ENGINEERING AND ECONOMIC EVALUATIONS OF VARIOUS METHODS OF JOINING CAR BODY PARTS
Abstract
New methods of joining the body units widely used in foreign automotive industry and having a number of technical advantages are not used at the Volzhsky automobile plant. Among the major reasons, usually, the application of expensive materials and equipment are named. In this regard, this paper presents the results of the aggregated estimation of a number of specific economic indicators that allow comparing the traditional and the advanced methods of joining. The authors compared the indices of labor intensity, efficiency, and capital investments per unit, as well as the production cost of one meter of joining when applying spot welding, carbon dioxide welding, flame brazing, laser welding, arc and laser brazing. The calculations were carried out separately for short and elongated joints. It is shown, that the methods of joining new for the domestic automotive industry are quite competitive economically in relation to the traditionally used methods. Taking into account technical indicators, the authors formulated the recommendations on the selection of a method of joining.
The current tendency to replace flame brazing can be explained by the high labor intensity and production cost of this method of joining. However, the replacement of flame brazing with welding in carbon dioxide is unequal, principally in terms of quality. Arc brazing is the most suitable method of body parts joining for short sections where the leak tightness, good appearance and the quality of the weld are required.
To get the elongated joinings, laser brazing is the advanced method ensuring the maximum performance and minimum production cost in comparison with all the methods of joining considered, and the specific capital investments are comparable to other methods considered.
THE STUDY OF GEOMETRY AND THE APPLICATION AREA OF CUTTING TOOL WITH Capto SHANK
Abstract
The paper covers the issue of rational application of a tool with Capto shank, as well as the conditions for clearance occurrence in the “tool – tool spindle” joint and the dependence of this clearance on the error of manufacturing a hole in the machine spindle.
The authors carried out the calculations of friction and torsion moment when drilling holes using the tool with standard Morse taper shank and Capto shank. Based on these calculations, the first technical limitation was obtained – the dependence of feed threshold ensuring the absence of drill turning in machine spindle on the tool diameter. Taking into account the maximum value of tangential stresses in the drilling tool, second technical limitation was obtained – the dependence of feed threshold on a drill diameter based on the necessary tool strength. These technical limitations were used as a principle to define the areas of rational application of standard tool shanks (Morse taper shank in particular) and Capto shank.
Using the analytic geometry method, the geometry of Capto joint was analyzed and the areas of maximum clearance occurrence in a joint were identified. At a first approximation, the cross section of a joint was displayed as the triangles with rounded corners and the joint total manufacturing error was referred to the vertex angle of a spindle hole. It allowed proving mathematically the area of maximum clearance occurrence and identifying the dependence of maximum clearance on the error of manufacturing a hole in the tool spindle.

SEMANTIC-GRAMMATICAL CHARACTERISTIC OF GATE-FORMATIONS OF THE RUSSIAN LANGUAGE
Abstract
The paper gives successively the semantic and structural characteristics of gate-formations of the Russian language on the material of “Dictionary of composites of Contemporary history” of N.V. Gabdreeva, M.T. Gurchiani and the card index of words with -gate element prepared by the author using the method of continuous sampling from All-Russia and regional newspapers, internet-sites, fiction for the period from the 70th of the XX century to the present day. The card index contains 1246 examples: the author defines their denotative sphere; describes the occurring paradigmatic relations; proves the possibility of updating vocabulary of the analyzed dictionary with the gate-formations of sport and science spheres. The author offers her opinion on the necessity of fixation of synonymic rows of political scandals’ names in the dictionary articles: Irangate – contrasgate – Irancontrasgate; Monicagate – Lewinskigate – sexgate – zippergate; Cartergate – bookgate; Reagangate – briefinggate; makes the conclusions on the belonging of words with -gate final to different groups of composites according to the degree of assimilation and cohesion of the components in the Russian language (with first assimilated component and with first unassimilated component represented by transliterated and non-transliterated forms). The author defines the stage when the foreign-language -gate structural element attains the morpheme’s characteristics of the Russian language and illustrates with the examples the functioning of -gate component as some independent lexical unit, in the result of which it attains morphological indices of number and case. The study considers gate-models of composites with assimilated first component of two stages of opening (substantiation): first stage – a model of general view: “a noun + gate”; second stage – a “specified” model (with the account of class belonging) represented by two gate-models: “a proper noun + gate” and “an appellative + gate”.
CIVIL IDENTITY OF MODERN RUSSIAN GENERATION X (ON THE EXAMPLE OF ASTRAKHAN REGION)
Abstract
One of the key characteristics of democratic and sustained development of the Russian state in modern times is the degree of population cohesion on the general civil basis. Modern Russian Generation X is represented by the citizens who were born in the Soviet Union between 1963 and 1984. Their socialization process (its main stage) concurred with such events as restructuring, disintegration of the USSR, “dashing” 1990s; today they make up a third of the population and the basis of the labor force of the country; that is why the analysis of the civil identity of Russians in this age group is so important.
The paper presents the results of a sociological survey conducted in the Astrakhan region to study the characteristics of the civil identity of the region population, in particular the representatives of Generation X. Certain levels of identity (civil, regional and ethnic) have been considered, as well as value system and orientations, patriotic feelings, and ways to implement the civil rights.
The author analyzes the conditions for the development of the Russian Generation X and the assessment of its civil identity. Data obtained as a result of research in Astrakhan region led to the conclusion of the civil identity of the studied population group, of such components of the analyzed scientific category as cognitive, evaluative, and activity; special attention is paid to the patriotic aspect.
As a part of the study of the current issue of population consolidation, as well as the further development of Russian democracy, important are the conclusions made in the paper about the overrepresentation of civil identity in Generation X, the dominance of electoral participation in the processes of civil rights implementation.
EXTERNAL LABOUR MIGRATION AS A FACTOR OF HUMAN DEVELOPMENT IN THE RUSSIAN FEDERATION
Abstract
The paper presents a comprehensive analysis of external labour migration from neighboring countries, prospects and problems of its regulation in the Russian Federation. The author emphasizes the role of migration processes in the socio-economic and socio-political life of our country, their influence on the demographic situation as a labor replenishment source, the development of production, the labor market, as well as socio-economic characteristics of the living standards. There is no doubt that compensation for the loss of working-age population only by increasing productivity, economic restructuring and engaging economically inactive population (housewives, pensioners, and disabled) onto the labor market is not possible. In this regard, it becomes apparent that in the next decade Russia will have to use foreign labor force incrementally. As the statistical analysis shows, a high concentration of migrant workers, as a rule, does not exceed the unemployment rate among the local population, as they take jobs that are not popular among the locals, and even contributes to the improvement of social and status structure of employment in the country. As for the state policy in relation to foreign migrant workers, in accordance with the Conception of the long-term socio-economic development of the Russian Federation, till 2020 its priority areas are: attracting skilled foreign specialists, creation of civilized working conditions and life of migrants in Russia, and protection of their civil rights. Thus, it becomes clear that in market economy conditions along with negative demographic processes, external labor migration is becoming one of the most important strategic factors in the development of Russia’s human potential.
DENOTATIVE FIELD FEATURE OF SEMANTICS OF INEXPRESSIBLE
Abstract
The paper defines semantics of inexpressible as the functional and semantic category, which has an independent meaning and plan of expression – the field of inexpressible; presents a brief overview of its studies in linguistics. The work proves that it is an objective-subjective meaning of the Russian language. The denotative field of semantics of inexpressible consists of constant and variable spheres. There are two constant spheres: the inner world of a man and the world beyond. It is shown that the expansion of elements of the field of inexpressible is observed in the first of the constant spheres. As a result, the overlapping of the field of inexpressible and the field of semantics of an extremely high quality of concentration takes place. The denotative sphere “inner world of a human” in the 21st century was replenished with intracorporal segment. It is shown that the elements of the second constant denotative sphere of semantics of inexpressible “world of the beyond” become less frequent and remain mostly in the language of literature. At the same time, the use of the elements of this sphere implies profanation and mimicking of initially high meanings. As for the variable spheres of the denotative area of semantics of inexpressible, the linguistic units of inexpressible correlate with various objects in broad sense, qualities and phenomena, and are applicable with respect to everything phenomenal – the sensible, and in relation to the noumenal – intelligible, but not observed. In particular, the elements of the field of inexpressible arise when one is operating rational concepts by undeveloped thinking. The element of semantics of inexpressible “to express the inexpressible” is a linguistic manifestation of the theory of the German Romantics, as the representative of the constant spheres of the language. In the Russian language in certain periods of time it became a part of the linguistic fashion in literature: Russian lyrics of the 19th century, symbolism of the early 20th century, creativity of the members of the Real Art Association, and modern Russian post-modernism. Through the example of creativity of A.S. Pushkin and M.Yu. Lermontov, the author shows that the fashion element of the artistic discourse of the 19th century “to express the inexpressible” could have been popular or unclaimed due to the individual preferences of artist in words.
SOCIAL SECURITY: ESSENCE AND SIGNIFICANCE
Abstract
The paper analyses the phenomenon of social security. Various approaches to the understanding of this term, its content and definition are considered. The author reveals and specifies the most acute problems and dangers that reduce the level of social security of Russian citizens. Special aspects contributing to the understanding of differences between the “social safety” and “social security” terms are specified and described. Basing on the study of the sources, the author determined the psychological aspect of security level understanding by different individuals and made a conclusion about the interrelation of this aspect of understanding with definite social and economic conditions of development of the individual’s region of living. The paper considers the range of issues concerned with the different understandings of determination of social security level of citizens. The author’s suggestion on the manifestation of adequate state policy in the sphere of social benefits and protection implementation as the most important direction of work of a welfare state deserves attention. The author draws the attention to the necessity of carrying out the reforms not only in the social and legal relations but also in other socially important aspects of the life of a citizen.
While carrying out the analysis of the material under the study, the author addresses the topic of inner comfort status of a person that is taken into account when determining social security in the result of social and spiritual and moral state policy aimed at the provision of normal conditions of human vital activity, his intellectual and professional fulfillment. Methods and sources used, the conclusions made and the paper’s structure and content prove the author’s innovative approach to the issues under discussion and his analytical thinking.
FUNCTIONAL CHARACTERISTICS OF MODAL PARTICLES ON THE EXAMPLE OF FIVE LANGUAGES
Abstract
The paper studies conceptual approaches to determination of the semantic nature of modal particles, as well as pragmatic actualization of particles in German, Russian, English, French and Udmurt. The goal of this work is to define functional characteristics and systematize communicative and pragmatic meanings of modal particles. The author notes that the modal particles should be examined in close connection with the speech act when a sentence that contains the particle is actualized. It is shown that modal particles are interconnected and depend on the conceptual and cognitive structure of the utterance. The paper specifies the communicative significance of modal particles which they perform in the construction of an utterance, what defines their important role in the process of language acquisition. To study and analyze the utterances with such particles, the author has used a complex of research methods aimed at identification of their communicative and pragmatic features in Russian, German, English, French, and Udmurt. Analysis of pragmatic functions of modal particles indicates that these lexical units form a subsystem of emphatic elements in the language and, therefore, are included in the system of pragmatic means of the language. The research confirms the importance and prospects for further development of this area, as currently a lot of issues associated with the use of modal particles in a variety of cognitive and pragmatic types of utterances in different languages aimed at solving communication problems remain unsolved.
SOME SEMANTIC CLASSES OF NON-OBJECT ORIENTED ACTION VERBS
Abstract
The paper studies some aspects of the verb semantics from the aspect of a nontraditional approach to researching semantics of linguistic units within morphotopical analysis. The paper analyzes the action verbs, which have the meaning of action as the dominant one. Traditional interpretations of the verbal formative reveal the most common components of verbal semantics, in particular, inclusion of the information about the subject and object of the action into the semantics of the action verb. Morphotopical analysis of a verb reveals a number of features that make up the actional complex.
One of the most characteristic components of the actional complex can be considered an action feature, the presence or absence of which in the semantic structure of the verb enables to select a few semantic classes of action verbs.
The paper considers one of the action verbs class, which semantics does not contain actional feature or contains it only partially, as an intra-object. This class of verbs has been defined as non-object oriented verbs. The quantization procedure of verb semantics of the considered units has been performed on the basis of the morphotopical analysis followed by classification.
The analysis has finally revealed that the non-object oriented verbs form a group of action verbs that includes a few subgroups: non-object oriented verbs themselves; verbs of movement; the verbs that objectify a subject-oriented action (an acting subject acts as a partial object of influence); the verbs that objectify attitude of a subject to the other subject. The subgroup of non-object oriented verbs includes the largest number of units.
LINGUOCOGNITIVE FEATURES OF PRESIDENTIAL DISCOURSE
Abstract
Presidential power institute is an integral part of the modern world life. President, being the leader of the country, uses speech and linguistic means not only at the mundane level but also in the process of performance of his official duties. In the modern world, presidential power determines largely the future of the state and the nation that elected him. In relation to specified features, the tendency of considering presidential discourse as a separate unit appeared in Russian linguistics in recent years.
The paper analyses the linguocognitive features of the presidential discourse, which is considered as a separate kind of institutional discourse and, at the same time, has characteristics peculiar for personal discourse.
The author studied the linguocognitive characteristics of presidential discourse typical for it as for a kind of institutional discourse (institutional component) and characteristics typical for the linguistic persona of the president himself (personal component).
During the study, it was determined that the presidential discourse can be fully considered as an independent type of the institutional discourse basing on the fact that it has main characteristics of the institutional discourse: communication goal, communication participants, own institute. It should be mentioned that the presidential discourse develops not only within political communication but also affects many other spheres of life (for example, education). At the same time, the paper proves the considering personal component as an integral part of the presidential discourse as each president is a linguistic persona with its linguocultural features, which influence cannot be ruled out even against the presidential discourse due process.
