Published: November 2020

AbstractPeru is experiencing a “gastronomic boom” that is increasing the demand for seafood. We investigated two implicit assumptions of two popular sustainable seafood consumer-based initiatives: (1) seafood is labelled correctly, and (2) the recommended species are healthy for consumers. We used DNA barcoding to determine the taxonomic identity of 449 seafood samples from markets and restaurants and analysed the concentration of total mercury (THg) in a sub-sample (271 samples) of these. We found that a third of seafood is mislabelled and that over a quarter of all samples had mercury levels above the upper limit recommended by the US EPA (300 ng/g ww). Additionally, 30% of samples were threatened and protected species. Mislabelling often occurred for economic reasons and the lack of unique common names. Mislabelled samples also had significantly higher mercury concentrations than correctly labelled samples. The “best choice” species compiled from two sustainable seafood guides had less mislabelling, and when identified correctly through DNA barcoding, had on average lower mercury than the other species. Nevertheless, some high mercury species are included in these lists. Mislabelling makes the efforts of seafood campaigns less effective as does the inclusion of threatened species and species high in mercury.

AbstractThe Griffon vulture was once a widespread species across the region of Southeast Europe, but it is now endangered and in some parts is completely extinct. In the Balkan Peninsula the largest Griffon vulture inland population inhabits the territory of Serbia. We present, for the first time, the genetic data of this valuable population that could be a source for future reintroduction programs planned in South-eastern Europe. To characterize the genetic structure of this population we used microsatellite markers from ten loci. Blood samples were collected from 57 chicks directly in the nests during the ongoing monitoring program. We performed a comparative analysis of the obtained data with the existing data from three native populations from French Pyrenees, Croatia, and Israel. We have assessed the genetic differentiation between different native populations and determined the existence of two genetic clusters that differentiate the populations from the Balkan and Iberian Peninsulas. Furthermore, we analysed whether the recent bottleneck events influenced the genetic structure of the populations studied, and we found that all native populations experienced a recent bottleneck event, and that the population of Israel was the least affected. Nevertheless, the parameters of genetic diversity suggest that all analysed populations have retained a similar level of genetic diversity and that the Griffon vulture population from Serbia exhibits the highest value for private alleles. The results of this study suggest that the Griffon vulture populations of the Balkan Peninsula are genetically differentiated from the populations of the Iberian Peninsula, which is an important information for future reintroduction strategies.

Published: November 2020

AbstractThe plastic zone range is an important parameter in the analysis of damage characteristics and the degree of damage to the rock surrounding a roadway. Based on the establishment of a plastic zone calculation model considering the creep effect, this paper obtains the characteristics of the change in the plastic zone damage range with time by solving the model. Additionally, the validity of the model is verified by field experiments. The research results can provide guidance for gas pressure measurement and gas drainage in coal mines.
Coastal urbanization alters carbon cycling in Tokyo Bay
Authors: Kubo Atsushi , Kanda Jota 
Published: November 2020

AbstractThe carbon budget of Tokyo Bay, a highly urbanized coastal basin, was estimated using a box model that incorporated inorganic and organic carbon data over an annual cycle (2011–2012). The surface water represented net autotrophic system in which the annual net community production (NCP) was 19 × 1010 gC year−1. The annual loading of dissolved inorganic carbon and total organic carbon (TOC) from freshwater inputs was 11.2 × 1010 and 4.9 × 1010 gC year−1, respectively. The annual TOC sedimentation rate was 3.1 × 1010 gC year−1, similar to the annual air–sea CO2 uptake (5.0 × 1010 gC year−1). Although the NCP and TOC loading from freshwater inputs were respectively 3.0 and 2.7 times lower than those in the 1970s, the TOC sedimentation rate was similar. Therefore, a relatively high carbon efflux from Tokyo Bay likely occurred in the 1970s, including CO2 efflux to the atmosphere and/or export of labile organic carbon to the open ocean. The changes in carbon flow between the 1970s and 2011–2012 resulted from improved water quality due to increased sewage treatment facilities and improved sewage treatment efficiency in the catchment, which decreased the amount of labile organic carbon flowing into the bay.

AbstractIn contrast to conventional X-ray therapy, proton beam therapy (PBT) can confine radiation doses to tumours because of the presence of the Bragg peak. However, the precision of the treatment is currently limited by the uncertainty in the beam range. Recently, a unique range verification methodology has been proposed based on simulation studies that exploit spherical ionoacoustic waves with resonant frequency (SPIREs). SPIREs are emitted from spherical gold markers in tumours initially introduced for accurate patient positioning when the proton beam is injected. These waves have a remarkable property: their amplitude is linearly correlated with the residual beam range at the marker position. Here, we present proof-of-principle experiments using short-pulsed proton beams at the clinical dose to demonstrate the feasibility of using SPIREs for beam-range verification with submillimetre accuracy. These results should substantially contribute to reducing the range uncertainty in future PBT applications.

AbstractCerium doped Gd3Ga3Al2O12 (GGAG) single crystals as well as GGAG:Ce single crystals co-doped by divalent (Mg2+, Ca2+) and tetravalent (Zr4+, Ti4+) ions have been studied by means of time-resolved luminescence as well as the excitation luminescence spectroscopy in vacuum ultraviolet (VUV) and soft X-ray (XUV) spectral range. Tunable laser excitation was applied for time-resolved experiments in order to obtain luminescence decay curves under excitations in Ce3+, Gd3+ and excitonic absorption bands. The influence of the co-dopant ions on the Ce3+ luminescence decay kinetics is elucidated. The fastest luminescence decay was observed for the Mg2+ co-doped crystals under any excitation below bandgap energy indicating the perturbation of the 5d states of Ce3+ by Mg2+ ions. Synchrotron radiation was utilized for the luminescence excitation in the energy range from 4.5 to 800 eV. Special attention was paid to the analysis of Ce3+ excitation spectra in VUV and XUV spectral range where multiplication of electronic excitation (MEE) processes occur. Our results demonstrated that GGAG:Ce single crystals co-doped by Mg2+ ions as well as the GGAG:Ce crystal annealed in vacuum reveal the most efficient excitation of Ce3+ emission in VUV-XUV excitation range. The role of intrinsic defects in MEE processes in the co-doped as well as in the annealed GGAG:Ce single crystals is discussed.

Abstract
Survivin is an inhibitor of apoptosis as well as a promoter of cell proliferation. Fibulin-3 is a matrix glycoprotein that displays potential for tumor suppression or propagation. The present study aimed to validate the expression levels of survivin and fibulin-3 in benign and malignant respiratory diseases. This case–control study included 219 patients categorized into five groups. Group A included 63 patients with lung cancer, group B included 63 patients with various benign lung diseases, group D included 45 patients with malignant pleural mesothelioma (MPM), and group E included 48 patients with various benign pleural diseases. Group C included 60 healthy individuals (control group). Serum survivin and fibulin-3 levels were measured by ELISA, whereas their nuclear expressions in the lung and pleura were assessed via Western blot analysis. The results showed significantly higher survivin serum levels and significantly lower fibulin-3 levels in group A compared with in group B and controls (P&lt;0.001). There were significantly higher serum levels of survivin and fibulin-3 in group D compared with in group E and controls (P&lt;0.001), consistent with observed nuclear survivin and fibulin-3 expression levels. Fibulin-3 was determined to have higher value than survivin in discriminating lung cancer from MPM (P&lt;0.05). Survivin and fibulin-3 could be useful diagnostic markers for lung and pleural cancers, and fibulin-3 expression was particularly useful in differentiating lung cancer from MPM.

Published: November 2020

Maintenance of power balance at each time moment in every node and in the electric power system as a whole is a mandatory condition for supplying the electric power of required quality (frequency, voltage levels). Property of the system to be considered as its ability to control power balance is referred to as flexibility. Technologies for operating conditions control or systems services are an efficient means of regulating the flexibility of HV transmission networks in the cycle of on-line and anti-emergency control. Present-day FACTS of the second generation based on power electronics whose control systems ensure high efficiency of control and stabilization are the most perspective means of flexibility regulating and control.
The paper considers potentials of using those devices for regulating the flexibility of 500/200 kV network that is a section of a real EPS. Calculations were performed in the simulation experiment and were based on real telemetry measurements using the State Estimation Software.
The results of the studies have showed that substitution of the first-generation FACTS devices by the controlled second-generation FACTS devices and installation of new present-day FACTS allows notable enhancement of HV electric networks controllability and ensures the required level of networks flexibility.

Authors: Tyurina E. A. , Elsukov P. Yu. , Mednikov A.S. 
Published: November 2020

The growing demand for energy, the depletion of oil and gas reserves, and the threat of global climate change have led to an increase in interest in underground coal gasification technologies (UCG) around the world. The potential for using underground gasification of low-grade coal resources with complex mining and geological conditions is huge. The main challenge is the development of competitive technologies for the production of synthesis gas and production of electricity, heat, and synthetic liquid fuels on its basis.
The paper presents a study of one of the promising areas of the use of UCG gas for the combined production of synthetic liquid fuel (methanol) and electricity. A mathematical model of the installation for combined production of methanol and electricity (ICPME) was developed. Based on this mathematical model, a technical and economic optimization of the parameters was carried out to assess the prospects of the scale of application of this coal processing method.
The purpose of research conducted using the mathematical models of the ICPME is to determine the optimal parameters of the installation and the sensitivity of its economic performance indicators to changes in external conditions.

Published: November 2020

The ‘Power of Siberia’ gas pipeline route passes through the territories of South-West and South Yakutia, where the natural conditions are characterized by severe climatic, complex engineering geological and geocryological conditions. A variety of environmental conditions are mandatory for construction and operation in different areas with long-term soil and hazardous geocryological processes: debris flow formation, aufeis formation, soil heaving, thermokarst, thermosuffosion. Aufeis formation processes will be of particular importance during the construction of the pipeline. As a degree of their occurrence in the Republic of Sakha (Yakutia), it should be mentioned the Aldan upland. Aufeis occur almost in the majority of local stream valleys as a small areas of ice formations, basically confined to floodplain and riverbed.
Aufeis areas had been identified in trace areas by the method of deciphering satellite images within the territory of the hydrogeological zones of the Lena-Amur interfluve. As a result of remote studies, territorial and quantitative distributions in hydrogeological zones have been identified. As a result of the monitoring results the areas of each aufeis are determined and their contours are decoded due to satellite images of recent years (2018-2020).
Krankheitsbezogene Belastungen bei Diabetes
Authors: Ehrmann Dominic 
Published: November 2020

ZUSAMMENFASSUNGDiabetes-Distress stellt ein Maß für verschiedene krankheitsbezogene Belastungen bei Diabetes dar. Es bezeichnet eine mangelnde psychosoziale Anpassung an die Anforderungen des Diabetes und der Behandlung. Diabetes-Distress entsteht, wenn die individuellen Coping-Fähigkeiten nicht ausreichen, um mit diabetesbedingten Stressoren umzugehen. Jedoch kann Diabetes-Distress als eine erwartbare Reaktion verstanden werden und ist nicht per se pathologisch. Ein erhöhtes Ausmaß an Diabetes-Distress geht jedoch mit einem schlechteren Diabetes-Selbstmanagement und einer schlechteren glykämischen Kontrolle einher. Zudem ist ein erhöhter Diabetes-Distress ein Risikofaktor für die Entstehung depressiver Störungen und beeinträchtigt die Lebensqualität. Daher sollte ein regelmäßiges Monitoring mit validierten Fragebögen erfolgen. Interventionsansätze umfassen die regelmäßige Besprechung von emotionalen Aspekten des Diabetes im Rahmen von Einzelgesprächen, die Teilnahme an einer strukturierten Gruppenschulung, sowie spezifische psychosoziale Angebote.

Significance
Plant roots grow toward gravity. The phenomenon is known as “root gravitropism” as early described by Charles Darwin, and it has been well established that the plant hormone auxin plays a central role in this response. The major endogenous auxin, indole-3-acetic acid (IAA), is mainly synthesized from tryptophan via indole-3-pyruvic acid, whereas indole-3-butyric acid (IBA) is a minor precursor of IAA. Previous studies have shown that IAA derived from IBA plays a specific role in regulating lateral root development. However, in the present study we demonstrate through the identification and characterization of IBA transporter NPF7.3/NRT1.5 that IAA synthesized from IBA regulates root gravitropism.
The political nature of fantasy and political fantasies of nature
Authors: Behagel Jelle Hendrik , Mert Ayşem 
Published: November 2020

AbstractWithin post-structuralist discourse theory, there has been an ongoing interest in fantasy and the fantasmatic logic. We propose a new way forward and suggest a focus on fantasies of ‘nature’ and what is deemed ‘natural’. Fantasies are structurally entwined with language, desire, and political ontologies. Discourses of nature hold a privileged position in this entwinement. We use the psychoanalytic concept of fantasy to explore how symbolic engagement with the world is supported by fantasmatic mechanisms. We argue that political fantasies express political subjects and objects via the imaginary mechanisms of splitting and projection. In an era of ecological crises and global pandemics, we find that fantasies that create a split between nature and society are a central part of the transformation of political imaginaries and discourses. Studying fantasies of various “naturecultures” and the politics of nature is thus an important new direction for discourse theory to explore anti-essentialist ontologies.
Discourse, concepts, ideologies
Authors: Freeden Michael 
Published: November 2020

AbstractTwo branches of discourse studies, critical discourse analysis (CDA) and discourse theory (DT), could benefit through extending their critical focus and incorporating findings and methodologies of neighbouring disciplines. While indebted to the attentiveness of CDA to ordinary language, ideology studies have by contrast developed interpretative, non-judgmental analytical frameworks that explore the many-faceted features of ideology, power, and the political. In turn, the macro-focus of DT on binary distinctions, articulatory equivalences, and the construction of hegemony through empty signifiers, overlooks the complex internal conceptual morphology that produces multiple ideological vocabularies. Through a layered filtering of texts, utterances, and linguistic intensities, ideological micro-morphology reveals processes of semantic decontestation in order to defend, alter or criticize political thought-practices. It illuminates the complex interrelationship between word and concept and accepts fantasies as ineluctable and decodable features of communal life. By reaching out beyond their disciplinary confines, the interplay of these parallel approaches could enrich the scholarly understanding of the political.
Memories and semiotic resources in place-making
Authors: Phan Nhan 
Published: November 2020

Abstract
This paper explores how semiotic resources are used to build individuals’ place-making during a walk around the Old
Quarter in Hanoi, Vietnam. Using Lefebvre’s (1991) spatial triad as the
perceived, the lived and the conceived, the paper uses a case study of a local
participant and myself to consider how our differing perspectives affect place-making. I show how the local resident makes meaning using
perceived resources in the here-and-now as backdrops for the lived, presented via his recounting of
memories of activity spaces. I then contrast how these memories differ from the researcher’s place-making, where the
conceived affects how I perceive the significance of visual resources on signs in the here-and-now. The
study shows the value of Lefebvre’s (1991) triad for explaining the conflicting generalisations
researchers have made about the nature of what is seen in the linguistic landscape or about the roles played by linguistic landscape in
defining place.

Authors: Alekseev Gennady , Tereshko Dmitry 
Published: November 2020

Abstract
Inverse problems for a 2D heat conduction model connected with developing technologies of designing thermal concentrators are considered. The shells are assumed consisting of a finite number of sectors every of which is filled with homogeneous isotropic medium. By optimization method these problems are reduced to finite-dimensional extremum problems for the solution of which the particle swarm optimization is used. Rigorous optimization analysis shows that concentrators designed using optimization method have the highest efficiency in the class of devices under consideration and are easy for implementation.

Published: November 2020

Abstract
The result of numerical simulation of a flat channel with a back-facing step in the presence of tabs by the RANS method is presented. The Reynolds number, calculated by the step height and the average flow rate velocity, was Re = 5000. The data obtained made it possible to analyze the dynamics of interaction between the separated flow behind a tab and the region of the main separation behind a step. Tabs have the greatest influence on the area in close proximity to the step.

Published: November 2020

Abstract
Actual fundamental and computational problems of laminar–turbulent transition prediction in aerodynamic flows are discussed. The author’s approach based on the exp(N)-method is briefly described. The results of experimental studies aimed at clarifying the calibration of the exp(N)-method is highlighted. Particularly, one of the main problem is a limited experimental database for verification of different approaches for the transition prediction. To extend such a database, it is necessary to document in detail the flow parameters (velocity, free-stream turbulence level, etc.) and the model parameters (geometry, surface roughness, angle of attack, etc.) as well as to document in a statistically sound way the position of laminar-turbulent transition on the surface of experimental model. To this end we develop an experimental method of parametric measurements in different flow regimes of three-dimensional aerodynamic flows based on the thermal analysis of the surface.
The problem of the natural oscillations of a rectangle in the micropolar theory of elasticity
Authors: Gavrilieva Anna , Grigor’ev Yuri 
Published: November 2020

Abstract
We consider the plane problem of natural harmonic oscillations of a rectangle with mixed boundary conditions within the framework of the linear theory of micropolar elasticity. The exact analytical solution of the problem under consideration was obtained by the new method. A parametric analysis of the obtained exact solution is carried out according to which there is a “size effect”. It consists in an increase in micropolar effects with a decrease in the size of the rectangle compared with the classical case. The proposed method can be developed for the case of other boundary conditions and for the three-dimensional case.
