Authors: Kholimenko I. M. , Seregin S. P. , Rodionova S. N. , Pugzhilis A. V.
Published: April 2024

The purpose of research. Urolithiasis occupies a leading place among all urological diseases after infectious and inflammatory ones. /n addition, it does not lose its relevance due to the fact that the number of patients with this disease is steadily increasing. Тhe aim of the study is to study the peculiarities of changes in renal hemodynamics after minimally invasive methods of treatment of urolithiasis remote shock wave lithotripsy (DLТ) and percutaneous nephrolithotripsy (РNL) to improve the quality of medical care for urological patients.Methods. Numerous studies have shown in detail the effectiveness of using remote shock wave lithotripsy and percutaneous nephrolithotorypsy in the treatment of kidney stones. Тhese methods are minimally invasive, well tolerated by patients, and reduce the risks of complications, but they are accompanied by kidney injury, in particular, microcirculation disorders. Тhe use of the Dopplerographic method of investigation allows for a highly informative assessment of the degree of impaired renal microcirculation for the diagnosis of urolithiasis, including for the assessment of hemodynamics after minimally invasive treatment methods.Results. Тhe work shows that when using dopplerography of renal vessels after remote shock wave lithotripsy and percutaneous nephrolithotorypsy, a violation of hemodynamics after DLТ is noted in dynamics already on the first day. In addition, the terms of normalization of indicators are longer in comparison with hemodynamics after РNL. Аlso, with РNL, there is a gradual increase in blood flow indicators in the dynamics of the postoperative period.Conclusion. Тhe work shows that ultrasound Dopplerography is an effective method of dynamic assessment of renal blood flow, and the indicator of renal damage is the resistance index, mainly in the interlobular arteries.

Published: April 2024

The purpose of the research is investigation of the patterns of crack development in structural elements of aviation equipment from a stress concentrator under the influence of a force stretching along the main axis, symmetrical alternating loads (vibrations) and combined effects in order to determine the criticality of operation of aircraft products with crack-type defects, substantiation or refutation of the need for research and operation of the processes of development of stress-strain states preceding the occurrence of a crack, in systems and complexes of periodic, preflight and operational control of the technical condition of aircraft products.Methods. Еxperimental study of the patterns of crack development from a stress concentrator in structural elements of two form factors: a cylindrical sample (GOSТ 25347-82) simulating a stringer or a load-bearing structural beam, and a plate sample (GOSТ 1497-84), simulating an aircraft skin element. Cylindrical samples were subjected to deformation caused by the kinetics of rotation, plate samples were subjected to uniaxial tensile stress and the effects of alternating loads (vibrations) individually and in combination.Results. Тhe patterns of near-surface and deep crack development, their relationship with the frequency of application of symmetric alternating loads, have been studied. Еxpressions are established for the approximate engineering calculation of the material endurance limit, fracture surface area and constant endurance with an approximation accuracy Proceedings of the Southwest State University. Series: Control, Computer Engineering, of about 0.8. For samples in the form of flat plates, a stress-strain diagram is constructed, clearly illustrating the decrease in the endurance of the material to the effects of combined loads in relation to the effects of static tensile stresses only. Тhe approximate number of residual cycles before the structural element is destroyed is estimated, taking into account the amplitude-frequency parameters of the acting vibration in the presence of a crack in the sample. Тhe estimation method using the load intensity coefficient and mathematical expressions for its calculation is given.Conclusion. /t is concluded that it is necessary to analyze the dynamics of the development of stress-strain states (fatigue) of the material as states preceding the appearance of cracks in order to carry out sufficient control of the technical condition of structural elements of aircraft products.

The purposeof the research is to develop and compare various methods and algorithms for effective particle analysis based on their visual characteristics. Тhe purpose of this article is to develop and compare various methods and algorithms for effective particle analysis based on their visual characteristics. Тhe paper considers two fundamentally different approaches: the analysis of grayscale gradients and the machine learning method.Methods.Тhe research methodology includes the analysis of particle images obtained by precipitation from colloidal solutions after laser ablation and images of powder particles for selective laser melting. Тhe materials were obtained using a Quanta 200 3D electron microscope (FЕ/). For the analysis, threshold brightness binarization, contour recognition methods by the Kenny operator and the Hough algorithm are used to combine boundary points into connected contours. For comparison, the U-Net neural network solution was used, and a dataset generator was created to train the neural network. Hand-cut images of aluminum alloy powder particles and micro and nanoparticles of various metals are used as data for generation.Results.Тhe results of the study show that the Hough method provides recognition of the number of particles at the level of 80%, and the machine learning method achieves 95% accuracy in recognizing the shape of particles. Both methods can be used to analyze microand nanoparticles, including irregularly shaped particles.Conclusion.Тhe findings of the work confirm that neural networks are the optimal solution for automatic particle recognition in digital images. However, in order to create a dataset of sufficient volume, it is necessary to develop a generator of labeled images, which requires a detailed study of the subject area.

Published: April 2024

The purposeof the research is to develop a methodology for classifying complexly structured halftone images based on a multimodal approach using methods of morphological analysis, spectral analysis and neural network modeling.

Methods. А method for classifying the contours of the boundaries of segments of a complexly structured image is described. Тhe method is based on the fact that in chronic diseases of the pancreas, there is a violation of the integrity of the contour of its border and its waviness increases due to retractions and bulges caused by an alterative inflammatory process. Тhe method includes the stages of normalization of ultrasound images and image segmentation with the selection of the contour of the object of interest. Тo classify the contour of a segment boundary, it is proposed to use Fourier analysis and neural network technologies. Тhe method is illustrated using the example of classifying the contour of the border of the pancreas on its transcutaneous acoustic image.Results. Еxperimental studies of the proposed methods and means for classifying medical risk were carried out on diagnostic tasks according to the following classes: "chronic pancreatitis" – "without pathology". For experimental studies, video sequences of ultrasound images of the pancreas provided by an endoscopist were used. Тhe purpose of the experimental studies was to analyze the classification quality indicators of image classifiers with class segments "Chronic pancreatitis" and "Without pathology". Тhe training sample of video images (frames of video sequences) included 200 examples, one hundred from each class. Тhe quality indicator "Sensitivity" of classification for two classes is 85,7%, the indicator "Specificity" is 87,1%.Тhe use of the contour analysis method in classifiers of ultrasound images of the pancreas opens up new opportunities for accessible and objective diagnosis of pancreatic diseases, expanding the capabilities of intelligent clinical decision support systems.

Authors: Usama Usama , Sarwar Muhammad Amad , Awais Muhammad , Khan Muhammad Mukhtar , Sarris Ioannis
Published: April 2024

In this contribution, the numerical analysis of the Casson nanofluid towards a stretching surface is studied. The stagnation flow with thermal radiation effects over an exponentially stretching has been considered. The flow problem governing partial differential equations are converted into the ordinary differential equations along with relevant boundary conditions using appropriate similarities. The resulting ODEs then solved numerically using the Keller box methodology, which is a well-known technique. It can be shown from the comparison that our current results and the earlier ones have a good match. It has been found that the reduced Sherwood number, increases for increasing values of radiation parameter while, Nusselt number and skin friction coefficient decreases. Furthermore, the skin-friction coefficient increases as the inclination factor increases but Nusselt and Sherwood numbers decline. The temperature profile increases with the increasing behavior of radiation factor. Further the magnetic effects reduce the velocity profile.

Authors: Silva Arciniega María Del Rosario
Published: April 2024

En el marco del Programa en Migración y Salud (PIMSA) se realizó el estudio que tuvo por objeto conocer si existe diferencia estadísticamente significativa entre el total de la calificación de la escala de la identidad en una muestra de migrantes y no migrantes de la CDMX, y desde el que se hipotetizó que los migrantes poseen un alto sentido de confianza, autonomía, iniciativa, laboriosidad, identidad e intimidad, y que la vivencia de estas potencialidades les permite tejer el impulso que los lleva a dejar el terruño, la familia, lo propio, para buscar en otro espacio lo que anhelan. Método: se realizó estudio comparativo de campo y transversal. Se administró una escala de medición de Tipo Likert con cinco opciones de respuesta y 77 asertos válida y confiable, construida por la de la voz. La muestra estuvo conformada por 500 personas (250 migrantes y 250 no migrantes) ubicados en la CDMX. Se aplicó análisis factorial de tipo Alfa con rotación varimax, análisis de fiabilidad y comparación entre muestras. Resultados: se obtuvieron nueve factores propios con valor eigen superior a 1.000, varianza acumulada de 45.497 y Alfa de Cronbach de 0.874 para 63 afirmaciones. Los factores obtenidos fueron denominados: 1) Confusión de identidad, 2) Intimidad, 3) Asertividad sexual, 4) Laboriosidad, 5) Afiliación parental, 6) Seguridad básica, 7) Identidad, 8) Confianza y 9) Iniciativa. El primer factor contó con 27 asertos, todos ellos corresponden a elementos ubicados en la desconfianza, vergüenza, duda, culpa, inferioridad, confusión de identidad y aislamiento. El primero de ellos fue Me siento solo, con carga factorial de 0.668, por lo que se observa que la confusión de identidad es el elemento que permea en esta muestra de 500 migrantes y no migrantes ubicados en la CDMX. Se aceptó la hipótesis alternativa que indica la existencia de diferencia estadísticamente significativa entre el total de la calificación de la escala de la identidad entre una muestra de migrantes y no migrantes de la CDMX, favoreciendo a estos últimos con p = 0.051 obtenida por Chi cuadrado. Esto significa que los no migrantes cuentan con una identidad más fortalecida que los migrantes ubicados en esta ciudad.
¿Quiénes son los jóvenes? Una mirada a su religiosidad desde lo social
Authors: Agilar Medina José Iñigo
Published: April 2024

Se analiza el tema de las identidades juveniles en su dimensión religiosa en México. Parte de dos ideas: que su inserción al mundo adulto es problemática y que la institución Iglesia y el ámbito de lo sagrado poco impacto tiene en sus vidas. Explora la relación que mantienen con dicho ámbito, en concreto con los valores que les ofrece la Iglesia, la religión y el lugar que tiene la divinidad en su cotidianidad. Se consultó a 44 universitarios; primero se les requirió ver la película “99 minutos en el cielo” y después que respondieran por escrito un cuestionario que no hace referencia particular a un dios o a un credo. Concluye que los descubre desacralizados y disminuidos en su vida espiritual y critica a la institución Iglesia, en especial a la católica, porque les ha dejado vacíos de la relación comunitaria con el misterio y pregunta: si el numen cristiano ha terminado desacralizado ante el embate de la posmodernidad.

Comparing Traditional and Digital Methods for Detecting Forged Signatures in Forensic Analysis
Authors: Bhadarge Tanuja , Parkhe Devyani
Published: April 2024

Abstract: Signatures are considered proofs for the validation of documents. Forgery of the signature is seen in almost all documents, ranging from bank checks, property papers, legal documents, and so on. The analysis of the signature can be a challenging task for forensic experts as fewer alphabets are used, so finding characteristics is difficult. In this research paper, we have discussed two ways of analyzing forged signatures: traditional and digital methods (Matlab and Python software). Traditional method: manual analysis of forged signatures with the help of a stereomicroscope and magnifying glass; digital method: using Matlab and Python software for analysis. In Matlab software, a curve fitting function is used in which the deviation of the graph is analyzed for both original and forged signatures. In Python software, two samples are added, one of which is the original signature and the other is the questioned sample. For analysis, 400 samples of signatures were used: 200 samples of the original signature and 200 samples of the questioned signature. The main aim of the paper is to find an easy and less time-consuming method for the analysis of the forged signature. The digital method has shown an accuracy of 95%. So it can be said that the digital method requires less time than the traditional method, and the accuracy and efficiency are almost the same.
Holistic Review in Family Medicine Residency Programs: A CERA Study
Authors: Truong Oanh H. , Wang Jenny Y. , Cronholm Peter F.
Published: April 2024

Background and Objectives: Interest in using holistic review for residency recruitment as a strategy to improve the diversity of the physician workforce has increased. However, no data are published on the prevalence of holistic review in the selection process for family medicine residency programs. We designed this study to assess programs’ knowledge, skills, and attitudes; prevalence; barriers to implementation; and program characteristics associated with the use of holistic review.
Methods: Data for this study were elicited as part of a 2023 survey conducted by the Council of Academic Family Medicine Educational Research Alliance. The nationwide, web-based survey was sent to 739 family medicine residency program directors.
Results: A total of 309 program directors completed the holistic review portion of the survey. Programs that understood and agreed with holistic review used it more in their selection process. Holistic review was more common in programs with higher rates of residents, faculty, and patients that are underrepresented in medicine. Barriers to holistic review utilization were increased number of applicants, increased resources associated with holistic review, and lack of consensus on the holistic review approach.
Conclusions: The holistic review process is an area of growing interest to diversify the physician workforce, especially among residencies caring for underresourced communities. Further discussions on the specific scoring rubrics of family medicine residency programs that use holistic review are needed and could help programs that are facing barriers. Widespread use of holistic review to diversify the physician workforce has the potential to improve patient care access and health.
Climate changes have alleviated climatic constraints on forest carbon stocks since 1970 in most areas of the Northern Hemisphere
Authors: wu fang , Jia Junwen , Li Cheng , Cao Yun , Zhao Junfang , Yan Xiaodong , Cui Xuefeng
Published: April 2024

Global climate action is urgent, with forest carbon stock critical for
mitigating climate change, yet vulnerable to its impacts. However, the
long-term dynamics of climate-driven forest carbon stock has not fully
been expressed. Here, we introduce the Forest carbon stock Accumulated
by Single Tree growth (FAST) framework and constructed a counterfactual
scenario to isolate and quantify the impacts of major climatic drivers
on forest carbon stock for 1901-2022. Results show that most breakpoints
in climate-driven forest carbon stock occurred post-1970, with Europe
experiencing the latest, followed by Asia, and North America the
earliest. Furthermore, we observe a prevailing increasing trend in
climate-driven forest carbon stock, especially in post-breakpoints
period (from 53% to 68%), indicating that climate changes have
alleviated climatic constraints on forest carbon stocks in most areas.
FAST can be utilized for historical, current and future forest carbon
stock estimation, providing scientific support for sustainable forest
management decisions.
Geostrophically Constrained Flow of Warm Subsurface Waters Into Geometrically Complex Ice Shelf Cavities
Authors: Finucane Garrett , Stewart Andrew
Published: April 2024

Antarctic ice shelves are losing mass at drastically different rates,
primarily due to differing rates of oceanic heat supply to their
bases. However, a generalized theory for the inflow of relatively warm
water into ice shelf cavities is lacking. This study proposes such a
theory based on a geostrophically constrained inflow, combined with a
threshold bathymetric elevation, the Highest Unconnected isoBath (HUB),
that obstructs warm water access to ice shelf grounding lines. This
theory captures ~90% of the variance in melt rates
across a suite of idealized process-oriented ocean/ice shelf simulations
with quasi-randomized geometries. Applied to observations of ice shelf
geometries and offshore hydrography, the theory captures
~80% of the variance in measured ice shelf melt rates.
These findings provide a generalized theoretical framework for melt
resulting from buoyancy-driven warm water access to geometrically
complex Antarctic ice shelf cavities.
Innovación educativa: Diseño y publicación de aplicaciones en Google Play para adoptar una dieta saludable y sostenible para enfrentar el cambio climático
Authors: Salazar-Ceballos Alexander , Álvarez-Miño Lídice
Published: April 2024

El actual cambio climático es causado por las actividades industriales del hombre y es reconocido como una amenaza de salud pública. Y adoptar una dieta saludable y sostenible porque tiene bajo impacto ambiental y contribuye a reducir las enfermedades como la obesidad, la diabetes mellitus y las enfermedades cardiovasculares. Y la transmisión de esta evidencia es diversa: desde las clásicas conferencias magistrales, bien sea académicas o para todo el público, pasando por el desarrollo de infografías y llegar a adoptar la tecnología digital; y desde esta perspectiva digital, y máxime hoy en día, con la actual pandemia, se hace necesario llegar a los públicos de las regiones más apartadas; de esa manera se han diseñado dos aplicaciones que ya están publicadas en Google Play. Como objetivo se planteó el diseño de aplicaciones, que informaran para todo el público, del impacto del cambio climático sobre la salud pública y que este impacto se puede reducir por la adopción de una dieta saludable y sostenible. Para cumplir con el objetivo, entre enero y septiembre de 2021 se diseñaron dos aplicaciones usando Unity (https://unity.com/es): uno de los motores más avanzados para el desarrollo de videojuegos. Como resultados se obtuvieron las 3 aplicaciones ya se encuentran disponibles en Google Play y se pueden descargar en los siguientes links: 1) Dieta saludable y sostenible (https://play.google.com/store/apps/details?id=com.AlexSalazar.DietaSaludableSostenible); 2) Food Carbon footprint (https://play.google.com/store/apps/details?id=com. AlexanderSalazarCeballos.FoodCarbonFootprint ); 3) Come Sano y Salva El Planeta (https://play.google.com/store/apps/details? id=com.AlexSalazar.ComeSanoSalvaElPlaneta&hl=es_CO&gl=US ). El diseño de aplicaciones para comunicación de la ciencia es más bien reciente. Su difusión es difícil porque Colombia no es un territorio de “ecosistema digital”, si bien se hace uso de las redes sociales digitales, pero no se comparte el conocimiento. En el diseño de las aplicaciones y videojuegos se debe tener en cuenta la interactividad e inmersión. Limitaciones, se hace necesario conocer las habilidades del equipo de diseño para diferenciar entre aplicaciones, las cuales fueron las elaboradas en este trabajo, y que generalmente se basan en dar clicks, o desarrollar vídeojuegos pero estos requieren en un equipo con más habilidades, más tecnología y tiempo, pero los videojuegos pueden llegar a un gran público joven de forma masiva.

Engaging Family Caregivers with Structured Communication for Safe Care Transitions
Authors: Wagner Jesse , Aboumatar Hanan , Treadwell Jonathan R.
Published: April 2024

Objectives. To summarize recent relevant literature on patient safety practices (PSPs) focused on engaging family caregivers with structured communication during care transitions and assess the effectiveness of these PSPs to improve safety during care transitions. This review provides information for clinicians, health system leaders, and policymakers to better inform approaches to engaging family caregivers with structured communication to improve safety during care transitions. Methods. We followed rapid review processes provided by the Agency for Healthcare Research and Quality Evidence-based Practice Center Program. We searched PubMed, Embase, and the Cochrane Library for eligible studies published in 2010 through June 30, 2023, supplemented by targeted gray literature searches and review of reference lists in relevant systematic reviews. We used prespecified inclusion and exclusion criteria to assess relevant studies conducted in the United States that analyzed the effect of structured communication on care transitions with family caregivers. Prespecified clinical and patient-related outcomes included healthcare utilization, symptom exacerbation, quality of life, satisfaction, and unintended harms, among others. Findings. We identified 323 unique citations for possible inclusion; we assessed 86 full-text articles for inclusion. We included nine studies on effectiveness (2 randomized controlled trials, 6 pre-post studies, and 1 single-arm study) which assessed PSPs focused on discharge to home, transfers from intensive care units, and transitions from residential care. In residential treatment facility discharges, we found PSPs improved caregiver satisfaction (low strength of evidence [SOE]). We found insufficient evidence of other PSPs on any other included outcomes. Five studies detailed implementation facilitators, and two studies noted specific barriers to PSP implementation. While no studies specifically reported the resources required to implement PSPs, based on study descriptions, we identified four prominent resource considerations: (1) allocated time for pre-implementation intervention development and staff training; (2) designated time to deliver PSPs to family caregivers; (3) technology-based resources; (4) staff-expertise/addition training for designated roles. None of the studies reported rates of unintended harms. Conclusions. Clear communication with patients and caregivers during care transitions is important, but there is little evidence on the effectiveness of these PSPs. Included studies showed improvement in caregiver satisfaction, but more high-quality research is needed to assess the effectiveness of PSPs and unintended harms.
"Ché Coco, ché Coco": An animal reading of Coco the parrot in Jean Rhys’s Wide Sargasso Sea
Authors: Kangas Reeta
Published: April 2024

The various human characters of Jean Rhys’s novel Wide Sargasso Sea (1966) have attracted the attention of literary scholars from different perspectives. However, the novel’s nonhuman animal characters have previously been studied mainly as symbols for human actions and destinies. In this article, I problematise this type of anthropocentric approach from a Human-Animal Studies and a literary criticism perspective. I analyse Coco as a character of the novel and as a member of his own species. My analysis examines the nature of human-animal relationships, their representations in literature, and the binary oppositions inherent in them. Additionally, I critically evaluate the ways in which nonhuman animals are perceived and depicted in cultural representations. I argue that Rhys shows Coco as a parrot with species-typical behaviour and as a character with his own agency. Nevertheless, one should not disregard his symbolic functions, which draw attention to gendered colonial violence. Furthermore, the symbolic and linguistic violence in the novel forces the nonhuman animal into a position below the human animal and normalises violence towards nonhuman animals. The human-animal relationships in Wide Sargasso Sea vary from something akin to close companionship all the way to subjugation under the will of the more powerful.
Correlations Between Social and National Mobility in Carniola
Authors: PREINFALK Miha
Published: April 2024

The article provides a brief overview of the position of the nobility in Slovenia. First, it focuses on the connection between the nobility and historiography, which from the mid-19th century was increasingly burdened by the national struggles of the past. The findings show that until the mid-19th century the nobility was strongly integrated into Slovenian society, including through the use of the Slovene language, but was then forced into a national definition, and as a rule (with few exceptions) chose to take the German side. More than a change in ethnic identity, a change in social identity was relevant in the early modern period. The new nobility tried as much as possible to adopt and take on a manner of behaviour that suited to their new status. This especially meant the purchase of landed property and forming kinship ties with other noble families. The article concludes with a brief overview of the fate of the nobility in Slovenia after 1918.
Rezumat. Articolul oferă o scurtă prezentare a situaţiei nobilimii în Slovenia. În primul rând, se concentrează asupra legăturii dintre mibilime şi istoriografie, care de la mijlocul secolului al XIX-lea a fost din ce în ce mai mult marcată de luptele naţionale ale trecutului. Concluziile arată că, până la jumătatea secolului al XIX-lea, nobilimea a fost puternic integrată în societatea slovenă, inclusiv prin utilizarea limbii slovene, dar apoi a fost forţată să se definească la nivel naţional şi, de regulă (cu câteva excepţii), a optat pentru o identitate germană. Mai mult decât o schimbare a identităţii etnice, o schimbare a identităţii sociale a fost de asemenea relevantă în perioada modernă timpurie. Noua nobilime a încercat pe cât posibil să adopte şi să preia un mod de comportament adecvat noului lor statut. Acest lucru a însemnat în special achiziţionarea de proprietăţi funciare şi formarea de legături de rudenie cu alte familii nobile. Articolul se încheie cu o scurtă trecere în revistă a sorţii nobilimii din Slovenia după 1918.

The Origins of Avram Iancu’s High Brow “Heroization”: Iosif Vulcan and the Journal “Familia” (1867–1872)
Authors: BOLOVAN Ioan , POP Floarea
Published: April 2024

The present article relies on two papers by the two different authors. The former paper was a talk given in Alba Iulia, at the National Congress of Romanian Historians, in September 2022, by Floarea Pop, the latter was a speech held during the Cluj Academic Days, in October 2022 by Ioan Bolovan. In our opinion, Avram Iancu’s “heroization” was initiated by the Romanian intellectual milieus of the second half of the nineteenth century. Iosif Vulcan and the journal Familia greatly contributed to the creation of the revolutionary leader’s image as a National Hero.
Rezumat: Acest articol se bazează pe două lucrări ale celor doi autori diferiţi.

Odor source location technology has important application value in environmental monitoring, safety emergency and search and rescue operations. For example, it can be used in post-disaster search and rescue, detection of hazardous gas leakage, and fire source detection. Existing odor source location methods have problems such as low search efficiency, inability to adapt to complex environments, and inaccurate odor source location. In this study, based on unmanned aerial vehicle technology and using swarm intelligence optimization algorithm, an improved artificial fish swarm algorithm (IAFSA) is proposed by combining curiosity in psychology on the basis of retaining the good optimization performance of the artificial fish swarm algorithm. The algorithm quantifies the curiosity of artificial fish searching high-concentration areas through a model, dynamically adjusts the artificial fish's field of vision and step length with the calculated curiosity factor, and avoids the oscillation phenomenon in the later stage of the algorithm. Simulation results show that the IAFSA has a higher success rate and smaller location error. Finally, odor source location experiments were carried out in an indoor physical environment, the feasibility of the odor source location method proposed in this study is verified in actual scenarios.

Gear systems in today’s industry are one of the critical pillars providing power transformation and matching speed and torque to application requirements. Reliability, high efficiency, and low operating costs are desirable due to the prevalence of gearboxes. This paper provides a comparative analysis of selected mechanical and magnetic gears, using a specific example to point out the advantages and disadvantages of contactless power conversion. After determining the essence of the operation of the magnetic gear on the base model, two magnetic gear optimization cases are presented, testifying to the application potential. An analysis of the stress distribution in the area of the teeth of the mechanical gearbox and the most stressed element of the magnetic gear - the modulator, was carried out. The effects of temperature and load on losses were measured and simulated, and ultimately, the efficiency characteristics of the two gears were also compared.

The field of ophthalmic surgery demands accurate identification of specialized surgical instruments. Manual recognition can be time-consuming and prone to errors. In recent years neural networks have emerged as promising techniques for automating the classification process. However, the deployment of these advanced algorithms requires the collection of large amounts of data and a painstaking process of tagging selected elements. This paper presents a novel investigation into the application of neural networks for the detection and classification of surgical instruments in ophthalmic surgery. The main focus of the research is the application of active learning techniques, in which the model is trained by selecting the most informative instances to expand the training set. Various active learning methods are compared, with a focus on their effectiveness in reducing the need for significant data annotation - a major concern in the field of surgery. The use of Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs) to achieve high performance in the task of surgical tool detection is outlined. The combination of Artificial Intelligence (AI), Machine Learning, and Active Learning approaches, specifically in the field of ophthalmic surgery, opens new perspectives for improved diagnosis and surgical planning, ultimately leading to an improvement in patient safety and treatment outcomes. The article consists of seven sections. After the introduction, the classic approach to surgical instrument recognition is presented. In sections 3-4 the neural networks and active learning techniques are described. Our algorithm for surgical tool recognition is presented in sec. 5. The article concludes with a discussion.

Objective: the research aims to describe the logistical service system, observing the problematization of agricultural production in the state of Tocantins, considering that this sector is one of the most promising in terms of socioeconomic and regional development in the country.
 
Theoretical benchmark: with the growing advancement of agricultural production and the exploration of new frontiers, Brazil stands out as one of the main exporters of agricultural products today. Given the significant development of agriculture, it is observed that the logistical factor, mainly costs and infrastructure, is among the elements with the greatest impact on the efficiency of the entire agricultural production chain in the state of Tocantins.
 
Method: the methodology adopted will be the deductive method, based on theoretical logistics studies, applicable legislation, and support materials for logistics learning systems, in addition to economic representation in the state of Tocantins. The resources used include bibliographic and documentary material and other instruments or research techniques in accordance with the adopted methodology, aiming to provide support for research on the proposed theme.
 
Results and conclusion: given the content of this study, it is highlighted that the chain of agricultural processes encompasses a complex network of activities in the production chain, and cannot be conceived solely as a relationship between producer and consumer, given its breadth of action. In this context, it should be noted that logistics services end up representing one of the obstacles to the development of agriculture in the State of Tocantins, mainly due to its geographic location.
 
Implications of the research: the approach adopted in this research offers unprecedented scientific contributions to the field of logistics, providing theoretical bases for interventions and public policies that can impact this economic activity in a Brazilian state with strong economic and social growth trends, whose production has repercussions at national and international levels.
 
Originality/value: the social transformations of recent decades, related to the process of globalization of the economy and technology, have directly influenced the social and economic life of countries, affecting production and service chains and interfering in labor relations. Therefore, the increase in regions dedicated to agribusiness activities is a general trend among emerging countries, requiring a deeper understanding of the territorial approach to regional development, especially in economic activities hampered by bottlenecks in the logistics system, both national and international. Thus, new reflections and planning are necessary and imperative elements in Brazilian states like Tocantins.
