Microphytobenthos as an indicator of water quality and organic pollution in the western coastal zone of the Sea of Azov
Authors: Barinova Sophia , Bondarenko Anna , Ryabushko Larisa , Kapranov Sergey 
Published: June 2019

Abstract
Bioindication of organic pollution and seawater quality was carried out for the first time in the western part of the Sea of Azov on the basis of species composition and quantitative characteristics of microphytobenthos. A total of 229 algal samples were collected at 17 sites over the period of 2005-2014 on three different substrates in three areas under study: Sivash Gulf, the Kerch Strait and Cape Kazantip. In total, 200 taxa of algae were found, which belong to six taxonomic divisions with a predominance of diatoms. Among those, 108 taxa are indicators of substrate, water temperature, salinity, water pH, trophic state, the type of nutrition and organic pollution of water. It has been shown that the most active self-purification of water takes place in communities on stony substrates. The largest number of algae species (50%) occurs in the cleanest waters of the Kazantip Nature Reserve (Water Quality Classes I–II). The species composition of organic pollution indicators in Sivash Gulf corresponds to waters of Classes III–IV, which are more polluted than those of the Kerch Strait and Cape Kazantip. All the studied areas of the Sea of Azov are cleaner compared to some waters of the Eastern Mediterranean and the Sea of Japan.
On the influence of water on fragmentation of the amino acid L-threonine
Authors: Baliulyte Laura , Tamuliene Jelena 
Published: June 2019

Abstract
The present study describes the fragmentation of the amino acid L-threonine (C4H9NO3) with and without the inclusion of water influence. The fragmentation of the L-threonine molecule was theoretically studied using the Becke’s three-parameter hybrid functional method by applying the non-local correlation provided by Lee, Yang and Parr (B3LYP) with the correlation consistent triple zeta basis (cc-pVTZ). The polarizable continuum model (PCM) was used to evaluate the influence of water. Fragments were selected based on data from mass spectrometry experiments. The chemical compositions of fragments were identified, and the appearance energy was calculated. Based on the obtained results, we can conclude that water affects the appearance energy, the fragment structure and the fragment formation processes.

Published: June 2019

Abstract
Little is still known about the neuroanatomical substrates related to changes in specific cognitive abilities in the course of healthy aging, and the existing evidence is predominantly based on cross-sectional studies. However, to understand the intricate dynamics between developmental changes in brain structure and changes in cognitive ability, longitudinal studies are needed. In the present article, we review the current longitudinal evidence on correlated changes between magnetic resonance imaging-derived measures of brain structure (e.g. gray matter/white matter volume, cortical thickness), and laboratory-based measures of fluid cognitive ability (e.g. intelligence, memory, processing speed) in healthy older adults. To theoretically embed the discussion, we refer to the revised Scaffolding Theory of Aging and Cognition. We found 31 eligible articles, with sample sizes ranging from n = 25 to n = 731 (median n = 104), and participant age ranging from 19 to 103. Several of these studies report positive correlated changes for specific regions and specific cognitive abilities (e.g. between structures of the medial temporal lobe and episodic memory). However, the number of studies presenting converging evidence is small, and the large methodological variability between studies precludes general conclusions. Methodological and theoretical limitations are discussed. Clearly, more empirical evidence is needed to advance the field. Therefore, we provide guidance for future researchers by presenting ideas to stimulate theory and methods for development.

Published: June 2019

Abstract

Objective

Eucalyptus camaldulensis is recognized to be one of the major introduced eucalypts, the plant extracts possess a wide range of phytochemicals, which are accountable for its antioxidant and pharmacological activities. The extraction efficiency of such chemical compounds is influenced by the applied extraction conditions. To test the effect of solvent type on the yield of phenolics and antioxidants from E. camaldulensis, seeking for an optimization of the extraction process.

Method
Dry powders of four plant organs were extracted by some organic solvents besides water. The total phenolic content was detected in the crude extracts of leaf, bud, empty capsule and seed, and was further characterized by GC-MS.

Results
Acetone-water mixtures yielded high amounts of phenolic compounds with parallel antioxidant activities, correlation coefficients were significant (0.696–0.998). Bud and capsule are first accredited for their antioxidant potentials. The GC-MS analysis revealed the abundance of most detected phenolic constituents in the plant seed.

Discussion
Acetone-water is a successful and appropriate mixture for the extraction of phenolic compounds from E. camaldulensis. It could give better yields and enhance the biological activities of its corresponding extracts.

Conclusion
The accurate choice of an extraction solvent has a great influence on the yields of phenolics.
Difficult Women: Changing Representations of Female Characters in Contemporary Television Series
Authors: Hohenstein Svenja , Thalmann Katharina 
Published: June 2019

AbstractStarting out with a brief overview of recent TV series that feature complex and complicated female characters – or, as we call them, ‘difficult women’ – this introduction investigates the changing manner in which women have been represented on TV in previous decades. Demonstrating that especially TV shows of the 2010s undermine and work against traditional and stereotypical portrayals of women on TV and instead establish feminist discourses, we argue that this time period can be defined as a pivotal moment with regard to changing representations of women on TV. Using Netflix’sOrange Is the New Blackas an example, we also show that TV series that feature difficult women make use of the very techniques and conventions of what Jason Mittell has described as ‘Complex TV’ in order to consciously engage with questions of female representation on TV and to create a feminist discourse that works against sexist tropes and stereotypes.
Intransitive verbs in Enets: A contribution to the typology of split intransitivity
Authors: Khanina Olesya , Shluinsky Andrey 
Published: June 2019

Abstract
This paper contributes to the typology of “active-stative” split intransitivity and middle voice with a detailed case study: it proceeds from a typological comparison of the two phenomena, which are usually treated apart, to an analysis of the Enets data and a discussion of its place in the typology of possible intransitive splits. Enets (Uralic, Samoyedic) has two classes of intransitive verbs, and each class uses its own cross-reference paradigm in all finite forms. The paper provides an account of the morphology of this intransitive split and its connection to the lexical aspect, followed by an overview of semantic composition of the two lexical classes; special attention is given to cases of class variation available for a dozen verbs. The research is based on the data of a fieldworkers’ corpus and thus also shows the advantages of a corpus-based approach to this phenomenon.
Grammatical taboos
Authors: Vogel Ralf 
Published: June 2019

Abstract
This explorative study focuses on grammatical taboos in German, morphosyntactic constructions which are subject to stigmatisation, as they regularly occur in standard languages. They are subjected to systematic experimental testing in a questionnaire study with gradient rating scales on two salient and two non-salient grammatical taboo phenomena of German. The study is divided into three subexperiments with different judgement types, an aesthetic judgement, a norm-oriented judgement and the sort of possibility judgement that comes closest to linguists’ understanding of grammar. Included in the investigated material are also examples of ordinary gradient grammaticality: unmarked, marked and ungrammatical sentences. The empirical characteristics of grammatical taboos are compared to those ordinary cases with the finding that they are rated at the level of markedness, but differ from ordinary markedness in that they produce a different pattern of between-subject variance. In addition, we find that grammatical taboos have a particular disadvantage under the aesthetic judgement type. The paper also introduces the concept of empirical grammaticality as a necessary theoretical cornerstone for empirical linguistics. Methodically, the study applies a mix of parametric and non-parametric methods of statistical analysis.
Implicational Complement Coordination and beyond: Towards a coherent theory of asymmetric coordination in German
Authors: Weisser Philipp 
Published: June 2019

AbstractA certain class of predicates in German optionally allows for their complement clause to appear as coordinated with the matrix clause rather than embedded into it. This construction, which I will call Implicational Complement Coordination, exhibits all the hallmark properties of Asymmetric Coordination: Despite technically being in a conjunct position, the clause in question behaves like a subordinate clause with respect to asymmetric binding, asymmetric scope of negation and adverbs as well as asymmetric extraction. Based on the detailed description of the phenomenon by Reis (1993), it can be shown that this coordinate construction mimics its infinitival counterpart with respect to these syntactic tests. In this paper, I argue that this can be accounted for by saying that the coordinate construction is derived on the basis of its subordinate counterpart by means of movement. The subordinate properties of the second conjunct then derive from its derivational history as a subordinate clause. Further, I will show that even though other cases of Asymmetric Coordination (in German) lack a minimally different infinitival counterpart, they can and should still be derived from an underlyingly subordinate syntax.
Impact of water-soluble zwitterionic Zn(II) phthalocyanines against pathogenic bacteria
Authors: Mantareva Vanya , Gol Cem , Kussovski Vesselin , Durmuş Mahmut , Angelov Ivan 
Published: June 2019

Abstract
The photodynamic impact of water-soluble zwitterionic zinc phthalocyanines (ZnPc1–4) was studied on pathogenic bacterial strains after specific light exposure (LED 665 nm). The structural differences between the studied ZnPc1–4 are in the positions and the numbers of substitution groups as well as in the bridging atoms (sulfur or oxygen) between substituents and macrocycle. The three peripherally substituted compounds (ZnPc1–3) are tetra-2-(N-propanesulfonic acid)oxypyridine (ZnPc1), tetra-2-(N-propanesulfonic acid)mercaptopyridine (ZnPc2), and octa-substituted 2-(N-propanesulfonic acid)mercaptopyridine (ZnPc3). The nonperipherally substituted compound is tetra-2-(N-propanesulfonic acid)mercaptopyridine (ZnPc4). The uptake and localization capability are studied on Gram (+) Enterococcus faecalis and Gram (−) Pseudomonas aeruginosa as suspensions and as 48 h biofilms. Relatively high accumulations of ZnPc1–4 show bacteria in suspensions with different cell density. The compounds have complete penetration in E. faecalis biofilms but with nonhomogenous distribution in P. aeruginosa biomass. The cytotoxicity test (Balb/c 3T3 Neutral Red Uptake) with ZnPc1–4 suggests the lack of dark toxicity on normal cells. However, only ZnPc3 has a minimal photocytotoxic effect toward Balb/c 3T3 cells and a comparable high potential in the photoinactivation of pathogenic bacterial species.
Chloride Absorption Behavior of Layered Double Hydroxides in Chloride Environment
Authors: Ma Juntao , Wang Daguang , Chen Hao , Duan Ping , Shi Yanke 
Published: June 2019

Abstract
Chloride penetration is an important factor of concrete durability, whereas chloride ions have the potential to be absorbed by layered double hydroxides (LDHs). Magnesium-aluminum-CO3 LDHs are used in this experiment, and chloride ion absorption in chloride solution and hardened cement paste is studied. Additionally, the chloride penetration behavior in concrete containing raw LDHs and calcined LDHs (CLDHs) is also studied. The results indicate that raw LDHs show lower chloride ion absorption ability and CLDHs can absorb chloride ions in cement paste to reconstruct the structure and reduce the chloride concentration. The addition of CLDHs absorbs the chloride ions in concrete to delay the penetration, which improves the chloride ion resistance of concrete.

Published: June 2019

Abstract
In this study, artificial neural network (ANN) is applied to predict the erosion rate of nylon-12 polymer to ensure the accuracy of soft computing. The ANN model was developed with 4 neurons in the input layer, 10 neurons in the hidden layer, and 1 neuron in the output layer. A backpropagation algorithm was utilized in a multilayered perception. The inputs include impact velocity (m/s), impingement angle (°), erodent size (μm), and stand-off distance (mm). Experimental data were used to predict the erosion rate in relation to the input parameters. The size of the erosive element of randomly shaped sand particles (silicon dioxide) is set between 300 and 600 μm, the impact velocity between 30 and 50 m/s, the impingement angle between 30° and 90°, and the stand-off distance between 15 and 25 mm. The consistency between the experimental and ANN model values, with an accuracy of 94.428 % and root mean square error of 9.729, signifies that the proposed ANN model is suitable for predicting the erosion rate of nylon-12 polymer. The prediction made using the ANN model was in good agreement with the experimental results. The ANN model can be used to estimate the maximum and total erosion rate of nylon-12 with high reliability. Therefore, this model can be applied for practical purposes.

Abstract
Arogyapacha, the local name of Trichopus zeylanicus, is a rare, indigenous medicinal plant of India. This plant is famous for its traditional use as an instant energy stimulant. So far, no genomic resource is available for this important plant and hence its metabolic pathways are poorly understood. Here, we report on a high-quality draft assembly of approximately 713.4 Mb genome of T. zeylanicus, first draft genome from the genus Trichopus. The assembly was generated in a hybrid approach using Illumina short-reads and Pacbio longer-reads. The total assembly comprised of 22601 scaffolds with an N50 value of 433.3 Kb. We predicted 34452 protein coding genes in T. zeylanicus genome and found that a significant portion of these predicted genes were associated with various secondary metabolite biosynthetic pathways. Comparative genome analysis revealed extensive gene collinearity between T. zeylanicus and its closely related plant species. The present genome and annotation data provide an essential resource to speed-up the research on secondary metabolism, breeding and molecular evolution of T. zeylanicus.

STRUCTURAL COMPONENTS OF “HUMAN SECURITY” IN THE CONCEPTUALIZATION OF NATIONAL SECURITY: CASE OF THE REPUBLIC OF ARMENIA
Authors: KARAPETYAN Ruzanna R. 
Published: June 2019

Introduction.The study aims at examining the concept of security from the perspective of a human being as an individual, his/her personal development and chances for the full realization of human potential within the framework of state security. The correlation of the two concepts is the basis upon which we attempt to reveal the extent to which the balance between human and state security is maintained. In the study, we draw upon the example of the Republic of Armenia, its basic national security documents and the specific niche that human security occupies in this context. At this stage we limit the study to the level of documents without referring to the implementation of the basic principles of security reflected in the appropriate documents in real life. Internal changes in the political situation in the country and the fundamental principles underlying and generating these changes call for the necessity of scholarly examination of the concepts in question. The immediate aim of the study is to delineate the concept of “human security” as reflected in the framework of the national security of the Republic of Armenia, namely in the fundamental documents referring to the national securityMethods.Initially in the paper we introduce the theoretical background and expound all those conceptual premises and the definitions of “human security” of various scholars and scholarly schools which precondition the nature of the research. Drawing upon the method of qualitative-quantitative content analysis, we make an attempt to show to which extent the concept of “human security” is conceptualized in the sources mentioned. The following documents served as an empirical material for the study – the Constitution of the Republic of Armenia, Republic of Armenia 2014-2025 Strategic Program of Prospective Development, as well as the National Security Strategy. The representativeness of the material is accounted for by the fact that the state and government are guided act in line with these documents.Results and conclusions.The study permits to conclude that the balance between state security and human security in Armenia is shifted towards the former, with the apparent prevalence of military security sector.

Published: June 2019

It is important to
identify academic procrastination behaviours disrupting the educational life of
students, it is also important to determine the academic procrastination
tendencies and underlying causes in teachers and pre-service teachers, who are
an inseparable part of the education environment. The aim of this research was
to examine several variables of academic procrastination behaviour in a group
of 113 pre-service teachers studying in the Physical Education and Sports
Teaching Department of Anadolu University. The Academic Procrastination
Inventory developed by Aitken (1982) and adapted to Turkish by Balkis (2006)
was used in the study. In the analyses of the data, arithmetic means, standard
deviation, t-test and ANOVA analysis were used. According to the results
obtained, no significant difference was determined between the levels of
academic procrastination of the pre-service teachers according to gender, year
of study, the department selected for study, parental level of education or the
perceptions of academic success. When the times that the pre-service teachers
preferred to study lessons were examined, a significant difference was
determined, with those preferring to work in the evening showing a lesser
tendency for academic procrastination.&nbsp;&nbsp;
