    Notes: Abstract Rates of ovarian development in relation to temperature were determined for autogenous females of the screw-worm fly, Chrysomya bezziana. Percentage durations of the different ovarian stages (scaled 2–10) were estimated on the basis of observed lengths of the developing oocytes. Mean durations (h) of each ovarian stage was determined at 20, 25, 28 and 35°C. A model of ovarian development rate (%/d) in relation to temperature (T) is presented, the fitted curve being give by R(T)=EXP (−2.73+0.362T−0.0055T2).

    Notes: Zusammenfassung Viscotoxin B, ein basisches Peptid mit Disulfidgruppen, zeigt in der Hämolyse den gleichen synergistischen Effekt mit Phospholipase A wie der direkt lytische Faktor des Kobragiftes. Dieses Ergebnis stützt die Hypothese, dass Zellmembranen durch Reaktionen ihrer Protein-SH-Gruppen so verändert werden können, dass Phospholipase A sonst unzugängliche Membranphospholipide angreift.

    Notes: Zusammenfassung Durch Behandlung mit Glutardialdehyd wirdNaja-naja-Gift weitgehend entgiftet. Einzeldosen bis zu 20 mg pro Kaninchen können ohne Nebenwirkungen injiziert werden. Durch Immunisierung von Kaninchen wird eine gute Antikörperbildung gegenNajanaja-Gift — und vor allem auch gegen die niedermolekularen Toxine — erzielt.

    Description / Table of Contents: Résumé L'effet de la privation de lieu de ponte a été étudié en comparant les pontes de femelles isolées ayant formé leurs œufs mûrs dans les 24 heures précédentes, à celles de femelles ayant atteint leur maturité sexuelle 8 jours avant. La rétention ovocytaire est provoquée en faisant consommer aux femelles de cette espèce anautogène différentes quantités d'aliments riches en protéines. La ponte de femelles dont le contingent total de leurs ovocytes s'est développé, — c'est-à-dire 260 —, après consommation ad libitum de foie de mouton pendant 48 heures, a été comparée à celle de femelles ayant formé 190 ovocytes mûrs après ingestion d'une quantité limitée de jus de foie. Dans des expériences sans choix, les femelles isolées de différences catégories ont eu accès pendant 4 heures au substrat de ponte trempé: 1) dans du jus de foie, 2) dans du jus dilué 16 fois, 3) dans du jus de foie non dilué mais contenant NaCl (inhibiteur de la ponte) à la concentration de 2 M. Le jus non dilué a provoqué une forte stimulation, induisant la ponte de 80% des femelles. Le jus dilué et celui contenant NaCl n'ont induit la ponte que de 40% des femelles avec des niveaux de stimulation bien plus faibles. La date d'introduction du lieu de ponte et le taux de rétention des ovocytes mûrs n'ont eu auçun effet sur la proportion de femelles réagissant à ces 3 types de stimulation.
    Notes: Abstract Oviposition by Lucilia cuprina Wiedemann (Diptera, Calliphoridae) was examined in relation to period of oviposition site-deprivation and egg-load. Effects of oviposition site-deprivation were examined by comparing oviposition performance of individual females that had matured their batch of oocytes within the previous 24 h with that of females which had reached ovarian maturity 8 days previously. Egg-load was manipulated by causing females of this anautogenous species to consume different amounts of protein-rich material. In no-choice experiments, individual females of the different categories were given access for 4 h to oviposition substrate, soaked with (i) liver exudate, (ii) the exudate diluted 16-fold or (iii) the undilated exudate containing the oviposition deterrent sodium chloride at a concentration of 2 M. These solutions elicited oviposition from different proportions of females, but neither these proportions, nor the interval between introduction of the oviposition site and the initiation of oviposition, was significantly affected by the period of oviposition site-deprivation or the number of eggs matured by the females.

    Description / Table of Contents: Zusammenfassung Die Moore-Penrose verallgemeinerte Inverse einer Matrix ist sehr wichtig für die Anwendung aus der Sicht neuerer Entwicklungen in Regelungs-, Filter- und Schätz-Theorie und Zeichenerkennung. In der bisherigen Literatur scheint die zur Herleitung der verallgemeinerten Inversen verwendete Theorie die Grundeigenschaften der verallgemeinerten Inversen im Dunkeln gelassen zu haben. Diese Arbeit verwendet zur Herleitung der verallgemeinerten Inversen die klassische Minimisierungstheorie, welche allgemein bekannt ist und den Vorteil hat, daß die Anwendung klar als Teil der Herleitung erscheint. Die Ableitung liefert zwei simultane Matrixgleichungen, von denen gezeigt wird, daß sie äquivalent zu den vier Gleichungen sind, die Penrose für die Definition der verallgemeinerten Inversen verwendet. Diese zwei Gleichungen ermöglichen die direkte Berechnung der verallgemeinerten Inversen einer Matrix ohne zu gebräuchlichen Iterationsverfahren Zuflucht zu nehmen.
    Notes: Summary TheMoore-Penrose generalized inverse for the matrix, in the light of recent developments in control, filtering, estimation theory, and pattern recognition, has been shown to have a great deal of importance as far as applications are concerned. In the previous literature, the theory used to derive the generalized inverse seems to have obscured the fundamental properties of what the generalized inverse is. This paper gives an alternate method of deriving the generalized inverse using classical minimization theory which is familiar and has the advantage that the application of the generalized inverse is made clear as a part of the development. This derivation results in two simultaneous matrix equations which are then shown to be equivalent to the four equations used byPenrose to define the generalized inverse. These two equations make possible the direct calculation of the generalized inverse of matrix without resorting to conventional iterated computational schemes.

    Notes: Zusammenfassung Analoge des Eledoisin-Oktapeptides 4–11, die Hydrazid-Komponenten enthalten, sind durch Aminopeptidasen nur bis zur Heterobindung abbaubar. Sie werden wesentlich langsamer als die native Sequenz bzw. nicht durch Organhomogenate inaktiviert, wenn die Substitution im N-terminalen Bereich erfolgt. Mögliche sterische Veränderungen des Peptids durch eingebaute Fremdbausteine sind diskutiert.
