Objectives: The main objective of the research was to build a ceramic filter bed, using red clay and diatomite, for the removal of arsenic in aqueous media and to propose an environmentally friendly and low-cost technique for rural communities in Peru that consume water contaminated with arsenic.
 
Theoretical framework: Arsenic is a common contaminant in the drinking water of many rural communities in Peru, exceeding the limits allowed by the WHO. Prolonged exposure to arsenic can cause serious health problems. The use of low-cost non-metallic materials, such as thermally activated clay and diatomite, is proposed for its adsorption.
 
Method: A filter bed composed of 5 cm layers of red clay and diatomite with particle sizes of 0.81, 0.31 and 0.20 mm was used. Both materials were thermally activated at 900°C and placed on a stainless steel support. The arsenic removal process was evaluated by passing a synthetic solution with 13.99 ppm of arsenic through the bed. Material characterization analyses were performed before and after the adsorption process, using techniques such as ICP-OES, SEM, FTIR, among others.
 
Results and discussion: The filter bed composed of diatomite (83.31% SiO2) and red clay (8.23% Fe2O3) achieved an arsenic removal of up to 99.99%, highlighting the efficiency of particles with a size of 0.20 mm. This shows that the combination of these materials can be highly effective in removing arsenic in water, which is promising for its implementation in rural areas.
 
Research implications: This research has important implications for water treatment in rural communities facing arsenic contamination problems. The technique developed is low-cost and uses abundant resources, which facilitates its application at the local level and promotes sustainable solutions for access to safe drinking water.
Originality/Value: The research provides a novel approach through the use of red clay and diatomite, accessible resources, thermally activated for the removal of arsenic in water. In addition, the high removal effectiveness achieved provides a potentially scalable and replicable solution in other rural communities with similar problems.
Krankenhaussterblichkeit bei Patienten mit und ohne Demenz

In times of demographic change, the number of patients affected by Alzheimer's disease and other related dementias will increase dramatically [1]. This increasing prevalence will also have an impact on hospitals. They will be confronted with an increased workload due to rising admissions of dementia patients and their need for complex treatment and care measures [2]. A recent study by Sampson et al [3] examined the prevalence of dementia in older people over the age of 70 admitted to hospital as emergency cases. The study found that more than 42% of admitted patients suffered from dementia. These results are consistent with a cross-sectional study of patients aged 65 years and older in randomly selected general hospitals in Germany [4]. It confirmed that 40% of patients over the age of 65 suffered from mild cognitive impairment or dementia. These patients were more frequently treated for dehydration, electrolyte disturbances, urinary tract infections, bruises and fractures, as well as symptoms and findings of unknown nature [5]. Patients with severe impairments, such as dementia, require special care. A key aspect that requires attention is the hospital mortality of this population group. An observational cohort study from 2010 linked data from three national registers in the Netherlands, which included 40,500 patients aged 60 to 100 years. It showed that in addition to male gender (adjusted hazard ratio (HR) 1.52, 95% confidence interval (95% CI) 1.43-1.63) and older age (adjusted HR 1.03, 95% CI 1.03-1.04), the presence of Alzheimer's disease (adjusted HR 1.21, 95% CI 1.13-1.29) also increased the risk of hospital mortality [6]. Later studies confirmed this increased likelihood of hospital mortality in patients with Alzheimer's disease or other related dementias with comparable results (odds and hazard ratios between 1.1 and 1.2) [7, 8]. Dementia is therefore a predictor of hospital mortality in hospitalised persons.
Problems and prospects of scientific and technological cooperation between Russia and India in modern conditions: international legal dimension
Authors: Shugurov Mark Vladimirovich , Pechatnova Yuliya Vadimovna
Published: October 2024

The subject of the study is the intensification of cooperation between Russia and India in the field of science, technology and innovation in the context of responding to anti-Russian sanctions against Russian science. The purpose of the article is to identify the initiative directions of scientific and technological cooperation between the two countries in modern conditions, which will effectively implement the provisions that form a systemic legal framework for bilateral cooperation. The article shows that Russia is the initiator of the intensification of cooperation, intending to compensate for the damage caused by the loss of institutional ties with some of the main partner states in the scientific field. The authors elaborate on the characteristics of the mechanism of legal regulation of Russian-Indian scientific and technological cooperation both from the point of view of its historical formation and through the prism of its compliance with the modern needs of intensifying bilateral cooperation. In the process of achieving the research goal and solving the tasks set, the authors used the following methods and approaches: historical and legal method, forecasting method, formal dogmatic method, systematic approach, modeling method. The authors of the article came to the conclusion that the operation of the developed international legal mechanism for regulating the ISTC of the two countries has become the basis for the successes achieved in long-term cooperation. This mechanism combines the implementation of the provisions of intergovernmental bilateral agreements (vertical level), as well as the provisions of agreements concluded between Russian and Indian institutions of the scientific and educational sphere (horizontal level). The directions of cooperation and the prospects for its regulation are set by political and legal documents of a strategic nature (declarations, statements, memoranda). All this is complemented by the use of a programmatic method that creates conditions for the implementation of relevant international legal obligations. The organizational mechanism is represented by intergovernmental structures. At the same time, currently this cooperation is not so significant in its scope, and the provisions of political and legal documents sometimes have the character of declarative intentions, which are not yet embodied in a wide range of specific scientific projects. The novelty of the article lies in understanding the prospects of the Russian-Indian ISTC through the prism of solving the problem of enhancing Russia's participation in cooperation in geographical areas not complicated by sanctions.
Enhancing Acromioclavicular Rehabilitation and Functional Capacity With Blood Flow Restriction Training: A Case Report
Authors: Montemayor John Connor , Jeanfavre Michael , Leff Gretchen
Published: October 2024

BACKGROUND: Type V Acromioclavicular joint (ACJ) separations often require surgical stabilization to restore functional capacity of the shoulder. However, the purpose of this case study is to demonstrate nonsurgical management of this condition.

CASE PRESENTATION: A 32-year-old female with a radiographic type V ACJ separation underwent nonsurgical management. This case used a novel criteria-based protocol, which utilized 6 weeks of upper extremity blood flow restriction to restore the functional capacity of a radiographic type V ACJ separation.

OUTCOME AND FOLLOW-UP: Following nonsurgical management, there was a 2.47-fold increase in external rotation strength, 97% limb symmetry on upper quarter Y-Balance, a score of 91 on American Shoulder and Elbow Surgeons assessment, and a 9-mm radiographic reduction of the coracoclavicular interval.

DISCUSSION: The case illustrates how clinical findings did match the radiographical findings, but the nonsurgical treatment using upper extremity blood flow restriction provided a desired functional outcome. JOSPT Cases 2024;4(4):185-199. Epub 29 October 2024. doi:10.2519/josptcases.2024.0031
The Impact of Exaggerated and Deceptive Influencer Advertising and Influencer Attractiveness on Consumer Purchase Intentions
Authors: Ayar İlknur
Published: October 2024

Influencer marketing is a growing trend where companies hire social media influencers to promote their brands through paid content. Influencers create engaging posts and interact with their followers to share personal experiences. However, consumers have expressed concerns about the potential negative effects of these promotions. Focusing on the negative aspects of influencer marketing, this study illustrates how followers perceive the misleading techniques used by influencers. This research aims to see how influencer appeal affects consumers' purchase intentions in exaggerated advertising generated by influencers. The data was gathered through an online survey. Three hundred eighty-eight valid responses were received from active Instagram users. SPSS and AMOS programs were utilized to assess the data and examine hypotheses. This study finds that deceptive adverts made by influencers negatively affect their attractiveness and significantly reduce purchase intentions. In contrast, exaggerated advertisements do not affect purchase intention. As expected, influencers' attractiveness is positively related to purchase intention. These findings emphasise the importance of ethical advertising practices in influencer campaigns.
Роман Ильич Грубер и семья Гессенов: к истории потерянных связей
Authors: Н.А. Яковлева
Published: October 2024

Статья посвящена неисследованному сюжету в биографии известного музыковеда Р. И. Грубера, состоявшего в близком родстве с петербургской семьей общественного деятеля, издателя, публициста И. В. Гессена. Круг творческой интеллигенции, частью которого были Гессены, сыграл до революции значительную роль в жизни будущего ученого. В статье представлены новые материалы, свидетельствую щие о тесных контактах Романа Грубера с родственниками, эмигрировавшими в пер вые годы советской власти. Именно в петербургском салоне Гессенов, оставившем свой след в истории, состоялось неформальное знакомство Грубера с деятелями му зыкальной культуры и, в частности, с авторитетным музыкальным критиком и ком позитором В. Г. Каратыгиным, вскоре ставшим его педагогом и, как известно, впоследствии оказавшим влияние на его профессиональное становление. К этому периоду относится и дебют ученого, выступившего с критическими заметками о текущих музыкальных событиях в газете «Речь», издававшейся И. В. Гессеном. Неопубликованные материалы, представленные в работе, проливают свет на некоторые обстоятельства его детства, переезда в Петербург, а также дают возможность «увидеть» его в близком семейном окружении в атмосфере первых лет революции. Помимо свидетельств личного происхождения, в работе привлекаются другие архивные источники, позволяющие восстановить и подтвердить утраченные и забытые факты.

The article is devoted to an unknown circumstance in the biography of the fa mous musicologist Roman I. Gruber, who was closely related to the St. Petersburg family of the public figure, publisher, and publicist Iosif V. Hessen. This family was a part of the cur tain circle of intellectuals, played a significant role in the life of the future scientist before the revolution and in many respects influenced his choice of profession. The article presents new evidence of Roman Gruber’s close contacts with relatives who emigrated in the early years of Soviet power. It was the Hessens’ salon, where Gruber’s has met the leading figures of mu sical culture, and, for instance, the prominent music critic and composer Vyacheslav G. Kara tygin, who became his teacher and deeply influenced his professional development. During this period Gruber also started to publish the articles upon current musical event in Hessen’s newspaper Rech (“Speech”). Unpublished materials presented in the work shed light on some of the circumstances of Gruber’s childhood, his arrival to St. Petersburg, and give an op portunity to observe him in his close family environment of the early years of the revolution. In addition, archival sources are also used to fill in the gaps in his mother’s biography and in the genealogy of the Hessen family.
«Икона света» как образец «иконы в звуках» Джона Тавенера
Authors: Д.А. Еремина
Published: October 2024

Статья посвящена феномену “Icon in Sound” («икона в звуках» / «музыкальная икона» / «звуковая икона»), занимающему центральное место в миропонимании и практике зрелого периода творчества английского композитора Джона Тавенера (1944–2013). Оригинальный тип композиции, напрямую соотносимый с понятием иконы и характеризующийся религиозным типом содержания, стал результатом многолетних духовных поисков музыканта. К «иконе в звуках» Тавенер обращался с 1983 по 2000 г.: в девяти сочинениях слово «икона» фигурирует в названии, в четырех — в уточняющих авторских примечаниях. Каждая «икона» получает индивидуальное жанровое воплощение и исполнительский состав. Феномен «звуковой иконы» рассмотрен в статье на примере первого подобного опуса — «Иконы света» (1983), написанного для двойного хора и струнного трио. Произведение до сих пор не становилось предметом анализа в отечественной науке. В нем нашли отражение характерные черты данного типа композиции: опора на византийскую гимнографию, использование текстов на греческом языке, символизм мышления (тембровый, пространственный, числовой), симметрия, обращение к средневеково-ренессансным полифоническим принципам организации материала, экстатичность.

The article is devoted to the phenomenon of “Icon in Sound” («musical icon» / «sound icon»), which occupies a central place in the worldview and mature creative practice of the English composer John Tavener (1944–2013). The original type of composition, directly correlated with the concept of an icon and characterized by a religious type of content, was the result of many years of spiritual searches by the musician. Tavener addressed the “ikon in sound” from 1983 to 2000: in nine works the word “ikon” appears in the title, and in four — in clarifying author's notes. Each “ikon” receives an individual genre embodiment and a performing cast. T he phenomenon of the “ikon in sound” is considered in the article on the example of the first sample — “Ikon of Light” (1983), written for a double choir and a string trio. When translating a visual-spatial art form into an auditory-temporal one, Tavener managed to preserve the essential features of the ikon and not lose his characteristic style of writing. T he composition reflects the characteristic features of this type of composition: reliance on Byzantine hymnography, texts in Greek, symbolism of thought (timbre, spatial, numerical), symmetry, appeal to medieval-Renaissance polyphonic principles of material organization, ecstasy. In Russian musicology, the “Ikon of Light” has not been presented before.

А. С. Ляпунова — публикатор и комментатор писем А. Н. Серова
Authors: А.С. Войцешко
Published: October 2024

Известным отечественным источниковедом и текстологом Анастасией Сергеевной Ляпуновой — заведующей Отделом рукописей Ленинградской консерватории — в 1940 г. были подготовлены к публикации письма А. Н. Серова, адресованные председателю Русского музыкального общества А. А. Кирееву. В настоящей статье освещаются этапы работы исследователя с документами, дается текстологическое описание источников, кратко характеризуется содержание писем А. Н. Серова и предпосланного им развернутого научного комментария А. С. Ляпуновой.

The phenomenon of Serov’s letters demonstrates his individuality and creative thinking, thereby exposing a sensitive, vulnerable nature. A dedication to the educational cause is particularly evident in moments of acute controversy, in the selfless struggle for jus tice. The texts of the letters to Alexander A. Kireev provide insight into the state of the concert repertoire during that period, as well as the context surrounding the confrontation between two organizations — the Russian Musical Society and the Free Music School. The correspon dence commenced with the search for the truth about himself on the part of Society and acknowledgment of Serov’s contributions to Russian music. The decade-long dispute culmi nated in the critic’s detachment from the standards of public education and the popu larity of the domestic modern repertoire. As a result of the critic’s counsel, concert programmes featured previously unperformed works on the Russian stage, which subsequently delighted the audience and stimulated their interest in relevant compositions.

Письма А. Н. Серова к председателю Русского музыкального общества А. А. Кирееву, подготовленные к публикации заведующей Отделом рукописей Ленинградской консерватории А. С. Ляпуновой, раскрывают обстоятельства взаимоотношений композитора с Обществом и различными музыкантами: Даргомыжским, Балакиревым, Рубинштейном, Стасовым и др. В текстах писем содержится информация о составленных Серовым программах сезона 1870–1871 гг. (а также, частично, и 1869–1870). Предисловие («Заметка») Ляпуновой воссоздает контекст и устанавливает причины обращений композитора к адресату: не будучи привлечен к участию в Русском музыкальном обществе, Серов заявляет о своем отрицательном отношении к нему. Критике подвергались также концертные программы и их исполнение — в репертуаре концертов русской музыке отводилось слишком мало места. Привлечение Серова к составлению новых программ грядущих сезонов означала конец «десятилетней вражде», «полное примирение и сотрудничество враждующих сторон».

The famous domestic source scientist and textologist Anastasia Sergeevna Lyapu nova, Head of the Manuscript Department of the Leningrad Conservatory, prepared for publication letters by Alexander N. Serov to the chairman of the Russian Musical Society Alexander A. Kireev. The publication of the letters was accompanied by a detailed scientific commentary by Lyapunova. The letters present intriguing insights into the composer's inter actions with society and various members of the musical community, including musicians Dargomyzhsky, Balakirev, Rubinstein, Stasov and others. The texts of the letters contain information regarding the programmes compiled by Serov for the 1870–71 season (in part, also for the 1869–1870 season). In the preface (“Note”), Anastasia S. Lyapunova elucidates the context and rationale behind the composer's appeals to the addressee. Despite his lack of involvement in the Russian Musical Society, Serov makes his disapproval of the addressee known. Furthermore, the concert programmes and their performance were also subjected to criticism. It was argued that insufficient space was allocated in the repertoire of concerts to Russian music. However, Serov's involvement in the compilation of new programmes for the forthcoming seasons signified the conclusion of a decade-long feud, resulting in com plete reconciliation and collaboration between the previously estranged parties.
Determination of the experimental minimal formula of metal-organic frameworks

Published: October 2024

Metal-organic frameworks have emerged as one of the most promising classes of materials in the last decade with potential applications in many domains of science. However, the determination of their precise chemical composition has been often overlooked, although it is crucial for many advanced applications such as catalysis or drug delivery. Here, we propose a rigorous yet simple protocol for the accurate determination of a MOF's minimal formula. By integrating quantitative NMR and UV-Vis spectroscopy data alongside TGA analysis, we construct the complete minimal formula using MOF-808 as a model material. We show the critical influence of the MOF digestion method and of the NMR measurement parameters on the accuracy of the minimal formula. Furthermore, we provide a quantitative method for determining the amount of residual chloride that originates from the precursors used in MOF synthesis, which has been often ignored in minimal formulae determination. In order to help improve the reproducibility and accuracy of MOF applications, we introduce the concept of room temperature molar mass that can deviate significantly from the idealized molar mass. Although the determination of the MOF experimental minimal formula is often perceived as a complex and tedious task, the general methodology presented here is straightforward and can be achieved with very simple equations and procedures.
La transición energética y la conceptualización de los procesos en ingeniería
Authors: Castro Pelaez Karem Johanna , Vélez Restrepo Juan Manuel , Montoya Restrepo Iván Alonso
Published: October 2024

La transición energética es un reto global que implica reducir las emisiones de Gases de Efecto Invernadero (GEI) y garantizar la seguridad energética para cumplir con las Contribuciones Nacionales Determinadas (NDCs). La Agencia Internacional de Energías Renovables (IRENA) define esta transición como el camino hacia la transformación del sector energético global, sustituyendo los combustibles fósiles por energías no contaminantes para el año 2050. Esto requiere una sustitución gradual de los combustibles fósiles y un aumento significativo de la participación de energías renovables, lo cual plantea grandes desafíos y oportunidades desde la ingeniería. Este artículo aborda estos desafíos tecnológicos, económicos y sociopolíticos, destacando la necesidad de cambiar la conceptualización de los procesos en ingeniería. Se propone la integración del análisis exergético como una metodología clave para optimizar la eficiencia energética y reducir el impacto ambiental de los procesos industriales. Además, se presenta un modelo de gestión del conocimiento con estrategias didácticas basadas en la metodología de Bela H. Banathy para la enseñanza de la ingeniería, enfocadas en la actualización del concepto de proceso y la preparación de los futuros ingenieros para enfrentar los retos de la sostenibilidad y la transición energética, así como para su vida como profesionales. La implementación de estos cambios es esencial para desarrollar procesos de ingeniería que sean resilientes y sostenibles a largo plazo

Authors: Valencia Palacio John Andersson , Rodríguez Velásquez Elkin
Published: October 2024

El problema de secuenciación en configuraciones productivas tipo Job Shop con bloqueo (Blocking Job Shop Scheduling Problem-BJSP), es una extensión del problema convencional en la cual una máquina permanece bloqueada con un trabajo, hasta que dicho trabajo inicie su procesamiento en la siguiente máquina. El BJSP es considerado Strongly-NP hard, lo cual implica que es difícil encontrar la solución óptima del problema en la medida que aumentan la cantidad de trabajos y máquinas en la configuración. Adicionalmente, los métodos actuales de búsqueda de soluciones presentan problemas significativos para encontrar la solución óptima e incluso, para encontrar soluciones factibles al problema. En este trabajo se propone un algoritmo genético (AG) que permite encontrar y evaluar soluciones factibles para el BJSP. Inicialmente se hace una descripción del problema considerando variables, parámetros, función objetivo y restricciones. Posteriormente, se hace una descripción de la metodología que permite construir soluciones siempre factibles al BJSP, y del algoritmo genético propuesto. Finalmente, se usa el algoritmo genético propuesto para encontrar soluciones al conjunto de problemas de las instancias de Lawrence con el objetivo de minimizar el makespan (Cmax). Se muestran los resultados obtenidos y las desviaciones con respecto a los resultados registrados en la literatura

Published: October 2024

La atracción de los niños hacia las carreras de STEAM (Ciencias, Tecnología, Ingeniería, Artes y Matemáticas) se ha convertido en una necesidad y en un gran reto para las universidades. Es frecuente que los niños, y especialmente las niñas, expresen en algún momento de su vida que no son buenos para las matemáticas, que no les gustan las ciencias, que no se les ocurre nada creativo. Sin embargo, aman la experimentación: el juego, las adivinanzas, los retos. En este contexto, la alianza entre la Universidad de Los Andes y SLB han concebido CREA, un espacio creativo destinado a niños, donde la magia del aprendizaje STEAM cobra vida. El espacio combina dos verbos fundamentales: crear y creer, permitiendo que los niños pasen de la imaginación a la realización en un espacio físico de trabajo equipado con tecnología de vanguardia: impresoras 3D, drones y sistemas de realidad virtual. En este artículo se presenta la estructura de CREA, el tipo de actividades propuestas para uso de espacio y los resultados más relevantes que se han obtenido
Plataformas interactivas y enseñanza de la química

This research aims to dig deeper into the relationship between mood, emotions, and societal legal compliance. The urgency of research lies in understanding the role of individual moods and emotions in legal compliance in society. Stability, security, and justice in society depend primarily on the level of compliance with the law, and this research highlights that an individual's mood and emotions can be a crucial factor in such compliance behavior. The focus of this research lies in the approach taken in analyzing the relationship between mood, emotions, and legal compliance, in contrast to previous research, which focused more on external factors such as law enforcement or socio-economic characteristics. This research approach method is sociological juridical and focuses on qualitative data. This research provides new insights into how these psychological factors influence legal compliance behavior in society. The finding is that positive moods, such as happiness and peace, promote higher legal compliance, while negative moods, such as anxiety or anger, can reduce legal compliance. The conclusions of this research emphasize the importance of considering psychological aspects in designing effective law enforcement policies and strategies. Understanding how mood and emotions influence legal compliance behavior can improve legal compliance and create a safer and more stable environment.

Published: October 2024

This study examined the allocation of financial aid funds from the Banda Aceh Regional Government Budget (APBK) to Local Political Parties X and Y in Banda Aceh. This study conducted empirical juridical research and presented the findings of field research using two analytical frameworks: Legal Effectiveness theory and Siyasah Maliyah Fiqh theory. It focused on local political parties since they represent a unique kind of democracy in the Aceh region. From the standpoint of legal effectiveness theory, the findings of this study suggest that the supporting facilities in the form of financial aid and legal factors are adequate and suitable. Nevertheless, barriers remain present within law enforcement, society, and culture. From the accumulated results of the components of the theory of legal effectiveness, a fiqh siyasah maliyah perspective is obtained. Thus, it can be concluded that the principles of ownership and management are still hampered by transparency, accountability, and openness of information to the community. The principle of abuse and corruption is already working well, but the accuracy of targeting financial funds must be improved The people's benefit has not been completely realized as a result of the aid use not being targeted.. The principle of amar ma'ruf nahyi mungkar has also not been fully implemented because it is hampered by a crisis of public trust, the party's understanding of regulations, and the infrastructure supporting transparency and accountability.

Objective: To evaluate the intervention effects of seated Baduanjin exercise on patients undergoing maintenance hemodialysis (MHD). Methods: A total of 108 MHD patients admitted between July 2022 and July 2023 were selected. They were randomly assigned into two groups: the experimental group, with 55 patients, who received seated Baduanjin exercise combined with leg exercises during dialysis; and the control group, with 53 patients, who only performed leg exercises during dialysis. The psychological state, fatigue symptoms, quality of life, and sleep quality scores were compared between the two groups, and exercise endurance was recorded. Results: After the intervention, the psychological state scores in the experimental group were lower than those in the control group, the fatigue symptom scores were lower, the quality of life scores were higher, the sleep quality scores were lower, and the exercise endurance was higher (P < 0.05). Conclusion: Seated Baduanjin exercise can improve the negative psychological state and fatigue symptoms of MHD patients, enhance their quality of life and sleep quality, and effectively increase their exercise endurance.

Objective: To systematically evaluate the effect of modified length of gastric tube implantation in stroke patients. Methods: Randomized controlled studies on the effect of narrative therapy on negative emotions of malignant tumor patients were published in PubMed, EMbase, Web of Science, Cochrane Library, CNKY. Wanfang Data, VIP Database and CBM disc from database establishment to May 2021. RewMan 5.2 software was used for the meta-analysis. Results: Ten articles were included, involving 1140 patients in total. Results of meta-analysis showed that improved length of gastric tube implantation could reduce the incidence of aspiration pneumonia in stroke patients with enteral nutrition [OR = 0.18, 95% CI (0.10, 0.31), P < 0.00001], reduce gastroesophageal reflux rate (OR = 0.13, 95% CI (0.04, 0.38), P < 0.0002], the incidence of aspiration (OR = 0.23, 95% CI (0.11, 0.38), P < 0.00001], the incidence of abdominal distension and diarrhea (OR = 0.13, 95% CI (0.06, 0.28), P < 0.00001], the incidence of choking cough (OR = 0.20, 95% CI (0.07, 0.61), P < 0.005], but no difference between the two groups in terms of reducing gastric residual (OR = 0.10, 95% CI (2.40, 2.60), P = 0.94]. Conclusions: The modified length of the gastric tube can replace the traditional length of the gastric tube in the application of stroke patients, can reduce the complications of enteral nutrition, is safe and feasible. However, due to the limitation of the quality and quantity of the included studies, we should be cautious about the results of this meta-analysis and expect to carry out more large-sample and high-quality randomized controlled trials for demonstration.

Published: October 2024

Вооруженные конфликты продолжают вызывать деградацию и разрушение окружающей среды во всем мире. Устойчиво функционирующие природные экосистемы имеют решающее значение для благополучия человека и устойчивого развития. Вооружённая борьба оказывает крайне негативное воздействие на структуру и функционирование экосистем. Антропогенное воздействие вооружённой борьбы на среду обитания, загрязнение природных ландшафтов, изменение структуры и объема потоков экосистемных услуг способствуют утрате биоразнообразия. Последствия вооружённой борьбы сохраняются в течение многих лет или десятилетий после окончания войн, оставляя неизгладимые последствия для жизни местного населения. Целью статьи является заполнение критического пробела в существующей литературе, посредством описания инновационных стратегий дистанционного наблюдения за состоянием природных экосистем, находящихся в зоне вооружённой борьбы. Автором представлена: оценка влияния программ постконфликтного восстановления экосистем на стратегии достижения ЦУР; тепловая карта взаимосвязи типа экосистемы с социальными проблемами, решаемыми в рамках мероприятий по восстановлению природных экосистем; тепловая карта воздействия различных типов природных экосистем на процесс реализации стратегии достижения ЦУР при реализации мероприятий по восстановлению природных экосистем. В статье представлена тепловая карта существенности данных, получаемых при осуществлении дистанционного зондирования земли, применяемых для разработки стратегий постконфликтного восстановления, направленных на достижение ЦУР, и тепловая карта существенности данных об историческом и фактическом состоянии природных экосистем, находящихся в периметре вооружённого конфликта, получаемых при анализе краудфандинговых данных социальных сетей при реализации программ постконфликтного восстановления.
The Impact of Alai Suri Kurdayeti Magazine in Disseminating National Awareness
Authors: Mahmood Rasheed Sirwan , Kareem Saeed Mohammed
Published: October 2024

This paper, titled "The Impact of Alai Suri (Red Flag) Kurdayeti Magazine on the Propagation of National Awareness," delves into an examination of the content within Alai Suri Kurdayeti Magazine during the period of the mountain struggle and the revolutionary era, spanning from 1981 to 1982. Despite the protracted history of the Kurdish people's struggle for their national rights, the establishment of a comprehensive national identity remains an indispensable intellectual and vital requirement within Kurdish society, intrinsically tied to the notion of national consciousness.
The manifestation of a national identity fundamentally hinges on shared national principles, a common language, culture, religion, history, collective aspirations, and unified political and legal principles, all of which necessitate a heightened state of national consciousness. Throughout the history of the Kurdistan liberation movement, diverse strategies have been employed to attain this identity, with media engagement serving as one prominent avenue. During a particularly sensitive period in Kurdish history within South Kurdistan (1981-1982), the Kurdish Socialist Party (PASOK) issued Alai Suri Kurdayeti Magazine. This publication, apart from accomplishing its political objectives, aimed to acquaint Kurdish society with various facets of life and intellect. Its purpose was to cultivate national thought and consciousness while alerting the community to the imminent threats they faced.
