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 ...
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 ...
Hernández Masgrau, Víctor (Fecha de defensa: 2013-11-07)
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 ...
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 ...
Gorlychev, Vitaly (Fecha de defensa: 2014-02-05)
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: ...
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 ...
García Morales, Héctor (Fecha de defensa: 2015-01-16)
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 ...
Jiménez Divins, Núria (Fecha de defensa: 2015-04-10)
This Thesis focuses on the study of the catalytic production of hydrogen from a biofuel, namely the bioethanol. It also studies the subsequent purification of pre-cleaned reformate streams. The end use of the hydrogen ...
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 ...
Domínguez Escalante, Montse (Fecha de defensa: 2016-01-15)
Hydrogen is an energy vector; it is not a direct energy source. It is an energy carrier. Hydrogen can be used to feed fuel cells (an electrochemical device), thus increasing the efficency of energy transfer as the amount ...
Gallego Blanco, Judith (Fecha de defensa: 2016-02-02)
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 ...
Rodríguez Castillo, Miguel Lázaro (Fecha de defensa: 2016-02-05)
The main result of this thesis is a software system, called PRIMO, which simulates clinical linear accelerators and the subsequent dose distributions using the Monte Carlo method. PRIMO has the following features: (i) it ...
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 ...
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. ...
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 ...
Castedo Rodríguez, Alejandra (Fecha de defensa: 2018-09-21)
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 ...
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 ...
