    Notes: Abstract  Seven synthetic graphite powders of different grade of purity were analyzed by means of INAA, WDXRF, EDXRF, DC-OES directly and using ICP-MS, ICP-OES, ETAAS and FAAS in combination with various sample preparation techniques. On the basis of a statistical evaluation of the results obtained, for the trace elements Al, Ca, Cr, Cu, Fe, Mn and Ni, reference values were established and, for the elements As, Co, Mg, Mo, Pb, Sb, Si, Sr, Ti, V, Zn and Zr, informative values are given. The analyzed reference materials are commercially available.

    Description / Table of Contents: Zusammenfassung Ziel der Untersuchung war die Darstellung von HR-CT-Befunden und ihrer therapeutischen Relevanz bei Verdacht auf angeborene Hörstörungen. An 96 jungen Patienten wurde überprüft, inwieweit die Felsenbein-HRT-CT-Befunde mit Ergebnissen funktioneller Tests übereinstimmten und welche therapeutischen Konsequenzen sich ergaben. Normale Funktions- und CT-Befunde zeigten 49 Felsenbeine (FB). Bei Schalleitungsschwerhörigkeit (41 FB) wurden Mißbildungen des Schalleitungsapparates (37 FB) bzw. entzündliche Veränderungen (3 FB) gefunden. Kombinierte Schwerhörigkeiten (18 FB) konnten zur Hälfte teilweise oder vollständig abgeklärt werden. Bei sensorineuralen Hörstörungen (82 FB) fanden sich 22 Innenohrmißbildungen, 3 Mittelohrmißbildungen, 55 Normalbefunde, ein Untersuchungsabbruch (2 FB). 1 Debiler wies eine Innenohrmißbildung, kontralateral entzündliche Mittelohrveränderungen auf. Eine Indikation zur gehörverbessernden Operation wurde an 23 FB gestellt, an 22 FB war sie kontraindiziert. Die CT war in 19 Fällen eine Voruntersuchung für ein Cochleaimplant. Bei den übrigen Patienten mit bilateralen Hörstörungen wurde die Therapie mit Hörgeräten fortgeführt. Die CT ist eine wichtige diagnostische Methode zur Abklärung und Therapieplanung bei Felsenbeinmißbildungsverdacht.
    Notes: Purpose: To demonstrate HRCT findings and their therapeutic relevance in suspected congenital hearing disorders. Material and Methods: It was checked in 96 young patients if HRCT findings of the temporal bone could explain functional findings. Furthermore, the therapeutic consequences were noted. Results: Normal CT and normal functional findings were obtained in 49 temporal bones (TB). In conductive hearing loss (41 TB), dysplasias of the conducting apparatus (37 TB) and inflammatory changes (3 TB) were found. Combined hearing loss (18 TB) was clarified completely or partially in half the cases. There were 22 dysplasias of the inner ear, 3 dysplasias of the middle ear, 1 abandoned examination (2 TB), and 55 normal CT findings in senorineural hearing disorders (82 TB). 1 retardate had a malformation of the inner ear and, contralaterally, inflammatory middle ear. In cases of vestibular disorders (24 TB), 14 malformations of the inner ear were detected. An indication for an operation was given in 23 TB. In 22 TB, it was contraindicated. The CT was one preliminary examination to a cochlea implant in 19 patients. The therapy was carried on with hearing devices in the other patients. Conclusion: HRCT is an important method in diagnosis and therapeutic planning of suspected malformations of the temporal bone.

    Description / Table of Contents: Zusammenfassung Bei bis zu 70% der Patienten mit septischer Infektion und Multiorganversagen kann sich im Rahmen der maschinellen Beatmung eine Critical-illness-Polyneuropathie (CIP) entwickeln. Das Krankheitsbild ist geprägt durch eine verzögerte Respiratorentwöhnung mit prolongierter Beatmungsdauer, schlaffe, distal betonte symmetrische Tetraparesen/-plegien, fehlende oder verminderte Auslösbarkeit von Muskeldehnungsreflexen sowie Muskel-atrophien. Der vorliegende Artikel beschreibt die klinisch-neurologische Symptomatik, den Krankheitsverlauf mit klinischem Outcome, typische elektrophysiologische Befunde, pathophysiologische Konzepte, Differentialdiagnosen und therapeutische Konsequenzen in Form einer Übersicht. Dazu wurden die Angaben in der medizinischen Literatur und in unserer Arbeitsgruppe erhobene Befunde ausgewertet, verglichen und aus neurologischer Sicht diskutiert. Auf der Grundlage dieser Befundkonstellation wird eine klinisch anwendbare Definition der CIP abgeleitet. Die Notwendigkeit der elektrophysiologischen Untersuchung bei der Diagnose und des Monitorings der CIP sowie der Differentialdiagnose wird hervorgehoben.
    Notes: Summary Critical illness polyneuropathy (CIP) may occur in up to 70% of septic patients and multiple organ failure patients. Typical clinical signs of CIP are the difficulty to wean the patient from artificial respiration, a symmetrical flaccid quadriparesis/-plegia that is more pronounced in the distal parts of the limbs, reduced or absent deep tendon reflexes, and muscular atrophy. This article describes and discusses the clinical and electrophysiological features and clinical outcomes, physiopathological concepts, therapeutic implications, and the complex differential diagnosis of CIP from a neurological point of view, focusing on disorders of the nervous system and myopathic abnormalities. The data available in the literature were reviewed and compared to our own findings in order to deduce a clinical definition of CIP. It is a particular aim of this work to emphasize the crucial importance of electrophysiological investigation and monitoring in the classification of the nature and extent of neuromuscular disturbances in critically ill patients.

    Notes: Abstract: We report the even parity J =4,5 autoionizing spectra of calcium below the 3d threshold, investigated by two-step laser excitation from the 3d4s metastables through the 3d4p , intermediate states and subsequent optogalvanic detection. The 3d4s states are populated by electronic collisions in a d.c. glow discharge sustained in a Ca heat-pipe. More than a hundred resonant transitions have been measured with an accuracy of for the narrow ones using standard laser calibration techniques. The high lying levels are assigned to all expected autoionizing series. Moreover, some levels are observed. The theoretical interpretation is achieved by a combination of the nearly ab initio eigenchannel R-matrix and multichannel quantum-defect (MQDT) methods as well as by an empirical determination of the MQDT parameters in the phase-shifted formulation. Theoretical energy level positions and excitation profiles are compared with the experimental data confirming the identification of the observed structures. Strong mixing between series is found, while the ones do not couple with the series. Further insight into the strong channel mixing in the studied energy range is provided by a comprehensive review of the excitation profiles in the vicinity of the 4p5p perturber as obtained from a number of intermediate levels used in the present and in earlier experiments. Systematic electron correlation trends for series of , and are discussed.

    Topics: Physics
    Notes: Abstract: We report a theoretical approach based on a combination of jj-coupled eigenchannel R-matrix and multichannel quantum-defect (MQDT) methods suitable to determine Raman couplings, dynamical Stark shifts and threshold-resolved ionization rates in heavy alkaline-earth atoms. These atomic parameters are needed to analyze the partial photoelectron spectra and the ionization dynamics of multiphoton processes in a perturbative treatment of the field-atom interaction to the lowest non-vanishing order of perturbation theory. Numerical results are presented in barium, pertaining to the experimental level scheme used by Wang, Chen and Elliott [Phys. Rev. Lett. 77, 2416 (1996)] to study coherent control through two-color interfering paths. Particular emphasis is given on the comparison of length and velocity formulations for the electric dipole operator.
