Expectations and received knowledge by surgical patients.
OBJECTIVE Here, the aim is to compare surgical patients' knowledge expectations at admission with the knowledge they received during their hospital stay. DESIGN The study used a descriptive and comparative design. SETTING The study was conducted on surgical wards at one randomly selected university hospital in Finland. PARTICIPANTS The sample (n = 237) consisted of surgical patients (trau...
متن کاملIranian physicians\' knowledge about radiation dose, received by patients in diagnostic radiology
Background: Although ionizing radiation is widely used to diagnose many diseases, the relevant hazards are known to be as an important limitation of its application. It is believed that the awareness of ionizing radiation dose values is one of the main stages in patient's radiation protection. The purpose of this study has been to investigate the level of physicians' knowledge about radiation d...

The spectral branching behavior of the 2 × 2 operator matrix of the magneto-hydrodynamic α−dynamo is analyzed numerically. Some qualitative aspects of level crossings are briefly discussed with the help of a simple toy model which is based on a Z2−gradedpseudo-Hermitian 2× 2 matrix. The considered issues comprise: the underlying SU(1, 1) symmetry and the Krein space structure of the system, exc...

The distribution of emission measure, and of heating budget, among the loops in the corona. ABSTRACT The aim of this paper is to validate a methodology for connecting the emission measure of individual solar coronal loops to the integrated emission measure of the entire solar corona, and using this connection to deduce the energetic properties of the corona, and then to show how this methodolog...

Winds from accretion disks driven by the radiation and magnetocentrifugal force. ABSTRACT We study the two-dimensional, time-dependent hydrodynamics of radiation-driven winds from luminous accretion disks threaded by a strong, large-scale, ordered magnetic field. The radiation force is mediated primarily by spectral lines and is calculated using a generalized multidimensional formulation of the...
