Introduction. New innovative technologies make food industry more effective. The present paper introduces a new method of hopped wort production based on novel mash filters. Study objects and methods. The research featured two new designs of mash filters. The study of the mashing process involved malt, hops, drinking water, and beer wort. The research included generally accepted methods of physicochemical and sensory research. Results and discussion. Both models differed from the traditional design. Mash filter I had a cylindrical filtration vat at its bottom with filters in the lower and upper parts of the vat. A pump was installed on the outer side of the steam jacket to produce forced circulation of the liquid medium flow through the vat. The steam jacket was covered with Corundum Classic superfine liquid thermal insulation. Mash filter II had a filtration bottom made of perforated sheet and provided intensive liquid circulation. It also had a regulated mixer that moved the mash, which significantly improved the mashing process. After the mashing, the mash passed through the filtration bottom, separating the liquid phase from the solid phase. The crushed material was discharged through a hatch in bottom. The physicochemical and sensory profiles of the obtained beer wort and beer samples complied with State Standard 30060-93 “Beer. Methods for determination of organoleptic indices and product’s volume”. Mash filter II produced beer wort of higher quality and improved the sensory properties of the finished product. This model proved more effective in extracting proteins and digestible sugars during amylolysis due to a better mixing and circulation of liquid medium flow during the wort preparation. Conclusion. The new modified mash filter made it possible to reduce the brewing time by 28.6%. Not only was it more user friendly, but it also was less heat and electricity consuming. In addition, it reduced the production area as it combined the stages of mashing and filtering.

the article explores the ways to optimize the size of the printed guide. As a result, being an edition with creolized text, the guide has components, which modernization will facilitate the introduction of interactive features into traditional genre model. As specific examples, the author offers to use activity elements in the printed guidebook from the formats that are widely used in children's literature, namely from the panorama book (three-dimensional images, inserts, paper engineering) and travel diary («journaling»).

The possibility of using local materials in the construction of structural layers of pavement is considered in the paper. The paper presents a method of technical and economic analysis, for which it is necessary to know the calculated deformation moduli of the materials being compared. Knowing the turnaround time for each of the options under consideration, it is possible, by comparing them with the payback periods, to more fully identify the technical and economic features of such options. The main criterion for the admissibility of the use of local material in the corresponding structural layer is the equal strength of pavement structures or individual structural layers made of local and imported materials. The criterion of economic feasibility of using local material can be written as an inequality. Using the principle of equivalence of systems, it is possible to replace individual structural layers of pavement, made of certain materials, with equivalent layers of stiffness from other materials, increasing or decreasing their thickness, depending on the strength characteristics of the materials themselves. The main condition for the technical feasibility of using local material has been determined on the basis of the condition of equal strength structures made from local and imported materials. A schedule for preliminary determination of the technical and economic feasibility of using local materials in the structural layers of road pavements has been built. The total value of the investment costs can be used as an additional criterion for the economic benefits of the compared options.

The paper proves that speech genres as forms of text production and interpretation claim to be one of the main objects of formal linguistic analysis in comprehensive papers on cognitive modeling – an intensively developing trend of artificial intelligence. Understanding a speech genre as a form of spiritual socio-cultural activity (artistic, scientific, political, ideological, etc.) at the level of its objectification through a system of speech actions in the text as a communication unit allows to describe the systems of speech genres in various spheres of communication. The authors analyze speech genres which objectify the main stages of an academic theoretical research. By means of artificial intelligence, the research solves the problem of recognition of the speaker’s intentions while performing cognitive-speech actions forming the genre form of a text. It contributes to the development of the fundamental problem of “understanding” the meaning of an utterance by a machine. The research is based on the interdisciplinary complex method of text analysis. In terms of software implementation, the offered approach obtains a small set of high-level linguistic features of the clauses with the templates and then trains classifiers on these features. In order to create templates, the authors carry out linguistic and psychological analysis that deals with identifying markers of cognitive and speech actions as accurately as possible in accordance with the standards of perception. In the course of our study, the authors have obtained high indexes of cognitive and speech action identification, ranging from 0.78 to 0.99.

The paper is devoted to explaining the key cognitive distinctions characteristic to translation process and its teaching. Among them are linguistic interpretation of the input text’s contents, its conceptual adaptation to the accepting culture, etc. To demonstrate them, multiple examples are given to show that translators, particularly not trained enough, often choose for basic translation dominants in the accepting culture those equivalents that are primarily purely linguistic, ignoring conceptual and cultural background of the original and the accepting culture’s notions and forms. Meanwhile, the latter help avoid such translation failures as literal / word by word translation, etc. Special attention in the paper is paid to the translation into the foreign, English, language, its contrastive culture-specific and communicative features as compared to those in the Russian language: to their cognitive dominants in communication and their cross-linguistic asymmetry and in-congruency which generate quite «natural» cross-linguistic interference in Russian-English translation. It is particularly obvious when there are extensive textual nominal ex-pressions, especially terminological, which demonstrate at present an active, extensive and productive usage in English, but present a serious problem in teaching English as a foreign language and translation into it. It is also shown that in Russian their cross-linguistic idiomatic analogues are language specific and show different patterns, but still can be adequately matched with their foreign counter-parts.

Objective. One of the most effective ways to assess thermal protection of construction facilities of various applications is thermal control. Methods. According to the national standard “Method for thermal imaging quality control of thermal insulation of enclosing structures” in force on the Russian Federation territory, the results of thermal imaging monitoring of capital and completed construction facilities are divided into qualitative and quantitative depending on set goals and objectives. Qualitative assessment involves computer processing and visual interpretation of thermograms using specialized software. Quantitative analysis of thermograms involves determining and numerically comparing parameters of reference areas and characteristics of defects detected in an object being under thermal control. Results. The paper describes particular characteristics and results of qualitative and quantitative analysis of thermograms (thermal images) obtained via thermography of fragments of external enclosing structures of a completed construction facility—an apartment building. The paper analyses existing methods of a quantitative assessment of thermograms described in regulatory documents and methodological recommendations, and presents specific examples of their application. Conclusion. Thermal imaging diagnostics makes it possible to qualitatively and quantitatively assess the level of thermal protection of the outer shell of an object under control by “decoding” thermograms and comparing calculated parameters with standard indicators.
