    Notes: Abstract The Mössbauer effect studies of57Fe in the paramagnetic salt FeNH4(SO4)2·12 H2O reported byObenshain et al. were extended to higher values of the applied external magnetic fieldH a. The results are discussed in terms of the theoretical calculations given byWegener. The data can be fitted using a maximum internal fieldH max=(598±10) kOe and two atomic spin correlation times τc=2,4 · 10−9 sec andτ′ c=2,1 · 10−9 sec.τ c andτ′ c are independent ofH a and the temperatureT. It is assumed in the analysis that the distribution w(H) of the internal fields can be described by a continuous function of the Boltzmann factor type with two parameters. These two parameters are determined by the normalization and the macroscopic magnetization.

    Notes: Abstract The hyperfine-structure spectra of the 14.4 keVγ-ray of the nucleus57Fe in the spinel type ferrite (Li 05 + Fe 1.3 3+ Cr 1.2 3+ O 4 2− ) have been measured through the use of the Mößbauer effect. These measurements were performed on powder samples at different temperatures between 88 °K and 633 °K. For the Fe3+ ions at both the tetrahedral (A) and octahedral (B) sites at 88 °K the effective magnetic fieldH at the Fe nuclei is the same and equal to 504±4 kG. The temperature dependence ofH A however is different fromH B . Application of an external magnetic field of 20 kG shows that the sign ofH A is positive and the sign ofH B is negative. As the temperature is increased a considerable broadening of the magnetic hfs-lines (and especially of the outer pair of lines) is observed. No theoretical discussion directly applicable to these measurements is as yet available. In the paramagnetic phase a well resolved doublet is obtained. It appears that this doublet must be interpreted as a quadrupole splitting.

    Description / Table of Contents: Résumé Le champignon Lenzites trabea a été cultivé sur le bois de Pinus silvestris, qui, en conséquence, devient attractif pour le termite de Saintonge, Reticulitermes lucifugus var. santonensis. Le bois attaqué est soumis à une distillation par la vapeur d'eau et le distillat est extrait avec l'hexane. La saponification de cet extrait et la séparation des lipides non-saponifiables donnent un produit très actif dans des tests de choix et dans un essai quantitatif pour des “substances de pistage”. Par la chromatographie sur colonne de ces lipides on a obtenu deux fractions très actives. Une de celles-ci est semblable à la fraction active obtenue par une méthode analogue, à partir d'extraits d'ouvriers du Termite de Saintonge. La chromatographie en phase gazeuse démontre qu'une des fractions des lipides du bois peut contenir la substance de pistage, cis-3, cis-6, trans-8-dodecatrièn-1-ol, qui a été décrite par Matsumura en 1968. L'autre fraction se comporte différemment, non seulement en chromatographie sur colonne, mais aussi en chromatographie en phase gazeuse et sur couche mince. Néanmoins elle aussi est fort active dans des tests de choix et dans l'essai de pistage. Les résultats indiquent que la phéromone de pistage du termite de Saintonge est aussi présente dans le bois attaqué par le champignon, qui peut être considéré comme une source de nourriture du termite. En outre les résultats démontrent que ce bois contient au moins une autre substance très active.
    Notes: Abstract Column chromatography of the unsaponifiable lipids from pine wood, on which the fungus Lenzites trabea was cultured, yielded two well-separated fractions, which were highly active in choice tests as well as in a trail-following test with the termite Reticulitermes lucifugus var. santonensis (Feytaud). Thin layer and gas chromatography confirmed that these fractions contained distinctly different active compounds. Column chromatography of the non-saponifiable lipids of the worker termites yielded only one active fraction, which corresponded to one of the fractions obtained from the wood. These results are in agreement with the opinion of Smythe et al., (1967), that a trail-following pheromone may at the same time be a food attractant. Our data show, however, that the “food” contains more than one highly active trail-following substance. Comparison of gas chromatographic data showed that cis-3, cis-6, trans-8-dodecatrien-1-ol, described by Matsumura et al. in 1968, may be present in one of these fractions.

    Description / Table of Contents: Zusammenfassung Pseudocholinesterase-Varianten können heute ohne großen Aufwand routinemäßig bestimmt werden. Es wurde deshalb die Frage geprüft, ob dieser Polymorphismus in der Paternitätsbegutachtung verwendet werden kann. Wegen der ungünstigen Genverteilung ist nur in sehr wenigen Fällen eine zusätzliche Information zu erwarten. Stimmen Kind und fraglicher Vater indessen in einer seltenen Variante überein, so ist der Hinweiswert sehr hoch (Essen-Möller-Ansatz). Die Chance, von der Vaterschaft ausgeschlossen zu werden, liegt für zu Unrecht bezichtigte Männer bei etwa 1,5%. Dazu werden eigene Untersuchungen mitgeteilt.
    Notes: Abstract Today, pseudocholine-esterase variants can be routinely differentiated without very specialized technical equipment. Therefore this well known polymorphism should be taken into consideration in paternity cases. In view of the distribution of gene frequencies, however, additional information is to be expected in very few cases only. If child and suspected father have a rare variant in common the likelihood for this man to be the father is very high (Essen-Möller's formula). The chance for wrongly accused men to be excluded is in the range of 1,5%. Some own observations are discussed.
