Authors: V. A. Mendes Marcos , N. Alves Vanessa
Published: May 2024

A utilização de resíduos de mineração como adsorventes vem sendo muito abordada na literatura. Esses materiais normalmente são descartados em pilhas ou barragens, e se reutilizados para outras finalidades, podem significar redução de passivos ambientais para o setor de mineração. Neste sentido, este estudo objetiva caracterizar e avaliar a capacidade de adsorção frente a íons manganês em diferentes faixas de pH de resíduos de mineração tais como rejeito magnético, rejeito de flotação e lama. Os melhores resultados de adsorção foram obtidos em pH alcalino, sendo que a lama apresenta melhor potencial adsortivo em relação aos demais materiais, possivelmente devido a suas propriedades físicas e químicas.

Authors: Panjaitan Endy Desmanto , Ida Aju Kusuma Wardani  , I Gusti Ayu Indah Ardani
Published: May 2024

Introductions: Based on a 2015 United Nations Children's Fund (UNICEF) report, violence against children is widespread in Indonesia; 40% of 13–15-year-old children reported being physically assaulted at least once a year, 26% reported being physically abused by a parent or caregiver, and 50% reported being bullied at school. Case: A 23-year-old female patient, Hindu, Balinese, unmarried, and unemployed, came alone to the psychiatric polyclinic of Wangaya Hospital. From history taking, there was dizziness, anhedonia, impaired attention, reduced self-esteem and confidence, guilt and uselessness, reference ideas, somatic delusions, relationship mood, logorrhea and flight of ideas, a history of mixed-type insomnia, and excessive energy. In a general examination, there were icteric sclera and palpable enlargement of the spleen (Schuffner 4). Neurological examination within normal limits. Discussion: The patient has bipolar disorder, caused by a traumatic experience in childhood. The patient was found to have a history of repeated treatment; she was initially diagnosed with bipolar disorder and received Depakote 250 mg and Clobazam 10 mg. Then, the patient came for treatment again at Wangaya Hospital on August 30, 2021, because of a headache and was diagnosed with bipolar affective disorder, with the current episode being moderately depressive with somatic symptoms. Conclusion: Traumatic childhood events are a risk factor for bipolar disorder. In addition to poor clinical presentation, the early onset of bipolar disorder is also an aggravating factor for symptom recurrence. Polycythemia vera can be a complicating factor in the recovery and relapse of bipolar disorder.
Urinary Incontinence Associated with Sertraline use in a Young SSRI-Naí¯ve Female Patient: a Case Report
Authors: Anna Elissa
Published: May 2024

Introductions: Urinary incontinence is a side effect of several antidepressants, especially those in the SSRI and SNRI groups. Sertraline, a popular SSRI effective against a wide range of mental disorders, is one such drug with a clear association with a new onset of UI. Case: A 20-year-old Indonesian Chinese woman, presenting with mixed anxiety and depressive symptoms, was initially treated with sertraline 50 mg. She experienced an acute onset of urinary urgency and a loss of bladder control. These symptoms resolved upon discontinuation of sertraline. She was then given 10 mg of fluoxetine, and she noted that the urinary problems did not return. The medication was gradually tapered up to 40 mg/day with no remarkable adverse events. Discussions: Sertraline tends to stimulate micturition through effects on M3 muscarinic receptors on the bladder's detrusor muscle and inhibition of the dopamine transporter in the central nervous system. On the other hand, fluoxetine acts antagonistically on 5-HT2C, inhibiting the voiding reflex and promoting urinary continence. Therefore, though both are SSRIs, sertraline and fluoxetine may exhibit different, clinically meaningful effects. Conclusions: Clinicians need to have a greater awareness of urinary incontinence as a side effect of sertraline, as it impacts patients' adherence and quality of life. When possible, switching to fluoxetine is recommended for patients with urinary problems in the event of sertraline use.

Published: May 2024

Introduction: Medical students have higher psychological pressure compared to students from other majors. Excessive levels of stress can cause physical and mental problems, lower self-esteem, and interfere with academic achievement. Stress has a significant correlation with academic grades. Objective:  This study aims to determine the relationship between stress levels and academic scores Methods: This research is an observational analytic study with a cross-sectional design to analyze the relationship between perceived stress scale and academic scores. Perceived Stress Scale were used to determine stress level and spearman correlation were used to correlate stress level with GPA Results: No variable with a Spearman correlation coefficient above 0.2 was found, so it can be seen that none of the variables has a correlation with GPA. But income per capita has a significant p-value. Discussion: The stress level score with the GPA score has a Spearman correlation of -0.089. The correlation shows an insignificant relationship. This shows that the level of stress shown through the Perceived Stress Scale does not have a significant effect on the academic scores of Airlangga University medical students. Sohail's research (2013) found similar results where most students with stress still passed the exam but there were a small number of students with severe stress who failed. This is different from the results of Kumar et al. (2014) who found that stress levels have a negative effect on academic performance. Conclusion: In this study, no correlation was found between stress levels and academic scores.
АНАЛІЗ МІКРОБНИХ ЛЕТКИХ ОРГАНІЧНИХ СПОЛУК У ПОВІТРІ ПРИМІЩЕНЬ. ВАЛІДАЦІЯ МЕТОДУ ТЕРМОДЕСОРБЦІЙНОЇ ГАЗОВОЇ ХРОМАТО-МАС-СПЕКТРОМЕТРІЇ

Метою цього дослідження була валідація методу вимірювання мікробних летких органічних сполук (мЛОС) у повітрі приміщень за допомогою термодесорбційної газової хроматографії та мас-спектрометрії (ТД-ГХ/МС). мЛОС, які часто виділяються пліснявими мікрорганізмами, можуть негативно впливати на якість повітря в приміщенні та здоров’я людей. Процес валідації оцінює точність, правильність, лінійність, діапазон, межі виявлення та кількісного визначення, селективність, робастність та стабільність методу. Метод аналізує 12 різних мЛОС і три немікробних ЛОС. Проведено порівняння різних сорбентів, зокрема Tenax TA та Carbograph та їх комбінації. Результати показують варіативність лінійності, точності та правильності. Рекомендовано використовувати нові комбіновані Tenax TA+Carbograph пробовідбірники для зразків та пропонується переглянути метод для таких речовин, як диметилсульфід. Також обговорюється чутливість методу до температури десорбції та стабільність зберігання зразків протягом трьох тижнів.
ДОСЛІДЖЕННЯ МОЖЛИВОСТЕЙ РЕГЕНЕРАЦІЇ МЕМБРАН ЗВОРОТНОГО ОСМОСУ

Технології баромембранного очищення води є найпопулярнішим і найдоступнішим рішенням для вирішення цього питання і створення можливості постачати якісну питну воду у кожен будинок і родину завдяки побутовим установкам зворотного осмосу. Методи обробки води і процеси доочищення водопровідної води можуть допомогти позбутися широкого спектру забруднюючих речовин, що входять до її складу. Саме мембранна технологія є однією з найбільш широко впроваджених технологій очищення води.Звоторній осмос в даний час вважається найбільш надійною технологією опріснення води та очищення стічних вод завдяки високій енергоефективності, простому дизайну, високим виробничим потужностям та високим темпам видалення забруднень. Проте забруднення мембрани є найвразливішим елементом установок зворотного осмосу. Основні неорганічні речовини, які утворюють осад на мембранах - сульфати, фториди, залізо, карбонати, кальцій, магній і кремнезем. Крім того, мембрана може забруднюються колоїдними частинками, які присутні у вихідній воді. Колоїдні забруднення включають неорганічні забруднювачі і органічні молекули. Мул, глина, кремнезем і оксиди металів складають більшість неорганічних колоїдів в природній воді, тоді як білки, олії та гумінові кислоти формують більшість органічних колоїдів. Біообростання або прикріплення та розмноження мікроорганізмів на поверхні мембрани є ще однією проблемою.Проведені нами дослідження із очищення мембран за допомогою розчинів оцтової та яблучної кислот показали, що біологічну плівку, якою обростає мембрана, ці речовини розчиняють, але очистити пори і структуру мембрани від усіх забруднювачів харчові кислоти не в змозі. Тому варто шукати більш ефективні сполуки для регенерації мембран.

Використання водно-балансового моделювання водного стоку дозволило встановити, що з 2041 року можливе припинення місцевого поверхневого стоку в маловодні роки в Херсонській, Одеській, Миколаївській, Дніпропетровській та Запорізькій областях. Встановлено, що поверхневі та підземні водойми і питна вода в Одеській області, яка є однією із найбільш кризових у контексті водопостачання, слід розглядати як джерела перманентного епідеміологічного ризику. Констатовано  вкрай негативну тенденцію до припинення наукових досліджень взаємозв’язку біологічної контамінації всіх водних об’єктів  і захворюваністю населення.  Основними адаптаційними заходами до змін клімату для водного господарства південних областей (Одеської, Миколаївської, Херсонської, Запорізької) слід вважати раціональне використання наявних водних ресурсів та їхній захист від забруднення.

Movimento Escola sem Partido: anti-iluminismo, heteronomia, exclusão
Authors: Lourenço Nubia Almeida , Vaz Alexandre Fernandez
Published: May 2024

Os últimos anos viram emergir no cenário brasileiro o Movimento Escola Sem Partido (ESP), conjunto de convicções e práticas que pressupõe haver em instituições de ensino brasileiras um tipo de catequese político-ideológica – por eles denominada “doutrinação marxista” –, assim como a disseminação do que chamam “ideologia de gênero”. O artigo propõe analisar aspectos do ESP em seu movimento de disputa pela escola e, de maneira mais ampla, por um projeto de sociedade, observando-o como expressão de um processo mais longo, de construção do autoritarismo no Brasil e do avanço de uma agenda contrarrevolucionária. Para tanto, os principais documentos analisados são aqueles emitidos pelo próprio Movimento, atendo-se às categorias pelas quais se organizam suas propostas – tais como os conceitos de liberdade, formação, ciência, política – e às ideias e julgamentos lançados contra o que se supõe serem os perigos de uma educação esquerdista, a saber: a implementação de uma nova escala de valores contrária ao capitalismo liberal e à moralidade vista como cristã. Concluímos apontando como esses supostos perigos representam, para o ESP, a possibilidade de reprimir, na escola, a sexualidade e o pensamento, e de opor-se aos esforços educacionais que têm procurado gerar uma educação secular comprometida com a democratização da educação.

When carrying out research and technological processes in modern science and technology, the suppression or reduction of vibrations is often required for better operation of sensitive equipment and precision instruments. This paper presents a study on the damping of vibrations of a beam caused by the action of a dynamic load. The motion of an isotropic elastic beam is described using the model of S. P. Timoshenko. The beam has hinged supports at the edges. Damping moments located and acting at the anchoring points of the beam are used to damp the vibrations. As the beam moves in the hinges, a frictional moment with linear viscous damping occurs, which is proportional to the damping coefficient and the angular velocity of the beam in the hinge. In order to estimate the vibration damping, the solution of the direct problem of modeling the motion of the Timoshenko beam at zero ini- tial conditions is considered. The beam motion is modeled by a system of differential equations according to the model of S. P. Timoshenko. The re- quired functions are set in the form of Fourier series. Laplace integral transformation is used. The peculiarity of solution of a direct problem is that at this stage the friction moments in joints are unknown and are defined by solving corresponding inverse problem using Volterra integral equation the- ory. An analytical and numerical solution of the practical problem is obtained. Numerical results have been obtained in the form of graphs of beam point displacements and friction moments for different damping coefficients. A comparative evaluation of vibration reduction for different damping parameters has been carried out. The research results compare well with the results obtained by other authors.

The management of industrial enterprises in modern trends is multifaceted, among which the use of intellectual property plays an important role, which, in turn, is a means of increasing competitiveness, efficiency and profitability. The purpose of the article is to analyze the factors of changes in the features and types of intellectual property objects in modern management trends of industrial enterprises. The article analyzes the legislative regulation regulating the protection of intellectual property in Ukraine. Objects of intellectual property are identified, including: patent, copyright, trademark and privacy protection. Factors influencing changes in the characteristics of intellectual property objects are substantiated, among which technological changes, economic and market factors, changes in patent legislation, establishment of international standards, and socio-cultural aspects should be highlighted. It is proven that the mentioned factors make up a complex network of factors that influence each other and determine the dynamics of changes in the field of intellectual property in the modern management of industrial enterprises. It was determined that digital transformation has an impact on intellectual property objects. Such means of digital transformation as the Internet of Things, artificial intelligence, blockchain technology, virtual reality and augmented reality were analyzed. An integrated model of intellectual property management at an industrial enterprise is proposed, which involves a comprehensive approach to four aspects - innovation management, protection of intellectual property rights, strategic partnership and licensing, development of internal culture and education of the enterprise's personnel. The specified model will contribute to the sustainable development of the industrial enterprise and increase the level of its competitiveness in the market.

Published: May 2024

Case:

A 19-year-old woman sustained an open ankle fracture with complete destruction of the left medial malleolus and significant soft-tissue loss. After temporizing external fixation and coverage with a rotational posterior tibial artery perforator flap, the medial malleolus was reconstructed with an autologous iliac crest bone graft and direct repair of the deltoid ligament. The patient achieved excellent improvement in functional outcomes at 21 months with adequate restoration of ankle motion.

Conclusion:

This case shows reconstruction of the medial malleolus with autologous iliac crest bone graft after traumatic loss can be a viable treatment option for young patients.
Isolated Palsy of the Anterior Interosseous Nerve to Flexor Pollicis Longus, Magnetic Resonance Imaging and Clinical Correlation
Authors: Levidy Michael F. , Lindell Kenneth , Taylor Kenneth F.
Published: May 2024

Case:

Anterior interosseous nerve (AIN) palsy is an uncommon, though well-described, clinical entity. When isolated to the thumb, it can be confused with atraumatic rupture of the flexor pollicis longus (FPL) tendon. A 57-year-old man experienced atraumatic onset of difficulty flexing the distal interphalangeal thumb joint. Magnetic resonance imaging (MRI) demonstrated denervation edema of the FPL, suggesting atypical AIN palsy. Resolution of symptoms and MRI findings occurred concomitantly with nonoperative treatment.

Conclusion:

Atypical AIN palsy limited to the FPL is a rare clinical entity whose diagnosis can be supported with MRI. Here, we report a successful case of nonoperative management.

Published: May 2024

Cases:

Two competitive athletes with isolated comminuted trapezium fractures, sustained during American football and rugby, presented with pain and swelling of the first metacarpal base. Computed tomography confirmed isolated comminuted trapezium fractures. Arthroscopic reduction of displacement with screw fixation below the articular surface was performed through a small incision. Both patients returned to their preinjury sports levels within 2 months postoperatively.

Conclusion:

Arthroscopic treatment of isolated comminuted trapezium fractures achieved accurate reduction of articular surface displacement and preserved trapeziometacarpal joint stability with minimal soft-tissue invasion. This facilitated an early return to contact sports for the affected athletes.
Valoración de la gestión pública de la cultura: análisis en tres llamadas
Authors: Forero Medina Guillermo Alfonso
Published: May 2024

El presente artículo surge de la necesidad de implementar metodologías de valoración para la gestión pública de la cultura, junto con la ejecución de estrategias de articulación territorial entre los diferentes niveles de gobierno subnacionales. Para tal fin, cuenta con una estructura basada en una analogía sobre las tres llamadas de alistamiento para los espectáculos de las artes escénicas, que inicia con una aproximación conceptual sobre la relación entre los derechos culturales, las políticas culturales, la gobernanza cultural y la gestión pública, para luego hacer el análisis sistémico de una metodología de valoración de este tipo en Colombia, con el propósito de demostrar los impactos conducentes al mejoramiento de las capacidades de los gobiernos locales. Se concluye que los principios constitucionales de descentralización, participación y autonomía posibilitan el desarrollo de iniciativas gubernamentales para garantizar el libre ejercicio de los derechos culturales en los territorios.
“POP/STARS”

Published: May 2024

In 2018, American developer Riot Games introduced their new musical venture – K-pop virtual band K/DA – through a live augmented reality performance opening the League of Legends World Championship Finals. The band’s first single – POP/STARS – quickly became a hit even outside of gaming circles, leading the developers to stage a follow-up in 2020, when the band released a full EP titled ALL OUT. This article examines the evolution of the virtual band and its members as virtual characters, personas, and performers, at the intersection of discourses surrounding popular music, videogames, and hallyu.
"Thank You for Sharing this Fantastic Performance"
Authors: Jost Christofer
Published: May 2024

YouTube is one of the most important music media in the world today. Musical practice is reflected there in a variety of forms, from sound recordings to music videos to tutorials. The media environment that YouTube creates as a platform inscribes itself – to some degree – in the actions of those who use it. This is also the case with the YouTube drummer phenomenon, which this article examines in more detail in terms of the interplay between persona construction, music-making, media presentation, and transmedia content concatenation. The thesis is pursued that the practice of YouTube drummers creates a singular interference space of conventions, modes of action, and social roles, which in some places has novelty value with regard to music-related persona constructions and their implementation in platform-based audiovisual media, and which transcends media boundaries. The specificity of the persona construction essentially results from the mediating position of the drum-playing actors: they are not only performers who, like social media influencers, push into the light of publicity, but at the same time musical experts and instructors, quasi-curatorial music communicators who select, prepare, and present music of the past, and intermediaries of the corporeality of popular music. The analyses presented are based on exploratory investigations of the YouTube drummer field itself and a case study.

Autophagy is an intracellular, self-degradative process that serves the cell energy sources balance and tissue homeostasis, and is critical in multiple myeloma (MM) pathogenesis, however, the prognostic role of autophagy-related genes (ARGs) in MM remains undefined. In the present study, ARGs were selected from Gene Expression Omnibus datasets containing 1038 samples from patients with MM. Furthermore, an autophagy risk score (ARS) model was developed using Cox regression analysis. Patients with MM could be stratified into high- and low-risk groups with distinct clinical outcomes by ARS. Moreover, we established a nomogram, including the independent prognostic factor ARS and the International Staging System, which can improve the prognostic performance of MM. Gene Ontology analysis revealed that most of pathways enriched for ARGs were related to autophagy and metabolism. Furthermore, the critical role of ARNT-mediated autophagy in MM cell proliferation and drug resistance were validated using in vivo and in vitro strategies. Mechanistically, ARNT expresses in various immune cells in the bone marrow microenvironment, forming a positive feedback loop with hypoxia. Moreover, ARNT exacerbates autophagy through activating AKT signaling pathway. In conclusion, this study constructed an ARG-based prognostic model to predict the prognosis of patients with MM and revealed that targeting specific autophagy genes may provide potential insights relevant to MM treatment.

Introduction The high comorbidity of mental health conditions in people with epilepsy (PWE) is associated with poor quality of life and disability. Understanding the lived experience of mental health and illness in people with epilepsy has been little investigated in Africa and yet is essential to inform person-centred care. The aim of this study was to explore the experiences of mental ill-health in the contexts of the lives of PWE in rural Ethiopia.
Methods A phenomenological approach was employed, using in-depth individual interviews with PWE. Participants were selected purposely based on their mental distress score measured using a culturally validated scale (the Self-Reporting Questionnaire), their gender, and place of residence. The setting was the Gurage Zone in south-central Ethiopia where efforts had been made to expand access to mental health and epilepsy care through integration in primary health care in the Programme for Improving Mental Health carE (PRIME). Thematic analysis was used, supported by Open Code software.
Findings Twenty-two PWE were interviewed (8 women, 14 men). The following themes were identified: expression of ill-health; the essence of emotions; the emotional burden of epilepsy and aspirations and mitigating impacts. Participants reported multiple bodily (e.g. fatigue) and emotional (e.g. irritability, sadness) experiences which were tied up with their experience of epilepsy and not separable into physical vs. mental health. Occupation and social life difficulties were interconnected with emotional and bodily sickness. Emotions were considered inherently concerning, with emotional imbalance spoken of as a cause or trigger for seizures. These emotional burdens resulted in difficulties fulfilling occupational and social life obligations, in turn exacerbating the epilepsy-related stigma experienced from others. Participants sought to mitigate these inter-connected psychosocial impacts through finding spiritual meaning in, or acceptance of, their experiences, drawing on family care and, for some, emotional support from health professionals
Conclusions People living with epilepsy in this rural Ethiopian setting experience various emotional, financial, occupational and interpersonal problems which are crucially interwoven with one another and with the experience of epilepsy. A people-centred approach to supporting recovery of PWE requires consideration of mental health alongside physical health, as well as interventions outside the health system to address poverty and stigma.
