Investigation of the Segregation of Binary Mixtures with Iron-Based Particles in a Bubbling Fluidized Bed.

The characterization of the segregation phenomena in binary mixtures of solids with very different densities and/or particle sizes is highly relevant in many industrial processes. As a recent example, some advanced CO capture systems using fluidized beds include the separation by segregation of the functional materials. In this work, we have conducted mixing-segregation experiments with particles of iron ore (a typical oxygen carrier in chemical looping combustion systems) acting as jetsam, and glass beads (representing a lower density solid present in the bed) acting as flotsam, to measure solid concentration profiles at different fluidizing gas velocities and mixture compositions of different-sized particles.

Introducción: la desnutrición relacionada con la enfermedad (DRE) es un problema sociosanitario frecuente que afecta preferentemente a los mayores de 65 años, que aumenta la morbimortalidad y disminuye la calidad de vida.  Objetivo: estudiar la prevalencia de DRE en mayores de 65 años en diferentes centros sociosanitarios del Servicio Regional de Bienestar Social de la Comunidad de Madrid. Métodos: estudio transversal en 33 centros sociosanitarios de Madrid (6 centros de atención primaria [AP], 9 centros de mayores [CM], 9 hospitales [H] y 9 residencias [R]) seleccionados mediante muestreo polietápico.

Metabolic control and chronic complications during a 3-year follow-up period in a cohort of type 2 diabetic patients attended in primary care in the Community of Madrid (Spain).

Background: Our aim was to analyze both metabolic control and chronic complications of type 2 diabetes mellitus (T2D) patients regularly attended in primary care during a 3 years of follow-up in the Community of Madrid (Spain).

Methods: From 2007 to 2010 we prospectively included 3268 patients with T2D attended by 153 primary care physicians from 51 family health centers. An prospective cohort study with annual evaluation over 3 years to the same population was performed.
