Using a soft chemical process that involves nitrates and heat annealing, nanoparticles of undoped ZnO and praseodymium, aluminum-codoped ZnO may be produced. XRD, SEM with EDS, and FTIR analysis determine nanocatalyst structures, morphologies, and chemical bonding. PL and UV spectroscopy examines optical characteristics. The peak in the FTIR spectral line at 714 cm-1 in the study indicates M-O stretching in the samples and ZnO's interaction with the Pr and Al matrix. XRD patterns indicated prepared nanoparticles with nanosizes ranging from 40.07 to 38.65 to 36.84 to 38.87 to 39.91 nm. SEM analyzed nanoparticle size, shape, and interaction with the Pr and Al matrix. EDS determined NPs purity. UV-vis spectra of ZnO-Pr/Al nanocomposites showed UV absorption similar to ZnO nanoparticles. Doping ZnO with Pr and Al shrinks the bandgap and slows photogenerated electron-hole pair recombination without changing its crystalline structure.

Background — The significance of cytokine activation and immune inflammation in subclinical damage to cardiomyocytes and resulting development of the congestive heart failure (CHF) is frequently discussed in published studies, as well as whether there are cardiac lesions in COVID-19 survivors identified by the speckle tracking echocardiography (STE). Objective — To examine the association of echocardiographic parameters with indications of immune inflammation in patients recovered from COVID-19 pneumonia depending on segmental longitudinal strain (LS) of the left ventricle (LV) identified by STE. Methods — Our study encompassed 216 patients (51.1% men, mean age of 50.1±11.1 years) distributed among two groups: Group I (n=108) included study subjects with segmental LS (≥3 LV segments) revealed by the STE; Group II (n=108) comprised patients without visually detectable LV lesions. All patients were examined three months after COVID-19 pneumonia. Results — Groups did not differ statistically significantly in terms of LV ejection fraction (68.7±4.3% in Group I vs. 68.6±4.3% in Group II; p=0.916). Global LS was significantly lower in the Group I than in the Group II at the time of the control follow-up visit three months later (-18.2 [-16.7; -19.4] % vs. -20.6 [-19.5; -22.1] %, respectively; p<0.001). When analyzing laboratory indications of immune inflammation in groups, we revealed statistically significantly higher values in Group I vs. Group II in the concentrations of interleukin 6 (3.1 [2.4;3.9] pg/mL vs. 2.5 [3.8;4.7] pg/mL; p=0.009), C-reactive protein (4.7 [2.9;8.3] mg/L vs. 3.0 [1.5; 5.3] mg/L; p<0.001), and tumor necrosis factor α (6.0 [4.8;4.1] pg/ml vs. 5.0 [4.0;6.4] pg/ml; p=0.001). In Group I, we detected diffuse lesion of LS (≥4 segments of the same LV level; 38.0% of patients) and regional lesion of LS (≥3 segments corresponding to the blood supply pools of the anterior, circumflex, or right coronary arteries; 62.0% of patients). According to logistic regression, the LS of the basal LV level (OR 3.028; 95% CI 1.909-4.802; р<0.001) in combination with LS of the apical LV level (OR 1.287; 95% CI 1.099-1.507; р=0.002) and LV lateral wall annular velocity assessed by tissue Doppler imaging, peak e’ (OR 0.774; 95% CI 0.657-0.911; р=0.002) had an independent relationship with each of diffuse and regional LS lesions. Conclusion — Based on STE data, we have identified a relationship of diffuse and regional LV lesions with features of systolic and diastolic LV dysfunction and markers of immune inflammation in patients three months after COVID-19 pneumonia.
„Wykreśliliśmy parę fragmentów…” Cykl Nowa baśń Teodora Parnickiego w dokumentach Głównego Urzędu Kontroli Prasy, Publikacji i Widowisk

Published: July 2023

Celem artykułu jest ukazanie, jak urząd cenzury obchodził się z dziełami Teodora Parnickiego (na przykładzie cyklu Nowa baśń), czego świadectwem są dokumenty zachowane w Archiwum Akt Nowych. Teodor Parnicki (1908–1988) – polski prozaik, eseista, krytyk literacki, autor licznych powieści historycznych i fantastyczno-baśniowych, mimo iż do 1967 roku przebywał na emigracji, publikował w dużej mierze w Polsce, dlatego też wszystkie jego utwory – podobnie jak cała literatura wychodząca w oficjalnych krajowych wydawnictwach – były poddawane ocenie głównego Urzędu Kontroli Prasy, Publikacji i Widowisk, zatem cenzurze instytucjonalnej. Artykuł opisuje cenzorską historię trzech książek wydanych w cyklu – dwóch pierwszych z serii oraz drugiego wydania pierwszej. Główne zastrzeżenia urzędników kontroli skupiały się na sposobie opisu w powieściach kwestii żydowskiej.

Published: July 2023

W 1975 roku barcelońskie wydawnictwo Seix Barral wydało hiszpański przekład Kongresu futurologicznego Stanisława Lema. W następnych latach Lem wysunął się na czoło rankingu najczęściej tłumaczonych polskich pisarzy. Pierwsza część artykułu analizuje historię hiszpańskich wydań dzieł pisarza, podkreślając zasługi jego najwybitniejszej tłumaczki Jadwigi Maurizio. Druga część tekstu stanowi interpretację powieści Pokój na Ziemi, która – zdaniem autora (i tłumacza) – zasługuje na więcej uwagi ze względu na jej ładunek intelektualny i oryginalny typ bohatera-narratora.
„To mówię ja, który wierzę w powrót z wygnania”. Dziedzictwo i pamięć w autobiograficznej prozie Erwina Kruka
Authors:   Uniwersytet Warmińsko-Mazurski w Olsztynie, Szatrawski Krzysztof D.
Published: July 2023

Erwin Kruk (1941–2017), wybitny pisarz mazurski, autorytet moralny i działacz społeczny, obok poezji i prozy artystycznej pozostawił bogaty wybór eseistyki związanej z historią kultury mazurskiej. Szczególną pozycję w jego dorobku zajmuje Spadek. Zapiski mazurskie 2007–2008. Jest to zapis próby odzyskania majątku przejętego po śmierci rodziców na mocy dekretów obowiązujących po wojnie. Walka o odzyskanie domu okazuje się drogą do odzyskania pamięci rodzinnej, rekonstrukcji zdarzeń i dokumentów, które przywracają poczucie ciągłości rodzinnej i społecznej historii. Wartości artystyczne opowieści Kruka sprawiają, że wymowa zapisków wykracza poza konwencjonalne formy autobiografizmu, łącząc przekaz emocjonalny i intelektualny z zawartością symboliczną.
(W) rytm słabych podmiotów – Inni ludzie Doroty Masłowskiej jako wyraz nowego zjawiska kulturowego losers’ turn
Authors:   Akademia Górniczo-Hutnicza w Krakowie, Sadowska Martyna
Published: July 2023

Celem niniejszego artykułu jest analiza Innych ludzi Doroty Masłowskiej w perspektywie kategorii „porażki”, a dokładnie jej specyficznego wariantu, który określam mianem „przegrywu”. W swoim tekście pragnę skupić się na wizerunkach „człowieka przegrywa”, jakie – moim zdaniem – zaprezentowała w powieści Masłowska. Ponadto analizuję również szeroko pojęty rytm, z jakim mierzą się bohaterowie Innych ludzi (i nie tylko oni). „Musicalowa rap-piosenka” polskiej pisarki skłania też do refleksji dotyczącej szeroko pojętej „Inności”. Książka porusza problematyczne kwestie współczesnej rzeczywistości społeczno-kulturowej. Ponadto twórczość Masłowskiej dobrze odzwierciedla tezy i refleksje badaczy i badaczek, którzy próbują uchwycić zachodzące zmiany w obrębie dyskursów społeczno-kulturowych. Zakończenie niniejszego tekstu jest więc próbą przybliżenia tych poszczególnych projektów badawczych.
İDARE İLE KAMU MALLARI ARASINDAKİ HUKUKİ İLİŞKİ BAĞLAMINDA DEVLETİN HÜKÜM VE TASARRUFUNDA ALTINDA OLMA
Authors: IŞIKLAR Celâl
Published: July 2023

Hukukumuzda kamu mallarına ilişkin temel bir kanun bulunmamaktadır. Kamu tüzel kişilerinin üzerinde özel mülkiyet kurulmamış mallarına kamusal mal denir. Doktrindeki hâkim görüşe göre, idare ile kamu malları arasındaki üzerindeki hukuki ilişki kamu mülkiyeti ilişkisidir. Kamu mülkiyeti kamu hukuku kurallarından kaynaklandığından özel mülkiyetten farklıdır; ancak değişik ölçülerde de olsa onun gibi kullanma, yararlanma ve tasarruf yetkilerini içerir. Buna karşılık başta Anayasa (m.43) olmak üzere birçok kanunda “Devletin hüküm ve tasarrufunda” olma deyimi kullanılmaktadır. Bu deyim bazen sâdece belirli mal kategorilerini ifade etmekte, bazen de idarenin her türlü malını kapsamaktadır. Terimin mülkiyet öncesi bir denetim ve gözetim yetkisi anlamına geldiği de belirtilmektedir. DHvTA olma doğrudan Devletin belirli malları üzerindeki hükümranlık hakkını gösteren bir terimdir. Terim kamu hukuku kurallarının uygulandığı, kamu yararını sağlamaya yönelik, kamu malını hem birey ve topluluklara hem de Devlete karşı koruma garantisi veren bir kuralı içeren, özgül ve özgül bir kamu mülkiyeti ilişkisi demektir. DHvTA olma malın özel mülkiyete konu edilmesini mutlak surette yasaklamaktadır.

Miradas al vacío: la artificialidad de los discursos fundacionales. Hacia una lectura de Álvaro Enrigue
Authors: Sánchez Martínez Francisca
Published: July 2023

«¿Cómo es que hemos construido toda una épica si la Nación es un puro artificio?». Este es uno de los interrogantes que resuenan en la obra del mexicano Álvaro Enrigue, cuyas ficciones dejan al descubierto lo que de relato, de artificio, poseen los cimientos sobre los que se sustentan identidad y tradición. A través del análisis de dos de sus novelas, El cementerio de sillas y Muerte súbita, intentará mostrarse cómo el autor se sirve de recursos como la ironía, la parodia o la autoconsciencia para cuestionar la autenticidad de esos discursos de legitimación que ostentan el carácter de verdad única.Palabras clave: discurso, identidad, ironía, desmitificación

Diagnostic Challenge of Adult-onset Type 1 Diabetes Mellitus in a Remote Hospital
Authors: Hartono Bryan Arista , Henrina Joshua , Turmudzi Doddy M
Published: July 2023

Type 1 Diabetes Mellitus (T1DM) is a chronic endocrinological disease due to an autoimmune process. The prevalence of T1DM is 9.5% worldwide, with the incidence of 15 out of 100,000 people, ranging from childhood to 40 years of age. Autoimmunity-related late-onset Diabetes Mellitus (DM) patients could be diagnosed as classic T1DM or latent autoimmune diabetes in adults (LADA). A 30-year-old male patient with unremarkable previous medical history was admitted to the emergency room with dyspnea for the last three days that was worsened six-hour before admission. Physical examinations showed a body Mass Index (BMI) of 18.75 kg/m2, irregular pulse, and Kussmaul breathing. The patient was diagnosed with diabetic ketoacidosis (DKA) on May 23, 2019. He was discharged with subcutaneous insulin pen injections. Two years later, he was readmitted with DKA due to discontinuing his treatment. He stated that the reason for stopping the insulin was because he was tired of injecting it. The patient was hospitalized and was discharged with oral antidiabetic agents to cope with his injection tiredness issue. One week later, the patient complained of dyspnea and was diagnosed with recurrent DKA. He was hospitalized and prescribed subcutaneous insulin. In this kind of situation, a diagnosis of LADA for patients presenting with DKA without prior history of DM in early adulthood needs to be considered. In contrast to the classic T1DM, the need for insulin occurs late in LADA. Affordable and widely available ancillary examinations are needed, including in remote hospitals. Finally, motivational support for patients is as important as the pharmacological treatment since lifelong insulin injections are needed.
Lexis and Phraseology of the Ukrainian Official-Business Language in the Dictionaries Published During the 20th – the Beginning of the 21st Centuries
Authors:   The Ukrainian Language Institute of the National Academy of Sciences of Ukraine, Kyiv, Ukraine., Boiarchuk Olena
Published: July 2023

In the proposed monograph dynamic processes in lexis and phraseology of the Ukrainian official-business language during the 20th – the beginning of the 21st centuries were outlined on the material of the 37 dictionaries. The register formation principles of the Russian-Ukrainian common language dictionaries and official-business and law language dictionaries were ascertained. The main tendencies of official-business lexis development during the stated period were defined. There was performed the comparative analysis of the lexemes and phraseological units given in the selected dictionaries. The most frequently used in the official-business communication lexical-semantic groups of derivatives from the roots –вер-, –рук-, –вѣд-, –яв– were distinguished. There was given consideration to the variability in usage of the key terms. In particular, specific examples demonstrate the mechanisms of Russification of the Ukrainian official-business vocabulary, which were used in the 30s–80s of the 20th century. Despite the fact that a significant part of the modern Ukrainian official-business lexicon is made up of borrowings from the Russian language, recently the tendency to form official-business terminology on the original Ukrainian basis has been more and more developed in Ukrainian lexicography. In an effort to exclude from business terminology lexical and grammatical elements alien for the Ukrainian language, lexicographers now refer to the works of linguists of the 1920s – one of the most productive periods in the history of Ukrainian lexicography. The author argues that the use of the experience and achievements of linguists of the early twentieth century is a necessary condition for the normalization of the business language at the present stage of its development. To visualize the dynamic processes in the official-business lexis during the stated period comparative tables were made. The standardization advice for the official-business dictionaries’ compilers was given. The book is intended for lexicologists, dictionary compilers, university professors, philologists, and all those interested in the history of the Ukrainian language evolution.

Este ensaio objetiva discutir a representação da água como fonte na qual bebem as poetisas, examinando as categorias de água bachelardianas nos sonetos retirados da obra de Florbela Espanca e Gilka Machado. Para o efeito, e de modo a instaurar uma leitura dialógica fundamentada entre os sonetos das duas autoras, recorreu-se, para alicerçar o quadro teórico, ao estudo de Gaston Bachelard (1989), assim como aos estudos de Gilbert Durand (2012) e de Joke J. Hermsen (2022). Por outro lado, a bibliografia passiva levou em consideração os poucos estudos que, até agora, tangenciaram este tema e, por isso, a nossa preocupação será a de aprofundar a imagética aquática nas escritoras em apreço.
Altas capacidades en adultos
Authors: Rodrigues de Souza Colozio Amanda , Rosselló Mayans Elena , Borges África
Published: July 2023

En los estudios más recientes en altas capacidades se señala la importancia de identificar para atender las necesidades educativas. De esta manera, después del proceso de identificación, hay que proporcionar una respuesta educativa, a través de un programa de enriquecimiento intraescolar, o sea dentro de la escuela, o extraescolar, fuera de la escuela.  Así, la presente investigación tuvo como objetivo, en primer lugar, analizar quién diagnosticó la alta capacidad en los participantes, en según qué edad recibió un diagnóstico, y en tercer lugar, qué respuesta educativa recibió durante la vida escolar. La investigación fue descriptiva con análisis cualitativo. El cuestionario fue contestado por 217 adultos con altas capacidades. Así, se ha podido comprobar que más de la mitad de los diagnósticos recibidos proceden de Mensa (50,6%), seguidos de psicólogos (25,8%) y de los centros educativos o psicólogos escolares (11%). Acerca de las edades, 80% de la muestra fue diagnosticada con altas capacidades en la edad adulta, destacando las edades entre 21-25 años, seguidos de 31-35 años y 26-30 años. En ese marco, cabe enfatizar que sólo 17 participantes (7,9%), recibió algún tipo de respuesta educativa durante su vida escolar. Estas respuestas se dividieron en respuestas intraescolares, extraescolares y para adultos.  Sin embargo, los resultados son alarmantes, ya que muestran la invisibilidad de estas personas en cuanto a una identificación y respuesta educativa en la enseñanza básica. Esto provoca, que la ausencia de evaluación e intervención temprana puede no ofrecer propuestas y cuidados diferenciados que puedan satisfacer las necesidades específicas de desarrollo de la persona con altas capacidades, lo que puede conducir a la inhibición de su potencial.
Was the Tale a Women's Genre? Tellers, Collectors, and Writers of Tales in 19th-Century Hungary
Authors: Gulyás Judit
Published: July 2023

In 1858 a leading Hungarian literary critic as well as collector and editor of folk poetry started a debate about the possible literary career of women, arguing that literature and other forms of public artistic activity are fields that should not be open to women as it may cause serious moral and social problems. Yet, he noted that in case women still insist on becoming literary authors, they should turn only to certain genres, such as tales. The article investigates how the tale became a gendered genre, and presents women tellers, collectors and writers of tales as well as the diverse ways they were represented in Hungarian culture in the 19th century.
A Healthcare Chaplain’s Guide to Mental Health Chaplaincy for Geriatric Patients in the United States
Authors: Gopaul Margaret T , Martinelli Deena A
Published: July 2023

The US Department of Veterans Affairs (VA) and the US Department of Defense (DoD) evaluated the expanding roles of chaplains in mental health and identified a prevalent need for additional training among healthcare chaplains. The literature revealed that chaplains were lacking the skillsets needed to effectively care for patients with mental health disorders. A gap remains in the literature regarding the reported level of mental health training and preparedness of chaplains who minister to geriatric patients with mental health disorders. This quantitative study used a questionnaire instrument to survey 26 chaplains in the United States. The participants were experienced healthcare chaplains working in New York, New Jersey and Connecticut. The findings confirmed the need for additional training and preparedness among chaplains who minister to geriatric patients with mental health disorders. The results and empirical literature informed the development of a practical guide that includes ways to meet these challenges and assist chaplains in providing comprehensive delivery of competent care to patients.

Published: July 2023

High sulfate content in seawater forms sulfate salts, which become impurities in sea salts.  This study investigates the influence of lime juice in the adsorption of sulfate ions in seawater using commercial activated carbon. A full factorial experimental design was employed to optimize the level factors of activated carbon type, adsorbent dosage, and concentration of lime juice in response to the percentage reduction in sulfate concentration. Activated carbon (GCB) and acid-washed activated carbon (GCA) were two types of coconut shells granular activated carbon used for the experiment without further modification. The main effect and interaction effects were analyzed using analysis of variance (ANOVA) and p-values to define the influence of variables affecting sulfate ions adsorption. The adsorption of sulfate ions in seawater was affected by the interaction between the activated carbon type and the dosage, and the concentration of lime juice. The lime juice factor significantly enhanced the performance of activated carbon to adsorb the sulfate ions in seawater, and the factor's contribution was 58.2 %. The optimum sulfate ions reduction from seawater was attained at levels of factors activated carbon GCB, the dosage of 50mg, and the concentration of lime juice 50 µl. The interaction between lime juice and activated carbon pores are electrostatic. The impurities are attracted by the revealed polarity of the activated carbon pores. High electronegativity of lime juice acid pulls the negatively charged ions of the impurities. The more economical activated carbon, GCB, which performed better in sulfate ion adsorption, provides an alternative for reducing sea salt impurities. Hence, GCB can directly be mixed with the seawater to produce high quality sea-salt. Therefore, this study is suitable to improve sea salt product quality that processed with activated carbon

The research of the influence of teff flour on the technological process and quality of wheat bread was present in the article. The analysis of the chemical composition of teff flour indicated, that it is a valuable raw material for enriching wheat bread. However, its dosage in the quantity of 10 and 20 % to the weight of wheat flour leads to decrease in the amount, springy and extensibility of gluten in the dough. Alveograph studies also confirmed that dosage of 20 % of teff flour the most decreases springy of the dough and it becomes more plastic.
The improvement of the structural and mechanical parameters of bread with teff was applied the biotechnological method of preparation on sourdough that created on the pure cultures of lactic acid bacteria “Biolight”. The experimental studies were proving that utilizing of teff flour in the quantity of 10 % and sourdough improved both the quality and nutritional value of wheat bread. In particular, the specific volume of bread increased by 4.0 %, acidity ‒ by 2.9 % compared to the control; and the product was distinguished by a pleasant "nutty" taste and aroma. Close correlations between the percentage of teff addition and the spread of the dough ball were established, r=0.98 (n=10, p≤0.05) and the form stability of the bread, r=(‒0.95) (n=10, p≤0.05). It allowed establish that wheat bread with teff addition need to make in the mould.
It was calculating that consumption of the daily norm of bread with 10% teff the consumer will be receiving a sufficient quantity of valuable food nutrients. Thus, the need of protein was covered by 42.9 and 49.8 %; iron ‒ by 32.3 and 28.5 %; vitamin B5 ‒ by 17.6 and 24.2 %, respectively, for men and women; and the need for phosphorus ‒ by 26.7 %, for both groups.
The technology of wheat bread with teff of high quality for mass consumption that recommended for wide industrial implementation has been develop

The object of research is the technology of creamy-whipped sweets with the addition of fruit and berry paste. Its addition solves the problem of improving sugar masses, namely structural characteristics and physiological value (enrichment with non-starch polysaccharides, vitamin C, polyphenols, and organic acids). In addition, a positive effect is achieved by providing the products with original organoleptic properties without the use of synthetic dyes and flavors. The proposed fruit and berry paste is obtained at gentle temperatures, which allows preserving the biological potential of raw materials and is characterized by a strong structure with a dynamic viscosity of 498 Pa·s.
It was found that the introduction of fruit and berry paste in the amount of up to 10 % by weight of formulation raw materials improves the foaming ability of protein mass in the process of whipping. Increasing the paste content to 20 % leads to a slight deterioration in this indicator, but its value is at the level of control. The stability of the whipped protein mass increases evenly by increasing the dosage of the additive. The positive effect of fruit and berry paste on the quality indicators of finished creamy-whipped candy masses was noted. Samples with the additive give less shrinkage during the structuring process, its duration is reduced, and strength increases. It is recommended to add fruit and berry paste to creamy-whipped candy masses in the amount of 15 % of the total amount of formulation raw materials and at the same time reduce the formulation dosage of agar by 40 %. Such products acquire an original lilac color, a pleasant yogurt flavor, and the aroma of red currant. The nutrient composition of products is significantly improved – the content of non-starch polysaccharides increases by 2 times; the product is enriched with vitamin C and polyphenolic compounds that are absent in the control sample

Published: July 2023

This paper investigates tendencies in the development of information and communication technologies for studying consumer behavior in the process of brand management. Trends in consumer behavior have been identified – strengthening environmental awareness and ethics, spreading e-commerce, increasing mobile experience, strengthening the role of personification, etc. The influence of changes in consumer behavior on the process of positioning and promotion of brands was substantiated. The expectations and actions of consumers and directions of the process of brand management as a result of transformation of consumption were characterized. Attention is focused on the role played by information and communication technologies in the study of consumer behavior in the process of brand management. The basic tools by types of information and communication technologies were systematized. It was determined that the main type of information and communication technologies, due to which a high degree of personalization is ensured, are social networks. In addition, technologies for analyzing web data, e-mail, mobile device data were used to study consumer behavior. A three-dimensional model of studying consumer behavior in the process of brand management has been proposed, which takes into account the components of consumer behavior, which needs to be investigated, the stage of the brand's life cycle, technologies for studying consumer behavior. A matrix of choice of appropriate information and communication technologies for studying consumer behavior at different stages of the brand life cycle has been formed. The practical use of the proposed methodological approach will provide more reliable information on various components of consumer behavior. This could create prerequisites for developing an effective strategy for positioning and brand promotion

The object of the study is the period of induction of accelerated oxidation of oil solutions of fat-soluble dyes chlorophyll and beta-carotene. The effect of the content of fat-soluble dyes on the period of induction of accelerated oxidation of their solutions in refined sunflower oil was studied. The peculiarity of the work consists in establishing approximate graphic and mathematical dependences of the term of the induction period of accelerated oxidation of refined sunflower oil on the content of chlorophyll and beta-carotene separately and together. This is important for predicting the shelf life of oil solutions of fat-soluble dyes.
It was determined that chlorophyll A practically does not show a pro-oxidant effect if its content is up to 0.05 g/l. The content of chlorophyll A at the level of 0.10 g/l leads to a reduction in the duration of the induction period by 14 %; 0.20 g/l – by 36 %; 0.30 g/l – by 48 %. The content of beta-carotene at the level of 0.10 g/l leads to an increase in the duration of the induction period by 35 %; 0.20 g/l – by 47 %; 0.30 g/l – by 54 %. The content in the oil system of 0.10 g/l of beta-carotene and 0.05 g/l of chlorophyll A leads to a reduction in the period of induction of accelerated oxidation by 8.4 % compared to the oil solution of 0.10 g/l of beta-carotene without chlorophyll A. The obtained data are explained by the fact that there is a compensatory effect of the antioxidant beta-carotene on the pro-oxidant effect of chlorophyll A in the oil solution. A feature of the obtained results is the possibility of predicting the shelf life of oil solutions of fat-soluble dyes. From a practical point of view, the results of the research allow to develop oil systems taking into account the separate and compatible features of reactivity to the oxidation of chlorophyll and beta-carotene. An applied aspect of using the scientific result is the possibility of expanding the assortment of oil products of increased nutritional value with different contents of chlorophyll and beta-carotene

Evaluating the effectiveness of the implementation of an investment project is a key issue when making management decisions both at the stage of setting up a startup and for expanding an existing business.
This paper reports a systematic approach to building a mathematical model to solve the task of forecasting the effectiveness of business projects, taking into account the influence of factors of the external economic environment. Proposed factors include the impact of supply and demand on the price of goods, political and industry risks, the volume of commodity supply and sales. In view of this, a method for calculating the political component of the discount coefficient using the Fourier series has been proposed. Using the theory of differential equations, correlation and regression analysis, a mathematical model for forecasting indicators of efficiency of business project implementation taking into account the influence of factors of the external economic environment has been constructed. Based on it, a generalized algorithm for applying a mathematical model to predict the effectiveness of investment projects in various business sectors has been developed.
The results from applying differential equations and variable discount coefficient showed a decrease in NPV by 14 %, and PI by 5.1 %, due to more accurate consideration of the political component in calculating the discount factor. Also, with the influence of supply and demand on the price of goods and nonlinear cash flows, it was found that the payback period does not clearly indicate the effectiveness of the implementation of an investment business project. Determining these factors provides more accurate information to the investor or business owner when forecasting the stability of a business project for making management decisions on its implementation

One of the most common types of AC electric machines are asynchronous electric motors. Because of their simple and reliable design, they are used in many industries. In this paper, the object of research is an asynchronous electric motor with a short-circuited rotor. To ensure the normal operation of an asynchronous electric motor, the heating temperature of its active parts should not exceed the maximum permissible values, which are determined by the corresponding class of heat resistance of the insulation system used in the electric motor. In asynchronous electric motors, the stator winding is the most thermally vulnerable node, which is the first to fail when the temperature of the electric motor increases. Thermal protection devices protect an asynchronous electric motor from emergency operating modes accompanied by an unacceptable excess of the temperature of their windings.
In order to build an indirect system of protection against overheating of the stator windings, a temperature observer has been developed using already available signals in a frequency-controlled electric drive. Simulation studies were performed in Matlab/Simulink application software packages. Simulation studies were carried out on the basis of asynchronous electric motors of the 4A series with a capacity of 30, 75 and 110 kW in the temperature range from 20 °C to 250 °C. As a result of the research, it was found that the error of indirect calculation of the temperature of electric motors, taking into account the correction factor, does not exceed 1 %. The proposed temperature observer can be used to build protections for asynchronous electric drives

Accidents while working in the construction industry source many tangible and intangible losses. Although various measures have been taken to reduce occupational accidents in the construction sector, occupational accidents are still increasing, especially in Indonesia. Meanwhile there is some literature on the relationship between personality traits and accidents, much remains to be considered before applying the research to accident prevention. Therefore, there is a need to study in detail the correlations between the Big 5 characteristics and safety behaviors, including other variables, so that preventive action can be taken as a form of occupational injury prevention. The purpose of this study was to analyze the impact of the Big 5 personality traits, using personal values and safety culture as variables influencing safety behavior in construction workers. This study analyzes or resolves not only the direct impact of Big 5 personality traits on safety behavior of construction workers, but also the indirect impact through personal values and safety culture. Data were collected through interviews with 300 construction workers in Surabaya, Malang and Batu, East Java, Indonesia. The results showed that the Big 5 personality had a significant positive impact on workplace safety behavior with a difference of 0.299. In addition, personal values and safety culture as intervention variables may influence the impact of Big 5 personality traits on workers' safety behavior. The 0.788 and 0.545 Big 5 personalities have a significant impact on personal values and safety culture. One of the dominant indicators when measuring the Big 5 personality structure is neuroticism, with the highest stress factor of 0.928. Therefore, if management wants to improve worker safety behavior, it should conduct a workplace analysis to hire competent workers with a high degree of neuroticism

The object of research is the operator of a mobile fire installation; the subject of research is the operator’s characteristics, particularly his reliability. The method of determining the reliability of a mobile fire installation operator as a functional element of a dynamic system is substantiated. Operator failure is interpreted as the output of its frequency characteristics beyond permissible limits. Analytical dependences for variations of the operator’s frequency characteristics on variations of its parameters – transmission coefficient, delay time, and time constant are constructed. The amplitude and phase reliability of the operator of a mobile fire installation are determined using the Laplace functions, the arguments of which are the permissible values of variations in the frequency characteristics of the operator and variations of its parameters. Determination of variations of operator parameters is carried out by the instrumental method using the operator’s activity monitoring system. The test effect on the operator of a mobile fire installation is carried out in the form of a rectangular pulse that formalizes the change in the position of the combustion cell at a priori a given distance over a priori predetermined time. A signal characterizing the operator’s response to the test impact is determined using the Laplace integral transform. Measuring the parameters of this signal allows you to determine the variations in operator parameters that are used to determine its reliability. It is shown that for variations of operator parameters, the values of which are 10.0 % with RMS deviations of 3.3 %, with a probability of 0.8715 the amplitude-frequency and phase-frequency characteristics at the time of its control will not differ from their nominal values by more than 5.0 %. The requirements regarding the reliability of the operator’s activity control system are determined
Construction of a mathematical model and approximate analytical solution to the problem of energy exchange in the «sun ‒ paraboloid concentrator ‒ heat receiver» system

Published: July 2023

The object of research is the processes of radiation transfer in the «Sun – paraboloid concentrator – heat receiver» system. There are many factors that affect the value of the density of the concentrated heat flux that reaches the surface of the heat sink. The study of the influence of these factors on the overall energy indicators of the system is an important scientific problem that was solved in this work. To solve this problem, a generalized mathematical model of the radiation transfer process in the «Sun – concentrator – heat receiver» system was built, which was adapted for a paraboloid concentrator. The constructed mathematical model was solved by an approximate analytical method, which took into account the integral and discrete parameters of the system, as well as the probability distribution of aberrations of the concentrator surface, its defocusing, and other random influences. The dimensionless density of the heat flux on the surface of the heat sink for a mathematically ideal and real paraboloid concentrator of a fixed geometry was determined. Using the found analytical solution, the results obtained on the basis of the Monte Carlo method were verified. Analytical and numerical results for a mathematically ideal and a real concentrator with minor aberrations and a clear orientation to the Sun agree within the permissible error. For a real concentrator with defocusing, a deviation of numerical data from analytical data was observed. The presence of deviations is associated with a simplification in the interpretation of the analytical probability distribution, in which it is impossible to take into account each influence separately. The obtained analytical results will be useful in the development of real power plants and can be used practically at the stage of checking the adequacy of the system model

The dairy industry must focus on sanitation and hygiene requirements to ensure product safety, control of detergents, tanks, pumps. Compliance with these requirements will provide conditions for the production of a high-quality dairy product, maintenance of technical and mechanical frequency at the enterprise, and prevention of the reproduction of harmful bacteria. Under these conditions, the problem of cleaning technical equipment from harmful residues on site is urgent. The object of the study is the basic processes in the Cleaning-In-Place system in the dairy industry. It is recommended to design a human-machine interface for on-site cleaning in the Siemens WinCC Flexible software. It is worth noting that the proposed interface takes into account the reduction of equipment downtime during the washing of technological equipment, a convenient user interface, and ease of maintenance. The state of use of existing visualizations of on-site cleaning interfaces that do not use simultaneous washing of two tanks with cleaning solutions (alkaline and acid) and the state of controlled values in selected washing lines were evaluated. Numerical evaluations of the results use modern programming technology and high information productivity of the user interface. A human-machine interface was designed with the possibility of parallel cleaning of two tanks at different ends of the workshop and the selection of recipes for different groups of tanks. This interface displays emergency messages, the status of the washing process of production lines and control based on data from sensors. The practical use of the obtained scientific results is that the designed interface can be used not only in the dairy industry but in any other food industry

Published: July 2023

Software design uses the set of tools for building and analyzing models which do not allow solving the complex problem of improving the quality of design solutions. This task includes not only the synthesis of the software model with parallelism, the detection and localization of errors for the correction of the model, but also the visual analysis of the model for the synthesis of new or corrected design solutions. The study object is the building and analyzing processes of software models with parallelism.
Techniques and a method‘s of synthesis and analysis of the software model with parallelism are proposed, which are based on the combined approach to simulation modelling of the systems with parallelism. The analysis of the software model with parallelism begins at the stage of creating and static analyzing component models. The proposed method provides dynamic analysis of component models and partial model in the process of assembling the complete software model.
Building of component models is carried out based on the rules for building PN-models, PN-templates and the principle of structural similarity, while their static properties are checked. The dynamic analysis of the component models of software is carried out using simulation modeling and the method of invariants. In process of the model assembling, the complete model is gradually formed by assembling it from the models of software components, and its dynamic properties are analyzed. In this case, the convolution method, the method of invariants, and simulation modelling are used.
Through in-depth dynamic analysis the presented method‘s provides an opportunity to check the static and dynamic properties of the studied models, which ensures an increase in the quality of project solutions at the software design stage. It can be used to reduce the cost of software development, as well as to analyze the developed software to improve the efficiency of support
