New Perspectives in Rheoencephalography
One of the most important advances in biomedical engineering has been the ability to inspect inside the body without opening it. In this sense, rheoencephalography (REG) is an electromedical technique used to assess the cerebral blood flow (CBF) by noninvasive electrical impedance methods, using electrodes attached to the scalp surface. This technique was first proposed by Polzer and Schuhfried (1950), and emerged as an extrapolation of impedance plethysmography applied to the head. An electric current flowing through a biological tissue causes a potential difference between any pair of electrodes that can be measured. This potential difference depends on the amplitude of the injected curre…
Evaluation of a Real, Low Cost, Urban WSN Deployment for Accurate Environmental Monitoring
There are many areas where Wireless Sensor Networks (WSN) can offer innovative solutions for environmental monitoring applications and the meteorological community, but due to their complexity in terms of energy constraints and low performance devices, very few real deployments can be found. In this paper we will explain in detail the design, implementation and performance evaluation of a sparse WSN that has been working maintenance-free for over 12 months. The network has been designed for environmental monitoring purposes, and several motes, attached to lampposts, accurately measure the Temperature and Relative Humidity at various locations in a local street. Our contribution is an enhanc…
Fotosensibilización y fototerapia con furocumarinas: Un estudio mecano-cuántico.
La Fototerapia es uno de los campos de la Medicina que ha experimentado unmayor desarrollo en las últimas décadas, ampliándose cada vez más el rango deenfermedades que pueden ser tratadas de esta forma. Quizás esta terapia representacomo ninguna otra la combinación entre la Física (radiación electromagnética) y laQuímica (el fármaco empleado o fotosensibilizador) para combatir enfermedades.El objeto de la presente Tesis Doctoral es el estudio teórico de compuestosempleados como fármacos en la denominada terapia PUVA, denominadosfurocumarinas. El estudio teórico químico-cuántico de los estados electrónicosexcitados de estas moléculas permite hallar alguna de las claves del mecanismo deacción…
