Regulation of water use at industrial enterprises, especially at water-intensive enterprises, in a changing climate is an important economic and environmental task. One of the ways of sustainable water use at enterprises is the constant planning of water consumption and wastewater disposal in relation to the volumes and types of products produced. From a scientific point of view, at water-intensive enterprises, the most reasonable approach to optimizing water use is the development of individual technological standards for water use (water consumption and disposal). Dairy enterprises are quite water- intensive, the water use of which depends on a number of factors: assortment of raw materials for the production of products and types of products; diversification of production processes; the formation and processing of by-products, which often leads to an increase in the volume of wastewater formation in relation to the volume of water consumption; technologies for sanitizing equipment. Taking into account the specifics of production processes, a Methodology for calculating water use for enterprises for the production of dairy products, taking into account the processed raw materials and manufactured products, has been developed. The Methodology substantiates the need to change the terminology in terms of water use rationing, developed criteria for choosing two approaches to the development of individual technological standards for water use, detailed articles of water consumption and water disposal, and clarified certain parameters for their calculation. Approbation of the Methodology showed that the proposed approaches and individual parameters for calculating water use items allow the enterprise to more accurately predict the volumes of water consumption and wastewater disposal when planning production activities, which is especially important for water-intensive industries in conditions of limited available water resources.

Development of machine learning methods for spectrum processing is one of the most promising ways for gamma- spectrometry automation and accuracy improvement. Effectiveness of fully connected and convolution neural networks for quantitative γ-spectrometry analysis using scintillation detector NaI(Tl) and lead shielding is presented in the article. Semi-synthetic spectrums were used for the models training; the semi-synthetic spectrums are in channels additions of random spectrums measured at a short duration. The analysis shows advantages of artificial neural networks compare to the common analytical method of spectrum unfolding. The mean square error of activity evaluation is 2–4 times lower than the common method if measuring time is equal to 100 s. In highly standardized conditions of measuring, the advantages of convolution neural networks appear with increasing radiation source activity. Validation with sources not used in training of neural networks has shown fully connected and convolution neural networks can have advantages over the standard method when activity of γ-radiation source is relatively high.

Spent electrolytes from galvanic production are characterized by a high content of heavy metal ions, which significantly exceeds their content in natural ores. The paper shows the possibility of processing spent sulfate electrolytes from nickel plating of galvanic production to obtain pigments, which will stabilize the operation of treatment facilities, prevent the ingress of heavy metal ions into the environment, which have toxic, mutagenic and carcinogenic effects, reduce the volume of wastewater sludge formed, and also obtain a valuable commodity product that is currently being purchased abroad. The results of investigations of the coloristic characteristics of the obtained samples of pigments are presented, the effect of Fe (III) ions present in the spent electrolytes of nickel plating as a contaminant on the color characteristics and purity of the color of the obtained samples is investigated. The dependence of the color of the obtained samples on the content of Fe (III) ions in the spent electrolytes was established, which made it possible to establish the range of coloristic characteristics of pigments obtained from spent sulfate nickel-plating electrolytes (green, yellow, brown and black colors). The results of the research carried out will reduce the impact of galvanic production on the environment.

The alveolar epithelium is a dynamic tissue, consisting of cells of types I and II, covering more than 99 % of the lung inner surface and actively responding to various endogenous and exogenous stimuli. The technology of alveolocyte isolation is presented, which consists in mechanical disaggregation of tissue with subsequent processing of the resulting explants with 0.25 % trypsin solution in combination with filtration of the cell suspension through pores with a diameter of 100 µm and 50 µm. In two-dimensional static culture viable actively dividing rounded cells and large alveolar epithelial cells with cuboid or polygonal morphology, producing surfactant proteins, were visualized.

The article deals with the role of science education in explaining the modern environmental crisis and ways out of it. The urgency and peculiarities of education for sustainable development, its challenges to updating the content of natural science disciplines are considered. The directions of such updating are justified: reflection of modern state of science, fundamentality of knowledge, its interdisciplinary integration and worldview orientation. The conclusion is made that for understanding the interdisciplinary concept of sustainable development the set of special scientific pictures of the world is not enough. The problem of developing a natural-science picture of the world as an environmental component of education for sustainable development is posed. The article considers the basic categories of synthesis of natural-science knowledge into the natural-science picture of the world: nature, material unity of the world, development, system, self-organization, determinism, etc. It is determined that the natural scientific picture of the world, in its ecological aspect, is based on V. I. Vernadsky’s doctrine on the biosphere and biogeochemical migration of atoms, N. N. Moiseev’s doctrine on universal evolutionism, and the concept of sustainable development. It is concluded about the role of the natural sciences in the formation of the key concept of sustainable development – the ecological imperative.

Analysis of publications on the ecology of communities, in focus insects, over the past five years, available in the international database PubMed Central, showed that the most common scheme for assessing the species composition of different habitats are comparison using multivariate analysis of variance (PERMANOVA) and ANOSIM test, visualization of the differences using ordination (NMDS). The scheme is completed by identifying the species that are most responsible for the differences in the samples, using the IndVal and SIMPER procedures. All these methods can be implemented in the R software environment, which is currently a generally recognized standard in scientific publications in the world. The presented article includes a brief overview of the methods of comparative analysis of the insect species composition. The program code for this implementation in R using the results of our own research is also given.

This article presents the results of comparative analysis of software tools for assessing and predicting parameters characterizing the radiation situation in the event of a hypothetical emergency at nuclear facilities. To analyze the output parameters and rank the software according to the degree of conservatism, an emergency scenario at the AES-2006 design facility was selected. This scenario is associated with a decrease in the coolant temperature and, as a consequence, a change in reactivity. The results of ranking software tools for use in the activities of the Information and Analytical Center of the Department of Nuclear and Radiation Safety are presented. It has been established that the highest degree of conservatism is embedded in the operational assessment codes (HotSpot and RECASS Express). These tools make it possible to provide quick simplified calculations for the early stage of an accident at a Nuclear Facility and can be recommended for use in assessing and predicting the radiation situation as the first tools. In this case, the status of the assessment of the radiation situation is recommended to be considered preliminary, additional to the main calculations performed, for example, with the JRODOS and RECASS NT design codes, the technical capabilities of which allow assessing the radiation impact, including at significant distances from the source, as in the case of emergency situations, and within the framework of the command and staff exercises.
