A Conformal Transformation Technique for Mapping an Open Channel Fluid Flow into a Two-Dimensional Plane
Authors: Ndiritu John Wahome 
Published: February 2025

Due to the emergence of many applications in areas of open-channel fluid flow, interest in this branch of fluid mechanics has increased considerably. These areas are wide-ranging, including electricity generation using tidal waves, control of floods and improvement of irrigation systems. Finance, thermal imaging, harnessing of melting of glaciers, flow of fluids over ramps and sluice gates, and quite notably, petroleum exploration are other areas where open channel flow mathematics find great relevance. Whether the free surface of the open channel is being predicted using known bottom characteristics (which is called the ‘direct approach’), or the bottom is being inferred from an observable surface (referred to as the ‘inverse approach’), researchers often find the need to make computations easier by transforming complex topologies into simpler, more relatable physical equivalents. In this paper, the channel flow of a gravity-influenced Newtonian fluid is treated as the physical plane. The fluid is flowing in the positive direction. The upper half-plane is conformally equivalent to the interior domain determined by any polygon, and the interior points of the physical plane are transformed to the corresponding points above the real axis of the upper half-plane which is then mapped onto the auxiliary half-plane, (the plane) by being treated as an infinite strip by use of the Schwarz-Christoffel theorem. Assumptions are made that the fluid has dimensional quantities such as uniform spee far upstream, and velocity potential . Far upstream before the arbitrary obstacle is encountered, the fluid has a uniform height, Then and are used to nondimensionalize the variables to enable computation in a completely non-dimensional environment. With the fluid assumed as steady, inviscid, irrotational and incompressible, w representing the physical w-plane, (and t) being points on the auxiliary the - plane, the angle made by a tangent to this plane at designated points, the required mapping is found to be .
Constructing an Alternative and Resisting Degeneration: The Case of a Multi-Stakeholder Cooperative in the Field of Regulated Professions
Authors: Arnaud Charlène , Château-Terrisse Pascale 
Published: February 2025

This research is rooted in the recently emerging stream of research on cooperative degeneration that acts as a counterpoint to the initial orthodox approaches and focuses on the processes, conditions, and practices that enable cooperatives to avoid degeneration. This research therefore analyzes a repertoire of practices that constitute an alternative organization and provides us with insight into the organization of work, coordination mechanisms, cooperative practices, and the rights and capacity for expression and decision-making of each individual within FINACOOP, a French multi-stakeholder accounting cooperative (SCIC – société coopérative d’intérêt collective). This makes it possible to assess under what conditions and how the SCIC studied maintains its alternative character, that is, combats the various dynamics of degeneration (of work, organization, and culture). Based on an atypical case study (FINACOOP is the only chartered accountancy firm operating under SCIC status in France), this research makes a significant contribution to the theory of degeneration by improving our understanding of the conditions for the establishment of this alternative that is distinctive in two ways: the fact that it operates within a regulated profession and its multi-stakeholder nature.
Comparación de la Efectividad entre el Sistema Vac Vs Aseo Quirúrgico + Parches Hidrocoloides en el Manejo de la Úlcera Sacra por Presión
Authors: Bautista Muñoa Jennifer , Ayón Aguilar Jorge , Pérez Chávez Gonzalo 
Published: February 2025

Antecedentes: Las úlceras por presión se consideran una de las lesiones cutáneas más prevalentes, sobre todo en personas de edad avanzada y dependientes. Las escaras, úlcera por decúbito o úlcera por presión, son lesiones de la piel, que puede llegar al tejido celular subcutáneo o músculo, provocada por presión, fricción, rozamiento prolongado, por lo general sobre una prominencia ósea. En el manejo de la úlcera por presión se debe considerar: valoración de los riesgos según escala elegida, valoración de la presencia de la lesión y la estatificación, clasificación inicial según estadios, descripción de la úlcera por presión, el alivio de presión sobre las superficies ósea, cambios posturales, medidas antiescaras, evitar la humedad o el exceso de calor, buen soporte nutricional. La Terapia de Presión Negativa se presenta como una de las mejores alternativas de tratamiento en los últimos años, debido a los múltiples beneficios que produce como la estimulación precoz del tejido de granulación. Objetivo: Comparar la efectividad entre sistema VAC vs aseo quirúrgico + parches hidrocoloides en el manejo de la úlcera sacra por presión. Material y métodos: Se realizó un estudio comparativo y longitudinal en el servicio de Cirugía General en el Hospital General de Zona Número 20 “La Margarita” IMSS, Puebla. Se incluyeron hombres y mujeres mayores de 18 años, con los siguientes criterios de inclusión: que ingresaran al servicio de Cirugía General con diagnóstico de úlcera sacra por presión, que ameritaran tratamiento intrahospitalario, candidatos a recibir tratamiento de su úlcera por presión, ya sea con sistema VAC o con aseos quirúrgicos + parches hidrocoloides. Se utilizó estadística descriptiva e inferencial por medio de análisis de X2 con una significancia estadística ≤0.05. Resultados: Se estudiaron 170 pacientes, 102 hombres y 68 mujeres. De los cuales, 93 pacientes fueron intervenidos quirúrgicamente para realización de aseo quirúrgico, ameritando hasta 2 o 3 intervenciones quirúrgicas durante su hospitalización vs 77 pacientes que fueron intervenidos quirúrgicamente para colocación de Sistema VAC, ameritando hasta 2 o 3 recambios. La comorbilidad más asociada fue Diabetes mellitus. La mediana de días de Estancia Intrahospitalaria del tratamiento quirúrgico fue de 10 (IQR 10) para aseo quirúrgico y parche coloide y de 7 (IQR 7) para colocación de sistema VAC. Conclusión: La efectividad del tratamiento de sistema VAC fue adecuada (7 días) si se compara con el tratamiento con aseo quirúrgico (>7 días).
La Praxis del Docente Universitario desde la Experiencia de Estudiantes con Autismo y Discapacidad Visual
Authors: Nassri Vargas Amanda Briseida , Martínez Martínez Janeth 
Published: February 2025

En el presente articulo: “La praxis del docente universitario desde la experiencia de estudiantes con Autismo y Discapacidad Visual”, tiene como propósito conocer el impacto que tuvieron los docentes en la trayectoria universitaria de estudiantes con autismo y/o discapacidad (en este caso discapacidad visual), a través de su formación, prácticas y estrategias que estos tuvieron a lo largo de su estancia por la institución. Bajo un enfoque cualitativo, con un diseño exploratorio- descriptivo y por medio del método biográfico, se recolectó la experiencia de tres estudiantes con estas condiciones en el Instituto de Ciencias Sociales y Administración de la Universidad Autónoma de Ciudad Juárez. Entre los hallazgos más destacables, se resalta la aún carente formación por parte de los docentes universitarios con respecto a las diversas condiciones, así como las limitadas estrategias didácticas con los que estos cuentan para la atención de estos grupos. Además, de la urgente necesidad de dotar a la comunidad universitaria de recursos que fomenten a espacios más inclusivos, donde impere la tolerancia, el respeto y la dignidad que la comunidad demanda, conviertiendose en una experiencia desafiante pero “llevadera” para estos estudiantes que cuentan con alguna condición.

Published: February 2025

Abstract
The SKYSURF project constrained extragalactic background light and diffuse light (DL) with the vast archive of Hubble Space Telescope (HST) images. Thermal emission from HST itself introduces an additional uncertain background and hinders accurate measurement of the DL level. Here, we use archival Wide Field Camera 3 (WFC3)/IR engineering data to investigate and model changes in the temperature of various components in HSTs optical path as a function of time (solar cycle) and time of the year (Earth–Sun distance). We also specifically investigate changes in temperature with HST's orbital phase and time since Earth occultation. We investigate possible correlations between HST component temperature and year, and temperature and month. The thermal background changes by less than one Kelvin in the WFC3 pickoff mirror, one of the most important contributors to the thermal background. We model these data to describe the impact that orbital phase, year, and time of year have on the HST and WFC3 component temperatures, and use this to derive the impact on the thermal dark signal and the resulting DL measurements. Based on this improved modeling, we provide new upper limits on the level of DL of 21, 32, and 25 nW m−2 sr−1 for F125W, F140W, and F160W. Additionally, by accounting for all known sources of measurement uncertainty, we report lower limits on the level of DL of 12, 20, and 2 nW m−2 sr−1 for F125W, F140W, and F160W.

Published: February 2025

Background
Potential benefits of enhancing nursing education using augmented reality (AR) invite further investigation of its applications. This study evaluated an AR system augmenting classes on complex cardiac problems in an undergraduate didactic nursing course.

Method

This study used a mixed-methods, quasiexperimental, and non-concurrent controlled design. Pre- and posttest scores for self-assessment quizzes and two examinations were compared for control group participants who received usual teaching (
n
= 51) and intervention group participants who received AR-enhanced teaching (
n
= 39).

Results
Usual teaching and the AR system were rated positively for realism, effectiveness, and usefulness by approximately 40% of the participants in both groups. The AR system had positive ratings for innovation, capturing interest, and engagement. Quiz and examination scores increased in both groups but were not significantly different between groups.

Conclusion

AR is an innovative approach promoting student engagement and interest in learning.

Understanding Nursing Backwards: The Evolution of Nursing as a Profession
Authors: Drevdahl Denise J. , Canales Mary K. 
Published: February 2025

Background
Becoming a profession, attaining professionalism, and transmitting a professional identity have been ongoing projects within nursing since the 1860s. To gain an understanding of nursing's attention on these three processes, the authors examined them from the context of self-regulation, a key hallmark of professionalism.

Method
Historical understandings of self-regulatory processes associated with nursing organizational representation, education standards, and regulatory requirements were traced. Mapping these understandings involved searching the literature and websites to outline historical events aligned with formation of professional nursing organizations for education, practice, and regulation, including accreditation and licensure.

Results
Past opportunities for nursing professional organizations to coordinate and collaborate with respect to self-regulation were missed such that fragmentation exists and persists within the discipline, with multiple organizations overseeing numerous professional and self-regulatory standards and processes.

Conclusion

Different paths need to be taken to create a future that better serves the discipline and meets its public obligations.

Protéger un paysage culturel évolutif vivant. Enjeux et contraintes dans le bassin minier du Nord-Pas-de-Calais, patrimoine mondial de l’Unesco
Authors: Mortelette Camille 
Published: February 2025

Œuvres conjuguées de l'être humain et de la nature, les paysages culturels expriment une longue et intime relation des peuples avec leur environnement » (article 1 de la convention Unesco, 1992). Même qualifiés d’évolutifs, ils ont vocation à être préservés afin d’être toujours significatifs de cette relation habitant-environnement. Néanmoins, ce lien est régulièrement considéré comme menacé. Dans le cas du bassin minier du Nord-Pas-de-Calais, ce sont notamment les formes urbaines récentes qui sont considérées comme fauteuses de troubles par les professionnels de l’aménagement. La présente contribution s’intéresse aux visions normatives et aux outils de la Mission Bassin Minier, en charge de la mise en œuvre du plan de gestion de l’inscription à l’Unesco, et les paradoxes relatifs au maintien de la valeur universelle et exceptionnelle d’un paysage culturel dit évolutif et vivant.
Nommer l’espace prussien (xiiie-xve siècles)
Authors: Gouguenheim Sylvain 
Published: February 2025

L’objectif de l’article est de repérer le lexique employé dans les documents émanant de l’ordre Teutonique en Prusse entre les xiiie et xive siècles. Ont été étudiés, dans une première approche qui demandera à être étoffée, l’ensemble des chartes et diplômes octroyés par les Teutoniques dans la période antérieure à 1309 (donations, partages de terres, règlements de petits litiges territoriaux, règlements administratifs). S’y ajoutent les rapports des visites des grands maîtres, les traités de paix ainsi que le traité d’arpentage, la Geometria culmensis de la fin du xive siècle.On observe une importante variété du vocabulaire dont la richesse ne doit pas induire en erreur : à des termes différents ne correspondent pas nécessairement des réalités différentes. On constate aussi un vif souci de précision dans les délimitations, quelle que soit l’importance des terres concernées. On remarque en outre que la plupart des limites fixées sont linéaires, même s’il faut distinguer les « frontières sèches » (déplaçables) des « frontières humides » (aléatoires, d’où l’importance de déterminer avec précision les rives du fleuve en temps « normal », c’est-à-dire hors de toute période de crue). L’espace prussien fut donc délimité et – à défaut, semble-t-il, d’avoir été cartographié – pensé comme continu, homogène et mesurable.
Management of Delayed Vascular Complications of Gunshot Wounds Following Peripheral Vascular Trauma – A Case Series of Five Patients and Institutional Experience
Authors: Praveena Madavan , Singh Devender , Aryala Shalini 
Published: February 2025

Abstract

Objectives:
To describe the different presentations, evaluations, management and outcome of delayed vascular complications of gun shot wound following peripheral vascular trauma.

Materials:
A retrospective study of three years from January 2021 to December 2023. All the patients with peripheral vascular injuries following gun shot wound missed at the time of causative trauma were included. Patients with acute presentations were excluded. All the cases were evaluated with CT angiography and managed with various open vascular surgical techniques and their results were assessed.

Results:
Five patients with delayed vascular complications following gun shot wounds underwent vascular repairs. Age ranged from 25 - 40 yrs. One female and four were males. The time interval between injury and presentation ranged from 10 to 15 years. All the patients presented with high flow Arterio -venous fistula with extensive limb swelling. Also associated with giant venous aneurysms in three, nonhealing ulcers with venous hypertension in three and limb ischemia in one. Lower limb vessels were affected in 4 cases and upper limb in 1. Superficial femoral and popliteal arteries were more frequently involved. Ligation and excision of high flow a-v fistula with vein bypass was performed in all. In cases with giant venous aneurysm, tangential excision with lateral venorraphy was done. Postoperatively all the patients were on anticoagulation. Follow up showed good recovery.

Conclusions:
High flow A-V fistula is the commonest delayed presentation with extensive limb swelling following gun shot wound injury. In most cases it was found to be associated with giant venous aneurysms and venous hypertension. Open vascular surgical procedures provides durable long term results and should be considered as the first choice in these young patients.
Successful Management of Splenic Artery Aneurysm by Coil Embolization in a Postpartum Woman
Authors: Gowda Ganesh G , Prabhuswamy Nandeesh Hosur , Tigga Maureen Prativa 
Published: February 2025

Abstract
Splenic artery aneurysm (SAA) rupture can be catastrophic and in the peripartum setting is associated with high maternal and fetal morbidity and mortality. Timely diagnosis, however, and appropriate referral for management whether surgical or endovascular have favorable outcomes. The present case describes a timely and successful management of an SAA in a postpartum patient treated with endovascular coil embolization. Learning Points: (1) SAA is rare but has a strong association with pregnancy, puerperium, and multiparity, therefore clinicians should consider its possibility while treating this population. (2) Ruptured SAA can be fatal therefore suspicion or identification of a SAA must be done in a timely manner.
Evaluation of Outcomes in Patients Undergoing Major Vascular Procedures (Operative and Interventional): A Prospective Cohort Study
Authors: Yadav Rajeshwar , Sharma Aditya , Pathak Swati 
Published: February 2025

Abstract

Introduction:
Vascular procedures are known to cause postoperative cardiac complications. This study aims to evaluate the outcomes in terms of complications following 1 year after vascular surgery and to evaluate an association between myocardial injury after noncardiac surgery (MINS) and 1-year mortality.

Materials and Methods:
The prospective cohort study was conducted for 18 months, and the screening of eligible patients was performed every day from the list of patients fulfilling the inclusion criteria. The study patients were observed during their hospital stay for the occurrence of the study outcomes and recorded laboratory results as well as anesthesia and discharge data. Using SPSS version 20, descriptive statistics were utilized to provide an overview of the study cohort’s baseline characteristics and the prevalence rate of MINS.

Results:
A total of 56 patients were enrolled in the study, and 13 (30.2%) of them were lost to follow-up; patients were followed up for a year after surgery. Six (13.9%; 95% confidence interval) patients had a diagnosis of myocardial damage following noncardiac surgery. MINS was more pronounced in the patients above 80 years of age group, i.e., 3 (30%), while it was 2 (14.3%) in the 60–80 years of age group and 1 (5.7%) in the age group of <60 years. The frequency of MINS in our study among the patients who underwent noncardiac surgeries was 33.3% of patients who underwent vascular surgeries in the head-and-neck region, 11.1% had surgery on vessels in relation to the abdominal cavity, and 10% had surgery in vasculature related to the upper and lower extremities. In patients who received postoperative aspirin, no mortalities were observed. Similarly, among 22 patients who did not receive clopidogrel postoperatively, 1-year mortality was significantly (p <0 .01) associated with MINS.

Conclusion:
MINS is prevalent and linked to unfavorable short- and long-term consequences. The demographics and comorbidities of the surgical population, as well as the method and time of troponin testing, all influence the occurrence of MINS. While there may be many preventive measures to lower cardiovascular risk following a diagnosis of MINS, the most effective measures under such circumstances remain unclear. The patient’s cardiovascular risks distinctive to the surgery will need to be carefully and individually assessed with a very high level of suspicion to obtain optimum outcomes following such procedures.
