Research on ecological design to enhance comfort in open spaces of a city (Valencia, Spain). Utility of the physiological equivalent temperature (PET)
For many years now, research has focused on issues concerning making cities easier to live in and some of the most important of these concern climatology and thermal comfort issues. There is also a growing awareness of the importance of open spaces and green areas, as key elements in providing opportunities for human interaction, leisure and physical exercise. They are important for all inhabitants, but particularly so for children and the elderly population. Of especial interest are the studies which have examined the interaction of comfort with the urban climate. This issue was studied throughout the twentieth century, but recently the role which can be played by biometeorological indices…
Mapas de resonancia magnética functional obtenidos con PC
Objetivos: El estudio de resonancia magnetica funcional (RMf) tiene una especial relevancia en el analisis de diversas activaciones cerebrales. En este trabajo se describe el desarrollo de un programa informatico para PC que analiza estas imagenes para obtener mapas de activacion funcional de una forma sencilla. Material y Metodos: Los mapas de activacion se basan en las diferencias temporales de oxihemoglobina en un plano tomografico. Para detectar estas diferencias se comparan las intensidades registradas repetidamente durante dos estados distintos del cerebro, control y activacion. Los experimentos se han realizado en un equipo de RM de 1,5 Teslas. Para comprobar el correcto funcionamien…
