Abstract Aus Suszeptibilitätsmessungen für die Titelsysteme über einen weiten Zusammensetzungsbereich mit Hilfe der Faraday‐Methode geht hervor, daß die diamagnetischen Gesamtsuszeptibilitäten in den Bi‐BiC13 ‐Schmelzen mit steigender Temp. abnehmen, während in den beiden In‐Systemen kaum Temp.‐Abhängigkeiten existieren.
Background We evaluated the safety and efficacy of darbepoetin alfa (DA), an attractive alternative to recombinant human erythropoietin (rHuEPO) in managing renal anemia, in Japanese children with chronic kidney disease (CKD) on peritoneal dialysis (PD) and hemodialysis (HD), and not on dialysis (ND). Methods A total of 31 pediatric CKD patients (13 PD, 2 HD, and 16 ND) were enrolled. DA was administered biweekly intravenously (IV) or subcutaneously (SC) for PD or ND patients, and weekly IV for HD patients for 24 weeks. The target Hb was defined as 11.0 to B13.0 g/dl. In patients receiving rHuEPO, the initial DA dose was calculated at 1 lg DA for 200 IU rHuEPO. The initial DA
The amorphous structure of Se-GeSe2 alloys quenched from the melt was investigated by means of X-ray diffraction method. The structure factor a(K) and the radial distribution function (RDF) of the alloys were calculated from the intensity function I(K). The following conclusions are drawn from these results.(1) The interatomic distance and the coordination number of pure Se agree well with those of Henninger et al.(2) In the a(K) of 33.3 at% Ge alloy, there is a strong peak corresponding to the strongest reflexion of the crystalline GeSe2, which indicates the close relation between the amorphous and the crystal structure of GeSe2.(3) Interatomic distances of the first and the second nearest neighbours slightly depend on the alloy composition. The coordination number increases gradually from 1.9 for pure Se to 2.6 for 33.3 at% Ge with Ge concentration.(4) Spiral atomic chain in the crystal of pure Se and Se alloys seems to persist in their amorphous structures.
Simultaneous measurements of ionic and electronic conductivities around the stoichiometric composition have been carried out on liquid Sn–Se, Sb–Se and Bi–Se alloys by applying the residual potential theory. The ionic conductivity, σi, in liquid Sn–Se and Sb–Se alloys increases with increasing temperature, while, in liquid Bi–Se alloys, it decreases with increasing temperature. The isothermal σi in liquid Sn–Se and Sb–Se alloys at higher temperatures exhibits a minimum at the stoichiometric composition of SnSe and Sb2Se3, respectively, and, on the other hand, it shows a maximum at Bi2Se3 in liquid Bi–Se alloys. Values of σi at SnSe, Sb2Se3 and Bi2Se3 near the melting temperature are 7.40 Sm−1 at 1173 K, 0.448 Sm−1 at 893 K and 45.3 Sm−1 at 993 K, respectively, which are about two orders of magnitude smaller than the corresponding electronic conductivities, σe. The value of σi of liquid Bi2Se3, which is the largest among three liquids, is roughly comparable to that for ionic liquid alloys such as Ag and Tl-chalcogenides. In contrast, liquid Sb2Se3 indicates the smallest σi due to the strong covalent bonding between unlike atoms. The minimum of the σi-isotherm at SnSe and Sb2Se3 in liquid Sn–Se and Sb–Se alloys also reflect the covalent nature in these liquids.
We evaluated the prevalence and the types of infectious foci in oral as well as ear, nose, and throat diseases, and we examined incidence of renal involvement with active treatment for focal infection in children with Henoch-Schönlein Purpura. A total of 96 children who presented at Aichi Children's Health and Medical Center and were diagnosed as having HSP were evaluated for infectious foci in the ear, nose, throat, and oral cavities. Seventy-one of 96 children (74.0%) had some type of infectious lesion, such as sinusitis or tonsillitis, and the prevalence of sinusitis was the highest (51 cases, 53.7%). In 44 HSP patients without renal involvement at the first examination, the incidence of nephritis was lower (13.6%) than in previous reports (17–54%) due to our aggressive intervention for infectious foci.
