Purpose: Biokinetic and dosimetry studies in laboratory animals often precede clinical radionuclide therapies in humans. A reliable evaluation of therapeutic efficacy is essential and should be based on accurate dosimetry data from a realistic dosimetry model. The aim of this study was to develop an anatomically realistic dosimetry model for Brown Norway rats to calculate S factors for use in eva
Natural radiative lifetimes of 10 levels of singly ionized ytterbium have been measured with time-resolved laser spectroscopy. Free Yb+ ions were produced in a laser-induced plasma. A stimulated Brillouin scattering technique has been used to produce laser pulses as short as 1 ns for the excitation of short-lived Yb+ states. Pseudo-relativistic Hartree-Fock calculations, taking into account the co
This article aims to contribute to the critical examination of the notions of health and activity, and to discuss how these cultural and social constructs have impact on elderly people’s lives. An ethnographic perspective gives fruitful inputs to explore how old people deal with the image of old age as one of decay and decline, while they simultaneously relate to the normative idea of so-called su
Ion time-of-flight spectra, total and partial ion yield spectra were measured from the vapours of CsCl and CsBr, containing both monomer and dimer molecules. VUV radiation ranging from 7 to 20 eV was used, covering the valence ionization thresholds and the resonant excitations in Cs+. The electronic and nuclear relaxation processes in the caesium halide dimer molecules are studied, using the yield
Churches, geometry and nonsense: A critical reply on Erling Haagensens article “Churches, geometry and statictics” in META 2002: 2.
We consider a cooperative wireless network where a set of nodes cooperate to relay in parallel the information from a source to a destination using a decode-and-forward approach. The source broadcasts the data to the relays, some or all of which cooperatively beamform to forward the data to the destination. We generalize the standard approaches for cooperative communications in two key respects: (
Asymptomatic bacteriuria (ABU) is a common clinical condition that often leads to unnecessary antimicrobial use. The reduction of antibiotic overuse for ABU is consequently an important issue for antimicrobial stewardship and to reduce the emergence of multidrug resistant strains. There are two issues in everyday urological practice that require special attention: the role of ABU in pre-operative

To evaluate measurement properties of 2 brief outcome measures for carpal tunnel syndrome: the 6-item carpal tunnel symptoms scale (CTS-6) and the 2-item palmar pain scale (measuring severity of pain in the scar/palm and pain-related activity limitation). Our hypothesis was that the CTS-6 is responsive to change in symptoms after surgical treatment and the pain scale is a valid measure of surgery-
A polyacrylamide gel crosslinked with allyl-b-cyclodextrin can be used repeatedly for several weeks for the separation of DNA fragments, since bubbles are not generated during a run. Allyl-b-cyclodextrin can easily be synthesized in one step from allylglycidylether and b-cyclodextrin. The plate numbers for DNA fragments, up to about 1500 bp, are high: for the 21 separation of pBR322/HaeIII fragmen
Analysis of prospectively collected data in a national register.
PURPOSE: To evaluate the use of x-ray imaging performed with a high-power laser system in biologic and medical studies. MATERIALS AND METHODS: A compact terawatt laser system based on chirped pulse amplification in titanium-doped sapphire was used. X rays were generated by irradiating a high-atomic-number target (tantalum). RESULTS: When photons with an energy below 10 keV were removed with use of
Background Studies in many countries have reported higher lung cancer incidence and mortality in individuals with lower socioeconomic status. Methods To investigate the role of smoking in these inequalities, we used data from 391 251 participants in the European Prospective Investigation into Cancer and Nutrition study, a cohort of individuals in 10 European countries. We collected information on
