Authors: Sekirin Alexey B. , Prikuls Vladislav F. , Maybrodskaya Alexandra E.
Published: October 2020

Objective. To increase the efficiency of the complex of therapeutic and rehabilitation measures in preparation for hip joint endoprosthetics.
Materials and methods. 66 patients in whom it was planned to perform hip joint endoprosthetics took part in the research. They were divided into two groups. The main group (n = 32) included patients who underwent 5 binaural beats as a relaxation program. In the comparison group (n = 34) the patients received a standard set of measures to prepare for this operation. All patients were screened for depression and anxiety using the standardized hospital scale for anxiety and depression (HADS) before the study. We also recorded the initial levels of reactive and personality anxiety using the Spielberger Hanin test. We repeated the test in both groups after 7 days to evaluate the dynamics of the test.
Results. The conducted research showed that in the main group on the background of binaural beating procedures, reactive (from 57.2 3.8 to 42.4 5.2 points, p = 0.014) and personal anxiety (from 58.9 4.1 to 44.7 3.8 points, p = 0.003) were significantly reduced. In addition, the application of binaural beats method resulted in a significant decrease of HADS alarm subscale indexes (p 0.001) in patients of the base group from 12.8 2.8 to 8.5 0.7 points. While patients in the comparison group had significantly less expressed decrease of this parameter from 11.7 3.1 to 10.9 1.6 points (p 0.01). On the HADS depression subscale there was also a marked decrease in the main group to 7.1 0.8 points, this value was statistically significantly lower (p = 0.011) than in the comparison group 10.2 1.2 points.
Conclusion. The conducted research has shown that the use of the binaural beats method in the complex of measures to prepare patients for hip joint endoprosthetics helps to improve their psycho-emotional status. This is manifested by a decrease in personal and reactive anxiety in the Spielberger Hanin test, as well as the severity of depression and anxiety on the HADS scale. The advantages of the method are non-invasive and easy to use, and the disadvantages include the duration of the procedure and poorly studied mechanism of action.

Authors: Ma Xiao , Zhao Lian-Feng , Xie Xiao-Bi , He Xi , Yao Zhen-Xing
Published: October 2020

The applicability of the empirical magnitude–yield relations developed for northeast China and Korean Peninsula explosions was investigated for data from northwest China. We collected regional broadband digital seismic data from 13 chemical explosions (CEx) detonated between 6 September and 10 October 2018, on the eastern margin of the Junggar basin, northwest China, five nuclear tests at the Semipalatinsk nuclear test site, and eight natural earthquakes. Both Lg and Rayleigh-wave magnitudes (mb(Lg) and Ms, respectively) were estimated for these events. Similar to the North Korean test site, the mb(Lg)–Ms discriminant did not properly distinguish explosions from natural earthquakes at the Semipalatinsk test site. However, network-averaged P/S spectral ratios (Pg/Lg, Pn/Lg, and Pn/Sn) did successfully discriminate explosions from earthquakes at both the North Korean and the Semipalatinsk test sites at frequencies above 2.0 Hz. Based on 13 known-yield CEx, we selected an empirical magnitude–yield relation to constrain the explosive yields of five historical nuclear tests at the Semipalatinsk test site. The resulting yields are lower than those previously obtained from teleseismic observations.
At the Center of the Controversy: Confronting Ethnic Fraud in the Arts
Authors: Holland Ashley
Published: October 2020

The large-scale retrospective exhibition Jimmie Durham: At the Center of the World (re)introduced self-identified “Cherokee” artist Jimmie Durham to a mainstream audience. Despite efforts in the 1990s to unmask the impostor, who has no known or recognized tribal affiliation, once again Durham was occupying space as a Native artist in the art world. This article addresses larger issues that face the field of Native art and Native representation in museums as a whole, offering personal reflections and a brief review of the exhibition as well as a biographical overview of the artist.
The Artist Knows Best: The De-Professionalism of a Profession
Authors: Mithlo Nancy Marie
Published: October 2020

The traveling art exhibit Jimmie Durham: At the Center of the World (2017–2018) demonstrated three powerful art world tendencies: the use of fraud as an artistic register, the assertion of the artist as authority, and the decontextualization of the arts as an object-centered analysis. These three approaches are congruent with capitalism and the private market, while simultaneously negating Indigenous values of community-based knowledges that operate largely outside the commercial sphere. An analysis of these competing art world values reveals the complicity of public museums with private gain and not education, their stated mission. Ethnic fraud demonstrates how art institutions and their staff employ “selective worth” as a means to cloak the arbitrary exertion of power and simultaneous rejection of Indigenous studies as academic discipline built on the value of tribal sovereignty. Serving as a backdrop for these conversations are a discussion of the history of Native approaches to museology from the early tribal museum era forward and an examination of current “reformist” and “radical” approaches to theorizing Native arts.

Authors: Cambra-Badii Irene
Published: October 2020

Propósito/Contexto. Este artículo tiene como propósito indagar sobre la enseñanza universitaria de la ética, en ciencias de la salud, a través de una serie televisiva. Las experiencias formativas en esta área suelen enfocarse en la práctica profesional futura a través de casos clínicos breves, dejando relegado el ámbito educativo.

Metodología/Enfoque. La metodología utilizada es mixta. Se toma como antecedente la herramienta REST para la evaluación de la sensibilidad ética a partir de la detección de elementos dilemáticos en un audiovisual y se realiza una experiencia de innovación docente con un fragmento de la serie Merlí donde se relata un caso de deshonestidad académica. Los estudiantes debían delimitar las situaciones dilemáticas del fragmento y articularlas con el código de ética universitario. El estudio incluye elementos cuantitativos de la detección de situaciones y principios éticos, y elementos cualitativos de análisis de contenido.

Resultados/Hallazgos. Los resultados son, por un lado, la identificación de todas las situaciones del fragmento, focalizándose en mayor medida en aquellas que tienen como protagonistas a los docentes y, además, en las que implican una transgresión explícita de las normas. Los estudiantes pueden identificar situaciones dilemáticas pero les resulta más complejo vincularlas a los principios éticos.

Discusión/Conclusiones/Contribuciones. La contribución principal del artículo es la advertencia sobre la relevancia de la aplicación y la reflexión sobre la ética en el ámbito universitario, a la vez que se destaca la utilidad del cine y las series televisivas en experiencias de innovación pedagógica en ética y bioética.

Published: October 2020

Outdoor fitness equipment in parks and green spaces improves access and opportunities for physical activity. Evaluating the use of this equipment is important, as data collected from such assessments can be used to guide future planning and strengthen promotion of physical activity. However, determining equipment usage can be challenging, especially when relying on surveys and in-person observational assessments, which are often time consuming and labor intensive. This project used a commercial activity tracker, the Fitbit Zip, to assess the use of the equipment at eight rural community parks and one green space where fitness equipment was placed. The tracker was placed on elliptical units and was triggered by user movement. This information provided insight into the frequency of equipment use. The objective of this article is to describe the method used and the type of data collected.
A Historical Geospatial Analysis of Severe Weather Events in Oklahoma State Parks: A Park Management Perspective
Authors: Wu I-Chun , Mathews Adam , Liu Hung-Ling , Rose Nicholas
Published: October 2020

The State of Oklahoma, located in the heart of Tornado Alley, frequently experiences severe weather events such as tornadoes, hail, and damaging wind. Weather events such as these inflict injury and, in some cases, death on park visitors as well as damage park infrastructure, amenities, and other natural resources. Park and recreation professionals, especially those in severe weather-prone areas, must prepare for and respond to such events with the appropriate emergency operations and hazard mitigation procedures (National Park Service, 2006; Whitworth & May, 2006). Following the tourism disaster and crisis management frameworks (Faulkner, 2001; Ritchie, 2008), this study focuses on risk analysis and hazard mitigation strategies and implementations applicable to parks and recreation areas. Additionally, this study seeks to remedy the lack of longitudinal historical research by employing geographic information system (GIS)-based approaches to investigate the spatial interaction between severe weather events and state parks. Using geospatial data of tornado, hail, wind, and lightning events from 1950 to 2015, provided by NOAA’s National Weather Service Storm Prediction Center, we quantitatively evaluate the potential risk of severe weather on Oklahoma State Parks. GIS-based kernel density estimation was utilized to create interpolated raster surfaces representing accumulated risk (1950-2015) for each type of severe weather event (similar to Dixon et al., 2011). Results show that tornadoes had the most widespread impact on parks in central to north-central regions of Oklahoma. Conversely, the risk posed by hail is more prevalent in parks located in western Oklahoma while parks in northeastern Oklahoma are most affected by severe winds. Parks located in the southeastern corner of Oklahoma have higher chance of lightning strikes. By combining all types of severe weather as a composite dataset, a ‘severe weather risk’ score was assigned to each state park. Natural hazard mitigation strategies and recommendations include allocate operation and maintenance appropriation to severe weather-prone state parks, strengthen emergency response procedure and training programs, and raise natural hazard awareness through communication and education programs. Although this study emphasizes a state-level administration, these methods are transferable to other scales (i.e., national, local) depending on data availability. Conceptual contributions to the tourism disaster and crisis management framework are also discussed.
Is a Decline in Parks Provision Inevitable in Fast-Growth Cities? Evidence from Texas
Authors: Crompton John L. , Ellis Gary D.
Published: October 2020

The study explored whether fast-growth cities in Texas were able to retain their existing level of park supply over a 12-year period between 2008 and 2020. Directors of 50 Texas cities were surveyed in each of those years. Analyses showed the ratio of parks per thousand people was significantly lower in 2020 than in 2008. Correlation results suggested the higher the rate of growth, the more challenging it is for cities to retain their existing levels of service. The negative impact of growth was significantly mitigated in cities that had a parkland dedication ordinance. The results suggest there is a significant probability there will be a decline in parks provision in fast-growth cities, but the finding that there was no decline in 30% of cities in this sample offers a source of encouragement.

Published: October 2020

Understanding visitor travel patterns within parks and protected areas has continually been recognized as beneficial for managers. This information can identify high-use areas and locations of potential conflicts. However, visitor travel patterns can be difficult to understand in parks and protected areas that lack organizational infrastructure, such as trails, roads, or signs (e.g., open deserts and marine environments). In this article, we demonstrate a digital grid analysis of travel patterns at the Bonneville Salt Flats Special Recreation Management Area, Utah, a vast desert expanse where trails, roads, or wayfinding signs do not exist and there is no vehicular speed limit. Data were collected using GPS data loggers and analyzed using ArcGIS. We first conducted spatial descriptive analysis to understand mean center point, median center point, directional distribution, and central line feature. Mean center point and median center point were reported in decimal degrees, which can be inputted into any smartphone or GPS unit for navigation. Using ArcMap, we designed a digital grid that overlaid the study site. The grid provided insight into spatial variations of visitor use and vehicle speeds. Using hot spot analysis, we determined areas where high use and high vehicle speeds were coinciding, which informed a spatial grouping analysis to identify areas for future monitoring. Monitoring areas are reported using navigation directions for easy location. We identified two areas where high use and high vehicle speeds coincide. Both of these areas are near the end of the access road, which suggests some visitors drive fast immediately upon entering the Bonneville Salt Flats. This finding led us to recommend managers put a speed limit zone near the access road for visitor safety. The findings of this study demonstrate the utility of grid analysis for advancing understanding of spatial variations, visitor travel patterns, and identifying priority areas to monitor in a dispersed recreation environment.
Estudio fonológico de los radicales del maya yucateco colonial
Authors: Álvarez L. María Cristina
Published: October 2020

Se realiza una investigación de los radicales del Maya Yucateco Colonial, de acuerdo con la fonémica y la semántica del idioma. El propósito de este trabajo es reunir en un racimo a aquellos radicales que tengan un significado relacionado y deducir o encontrar el posible significado de una raíz base de la que posiblemente deriven las demás. Para poder realizar este trabajo, es importante tener un conocimiento, lo mas profundo posible, del funcionamiento fonémico y semántico de los radicales; ya que muchos cambios consonánticos y vocálicos de los radicales no pueden ser explicados solamente con la semántica, en cambio, gran parte de estos pueden ser explicados por el funcionamiento de los fonemas que estructuran a los radicales. La mayoría de los especialistas de la escritura maya esta de acuerdo en que gran parte de los glifos centrales o principales de los cartuchos corresponden a raíces monosilábicas de la lengua. Por lo tanto, un estudio cuidadoso de los radicales del idioma será de gran utilidad para hacer un estudio comparativo de los radicales del maya yucateco colonial con el glifo central o principal de los cartuchos que se presentan en la escritura maya de los códices. De este estudio se exceptuaran los cartuchos que representan a los dioses, por que tal vez no correspondan a un solo radical sino a expresiones complejas del idioma. Se espera que el conocimiento detallado de los radicales y de sus relaciones formales y semánticas permita identificarlos con algunos glifos centrales de los cartuchos y quizá pueda encontrarse la razón por la que estos glifos van asociadas frecuentemente a otros signos.
Estructura del idioma en que se escribieron los códices mayas
Authors: Álvarez L. María Cristina
Published: October 2020

Es importante para el estudio del descifre de la escritura maya tratar de determinar, sólo como punto de partida, la estructura del idioma empleado en la escritura glífica. El estudio estructural debe comprender los tres niveles lingüísticos fonológico, morfológico y sintáctico. Todo idioma puede expresarse en forma oral y en forma escrita: en un memento dado, en cualquier fecha que se proponga, por la estructura del idioma deben corresponder la forma oral y la forma escrita. Es necesario tener presente que el idioma empleado por los sacerdotes mayas, que se conservaba en forma escrita en los códices y se expresaba en forma oral, empleaba términos y simbolismos especiales; para poderlos entender, y sobre todo escribir, se necesitaba una preparación especializada que no tenia la gente del pueblo. A esta "Forma" del lenguaje empleada por los sacerdotes se le llama "Código" para diferenciarla de la forma oral y la forma escrita que venimos utilizando en este estudio. Este "Código" no debe haber cambiado mucho debido a la función socio-religiosa tan importante que tenia, ya que se empleaba para establecer comunicación con los dioses, donadores de beneficios o maleficios, y para las necesidades del pueblo en general.

Yucatán: El uso de dos lenguas en contacto
Authors: Pfeiler Barbara
Published: October 2020

En los censos oficiales se considera que Yucatán es el estado mexicano con el mayor grado de bilingüismo. No existe un solo municipio en Yucatán en el cual no se use el maya-yucateco. Pero al tomar en cuenta la política lingüística histórica y actual, la situación lingüística en Yucatán esta caracterizada por el fenómeno "diglosia con bilingüismo (Fishman, J97la: 75). La diglosia se manifiesta de tal manera que a nivel nacional existe una lengua dominante y oficial junto a otra lengua subordinada y no estandarizada. El desequilibrio de las dos lenguas en contacto no es resultado del racismo, sino más bien de los diferentes factores socioeconómicos y demográficos. Según la definición de Fishman (1967) predomina el bilingüismo individual en Yucatán. La diglosia en cambio, se da en el nivel sociocultural. La cuestión de hasta que grado se manifiesta esta situación lingüística es el ambiente rural del estado de Yucatán depende de los factores demográficos y económicos de cada comunidad. La zona agrícola maicera presenta el porcentaje mas alto de población monolingüe, seguida de las zonas: henequenera, ganadera, frutícola y por último la pesquera.
EDUCATION IN MODERN SOCIOCULTURAL CONDITIONS: NEW CHALLENGES, OPPORTUNITIES, RESPONSIBILITY

Published: October 2020

The problem of upbringing in modern socio-cultural conditions is very significant and relevant. Modern reality has a significant positive educational potential, creates a new space for personality development, self-determination, self-organization and self-realization. The transformations in modern Russia, the preparation of a new generation of russians who are able to successfully carry out these transformations in the interests of the individual, society and the state, overcoming numerous manifestations of lack of spirituality in children and youth require an increase in the role of education in educational organizations as a social institution. In this regard, this article deals with new approaches to the organization of educational activities in the education system. The article notes that in modern socio-cultural conditions, education should be focused on achieving two interrelated goals: the success of socialization of the younger generations in modern conditions and self-development of a person as a subject of activity, as a person and as an individual. Education is viewed as a pedagogically organized and purposeful process of personality development, the process of mastering and accepting values, moral attitudes and moral norms of society. The main content of education is to ensure the process of socialization and self-development of a young person on the basis of technologies and means of pedagogical assistance, support and accompaniment. The article also takes into account the fact that in connection with the legislative initiative of the President of the Russian Federation V.V. Putin of May 21, 2020 on the draft federal law "On amendments to the federal law" On education in the Russian Federation " the appeal, first of all, to the problem of upbringing in the education system acquires special relevance. Thus, there is a conscious need of the state to restore the upbringing function of education and in its new understanding. The material is revealed on the basis of a systematic approach to education, where the child is the main subject.
INNOVATIVE DEVELOPMENT OF RUSSIAN REGIONS ACCORDING TO THE «TRIPLE HELIX» MODEL
Authors:   Yaroslavl state pedagogical university named after K. D. Ushinsky, Batrakova Lyudmila G.
Published: October 2020

The topic of the article is extremely relevant for modern Russia. The formation of an innovative economy begins with the creation of an innovative climate and the definition of a model for further development. To assess the innovation system of regions, the AIRR rating is used, based on the calculation of 29 indicators. The rating data shows managers the strengths and weaknesses of development and allows them to adjust the innovation policy of the regions. The article presents the data of the "rating of innovative development of the Russian Federation subjects" based on the results of 2017. It is shown that if you divide the regions into 3 groups (advanced, medium and lagging), the number of subjects of the Russian Federation in them is approximately the same. The article describes possible ways to coordinate relations in different types of economies. More attention is paid to partnerships in the post-industrial online economy. This economy is characterized by the interaction of three subjects in the network mode and thus forms a "triple helix". According to the "triple helix" concept, the formation and implementation of innovations should be based on universities that interact with business and government. In Europe, the "triple helix" model of innovative development is the main one in regional development. The article focuses on the problems of the formation of the "triple helix" in the regions of Russia. At the same time, successful examples of effective interaction of science with business and government are given. A continuation of the "triple helix" concept is the "quad helix" theory, in which the Quad element is the users of innovation, i.e. citizens who are the driving force of the innovation process. The forms of implementation of the "quad helix" model are aimed at the development of the region's human capital.

Light Trapping in Single Elliptical Silicon Nanowires
Authors: Liu Wenfu , Wang Yinling , Guo Xiaolei , Song Jun , Wang Xiao , Yi Yasha
Published: October 2020

Light trapping in single nanowires (NWs) are of vital importance for photovoltaic applications. However, circular NWs (CNWs) can limit its light-trapping ability due to high geometrical symmetry. In this work, we present a detailed study of light trapping in single NWs with an elliptical cross-section (ENWs). We demonstrate that the ENWs exhibit significantly enhanced light trapping compared with the CNWs, which can be ascribed to the symmetry-broken structure that can orthogonalize the direction of light illumination and the leaky mode resonances (LMRs). That is, the elliptical cross-section can simultaneously increase the light path length by increasing the vertical axis and reshape the LMR modes by decreasing the horizontal axis. We found that the light absorption can be engineered via tuning the horizontal and vertical axes, the photocurrent is significantly enhanced by 374.0% (150.3%, 74.1%) or 146.1% (61.0%, 35.3%) in comparison with that of the CNWs with the same diameter as the horizontal axis of 100 (200, 400) nm or the vertical axis of 1000 nm, respectively. This work advances our understanding of how to improve light trapping based on the symmetry breaking from the CNWs to ENWs and provides a rational way for designing high-efficiency single or self-assembled NW photovoltaic devices.
Internet, Participation in International Trade and Tax Revenue Instability
Authors: Gnangnon Sena Kimm
Published: October 2020

This paper investigates the effect of the Internet on tax revenue instability, notably through the international trade channel. It has used a sample of 142 countries over the period 1995-2017, and relied primarily on the two-step system Generalized Methods of Moments (GMM) estimators (but also incidentally on the Error Component Two-Stage Least Squares estimator). Tax revenue instability is primarily measured by the instability of non-resource tax revenue, but also by the instability of total tax revenue (for robustness check). The findings indicate that the Internet exerts a negative effect on tax revenue instability. Interestingly, this effect genuinely translates through the international trade channel, regardless of the measure of tax revenue instability considered. Countries enjoy a higher negative effect of the Internet on tax revenue instability as they enjoy a greater participation in international trade. These findings, therefore, add to the potential benefits of the Internet adoption (e.g., strengthening countries' participation in international trade, enhance their tax revenue performance and promote tax reform, including in developing countries) by showing that it could also help to stabilize tax revenue, particularly through the degree of countries' participation in international trade.

(1) Background: A global pandemic due to COVID-19 emerged in November 2019 and hit France in early March 2020. It not only resulted in a loss of lives but also in very strict confinement measures. The objective of this study was to understand what the determinants of the change in participants’ behavior and mental state were during the confinement. (2) Methods: An online survey was launched on April 23rd, 2020, and closed on May 7th, 2020. The final sample included 1454 participants from 24 to 65 years old. Descriptive and multivariate analyses were then performed. (3) Results: 28.7% reported having a more balanced diet, against 17.1% with a less balanced diet. 22.7% of respondents reported an increased alcohol consumption, as opposed to only 12.2% declaring a decrease and 11.2% of respondents increased their tobacco consumption, while 6.3% decreased it. 50.6% of the participants reported being more depressed, stressed, or irritable since the beginning of the lockdown. Confinement had a negative effect on every behavior studied in this survey, except for nutrition. We also found that negative mental state changes were strongly associated with nutrition, sleep, physical activity, and alcohol consumption changes.

Pathogens and adulterants in human feeding consumables can be readily identified according to their electrical properties. Electrical bioimpedance analysis (BIA) has been widely used for body contents characterization, such as blood, urine, lactate and sweat. If the blood glucose concentration alters the electrical properties of the blood medium, then the impedance spectrum obtained by BIA can be used to measure glycemia. In some applications, artificial neural networks allows the correlation of these parameters (impedance and glucose concentration) by means of symbolic and statistical rules. According to our literature review, there is any physical model that allows the interpretation of the relationship between blood’s electrical properties, obtained by BIA, and the concentration of glucose in the blood plasma. This article proposes a simplified physical model for blood electrical conductivity as a function of glucose concentration, based on Bruggeman’s effective medium theory. The equations of this model were obtained considering an insulating phase distribution diffused in a conductive matrix, in which red blood cells are represented by macroscopic insulating nuclei and glucose molecules by microscopic insulating particles. The impedance spectrum for different glucose concentrations (4.0 to 6.8 mmol/L) in a blood sample, published by Kamat Bagul (2014), were compared with the proposed model. The results showed a significant correlation with the experimental data, showing a maximum error of 5.2%. The proposed model might be useful in the design of noninvasive blood glucose monitoring systems.

The subtilase family is the second largest family of serine proteases. Some fungi including Trichoderma species can capture and kill nematodes by secreting hydrolytic enzymes or toxins, among which serine proteases are important enzymes that allow fungi to infect nematodes. Subtilase can degrade nematode and insect body walls. In this study, subtilase family genes were identified from the Trichoderma harzianum genome database, and bioinformatics analysis of the characteristics and evolutionary status of these genes, along with structural and functional analyses of their proteins, was performed. Gene structure analysis revealed that all the 41 subtilase genes contained introns, while some did not have upstream or downstream regions. Chromosome localisation showed that subtilase family members were unevenly distributed in 22 Trichoderma chromosomes, and 3 clusters were present, indicating that they may be hot spots of subtilase genes. Conserved motif analyses showed these proteins contained a commonly conserved motif, and motifs belonging to the same subfamily remained highly similar. The upstream region of the subtilase genes were enriched with different type and numbers of cis-elements, indicating that subtilase genes are likely to play a role in the response to diverse stresses. Transcription of 31 genes was increased after 5 days of infection with nematodes, whereas that of 10 genes decreased. In these subtilase genes, ThSBT4, ThSBT5, ThSBT12, ThSBT27, ThSBT34, ThSBT35, ThSBT38, and ThSBT40 showed significantly upregulated expression with a log2 fold change value of more than 4, and ThSBT35 showed the highest peak. These results laid a theoretical foundation for further research on the function of the subtilase genes and the mechanism of the resistance response.

There is an increasing clinical need to develop novel biomaterials that combine regenerative and biocidal properties. In this work, we present the preparation of silver /silica based glassy bioactive (ABG) compositions via a facile, fast (20h), and low temperature (80 °C) approach and their characterization. The fabrication process included the synthesis of the bioactive glass (BG) particles followed by the surface modification of the bioactive glass with silver nanoparticles. The microstructural features of ABG samples before and after exposure to simulated body fluid (SBF) as well as their ion release behavior during SBF test were evaluated using infrared spectrometry (FTIR), ultraviolet- visible (UV-Vis) spectroscopy, X-ray diffraction (XRD), electron microscopies (TEM and SEM) and optical emission spectroscopy (OES). The antibacterial properties of the experimental compositions were tested against Escherichia coli (E. coli). The results indicated that the prepared ABG materials possess antibacterial activity against E. coli, which is directly correlated with the glass surface modification.

Concretizing the mechanisms of Bergmann rule, we found saw-tooth pattern in body size variation in ground beetle Pterostichus oblongopunctatus. We sampled beetles in 2010 – 2018 at the forest undisturbed plots on the broad territory in Russia. Investigating regions covered territory, extending to 3 degrees latitude and 19 degrees longitude. We measured six traits in every of 3294 caught individual. ANOVA showed that latitude, and sex affected significantly body size of the species studied. Mean values of each trait changed significantly from one studied region to another in females and males as well. Sexual size dimorphism in species was female-biased. We performed models in R to estimate the steepness of body size variation in both sexes. In overwhelming majority of cases that parameter was equal in both sexes. So the hypothesis, that male′s variation is steeper in latitude gradient was not confirmed.
