    Notes: A 48-channel platinum-foil bolometer system on DIII-D was installed to achieve better spatial and temporal resolution of the radiated power in diverted discharges. Two 24-channel arrays provide complete plasma coverage with optimized views of the divertor. The divertor radiation profile was measured for a series of radiative divertor and power balance experiments. A significant change in the magnitude and distribution of divertor radiation with heavy gas puffing was observed. Unfolding the radiation profile with only two views requires one to treat the core and divertor radiation separately. The core radiation is fitted to a function of magnetic flux and is then subtracted from the divertor viewing chords. The divertor profile is then fit to a 2D spline as a function of magnetic flux and distance from divertor floor. © 1995 American Institute of Physics.

    Suitable characters for selective breeding in Eisenia fetida (Oligochaeta) (1995)
    Springer
    Biology and fertility of soils 20 (1995), S. 53-56

    Notes: Abstract Selective breeding of invertebrates has been suggested by many but studied by few. The possibilities of improving characters like biomass, maturation time, coccoon production rate, and hatching success of cocoons for the earthworm Eisenia fetida were examined in the present study. The results showed that biomass, maturation time, and number of hatchlings could be successfully improved by selective breeding, although a concomitant tendency to a lower reproductive rate, as found in vertebrates, was observed. Other characters like cocoon production rate, hatching success, and number of hatchlings per cocoon also showed promising results.

    Wiederholte Leberresektion bei kolorektalen Lebermetastasen (1995)

    Description / Table of Contents: Zusammenfassung Für Patienten mit rezidivierten, resektablen kolorektalen Lebermetastasen besteht allein in der chirurgischen Entfernung die erneute Möglichkeit, über längere Zeit von ihrem Tumorleiden befreit zu werden. Bei fehlenden therapeutischen Alternativen mehren sich in den letzten Jahren die Berichte über wiederholte Leberresektionen. Wir haben in den Jahren von 1986–1994 bei 8 Patienten insgesamt 12 wiederholte Leberresektionen bei kolorektalen Metastasen jeweils in kurativer Absicht ausgeführt. Die primäre Leberresektion bei 4 synchronen und 4 metachronen Metastasen bestand 5mal in einer anatomischen Hemihepatektomie und 3mal in einer Segment- oder Bisegmentektomie. Das Intervall zwischen 1. und 2. Leberresektion betrug durchschnittlich 14 (4–23) Monate. Bei 2 Patienten wurden jeweils 4 leberresezierende Eingriffe wegen wiederholt aufgetretener Metastasen ausgeführt. Die Zeitintervalle zwischen 2., 3. und 4. Lebereingriff betrugen hierbei durchschnittlich 10 Monate. Wir verloren keinen Patienten während des Klinikaufenthaltes, die postoperative Komplikationsrate betrug 16%. Drei Patienten sind inzwischen nach durchschnittlich 28 (9–54) Monaten seit der letzten Leberresektion verstorben. Fünf Patienten leben durchschnittlich 14 (4–28) Monate, 3 davon tumorfrei und 2 mit Metastasenrezidiv in der Leber. Bei niedrigem Operationsrisiko ist die Mehrfachresektion kolorektaler Lebermetastasen durchaus gerechtfertigt, was sich in deutlich verlängerten Überlebenszeiten dieser Patienten im Vergleich zu denen mit unbehandelten oder lediglich regional therapierten Lebermetastasen ausdrückt.
    Notes: Abstract For patients with recurrent operable liver metastases from colorectal cancer operative resection is the only chance of getting rid of their tumorous disease for a longer time. As there are not therapeutic alternatives more and more authors are reporting on repeated resections of liver metastases. From 1986 to 1994 we performed 12 recurrent liver resections with curative intent in 8 patients suffering from liver metastases of colorectal cancer: 4 synchronous and 4 metachronous metastases were removed, the primary procedure being anatomic hemihepatectomy in 5 cases and segmentectomy or bisegmentectomy in 3 cases. The mean time interval between the first and the second resections was 14 (4–23) months. Two patients underwent 4 consecutive liver resections because of recurrent metastases. In these cases the interval between the second, third and fourth procedures was 10 months. The postoperative complication rate was 16% and not a single patient died in hospital. Three patients died an average of 28 (9–54) months after the last liver resection, and the other 5 patients are still alive after an average of 14 (4–28) months: 3 are free of tumor and 2 have recurrent metastases in the liver. Compared with untreated or only locally treated cases, patients in whom operative risk is low can achieve prolonged survival times after resections of colorectal metastases to the liver.

    Continuous fractionation of an ionene containing cycloaliphatic moieties and the dependence of the glass transition temperature on molar mass (1995)

    Notes: About 340 g of a cycloaliphatic ionene (see formula given in the introduction) were fractionated by a continuous counter-current extraction method (CPF). The efficiency of the separation was checked by viscometry and gel permeation chromatography (GPC). Ten different fractions with number average molecular masses between 16 000 and 29 000 D were obtained and their glass transition temperatures Tg determined by differential scanning calorimetry (DSC) for their bromide and tetrafluoroborate salts. No molecular weight dependence of Tg was found, in contrast to recently reported results with aliphatic ionenes, where  -  in case of the bromide  -  Tg increases with rising molecular weight.

    Synthesis and solid-state properties of comb-like ionenes (1995)

    Notes: A series of comb-like ionenes with aliphatic side chains of different length and organic main chain spacer groups of different size have been synthesized by the step-growth polymerization of long aliphatic chain-substituted diamines with α,ω-dibromoalkanes. Highly ordered films of layered structure have been obtained by solution casting. The long side chains crystallize with an interdigitating hexagonal packing perpendicular to the film plane. The perfection of the side chain packing is related to the size of the spacer group in the main chain as well as to the valence of the counterions, but also depends on the thermal history of the samples. It is in all cases comparable to the quality of aliphatic chain packing in LB multilayers of surfactants. The comb-like ionenes exhibit liquid-crystalline textures above their side chain melting transition.
