The aim of this study was to use ultrasound imaging to re-investigate the anatomy of the lactating breast. The breasts of 21 fully lactating women (1-6 months post partum) were scanned using an ACUSON XP10 (5-10 MHz linear array probe). The number of main ducts was measured, ductal morphology was determined, and the distribution of glandular and adipose(More)
Technical applications of multifilamentary wires indicate that filaments are used in complex magnetic fields (a combination of non-parallel a.c./d.c, transverse and rotating fields)-carrying an a.c./d.c, transport current of various frequency. Furthermore, due to technical manufacturing processes the filaments are heavily distorted. Therefore, a numerical(More)

Today's health care institutions are being challenged to provide high quality health care in the most efficient way possible. One approach taken by many organizations has been the development of critical pathways in order to minimize delays in therapy, facilitate the best outcomes, optimize resources, and maximize quality. Opportunities exist for these(More)
Background. In this paper we describe the application of the ASTM committee E31 standard guidelines for implementing a model for a computerized patient record [1]. Sao Paulo University Hospital is updating its clinical information systems and we intend to use international standards to facilitate the implementation and the integration of the new system [2].(More)
Health-care professionals no longer have the option on whether or not to include patient health education into patient care. The U.S. Joint Commission on Accreditation of Health Care Organizations (JCAHO) requires that patient and family education is provided in specifically identified areas. In order for health providing institutions to be approved, these(More)
This paper presents the features of the MONITOR project. This project initiated by ESA / ESTEC aims to increase the knowledge of the ionospheric effects and its impact on GNSS systems during active periods of solar activity. It includes the deployment of a set of GNSS-based ionospheric monitoring receivers worldwide distributed, the development of specific(More)
