Projeto Sideral e a música de animismo cósmico
Authors: Thompson Reynaldo , Mukhopadhyay Tirtha
Published: March 2020

O projeto Sideral foi desenvolvido pelos artistas Marcela Armas e Gilberto Esparza, como mais um acréscimo à série de esculturas eletrofônicas expostas por Esparza depois que ele recebeu o Golden Nica de 2015. Em seu esquema básico, o Concepción-Adargas, que é o título do trabalho que emana do Projeto Sideral, usa um meteorito de 3,3 toneladas, que atingiu em 1786 o estado de Chihuahua, México e agora é preservado pelo Instituto de Astronomia da Universidade Nacional Autônoma do México (UNAM). O campo magnético na superfície do meteorito é detectado e traduzido em sons que recriam as harmonias distantes de Buchla, de maneira semelhante à composição Licht de Stockhausen ou às canções contemplativas de Pauline Oliveros, por mais importantes que sejam em aspectos do som, é o companheiro de Armas e Esparza, Daniel Llermaly, que os transforma em termos semelhantes aos da música indígena Tarahumara, uma frequência semelhante conhecida pelos povos da região onde o meteorito atingiu.
Colonização e Ensino do Design
Authors: Nani da Fonseca Annelise , Barbosa Ana Mae
Published: March 2020

Este artículo tiene como objetivo analizar la enseñanza del diseño através de estúdios decoloniales. Esto para demonstrar como la colonización de subjetividades interfiere en la enseñanza del diseño y su proceso creativo. Para basar teóricamente los estúdios decoloniales se utilizaron las investigaciones de: Nora Merlin (2019), Victor Kon (2019), Ramón Cabrera (2019), Maria Rita Kell (2019); mientras que, para apoyar la enseñanza del diseño se basa en el trabajo de Ana Mae Barbosa (2008), Lina Bo Bardi (1994) y Adélia do Vale Araújo Cordeiro Almeida (2019). Los análisis revelaron que la colonización todavía interfiere en la comprensión del diseño brasileño y en la elaboración de cursos de diseño, lo que causa um prejuicio con respecto a un proceso creativo autónomo que permite el desarrollo de lenguajes de autor.

Published: March 2020

Оценены адаптивные свойства интрогрессивных линий мягкой яровой пшеницы с чужеродным генетическим материалом на фонах искусственно создаваемых стрессовых факторов. Показана реакция растений как на каждый из изучаемых стрессов, так и на их комплекс. Объектом изучения являлись 12 селекционных линий яровой пшеницы из питомника испытания потомств 2-го года, полученные в результате сложных ступенчатых и беккроссных скрещиваний новых доноров устойчивости к стеблевой ржавчине: линий озимой пшеницы GT 96/90 (Болгария) с генетическим материалом вида Triticum migushovae, 119/4-06rw — видов Aegilops speltoides и Secale cereale; линии яровой пшеницы 113/00i-4 с использованием вида Aegilops triuncialis; ярового образца 145/00i, устойчивого к бурой ржавчине, с генетическим материалом вида Aegilops speltoides. Стрессоустойчивость линий изучали в лабораторных условиях на ранних этапах онтогенеза, используя засоление NaCl и длительное затопление семян в воде (анаэробный стресс). Показатели по солеустойчивости варьировали от 40 до 62 %, по устойчивости к затоплению дифференциация по прорастаемости составила от 8 до 82 %. По суммарному показателю устойчивости самым широким диапазоном адаптивности к токсическому действию обоих стресс-факторов характеризовались линии 37-16i, 33-16i и 32-16i, 3-16i и 9-16i. Полученные данные свидетельствуют о сходной направленности адаптивных процессов при воздействии стрессовых ситуаций и сочетании в 1 генотипе (или почти полная сопряженность результатов) устойчивости одновременно к 2 стресс-факторам — солевому и анаэробному. Повышенный уровень адаптации протестированного материала мягкой пшеницы связываем с наличием чужеродных транслокаций у исходных родительских форм, участвовавших в происхождении линий.

Published: March 2020

The bulgur industry has importance in the food sector in Turkey. The wastewater generated from this industry can be considered bio waste. The microbial fuel cells (MFC) are a relatively new technique aiming to treat the wastewater and producing direct energy. This study aims to explore the degradation efficiency of the organic matters expressed as chemical oxygen demand (COD) founded in bulgur industry wastewater by microbial fuel cell techniques. Furthermore, it aims to study the potential formation of electricity from this type of wastewater. In this study, the MFC – double chamber system was performed. 1.5 L bulgur industry wastewater containing 3% of biomass was used. The COD and the voltage were measured. The COD generated from the bulgur industry wastewater was 28800 mg/L. After using the MFC system, the COD was decreased to reach 2560 mg/L with a removal efficiency of 91%. 1st order kinetic model had the best fit for COD removal with a correlation coefficient (R2) of 0.95. The maximum and average voltages were 0.448 Volt and 0.180 Volt, respectively. The average voltage for every 1 m2 was 45 volt. As a result of the exploratory study, the MFC can be used to treat the bulgur industry wastewater and generating energy. But it should be combined with other treatment methods tomeet the COD standard limits.
The PhyloCode applied to Cintractiellales, a new order of smut fungi with unresolved phylogenetic relationships in the Ustilaginomycotina

Published: March 2020

The PhyloCode is used to classify taxa based on their relation to a most recent common ancestor as recovered from a phylogenetic analysis. We examined the first specimen of Cintractiella (Ustilaginomycotina) collected from Australia and determined its systematic relationship
to other Fungi. Three ribosomal DNA loci were analysed both with and without constraint to a phylogenomic hypothesis of the Ustilaginomycotina. Cintractiella did not share a most recent common ancestor with other orders of smut fungi. We used the PhyloCode to define the
Cintractiellales, a monogeneric order with four species of Cintractiella, including C. scirpodendri sp. nov. on Scirpodendron ghaeri. The Cintractiellales may have shared a most recent common ancestor with the Malasseziomycetes, but are otherwise unresolved
at the rank of class.
Electrical swing adsorption on functionalized hollow fibers
Authors: Wessling Matthias
Published: March 2020

Temperature swing adsorption (TSA) is a favorable adsorption technique when applied for capturing CO2 but limited by long cycle times and low concentrations of the recovered adsorbate. Direct heating of the adsorbent can mitigate these drawbacks. Combined with the beneficial mass transfer of a hollow fiber geometry it offers a powerful sorption process. In this study, we combine the advantages of direct heating and the benefits of the hollow fiber geometry in electrically conducting hybrid hollow fibers. Two different solid sorbents are manufactured and characterized: polyethylenimine-impregnated silicon carbide fibers (SiC-PEI) and fibers consisting of a carbon nanotube matrix with dispersed zeolite particles (CNT-zeolite). Both fibers exhibit Joule heating properties and high adsorption capacities. The CO2 uptake, CO2 isotherms, and the kinetic behavior are examined. The maximum CO2 uptakes at 30 °C and 15 vol% CO2 are 8.3 mg/gfiber for SiC-PEI and 102.2 mg/gfiber for CNT-zeolite. A lab-scale module is designed and used to determine the CO2 capacity of a fiber bundle. The energy requirement to heat such a fiber bundle from ambient temperature to 80 °C is 3.1 J/gFiberK (SiC-PEI) and 15.8 J/gFiberK (CNT-zeolite). To investigate the suitability of the fibers for real process applicability, a mathematical model is established and simulation results are presented and discussed. The two different approaches prove to be viable options for CO2 separation. They are not limited to CO2 capture but can be expanded to other gas separation tasks.

Expression of zinc-finger protein X-linked, ZFX, is associated with enhanced survival in patients with breast cancer.
Authors: Mamoor Shahan
Published: March 2020

We mined published tumor transcriptome data with paired survival data to discover genes associated with survival outcomes in breast cancer (1, 2). We found that the zinc-finger protein X-linked ZFX (3, 4) was among the genes most differentially expressed in both primary and metastatic tumor tissues when comparing tumor transcriptomes based on survival at 24 months. ZFX expression was significantly higher in the metastatic tumors of patients surviving greater than 24 months, suggesting that increased ZFX expression confers a survival benefit to patients with stage IV metastatic breast cancer.

This report presents information on the design and validity of the Batería Neuropsicológica Digital Infantil (BANEDI - in English Digital Developmental Neuropsychological Test Battery) based on data collected from a sample of 988 children/adolescents in Montevideo, Uruguay and Buenos Aires, Argentina. Building on recent contributions from cognitive neuropsychology, this instrument aims to assess the neuropsychological development of children and adolescents aged 4 to 15 years and attending Preschool to 3rd year of Secondary school in the region of Río de la Plata. BANEDI intends to be a clinically useful and scientifically rigorous tool to collect information on the following eight cognitive domains: memory, attention and executive functions, theory of mind, metalinguistic skills, oral language, visual-spatial skills, written language and mathematical skills. It consists of a total of 75 subtests and two questionnaires for parents and teachers.In this report we provide information on the results of item parameter analyses of the subtests included in the battery, as well as evidence on the content, criterion and developmental validity of BANEDI. To conclude, results reflect that BANEDI meets the criteria to ensure psychometric quality and can therefore be used to complete a valid estimation of the neuropsychological functioning of children/adolescents aged 4 to 15 years and attending Preschool to 3rd year of Secondary school.
“The COVID-19 Generation”: A Cautionary Note
Authors: Rudolph Cort , Zacher Hannes
Published: March 2020

With COVID-19 presenting as a global pandemic, we have noticed an emerging rhetoric concerning “the COVID-19 Generation,” both anecdotally and across various media outlets. The narratives advanced to support such rhetoric have distinct implications for the study of work, aging, and retirement. In this commentary, we review this emerging issue and present evidence against attempts to define “the COVID-19 Generation” as a new construct along conceptual, methodological, as well as practical lines, with a specific focus on identifying real dangers associated with investigating and potentially managing a new generation associated with this pandemic. We strongly caution against the adoption of “the COVID-19 Generation” as a concept of study and instead offer several suggestions to researchers, organizations, and practitioners seeking answers to complicated questions about links between COVID-19 and various processes relevant to work, aging, and retirement during this time of uncertainty.
Tools of the trade: Estimating time-varying connectivity patterns from fMRI data

Published: March 2020

Given the dynamic nature of the brain, there has always been a motivation to move beyond “static” functional connectivity, which characterizes functional interactions over an extended period of time. Progress in data acquisition and advances in analytical neuroimaging methods now allow us to assess the whole brain’s dynamic functional connectivity (dFC) and its network-based analog, dynamic functional network connectivity (dFNC) at the macroscale (mm) using fMRI. This has resulted in the rapid growth of analytical approaches, some of which are very complex, requiring technical expertise that could daunt researchers and neuroscientists. Meanwhile, making real progress toward understanding the association between brain dynamism and brain disorders can only be achieved through research conducted by domain experts, such as neuroscientists and psychiatrists. This article aims to provide a gentle introduction to the application of dFC. We first explain what dFC is and the circumstances under which it can be used. Next, we review two major categories of analytical approaches to capture dFC. We discuss caveats and considerations in dFC analysis. Finally, we walk readers through an openly accessible toolbox to capture dFC properties and briefly review some of the dynamic metrics calculated using this toolbox.

This paper has now been published in MetaPsychology: https://doi.org/10.15626/MP.2020.2626 Please cite the published article rather than the preprint doi. A rigorous field of research is constructed on reproducible findings that allow researchers to confidently construct hypotheses and build theories from accessible literature. As a nascent area of research, the study of Autonomous Sensory Meridian Response (ASMR) has the opportunity to become such a field through the adoption of transparent and open research practices. In this paper I outline five such practices that can help achieve this aim: Preregistration, sharing data and code, sharing materials, posting preprints, and collaboration. Failing to adopt such principles could allow the proliferation of findings that are irreproducible and delay the progress of the field. Submitted to Meta-Psychology.

The Psychology of Morbid Curiosity: Development and Initial Validation of the Morbid Curiosity Scale
Authors: Scrivner Coltan
Published: March 2020

The success of horror films, popularity of true crime, and prevalence of violence in the news implies that morbid curiosity is a common psychological trait. However, research on morbid curiosity is largely absent from the psychological literature. In this paper, I present a novel psychometric tool for assessing morbid curiosity, defined as a motivation to seek out information about dangerous phenomena, and use it to investigate the psychological nature of morbid curiosity. In studies 1 and 2 (n_total = 1370), the Morbid Curiosity Scale was developed and its relationship to personality was assessed. Morbidly curious individuals were rebellious, socially curious, and low in animal reminder disgust. Study 3 (n = 317) demonstrated that trait morbid curiosity is stable over 4-6 weeks and that morbidly curious individuals prefer movies where threat is a central theme. In Study 4 (n = 137), participants were presented with a choice between a morbid stimulus and a highly controlled non-morbid stimulus. Morbid curiosity predicted over half the variance (r2 = .53) in decisions to further investigate a morbid stimulus. These four studies provide evidence that morbid curiosity is a normally occurring psychological trait that can be accurately assessed using the new 24-item Morbid Curiosity Scale.
Bayesian Decision Theory and Navigation
Authors: McNamara Timothy P. , Chen Xiaoli
Published: March 2020

Spatial navigation is a complex cognitive activity that depends on perception, action, memory, reasoning, and problem solving. Effective navigation depends on the ability to combine information from multiple spatial cues to estimate one’s position and the locations of goals. Spatial cues include landmarks, and other visible features of the environment, and body-based cues generated by self-motion (vestibular, proprioceptive, & efferent information). A number of projects have investigated the extent to which visual cues and body-based cues are combined optimally according to statistical principles. Possible limitations of these investigations are that they have not accounted for navigators’ prior experiences with or assumptions about the task environment and have not tested complete decision models. We examine cue combination in spatial navigation from a Bayesian perspective and present the fundamental principles of Bayesian decision theory. We show that a complete Bayesian decision model with an explicit loss function can explain a discrepancy between optimal cue weights and empirical cues weights observed by Chen, McNamara, Kelly and Wolbers (2017) and that the use of informative priors to represent cue bias can explain the incongruity between heading variability and heading direction observed by Zhao and Warren (2015b). We also discuss Petzschner and Glasauer’s (2011) use of priors to explain biases in estimates of linear displacements during visual path integration. We conclude that Bayesian decision theory offers a productive theoretical framework for investigating human spatial navigation and believe that it will lead to a deeper understanding of navigational behaviors.

Underground pipeline stresses caused by damage near anchor mounting
Authors: Struk A. B.
Published: March 2020

The article considers the issues of underground pipeline strength, which are operated in geological or technogenic complication conditions (movements of indigenous soil in the tectonic fault zone, mutual displacements and rotations of rock blocks, etc.). The work aims at studying of a mobility limitation effect of a pipeline anchorage imposed on the stress state in the pipe wall in the site of a local damage foundation. The pipeline static was investigated in a geometrically linear formulation, modeling it with a tubular cross-section, and with a momentless cylindrical shell for straight issues. The interaction of the pipe with a dense base through soil backfill was described by the hypothesis of Winkler's elastic layer. The deformation of the anchored pipe caused by base local continuity disturbances was studied, which was modeled by the given jumps of longitudinal displacement and the block angle of rotation. This approach makes it possible to evaluate the strength of long underground communications not on the external load from the ground, which is usually unknown, but according to the observed parameters of riverside movements. The limiting state of the pipeline under the internal pressure of the transported product and under additional loading from kinematic perturbation was investigated by the energy theory of strength. The authors formulated boundary value problems for differential tensile-compression equations and torsion of a straight bar with discontinuous right-hand sides. On the basis of analytical solutions to the problems, the effect of normal separation crack damage, foundation blocks convergence and their turn around the axis of the pipe on the stress-strain state of the pipeline was studied. Plots of displacement distribution, angles of rotation and equivalent stresses of von Mises are constructed depending on the magnitude and direction of the mutual displacement and reversal of the riverside at different distances from the anchor to the base defect. It has been found that overlapping anchors in the form of anchorage leads to a significant increase in the equivalent stresses in the pipe. It has also been found that for pipes under internal pressure, the approximation of the base blocks is more dangerous than their divergence.
Solid Biofuel Production Perspectives in Ukraine
Authors: Panchuk М. V. , Semianyk І. М. , Mandryk I. O,
Published: March 2020

The reserves of fossil fuel resources in Ukraine are limited, that is why the usage of solid biofuel from renewable raw materials is one of the most important factors of state energy policy directed at the preservation of traditional fuel and energy resources and improvement of the environment condition. The analysis of biological resources is made in this paper, and it is determined that Ukraine has a sufficient potential which is available for energy production and constitutes around 29 million tons of equivalent fuel. Energy crops are an important resource therewith. A potential yield of solid biofuel from perennial energy crops can constitute approximately 35.8 million tons per year. It is shown that raw biomass has a number of disadvantages: low energy density, unstable granulometry, wide spread of moisture content, and low bulk density which are the main problems for its storage and transportation. In order to increase consumer performance properties of biomass, the granulation process is suggested to be used. The implementation of granulation process will allow to eliminate the shortcomings of biological raw material and to transform it into a high-efficiency fuel.  One of the most important conditions of effective and profitable functioning of granulated biomass production is the availability and regular supply of raw materials. Therewith, for Ukraine's conditions it is worthwhile to use sets of high-power equipment for its operation both in the places with high concentration of raw materials and small mobile units which can work in stationary conditions and move to the places with sufficient amount of raw materials decreasing the costs of biomass transportation to minimum. At the same time, there is a need in developing new homeland elaborations, both complex process lines and individual equipment units for different capacities.   The paper determines the main directions of using granulation products among which are: combustion in pellet boilers, common combustion with coal, and gasification of granulated biomass for obtaining motor oils. It is mentioned that the application of granulation technologies solves not only the energy problems but also a set of other problems: ecological, agricultural, forestry and social ones.
Improving the efficiency of oilfield electric power distribution
Authors: Yu. F. Romaniuk Yu. F. , Solomchak О. V. , Hlozhyk М. V.
Published: March 2020

The issues of increasing the efficiency of electricity transmission to consumers with different nature of their load are considered. The dependence of the efficiency of the electric network of the oil field, consisting of a power line and a step-down transformer, on the total load power at various ratios between the active and reactive components of the power is analyzed, and the conditions under which the maximum transmission efficiency can be ensured are determined. It is shown by examples that the power transmission efficiency depends not only on the active load, but also largely on its reactive load. In the presence of a constant reactive load and an increase in active load, the total power increases and the power transmission efficiency decreases. In the low-load mode, the schedule for changing the power transmission efficiency approaches a parabolic form, since the influence of the active load on the amount of active power loss decreases, and their value will mainly depend on reactive load, which remains unchanged. The efficiency reaches its maximum value provided that the active and reactive components of the power are equal. In the case of a different ratio between them, the efficiency decreases. With a simultaneous increase in active and reactive loads and a constant value of the power factor, the power transmission efficiency is significantly reduced due to an increase in losses. With a constant active load and an increase in reactive load, efficiency of power transmission decreases, since with an increase in reactive load, losses of active power increase, while the active power remains unchanged. The second condition, under which the line efficiency will be maximum, is full compensation of reactive power.  Therefore, in order to increase the efficiency of power transmission, it is necessary to compensate for the reactive load, which can reduce the loss of electricity and the cost of its payment and improve the quality of electricity. Other methods are also proposed to increase the efficiency of power transmission by regulating the voltage level in the power center, reducing the equivalent resistance of the line wires, optimizing the loading of the transformers of the step-down substations and ensuring the economic modes of their operation.

This article considers usage of blue-green algae as biomaterials for creation of motor biofuels. Proliferation of blue-green algae leads to water rotting, destruction of aquatic ecosystems and destruction of rivers and lakes that is why clearing of water bodies from blue-green algae is an urgent task. The object of the study is effect of blended biodiesel fuels from blue-green algae on the environmental and energy performances for the diesel engine. The purpose of the work is experimental study of changes of power and ecological characteristics of automobile diesel engines using petroleum diesel and their mixtures with biofuels derived from blue-green algae. Methods of research are experimental, laboratory ones. Laboratory researches were carried out on an experimental installation based on the serial diesel engine D21A1. As a result of performed experimental researches dependences of changing of the effective engine power on the use of diesel fuel and a mixture of diesel fuel with the received bioactive supplements based on methyl esters of the lipid fraction of blue-green algae Chroococcfles in the amount of 5, 10 and 20 % were established. It has been experimentally established that the effective power of an engine using a mixture of diesel fuel with the derived bioactive compounds based on methyl esters of the lipid fraction of blue-green algae Chroococcfles in the amount of 5, 10 and 20 % will decrease by an average of 0,9, 1,8 and 3,5 %. It has been experimentally determined that the content of carbon monoxide in the use of a mixture of diesel fuel with the derived bioactive compounds based on methyl esters of the lipid fraction of blue-green algae Chroococcfles in the amount of 5, 10 and 20 % will decrease by an average of 6,5, 13,9 and 28,7 %. The obtained results allow to optimize the choice of fuels for power systems of internal combustion engines and to reduce emissions of harmful substances in exhaust gases of automobile diesel engines.
Prospective types of alternative fuels for internal combustion engines

Published: March 2020

Currently, the disposal and recycling of the alcohol industry products creates a number of difficulties due to the lack of well-established recycling lines in Ukraine. Since 1998, eight enterprises of the state-owned concern Ukrspirt have been converted to produce high-octane oxygen-containing additives (CFCs) for ethanol-based fuels to organize the processing of waste from the alcohol industry. During this time, they produced 28.2 thousand tonnes of CALs, but CALA enterprises face great difficulties in selling their products, as they are new and expensive. The influence of fusel oil additives on commodity fuels on the main physical and technical indicators of the obtained alternative fuels is considered in the paper. According to the results of studies of octane number, we have established the optimal compositions of fuel mixtures of fusel oils with gasoline A-80 can contain up to 10% of the latter. For mixtures of fusel oils with diesel fuel by cetane number, their optimum content in diesel fuel is from 4 to 10% by volume. But, according to the trends of the development of diesel engines, the compression ratio increases, which allows the use of diesel fuel with higher cetane number, and therefore it is possible to raise the content of fusel oils in diesel fuel to 12%. According to the results of studies of the environmental performance of the ZIL-130 engine when fusel oils are added to commercial gasoline in an amount of 2 to 10% vol. the CO content in ICE exhaust gases decreases by 9.3%, fuel consumption increases by 6.5%, hydrocarbons by 10.2% and nitrogen oxide by 16.9%. As a result of increasing the content of fusel oils in diesel from 0 to 6%, there is an increase in mass flow rate of fuel to 6.1%, an increase in the concentration of hydrocarbons to 10% and nitrogen oxides by 1.9% in the exhaust gases of the engine D21A1. Thus, as we see today, along with traditional fuels for internal combustion engines, it is possible to use their alternative substitutes quite efficiently both in their pure form and in mixtures with them. There are all prerequisites for this in Ukraine and the region, the only question is the financing of these projects.
Regularities of Control of Mechanized Pulse-Arc Welding Process for Ensuring its Stability
Authors: Maksymov S. Yu. , Shlapak L. S. , Havryliuk А. А. , Semianyk І. М. , Onyskiv V. А.
Published: March 2020

Mechanized arc welding in protective gases with short circuits (s.c.) is performed at moderate values of the welding current (up to 180 ... 220 A) and at the relatively low voltage (18 ... 24 V) on the arc. The main disadvantage of the process is spattering when melting an electrode metal and when transferring it to a weld bath. The elimination of disadvantages is possible through the implementation of a controlled transfer of molten electrode metal to a welding bath - due to the pulsed nature of arc burning.  At pulse-arc welding (PAW), one of the main methods of increasing the efficiency of the process is to limit the maximum value of the short-circuit current Imax s.c. by increasing the inductive resistance L in the arc-welding circuit. Proceeding from the features of mechanized arc welding, the purpose of the research is to specify the influence of the velocity of the growth of the welding current vс during the s.c. on the arc stability. The implementation of experimental work presupposes surfacing on a plate with the programming of the operating mode of the inverter at different values (9, 12, 15, 18, 21, 24, 27, 30) with the frequency f = 25 Hz and a pulse ratio C = 2. While analyzing oscillograms of welding current and processing their records, it was established that a decrease of the velocity of the welding current growth leads to a significant limitation of the maximum value of the short-circuit current. The statistical processing of the momentary values of the welding current shows that the increase in the velocity of current growth vс starting with vс = 1.23 kA / s to vс = 50 kA / s makes the average short-circuit duration 10 times shorter. At the same time, the average frequency of short circuits grows more than twice. The increase of vс leads to the destabilization of the pulse process and this is reflected in the 30-times increase of the average frequency of arc break. The increase of the energy indexes of the PAW to the Iav. = 220 ... 225 A, Uav. = 24.5 ... 25.9 V, Q ≈ 7.9 ... 8.0 kJ / cm led to the changes in the parameters which characterize the process of pulsed welding with short circuits. There is a sharp decrease in the average frequency of short circuits (2 ... 3 times as rarely) and the average duration of s.c. (twice shorter).

Since the mining and oil and gas industries play a decisive role in the Ukrainian economy, the adequacy and proper assessment of the accuracy of the monitoring is of great national importance. A mathematical model for the measurement of MSCs is constructed, which determines the sequence of mathematical operations that must be performed to obtain the quantitative characteristics of the objects of control. If there is a function that is a solution and that describes the object of the MSC, then it is a reduction to the ideal MSC. The solution of the problem of reduction (synthesis) MSC is realized by the choice of design and is provided with such a connection between the signals at its input and output MSC, which leads to the best results. This formulation of the problem of reducing the MSC has several disadvantages. The MSC measurement result is always influenced by a number of minor factors. Their effect leads to the fact that the measured value of a certain value is different from the value predicted by the model of measurement of the ISC on the noise (experiment error), which is random. The noise level of MSCs has a significant effect on the result of mathematical processing, and the less the noise, the better the result of the reduction of MSCs. Previously, the task of instrumentation was to create an MSC that provides the least distortion of the measurement results, while using mathematical methods to reduce instrumentation the task of reducing instrumentation noise is MSC. The given  solution is realized by the choice of design and is provided with such a connection between the input and output signals, which leads to a decrease in the level of random noise MSC. The description of MSC enhancement has the instability of the solution of the equation with respect to the initial data errors, which is a property of almost all integral equations and does not depend on the method of their solution. The proposed mathematical method of reduction of the mobile control system (MSC) as one of the variants of regularization of the incorrectly set problem arose and was further developed under the influence of the ideas of academician AN Tikhonov and Professor Yu.P. Pytiev .  The author suggests taking a different look at the control tasks and the accuracy of assessing the accuracy of MCSs by reducing the level of random noise. The author proposed the implementation of the MCS by choosing a design and providing such a connection between the signal at its input and output, which leads to the best results in solving reduction problems. The author proposed an adaptable model of MCSs using modern ideas and mathematical methods.

Thermographic control of electrical equipment allows you to draw preliminary conclusions about the technical condition of insulation, contact joints, windings, structural elements and cooling systems of electrical equipment of voltage classes 0.4 ÷ 750 kV. However, it should be borne in mind that the results of temperature measurement and assessment of the thermal state of electrical equipment are influenced by such factors as: environmental conditions, qualifications of personnel performing thermographic control and data interpretation, the need to improve regulatory documents for assessing the thermal state of electrical equipment and develop unified algorithms analysis of the results of thermographic examinations and gradation of the development of defects in electrical equipment.

Modern research in the field of thermographic control of electrical equipment is developing in several directions, namely: the use of automated (stationary or mobile) systems for collecting thermographic data; development of algorithms for processing thermal images that reduce the influence of extraneous noise on the values of the measured temperatures, select the image of the object being examined, select the optimal level of contrast of the thermal image to detect thermal anomalies; using statistical processing of thermal fields of thermal monitoring objects and making decisions about the thermal state of equipment using neural networks, machine learning and expert knowledge. Automation of the analysis of thermographic control data is an urgent scientific and practical task, the solution of which will improve the quality of maintenance, repairs, extension of the operating life and operational management of electrical equipment in conditions of a significant level of aging of the main production assets of electric companies and change of generations of staff.

ORGANIZATIONAL AND ECONOMIC MECHANISMS TO SUPPORT INNOVATIVE DEVELOPMENT AT THE REGIONAL LEVEL
Authors: IERMAKOVA О.А.
Published: March 2020

Topicality. One of the problems of the state innovation policy in Ukraine is the abolition or suspension of financial privileges for the subjects of innovation activity due to the lack of transparency of the mechanisms of their distribution. However, complete rejection of state financial support o innovation, that is one of the most widespread instruments of innovation policy in the world, does not correspond with the interests of innovative development of the state. As a solution of this problem at the regional level could be the mechanism of financial support for innovative projects on a competitive basis.
Aim and tasks. The purpose of the article is to develop organizational and economic mechanisms of innovative development at the regional level and to discover the source of formation of their financial support.
Research results. The article proposes a mechanism for competitive selection of innovative projects to receive funding from local budgets, which, unlike the existing ones, is as transparent as possible, ensures competitiveness among applicants and takes into account the priorities of innovative development of a particular region through the following procedure: the committee for selection of innovative projects is formed on the principles of participatory involvement of representatives of all stakeholders - authorities, business, science, education, community, determines the terms of competition and announces the competition; the competition is open to anyone who has ideas on the announced theme; the selection procedure occurs with maximum transparency and the announcement of the criteria, the selected projects receive funding from the local budget at the expense of the development budget; audit. It is envisaged that economic support for the competitive selection of innovative projects is carried out on the basis of partnerships and financial support from local budgets. The following mechanisms have been proposed: public-private partnership financing through equity participation; granting tax exemptions for other taxes paid to regional budgets; investment-oriented tax benefits, which provide for the exemption from income tax on the financial results of enterprises that are not withdrawn from business and reinvested in innovative projects.
Conclusion. Implementation of the proposed mechanisms will ensure transparency of the project selection process, competitiveness among applicants, financial support from different sources and taking into account the priorities of innovative development of a particular region.
The shamanistic universe of Central Asian nomads: wolves and she-wolves
Authors: Kulsariyeva Aktolkyn , Sultanova Madina , Shaigozova Zhanerke
Published: March 2020

The article deals with the semantic nature of the images of a wolf and a she-wolf in the shamanistic natural philosophy of the nomadic Turkic-speaking population of Central Asia. The focus here is an archetypal image of a wolf and a she-wolf as ancestors, defenders and guardians of the Turks’ cultural code – one of the most powerful, large-scale and sustainable Eurasia cultures, united by common linguistic roots and mentality. The majority of studies of the semantics of zoomorphic characters in Central Asian cultures focus on a wolf, while a she-wolf’s image at most is in the sidelines, although it appears in almost all Turkic genealogical legends as one of the central characters. The authors are of the opinion that the study of natural philosophical underpinnings of images of a wolf and a she-wolf from the point of view of traditional shamanistic ritualism can expand the long-held beliefs about transformation and specificity of functioning of mental values in the cultural sphere of modern society.
Od ludu wybranego do narodu cierpiącego, wygnanego, tułaczego. Komplementarność motywów w literaturze staroserbskiej
Authors: Lis-Wielgosz Izabela

The paper regards a problem of realization and function of the motifs of emigration and wandering that occur in a complementary arrangement in Old Serbian literature. They consist of a specific scheme of presentation and exegesis concerning the historical, religious and cultural reality. The motifs are a characteristic strategy of the expression of collective fate – the tragic experience of the Great Exodus in 1690. They find an extraordinary realization in brief literary form – the notations wherein the motifs establish a definite semantic collection, combined with many already consolidated ideas and ideological constructions. That collection is to met with a favourable response of the subsequent cultural phenomena and conceptions, creating a unique image of the Serbian community. Those phenomena constitute a sort of topic structure, based on the already established imaginative conceptions, especially the messianic image of the “chosen nation” and “nation-martyr” that create a new character of the Serbian community, or make the previous one concrete, henceforth described not only in the categories of election and martyrdom, but also of “emigration from the Turkish land”, wandering and homelessness in the land of Hungary.
