Application of total internal reflexion fluorescence microscopy for studying pH changes in an occluded electrochemical cell: Development of a wavegui…
2006
A device for pH mapping derived from optical sensors similar to total internal reflection fluorescence microscopy (TIRFM) has been developed for future possible applications in the field of localized corrosion. The sensing principle is the increase of the fluorescent yield of the fluorescein with the pH of the medium. The basic principle of this sensor is based on the excitation of a fluorescent silica polymer film of nanometre dimensions, deposited by sol–gel method on a waveguiding layer. The total internal reflexion conditions creates an evanescent wave which interacts with the molecules trapped in the silica layer. A conventional microscope located above the sample collects the fluoresc…

Challenging gender relations in PE through cooperative learning and critical reflection
2018
Research continues to highlight how gender is reproduced through pedagogical practice in Physical Education (PE), but there has been much less focus on how it might be challenged. This paper report...
Una gramática escolar interlingüística. Hacia una enseñanza reflexiva de las lenguas en contextos multilingües
2022
El reto de la educación plurilingüe requiere una enseñanza de las lenguas curriculares que promueva la reflexión sobre el uso y la transferencia lingüística para desarrollar la competencia comunicativa del alumnado. En este sentido, el proyecto Egramint se plantea la elaboración de una gramática escolar interlingüística como instrumento de formación docente y de intervención en el aula. Metodológica-mente, es una investigación de carácter cualitativo-etnográfico en tres fases. En la primera, sobre la que versa este artículo, abordamos el análisis documental de los currículos oficiales del ámbito español para delimitar cómo se configura en ellos la gramática escolar. Los resultados muestran …
Learning via Summarizing Infographics Assignment in Software Engineering Management e-Course?
2020
This Research-to-Practice, Work in Progress Paper focuses on how learners experience creation of infographics as a summarizing assignment in an advanced level e-course on software engineering management (SEM). We have previously investigated how learners perceive infographics as a repeated reflection assignment during a requirements engineering e-course. To complement this research project, we studied how learners experience the use of infographics as a method for summarizing a whole software engineering management course in e-education setting. The SEM course participants (N=36) found that infographics as a summarizing assignment required complex learning that was altogether deemed highly …
A reflection approach to the broken ray transform
2013
We reduce the broken ray transform on some Riemannian manifolds (with corners) to the geodesic ray transform on another manifold, which is obtained from the original one by reflection. We give examples of this idea and present injectivity results for the broken ray transform using corresponding earlier results for the geodesic ray transform. Examples of manifolds where the broken ray transform is injective include Euclidean cones and parts of the spheres $S^n$. In addition, we introduce the periodic broken ray transform and use the reflection argument to produce examples of manifolds where it is injective. We also give counterexamples to both periodic and nonperiodic cases. The broken ray t…
The moral work of becoming a professional
2021
Abstract In contemporary working life, art-based initiatives are increasingly used in organizational training and development. For artists, this has created new employment opportunities as creative entrepreneurs who provide specialist services for workplaces. In this article, we study the dynamics of such encounters through the narrated accounts of training professionals. Our data come from a professional mentoring program where the working pairs of artists and consultants shared stories about their customer projects. By using conversation analysis as a method, we analyze the way stories are interactionally accomplished in peer group sessions of the program. In particular, we analyze how pa…
Industrial Environment Mapping Using Distributed Static 3D Sensor Nodes
2018
This paper presents a system architecture for mapping and real-time monitoring of a relatively large industrial robotic environment of size 10 m × 15 m × 5 m. Six sensor nodes with embedded computing power and local processing of the 3D point clouds are placed close to the ceiling. The system architecture and data processing is based on the Robot Operating System (ROS) and the Point Cloud Library (PCL). The 3D sensors used are the Microsoft Kinect for Xbox One and point cloud data is collected at 20 Hz. A new manual calibration procedure is developed using reflective planes. The specified range of the used sensor is 0.8 m to 4.2 m, while depth data up to 9 m is used in this paper. Despite t…
El doble rechazo de la reflexión en Ser y tiempo
2021
The objective of this article is to clarify the Heideggerian rejection of the idea of reflection as the method of philosophy. The need for such explanation lies on the counterintuitive nature of this philosophical thesis and on the interpretive problems that this criticism presents in Being and Time. In order to solve them, a brief historical-conceptual examination of the reflection is realized, leading to two different meanings of the concept, a psychological and a transcendental one. Thanks to this distinction, it is possible to expose systematically the double criticism presented in Being and time and, therefore, clarify the ultimate reasons underling the Heideggerian rejection of the …
Recurrence Quantification Analysis as a Methodological Innovation for School Improvement Research
2021
Contains fulltext : 240653.pdf (Publisher’s version ) (Closed access) School improvement and educational change can be facilitated by learning through reflection, as this allows teachers to discover ways to develop and adapt to change. Higher levels of engagement in reflection have been found to be beneficial, but it is unclear from which everyday routine in engagement in reflection higher levels arise, and thus whether occasions to make knowledge explicit should be organized with a certain constancy. In this study, we therefore used a conceptualization of teacher learning through reflection as a situated and dynamic process in which available environmental information, learning activities,…
