Impact of translator mass and buoy choice on a power absorption of point absorbing wave energy converter linear generator with linear generator power take off
Authors: Potapenko Tatiana , Boström Cecilia , Temiz Irina
Published: July 2024

Ocean waves have the potential to contribute to future renewable electricity production. A wave energy converter (WEC) is a technology developed to absorb the energy of the wave and convert it to another form of energy. The Uppsala University WEC (UU WEC) is a point absorber with a direct drive permanent magnet synchronous linear generator power take off. Among other parameters affecting the value of absorbed power for UU WEC are the buoy size, mass of the system consisting of the buoy and translator, and available wave energy at the site of interest. This study reviews the earlier static model that considered only static forces as the buoyancy and gravity forces and neglected all dynamic forces. The static model was proposed to simplify the early‐stage design decision. Although the static model was applied to two UU WECs of different dimensions, the present study shows that the static model is not held for certain buoy and translator dimensions. As an alternative, the dynamic model which accounts for the impact of hydrodynamic forces and various translator masses is proposed. The dynamic model is based on Cummins' equation and the linear potential flow theory, and the damping force is approximated as a viscous damper with the constant damping coefficient optimizing the absorbed mechanical power under a particular sea condition. The dynamic model is applied to four fixed buoy geometries of two shapes (cylinder and cylinder with a moonpool), each of two different dimensions, but the method can be extended to other buoy shapes and dimensions. In addition, the impact of translator mass was assessed for two sites located on the west coast of Sweden and near Gran Canaria, Spain. A translator of 10–11 t promotes 16.8% higher annual average power absorption for a cylindrical buoy compared to a translator of 6 t for the same buoy. However, heavier translators up to 15 t provide only 1.1% increase in average annual absorbed power.

Published: July 2024

The aim of this study was to determine the relationship between the level of psychophysiological compatibility (PPC) and sports qualifications in group rhythmic gymnastics. 20 girls from 4 rhythmic gymnastics sports teams of various sports qualifications participated in this study: one team consisted of athletes of the first adult sports category, two teams – of candidates for master of sports, one – of masters of sports. The level of PPC in the teams was assessed using the hardware and software complex SIGVET-TEAM and the Pearson correlation coefficient (r). The positive relationship between the growth of PPC and sports qualifications was revealed as a result of the study. At the same time, the analysis of the individual result of athletes demonstrates a great variability in the specific contribution within the groups. This fact raises new questions about the importance of PPC at various stages of athletic training in group rhythmic gymnastics.

In the conditions of the information society, the problem of decreased motor activity is aggravating. In the relatively near future, the unresolved nature of this problem will account for people’s impaired health. Therefore, the issues related to the organisation of people’s motor activity and the formation of their need for it become relevant. The purpose of the article is the analysis of the pressing problems of motor activity organisation and formation of the need in it. The reliability of the findings is secured by the integrative approach based on the methods of theoretical analysis of scientific literature and the analysis of the results of fitness testing conducted with the help of fitness trackers. The results of foreign research on the given problem were taken into account. The implemented research leads to the conclusion that the formation of motor activity and the motivation for it is a complex multilevel problem. The analysis of “big data” statistics on the use of personal gadgets has made it possible to systematise the trends and regularities in the formation of motor activity and the need for it.

The effectiveness of the comprehensive health-saving model for university students in uzbekistan in the context of digitalization
Authors: Kodirova Saodat Abdurakhimovna
Published: July 2024

The research is aimed at developing and evaluating a comprehensive health-saving model for university students in Uzbekistan, which includes physical activity, rational nutrition, and psychological support. The study employed mixed methodological approaches, including quantitative and qualitative methods such as surveys, psychological tests, and medical examinations of 300 students divided into three groups: a control group and two experimental groups. The results showed significant improvement in the physical and mental condition of students in experimental group 2, where the level of physical activity increased by 25%, stress levels decreased by 30%, and overall health improved by 18%. Positive changes were also observed in experimental group 1, but they were less significant. The main methodological limitations include the limited observation period and the sample restricted to students from one region. The study’s results confirm the high effectiveness of the comprehensive approach to health-saving, highlighting the necessity of integrating physical exercises, dietary recommendations, and psychological support into educational programs to improve students’ health.

The paper defines the importance of resort treatment in Russia. It is established that the system is being reformed in terms of creating new recreational clusters and consolidating existing organizations by merging and modernizing them. All this complicates the structure of new organizations and increases the number of business processes. Effective management requires specialized software products that direct and monitor processes and resources of medical organizations; this substantiates the relevance of the work carried out. Using structural and mathematical analysis, quantitative and qualitative characteristics of key processes are established. Based on the results obtained, their formal model is developed and the concept of an information system is created. A description of the functional capabilities of the system and the categories of users to whom they are available is presented.

Published: July 2024

The current state of the problem shows that climate change is accompanied by a certain impact on the basic parameters of human life, among which a special place is occupied by the problem of water resources, their quality, quantity, possibilities of consumption, purification and others. In this regard, much attention is paid to assessing the quality of consumed water, since its use is determined by a number of factors, including: irrational use, pollution (chemical/biological), uneven distribution. A rather complex environmental situation has formed in the Kyrgyz Republic, associated with an increase in the level of man-made pressure on the environment. This influence, in turn, is accompanied by the emergence of new problems of protection and reproduction of geo- and biological resources. To analyze the quality of river water samples of the Alamedin River (spring and autumn samples) were selected, followed by purification with modified humic materials in the form of humic composites containing hybrid nanoparticles of iron oxide and rare earth metals. The purpose of the work is to study the influence of sorption modes on modified humic composites when analyzing water samples from the Alamedin River.

Maladie de Sjögren : de la physiopathologie aux avancées thérapeutiques
Authors: Mariette Xavier
Published: July 2024

La maladie de Sjögren (SjD) est une maladie auto-immune systémique caractérisée par une triade de symptômes clés affectant presque tous les patients (sécheresse salivaire et lacrymale, douleur et fatigue) et une atteinte systémique extra-glandulaire pouvant toucher un à deux tiers des patients. Au cours de la dernière décennie, les connaissances sur l’épidémiologie, les critères de classification, l’évaluation de l’activité systémique et des symptômes présentés par les patients se sont développés. En outre, les progrès réalisés dans la compréhension de la physiopathologie du SjD ont permis d’adopter une approche thérapeutique plus ciblée. La prise en charge actuelle du SjD s’appuie sur les recommandations thérapeutiques de l’EULAR. Mais depuis ces recommandations, de nouveaux médicaments ciblant des voies physiopathologiques spécifiques de la maladie, et essentiellement l’activation du lymphocyte B, ont montré une efficacité dans des essais de phase 2. Dans cette revue, nous résumerons les données factuelles disponibles sur les traitements systémiques, y compris : 1. les progrès dans l’évaluation des résultats, 2. les preuves actuelles concernant les traitements de fond ciblés et les biomédicaments ciblant essentiellement les lymphocytes B, 3. une vue d’ensemble des médicaments prometteurs testés dans les études en cours.
The modelling error in multi-dimensional time-dependent solute transport models
Authors: Masri Rami , Zeinhofer Marius , Kuchta Miroslav , Rognes Marie E.
Published: July 2024

Starting from full-dimensional models of solute transport, we derive and analyze multi-dimensional models of time-dependent convection, diffusion, and exchange in and around pulsating vascular and perivascular networks. These models are widely applicable for modelling transport in vascularized tissue, brain perivascular spaces, vascular plants and similar environments. We show the existence and uniqueness of solutions to both the full- and the multi-dimensional equations under suitable assumptions on the domain velocity. Moreover, we quantify the associated modelling errors by establishing a-priori estimates in evolving Bochner spaces. In particular, we show that the modelling error decreases with the characteristic vessel diameter and thus vanishes for infinitely slender vessels. Numerical tests in idealized geometries corroborate and extend upon our theoretical findings.
Approche diagnostique des épanchements pleuraux
Authors: Cannone-Guibert Morgane
Published: July 2024

L’espace pleural est délimité par les plèvres viscérale et pariétale. A l’état physiologique, une très faible quantité de liquide pleural est présente pour favoriser le glissement des lobes pulmonaires lors des mouvements respiratoires. La production et la résorption de liquide pleural sont soumises aux forces de Starling, et une partie du drainage est assurée par le système lymphatique.

Les cinq mécanismes responsables d’un épanchement pleural incluent une augmentation de pression hydrostatique, une baisse de pression oncotique, une réduction des capacités de drainage lymphatique, une augmentation de la perméabilité endothéliale ou mésothéliale, ou encore une rupture vasculaire ou viscérale. Ainsi, de très nombreuses affections peuvent être responsables d’un épanchement pleural. On distingue les transsudats purs, les transsudats modifiés et les exsudats en considérant la concentration en protéines, la cellularité totale et l’examen cytologique de l’épanchement. Cette classification comporte néanmoins des limites.

Il peut s’avérer pertinent, comme en médecine humaine, de s’aider d’autres paramètres pour ne finalement distinguer que deux catégories, transsudats et exsudats (critères de Light) en comparant notamment la concentration en protéines totales entre l’épanchement et le sérum ou en dosant l’activité de la lactate deshydrogénase (LDH) dans l’épanchement.

Lors d’hémothorax, une mesure du microhématocrite dans l’épanchement est nécessaire. Une décompensation cardiaque chez le chat peut être identifiée en dosant le NT-proNBP dans le sang et l’épanchement.

Lors de pyothorax, de chylothorax, de bilothorax ou d’urothorax, il convient de comparer les concentrations dans l’épanchement et dans le sérum du glucose et lactates, des triglycérides, de la bilirubine et de la créatinine, respectivement. Selon les premières analyses et la nature identifiée de l’épanchement, d’autres examens complémentaires peuvent ensuite s’avérer indispensables : imagerie médicale (scanner thoracique, échocardiographie, échographie abdominale), culture bactériologique, recherche PCR, bilan d’hémostase, ...
Le pyothorax chez le chien et le chat :
démarche diagnostique
et prise en charge thérapeutique
Authors: Ragetly Chantal
Published: July 2024

Un pyothorax est l’accumulation d’exsudat dans la cavité pleurale. Le facteur déclenchant est la présence d’un agent infectieux dans la cavité thoracique qui entraîne une réponse inflammatoire et l’accumulation de liquide dans l’espace pleural.

Le mécanisme exact par lequel la cavité pleurale s’infecte n’est souvent pas clairement déterminé ; de nombreuses voies d’infection sont cependant citées chez les chiens et les chats : migration d’un corps étranger, plaie thoracique pénétrante, extension d’une infection pulmonaire, voie hématogène et causes iatrogènes.

Le diagnostic est souvent aisé et basé sur les signes cliniques, l’examen radiographique, la thoracocentèse, la cytologie et la mise en culture de l’exsudat.

L'affection peut être traitée par des moyens médicaux et / ou une intervention chirurgicale. La prise en charge médicale qui comprend l'utilisation de drains thoraciques, l’aspiration de l'exsudat, des éventuels lavages thoraciques en association avec un traitement antimicrobien parentéral est le traitement initial de choix.

Authors: Dekerle Bastien , Manassero Mathieu
Published: July 2024

Le chylothorax correspond à l’accumulation de chyle, liquide lymphatique riche en triglycérides transporté depuis les vaisseaux lymphatiques mésentériques, au sein de la cavité pleurale. Il s’agit en général d’une affection chronique, d’évolution insidieuse, qui peut être à l’origine d’une détresse respiratoire aiguë.

Lorsqu’aucune cause de chylothorax n’est identifiée au cours des examens complémentaires réalisés, le chylothorax est qualifié d’idiopathique et son traitement est volontiers chirurgical car les carnivores domestiques, en particulier le chien, répondent peu au traitement médical. Pour autant, aucun consensus de traitement n’est établi.

Si la pierre angulaire du traitement chirurgical d’un chylothorax idiopathique est la ligature du canal thoracique, sa combinaison avec d’autres techniques comme l’ablation de la citerne du chyle ou la péricardectomie subtotale permettent d’augmenter le taux de réussite de l’intervention (60-100 p. cent vs 50-60 p.cent chez le chien).

Il semble que le marquage des voies lymphatiques, pré, per et post-opératoire, permette d’améliorer le pronostic grâce à l’identification précise des voies lymphatiques.

L’intervention chirurgicale est complexe et associée à une importante morbi-mortalité liée, en particulier, à l’abord chirurgical invasif.

Récemment, les techniques vidéo-assistées se sont imposées comme l’alternative à privilégier, assurant à la fois une faible morbi-mortalité et un haut taux de guérison (jusque 95 p.cent ).
Les tumeurs de l’espace pleural
Authors: Floch Franck
Published: July 2024

Les tumeurs de l’espace pleural sont rares chez le chien et le chat, et sont principalement représentées par des tumeurs primitives, les mésothéliomes, et des tumeurs métastatiques, les carcinomatoses et sarcomatoses. Elles se rencontrent préférentiellement chez des animaux âgés, avec présence d’un épanchement pleural, donc de signes cliniques respiratoires ou généraux.

La démarche diagnostique doit donc être raisonnée, et repose en première intention sur l’analyse complète et l’examen cytologique du liquide pleural après thoracocentèse.

L’imagerie médicale est fréquemment nécessaire, dans le cadre d’une démarche d’exclusion ou du bilan d’extension, avec une place de choix des radiographies thoraciques, de l’échographie, et de l’examen tomodensitométrique. Lors de mésothéliome pleural, les examens précédemment cités présentent de nombreuses limites, et la réalisation de biopsies pleurales par thoracotomie ou thoracoscopie est donc indispensable afin d’établir un diagnostic de certitude, en vue d’un examen histologique et immunohistochimique.

Le traitement des tumeurs pleurales reste, à ce jour, non consensuel en médecine vétérinaire, et vise principalement à assécher l’épanchement pleural, soit par chimiothérapie intracavitaire, soit par pleurodèse, soit par des techniques de drainage de l’épanchement. Ces traitements n'étant que palliatifs, le pronostic reste toujours réservé sur le long terme, et des suivis réguliers sont nécessaires.

Moustiques, dirofilarioses canines
et changements globaux en France
Authors: Liénard Emmanuel
Published: July 2024

Deux espèces de filaires sont enzootiques en Europe et en France. Il s’agit de Dirofilaria immitis responsable de la dirofilariose cardio-pulmonaire et de Dirofilaria repens, agent de la dirofilariose sous-cutanée.

Le réservoir principal est le Chien mais ces filaires peuvent infester également l’Homme et le Chat. Elles sont vectorisées par des moustiques de la famille des Culicidés. Culex pipiens demeure le vecteur principal en Europe occidentale. Toutefois en lien avec les changements globaux, Aedes albopictus, invasif en Europe et vecteur compétent pour ces deux filaires, participerait aux modifications épidémiologiques de ces deux filarioses désormais considérées émergentes en dehors des pays du pourtour méditerranéen où elles sévissent de façon enzootique.

En France, les aires de distribution de D. immitis (région méditerranéenne principalement) et de D. repens ne se superposent pas totalement, D. repens ayant une répartition plus vaste.

Afin de déterminer avec précision l’impact des changements globaux et de l’introduction de moustiques invasifs sur la dispersion et la prévalence de ces filaires en France, il est urgent de réaliser de nouvelles enquêtes épidémiologiques dans les populations canines et félines.

Monitoring the Breath-Hold Training Load during an Ecological
Session: A Pilot Study
Authors: Allinger Jérémie , Bouyeure Antoine , Noulhiane Marion , Lemaitre Frederic
Published: July 2024

This study aimed to create a training load index to measure physiological stress
during breath-hold (BH) training and examine its relationship with memory
performance. Eighteen well-trained BH divers (Age: 35.8±6.6 years, BH training
practice: 5.3±4.5 years) participated in this study. During a standard 1.5-hour
BH training in the pool, perceived exertion, heart rate, distance, and duration
were measured. The training load index was modelled on the basis of a TRIMP
(TRaining IMPulse) with four different equations and was used to measure the
stress induced by this BH training. A reference value, based on the ratio
between the average heart rate during all BHs and the lowest heart rate during
BH training, was used for comparing training load index. Memory assessment was
conducted both before and after this training. Of the four equations proposed,
equation no. 4, named aTRIMP for “apnoea,” showed the strongest correlation with
our reference value (r=0.652, p<0.01). No difference was found between any of
the memory tests before and after the BH training. The aTRIMP was a new
representative index for monitoring habitual training of well-trained BH divers.
Furthermore, this training had no negative impact on memory performance.

Background While direct oral anticoagulants (DOACs) may be viewed as simpler to manage then warfarin, they present their own unique management challenges resulting in frequent off-label dosing. It is unknown to what extent off-label dosing occurs when a patient is started on a DOAC versus later in their treatment.

Objectives We aimed to better characterize when off-label DOAC dosing is occurring and to evaluate the effectiveness of prescribing oversight using a registry-based intervention.

Methods We evaluated data from the Michigan Anticoagulation Quality Improvement Initiative (MAQI2) registry, a retrospective quality-improvement process using data abstractors, from 2018 to 2022 on the number of “alerts” that are generated in response to dosing deviating from the U.S. Food and Drug Administration instructions for atrial fibrillation (AF) and venous thromboembolism (VTE).

Results Among a sample of 789 to 1,022 annual AF patients and 381 to 484 annual VTE patients prescribed a DOAC in the MAQI2 registry, off-label dosing was relatively common. Over the 5-year period (2018–2022), there were 569 alerts for AF patients and 162 alerts for VTE patients. Alerts occurred more frequently during follow-up than at the time of initial prescribing in AF patients (78.2 vs. 21.8%), but more commonly at initial prescribing in VTE patients (59.9 vs. 40.1%). After initial review by quality-improvement abstractors, 19.3% of AF alerts and 14.8% of VTE alerts resulted in contact to the prescriber. When the prescriber was contacted, it led to an intervention about 75% of the time for both populations. The most common intervention was a change in DOAC dosing.

Conclusion This study demonstrates the benefit of DOAC prescribing oversight using a registry-based intervention to monitor for off-label dosing for the entirety of the time period a patient is prescribed DOAC, particularly for patients with AF, as off-label prescribing occurs frequently during the follow-up period.

Noise suppression for an aeromagnetic measurement system on an unmanned helicopter
Authors: Li J. , Ge J. , Zhang G. , Li Y. , Wu L. , Wu X. , Fan S.
Published: July 2024

An unmanned helicopter is one of the main platforms for conducting unmanned aerial vehicle aeromagnetic measurements and combines the advantages of rotary-wing and fixed-wing unmanned aerial vehicles. However, unmanned helicopter-based aeromagnetic measurement systems face complex static magnetic noise and maneuvering magnetic interference, which limit their practical performance. To address this issue, an improved multi-channel frequency measurement algorithm for the optically pumped magnetic sensor is proposed to suppress the static magnetic noise proportional to the frequency noise generated by the random quantization error and the airborne electromagnetic interference. A novel aeromagnetic compensation method for the maneuvering magnetic interference is then proposed to weaken the negative effects of the strong multicollinearity of the attitude parameters of the unmanned helicopter on the compensation accuracy and stability by introducing a regularization term and weight matrix. In addition, dedicated software is developed for the real-time calculation and compensation of magnetic interference fields. A dedicated unmanned-helicopter-based aeromagnetic measurement system is developed, and ground and flight experiments are carried out. The ground test results indicate that the static noise of the proposed system is only 0.000 82 nT. In the flight experiments, the system achieves an improvement ratio of 8.33, which is higher than the improvement ratio of 4.37 for a state-of-the-art commercial compensator. Furthermore, the dynamic noise after compensation decreases by 37.6% from 0.0157 to 0.0098 nT.

We present progress in utilizing a machine learning (ML) assisted optimization framework to study the trends in a parameter space defined by spectrally shaped, high-intensity, petawatt-class (8 J, 45 fs) laser pulses interacting with solid targets and give the first simulation-based overview of predicted trends. A neural network (NN) incorporating uncertainty quantification is trained to predict the number of hot electrons generated by the laser–target interaction as a function of pulse shaping parameters. The predictions of this NN serve as the basis function for a Bayesian optimization framework to navigate this space. For post-experimental evaluation, we compare two separate neural network (NN) models. One is based solely on data from experiments, and the other is trained only on ensemble particle-in-cell simulations. Reviewing the predicted and observed trends across the experiment-capable laser parameter search space, we find that both ML models predict a maximal increase in hot electron generation at a level of approximately 12%–18%; however, no statistically significant enhancement was observed in experiments. On direct comparison of the NN models, the average discrepancy is 8.5%, with a maximum of 30%. Since shot-to-shot fluctuations in experiments affect the observations, we evaluate the behavior of our optimization framework by performing virtual experiments that vary the number of repeated observations and the noise levels. Here, we discuss the implications of such a framework for future autonomous exploration platforms in high-repetition-rate experiments.
Analytical derivation and numerical simulation of the ablation rate of a spherical target
Authors: Han Yan-Zhao , Liu Yun-Xing , Li Ying-Jun
Published: July 2024

This paper presents a quasi-steady-state analytical model of the plasma conduction region of a spherical target, and the model is used to analyze the factors that influence the mass ablation rate during laser ablation. Unlike in the case of planar geometry, the mass ablation rate changes as the distance to the ablation front increases. For the plasma in the heat-conduction region of the spherical target under certain conditions, the new analytical model provides relevant parameters such as the density, pressure, and sound velocity, and its results align with those from one-dimensional hydrodynamic simulations. The model and results presented here are valuable resources for investigating mass ablation rates in laser fusion processes.
Preparation and mechanical performance analysis of porous Ti6Al4V scaffold fabricated by direct ink writing

Published: July 2024

In order to mitigate the stress-shielding effect resulting from the stiffness disparity between titanium alloy and bone, the use of additive manufacturing to create porous Ti6Al4V components shows promise for orthopedic implant applications. In this study, a novel hot-melt–quick-frozen polyvinyl alcohol hydrogel was developed for direct ink writing to create porous titanium structures using Ti6Al4V powders with an irregular morphology. The rheological and sintering properties of inks with varying solid phase contents were examined to assess their molding quality. Furthermore, the effect of porosity on the morphology, shrinkage, and mechanical properties of the scaffolds was thoroughly investigated. The results of the experiments show that inks loaded with 65 vol. % Ti6Al4V particles exhibit the highest printing performance. Furthermore, the analysis revealed a positive correlation between the total porosity of the scaffold and its mechanical performance. In particular, the strength of the scaffold with a porosity of 54.8% exceeded that of human bone, and it also exhibited matched stiffness. Upon analyzing the final microstructure and mechanical properties, it is evident that these scaffolds meet the necessary criteria for use as orthopedic implants.

The changes in the crystal structure and ferroelectric properties of (Al0.8Sc0.2)N films sandwiched between Pt and TiN electrodes were investigated by subjecting the films to post-heat-treatment at various temperatures up to 600 °C in both H2 and Ar gases. The remanent polarization underwent slight change, whereas the coercive field strengthened by approximately 9% as a result of the post-heat-treatment up to 600 °C irrespective of the atmosphere and electrode material. This change is much smaller than that reported for ferroelectric (Hf,Zr)O2 films as well as for Pb(Zr,Ti)O3 and SrBi2Ta2O9 films for a wide temperature range from 400 to 600 °C and is almost independent of the Pt and TiN electrodes. The high stability of (Al,Sc)N films with both Pt and TiN electrodes under H2 atmosphere is highly promising to stabilize the properties through the device fabrication process.
