Published: March 2024

Industry in Indonesia is increasing, so companies are required to continue to focus on production. To obtain efficiency and company profits using outsourced employees from labor supply companies. Outsourced employees work for a company through a company providing labor. With the existence of a fixed-time work system, outsourced employees have concerns about their future. Several factors influence the emergence of job insecurity, including social support. Therefore, this study aims to determine the relationship between social support and job insecurity among outsourced employees. This study uses a quantitative correlational design. The sampling technique used is saturated sampling, with a total sample of 83 outsourced employees. The instruments used were a social support scale comprising 26 items, a quantitative dimension of the job insecurity scale of 3 items, and a qualitative dimension of 4 items. The social support scale has a reliability value of 0.886, a quantitative dimension of the job insecurity scale of 0.604, and a qualitative dimension of job insecurity of 0.786. The analysis technique uses the Pearson correlation with the help of data processing software. The research results showed that the correlation value of social support with job insecurity in the quantitative dimension was r = 0.338 with p = 0.002 <0.05. Furthermore, the qualitative dimension's correlation value of social support with job insecurity was r = -0. 228 with p = 0.008 < 0.05. These results show that the hypothesis proposed by the author is declared accepted even though the direction of the relationship is different.

Authors: Panja Eben , Hendry Hendry , Dewi Christine
Published: March 2024

Purpose: The purpose of this research is to detect vehicle types in various image conditions using YOLOv8n, YOLOv8s, and YOLOv8m with augmentation.Methods: This research utilizes the YOLOv8 method on the DAWN dataset. The method involves using pre-trained Convolutional Neural Networks (CNN) to process the images and output the bounding boxes and classes of the detected objects. Additionally, data augmentation applied to improve the model's ability to recognize vehicles from different directions and viewpoints.Result: The mAP values for the test results are as follows: Without data augmentation, YOLOv8n achieved approximately 58%, YOLOv8s scored around 68.5%, and YOLOv8m achieved roughly 68.9%. However, after applying horizontal flip data augmentation, YOLOv8n's mAP increased to about 60.9%, YOLOv8s improved to about 62%, and YOLOv8m excelled with a mAP of about 71.2%. Using horizontal flip data augmentation improves the performance of all three YOLOv8 models. The YOLOv8m model achieves the highest mAP value of 71.2%, indicating its high effectiveness in detecting objects after applying horizontal flip augmentation. Novelty: This research introduces novelty by employing the latest version of YOLO, YOLOv8, and comparing its performance with YOLOv8n, YOLOv8s, and YOLOv8m. The use of data augmentation techniques, such as horizontal flip, to increase data variation is also novel in expanding the dataset and improving the model's ability to recognize objects.

Mechanical Treatment of Pulp Fibers for Paper Property Development
Authors:   James River Corporation, KVP Group, Parchment, MI 49004, USA, Hartman Richard R.
Published: March 2024

Some fundamental aspects of mechanical actions on wood pulp fibers have been studied. Specifically, the objectives of the study were to produce internal fibrillation in pulp fibers, evaluate its influence on paper properties, and establish its importance relative to external fibrillation and fines in terms of paper property development. An apparatus was constructed that subjected pulp fibers (in the form of a wet handsheet) to repeated compressive loading cycles. Pulp was also treated in an experimental apparatus designed to promote external fibrillation, and in a Valley beater. Several fiber and paper properties were measured. The results showed that internal fibrillation could be produced with the repeated compressive action of the apparatus. The effect of internal fibrillation on paper properties caused a threefold increase in breaking length, from 2 km to 6 km. This level was 75% of the highest breaking length achieved with the Valley beater, which was 8 km. The reason for the difference in breaking length between the samples is due to the (calculated) differences in fiber-fiber bond shear strength. By adding fibrillation to internally fibrillated fibers and forming the sheet, no change in breaking length was achieved. However, adding fines to a suspension of internally fibrillated fibers increased the sheet breaking length, almost to the level produced by Valley beaten fibers. From these results, it was concluded that internal fibrillation in pulp fibers plays the largest part in improving sheet breaking length. Also, fines are a necessary supplement in the fiber network to improve interfiber bonding. The effect of external fibrillation had no apparent influence on improving breaking length, but its importance may lie elsewhere in the sheet forming process. Internal fibrillation and fines can be produced in separate steps, indicating an additive approach to developing sheet properties through refining is possible.
Studies of Polymorphy in Native Cellulose
Authors:   The Institute of Paper Chemistry, Appleton, Wisconsin, USA, Atalla Rajai H.
Published: March 2024

Our studies of cellulose structure based on X-ray diffractometry, Raman spectroscopy, and Solid State ¹³C-NMR have led us to a model which addresses questions of structure at two levels. The first is that of the organization of individual chains. Two stable ordered states of cellulose chains are postulated, together with a disordered state in which there is less coherence between the orientations of adjacent anhydroglucose rings. The ordered states are identified as kᵢ and kᵢᵢ based on their predominance in celluloses I and II, respectively; both conformations are based on the dimeric anhydrocellobiose as the basic repeat until in the ordered chain. The disordered state is identified as kₒ. The second level of organization is that of aggregation of chains into three-dimensionally ordered crystalline domains. At this level our model recognizes two crystalline forms within the native state. These are identified as Iα and Iß, the first found to be dominant in bacterial and algal celluloses, the second dominant in celluloses from higher plants. These two forms are found to contain chains possessing the same molecular conformation ᵏI, but the patterns of hydrogen bonding are found to be different. Cellulose II, which is derived from the native state by mercerization or regeneration at low temperatures, is found to consist predominantly of chains in the ᵏII conformation in yet a third distinct crystalline lattice.

Introduction: The interest in using cannabis and cannabinoids as a therapeutic tool has gained relevance in medicine in recent years. In line with this, interest in its study has increased in dentistry. The aim of the present narrative review was to analyze and synthesize the available information about the current therapeutic possibilities of cannabis in dentistry and its future perspectives. Materials and methods: an electronic search conducted that included articles until December 2022, in the MEDLINE, Scopus, Scielo and Google Scholar databases. The following main keywords used: “dental,” “dentistry,” “cannabis,” “cannabinoids,” “benefits,” “therapeutics,” “treatment,” “potential.” A total of 834 records founded in the first searches. Forty-five full-text articles assessed for eligibility. Thirty-five studies included for the qualitative analysis of the present review. Results: Studies show a great variability of cannabinoids and derivatives used, including commercial preparations, as well as experimental preparations. In vitro, in vivo, and clinical studies had conducted evaluating the action of cannabinoids in the control of orofacial pain, as anti-inflammatory and healing, in bone tissue regeneration, as antimicrobial and evaluating their anti-cancer ability. Conclusions: Cannabinoids have shown potential in the treatment of various oral conditions and/or disorders. Even the standardization of products and treatment protocols is insufficient, which is why more studies are necessary to evaluate presentations, derivatives, extraction methods, concentrations, and routes of administration for their best use.

Dialectology at Vilnius University
Authors: Judžentytė-Šinkūnienė Gintarė , Kardelis Vytautas
Published: March 2024

The paper aims to review the history of dialectology at Vilnius University since the establishment of the Department of the Lithuanian Language in 1940. To achieve this, we have set the following objectives: 1) to present the teaching of dialectology, 2) to review the dialect material collection, and 3) to examine existing research. Descriptive, analytical, and evaluative methods are applied in the study.

The beginning of dialectological research is associated with the name of Antanas Salys. The works of Aleksas Girdenis and Zigmas Zinkevičius are also discussed in the paper, as well as the teaching of the dialectology subject, methods of collecting dialectological material and directions of dialectological research. The paper distinguishes the paradigms of traditional, structural, and new dialectology dialectology, and examines their methodological similarities and differences.

The most important conclusions and summaries of the paper are fundamentally related to dialectological paradigms: in more than eighty years since the first dialectology subject taught at Vilnius University, the understanding of dialectology has changed. The stage of traditional dialectology at the University was extremely important, as it produced the most fundamental works that are still used today. The structural dialectology paradigm and Prof. Girdenis Dialectology School that trained a large group of productively working Lithuanian dialectologists has flourished over the years. Currently, the new paradigm of dialectology is making its way, offering new theoretical and methodological approaches to the study of dialects.
Lithuanian Language Curricula
Authors: Čepaitienė Giedrė
Published: March 2024

This article provides an overview of the general secondary school Lithuanian curricula. The very first curricula were developed as early as under the tsar’s rule (in 1906 and 1917). Once the Lithuanian state was restored, school curricula were usually published by the Ministry of Education, with individual schools only occasionally publishing a curriculum of their own. During the Soviet era, curricula were developed solely by the Ministry. Since the restoration of the Lithuanian independence in 1990, the Ministry has maintained its role of developing school curricula and so there have been just a few independently published curricula so far. Notably, curricula are typically anonymous. We know the authors of the first two curricula: the curriculum for the academic year 1905–1906 at Panevėžys Teacher Training Seminary was designed by Vladimiras Lukinas, and the following year, the curriculum for the same seminary was developed by Jonas Jablonskis. After 1990, curricula have usually been developed by working groups established by the Ministry; the lists of their members are publicly available. The article highlights the structure, didactic attitudes, and the organization of topics within the curricula, and demonstrates that the authors of the first curricula followed the descriptive work on the Lithuanian language already published at the time, whereas once the Ministry of Education began publishing curricula, they themselves became guidelines for textbook authors. The trend remains the same to this day.
The Official Lithuanian Language in the Interwar Years
Authors: Pupkis Aldonas
Published: March 2024

The article aims to show the state of the Lithuanian language in the years of the national movement at the turn of the 20th century and its functioning in the restored independent Lithuanian state from 1918 up to 1940 when it was occupied by the USSR.

Under the rule of the Russian Empire, the Lithuanian language was confined to the domestic setting: the press in the Latin script was banned and the use of Lithuanian in public was prohibited. As a continuation of the Springtime of Nations, the Lithuanian national movement relied on the Lithuanian-speaking society, and the language was perceived as one of the most important components of Lithuanianness. Scientific literature sometimes claims that the Lithuanian identity has been built on the philological foundation. This idea can be found in the history of many European nations, so the emphasis on the native language in Lithuania was nothing out of the ordinary.

Drawing on national legislation and archival data, the article outlines how the Lithuanian language was taking root in the state that declared its independence in 1918. Reform of the economy, development of culture and education, the choice of the Western way of life, and formalising Lithuanian as the official language in the 1922 Constitution, created favourable conditions for the Lithuanian language and culture to function independently in the entire public life.

The development of the Lithuanian language in the years of independence is analysed in three dimensions: legal (introducing the official language in all areas of life), structural (conducting research of the language, compiling the great dictionary, etc.), and educational (developing the modern theory of standard language grounded in structuralism and implementing its principles). The ideological basis of the educational work (as part of national upbringing), its implementers (the Lithuanian Language Society, different commissions and organizations), and the results thereof are also discussed.
Baltic Linguistics in Lithuania During a Century
Authors: Stundžia Bonifacas
Published: March 2024

The article reviews the research of Baltic linguistics, including ancient writing, in Lithuania from the 1920s to the early 21st century. The aim was to discuss the development of some of the more important areas, directions and methods of Baltic linguistics, linking it with changes in public life and conjuncture, as well as national culture, and highlighting significant works. It begins with relatively modest but ambitious pre-war research conducted by traditional philological and comparative historical methods. It goes on to look at the oppressive time of the post-war ideological dictatorship, when, in principle, only activities of a practical nature were possible. The period of the so-called Thaw (ca. 1954–1965) allowed for some fresh air and maturing of the elite of Baltic language researchers, which in the years of stagnation (ca. 1965–1985) mastered the methods of internal reconstruction and structural linguistics, published significant works on the history of language, etymology, onomastics and synchronical linguistics, including theoretical ones, laid the foundations of schools of phonology and word formation. The review concludes with an epoch of Soviet transformation and restored independence (ca. 1985 to the present), which liberated researchers and gradually led to international horizons. Research in applied linguistics, terminology, stylistics, rhetoric and some other directions was discussed by collegues.

Published: March 2024

In computed tomography, image quality tests are important to guarantee a correct medical diagnosis and a better cost and benefit for the patient. Purpose: the purpose of this study is to analyse the images reconstructed with different thorax and bone convolution filters using popular free-use software in the field of medical physics, for the Catphan 504 phantom. Methods: a total of 14 scans were performed using the chest protocol, with convolution filters (FC) FC30, FC35, FC50, FC51, FC52, FC53, FC55, FC56, FC80, FC81, FC83, FC84, FC85, FC86, on the 16-channel Canon Aquilion Lightning CT scanner using the Catphan 504 phantom. Image quality parameters evaluated were: noise, uniformity, linearity of CT numbers, and high spatial resolution with MTF 50% and MTF 10%. The images were evaluated using software such as ImageJ, Script Python, and free software for automatic evaluation of the Catphan 504 phantom, CTQA-cp, SPICE-CT, and Pylinac. Results: the tests carried out with the Catphan 504 phantom were analysed by the software and agreed with each other (with p>0.05), except for Pylinac. The results obtained with Pylinac had a significant difference for the uniformity, slice thickness, and MTF10% tests, this being the code that was the furthest away from the results obtained by the other codes. Conclusions: the ImageJ, Spice-CT, and CTQA-cp software showed consistent results for the tests performed, while Pylinac had limitations in calculating the standard deviation for the noise test and showed significant differences in some tests when compared to the other software.
The Effect of Throughflow and Gravitational Modulation on Weakly Nonlinear Bio-Thermal Convection in a Porous Medium Layer
Authors: Kopp M.I. , Yanovsky V.V.
Published: March 2024

We investigate the impact of periodically varying gravitational fields and a throughflow on the bio-thermal Darcy–Brinkman convection within a porous medium layer saturated with a Newtonian fluid containing gyrotactic microorganisms. The study includes an examination of two types of a throughflow: one directed against the gravity field and another one along it. We assume that the gravitational modulation has a small amplitude, quantified as a second-order smallness in the dimensionless parameter ϵ, which represents the supercritical parameter of the Rayleigh number. For weakly nonlinear convection, a Ginzburg–Landau (GL) equation with a periodic coefficient is derived in the third order in ϵ. To analyze the heat and mass transfer, we numerically solve the GL equation. The numerical results reveal that the vertical throughflow in the bio-thermal convection exhibits a dual nature, allowing for both augmentation and a reduction of the heat and mass transfers. We investigate the influence of variations in the Vadasz number, Peclet number, bioconvective Peclet number, frequency, and amplitude of modulation on the heat and mass transfer. The effects of these parameters are depicted graphically, illustrating that higher values of the Vadasz and Peclet numbers, as well as increased modulation amplitude, positively impact the heat and mass transfer. In addition, a comparative analysis of modulated and non-modulated systems shows a significant effect of the modulation on the stability of systems.

Features of the Generation and Use of Solid Waste in the Republic of Belarus
Authors:   Belarusian State Economic University, Tsvil Maria
Published: March 2024

The purpose of the work is to justify the priority of processing municipal solid waste over other solid waste. The methodology chosen is the analysis of statistical data characterizing the generation and use of solid waste in Belarus. It has been established that over 60% of solid waste in the Republic is generated as a result of the activities of OJSC Belaruskali, which specializes in the extraction of potassium salt and the production of mineral fertilizers. These production wastes are characterized by a low level of danger and are sent for temporary storage. Only 1.6% of all production waste generated is subject to burial, which in world practice is recognized as the least desirable method of disposal. Municipal solid waste accounts for about 6% of the mass fraction of all generated solid waste. However, the municipal solid waste segment accounts for 86% of all waste disposed of in landfills. There is a trend towards an increase in the share of municipal solid waste use from 9% in 2010 to 30% in 2021, which means a general decrease in the volume of waste disposal in Belarus. The growth in the use of municipal solid waste is hampered by its complex morphological composition, therefore, before using waste, it is advisable to sort it or separate collection. To improve monitoring of waste generation and use in Belarus, some additions to the existing statistical system of environmental indicators are also proposed.

Published: March 2024

The authors of the article conducted a study of trends in regional integration in the Russian Federation in the context of transformation processes and globalization changes in the world. The subject of the work is the trends in the regionalization of integration processes in the Russian Federation, taking into account the transformational external environment. In the context of the topic, the authors tried to show current trends in the interregional integration agenda using the example of the Ural Federal District of the Russian Federation in the context of strategic management of regional integration processes. The article proposes a methodological approach to the strategic management of socio-economic development of regions. The applicable research methods in the article were the method of systematization and generalization, as well as the method of content analysis. The proposed methodological approach to the strategic management of regional integration of the constituent entities of the Russian Federation allows us to develop an effective system of methods for making management decisions. Investigating the category of integration, the authors noted that it is closely related to the category of space, and also concluded that the more intense and varied the interaction between agents belonging to different territorial units, the higher the degree of integration. The socio-economic consequences of competition between the constituent entities of the Russian Federation for resources are of particular interest today in light of the extreme differentiation of regions and the growing gap between them. The study identified industries in the constituent entities of the Ural Federal District where regional integration is most actively observed. The authors of the article also found that interaction between regions is carried out through the transfer of functions in the field of housing policy, tourism, services and retail trade. The article identifies the main trends in regional integration in the areas of various types of interregional flows: imports and exports, migration, information, investments, and also evaluates the effects of regional integration.

Published: March 2024

The problem of increasing the quality of human life is multicomponent and multifaceted. In this context, there is a need to conduct scientific research that can comprehensively reflect the level of development of the state, assess the attractiveness of a country or region not only from an economic point of view, but also from the position of comfort, stability and people’s subjective perception of the state of civil society. This problem, according to the authors, is solved by studying life satisfaction. It involves analyzing and assessing the factors that determine the perception of a person’s quality of life in order to determine priorities in increasing the population’s life satisfaction. In this article, life satisfaction is understood as an individual’s subjective assessment of his economic and social situation. When determining the happiness rating, both objective socio-economic indicators and indicators of the development of civil society, including subjectively perceived ones, are used. The results of the analysis of life satisfaction can form the basis for the formation of macroeconomic policy of the state. Achieving high scores in the happiness rating creates an attractive image of the country, which has a positive effect on the establishment of favorable diplomatic relations and creates conditions for the influx of investments. The purpose of this article is to determine the level of influence of economic well-being on life satisfaction. The study carried out an analysis of macroeconomic indicators and indicators used in the formation of happiness ratings. Using the example of the economy of the Republic of Moldova, the effect of the Easterlin paradox is demonstrated. The authors calculated the correlation coefficient between GDP per capita indicators and the level of happiness, which showed the presence of a moderate, rather than strong, relationship between them.

The article discusses the problems that arose during the COVID-19 pandemic and the post-pandemic period related to the budgetary security of people's livelihoods. The purpose of the article is to show the need to resolve issues related to the decrease in budget revenues, which is reflected in the level of livelihoods of the population of the territories. To understand the problems that have arisen, the concepts of “budget sustainability” and “fiscal security” are identified, and the author’s point of view regarding the nature of these concepts is proposed. The authors hypothesized that the quality of budget planning affects the level of budgetary security of people, and, consequently, their level of living. And this type of problem can be minimized using methods used to solve socially oriented problems. In the author's study, special emphasis is placed on the ideology of territorial assessment, which is based on an indicative approach. A methodological approach to express assessment of the level of budgetary security of people's livelihoods based on an analysis of relative budget indicators is proposed. The assessment was carried out comparatively across twenty regions and showed mixed results, but most regions experienced a deterioration in budgetary security not only during the pandemic period, but also in the post-pandemic period. The fact has been revealed that the process of formation of budget funds and their further distribution occur in uncertain conditions. The main conclusions of the authors prove that during the pandemic and post-pandemic impact on the budgetary security of people's livelihoods, regional and local authorities are faced with difficult tasks in preventing and eliminating socially oriented problems.

The use of artificial intelligence is becoming one of the development trends in the financial industry. Many companies have already mastered the first directions of the application of artificial intelligence and are now looking for new ways to use this technology. The article analyzes the current state, development trends, prospects and risks of introducing artificial intelligence technologies into the work processes of Russian banks. The dynamics of the Russian artificial intelligence technology market for 2022 are presented, examples of practical business solutions using these technologies in marketing are given, and their advantages and disadvantages are highlighted. The purpose of the article is to identify the risks and prospects for the development of artificial intelligence technologies in the banking sector based on an assessment of the current results of using this technology in banks and the opinions of their clients. Based on the author's survey of respondents, a study of attitudes towards such changes was conducted. The survey results showed that the younger generation is ready to interact with artificial intelligence systems, but at the same time there is still distrust in the solutions and products offered on their basis. The first results of introducing artificial intelligence technologies into business processes are presented using the example of Sberbank, which, being the largest Russian bank, is actively developing and implementing this technology into its systems and products. Thus, the scope of artificial intelligence will expand and cover new directions, facilitating labor-intensive and routine tasks for personnel. Companies and banks without the introduction of artificial intelligence into business processes may lose their competitiveness in the future.
Application of generalised functions and Fourier’s integral transformation in modelling the effect of a moving load on a beam resting on an elastic foundation

Published: March 2024

The paper is dedicated to modelling the behaviour of an infinitely long beam resting on a solid elastic foundation under the concentrated moving load effect. The modelling is carried out in the context of determining the high-speed vehicle stock impact on the track structure. When developing the method of
problem solving, the known elasticity theory factors,
wave-propagation theory, complex variable theory, as well as integral transformations of generalised functions were used. The mobile concentrated force is represented by the Dirac delta function. The Fourier’s integral transformation is used to solve the equation of motion and determine the beam defect. Contour integration using Cauchy residue theorem is applied to calculate the defect values in the original space. The general dependence form the beam defect on the load velocity is determined. It is shown that the defect values in the beam increase with moving load increasing speed. It is shown how the moving load velocity affects the character of the beam defect time dependence. Solutions are given for
Euler-Bernoulli, Rayleigh and Timoshenko models of beams on an elastic base. The considered mathematical models behaviour is compared. It is shown that the character of beam interaction with the moving load, the defect values, as well as the reaching critical velocities character do not differ significantly for the considered beam models. The character of reaching the maximum defect in the application area of the mobile load is analysed. It is shown that the maximum defect values of beams on an elastic base occur after the moving load. The presented methodology can be used to evaluate the impact of rolling stock on the track structure, including the design of high-speed lines.

One of the most important consumer properties of a highway is traffic safety. In order to organize traffic flows and ensure safety on highways, technical means of traffic organization are used, which include horizontal road markings. The presence of easy-to-read marking schemes, especially on roads without artificial lighting, as well as in low visibility conditions, contributes to ensuring the cars safety traffic and pedestrians in accordance with the road traffic regulations. This work devoted to the dependence study of changes in the lighting parameters of horizontal road markings on technological, operational and other factors. Emphasis in the work is made on the analysis of changes in the light transmission coefficient, as this parameter is a markings visibility indicator in darkness hours. As in the darkness hours period most of the road accidents occur, which have the most severe consequences. The article analyzes foreign studies concerning the reasons for the lighting markings parameters reduction and the statistical dependencies establishment describing this process. The authors have carried out experimental studies of the road markings degradation process on public roads of II and III categories in the Moscow Region. Based on the experimental results, the influence of technological and operational factors on the road markings lighting characteristics deterioration is evaluated. The analysis was performed for different road marking lines applied by thermoplastic and cold plastic. According to the study results recommendations are given to ensure the required values of such lighting characteristics as retroreflection coefficient when applying horizontal road markings.

The article considers the road pavement reinforcement method with the use of bottom-ash mixtures. In the introductory part, there is an explanation about the conducted experimental works on road pavement strengthening with the cement, bottom-ash mixtures compositions base and stabilising additives (ANT, cryogelite, bitumen emulsion). The monitoring results of the motorway condition (2015–2022), reinforced with bottom-ash mixtures with photo committing changes and technical and economic assessment of the proposed solutions are given. Test section condition monitoring was carried out in accordance with Road industrial methodical document 218.0.000-2003 «Guidelines for assessing the level of maintenance of motorways». Technical and economic assessment is based on the Federal Unit Rates. The comparative options cost with the soil transportation distance of 10 km and cement, bottom-ash mixture, ash, and additives — 100 km in base prices of Federal Unit Rates 2001 has been calculated. Dependences of the road pavement construction cost on the cement transportation method and distance, bottom-ash mixture, ash, and additives transportation at the distance to the soil bank from 4 to 10 km have been constructed. Monitoring results showed that cement-soil road pavement with bottom-ash mixtures can be effectively used as a base for IV technical category motorways, but it is necessary to arrange a layer of pavement for its protection.

This study focused on the distribution of algae in the saline coastal water bodies of Pryazov National Nature Park according to their habitat preferences. This research revealed that aquatic species form the basis of the algal flora. Among these, diatoms were predominant in terms of species richness and frequency of occurrence. In the lake-type estuaries and ephemeral water bodies, an increased number of amphibious species were found, which can be attributed to the fluctuating water level. Among the amphibious species, Cyanoprokaryota representatives dominate. Hierarchical clustering of the water bodies demonstrated a connection between the species composition of algae and the type of water body, which is consistent with their genesis and transformation.
