The relationship between the civilisation illnesses and incorrect nutrition can be considered as demonstrated. The functional foods having one or several nutritional- biological advantage can contribute to the healthy nutrition and to improving the quality of life. Beside the healthy nutrition it is an another important requirement that the food does not contain pathogens or substances of chemical and biological origin namely it has to be safe. In this publication the foods of animal origin were investigated in the point of view of public health hazards arising during their production and processing.The contamination and infection of food raw materials, the consequence of chemical substances getting in or developing it the food, the judgement of food deviring from genetically modified or cloned animals are discussed.

The most rational and promising way to solve the problem of healthy nutrition, according to most scientists and specialists, is to combine raw materials of meat and vegetable origin. To obtain functional products, an important factor is not only the enrichment of food products with vegetable raw materials, but also the stabilization of the quality of meat systems. The use of vegetable components in addition to raw meat makes it possible to obtain combined products that are diverse in composition, which significantly expands the range of high-quality products and creates the possibility of designing products of a given composition. Also, it was found that the content of only meat or vegetable protein in food has less biological value than their mixture. The combination of vegetable and meat protein is well achieved in paste products. The article highlights the development of technology for the production of functional foods using meat and vegetable raw materials. The study objective was the development of combined food products for medical, prophylactic and functional purposes. An improved recipe for meat paste with the addition of vegetable ingredients is proposed. According to the developed technology, experimental development of several samples of cooked sausage “Appetitnaya” was carried out on the basis of a balanced ratio of the main food components, providing increased digestibility and digestibility. Production tests of product development were conducted. Quality assessment by organoleptic, physico-chemical and microbiological indicators of the finished product was carried out according to generally accepted methods.

The quality of raw materials and goods of animal origin depends first of all on the safety of feed, their balance in terms of the main nutrients and digestibility by the body. As a rule, the lower the quality and safety of feed, the lower the productivity of all types of animals and poultry. The quality of feed is influenced by all stages of their production: growing conditions, harvesting and storage, processing technologies, canning and preparation for feeding. Where high-quality feed is used in diets, maximum productivity and high realization of the genetic potential of animals are obtained. During the storage and processing of plant and animal raw materials its physic and mechanical, biochemical, sanitary and microbiological properties change. This can be avoided only by observing the sanitary and hygienic requirements for bagging, harvesting, and storing feed. The quality of feed is confirmed by its physical, chemical, organoleptic, microbiological and other indicators, which determines the variety of feed control methods at all stages of their turnover. In this connection, the development and strengthening of control over the quality and safety of feed and feed additives is one of the important tasks of modern animal feeding science. The purpose of the work was to carried out a comparative assessment of four samples of the starting compound feed SK-3 for piglets of different producers. The experimental part of the work has been carried out in the laboratory of veterinary expertise at the compound feed plant LLC “Athens-Volga”. For the study of compound feed an average sample was taken from each sample, separating from the combined sample using a hand scoop according to Federal standard 13496.0-2016. Methods of sampling. Quality and safety control was carried out according to organoleptic, physic and chemical, microbiological indicators and the content of mycotoxins in compound feed. Monitoring of compound feed of the compared samples of the starting compound feed for piglets SK-3 according to the studied indicators has shown that all samples meet the sanitary and hygienic requirements of Federal standard of our country.

Purpose The purpose of this paper is to empirically investigate how context influences the quality of business relationships. This theoretical question is studied from the point of view of trust, one of the important components of business relationship quality. The authors study how trust is related to the dynamics and management of the business relationship in the context of an emerging market. Design/methodology/approach This paper is based on qualitative interviews with 15 spare-parts resellers in the Tunisian automotive industry. The authors take a monadic view, interviewing resellers about their relationships with their wholesalers-importers. The decision to undertake the research in Tunisia is based on three factors. First, Tunisia is an emerging country and there is very little published research based in the Maghreb countries. Second, the Tunisian automotive parts market structure is relatively simple and, hence, easily understood, with most spare-parts being imported because of the low level of local production. Third, the actors in the study are all Tunisian companies, so research allows us to explore relationships between local companies in an emerging country. Findings The authors find that different kinds of trust play different roles over the dynamics of the relationship. Perceived trust is more important at the emergent stage of a relationship, and as the two parties learn from each other, experienced trust becomes more important in the established relationships. The initial perceived trust creates the possibility of building trust, and when mutual trust exists between the parties, it motivates them to maintain the relationship, but there is always the threat of the degradation of the quality of the relationship because of the violation or destruction of the trust. Research limitations/implications This paper shows that more care should be taken when using trust as the variable under scrutiny. Different aspects of trust manifest themselves at various stages of the relationship building cycle. Practical implications The results emphasize that when initiating a business relationship, managers first need to create perceived trust. Thereafter, once trust is built up, it is the trust that may “manage” or act to control the on-going relationship as long as the partners’ behavior or network changes do not violate the trust. Originality/value The results of this paper show that there is a mutual but not necessarily symmetrical or balanced influence of trust on the behavior of the partners involved. The influence of the different parties is dependent on the power architecture, the history of the relationship and the network position of the actors.

Orientation: In recruiting and developing senior leaders for the organisation, great emphasis is placed on the personality of these individuals and on the resulting manifestations of their behaviour in the work context.Research purpose: The objective of this study was to explore the relationship between integrity and derailment to identify the dimensions of integrity that may reduce the risks of derailing in a group of senior leaders.Motivation for the study: As organisations become more complex, a higher quality of leadership is demanded. The quality of leadership is often determined by, among other things, the level of leaders’ integrity and the manner in which they are able to manage their own derailment at work. In this study, integrity is defined as the conflict and balance between our instincts (i.e. vices) and our ability to reason (i.e. our virtues), while leadership derailment is defined as the way in which leaders behave under stress or when they overuse a particular strength. Both constructs are of particular concern when they manifest in the organisation’s pool of high-potential leaders, who are the organisation’s future successors. However, most derailment cases are predictable and can be managed effectively with proper intervention.Research approach/design and method: A cross-sectional quantitative, correlational research design was followed. A non-probability purposive sample of 108 senior leaders in companies in Southern Africa participated in the study.Main findings: The results enabled the researchers to assess the relationship between integrity and derailment in order to identify the dimensions of integrity that are associated with a lowered risk of derailing in a group of senior leaders. It is apparent from the results that several of the integrity dimensions measured in the current study acted as significant predictors of derailment. The results indicate that the Giotto scales predict five of the Hogan scales to a degree that could be regarded as practically significant and are associated with medium to large effect sizes). These are Excitable, Cautious, Leisurely, Bold and Colourful. The prediction of Cautious can be described as practically important, while the prediction of the remainder of the Hogan scales was practically non-significant.Practical/managerial implications: From a practical point of view, the research findings allow leadership development practitioners, consultants and coaches to assist leaders in identifying the ways in which leaders will probably derail based on the results of the Giotto integrity test. Those involved in the development of leaders will also be able to develop the leaders’ level of integrity in order to reduce unnecessary derailment at work.Contribution/value-add: The study findings contribute valuable information on the relationship between integrity and derailment and the dimensions of integrity, which may reduce the risks of derailment of senior leaders.

Rice is one of the most abundant food crops in the world and its straw stands as an important source of fibres both from an economic and an environmental point of view. Pulp characterization is of special relevance in works involving alternative raw materials, since pulp properties are closely linked to the quality of the final product. One of the analytical techniques that can be used in pulp characterization is near-infrared spectroscopy (NIRS). The use of NIRS has economic and technical advantages over conventional techniques. This paper aims to discuss the convenience of using NIRS to predict Kappa number in rice straw pulps produced under different conditions. We found that the resulting Kappa number can be acceptably estimated by NIRS, as the errors obtained with that method are similar to those found for other techniques.

Abstract Water quality is subject to frequent changes in the Drean-Annaba alluvium aquifer. Water-rock interaction can not be the only process that produces the observed modification, but dryness that the country knew during the last two decades has highly contributed to the water quality changes. During this period, irregularities in the distribution of rainfalls, in time and space, have been observed. As a result, a periodicity in hydrochemical changes in water of wells and rivers is noticed. Statistical, the principals components analysis (PCA) tools and Tickel diagram have been used to show, through chemical presentation, these effects. The results show, indeed, seasonal changes of water quality for the period 1999-2000. From a cationic point of view, a competition between alkaline and alkaline earths is shown. On the other hand, from an anionic point of view, there is a transition from chlorides to sulphates and may be to bicarbonates. The present work was carried out in a relatively small area and this was useful to show the relationship that existed between dryness and water quality of both the aquifer system and surface water.

Penelitian ini difokuskan pada tiga hal yaitu: (1) menemukan ciri-ciri musikal lagu gedé; (2)menunjukkan perbedaan relasi musikal antara lagu gedé dengan pertunjukan wayang golék dankiliningan; dan (3) menunjukkan kompleksitas hubungan garap di dalam lagu gedé, yaitu hubunganantara nyanyian sindén dengan nyanyian alok, rebaban, gambangan, dan kendangan. Penelitianini menggunakan pendekatan etnomusikologis didasarkan pada cara kerja ala Wim van Zanten,yaitu memadukan aspek musikologis dan antropologis. Musik ditempatkan sebagai objek utamasekaligus dasar relasinya dengan persoalan-persoalan kebudayaan dan masyarakat. Hasil penelitianini menunjukkan bahwa lagu gedé menunjukkan peran, proses, interaksi dan kompleksitas garapnyakhusus. Pada sisi pencipta lagu, lagu gedé diakui sebagai pengguritan yang sulit dan langka. Padasisi penyaji, membawakan lagu gedé diperlukan persyaratan seperti: modal vokal bagus, menguasaiperbendaharaan lagu dan laras, terampil menafsir garap lagu dan memberi sénggol-sénggol unik. Denganketiadaan lagu gedé, mutu garap kesenimanan sinden dan pangrawit dan jalinan interaksi kemampuanmusikal di antara pemeran garap vokal, rébab, gambang, dan kéndang mengalami keterbatasan.The Musical Characters of Lagu Gedé Kepesindenan on Sundanese Karawitan. The researchis mainly focused on the three things: (1) to find the musical characteristics of lagu gedé; (2) to show thedifference on the musical relationship of lagu gedé song with a puppet show and kiliningan; (3) to show thecomplexity of the working relationship on lagu gedé, such as the relationship between the singing of Sindenand the hymns of alok, rebaban, gambangan, and kendangan. The ethno musicological approach of lagugedé is based on the work method of Wim van Zanten which is a musical approach with an anthropologicalperspective. The two aspects – musicological and anthropological – are respectively combined. Music isintensively placed as the main object in order to discover the basis of its relation with cultural and socialissues. The results of the research on lagu gedé show the role, process, interaction, and complexity of the musicalinterpretation which are characterized by a slow tempo. From the composer’s point of view or the musicalcomposition, lagu gedé is recognized as a difficult and rare form of pengguritan. From the performers’ pointof view (the sinden or female vocalist and the pangrawit or musician), a number of special skills are requiredin performing lagu gedé. These may include a good voice, a good command of the musical repertoire, tuning,and musical composition, and the ability to interpret the music and provide the unique sénggol-sénggol aswell. By the absence of lagu gedé, there will be more limited quality of interpretation and artistry of thesinden and pangrawit, and the musical skills and interaction among the musicians (such as the vocalist,rébab, gambang, and kéndang players).

This article describes the study of existence of the relationship between individual factors of sustainable development from a qualitative point of view. It is revealed that new essential characteristics of the “middle class”, connected with sustainable development, are being formed. This makes it necessary to display them by introducing a new concept of “creative middle class”. The purpose of this study is to identify the relationship between improving the environment, the quality of life of the population, the processes of formation of a creative middle class and the results of socio-economic policies to ensure sustainable development of the territory. This study was conducted on the basis of a semi-formalized mass interview. Sustainability is considered for two regions of Siberia (Kemerovo and Tomsk regions), which differ in the specialization of economies: the mining region and the innovation region. In the RIA rating of the Russian regions on the quality of life, these regions, despite the different specialization of economies, occupy fairly close positions, being in the middle of the rating table. The hypothesis regarding the role of the creative middle class as the main subject and the main driver of socio- economic transformations for ensuring the sustainable development of the region in the long term and improving the quality of life of the population has been partially confirmed. This can be explained by the fact that the process of forming a creative middle class is at the initial stage. Manifestations of innovative features in the economic and social activity of the subjective middle class in the Tomsk region were not identified.

A transparent Yb3+:NaY(WO4)2single crystal with dimensions of 30 mm (diameter) × 40 mm has been grown by the Czochralski method. The high crystalline quality of the as-grown Yb3+:NaY(WO4)2crystals was confirmed by high-resolution X-ray diffraction. The effective segregation coefficients of elemental Yb, Na, Y and W in Yb3+:NaY(WO4)2were measured using the X-ray fluorescence method. Powder and single-crystal X-ray diffraction data of NaYb0.05Y0.95(WO4)2are reported. The structure refinement shows that NaYb0.05Y0.95(WO4)2crystallizes in the tetragonal space groupI41/a, witha=b= 5.2039 (2),c= 11.2838 (9) Å, α = β = γ = 90°,V= 305.57 (3) Å3andZ= 2. A series of possible growth faces (hkl) were determined from the crystal lattice and symmetry according to the Bravais–Friedel Donnay–Harker theory, and the relationship among crystal structure, growth habits and crystal morphology is discussed. In addition, the thermal properties of the crystal, including the specific heat, thermal expansion, thermal diffusion and thermal conductivity, were carefully investigated. The anisotropy of the crystal thermal conductivities is explained from the point of view of the crystal structure.
