In our work we studied some aspects of biochemical quality in the rehabilitation process of degraded soils through the application of sewage sludge. As biochemical quality parameters we focused on the carbon cycle, through ...
The illegal on-street parking is one of the traffic elements that has more effect in urban environments provoking the presence of bottlenecks in the different roads and, consequently, facilitating the appearance of congestion. ...
This PhD Thesis is the fruit of the job of the author as a researcher at Scytl Secure Electronic Voting, as well as the collaboration with Paz Morillo, from the Department of Applied Mathematics at UPC and Alex Escala, PhD ...
La malària és encara avui en dia una malaltia que causa aproximadament un milió de morts a l'any a tot el món. La seva eradicació suposa un gran repte per a la humanitat i per a la comunitat científica, en particular. El ...
La microbiologia predictiva és una de les parts més importants de la microbiologia dels aliments. En el creixement d'un cultiu bacterià es poden observar quatre fases: latència, exponencial, estacionària i mort. La fase ...
Saccharomyces cerevisiae is one of the yeasts with major economic, social, and health significance in human culture. Depending on the growth conditions experienced by the cell, S. cerevisiae growth can proceed via fermentative, ...
Micro-seismicity, and especially felt seismicity, induced by Enhanced Geothermal Systems (EGS) operations is a matter of scientific interest, not only because of the related risks and concerns, but also because the ...
Induction heating is a heating method for electrically conductive materials that takes advantage of the heat generated by the Eddy currents originated by means of a varying magnetic field. Since Michael Faraday discovered ...
In recent years, contactless energy transfer systems have been developed and investigated widely. As evident, the transfer energy is performed without physical connection. This technology is classified according to power ...
En esta tesis se estudia, mediante simulación numérica directa de las ecuaciones de Navier-Stokes, la dinámica de un fluido en el interior de un anillo cilíndrico en rotación con las tapas ligeramente inclinadas y sometido ...
La necesidad del análisis de supervivencia aparece cuando necesitamos estudiar las propiedades estadísticas de una variable que describe el tiempo hasta que ocurre un evento único. En algunas ocasiones, podemos observar ...
Antibiotic (AB) Resistance is an increasing global problem for public health, with multi-resistant bacteria persisting and spreading not only in clinical settings but also in the environment. One of the possible vectors ...
A large number of underground works are under construction in several big cities around the world (London, Paris, Amsterdam, Beijing, Shanghai, Chicago, Caracas, Mexico D.F., and Riad, for instance): railway tunnels, water ...
(English) Axial forces in columns of moment-resisting frames (MRF) have a paramount role for the seismic performance of these structural systems. Nonetheless, there are significant gaps in the literature entailing the ...
The dynamic response of any structure submerged in water is significantly modified by the effect of added mass. The inertia of the fluid that the body must accelerate during its vibrational motion decreases its natural ...
Coastal areas concentrate very high socio-economic and natural values, which will be highly threatened by climate change, particularly by sea-level rise (SLR). Given the intrinsic characteristics of this zone, appropriate ...
(English) Lightning strikes to aircraft and wind turbines can lead to substantial repair expenses. These structures often trigger lightning strikes, in the form of bidirectional leaders in the case of aircraft and upward ...
Timber frame structures which constitute an important cultural heritage of many countries, are well known as efficient seismic resistant structures worldwide and are worth to be preserved. Himis is one common traditional ...
El propósito de la presente tesis es estudiar la influencia de la logística inversa en las capacidades de fabricación, refabricación y almacenaje óptimas de un sistema industrial. El interés por la logística inversa ha ...
La utilización de circona tetragonal policristalina estabilizada con 3 % mol de itria (3Y-TZP) para fabricar coronas e implantes ha sufrido una fuerte expansión recientemente debido a las buenas propiedades mecánicas, ...
