A vertikálisan integrált vállalatok stratégiai lehetőségei az európai unió liberalizált villamosenergia-piacain
Authors: Deutsch Nikolett
Published: March 2021

Az Európai Unió villamosenergia-piacait érő szabályozási változások és szerkezeti átalakulások új szereplői csoportokat hívtak életre, és megbolygatták a korábbi ágazati erőviszonyokat. Míg a monopol piaci körülmények között a vertikálisan integrált vállalatok stratégiai döntései elsősorban a hosszú távú beruházási döntésekre korlátozódtak, ma már kiemelt figyelmet kell szentelniük a fogyasztók elvárásaira, versenytársaik lépéseire. A szerző tanulmányában azt vizsgálja meg, milyen vállalati és üzleti stratégiákat követnek, követhetnek a domináns piaci részesedéssel bíró vállalatok.
Structural Equation Modeling to Detect Predictors of CD4 Cell Count Change due to Long Term Antiretroviral Therapy Administered to HIV-Positive Adults at Felege Hiwot Teaching and Specialized Hospital, Bahir Dar, Ethiopia
Authors: Tegegne Awoke Seyoum
Published: March 2021

Background The relationship between predictors and the variable of interest was estimated using a structural equation model which is used to predict latent variables. The main advantage of the SEM is the ability to estimate the direct and indirect pathways of the effect of the primary independent variable on the outcome, given sufficient sample sizes. Despite not directly modeling the mediated pathways, GLMMs excluding mediating variables performed well with respect to power, bias and coverage probability in modeling the total effect of the primary independent variables on the outcome. In longitudinal studies, data are collected from subjects at several time points. The main purpose of longitudinal analysis is to detecting the trends or trajectories of the variables of interest. Methods A longitudinal study was conducted on 792 adults living with HIV/AIDS who commenced HAART. Structural equation modeling was used to construct a model to detecting predictors of CD4 cell count change. The procedure was illustrated by applying it to longitudinal health-related quality-of-life data on HIV/AIDS patients, collected from September 2008 to August 2012 monthly for the first six months and quarterly for remaining study period. Results The result of current investigation indicates that CD4 cell count change was highly influenced by certain socio-demographic and clinical variables. Out of all the participants, 141 (82%) have been considered 100% adherent to antiretroviral therapy. Structural equation modeling has confirmed the direct effect that personality (decision-making and tolerance of frustration) has on motives to behave, or act accordingly, which was in turn directly related to medication adherence behaviors. In addition, these behaviors have had a direct and significant effect on viral load, as well as an indirect effect on CD4 cell count. The final model demonstrates the congruence between theory and data (x2/df. = 1.480, goodness of fit index = 0.97, adjusted goodness of fit index = 0.94, comparative fit index = 0.98, root mean square error of approximation = 0.05), accounting for 55.7% of the variance. Conclusions The results of this study support our theoretical model as a conceptual framework for the prediction of medication adherence behaviors in persons living with HIV/AIDS. Implications for designing, implementing, and evaluating intervention programs based on the model are to be discussed.

Report has shown that there is an increase of respiratory disease among bars attendants over time whereby in 2011, 32% of bars attendants reported respiratory diseases. The purpose of this study was to assess the knowledge and attitudes of bar attendants towards second-hand smoke (SHS) at work place in Nyarugenge District, Rwanda. This was a cross-sectional study using mixed methods of both qualitative and quantitative. A total of 384 bar attendants participated in the study. Quantitative data were analyzed using SPSS version 21 while qualitative data were analyzed using thematic analysis. Descriptive analysis using frequency and percentages was computed. he qualitative data was analyzed using thematic analysis. The majority of respondents (66.4%) were within the age group of 28-37 years, 60.2% of respondents were males, 60.9% of respondents were illiterate, and 57.3% of respondents were single at the time of data collection.The majority (78.6%) of the study respondents knew that Smoking is dangerous to human health. The cited consequences of SHS include air pollution that enter the respiratory system and damage the lungs, dizziness and others. All respondents agreed that people who smoke should not be allowed to smoke in public places. Improving bar attendants’ access to health education on SHS and encouraging continuous and constant exposure would significantly increase the knowledge and attitude levels of bar attendants towards SHS.

RESEPSI AL-QUR’AN DI MEDIA SOSIAL: STUDI KASUS FILM ANIMASI NUSSA EPISODE “HIII SEREM!!!”
Authors: A'yun Qurrata
Published: March 2021

This article examines the Qur'anic reception on social media, especially in one episode of the Nussa animated film "Hiii Serem !!!" which aired on Youtube and was watched more than 11.7 million times. This study uses the theory of al-Qur'an reception which was initiated by Ahmad Rafiq. The results show that the animated film Nussa is one of the edutainment shows for children who also perceive the Qur'an and the hadith in it. The reception in the episode "Hiii Serem !!!" is form in the exegesis reception, which was QS. Ali ‘Imran: 185 and in the functional receptions from informative aspect, that is, in order not to be afraid of people who die due to certain death for every human being. The transmission process at the reception above is also known through two agents, namely through the character Umma and the text of the conclusion of the wisdom of the story at the end of the screen. While the transformation that occurs in it can be classified into two forms, namely summation and expansion. Summarizing because not all messages of verse 185 are delivered, expansion because there are several other points in the explanation of the verse by Umma that are not found in the previous commentaries. Factors that influence these forms of reception, transmission and transformation are the form of media to deliver messages that are also different from those that already exist, namely in the form of animation/visuals that are disseminated through social media.

The position of the genitive in Old English prose: Intertextual differences and the role of Latin
Authors: Cichosz Anna , Grabski Maciej
Published: March 2021

The present article is a systematic, large-scale corpus study of the varying position of the Old English adnominal genitive. Particular focus is put on intertextual variation and the potential influence of Latin, which is analysed alongside such intra-linguistic factors as syntactic weight and the animacy of the referent. The model of logistic regression adopted helps address a key issue in studies on genitive placement, namely, if and how multiple variables exert combined impact on the choice of the variant. The paper highlights the importance of a bottom-to-top approach in studies of older English syntax, as global tendencies turn out to be the corollary of significantly different contributions on the level of individual texts, whose translation status (original composition or translation) is also of importance to the variation studied.
Braucht Deutschland eine Wegzugsbesteuerung für Akademiker?
Authors: Hubmann Maximilian
Published: March 2021

Einkommen aus Human- und Sachkapital werden steuerrechtlich sowohl in nationalen als auch in grenzüberschreitenden Sachverhalten unterschiedlich behandelt. Dem Grundsatz des Äquivalenzprinzips folgend soll mit der Besteuerung von Einkommen und Vermögen ein pauschalierter Ausgleich für die Nutzung staatlicher Leistungen erhoben werden. Bei Unternehmen wird so die Besteuerung der stillen Reserven begründet, wenn diese Wirtschaftsgüter ins Ausland übertragen oder ihren Sitz verlegen. Beim Wegzug natürlicher Personen werden ebenfalls die stillen Reserven des Sachkapitals besteuert, nicht jedoch das Humankapital. Dies stellt insbesondere bei Hochschulabsolventen eine steuerliche Ungleichbehandlung dar, da der Zugang zu Hochschulbildung weitestgehend steuerfinanziert ist. Sofern nach dem Ende des Studiums ein Wegzug ins Ausland erfolgt, wird diese staatlich geförderte Humankapitalakkumulation im Staat des Kapitalerwerbs nicht besteuert.

Maximilian Hubmann greift die unterschiedliche Besteuerung von Human- und Sachkapital in Deutschland auf und untersucht, inwiefern (Un-)Gleichbehandlung vorliegt. Insbesondere wird aufgezeigt, dass Asymmetrien in der Wegzugsbesteuerung vor dem Hintergrund des Äquivalenzprinzips und des Leistungsfähigkeitsprinzips nicht gerechtfertigt sind.

Businesses use sponsorships to engage a variety of stakeholder groups. How the spending of these sponsorship dollars is connected to the company strategy and measured has been widely researched from the perspective of the sponsoring business. Communications managers in not-for-profits and charities also need to understand how the organizations who sponsor them can benefit from the use of PR and communications to deliver a more valuable funding relationship and build lasing partnerships. This paper explores how the Executive Directors for not-for-profits and charities structure their donor communications in the Canadian agricultural sector. From the review of the literature and the interviews, three Best Management Practices are made.
Social media: Are the lines between professional and personal use blurring?
Authors: Cassano Rizzuti Josie
Published: March 2021

A key aspect of understanding communications in a global environment is understanding social media usage. With the recent dramatic increase in social media usage in the past decade, the incorporation of social media and online platforms into communication strategies of organizations has been intensively discussed and researched. This study investigates social media usage at a global manufacturer to understand how it is being used for business purposes. Are personal and professional lines blurring with social media use? With the increased use of social media in the workplace, our professional and personal lives are increasingly becoming intertwined. The literature suggests that social media interaction and managing the boundaries is more difficult online than offline. Social media is where the lines are blurred between our professional and private lives. It is where we share our food, music, movies, pictures, purchases, politics, and our every-day patterns, alongside our daily professions, on display for the entire world to see.

Selection of Judges for Administrative Courts
Authors: Deviatnikovaitė Ieva
Published: March 2021

Administrative law, unlike civil or criminal law, is not a codified branch of law and it is characterized by a large number of sources of different legal force. Thus, a judge hearing administrative disputes must have particularly deep knowledge of administrative law. The article analyzes the experience of France, Germany, the Czech Republic, Slovakia, Poland, and Lithuania in selecting candidates for judges to work with administrative cases.
Building a Community Partnership in a Pandemic: NJ Pediatric Residency Advocacy Collaborative
Authors: Traba Christin , Pai Shilpa , Bode Sara , Hoffman Benjamin
Published: March 2021

The New Jersey Pediatric Residency Advocacy Collaborative (NJPRAC) is a statewide collaborative with faculty leads from each of the 10 New Jersey pediatric residency programs. The 2 major goals of the collaborative were to build community partnerships between pediatric residency programs and local organizations and develop a core advocacy curriculum. In this article, we focus on how the NJPRAC built community partnerships with Family Success Centers (FSCs) across the state over the course of a 2-year period. FSCs are located within every county in the state and fall under the New Jersey Department of Children and Families, providing resources and supports for families in crisis, with a focus on child abuse prevention services. Amid this growing partnership, the coronavirus disease 2019 (COVID-19) pandemic forced the NJPRAC to swiftly pivot its partnership and develop innovative programs to support families during the COVID-19 pandemic. As FSC leadership communicated families’ concerns to the collaborative, we initiated the Virtual House Call webinar, which incorporated pediatricians, community leaders, and allied health professionals to answer COVID-19 questions. These webinars quickly expanded into weekly interprofessional series, with experts in mental health, law, nutrition, and dentistry partnering with pediatricians from various subspecialties. Key to the webinars’ success was responding in real time to audience questions, collaborating with the FSC leadership on content, and garnering the support from the local New Jersey Chapter, American Academy of Pediatrics and the national American Academy of Pediatrics. A key challenge remains to meaningfully incorporate pediatric trainees into community partnerships. The NJPRAC plans to continue the Virtual House Call series with continuous input from the FSCs and participating families.
Differences in Metacognitive Skills among Undergraduate Students in Education, Psychology, and Medicine
Authors: Gutierrez de Blume Antonio P. , Montoya Londoño Diana Marcela
Published: March 2021

Metacognitive skills such as when and why to apply strategies successfully given task demands (conditional knowledge) and those that assist in regulation like comprehension monitoring are essential for effective learning. However, the debate regarding whether metacognitive skills are domain general or domain specific continues to rage among scholars.Presumably, if metacognitive skills are domain specific, there should be significant differences between domains whereas if they are domain general, there should be no differences across domains. Thus, in the present study we examined the generality/specificity of metacognitive skills (knowledge of cognition: declarative, procedural, and conditional; regulation of cognition: planning, information management, debugging, comprehension monitoring, and evaluation) in a sample of Colombian university students (N = 507) studying education (N = 156), psychology (N = 166), and medicine (N = 185) employing the Spanish version of the Metacognitive Awareness Inventory. Results revealed that there were significant differences in all but two metacognitive skills (procedural knowledge and debugging) across domains, largely supporting the domain specific hypothesis, but also partially supporting the domain general view. Implications and recommendation of the findings for theory, research, and practice are discussed.

Criteria for the suspicion and diagnosis of acute food protein-induced enterocolitis syndrome
Authors: Miceli Sopo Stefano
Published: March 2021

Over the past decades, several panels of criteria have been proposed for the diagnosis of acute food protein-induced enterocolitis syndrome (FPIES). However, none of them have been validated by a prospective study. Such a study is not easy to carry out, because even the children who most of us would certainly believe to be suffering from acute FPIES, possibly serious, should be subject to oral food challenge (OFC). Moreover, the presence of different phenotypes of the acute FPIES may mean that some of them do not fit into any of the above criteria panels. Particularly, Vazquez-Ortiz et al. reported that milder cases (1/4 in their Southern European cohort) might not be captured by the 2017 Consensus diagnostic criteria, which are the most shared till date. Those authors, as well as all interested researchers, claim for accurate diagnostic bio-markers which, however, are not available at the moment.
The CXCR5 T follicular helper cell compartment in children with antibody deficiencies – in search of a prognostic marker of childhood hypogammaglobulinemia
Authors: Szczawinska-Poplonyk Aleksandra , Tapolska-Jozwiak Katarzyna , Samara Husam , Boruczkowski Maciej , Wieckowska Barbara
Published: March 2021

Background: Novel immunodiagnostic markers are required in order to discriminate between mild hypogammaglobulinemia and severe humoral primary immune deficiencies in children. The efficacy of an antibody response to infections and vaccines is underpinned by T follicular helper (Tfh) cells, activating an immunoglobulin class switch recombination, somatic hyper-mutations, and affinity maturation.
Objective: To determine the formation of the Tfh cells in antibody deficient children and to define their importance as prognostic markers helpful in defining the severity of hypogammaglobulinemia.
Methods: We retrospectively reviewed medical records of 200 children aged from 2 months to 10 years, in whom hypogammaglobulinemia was assessed, from January to December 2019. In all the children studied, a flow cytometric analysis of the Tfh cell compartment was performed.
Results: In young infants aged from 2 to 9 months, the mean relative frequency of the Tfh population was lower than in the control population. Concomitantly, the relative values of Tfh cells, corresponding with the 95th percentile, were below the reference values in all age groups.
Conclusions: A deficiency of Tfh cells in young infants mirrors the immaturity of the humoral immune response, whereas in older children Tfh cells are proposed as a prognostic marker facilitating to distinguish between mild hypogammaglobulinemia and the developing common variable immunodeficiency.

The class of the transform of Laplace from the transform of Fourier is considered from some functions without a regularity in null. The functions are regular in the opened area of 0. It is proved, that the sine transform of Fourier from the cosine transform of Fourier is equal to the cosine transform from the sine transform of Fourier on the module.
On the Numerical Solution of Initial-Boundary Value Problems for the Convection-Diffusion Equation with a Fractional Caputo Derivative and a Nonlocal Linear Source
Authors: Apekov Aslan , Beshtokov Murat , Beshtokova Zaryana , Shomakhov Zamir
Published: March 2021

In a rectangular domain the first and third initial-boundary value problems are studied for the one-dimensional with respect to the spatial variable diffusion convection equation with a fractional Caputo derivative and a nonlocal linear source of integral form. Using the method of energy inequalities, under the assumption of the existence of a regular solution, a priori estimates are obtained in differential form, which implies the uniqueness and continuous dependence of the solution on the input data of the problem.

On a uniform grid, two difference schemes are constructed that approximate the first and third initial-boundary value problems, respectively. For the solution of the difference problems, a priori estimates are obtained in the difference interpretation. The obtained estimates in difference form imply uniqueness and stability, as well as convergence at a rate equal to the order of the approximation error.

An algorithm for the approximate solution of the third boundary value problem is constructed, numerical calculations of test examples are carried out, illustrating the theoretical results obtained in this work.
Optimal Gyrodine Rotor Shape in the Class of Conical Bodies
Authors: Biryuk Andrey , Drobotenko Mikhail , Ryadchikov Igor , Svidlov Alexander
Published: March 2021

The problem is to find the optimal shape of the gyrodine rotor and its angular rotation speed that maximizes the angular momentum relative to the axis of rotation at a fixed radius, mass and material of the rotor, taking into account the final strength of the material. The gyrodine rotor is a body of revolution, the thickness of which depends only on the distance r to the axis of rotation, r ∈ [0,R], where R is the radius of the rotor. The rotor surface is defined by rotating the curves z = ±z(r) around the axis. When the rotor is spinning, it undergoes deformation due to centrifugal forces. Normal stress fields appear: radial and annular. Assuming the rotor to be thin, deformations can be described by the functions of the radial displacement of the rotor points u(r). Stress fields can be expressed in terms of this function. The functions u(r) and z(r) are related by the equation of the elastically deformed state. This equation is supplied with the boundary conditions for the absence of radial stresses at r = R and the condition for the absence of displacement on the axis of rotation u(0) = 0. Using the numerical solution of the equation, the problem is solved for the class of conical rotors z(r) = a + br with two parameters a and b. The numerical method is used due to the fact that even in this relatively simple case the problem cannot be solved analytically. Several integrable cases are used to analyze the calculation error in the numerical solution of the problem. The dependence of the problem on the Poisson ratio μ ∈ (−1.1) is investigated, with the remaining parameters fixed. The gain in the angular momentum relative to a rotor of constant thickness is compared.

The optimal steel conical rotor (μ = 0.3) is 2.068 times thicker at the center than at the edge. Its advantage in the angular momentum over the rotor of constant thickness is 3.2 %.
Spermidine supplementation in rare translation associated disorders
Authors: Zimmermann Andreas , Carmona-Gutierrez Didac , Madeo Frank
Published: March 2021

The polyamine spermidine is essential for protein translation in eukaryotes, both as a substrate for the hypusination of the translation initiation factor eIF5A as well as general translational fidelity. Dwindling spermidine levels during aging have been implicated in reduced immune cell function through insufficient eIF5A hypusination, which can be restored by external supplementation. Recent findings characterize a group of novel Mendelian disorders linked to EIF5A missense and nonsense variants that cause protein translation defects. In model organisms that recapitulate these mutations, spermidine supplementation was able to alleviate at least some of the concomitant protein translation defects. Here, we discuss the role of spermidine in protein translation and possible therapeutic avenues for translation-associated disorders.
Influence of metabolites of microorganisms from permafrost on the synthesis cytokines by human peripheral blood mononuclear cells in vitro
Authors: Kolyvanova S. S. , Kalenova L. F.
Published: March 2021

Permafrost is a unique ecosystem characterized by consistently negative temperatures. It has been shown that microorganisms can be there in a state of hypometabolism or anabiosis during geological time. It is known that microorganisms occupy a wide habitat due to the presence of multifunctional systems of adaptation and communication. One of the manifestations of these systems is the production of secondary metabolites (MBs), which include signaling molecules that do not have strict species specificity. The biological activity of signaling molecules largely depends on the number of bacterial cells and the temperature of their cultivation.

In this work we used secondary MBs of Bacillus sp. from Permafrost obtained at different temperatures of microorganism cultivation (at -5 °C – “cold” MBs and at 37 °C – “warm” MBs) in doses of 0,05 × 106 (small dose) of microbial cells (m.cl.) in ml of saline or 500 × 106 (high dose) m.cl./ml. The influence of MB of Bacillus sp. for the TNFα, IL-1β, IL-8, IL-2, IFNγ, IL-4 and IL-10 production by human peripheral blood mononuclear cells (MNC) in supernatants of 24-hour cell cultures was estimated by ELISA whith using the “VectorBEST” test system (Russia) on a LUCY-2 (ANTHOS) spectrophotometer (Austria).

It was found that the activity of synthesis by human MNC of the main spectrum of cytokines significantly increased (p < 0.01 for all indicators) under the influence of MB Bacillus sp. regardless of the temperature of their cultivation and the dose of bacteria. The exception was IL-8, the level of which under the influence of a high dose of “warm” MBs didn’t differ from the control. Compared to PHA the cytokines synthesis by MNC depended on the dose and the temperature of obtaining of MBs. Thus, under the influence of “warm” MBs the level of TNFα was significantly lower than its level under the influence of PHA regardless of the dose. Regardless of the temperature of obtaining metabolites the level of IL-8 under the influence of metabolites from a dose of 500 × 106 m.cl. was reduced relative to the PHA group. Comparison of the influence of “warm” and “cold” MBs of Bacillus sp. showed that small doses of “cold” metabolites to a greater extent stimulate the synthesis of pro-inflammatory cytokines (TNFα, IL-1β, IL-8, IFNγ). High doses of “heat” metabolites of Bacillus sp. to a greater extent they activate human MNCs for the synthesis of anti-inflammatory cytokines (IL- 4 and IL-10). Considering that TNFα, IL-1β and IL-10 are cytokines of systemic action and are responsible not only for the activation of the immune system, but also for the mobilization of other regulatory systems of the organism, it can be assumed that the secondary metabolites of microorganisms from Permafrost will be efficient as a substrate for the development of new immunomodulators and adaptogens in the future.
Condition assessment and analysis of a reinforced concrete building in India: a case study
Authors: Anand N , Andrushia Diana , Paul Daniel , Arulraj Prince
Published: March 2021

Structural concrete is a composite material commonly used for the construction of buildings and structures. Reinforced concrete members should be designed for strength, as well as durability. The long service life of the entire structure depends on the durability of concrete. The quality of construction materials, cover to the concrete, exposure conditions and quality of concrete are some of the key factors that affect the durability of concrete. Also, water penetrates easily and finds its way inside concrete through connected pores if the degree of compaction is not proper. Stagnant rainwater in the roof or a high water table may pave the way for the entry of water. The entry of water into structural concrete mainly causes corrosion, thereby reducing the strength of structural elements and initiating the spalling of concrete. A case study based on diagnosis, non-destructive testing and failure analysis of a reinforced concrete building in India is presented. The rehabilitation measures to be undertaken to maintain the service life of the building are also presented.

After those classes they worked out at home their answers referring to issues occurring within the following techniques: 1) the Daily Time Budget, 2) the Brainstorming, 3) the Fishbone Diagram, 4) the Borda-Kendall Method. The results were analysed with the “Statistica” computing package (13.3 version). The significance of intergroup differences (between students of different fields and men and women) was analysed with the χ². Results: It has been found out that there was a significant increase in the time devoted to self-study, watching the Internet and TV, homework. There were no classes in university premises as well as a decrease in social contacts. Among the factors that made studying more difficult, the lack of practical classes was ranked first, Internet problems second, and additional household chores came third. Conclusions: What turned out the most significant among inconveniences of online studies during the pandemic was limitation – or just lack – of practical classes, what is a problem requiring considerations and a systemic solution.

Authors: Kovtun Igor V.
Published: March 2021

The article highlights a series of multicultural images of the developed Bronze Age of the south of Western Siberia, which are connected by a common semantic meaning. The author substantiates lunar semantics of Okunev, Krokhalevka and Samus anthropomorphic characters conveying the idea of significant moon cycles, mainly the new moon, the first quarter and the full moon. The worldviews of the population of these cultures are reconstructed, the probable sources of the lunar cult and the peculiarities of similar views in each community are investigated. Specific iconographic methods of transmitting similar ideological stereotypes by various visual means inherent in the cultural groups of the Upper Ob Region, the Lower Tom Region and the Middle Yenisei in the second half of the 3rd – the beginning of the 2nd millennium BC are revealed

Published: March 2021

The article is dedicated to the publication of a unique find that is a coin-shaped indication from the early medieval burial complex in Tuekta (Central Altai) and an attempt of its comprehensive analysis. Excavations of the archaeological site were carried out in the 1930s during the work of the Sayan-Altai expedition led by S.V. Kiselev, however, since then, the metioned find has not attracted the attention of researchers. The article presents a detailed description of the coin-shaped indication and the analysis of the applied images, it is there also given the characteristic of the archaeological context of the discovery of the object and discuss the possibility of reading fixed signs. As a result, it is presented an attempt to interpret the product in a specific historical and cultural context taking into account the materials received over the past decades. It should be noted the absence of identical archaeological finds in the numismatic collections. At the same time, an analysis of the details of the image on the coin-shaped indication made it possible to outline a wide range of analogies demonstrating the complex processes of cultural contacts in large territories of Eurasia over a long chronological period. The authors came to the conclusion that the analysed product, as well as other like finds from the archaeological sites of the Türks of Inner Asia, to be a kind of “social markers”, demonstrating their owners’ belonging to the elite strata of the nomadic society and, possibly, reflect their specific authority. The proposed interpretation of such things, given their scarcity, as well as the context of discovery not being obvious, seems debatable and, of course, requires the emergence of new data as a result of further archaeological research
Archaeological Science and Education in Siberian Universities at the Turn of the Epochs
Authors: Kitova Lyudmila Yu.
Published: March 2021

This research is devoted to archaeological science and education in Siberia at the end of the 19th century – the first third of the 20th century. The purpose of the article is to analyse the development of Siberian archaeology at the turn of the epochs when high-level professionals first appeared in the region running away from the Bolsheviks from the European part of Russia and evacuated by A.V. Kolchak from Kazan and Perm universities. The reasons for the intensification of archaeological activity in Siberia in 1918–1926 were identified recreating an integral picture of its development. Particular attention is paid to identifying the specifics of the process of training researchers of antiquities at Tomsk and Irkutsk universities. Tomsk University, on the initiative of Professor S.I. Rudenko and lecturer S.A. Teploukhov, provided individual training of paleoethnologists as part of the natural science cycle of disciplines, while Irkutsk University established the first archaeological school in Siberia. The modernisation of higher education in the first years of the Soviet power led to the destruction of emerging historical education at Siberian universities and to the termination of archaeologists’ training as a result
Modelling the Ionic Conductivity of Nanopores with Electrically Conductive Surface

Published: March 2021

The ionic conductivity of nanopores with electrically conductive surface is investigated theoretically. The generalization of two-dimensional (2D) Space–charge model to calculating the ion transport under the applied potential gradient in a nanopore with constant surface potential is proposed for the first time. The results are compared with one-dimensional (1D) Uniform potential model, which is derived from the Space–charge model by assuming the independence of potential, ion concentrations, and pressure on the radial coordinate. We have found that the increase of surface potential magnitude leads to the enhancement of conductivity due to the increase of counter–ion concentration inside the nanopore. It is shown that the 1D and 2D models provide close results when the pore radius is smaller than the Debye length. Otherwise, the 1D model essentially overestimates the ionic conductivity. According to the 2D model, the ionic conductivity decreases with increasing the nanopore radius, while the 1D model predicts the opposite trend, which is not physically correct
