Fem matemàtiques treballant amb els nombres primers

L'estudi dels nombres primers ha apassionat a molts matemàtics, i no matemàtics, de tots els temps. Al llarg d'aquesta notes1, amb l'objectiu de contagiar-nos una mica d'aquest apassionament, ens anirem plantejant preguntes i cercant respostes sobre diferents aspectes dels nombres primers. I com l'essència de l'activitat matemàtica consisteix justament en saber fer-se preguntes i buscar-hi respostes, podem dir que "farem matemàtiques treballant amb els nombres primers"

Transgender College Student Equity and Inclusion Program

Understanding the inequities experienced by Transgender college students on university campuses is fundamental to promoting the occupational engagement of Transgender individuals. The Transgender community in the United States (U.S.) today is more widely varied and accepted than ever before in the recorded history of post-European colonialization of this country (Beemyn, 2014). Dowers, White, Kingsley and Swenson (2019) explain the risk for increased occupational injustice for Transgender college students due to their complex experience of occupations and the influencing factors. Current research has significant gaps in our understanding of how to counteract the effects of occupational injustice for Transgender college and university students. This project analyzes the needs and experiences of Transgender students and utilizes them to synthesize a program to promote occupational and educational equity. This program focuses on creating equitable and inclusive university campuses by providing suggestions on how to eradicate systemic transphobia and increase education and awareness of Transgender student needs. A mixed-method project design was utilized as a needs assessment, which included quantitative and qualitative data collection via anonymous surveys with both Likert scale ratings and short answer questions. Three themes emerged from the findings: existing Transgender resources, systemic transphobia, and physical and psychosocial environment. Needs assessment findings were developed into a ten-section Transgender Student Equity and Inclusion Program which is being implemented at Dominican University of California

Virtual reconstruction in bim technology and digital inventories of heritage

The documentation of the architectural heritage requires the storage of large amounts of information that must be stored and processed in very different formats, since it comes from experts from different areas of knowledge. This heterogeneity of information makes communication difficult among professionals who participate in documentation work, such as restorers, architects, engineers, archaeologists or historians, with the transfer of information being one of the biggest problems to be solved, through the creation of a methodology that favors the diffusion and accessibility to the materials coming from the investigation. The aim of the study is to create a protocol or methodology, to create a graphic database that allows the inventory of the architectural heritage in Aragon. The solution implies the development of a geometric model that allows to include and relate information related to it. The format is a HBIM model capable of incorporating information on a stratified support, with visualization, documentation and management capabilities that allow a complete view of the building to be cataloged, incorporating useful information for its conservation, restoration, protection and dissemination, as well as interoperability between tools and other systems throughout the entire life cycle of the object. In this research, we will work with the virtual platform Petrobim, a tool composed of a database and a viewer, whose purpose is the management and query of information linked to a 3D model, throughout the entire cycle building life

3D survey and virtual reconstruction of heritage. The case study of the City Council and Lonja of Alcañiz

[EN] With current data acquisition techniques, exhaustive documentation of patrimonial goods is generated, which allows obtaining a 3D geometric model, on which data from research from research is generated. As in other fields of architecture, the latest graphic techniques and manipulation of the image, allow a working methodology other than the current one in the patrimonial field. The information systems have been evolving towards technologies developed with open source software, the use of standards, ontologies and the structuring of information and of the 3D model itself under a semantic hierarchy. Interoperability between databases is favored and the maintenance of applications is ensured. The purpose is to support decision-making related to the model and simultaneously, serve multiple purposes such as cataloging, protection, restoration, conservation, maintenance or dissemination, among others. The research carried out for the realization of the survey of the City Council and Lonja of Alcañiz (Teruel), has the aim of expanding the historical knowledge of the buildings and delimiting its possible constructive phases, in order to obtain the geometric reality of the buildings. In this way, provide greater instruments to carry out the drafting work of the set restoration project. Quintilla Castán, M.; Agustín Hernández, L.

Generation of a digital archive of heritage, with drones in rural areas

The enhancement of heritage, both cultural and natural, must be considered as a resource for revitalizing the territory. In this context, Aragon has a great landscape and cultural heritage that is scattered throughout the territory and is not very accessible. It needs to be properly documented and inventoried as a means of activating new processes of knowledge, enhancement and use of rural development. This work is devoted to the creation of the Digital 3D Inventory of the Aragonese Mudejar Architectural Heritage, which includes buildings that currently have little graphic and imprecise documentation, since many of them are located in small towns of less than 500 inhabitants, with urban fabric of narrow streets. To carry out the registration, the use of drones to capture images and later the construction of the point cloud with photogrammetry, it is an adequate technical and economically sustainable solution since it deals with populations plagued by depopulation and with few resources. A generalized methodology is proposed to collect, store and disseminate 2D/3D geometric and geospatial documentation of inventoried buildings, providing more graphic information than traditional architectural inventories. As a novelty, for the dissemination of information, the creation of a web platform composed of a cartographic viewer (WebGIS) and a point cloud manager based on WebGL technology is proposed as a valuable tool to relate buildings with their environment, characteristic of great importance in the case of heritage located in rural areas

Análisis del diseño de escuelas infantiles desde una visión pedagógica.

The architect's challenge is to design nursery schools that are integrated with the pedagogical project, facilitating the educational work of adults and the learning and discovery of children through the creation of spaces that favor interpersonal relationships, autonomy, creativity or exploration during their first years of life in a physical and social environment. The research addresses the design of nursery schools from the integrating perspective of pedagogy in the architecture project, providing the hidden and silent curriculum that the projected environments confer to the child's formation. Five municipal nursery schools in Zaragoza (Spain) are taken as a case study, undertaken from the experience of many years in the drafting of public teaching facilities, as a means of collecting references for decision-making during the design process. The result is dynamic equipment that adapts to different needs and situations, providing stimuli and experiences that promote learning.El reto del arquitecto es diseñar escuelas infantiles que se integren con el proyecto pedagógico, facilitando la labor educadora de los adultos y el aprendizaje y descubrimiento de los niños a través de la creación de espacios que favorezcan las relaciones interpersonales, la autonomía, creatividad o la exploración durante sus primeros años de vida en un entorno físico y social. La investigación aborda el diseño de escuelas infantiles desde la perspectiva integradora de la pedagogía en el proyecto de arquitectura, aportando el currículum oculto y silencioso que confieren los ambientes proyectados a la formación del niño. Se toman como caso de estudio cinco escuelas infantiles municipales en Zaragoza (España), acometidas desde la experiencia de muchos años en la redacción de equipamientos docentes públicos, como medio para recopilar referencias para la toma de decisiones durante el proceso de diseño. El resultado son equipamientos dinámicos, que se adaptan a diferentes necesidades y situaciones, proporcionando estímulos y experiencias que promuevan el aprendizaje

Long-term ventricular assist devices: characteristics, indications and care from a nursing perspective

RESUMEN: Introducción: La insuficiencia cardiaca (IC) es una afección crónica que afecta entorno a un 4,76,8% de la población. Cada vez existen más personas que padecen esta enfermedad y el número de donantes para trasplante cardiaco ha disminuido. Se ha realizado una búsqueda bibliográfica en distintas bases de datos como Dialnet, Scielo, Medline Plus y Pubmed. La monografía que a continuación se expone consta de cuatro capítulos. En el primer capítulo se exponen los distintos sistemas de asistencia mecánica circulatoria existentes en la actualidad, las características e indicaciones propias de cada uno de ellos. El segundo capítulo se centra en el dispositivo HeartMate III®, el dispositivo de asistencia ventricular (DAV) más usado España actualmente. En el tercero, se aborda el papel fundamental de la enfermería en el proceso de implantación de un DAV. La enfermera coordinadora acompaña al paciente durante todo el proceso siendo una pieza vital. Por último, en el cuarto capítulo se expone una entrevista realizada a un paciente portador de un DAV HeartMate III®. Reflexiones: El desarrollo de estos dispositivos ha supuesto un gran avance en el tratamiento de la IC. Es vital una escrupulosa selección de los pacientes y unos cuidados de enfermería apropiados para garantizar el éxito de la terapia.ABSTRACT: Introduction: Heart Failure is a cronic disease that affects around 4,7-6,8% of population.

Structural safety analysis of the aqueducts 'Coll de foix' and 'Capdevila' of the Canal of Aragon and Catalonia

The Canal of Aragon and Catalonia (CAC) is 134 km long and irrigates 105,000 ha (131 irrigation user communities) and it is owned by the River Ebro’s Water Agency. The aqueducts are located between km 67 and 71 of the canal and were designed by the civil engineer Félix de los Ríos Martín in 1907. The cross-section of both aqueducts, Coll de Foix and Capdevila, was extended within the framework of the project by Fernando Hué Herrero in 1962 in order to reach design flows of 26.1 m3/s and 25.7 m3/s, respectively. The structural performance of the aqueducts has been satisfactory; nevertheless, the hydraulic capacity has reduced over the years. As a result, the irrigation user communities have expressed the need to extend the cross-section of the aqueducts to meet the irrigation demands. Given the age of the structure and the different design considerations at the time, it is paramount to verify the structural reliability of the aqueducts in the new load configuration. Therefore, the objective of this contribution is to present the structural safety analysis conducted and to describe the new extended cross-section for both aqueducts (maintaining the original structural typology).Peer ReviewedPostprint (published version
