The deterioration of environmental factors, economic and technological development, the formation of complexity in societies, the rise of complex structures have made the environment and green management practices more important. Especially value-creating green approaches are considered as critical components in both public and private sector applications and defined as indicators of success in terms of sustainability. On the other hand, green marketing strategies are also important practices that have a positive impact on the environment and should be carefully emphasized for the inheritance of nature to future generations. Recently, it has been on the agenda quite a lot and it is understood for all sectors.In this study, it is aimed to determine the criteria for value-creating green approach practices in logistics companies operating in the TR A1 region due to the above mentioned importance and to choose the most ideal green marketing strategy. In solving this problem, Multi Criteria Decision Making (MCDM) methods, which are a complex decision-making method, have been used. According to the results of the research, it was determined that the most important criterion in value creating green approach applications as Environmental Focused Strategic Decisions (C3), and the least important criterion as Environmental Life Cycle Analysis (C2). It has been determined that the most ideal green marketing strategy is Green Innovation (A1). Accordingly the importance of the environmental based strategic decisions is revealed in terms of creating green marketing strategy for companies.

Authors: Fan Ningsong , Jenkins Richard , Yu Pengfei , Lupoi Rocco , Yin Shuo , Cizek Jan
Published: September 2021

In this study, a novel strategy to manufacture high strength cold-sprayed Al coating by using powder with wide size distribution is proposed. The microstructure and mechanical properties of deposited coating sprayed at three typical impact velocities before and after heat treatment are investigated. Furthermore, the deposition and strengthening mechanisms of the coating sprayed at various impact velocities are clarified. The results show that the coating with higher density and mechanical properties can be successfully fabricated by cold spray at comparatively low particle impact velocity. The mechanical properties were enhanced with the contribution of heat treatment process. It is the in-process tamping effect induced by larger powder that results in the severe plastic deformation thus leads to densification and excellent mechanical properties of the cold-sprayed Al coating.
Study of the Effect of Thickness on the Residual Stress Profile of a Cold Spray Coating by Finite Element Analysis
Authors: Torres Felipe , Fernandez Ruben
Published: September 2021

The understanding of residual stress is of critical importance in the cold spray and thermal spray processes. It has a direct effect on the integrity of the coating related to the adhesion strength, fatigue life, and can lead to undesired effects such as the delamination of the coating. In cold spray, several investigations have evaluated the impact of the residual stress on the coatings, and it is generally accepted that cold spray coatings follow a similar profile to those obtained in the shot peening process. Although the measurement of residual stresses gives fundamental insight into the process, the estimation of such stresses considering the deposition of each layer by numerical methods has not been extensively studied. This work proposes a method for analyzing the evolution of residual stress on a cold spray coating, both on the coating and the substrate, as a function of the deposited layers, using Finite Element Analysis (FEA). The evolution of the residual stress profile with the coating thickness was obtained along the transverse direction. The results were compared to experimental and numerical data from previous studies. The influence of the deposition of each layer on the residual stress profile has been discussed.

Authors: Kaiping Du , Shengfeng Li , Jie Shen , Ziqiang Pi , Xing Chen
Published: September 2021

The product quality of selective laser melting (SLM) is closely related to the alloy powder characteristics, including the size distribution and the oxygen content. In this work, the 316L stainless steel powder was prepared by a vacuum atomization furnace and sieved into a normal-sized distribution range from 15 to 53 μm with a median diameter of 37.4 μm, and a fine-sized distribution range from 10 to 38 μm with a median diameter of 18.9 μm. Then they were mixed with each other in different proportions. The results show that, under the condition of the same SLM parameters, the SLM part, with adding a large amount of fine-sized powder, has a lower density and strength, as well as more holes and spheroidized particles, compared with the SLM part with adding a small amount of finer-sized powder. Furthermore, the 316L stainless steel powder with a high oxygen content was prepared by a non-vacuum atomization furnace. Although the 316L stainless steel powder with a high oxygen content can be evenly spread in the SLM process, the surface layer of the powder is easy to form an oxide film during the cooling and solidification of powder inside the molten pool. Under the action of thermal stress, the small crack forms and expands along the oxide film, eventually leading to large cracks inside the melt channel.

A composição, dinâmica e longevidade do banco de semente do solo é variável em função do sistema de manejo, condições climáticas e espécies de plantas daninhas presentes. Desse modo, objetivou-se quantificar o banco de semente de plantas daninhas do solo sob diferentes sistemas de manejo do solo. O experimento foi realizado em área de cerrado, no campo experimental da Embrapa e posteriormente em casa da vegetação do curso de Agronomia da Universidade Federal de Roraima, em Boa Vista-RR. Foi utilizado delineamento inteiramente casualizado em esquema fatorial 5x4x2 com quatro repetições. Os tratamentos consistiram do uso associado entre cinco diferentes sistemas de manejo do solo (vegetação nativa, cultivo mínimo, sistema plantio direto, sistema convencional e sistema convencional com rotação de cultura), quatro profundidades de solo (0-5; 5-10; 10-15 e 15-20) cm e duas amostras de solo (indeformada e deformada). O sistema plantio direto mostrou-se eficiente no controle de plantas daninhas, pois o número de germinantes foi inferior ao observado no sistema convencional, convencional com rotação e vegetação nativa. O maior número de germinantes são encontradas nas amostras deformadas e nas profundidades 0-5 e 5-10 cm do solo.
Stigma towards Patients with Chronic Obstructive Pulmonary Disease: To Help or To Judge?
Authors: Khan Iqbal
Published: September 2021

Chronic Obstructive Pulmonary Disease (COPD), the third leading cause of mortality worldwide, is a highly incapacitating irrevocable health problem, with pulmonary and extra-pulmonary manifestations. According to Suzanne Hurd and Claude Lenfant, it is “the only chronic disease for which the finger of blame can be pointed to a single risk factor – tobacco smoking”. However, only 15-20% of smokers are afflicted. Whereas smoking is far from being the only cause, substantial proportion of COPD cases cannot be explained by smoking alone. The visibility of distressing and frightening physical manifestations of symptoms leads to serious ‘‘observable’’ consequences, such as disability or lack of control, public use of oxygen and rescue inhalers. As a result “they are disqualified from full social acceptance”. However, the stigma is not the only factor responsible for the miseries of those with COPD. In fact, there are many misconceptions in this scenario which have been discussed. The need of a huge awareness campaign for the public to improve their understanding of lung diseases (notably COPD) has been highlighted. The patient, healthcare professionals and the health services should be prepared to play their new role in the management of a chronic disease like COPD “requiring “ongoing management over a period of years or decades”. The importance of a self-management strategy has been emphasised.

Published: September 2021

Objective: It is reported that age and sex have been identified as potential risk factors for severe outcomes and the distribution of coronavirus disease (COVID-19), although the specifics of these relationships are unclear. Furthermore, little is known about the relationship between age, sex, COVID-19, and population density in Thailand. This study proposed to examine the relationships among age, sex, population density, and the number of COVID-19 patients in Thailand.Material and Methods: In this nationwide descriptive correlational study, the dataset of daily COVID-19 cases in Thailand between January 12, 2020, and November 30, 2020, and population density (people/km2 ) in each province of Thailand was retrieved from the Open Government Data of Thailand, the Registration Office Department of the Interior, the Ministry of the Interior, and the National Statistical Office of Thailand. Chi-square and Pearson product-moment correlation were used to determine the difference and relationships among studied variables. Simple linear regression was used to predict the number of COVID-19 cases based on population density.Results: The findings illustrated a significant difference between male and female patients, in which the number of male patients was higher than female patients across age groups 31-45 years, 40-60 years, and >60 years (p-value<0.010). Further, population density was significantly associated with the number of COVID-19 cases.Conclusion: This investigation would provide intervention planning implications during potential future pandemics, especially in groups at higher risk (males, age 17-46 years old, and people living in high-density population areas).
Lysophosphatidylcholine 16:0, a Promising Biomarker for Severe Fibromyalgia
Authors: Delage A.
Published: September 2021

Fibromyalgia (FM) is a complex disease without any clear physiopathology, thus treating FM remains challenging for physicians. In this article Hung et al. propose a new mouse model of FM in which adult mice are exposed to repeated and intermittent sound stress (RISS). These stressors are shown to have an effect at the cellular level: leucocytes generate a high amount of reactive oxygen species (ROS), which triggers plasma lipid peroxidation and an excessive production of lysophosphatidylcholine (LPC) 16:0. LPC16:0 molecules then activate acid-sensing ion channel 3 (ASIC3) on muscle nociceptors, generating a central sensitization process responsible for the development of FM-like phenotypes (hyperalgesia, chronic fatigue, and anxiety). In the second part, a clinical investigation was performed on patients suffering from mild and severe FM. During the month preceding the study, FM patients perceived more daily stressors than healthy controls (HC). In severe FM patients, LPC16:0 levels are correlated with ongoing pain severity. This study suggests that LPC16:0 could be a biomarker for FM, particularly in its severe forms, and proposes to further investigate the effects of platelet-activating factor acetylhydrolase (PAF-AH) inhibitors such as darapladib on fibromyalgia. These molecules could prove to be interesting therapeutic compounds for the treatment of severe FM.
Afterword

Published: September 2021

The sensory turn and the affective turn in contemporary scholarship both crystalised at roughly the same time but then diverged. This special issue reintegrates them. Conjointly, these twin approaches direct attention to the multiplicity, agency, and interactivity of the full spectrum of human faculties (i.e., how the senses and affects intersect with and may also disrupt the rule of reason) in addition to highlighting the extent to which ‘the perceptual is political.’ The resulting paradigm has precipitated a shift from the study of communities as ‘imagined’ to how they are sensed and/or felt, and from a focus on ‘the human condition’ to the intensive investigation of the multiple ‘national post-revolutionary conditions’ that define the current conjuncture. By foregrounding the aesthetics of politics, and tracking the eruption of dis-sensus (laughter, graffiti, dissent) within the con-sensus that states seek to foster in their citizenry, this special issue sounds a much-needed wake-up call.
Fallstudien zur Kooperation an Ganztagsschulen: Die Schulmensa als bedeutender Nebenschauplatz der multiprofessionellen Kooperation?
Authors: Reinert Martin , Gaiser Johanna M.
Published: September 2021

Im Ganztagsschuldiskurs gelten fest in den Tag verankerte Kooperationszeiten und -orte als wichtige Stellschrauben für die Entwicklung der multiprofessionellen Kooperation. Mit der Implementierung dieser Schnittstellen geht die Hoffnung auf eine strukturell abgesicherte Form der Kooperation und einen verbesserten Dialog über Schülerinnen und Schüler einher. Im vorliegenden Beitrag wird die Annahme vertreten, dass durch das Fokussieren dieser ‚festen‘ Zeiten und Orte der Gelegenheitscharakter der Kooperation und damit der Blick auf bedeutsame Nebenschauplätze bisher nur randständig betrachtet wird. Am Beispiel der Schulmensa wird in zwei explorativen Fallstudien aufgezeigt, dass diese als fluide Schnittstelle im Alltag genutzt wird und ihr vor dem Hintergrund struktureller Herausforderungen der Kooperation eine kompensatorische Funktion zukommt. Zudem wird herausgearbeitet, dass mit dem Hinzufügen von Kooperationsanlässen zugleich die Gefahr einer Überfrachtung des Settings einhergeht.
Institutionelle Erwartungen als Rahmen multiprofessioneller Kooperations- und Vernetzungsstrukturen von Familienzentren. Handlungslogiken organisationaler Akteur*innen
Authors: Schilling Carina
Published: September 2021

Eine zentrale Erwartung an Familienzentren ist die Familienorientierung und diese geht mit der Aufforderung zu multiprofessioneller Kooperation und Vernetzung einher. Im Zentrum dieses Beitrags steht die Frage, wie Familienzentren ihre multiprofessionellen Kooperations- und Vernetzungsstrukturen angesichts dieser Erwartung gestalten. Das Phänomen wird dabei aus der Perspektive des Neo-Institutionalismus betrachtet und als Übersetzungsprozess verstanden: Anhand zweier exemplarischer Fälle wird aufgezeigt, dass Familienzentren ihr Handeln an dieser Erwartung ausrichten. Dabei werden allerdings Anpassungen sichtbar, welche aus den Handlungslogiken organisationaler Akteur*innen angesichts vielfältiger institutioneller Erwartungen resultieren. Durch die Übersetzungen zeigen sich zwei unterschiedliche Formen der Familienorientierung und Konstrukte von Multiprofessionalität. Das organisationale Handeln im Kontext multiprofessioneller Kooperation und Vernetzung stellt somit ein vielschichtiges Phänomen dar, welches durch unterschiedliche institutionelle Erwartungen an das organisationale Feld der Familienzentren gerahmt wird. Gleiches gilt für die Kooperations- und Vernetzungsstrukturen.

Gewalthandlungen unter Alkoholeinfluss stellen ein Phänomen dar, das häufig bei Jugendlichen auftritt. Der Beitrag nimmt daher die Frage nach der Rolle des Alkohols in Gewaltsituationen aus Sicht Jugendlicher in den Blick. Mit Hilfe der Interaktionsritualtheorie (Collins, 2004) wird in einem Situationsansatz die Dynamik der Gewalt zweier ausgewählter empirischer Beispiele nachgezeichnet. Anhand der Beschreibungen, welche die delinquenten Jugendlichen zu ihrer emotionalen Ausgangslage geben, wird der Einfluss von Alkoholkonsum während der Gewalttat analysiert. Die Interviewdaten sind mittels problemzentrierter Interviews gewonnen und sequenzanalytisch ausgewertet worden.
Drosophila as a Model for Microbiota Studies of Neurodegeneration
Authors: Kitani-Morii Fukiko , Friedland Robert P. , Yoshida Hideki , Mizuno Toshiki
Published: September 2021

Accumulating evidence show that the gut microbiota is deeply involved not only in host nutrient metabolism but also in immune function, endocrine regulation, and chronic disease. In neurodegenerative conditions such as Alzheimer’s disease (AD), Parkinson’s disease (PD), and amyotrophic lateral sclerosis, the gut-brain axis, the bidirectional interaction between the brain and the gut, provides new route of pathological spread and potential therapeutic targets. Although studies of gut microbiota have been conducted mainly in mice, mammalian gut microbiota is highly diverse, complex, and sensitive to environmental changes. Drosophila melanogaster, a fruit fly, has many advantages as a laboratory animal: short life cycle, numerous and genetically homogenous offspring, less ethical concerns, availability of many genetic models, and low maintenance costs. Drosophila has a simpler gut microbiota than mammals and can be made to remain sterile or to have standardized gut microbiota by simple established methods. Research on the microbiota of Drosophila has revealed new molecules that regulate the brain-gut axis, and it has been shown that dysbiosis of the fly microbiota worsens lifespan, motor function, and neurodegeneration in AD and PD models. The results shown in fly studies represents a fundamental part of the immune and proteomic process involving gut-microbiota interactions that are highly conserved. Even though the fly’s gut microbiota are not simple mimics of humans, flies are a valuable system to learn the molecular mechanisms of how the gut microbiota affect host health and behavior.
Single node repair algorithm for a multimedia cloud storage system based on network coding
Authors: Niu Xin , Jiang Jingjing
Published: September 2021

Multimedia is inconvenient to use, difficult to maintain, and redundant in data storage. In order to solve the above problems and apply cloud storage to the integration of university teaching resources, this paper designs a virtualized cloud storage platform for university multimedia classrooms. The platform has many advantages, such as reducing the initial investment in multimedia classrooms, simplifying management tasks, making maximum use of actual resources and easy access to resources. Experiments and analysis show the feasibility and effectiveness of the platform. Aiming at the problems of the single-node repair algorithm of the existing multimedia cloud storage system, the limited domain is large, the codec complexity is high, the disk I/O (Input/Output) cost is high, the storage overhead and the repair bandwidth are unbalanced, and a network coding-based approach is proposed. Multimedia cloud storage. System single node repair algorithm. The algorithm stores the grouped multimedia file data in groups in the system, and performs XOR (exclusive OR) on the data in the group on the GF(2) finite field. When some nodes fail, the new node only needs to be connected. Two to three non-faulty nodes in the same group can accurately repair the data in the failed node. Theoretical analysis and simulation results show that the algorithm can reduce the complexity and repair of the codec, and reduce the disk I/O overhead. In this case, the storage cost of the algorithm is consistent with the storage cost based on the minimum storage regeneration code algorithm, and the repair bandwidth cost is close to the minimum bandwidth regeneration code algorithm.

Authors: Kumar Manish , Kumar Bhavnesh , Rani Asha
Published: September 2021

The primary objective of this work is to optimize the induction motor rotor flux so that maximum efficiency is attained in the facets of parameter and load variations. The conventional approaches based on loss model are sensitive to modelling accuracy and parameter variations. The problem is further aggravated due to nonlinear motor parameters in different speed regions. Therefore, this work introduces an adaptive neuro-fuzzy inference system-based rotor flux estimator for electric vehicle. The proposed estimator is an amalgamation of fuzzy inference system and artificial neural network, in which fuzzy inference system is designed using artificial neural network. The training data for neuro-fuzzy estimator is generated offline by acquiring rotor flux for different values of torque. The conventional fuzzy logic and differential calculation methods are also developed for comparative analysis. The efficacy of developed system is established by analyzing it under varying load conditions. It is revealed from the results that suggested methodology provides an improved efficiency i.e. 94.51% in comparison to 82.68% for constant flux operation.
On 2-absorbing bipolar fuzzy ideals over LA -semigroups
Authors: Yiarayong Pairote
Published: September 2021

The aim of this manuscript is to apply bipolar fuzzy sets for dealing with several kinds of theories in LA -semigroups. To begin with, we introduce the concept of 2-absorbing (quasi-2-absorbing) bipolar fuzzy ideals and strongly 2-absorbing (quasi-strongly 2-absorbing) bipolar fuzzy ideals in LA -semigroups, and investigate several related properties. In particular, we show that a bipolar fuzzy set A = ( μ A P , μ A N ) over an LA -semigroup S is weakly 2-absorbing if and only if [ B ⊙ C ] ⊙ D ⪯ A implies B ⊙ C ⪯ A or C ⊙ D ⪯ A or B ⊙ D ⪯ A for any bipolar fuzzy sets B = ( μ B P , μ B N ) , C = ( μ C P , μ C N ) and D = ( μ D P , μ D N ) . Also, we give some characterizations of quasi-strongly 2-absorbing bipolar fuzzy ideals over an LA -semigroup S by bipolar fuzzy points. In conclusion of this paper we prove that the relationship between quasi-strongly 2-absorbing bipolar fuzzy ideals over an LA -semigroup S and quasi-2-absorbing bipolar fuzzy ideals over S.
Application of Pre-Trained Deep Learning Models for Clinical ECGs
Authors: Bender Theresa , Seidler Tim , Bengel Philipp , Sax Ulrich , Krefting Dagmar
Published: September 2021

Automatic electrocardiogram (ECG) analysis has been one of the very early use cases for computer assisted diagnosis (CAD). Most ECG devices provide some level of automatic ECG analysis. In the recent years, Deep Learning (DL) is increasingly used for this task, with the first models that claim to perform better than human physicians. In this manuscript, a pilot study is conducted to evaluate the added value of such a DL model to existing built-in analysis with respect to clinical relevance. 29 12-lead ECGs have been analyzed with a published DL model and results are compared to build-in analysis and clinical diagnosis. We could not reproduce the results of the test data exactly, presumably due to a different runtime environment. However, the errors were in the order of rounding errors and did not affect the final classification. The excellent performance in detection of left bundle branch block and atrial fibrillation that was reported in the publication could be reproduced. The DL method and the built-in method performed similarly good for the chosen cases regarding clinical relevance. While benefit of the DL method for research can be attested and usage in training can be envisioned, evaluation of added value in clinical practice would require a more comprehensive study with further and more complex cases.

Published: September 2021

About 30 million people suffer from a rare disease in Europe. Those affected face a variety of problems. These include the lack of information and difficult access to scientific knowledge for physicians. For a higher visibility of rare diseases and high-quality research, effective documentation and use of data are essential. The aim of this work is to optimize the processing, use and accessibility of data on rare diseases and thus increase the added value from existing information. While dashboards are already being used to visualize clinical data, it is unclear what requirements are prevalent for rare diseases and how these can be implemented with available development tools so that a highly accepted dashboard can be designed. For this purpose, based on an analysis of the current situation and a requirements analysis, a prototype dashboard for the visualization of up-to-date key figures on rare diseases was developed at the University Hospital Carl Gustav Carus in Dresden. The development was based on the user-centered design process in order to achieve a high-level user-friendliness. The requirements analysis identified parameters that stakeholders wanted to see, focusing primarily on statistical analyses. The dashboard handles the automated calculation of statistics as well as their preparation and provision. The evaluations showed the prototypical dashboard would be considered valuable and used by potential users. This work demonstrates that stakeholders are interested in access to prepared information and exemplifies a way to implement it. The dashboard can increase the usage of existing information in terms of a higher accessibility and thus improve the knowledge about rare diseases.

Elaboration of forecasting methods of analysis of metallurgical facilities electric drives technical state
Authors: Kozhevnikov A. V. , Brevnov N. P.
Published: September 2021

To prevent losses of equipment downtime, analytical algorithms and data of automated control systems sensors are used to estimate time to the equipment failure approach. It was shown that modern technical systems, such as automated electric drives are equipped by measuring devices which allow to accomplish self-diagnostic of the system in real time mode at existing methods of data processing and analysis. This approach is more effective than traditional methods of diagnostic and does not include additional capital expenses for specialized diagnostic equipment and personal qualification. Hypothesis of forecasting of electromechanical driving system state was elaborated and checked for continuous rolling mill runaway roller, based on character of loading modes by using only one parameter – the electric motor current. Based on the data analysis of wide strip rolling mill 2000 runaway rollers operation, normalized curves of distribution of average values of the runaway roller drive current at its normal operation and origination of a malfunction were built. It was shown that a technical system state change is fixed at appearance of a deviation of load current distribution comparing with a standard deviation. Analysis of dynamics of a statistical parameter, the standard error (the difference between actual and standard distribution) at a transition process allowed to make a forecast of roller jamming several days before the malfunction took place. The proposed approach of equipment state estimation can become a base for elaboration of a principally new methods of diagnostic of metallurgical rotor equipment.

Published: September 2021

Cutting of pipes into measured lengths on-line of pipe welding mill by disc saws and by facilities of abrasive cutting requires special measures of safety of personal. Besides, the necessity of frequent change of cutting instrument results in losses of production time. To eliminate the drawbacks, a study was initiated related to creation of shears which could enable to accomplish a quality transverse cutting of thin-walled pipes of small diameter by flat knives with various form of the working edges. A methodology and the results of study of strain-stress state of flat knives with application of physical and mathematical simulation of the process of transverse cutting of thin-walled pipes of small diameter presented. At the physical simulation using a polarization-optical installation, the pictures of deformation centers arising in the lower part of the knife in the zone of contact of its cutting edges with the body of the hollow circular profile being cut by it were obtained. In the experiment, models of three types of knives made of organic glass on a scale of 1:1 were used. Cutting edges of the knives for cutting pipes of 25 mm outer diameter, wall thickness of 2 mm were wedge-shaped, convex semicircular and concave. The data from studies of the loaded state of transparent knife models served as the basis for mathematical simulation of the strain-stress state of the shears cutting tool in the SolidWork application package using a strength analysis module that implements the finite element method in the form of tetrahedrons. The current values of the pipe cutting force used in the mathematical model were preliminarily calculated according to the previously proposed dependence, taking into account the strength of the hollow profile material and the area of the cut layer of its cross section for a given relative displacement of the cutting edges of the knife. The results of mathematical modeling were the pictures of deformations and equivalent stresses of the cutting part of the knife, determined according to the third theory of strength. A qualitative similarity has been established for the distribution patterns of stress fields recorded using the polarization-optical method on knife models and obtained in mathematical modeling for working samples of the shears cutting tool operated under the conditions of pipe welding mills. The proposed mathematical model makes it possible to estimate the values of the maximum equivalent stresses in the working part of a flat knife, taking into account the shape of its cutting edges, as well as the force required for cutting a thin-walled pipe into measured lengths with the corresponding dimensions of its cross-section and the strength of the material.

Authors: Rakhmanov S. R.
Published: September 2021

The experience of running drives of most of heavy-duty rolling mills shows that the designs of universal spindles with blade hinges under conditions of increased alternating loads are most acceptable comparing with other spindles types. Open friction surfaces are the drawbacks of these types of spindles, which complicate the matter of continuous supply of lubrication. Perfected effective system of forced lubrication of rolling mill spindles hinges proposed. The facility for their lubrication has a bearing support of balancing design, spindle, in radial holes of which spring-loaded plungers are installed in a diametrically opposite order. Besides, the facility has suction valves and force valves installed in the spindle axial holes, connecting with the radial ones. A methodology proposed to select the eccentricity of the internal cylindrical surface of the bearing support of the spindle hinge, the axis of which is located eccentrically relative the spindle rotation axis. A calculating scheme and a mathematical model of the process of lubrication supply into joints of rolling mill spindle hinge elaborated. A differential equation of lubrication motion in the conical slot of the hinge between a blade and insertions drawn up. Parameters of hydrodynamic motion of lubrication in the conical slot established. Modes of the lubrication motion in the conical slot between roller blade and hinge insertion determined. Based on experience of operation of friction couple bronze-steel, a lubrication for rolling mills universal spindles proposed. To improve the operation characteristics of hinges based on the friction couple bronze-steel, a thick lubrication having antifriction properties namely based on oils with additives ИП-10, КП-10 and ДФ-11 proposed. Dependence of pressure distribution along the length of the hinge conical slot presented for various lubrications of low viscosity (ИП-10 + ДФ-11) and high viscosity (КП-10 + ДФ-11). The quality effect of the speed of roller blade movable wall on distribution of speeds of lubrication layer motion over the height of the hinge conical slot for comparatively low and comparatively high boundary speeds demonstrated.

The relevance of the article is due to the need to clarify the historical aspect, the genesis of victimology, as well as the content of its conceptual apparatus, the formulation of hypotheses and the improvement of its scientific tools. The concept of victimization is a reflection of essential means and relationships, phenomena and processes that are directly related to crime. The problematic aspects of the relatively complex nature of the conceptual apparatus of victimology have been identified, as a result of which a large number of concepts of non-legal origin in criminology are fraught with the danger of destroying the mechanism of legal assessments and conclusions on crime, its causes, the identity of the offender and the victim, and prevention measures. Elucidation of the historical aspect, genesis of victimology, as well as the content of its conceptual apparatus, is a dynamic process of reconciling hypotheses and positions, thoughts and views of criminologists, victimologists, lawyers, sociologists and psychologists, the results of which form the doctrinal basis of victimology. The stated positions are an attempt to somewhat streamline the diversity of scientific approaches to the content of individual elements of the subject of victimology, which, in turn, forms the motivation for further discussion of representatives of domestic and foreign criminological schools. Justification of the genesis and content of the conceptual apparatus of victimology, its individual theoretical provisions is an integral part of the development of the concept of combating crime and has not only scientific, but also important practical importance. Consequently, the tasks of victimology include the study of not only those who was the victim, but also those who have never acquired the status of a direct victim of the crime. The purpose of such studies are to identify a complex of certain properties capable of imported in criminal manifestations, which allows to carry out the victimological forecast for both individual and mass levels. The study of crime victims is necessary to solve many problems, especially related to the organization of their physical protection.

The main factor in the criminalization of economic activity in the modern world in general and in Ukraine in particular, has been globalization - uncontrolled, without any rules, without the possibility of establishing fair competition. Thus, the issue of creating a separate law enforcement body to combat economic offenses has been on the agenda for many years and ended with the adoption of the Law of Ukraine “On the Bureau of Economic Security of Ukraine” on January 28, 2021. The article is devoted to the disclosure of the legal nature of a special law enforcement agency in the field of combating economic offenses, i.e. the Bureau of Economic Security of Ukraine. It is noted that the creation of a new civil service under the Ministry of Finance to replace the tax police and consolidate all powers to combat financial crimes against the state in one agency, while avoiding duplication of functions, is a priority requirement of the International Monetary Fund, which provides loans to the Ukrainian government for the development of the country's economy under the condition of successful reforms. The preconditions for the establishment of the Bureau of Economic Security in Ukraine are studied. Based on the analysis of the Law of Ukraine “On the Bureau of Economic Security”, the purpose, objectives, structure, principles of the Bureau of Economic Security of Ukraine are revealed. Attention is paid to the organizational and managerial aspects of the activities and powers of the Bureau of Economic Security of Ukraine. It is emphasized that the establishment of the Bureau of Economic Security of Ukraine will lead to more effective law enforcement activity in the formation and use of financial resources of the state and its economic security, and as a consequence, reduce shadow business in Ukraine and increase taxes and fees, optimize the structure of law enforcement, material and technical base and reduction of the total number of employees who fight crime in the field of finance.
