The author of the article discloses the prospects of development of the world feed production for aquaculture based on the analysis of key innovative technological and market trends. The author specifies that shortage, high cost, low ecological compatibility of traditional raw materials - fish flour - are among major limiting factors in the development of production of feeds for aquaculture. This fact, in turn, limits sustainable development of aquaculture both in Russia, and in the world in general. The article presents the overview of a current status of the world industry of feed production in aquaculture, where the regional situation is studied, as well. For the first time, there is given the outlook of innovative technologies in feed production based on the alternative sources of protein (on the example of projects of leading aquabiotechnological companies) which will determine industry’s objectives for the mid-term perspective.

The article provides brief information about cardiotonic, sedative, cytostatic, diuretic, and antibacterial effects of biologically active compounds of Adonis L. (Ranunculaceae) species. Chemical studies allowed to identify the cardiac glycosides, or cardenolides: or cardenolides: adontoxin, adonitol, adonitoxigenin, acetyldigitoxin and others. In scientific medicine, it is currently allowed to use Adonis vernalis L. Other types of Adonis have a similar chemical composition and are offered as substitutes for this official species, for example, Adonis apennina L. Many Adonis species have limited natural resources, and in some regions are rare, requiring conservation of their natural populations. The search for alternative sources of medicinal plant raw materials, based on this, is relevant. The experimental part of our research was carried out using the morphological and geographical method with the involvement of information on ecology and phenology. For the first time summarizes the diagnostic features of Adonis flora of Russian flora. Previously unknown structural features (shape and size of anthers) were identified that characterize the subgenera Adonanthe and Adonis. Taxonomic study of the genus Adonis of the Russian flora allowed us to determine its species composition, clarify its systematic affiliation, and nomenclature synonyms. 9 species were identified. Of these, 6 are perennials belonging to the subgenus Adonanthe, section Consiligo, which includes 2 subsections: Amurenses (2 species) and Vernales, which is differentiated into 2 rows: Apenninae (2 species) and Vernales (2 species). Subgenus Adonis is represented by 2 sections: Adonis (1 species) and Lophocarpa with sections Aestivales (1 species) and Dentatae (1 species). For all the considered species and varieties, the main distribution areas are given. A key has been compiled to determine the wild Adonis species distributed in Russia.

Goal. The purpose of the study was to search for alternative sources of information on popu-lation’s preferences and response to problems and changes in the urban environment for use in the operational decision-making at situational centers. Materials and methods. The authors used data from search queries with keywords, data on communities in social networks, data from subject forums, and official statistics. Methods of statistical data analysis were applied. Results. The analysis of thematic online activity of the population was performed. The re-sults reflected the interest in the state of the environment, the possibility of distance learning and work, are presented. It was reasoned that measurements of population’s thematic online activity let identify needs and analyze the real-time response to changes in the urban envi-ronment. Such an approach to identifying the needs of the population can be used in addition to the platforms “Active Citizen” of the Smart City project. Conclusions. An analysis of data on online activity of the population for decision-making at situational centers is more operational, flexible and representative, as compared with the use of tools of those platforms. Such an analysis can be used as an alternative to sociological surveys, as it saves time and money. When making management decisions using intelligent information services, it is necessary to take into account the needs of the population, reflect-ed in its socio-economic activity in cyberspace.

The theoretical and methodological principles of promising managerial decisions concerning the efficiency of attracting financial resources, as well as creation of fundamentally new sources of funding for the development of energy-oriented start-ups are considered. The role and place of the sectors of innovative energy saving and alternative sources of power supply in a complex system of energy independence of the country are determined. The way and the main directions of research and development of the ways to solve the aforementioned problem are outlined. As part of the search for optimization solutions, it is suggested to use the principles of the existing statistical and mathematical apparatus, marketing achievements and achievements in network development that take place in gaming business. An analogue comparison of the principal models was carried out, during which the existing types of energy-oriented start-ups were determined and presented. A separate direction in the economic search is proposed, and its profile characteristics are outlined. The type of model is typical for Ukrainian conditions. The author proposed a method of comparing strategies for attracting financial resources into a gaming business in the core of the research. To solve the investigated problem, it is proposed to apply the property of the law of the emergence. The analysis is based on a concrete example of the functioning of the tender procedure, namely the organization of public procurement. The purpose of the article is to consider and analyze the author's proposal to focus on such an important phenomenon as the constant creation of the difference between the expected price and the final contractual price. The model of the solution is based on the systematic combination of this phenomenon and the administrative stimulation of implementation of exclusively energy-innovation projects. The combination of these two points is the basis of an optimization policy for the potential formation and maintenance of a state program to search and stimulate the sources of funding for power plants.

Supply Systems

Abstract Growing water demand poses a challenge for supply. Poor understanding of alternative sources can hamper plans for addressing water scarcity and supply resilience. The potential of three alternative supply systems in Lilongwe, Malawi and Sharm El-Sheikh, Egypt are compared using a fast, data-light assessment approach. Lilongwe water supply is based on unsustainable use of source water, while Sharm depends primarily on desalination. Both locations experience shortages due to poor system performance and service inequity. Alternative supply systems are shown to potentially contribute to supply augmentation/diversification, improving service and system resilience. There are considerable seasonal variations to consider, especially regarding storage of water. Social preferences could limit the uptake/demand for alternative water. One important conclusion is the value in addressing public perceptions of alternative systems, and assessing water end use in order to site systems appropriately. Other issues surround financing, encouraging uptake and addressing institutional/governance aspects surrounding equitable distribution. A further consideration is whether demand reductions might yield shorter-term improvements in performance without the need to institute potentially expensive alternative water strategies. Reducing non-revenue water is a priority. Such measures should be undertaken with alternative supply enhancement to reduce inequity of supply, improve system performance and increase resilience to future changes.
