Existing technological schemes of lime-carbon dioxide purification of diffusion juice include lime treatment (defecation) and two-stage treatment with carbon dioxide (saturation) with sediment separation. Improving cleaning methods aimed at increasing its efficiency is an urgent task. Lime-carbon dioxide purification of the concentrated sugar-containing solution before boiling allows to improve the quality of sugar, reducing the syrup color and increasing its natural alkalinity. The proposed purification scheme, which includes overcarbonation to low syrup pH values (8 and below), its mixing with carbonated syrup and adding activated suspension of II saturation sediment, makes it possible to obtain a purified solution with an increased effect of adsorption purification, with a significantly low content of high-molecular compounds and their calcium salts. The results of the study of various schemes for the purification of syrups in a laboratory setup have been presented. A method for purification of concentrated sugar-containing solutions, protected by a patent of the Russian Federation for the invention, has been developed, which provides for the reduction in the consumption of calcium hydroxide by 0,10–0,12% of CaO by weight of the product or by 0,04% by weight of beet.

Abstract An urgent task in the training of personnel of industrial enterprises is the development of the required amount of practical skills. In the context of a pandemic, restrictive measures, as well as the high cost and danger of conducting training on real equipment, virtual laboratories are becoming one of the most promising training tools. The virtual laboratory includes a visualization system (many 3D objects, animations and effects), as well as software components, databases, modules for logging and assessing the quality of exercise performance. Within the framework of this work, the task of developing a visualization system for virtual laboratories is considered. A structural diagram of the visualization system is proposed, illustrating all the necessary elements for creating virtual stands, an implementation algorithm is drawn up. The software implementation is described on the example of a laboratory setup for performing the Reynolds experiments.

This article examines the issue of the effectiveness and quality of the implementation of parliamentary control in the spheres of spirituality and culture, as an aspect of ensuring national security in the modern conditions of the hybrid aggression of the Russian Federation against Ukraine. It is noted that parliamentary control in Ukraine is extremely insufficient and rather contradictory, which does not yet allow to talk about the stability of parliamentary control as such, about its proper scientific understanding and legal consolidation in modern conditions, especially in the context of the hybrid aggression of the Russian Federation against Ukraine. It was stated that social changes caused by globalization processes affect the state of ensuring national security in such spheres as culture and spirituality. Currently, this issue has not been studied enough, and therefore needs further development. It was noted that in the field of culture, certain positive changes in the implementation of state (parliamentary) control have been achieved in recent years. However, in the sphere of spirituality (spiritual culture) and in the related religious sphere, as a result of the ideological sabotage and special informational operations carried out by the Russian Federation, a spiritual crisis has actually been generated in Ukraine, the resolution of which is an urgent task of the state power. Parliamentary control in these areas, which should be carried out through the prism of national security, is virtually absent. A number of proposals have been worked out, which are advisable to be introduced into the process of exercising parliamentary control over the aforementioned spheres.

The article analyzes the problems of the manifestation of risks of shadow and criminal activity in the life support system of citizens of the Russian Federation, the dissemination of which requires the development of effective measures to prevent and eliminate them. The most important issue is the formation of an effective economic security system with an emphasis on the new quality of life support for citizens of the Russian Federation in an adequate combination with the high growth rate of NTP in the Russian economy. The new technological structure emerging from the new achievements of scientific and technological progress involves the harmonization of the pace of scientific and technological development, combined with an adequate improvement in the quality of life support for citizens performing such achievements. Owing to this fact formation of new quality of the housing and communal services (HCS) as bases of life support of citizens becomes a prerequisite of increase in performance and intellectualization of human work. With this in mind, early recognition, prevention and elimination of risks of shadow and criminal activities in the housing and communal services system (housing and communal services) is considered as a significant mechanism to increase the effectiveness of the system of comfortable life support for citizens of the Russian Federation. The existing lag in the development of a high-quality and comfortable system for providing citizens of Russia on the basis of housing and communal services, the subject of which is the provision of quality and comfortable services, influenced by numerous risks of shadow and criminal influence, becomes a condition for intensifying economic development and increasing labor productivity on this basis. The need to develop and use modern scientific and technical achievements, especially in the field of digitalization, is emphasized in order to increase the efficiency of the economic security system of housing and communal services organizations based on innovative control mechanisms - internal control, audit, compliance control, taking into account financial investigations in order to prevent and eliminate the risks of shadow and criminal activities in the housing and communal services system.

The existing legislation determines the education as "an integral and focused process of teaching and upbringing, which represents a socially important value and shall be implemented so as to meet the interests of the individual, the family, the society and the state". However, even in this part, the meaning of the notion ‘socially significant benefit is not specified and allows for a wide range of interpretation [2]. Yet the more inconcrete is the answer to the question – "who and how should determine the interests of the individual, the family and even the state?" The national doctrine of education in the Russian Federation, which determined the goals of teaching and upbringing, the ways to attain them by means of the state policy regulating the field of education, the target achievements of the development of the educational system for the period up to 2025, approved by the Decree of the Government of the Russian Federation of October 4, 2000 #751, was abrogated by the Decree of the Government of the Russian Federation of March 29, 2014 #245 [7]. The new doctrine has not been developed so far. The RAE Academician A.B. Khutorsky believes that the absence of the national doctrine of education presents a threat to national security and a violation of the right of citizens to quality education. Accordingly, the teacher has to solve the problem of achieving the harmony of interests of the individual, the family, the society and the government on their own, which, however, judging by the officially published results, is the task that exceeds the abilities of the participants of the educational process.  The particular concern about the results of the patriotic upbringing served as a basis for the legislative initiative of the RF President V. V. Putin, who introduced the project of an amendment to the Law of RF "About Education of the Russian Federation" to the State Duma in 2020, regarding the quality of patriotic upbringing [3]. Patriotism, considered by the President of RF V. V. Putin as the only possible idea to unite the nation is "THE FEELING OF LOVE OF THE MOTHERLAND" and the readiness for every sacrifice and heroic deed for the sake of the interests of your Motherland. However, the practicing educators experience shortfalls in efficient methodologies of patriotic upbringing, which should let them bring up citizens, loving their Motherland more than themselves. The article is dedicated to solution to this problem based on the Value-sense paradigm of upbringing educational dynasty of the Kurbatovs [15].
