    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 Es ist möglich, auch in menschlichem Serum eine Anaphylatoxinbildung (AT) durch Kontaktaktivierung oder Kobragift zu induzieren. Wegen der geringen Mengen, die entstehen, muss das wirksame Prinzip vor dem biologischen Nachweis angereichert werden. Menschliches AT verhält sich in allen untersuchten Eigenschaften wie AT aus anderen Plasmaarten. Es unterscheidet sich von dem darmkontrahierenden Spaltprodukt aus der menschlichen Komplementkomponente C′3, das mithin nicht als AT angesprochen werden kann.

    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 Der zeitliche Verlauf von Chromosomenaberrationen inAllium cepa nach Bestrahlung in 5 sowie 53 mm Tiefe eines Plexiglasphantoms mit 136 „R“ schneller Elektronen von 14,2 MeV wurde bestimmt. Die beiden Bestrahlungstiefen ergaben, wie bereits früher festgestellt, qualitativ verschiedene Verläufe zwischen 0 und 27 Std. Durch Markierung mit H3-Thymidin wurden die Dauern der einzelnen Phasen des Zellzyklus und ihre relative Strahlenempfindlichkeit ermittelt. Bei 5 mm Bestrahlungstiefe wurde ein Wirkungsmaximum für G2-Zellen, bei 53 mm Bestrahlungstiefe ein solches für G2- und S-Zellen gefunden. Der Effekt wird diskutiert und eine Deutung vorgeschlagen.
    Notes: Summary Chromosome aberrations in seedlings ofAllium cepa have been scored at different times after irradiation. Equal doses (136 “R”) of 14,2 MeV electrons were given at 5 and 53 mm depth within a Plexiglas phantom. The frequency of aberrations showed one maximum for 5 mm, two maxim for 53 mm irradiation which could have been correlated to G2 cells resp. S and G2 cells using H3-Thymidine.

This macrocycle, having different substituents at the positionspara to the hydroxyl groups, is the first one of its type to be studied. The general conformation of this calix[4]arene is compared to similar symmetrical ones. Thetert-butyl groups are not disordered as is usual and toluene is retained between the macrocycles. Two calixarene molecules are positioned to permit atert-butyl group of one to be inside the cavity of the second to establish CH3-π interactions.

    Topics: Economics
    Notes: Summary The study is devoted to the theory of economic growth and its relevance to pure and applied theory. It is maintained that by trying to explain the development of the factors of production the theory of growth represents an important generalization of the static theory of general equilibrium. The main conceptual categories and specific methods of growth theory are shown to be the examination of the existence and stability of growth equilibrium and of comparative dynamics. As far as applied theory is concerned the principle conclusions are the following: economic models devised to explain a country's economic development should be based on the theory of growth rather than on an entirely Keynesian business cycle approach. This does not seem to be generally realised, since the majority of macro-economic models is of basically Keynesian nature. On the other hand the theory of growth needs to be supplemented by a theory of business cycles, because the actual economic development exhibits growth as well as fluctuations. Although great stress is laid on the essential role of the growth theory in any attempt to explain a country's economic development, it is doubted whether the theory can as yet be usefully applied to practical situations. There remain a number of unsolved problems (of measurement etc.) typically connected with the theory of economic growth. While this may, for the time being, prevent the theory from being put to practical use, it in no way affects its basic validity.

    Description / Table of Contents: Résumé La survie de l'œuf à la pupe de la mouche de la brousseMusca vetustissima Wlk., en conditions naturelles, a été examinée au cours des années 1987/1988 dans une région du sud est de l'Australie qui n'avait pas été colonisée par les bousiers exotiques. Dans les amas de bouses de détail contenant uniquement la faune autochtone, la survie de la mouche variait de 0,3 à 12,5%. L'addition de deux espèces de bousiers exotiqueEuoniticellus fulvus (Goeze) etOnthophagus taurus (Schreber) aux amas disposés dans les champs, en nombres comparables à ceux observés dans les sites de récolte, réduisait la survie des mouches entre 0,3 et 4,4%. La survie des mouches en présence de la faune indigène et exotique des bouses était suffisamment basse pour maintenir la multiplication des mouches au-dessous de leur niveau moyen de remplacement de 3% pour toute la saison. La dispersion étendue et l'établissement de bousiers exotiques dans le sud-est de l'Australie, à côté de la faune indigène, conduiront à la réduction à long terme du problème de la mouche de la brousse.
    Notes: Abstract Egg to pupal survival of bush fly,Musca vetustissima Walker, under field conditions was examined during 1987/88 in an area of south-eastern Australia that had not been colonised by exotic dung beetles. In pads of cattle dung containing only the native fauna, fly survival ranged from 0.3% to 12.5%. The addition of 2 species of exotic dung beetles,Euoniticellus fulvus (Goeze) andOnthophagus taurus (Schreber) to field pads, in numbers similar to those observed at the collection site, reduced fly survival to between 0.3% and 4.4%. Fly survival in the presence of the native and exotic dung fauna was sufficiently low to keep fly breeding below their mean replacement level of 3% for most of the season. Widespread dispersal and establishment of exotic dung beetles in south-eastern Australia, alongside the native fauna, should lead to long-term reduction of the bush fly problem.
