In recent years, people have paid more and more attention to environmental protection, and environmental protection standards have become increasingly stringent. The application of denitrification technology in coal-fired boilers is an effective way to reduce nitrogen oxides, and it has also received great attention. There are two main types of denitrification technology: SNCR (selective non-catalytic reduction technology) and SCR (selective catalytic reduction technology).

One of the promising way to use solar energy is standalone PV solar water pumping systems, which are designed for irrigation and urban/rural water supply instead of grid-connected electric or diesel water pumping systems. The simplest and most common among such solar water pumping systems are  direct driven systems that do not require  expensive  and unreliable storage  batteries.

The article is devoted to the analysis of the effectiveness of anti-corruption strategies in the
Ukrainian public sector and the determination of ways of their further improvement. The main problems

The issue of legal prohibitions in national and European law has a pronounced
interdisciplinary content. The modern Ukrainian environment, through which the legal values of
European (Euro-Atlantic) and universal civilizations - principles, norms, institutions, sources of
law, legal procedures, etc. - are “refracted” (“passed through”), is quite heterogeneous and
contradictory, and this cannot but affect the peculiarities of Ukrainian law.
These problems include, in particular, the absence, unlike in many European countries, of

The need for strengthening of existing structures has recently become topical. Composite materials due to their remarkable properties, possibility to adaptation to the design requirements and facilitation of restoration measures are widely used for strengthening. This article is focused on review of restoration approaches with the use of composite materials and specific features of their behavior under various impacts. Study includes analysis of recent studies in the area, identifying gaps of knowledge and perspectives for further research.

The food industry in Ukraine is a significant contributor to the country’s economy, with a range of products that cater to both domestic and international markets. However, the increasing competition in the global market and the changing consumer preferences have made it challenging for enterprises in the 

food industry to maintain and increase their sales efficiency. This article aims to address this challenge by exploring the ways in which enterprises in the food industry of Ukraine can enhance their sales activities in the context of international economic activity.

The article examines the peculiarities of the economic evaluation of the effectiveness of the use of human capital on the example of the leading aircraft repair enterprises of Ukraine. Indicators for evaluating the economic efficiency of human capital of aircraft repair enterprises are proposed. Calculations of indicators of the effectiveness of the financial provision of human capital, indicators of the economic efficiency of the construction of the structure of human capital, and indicators of the effectiveness of financing the social development of human capital were carried out.

For Ukrainian enterprises today – in the conditions of war – activation of foreign trade and strengthening of its effectiveness are critically important tasks.

Implementation of foreign economic activity by enterprises is a complex process that requires not only a significant amount of resources, but also a competent approach to evaluating its effectiveness. Comparing the achieved results with previous periods or competitors allows to determine the current level of efficiency of such activity and to make the necessary changes to the company’s strategy.

In this paper, a novel approach for solving fuzzy goal programming is proposed.  This approach utilizes the weighted maxmin and weighted minmax methods simultaneously.  Relative weight is assigned to each fuzzy goal according to the preference of the decision maker.  A model for each of the two methods is separately stated; hence the two models are merged into one.  Moreover, the lexicographic maximization technique is applied to guarantee efficient solutions.  Therefore, the proposed approach allows the decision maker to compromise between the two methods.  Furthermore, the proposed approa
