[eng] The continuous increase in adulterations and contamination in food puts the integrity of food under continuous threat, which generates suspicion in the consumer. For these reasons, assuring the quality, authenticity, ...
Bacterial infections are a major health concern worldwide due to the mortality and comorbidity associated levels. Besides the development of drug-resistance mechanisms, most recalcitrant infections are caused by bacteria ...
The purpose of this thesis is to put forth and present a series of new applications of the gauge/string duality to areas of high energy physics and condensed matter physics. The contributions showcased in this thesis amount ...
El Niño Southern Oscillation arises in the tropical Pacific due to coupled atmosphere-ocean interactions. The nature of the dynamical system of the atmosphere is chaotic and its predictability is sensitive to initial ...
Linum album is an herbaceous plant with medical interest due to its content of podophyllotoxin (PTOX), an aryltetralin lignan with cytotoxic activity. The study of biotechnological alternatives has generated big interest. ...
The main contribution of this doctoral thesis has been devoted to the field of synthetic organic chemistry. The Pauson-Khand reaction (PKR) is a metal-catalyzed [2+2+1] cycloaddition between an alkyne, an alkene and a ...
Los estallidos de rayos gamma (del inglés gamma-ray bursts o GRBs para abreviar) se han clasificado tradicionalmente en GRBs cortos y duros, y GRBs largos y blandos, de acuerdo a la distribución biomodal de sus duraciones. ...
[eng] The study of the 3D structural details of protein-protein and protein-DNA interactions is essential to understand biomolecular functions at the molecular level. Given the difficulty of the structural determination ...
The current trend in exoplanet research focuses on the detection and characterisation of Earth-sized planets, and the study of their potential subtle and tenuous atmospheres. The aim of this thesis is the development of ...
[eng] Gelatinous zooplankton has been studied in the Western Mediterranean for a long time, however, its spatial structure has been mainly addressed in coastal areas, during spring and summer periods. Hence, information ...
Nowadays, researchers have spent considerable effort on the development of new materials, with new properties and characteristics, and new methods of synthesis, in order to meet the demands of a market that is constantly ...
Hepatocellular Carcinoma (HCC) is one of the most common cancers. During hepatocarcinogenesis (a multistep process) there is a disruption of the balance between cell death and survival signalling pathways, where pro-apoptotic ...
The air and environment quality is, nowadays, one of the main political concerns of the governmental institutions. Suitable gas detection is nowadays an important requirement, which is provided by gas sensors. Metal oxide ...
STUDY I HYPOTHESIS Genetic alterations have already been recognized as major etiological factors for ASD and ID, of which RTT is an example. In addition to the contribution of polymorphic variants that confer low or ...
The central topic of this thesis has been the study, development and validation of diverse multiplexed diagnostics platforms and techniques that can be applied to a wide range of topics, from environmental monitoring to ...
The pleiotropic WT1 transcription factor (WT1) was first discovered in renal tumours. It contains four zinc-finger motifs at the C-terminus which are important for DNA binding to activate gene expression and is also involved ...
Lycopene is an antioxidant carotenoid present in high amounts inside the ripe tomato fruit, in watermelon, red bell pepper and a few other red-pigmented fruits. Its health benefits, notably the prevention of prostate cancer ...
Maldacena's conjecture, often known as the holographic duality or the AdS/CFT correspondence, proposes an equivalence between gravitational theories in a hyperbolic space of a certain dimensionality and gauge theories ...
[eng] Speaking metaphorically, the human nervous system is a complex ensemble of millions of parts operating together one with another. For this reason, each part is fundamental for the correct function of the whole system. ...
The aim of the present thesis is directed towards the comprehension of the mechanisms involved in the regulation of lipid and carbohydrate metabolism in relevant species in European aquaculture. Special attention has been ...
