Slowing down of 1.3–3.5 MeV/u Fe, Kr and I ions in ten metals
Abstract Stopping powers for 1.3–3.5 MeV/u 56 Fe, 80, 84 Kr and 127 I ions in Mg, V, Fe, Co, Ni, Cu, Nb, Sn, Ta and Au have been determined by a transmission technique exposing the metallic sample foils to the direct ion beam. No previous data have been published for Mg, V, Fe, Co, Nb, Sn or Ta stopping media with these ion energies. The experimental results are compared with parametrizations of the stopping powers found in the literature (SRIM-2000 and Hubert’s parametrization). Discrepancies as high as 21 and 16% are observed for SRIM and Hubert’s parametrization, respectively. However, there is agreement between the present results and other experimental data available at corresponding i…
Interrelation of peptidergic innervation with mast cells and ED1-positive cells in rat thymus
The peptidergic innervation of rat thymus has been investigated by immunohistochemical methods, focusing on the spatial interrelationship of peptidergic nerve fibers with mast cells and macrophages in the rat. An antiserum directed against the protein gene product 9.5 (PGP 9.5) regarded as a pan-neuronal marker revealed a rich innervation, especially in the subcapsular cortex, in interlobular septa, and of the vasculature in the cortex and the corticomedullary boundary. A minor proportion of PGP 9.5-immunoreactive (ir) fibers supplied the thymic parenchyma. The main component of peptidergic innervation consisted of fibers costaining for tachykinins (TKs) and calcitonin gene-related peptide …
