Abstract The present text is inscribed as a reconstruction of an ethnographic process related to the self-understanding perspective and a socio-educational epistemology. The research contributes to understanding the singularity school called Escuela Albergue. The article considers the world as a constant interpretation, which is presented in the corpus as a narrative inflection, of an evocative nature consistent with the meaning of the epistemological proposal. Focuses on autobiography as a condition for an ethnographic narrative that suggests analogical hermeneutics and its intertwined components as language toward essayistic gestures. It presents some social dimensions of the construct Escuela Albergue as an ethnographic research process in an interpretative key in dialogue with epistemologies of the psychology of affectivity. The narration thus conceived, is presented as an aesthetic experience articulated to the web of possibilities of ethnographic research. The gaze is located in a biographical condition, interpretable as an understanding of the world and its questions as a fusion of horizons, writing as a question of reading, and ethnography as a narrative character. It ends by reflecting on ethnographic work as a living archive.

Resumen El presente texto se inscribe como una reconstrucción de un proceso etnográfico en clave de autocomprensión que, respondiendo a una epistemología socioeducativa, sitúa la investigación como un aporte a una singularidad escolar denominada Escuela Albergue. El artículo esboza algunas interrogantes al objeto que fue construido, considerando al mundo como una constante interpretación, que es presentada en el corpus como una inflexión narrativa, de carácter evocativo coherente con el sentido de la propuesta epistemológica. Focaliza en la autobiografía como condición para una narrativa etnográfica que sugiere a la hermenéutica analógica y sus componentes entramados como lenguaje hacia una gestualidad ensayística. Presenta algunas dimensiones sociales del constructo Escuela Albergue como proceso de investigación etnográfica en clave interpretativa en diálogo con epistemologías de la psicología de la afectividad. La narración así concebida se muestra como una experiencia estética articulada a la trama de posibilidades de la investigación etnográfica. Condición biográfica desde donde la mirada se sitúa, interpretable como comprensión del mundo y sus interrogantes en tanto fusión de horizontes; la escritura como interpelación de la lectura y la etnografía como carácter narrativo. Termina reflexionando respecto al trabajo etnográfico como archivo vivo.

Autonomous electric vehicles use camera sensors for vision-based steering control and detecting both roads and objects. In this study, road and object detection are combined, utilizing the YOLOv8x-seg model trained for 200 epochs, achieving the lowest segmentation loss at 0.53182. Simulation tests demonstrate accurate road and object detection, effective object distance measurement, and real-time road identification for steering control, successfully keeping the vehicle on track with an average object distance measurement error of 2.245 m. Route planning for autonomous vehicles is crucial, and the A-Star algorithm is employed to find the optimal route. In real-time tests, when an obstacle is placed between nodes 6 and 7, the A-Star algorithm can reroute from the original path (5, 6, 7, 27, and 28) to a new path (5, 6, 9, 27, and 28). This study demonstrates the vital role of sensor fusion in autonomous vehicles by integrating various sensors. This study focuses on sensor fusion for object-road detection and path planning using the A* algorithm. Real-time tests in two different scenarios demonstrate the successful integration of sensor fusion, enabling the vehicle to follow planned routes. However, some route nodes remain unreachable, requiring occasional driver intervention. These results demonstrate the feasibility of sensor fusion with diverse tasks in third-level autonomous vehicles.

RESUMEN La subluxación atlantoaxial es la lesión más frecuente en la columna cervical causada por la artritis reumatoidea. Se manifiesta por rigidez de nuca, dolor cervical y déficit neurológico. El diagnóstico se realiza con tomografía computarizada e imágenes de resonancia magnética. El intervalo atlanto dental anterior mayor a 5mm indica inestabilidad atlantoaxial, el intervalo atlanto dental posterior menor a 14mm advierte riesgo neurológico. Las indicaciones más frecuentes de cirugía son: dolor cervical severo, inestabilidad y síntomas de mielopatía. Cuando existe compresión medular es necesaria la descompresión cervical alta sea por vía posterior o por vía anterior (odontoidectomía endonasal versus transoral). La línea rinopalatina nos indicará la factibilidad de una odontoidectomía endonasal endoscópica (OEE). El objetivo de la presentación del presente caso es compartir nuestra experiencia con la primera odontoidectomía endonasal endoscópica realizada en nuestro país y fomentar la utilización de la técnica. La cirugía fue realizada en un paciente con cuadriparesia espástica por subluxación atlantoaxial por artritis reumatoidea y que presentó excelente evolución pos operatoria, con recuperación casi completa. La OEE es una técnica operatoria mínimamente invasiva, ideal para pacientes con múltiples comorbilidades y que ofrece de buenos a excelentes resultados.

ABSTRACT Atlantoaxial subluxation is the most common injury to the cervical spine caused by rheumatoid arthritis. It is manifested by neck stiffness, neck pain and neurological deficit. Diagnosis is made with computed tomography and magnetic resonance imaging. The anterior dental atlanto interval greater than 5mm indicates atlantoaxial instability, the posterior dental atlanto interval less than 14mm warns of neurological risk. The most frequent indications for surgery are: severe neck pain, instability and symptoms of myelopathy. When there is spinal cord compression, upper cervical decompression is necessary, either via a posterior or anterior approach (endonasal versus transoral odontoidectomy). The rhinopalatine line will indicate the feasibility of an endoscopic endonasal odontoidectomy (EEO). The objective of the presentation of this case is to share our experience with the first endoscopic endonasal odontoidectomy performed in our country and to promote the use of the technique. The surgery was performed on a patient with spastic quadriparesis due to atlantoaxial subluxation due to rheumatoid arthritis and who presented excellent postoperative evolution, with almost complete recovery. EEO is a minimally invasive surgical technique, ideal for patients with multiple comorbidities and offering good to excellent results.

ABSTRACT Purpose: To evaluate the effectiveness of mapping-targeted biopsies (MTB) on the index lesion for the detection of clinically significant prostate cancer (csPCa) in transperineal fusion-image prostate biopsies. Materials and Methods: A retrospective analysis was conducted on 309 men with suspected PCa who underwent prostate biopsies at the Creu Blanca reference center in Barcelona, Spain. The Prostate Imaging-Reporting and Data System (PI-RADS v.2.1) of the magnetic resonance images (MRI) were reclassified by an expert radiologist reading of pre-biopsy biparametric MRI used for segmentation of suspected lesions. Transperineal MTB of suspicious lesions and 12-core systematic biopsies were performed using the Artemis™ platform. CsPCa was defined as International Society of Urological Pathology grade group ≥ 2. Results: CsPCa was detected in 192 men (62.1%), with detection rates of 6.3% for PI-RADS 2, 26.8% for PI-RADS 3, 87.3% for PI-RADS 4, and 93.1% for PI-RADS 5. MTB of the index lesion identified 185 csPCa (96.3%). CsPCa was detected solely in systematic biopsies in three cases (1.6%), while an additional four cases (2.1%) were identified only in the second suspected lesion. A predictive model for csPCa detection in MTB of the index lesion was developed, with an AUC of 0.918 (95% CI 0.887-0.950). Conclusions: This model had the potential to avoid 23.3% of prostate biopsies without missing additional csPCa cases. MTB of the index lesion was highly effective for identifying csPCa in fusion transperineal prostate biopsies. A developed predictive model successfully reduced the need for almost one quarter of biopsies without missing csPCa cases.

Abstract: In elastic stable intramedullary nailing (ESIN), there are different opinions among surgeons on whether to leave the nail buried in the same arm or to leave it exposed. Objective: To determine the risk of re-fracture in patients with a nail buried directly into the amr or left exposed as a treatment for forearm fractures, and to investigate postoperative complications. Patients and Method: The study included 113 pediatric patients with a forearm fracture of both diaphyses. Two groups were formed according to whether the nail was buried (Group B, n: 53) in the same arm or left exposed (Group E, n: 60). Data on the number of open reductions, the time to nail removal, the anesthesia type used for its removal, the number of re-fractures, skin infection, and nail entry site irritation were analyzed. Results: The mean union times between the groups were not significantly different (P = 0.371). The mean time of nail removal in group B (16.02 ± 1.29 weeks) was significantly longer than that of group E (6.65 ± 0.95 weeks) (P < 0.001). Open reduction rates were similar between groups (P = 0.401). The general anesthesia rate for nail removal in group B (77.4%) was significantly higher than group E (11.7%) (P < 0.001). The re-fracture rate was higher in patients who underwent open reduction in both groups (P < 0.001). Conclusion: The results of this study demonstrated that, despite the increased infection rate, leaving the nail exposed did not increase the re-fracture rate, which was associated with open reduction.

Resumen: En el uso de clavos intramedulares elásticos estables (ESIN) existen diferentes opiniones entre los cirujanos sobre dejar el clavo introducido en el mismo brazo o bien dejarlo expuesto. Objetivo: Determinar el riesgo de re-fractura en pacientes con clavo introducido directamente en el brazo o expuesto como tratamiento de las fracturas de antebrazo, e investigar las complicaciones postoperatorias. Pacientes y Método: El estudio incluyó un total de 113 pacientes pediátricos con fractura de ambas diáfisis del antebrazo. Se formaron dos grupos en función del dispositivo introducido en el mismo brazo (Grupo B, n: 53) o dejado al descubierto (Grupo E, n: 60). Se realizaron análisis con respecto al número de reducciones abiertas, el tiempo transcurrido hasta la retirada del implante, el tipo de anestesia utilizado para esta ocasión, el número de refracturas, la infección cutánea y la irritación del lugar de entrada del clavo. Resultados: Los tiempos promedio de fusión entre los grupos no fueron muy diferentes (P = 0,371). El tiempo promedio de retirada del implante en el grupo B (16,02 ± 1,29 sem) fue muy superior en comparación con el del grupo E (6,65 ± 0,95 sem) (P < 0,001). Las tasas de reducción de aperturas fueron similares entre los grupos (P = 0,401). La tasa de anestesia general para la extracción de implantes en el grupo B (77,4%) fue muy superior a la del grupo E (11,7%) (P < 0,001). La tasa de refractura fue mayor en los pacientes sometidos a reducción abierta en ambos grupos (P < 0,001). Conclusión: Los resultados de este estudio demostraron que, a pesar de la mayor tasa de infección, dejar el clavo expuesto no aumentaba la tasa de refractura, que se veía más asociada a la reducción abierta.

Abstracts Non-soluble particlestrapped in natural ice (glaciers, permafrost, hail) provide valuable information about the envi-ronments in which they were formed. The extraction of the particles is usually carried out through the melting of ice and subsequent filtering of the water obtained. Here, a novel methodology for extracting ice particles from the solid phase is presented, which is efficient, lowcost in infrastructure, and minimizes possible sources of contamination. This methodology of adapted sublimation particle separation allows to determine the spatial distribution and concentration of non-soluble particles, as well as their sizes (without the limitations of filtration), their shape, structure and elemental chemical composition. The method is in this case applied to hail collected during the program COSECHEROS, which has a medium-sized particle of 40 pm at its center.

Resumen Las partículas no solubles atrapadas en los hielos naturales (glaciares, permafrost, granizos, etc.) dan información valiosa sobre los ambientes en los que se formaron. La extracción de las partículas habitualmente se realiza a través de la fusión del hielo y el filtrado posterior del agua obtenida. Aquí se presenta una metodología novedosa de extracción de partículas del hielo desde la fase sólida, que resulta eficiente, de bajo costo en infraestructura y que minimiza las posibles fuentes de contaminación. Esta metodología de separación de partículas por sublimación adaptada, permite determinar la distribución espacial y la concentración de partículas, así como sus tamaños (sin las limitaciones de las filtraciones), la forma, estructura y composición química elemental de las mismas. El método se aplica a un granizo recolectado durante el programa COSECHEROS, el cual tiene en su centro una partícula de tamaño mediano de 40 pm.

This study examined an alternative technique of extracting tungsten from wolframite ore using a fusion method with ammonium phosphate salt. Current techniques use alkali salts to decompose tungsten ores and use various purification methods to produce ammonium paratungstate, which is a key intermediate precursor in the extraction of tungsten. In this study, a two-step extraction process, which involves thermal decomposition of the ore using fusion and a separation stage, is examined. The novelty of this technique is the ability to completely decompose wolframite ore and form an unstable tungsten oxide phosphate (WO2(PO3)2) compound. The instability of WO2(PO3)2 in deionized water enables selective isolation of tungsten as insoluble precipitates of WO3 and WO2. The decomposition reaction of WO2(PO3)2 is influenced by the presence of oxygen and determined to be first order under ambient conditions. Scanning electron micrographs and X-ray diffraction analysis showed above 80% of the tungsten precipitated compared with the amount that remained in the filtrate solution.

Abstract Additive manufacturing has evolved from a rapid prototyping technology to a technology with the ability to produce highly complex parts with superior mechanical properties than those obtained conventionally. The processing of metallic powders by means of a laser makes it possible to process any type of alloy and even metal matrix composites. The present work analyzes the tensile and compressive response of 316L stainless steel processed by laser-based powder bed fusion. The resulting microstructure was evaluated by optical microscopy. Regarding the mechanical properties, the yield strength, ultimate tensile strength, percentage of elongation before breakage, compressive strength and microhardness were determined. The results show that the microstructure is constituted by stacked micro molten pools, within which cellular sub-grains are formed due to the high thermal gradient and solidification rate. The compressive strength (1511.88 ± 9.22 MPa) is higher than the tensile strength (634.80 ± 11.62 MPa). This difference is mainly associated with strain hardening and the presence of residual stresses. The initial microhardness was 206.24 ± 11.96 HV; after the compression test, the hardness increased by 23%.

Resumen La fabricación aditiva ha evolucionado desde una tecnología de prototipado rápido hasta una con la capacidad de producir piezas altamente complejas con propiedades mecánicas que superan las logradas de manera convencional. El procesamiento de polvos metálicos mediante tecnología láser permite el tratamiento de una amplia gama de aleaciones e incluso materiales compuestos. Este estudio analiza la respuesta a tracción y compresión del acero inoxidable 316L fusionado mediante fusión selectiva láser. La microestructura resultante fue analizada mediante microscopía óptica. En cuanto a las propiedades mecánicas, se determinaron la resistencia a la fluencia, la resistencia última a la tracción, el porcentaje de elongación antes de la fractura, la resistencia a la compresión y la microdureza. Los resultados muestran que la microestructura está compuesta por micropiletas fundidas apiladas, dentro de las cuales se generan subgranos celulares debido al alto gradiente térmico y la alta velocidad de solidificación. La resistencia a la compresión (1511.88 ± 9.22 MPa) es superior a la resistencia a tracción (634.80 ± 11.62 MPa). Esta diferencia está principalmente asociada con el endurecimiento por deformación y las tensiones residuales. La microdureza inicial fue de 206.24 ± 11.96 HV, y después de la prueba de compresión, la dureza aumentó en un 23 %.

Abstract Adolescent idiopathic scoliosis is considered the most severe and common spinal deformity, affecting children and adolescents still in the neuropsychomotor development phase before they reach skeletal maturity. This study aimed to evaluate the surgical approach to adolescent idiopathic scoliosis (AIS), considering the results associated with the reduction of pathological curvature, pulmonary function, and repercussions on the quality of life of adolescents undergoing such treatment. Systematic literature review, with a quantitative and qualitative approach to the data collected, structured according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), carried out in the databases linked to the Medical Literature Analysis and Retrieval System Online (MEDLINE) and Latin American and Caribbean Health Sciences Literature (LILACS). The total sample of the studies was 638 adolescents with AIS, with a mean age of 14.93 years ± 1.24. The mean correction of the main pathological curvature in the studies was 55.06% ± 12.24. In all of the selected studies using posterior spinal fusion to correct AIS, there was a significant reduction in pathological curvatures (> 49%), and the recurrence of curvature in none of the studies exceeded a pathological gain of more than 5%. As for lung function, the studies showed significant increases in forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) in patients with severe AIS, and no pulmonary function losses were reported after surgery to correct AIS. deformity maturity AIS , (AIS) treatment review collected MetaAnalyses Meta Analyses PRISMA, PRISMA (PRISMA) MEDLINE (MEDLINE LILACS.

Resumo: O objetivo deste artigo é analisar como as tecnologias digitais implicam na con-fusão de sujeitos e objetos no campo das imagens. Para isso, partimos da distinção feita por Lucien Sfez entre comunicação representativa e expressiva, e como pode ser notada uma tendência à sua confusão de uma forma que o autor chamou de “tautismo”. A tese sustentada é que este tautismo - conceito considerado problemático - é atualmente uma confusão de sujeitos e objetos no campo das imagens digitais. Assim, as imagens são consideradas terceiros, que mediam entre sujeitos e objetos, gerando continuidade entre eles, mas sem confundi-los. Posteriormente, o cinema expandido, o escaneamento 3D, as imagens de síntese e a arquitetura discreta das imagens digitais são analisados e reunidos na noção de simulacro. Conclui-se que nenhuma imagem pode existir em si mesma sem sua conexão com sujeitos e objetos, embora a imagem digital tenha uma tendência a escondê-lo

Resumen: El objetivo del presente artículo es analizar cómo las tecnologías digitales implican la con-fusión de sujetos y objetos en el campo de las imágenes. Para ello se parte de la distinción realizada por Lucien Sfez entre comunicación representativa y expresiva, y cómo puede notarse una tendencia a su confusión en una forma que el autor llamó “tautismo”. La tesis sostenida es que ese tautismo -concepto considerado problemático- es en la actualidad una con-fusión de sujetos y objetos en el campo de las imágenes digitales. Así, se considera a las imágenes como terceros que median entre sujetos y objetos, generando continuidad entre ellos, pero sin confundirlos. Posteriormente, el cine expandido, el escaneo 3D, las imágenes de síntesis y la propia arquitectura discreta de las imágenes digitales son analizados y reunidos en la noción de simulacro. Se concluye que ninguna imagen puede existir en sí misma sin su conexión con sujetos y objetos, aunque la imagen digital tienda a ocultarlo

Abstract: The aim of this article is to analyze how digital technologies imply the confusion of subjects and objects in the field of images. It starts from the distinction made by Lucien Sfez between representative and expressive communication, and how there is a tendency towards their confusion in a form that the author called "tautism". The thesis argued is that this tautism -a concept which we consider problematic- is currently a con-fusion of subjects and objects in the field of digital images. Thus, images are considered as third parties that mediate between subjects and objects, generating continuity between them, but without confusing them. Subsequently, expanded cinema, 3D scanning, synthetic images, and the discrete architecture of digital images themselves are analyzed and gathered under the notion of simulation. It is concluded that no image can exist on its own without its connection to subjects and objects, although the digital image tends to conceal it

IrO2 is a current state-of-the-art catalyst for polymer electrolyte membrane water electrolyser (PEMWE) applications due to its high stability during the oxygen evolution reaction (OER). However, its activity needs to be significantly improved to justify the use of such a high-cost material. In this study, the activity of the IrO2 catalyst was improved by optimising and comparing two synthesis methods: the modified Adams fusion method (MAFM) and the molten salt method (MSM). Optimum OER performances of the IrO2 catalysts synthesised with the two synthesis methods were obtained at different temperatures. For the MAFM, a synthesis temperature of 350 °C produced the IrO2 catalyst with an overpotential of 279 mV and the highest OER stability of ~82 h at 10 mAcm-2. However, for the MSM, the lowest overpotential of 271 mV was observed for IrO2 synthesised at 350 °C, while the highest stability of ~75 h was obtained for the IrO2 synthesised at 500 °C. SIGNIFICANCE: IrO2 is still currently a state-of-the-art catalyst in PEMWE due to its high stability in the highly acidic and oxidising conditions of the OER. High-performance IrO2 catalysts were successfully produced via the MAFM and MSM. Both the MAFM and MSM are simple and easily scalable for high-volume production of metal oxide catalysts. This study showed that the physical/structural properties of the IrO2 catalysts can be tailored through synthesis methods and synthesis conditions to improve their OER performance.

ABSTRACT This text explores different socio-historical and theoretical contents that shape the current experiences of women who live in the territories of what is known today as the north of Chile. The objective is to contribute to the theoretical approach in the analysis of social and gender inequalities in a context marked by mining extractivism and the vulnerability of its inhabitants. From a gender perspective, we analyze extractivism in the area and its consequences beyond environmental issues. The main conclusion is that the intersection of the issues addressed requires complex analyses where they can converge to strengthen the fusion of issues with a denouncing and innovative perspective. sociohistorical socio historical Chile inhabitants perspective

ABSTRACT Introduction: The balance of materials in obtaining the G-0 intermediate product guarantees that the product is consistently produced and controlled. Objective: Carry out the material balances in the mechanical and thermal operations in obtaining the intermediate product G-0. Materials and Methods: The analysis of the input and output materials mass was conducted for the crude G-0 centrifugation systems, filtration of the suspension to be purified from crude G-0, and centrifugation and drying of the PI G-0. The composition was determined using available techniques and previous research work. For the calculation of the average results of the streams with the Microsoft Office Excel® program 25 batches produced in the years 2016, 2017, 2018 and 2019 were taken into account. Results and Discussion: The material balances per batch in the obtaining of PI G-0 in the systems Centrifugation G-0 Crude, Centrifugation of PI G-0, Filtration and Drying allowed to know the real yield of the desired product for 14 moles of furfural and the losses in the residual streams and due to manufacturing. In the drying operation, the removal of water and wet and dry base solvent was quantified. Conclusions: The material balances in the mechanical and thermal operations of the process of obtaining the intermediate product G-0 allow assuring the consistency of the process. The tests carried out on the specifications: organoleptic characteristics, identification by UV VIS ultraphotometry, melting interval and purity of the product declare the conformity for its use in the production of Furvina.
