    Rheological behaviour of fruit and milk-based smoothies

    Two of the most important food attributes for today´s fast-moving lifestyle are convenience and healthiness [1-2]. Fast-moving lifestyle specifically affects to elderly people, who are prone to bad-nutrition due to their dental status reducing the consumption of fruits and vegetables [3]. Smoothies are blended beverages, and good examples of convenient and healthy foods for helping to reduce this problem. So, they are gaining increasing market leverage in the beverage sector. Texture and rheological behaviour of foods can determine their acceptability. Therefore, added to nutritious features, smoothies must also account with outstanding mechanical properties. Stability of the products is also a main quality, which can be gained adding a small amount of stabiliser to beverage formulations. But, to avoid opposite effects, stabilisers addition should ameliorate the product texture.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech

    • Changes in flow properties upon the application of an electrical field can be evaluated using of electrorheological techniques. • The fact that it had shown successful to reduce the fat content [1] has aimed us to explore potential benefits resulting from the wide use of this technique in food science. • It was claimed long time ago that the integration of this technique in food processing should translate into the development of new products [2]. • A study on the influence of the solid content and temperature on the steady viscous flow electrorheological behavior of wheat flour/olive oil dough has been made. • The overall conclusion is that this system is electrorheological positive, i.e. the yield stress increases with the electric field.Universidad de Málaga.

    Reaction-Diffusion Equations with Non-Autonomous Force In H-1 and Delays Under Measurability Conditions on The Driving Delay Term

    In this paper we analyze the existence of solutions for a reaction–diffusion problem with hereditary effects and a time-dependent force term with values in H−1. The main novelty is that the delay term may be driven by a function under very minimal assumptions, namely, just measurability. This is due to the fact that we only deal with a phase-space of functions continuous in time, allowing this general setting, which might be more useful when less regularity is known in the hereditary mechanism. After that, we obtain uniform estimates and asymptotic compactness properties (via an energy method) that allow us to ensure the existence of pullback attractors for the associated process to the problem. Actually, we obtain two different families of minimal pullback attractors, namely, those of fixed bounded sets but also for a class of time-dependent families (universe) given by a tempered condition. Finally, from comparison results, we establish relations among them, and under suitable additional assumptions we conclude that these families of attractors are in fact the same object

    Attractors for a Double Time-Delayed 2D-Navier-Stokes Model

    Get PDF
    In this paper, a double time-delayed 2D-Navier-Stokes model is considered. It includes delays in the convective and the forcing terms. Existence and uniqueness results and suitable dynamical systems are established. We also analyze the existence of pullback attractors for the model in several phase-spaces and the relationship among them

    Intervención desde la Farmacia Comunitaria de la Hiperplasia Benigna de Próstata

    Get PDF
    En el presente Trabajo fin de Grado se ha realizado una revisión bibliográfica que recoge todo el proceso diagnóstico de la Hiperplasia Benigna de Próstata y su posterior seguimiento. La HBP es la enfermedad urológica más frecuente en el varón mayor de 50 años y su incidencia sigue aumentando proporcionalmente al aumento en la esperanza de vida de la población. La HBP es el agrandamiento no canceroso de la glándula prostática. Su sintomatología se manifiesta cuando el crecimiento de la glándula comienza a obstruir los conductos de salida de la orina, dando lugar a los Síntomas del Tracto Urinario Inferior (STUI). Este tipo de sintomatología puede llegar a ser muy limitante en el día a día de quienes la padecen. El diagnóstico y tratamiento precoz de esta patología puede evitar complicaciones y controlar su progresión. Ante la sospecha de HBP en un paciente, el farmacéutico puede emplear el cuestionario I-PSS (International Prostate Symtom Score) para valorar la gravedad de la sintomatología. Como farmacéutico podrá dar recomendaciones en cuanto al estilo de vida o derivar al médico de Atención Primaria si se considera necesario. Tras la confirmación del diagnóstico, el médico prescribirá un tratamiento que irá encaminado a mejorar la calidad de vida de los pacientes y a controlar la progresión de la enfermedad. El seguimiento farmacoterapéutico por parte del farmacéutico comunitario optimizará el tratamiento controlando su cumplimiento y efectividad mediante revisiones periódicas. Finalmente, destacar el papel que puede jugar la atención farmacéutica en una farmacia comunitaria en la detección precoz de patologías y en el seguimiento y control de la adherencia al tratamiento.Universidad de Sevilla.

    Pullback Attractors for Three-Dimensional Non-Autonomous Navier-Stokes-Voigt Equations

    Get PDF
    In this paper, we consider a non-autonomous Navier–Stokes–Voigt model, with which a continuous process can be associated. We study the existence and relationship between minimal pullback attractors for this process in two different frameworks, namely, for the universe of fixed bounded sets, and also for another universe given by a tempered condition.Since the model does not have a regularizing effect, obtaining asymptotic compactness for the process is a more involved task. We prove this in a relatively simple way just using an energy method. Our results simplify—and in some aspects generalize—some of those obtained previously for the autonomous and non-autonomous cases, since for example in section 4, regularity is not required for the boundary of the domain and the force may take values in V′. Under additional suitable assumptions, regularity results for these families of attractors are also obtained, via bootstrapping arguments. Finally, we also conclude some results concerning the attraction in the D(A) norm
