Representación de la alteridad y temáticas de la itinerancia en la autoficción gráfica entre ici et ailleurs de Vanyda Savatier
Authors: Soto Ana Belén
Published: November 2023

Pensar las posibilidades del retorno en la narrativa francófona contemporánea implica cuestionarse sobre la isotopía temática del desplazamiento desde una multiplicidad de perspectivas. En este sentido, es preciso detenerse en el corpus de escritores representativos de las xenografías francófonas en la Europa actual, ya que a través de una pluralidad de relatos basados en la experiencia vivida exponen reflexiones intrínsecas a la construcción identitaria en las sociedades de hoy. En este contexto, analizar la autoficción gráfica Entre ici et ailleurs publicada por Vanyda Savatier en 2016, permite detenerse en el epicentro reflexivo de este monográfico: las consecuencias de la experiencia del retorno (im)posible.
Reescrituras variopintas del mito de don Quijote en la publicidad: el turismo, la lotería y el vino
Authors: Pierre-Louis Marie Cadette
Published: November 2023

El principal objetivo de este trabajo es analizar las reescrituras del mito de don Quijote en anuncios provenientes de tres campos: el turismo, la lotería y la enología. La metodología elegida para este trabajo es la mitocrítica. Al respecto, hemos retomado los principales mitemas que ha establecido Bautista Naranjo (2015a). También hemos añadido otro mitema que permite incluir el modelo narrativo del Quijote como parte del mito de don Quijote. Tal como requiere la mitocrítica, los anuncios figurados en el artículo han sido analizados en comparación con el relato fundador del mito de don Quijote, Don Quijote de la Mancha (1605, 1615) escrito por Cervantes.
Okos stadionok – Hogyan reformálja a digitális ökoszisztéma a
sportinfrastruktúra üzemeltetését és a sportszolgáltatások modelljét
Authors: Molnár Anikó
Published: November 2023

A stadionok alapvetően befolyásolják sportesemény vonzerejét, hiszen
a létesítmény és a kapcsolódó kiegészítő szolgáltatások is jelentősen
hozzájárulnak a fogyasztói érdeklődés növeléséhez, így azok fejlesztése és
üzemeltetése közvetlenül és közvetetten is hozzájárul a szcéna meghatározó
bevételi forrásainak növeléséhez. A mai stadionok egyre erősödő versenyben
vannak az otthoni megtekintés lehetőségeinek fejlődése miatt, melyek jobb
alternatívát nyújtanak a mérkőzést követni kívánó tömeg számára. Az erősen
digitalizálódó világ olyan technológiai megoldások tárházát nyújtja,
amelyek a stadionok különböző aspektusainak augmentálásával versenyelőnyt
jelenthetnek a fogyasztók érdeklődésére irányuló kiélezett versenyben. Az
utóbbi évek legújabb fenoménja az okos stadion, az üzemeltetésbe integrált
okos eszközökkel és a digitalizáció, illetve a felhő alapú rendszerekkel a
mérés olyan mértékű megújulását eredményezte, amely gyökereiben változtatja
meg a sportszolgáltatások menedzsmentjét és amely a stadion és az azt
körülvevő tér minden egységére kiterjed, így javítva a fogyasztói
élményeket vagy éppen a hatékony létesítménygazdálkodást.

Authors:   Crisis and Emergency Management: Theory and Praxis, Park Soyoung , Kim Yunyoung , Seo Eun Young
Published: November 2023

This study aimed to assess the levels of depression, suicidal ideation, and self-related health among elderly individuals and analyze the mediating effect of self-related health in the relationship between depression and suicidal ideation. The study surveyed 330 elderly individuals residing in G city. Data analysis was performed using multiple regression with SPSS 27.0 Statistics Program. The research findings indicated that factors influencing suicidal ideation among the elderly included being female, residing in rental housing, being a non-smoker, having higher levels of depression, and lower levels of self-related health. Depression among the elderly was found to be higher among females, those aged 80 and above, those living in rental housing, and those with a perceived poorer economic status. Based on these results, the study suggests prioritization in elderly depression treatment according to the mental health status and socio-economic conditions of individuals and proposes multifaceted and proactive suicide prevention interventions that take into account such factors.

Published: November 2023

Differential mode of processing GNSS in the preferred choice for high precision assignments in areas where there are active reference stations. Studies into the performance of these continuously operating reference stations (CORS) have mainly been centered on either session times or baseline lengths. Active CORS have emerged replacing the old passive stations. However, these innovations in the science of spatial data acquisition needs to be monitored for networks strength and sensitivity. In this study, GPS data from five CORS stations for 12 days were used and processed with RTKLib. The research was restricted to baseline lengths of 2.5 to 13.5 km with varying session lengths starting from 1 hour to 24 hours. 3D error for each baseline and 3D RMS for each group of baselines were subsequently computed. A plot of the results was analyzed and compared. This comparison reveals that Geodetic accuracy (below 1cm) is achieved after 4 hours of observation session showing that the precision of Rtklib baseline solution can reach sub-centimeter level and therefore can yield reliable results in almost any professional project.
Language ideology, policy and classroom practices in Oshiwambo speaking areas, Northern Namibia
Authors:   University of Namibia, Iipinge Kristof , Banda Felix ,   University of the Western Cape
Published: November 2023

The study problematized language ideologies and policy to explore the efficacy of using English as the Language of Learning and Teaching (LOLT) among Oshiwambo speaking learners in the Omusati region of Northern Namibia. Focus group interviews with ESL teachers, interviews with the English Head of Departments (HODs), classroom observations and informal chats with the grade 12 learners were carried out at six secondary schools. The study finds that students struggle to partake in meaningful classroom interaction and to comprehend instruction and content in English. Although students may express themselves better in Oshiwambo, they are not allowed. Some ESL teachers would use Oshiwambo to maintain order in class, but avoid using Oshiwambo to help struggling learners believing this would negatively impact learners’ English proficiency. Some ESL teachers were also found to blame ESL content subject teachers for learners’ poor English proficiency, as they used Oshiwambo in class to teach and explain content. We conclude that ESL classroom practice is teacher-centred by default, and students are muted as they find themselves with no voice to express themselves efficiently and efficaciously, and deaf to classroom content delivered in an unfamiliar language, English

Authors: M Mohan Tej , Rao Mahabaleshwara , K Shivananda Bhat
Published: November 2023

Accessing the library’s subscribed electronic resources remotely by users has always been a challenge for the library. KMC Health Sciences Library, Manipal relied on proxy-based authentication to remotely cater its e-resources to library users. To enhance the secure usage of electronic resources and to provide user-friendly authentication, the library has considered a Single Sign-On (SSO) remote access through OpenAthens. The article demonstrates the setup process of OpenAthens and the various steps involved in the transformation of the library from proxy-based authentication. The single sign-on setup at the library has benefited users in having a single set of credentials to access all the library e-resources, reducing the hassle of remembering multiple login credentials. Features such as cloud hosting, granular usage reports, and the admin dashboard gave complete hold on the usage of library e-resources. Although OpenAthens has its merits, the setup process involved challenges in the integration of existing library-subscribed e-resources. This article provides insight into the step-by-step process of enabling OpenAthens, addresses troubleshooters, and makes recommendations to libraries looking towards SSO remote access.

Investigation of Plant Surfaces with Environmental Scanning Electron Microscopy (ESEM®) - A Comparison with Conventional SEM
Authors: Kolb Dagmar , Stabentheiner Edith
Published: November 2023

Environmental scanning electron microscopy (ESEM) enables the investigation of untreated and watercontaining material without preparation with the benefit of SEM (depth of focus and three dimensional imaging of surfaces with a high resolution). Conventional SEM (CSEM) usually requires time consuming fixation, drying and coating of samples. Their surface structures may be altered by this procedure. For comparison a large number of plant samples was observed with both methods. Using CSEM, secretion products or mucilagineous coatings may be removed and dynamic processes cannot be observed. However, the samples can be investigated several times. In contrast, ESEM allows the observation of watercontaining, native surfaces and this method is the only possibility to watch dynamic processes in the SEM. However, using ESEM the plant material is very sensitive to beam damages because of the lack of the protecting metall layer - necessary for non-conducting surfaces in CSEM and dehydration cannot be prevented completely. In summary, ESEM will not compete with CSEM but it will establish oneself as a valuable and essential supplement in studying plant surfaces.

Published: November 2023

The distribution and propagation of Zucchini yellow mosaic virus (ZYMV) within Styrian pumpkin plants (Cucurbita pepo L. subsp. pepo var. styriaca GREB.) was studied for one week starting 6 hours after ZYMV-inoculation using transmission electron microscopy (TEM). By negative staining, virus particles were found within the cotyledons and its petioles four days after the inoculation and within the whole plant seven days after the infection. Two weeks after ZYMV-inoculation the cytoplasm of infected leaf and stem cells showed typical features of ZYMV like cylindrical inclusions and proliferated endoplasmatic reticulum. No ZYMV-induced modifications were found within root cells.
The life of plants under extreme CO2
Authors: Vodnik Dominik
Published: November 2023

Higly elevated and fluctuating CO2 concentrations at the sites with geogenic CO2 enrichment create unique and often extreme gaseous environment for plant life. In our paper we review the knowledge on plant performance at mofette Stavešinci, which is known for very pure exhalations of CO2. The responses of root processes and those occurring in aboveground parts of the plants are presented and discussed. The primary target of elevated CO2 at NCDS are root- and other belowground processes, while the direct effects on shoots are expected to be minor and only periodical. The successfullness of plants to cope with adverse conditions can be largely dependent on inherent adaptive mechanisms, which can, however, not be regarded specific for the response to elevated CO2. Some species, for example cockspur grass (Echinochloa crus-galli), posess various mechanisms that make them fairly tolerant to extreme mofette environment.

Różnice we wdrażaniu zasad promocji zdrowia w szkołach w czasie pandemii COVID-19. Rozważania oparte na badaniach przeprowadzonych wśród dyrektorów polskich szkół
Authors: Leksy Karina
Published: November 2023

During the coronavirus pandemic, health promotion became crucial for preventing COVID-19 disease and mitigating its consequences. Implementing health promotion principles was particularly essential in educational settings, where the possibility of infection was high. Simultaneously, only limited empirical studies have addressed school principals’ perspectives on implementing health promotion issues during the COVID-19 pandemic. Thus, this study aims to examine the differences in implementing health promotion principles in schools during the COVID-19 pandemic. The results come from an online cross-sectional survey conducted in eight provinces of Poland from June to December 2021. The study was part of a global school principal health literacy survey under the COVID-HL Network. Research results have shown that schools in the Health Promoting Schools network tend to implement the whole-school approach to health more often. In addition, the longer the school belongs to the network, the more health promotion activities are implemented. It can be assumed that school principals play a crucial role in implementing health promotion principles in schools. Therefore, their health awareness and interest in health matters are essential for effectively promoting health in schools.
Stoici e Peripatetici su agire, patire e movimento: la testimonianza di Simplicio
Authors: Nastasi Giuseppe
Published: November 2023

Simplicius’ Commentary on Aristotle’s Categories contains the most extended testimony about the Stoic conception of acting (ποιεῖν) and undergoing (πάσχειν). Simplicius ascribed to the Stoics the idea that acting and undergoing are to be reduced to the movement. To this opinion Simplicius opposed the Aristotelian view according to which acting and undergoing are two different categories. In this paper I intend to outline the original Stoic position comparing the reportage of Simplicius with other Stoic sources. Later, I will deal with Boethus’ defense of the distinction between the categories of acting and undergoing. I will argue that Boethus directly reacted against the Stoic opinion reformulating it in Aristotelian language.
Further research results on confusion coefficient of Boolean functions
Authors: Liu Zhenyu , Zhuo Zepeng
Published: November 2023

The notion of confusion coefficient (CC) is a property that attempts to characterize the confusion property of cryptographic algorithms against differential power analysis. In this article, we establish a relationship between CC and the transparency order (TO) for any Boolean function and deduce some relationships between the sum-of-squares of CC, signal-to-noise ratio, and TO. We also give a tight upper bound and a tight lower bound on the sum-of-squares of CC for balanced s-plateaued functions. Finally, the results generalized a lower bound on the sum-of-squares of CC of Boolean functions with the Hamming weight k.
The anatomy of specialized knowledge: Comparing experts and non-experts through associations, frames and language models
Authors: Vintar Špela , Saksida Amanda
Published: November 2023

We explore specialized knowledge and aim to show that expert conceptual spaces differ from those of non-experts. This rather broad research question is addressed from different perspectives: first we collect free associations to selected stimulus terms from the domain of karstology from experts and non-experts, demonstrating that the underlying knowledge affects the associative inventory and that the overlap between both groups is low. Next, we look for knowledge frames which might shape the expert responses by activating conceptual links, and compare them to corpus-derived frames. Finally, we train neural language models on specialized versus general corpora to see whether the neural semantic space as represented by the cosine distance resembles the semantic spaces obtained through human associations. Results show that human associations indeed reflect knowledge frames, but that the overlap with the trained word embeddings is again low, indicating inherent differences between the associative semantic proximity in experts and non-experts, and between humans and neural meaning representations.
Natural probiotics improve heritable sterility
Authors: Ewe Chee Kiang , Rechavi Oded
Published: November 2023

Disrupting the small RNA pathway and chromatin‐modifying enzymes in C. elegans often leads to a mortal germline (Mrt) phenotype, characterized by progressive sterility observed over multiple generations at elevated temperature. This phenotype arises from the inheritance of aberrant epigenetic memory across generations. In this issue of EMBO Reports, Frézal and colleagues reported that, while in standard laboratory environment C. elegans wild isolates exhibit the Mrt phenotype, sterility does not occur when the worms are exposed to naturally associated bacteria and microsporidia. Excitingly, diet‐induced epigenetic memory may persist for multiple generations. This suggests intriguing diet–gene interactions in modulating nongenetic inheritance, potentially shaping the evolutionary trajectory of the animals.
The influence of the structure of guard rings on the dark currents of silicon p-i-n photodiodes
Authors: Kukurudzіak M.S.
Published: November 2023

The article examines the influence of the guard rings (GR) system structure on the dark currents of responsive elements (RE) and the actual guard rings of silicon 4-element p-i-n photodiodes (PD). The samples were made on the basis of p-silicon by planar technology. Samples with one, two, and three GR were produced. It was found that increasing the amount of n+-GRs does not reduce the dark current of the REs. But with an increase in the number of n+-GRs, the probability of an edge breakdown of the n+-p-junction in the regions of the exit of the hetero-junction of the GR to the surface increases. It is possible to reduce the levels of dark current of REs and GR by combining n+- and p+- guard regions, where p+-GR is a region of restriction of dark current leakage channels, isotypic with the substrate material. PD was made with p+-GR on the periphery of the crystal in the form of a concentric ring, as well as with a p+- region on the entire periphery of the crystal. This makes it possible to reduce the level of of dark current of n+- GR due to the reduction of the area of collection of charge carriers from the surface. But a significant decrease in the dark current of REs was not observed in such cases. We proposed to carry out boron diffusion in the gaps between REs and between REs and n+-GR.

Characterization and modification of biochar from a combined heat and power (CHP) plant for amending sandy soils collected from wild blueberry fields
Authors: Novak Abigayl , Li Ling , Wason Jay , Wang Jinwu , Zhang Yong-Jiang
Published: November 2023

Wild (or lowbush) blueberries (Vaccinium angustifolium Ait.) undergo severe drought impacts due to climate warming because they grow in sandy soils with poor water retention. The feasibility was studied for using biochar in a forest biomass-fueled combined heat and power (CHP) plant to amend the sandy soils. The chemico-physical properties (e.g., bulk density, moisture content, porosity, pH) of the biochar were measured. An acid treatment method (1% to 3% acidic or citric acid solution) was developed to decrease the biochar pH from 11.4 to neutral or lower, aiming to aid in weed control in wild blueberry fields. The water holding capacity (WHC) of sandy soils (S) mixed with biochar (B) (Type I) and sandy soils mixed with both biochar and fertilizer (Type II) at four ratios of 100S:0B (control), 50S:50B, 30S:70B, and 10S:90B were measured. The biochar generated from the CHP plant had comparable physical properties (such as bulk density, porosity, pH, and surface area) with woody biochar made from pyrolysis. The acid treatment method significantly lowered the pH to a range of 5.0 to 6.5. The 50:50 mixing ratio for both Type I and Type II increased the water holding capacity by about 20% compared with control groups.

Published: November 2023

The group composition of alcohol extracts from balsamic poplar leaves Populus balsamifera L, growing in the Krasnoyarsk Krai, Krasnoyarsk (Russia) were examined in this work. Leaves selected in different phases of the growing season were used: June, July, August – fresh, September – fallen leaves. Poplar leaves contain up to 56% of extractive substances, alcohol-soluble substances account for up to 67% of the extract amount. Alcohol extracts were fractionated using solvents with increasing polarity: petroleum ether (boiling point 40 to 70 °C), diethyl ether, ethyl acetate, butanol. The results showed that the alcohol extracts of poplar leaves are dominated by substances extracted with ethyl acetate (up to 60%). The study of the component composition of volatile compounds of individual fractions of alcohol extracts was performed on an Agilent chromatography-mass spectrometer. The presence of various groups of compounds was established: hydrocarbons, alcohols, acids, ketones, etc., including biologically active substances such as megasterol acetate, ℽ-sitosterol, sitosterol, 3,7,11,15-tetramethyl-2-hexadecene-1-ol, diethyltoluamide, 4-methoxy-3-nitrobiphenyl, and other compounds that it can be used in different applications.

Published: November 2023

Phosphoric acid-hydrogen peroxide (PHP) pretreatment is an effective method to obtain a cellulose-enriched fraction from biomass. In this study, artificial neural network (ANN) was used to predict PHP pretreatment efficiency of cellulose content (C-C), cellulose recovery (C-Ry), hemicellulose removal (H-Rl), and lignin removal (L-Rl) under various conditions of pretreatment time (t), temperature (T), H3PO4 concentration (Cp), and H2O2 concentration (Ch). The final optimized topology structure of the ANN models had 1 hidden layers with 9 neurons for C-C and 10 neurons for C-Ry, 10 neurons for H-Rl, and 12 neurons for L-Rl. The actual testing data fit the predicted data with R2 values ranging from 0.8070 to 0.9989. The relative importance (RI) revealed that Cp and Ch were significant factors influencing the efficiency of PHP pretreatment with total RI values ranging from 12% to 62.6%. However, their weights for the three components of biomass were different. The value of T dominated hemicellulose removal effectiveness with an RI value of 78.6%, while t did not seem to be a main factor dominating PHP pretreatment efficiency. The results of this study provide insights into the convenient development and optimization of biomass pretreatment from ANN modeling perspectives.

Convex functions and inequalities in the secondary school
Authors: Šinkūnas Juozas
Published: November 2023

A function f : Df  → R is called convex if for any x, y ∈ Df the inequality f ( x+y/2 ) \leq (f (x)+f (y)  )/2 holds. We prove the main property of the convex fonctions (inequality (4)) and also the inequalities which the arithmetic, geometric, harmonic and quadratic means of several positive numbers satisfy. Then we prove some trigonometric and geometric inequalities.
Problems for combinatorial numbers satisfying a class of triangular arrays
Authors: Belovas Igoris
Published: November 2023

Numbers satisfying a class of triangular arrays, defined by a bivariate first-order linear difference equation with linear coefficients, include a wide range of combinatorial numbers: binomial coefficients, Morgan numbers, Stirling numbers of the first and the second types, non-central Stirling numbers, Eulerian numbers, Lah numbers, and their generalizations. In this work, we derive the general analytic expression of the numbers satisfying a class of triangular arrays and propose problems (both teaching and unsolved ones) for undergraduates studying probability theory and analytical combinatorics subjects in the study programs of the fields of mathematics and computer science. Some of the unsolved challenges can also be used as the basis for a thesis.
Investigation of an attack on the multi-prime RSA cryptosystem based on cubic equations
Authors: Michalkovič Aleksėjus , Žitkevičius Jokūbas
Published: November 2023

In this paper we consider a modification of the attack on the classic RSA cryptosystem aimed at factoring the public modulus n, which is a product of three primes. To improve the performance of the modified attack we introduce additional parameters. We present the theoretical upper bound on the search range parameter and define a shifting parameter based on the empirical results. Since these changes make our attack probabilistic, we investigate the dependence of the success on the values of the newly defined parameters.

Usually, proofs of mathematical statements involve both algebraic rearrangements and logical reasoning. But there are mathematical statements whose truth is obvious at first glance when there is a diagram illustrating that proof. Although the proofs based on the drawing are not necessarily full and complete, but the drawing helps to notice facts that are then easily supported by algebra and logic. The paper presents proofs of mathematical propositions where, upon careful study of the drawing, the main idea of the proof can be seen from the drawing, and the proof itself becomes beautiful and clear.

In order to develop new approaches to the psychophysiological selection of operators, 219 male servicemen aged 20 to 40 years old with experience in operating unmanned aerial systems of the first class Light and involved in a wide range of professional tasks were examined. To study their psychophysiological status, modified methods were used using the PFI-2 hardware and software complex. The following indicators were determined: accuracy of reaction to a moving object, strength of nervous processes, functional mobility of nervous processes, simple visual-motor reaction, complex visual-motor reaction, orientation in space, and visual memory. To identify a set of informative indicators that can best divide the analyzed group of operators into 3 clusters, a stepwise discriminant analysis was applied. The technique was developed to obtain several psychophysiological profiles of vocational aptitude, equally effective in terms of content. The statistical discrepancy of these profiles has been established. Ways of evaluating the superiority of these profiles have been shown. The principle of “necessary diversity” in the implementation of occupational psychophysiological selection of operators working in conditions with increased danger has been proposed and discussed. A number of advantages of using this principle to increase accuracy and expand the contingent of persons subject to occupational psychophysiological selection have been identified. The technology of graphical presentation of psychophysiological profiles of operators of unmanned aerial complexes was developed for the purpose of assessment of suitability for professional tasks.

Common mechanisms of the development of the body’s stress response under the conditions of war and the COVID-19 pandemic relate to its acute and chronic course, post-traumatic stress disorder, the role of the hypothalamus-pituitaryadrenal gland, the sympathetic nervous system, and the renin-angiotensin-aldosterone system, and deficiency of α-1- antitrypsin. The development of stress-induced hypertensive changes is characterized by the activity of enzymes independent of the angiotensin-converting enzyme pathway of the renin-angiotensin system, expression of miRNA, damage to the endothelial cells of blood vessels, changes in the content of neutrophils and lymphocytes, and the soluble receptor for glycosylation end products. The considered stress-induced hypertensive changes under the conditions of the COVID-19 pandemic relate to chronic hyperinflammation, emotional response, effects of catecholamines, chymase activity, redox imbalance, DNA damage, endoplasmic reticulum stress. The interaction between ACE/ACE2 and miRNA may increase the probability of SARS-CoV-2 infection in patients with hypertension. A factor in the severity of COVID-19 is considered to be clinical depression and low immunity, and the possibility of a negative effect of antidepressants is highlighted. A more aggressive course of COVID-19 in hypertensive patients is associated with low levels of nitric oxide (NO). Stress-induced hypertensive changes under the conditions of war are associated with adaptation disorders, increased randomness of heart rate changes, post-traumatic stress disorder, the development of hypertension partly of psychological origin against the background of changes in the central nervous system, immunity, and the polymorphism of the ACEI/D gene as an indicator of endurance.

Анотація. Матеріалом дослідження були алюмінієві сплави АЛ9, АЛ4, АЛ4С, АЛ4Д системи Al-Si. Метою роботи є розробка технології модифікування сплаву АЛ9. Об’єктом дослідження було обрано «корпус» із литого алюмінієвого сплаву. У ході роботи досліджено будову та властивості литих алюмінієвих сплавів. Досліджено діаграму стану Al-Si, фізико-механічні властивості карбіду кремнію. Для виготовлення корпусу насоса обрано сплав АЛ9, запропоновано модифікацію сплаву з метою покращення механічних властивостей. Досліджено структуру та механічні властивості модифікованого сплаву. Комплекс проведених досліджень підтвердив модифікуючу дію карбіду кремнію в розплаві Al, відпрацьовану технологію введення в розплав SiC, оптимізовано кількість SiC. У модифікованих заготовках досягнуто подрібнення зерна та покращення властивостей сплаву. Для алюмінієвого сплаву АЛ9 вибір SiC як мікролегуючого та модифікуючого елемента обґрунтований з точки зору відповідності його фізико-хімічної природи властивостям сплавів на основі алюмінію. Вибраним модифікатором алюмінієвого сплаву АЛ9 слугував порошок карбіду кремнію з фракцією до 100 нм. Дослідженнями встановлено подрібнення зерен і структурних компонентів модифікованого сплаву в порівнянні з вихідним. За допомогою металографічного аналізу досліджено процеси під час модифікації. Встановлення технології введення в розплав карбіду кремнію та температурно-часових параметрів термообробки заготовок дозволило отримати дисперсну структуру та високий комплекс механічних властивостей литого алюмінієвого сплаву АЛ9. Запропоновано та теоретично обґрунтовано використання нанодисперсних композицій SiC та ZrC розміром до 100 нм як модифікаторів литих алюмінієвих сплавів системи Al-Si. Встановлено відповідність кристало-геометричної структури наномодифікаторів класу карбідів відносно матриці алюмінієвого сплаву. Проведений аналіз показав, що модифікатори класу карбіду SiC мають гранецентровану кубічну гратку відповідно до гранецентрованої кубічної гратки алюмінієвих сплавів. Це відповідає основним вимогам при виборі модифікаторів.
ЗАЛУЧЕННЯ ІНВЕСТИЦІЙ ДО КОСМІЧНОЇ ДІЯЛЬНОСТІ В УКРАЇНІ
Authors: Діденко М.В.
Published: November 2023

Анотація. Одним із ключових факторів успішного розвитку будь-якого сектору економіки, що в значній мірі визначає його динаміку та конкурентоздатність, є надходження інвестицій. Досвід провідних світових космічних країн (США, ЕС) свідчить, що залучення приватних інвестицій відкриває значні перспективи для розвитку галузі. Проте, однією із ключових вимог до залучення інвестицій є існування сприятливого макроекономічного середовища, наявність якого малоймовірна у поточних умовах. Ціллю статті є пошук напрямків та проектів, реалізація яких дозволить залучити приватні інвестиції до космічної діяльності в Україні. Аналіз динаміки розвитку світового ринку космічних послуг свідчить про його значне прогнозоване зростання у період до 2040 року [1]. В той же час, переважаюча кількість інвестицій на даному ринку зосереджена не в його «матеріальній частині» (пускові послуги, виготовлення космічних апаратів і т.п.), а в сфері супутників та надання послуг. І вказана диспропорція має сталу тенденцію до збільшення. В поточних ринкових умовах найбільш інвестиційно привабливими проектами, відповідно, є ті, що пов’язані із зазначеним ринковим сегментом. Так, одним із найбільш динамічно зростаючих напрямків є надання послуг, що пов’язані з машинним навчанням та інтернетом речей (M2M/IoT). Зростання цього ринкового сегменту прогнозується більшістю маркетингових досліджень. В той же час, на сьогодні науково-технічний прогрес надає можливість перенесення технології M2M/IoT на супутникову платформу габаритно меншого покоління (з мікросупутникової на наносупутникову). Реалізація проектів подібного типу має ряд переваг з точки зору привабливості для інвесторів, оскільки технічна специфіка  допускає їх виконання в два етапи. На першому етапі при відносно незначних капітальних затратах можна отримати вже  функціонуючу систему з обмеженими технічними характеристиками. Ну другому етапі, що є основним з точки зору капітальних витрат, передбачається збільшення зони покриття, пропускної здатності та інших технічних характеристик. Така модель реалізації проекту надає можливість розпочати його виконання навіть при незначних початкових інвестиціях та умовах макроекономічної нестабільності.

Published: November 2023

Esta revisão sistemática aborda a escrita psicanalítica sobre violência e preconceito. O levantamento dos artigos ocorreu nas bases de dados SciELO, Index Psi, LILACS e PsycINFO, com os descritores “violência” ou “preconceito” e “psicanálise”, publicados entre 2009 e 2019. Partiu-se de 515 publicações potencialmente relevantes e, após aplicação de critérios de inclusão e exclusão, constituiu-se o banco final de 151 artigos, integralmente lidos pelos cinco juízes independentes. Constatou-se discrepância numérica entre publicações relativas à violência (134), ao preconceito (06) e a ambas as temáticas (11). Alguns artigos abordavam a segregação e desigualdade social, porém não nomeadas como preconceito. Os resultados destacaram a relação do sujeito com a cultura, as singulares formas contemporâneas de subjetivação, o ato em detrimento da simbolização, a instauração da lei e os efeitos de seu fracasso. Para além da clínica, os aportes psicanalíticos permitem, também, denunciar e intervir em situações sociais de violência e preconceito.
