La unión europea y la inmigración irregular en el contexto del derecho internacional.
2005
La tesis trata de cómo el Derecho internacional público regula el fenómeno de la inmigración irregular y como ese modelo es asumido por la Unión Europea. En el terreno de la percepcion del fenómeno la inmigración irregular se entiende dentro de la UE producto de los diferentes factores internacionales de empuje y atracción, es un fenómeno evitable y al mismo tiempo responsabilidad de las mafias. En lo que respecta la autopercepción la UE, que se tiene a sí misma como una Organización internacional avanzada y respetuosa con los derechos humanos, considera que tiene la obligación de abordar el fenómeno con responsabilidad y con el debido respeto a los derechos de los inmigrantes y al Derecho …
La acción internacional contra el hambre y la ayuda alimentaria al desarrollo de la Unión Europea.
2005
El trabajo constituye un intento de reflexión crítica sobre algunos de los aspectos más nuevos y controvertidos de la lucha contra el hambre y el papel que la ayuda alimentaria al desarrollo desempeña en la misma, tanto en el ámbito multilateral general como en el comunitario. Su objetivo es poner de relieve la insuficiencia de las medidas adoptadas hasta el momento para hacer frente a este problema, a través del examen de uno de los principales instrumentos internacionales y en general de la acción internacional puesta en marcha en las últimas décadas.Resulta de todo punto inadmisible que en pleno siglo XXI la sociedad internacional no haya sido capaz de instrumentalizar acciones eficaces,…
La asociación interregional entre el mercosur y la unión europea: balance y perspectivas.
2003
RESUMEN El presente trabajo tiene por objeto el análisis de las relaciones entre la Unión Europea y el MERCOSUR con vistas a la creación de una zona de libre comercio interregional, en el marco de un proyecto de asociación interregional entre ambos bloques. El estudio del tema presenta singular interés pues es un punto de especial importancia en el marco de las relaciones de la Unión Europea con América Latina y el éxito del proceso culminará con el surgimiento de la primera zona de libre comercio internacional entre dos uniones aduaneras, una nueva figura de Derecho Internacional, con importantes repercusiones en el comercio mundial. En el Capítulo I, se analiza la evolución del panorama i…
Green Composites Based on PLA and Agricultural or Marine Waste Prepared by FDM
2021
Three dimensional-printability of green composites is recently growing in importance and interest, especially in the view of feasibility to valorize agricultural and marine waste to attain green fillers capable of reducing bioplastic costs, without compromising their processability and performance from an environmental and mechanical standpoint. In this work, two lignocellulosic fillers, obtained from Opuntia ficus indica and Posidonia oceanica, were added to PLA and processed by FDM. Among the 3D printed biocomposites investigated, slight differences could be found in terms of PLA molecular weight and filler aspect ratio. It was shown that it is possible to replace up to 20% of bioplastic …
3D-Printed Products for Topical Skin Applications: From Personalized Dressings to Drug Delivery.
2021
3D printing has been widely used for the personalization of therapies and on-demand production of complex pharmaceutical forms. Recently, 3D printing has been explored as a tool for the development of topical dosage forms and wound dressings. Thus, this review aims to present advances related to the use of 3D printing for the development of pharmaceutical and biomedical products for topical skin applications, covering plain dressing and products for the delivery of active ingredients to the skin. Based on the data acquired, the important growth in the number of publications over the last years confirms its interest. The semisolid extrusion technique has been the most reported one, probably …

Enabling Sociability When Using Virtual Reality Applications : A Design Science Research Approach
2019
Immersive virtual reality applications aim at providing an all-encompassing spatial experience where a user can feel like being in another world or dimension. The systems are inherently designed for individual use as the devices disconnect the user from the physical environment. However, the applications are seldom used alone. Specifically, when used for sales and marketing, the user often needs help from other people but also benefits from social interaction as a part of the experience. Design research methodology is applied to three iterative development versions of a virtual-reality application. The focus of the evaluation of the artifacts is in the social use emphasizing three sociabili…
Problem Space Identification for Developing Virtual Reality Learning Environments
2021
Our study argues that the extant literature on virtual reality-based learning environments (VRLEs) currently lacks proper definitions and context descriptions for a problem space, which is fundamental for conducting design science research (DSR). Without properly conducted problem space identification, the most pivotal problems cannot be identified resulting solutions lacking validity and unreliable evaluations. This is a major challenge for the DSR in the educational field, but also for the research on VRLEs. The purpose of this paper is to introduce a novel DSR method to support rigorous problem space identification, which would allow rigorous and profound problem space analysis. The inst…
Soil moisture variations from boreal forests to the tundra
2023
Soil moisture has a profound influence on life on Earth, and this vital water resource varies across space and time. Here, we explored soil moisture variations in boreal forest and tundra environments, where comprehensive soil moisture datasets are scarce. We installed soil moisture sensors up to 14 cm depth at 503 measurement sites within seven study areas across northern Europe. We recorded 6,138,528 measurements to capture soil moisture variations of the snowless season from April to September 2020. We described the spatio-temporal patterns of soil moisture, and test how these patterns are linked to topography and how these links vary in space and time. We found large spatial variation a…
