    The influence of the slaking method on the characteristics of lime putties has been investigated. There has been used the same raw lime, calcined in a traditional kiln, to perform in situ traditional slaking processes as well as laboratory controlled slaking processes. The obtained lime putties were characterized using different instrumental techniques such as X-ray diffraction (XRD), X-ray fluorescence (XRF), thermogravimetric analysis (TGA), specific surface area (BET), particle size using laser dispersion and viscosity. Particle morphology using scanning electron microscope (SEM) was also studied. The amount of water used during slaking as well as the temperatures distribution give raise to differences in the particle size distribution and in the resulting hydration products.

    Background Rapid pacing rates induce alternations in the cytosolic calcium concentration caused by fluctuations in calcium rele However, the relationship between calcium alternans and refractoriness of the SR calcium release channel (RyR2) Methodology/Principal Findings To investigate how ryanodine receptor (RyR2) refractoriness modulates calcium handling on a beat-to-beat basis u used a mathematical rabbit cardiomyocyte model to study the beat-to-beat calcium response as a function of RyR were constructed depicting the beat-to-beat response. When alternans was observed, a novel numerical clamping was caused by oscillations in SR calcium loading or by RyR2 refractoriness. Using this protocol, we identified regio loading or RyR2 refractoriness underlie the induction of calcium alternans, and we found that at the onset of altern inactivation rates of the RyR2, calcium alternans was caused by alternation in SR calcium loading, while at low act level of available RyR2s. Conclusions/Significance We have mapped cardiomyocyte beat-to-beat responses as a function of RyR2 activation and inactivation, identify refractoriness underlie the induction of calcium alternans. A corollary of this work is that RyR2 refractoriness due t of calcium alternans even when alternation in SR calcium load is present.

    In this work we use a computer model of a ventricu- lar rabbit myocyte to study several factors that affect sar- coplasmic reticulum (SR) calcium load, such as hypercal- cemia, SR calcium buffering, or ryanodine receptor (RyR2) dynamics. General conditions for the appearance of cal- cium spontaneous release in situations with calcium over- load are obtained. Furthermore, we study the appearance of alternans under these conditions. The presence of cal- cium alternans may be due to either a steep calcium load release relation, resulting in oscillations in SR Ca content, or to a slow recovery from refractoriness of the RyR2. We find that a change in calsequestrin buffering dynamics or extracellular calcium concentration greatly affects the ap- pearance of the former type of alternans, but not of the latter.

    La cal, que había sido el material conglomerante por excelencia en el sector de la construcción se ha visto relegada casi exclusivamente, a partir de la irrupción generalizada del cemento, al mundo de la restauración, donde todavía perduran profesionales y artesanos con oficio. Estos profesionales de la restauración valoran especialmente la trabajabilidad de la cal en estado fresco, y consideran que una cal en pasta envejecida tradicionalmente ofrece mejores prestaciones que una cal en pasta coetánea o que una cal en polvo. Esta mejor trabajabilidad se traduce en mayor viscosidad. El motivo de esta tesis es investigar en la caracterización a nivel microscópico de las cales y en el comportamiento deformacional en estado fresco, para así poder confrontar el conocimiento tradicional desde la investigación científica. Al mismo tiempo, una segunda línea de investigación se ha centrado en verificar la aplicabilidad de distintas herramientas de medida para caracterizar las pastas de cal y las cales en pasta. Para la realización de esta tesis se han escogido algunas de las diferentes cales disponibles en el mercado y que pueden servir de ejemplo de las distintas maneras de fabricar y de producir este material y se han estudiado: la caracterización de las partículas que componen las pastas de cal mediante la granulometría láser, la Difracción de Rayos X (DRX) y la microscopia electrónica; y también se ha estudiado el comportamiento deformacional de las cales a partir de la medida de la viscosidad. Otra parte importante de la investigación realizada se ha centrado en discernir cómo evolucionan las pastas de cal en el tiempo y tras procesos de agitación. Los resultados obtenidos de estos trabajos demuestran la aplicabilidad de la técnica de la granulometría láser y la medida de la viscosidad como herramientas válidas para caracterizar las cales, mientras que se demuestra que el parámetro A[0001] obtenido a partir de la DRX no es válido para datar la antigüedad de la cal en pasta. También ha quedado demostrada la capacidad que tienen las cales en polvo de evolucionar incrementando su viscosidad y su carácter tixotrópico tras breves períodos de estacionamiento en forma de pasta de cal. En cuanto a las cualidades de las cales en pasta envejecidas tradicionalmente, se ha constatado que éstas presentan, en general, mayores viscosidades y distribuciones de tamaños de partículas menores que las de las pastas de cal. La evolución del proceso de envejecimiento de una cal en pasta no conduce siempre e indefinidamente a resultados mejores. Por tanto, no siempre una cal en pasta envejecida y de más edad es mejor que una cal más joven.

    Since the widespread irruption of the cement, the lime, which once had been the binding material par excellence in the construction sector, has been relegated almost exclusively to the world of restoration works, where skilled professionals and craftsmen still endure. These professionals especially appreciate the workability of fresh lime, and consider that a traditionally aged lime putty provides better performance either than a coetaneus lime putty or a powder lime. This better workability results into higher viscosity. The purpose of this thesis is to investigate the characterization of the limes at a microscopic level and the deformational behavior in fresh state, in order to be able to confront traditional knowledge with scientific research. At once, a second line of research has focused on verifying the applicability of various measurement tools to characterize lime putties and hydrated lime putties. In order to achieve the fulfillment of this thesis, some different limes available in the market, that could serve as an example of the various ways of manufacturing and producing this material, have been choosen. Right after, the following items have been studied: characterization using laser granulometry of the particles that make up lime, X-Ray Diffraction (XRD) and scanning electron microscopy; deformational behavior of limes after the measurement of viscosity has also been studied. Another important part of the research performed has focused on to discern how hydrated lime putties evolve in time and after stirring processes. The results of these works demonstrate that laser granulometry techniques and viscosity measurements can be applied as valid tools to characterize limes, whereas it is concluded that A[0001] parameter obtained from XRD is not valid to reckon the age of lime putty. The ability of powder lime to evolve increasing its viscosity and its thixotropic character after short periods of ageing in lime putty format has also been demonstrated. Regarding the qualities of traditionally aged limes putties, it has been stablished that they exhibit generally higher viscosities and smaller size particle distributions than hydrated lime putties. The evolution of lime putty aging process does not lead to better results, neither always nor indefinitely. Therefore, an aged lime putty is not necessarily better than a less aged lime .

    This paper analyzes a new semiphysiological ionic model, used recently to study reexitations and reentry in cardiac tissue [I.R. Cantalapiedra et al, PRE 82 011907 (2010)]. The aim of the model is to reproduce action potencial morphologies and restitution curves obtained, either from experimental data, or from more complex electrophysiological models. The model divides all ion currents into four groups according to their function, thus resulting into fast-slow and inward-outward currents. We show that this simplified model is flexible enough as to accurately capture the electrical properties of cardiac myocytes, having the advantage of being less computational demanding than detailed electrophysiological models. Under some conditions, it has been shown to be amenable to mathematical analysis. The model reproduces the action potential (AP) change with stimulation rate observed both experimentally and in realistic models of healthy human and guinea pig myocytes (TNNP and LRd models, respectively). When simulated in a cable it also gives the right dependence of the conduction velocity (CV) with stimulation rate. Besides reproducing correctly these restitution properties, it also gives a good fit for the morphology of the AP, including the notch typical of phase 1. Finally, we perform simulations in a realistic geometric model of the rabbit¿s ventricles, finding a good qualitative agreement in AP propagation and the ECG. Thus, this simplified model represents an alternative to more complex models when studying instabilities in wave propagation.

    Calcium alternans is a pro-arrhytmic cardiac dysfunction related to beat-to-beat changes in the amplitude of intracellular calcium transient, that typically occurs at rapid pacing rates. Although oscillations in sarcoplasmic reticulum (SR) content have been related with calcium alternans, the experimental appearance of alternans without these oscillations suggests that another mechanism related with refractoriness of SR calcium release might be key, at least, under certain conditions. We investigate how RyR2 refractoriness modulates calcium handling on a beat-to-beat basis using a numerical rabbit cardiomyocyte model. We find that a slow recovery from inactivation of the RyR2 might be crucial. On one hand, a steep relation between sarcoplasmic reticulum (SR) load and calcium release makes regular calcium cycling unstable at high SR calcium load and/or fast pacing rates, in agreement with previous explanation when RyR2 inactivation is not important. On the other hand, we show that calcium release can also depend strongly on the number of RyR2 ready to open if an important number of RyR2s inactivate after the release. This gives rise to a steep nonlinear relation between the calcium release and the level of recovered RyR2, so that a small change in the later produces big changes in calcium release. A conclusion of this result is that RyR2 refractoriness can be the main nonlinearity behind alternans even when alternation in SR-Ca load is present

    Despite the important role of electro-mechanical alternans in cardiac arrhythmogenesis, its molecular origin is not well understood. In this paper we want to study alternans that can be associated with alternations in the cytosolic calcium transient. To this end we study particularly, how a malfunction of Ryanodine Receptor (RyR) recovery time from inactivation may induce beatto- beat alternations in intracellular calcium concentration and how this could affect the stimulus propagation in inhomogeneous tissue, whose cells exhibit different calcium dynamics.

    Phase-2 re-entry is thought to underlie many causes of idiopathic ventricular arrhythmias as, for instance, those occurring in Brugada syndrome. In this paper, we study under which circumstances a region of depolarized tissue can re-excite adjacent regions that exhibit shorter action potential duration (APD), eventually inducing reentry. For this purpose, we use a simplified ionic model that reproduces well the ventricular action potential. With the help of this model, we analyze the conditions that lead to very short action potentials (APs), as well as possible mechanisms for re-excitation in a cable. We then study the induction of re-entrant waves (spiral waves) in simulations of AP propagation in the heart ventricles. We show that re-excitation takes place via a slow pulse produced by calcium current that propagates into the region of short APs until it encounters excitable tissue. We calculate analytically the speed of the slow pulse, and also give an estimate of the minimal tissue size necessary for allowing reexcitation to take place.

    Several series of experiments in stratified and in rotating/stratified decaying flows after a grid is used to stir the two layer stable fluid brine and fresh water set up. We measure by comparing the gained potential energy with the available kinetic energy AKE, the relative efficiency of mixing. The experiments in stratified rotating flows with grid driven turbulence were both periodic (quasi stationary) and non-monotonic (decaying) forcing. This thesis compares experimental, numerical and field observations on the structure and Topology of the Stratified Rotating Flows as well as their decay, the horizontal spectra changes appreciable with slopes from 1.1 to 5, but vorticity and local circulation, and also the initial topology and forcing of the flow. A detailed study of the vorticity decay and vortex and energy structure has been performed, the new results show that neither stratified nor rotating flows exhibit pure 2D structures. The work parameterizes the role of the Richardson number and the Rossby number, both in the experiments and in the ocean visualizations is very important. The conditions of vortex decay show the effects of the internal waves in the decay turbulent conditions both for stratified and rotating flows. The parameter space (Re,Ri,Ro) has been used to interpret many previously disconnected explanations of the 2D-3D turbulent behaviour. The comparison of numerical simulations with experiments has allowed implementing new theoretical aspects of the interaction between waves and vortices finding the surprising and very interesting result that these interactions depend on the level of enstrophy. This also leads to new ways of using multifractal analysis ad intermittency in ocean environmental observations. A large collection of SAR images obtained from three European coastal areas were used for routine satellite analysis by SAR and other sensors, which seem very important to build seasonal databases of the dynamic conditions of ocean mixing. The topology of the basic flow is very important and in particular the topology of the vortices and their decay which depends on ambient factors such as wave activity, wind and currents. We find more realistic estimates of the spatial/temporal non-homogeneities (and intermittency obtained as spatial correlations of the turbulent dissipation); these values are used to parameterize the sea surface turbulence, as well as a laboratory experiments at a variety of scales. Using multi-fractal geometry as well, we can establish now a theoretical pattern for the turbulence behaviour that is reflected in the different descriptors. Vorticity evolution is smoother and different than that of scalar or tracer density. The correlation between the local Ri and the fractal dimension detected from energy or entropy is good. Using multi-fractal geometry we can also establish certain regions of higher local activity used to establish the geometry of the turbulence mixing that needs to be studied in detail when interpreting the complex balance between the direct 3D Kolmogorov type cascade and the Inverse 2D Kraichnan type cascade.

    En Julio 2009, fuimos invitados a asistir al apagado de una cal cocida en un horno tradicional de principios de siglo, restaurado por los hermanos Cagni Mur! en 1997, en el marco de un curso organizado por el Forum Italiano Calce, en Zone (BS). Dicha cal fue apagada siguiendo tres métodos tradicionales: ordinario por aspersión, "grande aqua" y por breve inmersión. A lo largo de los distintos procesos de apagado, se realizaron medidas de temperatura mediante termopares y una cámara de termovisión. A partir de las diferentes muestras obtenidas de cal apagada, se procedió a la caracterización completa mediante diferentes técnicas instrumentales como, difracción de rayos X (DRX), fluorescencia de rayos X (FRX), análisis termogravimétrico (TG), superficie específica (BET) y tamaño de partícula por dispersión laser. También se estudio la morfología de las partículas mediante microscopia electrónica de barrido (SEM). Simultáneamente se han reproducido en laboratorio, distintos apagados de la cal viva de Zone, variando la proporción agua/sólido, y por tanto, variando la temperatura máxima conseguida, con el fin de disminuir la variabilidad del proceso tradicional y poder estudiar mejor únicamente el efecto de la temperatura de apagado. Los productos así obtenidos serán igualmente caracterizados con las técnicas citadas. El análisis de los primeros resultados nos permite avanzar que existen diferencias en la distribución del tamaño de partícula, así como en los productos de hidratación que se forman.

    This study demonstrates the feasibility of using a simple method to measure the resonant fundamental frequency for determining the MOE (dynamic Young’s modulus) of lime and cement mortars. The procedure follows the instructions stated in the UNE-EN ISO 12680-1 standard for refractory products although in this study the instructions are applied to standardized RILEM 4x4x16 cm test samples made of lime and cement mortars. The simplicity of the procedure as well as its correlation to other measured variables, suggest that it can be widely applied in studies about the evolution of the physical characteristics in lime mortars, such as mechanical strength, static Young’s modulus, carbonation depth, etc
