PurposeIn a previous cross-sectional study, we reported that the sexes can be distinguished using known factors obtained from color fundus photography (CFP). However, it is not clear how sex differences in fundus parameters appear across the human lifespan. Therefore, we conducted a cohort study to investigate sex determination based on fundus parameters in elementary school students.MethodsThis prospective observational longitudinal study investigated 109 right eyes of elementary school students over 4 years (age, 8.5 to 11.5 years). From each CFP, the tessellation fundus index was calculated as red/red + green + blue (R/[R+G+B]) using the mean value of red-green-blue intensity in eight locations around the optic disc and macular region. Optic disc area, ovality ratio, papillomacular angle, and retinal vessel angles and distances were quantified according to the data in our previous report. Using 54 fundus parameters, sex was predicted by L2 regularized binomial logistic regression for each grade.ResultsThe right eyes of 53 boys and 56 girls were analyzed. The discrimination accuracy rate significantly increased with age: 56.3% at 8.5 years, 46.1% at 9.5 years, 65.5% at 10.5 years and 73.1% at 11.5 years.ConclusionsThe accuracy of sex discrimination by fundus photography improved during a 3-year cohort study of elementary school students.
STUDY OF PECTIN SUBSTANCES DURING STORAGE OF DIFFERENT VARIETIES OF TABLE GRAPE GROWING IN AZERBAIJAN
Authors: Kazimova Ilhama Huseyn , Nabiyev Akhad Ali 
Published: November 2023

This study is aimed at solving the problem of providing the population with fresh grapes not only for one or two months, but all year round. To increase the terms of consumption of this valuable raw material, the most appropriate varieties and conditions for storing grapes were determined.
The objects of study were unripe, ripe (ripe) and overripe table grape varieties widely used in the country (white varieties – Ganja table and Garaburnu, pink grape varieties – Marandi Shamakhinsky, Taifa pink, as well as red grape varieties Chernaya Asma and Pobeda). As a result of the study, it turned out that unripe and overripe red table grape varieties (Chernaya Asma and Pobeda) are richer in pectin compared to other varieties. They contain pectin substances up to 0.40–0.50 g/100 cm3. According to the content of pectin substances, pink varieties of grapes are in second place – 0.42–0.28 g/100 cm3. From a comparison of grape varieties, it is known that the amount of pectin in white table grape varieties is less than in other varieties – 0.36–0.25 g/100 cm3.
During the storage of white table grape varieties, pectin decreased within the range of 24.0–48.0%, protopectin - by 16.6–38% and for pectin this indicator decreased by 5%. This figure was 7.1–50% in pink and 23.7–45% in red table grape varieties. The decrease in pectin during storage is associated with an increase in the activity of pectin enzymes. Therefore, it is considered expedient to store table grape varieties in a refrigerator according to the first option, i.e. under conditions of RHS 3–4% CO2 and 2–3% O2, at a relative humidity of 85–92%.
And also studies have shown that for long-term and high-quality storage in a refrigerator, three options are more suitable: from white grape varieties Ganja table, from pink varieties – Marandi Shamakhinsky, and from red varieties – Black Asma.
Echocardiogram an Important Diagnostic Tool in the Intensive Care Unit - A Case of Chronic Hypoxia Induced Encephalopathy

Published: November 2023

A 68-year-old patient was admitted in our hospital with on and off fever and cough for 1 month and disorientation for 5 days. On admission, patient was hemodynamically unstable and was unable to maintain saturation on 5 litre oxygen. Provisional diagnosis of sepsis induced AKI with encephalopathy was made. MRI Brain of the patient and CSF examination were normal while bedside 2D echocardiography revealed pressure and volume overload of right ventricle which led to low cardiac output state and hence likely the maintaining factor for disorientation. These echo findings helped in managing the inotropic and vasopressor support of the patient. Inotropic and vasopressor support was weaned over a period of 3-4 days and oral digoxin was added. To conclude, echocardiography is an important bedside tool to assess the cardiac performance. Altered mental status in patients with acute exacerbation of chronic obstructive pulmonary disease remains a pressing problem in the acute medical take. Bedside 2D echocardiography done at the right time by the intensivist remains a corner stone in the effective diagnosis and management of such patients.

Published: November 2023

AbstractIn this study, we investigated the nephroprotective effects of Umbelliferone (UMB) against cisplatin‐induced acute kidney injury (AKI). C57BL/6J mice were treated with cisplatin via a single intraperitoneal injection (25 mg/kg) with or without UMB (40 mg/kg/day) by gavage. Renal function, apoptosis, oxidative stress, inflammation, and mitochondrial function were analyzed to evaluate kidney injury. In vitro, human proximal tubule epithelial cells were treated with cisplatin, with or without UMB, for 24 h. Western blotting and immunohistochemistry were performed to explore the mechanisms underlying the nephroprotective effects of UMB. Cisplatin‐induced renal dysfunction, including increases in blood urea nitrogen, serum creatinine, and renal tubular injury indices (NGAL and KIM‐1), were significantly attenuated by UMB treatment, along with renal phenotypic changes and renal tubular injury, as evidenced by improved renal histology. Moreover, NRF2 was activated by UMB pretreatment, along with the inhibition of oxidative stress and inflammatory response, as evidenced by decreased levels of antioxidant genes and inflammatory cytokines in cisplatin‐induced AKI. Our results demonstrate that UMB can protect against cisplatin‐induced nephrotoxicity, which is mediated by the NRF2 signaling pathway via antioxidant and anti‐inflammatory activities, suggesting the clinical potential of UMB for the treatment of AKI.
Beauvoir’s Myths as a Concept for Analyzing Gendered Asymmetries
Authors: Gather Claudia , Vogl Regine 
Published: November 2023

Abstract
Can the concept of myths, as developed by Simone de Beauvoir in The Second Sex, help us to better understand and sociologically examine social inequalities in heterosexual couple relationships? Beauvoir has shown how women are defined as the Other. Her conceptualization of myths plays an important role in the production of asymmetry between men and women. How can we translate these myths, to a sociological micro level to examine couple relationships? We illustrate the feasibility of this approach through the comparison of two qualitative research projects from the 1990s and 2020s with dual-earner couples in transition to retirement. We try to find out how femininity and masculinity are defined in couple relationships, how they relate to each other, and whether asymmetry is at work. What has changed over time and are women (still) defined in a subordinate and derivative way from men?
Classical Realism in World Politics. Précis to a Symposium
Authors: Kirshner Jonathan 
Published: November 2023

Abstract
This paper introduces some of the major themes of An Unwritten Future: Realism and Uncertainty in World Politics, and provides a short illustration of how the analytical apparatus elaborated there can offer fruitful insights into understanding enduring puzzles in international relations. An Unwritten Future explores, illuminates and interrogates Classical Realism, an approach to the study of world politics that is contrasted with Structural Realism and with the ‘hyper-rationalist’ perspective associated with the ‘Rationalist Explanations for War’ school of thought. It elucidates the fundamental flaws of those two highly influential paradigms, and explains why Classical Realism, with its emphasis on what Structural Realism and Hyper-rationalism forbid—content, purpose, history, and irreducible uncertainty—provides a more promising and productive point of departure for students of international relations.
Institutional Operability: Outward Rule-Following, Inward Role-Playing
Authors: Bocchiola Michele , Ceva Emanuela 
Published: November 2023

Abstract
Institutional operability refers to the normative conditions governing the exercise of power of office that makes an institution work. Because institutional action occurs by the interrelated actions of the officeholders, a focus on institutional operability requires the analysis and assessment of the officeholders’ conduct in their institutional capacity. This article distinguishes two perspectives on operability: ‘outward’ and ‘inward.’ The outward view emphasizes predefined instructions for efficient execution, focusing on rule-following to achieve institutional purposes. The inward perspective highlights role-playing and reflective engagement among officeholders to uphold an institution’s raison d’être. The inward perspective brings to the fore the relational aspect of institutional life and officeholders’ interrelated responsibility for guiding institutional action.
Thinking with Simone de Beauvoir Today
Authors: Garcia Manon 
Published: November 2023

Abstract
In the last decade, the importance of Simone de Beauvoir’s contribution to 20th-century French philosophy has been beyond debate. However, it can be tempting to read her contributions as the dated beginnings of feminist philosophy, and to believe that her work is only interesting from the perspective of the history of philosophy. To the contrary, this article claims that contemporary philosophers can and should take Beauvoirian philosophy as a source of fruitful insights on contemporary issues in political and moral philosophy by showing the limited scope of two classic critiques of Beauvoir and by defending the relevance of her work for thinking about female submission and the importance of erotic experience.

Published: November 2023

Abstract
Identifying the classification of tourism landscape resources and accurately studying their spatial pattern are of great significance to the ecological environment protection, industrial transformation, and economic growth of the Yangtze River Economic Belt. Taking Zixi County of Jiangxi Province as the research area, based on field survey and network collection, the scientific statistical classification of tourism landscape resources data in the county is conducted, and the nearest neighbor index, nuclear density analysis, average passage time, and accessibility coefficient are used to quantitatively analyze the classification, spatial agglomeration, spatial structure pattern, and spatial correlation of tourism landscape resources. The results show that: (1) Zixi County tourism landscape is complete in terms of natural resources, physical resources, and humanistic resources; (2) the spatial agglomeration analysis of tourism landscape resources in Zixi County shows an overall agglomeration distribution trend; (3) the density of tourism landscape resources varies significantly, with the spatial distribution characteristics of “large concentration at the nucleus and small dispersion at the poles”; and (4) landscape resources are well correlated, with a “strong center – weak periphery” spatial pattern. Accordingly, it is proposed that protection and development should be given equal importance, strengthening advantages, making up for shortcomings, and accelerating the development of tourism industry and economic growth, and promote the high quality and green development of the Yangtze River Economic Belt with points and lines, and help the coordinated development of the Yangtze River Economic Belt.
A Model for the World: The Austrian Constitutional Court Turns 100
Authors: Holoubek Michael , Wagrandl Ulrich 
Published: November 2023

Abstract
The design of constitutional courts usually shows a specific concern for independence from political actors and for pluralism on the bench. We argue that many institutional features of today’s constitutional courts can be traced back to the Austrian Constitutional Court (the first of its kind, which celebrated 100 years in 2020) and even further still to its predecessor, the Austrian Imperial Court of Justice of 1867. Strikingly, judicial independence is to be guaranteed against the existing judiciary as well, which is why constitutional courts often stand apart from the traditional judicial bureaucracy. Pluralism on the bench is to be ensured by specific criteria of eligibility, opening the constitutional court judgeship to a wider set of candidates (eg, attorneys, professors, civil servants), but also via institutional arrangements that make it easy for outsiders to join the court in the first place (eg, by allowing to continue one’s job or by not requiring residence at the court’s seat). Recounting the story of the Austrian model of constitutional adjudication in an unprecedented attempt to combine Austrian legal history with the structure and process of today’s constitutional courts around the world, this paper also highlights how relatively minor features of court organization contribute to the overarching goal of ensuring the independence of the court and pluralism within the court.
Die nukleare Dimension von Deutschlands F-35-Entscheidung von 2022 in historischer Perspektive
Authors: Lutsch Andreas 
Published: November 2023

Kurzfassung
Deutschlands Entscheidung von 2022, F-35 Kampfflugzeuge als Nachfolger der Tornados für Einsätze im Rahmen der nuklearen Teilhabe der NATO zu beschaffen, reflektiert einen während der Kanzlerschaft Konrad Adenauers verankerten Ansatz: Deutschland ist und bleibt ein Nichtkernwaffenstaat, produziert und kontrolliert keine Kernwaffen, aber es trägt im Rahmen der nuklearen Teilhabe der NATO zum risk and responsibility sharing unter Verbündeten teil. Deutschlands Grundsatzentscheidung zugunsten der F-35 legt zudem nahe, dass die Bundesregierung ausreichend Vertrauen in die Glaubwürdigkeit der nuklearen Schutzzusage der USA zur Abschreckung mindestens nuklearer Bedrohungen hat. Die Entscheidung von 2022 zeigt, dass fundamentale Elemente der strategischen Logik fortbestehen, die auch die nukleare Sicherheitspolitik Deutschlands während des Kalten Krieges seit Adenauer leiteten. Zu diesen Elementen gehören geostrategische Kontinuitäten, das Interesse an der transatlantischen Westbindung Deutschlands und der bedingte Verzicht auf nationale Kernwaffen. Zweitens argumentiert der Artikel, dass sich Wahrnehmungen der militärstrategischen Erfordernisse glaubwürdiger US extended nuclear deterrence bezogen auf Europa anscheinend in profunder Weise geändert haben. Demnach erscheint es als weniger anspruchsvoll als einst im Kalten Krieg, die nuklearen Schutzzusagen der USA für Europa glaubwürdig zu halten. Zudem stellt der Artikel fest, dass kein einziger Staat in der NATO – auch nicht Frankreich – in der Lage wäre, die strategische Rolle der USA in Europa einzunehmen.

Abstract
As a natural, non-toxic adsorbent, chitosan is well suited for the removal of heavy metals and antibiotics. In this study, chitosan was modified with polypropylene glycol and itaconic anhydride to improve the mechanical properties of chitosan, and the polypropylene glycol-itaconic anhydride-chitosan adsorbent was successfully prepared. The adsorbent was characterised and analysed by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis and X-ray photoelectron spectroscopy (XPS). The effects of the different conditions on the adsorption of Pb2+ and cephalexin were investigated. The Langmuir adsorption isotherm model showed that the maximum adsorption capacities of Pb2+ and cephalexin could reach 431.73 mg g−1 and 153.72 mg g−1, respectively. The possible adsorption mechanism of Pb2+ and cephalexin was discussed.

Objective. Social education is no stranger to the changes of today’s increasingly technological society. In this sense, this study aims to provide an updated overview of the the present status of the question, based on an international systematic review of the scientific literature in social education, key concepts (professionalization, identity, and professional development), and Web 2.0. Methodology. Qualitative research was conducted, based on a systematic review of international literature between 2012 and 2021. The study utilized the PRISMA-P tool as a reference, specifically by conducting a content analysis using Nvivo 12 Version Release 1.5 software. Among other strategies, the study conducted text searches and employed hierarchical maps and coding matrices. The final selection contained 22 articles that were reviewed and categorized from an inductive-deductive approach. Results. Social media have a notorious impact on fundamental aspects of social education such as professionalization, identity, and professional development. The study highlights the need for competence development of social educators for an ethical performance of their work in the virtual space. Conclusion. In today’s technologized society, the use of social media continues its exponential rise, and the profession of social education must also seek its place in the virtual environment, recognizing that the profession has to respond to a society in which the Internet is a communication space. In this sense, a wider definition of digital competencies in social education is advocated.
El proyecto “Eu participio”. Una estrategia local de Educación para la Ciudadanía
Authors: Silva Fraga Nuno , Correira Cristina 
Published: November 2023

Este trabajo pretende describir los principales supuestos pedagógicos subyacentes en la realización de un proyecto piloto basado en la participación por parte de los niños(as) y sus consecuencias. Se enmarca en dos movimientos encargados de inspirar los procesos que promueven y articulan la participación ciudadana: “Ciudades Educadoras” y “Ciudades Amigas de los Niños”. El equipo que participo creyó conveniente tener como punto de partida la “Convención de los Derechos del Niño”. El proyecto tuvo lugar en la Escuela de Primaria de Batudes (Palmela, 2011/2012). Los objetivos principales son: promover espacios donde los niños pueden experimentar los valores intrínsecos de la democracia participativa, desarrollar la creatividad para construir relaciones sociales e intervenciones comunitarias y acercar a los niños a los funcionamientos de las instituciones locales. Como una de las conclusiones de este trabajo, debe destacarse que los objetivos han sido alcanzados además de conseguir que los profesores ejercieran una reflexión crítica sobre su práctica educativa. Se pudo comprobar y hacer evidente que la capacidad de trabajo sobre el plan de estudios desde una perspectiva participativa, mejoro los procesos de enseñanza aprendizaje en los estudiantes a la vez que estimulo la motivación en todos los sentidos.
