IDEATIONAL INSTITUTIONALISM: EXPLAINING INSTITUTIONAL TRANSFORMATIONS DURING A CRISIS
Authors:   National Research University “Higher School of Economics”, Onishchenko Anton
Published: September 2021

The role of agents' ideas in determining the direction of institutional transformations is often underestimated; this is especially true if one is analyzing the formation and/or reformation of institutional design during a crisis when the significance of other factors may decrease. Institutional approaches of historical institutionalism and rational choice institutionalism are not always able to adequately measure the impact that agents' ideas have on institutional transformations. Ideational institutionalism, on the contrary, allows one to focus on these ideas, as well as to analyze both ideas’ effect on emerging institutions and the impact of an agent’s ideas on ideas of other agents. Furthermore, ideational institutionalism in the form presented in the article proposes to move away from the perception of ideas exclusively as intersubjective and to separately study the ideas of each decision-maker; this allows one to assess the role of a particular agent in the formation of institutions. This approach is promising, in particular, for the analysis of the institutional changes that occurred in the post-Soviet countries after the collapse of the Soviet Union. The article discusses the main characteristics of the ideational approach and the framework of its use on the example of institutional changes in the Republic of Belarus in the 1990s.

Published: September 2021

The integer is a basic concept in studying arithmetic and algebra. However, students still frequently experience misconceptions, especially in negative integer, count operations. Traditional games are activities that are often carried out by students in coastal areas so that they are relevant to be used as a tool to construct learning trajectories in solving integer word problems. The aim of this study is to produce a learning trajectory that can be used to solve integer word problems using traditional games. This study used a design-based research. Participants in this study were five grade sixth elementary school students. There are 6 sub-topics studied, i.e., the concept of negative integers, sequence integers, addition and subtraction operations, division and multiplication operations, mixed count operations, and solving problems related to integers. The results of this study obtained student learning trajectories for each sub-topic including the free play, collecting data from the game results, making mathematical relationships, building concepts, and applying them to various problems. Students are able to do problem-solving based on the sequence of tasks but require intervention so they can apply it to other situations without engaging in activities. Further research is required for more in-depth exploration on thinking process, instruction types, and behaviours that students might display independently without using traditional games in solving integer word problems.
A SARS-COV-2 vírus magyarországi terjedésének ágens alapú modellezése – az első járványhullám tapasztalatai
Authors: Lennert József
Published: September 2021

A SARS-CoV-2 vírus okozta COVID-19 pandémia az eddigi egyik legnagyobb kihívás, amivel az emberiség a XXI. században szembe kellett, hogy nézzen. Jelen tanulmányban bemutatott kutatás az új típusú koronavírus-fertőzés első magyarországi hullámának tér- és időbeli lefutását modellezi, remélve, hogy hozzájárul a vírus terjedésének feltérképezéséhez. A modellezéshez ágens alapú módszertant használtam, az ágensek a magyar lakónépesség tagjait testesítik meg. A program a futtatás során 6, fertőzés átadására alkalmas társas érintkezési módot különböztet meg A népességet koruk és gazdasági aktivitásuk alapján 8 aktivitási csoportba osztottam. Az egyes aktivitási csoportok eltérő mértékben vesznek részt a definiált társas érintkezési formákban. A fertőzésterjedés vizsgálatához 12 forgatókönyvet alakítottam ki, amelyek eltérhetnek aszerint, hogy mekkora a feltételezett alap reprodukciós ráta, a külföldi forrásból származó fertőzések az ország mely részén jelennek meg, hogy életbe lépnek-e a modellfuttatás során fertőzést korlátozó szabályok, és ha igen, a fertőzés kezdetétől számítva milyen késéssel. A korlátozásokat nem tartalmazó forgatókönyvek az elvárható exponenciális görbét rajzolják ki, 6 napos duplázódással. A kapott eredmények a munkahelyen történő fertőzések elsődleges szerepét mutatják a fertőzés továbbterjesztésében, ezt követi az iskolai, illetve a háztartáson belüli fertőzésátadás. A modellezés területi eredményeinek kiértékelése alapján a fertőzés elsősorban a nagy földrajzi távokat is áthidalni képes hierarchikus diffúzióval, másrészt az ingázási kapcsolatokon keresztül terjed a települések között. A bevezetett korlátozások elsősorban a hierarchikus diffúziós terjedést gátolták meg, és megnövelték a háztartáson belüli fertőzésátadás relatív jelentőségét. A kapott eredmények alapján a korlátozások elégségesnek bizonyultak az exponenciális növekedés megtörésére mind az alacsonyabb, mint a magasabb alap reprodukciós rátát tartalmazó forgatókönyvekben. A kapott eredményeket a hivatalos fertőzésszámokkal és a H-UNCOVER országosan reprezentatív felmérés tapasztalataival is összevetettem.
Indian culture as a peculiar experience of cultural identification
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Shynkarenko O. V.
Published: September 2021

The article is dedicated to the consideration of the phenomenon of India as an indicative example of the productivity of the spiritual and ideological potential immanent in its historical heritage and social practices, as the basis of the identification process as an affirmation of unity for such a culturally diverse region. The bringing to light of the cultural identity of India, reconstructed at one time in the research of the patriotic intellectual elite, has become that productive self-determination ("the discovery of India"), which, having played its role in preserving its authenticity under foreign cultural pressure, remains relevant for successful self-development in complex globalization processes of multicultural world community. The principles of "synthesis, assimilation, development", "search for truth in a non-violent way", "unity in diversity" became the cultural codes that make up the core of the identification of the Indian cultural community. Through the actualization of the ancient spiritual tradition, the Indian reformers realized the inherent in the Indian philosophical and spiritual tradition the ability to synthesize, on the one hand, with the cultural layer of the past, and, on the other hand, with those innovations, albeit another cultural, even opposite (European Christian tradition, rationalism) , which, under the condition of tolerant, without vain denial, perception (assimilation of experience, models of other peoples who came to the subcontinent), productively complemented the cultural capacity of India. The modern large-scale globalization of socio-cultural life accentuate the importance of the problem of cultural identification as a process not only of individual identification (identity) with the world of one's community, but also of collective self-determination in the formation and preservation of a unique cultural whole. The threat of erosion of meaningful semantic, value, symbolic orientations of unity actualize cultural studies of this problem. The culture of India provides a vivid experience of long-term preservation of the cultural integrity known for its ethnocultural diversity, the complex socio-historical conditions of the region's existence, which appears to be very productive both for theoretical studies of cultural regionalism and for further cultural studies of identification.
Material culture as a method of urban design research: modern challenges
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Butsykina Y. O.
Published: September 2021

Article discusses material culture as one of the thorough ways to determine the methodological basis for the cultural study of design, design practices and, including urban design in the world and in Ukraine. The article turns to the researchers who initiated the actual exploration of material culture outside of archeology and cultural anthropology, which will eventually lead us to modern views on material culture as a relevant approach in culturological analysis of the design of objects, objects of urban space – in particular. The article provides the actualization of this issue in the application to the culturological study of urban design itself, taking into account its specifics. It outlines some compelling arguments as to why the discourse of material culture is becoming increasingly relevant in the study of urban design and culturological research in particular. A number of approaches is shown within which this combination becomes relevant. Especially given the design of Ukrainian cities and its cultural research, where the need to overcome the dichotomy of spiritual and material culture has long been ripe.

Published: September 2021

The article analyzes modern design practices based on symbolic and ornamental motives of folk art and their modern actualization in ethno-artistic areas, reflecting the relationship of traditional aspects with innovative, symbolic translation of cultural experience in time and space, creating symbolic value images, enhancing emotional environment and creating new narratives. Symbols, as the basis of the existence of the people, reflect the ethno-national aspects of culture, is an opportunity to find yourself at the level of relationship with your people, your nation, traditions. The appeal to archetypes is a special methodological perspective in which the meaning of the future is created due to the transformation of the past into a symbol. What is relevant in modern Ukrainian realities is that the whole cultural paradigm is being reconsidered and new ways of national identification are being sought. Embroidery is marked by a special color and incredible ornamentation, complex performance technique, which is reflected in the symbols of sociocultural practices, immersing in the depths of traditional norms and values that encourage to feel, assimilate, preserve and transmit. In modern domestic discourse, design practices are thought of as aimed at transforming the cultural environment into the integrity of cultural and natural components. They serve as a basis for forming an idea of the world and building harmonious relationships with the world. And the use of symbols-amulets and a certain emotional color is a special process of self-identification and the foundation for the revival of national culture and spiritual values, seeing their own place in the global cultural and artistic space. Therefore, the use of ornamental symbols in design practice is the basis for the revival of national culture and spiritual values and the formation of a new promising direction of Ukrainian design. Among the spiritual heritage of Ukraine with its color and incredible ornamentation, complex technique is embroidery, which is reflected in the symbols-codes of modern socio-cultural practices.
Psychoanalysis: from clinical medicine to clinical anthropology
Authors: Martynov Innokentiy A.
Published: September 2021

Psychoanalysis has met highly emotional resistance since its very inception in the late 19th century. A year never passes without somebody proclaiming the death of psychoanalysis. Despite such tendency, psychoanalysis is far from its decline. It is gathering new endorsers rapidly and is enhancing its positions in new geographical and cultural contexts. This article explores the possible origins of such resistance in the Russian mental health field. The author suggests that it is caused first and foremost by disciplinary discrepancies one may observe by studying the discrepancies between medical and psychoanalytical semiotics as a foundational method of the disciplines. Such view allows to explicate some problematic issues and conflicts in the Russian mental healthcare community, as well as to suggest what holds it back from obtaining significant public influence.
Non-psychotic depression and the social burden of illness
Authors: Petrova Natalia N. , Shatil Mikhail M.
Published: September 2021

The burden of depression is increasing worldwide, caregivers are seen as a psychologically vulnerable group, and the social burden of non-psychotic depression remains unexplored.
The aim of the study was to examine the clinical and functional characteristics of non-psychotic depression and the burden of family members of patients most involved in the interaction with patients. The study objectives included analysis of quality of life and co-occurring behavior of patients relatives as characteristics of their psychosocial adaptation.
Methods. We used clinical and scales assessment of depression level, quality of life, subjective distress level, and coping behavior features.
Results. Nonpsychotic depression was detected approximately half a year after the onset of symptoms, and in more than 40% of cases not by psychiatrists, self-treatment was typical. Impairments in social functioning in non-psychotic depression patients affected more in the areas of socially useful activities and social relationships, predominantly in non-working patients. 62.96% of patients rated relationships with loved ones as good, and 82.6% rated support from relatives in connection with the illness as adequate. In 60.87% of cases, there were psycho-traumatic microsocial factors. Spouses (45.5%) prevailed among supportive relatives, of whom 60% were employed, and limitation of labor activity due to the relatives illness was not characteristic, and material losses were insignificant. Supportive relatives more often than their sick relatives assessed the relationship with the sick as good (81.8%). In about 91% of cases, the attitude toward the mental illness of the relative was adequate, which exceeds the subjective assessment of patients with non-psychotic depression. The close relatives of the patients had decreased quality of life, which was mediated by severity of depression, higher than average level of distress related to mental disorder of the loved one (64,59,34 VAS scores). The structure of coping in supportive relatives is characterized on the whole by prevalence of constructive and relatively constructive coping-strategies, the most problematic being the emotional sphere of coping behavior.
Conclusion. Even mild to moderate non-psychotic depression is associated with the presence of social burden of illness, covering not only the patients themselves, but also their family members, which necessitates psychologically corrective work with supportive relatives.

Published: September 2021

Se ha demostrado que la rehabilitación bilateral asistida ayuda a los pacientes a mejorar su capacidad del miembro parético y promover su recuperación motora tras sufrir un accidente cerebrovascular (ACV), especialmente en las extremidades superiores. La rehabilitación bilateral asistida por robot, basada en el control por EMG, ha sido abordada anteriormente en otros estudios para mejorar la movilidad de la mano, pero faltan soluciones integradas de bajo coste para el control biocooperativo en tiempo real de las plataformas de rehabilitación robótica. Este artículo presenta una solución integrada de EMG en tiempo real de bajo coste, de diseño propio, implementada en la plataforma RobHand (Robot para la Rehabilitación de la Mano), un exoesqueleto que soporta terapias bilaterales basadas en EMG. Se ha desarrollado un control por umbrales basado en EMG para RobHand, que detecta el gesto de la mano sana y lo replica en el exoesqueleto colocado en la mano parética.

Como alternativa a los laboratorios tradicionales, en los que los estudiantes interactúan con un sistema real cuyo uso tiende a estar limitado por el tiempo y/o el espacio, existe la posibilidad de emplear laboratorios “para llevar a casa” que constituyen un recurso didáctico más flexible. El presente trabajo describe la experiencia en la Universidad de Almería con una plataforma de este tipo que se ha empleado en estudios de grado y postgrado para la enseñanza de técnicas de modelado y control sobre un sistema termodinámico. Su aplicabilidad en otras asignaturas junto a la opinión positiva que se ha percibido del alumnado sugieren que esta podría ser una metodología con un prometedor recorrido por delante.

Authors: Pataro Igor M. L. , Gil Vergel Juan Diego , Americano da Costa Marcus V. , Guzmán José Luis , Berenguel Manuel
Published: September 2021

Uno de los aspectos esenciales en el diseño de un sistema de control consiste en garantizar su estabilidad en bucle cerrado. Este artículo presenta un controlador predictivo basado en modelo de horizonte infinito con compensación por adelanto y garantía de estabilidad en bucle cerrado para sistemas estables. La estabilidad del controlador se garantiza mediante los conceptos de solución recursiva y disminución asintótica de la función de coste. La técnica desarrollada se prueba en simulación usando como sistema de referencia un campo de captadores solares de placa plana. Además, se presenta una comparación con el mismo enfoque de control pero sin incluir la compensación por adelanto. Los resultados obtenidos demuestran que la estrategia propuesta mejora el desempeño del controlador rechazando correctamente las perturbaciones y manteniendo las características de estabilidad nominal, lo que asegura la convergencia en bucle cerrado tanto para los problemas de seguimiento de referencia como de rechazo de perturbaciones.

En este trabajo se propone una metodología para dimensionar el sistema de almacenamiento de un sistema híbrido con fotovoltaica (FV) para uso doméstico, a partir de predicciones probabilísticas de la producción solar. Se introduce para ello un modelo basado en Deep Learning que, a partir de estimaciones de la irradiancia pasada en el área que rodea la localización objetivo, obtiene las predicciones de distintos percentiles de la producción FV. El dimensionamiento se realiza mediante una optimización lineal que utiliza la función cuantil para garantizar, con un cierto nivel de confianza, que se satisface un perfil de demanda tipo. Finalmente, se introducen y discuten resultados en cuanto a la violación de restricciones que se produce con diferentes tamaños del sistema de almacenamiento mostrándose que, cuando este es superior a 3 h a potencia nominal de la instalación FV, las restricciones se satisfacen en más del 99% de las ocasiones.

Published: September 2021

En este trabajo se propone un controlador con estimación de parámetros enfocada a sistemas no lineales, desconocidos y cambiantes en el tiempo. Se presenta un algoritmo de aprendizaje en línea para estimar las ecuaciones del sistema y un controlador que usa esta información para estabilizar la planta. Para ello, se han combinado un observador no lineal y un estimador de parámetros con técnicas de optimización dispersa. En el algoritmo hay dos fases diferenciadas: la fase de aprendizaje, donde se aprenden en línea las funciones desconocidas, y la fase de ejecución, donde se controla la planta con unos objetivos preestablecidos. El algoritmo propuesto es capaz de decidir de forma autónoma en qué fase se encuentra, mediante una métrica de aprendizaje. Este algoritmo se ha validado por simulación numérica en una planta roto-magnet.

The reject of the reverse osmosis water treatment process (aka brine, concentrate, ROC) is a mixture of salts that are dissolved in high salinity water. The ROC is classified as an industrial waste by the U.S. Environmental Protection Agency and can face regulatory limitations on disposal. State-of-the-art of ROC disposal includes deep-well injection, surface discharge to rivers, discharge to the ocean, and evaporation ponds. In this study, the feasibility of using Reverse Osmosis Concentrate as a low-cost Thermal Energy Storage (TES) medium is explored by a techno-economic analysis. The normalized cost of TES (cost per unit volume of stored thermal energy) is estimated through a series of cost analyses and is compared to the cost targets of the U.S. Department of Energy for low-cost thermal energy storage. It was shown that the normalized cost of TES using ROC salt content is in the range of $6.11 to $8.73 depending on ROC processing methods.

Published: September 2021

The Gross Regional Product (GRP) of Shandong ranks third in China, but its energy and coal consumption rank first. However, in the past studies, no effort was made to analyze the influence of Shandong energy conservation and emission reduction policies on energy consumption changes. To make up for this gap, the revised divisia index and the energy consumption structure methods were used in this study to analyze the driving force of changes in energy consumption in Shandong from 2005 to 2016. The results of this research show that: Firstly, the control of energy-intensive industries and strong energy conservation policies had become the main driving forces for energy density reduction. Secondly, the energy structure optimization policies only increased the proportion of hydro, nuclear and new energy production to replace a proportion of oil, but could not effectively reduce the consumption and proportion of coal. The continuous increase in coal consumption offset the energy conservation effect by key industries during the Twelfth Five-Year Plan period. It is clear that a reduction in the amount of coal used and an increase in the proportion of hydro, nuclear and new energy (especially in the industrial sector) is at the core of the energy problems in Shandong. Policy recommendations are proposed that are based on the findings of this study.

The main problem in studying the feasibility of solar systems is the enormous gap between theory and experimental radiation intensity, so to get accurate results there is a need for studying energy production in the site of the system empirically. In this study, the energy production of both fixed PV panel system and the system with single-axis tracking were empirically evaluated in Medina, Saudi Arabia. The two systems had the same 270 Wp PV panel. The fixed system was tilted by 23.5 degrees, and the single-axis tracker was tilted by 26 degrees. Both systems had an azimuth angle of zero degrees. A closedloop three-points controller was used to control the tracker with 120 degrees rotation range. The two systems operated simultaneously in July, and the data were collected for 14 days. The empirical results showed that the tracker increased the generated energy by 48.5% during the testing period. As a comparing method, a modified ASHRAE model was used to estimate the increase in the panel's energy output with and without the single-axis tracker, and RMSE and MBE were calculated. It's been found that the experimental energy generation is 10%, 5% less than the estimation of the modified model for the fixed system and the tracking system, respectively. Finally, based on the analysis, it's been estimated that the singleaxis tracker will increase the generated energy by 22.5% yearly in Medina.

In Spain, biomethane and biogas are still starting to be considered as an alternative to natural gas. A good way of promoting these renewable energies is supporting small and cheap treatment plants near to the place where the biogas is produced and where the biomethane can be used on site, fostering the circular economy. An easily usable simulation tool for selecting the best sequence of unit operations for treating biogas (based on adsorption, absorption, and membranes) has been designed. Pollutants modelled are CO2, CH4, NH3, SH2, CO2, O2, N2, H2O and siloxanes. This tool was used as first step to design a flexible and portable prototype for treating small flows of biogas as those produced in livestock which has been later built and is on operation.
Phytoplankton functional groups as environmental indicators at a high neotropical mountain reservoir in Colombia
Authors: Hakspiel-Segura Cristian , Barrios-Galván Betsy Paola , Pinilla-Agudelo Gabriel
Published: September 2021

Phytoplankton is a fundamental productive component of lentic ecosystems, which also directly reflects environmental variability. This study evaluated the dynamics of phytoplankton in response to the monthly variability of physicochemical properties of a neotropical high Andes reservoir, El Neusa, from July to October 2004. Samples were collected and analyzed for taxonomic identification to species or the lowest possible level and categorized in functional groups (FGs). A total of 111 species of phytoplankton belonging to nine classes and 20 FGs were recorded. Among these phytoplankton classes, Chlorophyceae (36 species), Euglenophyceae (13 species), Bacillariophyceae, (14 species), and Conjugatophyceae (25 species) were the most species-rich and highest in abundance. The overall phytoplankton abundance was largest in August (8.5×104 ±2.7 ×104 ind.L-1) and September (8.9×104 ±4.6×104 ind.L-1); however, the distribution of phytoplankton classes was not statistically different among sampling sites (Friedman-ANOVA; p>0.01)  Chlorella sp. (2.4×104 ±2.0×104 ind.L-1), and Chloromonas grovei (2.5×104 ±4.4×103 ind.L-1), belonging to functional group X1, were dominant, representing together between 54% and 78% of the average monthly abundance. Simple correlations and multivariate analysis between physicochemical variables and phytoplankton revealed that conductivity, pH, and total suspended solids had a key influence on the distribution of both dominant species and FGs. These analyses indicated that hydrological (precipitation and runoff) and water stability (stratification and mixing) conditions determined environmental changes and the selection of phytoplankton functional groups. The main features of the dominant FGs and the trophic state of El Neusa were also discussed.

Published: September 2021

A esporotricose é causada pelos fungos dimórficos do complexo Sporothrix. Atualmente se apresenta como um problema de saúde pública, principalmente considerando a falta de conhecimento sobre a patologia, o que acarreta atraso no diagnóstico. Dentro da perspectiva de promoção da saúde, o Núcleo de Apoio à Saúde da Família (NASF) constitui-se como peça-chave no desenvolvimento de ações que podem promover educação, prevenção e auxílio terapêutico à população. Diante do exposto, o objetivo deste trabalho foi avaliar a percepção do profissional do NASF acerca da esporotricose e sobre a importância da capacitação da equipe envolvida nesse problema de saúde pública no município de Vitória de Santo Antão - PE, no período de agosto a outubro de 2018. A pesquisa foi desenvolvida em três momentos que correspondem à aplicação de um questionário virtual,  ao desenvolvimento de ação de educação em saúde na forma de treinamento e à aplicação de um questionário presencial. Foi observado que 16 participantes (51,6%) não tinham conhecimento sobre a esporotricose. Posteriormente, foi realizada uma intervenção e aplicado outro questionário, a partir do qual se observou que 17 entrevistados (89,5%) afirmaram que grande parte do conteúdo abordado tinha aplicação nas ações da sua vida profissional. As informações advindas das avaliações permitiram identificar que os participantes da pesquisa não estavam familiarizados com a doença. No entanto, o aperfeiçoamento profissional por educação permanente em saúde é capaz de contribuir para o melhoramento do serviço prestado.

Introduction: Many occupations require prolonged standing during exercise, which is one of the most important causes of musculoskeletal disorders, causing pain and discomfort in the back, lower limbs, and especially the soles of the feet, resulting in improper distribution of pressure in the soles of the feet. Epidemiological studies also show a strong association between prolonged standing and pressure on the lower back and lower limbs. One of the ergonomic solutions to reduce the problems caused by long-standing activities is to correct the surface under the fee. Therefore, this study investigates the effect of ergonomic flooring and conventional flooring on the distribution of foot pressure in healthy individuals; based on that, the effect of using ergonomic flooring in comparison with conventional flooring, more appropriate distribution, and reduction of pressure in the sole can be determined.
Materials and Methods: This descriptive-analytical study was performed on 16 students with a mean age of 27.87±7.31 and a body mass index of 24.15±4.31. According to previous comparative studies and data analysis obtained from pilot samples, by considering the 95% confidence interval, the samples were determined by the convenience sampling method. Each participant was measured at eight anatomical points for one hour at two different surfaces of ergonomic and ordinary floor. Foot pressure distribution using a pedar-x device while the volunteers were barefoot. Data were analyzed by paired t-test and Wilcoxon using SPSS software.
Results: This study showed that the ergonomic flooring significantly reduced the mean pressure on the plantar pressure (p≤0.001). Also, there is a significant difference in the mean pressure of left and right legs in different anatomical points when using ordinary surfaces and flooring (p≤0.001).
Conclusion: There is a difference between the distribution of plantar pressure in ergonomic flooring and conventional flooring. Ergonomic flooring has better distribution than the ground and reduces the pressure on the sole during static activities.

A review of literary sources on the physical and mechanical properties of pearwood and its use as structural elements of furniture is given. The aerodynamic chambers, their advantages and disadvantages, as well as their modernization are considered. The use of impulse modes for drying hardwood is substantiated, including sawn timber from pear wood 50 mm thick, pilot drying of which began in the modernized URAL-72 chamber in 1999 at Intar LLC, Moscow. The moisture content of the wood samples and the value of internal stresses were controlled in accordance with GOST 16588. The process of impulse drying included from 9 to 12 steps, the temperature at the operating stage ranged from 45 °C to 72 °C. It has been proved that the use of pulse modes for drying pear timber saves up to 30% of electricity.

The results of research that was conducted in 2017 in the laboratory of the Department of Forest crops, breeding and dendrology of the BMSTU (Mytishchi branch) and in the Pravdinsky nursery of the Pushkin forest technical College of the Moscow region. The purpose of the study was to determine the effectiveness of the influence of low-frequency electromagnetic field (EMF) on laboratory and ground germination of common pine (Pinus sylvestris L.) seeds with low seeding characteristics. Samples of common pine seeds of the 3rd quality class were selected for the study (collection 2014). The seeds selected for the study were treated with low-frequency EMF using POSEP technology (pre-sowing seed treatment with an electromagnetic field) with a low-frequency generator Rost-Active. One part of the seeds was laid for germination in the laboratory in 4-fold repetition, the other was sown in the sowing Department of the Pravdinsky nursery in 3-fold repetition, control was served by unprocessed seeds. As a result of pre-sowing treatment of pine seeds, laboratory germination exceeded the control by 25 %, and approached the indicators for class I seeds. In the Pravdinsky nursery, the yield of 1-year-old seedlings increased by 16 %, and their height was 47 % higher than the control. The results of laboratory and field studies have demonstrated the high efficiency of pre-sowing treatment of common pine seeds using POSEP technology and its ability to restore the seed quality after long-term storage, increase the yield of seedlings and improve their biometric indicators.

The study results of coniferous stands and the description of stands in the southern taiga forests of the taiga zone within the Udmurt Republic (on the territory of the Yakshur-Bodya, Igrinsky and Kez forest districts) are presented. The climatic indicators of the study year are presented in comparison with the average long-term data for the studied areas. The taxational characteristics of forest stands are given, the indicators of the morphological profile, humidity, and cellulose-decomposing activity of forest litter are presented. Studies have shown that the cellulose-decomposing activity of forest litter depends on its moisture content, which is associated with the values of the basal area per hectar of stands in the studied sample areas. No differences in the indicator of cellulose-decomposing activity were found in the sample areas in the Igrinsky forestry. The highest values of this indicator were determined in the sample area No. 1 in the Kez forestry. The lowest values of the cellulose-decomposing activity of forest litter were observed in the sample areas No. 1 and No. 3 in the Yakshur-Bodya forest area. The physiological and biochemical parameters of Siberian spruce (Pícea obováta Ledeb.) were analyzed and compared in trees of good and satisfactory living conditions, which did not show statistically significant differences in the content of chlorophylls and carotenoids in the needles. A significantly high content of photosynthetic pigments and tannins in Siberian spruce conifers was found in the sample areas in the Igrinsky forest area. Similar results were obtained for individuals of a satisfactory living condition, with the exception of the content of tannins in conifers. It was found that the high content of chlorophyll a in Siberian spruce needles is usually accompanied by an increased content of tannins and a low concentration of ascorbic acid. It is shown that in general, the potential of Siberian spruce individuals associated with the biochemical level of the formation of adaptive reactions is highest in plants in the northern regions of the republic, i.e. in areas with more extreme growing conditions. Materials were obtained on the basis of which it is possible to develop a program for monitoring plantings and restoring forest stands.
