Authors: Auer Alejandra , Mikkelsen Claudia Andrea , Laterra Pedro
Published: November 2024

El modo de producción agrícola industrial actual pone en riesgo la viabilidad e integridad de los socioecosistemas en general y de la provincia de Buenos Aires, Argentina, en particular. Uno de los factores que puede incidir en el nivel de adopción de innovaciones tecnológicas orientadas a reducir los impactos ambientales es la vinculación lograda entre los diferentes actores que intervienen en el territorio y de su compromiso ambiental, cultural, social y político. El objetivo del trabajo es analizar el grado de vinculación existente entre el nivel de adopción de las innovaciones tecnológicas sustentables por parte de los/las productores/as agropecuarios y el nivel de congruencia o acople entre las narrativas de representantes de la academia, la extensión y el ámbito productivo. Para avanzar en la caracterización de este vínculo se aplicó una metodología cuantitativa empleando técnicas que permitieron obtener y sistematizar información primaria y secundaria. Los resultados muestran una relación negativa entre la adopción de ciertas innovaciones tecnológicas sustentables y el nivel de desacople de las narrativas entre los actores estudiados, particularmente en referencia al aporte de las prácticas a la sustentabilidad del agroecosistema. El desacople es mayor entre productores y la academia, siendo necesario fomentar el trabajo transdisciplinario.

Authors: Birche Mariana , Varela Leandro
Published: November 2024

El objetivo del trabajo es desarrollar un diagnóstico urbano del espacio público en dos corredores principales de La Plata: Camino General Belgrano y Camino Parque Centenario. El concepto de corredor es abordado de manera holística, entendiéndolo como algo más que el soporte pasivo de la movilidad. Así, se los comprende como espacios estratégicos para el uso público y para la conformación del paisaje urbano. Es por esto que se analizan las dimensiones de morfología y paisaje urbano, usos del suelo, equipamiento y percepción social. Se identifican problemáticas y también lineamientos de acción enriquecidos por la activa participación vecinal en los talleres de diagnóstico.

Introduction. The issue of choosing the optimal anesthesia that is least dangerous to the patient’s life is still the main concern of the workers in the anesthesia and intensive care department. This includes techniques, medications, plans, and instructions followed in order to choose the best anesthesia. It can also be said that spinal anesthesia is the best and most standard anesthesia for those who repair hernia. Aim of the study. Learning about obtaining and verifying hemodynamic stability in patients undergoing hernia repair under anesthesia. Subjects and methods. An accurate and recent study was performed on patients attending Al-Hussein Medical City and Al-Hassan Hospital in the city of Karbala. We included 100 patients aged 20-90 who underwent a herniotomy by dividing them into two groups according to the type of anesthesia - general (GA) and spinal (SA). Fifty patients received general anesthesia and other 50 received spinal anesthesia. Data related to the patients' age, weight, change in blood pressure and pulse rate were analyzed. A careful follow-up was performed before, during, and after operations. Results. We revealed that the blood pressure is more stable in SA (56%) in comparison to GA (40%), but the increased blood pressure rate is higher in GA (32%) than in SA (24%). However, we have noticed that also the decreased blood pressure is more prevalent in GA (28%) than in SA (20%). Regarding the heart rate, there is more stability in heart rate of SA (56%) than of GA (32%) and the increase in heart rate was 34% in SA while it was 60% in GA. The decreased heart rate was 10% in SA and about 8% in GA, and the effect of SA is more stable. Conclusions. We found out that the spinal anesthesia was better than general anesthesia in stability of blood pressure and normal heart rate.

Authors: Husin Hafiz , Mat Nawi Mohd Nazir , Gebremariam M.A. , Saptaji Kushendarsyah , Azhari Azmir
Published: November 2024

The surface texturing method is popular because of its ability to improve surface properties, specifically surface functioning, and friction control. It is a common technique used on material surfaces to improve friction performance. Laser surface texturing is the popular choice; however, this method suffers drawbacks such as cracking, heat-affected zone, and generation of hazardous fumes. The Abrasive Water Jet Machining (AWJM) was chosen is that, because the eroded material is carried by the waterjet, the process is clean and does not produce dust, chips, or chemical contaminants. This experiment examines the influence of AWJM and investigates how crater density and a multiple-pass machining path affect the stainless-steel friction characteristics when sliding in dry conditions. The texture was applied on the surface of stainless steel by masked multi-passes AWJM technique. According to the findings, there is less friction in craters with greater densities because there are more craters in the contact zone, which improves the trapping of debris particles and reduces friction, when the crater density rises from 4% to 18%, there is a greater chance of worn debris becoming trapped, which reduces friction. The coefficient of friction and crater roughness of the stainless-steel surface are all proportionally affected by the multiple-passes approach. The coefficient of friction increases with higher machining passes. There is more erosion and greater roughness when there are more jet passes. It is concluded that the masked multiple passes AWJM Surface Texturing technique has a significant impact on the Coefficient of Friction (COF).
Numerical Solution of Burgers Equation Using Finite Difference Methods: Analysis of Shock Waves in Aircraft Dynamics
Authors: Abada Hashim , Nemah Mohammed Najeh
Published: November 2024

In this research, the Lax, the Upwind, and the MacCormack finite difference methods are applied to the experimental solving of the one-dimensional (1D) unsteady Burger's Equation, a Hyperbolic Partial Differential Equation. These three numerical analysis-solving methods are implemented for accurate modeling of shock wave behavior high-speed flows that are necessary for aerospace engineering design. This research analysis proves that the MacCormack technique is the one that treats the differential equations with second-order accuracy. This method is quite preferred when it comes to numerical simulations because of its advanced level of accuracy. Although the Upwind and Lax methods are slightly less accurate, they show the development of shock waves that give visualizations to better understand the flow dynamics. Also, in this study, the impact of varying viscosity coefficients on fluid flow characteristics by using the lax (a numerical method for solving the viscous Burgers equation) is investigated. This identification of the phenomenon sheds light on the behavior of boundary layers, which, in turn, can be used to improve the design of high-speed vehicles and lead to a greater understanding of the area of ​​fluid dynamics.
Numerical Study on the Effect of Installing Circular Cylinders in Front of the Returning Blade and Beside the Advancing Blade of the Savonius Wind Turbine

Published: November 2024

Previous research has proven that placing a disruptive cylinder in front of the Savonius wind turbine’s returning blade can significantly increase the performance of the Savonius turbine. In this study, two-dimensional unsteady simulations with a quadratic pave-type structured mesh showed that the circular cylinder placed in front of the returning blade and next to the advancing blade provides the best performance results at a free flow speed of 5 m/s and a Reynolds number of 100,000. In this study, the comparison with experimental data from another study is utilized. The Savonius turbine is installed with an interfering cylinder in front of the returning blade and next to the advancing blade; the air is tighter on the concave side of the advancing blade. The coefficient pressure difference between the convex and concave sides of the blade increases. The maximum moment is achieved in the turbine with a disturbance cylinder at a configuration distance of S/D 1.4 – Y/D 1.61. The maximum moment coefficient is obtained at the position θ = 15°. The placement of two cylinders with a ratio variation of 0.5 D can significantly influence turbine performance. Results show the turbine provides the highest Power Coefficient when TSR = 0.6. The power coefficient increased by 25.11% compared with that of conventional Savonius turbines. Therefore, it can be concluded that the turbine is the optimal configuration for generating the highest power.

Published: November 2024

The analysis of the rotation outcomes for the viscous, incompressible, electrically conducting Jeffreys fluid in an infinite vertical plate through the revolution impacts has been explored. This is owing to the exponential exciting perpendicular absorbent plate embedded in the permeable medium by allowing for ramped surface temperature into the endurances of thermal radiation. The essential governing sets of equations for the flow are translated into non-dimensional form with insert appropriate parameters as well as variables; therefore the resultant equations are computationally resolved by the well-organizing Laplace transform methodology. The influences of numerous significant considerable parameters for the modelling on the velocity, temperature and concentration of the liquid, and the skin friction coefficient, Nusselt number and Sherwood number for together thermal conditions have been deliberated and exploring strongly by producing of graphical profiles and tabular format. This is determined that, with increasing quantities of the rotation, thermal radiation parameters, the fluid temperature as well as velocity enhances. Similarly, this is notified that, a mounting in porous parameter reasons to escalate fluid velocity in addition to concentration reversal results are noticed by the chemical reaction parameter.
Phytosomes as Novel Drug Delivery Methods
Authors: Pathak Anurag , Faijan Moh , Adil Tahseen Mohd
Published: November 2024

As newly identified phytochemicals increase, studies on their potential medicinal applications in biological contexts will be updated. Nevertheless, these chemicals' limited solubility and susceptibility to degradation limit their use in medicinal and food applications. Currently, learning more about vesicular drug delivery methods may aid in enhancing these features. Because of their exceptional trapping capability, safety, and biocompatibility, vesicles have been demonstrated to be extremely promising delivery methods for a variety of beneficial phytochemicals at a cellular level. Phytosomes, a kind of vesicular drug carrier, combine phytochemicals with phospholipids to produce a complex that enhances compound stability overall and improves the absorption and bioavailability of bioactive compounds. One of the newest, smaller-sized lipid-based vesicles to increase the transport of plant- based nutraceuticals is the nano-phytosome. To guarantee a good safety profile and fulfill repeatability requirements, physical measurements that provide details on the dynamics of release and formulation stability must be thoroughly analyzed. Although there is presently not enough data from clinical trials to make judgments about the biological activities of specific preparations, the overall strength of the evidence supporting these formulations is positive and encourages more study in this area. Clinical trials on standardized products that demonstrate greater effectiveness than unformulated components or extracts will be essential in the future to raise awareness of these technologies.

Published: November 2024

Cities, which are a product of human societies and the construction of civilization, are places where individuals spend a significant part of their daily lives. In this respect, the way urban space is organized and the qualities it possesses deeply affect urban life and usage practices. In this context, the research aims to reveal the relationship between spatial configuration and land uses in the region defined as the core of Ordu city centre with analytical methods. The main method followed in the study is based on the space syntax approach, which quantitatively reveals the spatial structure that constitutes the city. As a result of the study, a consistent relationship was found between the findings obtained from axial analysis and the uses in the space. The zone with the highest intelligibility is Zone 6, which is characterized by low-density commercial areas. The zone with the highest synergy value is Zone 7, which includes urban residential areas and low-density commercial areas.

The redshift-dependent relation between galaxy stellar mass and star formation rate (SFR), known as the star-forming sequence (SFS), is a key observational yardstick for galaxy assembly. We use the SAGAbg-A sample of background galaxies from the Satellites Around Galactic Analogs (SAGA) Survey to model the low-redshift evolution of the low-mass SFS. The sample is comprised of 23,258 galaxies with Hα-based SFRs spanning

and z < 0.21 (t < 2.5 Gyr). Although it is common to bin or stack galaxies at z ≲ 0.2 for galaxy population studies, the difference in lookback time between z = 0 and z = 0.21 is comparable to the time between z = 1 and z = 2. We develop a model to account for both the physical evolution of low-mass SFS and the selection function of the SAGA Survey, allowing us to disentangle redshift evolution from redshift-dependent selection effects across the SAGAbg-A redshift range. Our findings indicate significant evolution in the SFS over the last ∼2.5 Gyr, with a rising normalization:

. We also identify the redshift limit at which a static SFS is ruled out at the 95% confidence level, which is z = 0.05 based on the precision of the SAGAbg-A sample. Comparison with cosmological hydrodynamic simulations reveals that some contemporary simulations underpredict the recent evolution of the low-mass SFS. This demonstrates that the recent evolution of the low-mass SFS can provide new constraints on the assembly of the low-mass Universe and highlights the need for improved models in this regime.
Rates and Beaming Angles of Gamma-Ray Bursts Associated with Compact Binary Coalescences

Published: November 2024

Some, if not all, binary neutron star (BNS) coalescences, and a fraction of neutron star–black hole (NSBH) mergers, are thought to produce sufficient mass ejection to power gamma-ray bursts (GRBs). However, this fraction, as well as the distribution of beaming angles of BNS-associated GRBs, is poorly constrained from observation. Recent work applied machine learning tools to analyze GRB light curves observed by Fermi/Gamma-Ray Burst Monitor (GBM) and Swift/Burst Alert Telescope (BAT). GRBs were segregated into multiple distinct clusters, with the tantalizing possibility that one of them (BNS cluster) could be associated with BNSs and another (NSBH cluster) with NSBHs. As a proof of principle, assuming that all GRBs detected by Fermi/GBM and Swift/BAT associated with BNSs (NSBHs) lie in the BNS (NSBH) cluster, we estimate their rates (Gpc−3 yr−1). We compare these rates with corresponding BNS and NSBH rates estimated by the LIGO–Virgo–KAGRA (LVK) collaboration from the first three observing runs (O1, O2, O3). We find that the BNS rates are consistent with LVK’s rate estimates, assuming a uniform distribution of beaming fractions (f

Published: November 2024

Local and illegal exploitation of wildlife is particularly widespread in highly populated and bio-diverse countries such as India. In such countries, illicit utilization practices and how these are perceived among local communities are commonly not well-documented. Due to a lack of data, and environmental education measures to protect ecosystems and biodiversity, the extent of this exploitation appears immense and often goes unnoticed. Therefore, in 2019, a series of awareness workshops targeting the conservation of wildlife focused on monitor lizards (Varanidae) was conducted in five districts of West Bengal, India. The environmental awareness workshops were conducted through PowerPoint slide presentations and questionnaires collecting baseline data from the participants regarding their perceptions and relationships to the three species of Varanus recorded for West Bengal. Our findings reveal specific human attitudes and varying local utilization patterns of monitor lizards. This study was the first to communicate and spread awareness in the study areas about why the conservation of local wildlife such as Varanus species is important for ecosystems and human well-being based on the ‘Nature Contributions to People Concept’.

Jaguar populations (Panthera onca) on the Ecuadorian coast are critically endangered, with only a few dozen individuals remaining in the region. In some areas, no records have been documented for decades. Between November 2023 and January 2024, independent camera trap monitoring in northwestern Ecuador yielded evidence of the presence of a jaguar, marking a significant recovery after seven years of absence in Manduriacu and at least 15 years in Junín. The jaguar was observed moving through an area of approximately 25 km, traversing forested and human-altered zones. Furthermore, additional evidence from the Ecominga Foundation and the Cielo Verde community indicated the occurrence of livestock attacks, which aligns with the typical predatory patterns observed in jaguar behavior. The attack site was located approximately 8 km from where the jaguar was initially recorded, suggesting that both events refer to the same individual. In response, local authorities inspected the area and organized community workshops. Furthermore, an Andean bear was recorded in Manduriacu during the same sampling period, confirming the co-occurrence of both species in the area. The documented movement of this jaguar, along with the presence of other species, underscores the imperative need to continue research and conservation initiatives in the region. These initiatives will ensure the protection and coexistence of wildlife and human populations in this highly biodiverse region.

Published: November 2024

Accurate and effective landslide prediction and early detection of potential geological hazards are of great importance for landslide hazard prevention and control. However, due to the hidden, sudden, and uncertain nature of landslide disasters, traditional geological survey and investigation methods are time-consuming and laborious, and it is difficult to timely and accurately investigate and predict slope stability over a large area. Machine learning approaches provide an opportunity to address this limitation. Here, we present an intelligent slope stability assessment method based on a genetic algorithm optimization of random forest algorithm (GA-RF algorithm). Based on 80 sets of typical slope samples, weight (γ), slope height (H), pore pressure value (P), cohesion force (C), internal friction angle (φ) and slope inclination angle (°) were selected as characteristic variables for slope stability evaluation. Based on the GA-RF algorithm and incorporating 10-fold cross validation, a regression prediction model is trained on the training dataset, and then regression prediction is performed on the test dataset to verify the predictive performance of the model. The results indicate that the GA-RF prediction model has decent regression performance and has certain potential for slope stability analysis.
Approximation approach for backward stochastic Volterra integral equations
Authors: Yao Kutorzi Edwin , Samar Mahvish , Shi Yufeng
Published: November 2024

In this paper, we focus on studying a specific type of equations called backward stochastic Volterra integral equations (BSVIEs). Our approach to approximating an unknown function involved using collocation approximation. We used Newton's technique to solve a particular BSVIE by employing block pulse functions (BPFs) and the related stochastic operational matrix of integration. Additionally, we developed considerations for Lipschitz and linear growth, along with linearity conditions, to illustrate error and convergence analysis. We compared the solutions we obtain the values of exact and approximate solutions at selected points with a defined absolute error. The computations were performed using MATLAB R2018a.
Anticipation et adaptation : le ravitaillement des armées romaines pendant la Guerre d’Afrique (47-46 av. J.-C.)
Authors: Porte François
Published: November 2024

Les guerres civiles de la deuxième moitié du ier siècle av. J.-C. transposent les modèles logistiques romains à une échelle inédite où des armées mobilisent de la même manière les ressources d’un seul empire. La guerre d’Afrique (47-46 av. J.-C.) propose un tableau intéressant pour l’observation de l’anticipation des besoins et de la gestion de la logistique des armées romaines mais également des difficultés qui peuvent dangereusement compromettre cette organisation. Dans un premier temps, les troupes républicaines, implantées dans la province africaine depuis 49, en mobilisent les ressources de manière rationnelle, anticipant leurs besoins en prévision d’une offensive de César et mettant en place des lieux de stockage fortifiés et répartis sur le territoire. De son côté, César planifie avec soin une logistique appuyée sur sa base sicilienne et déployée sur les voies maritimes jusqu’en Afrique. Cependant, les difficultés liées à la navigation hivernale en diminuent grandement l’efficacité et le vainqueur de Pompée doit alors mettre en place une nouvelle organisation de son ravitaillement. Ces difficultés d’approvisionnement mettent en danger ses troupes, modifient ses plans et ont donc une influence déterminante sur ses décisions stratégiques. Si l’anticipation des besoins en nourriture des armées romaines constitue un élément central dans la préparation logistique des campagnes militaires, de nombreux aléas peuvent bouleverser cette organisation. La gestion de ces crises est alors déterminante pour la réussite des opérations et la capacité d’adaptation des généraux peut faire toute la différence.
Une médiation atypique de l’Histoire auprès du grand public : la création publicitaire et les spots pour U et PMU
Authors: Mercier Claire , Pampanay Elise
Published: November 2024

Par son omniprésence dans nos quotidiens, la publicité joue un rôle à part entière dans la culture de masse et devient au-delà de ses objectifs commerciaux un vecteur culturel original, notamment lorsqu’elle est amenée à utiliser l’Histoire pour illustrer ses messages. Par sa rhétorique de la synecdoque, elle nous offre dès lors un matériau peu étudié pour interroger quels fantômes et fantasmes elle emploie au-delà des stéréotypes et clichés qu’elle affectionne particulièrement. Afin de tenter de les identifier, nous proposons d’analyser deux publicités récentes, l’une pour Système U, qui met en avant la qualité des produits qu’elle distribue, et l’autre pour le PMU, qui vise à rajeunir l’image des paris hippiques. Notre choix a été motivé par l’utilisation peu fréquente de fresques historiques incluant l’Antiquité, cœur de notre objet d’étude. Nous chercherons d’abord à identifier les fantômes du passé formant un réseau de signes souvent tributaires d’une longue tradition de réception de l’Antiquité, puis nous nous interrogerons sur la vision fantasmée de cette période qu’ils véhiculent. Enfin nous verrons comment ces fantômes et fantasmes servent les objectifs persuasifs de la publicité tout en créant une forme populaire et atypique de médiation historique auprès du grand public.
Gods of Egypt (2016), un blockbuster mythographique
Authors: Cacace Nicolas
Published: November 2024

La communication étudie le blockbuster Gods of Egypt en tant que mythographie moderne des Aventures d’Horus et de Seth. Le conte originel est considéré comme un discours-objet dont il s’agit d’exposer les continuités et les trois grandes transformations animant sa réécriture scénaristique dans son nouveau contexte d’énonciation. Cette archéologie du mythe est pensée par la notion de transfert culturel du récit depuis le papyrus jusqu’à l’écran. Il ne s’agit pas d’une critique cinématographique, mais d’une analyse des dialogues et des images visant à interroger notre propre réception de l’Antiquité. Quelle place occupe l’héritage de la production du film ? ses impératifs de divertissement et de rentabilité ? nos grandes questions sociétales contemporaines ? notre rapport aux mythes et aux puissances divines ? Et que reste-t-il finalement de l’univers culturel pharaonique ? En filigrane, il s’agit d’étudier la pratique mythographique dans le blockbuster du xxie siècle.

Disparue, oubliée et de fait mal connue, comment la cite antique de Narbonne prend-elle forme dans l’espace muséal du Narbo Via ? Selon une double approche muséologique, en SIC et en histoire de l’art, nous interrogeons les gestes de figuration du passé (préfiguration, configuration et refiguration) au sein des modes de productions de l’exposition permanente (inaugurée en 2021) et de l’exposition temporaire Narbo Martius, Renaissance d’une capitale (2022). La démarche d’immersion sur plusieurs mois consécutifs avec relevé photographique et conduite d’entretiens compréhensifs auprès des concepteurs-muséologues rend compte des modalités de transpositions muséographiques, resituant, restituant ou encore reconstituant la ville de Narbonne, ainsi en voie de renaissance.
Reconstitution et patrimonialisation de l’éphémère et du mouvant. Le cas de la danse antique : enjeux, risques et paradoxes
Authors: Garelli Marie-Hélène
Published: November 2024

L’art chorégraphique a fait la preuve, depuis une vingtaine d’années, de sa capacité à faire évoluer les modalités de conservation et de mise en valeur de l’art dans les musées. Cette évolution passe notamment par une historicisation de la danse. La danse antique représente une composante importante de l’histoire culturelle de la danse que théoriciens et chorégraphes appellent de leurs vœux. L’histoire de la réception de la danse antique dans les siècles postérieurs et jusqu’à nos jours est celle d’une référence fondatrice, qui a légitimé ruptures et continuités artistiques et culturelles : reconstitutions, créations ou produits de la recherche-création. Du xvie au xviiie siècles, la notion d’héritage n’intervient guère dans le processus de réception de l’Antiquité chez les théoriciens et praticiens de la danse. Les textes antiques sur la danse (en particulier Lucien) viennent alimenter la réflexion théorique et les développements rhétoriques sur les formes contemporaines de cet art. L’idée d’héritage antique s’est formée avec les mouvements reconstructionniste et revivaliste de la fin du xixe et du début du xxe siècles, notamment aux États-Unis, en France et en Allemagne. L’iconographie (vases, bas-reliefs et peintures) justifie une revendication de continuité artistique et philosophique, un appel à une philosophie grecque du corps et, parallèlement, à l’archaïsme du geste et au mouvement non conceptualisé. Depuis la deuxième moitié du xxe siècle, les chorégraphes ont cessé de rechercher dans l’Antiquité une légitimation artistique. Les chorégraphes expérimentent, à travers cette période, la force du recours aux rites archaïques et la puissance émotionnelle de la danse collective. La recherche-création elle-même joue de l’écart avec une Antiquité qui reste pourtant très présente. Si la danse antique ne saurait être reconstruite, sa réception pourrait faire l’objet d’une patrimonialisation.

Published: November 2024

Background: Body shaming, a pervasive issue, has severe psychological and societal repercussions, particularly for early adolescents. This study addresses the gap in understanding body shaming in smaller urban settings such as Jember City, often overlooked in favour of larger metropolitan areas.Aim: The study aimed to investigate the psychological effects, trigger factors and potential preventive measures of body shaming among junior high school students in Jember City.Setting: The study was conducted in junior high schools in Jember City, East Java, Indonesia.Methods: An observational, cross-sectional design with both quantitative and qualitative approaches was used. Data were collected through self-administered questionnaires and in-depth interviews. The quantitative analysis was performed using the Spearman’s rank test.Results: The study included 320 adolescents aged between 12 and 15 years. Of these, 6.3% were 12 years old, 31.2% were 13, 31.6% were 14, and 30.9% were 15. Additionally, 56.2% of the participants were female. The majority (95%) identified as Muslim, and 72.8% had parents with bachelor’s degrees. Parental occupations ranged from private business to civil service. In terms of body mass index, 34.7% were classified as very thin, 18.1% as thin, 40.9% as normal, and 3.1% as fat or obese. Body shaming was widespread, with 73.1% criticized for their clothing, 59.9% for their speech, and 66.7% compared to others. The main sources of body shaming were family, peers, media, and personal insecurities. There was also a significant correlation between body shaming and stress (ρ = 0.404, p  0.01).Conclusion: Body shaming affects mental health, particularly among adolescents. It stems from societal norms and media perpetuation.Contribution: This study provides insights into body shaming in smaller urban settings, highlighting the need for targeted prevention efforts to mitigate its effects and promote healthier self-esteem and body image.

Authors: Annam Sharath Reddy , Krishna Anil , Seepana Lokanath , Papani Sridhar , Balaji R. , Premchand M
Published: November 2024

Chronic total occlusion (CTO) percutaneous coronary interventions (PCIs) have more complications due to the intrinsic complexity of the procedure which is further compounded by the ambiguity of the proximal cap. If the ambiguous proximal cap CTO is at the ostial left anterior descending (LAD) artery, the impact of complications is huge as the area of myocardium at risk is significant. Hence, while treating ambiguous proximal cap CTO at the ostial LAD artery or left circumflex artery, special attention must be given to prevent or minimize inflow injuries like dissection or intramural hematoma of the left main coronary artery and its branches. To prevent such complications, all the available CTO techniques need to be understood in this context and executed to keep procedural outcomes as predictable as possible. Intravascular ultrasound imaging is the passkey in wiring and detecting inflow injury to prevent intraprocedural catastrophes. This article explores the refinement and modification of existing techniques CTO PCI and the use of imaging in the context of ostial LAD CTO PCI.

Tachycardia-induced cardiomyopathy is defined as systolic and/or diastolic ventricular dysfunction resulting from a prolonged elevated heart rate which is reversible upon control of the arrhythmia or the heart rate. We describe a patient who had recurrent palpitations and breathlessness and had cardiomyopathy due to multiple arrhythmias. A systematic and meticulous electrophysiologic study could elucidate the mechanism of all the arrhythmias and successful ablation was done. Postsuccessful radiofrequency ablation, there was a resolution of ventricular dysfunction.
Approach to electrocardiographic diagnosis of narrow QRS tachycardia
Authors: Gurajala Venkatesh , Narayanan Kumar
Published: November 2024

Narrow QRS complex tachycardia (NCT) refers to a heart rate more than 100 bpm with a QRS duration of <120 ms. Most NCTs are supraventricular tachycardias (SVTs) with only rare instances of ventricular tachycardia. Understanding the mechanisms of SVT is crucial for the diagnosis and management. Regular NCTs include sinus tachycardia, atrioventricular (AV) nodal reentrant tachycardia, AV reentrant tachycardia atrial tachycardia (AT), and atrial flutter (AFL) with fixed conduction. Irregular NCTs encompass atrial fibrillation, AT, and AFL with variable AV block. Key features for analyzing NCT include the regularity of the rhythm, the relationship between P waves and QRS complexes, the RP interval, the morphology of the P wave, the mode of initiation and termination of the tachycardia, and the response to vagal maneuvers or adenosine. In this review, we outline a systematic approach to electrocardiogram diagnosis of the NCT.

Elderly patients presenting with metastatic, locally advanced breast cancer present a unique challenge in terms of management. This is especially so for patients aged 80 years and above with comorbidities, where it becomes difficult to offer any surgical or cytotoxic chemotherapy. This may lead to local disease progression if left unattended. Here, we present a case of a nonagenarian patient who presented with a large fungating growth in the breast associated with bleeding and foul smell. She could not be offered surgery or chemotherapy due to poor performance status. She was therefore treated with a 2-week hypofractionated radiation treatment protocol. Within 3 months after radiation, there was significant regression in breast mass, and all the ulcers healed with secondary intention. Few studies have reported the palliative role of hypofractionated radiotherapy for primary breast cancers with locally advanced disease. Radiation not just improves local control of disease; it profoundly relieves patients’ emotional distress associated with a fungating foul-smelling growth.
Reliability Prediction Using Additive Weibull Model

Published: November 2024

This paper presents additive Weibull reliability model using customer complaints
data and finite element fatigue (FEA) analysis data. Warranty data provides
insight into the underlying customer issues. Reliability engineers prepare a
prediction model based on this data to forecast the failure rate of components.
However, warranty data has certain limitations with respect to prediction
modeling. The warranty period covers only the infant mortality and useful life
zone of a bathtub curve. Thus, predicting with solely warranty data generally
cannot provide results with desired accuracy.

The failure rate of wear-out components is driven by random issues initially and
wear-out or usage-related issues at the end of the lifetime. For accurate
prediction of failure rate, data need to be explored at wear-out zone of a
bathtub curve. Higher cost always limits the testing of components until
failure, but FEA fatigue analysis can provide the failure rate behavior of a
part much beyond the warranty period without physical testing.

In this work, the authors proposed an additive Weibull model, which uses both
warranty and FEA fatigue life data for predicting failure rates. Prediction
model involves two data sets of a part: one with existing warranty claims and
other with fatigue life data. Hazard rate base Weibull estimation has been used
for modeling the warranty data whereas S-N curved-based Weibull parameter
estimation is used for FEA data. To separate Weibull models’ parameters, they
are first estimated and combined to form the proposed mix Weibull model.

OPTIMAL LQR CONTROL OF A PENDULUM BASED OVERHEAD CRANE USING THE WHALE OPTIMIZATION ALGORITHM
Authors:   Konya Technical University, Faculty of Engineering and Natural Sciences, Department of Mechanical Engineering, Konya, Turkey, Çakan Abdullah
Published: November 2024

This study represents an optimal LQR control approach to controlling the trolley movement of an overhead crane and sway reduction of its payload. The aim of the study is to improve the crane’s positioning accuracy and ensure smoother and safer operations with less swinging motion of payload. To achieve this, a Linear Quadratic Regulator (LQR) controller is proposed, which generates optimal control signal as input force. However, instead of manually tuning the LQR gains, The Whale Optimization Algorithm (WOA), a nature-inspired method that mimics the hunting behavior of whales, is used to tune control parameters. The results show that this LQR-WOA combination effectively improves the system’s stability, reducing oscillations efficiently and precisely the position of trolley. This approach offers a practical solution for industries where precise and safe overhead crane operation is essential.

The examination of the operational condition of axial piston pumps through the measurement of volumetric efficiency is a key aspect in assessing their performance and reliability. Volumetric efficiency is defined as the ratio of the actual flow rate of the pump to the theoretical flow rate and is directly influenced by internal losses due to leakage and compression. This parameter enables a detailed analysis of the condition of pump components, such as pistons, cylinder block, and valves, and indicates potential defects or the need for maintenance. The paper examines methods for measuring volumetric efficiency, as well as the impact of various operational conditions, including changes in pressure, fluid viscosity, and rotational speed. The aim of the research is to establish standards for assessing pump condition and to propose optimal methods for diagnostics and maintenance, with an emphasis on improving the durability and efficiency of axial piston pumps in various industrial applications.

Chip form is considered as important turning process performance measure. It is the prevalent criteria for the evaluation of industrial plastics machinability. Chips of unfavourable forms also create difficulties in production, such as stopping of the machine tool and damage to the machined surface. This factor is influenced by the cutting parameters in turning, which are the depth of cut, feed rate and cutting speed. This study focuses on the development of optimized support vector machine model for binary classification of chip forms in turning of commonly used industrial plastic, unreinforced polyoxymethylene copolymer POM-C.

Published: November 2024

Primary immunodeficiencies as a heterogeneous group of orphan diseases are of particular interest for the pharmaco-economical assessment of applied medical interventions due to diversity of their clinical presentation and complexity of standardizing approaches. In connection with increasing detectability due to neonatal screening and the potential for its expansion, it is increasingly important not only to treat, but to rehabilitate such patients as well in order to maintain a high quality of their lives, and therefore social and economic activity. The purpose of the research is a pharmaco-economical assessment of personalized bidirectional rehabilitation technology at the second stage in children with primary immunodeficiencies with the study of clinical and economic features of the method before including it in existing sources of financing for medical care. Materials and methods. A sample of patients from published data on evaluating the clinical component of the method was used based on determining the quality of life indicator. In this paper, data from calculations of direct expenses for providing care to one patient are used to calculate the costs as part of implementing the 2019-55-7 clinical approbation protocol. As an integral criterion of clinical and economic efficiency, QALY was calculated for one year of life, a pharmacoeconomical analysis of discounting at rates of 3 and 5%, a cost-effectiveness analysis, an incremental cost-effectiveness analysis, and a comparison of the results with the threshold of willingness to pay for the end of 2023 were carried out. Research results. The QALY for one year of life was 0.75. According to discounting results, since 2019, the amount of expenses has decreased from 603,071 to 452,303 rubles at the rate of 5% and up to 512 604 rubles at the rate of 3%. According to the results of the cost-effectiveness analysis, the cost of one unit of efficiency (QALY) in 2019 was 804,095 rubles, in 2024 – 683,480 rubles at the rate of 3% and 603,071 rubles at the rate of 5%. According to the results of the incremental cost-effectiveness analysis, the cost of one additional unit of efficiency (QALY) cost 6,884,372 rubles in 2019, in 2024 it is 5,851,716 rubles for the rate of 3% and 5,136,279 rubles for a 5% rate. Conclusions. When compared with the threshold of willingness to pay, the method is borderline acceptable. A significant factor contributing the most to the total cost of expenses is the cost of purchasing inventory. Additional criteria of clinical efficacy are required to recognize the method as pharmaco-economically effective. The transfer of catamnesis to the pre-rehabilitation stage, exclusion of provision with medicines at the second stage of rehabilitation at the expense of the medical organization's funds serve as ways to reduce the cost of the method.
