The known principles of active monostatic radar are based on the effect of radio wave scattering on objects located on the path of the probing signal, and the subsequent registration of a part of the wave reflected in the direction of the emitter. However, within the framework of this study, it is of interest to register objects that do not return a reflected radio echo towards the emitter. When fixing the position of an object, it is assumed that there is a possible absence of an echo signal characteristic of classical active radar with a passive response. The absence of a characteristic echo signal does not exclude its return as a result of repeated reflection inside the scene, including along other routes and from other objects. Purpose – within the framework of the implementation of technical vision in the course of tomographic observation of a complex radar scene that solves the problems of multidimensional reconstruction, a stochastic model based on the principles of tomography describing the subject area of a complex radar scene is developed. In the indicated relevance of the development of methods for radar detection of hidden objects inaccessible for registration by classical methods, a variant of using tomographic observation of a complex radar scene is proposed. In connection with the admitted lowangle and the emerging problems of an unambiguous deterministic definition, a description of the subject area of the scene from a stochastic position is proposed. In the proposed tomographic method, in conditions of limited initial data, when a deterministic approach to the reconstruction of the radar scene is not possible, an acceptable solution is sought in the stochastic description. At a given value by sampling the space, determined by the hexagonal lattice cell, the scene reconstruction is carried out by selecting and analyzing the echo signal trajectories from the possible set of proposed ones. The decision on the choice of one or another proposed trajectory and its transfer to the category of a possible solution is carried out on the basis of a preliminary calculation of the characteristics of the stochastic description.

Electron Microdiffraction

Electron microdiffraction has been used to determine the crystallography of precipitation in Al-Cu-Mg-Ag and Al-Ge alloys for individual precipitates with dimensions down to 10 nm. The crystallography has been related to the morphology of the precipitates using an analysis based on the intersection point symmetry. This analysis requires that the precipitate form be consistent with the intersection point group, defined as those point symmetry elements common to precipitate and matrix crystals when the precipitate crystal is in its observed orientation relationship with the matrix.In Al-Cu-Mg-Ag alloys with high Cu:Mg ratios and containing trace amounts of silver, a phase designated Ω readily precipitates as thin, hexagonal-shaped plates on matrix {111}α planes. Examples of these precipitates are shown in Fig. 1. The structure of this phase has been the subject of some controversy. An SAED pattern, Fig. 2, recorded from matrix and precipitates parallel to a <11l>α axis is suggestive of hexagonal symmetry and a hexagonal lattice has been proposed on the basis of such patterns.

The article analyzes the philosophical and cultural view of “doctor’s professional culture” as a result of centuries-old practice of human relations, which is characterized by constancy and passed from generation to generation. Medicine is a complex system in which an important role is played by: philosophical outlook of a doctor, philosophical culture, ecological culture, moral culture, aesthetic culture, artistic culture. We have found that within the system “doctor-patient” the degree of cultural proximity becomes a factor that influences the health or life of a patient. Thus, the following factors are important here: 1) communication that suppresses a sick person; 2) the balance of cultural and intellectual levels; 3) the cultural environment of a patient which has much more powerful impact on a patient than the medical one.At the present stage, the interdependence of professional and humanitarian training of future specialists is predominant, as a highly skilled specialist can not but become a subject of philosophizing. We outlined the sphere where the doctors present a genre variety of philosophizing (philosophical novels, apologies, dialogues, diaries, aphorisms, confessions, essays, etc.). This tradition represents the original variations in the formation of future doctor’s communicative competences, which are formed in the process of medical students’ professional training.A survey conducted among medical students made it possible to establish their professional values, which are indicators of the formation of philosophical and culturological competence. It was found out that 92% of respondents believed that a doctor should demonstrate a high level of health culture (avoid drinking and smoking habits, etc.)99% of respondents favoured a high level of personal qualities of a doctor which would allow methods and forms of medical practice to assert higher human ideals of truth, goodness and beauty that are the subject area of cultural studies and philosophy.

Introduction. The article is devoted to the problems of the essence and content of judicial ethics in the new conditions of the technical revolution and with other social needs for legal regulation. Theoretical Basis. Methods. The work used a systematic, activity-personal approach to the study of moral and ethical standards of the conduct of judges. This made it possible to reveal a new and broader view on judicial ethics, which is not simply a set of moral restrictions and obligations imposed on a judge. Results. The work has identified and analysed the signs of judicial ethics at the current stage of development. It is argued that ethical regulation is precautionary in relation to the legal regulation of the independence of judges, for they complement ethical rules and reinforce legal norms. The ethical conduct of judges is an instrument guaranteeing judicial independence in all of its manifestations, including in organisational and judicial relations. The new realities of our time recognise the expansion of boundaries and the subject area itself of ethical regulation. A broader view on judicial ethics, which differs from the traditional one, is hereby justified. The latter is defined in two ways – namely both as a system of professional values, as well as a means of judicial administration based on the principle of self-regulation. By its very nature, judicial ethics is the result (and the way) of judicial self-governance, developed on the basis of the experience of functioning bodies of the judicial community. Discussion and Conclusion. Conclusions are drawn on both the instrumental and the managerial impact of the categories of ethics. The subject of judicial ethics has been defined, which constitutes the rules of conduct of judges in the performance of their professional duties and beyond – namely the set of general principles of work of a judge, as well as the personal qualities of a judge personifying the judicial power. Proposals on the optimisation of the mechanism of ethical influence, differentiation of ethical and disciplinary norms have also been substantiated.

Achievement test is of very important assessment tool to evaluate the student’s current level of knowledge and skill acquired from classroom instruction. This test is designed to evaluate the student’s level of achievement in a particular subject for a particular class prescribed under the board or the university. In other words, to assess how much the pupils have achieved the educational objectives in teaching learning process at the end of the course and if achieved then to what extent, it has been achieved. Achievement tests are proved to be very helpful in various ways to the people who are involved in the field of education such as the teachers, the administrators, the planners, to the parents as well as for the students. The teacher very carefully develops and conduct achievement test in the class which enable the teacher to get an overall idea of the progress or the level of achievement of his students in the subject area. The teacher can determine the pupil’s strength and weakness in the subject area. So, based on this the teacher can take necessary remedial instructional strategies for the betterment of the pupil’s progress. In the same time, it also provides feedback for the teaching efficiency of the teacher.As with the time changes there have been many educational reforms taken place and in between syllabus had also been changed under different Boards of Studies. In order to maintain uniform standard of education the Government has formulated a policy to implement NCERT syllabus common to all School Boards throughout the country and accordingly the State Board of Secondary Education, Assam (SEBA) follow NCERT syllabus and to evaluate students’ achievement in terms of the policy formulated by the Board. Till now, no any standardized achievement test has been conducted for the secondary school students of Assam. Therefore, the investigators felt to construct and standardize an achievement test in the subject General Science which will definitely help in educational research.

In an ideal world, assessment should be synonymous with effective learning and reflect the intricacies of the subject area. It should also be aligned with the ideals of education: to provide equitable opportunities for all students to achieve and to allow both appropriate differentiation for varied contexts and students and comparability across various contexts and students. This challenge is made more difficult in circumstances in which the contexts are highly heterogeneous, for example in the state of Queensland, Australia. Assessment in music challenges schooling systems in unique ways because teaching and learning in music are often naturally differentiated and diverse, yet assessment often calls for standardization. While each student and teacher has individual, evolving musical pathways in life, the syllabus and the system require consistency and uniformity. The challenge, then, is to provide diverse, equitable, and quality opportunities for all children to learn and achieve to the best of their abilities. This chapter discusses the designing and implementation of large-scale curriculum as experienced in secondary schools in Queensland, Australia. The experiences detailed explore the possibilities offered through externally moderated school-based assessment. Also discussed is the centrality of system-level clarity of purpose, principles and processes, and the provision of supportive networks and mechanisms to foster autonomy for a diverse range of music educators and contexts. Implications for education systems that desire diversity, equity, and quality are discussed, and the conclusion provokes further conceptualization and action on behalf of students, teachers, and the subject area of music.

Marcus Cunliffe (1922–1990) was incontestably an important figure in American studies. In the early part of his academic career he helped to found the subject area in Britain, and he was later both awarded professorial appointments at the Universities of Manchester and Sussex and elected to the chairmanship of the British Association for American Studies, from which positions he served as a personal inspiration and professional mentor to several “generations” of UK American studies academics. Those who knew him and worked with him were invariably struck by his tall good looks, charisma and charm – characteristics that no doubt also contributed to his successful career, in Britain and in the United States, first as a visiting scholar, and later, during his final years, as the occupant of an endowed chair at George Washington University in Washington, DC. As the correspondence in his papers attest, he was held in high – and warm – regard by many of the leading US historians of his heyday. More might be said about his charm here because it also permeates his writing and persists there as a kind of afterglow, and not only for those who encountered him in person – but this essay is a critical reconsideration of his published work that, though appreciative, at least aspires towards objectivity.

Research on the role of mobile learning in computational thinking is limited, and even more so in its use in initial teacher education. Aligned to this there is a need to consider how to introduce and expose pre-service teachers to computational thinking constructs within the context of the subject area they will teach in their future classrooms. This paper outlines a quasi-experimental study to examine the role of mobile learning in facilitating computational thinking development amongst pre-service teachers in initial teacher education. The study enquires if there are significant differences in grades achieved in computational thinking and programming learning when mobile learning is introduced. Findings showed and reaffirmed the positive influence of the mobile applications on the development of computational thinking amongst the pre-service teachers who participated.

The article examines the concept and basis of responsibility in international sea freight. The relations arising in international cargo transportation by sea have a direct impact on the subject area of the institution of responsibility in this area. First of all (prima facie), the carrier and the consignor have mutual rights and obligations. However, the legal relationship between the consignee and the consignor also affects the legal relationship with the carrier, and the carrier acts as the main subject of the relevant liability. Accompanying the guilty and innocent carrier in international cargo transportation by sea is the responsibility. In both cases, the legislation of the Republic of Azerbaijan contains appropriate forms of liability. However, there is a need in the legislation of the Republic of Azerbaijan to bring absolute or objective responsibility in line with international law. In particular, the liability provisions of the legislation on sea freight must include an "institution of liability", formed in accordance with the "immunity catalog" or "exclusion catalog". In this case, the carrier is absolutely responsible for everything that does not belong to the "immunity catalog", and the problem of liability for guilt is not the subject of discussion.
