Scaling of damage mechanism for additively manufactured alloys at very high cycle fatigue

A comparative analysis of fracture mechanisms in high- and very high- cycle fatigue (HCF, VHCF) regimes was carried out based on the results of multifractal analysis of the fracture surfaces of additively manufactured 316L stainless steel samples. In terms of scale invariants, the morphology of fracture surfaces in HCF and VHCF regimes inside and outside the fine granular area is shown. The analysis demonstrated that chaotic patterns of relief formation prevail in the crack initiation zone of VHCF samples. However, there is a self-similar relief with a pronounced correlation in the crack propagation area. The relief of the crack growth areas for HCF and VHCF samples are similar to each other.

FEATURES OF THE FORMATION OF THE NANOSTRUCTURAL STATE OF THE SURFACE LAYER OF STEEL PARTS DURING PROCESSING AND OPERATION

Considered patterns of formation of the nanostructural state of the surface layer of machine parts during friction under conditions of complex dynamic loading. The results of the complex assessment of the state of the surface layer of samples after friction continuous indentation and scanning methods indenter, an analysis of changes in the work function of the electron from the surface of the samples. Shown that during the friction of steel surfaces, an increase in transverse slippage contributes to the formation of a more uniform surface layer. This decreases its strength, wear resistance, and a more uniform surface microgeometry. This is accompanied by a decrease in the magnitude and spread of the electron work function over the surface. The relationship between the nanostructural state of a polished surface and roughness and reflectivity is presented.

Integrated Transcriptomic and Metabolomic Analysis Reveal the Dynamic Process of Bama Hemp Seed Development and the Accumulation Mechanism of α-Linolenic Acid and Linoleic Acid.

Bama County is a world-famous longevity county in the Guangxi Province, China. Bama hemp is a traditional seed used in hemp cultivation in the Bama County. The seeds contain abundant unsaturated fatty acids, particularly linoleic acid (LA) and linolenic acid in the golden ratio. These two substances have been proven to be related to human health and the prevention of various diseases. However, the seed development and seed oil accumulation mechanisms remain unclear. This study employed a combined analysis of physiological, transcriptomic, and metabolomic parameters to elucidate the fatty acid formation patterns in Bama hemp seeds throughout development. We found that seed oil accumulated at a late stage in embryo development, with seed oil accumulation following an "S″-shaped growth curve, and positively correlated with seed size, sugar content, protein content, and starch content. Transcriptome analysis identified genes related to the metabolism of LA, α-linolenic acid (ALA), and jasmonic acid (JA). We found that the FAD2 gene was upregulated 165.26 folds and the FAD3 gene was downregulated 6.15 folds at day 21. Metabolomic changes in LA, ALA, and JA compounds suggested a competitive relationship among these substances. Our findings indicate that the peak period of substance accumulation and nutrient accumulation in Bama hemp seeds occurs during the midstage of seed development (day 21) rather than in the late stage (day 40). The results of this research will provide a theoretical basis for local cultivation and deep processing of Bama hemp.

Comprehensive Profiling of Klebsiella in Surface Waters from Northern Portugal: Understanding Patterns in Prevalence, Antibiotic Resistance, and Biofilm Formation

This study investigates the prevalence of resistance and virulence genes in Klebsiella isolates from surface waters in Northern Portugal, within the broader context of freshwater quality challenges in Southern Europe. The aim of this research is to explain how Klebsiella dynamics, antibiotic resistance, and biofilm formation interact in surface waters. Antimicrobial susceptibility was examined using the Kirby–Bauer disk diffusion method against 11 antibiotics and screening for Extended-Spectrum Beta-Lactamase (ESBL) production using the double-disk synergy. PCR was employed to detect resistance and virulence genes, while biofilm production was assessed using the microplate method. Out of 77 water isolates, 33 Klebsiella (14 Klebsiella spp. and 19 K. pneumoniae strains) were isolated. ESBL production was observed in 36.8% of K. pneumoniae and 28.6% of Klebsiella spp. High resistance rates to blaCTX-U were observed in both. The papC gene was prevalent, signifying potential environmental risks. Biofilm production averaged 81.3% for K. pneumoniae and 86.9% for Klebsiella spp. These findings underscore the intricate interplay between Klebsiella’s dynamics and freshwater quality, with ESBL’s prevalence raising concerns about waterborne dissemination and public health implications. This work supports the need for vigilance of Klebsiella in surface waters in Southern Europe.

Project portfolio formation as an organizational routine: patterns of actions in implementing innovation strategy

Implementing strategy through an innovation project portfolio starts with project portfolio formation. The routine of project portfolio formation is especially influential, as it includes identifying, screening, and prioritizing the projects that shape the eventual portfolio. Comprehensive understanding of the project portfolio formation routine is important for addressing the simultaneous pressures for continuity and renewal when implementing innovation strategy. This study explores portfolio actors’ behavioral patterns in the project portfolio formation routine to understand their contextuality and implications on innovation strategy implementation. A multiple-case study with innovative companies reveals a comprehensive framework of governing and empowering actions and organization-specific patterns of actions. Differences between organizations in the combination of governing and empowering actions may be explained by innovation types, and the size and history of the organization. The behavioral patterns of project portfolio formation can provide organizations with a foundation for implementing both continuity- and renewal-oriented innovation strategies.

Progress and landscape of disaster science: Insights from computational analyses

This study identifies trends in disaster science research as well as knowledge gaps at a broad scale in order to help underpin and inform future research in the area. A numerical analysis of 58,106 peer-reviewed articles over four decades reveals key research themes and clusters, their temporal variation of activity as well as the influential studies that have played a key role in their development. Results indicate that what we recognize as contemporary disaster science has only shown discernible patterns of activity and knowledge foundation formation since the 1990s. Disaster research currently constitutes approximately 0.23% of all academic papers published per year. The initial and intermediate phases of the development of the field have been unsystematic and fragmented, with the focus of the field fluctuating for almost two decades until recently when research clusters have shown signs of stabilizing. It is observable that, over the last few years, more attention has been allocated to mitigation, response and recovery by focusing on issues such as the psychological impacts of disasters, reducing exposure to disasters and building community resilience to cope and recover from disasters. This is in contrast with earlier years where the focus was predominantly on preparedness and prevention. Research in different countries has been highly correlated with the types of disasters that occur in their regions, highlighting the relevance of the local situatedness and context in disaster research. The recent emergence and explosive growth of a research cluster linked to flood detection, flood mapping and flood hazard assessment is particularly notable, marking the sharpest growth of a single research cluster ever recorded in this field. A similar trend, though of a smaller magnitude, is observable in relation to research on wildfire hazard. Overall, flood-related research has proven one of the dominant themes, with multiple clusters detectable on the topic, each with their own distinguishable knowledge foundation (i.e., set of references). The pattern of collaboration among disaster researchers is shifting from predominantly domestic research towards international collaborations (currently reaching about 1/3 of all disaster-related papers each year), a sign of recognition to the value of cross-cultural and interdisciplinary perspectives in disaster research.

Formation of the first plane of division relative to the pronuclear axis predicts embryonic ploidy

Research QuestionThis study aimed to examine the relationship between the position of male and female pronuclei immediately before the loss of the pronucleus (pronuclear axis) and the formation of the first-division plane in human pronuclear-stage embryos, and its effects on ploidy and clinical pregnancy rates. DesignTransferred embryos were followed up until their prognoses. A total of 762 embryos formed two cells and reached the blastocyst stage after normal fertilisation in a time-lapse incubator. Embryos were classified into three groups: group A, comprising embryos in which the first plane of division was formed parallel to the axis of the pronucleus; group B, comprising embryos in which cases of oblique formation were observed; and group C, embryos in which cases of perpendicular formation were observed. ResultsThe euploidy rate was significantly higher in groups A and B than those in group C (P < 0.01), whereas the aneuploidy rate was significantly higher in group C (P < 0.01) than in groups A and B. There were no differences between the three groups in terms of the frequency of positive human chorionic gonadotropin-based pregnancy tests, frequency of clinical pregnancies, miscarriage rates, or delivery rates. Conclusions: The formation pattern of the first plane of division relative to the pronuclear axis was a predictor of embryonic ploidy, with a reduced rate of euploidy and a high probability of aneuploidy observed when the first plane of division was perpendicular to the pronuclear axis.

Ukrainian historical terminology designating social and military status in Old Rus': Examining their counterparts in English

The article researches translators' challenges in rendering domain-specific terms which include culture-specific items. The study has been carried out using Old Rus' historical terminology employed to designate social and military status. It was selected en masse from academic texts, using monographs and academic articles in both languages. 82 language units representing culture-specific historical terms related to social, political and military organisation of the society of that period were chosen and described in terms of appropriate translation. Our hypothesis has been tested as to the unacceptability of approximation (analogous translation and generalisation) in rendering culture-related terms that designate highly specific concepts of the defined period in Ukrainian history. The research establishes that approximate translation fails to meet the requirements of strict definition and accuracy demanded by professional terminology. Our study underlines the importance of secondary term formation, descriptive translation, and the method called combined renomination (transcription and description combined). For a translation to be accurate, the shift in translation should follow the shift in concept. The specific term may have wider, more general semantics, and in each particular context it should be specified. The use of the description or combined renomination helps to make the meaning of the concept clearer.  The study demonstrates that the most accurate and effective secondary term formation usually follows the pattern of term formation in the original language.

Lions & sea lions & bears, oh my: utilizing museum specimens to study the ossification sequence of carnivoran taxa

BackgroundMammalian skeletons are largely formed before birth. Heterochronic changes in skeletal formation can be investigated by comparing the order of ossification for different elements of the skeleton. Due to the challenge of collecting prenatal specimens in viviparous taxa, opportunistically collected museum specimens provide the best material for studying prenatal skeletal development across many mammalian species. Previous studies have investigated ossification sequence in a range of mammalian species, but little is known about the pattern of bone formation in Carnivora. Carnivorans have diverse ecologies, diets, and biomechanical specializations and are well-suited for investigating questions in evolutionary biology. Currently, developmental data on carnivorans is largely limited to domesticated species. To expand available data on carnivoran skeletal development, we used micro-computed tomography (micro-CT) to non-invasively evaluate the degree of ossification in all prenatal carnivoran specimens housed in the Harvard Museum of Comparative Zoology. By coding the presence or absence of bones in each specimen, we constructed ossification sequences for each species. Parsimov-based genetic inference (PGi) was then used to identify heterochronic shifts between carnivoran lineages and reconstruct the ancestral ossification sequence of Carnivora.ResultsWe used micro-CT to study prenatal ossification sequence in six carnivora species: Eumetopias jubatus (Steller sea lion, n = 6), Herpestes javanicus (small Indian mongoose, n = 1), Panthera leo (lion, n = 1), Urocyon cinereoargenteus (gray fox, n = 1), Ursus arctos arctos (Eurasian brown bear, n = 1), and Viverricula indica (small Indian civet, n = 5). Due to the relatively later stage of collection for the available specimens, few heterochronic shifts were identified. Ossification sequences of feliform species showed complete agreement with the domestic cat. In caniforms, the bear and fox ossification sequences largely matched the dog, but numerous heterochronic shifts were identified in the sea lion.ConclusionsWe use museum specimens to generate cranial and postcranial micro-CT data on six species split between the two major carnivoran clades: Caniformia and Feliformia. Our data suggest that the ossification sequence of domestic dogs and cats are likely good models for terrestrial caniforms and feliforms, respectively, but not pinnipeds.

Thermodynamic analysis of natural gas/hydrogen-fueled compressed air energy storage system

In this paper, a diabatic compressed air energy storage system fueled by a natural gas/hydrogen mixture that integrates heating and power generation is proposed. A comprehensive thermodynamic analysis has been conducted to identify the key factors influencing system performance and elucidate the detailed formation and distribution patterns of irreversible losses when utilizing a hydrogen-natural gas blend as fuel in the proposed system. The research results indicate that increasing the hydrogen blending ratio from 0.5 to 1 lead to greater enhancements in roundtrip efficiency (∼1.08% vs. ∼0.33%), exergy efficiency (∼3.88% vs. ∼1.15%), and energy density (∼1.24% vs. ∼0.42%) compared to an increase from 0 to 0.5. The combustor suffers the largest exergy destruction proportion, with a notable reduction in exergy destruction achieved through increased hydrogen blending. System performance benefits significantly from higher combustor outlet temperatures and expansion ratios at various hydrogen blending ratios. The rate of change in exergy efficiency (∼42.76% vs. ∼83.17%) and energy density (∼58.83%) demonstrates an inverse correlation with the varied parameters (1100–1500K, 4–8), except for the rate of change in energy density (∼6.76%), which displays a positive relationship with the combustor outlet temperature. Notably, a significant decrease in the rate of change in roundtrip efficiency (∼1.87% vs. ∼6.64%) is observed within a specific parameter range (1400–1500K, 5–6). Sensitivity analysis identifies the combustor outlet temperature as the most influential factor in enhancing system performance, consistently showing positive effects of the hydrogen blending ratio.

Straw-derived biochar incorporation improves seedcotton yield and fiber quality by optimizing photosynthetic carbon and nutrients partitioning and boll formation patterns

Synergistic improvement of cotton (Gossypium hirsutum L.) yield and quality is necessary to meet the demands of the textile industry. Straw or biochar addition has been shown to increase boll number and hence yield, while optimizing reproductive growth processes (e.g., accelerating boll formation during the effective boll-setting period) is essential for improving fiber quality. However, it remains unclear how straw and biochar affect boll formation dynamics and whether they can simultaneously improve cotton yield and fiber quality. In order to reveal the mechanism of simultaneous improvement of cotton yield and quality, this study investigated the responses of plant photosynthetic carbon allocation, bud and boll dynamics, seedcotton yield, and fiber quality to different straw returning modes. A 7- year field experiment was performed with four straw treatments: no straw or biochar addition (CK); straw-derived biochar incorporation (SBI); straw incorporation (SI); and straw mulching (SM). The results suggested that SBI, SI and SM remarkably increased the seedcotton yield (24.5–30.7 %, 12.6–20.4 % and 4.7 %-11.0 %), fiber length (3.6–6.7 %, 4.0–9.5 % and 2.4–7.1 %) and fiber strength (8.0–13.0 %, 6.2–10.7 % and 4.4–5.7 %) from 2019 to 2021, compared with CK. There was a strong consistency between seedcotton yield and fiber strength among straw returning modes, and were highest under SBI, followed by SI and SM. Compared with CK, SBI significantly increased nutrients and photosynthetic carbon accumulation in cotton plant, and enhanced their distribution proportion in reproductive organs. This increased the number of fruiting branches, number of fruiting sites and ratio of fruiting sites to fruiting branches, accelerated budding and reduced the shedding rate of buds and bolls. Finally, SBI obtained the highest boll forming rate during the boll formation stage, as well as the highest effective boll number at the harvest stage. Overall, returning straw-derived biochar into soils optimized the allocation of nutrients and photosynthetic carbon in cotton plant, and accelerated the formation of cotton bolls from peak flowering stage to peak boll setting stage, thereby improving seedcotton yield and fiber quality. This work provides practical guidance for improving seedcotton yield, fiber quality, and the utilization of straw resources.

Formation mechanism of high-altitude glacial mineral water in the Kunlun Mountains of Tibetan Plateau: Insights from isotopes and hydrochemistry

Study regionThe Kunlun Mountains on Tibetan Plateau Study focusThe Tibetan Plateau, well known as Asian Water Tower, holds immense potential for the formation of glacial mineral water. The present research focuses on the hydrochemical and isotopic signatures and formation pattern of natural glacial mineral water in the alpine region on Tibetan Plateau. New hydrological insights for the regionThe investigated mineral groundwater has outstanding water quality and slightly alkaline nature. It is with fresh hydrochemical facies of HCO3-Na·Ca type with total dissolved solids (TDS) in the range of 384–964 mg/L, and featured by notably rich strontium with the concentrations of 0.67–0.81 mg/L, far exceeding the recommended mineral water minimum threshold of 0.20 mg/L. The mineral groundwater is originated from the glacier meltwater of mountainous area with elevation over 4500 m. It subsequently infiltrates into the bedrock and move within the groundwater system with a residence time of approximately 52 years. Its hydrochemical constituents are naturally governed by water-rock interactions of silicates dissolution, cation exchange, and celestite and strontianite dissolution. A conceptual model is proposed to outline the formation pattern of glacial mineral water in alpine region on Tibetan Plateau. Findings of this study can fill the study gap regarding glacial mineral water on Tibetan Plateau, and further contribute to the future study and development of natural glacial mineral water in alpine regions worldwide.

Development of a method for the determination of alkylpyrazine in traditional vinegar and its formation kinetics

Alkylpyrazine (APZ), as one of the crucial components in food flavor, are extremely important for the sensory evaluation of foods. For the purpose of simultaneously identifying multiple APZ in food items, a HPLC analytical method was created. The chromatography was carried out on an XBridge C18 column at a flow rate of 1 mL/min, with a detection wavelength of 275 nm. The ratio of mobile phase A (acetonitrile) to mobile phase B (0.1% formic acid and 0.1% aqueous trifluoroacetic acid) was 1:99. Compared to the conventional assay, RSD of precision less than 3%, average recoveries ranged from 96% to 110%, quantification limits were between 0.052 and 0.278 mg/L, detection limits were between 0.016 and 0.084 mg/L, and total analysis time is 35 min in the HPLC method. Meanwhile, we found that prolonging the aging time could increase the flavor characteristics of vinegar by analyzing the composition of APZ in vinegar and its formation pattern during the brewing process. The above results demonstrated that HPLC is an effective method for the rapid determination of pyrazines in vinegar. This study provides a technical way for further focusing on the characteristic flavor components of vinegars or other fermentation products.

Intra-uterus phthalate exposure, ROS formation and altered mitochondrial D-loop methylation pattern at birth as potential triggers and markers of Alzheimer’s disease

Alzheimer's Disease is one of the fastest growing causes of dementia, and the factors that trigger its pathology have not yet been completely unraveled. In addition, Alzheimer's disease (AD) impacts not only the individual affected, but also the familial and socio-economic spheres. On the other hand, phthalates are plasticizers capable of interfering with the endocrine system and which, due to the nature of the most varied objects, utensils and tools used by society, as well as the propensity of these chemicals to dissociate from their matrices and accumulate in the environment and living organisms, are frequently and in large quantities exposed to humans. This study explores a possible relationship between exposure to phthalates and the development of Alzheimer's pathophysiology, with emphasis on prenatal exposure and its influence on the risk of dementia in adulthood. Based on the literature consulted, mechanisms for the generation of oxidative stress in the nervous system by phthalates were described and it was proposed how this could be related to the triggering of Alzheimer's pathophysiology, primarily in view of the modification of the methylation pattern of mitochondrial DNA. In addition, it was observed that exposure to phthalates during intrauterine life is capable of generating changes in the epigenetic pattern at birth. An alternative for the early detection of mitochondrial metabolic dysfunctions, which could potentially evolve into dementia, could involve monitoring D-loop methylation levels. Therefore, we hypothesized that intrauterine exposure to phthalates may generate oxidative stress in the brain and alter the mtDNA methylation pattern, which can perturb mitochondrial function and increase risk of development of AD at adulthood. We suggest that these phthalate-induced metabolic changes may be detected by the D-loop methylation pattern at birth. We highlight the need for more research integrating the emerging fields of mitoepigenetics and bioenergetic medicine with neurodegenerative diseases, and an experimental design employing zebrafish as a model is suggested to test the hypotheses raised.

Effect of the Energy Director Material on the Structure and Properties of Ultrasonic Welded Lap Joints of PEI Plates with CF Fabric/PEI Prepreg

To estimate the possibility of using both low-melting TecaPEI and neat PEI films as energy directors (EDs) for ultrasonic welding (USW) of carbon fiber (CF) fabric–polyetherimide (PEI) laminates, some patterns of structure formation and mechanical properties of their lap joints were investigated by varying the process parameters. The experiment was planned by the Taguchi method with the L9 orthogonal matrix. Based on the obtained results, USW parameters were optimized accounting for maintaining the structural integrity of the joined components and improving their functional characteristics. The use of the low-melting EDTecaPEI film enabled US-welding the laminates with minimal damage to the fusion zone, and the achieved lap shear strength (LSS) values of ~7.6 MPa were low. The use of EDSolverPEI excluded thermal degradation of the components as well as damage to the fusion zone, and improved LSS values to 21 MPa. With the use of digital image correlation (DIC) and computed tomography (CT) techniques, the structural factors affecting the deformation behavior of the USW lap joints were justified. A scheme was proposed that established the relationship between structural factors and the deformation response of the USW lap joints under static tension. The TecaPEI film can be used in USW procedures when very high interlayer adhesion properties are not on demand.

This research discusses the role of parents in the development of early childhood speech acts. The aim of this research is to investigate the role played by parents in the development of early childhood speech acts. This study was carried out using a qualitative approach by collecting data using observation, interviews and document analysis. The research participants consisted of ten families with children aged 3-5 years taken from various social and economic backgrounds. The research results show that the role of parents has a significant impact on the development of children's speech acts, including vocabulary formation, speaking abilities, and social communication patterns. Factors such as parent-child interactions, communication patterns within the family, and the social environment also influence the development of children's speech acts. The implication of these findings is the need for greater attention to the role of parents in supporting early childhood language and communication development through educational programs and social support for families.

Проблема осмысления целостности и онтологической дифференцированности техники

The article poses two questions. First, how should we think about the integrity of technology, given that it consists of very different entities (phenomena)? What, for example, do tools, technical structures, mechanisms, machines, the technical environment, and technology have in common? The answer that all these phenomena are artifacts created by man, who spied and enhanced the effects of nature, is clearly insufficient. Secondly, what relationships connect the listed types of technology? To answer, the author analyzes several cases (the formation of the ancient Egyptian pyramids, the prerequisites of the first industrial revolution, the formation of engineering, technology, A. Bogdanov’s theory “Tektology”), using the methodology of cultural and historical reconstruction developed by him, which in turn relies on the means of a number of humanitarian and social sciences. Sci. He shows that the implementation of this methodology makes it possible to characterize not only the patterns of formation of different types and essences of technology, but also to describe their unique features (singular aspect), as well as to understand the relationships they have.

Reservoir Characteristics and Formation Model of the Bauxite Gas Reservoir: The Benxi Formation in the LX Block, Northeast of Ordos Basin, China.

Recently, horizontal well L47-1CH in the Longdong area of the southwestern Ordos Basin made a significant breakthrough in bauxite natural gas exploration, changing the traditional geological understanding that bauxite could not form effective reservoirs. To further explore the exploration and development potential of bauxite natural gas reservoirs in the northeast of the Ordos Basin, it is urgent to carry out basic geological studies. This paper discusses the sedimentary environment, reservoir characteristics, and formation patterns of the bauxite gas reservoirs in the LX Block using trace elements, thin sections, X-ray diffraction, scanning electron microscopy, conventional physical properties, constant pressure mercury, etc. Then, the distribution pattern of bauxite was studied according to the restoration of the karst paleogeomorphology, and the formation model of bauxite was ultimately established. The results show that bauxite developed a clear triple-segment structure vertically, characterized by rich iron at the bottom, high aluminum at the middle, and low iron at the top. The mineral composition of the bauxite section mainly includes diaspore, iron minerals, titanium minerals, and birnessite. The types of pores mainly include intra- and intergranular dissolved pores, matrix-dissolved pores, intercrystalline pores, and microfractures. The porosity ranges from 1.51 to 9.90%, with a relatively good sorting and connectivity of the pore and throat. The bauxite was formed in a hot and humid climate, deposited in a shallow-water tidal flat and lagoon sedimentary environment with oxygen depleted, and experienced oscillatory regression during the deposition process. The thickness of bauxite is significantly controlled by karst paleogeomorphology, and it is mainly distributed at the negative terrain positions of karat pits and karst terraces. The above results can provide a geological basis for the exploration and development of bauxite in the Ordos Basin and similar basins worldwide.

The history of the development of the institute of judicial administrative and legal protection of human rights

The article examines the history of the development of the Institute of Judicial Administrative Legal Protection of Human Rights. The socio-economic, political-legal, ideological relations that formed in Ukraine in the period from the beginning of the 18th to the middle of the 20th century were chosen as the object of the study. In addition, which had a decisive influence on the development of ideas about judicial protection of human rights. The subject of the research is political and legal views on judicial protection of human rights. The methodological basis is the principles of historicism, scientificity and objectivity. Problem and comparative research methods were most intensively used. Development of the topic and interpretation of the studied material were carried out taking into account the peculiarities of the analyzed period. When solving the assigned tasks, he followed a complex approach to the analysis of legal phenomena. The chronological boundaries of the study are determined by what was formed at the end of the 18th to the middle of the 20th century. the political and legal opinion in Ukraine regarding the protection of human rights, within the framework of administrative proceedings in particular, has undergone a significant evolution. The political and legal opinion on the implementation of the protection of human rights against the arbitrariness of state authorities formed the basis of the reform of the judicial system, and in the process of this transformation, a new link appeared in the judicial system - the administrative court. It is indicated that the theoretical, practical and didactic significance of the problem is due to fundamental changes in the life of Ukrainian society in the context of integration into the European Union, in which the highest value is recognized as a person, with his status, rights and obligations. It is noted that the construction of a harmonious system of human rights and responsibilities, and, most importantly, the establishment of a mechanism for their real implementation are directly dependent on a comprehensive study of the patterns of formation, formation and functioning of rights and responsibilities, starting from the moment of their inception and up to the present time, which will allow to identify the peculiarities of their further development, to determine the place of rights and obligations in the system of legal values, as well as to identify the prerequisites of existing problems in their implementation and to propose ways to overcome them.
