Oblicza słowiańskich bóstw w „Amerykańskich bogach” Neila Gaimana
Authors: Moskal Angelika
Published: December 2021

The article takes a closer look at the interpretation of the Slav pantheon made by English writer Neil Gaiman. In his novel American Gods, two worlds collide: old gods — who came to America from Europe, Asia, or Africa over the years and similarly to immigrants tried to fi nd their niche and adapt to the new environment — and the new gods, created by modern men and a constantly evolving civilization. In the first group, we can find representatives of Slavic deities, including Czernobog. It is worth paying attention to the way Gaiman decided to portray them and confront his vision with the current state of knowledge about Slavic beliefs.
Problemy badań literatury lokalnej na przykładzie mikroregionu podwarszawskiego w latach 1989–2016
Authors: Szurek Agnieszka
Published: December 2021

This paper is concerned with ‘local’ literature as different from ‘regional’ one, local literature being addressed to a smaller, inward audience of a local community. The paper presents statistics on the number of books published in Warsaw suburban microregion, their types and genres, as well as on institutions, publishers and sponsors involved in their production. First, preliminary observations show that the number of locally published books increases yearly — this tendency is visible particularly in the last six years. The most popular genres are memoirs and history books, but the scope of local literature is much wider and encompasses such genres as novels, essays, guide books, poetry and many other. Institutions involved in the publishing process are mostly local societies, libraries and town councils and distribution channels comprise mainly local fairs and events, cultural centres, libraries and parish kiosks.

The paper sketches prospects for future investigation in local literature, drawing attention to the problems of taxonomy and new types of relations between author/creator and auditory/consumers.
Widma dawnych wartości. Kryzysy ekonomiczne w filmach o nawiedzonych domach
Authors: Sitek Wojciech
Published: December 2021

British and American cinema used a haunted house motif to tell a story about a family in a time of economic crisis. Most of the movies mentioned in the article are found on a similar pattern: not wealthy family is buying or renting a big house; they believe that this is their future dream place, so they spend their last money on house repairs. Though they are broke, they continue to live on their „American dream”.

Neoliberal myths instruct them that in American or British society there’s no place for economic losers. By this time house is reviling the symptoms of being haunted by the demons and along with the paranormal phenomena wife, husband and their children are starting to show their demons (they are extremely violent and stressed). Economic problems are linked with interpersonal family drama and the decay of social relations. Haunted house horrors are showing that the only remedy for their problems they can find in the past. Film characters from movies such as Burnt Offerings and The Amityville Horror believe that conservatism and old values are going to help their situation. In the end, it turns out that, this symbolic return to the past is just another form of ideological oppression.
Poetyka wideoklipu muzycznego
Authors: Pick Michał
Published: December 2021

Music video as a specific genre of audiovisual arts, deriving directly from tradition of film, television and music programs, became massive promotion and visual communication tool for artists at the turn of 70’s/80’s. Mentioned many times in articles about music videos, its dependence on other art fields, such as film, musical, theater arts, plastic arts etc., only strengthens us in belief that music video is an enormous hybrid form, being heir to aforementioned forms. At this intertextual base, music video has developed its own language. Cognizance and description of its components, understanding of connection rules and the essence of its individual elements is the main aim of this article. By pointing to coexistence and correlations of components such as rhythm, tempo, tone, editing etc., the text also emphasizes similarity of the music video language to the language of literature and other arts which use the same tools.

Hail to the Supermen: Ideology and Pop Culture (Chwała supermanom. Ideologia a popkultura) by Przemysław Witkowski has been considered by Przemysław Czapliński as ‘the monograph’ of pop culture created in the last thirty years. In his essay, Witkowski has made several attempts to reveal how the neoliberal and nationalistic ideologies are related to the popular or mass movies, TV series and shows, music, books, and other pop cultural phenomena. This article is a review of Hail to the Supermen… The author reconstructs the main assumptions and points out some of the most noticeable simplifications and general problems with the book.
„Biorę życie i zamieniam w idealny kamień” — rzecz o warszawskim Bazyliszku
Authors: Niewieczerzał Marta
Published: December 2021

The paper aims to examine images of the Basilisk in Polish children’s and young adult literature. It also compares the monster’s image known from traditional urban legends with its depictions in their postmodern versions. In the original variants of the legends, this creature takes various forms — supposed to be a monster that hatches from the egg laid by a rooster, it is often described as an animal the size of a hen, with a turkey neck and head and a frog’s eyes; partially a cock, partially a reptile, etc. The hybrid image of the Basilisk allows the elements of its characteristics to be used in later versions of the story and its re-workings. The analysis herein focuses on Legendy Warszawskie. Antologia [Warsaw Legends: An Anthology] (2016) which presents six versions of the Basilisk’s legend. These texts are juxtaposed with the project “Legends of Poland” by Allegro (e-book and a short movie Operacja Bazyliszek [Operation Basilisk]), as well as with the novel Felix, Net i Nika oraz Pułapka Nieśmiertelności [Felix, Net and Nika and the Trap of Immortality] (2007) by Rafał Kosik, and Księga Potworów [The  Book of Monsters] (2016) by Michał Rusinek. The author concludes that the Basilisk may be seen as a transfictional figure that transcends the boundaries of the original storyworld, which shows that — as many other legendary monsters — it should be seen not as a past phenomenon, but rather as something that still “lives” in culture and constantly evolves.
Równania mądrzejsze od swych odkrywców

Published: December 2021

This article aims to critically analyse the concept of the development of science, as proposed by Wojciech Sady in the work Struktura rewolucji relatywistycznej i kwantowej w fizyce [The Structure of the Relativity and Quantum Revolution in Physics]. The author uses Ludwik Fleck’s concept of thought styles and thought collectives to analyse the problem of how two great scientific revolutions took place in 20th-Century physics in terms of the rise of quantum theory and special relativity. Sady argues that the way of thinking of scientists is determined by the particular thought style in which they were educated, and that great scientific discoveries are not the result of “creative imagination”, but a product of deductive reasoning, in which scholars closely adhere to the formalism of mathematical theory and the results of experiments. Therefore, scientific discovery in physics is made “on paper” rather than “in the mind of a scientist.” In the “battle of equations with the imagination,” equations always win, and scientific discovery is more a result of the work of a scientific community than solitary geniuses, and can only be made at the right time in history, called the “discoverygenic situation.” The concept of the development of science presented in The Structure is directed against the incommensurability thesis and the indeterminacy thesis.
Między geniuszem, rewolucją i matematyką
Authors: Mścisławski Łukasz
Published: December 2021

The book written by Wojciech Sady is an interesting and inspiring attempt to reconstruct the mechanism of the revolution that took place in physics at the beginning of the 20th century. As part of the attempts to characterize the process of the emergence of special relativity theory and the old quantum theory, author also raises the issue of the role of genius and imagination in the process of searching for new scientific theories. The work is based on rich factual material, however, has several weaknesses and — as it seems — several places that would not require greater precision. This work aims to identify these points.
Odpowiedź moim krytykom
Authors: Sady Wojciech
Published: December 2021

In the book The Structure of Relativistic and Quantum Revolutions in Physics, I presented the anti-Kuhnian and anti-Lakatosian model of scientific revolutions. Following Fleck, I assume that scientists’ ways of perceiving phenomena and thinking about them are conditioned by the thought style acquired in the process of being introduced to the profession. So how could it happen that scientists at the turn of the 19th and 20th centuries began to think differently than they had been taught to think? My answer is that both revolutions were made by three generations of theorists. In the first generation (Maxwell; Boltzmann), the acquired knowledge and new experimental results led to conclusions that made the theoretical system inconsistent. Scientists of the second generation (Lorentz, Larmor, Poincaré; Planck, Einstein, Bohr) tried to apply these new conclusions together with old knowledge, and it was found that it was impossible to do it fully. Nevertheless, they obtained a number of new results. In the third generation (Einstein; Heisenberg, Schrödinger, Dirac and others), new conclusions began to be applied as standalone. If one were to use the Lakatosian language, some fragments of the protective belt of the old research program broke off as the cores of the new programs. In this article, I answer the objections that several outstanding philosophers of science have made against my model.
Przedsiębiorczość jako fundament dynamicznej analizy gospodarczej
Authors: Wiśniewski Jakub Bożydar
Published: December 2021

One of the more significant methodological errors in economic analysis consists in treating the concept of equilibrium — be it general or partial — as either a real state of affairs obtaining in the economy in a stable manner or a normative ideal that an optimally functioning economy should be able to reach. The purpose of the present article is to demonstrate that, in contrast to the above two views, a free economy is a process of incessant social self-development aimed at the attainment of ever more qualitatively advanced (and always temporary) states of equilibrium, whose main driving force are entrepreneurial prudence, alertness, and innovativeness. The successive sections of the present article describe several characteristic examples of supposed states of permanent stagnation or suboptimal equilibrium, which, on closer inspection, turn out to be strictly transitory, provided that a given situation is characterized by conditions conducive to the operation of entrepreneurial activities. In other words, the present article is an attempt at illustrating the thesis that entrepreneurship constitutes the foundation of dynamic economic analysis — i.e., the kind of analysis that fully incorporates the creative character of human action taking place in the context of large-scale social cooperation.
Motor development: from dynamical system approach to a neo-developmental application
Authors: Barela José A.
Published: December 2021

The aim of this study was to present a dynamical view of motor development and a few factors affecting the developmental course and rate of motor changes. The acquisition of motor skills involves one’s exploration of many body segmental configurations, followed by the selection of those that are most useful to achieve the task demands. Exploration and selection are attained through searching and the evolution and dissolution of the stable dynamical regions of coordination modes for a given task. Development then involves an interaction between the learner and environment, dissolving relatively successful dynamics in search of even more rewarding dynamics for the new task, based upon repetitive perception-action cycles. Developmental changes can occur naturally, but can also be deterministically influenced by, for example, teachers enhancing the probability of systematic change in performance over time. This influence can be through the planned introduction of interventions and providing information that drives the learner to transition to stable modes of performance and search for new body configuration dynamics required for the new task. Teachers play an important role in guiding learners through this complex developmental journey.

Published: December 2021

The advantages and disadvantages of methods for gallium nitride crystals production are considered. The convergence of the solution of the problem of electroresistive heating at determination of a thermal condition of the high pressure apparatus cell is investigated. The thermal state of the high pressure apparatus cell used to determine the solubility of gallium nitride in iron has been modeled and investigated. It is determined that the combined discretization with the use of triangular and quadrangular elements allows to reduce the time of solving the coupled problem of electrical and thermal conductivity under these conditions. The results of calculations are presented by steady temperature fields in various elements of the device. It was obtained that at the temperature in the cell control point of 1800 °С its axial difference in the volume of the investigated sample of iron was 62 °С , the maximum difference was 156 °С. The simulated cell configuration and the heating conditions defined for it are acceptable for experimental studies of the solubility of GaN in contact with Fe under conditions of high pressures and temperatures.

Cold stamping of a cartridge case blank for 40x53 mm caliber grenade launcher ammunition
Authors: Orlyuk Mikhailo , Pimanov Pimanov , Zhukov Vitaliy
Published: December 2021

Problems. The choice of a rational method for stamping blanks with two hollows is usually carried out according to the permissible degree of deformation, the coefficient of material utilization, and the productivity of the process without taking into account the effect of the deformation pattern on the final mechanical properties of the stamped semi-finished product.

Purpose of the study. Determination of a rational method for stamping a blank of a 40x53 mm grenade launcher cartridge case based on the results of computer modeling using the finite element method. Cartridge case material - AD35 aluminum alloy. The workpiece has two hollows with different diameters and depths.

Implementation technique. By means of computer modeling using the finite element method, two options for stamping of a workpiece are researched - double-sided extrusion and sequential reverse extrusion with tilting of the workpiece.

Research results. Based on the results of the research, the features of deformation according to the given schemes, as well as the energy-force parameters and parameters of the stress-strain state of the processes, are determined. It has been established that both methods make it possible to obtain blanks with specified geometric dimensions. At the same time, sequential back extrusion provides a more uniform and predictable deformation of the material along the cross-section of the workpiece, but loses in productivity to double-sided extrusion.

Conclusions. The obtained research results can be used as criteria when choosing the optimal option for stamping of a workpiece with two hollows by cold extrusion.

Антенная решетка и эквалайзер с обратной связью как единое адаптивное устройство
Authors: Джиган Виктор Иванович
Published: December 2021

В статье рассмотрена адаптивная антенная решетка (ААР), весовые коэффициенты которой совмещены с весовыми коэффициентами части эквалайзера без обратной связи, а выходной сигнал комбинируется с выходным сигналом части эквалайзера с обратной связью. Такие решетка и распределенный эквалайзер функционируют как единый многоканальный адаптивный фильтр, обеспечивающий прием полезного сигнала в условиях его многолучевости и наличия сигналов источников внешних помех. Представлены архитектура антенной решетки/эквалайзера, математическое описание многоканальных адаптивных алгоритмов его работы: рекурсивного алгоритма по критерию наименьших квадратов RLS (Recursive Least Mean Squares) на основе леммы об обращении матрицы MIL (Matrix Inversion Lemma), QR-разложения и преобразования Хаусхолдера с квадратичной вычислительной сложностью, а также простых алгоритмов по критерию наименьшего квадрата LMS (Least Mean Square), нормализованного LMS-алгоритма NLMS (Normalized LMS) и алгоритма аффинных проекций AP (Affine Projection) с линейной вычислительной сложностью. Результаты моделирования линейной антенной решетки с числом антенн/каналов, равным восьми, принимающей полезный сигнал 16-PSK, прошедший через двухлучевой канал связи, при наличии от одного до четырех источников помех с отношением сигнал–помеха (ОСП) –30 дБ по каждой помехе, при отношении сигнал–шум (ОСШ) в каналах решетки 10–30 дБ, демонстрируют эффективность предлагаемого решения.

Проанализированы параметры элементов структурной схемы фазированной антенной решетки Ка диапазона, включающей аналоговые ферритовые и дискретные полупроводниковые фазовращатели, блок управления и систему распределения мощности.
Предложен способ настройки фазирующих элементов решетки, использование которого позволяет значительно упростить и удешевить их производство. Экспериментально исследована эффективность предложенного способа настройки на примере 9-элементной линейной фазированной антенной решетки, что позволило проверить предположение об учете неидентичности фазовых характеристик элементов в ее каналах, и их влияние на параметры диаграммы направленности. Методика настройки также учитывает влияние электрических характеристик обтекателя или радиопрозрачного укрытия в случае их наличия.
Суть методики заключается в том, что все излучающие элементы антенны, кроме центрального канала, в котором фазовращатель отсутствует, закрываются радиопоглощающим материалом. Затем путем подбора вида и величины сигналов управления максимум диаграммы направленности ориентируется в направлении излучателя, находящегося в дальней зоне. Найденный сигнал управления запоминается. По одному открывая раскрывы других излучателей и настраивая их, получаем матрицу сигналов управления для заданного сектора сканирования. Таким образом формируется матрица управления фазовращателями, и при сканировании дополнительные вычислительные устройства не нужны. В результате проведенных экспериментальных исследований на примере 9-элементной линейной фазированной антенной решетки с использованием предложенной методики показано, что неидентичность параметров элементов СВЧ не влияет на быстродействие и точность установки фазового распределения в раскрыве антенны.

Совместную работу двух цифровых систем тропосферной связи (ЦСТС) можно быстро реализовать с помощью адаптивного сигнального управления одновременно на обеих станциях. Такое управление возможно организовать с помощью адаптивного алгоритма моделирования линии тропосферной связи (ЛТС) путем использования ЦСТС и контроля сигналов на выходе и входе адаптивных антенн (АдА), адаптивных передатчиков (АдП) и адаптивных приемников (АдПр) на каждой станции. Авторами использован современный цифровой тропосферный модем (ЦТМ) на одной станции и адаптивная обработка сигналов на основе специального цифрового блока управления (СЦБУ) на другой станции. В результате, адаптивное сигнальное управление одновременно на обеих станциях стабилизирует уровни тропосферных сигналов на этих станциях, что обеспечивает нормальную информационную надежность ЛТС с ЦСТС различной модификации при их совместной работе.

Published: December 2021

Introduction: The aging of China's population has further deepened, and according to the results of the seventh national census, the population aged 60 years and above in China was 264.02 million, accounting for 18.70% (China.2021).The rapid growth of the elderly population has led to an increase a geriatric orthopedic morbidity. The hip fracture is one of the common orthopedic diseases, which has posed a severe threat to the elderly's life and health (Yu, 2019).Purpose: In this study, we investigated the domestic and international literature, focusing on the analysis of DVT nursing prevention programs for elderly patients after hip arthroplasty, and proposed the current nursing research progress in preventing DVT to help elderly patients actively cope with DVT, improve the quality of life in later life, and make DVT a truly preventable disease.Method: Electronic searches using scholarly databases were employed and only significant articles that met the review objective were utilized.Findings: Currently, the main treatment option for hip fracture patients in clinical practice is surgery, and how to prevent Deep Vein Thrombosis (DVT) is an important task in the postoperative care of elderly orthopedic patients (Li, 2016). Research studies have shown that all elderly patients are at a very high risk of DVT during hospitalization, but the current trend is that 50% of patients at high risk of thrombosis are still not actively and effectively prevented from developing thrombosis for various reasons.Conclusion: This disease, which has a high incidence, a high mortality rate, and is difficult to prevent, requires increased attention and necessitates exploration to derive effective nursing intervention programs and related nursing measures to prevent reduce the formation of DVT and alleviate suffering for patient (Xu, 2016).In this review, we summarized the main nursing methods for preventing deep vein thrombosis of the lower extremities after hip fracture surgery in the elderly. Elderly patients are a special group of people, both physically and psychologically in a relatively fragile state, especially after the operation, so they need to be more careful in nursing work. In addition to general physical care, the care of their psychological state is also extremely important. This article describes in detail the physiological and psychological nursing interventions for patients, which can effectively guide and help medical staff to cope with the clinical care of such patients, and enable patients to better recover from surgery and trauma, and obtain a good prognosis.

Post-Quantum Two-party Adaptor Signature Based on Coding Theory
Authors: KLAMTI Jean Belo , HASAN M. Anwar
Published: December 2021

An adaptor signature can be viewed as a signature concealed with a secret value and, by design, any two of the trio yield the other. In a multiparty setting, an initial adaptor signature allows each party create additional adaptor signatures without the original secret. Adaptor signatures help address scalability and interoperabity issues in blockchain. They can also bring some important advantages to cryptocurrencies, such as low on-chain cost, improved transaction fungibility, and less limitations of a blockchain’s scripting language. In this paper, we propose a new two-party adaptor signature scheme that relies on quantum-safe hard problems in coding theory. The proposed scheme uses a hash-and-sign code-based signature scheme introduced by Debris-Alazard et al. and a code-based hard relation defined from the well-known syndrome decoding problem. To achieve all the basic properties of adaptor signatures formalized by Aumayr et al., we introduce further modifications to the aforementioned signature scheme. We also give a security analysis of our scheme and its application to the atomic swap. After providing a set of parameters for our scheme, we show that it has the smallest pre-signature size compared to existing post-quantum adaptor signatures.

This paper compares two approaches to determining road markings from video sequences, namely, the method of finding the markings using geometrized histograms and the method based on neural networks. An independent open dataset TuSimple is used to conduct a comparative analysis of the algorithms. Since the investigated methods have different architectures, their work is evaluated according to the following metrics: Accuracy, speed (relative FPS), general computational complexity of the algorithm (TFlops).

Previous study of this research group revealed that water from the Billings reservoir (Brazil) intended for human use (water supply and seafood) has microbiological contamination and causes lethality and brain and behavioral impairments in zebrafish. The objective of this study was to understand what have induced these impairments in the animal model. Chemical analyses on water samples from Rio Pequeno (RP), Rio Grande (RG), and Bororé (BO) rivers, as well as chemical and morphological analyses on zebrafish gills exposed to those waters were performed. Waters samples from RP, RG, and BO presented high levels of phosphorus. BO water and fish gills exposed to this water presented high levels of nitrogen. RG water caused potassium contamination in gills. Phosphorus, nitrogen, and potassium are indicators of anthropogenic pollution. RG water and fish gills exposed to this water presented low levels of calcium, which might be an indication of chemical imbalance that could lead to health problems in aquatic animals. RG and BO waters resulted in zirconium contamination in gills. BO water induced respiratory lamellae thickening in the gills, which may be the underlying mechanism for the observed hypoxia. In conclusion, behavioral, brain, and respiratory defects observed previously were induced by chemical and morphologicalb disturbances due to anthropogenic pollution in the Billings reservoir.

Utilization of Eggshell Waste As Liquid Organic Fertilizer in Rumbai Bukit District. Eggshell waste can be used for the manufacture of liquid organic fertilizer. Eggshells can come from laying hens farm waste and household kitchen waste. The utilization of liquid organic fertilizer (POC) from eggshell waste is done to minimize environmental pollution. In addition, eggshell waste recycling has economic value. The activity of making liquid organic fertilizer was carried out by 10 Kukerta students, Riau University. The location for making liquid organic fertilizer is in the yard of Mr. Masdi's house, the chairman of RW 7, Rumbai Bukit District. The method of making liquid organic fertilizer is by fermentation for 10 days at a temperature of around 40oC. The materials used are eggshells, EM4 solution, brown sugar, and water, while the tools needed are a basin, a bottle, a grinder, and a thermometer. The purpose of this program is to increase the knowledge of the residents of Rumbai Bukit on the benefits of eggshell waste in making POC. So far, eggshell waste has only been piled up on vacant land belonging to the village and as a source of air pollution. Making POC from 1 kg of eggshell powder produced 500 ml. During the practice, 7 bottles of POC were produced containing 500 mL per bottle with a capital of Rp. 5,000 per bottle. POC testing on chili and papaya plants planted in people's yards was carried out with qualitative observations of the leaves which showed wider leaves than plants that were not given POC. The results of the participation questionnaire to increase the knowledge and skills of the RW 7 Rumbai Bukit community in participating in activities and developing POC manufacturing increased by 87.5%. This outreach activity adds to the value of eggshell waste every 1 kg after it becomes a POC, which is sold for a profit of Rp. 10,000. Utilization of eggshell waste as POC can increase the economy of the Family Welfare Development (PKK) women's group by 50%.

In the present article importance of adsorptive purification of vegetable oils is shown as the most responsible technological stage. Insufficiency of scientific developments in the scope of domestic sorbents in Ukraine is pointed out. The phytosorbent with nanotubes from sunflower peel improving some quality parameters of non-refined sunflower and soybean oils to standard values for refined oils has been offered.

Some literature data on the main characteristics of a number of sorption materials (carbonaceous, natural, fibrous, and sorbents obtained from agricultural waste - Corylus avellana Lambert nuts) as a result of heat treatment are analyzed. The main sorption properties are considered; dignity; limitations. The effect of temperature on the productivity of pyrolysis of plant raw materials and the properties of the resulting carbonizates in the temperature range 150-600 °C was investigated. The duration of exposure of materials at the final temperature of the process in all experiments was the same and amounted to 1 h. Analysis of the experimental data allows us to conclude that temperature is the main factor affecting the process of carbonization of the initial plant material. Regardless of the pyrolysis atmosphere, the yield of the product from plant raw materials decreases with a significant increase in temperature. At present, the main raw material for the industrial production of adsorbents is in many studies organic substances - wood, fossil coal, peat, remnants of the processing of agricultural raw materials due to their low cost and large amount. Solving the problem of creating sorbents based on plant raw materials with the inclusion of hydrated fullerenes in their composition solved the problem of creating sorbents and environmental problems, since the waste did not always find a useful application. Concentration of water solution of hydrated C60, fast C60FWS, є molecular-coloidal systems and spherical fractal clusters, structural unit of which is micro-hydrophilic, high-hydrophilic supramolecular complex, molecules can be folded to fit into ) 24-hydration of fullerene C60 (C60HyFn). The hydrated cultivation is set in its own well-ordered, structurally heterogeneous watery middle, in which the directness and kinetics of chemical processes are seen in such, that it is necessary to be washed in order to clean.

Published: December 2021

The high efficient design of the radiation-convective recuperator with secondary emitters have been proposed, in which due to the rational arrangement of heating surfaces, as well as due to the installation of secondary emitters in flues, an increase in heat perception is transmitted to the secondary heat carrier – preheating air. High efficiency of air preheating is provided by two-stage heating: 1st stage of heating – the internal air ring channel with bilateral heating which is washed by combustion products from the parties of the central cylindrical and peripheral ring channels of combustion products; 2nd stage of heating – the external air ring channel in which unilateral heating by products of combustion from the peripheral ring channel of products of combustion is organized. Inner and outer annular air ducts (tanks), interconnected by bypass pipes. To increase the efficiency of heat transfer in the considered recuperator in the central channel of combustion products is placed emitter, which consisting of intersecting radial plates, and in the annular channel of combustion products are placed auxiliary emitters, which made in the form of flat radial edges. These emitters provide an increasing in total heat flux to the walls of the channels of the recuperator. On the basis of the conducted theoretical researches, engineering calculations and CFD – modelling the characteristics of operation of the recuperator for its installation on the furnace of secondary smelting of aluminium are defined. The main advantages of the new design of recuperator are high thermo-hydraulic efficiency, compactness and low metal consumption, ease of installation on the furnace and no need for placement in separate chimneys. It is established that the recuperator provides air heating ta,ex ~ 400 °C at an acceptable aerodynamic drag (pressure drop) on the air track (∆pa ~ 1000 Pa). Appropriate design documentation has been developed for the manufacture of the recuperator, which is installed on a pilot furnace of secondary aluminium smelting by California Die Casting (USA).
