Biogenic amines are nitrogen compounds which are products of the decarboxylation of free amino acids. They are produced with the participation of bacterial microflora producing enzymes, and they may be introduced together with food into the human body. The highest amounts of biogenic amines are found in meat, fish and cheeses. Consumption of products containing biogenic amines can cause food poisoning and allergies in consumers. The most common amines in cheeses are tyramine, histamine, putrescine, cadaverine and 2-phenylethylamine. The formation of amines depends on the technology of food production, storage conditions (temperature, time, pH, moisture), the quality of the raw materials (the content of free amino acids, proteins, salts, sugars) and the presence of microorganisms producing decarboxylases. This article describes different types of biogenic amines, their formation, detection methods and health risks to consumers. Information on the harmfulness of biogenic amines and on factors conducive to their production may help prevent poisoning with these compounds.

Relevance. Sheep wool is one of the types of products that requires high energy costs of feed. Therefore, sheep breeding should be based in regions that allow for their soil and climate conditions to contain animals of this type with the lowest material costs. One of these regions of the Russian Federation is the southern Federal district. Assessment of the state of fine wool production in the region makes it possible to develop a science-based strategic program for managing this process, which can be universal and used in relation to other territories. This is the relevance of our research.Methods. Analytical, statistical, computational, and biometric research methods were used for their implementation.Results. As a result, it was found that there is currently a certain stagnation in the production of Merino wool in the Southern Federal District. Therefore, additional means of regional and federal support are needed to encourage producers to increase the number of sheep that produce uniform wool. Certification of wool based on methods consistent with international standards of the IWTO countries in this territory revealed a number of qualitative features of the raw materials produced. The largest share in the structure of produced wool — 79–93% — is occupied by raw materials with a diameter of the cross section of the fibers of 20.6–23.0 microns. Very insignificant is volume of wool diameter of the cross section of the fibers less than 20.5 microns — less than 1%. It is produced only in the Rostov region. It was also established that the share of wool with contamination by easily-and difficult-to-separate impurities at the level of 1.5–2% is from 38 to 100% of the produced wool in different regions of the district. The authors propose a system of complex selection and technological techniques to improve the quality of fine wool produced.

This research work was conducted to demonstrate the mechanism of white board marker ink production using locally sourced raw materials such as charcoal and used lube oil. In the production of the ink, the charcoal served as a pigment, used lube oil served as the primary binder or resin, ethanol served as solvent and gum Arabic served as an additive. The charcoal was obtained from processing of Mango, Oil bean (Ugba) and rubber trees, which were further crushed to their finest particles respectively and the used lube oil was obtained from mechanical engineering servicing unit of automobile engines. The crushed charcoal samples were characterized to determine the physio-chemical properties of some mineral elements such as Ca, Cu, P, K, C, S, N. however the mineral component that controlled the production of this ink was the Carbon content. The different ink samples were formulated in terms of odour, colour, hazardous reaction, pH, density and viscosity and compared with that of international standards. Results obtained showed a good match, indicating the reliability and the quality of the produced white board marker ink. The pH results for Ugba ink = 5.43, Rubber ink = 6.79, and Mango = 7.41. Empirical models were used to predict concentration with that of experimental values, a plot of concentration against time in terms of production yield revealed that the order of magnitude was rubber>Ugba>Mango whereas in terms of penetration and writing ability Ugba>rubber>mango. Furthermore, the research demonstrates the significance of the characteristics of the charcoal and the used lube oil in the quality of the end product. Finally, the research revealed that ink produced from the oil bean (ugba) charcoal and lube oil was best in terms of write-ability and quality in the production of white board marker ink.

Although North Korea is one of the most closed countries in the world, it has long been pursuing international cooperation with other countries in order to upgrade the quality of its film industry to international standards. Preceding studies on this topic have mainly focused on the political influences behind filmmaking in general and very few studies have exclusively dealt with North Korea’s international co-productions. In this respect, in order to develop a comprehensive understanding of the internalization strategy of North Korea’s film productions, this paper uses the global value chain as a framework for analysis. This approach helps understand the internationalization pattern of each value chain activity of film co-productions in terms of the film location and the methods for collaborating with foreign partners. By dividing the evolution of North Korea’s international co-productions into three periods since the 1980s, this paper finds that although North Korea has shown mixed results with different aspects of the film value chain, it has generally improved its internationalization over the three periods. This paper further provides strategic directions for North Korea by learning some of the successful Chinese experiences in the film sector regarding collaboration with foreign partners—to foster a win-win situation for all involved parties.

  The article is devoted to the study of the chemical composition, physical and thermal-pfysical characteristics of damp apple pomaces and the identifying patterns of influence of drying temperature the functional composition and gel-forming ability of pectin. The research is aimed at obtaining initial data for the subsequent calculation of the main technological, hydro-mechanical, thermal, structural and economic characteristics of devices for drying the plant raw materials, ensuring the environmental safety and high quality of pectin-containing raw materials, the reducing heat and energy costs. As a result of the study of the thermal characteristics of apple pomaces, the critical points (temperature conductivity – 16.5 x 10-8 m2/s, thermal conductivity – 0.28 W/m K, heat capacity – 1627 j/(kg K)) at a humidity of 56 % are determined, which characterizing the transition from the extraction of weakly bound moisture to the extraction of moisture with strong bonds (colloidal, adsorption). It was found that the pomaces obtained from apples of late ripening have a higher content of solids (21-23 %), soluble pectin and protopectin (2.5-4.5 %). Dried pomaces obtained from apple varieties of late ripening contain up to 25 % pectin, which allow us to recommend them as a source of raw materials for the production of pectin. The optimum modes of preliminary washing of raw materials are offered, allowing to the remove the ballast substances as much as possible. It is established that when the drying temperature increases, the destructive processes are catalyzed: the strength of the pectin jelly and the uronide component and the degree of pectin esterification are reduced. The optimum drying temperature of damp apple pomaces is 80 0C, at which the quality of pectin extracted from the dried raw materials is maintained as much as possible. It is shown that the most effective for the pectin production is a fraction with a particle size of 3-5 mm, which allow us to extract up to 71 % of pectin from raw materials.

Software Development Life Cycle

The present article describes setup, configuration and usage of the key performance indicators (KPIs) of members of project teams involved into the software development life cycle. Key performance indicators are described for the full software development life cycle and imply the deep integration with both task tracking systems and project code management systems, as well as a software product quality testing system. To illustrate, we used the extremely popular products - Atlassian Jira (tracking development tasks and bugs tracking system) and git (code management system). The calculation of key performance indicators is given for a team of three developers, two testing engineers responsible for product quality, one designer, one system administrator, one product manager (responsible for setting business requirements) and one project manager. For the key members of the team, it is suggested to use one integral key performance indicator per the role / team member, which reflects the quality of the fulfillment of the corresponding role of the tasks. The model of performance indicators is inverse positive - the initial value of each of the indicators is zero and increases in the case of certain deviations from the standard performance of official duties inherent in a particular role. The calculation of the proposed key performance indicators can be fully automated (in particular, using Atlassian Jira and Atlassian Bitbucket (git) or any other systems, like Redmine, GitLab or TestLink), which eliminates the human factor and, after the automation, does not require any additional effort to calculate. Using such a tool as the key performance indicators allows project managers to completely eliminate bias, reduce the emotional component and provide objective data for the project manager. The described key performance indicators can be used to reduce the time required to resolve conflicts in the team, increase productivity and improve the quality of the software product.
