The 4th of July 2012 was a milestone date in the history of physics of the last decades. The discovery of the Higgs boson at the ATLAS and CMS experiments thanks to the proton collisions delivered by the LHC not only has ...
Vargas Drechsler, Arturo (Fecha de defensa: 2000-05-12)
La existencia de una relación entre el riesgo a desarrollar un cáncer de pulmón y la exposición al radón y descendientes presentes en el aire se puso de manifiesto hace ya bastante tiempo en la población minera. Desde ...
Pericas, Raimon (Fecha de defensa: 2015-05-15)
The calculations that allow the operating license of the nuclear reactors are usually made using conservative methods. This conservatism, often excessive, limits the actual capabilities of the industry to increase energy ...
Puxeu Vaqué, Josep (Fecha de defensa: 2015-12-22)
The use of small Fields has substantially increased in radiotherapy during recent years mainly due to expansion in the use of modulated techniques which are also used at some institutions for Stereotactic Body Radiotherapy ...
Rigla Pérez, Juan Pablo (Fecha de defensa: 2013-10-09)
During last four or five decades there has been a growing demand in particle accelerators which can provide electron beams in the energy ranging from 2 MeV to 100 MeV with high energy resolution and good dose control. Other ...

Beta delayed neutron emission probability is one of the main properties of neutron rich nuclei away from the valley of beta stability. The knowledge of this parameter provides the opportunity to extend the information on: ...
López Vilanova, Natàlia (Fecha de defensa: 2019-04-03)
The aim of this thesis was to assess and develop internal dose calculations methods in diagnostic and therapeutic nuclear medicine procedures to patients undergone PET/CT explorations. Towards this objective, the accuracy ...
Rodriguez-Chiang, Lourdes (Fecha de defensa: 2018-05-04)
Sustainability of resources such as energy, water and waste have become important drivers in our current economy. For large industries that are water and energy intensive like pulp and paper (P&P) mills, this is a specifically ...
Espinal Bustos, Raúl Uziel (Fecha de defensa: 2013-12-20)
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 ...
Beltrán Vilagrasa, Mercè (Fecha de defensa: 2012-12-14)
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 ...
Camp Brunés, Anna (Fecha de defensa: 2017-09-15)
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. ...
Wegener, Moritz (Fecha de defensa: 2021-02-12)
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 ...
Coello de Portugal - Martínez Vázquez, Jaime Maria (Fecha de defensa: 2021-06-16)
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 ...
Casanovas Hoste, Adrià (Fecha de defensa: 2020-10-27)
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 ...
Salvador Castiñeira, Paula (Fecha de defensa: 2014-11-07)
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 ...
Hedayati, Ali (Fecha de defensa: 2016-09-26)
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 ...
