To connect rotors, to transmit and stabilize rotation motion a new class of rotary motion transmission and stabilization devices (RMTSD) was developed. They include the rings which deform axialy, radially and at an angle the radial segments, etc. with joined concentrated inertial, dissipative and elastic elements. RMTSD design schemes are copyrighted and covered by the patents of the USA, England and Germany. The classification of RMTSD development is performed according to the following characteristic features: dynamic characteristics, kind of elastically creeping elements, peculiarities of design elements, fastening, materials, etc. The classification presented gives the possibility to develop lots of constructions of new RMTSD of this type.

The article is devoted to the implementation of gamification methods in the educational process. The characteristic features of light and hard gamification are presented. The appropriateness of using gamification when applying e-learning technology is considered. Classification of courses based on hard gamification taking into account the technological features of development is proposed: courses-presentations, courses — computer games, VR/AR courses. The article also illustrates the use of various game elements of easy gamification using the example of the module “Level up! — Gamification” of the Moodle LMS. The capabilities of this module can be used in an electronic course by any teacher who has the skills of working with the Moodle.The authors present the analysis of the development of a training course in sales techniques using hard and light gamification technologies, where the course development was assessed for its complexity, manufacturability, and resource requirements. The results of the analysis showed that the development of courses using hard gamification requires much more financial and time-consuming than the development of courses using light gamification.The article evaluates the results of the educational intensiveness intense “Island 10–22”, held in July 2019 in Skolkovo, in which 100 university teams, teams of research and educational centers, teams of schoolchildren — winners of competitions, olympiads, hackathons (“Young Talents”) participated. The results of the intense confirmed the effectiveness of the use of light gamification methods in adult training. Thus, the conclusions presented in the article reveal a number of advantages that light gamification has in comparison with hard gamification.

AbstractToday, Christianity is often described as a ‘worldview’, especially among Reformed evangelicals in the USA. In this article I return to the 1890 lectures where Scottish theologian James Orr adapted the concept of Weltanschauung for Christian purposes. Although it was coined by Immanuel Kant in 1790, and primarily used in subsequent decades to theorise cultural difference and evaluate aesthetic expression, Orr nevertheless claims that the idea of a worldview is ‘as old as the dawn of reflection’ and thus appropriate to articulating Christianity. I examine Orr's engagement with the Kantian and emerging historicist context, paying particular attention to his epistemological and aesthetic citations and showing how Orr both adopts and departs from the characteristic features of the Kantian subject. I conclude by assessing the philosophical and theological costs of this project that, among other things, positions Christianity for perpetual culture war within secular societies similarly shaped by the post-Kantian subject.

The article deals with the assessment and accounting of fixed assets. Disclosed are the methodological aspects of the assessment of fixed assets when they are recognized in accounting, as well as the assessment after recognition and revaluation of these means of labor. The characteristic features of fixed assets, criteria and prerequisites for determining their useful life have been sorted out. The classification of fixed assets for accounting purposes is proposed. The methods and technical aspects of the reflection of operations based on the results of the revaluation of fixed assets on the accounts have been substantiated.

ObjectivesThe coronavirus disease 2019 (COVID-19) pandemic has prompted many initiatives to identify safe and efficacious treatments, yet little is known regarding where early efforts have focused. We aimed to characterise registered clinical trials assessing drugs or plasma treatments for COVID-19.Design, setting and participantsCross-sectional analysis of clinical trials for the treatment of COVID-19 that were registered in the USA or in countries contributing to the WHO’s International Clinical Trials Registry Platform. Relevant trial entries of drugs or plasma were downloaded on 26 March 2020, deduplicated, verified with reviews of major medical journals and WHO websites and independently analysed by two reviewers.Main outcome(s)Trial intervention, sponsorship, critical design elements and specified outcomesResultsOverall, 201 clinical trials were registered for testing the therapeutic benefits of 92 drugs or plasma, including 64 in monotherapy and 28 different combinations. Only eight (8.7%) products or combinations involved new molecular entities. The other test therapies had a wide range of prior medical uses, including as antivirals, antimalarials, immunosuppressants and oncology treatments. In 152 trials (75.7%), patients were randomised to treatment or comparator, including 55 trials with some form of blinding and 97 open-label studies. The 49 (24.4%) of trials without a randomised design included 29 single armed studies and 20 trials with some comparison group. Most trial designs featured multiple endpoints. Clinical endpoints were identified in 134 (66.7%) of trials and included COVID-19 symptoms, death, recovery, required intensive care and hospital discharge. Clinical scales were being used in 33 (16.4%) trials, most often measures of oxygenation and critical illness. Surrogate endpoints or biomarkers were studied in 88 (42.3%) of trials, primarily assays of viral load. Although the trials were initiated in more than 17 countries or regions, 100 (49.8%) were registered in China and 78 (37.8%) in the USA. Registered trials increased rapidly, with the number of registered trials doubling from 1 March to 26 March 2020.ConclusionsWhile accelerating morbidity and mortality from the COVID-19 pandemic has been paralleled by early and rapid clinical investigation, many trials lack features to optimise their scientific value. Global coordination and increased funding of high-quality research may help to maximise scientific progress in rapidly discovering safe and effective treatments.

The overall objective of this work was to develop and evaluate computer vision and machine learning technique for classification of Huanglongbing-(HLB)-infected and healthy leaves using fluorescence imaging spectroscopy. The fluorescence images were segmented using normalized graph cut, and texture features were extracted from the segmented images using cooccurrence matrix. The extracted features were used as an input into the classifier, support vector machine (SVM). The classification results were evaluated based on classification accuracies and number of false positives and false negatives. The results indicated that the SVM could classify HLB-infected leaf fluorescence intensities with up to 90% classification accuracy. Though the fluorescence intensities from leaves collected in Brazil and the USA were different, the method shows potential for detecting HLB.

This paper concerns the study of the Allee effect on the dynamical behavior of a new class of generalized logistic maps. The fundamentals of the dynamics of this 4-parameter family of one-dimensional maps are presented. A complete classification of the nature and stability of its fixed points is provided. The main results relate to the Allee effect bifurcation: a new type of bifurcation introduced for this class of unimodal maps. A necessary and sufficient condition so that the Allee fixed point is a snap-back repeller is established. In addition, in the parameters space is defined an Allee’s effect region, which determines the existence of an essential extinction for the generalized logistic maps. Local and global bifurcations of generalized logistic maps are investigated.

Criminal law institutions and basic concepts are being reformatted. This work focuses on the objective signs of theft and the mode of activity - the seizure of someone elses property. The existing law enforcement practice and the current recommendations of the Plenum of the Supreme Court of the Russian Federation on the qualification of thefts are critically perceived. The article focuses on provisions of the general theory of criminal law on the classification of theft. This study aims to substantiate the need for correlation of objective signs of theft in relation to the expansion of the boundaries of the object of theft and the method of activity. During the study, traditional methods of the sociolegal and formal-dogmatic analysis were used: documentary, comparative-legal, analytical, systemic, and logical. On the basis of the results of the study, adjustments were made to understand the objective side of theft and expand the boundaries of the method of action. The seizure of other peoples property cannot characterize the mechanism of embezzlement and reflect all aspects of qualification. The prospect of identifying theft with the extraction (receipt) of property benefits carries the risk of erasing the boundaries between embezzlement and other economic crimes. The author proposes models for the development of criminal legislation to establish criminal liability for crimes against property (property crimes). To modify the object of theft, its purpose, and mode of activity, the author proposes to identify a new group of crimes (crimes against the circulation of objects of civil rights) that would cover illegal acts against property and compulsory relations. Further scientific study requires a detailed separation of embezzlement (as attacks on bodily goods), crimes against the circulation of civil rights (as attacks on non-bodily goods), and crimes in economic activity (as attacks on the procedure for performing operations in the economy), summarizing their characteristic features and designing new formulations of crimes in the property sphere.

The article provides a theoretical analysis of the problems of scientific research dedicated to training of specialists for the economic industry. As a result of the theoretical analysis, the classification of modern researches on the problem of training of future economists has been carried out: 1) research that examines problems that are common not only for the training of future economists but also systemic problems for other specialists’ training; 2) research that analyzes the problems aimed at preparation of future economists for a certain type of activity necessary for their profession, or is related to the ways of improvement of the quality of future economists’ professional training as well as the formation of pedagogical competence among future specialists in the economic field, that is, the training of teachers of economic disciplines; 3) scientific research on comparative professional pedagogy related to training of specialists in economic specialties in other countries of the world. There has been presented the classification of scientific research related to the scientific degree for which the research was submitted: in doctoral dissertations there were raised the problems which are systemic for training of not only future economists but other specialists too. A candidate level research is more focused on individual problems of future economists’ professional training, improving the quality of professional training of future economists. It has been stressed that studies aimed at studying foreign experience of economists’ training are still not sufficient, although due attention is paid to such countries as the USA, Great Britain and Germany. The research aimed at studying the experience of the Republic of Poland, which is Ukraine’s neighbour and is close to it in culture and history, has been noted as insufficient.

The system of secrecy of documents of operative-strategic planning which worked in the armed forces of the USSR and the USA during the Cold War the author analyzes based on his experience with archival documents. On the basis of the author’s experience with work with archival documents, this article analyzes the systems of classification of operational and strategic planning documents of the Armed Forces of the USSR and the USA during the Cold War. A comparison of documents’ classification levels and works of the regime-secret (classification) bodies is made. It is determined which secrecy classification levels and additional code words were used for different documents depending on the nature of the information contained in them: nuclear planning, mobilization planning, operational plans at the theaters of war. After a detailed comparison, it is concluded that despite the widespread view of extraordinary secrecy in the USSR, in fact, the US regime-secret system was more advanced, demanding and rigid. The Soviet system included three levels of document secrecy. In addition, the US system had additional restrictions due to acronyms listing a narrow range of document users. The aim of the article is to investigate documents that reveal the preparation for war in Europe during the Cold War.
