Comparison of Alumina-Titania Coatings Deposited by Plasma and HVOF Spray Techniques
Authors: Trache R. , Berger L.-M. , Leyens C.
Published: June 2023

This work demonstrates a new single-cathode, multi-anode plasma spray process and compares it with conventional APS and HVOF spraying. Alumina feedstock powders mixed with 13, 40, and 44 wt% titania were deposited under a wide range of spraying conditions following a design of experiments approach. Deposition rate and efficiency were measured and coating characteristics, including microstructure, phase composition, hardness, Young’s modulus, electrical resistivity, and cavitation wear, are compared. The results are presented and the advantages of each process are discussed.
Effect of Substrate Hardness and Gas Temperature on Deposition Behavior of Nanostructured WC-23Co Particles in Cold Spraying Process
Authors: Chen X. , Wang H. T. , Ji G. C. , Bai X. B. , Dong Z. X.
Published: June 2023

Nanostructured WC-Co powders were cold sprayed on different substrate materials at different accelerating gas temperatures. Splat morphology and microstructure were examined, showing that the splats are partially embedded in plain carbon and stainless steel substrates with a contour similar to that of the feedstock powder. Gaps and revers were observed around the splats and corrugations or ripples were found on the surface. In contrast, splats on the surface of WC-Co substrates are relatively flat with ejectas on the periphery. A comparison of splats also shows that particle deformation increases with increasing gas temperature and substrate hardness.
Cold Spray Deposition of a Core-Shell Structured WC-Co Coating
Authors: Luo X.-T. , Li C.-X. , Yang G.-J. , Li C.-J.
Published: June 2023

In this study, cold spraying is used to develop WC-Co coatings with a WC-10Co core as reinforcement and a Co-rich WC-Co matrix as the binder. Core-shell structured powders were prepared by mechanical milling and coating samples were deposited by cold spraying. Post-spray annealing was carried out to further modify the coating microstructure. WC-Co coating microstructure and mechanical properties were investigated along with various structure-property relationships. It was found that a WC-Co layer with a porosity of only 0.7 % was realized by cold spraying the mechanically milled powder and that annealing at 900 °C for 2 h resulted in a remarkable improvement in fracture toughness with no evident change in hardness.
Cold Spray Deposition on Inner Side of Pipe with Aid of Radial Supersonic Nozzle
Authors: Klinkov S. V. , Kosarev V. F. , Zaikovskii V. N.
Published: June 2023

This work evaluates a new cold-spray technique for coating the inner surface of pipes. Rather than rotate the pipe as in previous methods, a radial supersonic nozzle is translated along the pipe axis, leaving behind a continuous coating. In a demonstration, the new method is used to apply aluminum, copper, and nickel coatings inside steel and aluminum pipes with inner diameters of 45-100 mm.
Computer Modeling of Cermet Coatings Evolution Under Pulsed High-Energy Post-Treatment
Authors: Solonenko O. P. , Golovin A. A.
Published: June 2023

This study employs numerical simulations to investigate the effect of pulsed electron-beam treatments on the porosity of plasma-sprayed cermet coatings. Simulations show that heat flux density and pulse duration control both the degree of melting in the metal binder and volume heating in the base. With optimized parameters, a single high-energy pulse can reduce porosity and increase bonding strength without melting carbide inclusions.
A TEM Study of the Bonded Splat Interface Microstructure of Plasma-Sprayed YSZ Coating
Authors: Yang E.-J. , Yang G.-J. , Li C.-X. , Li C.-J.
Published: June 2023

In this work, YSZ coatings were deposited on air-cooled substrates by atmospheric plasma spraying. High-resolution transmission electron microscopy (HR-TEM) was used to examine local microstructure near the interface of bonded splats. The coatings mainly consist of typical columnar grain microstructure with metastable tetragonal phase. At the bonded zones, the top surfaces of previously deposited splats act as heterogeneous nucleation sites for the next splat. The examinations also revealed large columnar grains perpendicular to the bonded interface along with high defect density.

Authors: Zhang F. F. , Wang S. C. , Robinson B. , Tabecki A. , de Villiers-Lovelock H. L. , Wood R. J. K.
Published: June 2023

In this study, suspension HVOF spraying is used to deposit TiO2 nanoparticles on 304 stainless steel substrates. Spray parameters are varied, including spray distance and number of passes, to determine their effect on friction and wear properties as well as surface topography, microstructure, and phase composition. The spray parameters used, the microstructures observed, and the wear mechanisms of the nanostructured TiO2 coatings are described in the paper.
Al-Quds as Mentioned in UN Resolutions
Authors: ABU OUN Mohammed
Published: June 2023

Al-Quds (Jerusalem) has always enjoyed a special standing in the world for either its historic and civilised position, or for its geographically strategic location in the centre of the Arab region and the Old-World continents. Due to its importance, its issues were paid attention to on the global arena by major countries and international institutes, particularly the United Nations and its institutes. This is what prompted these institutions to express their positions on this issue, which is what we seek to address during this study. This study addresses four main claims: 1) the most prominent UN institutes influencing the Palestinian issue, 2) UN resolutions before 1967, 3) UN resolutions from 1967-1993, and 4) UN resolutions after 1993. It adopts a descriptive analysis methodology, and concludes that al-Quds is an occupied Palestinian city as described in the International Law, the international community's complicity with the occupation contributed to the Judaisation and seizure of the holy city, and the international resolutions failed to deter the occupation from violating the law. The study also recommends shedding light on the Israeli occupation, its crimes against the Palestinians, and its violations against international law in the international forums. Moreover, it recommends exerting pressure on the countries supporting the occupation through building Arab and Muslim lobbies that work on breaking the relation between those countries and the occupation, and mobilising them to support Palestinians' rights.

هدفت هذه الورقة إلى التعرف على الأداء العسكري للمقاومة الفلسطينية خلال معركة سيف القدس (مايو 2021)، وذلك من خلال دراسة بيانات فصائل المقاومة الفلسطينية، وقد ركّز الباحث على دراسة بلاغات وبيانات كتائب الشهيد عز الدين القسام الجناح العسكري لحركة المقاومة الإسلامية (حماس)، وسرايا القدس الجناح العسكري لحركة الجهاد الإسلامي؛ كونهما الفاعلان الرئيسيان في المعركة، وقد اعتمد الباحث على تحليل أثر الفعل المقاوم من خلال دراسة العديد من الأبحاث والأخبار التي نشرتها مواقع ومراكز دراسات تابعة للاحتلال. تنتمي هذه الورقة إلى البحوث الوصفية التحليلية، فقد عمد الباحث إلى استقراء الأداء العسكري للمقاومة الفلسطينية خلال المعركة؛ بتحليل البلاغات العسكرية للمقاومة الفلسطينية، في مسعى لتحديد الخطوط الأساسية التي ميّزت أداء المقاومة العسكري خلال المعركة. وقد خلُصت الورقة إلى أنّ المقاومة أخذت زمام المبادرة، ووجهت ضربة البداية، واستطاعت أن تحافظ على زخم ناري هو الأعلى في تاريخ المواجهة مع الاحتلال، وأفشلت مخططاته من خلال استخبارات فعّالة، وامتازت بقدرة عالية على القيادة والسيطرة، رغم كثافة نيران الاحتلال وإجرامه.
الدور النضالي للمرأة الفلسطينية في مدينة القدس (2000 – 2022)
Authors: KHADOORA Eman R. A.
Published: June 2023

كان للمرأة دور مركزي في النضال الفلسطيني، وبرزت إحدى تجلياته في دفاعها البطولي عن المسجد الأقصى المبارك خلال السنوات الأخيرة، جنبًا إلى جنب مع الرجل، حيث أفشلت برباطها أطماع الاحتلال والمستوطنين في إحكام السيطرة على المسجد المبارك وصولًا إلى التقسيم الزماني والمكاني. وشاركت المرأة الفلسطينية بفاعلية في النضال عبر التاريخ الفلسطيني في مدينة بيت المقدس، حيث تمكنت المرأة من الانطلاق والمساهمة في بناء المجتمع الفلسطيني، وكذلك المشاركة في الدبلوماسية الفلسطينية، والوقوف في وجه الاستيطان الصهيوني، وضد تهويد مدينة القدس والتهجير القسري للسكان، وهدم المنازل والاقتحامات المتكررة للمسجد الأقصى. فالأقصى المبارك حوله نساء قدمن كل ما يملكن من أجله، والنماذج كثيرة تشهد لها حجارة بيت المقدس وزيتونها، فتزايدت أعداد المرابطات، وأصبحن ينتهجن أساليب متعددة في دخول الأقصى، والتخفي، ومجابهة الاقتحامات، يشاركهن الرجال المرابطون في ساحاته، حتى اشتعلت انتفاضة السكاكين، وانتشر الهلع في قلوب المحتلين، حتى انخفضت أعداد المقتحمين للمسجد الأقصى إلى أقل نسبة تحققت، وذلك عام 2016.
البيئة الإستراتيجية الفلسطينية بين يدي معركة سيف القدس
Authors: ALMEGHARI Hısham
Published: June 2023

هدفت هذه الدراسة التعرف إلى طبيعة البيئة الإستراتيجية الفلسطينية بين يدي معركة "سيف القدس"، بين الاحتلال الصهيوني والمقاومة الفلسطينية في قطاع غزة، في أيار/ مايو 2021. ولتحقيق هذا الهدف استخدمت الدراسة منهجين، هما: المنهج الوصفي التحليلي، والمنهج المقارن، كما استعانت بمقاربة المصلحة الوطنية. وقد جاءت في ثلاثة محاور: عالج المحور الأول تعريف معركة سيف القدس، وأشار إلى خلفياتها وأهم أسبابها ونتائجها، فيما عالج المحور الثاني مفهوم البيئة الإستراتيجية ومركباتها وخصائصها، أما المحور الثالث فقد اهتم بدراسة وتحليل البيئة الإستراتيجية الفلسطينية في أبعادها المحلية الإقليمية والدولية. وقد خلصت الدراسة إلى إن معركة سيف القدس اندلعت لأسباب وطنية جامعة، وبمبادرة من المقاومة، وفي ظل وحدة الساحات الفلسطينية، خلافًا لما شهدته جولات العدوان الصهيوني السابقة على قطاع غزة. وفي الوقت ذاته، شاب البيئة الإستراتيجية الفلسطينية قدر كبير من المعطيات التي لم تكن لصالح القضية، على المستويات المحلية والإقليمية والدولية، بل إنها كانت أقرب إلى المصلحة الصهيونية.

Published: June 2023

Цель: Обоснование теоретико-методических положений и разработка практических рекомендаций по формированию и эффективной реализации кластерной стратегии управления реальным сектором экономики на региональном уровне. Достижение обозначенной цели потребовало решения ряда задач, в числе которых разработка предложений по формированию кластеров в реальном секторе экономики Павлодарской области, выявление и систематизация кластерных стратегий с учетом специфики отраслей, определение приоритетов стабильного взаимодействия субъектов кластера в реальном секторе региональной экономики.

Методы: Многозадачность исследования, требующая проведения аналитической оценки инновационной и инвестиционной активности промышленных предприятий региона, обусловила многоаспектность его методологии. Последнее предусматривает необходимость параллельного использования как методов системного анализа, так и традиционных методов статистического, сравнительного анализа. В качестве теоретической основы представленных в статье положений выступили труды отечественных и зарубежных и ученых, занимающихся изучением проблем формирования кластеров и основным направлениям кластерной политики в региональной экономике.

Результаты: Значимость проведенного исследования с практической точки зрения заключается в представленных конкретных рекомендациях, направленных на повышение инвестиционной привлекательности Павлодарской области и ее инновационного потенциала посредством реализации ряда кластерных инициатив в реальном секторе.

Выводы: Одной из ключевых проблем, сдерживающих развитие инновационной сферы на региональном уровне, является низкая инновационная активность предприятий на фоне того, что доминирующая часть предприятий реального сектора экономики региона обладает достаточно высоким инновационным потенциалом. Более того, с точки зрения трансфера технологий перспективы взаимодействия данных предприятий с предприятиями других секторов и отраслей экономики незначительны. Перечисленное выше во многом обусловливает актуальность исследований, направленных на определение основных методов и приоритетов формирования кластерных инициатив в региональной экономике.

Социально-экономические факторы миграции населения Карагандинской области
Authors: Хишауева Ж.Т. , Акынов Д.М. , Березюк В.И.
Published: June 2023

Цель: Определить влияние социально-экономических факторов на миграцию населения Карагандинской области.

Методы: В исследовании использованы методы абсолютных и относительных разниц, сравнительный подход, корреляционно-регрессионный анализ и программа Microsoft Excel.

Результаты: Выдвинутая гипотеза влияния среднемесячной заработной платы, среднедушевых номинальных денежных доходов населения, валовый региональный продукт (ВРП) на душу населения, стоимости жилья на миграцию населения Карагандинской области подтвердилась. Индекс реальных денежных доходов населения в рассматриваемый период повлиял на миграцию населения слабо. А гипотеза влияния уровня безработицы на миграцию населения не подтвердилась.

 Выводы: В Карагандинской области сохраняется отрицательное сальдо миграции населения. Во внешней миграции населения активно участвует городское население. Во внутренней миграции населения отмечена высокая интенсивность. За 2017–2021 гг. в Карагандинской области среднемесячная заработная плата выросла в 1,7 раза, но она ниже республиканского уровня. Среднедушевые номинальные денежные доходы населения непрерывно увеличились на протяжении всего анализируемого периода с 82299 тг до 142802 тг, а индекс реальных денежных доходов населения снизился с 108,2 до 98,2. Уровень безработицы в регионе с 2017 г. по 2020 г. снизился с 4,8 % до 4,4 %, а в 2021 г. увеличился на 0,1 пункт и составил 4,5 %. Стоимость жилья за 1 кв. м в Карагандинской области за анализируемый период растет и в 2021 г. составила 276026 тг. ВРП на душу населения в 2021 г. по сравнению с 2017 г. вырос на 2318,4, тыс. тг и составил 5419,3 тыс. тг. В регионе связь между среднемесячной заработной платой, среднедушевыми номинальными денежными доходами населения, ВРП на душу населения, стоимостью жилья и миграцией населения средняя и положительная. Связь между индексом реальных денежных доходов населения и миграцией населения слабая и положительная. Связь между уровнем безработицы и миграцией населения очень слабая и отрицательная. Социально-экономические факторы оказывают влияние на миграцию населения Карагандинской области. Отсутствие должного контроля может привести к ряду негативных последствий. Для дальнейшего развития региона необходимо устранить влияние негативных факторов. Этому должна способствовать миграционная политика. Миграционная политика, в первую очередь, должна быть направлена на сохранение и повышение численности трудоспособного населения.
Conceptual approaches to the formation and development of creative industries in an inclusive economy
Authors: Khussainova Zh.S. , Assanova M.K. , Bektleyeva D.E. , Abauova G.M , Kankulov M.K
Published: June 2023

Object: Substantiate the potential of an inclusive economy for inclusive economic growth, determine the significance and place of creative industries in them and study country modifications of the creative economy in the context of inclusive development: industrial, post-industrial and innovative dominants. Methods: As a research methodology, the dialectical method of cognition and a systematic approach are used, revealing the possibilities of scientific research of socio-economic phenomena in the development of their interrelation and interdependence.

Findings: The principles of social inclusiveness and the required components of the environment are identified. The scientific theoretical concepts of creative industries in inclusive economic growth are studied. The experience of building country modifications of the creative economy has been studied. The mechanism of inclusive economic growth as a result of the economic activity of all strata is determined, and the factors of its sustainability are determined. The advanced experience in the development of creative industries in the global space has been studied.

Conclusions: Achieving maximum involvement in economic activity of labor resources and capital leads to a slowdown in economic growth. The main indicators of economic growth have the disadvantage of unequal participation in social production and unequal access to its results. Further stable sustainable economic growth is connected with the inclusion of all social strata in the economy. Engaging inclusive human capital requires creating the necessary environment. The change in the technological structure leads to an increase in the economic significance of intangible resources as a result of intellectual labor. The key to the development of creative industries is the cognitive abilities of people with a low dependence on the capital-labor ratio. The economy of network information creates additional opportunities for the comfort of communications. The creative economy and the inclusive economy dialectically accelerate each other's development. Developing countries have developed creative clusters and become leaders in exports of creative goods. Geographically, the export of creative goods and the possession of intellectual property patents are dominated by Asian countries.

Мета дослідження – проаналізувати життєвий шлях єврея Семена Самуїловича Якерсона та мотиви прилучення до участі в Українській національно-демократичній революції 1917–1921 рр. Методологічною основою дослідження є принципи: історичної достовірності, об’єктивності, системності, науковості, всебічності та спеціальні методи: загальнонаукові – аналітичний, логічний, класифікації; історичні – історико-генетичний, ретроспективний, порівняльно-історичний; міждисциплінарні – джерелознавчий, архівознавчий, термінологічний та структурно-системний аналіз. Наукова новизна роботи полягає в комплексному дослідженні біографії Семена Якерсона як вибору служіння українському державотворенню. Висновки. Вивчення життєвого шляху єврея Семена Самуїловича Якерсона (30.11.1897–27.03.1951), сотника української армії, дало підстави стверджувати, що його шлях характерний для багатьох молодих представників єврейства, які долучилися до боротьби за будівництво суверенної  української державності. Вийшовши зі свого середовища і вступивши до військового навчального закладу та, припускаємо, мріючи про власну державу, свідомо перейшов до українського війська доби Центральної Ради. На всіх займаних військових посадах виявляв ініціативу, знання та вправно виконував спільно із ввіреними йому підрозділами військові завдання. Поразка національно-визвольних змагань не відвернула його від справ українства. Здобуваючи фах інженера-гідротехніка, закінчив Українську Господарську Академію (Подєбради), організовану українською еміграцією. Після закінчення розпочав будівничу справу на землях Закарпаття, будував мости, дороги. Друга світова війна застала його в Празі. Завдяки дружині врятувався від знищення в гетто. Після війни продовжив працю будівельника до відходу за межу земного буття.
Поведінкові стратегії уповноважених Прилуцького району доби Голодомору 1932–1933 рр. на шпальтах «Правди Прилуччини»
Authors: Якубовський Ігор
Published: June 2023

Мета дослідження полягає у з’ясуванні особливостей висвітлення на сторінках районної газети «Правда Прилуччини» поведінкових стратегій уповноважених під час Голодомору 1932–1933 рр. Методологія дослідження передбачає поєднання спеціально-історичних методів пізнання: джерелознавчого, порівняльного контекстуального аналізу, структурно-функціонального аналізу. Наукова новизна статті полягає насамперед у тому, що проблема життєвого вибору уповноважених вперше розглядається на рівні окремо взятого району. Так само вперше аналізуються інформативні можливості районної газети для з’ясування ключових тенденцій. Висновки. «Правда Прилуччини» вміщує інформацію про уповноважених за усім проблемним полем – від списків уповноважених до судових рішень із приводу покарання за пасивний чи активний спротив виконанню розпоряджень влади, спрямованих на розкручування маховика Голодомору. Баланс повідомлень про сприятливі для влади поведінкові стратегії уповноважених та прояви ігнорування її вимог свідчать про те, що значна частина уповноважених у Прилуцькому районі або відкрито не бажала брати участь у хлібозаготівлі, або намагалася непомітно загальмувати формування на селі умов, несумісних із життям. Водночас у влади бракувало реальної фактологічної бази для розміщення інформації про конкретні випадки такої діяльності, якими можна було б збалансувати критику на адресу уповноважених, що не виправдовували сподівань.  У газеті життєвий вибір осіб на користь перетворення на безвідмовних виконавців влади відобразився лише в матеріалах, зокрема й судових, розміщених у межах цинічної кампанії проти перекручень так званої «революційної законності». Усе це підштовхує до необхідності каталогізації різних форм спротиву на прикладах інших районів і врешті-решт веде до необхідності скоригувати історіографічні уявлення про реальні тенденції в середовищі уповноважених.

Published: June 2023

Konkurentno globalno tržište u 21. stoljeću podiglo je osvijestilo je bitnost poslovnih procesa kao najvažnijem konceptu upravljanja. Opsežna literatura o upravljanju poslovnim procesima sugerira kako organizacije mogu poboljšati svoju uspješnost usvajanjem procesnog pogleda na poslovanje. Međutim, nedostaju empirijska istraživanja u ovom području. Cilj ovog rada je ispitati kako procesna orijentacija (eng. Business Process Orientation, BPO) utječe na financijsku i nefinancijsku uspješnost poslovanja organizacije (eng. Organizational Performance, OP) koristeći empirijske podatke hrvatskih poduzeća. Istraživanje je provedeno metodom anketiranja, a uzorak čine 127 poslovnih organizacija Republike Hrvatske. Istraživačke hipoteze su testirane modelom strukturnih jednadžbi. Dobiveni rezultati ukazuju na to kako je BPO praksa direktno pozitivno povezana s nefinancijskom uspješnošću poslovanja, a na financijsku uspješnost ima indirektan utjecaj. Osim toga, provjeren je i utjecaj nefinancijske uspješnosti na financijsku uspješnost. Ovaj rad je vrijedan i za akademike i za poslovnu prekasu jer potvrđuje utjecaj BPO-a na OP. Poboljšano razumijevanje i jasno pokazane financijske i nefinancijske koristi od implementacije i prakticiranja BPO-a otvara širu primjenu ovakvih sustava u svakodnevnom poslovanju, što će u konačnici dovesti do njihovog usavršavanja i daljnjeg razvoja.

The author gives some forecasts of possible ways of de-velopment of the Brazilian Antarctic policy.
Transformational Leadership and Entrepreneurial Orientation: Does Gender Make Difference in The Tunisian SMEs?
Authors: Dhaouadi Karima
Published: June 2023

Abstract Given the gender gaps in leadership and entrepreneurship fields, the paper aims to examine the impact of Chief Executive Officers’ transformational leadership on firms’ entrepreneurial orientation by examining the moderating role of the gender in the context of Tunisian SMEs. A total of 630 senior managers in 210 Tunisian SMEs (3 respondents per firm) were surveyed using a questionnaire. Partial Least Squares method and Multi-Group Analysis were piloted to test the research hypotheses. The findings demonstrate that the transformational leadership drives entrepreneurial behaviours and managerial attitude towards risk in the Tunisian SMEs. The results show that male managers are more effective than female leaders in fructifying the firm’s entrepreneurial orientation when using the transformational leadership. The findings are congruent with the assumptions of the social-role theory that asserted that the female behaviour is gender stereotypic. Although Tunisian female entrepreneurs are favoured with the supportive legal status, they seem to be less entrepreneurially oriented.
Does the Expected Crude Oil Price Influence Inflation in Nigeria?
Authors: Chigozie Agu Osmond , Nyatanga Phocenah
Published: June 2023

The study examined the influence of expected oil price on inflation rate with the view of understanding the behavior of inflation as a result of shocks on the expected crude oil prices in Nigeria. The study employed an Autoregressive Distributed lag (ARDL) and Bound testing cointegration approach in order to examine both the short-run and the long-run effects of the variables. The estimation result shows that expected oil price has a significant and positive effect on inflation both in the long-run and short-run in Nigeria. Surprisingly, in the long-run, interest rate has a positive and significant effect on inflation rate as against apriori expectations. It is therefore recommended that the Nigerian government diversify its resource base, and rely less on crude oil that is more susceptible to oil price shocks, thereby reducing the effects of oil price on inflation in Nigeria. Secondly, the monetary authorities may need to use an effective interest rate policy to control the inflation rate, which in turn will stimulate investment.
Educación emprendedora con juegos serios: una estrategia para replicar

Seguramente, más de uno se sorprendió en su momento por el precio de los bombillos ahorradores. Pagar menos en la cuenta de la energía sonaba muy bien, hasta ver la gran diferencia de precio con respecto a los bombillos tradicionales. Eso fue justamente lo que detectó un joven emprendedor hace 20 años: ¿Por qué esos bombillos eran tan caros? ¿Qué sentido tenía comprarlos, si el ahorro en la cuenta de la energía prácticamente se estaba pagando por adelantado en la tirilla de compra de cada bombillo?

Sin respuestas claras, Jobst Viertel, un emprendedor colombo-alemán, decidió comprar un bombillo para investigar. Al llegar a su casa, lo desarmó y se dio cuenta de que la diferencia con un foco tradicional era bastante simple, y que la multinacional, que acaparaba las estanterías del supermercado, estaba simplemente abusando del comprador. Fue así como inició su primer emprendimiento, con el que logró fabricar bombillos ahorradores y venderlos a un tercio del precio de su competidor principal. Su filosofía era clara: hay que producir para la base de la pirámide que, en nuestro país, es la mayoría; para aquellos que ni en sueños habrían imaginado disfrutar los beneficios de los bombillos ahorradores en su casa.

Así son los emprendedores: observadores, cuestionadores; ven oportunidades y resuelven problemas; son como Clark Kent, Diana Prince o Peter Parker, gente aparentemente común, pero que esconde detrás de su ropa unas ganas incansables de transformar el mundo. Personas apasionadas y resilientes, que muchas veces salvan patria cuando se habla de desigualdad, desempleo, entre otros. Por eso, no es de sorprenderse que, en una época donde la creciente incertidumbre juega con la economía mundial a su antojo, el emprendimiento se esté convirtiendo en uno de los activos más importantes de todos los países.

Authors: Gauch Mirjam , Corsten Sabine , Geschke Katharina , Heinrich Isabel , Spelter Bianca
Published: June 2023

BACKGROUND: The use of telediagnostics for people with primary progressive aphasia (PPA) could improve access to specialised care. There is a gap in research, especially regarding to the evaluation of communicative-pragmatic measurement tools in a digital setting. OBJECTIVE: This study examined the equivalence, modality use, and patient satisfaction of telepractice administration of the Scenario Test (ST) in people with PPA. METHODS: In a cross-over design, the ST was conducted once by videoconferencing and once in person. Fifteen people with PPA participated. Participant satisfaction was assessed after each test session using a short self-designed questionnaire. The total ST scores, the use of the different communicative modalities and the participant satisfaction scores were evaluated using the equivalence and McNemar test. RESULTS: Statistical equivalence was established for the present sample with regard to the total score of the ST. Regarding the use of the different modalities, no significant difference was found. Sample satisfaction was positive for both diagnostic settings, but there was no statistical equivalence of satisfaction. Severe psychiatric and cognitive symptoms affected the test performance. CONCLUSIONS: This study highlights opportunities and limitations of telepractice administration of the ST in people with PPA. There is some evidence that testing with the ST via videoconferencing is feasible. Differences in the use of communication modalities and participant satisfaction should be further investigated. Influencing factors such as psychiatric symptoms and cognitive deficits should be considered in future research projects.
On the hyperbolic relaxation of the Cahn–Hilliard equation with a mass source
Authors: Dor Dieunel
Published: June 2023

In this paper, we consider the hyperbolic Cahn–Hilliard equation with a proliferation term, which has applications in biology. First, we study the well-posedness and the regularity of the solutions, which then allow us to study the dissipativity and the high-order dissipativity and finally the existence of the exponential attractor with Dirichlet boundary conditions. Finally, we give numerical simulations that confirm the results.

Published: June 2023

Background:

Centella asiatica (L.) ( C. asiatica) is commonly known in South East and South East Asia communities for its nutritional and medicinal benefits. Besides being traditionally used to enhance memory and accelerate wound healing, its phytochemicals have been extensively documented for their neuroprotective, neuroregenerative, and antioxidant properties.

Objective:

The present study aims to investigate the effects of a standardized raw extract of C. asiatica (RECA) on hydrogen peroxide (H2O2)-induced oxidative stress and apoptotic death in neural-like cells derived from mouse embryonic stem (ES) cell line.

Methods:

A transgenic mouse ES cell (46C) was differentiated into neural-like cells using 4-/4+ protocol with addition of all-trans retinoic acid. These cells were then exposed to H2O2 for 24 h. The effects of RECA on H2O2-induced neural-like cells were assessed through cell viability, apoptosis, and reactive oxygen species (ROS) assays, as well as neurite length measurement. The gene expression levels of neuronal-specific and antioxidant markers were assessed by RT-qPCR analysis.

Results:

Pre-treatment with H2O2 for 24 hours, in a dose-dependent manner, damaged neural-like cells as marked by a decrease in cell viability, substantial increase in intracellular ROS accumulation, and increase in apoptotic rate compared to untreated cells. These cells were used to treat with RECA. Treatment with RECA for 48 h remarkably restored cell survival and promoted neurite outgrowth in the H2O2- damaged neurons by increasing cell viability and decreasing ROS activity. RT-qPCR analysis revealed that RECA upregulated the level of antioxidant genes such as thioredoxin-1 ( Trx-1) and heme oxygenase-1 ( HO-1) of treated cells, as well as the expression level of neuronal-specific markers such as Tuj1 and MAP2 genes, suggesting their contribution in neuritogenic effect.

Conclusion:

Our findings indicate that RECA promotes neuroregenerative effects and exhibits antioxidant properties, suggesting a valuable synergistic activity of its phytochemical constituents, thus, making the extract a promising candidate in preventing or treating oxidative stress-associated Alzheimer’s disease.

Published: June 2023

Background: In Japan, only oral formulation of donepezil hydrochloride is approved for the treatment of Alzheimer’s disease. Objective: To evaluate safety and efficacy of a donepezil patch 27.5 mg application for 52 weeks in patients with mild-to-moderate Alzheimer’s disease; and to evaluate safety on switching from donepezil hydrochloride tablets. Methods: This 28-week, open-label study (jRCT2080224517) is an extension of a 24-week double-blind (donepezil patch 27.5 mg versus donepezil hydrochloride tablet 5 mg) noninferiority study. The patch group (continuation group) continued administration of the patch and the tablet group (switch group) switched to the patch in this study. Results: A total of 301 patients participated (156 patients continued using patches; 145 patients switched). Both groups showed similar course on the Alzheimer’s Disease Assessment Scale-cognitive component-Japanese version (ADAS-Jcog) and ABC dementia scales. At weeks 36 and 52, changes in ADAS-Jcog from week 24 [mean (standard deviation)] were 1.4 (4.8) and 2.1 (4.9) in the continuation group, and 1.0 (4.2), and 1.6 (5.4) in the switch group. The incidence of adverse events at application site in the continuation group over 52 weeks was 56.6% (98/173). Erythema, pruritus, and contact dermatitis at application site were observed in more than 10 patients each. There was no additional adverse event of clinical concern, and no increase in their incidence from the double-blind study. During the four weeks following switching, no patient discontinued or suspended administration due to adverse events. Conclusion: Application of the patch for 52 weeks was well tolerated and feasible, including switching from tablets.

Published: June 2023

For compensating the gap of present investigations, which did not consider the effect of skin depth before, a novel method is also proposed to obtain the eddy current force. At the beginning, the separating principle of eddy current separator (ECS) is given. Then, based on boundary conditions and the eddy current equations, the internal magnetic flux density, eddy current density and eddy current force density of non-ferrous metal are deduced. By calculating the double integral of eddy current density, the internal eddy current of non-ferrous metal is achieved. The theoretical calculation method (TCM) for solving the eddy current force in the process of non-ferrous metal sorting is proposed. Moreover, to verify the correctness of TCM, taking 24-pole and 30-pole magnetic roller as examples, the finite element models of static and transient magnetic field are established respectively. Additionally, the correctness of TCM is proven by finite element method (FEM) when the x-axis and y-axis component of eddy current force is calculated. At the end, by the theoretical analysis and derivation derived in this paper, based on the relationship between the relative position of N and S poles of the magnetic roller and non-ferrous metal, the internal eddy current force are analyzed by the consistency between the direction of the internal magnetic flux density and the eddy current of non-ferrous metal. The influence of the size relationship between the non-ferrous metal and a single magnetic pole on the separation effect is discussed.
Random periodic oscillations and global mean-square exponential stability of discrete-space and discrete-time stochastic competitive neural networks with Dirichlet boundary condition
Authors: Yuan Ting , Qu Huizhen , Pan Dong
Published: June 2023

The current article explores the affects of space-time discrete stochastic competitive neural networks. In line with a discrete-space and discrete-time constant variation formula, boundedness and stability are addressed to the space-time discrete stochastic competitive neural networks. Notably, the best convergence speed can be computed by a non-linear optimization problem. In the end, random periodic sequences with respect to time variable of the discrete-space and discrete-time stochastic competitive neural networks are discussed. The results indicate that spatial diffusion with non-negative density factors has no effect on the global mean square boundedness and stability and random periodicity of the network model. The current article is precursory in consideration of space-time discrete competitive neural networks.
Reduction in a fuzzy probability information system based on incomplete set-valued data
Authors: Li Zhaowen , Luo Damei , Yu Guangji
Published: June 2023

Attribute reduction for incomplete data is a hot topic in rough set theory (RST). A fuzzy probabilistic information system (FPIS) combines of fuzzy relations that satisfy the probability distribution about objects, which can be regarded as an information system (IS) with fuzzy relations. This paper studies attribute reduction in an FPIS. Based on the available information of objects on an ISVIS, the probability distribution formula of objects is first defined. Then, an FPIS can be induced by an ISVIS. Next, attribute reduction in a FPIS is proposed similar to an IS. Moreover, information granulation and information entropy in an FPIS is defined, and the corresponding algorithms are constructed. Finally, the effectiveness of the constructed algorithms is verified by k-means clustering, Friedman test and Nemenyi test.
