Hydrogen constitutes a promising alternative to manage our energy supply more efficiently. Hydrogen can be stored and used in fuel cells to produce electricity, where it combines with the oxygen present in the air and ...
En aquesta tesi s’estudien les implicacions dosimètriques que comporten els canvis anatòmics que pateixen els pacients afectats de càncer de cap i coll (CCC) durant el tractament de radioteràpia (RT). L’estudi es realitza ...
The present thesis is focused on the improvement of radiological surveillance networks using gamma spectrometry. Tipically they are equipped with gamma dose rate monitors, while they do not have gamma spectrometry monitors. ...
The colossal risks and challenges posed by climate change require innovative solutions that must fulfil energy service demands sustainably. The concept of small-scale, biomass-based polygeneration (SBP) is one such ...
The Barcelona metropolitan area (BMA; 3.2 M inhabitants) has an integrated urban water cycle management. Different type of treatment plants are located along the drinking, sewerage and reuse networks where specific treatments ...
In order to increase the performance of particle colliders, it is crucial to make the beam sizes at the collision points as small as possible. This causes an increase of the beam size in the region surrounding the collision ...
Neutron capture cross sections are fundamental in the study of the slow neutron capture process of nucleosynthesis, also known as the s-process, which produces half of the observed solar system abundances of elements heavier ...
A recent sensitivity analysis done for the new generation of fast reactors [1] has shown the importance of improved cross section data for several actinides. Among them, the neutron-induced fission cross section of 240,242Pu ...
Hydrogen is considered as a clean energy carrier that can be converted to electricity by fuel cell with high efficiency. To be economically feasible and comparable, hydrogen needs to be liquefied, compressed, or adsorbed ...
La determinació de l’índex alfa total en aigües és d’interès per ser un dels paràmetres inclòs en la legislació nacional e internacional associada a la qualitat de l’aigua per al consum humà. Aquest índex informa de la ...
Radiation therapy is one of the main modalities used for treating cancer patients, together with surgery and chemotherapy. Radiotherapy treatments can be carried out with a great variety of devices, but most treatments are ...
The depletion of fossil fuels and increase of global warming lead to a high demand for alternative energy sources that should be cheap and renewable to fulfill the future energy demand. The photocatalytic generation of H2 ...
Dopaminergic neurotransmission SPECT studies with 123I-labelled radioligands can help in the diagnosis of neurological and psychiatric disorders such as Parkinson¿s disease and schizophrenia. Nowadays, interpretation of ...
With the issue of the rise of anthropogenic CO2, global warming and rise of the primary energy demand, strong measures for the energy transition and the diversification with renewables and existing fossil-based infrastructure ...
Compton cameras are used for radiological imaging, which can be useful in environmental applications and especially in determining the position of hidden sources. Current Compton cameras are based on pixelated detectors ...
Among the platform chemicals that can be produced from lignocellulosic biomass, furfural (FUR) constitutes a promising intermediate that can be processed into a variety of advanced end products. In this thesis, the ...
