Du châtiment à la honte
Authors: Farina-Schroll Andreas
Published: December 2024

L’eschatologie du Gorgias a laissé plus d’un lecteur de Platon perplexe, un constat que l’on peut particulièrement observer dans le traitement par les interprètes du rôle spécifique du châtiment réservé aux âmes injustes dans l’Hadès. Dans cette étude, nous souhaitons montrer que la fonction du châtiment dans l’eschatologie du Gorgias est d’offrir une métaphore des effets de la réfutation sur l’âme. Pour ce faire, nous montrerons que le châtiment est lui-même modelé en fonction d’une analogie médicale qui structure le dialogue dans son ensemble. Après avoir montré que Socrate introduit cette analogie au sein du mythe à l’aide du critère de la nudité, nous examinerons la description du châtiment lui-même. Enfin, si nous pouvons affirmer que le châtiment reflète la réfutation, c’est parce que la douleur qu’il provoque est analogue à la honte éprouvée lorsqu’une personne disposant des mauvaises croyances est réfutée.
La place du végétal dans une pensée du vivant
Authors: Dheur Sonia , Saupe Sven J.
Published: December 2024

Il est fréquent que les plantes soient décrites comme inférieures et antérieures aux formes de vie animales. C’est notamment cette position que leur assigne l’échelle des êtres. Dans cette position, le végétal a néanmoins pu servir de point de comparaison pour penser la place de l’animal mais aussi la vie comme phénomène unitaire. Contre cette dévalorisation du végétal dans une certaine tradition, une tendance actuelle vise à une prise en compte pleine de ses spécificités. Il s’agirait maintenant de se demander ce que l’animal et l’homme ont de commun avec le végétal, au sens des points communs mais aussi de la mise en commun sous forme d’interactions et d’échanges. Nous nous proposons d’aborder cette question depuis la perspective de la biologie contemporaine en nous attachant particulièrement aux catégories fonctionnelles qui définissent traditionnellement l’âme végétative, la nutrition et la reproduction. Cette perspective est de fait une perspective évolutionniste. Elle nous permettra d’une part d’insister sur la relative parenté évolutive du végétal et de l’animal au regard de la diversité globale du vivant et aussi de proposer que la spécificité du monde végétal tienne peut-être au fait que s’y exprime plus clairement qu’ailleurs, pour tout un chacun, l’inscription co-évolutive de tous les vivants en des réseaux interspécifiques complexes.
Définir la communication des plantes : un échange de signes ?

Published: December 2024

Cet article examine les problèmes que pose la biologie végétale aux définitions de la communication. Après avoir introduit les enjeux principaux de la problématique et discuté les définitions générales de la communication, l’approche éthologique de la communication est exposée. Des exemples des moyens et des finalités des échanges d’information, entre plantes sont ensuite passés en revue et analysés selon les critères des définitions. Enfin, les raisons épistémologiques expliquant les difficultés à appliquer la communication aux plantes sont discutées, notamment dans une perspective sémiotique.
Un professionnalisme organisationnel dominant chez les travailleuses sociales et les conseillères à l’emploi
Authors: Boeglin-Henky Mathilde
Published: December 2024

À partir d’une enquête ethnographique, cette contribution s’intéresse aux pratiques professionnelles des conseillères à l’emploi et des travailleuses sociales confrontées aux outils de gestion informatiques dans le cadre de la dématérialisation des services publics de l’emploi. L’étude comparative entre groupes professionnels montre que le professionnalisme organisationnel, qui se caractérise par un discours de contrôle des procédures émises par l’organisation et la valorisation de pratiques de travail normalisées édictées par le management, est dominant à Pôle emploi et dans les structures d’accompagnement des allocataires du revenu de solidarité active (RSA). Des conseillères à l’emploi et des travailleuses sociales en situation de déclassement social ou professionnel adhèrent à la réforme pour évoluer professionnellement, avec le soutien de leur encadrement de proximité. Les travailleuses qui se situent du côté du professionnalisme de métier résistent à la réforme pour maintenir leur autonomie au travail mais sont disqualifiées par leurs supérieures hiérarchiques au moment des promotions et de l’attribution des primes.

Authors: Rasheed Muhammad Qasim , Rauf Muhammad , Akhtar Muhammad Saeed
Published: December 2024

In this study beads like nanoparticles of manganese oxide with different doping of iron concentrations from 2% to 10% were deposited on ultrasonically cleaned glass substrate by chemical bath deposition technique. Different analytical techniques including XRD, SEM, DRS and VSM were utilized to analyze the structure, morphology, optical and magnetic properties. XRD analysis confirms the crystallite size of Fe-MnO2 were between 13.70 nm to 46.46 nm, morphological examination indicated that Fe-MnO2 have cubic and beads-like structures. SEM have revealed the average grain size of 613.3 nm and non-uniform deposition of thin film, DRS analysis confirms that pure MnO has band gap energy 2.90 eV and is decreased with increasing concentration of iron i.e shifted towards lower band gap energy semiconductor materials, VSM reveals that magnetization increases with increase in iron concentration. The best properties were obtained at 6% iron doping because, with further increase in doping concentration, the structure started to distort.
Adhesion of Aluminum Alloy to Tip of Nozzle Plate of Vertical Type High Speed Twin Roll Caster
Authors: Haga Toshio , Ochi Hiizu , Fuse Hiroshi , Watari Hisaki , Nishida Shinichi
Published: December 2024

In a vertical type high-speed twin-roll caster, the adhesion of solidified aluminum alloy to the nozzle (ASAN) makes problems with the quality of the strip surface. The effects of the Si content of Al–Si alloys and the casting conditions on the ASAN were investigated. Alloys with Si contents of 0%, 0.5%, 1%, 2%, 3%, 6% and 10% were considered. The ASAN was high for Si contents of 0.5%, 1%, and 2%. This demonstrates that there is a relationship between the quasi-solid state and the ASAN. As the roll speed and molten metal temperature increased and solidification length decreased, the ASAN decreased. On the basis of these results, the stagnation of molten metal near the nozzle plate was investigated. A gap of 5 mm was introduced between the nozzle plate and the roll surface to eliminate the stagnation of molten metal, resulting in reduction of the ASAN.

Published: December 2024

Herein, we have synthesized polypyrrole grafted graphene oxide (GO-g-PPy) nanohybrids by a free radical emulsion graft polymerization method. GO was used as the substrate for pyrrole grafting. The parameters of the graft polymerization reaction were optimized. The optimum concentrations of surfactant, monomer and initiator were 0.25 wt. %, 3 vol.%, and 7 wt.%, respectively. The maximum grafting percentage was 989.6% at these optimal reaction parameters. The formation of the grafted nanohybrids was confirmed by Fourier transform infrared spectroscopy (FTIR) and thermal stability studies were carried out by thermogravimetric analysis (TGA). GO-g-PPy naohybrids can be used as functional additives or conductive materials for EMI shielding applications.

Authors: Yadav Rajnee , Yadav Akshita , Lahariya Vikas
Published: December 2024

In this article, excitation independent and dependent fluorescence properties of surface functionalized carbon dots were studied. The samples were synthesized using a biomass derived Indian gooseberry as carbon precursor via microwave irradiation technique. Concentrated phosphonic acid is utilized as a surface passivator for carbon dots. The formation of spherical carbon dots in the size range of 6 to 12 nm was shown by transmission electron microscopy images. Raman and Fourier transform IR spectroscopies suggest the creation of highly disordered sp3carbon atoms including presence of surface functional groups and interaction of phosphorus with surface of carbon core. From the UV-visible absorption study, absorbance bands at 231 nm and 283 nm attributed to π-π* molecular transitions from carbon core are found. From the photoluminescence measurements, both excitation independent and excitation dependent tunable fluorescence is obtained from ultraviolet to visible (yellow) region of light respectively. The involvement of carbon core electronic states and surface modifier states are responsible for the origin of luminescence and their distinguished nature. The mechanism is discussed and emitted colour are confirmed by CIE plot. The relative quantum yield of the P-functionalized carbon dots is found to be 18.9% with reference to quinine sulfate. The fluorescence in ultra-violet and visible regions is applicable for bioimaging and potential antimicrobial activities.

Published: December 2024

Undoped and Ni-Eu co-doped ZnO thin films were successfully fabricated via spray pyrolysis at 400°C. The impact of co-doping on the structural, morphological, electrical, and optical properties of the thin films was thoroughly investigated. X-ray diffraction (XRD) analysis confirmed the absence of secondary phases and verified the successful incorporation of dopant ions into the ZnO lattice. Morphological examination revealed enhanced crystallization and a more uniform surface following the incorporation of nickel. Spectral studies in the UV-Vis region were conducted to determine the optical band gap of the synthesized ZnO films, indicating a slight decrease in bandgap values and volume and surface energy losses (VELF and SELF) with increasing Ni doping concentration. Photoluminescence spectra exhibited emission peaks in the UV region around 415 nm and broad visible emissions spanning 450-650 nm for all samples. Electrical characterization using Hall Effect measurements confirmed n-type electrical conductivity in all prepared films, as evidenced by the observed negative Hall coefficients. The co-doped ZnO thin films, particularly those incorporating Ni-Eu, show promise for applications in electronic and optoelectronic devices. Additionally, we investigated the photodegradation of green malachite under a UV lamp. Remarkably, the results demonstrated degradation rates of 93% within 2 hours, showcasing promising potential for practical applications.

Published: December 2024

Objective:

To describe the various options available for preserving female and/or male fertility, taking into account both social and medical aspects, and to identify the effects of different natural products on male infertility extracted from plants.

Methods:

We reviewed the literature and included full-text publications in English provided by international biomedical databases, including Sciences Direct, Google Scholar, OVID, PubMed, and MEDLINE between 2016 and 2023. Search terms, such as fertility preservation, in vitro maturation, cryopreservation, plants for the treatment of male infertility, were taken from Medical Subject Headings (MeSH) and Boolean operators were used to improve sensitivity.

Results:

112 papers were identified in the initial search, of which 18 were excluded due to duplication. After reviewing titles and abstracts, 70 papers were finally included. The main findings of this study are presented under three key themes: gametogenesis, fertility preservation techniques, and plant-based alternatives. Regarding gametogenesis, significant progress has been made in understanding oocyte and sperm maturation, with optimized conditions improving maturation rates and motility. For fertility preservation, techniques such as rescue in vitro maturation and cryopreservation have shown the enhanced outcomes, particularly in maintaining gamete quality. Lastly, plant-based alternatives, including extracts and essential oils, have demonstrated potential in reducing oxidative stress, improving sperm motility, and supporting oocyte development, thus providing a promising complementary approach to conventional methods.

Conclusions:

Fertility preservation is achieved in a variety of ways, including oocyte and embryo vitrification and sperm cryopreservation, and the use of plant-based treatment of male infertility.
Reliability of Measuring Coracohumeral Ligament Stiffness with Different Shoulder Positions of Frozen Shoulders
Authors: Zhang Jingfeng , Wan Yanping , Wang Wenjuan , Meng Jingjing , Yan Yanni , Zhang Lei
Published: December 2024

Background:

Shear wave elastography (SWE) is utilized to detect the stiffness of the coracohumeral ligament (CHL) for the assessment of a frozen shoulder. However, the consistency of shoulder joint posture during the detection process has not been adequately established. This study aims to evaluate the reliability of various commonly employed shoulder postures in measuring CHL stiffness.

Methods:

SWE was used to assess CHL stiffness in 55 patients with phase I frozen shoulder by two independent observers. Two measurements were taken, with a 1-week interval, at three shoulder positions: neutral, 30° external rotation, and 60° external rotation. The intra- and inter-observer reliability of CHL stiffness measurements were analyzed using a two-way randomized model with an intragroup correlation coefficient.

Results:

Significant differences between intra- and inter-observer measurements of CHL stiffness in the neutral position were observed (P < 0.05). However, no significant differences were found at 30° and 60° of external rotation (P > 0.05). Furthermore, poor intra- and inter-observer reliability of CHL stiffness measurements was established in the neutral position intraclass correlation coefficient (ICC < 0.40), moderate reliability at 30° of external rotation (ICC > 0.40, <0.75), and excellent reliability at 60° of external rotation (ICC > 0.75). In addition, the Bland–Altman analyses indicated that the mean differences between intra- and inter-observer measurements of CHL stiffness at 60° of external rotation were closest to the zero scale.

Conclusion:

The reliability of SWE in assessing the stiffness of the CHL in patients with phase I frozen shoulder at 60° external rotation is highly satisfactory.

Universal Health Care for Childhood Cancer in India: Challenges and Solutions for Implementation
Authors: Srivastava Anukriti , Radhakrishnan Nita , Pandharipande Archit , Brar Zeenat , Pandey Amit
Published: December 2024

Introduction:

The World Health Organization has declared a Global Initiative for Childhood Cancer which aims at achieving a cure rate of atleast 60% globally. To achieve this significant planning and policy making would be needed in most LMICs including India. In this setting, having a Universal Healthcare Scheme, that tracks patients from first symptom to diagnosis to treatment and provides free treatment is a laudable effort by the Government of India.

Aims and Objectives:

In this paper, we describe our experience of managing children with cancer on Pradhan Mantri Jan Arogya Yojana (PMJAY) or Ayushman Bharat scheme at our center over a period of 5 years. We also identify and report few suggestions for universal implementation of this scheme in order for better coverage for children with cancers.

Methods:

The data of children aged between 0-18 years who underwent treatment for cancer with financial support from PMJAY scheme between Jan 2018 to December 2022 (5 years) was analyzed from hospital records.

Results:

59 out of 485 children treated for cancer were eligible for PMJAY (Ayushman Bharat Scheme). Only 12% of patients were found to be eligible, even when parent’s card was taken as primary proof. Overall >85% of the families who enrolled in to this scheme were highly satisfied as there were no out of pocket expenses incurred due to early initiation into the program. All patients were enrolled on treatment and 57 children completed treatment successfully. We also identify and report few suggestions for universal implementation of this scheme in order for better coverage for children with cancers.

Conclusions:

PMJAY is a people-centric scheme which provides a complete package from diagnosis to completion of treatment. The program when implemented in its totality would continue to strengthen India’s response towards the Global Initiative for Childhood Cancer.

With the advancement of lightweight magnesium-based hybrid composites, are
potential for weight management applications. The liquid state stir cast process
is the best way to produce complex shapes and most industries are preferred.
However, the melting of magnesium alloy and achieving homogenous particle
distribution are the major challenges for the conventional stir-casting process,
and hot crack formation is spotted due to thermal variations. The main
objectives of the present research are to enhance the microstructural and
mechanical behaviour of magnesium alloy hybrid nanocomposite (AZ91E) adopted
with boron carbide (B4C) and alumina (Al2O3)
nanoparticles through a semisolid stir cast technique associated with inert
atmosphere helps to limits the oxide formation and reduce risk of magnesium
fire. The effect of composite processing and multiple reinforcements on surface
morphology, tensile strength, impact strength, and hardness were thoroughly
evaluated and compared. The results of surface morphology studies demonstrate
homogeneous particle dispersion with reduced casting defects. Furthermore, the
AZ91E alloy hybrid nanocomposite (HNC) exhibits superior tensile strength,
impact strength, and hardness when compared to the monolithic AZ91E alloy,
showcasing improvements of 18%, 23%, and 25%, respectively, which is suggested
for automotive seat frame applications.

Published: December 2024

Nanofluids have emerged as effective alternatives to traditional coolants for
enhancing thermal performance in automotive applications. This study conducts a
comparative analysis of the viscosity and thermal conductivity of ZnO and Cu
hybrid nanofluids. Nanofluids were prepared with ZnO and Cu nanoparticle
concentrations of 0.1%, 0.3%, and 0.5% by volume and were characterized over
temperatures ranging from 25°C to 100°C. The results demonstrate that ZnO and Cu
hybrid nanofluids achieve an increase in thermal conductivity by up to 22% and
28%, respectively, compared to the base fluid. Concurrently, the viscosity of
these nanofluids increases by up to 12% at the highest concentration and
temperature. This study addresses a critical research gap by investigating the
combined effects of ZnO and Cu nanoparticles in hybrid nanofluids, an area that
has been underexplored. By providing new insights into optimizing both thermal
conductivity and viscosity, this research contributes to the development of more
efficient cooling systems for automotive applications.
Study of Effect on Structural Strength of Locally Strengthened Rotor Lamination Stack through Virtual Validation
Authors: Pawde Deepak , Srimathkandala Maithili , Galande Pandurang
Published: December 2024

Rotor and Stator are the key constituents of an electric motor that are made of several laminates punched from a sheet metal and stacked together. The rotor stack is inserted with magnets at the punched-out pockets and is assembled with a shaft via press fitting. Rotor assembly being the rotating part of an E-Motor is subjected to centrifugal loads due to masses of magnets, lamination stack and shaft rotating at high speeds, temperatures and assembling loads because of which rotor laminates experience failures as the high strains develop in the regions on the laminate that support magnets. Typically, these high strain locations are the sections of the magnet pockets one on the outer diameter of the laminate and the other at the sections between the magnet pockets. Traditionally, these high strains are addressed by increasing the area of these sections, but this has a detrimental effect on the electromagnetic performance.

Instead of increasing the area of these sections, the proposed solution of local strengthening of the magnet pockets influences strength of these sections of the lamination stack. Such localized strengthening can be achieved through surface hardening, grain boundary refinement or using high strength magnet inserts. In this paper, an approach for investigating the effect of localized hardening on improvement in strength of rotor laminate is studied using Finite Element Analysis. A comparison is made between the locally strengthened and non-strengthened rotor laminate in terms of deformations and strains.

The article aims to introduce a new voice in the study of the disappearance of the majestic seal in the Polish sphragistic system in the second half of the fifteenth century. In researching this issue, the author places the symbolic meaning of the majestic seal and its use against the background of the political changes in the Poland of the Late Middle Ages and the visual representation of the kings of Poland and the royal rituals at the turn of the Middle Ages and the Early Modern era. According to the author, the disappearance of the Polish majestic seal was the result of the crisis and dispersion of royal majesty as a result of the final extinction of the Piast dynasty at the end of the fourteenth century.
Les avertisseurs communicationnels : formes, fonctionnement et enjeux d’un fait de discours. Présentation
Authors: Djédjé Hilaire BOHUI
Published: December 2024

La constitution d’un espace structuré de théorisation et de problématisation de l’objet « analyse de discours » vue et pratiquée d’Afrique – son histoire, sa vie et sa vitalité – remonte à des décennies en arrière. À son initiative se trouvent des pionniers tels que Vumbi-Yoka Mudimbe de l’Université de Lubumbashi (RDC), sur la période 70-80[1] et Momar Cissé de l’Université Cheikh Anta Diop (Sénégal) durant la décennie 80-90[2]. À cette époque en Afrique subsaharienne en particulier, la mutualisation des savoirs et pratiques n’était au mieux qu’une forte aspiration. En cause, la quasi-inexistence de canaux de diffusion des données disponibles, les communautés universitaires des différents pays étant littéralement cloisonnées, avec le livre physique comme seul moyen de circulation de la pensée et des savoirs. Quand elles étaient disponibles, les informations entre spécialistes d’un même champ disciplinaire circulaient littéralement sous le manteau, leur accessibilité constituant un gros handicap pour la diffusion et le partage des connaissances. C’était alors une communauté universitaire fragmentée de praticien·nes reclus·es au plan national et sans contact véritable soutenu avec leurs pairs de l’extérieur. Au bilan, le résultat des efforts consentis des années durant par ces pionniers sont au mieux mitigés. Mais leur mérite est grand d’avoir porté le statut ingrat d’ouvreur de chemin.
Les avertisseurs communicationnels africains. Contribution à une aventure théorique
Authors: Aimée-Danielle LEZOU KOFFI
Published: December 2024

Le projet d’un dossier thématique sur les avertisseurs communicationnels africains (ACA) vise à élaborer une construction théorique de l’analyse du discours en contexte africain. De nombreux·euses chercheur·euses du Sud global, en particulier en Afrique, soutiennent ce type d’initiative encourageant ainsi la décentration dans la production des savoirs et la valorisation des savoirs endogènes dans les ex-colonies, à travers divers mouvements postcoloniaux et décoloniaux. Cette contribution est inspirée par les travaux de Bohui (2002, 2013) sur les avertisseurs communicationnels, qui mettent en exergue une réalité langagière familière aux locuteur·trices ivoirien·nes et/ou africain·es. En effet, les avertisseurs illustrent une manière anticipative de communiquer, mettant en avant des caractéristiques de la parole africaine au-delà des prouesses rhétoriques de la palabre. Dans une perspective critique, la présente contribution en examine les différents aspects. Elle propose, in fine, que cette initiative inaugure des analyses visant à identifier des traits linguistiques caractéristiques de la parole africaine.

Bien des cas de résolutions de conflits dans les zones rurales rassemblent le conseil de jugement de la chefferie. C’est l’occasion pour les juges traditionnels d’arbitrer les conflits et de permettre à la partie lésée d’obtenir réparation. L’interaction réparatrice induit des rituels de préservation de la face des participant·es sachant que les tensions qu’implique le fait de relater un conflit en vue de le résoudre font planer des menaces potentielles sur les faces. Nous nous proposons de décrire et d’analyser un ensemble de stratégies de politesse investissant l’interaction et dont l’objectif est de préserver les relations interpersonnelles. L’analyse s’appuiera sur la transcription de deux audiences traditionnelles chez les Baoulé en Côte-d’Ivoire. En nous fondant sur l’approche de la politesse linguistique telle que développée par Kerbrat-Orecchioni (2005), plus précisément sur la production des adoucisseurs d’actes menaçants d’une part et d’autre part la production d’actes valorisant la face, nous étudierons la mise en discours du protocole de politesse en contexte africain en nous appuyant sur la théorie des avertisseurs communicationnels africains telle que proposée par Bohui (2002, 2013).

Forecasting electricity production from renewable sources is challenging for producers, distribution and transmission System Operators, electricity traders, and other market participants. To a large extent, to maintain the power system's operational security, System Operators rely on the operational production forecasts of electricity producers. With the greater participation of renewable energy sources in total electricity production, the interest and importance of production forecast from these sources as accurately as possible, and the increasing reliance of the Operator system on the forecasts sent by the producers is growing. A particular challenge in the production forecast from renewable energy sources is the energy obtained from solar, wind, and small run-of-river hydropower plants. Given that with the growing participation of producers in the free market, this topic is becoming more and more relevant, different methods for production forecast and various accompanying software solutions are being reviewed, improved, and developed. Comparative analysis and selection and application of the appropriate method for evaluating forecast accuracy is the topic of this work. After introductory considerations on the importance of the adequate forecast
for renewables production, ways for determining the precision of these solutions and the way to choose the appropriate criterion, i.e., the type of forecast errors for different types of renewable energy sources, is presented. Along with the mathematical formulation, a practical example of calculated different kinds of errors (standard deviation, bias, mean absolute error, mean square error, etc.) is given, together with their normalised percentage values. A description of the samples, flow, and results of calculations for measuring the success of production forecasts for solar, wind, and small hydropower plants is given. At the end of the paper, notes on possible and necessary improvements are briefly given, aimed at better production forecast and more comprehensive analysis of different types of forecast errors.

The paper presents a temporal analysis of the emission of pollutants into the air on the example of the two largest thermal power plants "Nikola Tesla A" and "Nikola Tesla B". The "Thermoelectric Power Plant Nikola Tesla" branch is the largest producer of electricity in Southeast Europe. There are 14 units with a total installed capacity of 3,430 MW. Within the branch of the "Nikola Tesla Thermal Power Plants", there are two constituent entities: the „Nikola Tesla A“ Thermal Power Plant, comprising six blocks with a total projected capacity of 1650 MW, and the „Nikola Tesla B“ Thermal Power Plant, featuring two blocks with a combined electrical capacity of 1,340 MW. Within the "Thermoelectric Power Plant Nikola Tesla A" there are blocks A1 with 660 MW, A2 with 660 MW, A3 with 932 MW, A4 with 943 MW, A5 with 934 MW and block A6 with 934 MW of thermal power, while within the
"Thermoelectric Power Plant Nikola Tesla B" has two blocks B1 and B2 with 1809 MW and 1826 MW of thermal power each. The emission trend is shown for three pollutants, sulphur dioxide, nitrogen oxides and particulate matter for 2022, 2021 and 2020. Flue gases containing pollutants are released into the air through chimneys 150 meters high (blocks A1, A2 and A3) and 220 meters (blocks A4, A5 and A6) at "Thermoelectric Power Plant Nikola Tesla A" and 280 meters high (blocks B1 and B2) at "Nikola Tesla B Thermal Power Plant". In accordance with legal requirements, continuous measurements are performed regularly, while periodic measurements are performed to check the correctness of continuous measurements.

This paper explores the design and implementation of a cart inverted pendulum system, controlled using a model predictive controller. The system has been designed to serve as an educational platform that demonstrates the stabilization of an inherently unstable system. A complete workflow is provided, starting with the computer-aided design, followed by the system modeling and the implementation of a model predictive controller. The controller has been tested through various simulation scenarios, including displacement from stable point and different referent positions, to assess the system’s stability and recovery limits. Simulation results are presented with a brief discussion of the responses. The system has been designed to allow further extensions, making it a versatile tool for control theory education and research.

Bei der Behandlung von Patienten mit einer akuten myeloischen Leukämie (AML), die nicht für eine intensive Therapie ­belastbar sind, kann nach aktuellem Kenntnisstand keine Heilung erzielt werden. Jede antineoplastische Therapie ist jedoch einem rein supportiven Konzept hinsichtlich Lebensqualität und -dauer überlegen. Therapiestandard stellt die Kombination aus Venetoclax mit hypomethylierenden Substanzen dar; beziehungsweise bei Betroffenen mit IDH1-Mutation auch Ivosidenib mit Azacitidin. Eine Behandlung im Rahmen von klinischen Studien sollte immer geprüft werden. Aktuelle Studien könnten mit der Entwicklung neuer zielgerichteter Substanzen, wie zum Beispiel der Gruppe der Menin-Inhibitoren bei Erkrankten mit NPM1-Mutation oder KMT2A-Rearrangement, zur Verbesserung der Langzeitprognose beitragen.
