    Description / Table of Contents: Zusammenfassung Bei 21 Patienten fand sich nach Resektion von Lungenmetastasen und befallener Brustwand unabhängig von der Grösse der Brustwandinfiltration eine mediane Überlebenszeit von 11 Monaten. Nur 1 Patient mit Hodenteratom-Metastasen überlebte 5 Jahre und ist tumorfrei. Die 30-Tage-Letalität betrug 0%. Hauptindikation sind Komplikationen, wie Exulceration und Schmerz. Trotz schlechter Prognose kann eine Lebensverlängerung bei verbesserter Lebensqualität erreicht werden. In seltenen Fällen ist nach Tumorreduktion bei chemotherapiesensiblen Tumoren eine Heilung möglich.
    Notes: Summary In 21 patients after combined chest wall and lung metastasis resection a median survival time of 11 months was found independent of the degree of the chest wall infiltration. Only 1 patient with metastasis from a testicular teratoma survived 5 years and is tumor free. There was no 30-day-lethality. The main indications are complications such as exulceration and pain. In spite of the poor prognosis a prolongation of survival time with improved quality of life may be achieved. In rare cases cure is possible by combined tumor reductive surgery and chemotherapy.

    Description / Table of Contents: Zusammenfassung Die Ergebnisse therapeutischer Massnahmen bei Lebermetastasen können nur unter Berücksichtigung des Spontanverlaufes dieser Erkrankung beurteilt werden. Dazu bedarf es einer Prognoseberechnung therapeutisch relevanter Gruppen. Für Patienten, die nach heute gültigen Kriterien für eine Therapie in Frage kommen, fand sich eine mediane Überlebenszeit von 11 Monaten und eine drei-Jahres-Überlebensrate von 17%. Hieran wird die Effektivität therapeutischer Verfahren zu messen sein.
    Notes: Summary The therapeutic results in treatment of liver metastasis can only be judged with regard to the natural history of the disease for which the prognosis of therapeutically relevant groups must be evaluated. The median survival time was 11 months and the probability of 3-year survival 17% for patients who today are potential candidates for the various therapeutic procedures available. These results must be taken into consideration as a measure of the effectiveness of the therapies applied.

    Notes: The mechanical behavior of polyurethane-poly(methyl methacrylate) interpenetrating polymer networks (PUR/PAc IPN's) was investigated. Stress-strain and impact resistance measurements were made on IPN's with a variable PUR content. The effect of the degree of crosslinking of each network on the mechanical properties was also studied. It appears that only the ultimate elongation varies largely upon changing the crosslink degree. The results are interpreted in terms of the contribution of each network to the mechanical behavior, but also by the interpenetration of both components and by the phase continuity of the PAc network.

    Notes: Star-shaped block copolymers were used as heat activated adhesives in glass to glass joints. The branches consisted in either AB or ABA poly(styrene-b-isoprene) block copolymers. Tensile shear strengths of simple lap joints were measured for star block copolymers differing in the length or in the number of branches. Values higher than those of the corresponding linear species were obtained. These results were related to the presence of chemical junction points created by coupling the linear copolymers.

    Description / Table of Contents: Investigation on the Thermal Decomposition of Ammonium Yttrium Halides. III. Ammonium Yttrium Bromide, (NH4)3YBr6The decomposition equilibria of NH4Br and (NH4)3YBr6 were determined by total pressure measurements. It was shown by high temperature X-ray patterns and DTA that (NH4)3YBr6 and YBr3 show phase transitions in the measured temperature region. An endothermic transition of YBr3 starts near 300°C and is very slow. By interpretation of the thermal decomposition of (NH4)3YBr6, the enthalpy of formation, and the standard entropy was derived. In the system NH4Br/YBr3 only the described phase (NH4)3YBr6 exists.
    Notes: Durch Gesamtdruckmessungen wurden die Zersetzungsgleichgewichte von NH4Br und (NH4)3YBr6 ermittelt. Hochtemperatur-Röntgenaufnahmen und DTA zeigten, daß bei (NH4)3YBr6 und YBr3 im untersuchten Temperaturbereich Phasenumwandlungen erfolgen. Eine endotherme Umwandlung von YBr3 erfolgt oberhalb von 300°C und verläuft sehr langsam. Die Auswertung der thermischen Zersetzung von (NH4)3YBr6 liefert die Bildungsenthalpie ΔHBo((NH4)3YBr6,f,298) = -402 ± 7 kcal/mol und die Standardentropie So((NH4)3YBr6,f,298) = 134 ± 9 cal/Kmol. Eine weitere komplexe Phase existiert im System NH4Br/YBr3 nicht.

    Description / Table of Contents: Thermal Behaviour of Li3MnO4. II. α- and β-Li2MnO3By thermal decomposition of Li3MnO4 we obtained two new forms of Li2MnO3: α-Li2MnO3 crystallizes due to Guinier-Simon photographs cubic face-centered with a = 4.092 Å, β-Li2MnO3 hexagonal with a = 4,93, c = 14.24 Å, c/a = 2.89. α-Li2MnO3 is paramagnetic with μ = 3,82 B.M. Below the Neel temperature (≈ 50 K) β-Li2MnO3 is antiferromagnetic. Effective Coordination Numbers, ECoN, are calculated and discussed.

Effektive Koordinationszahlen, ECoN, werden berechnet und diskutiert.

    Description / Table of Contents: Notice on the Magnetic Behaviour of Li3CrO4Li3CrO4, a smaragd green powder, is due to powder photographs (Guinier-Simon-technique) isotypic with orthorhombic HT—Li3PO4, a = 6.309, b = 10.851, c = 4.952 Å, Z = 4. Between 298 and 10K the Curie-Weiss-Law is obeyed with μ=1.60 B.M. and Θ=+10 K. Below 5 K ferromagnetism is observed. ESR measurements at 4.2 K and more pronounced at 1.8 K show anisotropy of the ligand field.
    Notes: Li3CrO4, ein smaragdgrünes Pulver, ist nach Guinier-Simon-Aufnahmen isotyp mit HT-Li3PO4, a = 6,309 Å, b = 10,851 Å, c = 4,952 Å, Z = 4. Zwischen 298 und 10 K wird das Curie-Weisssche Gesetz mit μ=1,60 B.M., Θ=+10K befolgt. Unterhalb von 5 K tritt überraschend Ferromagnetismus auf. ESR-Messungen bei 4,2 K und ausgeprägter bei 1,8 K zeigen eine Anisotropie des Ligandenfeldes.
