Biochemical Evaluation and Stability Assessment of Eye Drops Manufactured at Mengo Hospital: A Quality Control Study
Authors: Andrew R. Arinda
Published: September 2024

This comprehensive study undertook a thorough evaluation of the biochemical composition and stability of eye drops manufactured at Mengo Hospital. A range of analytical tests were conducted to assess the eye drops' pH, osmolarity, viscosity, protein content, and susceptibility to microbial contamination. Additionally, stability testing was performed under various storage conditions to simulate real-world scenarios. The results of the study revealed that the eye drops manufactured at Mengo Hospital largely conformed to regulatory standards for pH and osmolarity. However, significant variations were observed in viscosity and protein content, indicating inconsistencies in the manufacturing process. Furthermore, stability testing under accelerated conditions demonstrated degradation of the eye drops, highlighting concerns regarding their shelf life and potency. Notably, microbial contamination was detected in some samples, raising concerns about the risk of eye infections and the need for improved sterilization protocols. A comparative analysis with commercial eye drops revealed similarities in biochemical composition but distinct differences in stability profiles. This suggests that while the Mengo Hospital eye drops may possess similar characteristics to commercial products, their stability and longevity may be compromised. The findings of this study have significant implications for quality improvement initiatives at Mengo Hospital. Recommendations include optimizing the manufacturing process to minimize variations in viscosity and protein content, implementing enhanced sterilization protocols to prevent microbial contamination, and conducting regular stability testing to ensure the eye drops' potency and shelf life. By addressing these areas, Mengo Hospital can enhance the quality and safety of its eye drops, ultimately benefiting patients and maintaining trust in its products.

Published: September 2024

In the solar energy sector, the task of monitoring and maintaining large photovoltaic (PV) system portfolios is essential for ensuring optimal performance and reliability. Prominent solar energy companies face challenges with their current fault detection methods, which are inefficient and resource- intensive. This paper addresses the critical need for improved fault detection in solar PV systems to maximize uptime and minimize maintenance costs. We employed advanced data preprocessing and augmentation techniques using Roboflow and developed a YOLOv8 segmentation model in Google Colab with GPU. This model was then deployed using Streamlit, providing a robust solution for identifying faulty solar modules. The proposed approach significantly enhances fault detection accuracy, achieving a minimum accuracy rate of 85%, thus ensuring reliable operation of the PV systems. Additionally, the implementation of this model contributes to a 15% reduction in system downtime and a 10% reduction in maintenance costs. By leveraging advanced machine learning techniques, our solution transforms the maintenance process, making it more efficient and cost-effective. Consequently, this work not only improves the reliability and performance of solar PV systems but also supports the broader goal of sustainable energy through more efficient resource usage.
Mapping Poverty for Sustainable Development Using AI, A Review of Literature
Authors: Kimwomi George , Mgala Mvurya
Published: September 2024

Extreme poverty is among the challenges the United Nations seeks to eradicate by the year 2030 as outlined in its Sustainable Development Goals. However, governments and other stakeholders face challenges in accurately identifying poverty in households for evidence- based implementation of SDG programs. Current strategies are slow, inaccurate and costly to efficiently support efforts to identify poverty for sustainable development. Consequently, many strategies to map out poverty for intervention measures do not succeed which could be contributing to the global decline in the rate of reducing poverty. Artificial intelligence which has become widely available and has been used in many sectors, could be leveraged to improve poverty mapping for evidence-based interventions for sustainable development. Despite living in the era of AI, it has not been fully utilized in mapping poverty. This review seeks to explore the extent of research on the adoption of AI in mapping poverty so as to find the gap for further research. It aims to establish the extent of AI-based research on identification of poverty in respect to global distribution of research studies, methods, algorithms and sources of data which have been used in studies to identify poverty. The findings will help to identify gaps for research to help in designing evidence-based strategies for intervention measures. A systematic review was done for the period 2020 to 2024 using databases and snowballing hybrid search approach. A qualitative analysis was done on the extracted data to uncover new patterns and identify research gaps.
CUSTOMARY LAND GOVERNANCE AND CONFLICT RESOLUTION AMONG THE DEBNE AND WEIMA AFAR CLANS, NORTHEAST ETHIOPIA
Authors: Debsu Dejene
Published: September 2024

This study is based on three months of fieldwork among the Debne and Weima Afar clans in Amibara
woreda
(district), Afar National Regional State (ANRS), Ethiopia, which was conducted in three rounds in 2016, 2018 and 2022. The purpose of the study is to explore the customary organisational structure and the rules and regulations employed by the local communities in managing natural resources on their rangelands as well as in resolving conflicts. While the clan system provides the basis for the Afar social and political organisation, claims to land are made at subclan and lineage levels. The formal administration largely functions using the clan structure, as it has more legitimacy than the state itself. Given the infrastructural limitations and legitimacy deficits of the government in the region, this paper argues that the clan system continues to play a dominating role when it comes to social organisation, resource management and conflict resolution.

THE SHEPHERD COMMUNITY OF THE ALBANIAN ALPS: PERSPECTIVE ON THE IMPORTANCE OF PRESERVING TRANSHUMANCE PRACTICES
Authors: Wolff Martine
Published: September 2024

This study, part of a request for UNESCO to protect the practice of transhumance, provides a reflection carried out by shepherds in dialogue with pastoral agents who have accompanied them for several years. The dynamics of transhumance, a multi-millennial practice, links to a group of populations and a particular civilisation characterised by a historical, linguistic, cultural and social specificities. Transhumant pastoralism belongs to their cultural identity. Considering current governance systems, the problem exposed will be studied according to what constitutes the phenomenon of transhumance and its historical evolution. How are the shepherds situated in terms of resilience and resistance? What are their vulnerabilities and their capacities for adaptation? What is their conception of appropriate governance while respecting their traditional culture? This text intends to give some answers that they provided.

A Raster-oriented Method for Creating Eclipse Maps
Authors: Wright Ernie , Young C. Alex
Published: September 2024

Traditional total solar eclipse maps based on 19th-century calculation methods do not take full advantage of important refinements recently made possible by fast computers and high-resolution digital elevation models of both the Earth and the Moon. Ignoring the terrain of both bodies introduces errors on the order of kilometers in the ground track of the umbra and seconds in the duration and contact times of totality. While this has been understood to some degree for decades, it has not been visualized in maps until quite recently, revealing only in the last decade the surprising polygonal shape of the umbra. Beginning in December of 2016, we published maps and animations of the 2017 August 21 total solar eclipse created with a raster-oriented approach that relies on remote-sensing data sets and computer graphics techniques to produce more accurate maps and professional-quality animations. These were an important component of NASA’s public outreach for the 2017 eclipse.

Published: September 2024

Neutral atomic hydrogen and molecular gas in the host galaxies of radio active galactic nuclei can be traced using H i 21 cm and OH-1667 MHz absorption lines to understand the fueling and feedback processes. We present the results of an H i and OH absorption survey with the Five-hundred-meter Aperture Spherical radio Telescope toward 40 radio sources of low–intermediate radio luminosity (∼1023–1026 W Hz−1 at 1.4 GHz), red mid-infrared color (W2[4.6 μm]–W3[12 μm] > 2.5 mag), and redshift up to 0.35. From 13 sources with good data at H i observing frequencies, we report the detection of H i absorption toward eight sources, five of which are new detections, including four in the redshift range 0.25–0.35. Our detection rates are consistent with our previous results, with the dependence on the star formation history of the host galaxies reflected in the mid-infrared Wide-field Infrared Survey Explorer W2−W3 colors and the compactness of the radio sources. We find no significant dependence of the detection rates on radio luminosity or redshift. We also find that the H i column densities are anticorrelated with the low-frequency spectral indices (

A Targeted Search for Variable Gravitationally Lensed Quasars
Authors: Sheu William , Huang Xiaosheng , Cikota Aleksandar , Suzuki Nao , Palmese Antonella , Schlegel David J. , Storfer Christopher
Published: September 2024

We present a pipeline to identify photometric variability within strong gravitationally lensing candidates, in the Dark Energy Spectroscopic Instrument Legacy Imaging Surveys. In our first paper, we laid out our pipeline and presented seven new gravitationally lensed supernovae candidates in a retrospective search. In this companion paper, we apply a modified version of that pipeline to search for gravitationally lensed quasars. From a sample of 5807 strong lenses, we have identified 13 new gravitationally lensed quasar candidates (three of them quadruply lensed). We note that our methodology differs from most lensed quasar search algorithms that solely rely on the morphology, location, and color of the candidate systems. By also accounting for the temporal photometric variability of the posited lensed images in our search via difference imaging, we have discovered new lensed quasar candidates. While variability searches using difference imaging algorithms have been done in the past, they are typically performed over vast swathes of the sky, whereas we specifically target strong gravitationally lensed candidates. We also have applied our pipeline to 655 known gravitationally lensed quasar candidates from past lensed quasar searches, of which we identified 13 that display significant variability (one of them quadruply lensed). This pipeline demonstrates a promising search strategy to discover gravitationally lensed quasars in other existing and upcoming surveys.
A Kinetic-magnetohydrodynamic Model with Adaptive Mesh Refinement for Modeling Heliosphere Neutral-plasma Interaction
Authors: Chen Yuxi , Toth Gabor , Powell Erick , Arshad Talha , Bair Ethan , Kornbleuth Marc , Opher Merav
Published: September 2024

The charge exchange between the interstellar medium and the solar wind plasma is crucial for determining the structures of the heliosphere. Since both the neutral-ion and neutral–neutral collision mean free paths are either comparable to or larger than the size of the heliosphere, the neutral phase space distribution can deviate far away from the Maxwellian distribution. A kinetic description for the neutrals is crucial for accurately modeling the heliosphere. It is computationally challenging to run three-dimensional time-dependent kinetic simulations due to the large number of macroparticles. In this paper, we present the new highly efficient Solar Wind with Hydrogen Ion Exchange and Large-scale Dynamics-2 model with a kinetic model of neutrals and a magnetohydrodynamic model for the ions and electrons. To improve the simulation efficiency, we implement adaptive mesh refinement and particle splitting and merging algorithms for the neutral particles to reduce the particle number that is required for an accurate simulation. We present several tests to verify and demonstrate the capabilities of the model.
Observational Evidence of Particle Acceleration by Relativistic Magnetic Reconnection in Gamma-Ray Bursts
Authors: Peng Cheng-Feng , Lu Rui-Jing , Liang Wen-Qiang , Chen Zhe-geng
Published: September 2024

Gamma-ray bursts (GRBs) as the most energetic explosions in the modern universe have been studied for over half a century, but the physics of the particle acceleration and radiation responsible for their observed spectral behaviors are still not well understood. Based on the comprehensive analysis of the pulse properties in both bright GRB 160625B and GRB 160509A, for the first time, we identify evidence of particle acceleration by relativistic magnetic reconnection from the evolutionary behavior of the two spectral breaks E
p and E
cut. Meanwhile, the adiabatic cooling process of the emitting particles in the magnetic reconnection regions produces a relation between the spectral index and the flux. We also discuss the physics behind spectral energy correlations. Finally, we argue that the identification of an anticorrelation between E
cut and L
iso may open a new avenue for diagnostics of the physics of the particle acceleration and radiation in a variety of astrophysical sources.
Three Types of Solar Coronal Rain during Magnetic Reconnection between Open and Closed Magnetic Structures
Authors: Qiao Fangfang , Li Leping , Tian Hui , Hou Zhenyong , Song Hongqiang , Ji Kaifan , Sun Zheng
Published: September 2024

Coronal rain (CR) is a crucial part of the mass cycle between the corona and chromosphere. It includes flare-driven CR and two types of quiescent CR, along nonflaring active region closed loops and along open structures, separately, labeled as type I, type II, and type III CR, respectively. Among them, type I and type III CR are generally associated with magnetic reconnection. In this study, employing data taken by the Solar Dynamics Observatory and the Solar Upper Transition Region Imager on 2022 October 11, we report three types of CR during an interchange reconnection between open and closed magnetic field structures above the southeastern solar limb. The open and closed structures converge, with the formation of the current sheet at the interface, and reconnect. The newly formed closed and open structures then recede from the reconnection region. During the reconnection, coronal condensation occurs along the reconnecting closed loops and falls toward the solar surface along both loop legs, as type II CR. Subsequently, condensation happens in the newly formed closed loops and moves down toward the solar surface along both loop legs, as type I CR. Magnetic dips of the reconnecting open structures form during the reconnection. In the dips, condensation occurs and propagates along the open structures toward the solar surface as type III CR. Our results suggest that the reconnection rate may be crucial for the formation of type I and type III CR during reconnection.
Exploring the Small-scale Magnetic Fields in the Atmosphere of HD 49385 by Asteroseismic Analysis
Authors: Wang Yuetong , Li Yaguang , Li Yan , Lin Guifang , Wu Tao
Published: September 2024

Recent asteroseismic studies have shown convincing evidence that magnetic fields may exist in the interior of some pulsating red giants. Inspired by this breakthrough, we explored the effect of small-scale magnetic fields on the p-mode oscillations in an evolved star, HD 49385. We incorporate a modified Eddington T–τ equation that phenomenologically mimics the effect of the magnetic fields in the atmosphere of HD 49385, and calculate the frequencies of p-modes with l = 0, 1, and 2. By comparing the calculated frequencies with the observed ones, we select two best-fit models with either GS98 or A09 chemical composition. Our best-fit models not only fit satisfactorily the observed frequencies but also well reproduce some spectroscopically observed stellar parameters such as effective temperature and log g. Based on the two best-fit models, we have estimated that the small-scale magnetic fields possess a strength of approximately 80 G and spread concentratively at approximately a height of 1850 km in the atmosphere. By selecting the best-fit models with a special requirement on the avoided-crossing mode, we have confirmed that the frequency of the avoided-crossing mode is tightly related to the helium core of the star, and determined the size of the helium core as 0.117 M
⊙ in mass and 0.078 R
⊙ in radius. Based on the improvements of the previous two sides, we can accurately determine the mass of HD 49385 to be 1.25 ± 0.02 M
⊙ with an age of 4.1 Gyr for GS98 composition and 4.5 Gyr for A09 composition.
Dependence of Virial Factors on Optical Spectral Properties of Active Galactic Nuclei
Authors: Yang Sen , Du Pu , Wang Jian-Min
Published: September 2024

Reverberation mapping (RM) has long been a powerful tool for measuring the masses of supermassive black holes (SMBHs) at the centers of active galactic nuclei (AGNs), but the precision of these mass measurements depends on the so-called virial factors. It has been demonstrated that the virial factors exhibit significant diversity, spanning approximately 1–2 orders of magnitude across different AGNs. However, the underlying physical drivers for the diversity have not yet been finalized. Here, adopting the SMBH mass–spheroid luminosity relations of inactive galaxies with different bulge classifications, we calibrate the virial factors corresponding to the AGNs with pseudobulges (PBs) and classical bulges (or elliptical hosts, CBs) using the latest nearby RM sample. We investigate the correlations between virial factors and the AGN spectral properties, and find that for both PB and CB samples, the FWHM-based virial factors exhibit significant anticorrelations with the emission-line widths and profiles, while the σ
line-based virial factors only show moderate anticorrelations with line widths for PBs. We attribute these correlations mainly to the inclination angle or opening angle of the broad-line regions. Moreover, we establish new relations to give more precise virial factors and, in combination with the latest iron-corrected radius–luminosity relation, tentatively develop new single-epoch estimators of SMBH masses, which enable more accurate measurements of SMBH masses in large AGN samples.
Another Independent Discovery of the 1946 Eruption of the Recurrent Nova T Coronae Borealis
Authors: Shears J. H.
Published: September 2024

One of the earliest independent discoveries of the 1946 eruption of the recurrent nova T Coronae Borealis was by British amateur astronomer, Michael Woodman, on 1946 February 9 at ∼01:45 UT when the nova was magnitude ∼2.0. Though credited as an independent discovery at the time, only scant details appeared in contemporary reports. The circumstances of Woodman’s discovery are told from Woodman’s contemporaneous notes and his own recollections.
L’Oréal, l’art d’intégrer des acquisitions
Authors: Carillon Cyrille
Published: September 2024

Les acquisitions de L’Oréal ont enregistré, ces dix dernières années, une hausse significative. Toutefois, intégrer une nouvelle marque, souvent jeune et fragile, dans une organisation multinationale aux exigences éthiques, environnementales et de protection du consommateur croissantes est un exercice complexe. Cela suppose une rigueur dans les due diligence et les synergies projetées, le financement d’équipes pluridisciplinaires d’intégration, mais aussi et surtout transparence, éthique et générosité dans l’accompagnement.
Lady of Shalott revisitée. L’internalisation de la fonction-auteur à l’ère des créations artificielles
Authors: Michaux Clarisse
Published: September 2024

Soit deux peintures identiques, l’une réalisée en 1888 par Waterhouse, l’autre par une intelligence artificielle. Si ces deux peintures sont indiscernables sur le plan perceptif, sont-elles distinctes sur le plan ontique ? Une telle différence est-elle susceptible d’affecter leur réception spectatorielle ? Dans cette expérience de pensée, sont envisagés trois axes depuis lesquels on pourrait supposer des différences structurelles entre la réception spectatorielle des deux œuvres : la représentation, l’interprétation des choix auctoriaux et la contrainte interprétative. À la faveur de ces questions ponctuelles, se pose une question transversale – celle de la prise en compte de l’auteur dans la réception des œuvres et de la persistance de sa figure en dépit de sa disparition factuelle.
L’esthétique est née de la rétrogradation (relative) du beau. Contribution à la connaissance de l’œuvre philosophique de Lord Shaftesbury
Authors: Chateau Dominique
Published: September 2024

Shaftesbury, dès la charnière du xvii e et du xviii e siècle, a anticipé diverses théories ensuite réputées plus ou moins inédites ou novatrices. Notamment, par la prise en compte, au sein d’une théorie du beau d’inspiration antique soutenue par une philosophie de la nature néo-platonicienne, des anomalies naturelles, des spectacles grandioses, des formations monstrueuses. S’y ajoute une théorie de la forme formée/formante qui anticipe la théorie de la formativité de Luigi Pareyson.
Analyse du statut épistémologique de l’intérêt public : la délicate émergence d’une volonté « commune »
Authors: Antonicelli Léa
Published: September 2024

L’intérêt public est au cœur de la sémantique politique : le syntagme est omniprésent dans les pratiques discursives du droit et de l’administration publics ainsi que dans les discours rhétoriques et polémiques des acteurs du débat public. Pourtant, s’il constitue un élément de langage fondamental, son contenu a rarement été défini : ce sont les usages à travers le temps qui peuvent en indiquer le sens, mais ce sens, pour n’avoir pas été explicitement posé, demeure nécessairement incertain et peut varier selon les contextes, les énonciateurs et les destinataires à qui il est adressé.La difficulté sémantique tient à l’apposition quasiment oxymorique du terme d’« intérêt » – qui, logiquement, devrait être relatif à chaque individu – et de celui de « public » uni, uniforme et homogène. Sur quel fondement comment peut-on dégager un contenu objectif à l’expression ? Peut-il être suffisamment précis et solide pour être le fondement de la légitimité politique, peut-il être le critère pour déterminer si la réalisation d’une politique publique est justifiée ou pas ? L’imprécision sémantique empêche-t-elle d’établir l’existence d’un concept politique d’intérêt commun ? C’est donc le statut épistémologique de l’intérêt public qu’il convient de questionner in fine : il nous faut déterminer de quel type d’objet épistémologique il s’agit pour saisir à quelles fins il est manipulé dans les pratiques discursives. Il s’agira dans cet article de développer la thèse selon laquelle l’intérêt public n’est pas un concept scientifique à proprement parler, ni une catégorie, ni même une expérience politique pure, il est éventuellement un concept au sens politique du terme, à comprendre comme une structure langagière, une fiction régulatrice toujours en cours de formation, historiquement élaborée en réponse à une anthropologie rationnelle. Pour cela, on mettra en évidence, dans un premier moment, l’absence de définition du prétendu concept d’intérêt public. Dans un second temps, nous expliquerons sa persistance paradoxale non seulement dans les discours politiques mais aussi dans les discours théoriques en revenant sur les étapes les plus importantes de la généalogie du concept. Finalement, nous pourrons développer les difficultés que suppose la qualification épistémologique de la notion « d’intérêt public » et proposer une interprétation de son statut.
Persistent homology of featured time series data and its applications
Authors: Heo Eunwoo , Jung Jae-Hun
Published: September 2024

Recent studies have actively employed persistent homology (PH), a topological data analysis technique, to analyze the topological information in time series data. Many successful studies have utilized graph representations of time series data for PH calculation. Given the diverse nature of time series data, it is crucial to have mechanisms that can adjust the PH calculations by incorporating domain-specific knowledge. In this context, we introduce a methodology that allows the adjustment of PH calculations by reflecting relevant domain knowledge in specific fields. We introduce the concept of featured time series, which is the pair of a time series augmented with specific features such as domain knowledge, and an influence vector that assigns a value to each feature to fine-tune the results of the PH. We then prove the stability theorem of the proposed method, which states that adjusting the influence vectors grants stability to the PH calculations. The proposed approach enables the tailored analysis of a time series based on the graph representation methodology, which makes it applicable to real-world domains. We consider two examples to verify the proposed method's advantages: anomaly detection of stock data and topological analysis of music data.

Ser mulher: discursos veiculados nas revistas “O Jovem Luterano” e “O Cruzeiro” (1950-1960)
Authors: Alvares Teixeira Tania Nair , Kruger Albrecht Elias , Weiduschadt Patrícia
Published: September 2024

O presente estudo tem como objetivo abordar a educação feminina por meio de discursos publicados numa revista religiosa luterana juvenil denominada O Jovem Luterano, e numa revista cultural e de entretenimento conhecida como O Cruzeiro. Considerando as particularidades dessas publicações, a perspectiva adotada foi explorar os discursos moralizantes, normativos e prescritivos em relação ao comportamento das mulheres e ao papel social que lhes é atribuído. As edições referentes aos anos de 1950 e 1960 foi escolhida  pois se observa uma maior disseminação de discursos voltados a orientar as experiências domésticas e sociais das jovens e mulheres; discursos que buscaram caracterizar, assim, a função social e biológica da mulher enquanto esposa, mãe e dona de casa. Tais discursos revelam as várias formas de processos educativos nesse sentido, tanto de ensino regular quanto no que diz respeito ao papel das mulheres na construção do fazer e do pensar feminino dentro da sociedade.
Sustentabilidade e governança transnacional como elementos para a adoção de novas matrizes energéticas
Authors: Marcio Cruz Paulo , Silva Antunes de Souza Maria Cláudia
Published: September 2024

A presente pesquisa tem por objetivo investigar a sustentabilidade como novo paradigma indutor do direito na pós-modernidade, nas dimensões social, econômica e ambiental, ao tempo que contribui na ressignificação da matriz energética, com a apresentação de alternativas viáveis de diversificação de novas energias ecológicas. A relevância acadêmica e social do presente texto encontra-se no fato de que o progresso da eficiência energética, já lento, enfrenta retrocessos, como a diminuição das melhorias globais em eficiência energética desde 2015, as quais afetam diretamente as metas para o clima e, por consequência, a sustentabilidade, em suas três dimensões. O problema de pesquisa tem seu foco em investigar se a sustentabilidade como novo paradigma jurídico terá melhores condições de promover o socioambientalismo, a inclusão, a justiça social e mais qualidade de vida, por meio da mudança da matriz energética, tendo como âmbito de análise o Brasil.  Quanto à metodologia, tanto na fase de investigação quanto na fase de relatório dos resultados, o método empregado é o indutivo.
Pamprincipiologismo e Direito no Estado Democrático
Authors: Sampar Rene , De Oliveira Lima Newton , Henrique Kroth Eduardo
Published: September 2024

O artigo, através de pesquisa bibliográfica, define três conceitos de princípios jurídicos:  epistemológico, como princípios gerais do Direito e pragmático-problemáticos. Defende a tese da ruptura entre o segundo e o terceiro conceitos, de modo que os princípios constitucionais do pós-guerra são a inserção do mundo prático no Direito. Estes princípios são institucionalizados a partir da moralidade política compartilhada pela comunidade e são, fundamentalmente, dotados de historicidade. Seus sentidos dependem dos pré-juízos derivados da tradição intersubjetiva, e não da razão prática solipsista e axiológica dos princípios gerais do Direito. A autenticidade desta tradição e dos significados que dela decorrem depende da adequação dos critérios de decisão à Constituição e da própria compreensão de que princípios, enquanto instituidores de regras e da moralidade pública, são limites. Entender o contrário fere a autonomia do Direito e retira das decisões sua legitimidade, na medida em que localiza na consciência subjetiva do intérprete o sentido dos conceitos, tornando-os inverificáveis, e eleva como princípios quaisquer enunciados (o pamprincipiologismo). Entender a tese da ruptura é compreender que o Direito deve ser democraticamente legítimo, e que dentro dele todas as interpretações devem ser adequadamente fundamentadas, garantindo sua autonomia e legitimidade.
De la vérité au procès : les effets de la justice transitionnelle dans le temps
Authors: Philippe Xavier
Published: September 2024

La confrontation d'une société à un passé violent n'est jamais aisée. Alors que pendant des décennies, la loi du silence a régné, certains pays d'Amérique latine - au premier rang desquels l'Argentine - ont eu le courage de mettre en place des processus inédit de façon à connaître la vérité sur ce passé. Si ce processus est douloureux pour les victimes, il l'est également pour la société toute entière qui doit se reconstruire. Or, la connaissance de la vérité peut également se révéler utile plusieurs décennies plus tard lorsque les procès des responsables sont devenus possibles. Souvent décriée comme un marchandage contre la punition du coupable, la justice transitionnelle peut devenir avec le temps une alliée précieuse pour que justice soit rendue.

Authors: Henriques Joana , Moura Rita , Gonçalves Sónia P.
Published: September 2024

University students are particularly prone to mental health issues such as anxiety and depression, in part due to their transition to emerging adulthood and higher education. Recent studies have established that a considerable number of students go through mild-to-severe episodes of depression, anxiety, and stress during their university years. Despite the exponential increase in interest in this problem, an integrated overview is still lacking. The initial sections of the present review aim to: (i) give an updated view of the state of the art regarding university students' mental health; (ii) present the prevalence and associated consequences of mental health issues, (iii) identify the risk and protectives factors; and (iv) summarize the types of interventions available. The concluding section focuses on making recommendations for the future and proposes new research directions based on the identified literature gaps, namely courses of action, help-seeking behaviours and mental health literacy, and positive mental health.
Balancing the Tedious See-Saw of Academic Pressure and Personal Growth
Authors: Nayak Anusha P. , Kachhi Zidan
Published: September 2024

Academic pressure is precisely described as a situation in which a student is burdened by time and energy demands to attain certain academic goals. Personal growth is the process of learning new abilities, attitudes, behaviours, or emotions that can improve an individual's life and overall well-being. Maintaining an equilibrium between academic pressure and personal growth is tricky and difficult to navigate through, but essential nonetheless. Taking a holistic approach to education entails focusing on all elements of a child's development, not simply academic achievements. Long gone are the days when grades and marks were considered the red stamp on the futures of children. This holistic approach in the current education system demands strategies to balance academic pressure and personal growth. The chapter aims to analyze the strategies that can be used to balance academics and personal growth by individually analyzing both aspects. The critical paradigm is consistent with the goal of addressing social justice issues and pushing for a more humanistic educational environment.

Examining Human Resource Management With the Bibliometric Analysis Method
Authors: Angin Cem
Published: September 2024

Human resources management refers to the organizational and managerial activities covering the processes of recruitment, training, development and adaptation of personnel, which is one of the most basic needs of an organization, to the objectives of the organization. Human resources management, which symbolizes a break from the classical understanding of personnel management, first emerged in the private sector and then spread to public administration. For both the private and public sectors, the human element is now of “strategic” importance. This importance has been a development that has brought human resource management to the forefront today. This study focuses on the bibliometric analysis of studies in the field of human resource management. The study will present a multidimensional analysis of the studies conducted in the field of human resource management in the world. In this context, the study aims both to guide academics and researchers who will work in this field and to open the door to new studies by revealing the shortcomings and gaps in this field.
Analyzing Foam Injection Dynamics in Porous Media: A Combined Computational and Experimental Approach
Authors: Werneck Yan  Barbosa , Motta Luciana Paixão , de Bastos Flavia , dos Santos Rodrigo Weber
Published: September 2024

The study of foam injection dynamics into porous media holds numerous applications, with its primary use being the optimization of the oil extraction process. Additionally, it finds utility in various other domains, including soil decontamination techniques. This study focuses on evaluating foam injection through low-cost experiments and computational models. The model integrates a classic two-phase immiscible fluid flow in a porous media framework, augmented by a mobility reduction factor to simulate foam’s impact on gas phase mobility. Simple experiments were conducted to assess water displacement using both gas and gas-foam injection methods. Results revealed that while gas injection tends to form preferential paths rapidly, leading to gas disruption, foam injection generates a more compact front, enhancing sweep efficiency by mitigating preferential path formation. The computational model successfully reproduced the experimental findings qualitatively. This research introduces a cost-effective experiment suitable for didactic purposes, illustrating complex concepts and underscoring the complementary nature of experimental and computational methodologies in advancing engineering techniques.

Abstract. Water is a natural and essential resource for life and must be preserved. Its potability is also vital for human survival. In this context, the turbidity parameter is a factor preponderant, as its presence can “protect” harmful microorganisms during the disinfection. Considering the extensive volume of data collected by Pelotas Autonomous Service of Sanitation at the Santa Bárbara Water Treatment Plant over the years, it was proposed to develop a methodology to support decision-making by managers, through data processing using statistical methods, machine learning and time series. Studies have shown that turbidity is an essential parameter in quality monitoring of the water andcan be inferred before the filtration stage from data collected throughout time. Furthermore, using data from the treatment plant itself offers the advantage of taking its peculiarities into account in the analysis.

High-fidelity computational simulations have been performed which focus on rotor-fuselage and rotor-rotor aerodynamic interactions of small quad-rotor vehicle systems. The three-dimensional unsteady Navier-Stokes equations are solved on overset grids using high-order accurate schemes, dual-time stepping, low Mach number preconditioning, and hybrid turbulence modeling. Computational results for isolated rotors are shown to compare well with available experimental data. Computational results in hover reveal the differences between a conventional configuration where the rotors are mounted above the fuselage and an unconventional configuration where the rotors are mounted below the fuselage. Complex flow physics in forward flight is investigated. The goal of this work is to demonstrate that understanding of interactional aerodynamics can be an important factor in design decisions regarding rotor and fuselage placement for next-generation multi-rotor drones.
