P138 Modelling and Simulation of Pressure Re-reflections at the Aortic Valve Using Difference Equations
Authors: Hametner Bernhard , Kastinger Hannah , Wassertheurer Siegfried 
Published: February 2024

Abstract
Introduction
The concept of re-reflections of blood pressure waves at the heart has been neglected in most models and is only poorly understood so far. Therefore, the aim of this work was to develop a simple mathematical model which is capable to represent the effects of wave travel, wave reflection as well as re-reflection at the aortic valve.

Methods
A mathematical model based on difference equations has been developed. The equation for the backward travelling pressure waves includes several terms, where the forward pressure is multiplied by a specific reflection coefficient and is delayed by a specific period of time corresponding to the location of the reflection site and the stiffness of the travel path. The equation for the forward travelling waves includes an input pressure coming from the heart as well as the backward pressure multiplied by a time-dependent re-reflection coefficient.

Results
After identifying suitable distal reflection parameters to get a realistic pressure wave, sensitivity analyses on the time-dependent re-reflection coefficient were performed. Exemplarily, the re-reflection coefficient was held at the level of 1 during diastole (aortic valve closed), while it was varied from 0.6 to 0.9 during systole, see Figure 1.

Conclusion
With a simple difference equation model, aortic pressure waves can be simulated adequately. The choice of the re-reflection coefficient at the aortic valve strongly influences the results, both regarding pressure level and wave shape. This indicates that re-reflections should be incorporated into models of wave transmission as well as in methods of arterial pulse wave analysis.

Abstract
Purpose
Referral to surgery in thoracic aortic aneurysms (TAA) is based on maximal diameter (Dmax) measured from imaging, which is known to have a high diagnosis failure rate. In addition to geometry, 4D flow MRI provides a comprehensive time-resolved flow imaging. Thus, our aim was to evaluate the ability of 4D flow MRI-derived quantitative flow indices to characterize TAA.

Methods
We studied 20 patients with TAA and tricuspid valve (TAVd, Dmax = 43 ± 5 mm, Age = 66 ± 14 years) and 56 healthy controls (YC: 30 subjects, Age = 36 ± 9 years ≤50 years, OC: 26 subjects, Age = 65 ± 9 years > 50 years). All underwent 4D flow MRI. After aortic segmentation, ascending aorta (AA) backward flow volume (VBF) was calculated in addition to maximal velocity jet angle and eccentricity (Ecc). Receiver operating characteristic analysis was performed to assess the ability of flow indices to characterize AA = dilation.

Results
While AA Dmax was 1.4-fold higher in TAVd than OC, VBF increased by 6.5 folds and Ecc and Angle varied by 1.3 to 1.7 folds between the two groups. Moreover, VBF changed by 12.7 folds between the aneurysmal AA as compared to TAVd descending aorta. Finally, VBF increased consistently with age in all controls and was able to detect AA dilation with a 0.98 accuracy.

Conclusion
AA backward flow quantified from 4D flow MRI outperformed the previously described indices such as flow eccentricity and angle in the characterization of thoracic aortic aneurysms.

Background: Adolescence is a relatively fast period of physical change experienced by adolescents when puberty is marked by the first menstruation (menarche). Menstruation and menstrual habits continue to encounter numerous social, cultural, and religious barriers, which make it extremely difficult to maintain good hygiene during the menstrual cycle. Objective: Analyzing menstruation practices and the prevalence of dysmenorrhea in adolescent female is the goal of this study. Method: The cross-sectional investigation was carried out in Sukoharjo and Surakarta. The research was carried out between December 2023 and January 2024. Adolescent female samples had reached menarche. WaLIDD score is an instrument used to measure dysmenorrhea. Results: The results of this study show as many as 71.7% of Menarche adolescent girls at the age of 12-14 years. As many as 44.4% of respondents said dysmenorrhea almost always interfered with work activities. Data also shows that nearly 100 % of respondents wash their hands before and after replacing menstrual materials. The majority of them wash their genitals using soap (79.1%) and replace pads (>3 times) 72.5%. Conclusion: Most respondents practice good menstrual hygiene, characterized by frequent washing of hands and genitals. Adolescent females who are knowledgeable about their periods can make hygienic and safe menstrual habits.

sangue e il corallo

Nata fin dall’origine come resoconto della relazione esistenziale tra il soggetto e il mondo, la poesia di Anedda ha accentuato nell’ultimo periodo la dimensione ‘ecologica’, ovvero la costruzione di un sistema in cui elementi naturali, piante, oggetti, esseri umani, animali, regno minerale e inorganico, trovano nella pagina una loro misura di scambio e trasformazione continua. Il contributo focalizza la costellazione testuale ibrida degli ultimi anni (Historiae 2018, Geografie 2021, Poesia come ossigeno 2021, Le piante di Darwin e i topi di Leopardi 2022) rilevando caratteri formali e strutture enunciative proprie di una visione ecologica della storia e della poesia stessa. In particolare, si osservano la pluralizzazione e l’ibridazione delle scritture, le scelte linguistiche e retoriche e la loro teorizzazione in termini di sostenibilità, il meccanismo associativo dell’interferenza che traduce il tempo in spazio, laddove nei segni del visibile si può cogliere l’incessante processo di mutamento e metamorfosi che caratterizza la storia delle specie sul pianeta.

Blood and Coral. The Ecological Writing of Antonella Anedda
Although initially conceived as an account of the existential relationship between the subject and the world, Anedda’s poetry has recently accentuated the 'ecological' dimension, that is, the construction of a system in which natural elements, plants, objects, human beings, animals, mineral kingdom, and inorganic engage in continuous exchanges and transformations. The contribution focuses on the hybrid textual constellation of recent years (Historiae 2018, Geographies 2021, Poetry as Oxygen 2021, Darwin’s Plants and Leopards' Mice 2022) acknowledging formal characters and enunciative structures proper to an ecological vision of history and of poetry itself. Particular attention is paid to the phenomenon of pluralization and hybridization of writing, linguistic and rhetorical choices as well as their theorization in terms of sustainability, and the associative mechanism of interference translating time into space, where one can grasp the incessant process of change and metamorphosis that characterizes the history of the species on the planet.

Societal Consequences of Modern Hybrid Warfare in Political-Economic and Institutional Discourse
Authors: Grytsenko A. , Burlai T. , Borzenko O. 
Published: February 2024

Object: to reveal the features of the societal approach to the study of the modern hybrid war consequences, a striking example of which is the Russian invasion of Ukraine in February 2022, based on the study of the reflection of changes in social reality in the unity of political-economic, sociological and institutional discourses.
Methods: ascension from the abstract to the concrete; dialectical; logical-historical; fractal method of institutional economics; structural-functional and world-systems analysis. Findings: the current Russian-Ukrainian war has clear signs of a modern hybrid war generated by the globallocal hybrid system “peace — war” and combines a whole complex of means: military-political, economic, cybernetic, etc. On the basis of the combination of political-economic, sociological (in a broad sense) and institutional discourses, it is substantiated that the main components of the “peace — war” hybrid system from the point of view of the societal relations transformation are: armed-military, financial-economic and informational-spiritual components. It is shown that through the channels of world perception and positioning they lead to changes in behavioural patterns, through which the response of the actors is carried out, changing the already changing reality. This leads to the closure of changes in social reality through the behaviour of subjects on themselves, gives integrity and acceleration to societal processes.
Conclusions: the feature of the societal approach is revealed only on the basis of a combination of politicaleconomic (which opens up the possibility of tracing chains of cause-and-effect relationships), sociological in a broad sense (allowing you to look at society as a whole in the unity of its components and measure them) and institutional (giving the key to understanding changes in rules and norms of social life) approaches. This feature consists, in contrast to the social approach (fixing the structural and functional structure of social reality), in the study of social transformations, which actualizes the problems of interaction and reflexivity of social structures and functions. In the conditions of martial law, the role of the trust institution as a defining and integral construct of the socio-economic system’s institutional architectonics, embodied both in trust in the state and power structures, and in trust in new institutions born of hybrid war. The societal approach opens up the possibility of a new look at the problems of the Ukrainian post-war reconstruction, taking into account both the objective logic of social transformations and the need to increase social activity in institutional transformations that involve the formation of a new development model in the European socio-economic space.

<p>Environmental risks are a cumbersome financial burden to any organization. This thesis aims to establish best practices for integrating environmental risks into the ERM holistic approach to creating value for Canadian organizations as strategic speculative risk. Culture, leadership, risk appetite, integrated risk framework and value are five pillars that may influence the integration process. </p>
<p>The research involved four phases, including a review of the literature methodologies to determine the most appropriate approach to conduct the thesis, a scoping review of 54 academic articles, a content analysis of 20 sustainability reports for leading Canadian organizations. Finally, merging the results of both literature analyses generated a best practice list, which was analyzed against the research's five pillars. The thesis concluded the organizational culture supremacy on the overall integration process and reframing the environmental risks as a rewarded risk embraced with the ERM system, thus creating stakeholder value and enhancing business continuity.</p>
Impact of zinc and copper on antibiotic resistance and conjugative plasmid transfer in bacteria isolated from wastewater treatment plants
Authors: Ahmed Saher Maham 
Published: February 2024

<p>The rapid emergence of antibiotic resistance is leading to a global public health crisis. The purpose of this study was to examine zinc and copper, two environmentally and clinically relevant heavy metals that have shown potential at promoting resistance, as influencers on antibiotic resistance profiles and conjugative plasmid transfer in bacteria isolated from wastewater treatment plants (WWTPs). A total of 47 bacterial cultures isolated from WWTPs were examined to determine the effect of zinc and copper on their antibiotic resistance profiles and whether the metals had an impact on the transfer of plasmids carrying antibiotic resistance genes. It was found that only a few isolates were affected by zinc or copper. Sub-inhibitory levels of copper were found to have no significant effect on plasmid transfer between two environmental strains of Escherichia coli (E.coli). It is important to control the spread of antibiotic resistance and reinstate efficacy of antibiotics. </p>
