The article deals with the definition of the term “rough axle” (profile billet). Among other things, data on the manufacturing process of axle billets, as well as manufacturing methods for rough axles in Ukraine are presented. Rough axles in our country are manufactured using three different methods of hot-forming process: free forging, screw rolling and radial-rotation profile forming. New method of manufacturing a pre-machined rough axle is described. References to the paper, i.e., determination of comparative characteristics of internal defects of different types of rough axles produced by several domestic manufacturers using various methods and technological processes are made. These characteristics were determined by the Testing Center for railcar-building products of DP "UkrNDIV" during different types of testing rough axles manufactured in the period from 2002 to 2017. The testing is described and the parameters of the test objects which were determined, namely, geometrical dimensions, surface integrity, marking, testing of sound permeability and internal defects of the axles, chemical composition and mechanical characteristics of the axle structure, macrostructure cleanliness, nonmetallic inclusions in the steel, micrographic cleanliness are indicated. Also, the testing results of pre-machined rough axles, manufactured by the method of turning the round billet, carried out by the Testing Center of DP "UkrNDIV" in the period from 2018 to 2021 are presented. Findings based on the tests results are set forth, that is, the tested parameters of test objects meet the requirements of regulatory documentation, steel-melting and manufacturing technological processes for rough axles manufactured by PJSC "INTERPIPE NTRP" comply with DSTU HOST 31334:2009, DSTU HOST 4728:2014 and TU U 30.2-23365425-701:2018. The list of literature sources including state standards and technical specification used while writing the paper and the article itself are given.

Most historical marine pollution monitoring has proven useless in a management context. A strategy for development of effective marine pollution monitoring programs is outlined. This strategy is based on the following steps: 1) systematic evaluation of the management information needs, 2) identification of the hypothetical impacts associated with those management concerns, and 3) investigation of the feasibility of monitoring those effects such that the existence, or absence, of a specified level of effects can be established in a statistically-valid manner. There are two fundamentally different types of monitoring program: site-specific and regional. These two types of program differ markedly in scope and approach when designed through application of this strategy. The strategy requires development of null hypotheses which address management concerns and which are amenable to scientific testing. In order for the program to be successful, the null hypotheses selected for inclusion in a marine pollution monitoring program must address levels of effect which are predefined to be environmentally significant. The definition of environmentally significant effect levels is a difficult process which must be primarily the responsibility of the managerial community.

3D Representations

Abstract3D modelling of man-made objects is widely used in the cultural heritage sector, among others. It is relevant for its documentation, dissemination and preservation. Related to historical fabrics, weaves and weaving techniques are still mostly represented in forms of 2D graphics and textual descriptions. However, complex geometries are difficult to represent in such forms, hindering the way this legacy is transmitted to new generations. In this paper, we present the design and implementation of SILKNOW’s Virtual Loom, an interactive tool aimed to document, preserve and represent in interactive 3D forms historical weaves and weaving techniques of silk fabrics, dating from the 15th to the 19th centuries. To that end, our tool only requires an image of a historical fabric. Departing from this image, the tool automatically subtracts the design, and allows the user to apply different weaves and weaving techniques. In its current version, the tool embeds five traditional weaving techniques, 39 weaves and six types of yarns, which have been defined thanks to close collaboration of experts in computer graphics, art history and historical fabrics. Additionally, users can change the color of yarns and produce different 3D representations for a given fabric, which are interactive in real time. In this paper, we bring the details of the design and implementation of this tool, focusing on the input data, the strategy to process images, the 3D modelling of yarns, the definition of weaves and weaving techniques and the graphical user interface. In the results section, we show some examples of image analysis in order to subtract the design of historical fabrics, and then we provide 3D representations for all the considered weaving techniques, combining different types of yarns.

This paper reviews the existing predictive models concerning insects and mites harmful to grapevine. A brief conceptual description is given on the definition of a model and about different types of models: deterministic vs. stochastics, continuous vs. discrete, analytical vs. computer-based, and descriptive vs. data-driven. The main biological aspects of grapevine pests covered by different types of models are phenology, population growth and dynamics, species distribution, and invasion risk. A particular emphasis is put on forecasting epidemics of plant disease agents transmitted by insects with sucking-piercing mouthparts. The most investigated species or groups are the glassy-winged sharpshooter Homalodisca vitripennis (Germar) and other vectors of Xylella fastidiosa subsp. fastidiosa, a bacterium agent of Pierce’s disease; the European grape berry moth, Lobesia botrana (Denis and Schiffermuller); and the leafhopper Scaphoideus titanus Ball, the main vector of phytoplasmas agents of Flavescence dorée. Finally, the present and future of decision-support systems (DSS) in viticulture is discussed.

Plato's Sophist begins with an attempt to arrive by division at a definition of a Sophist. In the course of the attempt six different descriptions are discussed and the results summarized at 231 c-e. A seventh and final account may be said to occupy the whole of the rest of the dialogue, including the long digression on negative statements. The first five divisions characterize with a considerable amount of satire different types of sophist, or more probably different aspects of the sophistic art. The sixth division (226 a–231 b) is very different. To quote Cornford's words, ‘satire is dropped. The tone is serious and sympathetic, towards the close it becomes eloquent’.

The relevance of improving the quality of preventive medical surveillance of children and adolescents is undeniable, which provides the basis for the search for methodologically sound approaches to an integrated assessment of the health of the child population. The purpose of the study was to develop and create the software product «Computer Program «Comprehensive Assessment of the Health of Children and Adolescents». For realization of the purpose, patent search, compilation of a technical specification on the basis of criteria of assessment of children’s health and assignment to a particular group of health, writing of a software product using modern programming libraries, as well as preparation of accompanying documents for registration of an intellectual property object were performed. The result of the work was the «Computer Program «Comprehensive Assessment of the Health of Children and Adolescents», designed for the integrated assessment of the state of health of children and adolescents during screening and preventive examinations. After filling in all fields, the program processes the received data and displays the final result — assessment of the child’s health status with the definition of the health group. Information about the examined patient is sent to the program database. The built-in database allows you to systematize the data obtained, analyze the health indicators of the surveyed contingents both in one-step and in longitudinal studies. This program product can be used in the work of medical organizations, higher educational institutions of a medical profile, physical education organizations and institutions of the Federal Service for Supervision of Consumer Rights Protection and Human Welfare in the Russian Federation.

ABSTRACT The intra-parasequence scale is still relatively unexplored territory in high-resolution sequence stratigraphy. The analysis of internal genetic units of parasequences has commonly been simplified to the definition of bedsets. Such simplification is insufficient to cover the complexity involved in the building of individual parasequences. Different types of intra-parasequence units have been previously identified and characterized in successive wave-dominated shoreface–shelf parasequences in the Lower Cretaceous Pilmatué Member of the Agrio Formation in central Neuquén Basin. Sedimentary and stratigraphic attributes such as the number of intra-parasequence units, their thickness, the proportions of facies associations in the regressive interval, the lateral extent of bounding surfaces, the degree of deepening recorded across these boundaries, and the type and lateral extent of associated transgressive deposits are quantitatively analyzed in this paper. Based on the analysis of these quantified attributes, three different scales of genetic units in parasequences are identified. 1) Bedset complexes are 10–40 m thick, basin to upper-shoreface successions, bounded by 5 to 16 km-long surfaces with a degree of deepening of one to three facies belts. These stratigraphic units represent the highest hierarchy of intra-parasequence stratigraphic units, and the vertical stacking of two or three of them typically forms an individual parasequence. 2) Bedsets are 2–20 m thick, offshore to upper-shoreface successions, bounded by up to 10 km long surfaces with a degree of deepening of zero to one facies belt. Two or three bedsets stack vertically build a bedset complex. 3) Sub-bedsets are 0.5–5 m thick, offshore transition to upper-shoreface successions, bounded by 0.5 to 2 km long surfaces with a degree of deepening of zero to one facies belt. Two or three sub-bedsets commonly stack to form bedsets. The proposed methodology indicates that the combination of thickness with the proportion of facies associations in the regressive interval of stratigraphic units can be used to discriminate between bedsets and sub-bedsets, whereas for higher ranks (bedsets and bedset complexes) the degree of deepening, lateral extent of bounding surfaces, and the characteristics of associated shell-bed deposits become more effective. Finally, the results for the Pilmatué Member are compared with other ancient and Holocene examples to improve understanding of the high-frequency evolution of wave-dominated shoreface–shelf systems.

The choice of the article’s topic is conditioned by the necessity to develop happiness management (such as knowledge management, time management, etc.). With considerable attention to the definition of “happiness”, the analysis of recent publications reveals that it is crucial to understand the deep foundations of happiness, create a typology, reveal the basic principles of different types of understanding of happiness, which was chosen as the topic research. Theoretical approaches to the definition of “happiness” are chosen sociology of imagination of G. Durand, the theory of archetypes of C. Jung, and the theory of images and dreams of G. Bachelard. In the context of this system of views, the idea of happiness is the result of a free play of the imagination, which, while being on the path from past to future, is transformed, revealed, comes accurate as a result of previous collective and individual intermediate ideas, and is enriched and concretised by individual people, social groups, individuals. The mythos of happiness across nations and people differs in the way, method, and tools of individuation, the discovery of the Self. The anthropological tract of happiness has an end to its existence. It is determined by the cessation of existence, the life of nations and individuals. The desire to experience pleasure (according to Freud), the desire to rise (according to Durand) are reflexive, which determines the physiological basis of happiness. Representations of happiness determine priorities, coordinate the direction of thinking, actions, reactions to external circumstances, and choose ways to achieve happiness. This is done through the transcendental function (according to Jung) – a psychological function that arises from the connection of the content of the unconscious with the content of consciousness. Achieving happiness allows one to strengthen the subjectivity and reveal their uniqueness, which allows them to identify typological features (archetypes) of behavioural reactions of people based on individual and group ideas about happiness. The authors reveal the basic foundations of such archetypes of happiness as hedonism, eudemonia, “rat racing”, nihilism, subjective well-being.

The article gives an analysis of problems of formation of skills in children of the senior preschool age to build stories of different types. On the basis of the theoretical analysis of psycho-pedagogical and special literature, based on the main definition of «building a story», a subordinate term is formulated in relation to the topic of the study: «building stories of different types» The psychological and pedagogical conditions of formation of sustainable skills of creation and expedient use of stories of different types in children of the senior preschool age are revealed and substantiated. The components, criteria, indicators and levels of formation of abilities to build a different type of narration in children of the sixth year of life are determined. The stages of formation of persistent skills for building different types of stories by senior preschoolers are singled out. The lack of effective pedagogical technologies in relation to the formation of skills in the children of the senior preschool age to build and expedient use of narration of comprehensive typing significantly reduces the effective preparation of children to school. The proposed pedagogical and motivational technology for the formation of children of the sixth year of a sustainable ability to create stories of various types provides the small person an effective communicative tool, which will definitely promote its self-realization both in school environment and in career, society, own life. The prospects for further research are outlined, such independent types of stories are presented as a story - an instruction and a story - a presentation.
