A study was carried out on the possibility and necessity of operating houseboats in the water areas of Russia on the basis of the concept of the development of reservoirs and small rivers, which is currently being developed by the state within the framework of national programs. A review of the operational, overall, displacement characteristics of houseboats was carried out with consideration of various options for ship power plants, suitable for the class of floating craft with registration in the State Inspection of Small Vehicles. The use of a stationary engine (JSC AvtoVAZ) in a configuration with a hydraulic drive and a swing-out column is proposed. Calculations of the resistance of the houseboat platform hull were made using several methods. A mechanism for the choice of propellers using a free software product according to empirical methods is proposed. An alternative drive scheme is selected, a detailed model of the working process of a houseboat's hydraulic drive is selected, and a mathematical model of its operation is presented.

The article highlights the importance of a balanced structure of the economy in terms of the ratio of the production of goods and the provision of services; the history of specialization of the Russian Federation as a state and territorial entity, the key features of its structure are considered. Modern aspects of import substitution in Russia are described. A comment is made on the program “Import Substitution 2.0”, which is based on quotas for public procurement from Russian suppliers. Some problems and negative aspects of the state of implementation of the import substitution program in the Russian Federation are reflected. It is concluded that the measures for the development of import substitution were largely unsystematic, were of a fragmented nature, and in some cases even contradicted each other. Their implementation failed to optimize the structure of the economy. A set of measures to escalate import substitution is proposed, including the priority development of specific types of goods with a certain share of sales abroad and the coverage of import substitution in the sphere of services.

The growth of renewable energy sources (RES) shows the desire of the government of Kazakhstan to meet challenges that affect the welfare and development of the state. National targets, government programs, policies influence renewable energy strategies. In the future, renewable energy technologies will act as sources of a green economy and sustainable economic growth. The state policy in the field of energy in Kazakhstan is aimed at improving the conditions for the development and support of renewable energy sources, amendments are being made to provide for the holding of auctions for new RES projects, which replaces the previously existing system of fixed tariffs. It is expected that the costs of traditional power plants for the purchase of renewable energy will skyrocket, provided that the goals in the field of renewable generation are achieved. This article provides an assessment of international experience in supporting renewable energy sources, as well as analyzes the current situation in the development of renewable energy in Kazakhstan and the impact on sustainable development and popularization of the «green» economy. The study shows that by supporting the development of renewable energy sources, economic growth is possible, which is achieved in an environmentally sustainable way.

Purpose Studies have suggested that attributes are dynamic and a life cycle of product and service attributes exists. When an innovative feature is introduced, the feature might attract and delight customers. However, with the passage of time the state of the attractiveness of this feature may change, for better or for worse. The purpose of this paper is to provide a detailed model that shows the factors and related sub-factors that affect the life cycle of a feature and thereby explain the changes that may happen to a feature over time. Design/methodology/approach This model provide detailed explanations of the direct and indirect factors that affect the states of a feature, the ones that affect the rate of adoption, and the ones that trigger the changes between states. The model uses a current-market product’s feature to discuss the effects of these factors on the life cycle of this feature in detail. Findings This paper extends the theory of attractive quality attributes by identified seven states of the feature in its life cycle. These states are as follows: unknown/unimportant state, honey pot state, racing state, required state, standard state, core state, and dead state. This paper also identified eight major factors that affect the transition of the feature from one state to another. These factors include demographic, socioeconomic, behavioural, psychological, geographical, environmental, organisational, and technological factors. Originality/value The findings of this paper provide additional evidence that product and service attributes are dynamic. This paper also increases the validity of the attractive quality attributes theory and the factors that affect the state of the feature in its life cycle. The understanding of the state of the feature in its life cycle, and the factors that influence this change, helps not only in the introduction of completely new features but also in knowing when to remove obsolescent ones.

This chapter presents in a consolidated manner the step-by-step methodology to estimate the electrical energy potential of industrial wood residues considering the dependency of the efficiency of the power plants with their size. A function of the overall efficiency with power was obtained from a best curve fit of real data both taken from the literature and from Brazilian biomass-fired power plants. The methodology was applied to the determination of the electrical energy potential of wood industry residues in the State of Pará (data collected in 2004). Two cases were analyzed: one where a constant electrical efficiency of 25% was considered (independently of the amount of residues generated) and another where the proposed function of efficiency with power was used. Results show that in the State of Pará, the existent 675 sawmills generated 2.95 × 106 t in dry basis. When the dependency of efficiency with plant size is not considered, the electrical energy potential and average installed power (3140.4 GWh and 2 MWe) are overestimated in comparison to the herein proposed methodology (1868.8 GWh and 1 MWe). The present methodology, considering the efficiency as a function of the power, results in an average efficiency of 12.3% (lower than 25%).

A method is presented for estimating the possible annual risk that a hydrogen superstructure at a nuclear power plant (NPP) may have in the production of explosive hydrogen. With the observance of safety rules in terms of receiving, storing, transporting and using hydrogen, it is possible to minimize the occurrence of fi re and explosion hazard situations on the hydrogen superstructure. Scheduled repair and overhauls with all diagnostics reduce emergencies and equipment failures in the same way. However, there is a likelihood for the equipment to be found in an abnormal state (breakdown, fi re and explosion) as a result of hydrogen leaks. Depressurization of equipment with leakage of explosive hydrogen in enclosed spaces concurrently with adverse attendant factors may lead to the destruction of the electrolysis plant due to fi re and explosion. With the help of the state graph, the probabilities of a failure of electrolysis equipment because of unplanned breakdowns and possible fi res or explosions indoors due to depressurization of equipment are estimated. To this effect, possible scenarios of breakdowns of the electrolyzer in one and two workshops are considered. In the calculations of the state graph, a system of linear equations was composed for steady-state values only. The calculations have shown that for a configuration involving two electrolysis plants, the possible annual risk would increase. Minimizing the annual risk can be achieved through boosting the capacity of the electrolysis plant still in operation by increasing its productivity in hydrogen and oxygen. The effect will only be achieved if the cost of electricity from nuclear power plants is kept within 0.81 rubles/(kW·h) with a peak electricity tariff at 3.5 rubles/(kW·h).

and Scholarly Comprehension The unbalanced state apparatus in the conditions of the law enforcement system inaction and the chaotic actions of the authorities aimed at overcoming the crisis caused by the resistance of oligarchic capital eloquently testify to the need to implement systematic programs to restore and develop strategic directions of the state. Strengthening and separating regional elites from the center weakens the role and discredits central governments; the loss of control over the strategic sectors of the economy monopolized by the oligarchs requires the government to constantly seek a compromise between the interests of the state and meet the needs of corrupt capital; lack of own (national) programs for the development of education and science, national security and defense, information policy – led to the introduction of foreign ideas and concepts, sometimes outdated and sometimes irrelevant to modern Ukrainian conditions (for example, the introduction of restrictive economic instruments contribute to the destruction of countries, unable to provide their needs with their own resources at least 90%). The constant reduction of financial, natural, and human resources has led to growing public discontent with the oligarchs who «colonized Ukraine» in the late 1990s and early 2000s and, depending on Russian markets, pursue their own mercantile interests contrary to state interests. Elite change is one of the most pressing and painful issues related to the restoration of subjectivity and statehood in the Ukrainian state. None of the previous mass protests, the Orange Revolution and the Revolution of Dignity, led to a change of elites as the primary, basic cause of mass discontent. Policy inclusiveness and economic monopolization do not help restore public confidence in government actions and decisions. Domestic elites are in one way or another closely connected (dependent) with oligarchic capital – whether financial, political or media. Thus, Ukrainian elites can be confidently called pro-oligarchic, and oligarchs – representatives of domestic elites. The public demand for the de-elitization of the oligarchs has every reason to grow into another Maidan. In Ukraine, during the thirty years of independence, no conditions have been created for the professional realization of educators, scientists, doctors, journalists, engineers, etc. All so-called non-profit professions are in deep decline. Market relations have gradually transformed into market thinking – a liberal economy turns us into a market society. When measuring education, medicine, politics, friendship or family relations according to the standards of market thinking – the market suffers, and public relations, and education, medicine, science, politics, etc. – none of these categories can be market by definition.

Effective development of domestic agricultural engineering ensures the achievement of high production volumes of agri-food products. To improve the national production of agricultural machinery, the leading countries of the world provide state support to their pro-ducers. At the same time, these countries stimulate the development of the industry in order to dominate their producers in the domestic market, and to expand into the markets of foreign countries. For a long time, Russia has been the object of widespread expansion by foreign manufacturers of agricultural equipment. At the same time, under the conditions of economic sanctions, dependence on im-ported agricultural equipment limits the development of the domes-tic agro-industrial complex. Significantly reduce dependence on foreign supplies of agricultural equipment and ensure the competi-tiveness of domes- tic products should be implemented in the indus-try's current policy of import substitution. The purpose of the article is to analyze the implementation of the policy of import substitution in domes-tic agricultural machinery and assess its impact on the development of the industry. Government sup-port has a significant impact on the development of the industry, which is confirmed by statistical data and materials of market participants. Analysis of the literature and regulatory acts showed that the state financial support for the industry is carried out in 4 areas: industrial, technological, marketing and personnel. The effectiveness of state support is determined by the state of the industry, the situation on the domestic market of agricultural equipment and the achievement of support goals. To date, govern-ment support measures for import substitution in the industry have not ensured its stable development and increased competitiveness of the products produced. The authors analyzed the implementation of the state policy of import substitution in the domestic agricultural machinery in the framework of the relevant sectoral plan. Based on the analysis, a conclusion was made about the need to improve measures of state support for the industry.
