We have developed an intestinal wound model that includes surgical construction of an ileo-cecal patch to study the complex process of intestinal wound healing. This allows approximation of ileal mucosa to the cecal serosa and facilitates regeneration of ileal mucosa onto the serosal surface of the cecum. The regeneration of ileal mucosa can then be evaluated at different times. The wound model also allows us to determine the rate of intestinal regeneration for a known size of intestinal wound and can be compared in different situations (e.g. with and without EGF and Peyer’s patches).At the light microscopic level it appeared that epithelial cells involved in regeneration of ileal mucosa originated from the enlarged crypts adjacent to the intestinal wound and migrated in an orderly fashion onto the serosal surface of the cecum. The migrating epithelial cells later formed crypts and villi by the process of invagination and evagination respectively. There were also signs of proliferation of smooth muscles underneath the migratory epithelial cells.

Ukraine is the motherland of not only Ukrainians but also of many national minorities with different cultures and traditions. Ukraine is a Christian country in general, with non-Christian and non-Christian religions and confessional currents, along with traditional churches - Orthodox, Catholic, Protestant - rooted and actively developing non-traditional Ukrainian culture and spirituality. In Ukraine there is a complex process of spiritual revival, especially in the intellectual environment. Many are written and talk about the preservation of cultural heritage. Everywhere, monuments of architecture, art, which testify to the generally recognized historical contribution of Christianity to the development of spirituality and morality of the Ukrainian people, are restored. In our eyes, there are changes in social and religious relations.

This paper explores beginning dietetic practitioners’ perspectives on the process of becoming dietetics professionals through the use of vignettes to illuminate the complex process of professional socialization.  Embedded in these vignettes are three themes related to the socialization process that occurs in the early years of dietetic practice: congruence, resilience, and relationships.  Our findings indicate that new dietitians struggle to develop their dietitian identity.  They feel unprepared for the relational and practice realities of the workplace and find the transition from dietetic intern to dietitian challenging.  They seek many ways to cope including seeking support from others and planning for the future but some consider leaving the profession.  It is important to understand the professional socialization and identity formation processes that occur during the early years of practice to ensure that dietitians feel prepared and supported as they begin their careers.

This paper seeks to conceptualize the way Thessaloniki is promoting culinary tourism, whilst supporting and building upon local networks; engaging and co-creating an urban experience with its citizens and visitors. The aim of the paper is to suggest a potential framework that can be used as a strategic planning tool for the promotion of culinary tourism in Thessaloniki. In this direction, a food festival is being investigated. The last, is conceived by the organizers as the foundation of the idea of culinary tourism in the city. However, the findings indicate that there is a lack of active participation by the locals and not enough communication among various assets that are associated with the culinary identity of the city. In general, Thessaloniki seems to embody the ongoing struggle of a new destination, which is dealing with the complex process of branding and marketing without having the proper tools and the vital required collaboration between its structural networks. Accordingly, the research provides a lens through which the culinary culture of Thessaloniki can be used as a strategic pillar for stimulating a sustainable way of “consuming” and promoting the city’s identity; enhancing Thessaloniki’s appeal as a culinary destination.

The success of the Program of housing stock renovation in Moscow depends on the efficiency of resource management. One of the main urban planning documents that determine the nature of the reorganization of residential areas included in the Program of renovation is the territory planning project. The implementation of the planning project is a complex process that has a time point of its beginning and end, and also includes a set of interdependent parallel-sequential activities. From an organizational point of view, it is convenient to use network planning and management methods for project implementation. These methods are based on the construction of network models, including its varieties – a Gantt chart. A special application has been developed to simulate the implementation of planning projects. The article describes the basic principles and elements of modeling. The list of the main implementation parameters of the Program of renovation obtained with the help of the developed software for modeling is presented. The variants of using the results obtained for a comprehensive analysis of the implementation of large-scale urban projects are proposed.

This paper describes the organizations that were the earliest attempts to establish psychoanalysis formally in Britain. This process of institutionalization occurred between the years 1910 and 1925. Interest flowered at times in the universities and in the progressive school movement. However these seem to have been more ephemeral developments. It was the clinical and professional interest which demanded the first and most long-lasting base. A complex process of interaction between a number of organizations occurred. Their memberships initially intermingled and overlapped until the British Psycho-Analytical Society was consolidated by the mid-1920s.

The Dialogical concept of consciousness in L.S. Vygotsky and G.H. Mead and its relevance for contemporary discussions on consciousness In my paper I show the relevance of cultural-activity theory for solving the puzzles of the concept of consciousness which encounter contemporary philosophy. I reconstruct the main categories of cultural-activity theory as developed by M.M. Bakhtin, L.S. Vygotsky, G.H. Mead, and J. Dewey. For the concept of consciousness the most important thing is that the phenomenon of human consciousness is consider to be an effect of intersection of language, social relations, and activity. Therefore consciousness cannot be reduced to merely sensual experience but it has to be treated as a complex process in which experience is converted into language expressions which in turn are used for establishing interpersonal relationships. Consciousness thus can be accounted for by its reference to objectivity of social relationships rather than to the world of physical or biological phenomena.

Structural degradation of the material upon long-term thermal and force impacts is a complex process which includes migration of the grain boundaries, diffusion of the active elements of the external and technological environment, hydrogen embrittlement, aging, grain boundary corrosion and other mechanisms. Application of the fractal and multifractal formalism to the description of microstructures opens up wide opportunities for quantitative assessment of the structural arrangement of the material, clarifies and reveals new aspects of the known mechanisms of structural transformations. Multifractal parameterization allows us to study the processes of structural degradation from the images of microstructures and identify structural changes that are hardly distinguishable visually. Any quantitative structural indicator can be used to calculate the multifractal spectra of the microstructure, but the most preferable is that provides the maximum range of variation in the numerical values of the multifractal components. The results of studying structural degradation of steel 15Kh5M upon continuous duty are presented. It is shown that structural degradation of steel during operation under high temperatures and stresses is accompanied by enlargement of the microstructural objects, broadening of the grain boundaries and allocation of the dispersed particles which are represented as point objects in the images. The processes of structural degradation lead to an increase in the range of changes in the components of the multifractal spectra. High values of complex indicators of structural arrangement indicate to an increase in heterogeneity and randomness at the micro-scale level, but at the same time, to manifestation of the ordered combinations of individual submicrostructures. Those structural transformations adapt the material to external impacts and provide the highest reliability and fracture resistance of the material.
