Abstract

Purpose
This study aims to evaluate the association between psychiatric disorders and diabetic ketoacidosis (DKA) in patients with type 1 diabetes (T1D) treated at a tertiary care hospital.

Methods
A propensity score-matched case-control study was conducted, comprising a total sample of 194 participants (97 DKA cases and 97 controls without DKA). Comprehensive data were collected on clinical, anthropometric, and socioeconomic characteristics, and psychiatric disorders were classified according to international standards.

Results
The mean age of the participants was 47.4 ± 17.7 years, with 55.6% being female. Psychiatric disorders were identified in 16.5% of the study population. The prevalence of psychiatric disorders was significantly higher in DKA cases compared to controls (24.7% vs. 7.2%, p < 0.001). Conditional logistic regression models revealed that the association between psychiatric disorders and DKA was not independent of HbA1c levels. Additionally, in HbA1c-stratified analyses, patients with psychiatric disorders developed DKA at lower HbA1c levels compared to controls.

Conclusion
Psychiatric disorders significantly increase the risk of DKA in adults with T1D, particularly among those with less elevated HbA1c levels. These findings highlight the critical importance of addresing psychiatric comorbidities in the management of T1D, given the severe implications and significant healthcare resource utilization associated with DKA.
Eltern und Familien als Adressat_innen von Sozialer Arbeit in Bildungsinstitutionen

Zusammenfassung
Während die Schulsozialarbeit mittlerweile nahezu flächendeckend als etabliertes Angebot im Leistungsspektrum der Kinder- und Jugendhilfe gilt, stellt die Kita-Sozialarbeit ein Beratungs- und Unterstützungsarrangements dar, das erst in den letzten Jahren an Bedeutung gewinnt. Schulsozialarbeit wird in Hinblick auf die konzeptionelle Ausformung der Kita-Sozialarbeit vielfach als fachlicher Bezugspunkt herangezogen, ohne dass jedoch eine systematische Begründung stattfindet. In dem vorliegenden Schwerpunkt wird auf beide Arbeitsfelder eingegangen und dabei insbesondere die Familienorientierung aufgegriffen, die sich für beide Bereiche beobachten lässt. Anzunehmen ist, dass sich eine neue Aufmerksamkeit in Politik, Wissenschaft und Fachpraxis für Familie und Elternschaft insgesamt gerade auch für Schulsozialarbeit und Kita-Sozialarbeit nachzeichnen lässt. Anliegen des Schwerpunkts ist es, diese Familienorientierung für beide Felder näher zu untersuchen und in ihren Konsequenzen zu reflektieren.
NGO’s religious affiliation and donation intent: the role of missionary alarm and manipulative intent
Authors: Sevriugin Sergei , Sheehan Ben 
Published: January 2025

Abstract
An individual’s religious orientation is known to predict their donantion intent. But does an aid organizations religious affiliation impact donations? This research investigates the relationship between an NGO’s religious affiliation and donation intent. Missionary alarm (concerns about proselytization) and manipulative intent are tested as accounts for the negative effects of religious affiliation on donation intent. Two experiments compare missionary alarm, manipulative intent and donation intent across three types of NGO: (a) non-faith-based organizations (N-FBO), (b) single-faith-based organizations (one organization representing a single faith; S-FBO), and (c) multi-faith-based organizations (a single organization, representing multiple faiths; M-FBO). The results suggests that religious affiliation reduces donation intent (N-FBO > S-FBO). However, presenting an organization as multi-faith may counteract the negative effects of religious affiliation (M-FBO = N-FBO > S-FBO). The results appear to hold in different charitable contexts (natural disaster aid in Southeast Asia and education aid in Africa). Novel findings include the deleterious effects of missionary alarm, and the positive effects of presenting an NGO as multi- vs. single-faith. Practitioners representing S-FBOs are advised to collaborate with other religions in order to enhance their appeal.

Abstract
Concerns about the mental health of college students have been increasing over the last several decades. The COVID-19 pandemic only served to put more attention on this problem. Prior to the pandemic, minority students bore a heavier burden of mental disorder symptoms, but it is unclear if this racial difference persisted during the COVID-19 pandemic and if the resilience of students to this crisis varies by race. This study investigates race-specific trends in college students’ mental health, using four repeated cross-sectional surveys collected yearly between November 2019 and November 2022 from students in a Midwestern state university in the United States. We found that racial minority students had a higher level of symptoms before the pandemic. However, they did not experience a significant elevation during the pandemic. On the other hand, White students reacted more dramatically to the initial shock of the pandemic in 2020. They recovered in 2021 but experienced another elevation in mental health symptoms in 2022. Our study added to the minority mental health paradox literature that racial minority students were more resilient to the impact of the pandemic than White students. Programs to enhance resilience for all students are recommended.

Abstract
In this study, erosion tests were conducted to evaluate the abrasivity of organic particles to produce wear on a material surface with higher hardness. The novelty of this research work was that pistachio shells, which are usually waste that ends up in the garbage, were collected, ground and sieved to obtain a sufficient quantity of pistachio angular particles to be used productively to perform these wear tests. Additionally, sea shells were thought of as an alternative to organic abrasives, and these were ground, sieved and prepared to be able to carry out the testing. The erosion tests conducted based on ASTM G76 and SEM images showed typical wear mechanisms such as high plastic deformation (material displacement) characterized by micro-cutting and micro-ploughing actions, grooves with lifted lips in the edges as pistachio grits employed to run the tests. On the other hand, a conventional abrasive as glass bead particles caused huge craters, broken and smeared flakes, ploughing and circumferential cracks on the AISI 420 stainless steel surfaces. The highest erosion rates were reached as glass beads were employed to run the erosion tests. AFM technique was used to show the surface variations after the erosive impacts. The eroded scars produced by pistachio and sea shells allowed us to remark that the proposed organic abrasives could be used for polishing, surface finishing and cleaning applications on surfaces of mechanical elements that are dirty or rusty. This was due to their low density, which led to low and very superficial erosion damage.
Cutting-edge insights into liver fibrosis: advanced therapeutic strategies and future perspectives using engineered mesenchymal stem cell-derived exosomes
Authors: Didamoony Manar A. , Soubh Ayman A. , Ahmed Lamiaa A. 
Published: January 2025

Abstract
Liver fibrosis is still a serious health concern worldwide, and there is increasing interest in mesenchymal stem cells (MSCs) with tremendous potential for treating this disease because of their regenerative and paracrine effects. Recently, many researches have focused on using the released exosomes (EXOs) from stem cells to treat liver fibrosis rather than using parent stem cells themselves. MSC-derived EXOs (MSC-EXOs) have demonstrated favourable outcomes similar to cell treatment in terms of regenerative, immunomodulatory, anti-apoptotic, anti-oxidant, anti-necroptotic, anti-inflammatory and anti-fibrotic actions in several models of liver fibrosis. EXOs are superior to their parent cells in several terms, including lower immunogenicity and risk of tumour formation. However, maintaining the stability and efficacy of EXOs after in vivo transplantation remains a major challenge in their clinical applicability. Therefore, several strategies have been applied in EXOs engineering, such as parental cell modification or modifying EXOs directly to achieve optimum performance of EXOs in treating liver fibrosis. Herein, we discuss the underlying mechanisms of liver fibrosis with an overview of the available therapies, among them EXOs. We also summarise the recent developments in improving the effectiveness of EXOs with the advantages and limitations of these approaches in terms of the upcoming clinical applications.

Published: January 2025

Abstract
Black liquor from paper and pulp mills is an underutilized waste resource. Black liquor can be valorized due to its useful chemical fractions and water component that can be employed for the pretreatment and biochemical conversion of starchy potato waste (SPW) into bioethanol. Hence, in this study, the simultaneous co-valorization, detoxification, and fermentation of SPW and black liquor (without the addition of freshwater and chemicals) were optimized for bioethanol production. The scanning electron microscopy (SEM) and the Fourier-transform infrared (FTIR) clearly confirmed the distortion of SPW inherent structure for the recovery of useful carbohydrates. A significant reduction in process inhibitors (furfural = 1.26-fold, hydroxymethylfurfural (HMF) = 5.68-fold, and phenols = 1.03-fold) was observed with CuO NP inclusion. The response surface methodology (RSM) model of the bioethanol production showed a high coefficient of determination (R

) value of 0.98. The optimized process with CuO NP inclusion displayed a biomass and bioethanol concentrations of 2.12 g/L and 21.37 g/L corresponding to 1.74- and 1.68-fold improvement over the control respectively. In addition, the kinetic data showed that the incorporation of CuO nanoparticle (NP) significantly improved (1.86-fold) the potential maximum bioethanol concentration (Pm) (20.21 g/L) compared to the control experiment (10.86 g/L). The study demonstrates a 100% freshwater conservation approach for improved sugar recovery, remarkable inhibitor removal, and bioethanol production from pretreated SPW towards reduced biofuel production cost, waste management, and green environment sustainability.
Increasing power generation and energy efficiency with modified anodes in algae-supported microbial fuel cells
Authors: Altın Necla , Uyar Başar 
Published: January 2025

Abstract
In this study, an algae-assisted microbial fuel cell (MFC) was developed to both treat horse manure wastewater and generate electricity. Carbon felt (CF) and graphite felt (GF) electrodes were modified with carbon nanotube (MWCNT) and nitric acid (HNO₃) to prepare different anodes and their effects on MFC performance were evaluated. The power density of 59 mW/m2 obtained with the CF-HNO₃ anode showed the highest value among all tested systems and was found to be 2.45 and 2.13 times higher than unmodified CF and GF anodes, respectively. Moreover, a 17% higher performance was achieved compared to the GF-HNO₃ anode. The higher performance of CF-HNO₃ compared to GF-HNO₃ can be attributed to the higher surface area of the carbon felt, improved proton conduction, and increased electrochemical activity after treatment with nitric acid. The modified CF-MWCNT and GF-MWCNT anodes produced power densities of 55 mW/m2 and 45 mW/m2, respectively. The Coulombic efficiency (CE) values obtained were in line with these results. The results reveal that nitric acid modification significantly increases the power output of MFCs by providing accelerated electron transfer on biofilms. This simple and effective method offers a new approach to develop low-cost and high-performance electrode materials for MFCs. Moreover, the analysis of algal biomass from the cathode chamber is in line with the existing literature and makes an important contribution towards sustainable energy solutions. The study stands out as a promising step towards the scalability and commercialization of MFCs. Furthermore, the findings can contribute to economic feasibility through low-cost modification techniques and support environmental sustainability. The findings contribute to economic feasibility and support environmental sustainability through low-cost modification techniques. Future studies can support the wider adoption of MFCs for industrial applications by investigating the effects of these modifications on long-term performance and compatibility with different wastewater types. This could accelerate the transition to sustainable energy solutions by promoting the wider use of MFCs in power generation and wastewater treatment.

Empirical vitalism: observing an organism’s formative power within an active and co-constitutive relation between subject and object
Authors: Hueck Christoph J. 
Published: January 2025

Abstract
This article proposes an empirical approach to understanding the life of an organism that overcomes reductionist and dualist conceptions. The approach is based on Immanuel Kant’s analysis of the cognitive conditions required for the recognition of an organism: the concept of teleology and the assumption of a formative power of self-generation. It is analyzed how these two criteria are applied in the cognition of a developing organism. Using the example of a developmental series of a plant leaf, an active and relational process between observer and developing organism is shown, within which the teleology and self-generating power of the organism can be empirically observed through the mental faculties of understanding and will. Furthermore, it is emphasized that, according to Kant, even physical objects are not readily given, but are actively constituted through the unification of sense perceptions with concepts. This Kantian mode of objectification facilitates cognition of the physical properties of an organism. It can be supplemented with a participatory and co-constitutive mode of realization, in which the teleologically organizing and self-generating power of the organism can become an object of empirical research. It is argued that the participatory mode also facilitates an expanded conception of nature that allows for the existence of living beings within it. Finally, an analogy to Goethe’s approach to the living organism is highlighted. In summary, it is stated that it is possible to understand life by consciously participating in it.
Investigation of the Dynamical Analysis, Stability, and Bifurcation for a Connected Damped Oscillator with a Piezoelectric Harvester
Authors: Amer T. S. , Abdelhfeez S. A. , Elbaz Rewan F. , Abohamer M. K. 
Published: January 2025

Abstract

Purpose
The present work investigates and analyzes the mathematical modeling of a dynamical system attached to a piezoelectric device. It is well-established that piezoelectric transducers are effective energy harvesting devices commonly utilized in practical applications with mechanical systems. The structure of the dynamical model contains a damped Duffing oscillator acting as the major component, which is connected to an un-stretched pendulum and at the same time, to the piezoelectric harvester.

Method
Lagrange's equations are employed to deduce the governing equations of motion (EOM) based on the overall generalized coordinates characterizing the system. This model has been solved analytically using a perturbation technique known multiple-scales (MS) up to the third approximation. This indicates a level of complexity and detail in the model’s analysis. Moreover, the obtained solutions are compared with the numerical ones for more transparency and to highlight the accuracy of the approximate solutions.

Results
Detailed graphical figures have been executed to study the nonlinear stability analysis of the equations of modulation. Phase portrait diagrams, bifurcation ones, and spectrums of Lyapunov are exhibited to illustrate various types of systems’ behavior, complemented by Poincaré maps for further insight. Additionally, the varied ranges of the stabilities are explored and discussed.

Applications
The mechanical vibrations are converted to electricity due to the existence of the piezoelectric transducer that is connected to the dynamic model, which has wide uses and applications like crystal oscillators, medical ultrasound applications, gas igniters, and displacement transducers.

Authors: Xu Ruiyu , Song Zheren , Wu Jianguo , Wang Chao , Zhou Shiyu 
Published: January 2025

Abstract
Recent advances in deep learning have led to the creation of various methods for change-point detection (CPD). These methods enhance the ability of CPD techniques to handle complex, high-dimensional data, making them more adaptable and less dependent on strict assumptions about data distributions. CPD methods have also demonstrated high accuracy and have been applied across various fields, including manufacturing, healthcare, activity monitoring, finance, and environmental monitoring. This review provides an overview of how these methods are applied, the data sets they use, and how their performance is evaluated. It also organizes techniques into supervised and unsupervised categories, citing key studies. Finally, we explore ongoing challenges and suggest directions for future research to improve interpretability, generalizability, and real-world implementation.
An estimation method for the fuel burn and other performance characteristics of civil transport aircraft; part 3 full flight profile when the trajectory is specified
Authors: Poll D.I.A. , Schumann U. 
Published: January 2025

Abstract
If an aircraft’s initial mass, the variation of true airspeed, true rate of climb, wind speed and wind direction with time and the relationship between barometric altitude and local temperature are known, the performance along the entire flight path can be determined. Previously published work has provided the building blocks for a simple, fast, open-source and transparent method to estimate the instantaneous fuel flow rate and the engine overall efficiency, plus several other performance characteristics for turbofan powered, civil transport aircraft. The flight phases of primary interest are the climb, cruise, descent and holding, when the flaps and undercarriage are fully retracted and the engine is providing significant, positive thrust. However, for completeness, an approximate relation is provided for the engine’s ‘flight idle’ condition, together with simple estimates for fuel use during take-off and landing, plus a factor to allow for in-service deterioration. Detailed consideration is also given to the operating limits and relations are developed for the estimation of their location in Mach number and flight level space. To apply the method, a series of characteristic coefficients and constants must be known. Estimates for these quantities have been progressively improved and extended over time. Initially, results were published for 53 aircraft types and variants. The data base has now been extended to 67 entries and this is given in tabular form. Finally, to demonstrate the method’s accuracy, estimates of fuel flow rate are compared with flight data recorder values for 20 complete flights of six different aircraft types.
How leaders perceive security dangers: The neglected dimension of unfolding experience
Authors: Oren Eitan 
Published: January 2025

Abstract
Leaders play a central role in world politics, and threat perception is a crucial element in the study and practice of International Relations (IR). Yet existing accounts of how leaders perceive threats are inadequate, drawing on an incomplete notion of leaders as (ir)rational information processors that pays no attention to the leader’s experience of danger as it unfolds in time and how such experience is structured. By integrating a framework developed by linguist Ray Jackendoff to describe the experience of language with the study of danger in International Relations, and by employing an interpretive textual analysis technique to danger descriptions made by world leaders embedded in different historical and cultural settings constructing different security dangers, I develop and illustrate the ‘danger framework’. In describing the unique features with which leaders experience security dangers, the danger framework theorises the qualia of danger experience and how it is organised into the conscious field of leaders. In doing so, the paper makes progress on three problems for existing accounts of threat perception in IR, illuminates important research puzzles, and provides the literature on experience and Ontological Security Studies (OSS) with micro-foundations.
