ABSTRACTIn recent decades, we have seen an increase in the use of computers. This presents a crossroads in deciding what to do with the units that become "obsolete". As society, we have created a new type of solid waste that must be handled differently because the diversity of materials composition. In addition, at the end of their life cycle also affects the environment when the materials are disposal in landfill; i.e. plastic substrate (polycarbonate), may lead to chronic problems such as hyperactivity, infertility or even cancer.The recycling of electronic equipment is from whole parts, such as the electronic cables. Recover substances (plastics) and compounds (metals) from electronic cables could it be possible.We are looking for a solution to this problem and we created a structure of recycling to reduce the waste at the source and allows that which cannot be reduced is recycled, because computers contain 20% of thermoplastics and 6% of plastic mixtures that are the subject of this investigation.The recycled chemist hired himself since it provides capabilities that address the limitations of the mechanical recycling; you need large quantities of clean, separate, homogeneous plastic waste to be able to guarantee the quality of the final product. Chemical recycling overcomes these drawbacks, since the classification of the different types of plastic resins from of waste is not necessary.Based on the data obtained from this research, determines that the recycling of computer waste in conjunction with other plans of reduction at source makes this a viable alternative for the management of the same. Benefits that can be derived by establishing a recycling of the computer waste program is donating units or sell these affordable to low-income people who otherwise would not have access to this technology.

Theoretically, neoliberalism is acknowledged as a powerful, discursive mode of governmentality, whose key tenets widely influence sociological discourses around the role of money in attaining quality of life and happiness. However, few studies qualitatively reflect in any detail on how neoliberalism is implicated in the making of particular subjectivities. In this comparative study, participants from different income contexts (middle and low income, and downshifters) are interviewed about money meanings with attention to the particular ways of living they narrate. The findings attest to participant adoption of, and/or resistance to, lay forms of neoliberalism in the ordering of their subjectivities around key themes: life values, life goals, monetary boundaries and future understandings. Their stories show the prevalence of the neoliberal subject and clarify the practical limits of neoliberal discourses, as well as demonstrating how moral alternatives to neoliberalism can transform self-understanding and practice.

The characteristics of a new type of literary discourse having a feature of transculturality is given on the material of a poem “Prayer for the Cup” (1989–1991) a significant work by R. Bukharaev. A global, multicultural and international world is reconstructed in the poem, the existence of which is determined by the idea of transitivity — simultaneity and continuous flow, transitions from one into another: epochs, events, topos, languages. The hero of this world — is a lonely stranger, walking along the road of life, linearly opening the autonomous world of his “I”. the history of his spiritual travel correlates with the way of Christ full of suffering. The poem is full of historical and literary allusions and reminiscences from the world literary works, performing an identifying function. It is stated that identification performed by different elements of a literary text is carried out both “on the borders”, “in the interval” between different traditions, as well as “within the limits”, “inside” a homogeneous culture. Therefore, it is multiple, and meanwhile fundamentally incomplete, “split”, “fluid”, “intermediate”, “flickering”, probabilistically multiple, constantly questioning its status and revealing the growing plasticity of the subject, who is in the process of constantly recreating its own “I”. A new form of worldview, the product of which is a phenomenon of transcultural literature, is formed by synthesizing tendency. It functions within the artistic world of the poem and overcomes the boundaries between different types of culture and traditions, demonstrating the way new meanings overcome it, tolerant in their content and functions, can be appear from confrontation. An ability of an artistic image to endless mutual overflowing and transformations of meaning is a new quality of poetic language corresponding to the peculiarities of the transcultural type of artistic consciousness.

Flowers, ornamental plants, planting material (saplings) and other plants with regard to which the market with possibility of carrying out independent adequate marketing was formed, are the subject of evaluation by the experts in field of forensic merchandising. With the development of the market and market relations such goods as flowers, planting material and others are increasingly encashed in the market of Ukraine and become the objects of forensic merchandising examinations and expert researches. Special feature of merchandising researches of the plant origin objects is the use of the comprehensive approach to the estimation of their quality and cost. Researches are carried out with the purpose of determination of properties, consumer value, conformity to standards and specifications of plants certain kinds. When studying a considerable variety of flower plants, one distinguishes scientific and industrial classifications. In merchandising flowers industrial classification of flower ornamental plants which provides distribution of flower plants to the separate groups similar on biological properties, the agricultural technician of cultivation and practical application in gardening is used. During carrying out merchandising examinations on an establishment of consumer properties of certain kinds plants, namely establishments organoleptic indicators of quality and quantity of flower decorative production given for research, the expert checks conformity of this production to requirements of normative and technical documents. Requirements to quality of flower production are normalised by standards depending on production kind – cutf lowers, pottery blossoming plants, pottery decorative sheet plants, sprouts of flower decorative production, planting material, seeds of flower ornamental plants. At carrying out merchandising researches of flower decorative production, plants and saplings it’s necessary for merchandising experts to pay special attention on definition of quality indicators and a grade of plants according to standards, and also to consider data concerning age of a plant, novelty of a grade and origin country of production.

For a suspected forgery that involves the falsification of a document or its contents, the investigator will primarily analyze the document’s paper and ink in order to establish the authenticity of the subject under investigation. As a non-destructive and contactless technique, Hyperspectral Imaging (HSI) is gaining popularity in the field of forensic document analysis. HSI returns more information compared to conventional three channel imaging systems due to the vast number of narrowband images recorded across the electromagnetic spectrum. As a result, HSI can provide better classification results. In this publication, we present results of an approach known as the t-Distributed Stochastic Neighbor Embedding (t-SNE) algorithm, which we have applied to HSI paper data analysis. Even though t-SNE has been widely accepted as a method for dimensionality reduction and visualization of high dimensional data, its usefulness has not yet been evaluated for the classification of paper data. In this research, we present a hyperspectral dataset of paper samples, and evaluate the clustering quality of the proposed method both visually and quantitatively. The t-SNE algorithm shows exceptional discrimination power when compared to traditional PCA with k-means clustering, in both visual and quantitative evaluations.

In the last few decades, the subject of trust has become one of the central research topics in sociology and political science. Various theoretical approaches have crystallized, and an immense amount of empirical data has been collected. The focus on trust is for two kinds of reasons. One has to do with immanent developments in the social sciences. We have witnessed a turn from almost exclusive preoccupation with the macro-social level, that is the organizational, systemic or structuralist images of society, toward the micro-foundations of social life; that is, everyday actions and interactions, including their ‘soft’ dimensions, mental and cultural intangibles and imponderables. Another set of reasons has to do with the changing quality of social structures and social processes in the late-modern period. The ascendance of democracy means that the role of human agency is growing, and more depends on what common people think and do, how they feel toward others and toward their rulers and how they choose to participate and cooperate. The process of globalization means that more and more of the factors impinging on everyday life of people are non-transparent, unfamiliar and distant, demanding new type of attitudes. The expansion of risk means that people have to act more often than before in conditions of uncertainty. The traumas of rapid, comprehensive and often unexpected social change produce disorientation and a loss of existential security. If the ambition of sociology to become the reflexive awareness of society is to be realized, then the current interest in trust seems to be wholly warranted.

The existing standard technologies for obtaining seeds of various reproductions in farms have a wide variation in the initial harvesting parameters, mechanization and technological modes of operation, which affects the final quality indices of seed material and its cost price. Modernization of the working parts of machines and units that provide the technology of loading and reloading operations will improve the quality of grain at this stage of harvesting. The installation of a new type of transporting device in a typical grain-handling machine loader allows to reduce the crushing and damage of grain by more than 20%.
