    Notes: Current filaments formed in the parameter regime of the low-temperature impurity impact ionization breakdown of p-germanium were investigated by measuring tunneling and point contact characteristics of a scanning tunneling microscope tip fixed at certain sample positions under variation of the sample voltage. The results clearly indicate that the tip current is determined by local potential variations which can be interpreted by a model for the filament taking into account the finite electric resistivity of the sample contacts. © 1996 American Institute of Physics.

    Notes: We present a procedure that locally determines the composition (from a given set of available materials) of a segmented or graded thermoelectric generator leg in order to maximize its output power to a matched load. The method is based on a new interpretation of the electrical output relation, which is organized to resemble a differential output power along the device coordinate. The procedure is applied to calculate the segment length and output power of a segmented bismuth-telluride/iron-disilicide based thermoelectric generator leg. © 1998 American Institute of Physics.

    Notes: An integrated dc superconducting quantum interference device (SQUID) magnetometer has been fabricated using a YBa2Cu3O7−x–SrTiO3–YBa2Cu3O7−x multilayer process. The magnetometer consists of a 8.3 mm×8.6 mm pickup coil coupled inductively to a small washer-type SQUID with 9 Ω bicrystal junctions via an integrated 101/2-turn input coil. Using simple direct-coupled read-out electronics with additional positive feedback, a noise level of 9.7 fT/(square root of)Hz at 1 kHz and 53 fT/(square root of)Hz at 1 Hz was measured inside a magnetically shielded room. Due to the low noise level biomagnetic heart and brain signals with high quality and the very weak signals of the peripheral nerve system were recorded. © 1996 American Institute of Physics.

    Notes: All strains of Salmonella enterica investigated were found to carry the Salmonella enterotoxin gene (stn) as determined by PCR and hybridization studies. However, when using CHO-K1 cells for testing the toxicity of the strains, not all strains showed a toxic effect (cell elongation) on the cells or did so only at a low level. The cultivation of Salmonella in contact with epithelial cells (IEC-6) led to an increase in the production of toxin. The stn gene expression was detectable with the help of the RT-PCR after 3 h of incubation. The RNA of the strains was isolated, transcribed into cDNA (with MMLV-reverse transcriptase) and amplified using PCR. The PCR products were separated electrophoretically using a polyacrylamide gel and detected by silver staining.

    Description / Table of Contents: Resumé. Nous avons analysé six cas de raccourcissement posttraumatique du péroné. Differents types de fracture et de traitement ont menés à cette situation, qui, cliniquement se caracterise par des douleurs au niveau de la cheville et une déviation en valgus et rotation externe du pied. Tous les péronés ont été corrigés par des osteotomies d’allongement (ORP), soit horizontalement ou en forme de ”z”. Nos résultats montrent que la réconstruction opératoire d’une mortaise élargie constitute une intervention relativement simple qui donne de bon résultats et qui peu ralentir ou même arrêter la progression d’une arthrose posttraumatique. En conséquence l’ORP devrait constituer le traitement de choix dans les cas de raccourcissement posttraumatique même si des signes de dégénerescence arthrosique sont présents.
    Notes: Summary. Relative shortening of the fibula may occur after any type of ankle fracture when the lateral malleolus is involved. Patients complain of pain and restriction of their daily and sporting activities. Clinically, there is valgus of the hind foot due to abduction and lateral rotation of the talus. The goal of treatment is to restore the initial length of the fibula by a horizontal or Z-osteotomy, which will also correct the malposition of the talus. This study shows that the operative reconstruction of a widened mortise is a relatively safe procedure, independent of the type of osteotomy used. Lengthening of the fibula is an important step in the treatment of the painful ankle when the fibula is short after trauma, even when degenerative changes of the joint are already present.

    Notes: Abstract One of the open questions regarding the adaptive response to ionizing radiation is whether it can be induced in G0 lymphocytes. In the majority of experiments in which an adaptive response in G0 lymphocytes was observed, the adapting dose was applied in vivo. In order to investigate whether there is some in vivo component of adaptive response, mouse splenocytes of the C57BL/6 strain were irradiated with 0.1 Gy x-rays either in vivo or in vitro, and their UV-light-induced unscheduled DNA synthesis (UDS) levels were determined autoradiographically. An augmented UV-light-induced UDS following an adapting dose applied in vivo has previously been described by several authors in splenocytes of C57BL/6 mice, indicating that the adapting dose enhanced the DNA repair capacity of lymphocytes. In the present investigation, however, no evidence of an adaptive response could be seen regardless of whether the adapting dose was given in vivo or in vitro. Those results present a further indication for the fact that the adaptive response to ionizing radiation is not always inducible, even in lymphocytes of an inbred mouse strain in which its existence has been reported before.
