Authors: Khvostov A.A. , Barabash D.E. , Anikin I.V.
Published: April 2024

Efficiency of film compositions with a complex of inhibitors at protection of equipment against corrosion is shown. The leading role of diffusion in formation of a protective layer on a substrate is revealed. Relevance of development of model of diffusion of inhibitors of corrosion to a substrate at the expense of the most hostile environment is proved. The specified model will provide calculation of concentration of inhibitor for various types of hostile environment (alkaline, acid) and establishment of necessary thermodynamic characteristics of a polymeric basis. The film on the basis of latex DMMA containing contact and flying water-soluble inhibitors of corrosion was investigated. Methyl Methacrylate latex belongs to the hydrophilic polymers differing in abnormal diffusion. Speed of diffusion of vapors of water through latex films up to 3 mm thick is experimentally established. Assumptions are entered and the mathematical model of an element of a polymeric film added with entry and boundary conditions according to service conditions is developed. Experimental values of the functions describing diffusion of water and inhibitor approximated the bicubic interpolation polynomial realized by standard algorithm of MatLab library. The decision is carried out in a CFD package of modeling Comsol Multiphysics, at the same time the computing grid contained 2128 elements. It is defined that diffusion is complicated by the conformational transformations of macromolecules of a polymeric matrix directly depending on temperature. Change of coefficient of diffusion of a film at endurance in water owing to change of a conformational condition of macromolecules of a film from temperature is experimentally established. It is established that the current of the first minutes is established a gradient of temperatures which results in stationary value of medium-volume temperature of a film. Water diffusion as inertial process establishes a gradient of concentration with orientation of lines of current towards a zone of defect of a film on a substrate. The gradient of concentration of inhibitor grows more slowly, than concentration of water that is caused by initiation of formation of the "inhibitor + water" complex. In process of inhibitor exhaustion directly in a defect zone, its diffusion from the nearby intact areas is excited that raises a functional stock of an anticorrosive covering. Results of comparison of the data on quantitative structure of a polymeric film received experimentally and calculation for model are given, their convergence is shown.

Authors: Harvey Steve , Wang Si , Kelly Connor
Published: April 2024

This article presents an illustration from an online creative arts project in which different languages were used by participants of a small group within fairytale-movement-music improvisation. The participants, consisting of creative arts therapists and students from different regions of the world, including Canada, New Zealand, and China, represented various world cultures and spoke different primary languages. A session was selected by the authors as it represented an example of a natural experiment that emerged from the global arts-based response to the COVID-19 pandemic, offering a unique case study of how art expression can contribute to communities during crisis events. The purpose of the article is to provide suggestions to guide future groups in the use of arts-based improvisation that might improve communication among participants who do not share a common primary language but have shared complex emotional experiences. In addition, the article includes a review of related education, dance, and drama projects that involve different languages and cultures as well as a drama therapy project that addresses the improvised dramatic communication of complex emotional experiences. Furthermore, the article offers a detailed review of one session from the project using an arts-based inquiry and suggests ways to apply multilingual imaginative storytelling within the communication of groups in community and educational cross-cultural settings.

Проаналізовано стан наукових досліджень Schisandra chinensis (Turcz.) Baill. – цінної лікарської та плодової ліани, перспективної для вирощування як у приватному садівництві, так і в промислових масштабах. Проведено анатомо-морфологічниі дослідження стебла та кореневища лимонника китайського за умов інтродукції в Національному ботанічному саду ім. М. М. Гришка НАН України (Правобережний Лісостеп України). Анатомічні дослідження виконували з використанням мікроскопу XSP-146TR. Виявлено особливості анатомічної будови стебла і кореневища дводомних і однодомних рослин лимонника, відібраних в різні фази розвитку. Наприкінці серпня відзначено істотне нагромадження крохмальних зерен у паренхімі кори, серцевинних променях та перимедулярній зоні однорічних пагонів лимонника, які в період виходу рослин зі стану спокою майже відсутні. У багаторічних пагонів, на відміну від однорічних, встановлено більшу кількість шарів клітин фелеми перидерми (подекуди до десяти) та інтенсивнішу насиченість клітин суберином, який запобігає втраті вологи рослинними тканинами. Відзначено, що будова кореневища рослин лимонника китайського в поперечному перетині повторює будову стебла, але водночас було виявлено і певні його анатомічні особливості, які стосуються слабко розвиненої перидерми, що складається з 2-3 шарів суберинізованих клітин, відсутності коленхіми та наявності великої кількості ефіро-олійних включень у паренхімі кори, яка значно товща порівняно з стеблом. Встановлено, що пагони рослин лимонника з маточковими квітками вирізняються меншою кількістю включень з ефірною олією, порівняно з однодомними рослинами, що може бути пов'язано з їх інтенсивнішим плодоношенням, тому, як фармакологічну сировину, краще використовувати стебла та кореневища саме однодомних рослин лимонника. Зроблено припущення, що виявлений значно вищий ступінь розвитку склеренхімних елементів флоеми та перидерми стебла, порівняно з кореневищем, може бути однією з причин низької регенераційної здатності стеблових живців S. chinensis під час вегетативного розмноження рослин шляхом укорінення здерев'янілих живців. Наголошено на важливості дослідження для подальшої селекційної роботи з лимонником китайським та вирішення проблеми вирощування посадкового матеріалу.
„Ihr Völker lernt gefährlich leben.“ Mit Katastrophenmusiken auf dem Weg zum Frieden?
Authors: Besthorn Florian
Published: April 2024

The central question posed in Jörg Widmann's oratorio Arche (2016/2017) is how a society can find new encouragement for the establishment of a more equitable world in times of crisis. This article examines the five movements of the composition and shows how Widmann's intertextual references contribute to conveying and answering this question: In both the text and the music, the composer refers to the European cultural heritage of several centuries, evoking horrific scenarios as well as utopias. However, the «golden path» elaborated in Widmann’s work does not emerge as expected between these contrasts; rather the way is left open for a future society to discover a path for itself without relying on a higher authority. Following the journey of the biblical Ark, the audience experiences various situations in which they are confronted with the necessity to find solutions for peaceful human coexistence. At the end of the oratorio, Widmann's "Dona nobis pacem" presents a plea for peace which remains unanswered, however; for who would be able to hear its song if mankind is not willing to listen?
Die Welt in einem neuen Licht sehen – Gustav Mahlers Spätwerk als Symptom einer persönlichen Krise?
Authors: Pensa Martin
Published: April 2024

The late work of Gustav Mahler is often interpreted in connection with the composer’s crisis of 1907, when he lost both his daughter Maria Anna and his job as the director of the Vienna Court Opera, and furthermore was diagnosed with a heart failure. Although some stylistic changes affecting Das Lied von der Erde, as well as the ninth and tenth symphonies may seem obvious when compared to his compositions before 1907, it remains quite complicated to describe these late works as symptoms of this time of crisis leading to the composer’s death in 1911. The common narrative is based on the assumption that already during the composition of his three last symphonies, Mahler had largely resigned from the world – a highly debatable thesis. In this essay, I would like to show that a crucial characteristic of Mahler’s ninth symphony is its retrospective view of earlier compositions, both his own and those of other composers to whom he felt committed, creating a network of intertextual relations that reflects this process of looking back from a point of crisis.
Voicing Stigma in Performances: An Account of Mad:Ness (2023)
Authors: Sikau Lea Luka Tiziana , Jobbins Nat
Published: April 2024

How is madness powerfully voiced in music? For one, we are musicians who need no convincing of the clarity of voicing beyond words; the task is listening properly. For another, we are people who intimately know the harm that can be inflicted by pathologizing notions of mental illness, especially when diagnosis and medical treatment are so easily grasped as practices of healing and care. Seeking to let Madness speak otherwise, rather than to be spoken for or about, we playfully reflect with our recent performance “Mad:Ness”, hosted by Tonali in Hamburg in March 2023.

The Role of TNF-Alpha in the Wound Healing Process: Molecular and Clinical Perspectives - A Systematic Literature Review
Authors: Yusuf Khaidir
Published: April 2024

Wounds are conditions of damage and partial loss of body tissue caused by physical trauma, sharp objects, blunt objects, temperature fluctuations, chemical exposure. Wound healing is a complex interaction between cells, cytokines, mediators, and blood vessels as a natural physiological response to tissue damage. TNF-α has a crucial role in the wound healing process, facilitating body immunity, immune cell mobilization, fibroblast cell proliferation, keratinocytes, and growth factor expression. Although TNF-alpha has benefits in the early stages of wound healing, excessively high levels or a sustained inflammatory response can lead to problems, such as excessive scar tissue formation or blockages, which can impede the wound healing process. This study utilized the PRISMA-ScR (Scoping Review) protocol. A review was conducted of articles discussing the Role of TNF-Alpha in the Wound Healing Process: Molecular and Clinical Perspectives within the last 10 years. Literature search in this study using PubMed, ScienceDirect, Elsivier and Google Scolar databases Search using English, abstract and full text. After searching with the keywords: The Role of TNF-Alpha, 19,022 articles were found. The search continued using the keyword The Role of TNF-Alpha in the Wound Healing found 346 articles. The last search using the keyword The Role of TNF-Alpha in the Wound Healing: Molecular and Clinical found 26 articles. TNF-α plays an important role in the early stages of cutaneous wound healing, significantly delayed after day 3, but not by day 7. TNF-α has a crucial role in the early stages of skin wound healing, and its administration is recognized to have a positive impact on the healing response, which may pave the way for innovative strategies to address chronic skin wound healing problems.

Published: April 2024

Introduction: Cases of neuroendocrine tumors (NET) can occur in various organs, generally in the form of gastroenteropancreatic (GEP-NET) and pulmonary tract (PNET). The incidence of thymic neuroendocrine tumors (TNET) is rare, accounting for less than 5% of thymic and mediastinal malignancies, and 0.4% of all neuroendocrine tumors.
Case presentation: A 57-year-old man came to RSUP Dr. Mohammad Hoesin Palembang with complaints of coughing, bluish and curved blood vessels in the chest, and shortness of breath during activities that have been getting worse for six months. CT scan showed a tumor measuring 18.6 x 11.7 x 11 cm in the anterior mediastinum and pressing on the superior vena cava and abdominal aorta. TTNA and core biopsy with CT guidance showed NET Grade 2, mitoses 6/2 mm2, positive tumor cells with immunohistochemistry for synaptophysin, chromogranin, CD 56, AE1/AE3, and Ki67 9%. The patient received paclitaxel and carboplatin chemotherapy for 6 cycles.
Conclusion: The prognosis for atypical carcinoid patients is 20-80% for a 5-year survival rate. Appropriate patient management is needed to improve the outcome of patients with primary thymic atypical carcinoid (NET, grade 2).

Authors: Ajao Owolabi Sunday , Ifeanyi Ogbebor Peter , Claude Karekezi Jean
Published: April 2024

A well-developed financial system plays an important role in the economic performance of a country. Thus, the role of financial development and its functions in stimulating economic performance is concrete. However, the economy of Rwanda has experienced an accelerated inflation rate in recent times. The study adopted an ex post facto design to ascertain the effect of financial development on the inflation rate in Rwanda over a period of 12 years. Time series data were collected from 2011-2022. Ordinary Least Squares (OLS) were also adopted. The findings revealed that financial liberalization, domestic credit to the private sector, monetary policy rate, market capitalization, and all share indexes jointly did not influence the inflation rate in Rwanda (Adj.R2 = 14.39%, p = 0.3524 > 0.05, F-stat = 1.3699). The study concluded that financial development did not affect the inflation rate in Rwanda during the period under review. The study recommends that the government of Rwanda should improve on financial development through improving macroeconomic factors such as liberalization of the financial sector and strengthening the channels of credit to the private sector.
On Some Aspects of European Security and Defence in the Context Of War in Ukraine
Authors: Ivančik Radoslav
Published: April 2024

The European security environment is currently significantly affected by Russian aggression against Ukraine. However, right from the start of the war, the European Union and its member states acted decisively, they unequivocally condemned the Russian invasion of Ukraine and began to help it politically, economically, humanitarianly and by supplying military equipment, weapons, ammunition, and training members of the Ukrainian armed forces. And although no European member state of the European Union or the North Atlantic Alliance has been attacked, the ongoing conflict negatively affects European stability and disrupts the European security and defence system. That is also why the authors, using relevant scientific methods and approaches within the framework of interdisciplinary research, deal in the article with some selected aspects of European security and defence in the context of the conflict in Ukraine. They point out how Russian aggression has influenced discussions about the roles of the European Union in ensuring security and defence on the European continent, shed light on the Union's security and defence policy, deal with issues of European strategic autonomy and related relations between the EU and NATO, and at the end of the article indicate challenges, which are closely related to European security and defence in the context of the war in Ukraine.

Authors: Hayati Wirda , Suwarni Suwarni , Jasna Nova Riska , Yusuf Meutia
Published: April 2024

Background: The nurse's verbal and non-verbal communication greatly affects the readiness of the patient and the patient's family to undergo surgery. Unclear communication causes misperceptions and the emergence of communication barriers in the nurse-client interaction process. The limited time and information provided are the causes of communication barriers in the client care process. This of course greatly affects patient care, especially in conditions that require intensive care. Methods: This study aims to determine the relationship between verbal and non-verbal communication between nurses and perceptions of communication barriers in families of pre-surgery patients in the intensive care unit, with a correlation design using a Cross Sectional study approach. The number of samples was 95 families of preoperative patients in the intensive care unit using purposive sampling technique. Results: 51.6% of nurses' verbal communication was good, and 50.5% of nurses' nonverbal communication was good, and there were no communication barriers between nurses and patients' families (54.7%). There was a significant relationship between nurses' verbal communication with perceptions of family communication barriers in pre-surgery patients in the intensive room (P=0.001) and there was a correlation between nurses' nonverbal communication with perceptions of family communication barriers in pre-surgery patients in the intensive room (P=0.002). Recommendation: Nurses are expected to continue to communicate effectively verbal and non-verbal with patients and families to prevent barriers in communication.

Authors: Eiriz Parra Martín Miguel , Arbas Redondo Emilio
Published: April 2024

Con la llegada de la reperfusión, especialmente con la intervención coronaria percutánea, la mortalidad y la incidencia de complicaciones mecánicas del infarto agudo de miocardio han disminuido considerablemente. El tiempo desde el comienzo de los síntomas hasta la reperfusión es un factor fundamental; su retraso favorece la aparición de ruptura de la pared libre, del septum interventricular o del músculo papilar. Actualmente, la ruptura del septum interventricular es una complicación rara pero devastadora que, a pesar de un tratamiento médico y quirúrgico oportuno, presenta una mortalidad alta.

Las prótesis valvulares constituyen el tratamiento definitivo de muchas valvulopatías avanzadas; sin embargo, no están libres de complicaciones. Una de ellas es la formación de seudoaneurismas, un hallazgo infrecuente pero probablemente infradiagnosticado tras una sustitución valvular aórtica. La ecocardiografía presenta frecuentemente limitaciones en el estudio de esta patología, muchas veces, debido a los artefactos que causan las estructuras metálicas de las propias prótesis. El estudio anatómico mediante tomografía computarizada nos puede ayudar en estos casos a determinar su geometría y su relación con otras estructuras; identificar situaciones de riesgo, y a planificar el acto quirúrgico de reparación. En este artículo presentamos un caso particular de seudoaneurisma dependiente del tracto de salida del ventrículo izquierdo de aparición tardía décadas después de la cirugía cardíaca.

Authors: Aylmer Roberto , Aylmer Mariana , Dias Murillo
Published: April 2024

This research explores socialization in the Brazilian public sector (BPS) and Petrobras, the largest semi-public company in the country. It investigates the challenges faced by new employees and the factors influencing socialization in the public sector. Using Behavioral Event Interviews with experts, the study aims to understand how dissatisfied employees handle their relationship with work and the company when they perceive no risk of being fired. It also explores the situation when new employees reach their limit of coping but choose not quitting the job due to the high investment and benefits. The study also examines how the socioeconomic context influences socialization in the public sector, as new employees expect to spend their entire productive years in the company until retirement.

Authors: Conol Rosalie A. , Pit Noel N.
Published: April 2024

The presence of children-at-risk (CAR) in some of the Filipino home challenges parenting. Using a case study design, this study explored select parents-beneficiaries of Pantawid Pamilyang Pilipino Program (4Ps) in Ozamiz City ways of parenting Children-at-Risk (CAR).   Purposeful sampling was employed to choose the 13 participants. Data were collected from multiple sources such as Focus Group Discussion (FGD), In-depth Interview (IDI), Key Informant Interview (KII), and material artifacts.  Trustworthiness was observed.  Reflexivity statement was written to disclose the role of the researcher. To determine the codes, categories, and themes, data were analyzed using HyperResearch software.   The findings highlight the following themes such as corrective-supportive parenting, ways of addressing CAR’s transitional struggles, and establishing open communication. From these themes, it can be inferred that parenting styles may differ from other parents because parenting children-at-risk has neither set of techniques nor gold standard.  Parents need to be skillful, creative, and be attentive listeners to the unspoken feelings and desire of their children.  Future research may be conducted to determine patterns of parenting and children’s behavior in other cities and municipalities with cases of CAR.

The study used a questionnaire answered by 347 participants from various courses. Findings show that the participants appeared a strong awareness of their information needs, indicating clarity in what they were looking for. They understood the importance of checking and confirming information to make sure it is reliable. The study also found that participants actively searched for information, considering their thoughts, feelings, and experiences in the process. Importantly, the participants demonstrated high skills in information literacy, including evaluating information, using effective search strategies, accessing online databases, and citing sources correctly. This suggests that they have a good understanding of key concepts related to information literacy and are proficient in using these skills. The study concluded that there is a significant connection between students' information needs, how they search for information, and their information literacy skills. Those who have higher information needs and actively seek information are more likely to have better information literacy skills. Overall, the research highlights the complex relationship between these factors in the academic environment.

Published: April 2024

In this study, zeolite was used as a catalyst in a catalytic cracking reaction of waste cooking oil, which generates compositions similar to gasoline. This reaction was catalyzed by batch distillation of WCO in a hydrothermal reactor with zeolite catalyst synthesized using local clay sediment. The catalytic cracking was carried out under ambient conditions using 100-ml distillation apparatuses placed on a heating mantle and 50g of oil-added variable catalyst loading from 2 to 10 Wt% with zeolite as catalyst. The heating rate, residence time, and catalyst loading influenced the product yield. The physicochemical properties of the product, such as the density, the flash point, and the kinematic volumetric viscosity, were examined for fuel suitability. Chemical gas chromatography-mass spectrometry (GC-MS) determined the chemical composition of the compounds present in the cracked product. The overall study showed that the product's optimum zeolite loading, cracking temperature, and cracking rate were 8 wt%, 380 oC, and 0.0048 min-1, respectively. The study on zeolite catalytic cracking revealed that local clay synthesizes the zeolite catalyser, which is effective in WCO catalytic cracking for liquid fuel formation.
