Published: March 2021

Maintenance management is connected with two opposing aspects, management costs and operational efficiency. With the implementation of new technology within the Industry 4.0 (I4.0) concept, new technical solutions are being created. These solutions (mainly robotic workplaces) must reach a maximum performance rate, production quality, and, of course, high availability. Their operation, during the whole life cycle, is expected to be absolutely safe with minimum maintenance costs. These trends, even though they seem to be optimistic, face a lot of problems. The conducted research follows up on the results of previous research aimed at the initial assessment Slovak industrial company readiness status for the I4.0 conception between 2017 and 2019. The aim of the ongoing research was to assess the readiness status in more than 70 industrial organizations in the selected area for the new concept of maintenance management (eMaintenance) and its relation to machinery integrated safety. The research was carried out by questioning, with the structure of individual questions and closed answers stemmed from the self-evaluation according to the new European Foundation for Quality Management (EFQM) Excellence Model (2020). The results of the research were presented to managements of questioned organizations and confirmed the assumptions about a low level of maintenance management transformation to eMaintenance.
Applying Roadmapping and Conceptual Modeling to the Energy Transition: A Local Case Study
Authors: Muller Gerrit
Published: March 2021

The climate crisis requires a global transition toward sustainable practices. In this transition, policy makers face the challenge to take along a wide variety of stakeholders with own interests, needs, and concerns. This research explores the combined use of conceptual models and roadmapping to facilitate understanding, communication, reasoning, and decision-making between a large heterogeneous set of stakeholders. We apply these methods, in the form of action research, in several smaller research projects at a small town in the Netherlands. We find that the combination of conceptual modeling and roadmapping facilitates discussions between heterogeneous stakeholders on complex transition problems, such as the energy transition, at a local scale. However, we see a significant gap in the way of thinking and communicating between experts and decision-makers, which requires additional means to connect them.

Published: March 2021

The objective of this research was to look into the self-reported food consumption and wastage behavior in Brazil during the COVID-19 pandemic outbreak and the motivations to prevent this waste. The data were collected during the COVID-19 pandemic outbreak in Brazil, May 2020, using a self-administered questionnaire with 60 questions on food consumption behavior and characterization of food waste behaviors. The target audience comprised Brazilian residents responsible for household food purchases; out of 489 responses, 458 were considered valid. The main findings reported that regarding consumption behavior, there are no significant differences in relation to gender, education, and age. The surveyed population preferred shopping in person, despite the recommendation of social distancing, and reported activities to avoid food waste. This behavior suggests the importance of information and consumers’ education in making purchases and reducing waste, mainly amidst a crisis. The results suggest that intention to reduce waste, routines of food purchase in sales and management routines of leftovers or uneaten food are positively related to reducing the economic value of food waste. As a practical contribution, this study expands the understanding in one Latin American country regarding food consumption and wastage. The theoretical contribution leads to understanding of the behavior in times of crisis such as a pandemic.

Published: March 2021

In recent years, black soil has decreased and degenerated heavily due to complicated functions of natural and artificial factors. Hence, characterizing distributions of particle sizes in black soil and their environmental influencing factors is important for understanding black soil degradation. A total of 116 surface soil samples in the top 20 cm from a typical black soil region in northeastern China were collected, and the spatial distribution of particle size parameters were characterized. Particle size-sensitive components were extracted quantitatively using the log-normal distribution function, and their environmental implications were investigated. The contents of black soil mechanical composition ranged from 7.8% to 79.3% for clay, 17.7% to 80.3% for silt, and 0% to 73.7% for sand, respectively. Median particle size ranged from 1.71 to 142.67 μm, with a coefficient of variation of 60%, indicating silt accounted for the majority of the composition. Four environmentally sensitive components were identified, including long-distance transported airborne deposits of clay dust (C1), successions from local parent materials (C2), short-distance deposits of silt particles (C3), and a component strongly disturbed by human activities (C4). C1 and C2 had relatively low variations, with C1 exhibiting the smallest variation, and C2 contributing highest proportion, showing no significant differences across all samples. C3 widely existed across samples, suggesting common wind erosion within the black soil region. C3 and C4 varied spatially, which was caused by the low vegetation coverage and high human disturbance of agricultural topsoil. The results suggest that windbreaks should be encouraged to reduce wind erosion in the black soil regions.
A Lean Approach to Developing Sustainable Supply Chains
Authors: Gargalo Carina L. , Pereda Pons Eduardo , Barbosa-Povoa Ana Paula , Carvalho Ana
Published: March 2021

Corporations and their supply chains have to go through significant changes to become more sustainable as society is pressing for sustainable systems. To this end, it is critical to develop new methodologies to trim away processes and activities that add no value and, thus, derive more sustainable supply chains. Considering the need to have a simple tool that can be used by managers to achieve this goal, in this work, we explore the value stream mapping method (VSM) and extend it to support the design of sustainable supply chains in a more systematic and quantitative way. This work proposes a new generic methodology, called SustainSC-VSM, which allows assessing the supply chain’s performance through a set of realistic indicators. These indicators are designed to identify bottlenecks that hinder sustainable operations development and provide guidelines to achieve that goal by following a lean-driven sustainability approach. SustainSC-VSM was tested and validated through its application to a relevant industrial case study, where operational bottlenecks were pinpointed and potential solutions were identified to seek continuous improvement. Although envisioned to be generic and applicable to all supply chains, the indicators should be selected according to the context in study (e.g., services). SustainSC-VSM aims at being a generic and systematic tool to design future value stream maps to achieve a more sustainable supply chain following a lean-driven sustainability approach, through the use of multi-dimensional and multi-disciplinary indicators to identify and solve the supply chain’s bottlenecks.

Published: March 2021

Biomass can be envisaged as a potential solution to mitigate the problems that the extensive exploitation of fossil sources causes on the environment. Transforming biomass into added-value products with better calorific properties is highly desired. Thermochemical liquefaction can convert biomass into a bio-oil. The work herein presented concerns the study of direct liquefaction of Eucalyptus globulus sawdust. The main goal was to optimise the operating conditions of the process to achieve high bio-oil conversion rates. Studies were carried out to understand the impact of the process factors, such as the residence time, catalyst concentration, temperature, and the biomass-to-solvent ratio. The E. globulus sawdust conversion into bio-oil was achieved with a maximum conversion of 96.2%. A higher conversion was reached when the eucalyptus sawdust’s thermochemical liquefaction was conducted over 180 min in the presence of a >2.44% catalyst concentration at 160 °C. A lower biomass-to-solvent ratio favours the process leading to a higher conversion of biomass into bio-oil. The afforded bio-oil presented a better higher heating value than that of E. globulus sawdust.
Towards a Sustainable News Business: Understanding Readers’ Perceptions of Algorithm-Generated News Based on Cultural Conditioning
Authors: Kim Yunju , Lee Heejun
Published: March 2021

The use of algorithms is beginning to replace human activities in the news business, and the presence of this technique will only continue to grow. The ways in which public news readers perceive the quality of news articles written by algorithms and how this perception differs based on cultural conditioning remain issues of debate. Informed by the heuristic-systematic model (HSM) and the similarity-attraction theory, we attempted to answer these questions by conducting a three-way one-way analysis of variance (ANOVA) test with a 2 (author: algorithm vs. human journalist) × 2 (media: traditional media vs. online media) × 2 (cultural background: the US vs. South Korea) between-subjects experiment (N = 360). Our findings revealed that participants perceived the quality of news articles written by algorithms to be higher than those written by human journalists. We also found that when news consumption occurs online, algorithm-generated news tends to be rated higher than human-written news in terms of quality perception. Further, we identified a three-way interaction effect of media types, authors, and cultural backgrounds on the quality perception of news articles. As, to the best of our knowledge, this study is the first to theoretically examine how news readers perceive algorithm-generated news from a cultural point of view, our research findings may hold important theoretical and practical implications.
Agency Barriers of the Members of Silesian Senior NGOs in the Implementation of Social Innovation (Poland)
Authors: Weryński Piotr , Dolińska-Weryńska Dorota
Published: March 2021

One of the main barriers when implementing social innovation deemed to be significant is the agency barrier. The purpose of this research is to diagnose the structurally conditioned and awareness agency barriers that occur during the implementation of social innovation in the selected Silesian senior non-governmental organizations. It was assumed that, these days, an important parameter in determining agency is the digital competence possessed. Therefore, it is important to ascertain the level of digital competence of the examined non-governmental organization (NGO) leaders and members as the prosumers of social innovation, which determines the course of their innovative activities. The theoretical basis of research is Margaret Archer’s morphogenetic theory of structure and agency and her scheme of causal analysis. On this basis and using a qualitative analysis of data obtained during focus group interviews (FGIs) and computer-assisted web interviews (CAWIs) with the members of NGOs, a diagnosis is conducted concerning the occurrence of agency barriers in the processes of social innovation. It was found that the majority of respondents have the agency potential, knowledge, and competence to actively co-create Society 5.0. The obtained research results will allow educational and implementation projects (action research) to be carried out in the future that are adequate to the needs of this particular social group. At the theoretical level, the usefulness of the morphogenetic scheme was verified in a causal analysis to study the social agency of the members of senior NGOs.
Entity Relation Extraction Based on Entity Indicators
Authors: Qin Yongbin , Yang Weizhe , Wang Kai , Huang Ruizhang , Tian Feng , Ao Shaolin , Chen Yanping
Published: March 2021

Relation extraction aims to extract semantic relationships between two specified named entities in a sentence. Because a sentence often contains several named entity pairs, a neural network is easily bewildered when learning a relation representation without position and semantic information about the considered entity pair. In this paper, instead of learning an abstract representation from raw inputs, task-related entity indicators are designed to enable a deep neural network to concentrate on the task-relevant information. By implanting entity indicators into a relation instance, the neural network is effective for encoding syntactic and semantic information about a relation instance. Organized, structured and unified entity indicators can make the similarity between sentences that possess the same or similar entity pair and the internal symmetry of one sentence more obviously. In the experiment, a systemic analysis was conducted to evaluate the impact of entity indicators on relation extraction. This method has achieved state-of-the-art performance, exceeding the compared methods by more than 3.7%, 5.0% and 11.2% in F1 score on the ACE Chinese corpus, ACE English corpus and Chinese literature text corpus, respectively.
Mathematical Model for Cargo Allocation Problem in Synchromodal Transportation
Authors: Batarlienė Nijolė , Šakalys Raimondas
Published: March 2021

Synchromodality is a freight transport process in which information is exchanged expeditiously in order to maximize the benefits of different modes of transport and transport nodes in terms of efficiency and environmental impact. The aim of the study is to analyze the problems of synchronized intermodal traffic management between the main port and inland transport nodes in European transport corridors and to find reliable solutions to these problems. Therefore, the main purpose of this article is to investigate the problem of the distribution of containers transported by rail between two transport terminals in a synchronous transport network. A specific optimization model is presented in this article. This optimization task is formulated as a stochastic integer programming model between the terminals located in Vilnius and Klaipeda Seaport, the essence of which is as follows: (a) to minimize the waiting time for container cargo at the location—terminal No. 1; (b) to minimize the total journey time of the train; (c) to minimize the waiting time for containerized cargo at the point of arrival—terminal No. 2.

Published: March 2021

2-(2-Fluoro-4-biphenyl) propionic acid (flurbiprofen), from the phenylalkanoic acid family of nonsteroidal anti-inflammatory drugs (NSAID’s), is currently on the pharmaceutical market as a racemate. This racemic compound was tested for its propensity to undergo the self-disproportionation of enantiomers (SDE) phenomenon by various forms of chromatography (SDEvC), such as routine gravity-driven column chromatography, medium-pressure liquid chromatography (MPLC), preparative thin-layer chromatography (PTLC), and size-exclusion chromatography (SEC), as well as by sublimation (SDEvS). Furthermore, examination by nuclear magnetic resonance (NMR) in various solvents found that flurbiprofen exhibited the phenomenon of self-induced diastereomeric anisochronism (SIDA). By measurement of the diffusion coefficient (D), the longitudinal relaxation time (T1), and the transverse relaxation time (T2) using NMR, as well as by electrospray ionization-mass spectrometry (ESI-MS) examinations, the preferred intermolecular association was found to be solvent dependent, e.g., heterochiral association was preferred in toluene, while homochiral association was preferred in more polar solvents. This study also attempted, unsuccessfully, to correlate the NMR measurements of flurbiprofen with chromatographic outcomes for the rationalization and prediction of chromatographic results based on NMR measurements. Because the intermolecular hydrogen bonding of the acid groups in flurbiprofen overwhelmingly predominates over other intermolecular interactions, flurbiprofen seemed to represent a good test case for this idea. The behavior of scalemic samples of flurbiprofen is important, as, although it is currently dispensed as a racemate, clinical applications of the R enantiomer have been investigated. SDEvC and SDEvS both have ramifications for the preparation, handling, and storage of enantioenriched flurbiprofen, and this concern applies to other chiral drugs as well.
Fernandez–Steel Skew Normal Conditional Autoregressive (FSSN CAR) Model in Stan for Spatial Data
Authors: Rantini Dwi , Iriawan Nur , Irhamah
Published: March 2021

In spatial data analysis, the prior conditional autoregressive (CAR) model is used to express the spatial dependence on random effects from adjacent regions. This paper provides a new proposed approach regarding the development of the existing normal CAR model into a more flexible, Fernandez–Steel skew normal (FSSN) CAR model. This approach is able to capture spatial random effects that have both symmetrical and asymmetrical patterns. The FSSN CAR model is built on the basis of the normal CAR with an additional skew parameter. The FSSN distribution is able to provide good estimates for symmetry with heavy- or light-tailed and skewed-right and skewed-left data. The effects of this approach are demonstrated by establishing the FSSN distribution and FSSN CAR model in spatial data using Stan language. On the basis of the plot of the estimation results and histogram of the model error, the FSSN CAR model was shown to behave better than both models without a spatial effect and with the normal CAR model. Moreover, the smallest widely applicable information criterion (WAIC) and leave-one-out (LOO) statistical values also validate the model, as FSSN CAR is shown to be the best model used.

Published: March 2021

Bee venom is a complex mixture composed of peptides, proteins with enzymatic properties, and low-molecular-weight compounds. Although the carboxylesterase in bee venom has been identified as an allergen, the enzyme’s role as a venom component has not been previously elucidated. Here, we show the lipolytic activity of a bumblebee (Bombus ignitus) venom carboxylesterase (BivCaE). The presence of BivCaE in the venom secreted by B. ignitus worker bees was confirmed using an anti-BivCaE antibody raised against a recombinant BivCaE protein produced in baculovirus-infected insect cells. The enzymatic activity of the recombinant BivCaE protein was optimal at 40 °C and pH 8.5. Recombinant BivCaE protein degrades triglycerides and exhibits high lipolytic activity toward long-chain triglycerides, defining the role of BivCaE as a lipolytic agent. Bee venom phospholipase A2 binds to mammalian cells and induces apoptosis, whereas BivCaE does not affect mammalian cells. Collectively, our data demonstrate that BivCaE functions as a lipolytic agent in bee venom, suggesting that BivCaE will be involved in distributing the venom via degradation of blood triglycerides.
CDT Quantum Toroidal Spacetimes: An Overview
Authors: Ambjorn Jan , Drogosz Zbigniew , Gizbert-Studnicki Jakub , Görlich Andrzej , Jurkiewicz Jerzy , Németh Dániel
Published: March 2021

Lattice formulations of gravity can be used to study non-perturbative aspects of quantum gravity. Causal Dynamical Triangulations (CDT) is a lattice model of gravity that has been used in this way. It has a built-in time foliation but is coordinate-independent in the spatial directions. The higher-order phase transitions observed in the model may be used to define a continuum limit of the lattice theory. Some aspects of the transitions are better studied when the topology of space is toroidal rather than spherical. In addition, a toroidal spatial topology allows us to understand more easily the nature of typical quantum fluctuations of the geometry. In particular, this topology makes it possible to use massless scalar fields that are solutions to Laplace’s equation with special boundary conditions as coordinates that capture the fractal structure of the quantum geometry. When such scalar fields are included as dynamical fields in the path integral, they can have a dramatic effect on the geometry.

Published: March 2021

The use of polyhydroxyalkanoates (PHA) as slow-release electron donors for environmental remediation represents a novel and appealing application that is attracting considerable attention in the scientific community. In this context, here, the fermentation pattern of different types of PHA-based materials has been investigated in batch and continuous-flow experiments. Along with commercially available materials, produced from axenic microbial cultures, PHA produced at pilot scale by mixed microbial cultures (MMC) using waste feedstock have been also tested. As a main finding, a rapid onset of volatile fatty acids (VFA) production was observed with a low-purity MMC-deriving material, consisting of microbial cells containing 56% (on weight basis) of intracellular PHA. Indeed, with this material a sustained, long-term production of organic acids (i.e., acetic, propionic, and butyric acids) was observed. In addition, the obtained yield of conversion into acids (up to 70% gVFA/gPHA) was higher than that obtained with the other tested materials, made of extracted and purified PHA. These results clearly suggest the possibility to directly use the PHA-rich cells deriving from the MMC production process, with no need of extraction and purification procedures, as a sustainable and effective carbon source bringing remarkable advantages from an economic and environmental point of view.

Evaluation of the Ecological Potential of Microorganisms for Purifying Water with High Iron Content
Authors: Pleshakova Ekaterina , Ngun Clement , Reshetnikov Mikhail , Larionov Maxim Viktorovich
Published: March 2021

The ability of a number of microorganisms isolated from highly magnetic soil of the city Mednogorsk to oxidize Fe (II) under conditions of periodic cultivation in a liquid medium was studied. Among the studied microorganisms, two microbial isolates with maximum growth characteristics and iron-oxidizing activity were selected and identified: Bacillus megaterium 69.3 and B. megaterium 69.5. Individual levels of metal resistance of the isolates were determined: maximum tolerated concentration (MTC) for Fe (II) of the isolates B. megaterium 69.3 and B. megaterium 69.5 was 1200 mg L−1, minimum inhibitory concentration (MIC) was 1800 mg L−1. Both microbial isolates actively oxidized Fe (II) by reducing its high concentration in the medium (1.19 g L−1) by 33 and 39% during 14 days of culturing. Total increase in the biomass of B. megaterium 69.3 and B. megaterium 69.5 after 14 days of culturing was 15.3 and 14.7 g L−1; the active parts of the biomass increased 8.7- and 6.9-fold compared to the inoculum dose, respectively. These microbial isolates could be used in future in the biotechnological process of water purification with increased/high levels of Fe (II).
Revisiting Surface-Subsurface Exchange at Intertidal Zone with a Coupled 2D Hydrodynamic and 3D Variably-Saturated Groundwater Model
Authors: Li Zhi , Hodges Ben R.
Published: March 2021

A new high-performance numerical model (Frehg) is developed to simulate water flow in shallow coastal wetlands. Frehg solves the 2D depth-integrated, hydrostatic, Navier–Stokes equations (i.e., shallow-water equations) in the surface domain and the 3D variably-saturated Richards equation in the subsurface domain. The two domains are asynchronously coupled to model surface-subsurface exchange. The Frehg model is applied to evaluate model sensitivity to a variety of simplifications that are commonly adopted for shallow wetland models, especially the use of the diffusive wave approximation in place of the traditional Saint-Venant equations for surface flow. The results suggest that a dynamic model for momentum is preferred over diffusive wave model for shallow coastal wetlands and marshes because the latter fails to capture flow unsteadiness. Under the combined effects of evaporation and wetting/drying, using diffusive wave model leads to discrepancies in modeled surface-subsurface exchange flux in the intertidal zone where strong exchange processes occur. It indicates shallow wetland models should be built with (i) dynamic surface flow equations that capture the timing of inundation, (ii) complex topographic features that render accurate spatial extent of inundation, and (iii) variably-saturated subsurface flow solver that is capable of modeling moisture change in the subsurface due to evaporation and infiltration.
Water Security and River Basin Revitalization of the São Francisco River Basin: A Symbiotic Relationship
Authors: Alves da Silva Rosa Larissa , Morais Manuela , Saito Carlos
Published: March 2021

What is river basin revitalization’s place in relation to water security? This question is the basis of our reflection, posed to help in the understanding of the evolution of both concepts, taking management of the São Francisco River Basin (Brazil) as a case study. With this main objective in mind, a literature review was carried out, followed by the collection of survey data on the watershed’s revitalization program. In this context, the members of the São Francisco River Basin Committee (a total of 124 participants) were consulted, using questionnaires with the Delphi method. The respondents (a total of 47) chose the river basin revitalization strategy as the main measure to achieving water security in the São Francisco River Basin. They also highlighted the importance of the environmental dimension, underlining measures for conservation and restoration of the ecosystem’s natural functions. The concept map tool was adopted for a comparative perspective between conceptual implications of revitalization and water security for the studied river basin’s conservation. The results showed the existence of a symbiotic relationship between both concepts. Consequently, we conclude that it is urgent to reconcile water use and ecosystem ecological integrity through the comprehensive concept of water security.
PIV Study on Grid-Generated Turbulence in a Free Surface Flow
Authors: Yao Haoyu , Cao Linlin , Wu Dazhuan , Gao Yangyang , Qin Shijie , Yu Faxin
Published: March 2021

To investigate the feature of turbulence developing behind the filter device in a current flow, the flow fields at intermediate downstream distance of an immersed grid in an open water channel are recorded using a two-dimensional (2D) Particle Image Velocimetry (PIV) system. The measurements on a series of vertical and horizontal sections are conducted to reveal the stream-wise evolution and depth diversity of grid turbulence in the free surface flow. Unlike the previous experiments by Laser Doppler Velocimetry (LDV) and Hot-Wire Anemometry (HWA), the integral scales and space-time correlations are estimated without using the Taylor hypothesis in this paper. The distributions of mean velocity, turbulence intensity and integral scale show the transition behavior of grid-generated flow from perturbations to fully merged homogenous turbulence. The distributions of velocity and turbulence intensity become more uniform with increasing distance. While the spatial divergence of integral scale becomes more pronounced as the flow structures develop downstream. The vertical distributions of flow parameters reveal the diversity of flow characteristics in the water depth direction influenced by free surface and the outer part of turbulence boundary layer (TBL) from the channel bottom. The applicability of the newly proposed two-order elliptic approximation model for the space-time correlations of the decaying grid turbulence in channel flow is verified at different positions. The calculated convection velocity for large-scale motion and sweep velocity for small-scale motion based on this model bring a new insight into the dynamic pattern of this type of flow.
Dissociative identity disorder: a look at the role of life history coherence
Authors: Pedros Marie-Michelle
Published: March 2021

During the last several decades, many theories have tried to explain dissociative identity disorder (DID). Currently, the post-traumatic model (Davison, Blankstein, Flett, & Neale, 2008) is most commonly used by scientists to explain this disorder. The main hypothesis of this model states that a person who has endured multiple severe traumas in his or her childhood is more inclined to develop DID. However, this model does not answer a critical question: how can we explain why, of the many people who experience similar trauma, some develop DID and some do not? The present article suggests an alternate model, an integrative model of DID that combines the coherent life story hypothesis with the post-traumatic model. This new model suggests that because of genetic vulnerability, a person with an incoherent life story due to non-integration of traumatic events would develop DID.
The role of self-complexity in the motivation to reveal a stigmatized identity
Authors: Bergeron Catherine
Published: March 2021

Being a member of a devalued social group can be difficult to bear. For some, it is difficult to openly reveal one’s membership in this type of group. Refraining from revealing this important aspect of one’s identity can lead to negative consequences for one’s well-being. What distinguishes those who reveal their membership in a devalued group from those who do not? This article presents an integrated theoretical model that explains the role of self-complexity, perceived social stigmatization, and the motivation to disclose one’s membership in a devalued group. This model adds a new perspective by identifying individual factors that lead to the revelation of a stigmatized identity.
Resolving the Unique Situation: Consequences for Identity and Psychological Well-Being
Authors: French Bourgeois Laura
Published: March 2021

Teen pregnancy regularly brings about numerous changes in the life of the young mother. The most salient problem for teenage mothers, for example, is the lack of a supportive community. First, we will attempt to explain how little support from a community can lead to low levels of well-being. Secondly, we suggest solutions to overcome this problem. We propose that the young mothers perceive their situation as a Unique Situation. We advance the idea that the perception of living through a Unique Situation brings the young mothers to compare their situation to the one before their pregnancy, resulting in a decrease in well-being. This paper theorizes that by sharing a Unique Situation with others living through a similar situation, social comparisons will become available and consequently higher levels of well-being will be experienced.
Temporal comparisons and relative temporal deprivation as causes of identity conflict and foreclosed identity
Authors: Thisdale Cynthia
Published: March 2021

The teenage years are known to be full of changes requiring the individual to adapt to the new facetsof the self. Although this adaptation differs from one person to another, it requires a reorganization of social roles and consequently a reorganization of the self. One question that often plagues teenagers is: what happens to the identity of a young teenager when an unplanned pregnancy occurs? This article, based on a review of literature, attempts to better understand the source of a dual identity conflict of two or more opposing and contradictory identities, when someone is facing a sudden and unexpected event. The example of teens as future parents will be used throughout the manuscript in order to support the proposed ideas. This manuscript also attempts to propose solutions to help resolve the dual conflicting identities that many teens struggle with when they face such situations.

According to the register, Kharkiv cimbalom school is the youngest, but at the same time one of the most progressive performing schools in Ukraine. Conclusions. It is shown that for thirty years of existence of the cimbalom class of KhNUA the idea of professional training at three educational levels – from music school to institution of higher education has been successfully realized. Many laureates of international, all-Ukrainian and regional competitions, festivals, graduates of the class are brought up. The high level of instrumental, performing, professional training is distinguished. At the same time, the development of the academic direction in performance on folk instruments, in particular on cimbalom, has significantly broaden the boundaries of the traditional folk instrumental genre. It is shown that the formation of the cymbal class in KhNUA during the 30 years of its existence completed the formation of the Kharkiv cimbalom school, and its future will be improved and filled with new victories and ideas at a new, more advanced level.

Various inorganic acid doped PMMA/PANI composite are prepared by in-situ polymerization technique. Morphology, room temperature (RT) conductivity and DC-conductivity with temperature variation (77-300 K) are analyzed by scanning electron microscopy (SEM) and linear four probe technique, respectively. Fibril structures with different diameter are observed in doped PMMA/PANI composite, whereas smooth texture is found in PMMA polymer film. Room temperature DC conductivity is found 0.1497 × 10-2 S/cm for H2SO4-and 0.309 × 10-3 S/cm for H3PO4-, 0.244 × 10-3S/cm for HCl-doped conductive composite, respectively. Temperature dependent DC Conductivity is measured and it behaves like semiconductor.

Апстракт: Тема рада је унапређење сточарства у Краљевини Србији селекцијом, укрштањем и увођењем нових сојева. Утврђивању и спровођењу посебних мера у области сточарства претходио је период у коме је долазило до спорадичног увоза страних сојева различитих врста домаћих животиња и непланираног укрштања са домаћим. Крајем 19. и почетком 20. века постављени су темељи политике која ће бити настављена и у каснијем периоду а чији ће главни циљ бити висока продуктивност, пре свега меса и млека. Наставак и успешност спровођења те политике у каснијем периоду довела је до смањења броја грла аутохтоних раса, којима је данас потребна заштита у циљу очувања биодиверзитета. Кључне речи: сточарство, државне политике, Србија, биодиверзитет, селекција, укрштање, расе
