Waters at Riva” and “Il ritorno in patria.” Beyle, i.e. Stendhal, Dr. K, i.e. Kafka, and the first-person narrator of the two quasi-autobiographical parts, are three subjects living in distinct times and places, whose journeys and experiences coalesce into a Sebaldian puzzle to solve, challenging the most varied interpretive terms and discourses, from the Freudian uncanny, through intertextuality (Kristeva) and the indexicality of photography (Barthes, Sontag), to the working of cultural memory (Assmann) and the non-places of what Marc Augé calls hypermodernity. By trying to disclose the discursive strategies of a profoundly elusive and highly complex narrative, the article is aimed at pointing out the rhetorical and textual connections lying at the heart of Sebald’s floating way of writing, heralding a vertiginous oeuvre, an unsettling literary journey.1

Model of multiple-layer pavement structure-subsoil system
Authors: Kadela M. 
Published: December 2016

Abstract
Progress made in recent years has brought about a high demand for increasingly modern structural and technological solutions. Each structure should in turn be designed and built to show sufficient durability for the intended period of use. The requirement of durability is met if, throughout its intended lifetime, the structure fulfils its roles regarding load-bearing capacity, serviceability limits and stability without excessive, unexpected costs. Due to the above, a need arises to predict the response of an engineering structure to given loads throughout its life. Thus it becomes increasingly common to employ numerical analyses using the finite elements method (FEM), both on the design stage and later, for the purposes of evaluating the state of a specific structure. However, a numerical calculation model may be constructed in different ways. This paper presents the impact of geometry of the model, the choice of a discretization mesh and the choice of a continuous 3D or 2D model corresponding to pavement-subgrade system calculation model. 3-dimensional modelling was carried out in this paper as full modelling of actual engineering problems in 3-dimensional space, and in the form of simplified modelling using axial symmetry. In the model, a traditional multi-layer pavement structure was considered. Criterion values obtained in numerical analyses were compared to values obtained with the use of VEROAD software.
Variations by generalized symmetries of local Noether strong currents equivalent to global canonical Noether currents
Authors: Palese Marcella 
Published: December 2016

Abstract
We will pose the inverse problem question within the Krupka variational sequence framework. In particular, the interplay of inverse problems with symmetry and invariance properties will be exploited considering that the cohomology class of the variational Lie derivative of an equivalence class of forms, closed in the variational sequence, is trivial. We will focalize on the case of symmetries of globally defined field equations which are only locally variational and prove that variations of local Noether strong currents are variationally equivalent to global canonical Noether currents. Variations, taken to be generalized symmetries and also belonging to the kernel of the second variational derivative of the local problem, generate canonical Noether currents - associated with variations of local Lagrangians - which in particular turn out to be conserved along any section. We also characterize the variation of the canonical Noether currents associated with a local variational problem.
Towards critical aspects of Confucianism
Authors: Dunaj Ľubomír 
Published: December 2016

AbstractThis paper consists of two parts. The first deals with the issue of whether it is possible to coherently employ the term ‘critical Confucian’ in general, i.e. whether it is a paradox or oxymoron. It will be argued that Confucianism should not be identified with any particular ideology and, therefore, can be critical. This critical potential, in turn, can be developed by bringing it into dialogue with Critical Theory. As such, the second part indicates, in an introductory way, some possible overlaps between Confucianism and Critical Theory by comparing Heiner Roetz’s and Axel Honneth’s respective interpretations of these traditions.
