This thesis proposes a new methodology to determine quality parameters of meat products (Iberian loin and ham) in a non-destructive way.Firstly, Magnetic Resonance Imaging (MRI) are obtained from meat products, evaluating three acquisition sequence (Spin Echo -SE-, Gradient Echo -GE-and Turbo 3D -T3D-). Later, MRI is analysed by applying different texture algorithms (GLCM, GLRLM and NGLDM) and fractals algorithms (CFA, FTA and OPFTA); the last two ones have been developed in this thesis. These algorithms extract texture features from the MRI. At the same time, the meat products are also analysed by means of physico-chemical and sensory techniques. Finally, different data mining techniques are applied on all obtained data: deductive (Multiple linear regression -MLR-), classification (Decision trees -DT-and Rules-based systems -RBS-) and prediction techniques (MLR and Isotonic regression -IR-).The accuracy of the analysis of quality parameters is affected by the MRI acquisition sequence, the algorithm used to analyse them and the data mining technique applied. In general, the use of SE as MRI acquisition sequence, and GLCM or OPFTA as image analysis algorithm could be indicated. Considering the data mining techniques, MLR and DT are appropriate, respectively, to deduce physico-chemical parameters and to classify as a function of salt content. Regarding to the predictive technique, MLR could be indicated. It offers reliable equations to determine the quality parameters, and, allows analysing the quality of meat products in a nondestructive, efficient, effective and accurate way.

“…En la villa había comunidad judía y, aunque junto al monasterio no hubo frailes 86 , su itinerancia facilitaba presencias; su advocación, con la que se rememoraba a un gran predicador e inquisidor, era reclamo simbólico. La reina desarrolló su política conventual en poblaciones con presencia judía y sin duda quiso atajar el problema; indicio de ello sería el programa iconográfico antijudío de la iglesia de Nieva 87 . Sin embargo, este objetivo de predicación antijudía, notoriamente político, no ha sido destacado por la cronística dominica entre sus intenciones fundacionales y sí muy subrayado en Fernando de Antequera.…”

Resumen: La fundación de conventos y monasterios y las políticas desarrolladas en torno a estos espacios de espiritualidad constituyen una interesante herramienta de conocimiento del oficio regio femenino en su concepción y praxis. Analizamos en esta clave las actuaciones de Catalina de Lancaster, con interesantes diferencias entre sus etapas como reina consorte y regente. Ello permite mostrar su concepto como "mujer política" arraigada en la noción de un principio político femenino, así como los frentes de acción que desarrolló en este ámbito y que no fueron únicamente simbólicos o propagandísticos.Palabras clave: Catalina de Lancaster; Reginalidad; Orden de Predicadores; Fundaciones religiosas. Abstract:A knowledge of the foundation of convents and monasteries and the policies surrounding these spaces of spirituality proves an interesting stepping-stone towards a better knowledge of both the concept and practice of queenship. The work of Catherine of Lancaster is analyzed in this light, and the differences between her periods as queen consort and queen regent are revealed. An insight is provided into the queen as a 'female politician', rooted in the notion of a 'female policy', and into her action fronts in this area, which were more than merely symbolic or propagandistic.

“…At the industrial level, the post-salting is empirically controlled by mass difference. Therefore, to quantify the salt content and diffusion in the ham it is necessary to carry out destructive determinations or the application of advanced and complex technologies, such as: computed tomography (3), magnetic resonance imaging (4,5), magnetic resonance microscopy (6). However, impedance spectroscopy is a low cost technique that has shown good results in the evaluation of meat products (7).…”

Background: The smart control for food and feed technologies consist in the development of new methods that facilitate the control of productive processes guaranteeing the quality and safety of agrofood products. The importance given to this research line is a clear indicator of the interest of all of the agents implicated in promoting the introduction of innovative technologies. The goal is to implement new, fast, economical, analytical techniques, which constitute a real alternative to traditional control procedures. Objective: The aim of this study was to evaluate the use of an electronic sensor based on the impedance spectroscopy technique for the characterization of hams during the post-salting step (8, 10, 12 and 14 weeks). Materials and methods: 60 hams from three different categories (fat, semi-fat and lean), were tray salted under the conditions of a company (x NaCl = 0.11 g/g dry matter). For each time, samples were first evaluated with the electronic method (non-destructive analysis) and then analytical determinations of: mass variation, moisture content, fat content, salt content and water activity were performed on each ham in different zones. The electric data were evaluated using Principal Component Analysis (PCA) and regression with Partial Least Squares (PLS) through the analytical data. Results: The PCA analysis discriminated between the different evaluated zones. At eighth week 79.06% of the variance was explained and at tenth week, the 82.53%. No relation was observed for the different ham categories. The correlation between the impedance signal and the analytical determinations showed the best cross validation coefficient (R 2 CV) values for moisture content (0.75) and water activity (0.73). Conclusions: The impedance spectroscopy technique generated different signals between the zones of analysis during the first two post-salting times, eight and ten weeks, in which physicochemical differences were also observed as a consequence of the variation in the salt concentration between zones.
