Political partition of Kurdistan
Authors: Vasiliva Evgenia Ilinyna
Published: February 2025

The political partiton of Kurdistan, initiated by the Ottoman-Safavid battle of Çaldıran in 1514, shaped the region’s destiny for centuries. Vasiliva E.I.’s Political Partition of Kurdistan 1514–1914 examines the historical processes that led to the fragmentation of Kurdish lands between the Ottoman and Persian empires. The book highlights how this division was not merely a consequence of imperial conflicts but a deliberate geopolitical strategy to undermine Kurdish unity. Drawing on historical sources, the author traces the struggles of Kurdish rulers, the impact of shifting allegiances, and the suppression of Kurdish identity. She explores the role of key figures such as Emir Sharaf Bidlisi and Idris Bidlisi, and the long-term consequences of treaties like the 1639 Zohab Agreement, which formalized Kurdistan’s division. The study reveals how the imposed borders disrupted Kurdish socio-economic structures, affecting tribes, emirates, and cultural development. This seminal work, now translated into Kurdish by Dr. Kamran AminAve and published by the TISHK Center for Kurdistan Studies, offers a critical historical perspective on the partition that continues to define Kurdish geopolitics today.

Abstract
Background: E-cadherin gene plays an important role in the carcinogenesis of laryngeal squamous cell carcinoma (LSCC). This study aimed to evaluate the immunohistochemical expression of E-cadherin in different grades and clinical stages of LSCC and to determine the association of E-cadherin with clinical stages and histopathological grades.
Methods: This cross-sectional study was conducted in the Department of Pathology, Sylhet MAG Osmani Medical College, from March 2021 to January 2023. Immunohistochemistry was performed in 50 histopathologically diagnosed cases of LSCC using a commercially available anti-E-cadherin antibody. The total score of immunoreaction was calculated by multiplying the expression score and intensity score.
Results: The mean age of the LSCC patients was 62.8 years, and 66% were male. Grade I is the most frequent histopathological grade (48%), followed by grade II (42%) and grade III (10%). The most frequent clinical T stage was T3 (56%), and the N stage was N2 (58.06%). E-cadherin expression was positive in 72% of cases; the rest, 28%, showed reduced expression. A significant association was found between E-cadherin expression with histopathological grades (p=0.007) and clinical N stage (p=0.009) but not significant with clinical T stage (p=0.502), anatomic site (P=0.132), and the habit of smoking (0.276).
Conclusion: LSCC patients with reduced E-cadherin expression are at the risk of high-grade carcinoma and nodal metastasis. So, the expression of E-cadherin in pre-treatment biopsy samples can be utilized as one of the prognostic factors and advocated to anti-E-cadherin targeted therapy in LSCC.

Moderating Effect of Environmental Contingency Factors on the Relationship Between Path Goal Leadership and Performance of Manufacturing Small and Medium Enterprises in Kenya
Authors: Ochieng Lucy Atieno , Koshal Jeremiah , Bellows Scott
Published: February 2025

This study sought to examine the moderating effect of environmental contingency factors on the relationship between path-goal leadership style and performance in manufacturing SMEs in Nairobi.  The target population comprised of managers/owners from 425 SME’s listed members of the Kenya Association of Manufacturers based in Nairobi region.  A sample size of 369 managers/owners was derived using stratified random sampling technique.  Data was collected using self-administered questionnaires. Binary logistic regression (Cox and Snell R Squared) was used and results indicated that the environmental contingency factors explain 16.5 % of the probability of the relationship between path-goal leadership style and organizational performance. The parameter estimates showed that the coefficient of path-goal leadership styles by environmental contingency factors were; directive leadership (2.935, p =.112), supportive leadership (-.427, p =.717), participative leadership (-.4.645, p = 0.046), achievement oriented leadership style (2.586, p = 0.118). Hence, the study failed to reject the null hypothesis that environmental contingency factors do not significantly moderate the relationship between path goal leadership style and organizational performance in three study variables (directive, supportive and achievement oriented leadership styles). However, the study rejected the null hypothesis that environmental contingency factors do not significantly moderate the relationship between participative leadership style and organizational performance.  The study revealed that environmental contingency factors did not significantly moderate the relationship in three path goal leadership styles (directive, supportive and achievement-oriented leadership style) and organizational performance while it significantly moderated the relationship between participative leadership style and organizational performance in manufacturing SMEs in Nairobi. Therefore, the study recommends that owners/ managers of manufacturing SME need to define the tasks and duties to be performed, instruct employees on how to carry out tasks and duties and build a cohesive team to carry out tasks especially when they apply participative leadership style to realize optimal organizational performance.

Published: February 2025

Student transition from academia to productive and professional workforce remains a critical challenge for youth employment. There exists an ongoing philosophical debate within academia regarding prioritization of lifelong learning over employability skills. This action research-based paper explores the impact of academic-to-industry bridging programs, with a focus on the Cyber Shujaa program. The program aimed to bridge academia-industry gap by providing transitional skills and capacity building that facilitates employment through job placements, entrepreneurship, and career advancement while promoting gender mainstreaming The research answers the question of whether academic to industry bridging programs help their beneficiaries attain meaningful employment and entrepreneurial opportunities. The research was informed by the Theory of Change which hypothesized that the program design features contribute to youth performance which in turn results into youth employment, gender participation and youth confidence, and ultimately influencing youth socio-economic empowerment. The study employed a descriptive correlation research design. The findings indicated that the program had a significant and positive impact on participants' employment readiness and technical skill application. Additionally, gender analysis revealed no statistically significant difference in employment outcomes, suggesting that the program’s gender mainstreaming approach successfully supported equitable career development. However, moderate satisfaction with employment preparation and placement suggested areas where enhancements could be made. Participants also reported a strong sense of purpose in pursuing cybersecurity careers, which positively correlated with their confidence levels. These findings underscored the importance of combining robust technical training with industry-based purpose-driven program components to enhance professional confidence, employability, and overall career satisfaction. This paper contributes to the ongoing dialogue on how to better equip young graduates for the demands of the industry, ultimately fostering a more inclusive, confident, and effective workforce.

Authors: BHATIA RAHUL
Published: February 2025

The article analyses combining SAP S/4HANA with machine learning to automate and evaluate real-time data and enhance decision-making in financial processes. SAP S/4HANA, a complex ERP system, uses machine learning technologies. These mathematical models attempt to change financial operations by improving forecasts, identifying irregularities, and automating transactions. Artificial Intelligence-driven automation has improved financial forecast accuracy, employee involvement reduction, and fraud detection. Management teams at the bank put financial systems in place that made transactions flow better and helped them make smart choices, saving money and time. The system works at top quality despite the Cloud service provider’s changes in capacity to match demand. The system integration leads to better financial tracking while managing resources effectively and generating useful analysis from data. The future project plan includes strengthening database administration technologies, making AI modules available in SAP S/4HANA, and developing advanced models to identify problems. Future research will check system interconnection and data control methods to help enhance financial processes.  The paper examines how joining SAP S/4HANA with machine learning creates fresh ways to automate difficult work and generate better financial operation forecasts. The article minimized workflow slowdowns while improving both financial decision-output times and how spending proceeds are tracked. By analysing financial data efficiently, the system supported financial corporations to monitor resources better while dodging errors. By including AI and Cloud technologies, the system gained proper scalability and used resources effectively as businesses grew without hurting system speed.
De la technique comme onto-phénoménologie à l’ère moderne
Authors:   Université Félix HOUPHOUËT-BOIGNY (Côte d’Ivoire), NANOU Mamboh Mathieu
Published: February 2025

Heidegger pense la manière dont l’Être s’est dispensé et a été compris, depuis ce qu’il appelle le commencement grec jusqu’à notre époque, qualifiée de temps modernes. Comprendre notre époque comme l’avènement de l’homme moderne, nous permet de comprendre le mouvement de la phénoménologie qui prône le « retour à la chose même ». Heidegger montre la continuité et l’enchaînement rigoureux qui lient l’homme de la Technique et l’homme-sujet. Celui qui a voulu devenir comme « maître et possesseur de la nature » est devenu celui qui obéit aveuglément au projet de la Technique sur lui. Il nous incombe, donc, de recourir à une phénoménologie du dévoilement, de sorte à bien appréhender la technique moderne et post-moderne comme des formes actuelles du manifester de l’Être.
Être et avoir : enjeux du plein accomplissement africain à la lumière de la pensée de Gabriel Marcel
Authors:   Université Alassane OUATTARA (Côte d’Ivoire), KOUASSI Moulo Elysée
Published: February 2025

La vie est une réalité identifiée à la conscience d’une plénitude d’être. Mais la poursuite de cette plénitude, mal négociée, peut conduire à un mal-être, c’est-à-dire à l’inquiétude, à l’insécurité de l’être ; car l’exigence d’être peut s’exténuer, se détériorer si une intuition véritable de la dialectique de l’Avoir et de l’Etre n’est pas assimilée. Selon la phénoménologie marcellienne, la tragédie de l’Avoir explique mieux la véritable mutilation dans le développement de l’homme et de la société. Dès lors, cette réflexion sur le mal-être en Afrique, à partir d’une approche phénoménologique et critique, déconstruit la mauvaise signification rattachée à l’Avoir et se propose de penser une éthique de l’être-au-monde susceptible de rendre les Africains responsables et de contribuer à la création d’un environnement éthique et politique durable.
Droits de l’homme et hospitalité universelle chez Kant : repères pour l’accueil des migrants
Authors:   Université de Lomé (Togo), TONYEME Bilakani
Published: February 2025

Kant a été l’un des premiers à démontrer que tout homme, en tout temps et en tout lieu, constitue une individualité une fin en soi. Cette idée qui est au fondement des droits de l’homme est admise par la modernité comme devant guider la conduite humaine. Elle a très largement contribué à la justification philosophique des droits de l’homme. Ceci implique que tout homme soit traité, non comme un moyen, mais comme une fin. C’est l’une des sources de l’humanisme du siècle des Lumières. Or de nos jours, au nom d’une certaine protection territoriale, les migrants sont soumis à toute sorte de traitements inhumains, en violation du principe d’une de l’hospitalité universelle postulée par Kant. Ceci oblige des groupes entiers d’humains à errer sans secours pour périr dans les guerres, entre les mains des bandes de passeurs et d’escrocs, à sombrer dans les eaux des mers ou à finir au mieux dans des camps. Cette contribution vise, en revisitant l’humanisme kantien basé sur le fondement universel et rationnel des droits de l’homme postulé par Kant, à proposer des pistes pour un accueil des migrants qui fait de ceux-ci une fin en soi et non un simple moyen.

Published: February 2025

Dans cette contribution, nous nous intéressons à l’enseignement et à l’évaluation lors d’activités scolaires de transmission de textes par la modalité orale à l’entrée à l’école dans des contextes multilingues. Nous analysons des activités qui relèvent de l’écoute et des échanges oraux d’élèves âgés de cinq ans avec leur enseignant·e à propos de la compréhension d’albums de littérature de jeunesse. Nos analyses montrent que l’enjeu des interactions orales dans la professionnalisation des enseignant·es réside dans la délimitation d’un espace de parole commun et partagé entre l’enseignant·e et le collectif de la classe et que le système récit-personnages fournit un canevas de pensée pour structurer ces interactions dans des contextes hétérogènes et plurilingues.

La compétence à communiquer oralement est indispensable à la vie en société. Pourtant, en Belgique francophone, elle est peu enseignée et peu évaluée tant dans l’enseignement obligatoire que dans la formation initiale des enseignants, alors même qu’elle est sollicitée en stages et en formation. Nos questions de recherche sont les suivantes : quand et comment est enseigné et évalué l’oral en formation des enseignants ? Y a-t-il un lien entre les croyances des formateurs et leurs pratiques. Afin d’y répondre, le portrait et les croyances de formateurs ont été identifiés par une analyse de contenu.
Comprendre les ressorts de la création de valeur territoriale. Vers une approche socioterritoriale des fonctionnalités
Authors: Maillefert Muriel , Serra Lise
Published: February 2025

La création de richesse repose aujourd’hui principalement sur les services qui mobilisent une dynamique de co-construction de la valeur. Cette propriété, mise en avant par les travaux sur l’économie des services mais peu exploitée dans les travaux d’aménagement et d’urbanisme, modifie les relations entre les acteurs, notamment entre le producteur et l’usager et introduit dans le cas de services territorialisés (comme la mobilité, l’alimentation, l’habitat, la santé) de nouveaux enjeux de création de richesse autour d’acteurs hétérogènes à l’échelle de territoires. Ce travail vise à définir ce qui apparaît comme original dans ces nouveaux modèles de développement rattachés à l’économie circulaire, en prenant l’exemple de l’un d’entre eux, le modèle de l’économie de la fonctionnalité. Il tente de le caractériser et d’en identifier les potentialités transformatives en proposant une approche territorialisée du fonctionnement des économies. Un des leviers est de réfléchir à une caractérisation des fonctionnalités comme rapport social. L’enjeu de cette réflexion autour des nouveaux modèles serviciels est de proposer des clés de lecture pour discuter de la dimension constructiviste et transformative de ces modèles spatialisés.

Le GRIS-Montréal est un organisme communautaire qui intervient par le témoignage dans une diversité de milieux, notamment scolaires, afin de démystifier les orientations sexuelles ainsi que les identités trans et non binaires. Lors de ses interventions, l'organisme recueille par questionnaire des données qui sont ici analysées afin de dégager les représentations de jeunes adultes étudiant au collégial ou à l'université concernant les personnes trans et non binaires (TNB). La présente étude s’appuie sur une analyse qualitative thématique des réponses à court développement issues de 689 questionnaires. Les résultats s’articulent autour de trois volets, soit 1) les définitions offertes à propos des personnes TNB comme révélatrices du niveau de compréhension des jeunes adultes; 2) les attitudes à leur endroit, qui témoignent d’une variété de postures à l’égard de la pluralité des genres et 3) les représentations des jeunes adultes, où les réalités des personnes trans sont ancrées plus particulièrement dans des dimensions liées au corps et à l’idée de passage (devenir), tandis que celles des personnes non binaires sont plutôt associées à la notion d’identité.
Comment les jeunes adultes inscrits en formation professionnelle au Québec perçoivent-ils le soutien de leurs parents ?
Authors: Deschenaux Frédéric , Courcy Julie , Molgat Marc , Cournoyer Louis
Published: February 2025

Le soutien parental s’avère un sujet moins documenté en formation professionnelle (FP) qu’aux autres ordres d’enseignement. Ainsi, à partir d’une analyse thématique de 80 entretiens conduits auprès de jeunes adultes inscrits en FP, cet article vise à répondre à la question suivante : quels types de soutien les jeunes adultes inscrits en formation professionnelle estiment-ils recevoir de la part de leurs parents? L’analyse permet de présenter les formes de soutien parental et d’élaborer une typologie qui dégage quatre différentes formes d’attitudes parentales face aux parcours de leurs enfants comme autant de manières d’accorder du soutien : encourageante, exigeante, inquiète et contrôlante. Considérée sous l’angle du capital social et des attitudes parentales, l’analyse montre des répercussions sur le parcours scolaire et illustre les processus par lesquels le capital relationnel de ces jeunes peut produire une insertion professionnelle plus ou moins stable tout en reproduisant des inégalités.

Authors: Chan Jason , Hu Qinran
Published: February 2025

With the continuing development of the smart grid combined with the fluctuating nature of the electricity market, the development of demand-side management with controllable loads have been greatly driven. With the amount of household loads in the residential sector, managing their energy usage has received lots of interest. This paper presents a simulation of a previously proposed hardware design of a smart home energy management system (SHEMS), focusing on the data collection and processing functions of the proposed design while implementing them onto standard household loads like an electric water heater and an electric vehicle charging station. It was found that the simulation of the loads save consumers money by a significant amount when an SHEMS is implemented when compared to without implementation of an SHEMS.

Authors:   Universitas Indonesia, Ningrat Achmad Raihan Suryadi
Published: February 2025

The growth of tourism in Indonesia has positively impacted the hospitality sector, particularly in the kitchen department which is in charge of providing food and beverages to guests. Kitchen Hotel Holiday Inn Kemayoran wants to optimize the use of food scraps to control expenses without compromising food quality and hygiene. The results showed that there was a waste of food ingredients at the butcher and commissary in the hotel's main kitchen, such as chicken bones, shrimp shells, and vegetable ingredients. However, the leftovers can be processed with creative use into new dishes that reduce waste. This study provides theoretical benefits as a reference in utilizing leftover food ingredients in the Holiday Inn Kemayoran hotel kitchen, as well as practical benefits in reducing expenses and increasing hotel spending control. By managing food waste effectively, Hotel Holiday Inn Kemayoran can achieve better expense control, maintain operational sustainability, and reduce the negative impact on the environment.
Zeno's paradox and black hole information loss problem
Authors: Ge Xian-Hui  ,   Department of Physics, College of Sciences, Shanghai University, Shanghai 200444, China
Published: February 2025

The black hole information paradox—a fundamental conflict between quantum unitarity and semi-classical gravity—remains unresolved within the framework of quantum gravity. This work establishes a conceptual bridge between this modern dilemma and Zeno’s ancient paradox of motion, emphasizing their shared dependence on limit processes to reconcile infinite divisibility with finite physical outcomes. While prior works established information conservation in black hole evaporation via replica wormholes, this study transcends mere unitarity verification to address a deeper question: How do we quantify the statistical evolution and inherent irreversibility of Hawking radiation?

A dramatic shift from aggressive infanticidal to paternal behaviors is an essential event for male mice after mating. While the central part of the medial preoptic area (cMPOA) has been shown to critically mediate the paternal behaviors in mice, how this brain region becomes activated by mating and subsequent interaction with pups has not been investigated. Here, we demonstrate that the reduction in inhibitory synaptic strength towards the cMPOA provided by posterior-dorsal medial amygdala (MePD) neurons is a key event for the post-mating behavioral shift in males. Consistent with this, we found optogenetic disinhibition of Me
Cartpt
to the cMPOA synapses reduces male aggression towards pups. The cMPOA of paternal mice mediated pup-induced neural plastic changes in the bed nucleus of the stria terminalis. These findings provide possible functions of cMPOA neural circuits required for the reception to young in male mice.

A well-known phenomenon in the optogenetic toolbox is that all light-gated ion channels, including red-shifted channelrhodopsins (ChRs), are activated by blue light, whereas blue-shifted ChRs are minimally responsive to longer wave-lengths. Here, we took advantage of this feature to create a system which allows high-frequency activation of neurons with pulses of red light, while permitting the suppression of action potentials with millisecond precision by blue light. We achieved this by pairing an ultrafast red-shifted ChR with a blue light-sensitive anion channel of appropriately matching kinetics. This required screening several anion-selective ChRs, followed by a model-based mutagenesis strategy to optimize their kinetics and light spectra. Slice electrophysiology in the hippocampus as well as behavioral inspection of vibrissa movement demonstrate a minimal excitation from blue light. Of significant potential value, in contrast to existing tools, the system we introduce here allows high frequency optogenetic excitation of neurons with red light, while blue light suppression of action potentials is confined within the duration of the light pulse.
Inhibiting NINJ1-dependent plasma membrane rupture protects against inflammasomeinduced blood coagulation and inflammation

Published: February 2025

Systemic blood coagulation accompanies inflammation during severe infection like sepsis and COVID. We’ve previously established a link between pyroptosis, a vital defense mechanism against infection, and coagulopathy. During pyroptosis, the formation of gasdermin-D (GSDMD) pores on the plasma membrane leads to the release of tissue factor (TF)-positive microvesicles (MVs) that are procoagulant. Mice lacking GSDMD release fewer TF MVs. However, the specific mechanisms leading from activation of GSDMD to MV release remain unclear. Plasma membrane rupture (PMR) in pyroptosis was recently reported to be actively mediated by the transmembrane protein Ninjurin-1 (NINJ1). Here we show that NINJ1 promotes procoagulant MV release during pyroptosis. Haploinsuffciency or glycine inhibition of NINJ1 limited the release of procoagulant MVs and inflammatory cytokines and partially protected against blood coagulation and lethality triggered by bacterial flagellin. Our findings suggest a crucial role for NINJ1-dependent PMR in inflammasome-induced blood coagulation and inflammation.
Improved base editing and functional screening in Leishmania via co-expression of the AsCas12a ultra variant, a T7 RNA polymerase, and a cytosine base editor

Published: February 2025

The ability to analyze the function of all genes in a genome is highly desirable, yet challenging in Leishmania due to a repetitive genome, limited DNA repair mechanisms, and lack of RNA interference in most species. While our introduction of a cytosine base editor (CBE) demonstrated potential to overcome these limitations (Engstler and Beneke, 2023), challenges remained, including low transfection efficiency, variable editing rates across species, parasite growth effects, and competition between deleterious and non-deleterious mutations. Here, we present an optimized approach addressing these issues. We identified a T7 RNAP promoter variant ensuring high editing rates across Leishmania species without compromising growth. A revised CBE single-guide RNAs (sgRNAs) scoring system was developed to prioritize STOP codon generation. Additionally, a triple-expression construct was created for stable integration of CBE sgRNA expression cassettes into a Leishmania safe harbor locus using AsCas12a ultra-mediated DNA double-strand breaks, increasing transfection efficiency by ~400-fold to 1 transfectant per 70 transfected cells. Using this improved system for a small-scale proof-of-principle pooled screen, we successfully confirmed the essential and fitness-associated functions of CK1.2, CRK2, CRK3, AUK1/AIRK, TOR1, IFT88, IFT139, IFT140, and RAB5A in Leishmania mexicana, demonstrating a significant improvement over our previous method. Lastly, we show the utility of co-expressing AsCas12a ultra, T7 RNAP, and CBE for hybrid CRISPR gene replacement and base editing within the same cell line. Overall, these improvements will broaden the range of possible gene editing applications in Leishmania species and will enable a variety of loss-of-function screens in the near future.

Authors: Memoona  , Kim Sung Won
Published: February 2025

The 802.11ax standard introduces Orthogonal Frequency Division Multiple Access (OFDMA), shifting the role of access points (APs) in Wi-Fi networks. This shift integrates intricate scheduling logic, assigning coordinator roles to APs for multi-user uplink (MU-UL) transmissions and streamlining downlink traffic flows. These developments require robust network analysis and simulation tools to investigate the trade-offs associated with using OFDMA. In this study, we validate the implementation of OFDMA in ns-3 Wi-Fi module, enhancing flexibility and support for future updates through a redesign process. Previous studies validate the OFDMA implementation in the ns-3 Wi-Fi module by matching the simulation to predictions of analytical models. In this work, we demonstrate that OFDMA performance aligns with analytical predictions through simulation-based performance evaluations using ns-3 in some contention-driven use cases. The proposed system operates in both the uplink (UL) and downlink (DL) directions, implementing two scheduling logics to manage DL traffic flows and coordinate MU-UL transmissions. Simulation time is reduced by introducing parallel computing in the system. This study provides a reliable network analysis and simulation framework that thoroughly examines the trade-offs involved in using OFDMA.
Dynamic Periodic Event Graphs for multivariate time series pattern prediction
Authors: Park SoYoung , Lee HyeWon , Lim Sungsu
Published: February 2025

Understanding and predicting outcomes in complex real-world systems necessitates robust multivariate time series pattern analysis. Advanced techniques, such as dynamic graph neural networks, have shown significant efficacy for these tasks. However, existing approaches often overlook the inherent periodicity in data, leading to reduced pattern or event prediction accuracy, especially in periodic time series. We introduce a new method, called dynamic Periodic Event Graphs (PEGs), to tackle this challenge. The proposed method involves time series decomposition to extract seasonal components that capture periodically recurring patterns within the data. It also uses frequency analysis to extract representative periods from each seasonal component. Additionally, motif patterns, which are recurring sub-sequences in the time series data, are extracted. These motifs are used to define event nodes using the representative periods extracted from the seasonal components. By constructing periodic motif pattern-based dynamic bipartite event graphs, we specifically aim to enhance the performance of link prediction tasks, leveraging periodic characteristics in multivariate time series data. Our method has been rigorously tested on multiple periodic multivariate time series datasets, demonstrating over a 5% improvement in link prediction performance for both transductive and inductive scenarios. This demonstrates a substantial enhancement in predictive accuracy and generalization, providing confidence in the technique’s effectiveness. Reproducibility is ensured through publicly available source code, enabling future research and applications.

Published: February 2025

Acute heart failure, particularly acute pulmonary edema, is a common cause of hospitalization and impacts life expectancy, especially with age. The mortality rate among patients in Southeast Asia is 13%. The severity of the condition is classified based on left ventricular ejection fraction (LVEF). Only 21.5% of patients with acute pulmonary edema have preserved ejection fraction (HFpEF). This case involves a 63-year-old male patient with acute pulmonary edema due to heart failure with preserved ejection fraction, secondary to acute hypertension and community-acquired pneumonia. Initial management followed guidelines, including symptomatic therapy and observation in the intensive care unit. After three days of treatment, the patient's condition stabilized, with improved hemodynamics and alleviation of symptoms. We want to highlight an uncommon case of HFpEF in a patient presenting with acute pulmonary edema.

Oilfield emulsions pose significant operational challenges, affecting crude oil recovery efficiency and refining processes. Conventional chemical demulsifiers, often derived from petroleum-based compounds, pose environmental and economic concerns due to their toxicity and high production costs. This study investigates the potential of plant-based alternatives—Red Onion Skin Extract (ROSE) and Orange Mesocarp Extract (OME) - as environmentally friendly, cost-effective demulsifiers. This novel approach leverages the bioactive compounds in these extracts to destabilize oil-water emulsions efficiently. Four demulsifier formulations were developed: ROSE, OME, ROSE-NaBenzoate (ROSE-NaB), and OME-NaBenzoate (OME-NaB). Fourier Transform Infrared (FTIR) spectroscopy confirmed the presence of active functional groups responsible for interfacial activity. The performance of these biobased demulsifiers was evaluated in simulated oilfield emulsions, considering the effect of key parameters such as concentration (0.2%–1.0% w/v), water content (60% and 80%), and chemical structure of the demulsifier at constant temperature of 70°C and a contact time of 180 mins. Results demonstrate that increasing demulsifier concentration significantly improves water separation efficiency. Notably, OME-NaB exhibited the highest efficiency, outperforming both the unmodified extracts and a commercial demulsifier at concentrations above 0.5% w/v. The modified formulations (ROSE-NaB and OME-NaB) showed superior destabilization efficiency due to enhanced hydrophilic-lipophilic balance (HLB), electrostatic charge neutralization, and interfacial adsorption, leading to accelerated coalescence of water droplets. Water separation performance followed the trend: OME-NaB > ROSE-NaB > Commercial Demulsifier-NaB > Commercial Demulsifier > OME > ROSE. The findings suggest that NaBenzoate-modified formulations enhance demulsification efficiency, making OME-NaB a promising candidate for industrial application. This study highlights the potential of OME-NaB as a sustainable demulsifier alternative to mitigate reliance on petroleum-based chemicals, reducing environmental impact while offering cost advantages. These insights contribute to the development of greener, efficient, and economically viable solutions for oilfield operations, aligning with global efforts toward sustainable petroleum production.
