    Notes: Abstract. A sensitive and selective adsorption stripping voltammetric (AdSV) method for the determination of antimony using chloranilic acid (2,5-dichloro-3,6-dihydroxy-1,4-benzoquinone) as complexing reagent is described. The conditions under which its species of both oxidation states, Sb(III) and Sb(V), can be detected have been established. Sb(III) can be adsorbed onto the hanging mercury drop electrode (HMDE) using an accumulation potential of +100 mV from hydrochloric acid (pH=3.0) solution. Sb(V) can be determined using an accumulation potential of −500 mV in HCl (pH=1.0) solution. The peak potentials in the stripping voltammograms are −400 mV for Sb(III) and −140 mV for antimony (V). The detection limits are 210 ng/L for Sb(III) with 5 min pre-concentration and 560 ng/L for Sb(V) with 10 min pre-concentration. The method is applicable to the trace analysis and speciation of antimony in water samples and phosphoric acid.

    Notes: Abstract A multidimensional stochastic model for describing the decay of excited nuclei is presented. The model takes into account the dynamics of thermal fluctuations of collective variables, the dissipation of the kinetic energy of collective motion, and the emission of light particles from excited nuclei. The potential energy of a deformed nucleus is calculated within the liquid-drop model with a sharp surface and within the finiterange-interaction model. The friction parameters are calculated on the basis of the one-body-dissipation model. The inertia parameters are found in the Werner-Wheeler approximation. The drift components of forces are determined in terms of the entropy of an excited nucleus. The latter in turn is computed within the Fermi gas approximation with allowance for the deformation dependence of the density-level parameter. The fission probability, the mean multiplicity of neutrons emitted prior to scission (prescission neutrons), and the variances of the mass distributions of fission fragments at the most probable kinetic-energy value are calculated on the basis of the model developed here and are compared with experimental data. The dependences of these quantities on the model parameters are considered in detail.

    Description / Table of Contents: Summary We present a case of a young man with an extensive mediastinal tumor and the unexpected histopathological diagnosis of allergic granulomatosis and angiitis (AGA, Churg-Strauss-syndrome). A 24-year old man was admitted to our hospital due to a massive mediastinal tumor which was already infiltrating the middle and the upper lobe of the right lung, the thymus, and the pericardial sac. The most likely diagnosis at CT was thymus carcinoma. For that diagnosis the en-bloc resection of the thymus and the middle lobe was performed and completed by a mediastinal lymphadenectomy. Parts of the upper lobe of the right lung and a 15×10cm part of the pericardial sac needed to be resected as well.  The definitive histopathological result did not confirm a malignant process. After extensive immunhistochemical and molecular pathological investigations the most likely diagnosis was allergic granulomatosis associated with angiitis. Further investigations led to the diagnosis of an atypical Churg-Strauss syndrome. The problems with the clinical, histological, and immunhistochemical diagnosis are discussed and the rare conditions of the disease represented.
    Notes: Zusammenfassung In der vorliegenden Kasuistik wird über eine ausgedehnte mediastinale Raumforderung berichtet, als deren Ursache sich eine allergische Granulomatose mit Angiitis (Churg-Strauss) herausstellte.  Ein 24-jähriger Mann wurde wegen einer großen mediastinalen Raumforderung mit Infiltration von Mittellappen, rechtem Lungenoberlappen, Thymus und Perikard operiert. Nach CT-Kriterien war ein Thymuskarzinom am wahrscheinlichsten. Es wurde deshalb die en-bloc-Resektion von Thymus, Mittellappen, Teilen des rechten Lungenoberlappens, einem ca. 15×10cm großem Perkardanteil und der mediastinalen Lymphknoten ausgeführt.  Das definitive histologische Ergebnis konnte nach immunhistochemischen und molekularpathologischen Untersuchungen einen malignen Prozeß jedoch ausschließen, als endgültige histologische Diagnose fand sich eine allergische Granulomatose mit Angiitis. Nach umfangreicher Differentialdiagnostik wurde die Erkrankung als atypisches Churg-Strauss-Syndrom klassifiziert.  Die schwierige klinische, histologische und laborchemische Differentialdiagnose und die Spezifität des vorgestellten Krankheitsbildes werden dargestellt.

    Notes: Aim: Zygomatic implants have been introduced for the rehabilitation of patients with severe bone defects of the maxilla. The soft tissue aspects of the palatal emergence situation have not been described yet. The aim of this study was to evaluate the incidence and clinical impact of possible periimplant alterations of zygomatic implants.Materials and methods: From 1998 to 2001 all patients with zygomatic implants were included into this study (24 patients, 37 zygomatic implants). One implant was lost in the loading phase giving a survival rate of 97%. Fourteen patients with 20 zygomatic implants fulfilled the inclusion criteria and were all available for the recall examination. Thirteen zygomatic implants were inserted in cases of severe maxillary atrophy, seven in cases of tumour-resection of the maxilla. Clinical examination and microbial analysis using a DNA probe was performed. The implants had a mean time in situ of 598 days (min: 326, max: 914).Results: Colonisation with periodontal pathogens was found at four of the 20 implants. A positive microbiologic result of the periimplant pocket and the maximum pocket probing depth were not statistically related. Nine of the 20 implants showed bleeding on probing, four of these had positive microbiologic results. At sites without bleeding on probing only negative microbiologic samples were found (p=0.026). The mean palatal and mesial probing depth was 1 mm deeper than at the vestibular and distal aspect. Thus at nine out of the 20 implants both, bleeding on probing and pocket probing depth 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:03036979:JCPE505:ges" location="ges.gif"/〉5 mm indicated soft tissue problems resulting in a success rate of only 55%. The patient's history (tumor versus atrophy) or smoking habits seemed not to have influence the situation.Conclusion: These soft tissue problems should be taken into account if zygomatic implants are considered as an alternative therapy option in the maxilla.

    Notes: Al0.5In0.5P/Ga0.5In0.5P superlattice structures have been investigated as multiquantum barriers (MQB) in 630 nm band laser diodes in order to reduce thermal current losses. By inserting an optimized MQB, we have succeeded in improving both threshold currents and characteristic temperatures of such devices. However, the optimized dimensions of the MQB found experimentally deviated strongly from those predicted theoretically, indicating that the commonly used theoretical description assuming effective mass approximation, electron wave interference, and using transfer matrix calculation is not adequate. © 1999 American Institute of Physics.
