Authors: Bojor Laviniu
Published: July 2024

This study examines the effectiveness of digital game-based scenarios and wargaming in developing tactical skills and decision-making abilities among military cadets. Utilizing the ARMA 3 game, three tactical scenarios—offensive, defensive, and stability and support operations—were tested. The study involved cadets from “Nicolae Bălcescu” Land Forces Academy (NBLFA) Sibiu, selected for their interest in gaming, familiarity with ARMA 3, and knowledge of military tactics. The results showed multiple advantages of using game-based scenarios in military training. The immersive environment provided by ARMA 3 enabled cadets to simulate realistic combat situations, enhancing their involvement and enthusiasm, leading to better knowledge absorption and skills development. Wargaming offered a safe learning environment, eliminating the risks of real exercises while allowing cadets to experience specific events and incidents. In the offensive mission, cadets faced challenges due to incomplete map analysis, highlighting the need to complement map analysis with real terrain reconnaissance. The defensive scenario underscored the importance of flexibility and adaptability of the combat forces’ disposition. In the stability and support scenario, cadets effectively managed civilian-military interactions, demonstrating the potential of digital games to develop broader competencies in multicultural communication and negotiation. The study concludes that digital game-based scenarios effectively prepare leaders for contemporary conflicts marked by conventional or hybrid threats. It recommends implementing a specific wargaming discipline in the military higher education curriculum and extending this approach to Land Forces units for continuous professional development.

Published: July 2024

The digital transformation of healthcare, education, industry, and agriculture has generated new opportunities but also led to an increased use of digital devices that will lead to an increase in electronic waste (e-waste) at the end of the life cycle of these devices. In this paper, we report the electromagnetic properties of plant leaves from ten of the most used flowers that can be used to produce environmentally friendly microstrip antennas or fully biodegradable sensors for application in smart agriculture. The analysis of the results for the electromagnetic properties of the leaves of selected plants showed that the real part of the relative permittivity varied widely from 22.962 to 67.43387 for the leaves of garden plants and from 27.82699 to 55.80639 for the potted plants. The variation of the loss tangent of leaves is quite similar in potted (from 0.22718 to 0.35972) and garden (from 0.22812 to 0.33277) flowers.

Published: July 2024

Pyrotechnic compositions are mixtures of several components which, when ignited, undergo energetic chemical reactions at a controlled rate to produce on-demand delay times, amounts of heat, noise, smoke, light or IR radiation. In general, pyrotechnic compositions are easily ignited, burn quickly and produce residues that are very hot. 2-Chlorbenzalmalononitrile (CS) belongs to the category of riot control agents and is used in various pyrotechnic tear gas compositions.

The thermal characterization of tear pyrotechnic compositions is important for setting operating limits in the safety of the production process, storage, handling and even safe demilitarization.

In this sense, an experimental study was carried out to evaluate the behavior of CS at high temperatures, at different heating rates, by differential scanning calorimetry. Thermal changes were evaluated at a heating rate of 10, 20, 100 and 200οC/minute. The remaining residue was extracted in a suitable organic solvent and analyzed by gas chromatography coupled with mass spectrometry for the detection, identification and confirmation of the products formed during the controlled heating processes.

Authors: Szabolcsi Róbert
Published: July 2024

The unintentional inputs of the UAV operators in certain conditions might lead to the unwanted, pilot induced oscillations (PiO) of the aircraft. The PiOs might cause severe damages of the UAV, or as the worth, might lead to the loss of the aircraft. The PiOs of the manned aircraft are in the focus of attention for many decades. However, the PiOs of the UAVs became an important issue worth to investigate only in the past few years. Thus, scientific results and proven statements gained in this field might enrich both the on-going UAV operator training programs and UAV autopilot design based mostly on traditional synthesis methods and procedures.
Interactions of Spot Foreign Exchange Markets among Taiwan, Hong Kong and Japan: Japanese Forward Premium/Discount as an Information Variable
Authors: LIU Hsiang-Hsi
Published: July 2024

This study takes the foreign exchange rates of Taiwan, Hong Kong and Japan as the research issue, and utilises the VEC GJR-Asymmetric GARCH model to analyse the interaction among spot exchange rates of these three countries. The empirical results prove that the average returns of all foreign exchange markets have their own- and cross-spillovers, and the volatility of the return rate exists ARCH and /or GARCH effects. In addition, using Japanese forward premium/discount as information variable, empirical results find that Japanese forward premium/discount have important explanatory power for the links of Taiwan, Hong Kong, and Japanese spot exchange rates, and the original volatility spillover effect has disappeared, indicating that Japanese forward premium/discount is indeed an information variable. In terms of the volatility asymmetry effect, the results show that the estimated coefficients of asymmetry in Taiwan and Japan are positively significant, indicating that under the impact of bad news, their own market volatilities will be greater than good news. We also justify that the foreign exchange rates of Taiwan and Hong Kong, Taiwan and Japan, and Hong Kong and Japan are more closely linked to each other in the face of the two major events. The US-China trade war and the COVID-19 outbreak have triggered risk contagion, with a crisis in one country quickly spreading to another, intensifying the link between the foreign exchange markets of Taiwan, Hong Kong, and Japan. Our findings may help investors and policymakers find responses to such foreign exchange market turbulence.

Published: July 2024

In this paper, we extend the capability of a newly developed numerical scheme based on our preceding linear conformal and non-conformal finite element methods (FEM) to study 2D shallow water equations (SWE) with various boundaries. Unlike usual approach, we approximate the unknown in a staggered grid due to the use of linear alternating basis. Here, the free surface is approximated using a conformal while the velocity potential is approximated using a non-conformal linear basis. As a result, the varational problem must be reformulated. The resulting scheme is a ODE system which is easy to solve by any time integration method. Therefore, our method is staggered in space, explicit, flexible and simple to implement. The simulation results show that the flexibility of the scheme can be interpreted as the successful use of various boundary conditions.

Published: July 2024

В работе представлены результаты исследований содержания валовых и подвижных форм кадмия в дерново-подзолистых почвах, удобряемых высокими нормами жидкой фракции навозных стоков, и в почве контрольных участков. Содержание валового Cd в почве контрольных участков составляло 0.01–0.04 мг/кг, а в обрабатываемых почвах 0.09–0.10 мг/кг, что свидетельствует о его накоплении в корнеобитаемом слое. Для сельскохозяйственных почв характерно и более высокое содержание подвижного Cd. В лабораторном эксперименте изучено влияние известняковой муки и фосфоритов Верхнекамских бедных на подвижность Cd в разных по кислотности и содержанию органического вещества почвах. Установлено, что оба мелиоранта не оказывают существенного влияния на накопление подвижных форм кадмия, однако в образцах почвы с добавкой известняковой муки отмечалась тенденция к переходу Сd в подвижную форму. Через 8 недель после внесения добавок содержание подвижного Cd в образцах почвы с добавкой фосфоритов была ниже, чем в почве с добавкой известняковой муки. Полученные результаты показывают, что выбор мелиорантов для реабилитации загрязненных Cd почв имеет принципиальное значение.

Материалы мультиспектрального дистанционного зондирования Земли космическими аппаратами стали основным регулярно обновляемым источником оперативной информации в таких областях как лесное и сельское хозяйство, почвоведение, исследования криосферы, мониторинг последствий глобального потепления и пр. В статье проведен обзор российских космических спутников, осуществляющих мониторинг земной поверхности в режиме мультиспектральной съемки, сравнение параметров спутниковых снимков с иностранными источниками данных дистанционного зондирования Земли и оценка основных характеристик спутниковых снимков, определяющих возможность их применения для создания систем агро- и экологического мониторинга. Рассмотрены параметры аппаратов Landsat 8 и 9, Sentinel-2, Аист-2Д, Канопус-В, Ресурс-П, Метеор-М. Во всех спутниках пространственное разрешение зависит от режима съемки и типа сенсора. Все российские аппараты обладают довольно высоким разрешением в мультиспектральном режиме. Из архивных данных наилучшее разрешение у спутника Ресурс-П – 3 м. Наличие красного и ближнего инфракрасного диапазона во всех спутниковых системах позволяет производить расчет наиболее распространенных спектральных индексов для характеристики общего состояния растительного покрова, таких как NDVI, RVI, SAVI, TVI. Наличие дополнительных слоев в диапазоне красного барьера фотосинтеза (RedEdge слои) и коротковолновом инфракрасном диапазоне предоставляет дополнительные возможности анализа параметров зеленой биомассы растений. На примере территории Республики Татарстан (РТ) рассмотрено временное разрешение и пространственное покрытие материалами съемки. Для любой точки территории РТ доступно 10-26 снимков Landsat с общей облачностью менее 30% за вегетационный период. Спутники Sentinel-2 обеспечивают порядка 10-45 снимков с общей облачностью менее 30% за вегетационный период. Пространственное и временное покрытие российских аппаратов имеет существенные ограничения. Наилучшее покрытие поверхности земли среди отечественных спутниковых систем обеспечивает группа аппаратов Канопус-В. При этом распределение снимков крайне неравномерно. На территории РТ есть как области с высокой плотностью снимков за вегетационный период (порядка 15-20 шт), так и области, не охваченные снимками вовсе.
ОСОБЕННОСТИ РАЗВИТИЯ МИКРОБНЫХ СООБЩЕСТВ В НИЖНЕМ ТЕЧЕНИИ Р. КАЗАНКИ (Г. КАЗАНЬ) ПОД ВЛИЯНИЕМ ГИДРОХИМИЧЕСКИХ УСЛОВИЙ
Authors: Морозова Ольга Владимировна
Published: July 2024

Изменения численности микробных сообществ в нижнем течении р. Казанки в зависимости от гидрохимических факторов среды исследовались летом 2022 г. Установлено, что качество воды по микробиологическим показателям оценивается как «слабозагрязненная» (II класс). Экологическое состояние донных отложений на основе показателей бактериобентоса оценивается как «норма» ‒ «состояние риска». Наибольшее влияние на развитие бактериопланктона оказывают концентрации азотных соединений, что указывает на вовлеченность водных микроорганизмов в круговорот азота в речной экосистеме. Изменения жесткости воды, концентрации гидрокарбонатов, кальция и магния также отражаются на структуре микробных сообществ.
ЕФЕКТ МЕДУЗИ: ПРОКЛЯТТЯ ДЗЕРКАЛ І МЕЧІВ У ШЕДЕВРАХ СВІТОВОЇ ЛІТЕРАТУРИ
Authors: СКОРОФАТОВА Анна
Published: July 2024

У статті проаналізовано міф про Медузу Горгону як психодинамічну модель, що є теоретичним уявленням про те, що людську поведінку формують неусвідомлювані динамічні (інтерактивні) психологічні сили (статевий потяг, минулий травматичний досвід, нав’язані родинні цінності тощо), та викладено результати застосування техніки текстового аналізу «ефект Медузи» з опорними позиціями – дзеркало (відображення неусвідомлюваного) і меч (агресія) (авторська методика на засадах системного підходу з використанням міфологічного методу, елементів юнгіанської теорії архетипів, психологічного, герменевтичного, постструктуралістського та інтертекстуального методів), здісненого на матеріалі новели Рюноске Акутаґави «У чагарнику», психологічного роману Германа Гессе «Степовий вовк» та драми Лесі Українки «Камінний господар». Досліджено динаміку агресивної поведінки головних героїв, тригери, що провокують активацію архетипу, запропоновані у творах варіанти виходу за межі психодинамічної моделі Медузи. Встановлено, що в новелі «У чагарнику» Рюноске Акутаґави та романі «Степовий вовк» Германа Гессе виділено чотири типи персонажів, дії яких описано за допомогою психодинамічної моделі Медузи, за принципом «виходу» – Тадзьомару («відтинання голови», фізичне знищення), самурай (самознищення), жінка (ізоляція), Гарі Галер (інтелектуалізація). Відповідно в драмі Лесі Українки «Камінний господар» спостережено, за тим самим принципом, протиставлення трьох персонажів, дії яких описано психодинамічною моделлю Медузи: Командора (Медуза каральна), Долорес (Медуза витіснена, інтелектуалізована) та Дон Жуана (Медуза самозаклята), – Анні як Горгоні звичайній, спраглій влади та підкорення чужої волі. Актуальність дослідження та перспектива подальших розробок вмотивовані тим, що результати глибинного аналізу знакових літературних творів можуть бути використані в прикладній психології, зокрема в роботі з розладами поведінки, зокрема в ситуаціях повторюваних життєвих сценаріїв (індивідуальних міфів).
КОНЦЕПТ ТЕРПІННЯ В АНГЛОМОВНІЙ КАРТИНІ СВІТУ

У статті розглянуто визначення та характеристику концепту в рамках основних аспектів його дослідження. Вивчення концепту як когнітивної одиниці почалося давно і триває донині. Існує сім основних аспектів вивчення концепту: логіко-філософський, власне філософський, лінгвістичний, лінгвокультурологічний, когнітивний, психолінгвістичний та літературно-культурологічний. Філософська традиція трактує концепт як скорочене знання про світ. З погляду гносеології концепт кваліфікують як складні мисленнєві утворення, думки, виражені словами, знання, віра, розум. Як частина рефлексивної теорії концепти – це значення, які люди використовують у процесі інтерналізації знань про навколишнє середовище. У лінгвістичній літературі концепт розглядають як універсальну сутність, формовану у свідомості на основі безпосереднього чуттєвого досвіду, безпосередніх операцій людини з предметами. Представники лінгвокультурологічного підходу трактують концепт як багатовимірне семантичне утворення, у якому виділяють ціннісний, образний і концептуальний аспекти. Основними ознаками концепту є передача і збереження знань, неізольованість, цілісність, креативність, абстрактність, ментальність, емоційність та інші. Концепти вербалізуються окремими словами, ідіоматичними одиницями та реченнями, які проходять лексикалізацію та ідіоматизацію, і відтворюються в мовленні автоматично за наявності певних асоціацій у комунікативній ситуації. Провівши семантико-етимологічний аналіз слова patience, ми дійшли висновку, що семантична структура концепту PATIENCE в англійській мові складається з різних значень, які утворюють єдине ціле. Концепт PATIENCE широко представлений в англійській лінгвокультурі, а його основними, тобто ядерними, ознаками є: 1) очікування; 2) витривалість; 3) слухняність; 4) страждання; 5) самоконтроль; 6) експозиція; 7) поблажливість; 8) наполегливість.
A experiência como possibilidade para a ecologia da ação na perspectiva de(s)colonizadora
Authors: Dju Antonio Oliveira , Muraro Darcisio Natal
Published: July 2024

O artigo analisa a concepção de experiência como modo de vida e sua relevância para a “ecologia de saberes”, contrapondo paradigmas hegemônicos e coloniais. Destaca o pragmatismo epistêmico de John Dewey, defendendo sua contribuição para a inteligibilidade da experiência dos oprimidos. Questiona se Dewey promove a de(s)colonização do saber. Ao utilizar uma abordagem qualitativa na Filosofia de Educação e dialogar com Grazziontin, Klaus e Pereira (2022), conclui que a teoria de Dewey incentiva a ação descolonizadora, emergindo da reflexão crítica e prática transformadora. Assim, sua concepção de experiência é fundamental para uma ecologia de saberes e fazeres, de modo que fortalece a de(s)colonialidade como modo de vida.

El glioblastoma multiforme es un tumor cerebral letal. Los esfuerzos experimentales realizados hasta hoy han mejorado nuestra comprensión sobre la fisiopatología de dicho tumor. Sin embargo, es necesario encontrar objetivos moleculares para identificar vulnerabilidades potenciales y abordar su patogénesis eficientemente. Este trabajo estudió tumores cerebrales de glioblastoma multiforme extirpados de dos pacientes. A través de registros de Ca2+ intracelular in situ e in vitro, RT-PCR de punto final y experimentos histológicos se caracterizó parcialmente el origen de las respuestas de Ca2+ intracelular en células de glioblastoma multiforme humano expuestos a diversas concentraciones extracelulares iónicas y de transmisores químicos. Con ello se encontró que el 70% de las células de glioblastoma multiforme generaron movimientos espontáneos de Ca2+ intracelular, entre los cuales aproximadamente el 9% mostró fluctuaciones rítmicas, incluso en ausencia de calcio y sodio extracelular. Además, los antagonistas de IP3R y SERCA no inhibieron completamente las respuestas de Ca2+ intracelular, mientras que los estudios de RT-PCR mostraron la expresión de S100A9, KCNH1, SLC12A5 y SLC8A1. Estos resultados sugieren la participación de estas proteínas como parte de la maquinaria de señalización celular del glioblastoma multiforme.
