FIRST INVESTIGATIONS OF DAMAGE TO BUILDINGS AND STRUCTURES AS A CONSEQUENCE OF COMBAT ACTIONS
Authors: NUZHNY Valery 
Published: December 2022

On February 24, 2022, a large-scale invasion of the troops of the Russian Federation on the territory of Ukraine took place. In particular, active hostilities took place on the territory of Kyiv region within the boundaries of the settlements and surrounding them Borodyanka, Makariv, Gostomel, Irpin, Bucha, Vorzel, etc.
The result was the destruction and damage of a large number of buildings and structures, which suffered shock-explosive and fire damage, not typical for operation in peacetime conditions. It is also necessary to distinguish between direct damage to structures from the impact of ammunition (missiles, shells, mortar mines, large-caliber bullets, etc.) and secondary damage from the action of an explosive air wave. Destruction in places has a large-scale and systemic nature, when, for example, as a result of fire and temperature deformations during heating, cracks develop on the walls in other areas.
There are also hidden defects, when, for example, internal delamination of brickwork occurs due to impacts. Since state institutions and units of the State Emergency Service did not work in populated areas that were under occupation, the fires did not go out and this led to the deepening of their consequences. For the first time after the de-occupation of the northern regions of Ukraine, the problem of restoring buildings and structures of both critical infrastructure and housing arose, and this problem is relevant during the subsequent liberation of other regions of Ukraine from occupation.
From April until now, works on conducting surveys of buildings and structures in accordance with the accepted methods and regulations of the Ministry of Regional Building of Ukraine have been ongoing. Although in fact each case is unique, certain regularities can be found in determining the nature of damage and their classification for the purpose of choosing methods of strengthening and repairing structures.
In many ways, the quality of the assessment depends on the experience of the expert and the design engineer performing the survey. Thus, in the first months, when surveys were conducted by leading organizations, including state research institutes, conclusions were given about the partial dismantling of buildings and structures, which, when alternative surveys were conducted, turned out to be hasty and erroneous.

Published: December 2022

The main processes necessary for the development of microstructure and hydration of concrete and their composites for use in structures with high durability, frost resistance, water resistance are analyzed. The potential development that will ensure the strength of concrete and their composites, which have been modified by a complex of fine additives in the time range up to 365 days, has been determined. The experimental formulation of the concrete mixture, which was modified by a complex of fine modifiers based on microsilica (MK) and metakaolin (MTK), was used for testing. Concrete mixing technology has also been improved. The structure of ultra-high-strength concrete is formed during physicochemical reactions, which are accompanied by the binding of free water with clinker minerals, the formation of a saturated solution of crystal hydrates and their subsequent crystallization. Determining compounds of cement structure are such hydration products as: calcium silicate hydrate with various modifications, portland, calcite. For a more complete picture of the formation of hydration phases in high-strength concrete composites and the effect of ultrafine modifiers, the microstructure of fracture surfaces and their phase composition on the 28-day aging of concrete composites were studied by scanning electron microscopy and energy-dispersive X-wave spectroscopy.
Comparative microanalysis and elemental analysis of various concrete composites of high structural strength and density using the methods of X-ray diffraction and energy-dispersive X-wave spectroscopy. However, the presence of Al in the later stages of hydration can also lead to the formation of secondary phases. The molar ratio of CaO to SiO2 in C-S-H is one of the main parameters for determining and controlling the properties of the calcium hydrosilicate system, which can be used to characterize some parameters of concrete durability. The structure of concrete is actually the main factor that determines its mechanical properties and their security throughout the life of the structure. Regularities of formation of structure and properties are common to all types of concrete.

Published: December 2022

Providing all parameters according to two groups of limit states at the design stage is a multi–criteria task. Optimal design helps to perform such tasks. When the phenomenon of resonance occurs, it is necessary to change the frequency of forced oscillations of the load–bearing structures of various tanks and coatings in order to ensure sufficient strength and stability of the structure and the building in general. For this purpose, there is a separate type of problem in optimal design that allows us to change the forced frequencies of oscillations using the example of the shell of the minimum surface on a rectangular contour.
In mathematical point of view, optimal design tasks are optimization tasks, finding the extremum of the target function (maximum or minimum). Methods of solving optimal design problems can be conditionally divided into two groups. One of them will include methods that are based on using necessary conditions for the extremum of the objective function. The second group includes methods: linear, convex and dynamic programming, random search methods. The application of modern methods of mathematical optimization requires powerful PCs with a large RAM, therefore, when choosing optimization, it is necessary to take into account the capabilities of computer equipment.
The optimization algorithm for single–criteria parametric optimization is performed as follows: the objective function is the weight of the shell of the minimum surface on a rectangular contour, the design variables are the shell thickness from 1 to 50 mm, the constraints are presented with first forced oscillation frequency is 0,15 Hz.
Using software complex Femap with Nastran and our own software, a single–criterion parametric optimization was made. The results of changing the objective function are reducing the weight of the shell by 2300 kg of C240 steel, which is equivalent to 10,3% without losing the strength and stability of the minimum surface shell on a rectangular contour. Using author's methodology and own software, it is possible to perform an effective optimization calculation for the minimum surface shell on a rectangular contour.

Published: December 2022

The article researched and established that in order to improve the tools, models and methods of organizational-technological and geo-informational modeling of complex organizational training, the branch specifics of objects were taken into account, since cluster construction represents a variety of objects, and is also characterized by significant uncertainty of information support . At the same time, a significant amount of geoinformation, which is necessary for high-quality organizational and technological preparation of the territories allocated for construction, is not used. The work analyzes the main tasks and stages of complex organizational preparation of concentrated construction, existing technologies of automation of construction processes, to identify the technology of geoinformation modeling taking into account the specifics of the industry and the necessary tools for assessing the adequacy of the necessary information support.
The article describes the practical implementation of a geoinformation modeling tool for complex organizational preparation of concentrated construction for the development of a digital geoinformation 3D model of a consolidated plan of engineering networks based on the modern GEOCAD software complex of the GEOKAD company - a domestic developer of engineering GIS, which works in the AutoCAD 3D modeling environment. The researched experimental approbation of the methodology for assessing the reliability of the organizational preparation of the territorial cluster was carried out on the example of the development of the territorial cluster in the city of Vinnytsia, taking into account the possible states of the system and with the calculation of reliability indicators of consolidated calendar plans for the preparation of construction sites for the cluster objects. An analysis of the geoinformation provision of all cycles of organizational training was carried out and showed that in real practice there is no single system and comprehensive approach to both the formation of information provision and the functioning of the services of the customer-builder. In this connection, models of the functioning of the complex training system were considered and improved.

Communicative semantics in Lviv pop-jazz continuum: «Picardian third» and «Orpheus»
Authors: Kulyniak Mykhailo 
Published: December 2022

The purpose of the work is to identify the specifics of the communicative semantics in the Lviv pop-jazz continuum on the example of the vocal octets «Picardian Third» and «Orpheus». The research methodology is based on the use of cultural and analytical methods, on the basis of the theoretical understanding of the communicative semantics concept and the extrapolation of the specified phenomenon to understanding the analysis of the specified creative collectives’ activities. The scientific novelty of the research: the article proposes a definition of the communicative semantics concept, which is interpreted as a set of meanings produced by one or another artistic centre in its multiple creative acts; the essence of the indicated semantics in the Lviv pop-jazz continuum is determined using the example of the octets «Picardian third» and «Orpheus». Conclusions. The specificity of the communicative semantics of creative collectives, whose activities are analysed in the article, demonstrates stylistic multiculturalism, while its nature is different in the two indicated octets. The semantics of the vocal formation «Picardian Third» from the point of view of pop-jazz communication is defined as a syncretism of national (folk, spiritual, and pop) and international jazz messages, when the essentially national repertoire is presented in jazz design. Instead, in the work of the «Orpheus» octet, we observe greater differentiation of the indicated messages; the communicative semantics of the collective is created in the process of simultaneous combination of various styles and approaches. At the same time, we can state that the activities of both octets harmoniously combine the tendencies of acculturation and inculturation, and this is a guarantee of the further harmonious development of multiple cultural processes associated with the specified collectives in the Lviv continuum and the European space, and also determines the prospects of future research into Lviv pop and jazz sphere.
Key words: communicative semantics, acculturation, inculturation, Lviv pop-jazz continuum, «Picardian third», «Orpheus».

Published: December 2022

The purpose of the article. The paper is devoted to the influence of the Greek-Byzantine spiritual heritage on the Ukrainian cultural and educational environment. The methodology of the study uses the historical-chronological method to reproduce the sequence of development of the sacred monody in European culture, primarily in Ukraine. The method of analysis and comparison has been used to identify common and distinctive international features of the development of sacred monody. The method of material synthesis helped summarise all the important conditions for the development of Ukrainian monophonic singing. The scientific novelty of the work is that it consistently examines the influence Byzantine monody on Ukrainian liturgical practice. The study is based on the practice of colophonic style of the Byzantine sacred monody. Conclusions. The aesthetic canons of the Greek-Byzantine spiritual culture were fully adapted with the Christian rite and reflected in the sacred monody. In the future, this determined the implementation of important church and educational reforms in the 16th century and the development of all layers of Ukrainian culture. At the same time, educational centres were developed, and printing houses at brotherly schools provided schoolchildren with the necessary textbooks. And what is important, all children without exception already at the initial stage of education got to know and studied the first notated collections of sacred monody, spreading the ancient traditions of singing in all social strata of society.

Scientific novelty. A conceptual understanding of the author's definitions of the concept of «choreographic culture» presented in the scientific works of leading foreign researchers has been carried out; essential features of the concept of «dance», starting from antiquity to the 17th century; its transformation has been analysed in the context of the development of folk choreographic culture of Ukraine in the 20th-early 21st centuries. Conclusions. The analysis of research on the problems of choreographic culture proves that it is characterised as a complex concept with the inclusion of scientific records of dances, creative personalities (directors, artists, teachers, art critics, musicologists, and theatre critics) inherent in the art of choreography. The study has revealed that in the scientific dimension of the XX–XXI centuries. most of the works are devoted to the stages of the formation and development of Ukrainian choreographic culture, its role in the preservation of national cultural values, the generalisation of the creative heritage of outstanding ballet masters, the regional specificity of Ukrainian folk dance, and an attempt to introduce the concept of «choreographic culture» into the scientific discourse. It can be noted that the development of choreographic culture invariably involves constant updating of theoretical analysis and the establishment of new aspects of understanding its specificity at the request of modern cultural processes.

Direct Calculation of Band-Pass Filters
Authors: Chervinskiy E. N. 
Published: December 2022

Introduction. When calculating band-pass filters (BPF), the circuit elements can be determined by converting the parameters of prototype low-pass filters (LPF). In a number of cases, the synthesized BPF does not have a direct prototype in the low-frequency range. Such filters include, e.g., BPFs with nodes tied to zero potential and other types of filters. Filters can be calculated directly by equating the coefficients of the synthesized filter transfer function (TF) and the realized TF obtained from the low-pass filter TF by the frequency conversion followed by solving the corresponding system of equations.Aim. To develop a methodology for direct calculation of band-pass filters with attenuation poles.Materials and methods. The simplest scheme of BPF with attenuation poles can be formed by two sequentially connected Г-shaped half-links on parallel circuits. Such a filter is realized only at certain requirements upon attenuation characteristics. When switching to BPF schemes with an additional parallel circuit in the transverse branch and a sequential circuit in the longitudinal branch, these restrictions are removed. In this paper, we develop a method for calculating inverse and quasi-elliptical BPF of П-shaped and T-shaped type, which have no restrictions when selecting the minimum attenuation and unevenness of the amplitude-frequency response (AFR).Results. The TF analytical expressions of the 6th and 10th order BPF were derived. Relations were obtained that allow the number of equations of the system for determining the filter parameters to be reduced. For П- and T-shaped 6th order BPFs, representations of circuit inductances through the central frequency and filter capacitances were obtained. This made it possible to express transfer functions through capacitances, at the same time as reducing the number of equations of the system. Examples of direct calculation of the 6th and 10th order PPFs were given.Conclusion. When converting TF of LPF, the frequencies of the realized AFR at both sides of the central BPF frequency are connected by certain relations. This fact makes it possible to eliminate the equations of the system that equate the coefficients of transfer function numerators, thereby reducing the total number of equations. Parameters, whose number exceeds that of the equations of the system, are selected arbitrarily from a number of standardized values. As a result, the accuracy of reproducing the realized frequency response is significantly improved.
Modelling Rainfall-Runoff Process of Kabul River Basin in Afghanistan Using ArcSWAT Model
Authors: Tani Hamidullah , Tayfur Gokmen 
Published: December 2022

Kabul River Basin is the most populated and an important source of water resources in Afghanistan. The Soil and Water Assessment Tool (SWAT) model, together with the ArcGIS and SWAT-CUP, is employed to predict the runoff in the basin. Nine years of meteorological and hydrological data are employed in the study. The DEM, the soil cover, and the land use/cover data are downloaded from the available global database. The ArcGIS based soil classification, the land use/cover, the elevation, the drainage, and the slope distribution maps of the basin are generated. The meteorological data from 18 different stations and the hydrological data from 7 different stations are obtained from the Ministry of Energy and Water of Afghanistan. The basin is divided into 48 sub-basins with a total number of 770 hydrological response units (HRUs). The sensitivity analysis results revealed that the flow characteristics of KRB are highly influenced by the groundwater and snowmelt. The model is calibrated using the data from 2010 to 2014 and validated employing the data from 2015 to 2017 at seven different hydrological stations. The SWAT-CUP is successfully used to calibrate the model for predicting monthly and daily runoffs. The calibrations and validations for the seven stations are achieved, on the average, with the correlation coefficient (R) of 0.78 (for daily flows) and 0.82 (for monthly flows), respectively. Total water yield in the basin is estimated to be 432.9 mm/year, corresponding to 31 176 Mm3/year, hardly meeting the demand of 26 512 Mm3/year in the basin.
Czynniki wpływające na przekaz języka mniejszościowego. Postawy wobec języka i ideologie językowe w narracjach rodziny na Górnych Łużycach

The transmission of languages in multilingual majority-minority contexts is influenced by language ideologies and language attitudes. In this paper I explore language ideologies in the Upper Sorbian Catholic community and languagepractices related to them. Based on biographic interviews with members of a linguistically mixed family, I also ask about the impact of overt strategies in everyday language choices. The family in question came to adopt a conscious family language policy based on the members’ positive attitudes towards Sorbian and based on their consciousness about community language practices that hamper the transmission of Sorbian in linguistically mixed environments. A positive attitude towards the minority language is a necessary, but not sufficient prerequisite to question habitual community language practices and consciously modify them. The families’ language behavior suggests that consciously modified language practices are adopted in certain domains, in this case mainly in that of the home.
