Evaluación del comportamiento energético de las estaciones depuradoras de aguas residuales: Una aproximación económica
2019
Las Estaciones Depuradoras de Aguas Residuales (EDARs) son una pieza básica del conjunto de infraestructuras urbanas, ya que son indispensables para garantizar la salud pública y del medio ambiente. Actualmente, en España existen aproximadamente 3.000 EDARs que tratan 4.700 hm3 de aguas residuales, de los cuales la mayor parte, un 55,8% y un 33,5% son vertidos a cauces fluviales y al mar, respectivamente, mientras que un 10,4% es reutilizado en la agricultura y el riego de jardines, y el 0,3% restante es infiltrado al suelo para la regeneración de acuíferos y otros fines. Según el destino del agua residual, la normativa en materia de aguas residuales urbanas y reutilización requiere el cump…

Innovative extraction and separation technologies to improve the recovery of microalgae nutrients and bioactive compounds with potential beneficial e…
2023
Las microalgas son ricas en una gran variedad de compuestos bioactivos, que incluyen proteínas, polifenoles, polisacáridos, pigmentos, minerales, vitaminas, etc., que pueden utilizarse o separarse directamente para obtener componentes de mayor valor. La extracción y la separación son pasos clave en la obtención y posterior procesamiento de los productos relacionados con las microalgas, representando las tecnologías innovadoras de procesado una estrategia innovadora y eficiente para mejorar la calidad de estos productos. Actualmente, las microalgas y sus compuestos (nutrientes, compuestos bioactivos, etc.) se utilizan como alimento y también con finalidades desde el punto de vista de salud, …

Multipactor radiation analysis within a waveguide region based on a frequency-domain representation of the dynamics of charged particles
2009
[EN] A technique for the accurate computation of the electromagnetic fields radiated by a charged particle moving within a parallel-plate waveguide is presented. Based on a transformation of the time-varying current density of the particle into a time-harmonic current density, this technique allows the evaluation of the radiated electromagnetic fields both in the frequency and time domains, as well as in the near- and far-field regions. For this purpose, several accelerated versions of the parallel-plate Green's function in the frequency domain have been considered. The theory has been successfully applied to the multipactor discharge occurring within a two metal-plates region. The proposed…

In vitro evaluation of glycol chitosan based formulations as oral delivery systems for efflux pump inhibition.
2017
Recently, we have reported that glycol chitosan (GCS) was able to reverse the P- glycoprotein (P-gp) efflux pump. The objective of the present study was to evaluate the potential of two GCS-based dosage forms (aqueous solution or nanoparticle suspension) for oral administration of the P-gp substrate Rho-123. A further aim of the present study was to assess the effect of the glycol chitosan-4-thiobutylamidine thiomer (GCS-TBA) on P-gp activity considering that the corresponding thiomer of chitosan series is a well-known P-gp inhibitor. Pre-treatment of Caco-2 cell monolayer with a GCS solution or GCS-based nanoparticles increased the absorptive transport of Rho-123 across the monolayer of 1.…
Ocular gelling microspheres: in vitro precorneal retention time and drug permeation through reconstituted corneal epithelium.
2008
Purpose: The model drug norfloxacin (NOR)was encapsulated into trehalose (TRH) and hydroxyethylcellulose(NAT) microspheres to obtain a novel gelling ophthalmic delivery system for prolonged release on corneal tissue. Methods: We assessed NOR release from microspheres, prepared by the emulsion-solvent evaporation method. A new in vitro tear turnover model, including inserts containing reconstituted human corneal epithelium (RHC), was designed to evaluate the TRH/NAT microspheres’ precorneal retention time. Bioadhesive properties of TRH/NAT microspheres were validated by using drug-loaded microspheres prepared with gelatine (GLT) commonly used as reference material in adhesion studies. Result…
An experimental campaign to investigate sustainability issues in Single Point Incremental Forming processes
2012
Sustainability issues are crucial topics in manufacturing and the environmental burdens reduction for processes is highly requested. In particular, the environmental sustainability evaluation for sheet metal forming processes is an widely investigated topic since there is still a lack of knowledge on modeling issues. The main tasks are related to a more efficient materials use and to energy savings. Moreover, forming technologies environmental impacts are essentially process-dependent. A deep analysis of the cause-effect linkages (between process and material parameters and energy consumption, for instance), within each process, would be necessary to properly model environmental impacts and…
