    Notes: Abstract Emissions of volatile organic compounds (VOCs) from sunflower (Helianthus annuus L. cv. giganteus) were measured in a continuously stirred tank reactor. The compounds predominantly emitted from sunflower were: isoprene, the monoterpenes α-pinene, β-pinene, sabinene, 3-carene and limonene, an oxygenated terpene, not positively identified so far and the sesquiterpene β-caryophyllene. Emission rates ranged from 0.8 x 10−16 to 4.3 x 10 −15 mol cm−2 s−1 at a temperature of 25°C and at a light intensity of 820 µEm−2 s−1. A dependence of the emission rates on temperature as well as on light intensity was observed. The emission rates of α-pinene, sabinene and thujene from beech (Fagus sylvatica L.) were also affected by temperature as well as by light intensity. Our results suggest that an emission algorithm for all compounds emitted from sunflower and beech has to consider temperature and light intensity simultaneously. The observations strongly indicate that the emissions of VOCs from sunflower and beech are in part closely coupled to the rate of biosynthesis and in part originate from diffusion out of pools. The emission rates can be described by an algorithm that combines the model given by Tingey and coworkers with the algorithm given by Guenther and coworkers after slight modification.

    Description / Table of Contents: Zusammenfassung Bei der Errichtung der Unterseebootbasen des Atlantikwalls an der Küste Frankreichs 1941–1944 waren Tausende von Fremdarbeitern eingesetzt worden. Bei systematischen Untersuchungen wurden Jahrzehnte nach dem Krieg Spätschäden am Hüftgelenk (Sklerosierung, Cystenbildungen, Destruktionsherde, Sequesterbildungen) festgestellt, als Dekompressionsfolgen von Unterwassertätigkeit (zu rascher Druckabfall und damit Freiwerden von N2 in Form von Gasblasen, ungenügende Ausschleusungsmaßnahmen, teils aus Unkenntnis, teils aus Kriegs- und Beschleunigungsgründen). Bei 220 Fällen früherer Caisson-Arbeiter, welche nach dem Kriege nie wieder eine solche Tätigkeit ausgeübt hatten, fanden sich 21 Hüftgelenksarthrosen.
    Notes: Summary Forced labor was used extensively by the Germans for the construction of submarine shelters in the ‘Atlantic Wall’ built along the French coast in 1941–1944. Several decades later, systematic investigations reveal a significant number with tardive decompression damage in the hip joint: bone sclerosis, pseudocyst formation, destructive lesions, sequestration. Records of 220 individuals employed in forced subaqueous work under inadequate decompression conditions show 21 cases of arthrosis of the hip joint.

    Description / Table of Contents: Zusammenfassung Aktuelle Standortbestimmung der Verwertbarkeit und Rentabilität dieser Biopsie an Hand von 110 Fällen (68 Männer, 42 Frauen). Die Methode zeichnet sich aus durch relativ einfache Ausführungen in geübten Händen und durch die Seltenheit von Komplikationen (4 Hämatombildungen, 2 Lymphfisteln, die sich spontan schlossen). Die beste Indikation gibt die Sarkoidose ab: positive Ergebnisse 62% und die Hodginerkrankung 41 %, dagegen nur begrenztes Interesse beim Bronchialkrebs: 25 %. Bei letzterem hat die Biopsie vorzügliche prognostische Bedeutung: die Feststellung von Scalenus-Lymphknotenmetastasen macht eine Probe-Thoracotomie überflüssig.
    Notes: Summary Useful applications and results of Daniels' biopsy are presented on the basis of 110 cases (68 males, 42 females). Although relatively simple to perform, the procedure requires special training. Complications were rare (four hematomas, two temporary lymphatic fistulas). The major indications were sarcoidosis (62 % positive results) and Hodgkin's disease (41 %). In bronchial carcinoma only 25 % of results were positive and the findings were primarily of prognostic value. Identification of scalene lymph-node metastases makes thoracotomy redundant.
