The far-field spatial distributions of high-order harmonics in an ionized medium have been investigated using a computer model that includes both the single atom effects and the collective effects of the medium. The results show that depletion of the non-linear medium due to ionization and radial phase variations across the gas jet cause broadening and complicated structures in the far-field spati
OBJECTIVE: To analyse the outcome of minor amputations (through, or distal to, the ankle joint) in patients with diabetes. METHOD: All diabetic patients in a defined population undergoing one or more minor amputation between 1982 and 2006 were investigated according to a standardised protocol and were followed until final outcome (healing or death). A total of 410 consecutive amputations in 309 p
In this paper, we propose to perform remote laser-induced fluorescence imaging for assessment of cultural heritage. The experiments are performed using the lidar system consist of frequency-tripled Nd:YAG laser at 355 nm with a spot size of ~4 cm diameter and the signal is collected using a coaxial 40-cm-diameter Newtonian telescope. The fluorescence light is focused into an optical fibre and guid
Objective: To investigate the impact of a reminder (i.e., a mailed letter or short telephone call) from the pharmacy to patients, compared with no reminder in a control group, on the pick-up rates of unclaimed e-prescriptions. Method: Patients, with e-prescriptions transmitted to four large community pharmacies in two counties in northern Sweden and remaining unclaimed after 4 weekdays, were rando
The standard procedure for photopatch testing includes 24-h occlusion of the allergen, followed by irradiation at 5 J/cm2 ultraviolet A (UVA). Due to the timing, a separate visit to the clinic is needed for UV irradiation. The aim of this study was to determine whether a reduction in occlusion time from 24 h to 1 h, in order to simplify the testing procedure, influences test results when photopatc
