An adaptive rectangular mesh administration and refinement technique with application in cancer invasion models
2022
We present an administration technique for the bookkeeping of adaptive mesh refinement on (hyper-)rectangular meshes. Our technique is a unified approach for h-refinement on 1-, 2- and 3D domains, which is easy to use and avoids traversing the connectivity graph of the ancestry of mesh cells. Due to the employed rectangular mesh structure, the identification of the siblings and the neighbouring cells is greatly simplified. The administration technique is particularly designed for smooth meshes, where the smoothness is dynamically used in the matrix operations. It has a small memory footprint that makes it affordable for a wide range of mesh resolutions over a large class of problems. We pre…

New constraints on granulite facies metamorphism and melt production in the Lewisian Complex, northwest Scotland
2018
The research carried out for this study was part of YF's Master Thesis at the Institute of Geoscience, Johannes Gutenberg University, Mainz, which provided the funding for fieldwork and laboratory analyses. TJ acknowledges support from Open Fund GPMR210704 from the State Key Lab for Geological Processes and Mineral Resources, China University of Geosciences, Wuhan. In this study we investigate the metamorphic history of the Assynt and Gruinard blocks of the Archaean Lewisian Complex, northwest Scotland, which are considered by some to represent discrete crustal terranes. For samples of mafic and intermediate rocks, phase diagrams were constructed in the Na2O-CaO‐K2O‐FeO‐MgO‐Al2O3-SiO2-H2O-T…
Efectos del entrenamiento de la fuerza con resistencia variable elástica a lo largo de la vida: una revisión sistemática
2020
The benefits of strength training programs with isoto-nic free weights or machines have been well-documen-ted in all age groups. However, exercise and healthcare professionals sometime question whether it is possible to obtain the same results with devices of variable re-sistance, such as elastic bands. To answer this question, the purpose of this systematic review was to identify and summarize the positive effects of elastic resistance exercises used across the lifespan on health outcomes including body composition, functional and performan-ce capacity, and biochemical variables. A secondary aim was to identify common dosage parameters of strength training programs using elastic resistance…
Krūts audzēju infiltrējošo B šūnu producēto antivielu profilēšana
2015
Pētījumi liecina, ka B šūnas var gan veicināt, gan kavēt vēža veidošanos. Audzējā infiltrēto B šūnu (TIB) daudzums korelē ar slimības gaitu un prognozi, bet mehānismi, kā TIB ietekmē pret-vēža imūno atbildi, joprojām ir neskaidri. Šī darba mērķis ir noskaidrot kādas IgG un IgA klases antivielas B šūnas producē vēža mikrovidē, un vai visas šīs antivielas ir sastopamas arī pacientu plazmā. Ar rekombinanto antigēnu mikročipu palīdzību tika analizēts antivielu repertuārs no krūts vēža un audzējam blakus esošiem krūts audiem iegūto B šūnu kultūru supernatantos un plazmā. Tika atrasti 34 un 31 antigēns pret kuriem veidojas IgG un IgA klases antivielas vēža pacientēm; antigēnu repertuārs bija līdz…
Different approaches to research and innovation in physics education at college and university
2019
Abstract In this article we report a Symposium organized by GTG-Physics Education Research at University (PERU) with different proposals that includes innovative educational approaches and research on problems of teaching-learning physics at university. In the second section, two research projects are described on teaching specific curriculum topics that present special difficulties for students. In the next section the third project on a work experience in the laboratory that takes into account the characteristics of scientific work, is presented. Finally, the fourth project presents a way to investigate the types of student reasoning. In the discussion, the importance of research projects…
Influencia del efecto de la humedad del suelo en la emisividad del infrarrojo térmico
2007
La influencia del efecto de la humedad del suelo en la emisividad del infrarrojo térmico es un hecho conocido pero poco estudiado en el pasado. Se ha diseñado un experimento para calcular la dependencia de la emisividad respecto a la humedad del suelo. Han sido seleccionadas seis muestras de horizontes superficiales de diferentes tipos de suelos mediterráneos. Su emisividad se ha medido con diferentes contenidos de agua de suelo, utilizando la variante de dos tapas del método de caja, mientras que el método gravimétrico ha sido seleccionado para obtener la humedad del suelo. Como resultado de esto, el estudio muestra que la emisividad aumenta significativamente cuando el contenido de agua s…
Distinctive and comparative places: Alternative narratives of distinction within international student mobility
2017
Moving beyond the ‘world-class’ institutional model of international student mobility, this paper examines alternative narratives of distinction relating to place of study. Drawing on semi-structured interviews with international students at universities in the UK, Austria and Latvia, we illustrate how students inside and outside mainstream reputable higher education institutions narrate and reconfigure markers of distinction to validate their international mobility and location of study, in part to compete with peers at other (more prestigious) institutions. We demonstrate the importance of lifestyle and experiential places within a global differentiated higher education landscape and argu…
