Abstract The expressions tack, tackiness, and stickiness have been in use since the beginning of the rubber industry. During the years their meaning has changed considerably. The first occasion where tackiness was mentioned was in the case of crude natural rubber. The surface of the rubber became tacky or sticky during storage. This phenomenon has been thoroughly discussed in the literature. As a general conclusion it was accepted that both oxidation and depolymerisation occurred. Three factors were reported to be the cause of these processes: light, traces of copper, and manganese. From our point of view we would call this effect stickiness, as we are only interested in the building tack of rubber. In the period when the only rubber was natural rubber and high loadings of highly active fillers were not generally used in compounds, building tack was no problem. Building tack was first mentioned in a publication by Griffith and Jones in 1928. They started their experiments by measuring tack in their search for methods to prevent cotton liners from sticking to unvulcanized rubber. One would have expected much work on the measurement and improvement of tack in Germany and Russia during the development of synthetic rubbers. However, this only proved to be the case in Russia. The first publication available was the translation of an article by Voyutskii and Margolina in 1957. From Voyutskii's work we were able to trace the first article in 1935 by Zhukov and Talmud, who studied the adhesive power of synthetic rubber. In the USA the first theoretical approach to the subject was by Josefowitz and Mark in 1942, who at that time did not realize the difference between stickiness and tack. This difference became clear when lack of tack became the big problem in the use of synthetic rubber. In many cases it was found that addition of resins and softeners gave a very sticky compound which had no building tack at all. The tack problem was first discussed at the ASTM symposium on the application of synthetic rubbers in 1944 by Juve who gave a definition of building tack. From that time, the problem has been studied regularly, especially from the practical side, to find ways and means to improve the building tack of synthetic rubbers.

Abstract X-RAY STRUCTURE OF SYNTHETIC RUBBER In presenting a series of x-ray diagrams of various types of synthetic rubber in comparison with natural rubber, in both the stretched and the unstretched condition, it is our purpose to bring out the fact that the molecular structure of synthetic rubbers is entirely different from that of natural rubber. It is proposed also to review briefly the theories which have been advanced, based on the x-ray analysis of rubber, to account for the elasticity of natural rubber, and to advance the possible reason for the difference shown by the x-ray diagrams of synthetic rubber. At the present time, from the most general point of view, the molecular structure of a rubberlike material is envisaged as a sort of brush-heap structure of entangled long chain molecules. x-Ray diffraction patterns show that, for some rubberlike materials, notable regularities of structure sometimes occur in the tangle of long-chain molecules. It is now realized that these regularities are not essential for rubberlike behavior. Nevertheless their observation and study is important because they afford a unique opportunity for studying the molecular structure of the chains and the molecular rearrangements which occur with the application of stress.

Authors in this contribution focus on issue of subject matter structure creation by the teacher as an important psycho-didactic domain of education process and how does a student perceive this structure. The aim of the teacher is not only to impart the knowledge to students but also to show them and teach them possible ways of how to understand the subject matter better and how to get to the fundamentals of it. Based on the structure of subject matter created by the teacher a student creates cognitive frames which become basis for his further learning. We pay attention to definition of epistemology of subject matter structure, questions of psycho-didactic approach to teaching, creating structure of subject matter and how does the teacher work with the text. Empirical part of the contribution investigates teachers' preferences of subject matter structure and statistically describes subjective perception of level of understanding of the subject matter by a student influenced by the particular subject matter structure realized by the teacher.

The article is devoted to the definition of concept in modern linguistics. Various points of view and definitions of the basic concepts are considered: "concept", "conceptual sphere", "content". The aim of the article is to describe and explain such a complex unit as a concept from the point of view of linguistics. The object of research is studied in its various manifestations, the combination of verbal and nonverbal means of information expression in the conceptual sphere is revealed. the relevance of this topic is due to the need for a detailed consideration of the concept of concept based on the works of prominent scientists and linguists. Researchers treat the concept as a cognitive, psycholinguistic, linguocultural, cultural and linguistic phenomenon. The concept is an umbrella term because it "covers" the subject areas of several scientific fields: primarily cognitive psychology and cognitive linguistics.

The Russian Language

The article considers and analyzes various opinions on the category "forensic study of personality". From the point of view of the Russian language, the various meanings of the term "study" fully and in a multifaceted way reflect the activities of the investigator in the study of the person in the course of sufficient disclosure and investigation of crimes. It is concluded that forensic study of personality can be considered as a process, theory (doctrine) and part of criminalistics (educational discipline, special course). In this connection, the definition of the term "forensic study of personality" depends on understanding of its essence. Forensic study of personality as a process for the study of personality is associated with activity. Forensic study of the personality as a theory (doctrine) is associated with the objective laws that constitute the subject of criminalistics. Forensic study of the personality as a section of criminalistics (academic discipline, special course) is based on a theoretical basis, on the basis of which methods, approaches to studying personality are considered. The ultimate goal of forensic study of personality is solving the problems of disclosure and investigation of crimes. Author's definitions of the term "forensic study of personality" are proposed.

The article deals with scientific and theoretical understanding and the provision of the definition of the category "actors of administrative and legal support of information security in the customs area". The author has disclosed and analyzed the provisions of the administrative and legal doctrine of the above questio, besides, the problematic issues of the definition of "subjects of administrative and legal support of information security in the customs sphere" are identified, andthe necessity of distinguishing this concept from other related concepts and categories is defined. Disclosing issues of actors of administrative and legal support of information security in the cus-toms sphere, it is necessary to avoid substitution of concepts and clearly understand the difference between the concepts of "institutional mechanism of administrative and legal support of information security in customs" and "state mechanism of administrative and legal support of information security in the customs sphere "from the concept of" subjects of administrative and legal support of information security in the customs sphere ". After all, the concept that is the subject of our study, of all the above, has the most comprehensive and broad scope and meaning. That is why, disclosing a set of subjects of administrative and legal support of information security in the customs sphere, it is advisable to apply a broad approach to understanding this category, given that among such subjects must be considered non-state subjects. objects - local governments, public organizations, etc. Because without their activities such a list will not be complete, and the mechanism of administrative and legal support of information security in the customs sphere will not be such that covers all possible spheres of public life and methods of information security. The current general information and administrative legislation, as well as special legislation gov-erning the procedure of customs, is considered in order to more clearly disclose the features and legal status of the actors of administrative and legal support of information security in the customs area. Each of these entities plays an appropriate role and occupies the necessary place in the system of national security of Ukraine, information security of Ukraine in general and information security in the customs area in particular. This role can be described as the implementation of general control over information security in the customs area, as well as taking measures to respond to violations of information legislation and the emergence of threats to information in the customs area within the powers defined by law. At the same time, the administrative and legal provision of information security is carried out directly by the customs authorities.

The study puts forward the thesis that the basis for the allocation of structural subdivisions of civil procedural law is mainly the subject of legal regulation. The complex internal structure of the system of this branch of law is due primarily to the diversity of civil procedural relations that constitute the subject of regulation of this branch of law. The work reveals the essential features of the concept of “system of civil procedural law”, defines the grounds for its structural subdivisions and their composition, gives the definition of this category. In particular, the author has formulated the idea that the system of civil procedural law is an internally coordinated set of civil procedural rules, institutions and other relatively independent structural subdivisions of this branch of law, naturally interconnected into a single whole due to the unity of civil procedural relations. Also in this study the point of view is expressed that each level of the system, as well as the entire system of civil procedural law as a whole, is characterized not only by typical features of its constituent elements, but also by their typical, regular relationships that constitute its structure.

In this paper, I explain the problem of the dreamer in the Zhuangzi. I aim to show that no difference exists between dreaming states and waking states because we have a fluctual relationship with these two stages. In both, “we are dreaming.” Put another way, from a psychoanalytical point of view, one stage penetrates the other and vice versa. The difference between dreaming and non-dreaming disappears because dreaming is a structural process. Also, from a psychoanalytical perspective, all confirmations and negations about dreams and non-dreams leads to one point: the being, or rather the becoming, of the subject. How does this solve the problem of the True Person/True Human Being (zhenren真人)? Does such a person have dreams or not? Does the True Person sleep without dreams, as we find in the Zhuangzi? From a psychoanalytic perspective, this is not possible. To prove this, I will present few passages from the Zhuangzi and offer a psychoanalytic explanation of them based on Jacques Lacan’s theory of the fantasy and desire.

It is increasingly realized that hypnosis may be seen from an interpersonal point of view, meaning that it forms part of the relationship between the hypnotist and the subject. From this premise it follows that what goes on in the relationship prior to hypnosis probably has an influence on the hypnosis. Certain of these prior occurences can then be seen as waking suggestionns (however implicitly given) that the subject should behave in a certain way with regard to the subsequent hypnosis. A study was conducted to test the hypothesis that waking suggestions regarding post-hypnotic amnesia are effective. Eighteen female subjects were randomly divided into two groups. The groups listened to a tape-recorded talk on hypnosis in which for the one group amnesia for the subsequent hypnotic experience and for the other group no such amnesia was suggested. Thereafter the Stanford Hypnotic Susceptibility Scale was administered to all subjects. Only the interrogation part of the amnesia item of the scale was administered. The subjects to whom post-hypnotic amnesia was suggested tended to score lower on the amnesia item than the other subjects, as was expected, but the difference between the mean amnesia scores of the two groups was not significant.

Difficulties in describing such notions as vernacular, common slang and slang and the reference of certain lexical units or texts to a particular language phenomenon stem from the variety of opinions and ways of defining each of them. These debatable questions have become more distinctive in Russian linguistics with the growing contacts with European linguistic schools and therefore copying the terms without adapting them to Russian theory of language. The using of these terms is becoming chaotic due to the fact that modern Russian linguistics often neglects the basic achievements of Soviet linguistics in the field of distinguishing language varieties. The article considers two approaches to the definition of vernacular, common slang and slang: from the point of view of their being fully functional language varieties and from the point of view of their functional facilities. As a result of the analysis of the data about language varieties, a conclusion is drawn about the common and different in these concepts. If these notions considered as similar to major language varieties such as standard language, standard colloquial speech and territorial dialects, then they cannot be called fully functional language varieties, since they have an extremely vague social base, they are characterized by a low degree of standardization, functional diversity and the intersection of their lexical content. Thus, it can be concluded that such language phenomena belong to the specific kind of language variations that are defined by their transitional nature. If functional facility of vernacular, common slang and slang is considered, it is worth noting that there are a lot of stylistically marked lexical units in slang. They are slightly less numerous in vernacular, and even less numerous in common slang. This peculiarity stems from the fact that common slang includes lexical units able to function as the fillers of the gaps in standard language, standard colloquial speech or territorial dialects. It should be noted that the lexical units of all three language phenomena are used in various communication situations even by the people who are well versed in the norms of the standard language. The fact that lexical units belong to vernacular, common slang or slang does not prevent well-educated speakers from using all stylistic functions of such units. Speakers who know the difference between standard and slang or vernacular words are able to vary these language tools to attract the attention of a certain category of people (for example, for advertising, communicating with youth, etc.).
