Entre Gaspar Serrano y Giovanni Battista Contini: la reforma barroca del campanario de la catedral de Zaragoza
Authors: Ibáñez Fernández Javier , Sutera Domenica
Published: December 2023

La colocación de la campana Valera, que había sido refundida en 1679, terminó obligando a reformar el campanario de la catedral de Zaragoza. Los proyectos preparados por diferentes maestros locales fueron presentados por el Cabildo a Francisco de Herrera, arquitecto de Carlos I1, que fue rechazándolos uno tras otro hasta que los canónigos decidieron enviar el realizado por Gaspar Serrano a la Academia de San Lucas de Roma, en donde fue sometido al juicio de Giovan Battista Contini, que acababa de ser nombrado "Principe" de dicha institución, y los "stimattori di architettura" en ese momento, Carlo Rainaldi y Carlo Fontana. Después de rechazarlo, elaboraron un nuevo proyecto -en realidad, una corrección siguiendo las claves del barroco-tardío clasicista- que se envió a Zaragoza, en donde recibió la aprobación general y fue puesto en ejecución prácticamente de inmediato.
En el Archi vo de la Seo de Zaragoza se conserva una ingente documentación relacionada con el proceso, y parte del corpus de diseños, desde el proyecto de Gaspar Serrano hasta las copias realizadas por Giovan Battista Contini, testimonios de un interesantísimo debate entre una arquitecuta considerada "local", pero abierta, en realidad, a modelos exógenos, solo que muy diferentes a los propugnados por la Academia, y el barroco-tardío clasicista de escuela romana que dicha instituticón colaboraría a difundir por todo el continente europeo.
La biblioteca del genovés Juan Luis de Musante (1587), maestro mayor de obras reales de Felipe II
Authors: Tarifa Castilla María Josefa
Published: December 2023

Juan Luis de Musante, genovés afincado en España desde la década de los 70 del siglo XVI, trabajó al servicio del monarca Felipe II en el último cuarto de la centuria en diversas construcciones regias como maestro mayor de obras reales de Navarra, quedando al frente de la dirección de la edificación de la ciudadela de Pamplona (c. 1575- 1587). Este arquitecto poseyó una de las más nutridas y voluminosas bibliotecas de su tiempo, en lo que se refiere a artistas que desarrollaron su actividad fuera del ámbito cortesano, como revela el presente estudio. La publicación del inventario de los 114 volúmenes impresos que conformaban su librería contribuye a un mayor conocimiento de la adquisición y uso por parte de los artífices en el Quinientos de la tratadística artística, junto a diversas materias afines a la construcción como las matemáticas, la geometría, la aritmética, la perspectiva o la fortificación, entre otras disciplinas históricas, filosóficas y científicas; en definitiva, cuáles eran las fuentes gráficas y literarias de nuestros artistas, los libros y tratados más leídos y manejados por los arquitectos del siglo XVI.
De las guerras con Francia, Italia y San Quintín (II)
Authors: Bustamante García Agustín
Published: December 2023

La guerra en el Norte entre Enrique II y Felipe II dio lugar a una gran producción de grabados y dibujos con marcado carácter propagandístico, donde tomaron parte muy activa también las prensas italianas. Felipe II consideró siempre decisivos aquellos acontecimientos, los cuales fueron grabados y pintados por el artista flamenco Anton Van den Wyngaerde, que estaba al servicio del Monarca Católico. Antonio Moro retratará al Monarca vestido como estuvo durante aquella guerra. Finalmente, Felipe II encargó a sus artistas italianos que representaran los hechos memorables de aquella guerra en el muro norte de la Sala de Batallas del Monasterio de San Lorenzo el Real del Escorial.
Una aproximación al estudio del taccuino de los Tornés: Diseños y textos de la Regola de Vignola en el arte del Alto Aragón
Authors: Juan García Natalia
Published: December 2023

Este trabajo estudia un libro de trazas de una familia de arquitectos originaria de Jaca (Huesca). Se trata de un manuscrito elaborado por algunos miembros de la saga Tornés que contiene interesantes alzados, secciones y plantas de edificios del Alto Aragón, así como numerosos diseños, apuntes, trazas, dibujos arquitectónicos y ejercicios de estilo. Los setenta y un folios de los que se compone este manuscrito permiten establecer una clara vinculación con la tratadística arquitectónica de su época, especialmente con el tratado de Giacomo Barozzi di Vignola titulado “La Regola delli cinque ordini d’architettura” publicado en 1562 del que estos arquitectos copiaron veinticuatro láminas en el taccuino que estudiamos.
El traslado de los reyes navarros a la catedral de Planplona (1865-1866).: Arte y artistas para una ceremonia frustrada
Authors: Azanza López José Javier
Published: December 2023

En 1865 y 1866, coincidiendo con el anuncio de sendas visitas de Isabel II a Pamplona, la Diputación Provincial de Navarra intentó el traslado a la catedral de los restos de los antiguos monarcas navarros, depositados durante siglos en el monasterio de San Salvador de Leyre, al que los avatares del siglo XIX habían conducido a un estado de ruina.
Con tal fin, organizó una función cívico-religiosa en la que el arte desempeñaba un papel de primer orden a la hora de crear el marco y ambiente propicios. La decoración escenográfica del espacio catedralicio, la construcción de una urna funeraria, y el levantamiento de un enlutado catafalco, constituyeron las principales manifestaciones artísticas proyectadas, para cuya ejecución las instituciones navarras se pusieron en contacto con renombrados artistas madrileños y catalanes, caso del ebanista Juan José Muñoz, de los escultores Venanci y Agapit Vallmitjana, y del pintor Antoni Caba i Casamitjana. Finalmente, la suspensión de las visitas regias, y la aprobación por parte de la Academia de San Fernando de las obras de restauración de Leyre, acabaron frustrando el plan.

The International Classification of Functioning is a tool that will provide a patient-centered, interdisciplinary approach to physical therapy for children requiring palliative care. Purpose: to analyze the dynamics of indicators for assessing impairments and limitations according to the components of the International Classification of Functioning in the process of rehabilitation of palliative pediatric patients of non-oncological profile. Material & Methods: empirical methods (comparison, description, measurement), theoretical methods (axiomatic), general logical methods (analysis, synthesis, generalization), multiple regression method. The basis of physical therapy for pediatric non-cancer palliative patients has been the biopsychosocial model presented in the International Classification of Functioning of Children and Youth (ICF-CY). Domains of ICF-CY components were selected that took into account the symptomatology of the criteria for palliative conditions. As a result, the list of domain codes in the study included 17 categories: structures and functions of the body – 6 categories (s710, b280, b710, b735, b760, b134), activity and participation – 7 categories (d310-340, d415, d465 d820, d920), environmental factors – 3 categories (e355, e320, e115). Initial patient surveys were interpreted into ICF classifiers and patient categories were generated. Results: the initial examination established the main limitations, revealed the severity of impairments in each domain, and recorded the vast majority of severe, absolute impairments in patients of both groups. A control rehabilitation assessment 24 months after the start of therapy showed positive dynamics of ICF indicators in both groups. Calculation of the dynamics of changes in classifiers showed that the components of the functioning of the body in the main group corresponded to 123,0%, in the comparison group – 52,9%, for components of activity and participation – 154,4% in the main group and comparison group – 49,9%; components Environmental factors – 81,6% in children of the main group and in patients of the comparison group, respectively – 22,9%. A reliable correlation has been established between all components of the ICF-CY version, mathematically confirmed, and the correlation coefficient is 0,787378. Conclusions: the use of the International Classification of Functioning contributed to a comprehensive examination of patients in need of non-oncological palliative care, helped to formulate a multi-vector rehabilitation program and ensured monitoring of the effectiveness of the rehabilitation program.

Published: December 2023

We have developed the apparatus-methodical complex of laboratory investigations of fractured reservoir rocks of hydrocarbons. Basing on the study of variability of acoustic properties in different-oriented directions for measuring of raw pieces of core, it was possible to develop the apparatus for the express-diagnostics of the inner structure of the rock. The results of analysis of anisotropy of acoustic properties of the core give us the possibility to choose the specimens with abnormal properties on which one can conduct further investigations for determination of the factors of heterogeneity of rocks. Measuring of the velocity of longitudinal and transverse oscillations with recording their wave pictures is conducting in the acoustic bath. The acoustic system is equipped with corresponding adapter for connection to the computer that enables us to keep up the recording of all parameters of measuring. To estimate the permeability of microfractures and the influence of composite taut state upon them we have developed the device for studying radial filtration the results of which allow us to estimate the rock permeability due to the change in the structure and microfractures size depending upon the value and the character of the taut state. To measure deformational-strength parameters the corresponding plant was developed and produced, which was additionally equipped with a meter for the measuring of deformation, that allows to measure the values of contact strength, elasticity module and the boundary of rock strength while one-axis charging. The parameters are determined at arbitrary points of the core cuts, and the velocity of charging is half-automatically regulated at a wide bounds. The device is equipped with the electron controller that allows us not only to measure the value of contact strength, but to conduct observations on a display as to the changes in deformation depending on the charging value in real time and to put down the parameters of investigations into corresponding data base. Obtained characteristic of rocks is not only parametric basis for interpretation of materials of charging, but for the estimation of the changes in volume, type of porous space and permeability, and also for modelling of formation conditions of fractured reservoir, and on the whole, for prediction of zones (plots) where a dense rock with corresponding mechanical parameters should acquire the properties of the collector. The usage of the complex for the studying of fracturing in oil geology allows us to widen the prognosis and discovery of new fields and to improve production and exploitation possibilities of already acting ones.

One of the primary mechanisms of retinal neurodegeneration in diabetes mellitus is gamma-aminobutyric acid (GABA) deficiency that makes the use of GABA-benzodiazepine receptor modulators a promising option for the correction of this diabetic complication. The aim of this study was to determine the effect of the benzodiazepine receptor agonist carbacetam on the expression of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor-1α (HIF-1α) in retina of rats with hyperglycemia. Experimental diabetes was modeled by a single administration of streptozotocin (50 mg/kg) to three-month-old male Wistar rats. Immunoblotting and immunohistochemical studies were performed using monoclonal antibodies against VEGF and HIF-1α. It was shown that the development of diabetic retinopathy (DR) at the early stages was accompanied by a progressive multifold increase in the retina content of VEGF on 7-28 days and HIF-1α on 28th day. Insulin and insulin+carbacetam treatment significantly alleviated diabetes-induced overexpression of both HIF-1α and VEGF. Carbacetam was shown to block the diabetogenic increase in VEGF content in retina. The introduction of insulin with carbacetam significantly reduced the expression of VEGF and the development of specific morphological manifestations of DR. Thus, restoration of GABA-ergic signaling can be used as a promising therapeutic option for the correction of DR disorders.

Studies targeting small molecule metabolites (amino acids, sugars, nucleotides, lipids) in connections with gut microbiota metabolites that impact the host metabolome give a possibility to define a special metabolic signature of different diseases. Plasma amino acids (AA) profile is known to be a new promising biomarker for the screening of coronary artery disease (CAD) pathogenesis connected with gut dysbiosis. The aim of our study was to estimate the spectrum of plasma amino acids in CAD patients with atrial fibrillation (AF) and to check their connections with the gut microbiota metabolites. 300 patients were divided into three groups: CAD – 149 patients with CAD but without arrhythmias, CAD+AF – 123 patients with CAD and AF paroxysm and control group– 28 patients without CAD and arrhythmias. Plasma AA level was detected by ion exchange liquid column chromatography. Significant changes in the content of plasma Glutamate, Glutamine, Glycine, Alanine, Valine and Tyrosine and combinations Isoleucine+Leucine/Valine, Glycine+Serine, Glycine/Methionine, Phenylalanine/Tyrosine, Glutamine/Glutamate in CAD+AF patients were detected. A strong reliable connection between plasma AA spectrum and gut microbiota metabolites trimethylamine, trimethylamine-N-oxide and total amount of fecal short chain fatty acids was determined. The highly validated plasma AA combinations Isoleucine – Glycine (area under ROC-curve 0.8122) and Phenylalanine – Glycine (area under ROC-curve 0.8061) that can be used as the early markers of AF paroxysm in CAD patients were proposed.

The aim of the work was to determine the cytotoxic activity of marine actinobacteria exometabolites on the human larynx adenocarcinoma Hep-2 and rhabdomyosarcoma RD cell lines. Exometabolites of 6 strains of Streptomyces sp. were extracted with ethyl acetate and their composition was determined with UltiMate™ 3000 BioRS UPLC System coupled to mass spectrometer. Cytotoxic activity of exometabolites against cancer cells was determined after 24 hours of incubation by microscopic examination of cell morphological changes and the degree of cell monolayer degeneration. Exometabolites from Streptomyces sp. Myt7b strain showed the highest cytotoxic activity and at concentration of 500.0 μg/ml caused up to 90.0% death of RD and Hep-2 cells. The presence of 53 identified compounds with potential cytotoxic activity, including enterocin, 6-prenyltryptophol, medelamine A and turbinaric acid was detected in Streptomyces sp. Myt7b exometabolome. It is concluded that this strain is a promising producer of compounds with anticancer activity.

The importance of eddy current measurements of specific electrical conductivity (SEC) of materials in non-destructive testing for solving problems of structuroscopy is discussed. In particular, their significant role is shown for estimation of the degree of changes in the mechanical characteristics of structural materials due to degradation processes in their structure. The influence of the temperature of metallic structural materials on the results of eddy current measuring of SEC has been studied. An analytical expression for the output signal of the SEC measuring channel of an electrical eddy current conductivity meter for real temperature of material is obtained. It depends on the value of the material SEC at a nominal temperature value (usually 20 C), temperature coefficient of electrical resistance of the material and the deviation of the material real temperature from the nominal value. It is shown that in order to tune out this effect and bring the measurement results to the nominal temperature, it is necessary to use eddy current meters with an additional channel for measuring the material temperature in the testing zone. The output signal of this channel is used to correct the SEC measurement results. This is carried out by multiplying the output signal of the SEC measurement channel and some auxiliary signal. This auxiliary signal is generated from the output signal of the temperature measurement channel by it scaling and summation with the signal of the direct current voltage reference source. A functional diagram of the eddy current SEC meter with temperature correction is proposed. A detailed description of it operation is given. In the absence of preliminary information about the grade of material and the value of its temperature coefficient of electrical resistance, is proposed to suppress the influence of temperature by test changes in the temperature of the material in the testing zone. At the same time, it is necessary to adjust the gain of the scale converter. This is done until the readings of the eddy current SEC meter do not depend on the material temperature in the testing zone.

The diffraction of the plane elastic SH-wave from a semi-infinite interface crack on junction of two elastic semi-infinite media is studied. The crack is modelled by the mathematical cut with no stress on its faces. The displacement and the stress fields are continuous outside of the crack. The wave diffraction problem is reduced to the solution of the mixed boundary value problem for Helmholtz equation. We search the solution which satisfies the Neumann boundary condition on the crack faces and the continuity condition for the stress and displacement fields outside of the crack. The radiation condition at the infinity and the Meixners condition at the crack tip must be also satisfied. Using the Fourier integral transform, the mixed boundary value problem is reduced to the Wiener-Hopf functional equation which is valid in the given strip of regularity in the complex plane. The method of factorization and decomposition, as well as the Liouvilles theorem, are used to solve this equation. Its kernel function is factorized and represented as a product of two split functions that are regular in the overlapping half-planes. These ones allow for the simple poles outside of the regularity regions. The solution of the Wiener-Hopf equation is presented in analytical form. The scattered displacement field is found for an arbitrary frequency and sounding angle by applying an inverse Fourier integral transform to the solution. The asympŹtotic formula for the stress intensity factor (SIF) at the crack tip is obtained. The correlation between complex amplitude of the SH-wave far scattered displacement field and the SIF caused by this field is obtained for an arbitrary radiation angle, frequency and medium parameters. This allows us to express the SIF through the amplitude of the far field if the radiation frequency, sounding angle as well as the physical characteristics of materials are known. It is shown that in the plane that is normal to the tip of the crack the ratio of SIF for the given junction and two fixed values of the sounding angle or two sounding frequencies is proportional to the ratio of the scattered fields. It is found that under above mentioned condition the proportionality rate does not depend on material properties. The obtained relations can be applied for estimation of the SIF with changing frequency and sounding angle.

Introducción: La Rata de Magdalena, Xenomys nelsoni, es un roedor endémico de México, de distribución restringida a las selvas bajas caducifolias densas, en una pequeña región de la costa del Pacífico mexicano. Es una especie poco conocida, catalogada como "En Peligro" de acuerdo con la Unión Internacional para la Conservación de la Naturaleza (IUCN). Este desconocimiento unido a la alta tasa de deforestación de su hábitat hace que su conservación sea prioritaria. Objetivo: Realizar un recuento histórico de los registros depositados en las colecciones científicas, generar mapas de distribución potencial y analizar el estado de conservación de la especie. Método: Los datos de ocurrencia de las especies se obtuvieron de la literatura y bases de datos digitales y se analizaron por décadas. Se utilizaron los programas GARP y MaxEnt para generar los modelos de nicho ecológico. La importancia de las variables en el modelo se estimó mediante un análisis Jackknife. Resultados: A lo largo de 129 años 19 recolectores registraron 69 ejemplares, de los cuales 65 están depositados en siete colecciones internacionales y una nacional. Aunque la especie sólo se ha recolectado en Jalisco y Colima, la distribución potencial de X. nelsoni incluye también el estado de Michoacán. De esta área estimada, sólo el 1.5 % se encuentra dentro de un Área Natural Protegida. Conclusiones: Los resultados de la distribución potencial podrían ser utilizados para verificar la presencia de la especie en lugares donde no ha sido recolectada como el norte de la Reserva de la Biosfera Chamela-Cuixmala y en algunas zonas de la provincia fisiográfica Costas del Sur en el estado de Michoacán. Es necesario incrementar los muestreos en regiones poco estudiadas predichas por el modelo y aumentar el área de protección.

Published: December 2023

Introducción: La fisiología vegetal tiene un impacto mundial en términos de publicaciones dada la significancia de sus investigaciones en el desempeño de las plantas, ya sea en sus mecanismos, eficiencia, adaptabilidad, genética y evolución. Al mismo tiempo, la Revista de Biología Tropical (RBT) es una de las más importantes revistas científicas originarias dela región neotropical, y este año llega a sus setenta años de creación y publicación continúa.

Objetivo: Identificar los temas, procedencia, equidad de género e impacto de las publicaciones en RBT en el área de fisiología vegetal.

Métodos: Se selecionaron todos los artículos de la RBT desde Web of Science entre 2020—2022. De este grupo de artículos, uno a uno se escogieron los artículos con alguna relación con la fisiología vegetal (n= 170). Posteriormente, se determinó el número total de citas y el número de artículos por país de afiliación del autor. Calculamos el índice de equidad de sexo por artículo como el número de autoras entre el total de autores.

Finalmente, se graficaron las frecuencias y se aplicaron análisis de χ2.

Resultados: La fitoquímica predominó con el 25.3% de los artículos, seguido por germinación—semillas (20 %), cultivo de tejidos—embriogénesis somática—biotecnología (17.6 %) y fisiología del estrés (10.6%). El tópico de la fenología destacó con la mayor cantidad de citas por artículo (10.33), seguido por fitoquímica (8.98), patología vegetal y fisiología del estrés (8.57 y 8.56, respectivamente). La mayor parte de las publicaciones provienen de Costa Rica, seguidas por Colombia y México. Finalmente, solo el 38.6 % de las mujeres participan en publicaciones de fisiología vegetal.

Conclusiones: Pese al bajo número de publicaciones sobre fisiología vegetal en los últimos 22 años, la RBT sigue la tendencia internacional sobre los tópicos actualmente investigados y representa un recurso importante para la difusión en estos temas de los países neotropicales. Finalmente, las publicaciones en fisiología vegetal del siglo XXI continúan con una menor representación femenina.
Prevalence, distribution and epidemiological risk factors of foot-and-mouth disease among the cattle population of Bangladesh: A meta-analysis
Authors: Hasan M. , Mia M. M.
Published: December 2023

Foot-and-mouth disease (FMD) is a devastating viral infection of cloven-hoofed animals. The disease turned into an endemic in Bangladesh causing prodigious impairment to the nation’s economy and livestock population. For further usage, developing a detailed summary of the disease condition in Bangladesh is imperative. Hence, this study identified the prevalence of FMD among cattle populations accompanying by potential risk factors and climatic variables. Using the Jamvoi 1.2.27 software, the authors analysed 30 studies for estimating the random model effect function. Based on the meta-analysis, the overall pooled prevalence of FMD was 25% (95% confidence interval [CI]: 15-35%). The research professed a significant difference between the prevalence rate of males (33%, CI: 22-45%) and females (26%, CI: 14-39%). Moreover, the study reported a noteworthy line of the tendency for the increasing rate of prevalence in adult and old animals than in young individuals. Furthermore, the results showed high prevalence rates in dry season compared to wet season. Thus, this study will permit the government to implement an immediate control program. Moreover, each data gathered will help the prevention of FMD.

Authors: Šimáková Jana , Pražák Tomáš
Published: December 2023

This paper aims to evaluate the influence of investment and R&D expenditures on the performance of large companies that are headquartered in the Europe using regression analysis of the generalized method of moments. The independent control variables are GDP per capita and the interest rate represented by the yield of 10-year state bonds. The sample period is 2010–2018. Our result shows that the growth of R&D expenditures and investments negatively affected the profitability ratios of the firms in the year of implementation. While concentrating on the macroeconomic control variables, the results support an assumption about the positive effects of GDP on the majority of the net income, ROA and ROE estimates. On the other hand, negative effects of interest rates were found.
The mythmaking of children heroes during the communist regime in Bulgaria – the case of “the heroes of Belitsa”
Authors:   South-West University “Neofit Rilski”, Blagoevgrad, Bulgaria, Angelova Milena
Published: December 2023

The paper presents the constructing of the image of “child heroes” in the memory policies imposed by the communist regime in Bulgaria after 1944. The Bulgarian case of establishing patterns of child heroism during the communist regime followed the Soviet examples of policy on the youngsters. In pursuing its own ideological goals, after 1944 the political regime in Bulgaria imposed new content of child education and turned children into an instrument and object of the propaganda of new heroism. The biographies of the “child heroes” were turned into examples of education and identification for the young generations. Despite the fact that several local cases existed, the cases of Mitko Palauzov, the “six children form Yastrebino” and the “heroes of Belitsa” – Vasil and Sava Kokareshkovi were presented as the national heroic patterns for the youngsters. The specific case of Vasil and Sava Kokareshkovi has been followed in the paper.
A Pact with the Third Sector. Between Co-Production and Civic Participation. The Italian Case
Authors:   University of Bologna (Italy), Bassi Andrea
Published: December 2023

The co-creation/co-production paradigm received significant attention in the last decades from Public Administration managers, officials, and scholars as a viable tool to overcome the limits of the New Public Management framework. Some scholars recognise that co-creation can be the basis for building an alternative administration model called New Public Governance. Other research found that co-creation is an innovative practice in the social investment policy frame. A more recent EU research project examines the idea and practice of co-creation in public services informed by lived experience pilots in 10 European countries. This paper presents the Italian case as an example of an institutional configuration open to the citizens’ participation in the co-design of public services. The paper is organised as follows. In the first paragraph, we illustrate the recent development of the legislation concerning the participation of citizens and civil society organisations in designing and delivering public services and/or management of common goods. The second paragraph deals with a deep analysis of “grey material” and scientific publications concerning the history, evolution and future perspectives of the “Shared Administration” procedures. The third paragraph presents a case study of collaboration between citizens, Third Sector/Civil Society Organisations (TSO/CSO) and public administration at the local level (Municipality of Bologna). The conclusive paragraph summarises the key findings of our study.

The description of a new method for increasing the resolution of radio pulse sensors (RPS) designed for short- range radar systems (SRRS) for detecting and measuring motion parameters of location objects is presented. The essence of the method is that the controlled area of space with the targets located in it is periodically irradiated with probing radio pulses, and during their radiation, radio pulses reflected from the targets are simultaneously received and divided into two quadrature channels. Next, they are mixed with probing radio pulses, and the time-overlapping parts of these radio pulses are converted into the region of low Doppler frequencies in the form of two quadrature video pulses. Then, the quadrature video pulses received in these channels are sampled by amplitude, stored at multiple points in time and digitally processed according to the proposed algorithm. The method is implemented in the RPS made on the basis of a horn-lens antenna, a Doppler receiving and transmitting module with quadrature outputs of converted signals, a synchronization and pulse generation unit, as well as a digital signal processing unit. The RPS can be used in onboard (for example, automotive) SRRS designed to detect moving targets, measure the distance to them, as well as determine the speed and direction of movement.

Currently, to collect data on the state of the resources of the agro-industrial complex, groups of unmanned aerial vehicles are widely used, interaction with which is carried out by creating wireless ad-hoc flying networks, communication with which from ground control complexes is provided either using space telecommunication systems of satellites, and by means of one or more nodes of such a network. The continuous tightening of requirements for the technical characteristics and parameters of modern wireless telecommunication systems (especially for increasing the speed of information exchange and communication reliability) force developers to look for new approaches in designing radio transmitting equipment. In particular, it is known that the signal-to-noise ratio is significantly affected by the spectral purity of the signals synthesized using special multi-c hannel radio transmitter signal conditioners. It is shown that in order to improve the spectral characteristics of such shapers, it is possible to use the method of automatic compensation of the noise band of the frequency region in which the most undesirable discrete spectral components are presented Based on the proposed approach, the structural and functional diagram of the carrier waveformer with improved spectral characteristics has been developed, for which the main mathematical relationships (differential equations, transfer functions, noise models) have been obtained, on the basis of which the corresponding simulation has been accomplished, confirming the effectiveness of using the auto-compensation principle.

The study is focused on estimating the fiscal implications of conversion to taxation of corporate property on the basis of cadastral value. The relevance of the work is determined by the importance of forming a stable tax base for property tax in the context of the conversion to taxation based on the cadastral value of the corporate property tax. The purpose of the study is to estimate the implications of a complete conversion to the use of cadastral value as the only source of formation of the tax base for corporate property tax. The study aggregates information from the state dataset «Data on cadastral value of real estate properties by territorial affiliation» of Rosreestr (The Federal Service for State Registration, Cadastre and Cartography). The research procedure consists in the fact that, based on the processing of this information, the total cadastral value and the number of capital construction properties in the regions of the Russian Federation are characterized. At the same time, the hypothesis of the research is that a complete conversion to taxation of corporate property on the basis of cadastral value results in the growth of tax revenue from corporate property tax. The characteristics of the monetary and numerical parameters of such a potential tax base are given and the implications of a complete conversion to the taxation of corporate property on the basis of cadastral value are estimated. The resulting estimate is compared with actual revenues, and a conclusion is made about the positive effect of a full conversion to the use of cadastral value as the tax base for corporate property tax. The theoretical relevance consists in the fact that the possibility of the direct use of data of the state dataset for formation of information on the tax base on corporate property tax is critically analyzed. The practical relevance is determined by the calculation of the potential growth of corporate property tax revenues in connection with the full conversion to the calculation of the tax base only on the basis of cadastral value as per the Rosreestr dataset.

The study is devoted to the problem of the spatial differentiation of population income in Russia's regions. The objective of the study is the development of a system-dynamic model for the calculation of spatial differentiation trajectories of income parameters due to various scenarios. Regional features of the human capital development level influencing the spatial differentiation of population income in the Russian regions are assumed. The formulation of the mathematical problem is based on the results of regression analysis of the influence of time series values of socio-demographic factors on population incomes differentiation (Gini coefficient). A specialist application, PowerSim Studio Express 10, was used for model design. Rosstat data on households in the Russian regions were used for calculation of the model experimental trajectories. The main research methods are the following: dynamic analysis of time series; econometric and system-dynamic modeling. As a result of the study, a system-dynamics experimental model was proposed. It was tested in application to eight regions with the most reliable statistical relationship between socio-demographic factors and the Gini index. Numerical experiments were used to simulate real economic processes of convergence and divergence in order to identify the main trends and features of territorial income differentiation depending on local priorities of vocational education development. It was shown that an increase in the level of education, both higher professional and secondary vocational, mainly leads to increased income differentiation. The theoretical significance of the results obtained lies in the deepening of the understanding of the regional features of human capital development influencing the spatial differentiation of population income. The practical significance of the study lies in the expansion of instrumental support for decision-making in the implementation of state policy in the field of regulating the population incomes differentiation at the regional level.
Modeling of the Nexus Between Environmental Regulations of Trade Partners and Export Volumes: Analysis of Russian Regions

Published: December 2023

Export development is one of the priorities of the Russian economy. Exporters and companies planning to enter the international market face a number of limiting factors. Transitional climate risks, mainly represented by trading partner countries' environmental regulation aimed at internalizing national and global negative environmental externalities, are also among these factors. However, the global climate agenda can not only have a negative impact on export performance, but also generate growth opportunities. The purpose of this study is the econometric modeling of the impact of environmental regulation of trading partner countries on the dynamics of export volumes of Russia's regions based on data for the period of 2013-2020. In addition, the study is aimed at identifying regional factors that determine the sign of the influence of climate regulation of importing countries on export volumes. The study assumes that the effect of climate regulation on export performance is different for the regions of Russia and is determined by institutional and environmental characteristics. The estimation of the gravity equation using the Poisson pseudo-maximum likelihood method for different subsamples of Russia's regions demonstrated that the stringency of environmental regulation of the partner countries is negatively related to the volumes of Russian exports, but there is a positive correlation in the case of regions characterized by favorable conditions for innovation activity and active environmental policy. It was also detected that the regional budget spending on environmental protection do not provide a stimulating effect of climate regulations. Thus, in order to minimize the negative impact of transitional climate risks, special attention of the state should be paid to creating an environment conducive to innovation and the formation of the most effective environmental policy at the regional and national levels. The theoretical significance of the study lies in expanding the traditional gravity model by including the environmental determinants of trade, while the practical significance of the work is represented by recommendations to regional authorities on minimizing the negative impact of transitional climate risks.

The relevance of the study is due to the fact that in recent decades a socio-economic development of the territories of states and regions has been significantly affected by global climate change. Due to changes in temperature, precipitation, solar radiation, etc. fires are occurring; individual ecosystems are being transformed, which in turn negatively affects the quality of life of the population as well as the development of industries and economic systems. All of the above, on the one hand, emphasizes the relevance of developing tools and models for assessing the consequences of such an impact, and, on the other hand, highlights the need to develop a special adaptive mechanism for managing the socio-ecological and economic system, taking into account the impact of climate change. Accordingly, the aim of the work was to develop a model for the implementation of scenarios and forecasting the consequences of global climate change for regional socio-ecological and economic systems. To achieve this goal, the authors put forward a hypothesis about the possibility of developing and constructing an instrumental numerical model that allows, based on long-term statistical data, for modeling scenarios of adaptation of multi-level (both global and regional) socio-ecological and economic systems to the consequences of global climate change. To achieve this goal, a set of general scientific and economic-mathematical methods was used, mutually complementing each other, including methods of abstract-logical analysis, principal component analysis (PCA), methods of system dynamics, etc. The authors obtained the following results: firstly, an analytical model of adaptive development of the regional socio-ecological-economic system was developed; secondly, a list of basic prerequisites that have a fundamental impact on this system due to climate change was substantiated; thirdly, a forecast model was proposed of a stable trajectory of the development of a regional socio-ecological-economic system under the conditions of global climate change. The scientific significance of the study is to expand scientific knowledge about approaches to modeling scenarios for adaptation of socio-ecological-economic systems to global climate change. The practical significance of the work consists in the possibility of using the results for the development and improvement of plans for the adaptation of Russia's regions to climate change, including in the areas of environmental management and economic activity, civil defense, protection of the population and territories from natural and man-made emergencies.
