Extraction of Rare Earth Elements from Phalaborwa phosphogypsum
Authors: Wildenboer R.A. , Sandenbergh R.F.
Published: November 2024

Rare earth elements (REE) are present at concentrations of approximately 0.36 % in phosphogypsum stacks located in Phalaborwa, South Africa. The REE are present in the phosphogypsum in solid solution in the gypsum and as fluorine and aluminium rich precipitates. Recovery of the REE offers opportunities for valorization and reducing the environmental impact of the phosphogypsum waste. This paper presents the results of investigations into the leaching behaviour of rare earth elements and other impurities from phosphogypsum using aqueous sulfuric acid. The effects of acid concentration, temperature, residence time, and the influence of impurities were evaluated for their impact on the solubility of rare earth elements in a sulfate medium. It was found that a significant fraction of the REE can be leached from the phosphogypsum in a range of conditions much less severe than traditional hard rock rare earth processing conditions. The REE were leached at a sulfuric acid concentration of 110 g/l, temperature of 30°C - 40°C and a residence time of approximately 8 hours.
Development and verification of the least-squares collocation method with seventh degree polynomials for the biharmonic equation
Authors:   Khristianovich Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences, Bryndin Luka S.
Published: November 2024

A new version of the least-squares collocation method (C3 -LSCM7) with seventh degree polynomials is proposed and implemented. The method has continuity up to the third derivatives of the piecewise polynomial solution in the sense of least squares. This is achieved by using the values of the solution and its derivatives at the vertices of the grid cells as unknown terms. The C3 -LSCM7 is fundamentally different from previous versions of the LSCM in the absence of matching conditions. They explicitly require continuity of the solution and its derivatives at several points on the boundaries between neighboring cells. To solve the problem in a domain with a curved boundary a grid is constructed with rectangular cells. The solution of small irregular cells is continued from neighboring independent ones. Verification of the C3 -LSCM7 is carried out by solving two-dimensional boundary value problems for a biharmonic equation in a square and in domain with the curvilinear boundary. The condition numbers of a global matrix and transition matrices from values at nodes to coefficients of polynomial expansion are studied. The advantages of the C3 -LSCM7 over previous versions of the LSCM are shown.
The effect of initial stresses on sound wave propagation in hypoelastic anisotropic materials
Authors:   Tula State University, Sokolova Marina Yu. , Markin Aleksey A. ,   Tula State University
Published: November 2024

A linearized equation for the propagation of acoustic waves in bodies with preliminary finite deformations and initial stresses is obtained for hypoelastic materials. The equation is written in terms of the velocity field, which leads to perturbations of the initial configuration of the medium. The formula for a symmetric acoustic tensor is written for plane monochromatic waves. It is shown that if a plane wave propagates along one of the anisotropy axes in cubic material, then the normal stresses in the plane of the wave front affect the phase propagation velocities of both longitudinal and transverse waves. The normal stresses acting perpendicular to the wave normal vector affect only the magnitude of the phase velocity of the transverse wave polarized along the stress direction. The shear stresses acting in the plane of the wave front have an effect on the propagation velocities of quasi-longitudinal and quasi-transverse waves. The shear stresses acting in the plane perpendicular to the wave front affect only the phase velocities of transverse waves. Analysis of the effect of initial stress on wave propagation in an isotropic material allowed revealing the occurrence of anisotropy in the acoustic properties of the medium and to describe shear wave splitting.

The article discusses the urgent problem of modeling the processes of inventive activities under the influence of many factors of uncertainty characteristic for the interaction and mutual dependence of innovation ecosystems subjects. The indicated models of the processes of inventive activities, the interdependence and interaction of the subjects of innovative ecosystems, firstly, are necessary for the understanding and adequate perception of the processes occurring in the ecosystems themselves. Secondly, such models are needed to develop and create intellectual systems for supporting solutions in the field of management and financing of companies and organizations included in such ecosystems, as well as in the field of rights to IP, and for solving other problems. A young innovative company – startup – is considered as the central link of the ecosystem, whose intellectual activity result is ideas formalized in the form of applications for inventions sent to the patent office. Streams of random events of filing patent applications by a startup and receiving decisions from the patent office are considered within the framework of classical probability theory. The ecosystem model, built as a Bayesian belief network, makes it possible to take into account not only the events of patent signals on the emergence of new technologies (inventions) at a startup, but also the cause-and-effect relationships between all subjects of the innovation ecosystem, including a startup, an independent expert technology broker, an institutional investor (venture fund), and the patent office. As a result of training the constructed model and subsequent analytical and diagnostic conclusions, the venture fund is able to extract new knowledge and reasonably reduce uncertainty when making decisions about financing a startup, taking into account the current state of its patent portfolio. The Bayesian model of an innovative ecosystem has been proposed and implemented, which, in fact, is a prototype of an intellectual system for supporting the solutions of an institutional investor (venture fund) on financing (continuation of financing) of a startup. The model takes into account not only the presence of the so-called market patent signal about the emergence of a new technology (invention), but also the judgments of experts of different levels about the quality and novelty of this technology. The ability to quickly retrain the model, for example, in accordance with new knowledge obtained by the investor during the analysis, allows the investors decision support system to be adapted to any quantitative probabilistic assessments of experts.

We are following Kondratiev, Shumpeter and Perez who argued that radical innovations depend on financial capital. The aim of the article is to explore non-speculative players in the financing process of the AI Revolution and determine the country specifics of Russia and China in this process. Our main approach to reveal and study non-speculative players in the global financing process of the AI revolution is to differentiate the public sector of the economy, on the one hand, and for-profit and non-profit organizations, on the other hand. The key findings of our empirical study with a practical focus are that academies of sciences, state universities and non-profit organisations are both beneficiaries and investors of technological development in general and the AI revolution in particular. We put forward a thesis about the role of speculative capital in the technological development in the duration reduction of technological waves from 60 years (1st wave) to 25 years (6th wave) by the MIT approach. The originality of the article is in its focus on solving of AI inequality problem at state universities and nonprofit organizations as beneficiaries, investors and social lift, especially for people in Russia and China. We believe that a new Black Monday on August 5, 2024, is the beginning of the AI bubble.

The efficiency of modern enterprises directly depends on the level of developed and implemented innovations. In modern conditions, in order to ensure the sustainability of the economic development of the Russian Federation, the issues of updating outdated low-tech industries based on digital technologies are of particular relevance, which forms the basis of the Industry 4.0 concept. The leading role in the implementation of the processes of industry’s innovative development is played by the state. It is the state authorities that create the legislative and institutional framework for the formation of these processes and effective economic mechanisms for their practical implementation. The main scientific results of the study made it possible to solve an important scientific and applied problem of developing and substantiating theoretical and methodological foundations and scientific and practical recommendations for investment support of innovative industrial development in the Russian Federation. Based on the analysis of the economic literature, we come to the conclusion that at present a relevant direction is the development of a technologically evolutionary approach to the study of industrial development in terms of identifying the relationship and interdependence of its stages, caused by innovative scientific, technical and technological factors, as well as economic, socio-historical events. A generalization of trends in evolution revealed factors of direct influence on the state of industrial development, the formation and strategic direction of which will ensure the achievement of a higher technical and technological level.

USDA LTAR Common Experiment measurement: Snow v1

Published: November 2024

Snow plays an important role in the hydrological and energy cycles. In agroecosystems, snow may be a beneficial source of plant-available water, a harmful source of flooding, a source of irrigation water supply (i.e., mountain snowpack filling reservoirs), and a determinant of seasonal timing, such as the onset of the planting or growing seasons. Key snow metrics include snowfall (precipitation amount), snow water equivalent (SWE), and snow depth. Depending on the application, we may be interested in the snowfall rate of a particular storm event (e.g., 60 mm of water equivalent fell overnight, and the weight damaged crop trees) or the total amount over a season (e.g., 400 mm of total winter snowfall will provide moist spring soil). Snowfall measurement is in some ways similar to rainfall measurement, to quantify the rate (e.g., per hour or day) of precipitation through a horizontal plane (opening of a precipitation gauge). However, it is usually necessary to melt the snow within the gauge. Snowfall measurement is also susceptible to the effects of wind, which can accelerate snow laterally past the gauge opening, resulting in “undercatch.” Snow depth is the most readily observable property, requiring only a graduated stake or other simple measurement devices. However, depth does not directly convey the water content. Snow depth may increase because of new snowfall or deposition by wind. Snow depth at a point may decrease because of settling over time (often within hours), compaction by overlying snow, melting, sublimation (evaporation of ice crystals), or scouring by wind. In addition to weather, these processes are regulated by local physiographic factors, including topography (slope and aspect with regard to sun and wind), and by trees, crops, or other vegetation. Since these factors may result in high variability of snow depth over short distances, snow depth measurements in many locations at a given time point are often desirable to assess conditions in a watershed, field, or plot. Snow water equivalent is usually considered the most important metric of snowpack since it represents the water available upon melting. SWE is the product of depth and density. Density is affected by similar factors as snow depth as well as age. Freshly fallen snow often has low density that increases with time on the ground as snow crystals lose their fine edges through friction, compaction, and partial melting. This protocol describes the measurement of: ●Snow depth ●Snow water equivalent ●Snowfall ●Remote sensing and other long-term/large-scale snow products
Cyclic Heat Induced Epitope Retrieval (CHIER) v1
Authors: Dieriks Victor
Published: November 2024

Immunolabeling is a cornerstone technique in molecular biology and pathology, providing critical insights into protein localisation and function within biological tissues. However, one of the persistent challenges in immunolabeling is the effective unmasking of epitopes, which are often concealed in formalin-fixed, paraffin-embedded (FFPE) tissue samples. While effective to an extent, traditional antigen retrieval methods have limitations in consistency, epitope preservation, and overall labelling efficiency. We introduce a novel antigen retrieval protocol, Cyclic Heat Induced Epitope Retrieval (CHIER) to address these issues. The development of CHIER is particularly crucial for studies involving proteins that are notoriously difficult to label due to dense cross-linking or subtle epitope masking. By improving the efficiency of antigen retrieval, CHIER enhances the sensitivity and specificity of antibody binding in immunohistochemical (IHC) and immunofluorescence (IF) assays. This results in more robust staining and can facilitate the detection of densely aggregated proteins, which is essential for accurate protein localisation and quantification studies. Significantly, CHIER demonstrated a remarkable ability to increase the detection of the protein of interest (SWI/SNF related, matrix-associated, actin-dependent regulator of chromatin subfamily c member 2, SMARCC2), with results showing a 3x increase in detection compared to traditional methods. This enhancement in detection efficiency makes CHIER a valuable tool for researchers in diverse fields, including neurobiology, cancer research, and tissue pathology, where precise antigen detection is paramount. Introducing CHIER into these fields is expected to significantly advance our understanding of complex protein dynamics and interactions in various biological and disease contexts.

Are alarm symptoms valuable in predicting upper gastrointestinal malignancy?
Authors: Fidan Sami
Published: November 2024

Background and Aims: The diagnostic utility of alarm symptoms in predicting upper gastrointestinal cancers is uncertain. In our study, we aimed to investigate the predictive value of alarm symptoms in the diagnosis of upper gastrointestinal cancers. Materials and Methods: This prospective observational study included patients with at least one or more alarm symptoms of upper gastrointestinal cancers who underwent esophagogastroduodenoscopy. Patients under 18 years of age and over 80 years of age were excluded. Patients were divided into two groups as under and over 45 years of age. Demographic characteristics, presenting complaints, alarm symptoms, endoscopy and pathology results were evaluated prospectively. Results: A total of 325 patients were included in the study, 62.5% of whom were female, with a mean age of 50.8 ± 15.8 years. The most common alarm symptoms were new-onset dyspepsia over 45 years of age (48.6%), weight loss (34.8%) and iron deficiency anemia (31.1%), respectively. In our study, malignancy was diagnosed in 8 patients (2.5%), 6 of whom were male, and all of whom were over 45 years of age. The alarm symptoms with the highest sensitivity were weight loss (75%) and iron deficiency anemia (50%), while the alarm symptoms with the highest specificity were palpable abdominal/epigastric mass or abnormal lymphadenopathy (96.5%) and upper gastrointestinal bleeding (96.2%). Conclusion: The sensitivity and specificity of alarming features in predicting upper gastrointestinal cancers is limited and other methods need to be developed to define the at-risk population.

The current trends in the development of electronic warfare in the world highlight the problem of qualitative improvement of electronic warfare samples. Qualitative improvement consists in ensuring high functional efficiency, cost-effectiveness and guaranteed safety of complex electronic warfare systems and is determined by a system of scientific, technological and organizational problems. The interrelation of these problems can be revealed during the analysis of the management system for the implementation of development programs, within which the creation of electronic warfare samples is carried out. The scale and complexity of the tasks of creating electronic warfare samples is concentrated in a technological process called the life cycle. An important stage of this cycle is testing, a unique type of research that allows us to assess the quality of electronic warfare samples in conditions as close as possible to the real conditions of their operation.

Solving the management task of optimizing the process of testing electronic warfare equipment under given resource, primarily time and price constraints, in order to improve the quality of the tested samples and the level of readiness of the standard equipment used.

In their introductory essay, Maurizio Calbi and Stephen O'Neill explore the interrelations between social media and Shakespeare(s), providing a theoretical consideration of both categories that ultimately moves toward an argument for their rhizomatic intersections. Shakespeare increasingly "becomes" through social media (in a Deleuzian sense), and indeed, forms of social media are rearticulated through Shakespeare. The essay also guides the reader through this special issue in which the contributors variously map, define, scrutinize, and challenge social media, Shakespeare and their uncanny convergences.

Five Kings: Adapting Welles Adapting Shakespeare in Québec
Authors: Drouin Jennifer , Ritchie Fiona
Published: November 2024

Five Kings: L'Histoire de notre chute is an ambitious adaptation in French of Shakespeare's two tetralogies of history plays. As the title suggests, the creators have been influenced by Orson Welles's adaptation of the same name, and in the program notes they express their desire to pick up where Welles left off. We can therefore read Five Kings as an attempt by these four adapters to stake their claim as artistic professionals and redoubtable Shakespeareans. The Five Kings creative team is to be congratulated for managing to stage the entire sequence of Shakespeare's eight history plays in the same five-hour time frame in which Welles staged the second tetralogy. Besting Welles is no mean feat.
The Art of Curation: Searching for Global Shakespeares in the Digital Archives
Authors: Desmet Christy
Published: November 2024

Scholarly sites devoted to global Shakespeare are strictly curated, usually by one or two persons with impeccable credentials. By contrast, YouTube, as the quintessential crowd-sourced and user-structured video archive, depends on individual contributions for its raw material, and on a combination of imitation, dialogue, and a complicated computer algorithm to establish relationships among the videos. This essay considers how differences in curation and context between these two kinds of archives might affect the understanding and reception of global Shakespeares. The paper compares cognitive and intellectual strategies brought to bear in the YouTube environment with the more structured methods of curating and providing intellectual paratexts in three sample scholarly archives: Bardbox, CASP (Canadian Adaptations of Shakespeare Project; and the Global Shakespeares Video & Performance Archive (MIT).
Staging Shakespeare in Social Games: Towards a Theory of Theatrical Game Design Authors
Authors: Roberts-Smith Jennifer , DeSouza-Coelho Shawn , Malone Toby
Published: November 2024

This essay discusses the theoretical implications of a recent experiment with game-based social media to increase Shakespeare literacy in eleven to fifteen-year-olds. In collaboration with the Stratford Festival, we aimed to make the gameplay of our pilot, Staging Shakespeare, and the social space it generated, experientially theatrical in some way. While the pilot itself was not, in our view, successful, the design process helped us articulate a theory of theatricality grounded in the ontological complexity of theatrical things and the ontogenetic conditions of theatrical environments. Our conclusion is that literal simulations of Shakespeare's plays or of Shakespearean theater production may not be the richest way to teach Shakespeare through social games. Instead, we may need a design theory grounded in the adaptation of theatrical principles to electronic media, and perhaps a new aesthetic and even a rhetoric of gameplay only associatively related to Shakespeare.
"We'll measure them a measure, and be gone": Renaissance Dance Practices and Shakespeare's Romeo and Juliet Authors
Authors: Winerock Emily
Published: November 2024

Dance is an oft-overlooked, yet frequent feature in Shakespeare's plays. The playwright utilizes dance scenes, not only to convey general festivity and celebration, but also to advance plots, to display character traits such as grace and nobility (or their absence), and to highlight the development of romantic relationships. While there are no surviving records detailing the original staging of these dance scenes, there are extant dancing manuals from the period that explain how to do many of the dances that Shakespeare mentions. Moreover, references in a plethora of early modern literary, pictorial, and archival sources offer evidence of how these dances were understood and interpreted by dancers and spectators. Using Romeo and Juliet as a case study, this paper demonstrates how one can bring together these diverse sources, supplemented by the insights gained from the "experiential learning" of staging these dances for live audiences, in order to choreograph historically-informed dances, regardless of whether the production is set in the Elizabethan period or the present day. Finally, the paper argues that a better understanding of Shakespeare's dance scenes enables us to gain a better understanding of his plays' central concerns and questions overall.

A blend of various materials with nano-scale dimensions is called a nanocomposite. Combining the qualities of various materials to create a unique nanomaterial with improved and increased chemical and physical capabilities is the goal of creating nanocomposites. The characteristics of nanocomposites and raw materials are very different. On comparing nanocomposites to standard composite materials, a big surface area and a remarkable surface-to-volume ratio are seen. Environmental professionals have taken an interest in these composite materials, particularly in relation to their ability to remove pesticides from various samples. This is mostly due to the many special qualities that the nanomaterials which help with pesticide remediation offer. The necessity of composite materials above conventional materials is demonstrated by this study. Composite parts are produced in several industries using various moulding techniques. The main benefits of composites are their relative stiffness, strength and lightweight. The physical characteristics, material qualities, design, tooling, inspection and repair of composites are its fundamental ideas. Strong, lightweight materials are crucial for military vehicles like rockets, helicopters and aeroplanes. In terms of mechanical qualities, the metallic components that had been utilised until that point undoubtedly performed the job, but their large weight was prohibitive. The polymer industry was expanding rapidly and aimed to broaden the market for plastics to include a wider range of applications. A potential remedy was provided by the introduction of novel, lightweight polymers from research and development facilities.

Published: November 2024

The value orientation of youth is essential to national development in the Fourth Industrial Revolution era. The theoretical foundations and real-world effects of value orientation for young Vietnamese people are investigated in this research. Vietnamese Communist Party has always understood the importance of young issues in determining the course of the country. Traditional value systems have to adjust to the new problems brought about by fast technical developments and changing socio-cultural dynamics. In order to guide Vietnamese youth's ideas, ideals, and behaviors, new methods are needed, as this study investigates the theoretical frameworks and empirical evidence around their value orientations. The study gives a thorough evaluation of the existing value environment and suggests ways to promote a balanced value system that combines national and universal values by addressing the ideological trends of presentism and pragmatism.

This paper represents performance of air-hydrogen free-breathing Fuel Cell (FC) in limited volume conditions. Research work was carried out with thin two-cell stacks related to use in prototype of particular power source system, which includes aluminium-water microgenerator of hydrogen. In small current densities field (<200 mA/cm2) it was established, that after FC had been confined within the small volume, characteristics of FC became better than in non-limited-volume conditions due to self humidification. While experiments the relationship between characteristics of FC and speeds of cathode gap perflation by air was studied, and the existence of optimal speed of perflation was defined. Optimal speed of perflation provides for both required amount of air in the gap, and high air humidity in the pericathodic space. In medium current densities field (200–500 mA/cm2) optimal speed of perflation exists too. In high humidity conditions (RH=70%) in non-limited-volume the level of 250 mW/cm2 at single FC voltage of 0.5 V was achieved in long-term experiment.

A luta no território tradicionalmente ocupados por famílias camponesas agroextrativistas sempre foi pautada por disputas por madeireiros, fazendeiros, grileiros, que concorrem opostamente aos recursos da terra e da natureza na Amazônia. No Pará, apesar criação de assentamentos coletivos agroextrativistas, há uma forte concentração fundiária, que se agrava quando incorpora elementos que ampliam as querelas da terra com os recursos naturais das florestas. Este artigo tem como objetivo analisar os principais desafios das famílias da Gleba Joana Peres, desde o processo de regularização fundiária e na delimitação do seu território. As análises se debruçaram sobre o estudo de caso na criação dos Projetos Estaduais de Assentamentos Agroextrativistas (PEAEX) Dorothy Stang e PEAEX Joana Peres, busca-se averiguar o histórico da área, além de realizar um levantamento sobre a situação socioeconômica, de produção, renda e organização social das famílias com a finalidade de identificar suas trajetórias e perspectivas. Durante a pesquise identificou-se grande número de organizações sociais, que construíram ações políticas coletivas junto aos agentes públicos, rede de articulação dos movimentos e com as famílias camponesas. A organização local das famílias permitiu a construção dos repertórios para a conquista da regularização fundiária, o que muito significativo. Entretanto, ainda há uma fragilidade no engajamento das famílias que se reflete na baixa adesão as entidades sindicais e do movimento social, o que fragiliza o processo formativo político-pedagógico das ações sociais coletivas, no âmbito da disputa dos territórios, dos recursos naturais, manutenção do modo de vida tradicional.

Este artigo científico busca analisar como ocorre a colonialidade do saber pela Modernidade Ocidental e, nesse contexto, como se dá a resistência das comunidades quilombolas brasileiras em defesa dos seus conhecimentos e identidades culturais nas lutas pela preservação, reconhecimento, justiça e equidade epistêmica. Exploramos alguns aspectos do quadro teórico Epistemologias do Sul como possibilidades de avanço para a superação da colonialidade dos conhecimentos quilombolas. Para desenvolver o que é proposto, este trabalho pautou-se em uma abordagem qualitativa, baseada em referenciais bibliográficos, com a análise das ideias de vários autores decoloniais. A partir do percurso aqui realizado podemos concluir que a hegemonia moderna eurocêntrica ocidental sobre o conhecimento e sua perspectiva restritiva da ciência, que marginaliza e invisibiliza os conhecimentos provenientes de outros povos e locais, são alguns dos aspectos mais devastadores da Modernidade Ocidental. Porém, as comunidades quilombolas estão em constante movimento de luta e defesa por suas culturas, tradições, saberes e territórios, buscando sempre formas de resistir e preservar suas ontologias e epistemologias. Ainda, as Epistemologias do Sul, ao darem voz aos diferentes atores sociais, ao valorizarem os diversos saberes e ao questionarem as hierarquias de conhecimento presentes nas instituições acadêmicas, oferecem ferramentas importantes para promover a decolonialidade dos conhecimentos quilombolas. Palavras-chave: Colonialidade do saber. Decolonialidade. Saberes quilombolas. Resistência quilombola. Epistemologias do Sul.

Our study identified seven unique heterocyclic compounds: 2-(m Tolylthio) Chalcone, chitosan oligosaccharide, and 2-hydroxy chalcone. Six-chloropyridine, 4-naphthoquinone, Thiobenzimidazole, 2-thiobenzoxazole, 6-carboxylic acid ethyl ester, and Anthrimide are probable choices that may be found in a chemical database. Posaconazole and Isuvuconazole are reference compounds found in a literature study. The isuvuconazole-bound complex of Acanthamoeba castellanii CYP51 of PDBID 6UX0 is the focus of our investigation. Docking simulations were carried out to evaluate these drugs' binding affinity to the Acanthamoeba castellanii CYP51 complex, using Isuvuconazole as the reference compound. Vina Wizard and PyRX software were used to carry out the docking simulations. Anthrimide, the ligand, demonstrated a binding energy of -10.3 kcal/mol in our data, indicating great promise for treating antifungal diseases in the future. Auto dock further validated this value to be -10.2. Further in vivo testing will confirm the findings of this study.

A calm insanity of any kind was included in the original broad definition of melancholia along with the present idea of affective illnesses, which today views mood as the primary disturbance, the term depression first appeared in the nineteenth century. A very complicated mental illness, major depressive disorder (MDD) is commonly referred to as depression. It is marked by a depressed mood, diminished interests, and disinterest in routine tasks, feelings of loneliness, impaired cognitive function, and vegetative symptoms like disturbed sleep or appetite and a lack of desire. Research illustrating the frequency of depression in kids and teens reveals that a sizable portion of kids in both age groups experience symptoms of despair. According to the analysis, there are no differences between the adult and child depression constructs in terms of mental classifications, and a comprehensive understanding of depression. Considering the child's developmental stage and cognitive and linguistic abilities, children with MDD share many of the same key characteristics as adults and adolescents. Research on the general population is the only source of information on many significant issues regarding depression in young people. Teens suffering from mental illnesses are a vulnerable population that requires more care. It takes equilibrium between feelings, ideas, and behavior to maintain mental health. An important source of morbidity and death in children and adolescents is depression disorders, which are frequent and repeated illnesses. Adult psychopathology has been linked to early trauma in the form of physical or sexual abuse experienced as a kid. Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed as the initial treatment for depression in children and adolescents. Fluoxetine offers the strongest safety and effectiveness data when compared to other antidepressants, especially when used in teenagers who are 12 years of age or older. Adolescents' self-reports of attachment anxiety and avoidance can be effectively addressed through Interpersonal Psychotherapy for Adolescents (IPT-A). This therapy appears particularly beneficial for those exhibiting high levels of avoidant attachment. The study highlights that attachment anxiety and avoidance are modifiable during adolescence and can be viable treatment targets. IPT-A has proven effective in treating attachment-related issues, with reductions in attachment anxiety and avoidance correlating with decreases in depressive symptoms. This supports the use of IPT-A for depressed adolescents struggling with attachment security, especially those with an avoidant attachment style who tend to shy away from intimacy.

Recurrent, intense headaches that are accompanied by a number of other symptoms are the hallmark of the complicated neurological illness known as Migraine. This research focuses on finding a therapeutic relationship between Migraine and Music. Music therapy, a specialised field that employs music to address physical, emotional, cognitive, and social needs of individuals, has gained traction in diverse medical settings. We have taken in account several musical characteristics like duration of listening, category of music, effectiveness of music in improving the migraine associated pain, gender wise differences in music listening habits, and many more. Between August 31, 2023, and October 6, 2023, a Pan-India cross-sectional analysis was carried out across several medical colleges in India. A self-administered questionnaire was utilised to collect data using web-based links and statistical analysis was made using appropriate tools. All participants were 18 years old or older, moreover all of them were enrolled in MBBS colleges in India. A total of 384 students participated in the study (170 Females and 214 Males). With the help of Headache Screening Questionnaire (HSQ) 8.41% males and 13.52% females are suspected migraine patients. Furthermore, the type of music preferred by subjects and the duration of music listening was taken into account. Then, the Chi-squared value was obtained as 4.40649125 and with the help of the same, P-value was obtained to be 0.110449. The p-value < 0.05, indicating that the result is not statistically significant. While this study did not find a robust relationship between music and migraine pain relief, future research with more advanced tools and a larger sample size could potentially uncover a significant association. The current findings suggest that music may play a modest role in the therapeutic management of migraine pain. However, further exploration is warranted, as music therapy holds promise as a fascinating complementary approach that could aid in migraine treatment with minimal or no medication. Delving deeper into the psychological and neurological mechanisms underlying music's perceived efficacy in migraine management may elucidate its true therapeutic potential.
