    Notes: Abstract In Part 1 we obtained lower and upper bounds of the expressionf(M φ(x;α),M ψ(y;α))−M χ(f(x,y);α) by replacing the given sets(x)=(x 1,...,x n ),(y)=(y 1,...,y n ) by two suitably chosen sets ((u)=(u 1,...,u m ),(v)=(v 1,...,v m ), in general withm≥4. Now, in the case of upper bounds, the numberm will, under additional hypotheses, be reduced tom=3 (§ 4) and finally tom=2 (§ 5). Inequalities, complementary to the inequalities of Hölder and Minkowski and to another inequality are given as illustrations.

    Notes: Abstract The behaviour of an isolated impurity in a crystal undergoing a displacive phase transition is investigated in an exactly soluble spherical-like model. We find, depending on the parameter of the impurity, either a global phase transition at the bulkT c or a freezing-out of local order at a temperatureT c loc 〉T c driven by a soft local mode. We furthermore discuss the dynamic autocorrelation function of the impurity by introducing a phenomenological damping.

    Description / Table of Contents: Zusammenfassung Die gebräuchlichen Techniken zur Zucht von pflanzensaugenden Insekten an künstlichen Diäten können nur relativ kleine Populationen liefern. Darüber hinaus hat der manuelle Aufwand, der für die Unterhaltung laufender Kulturen verschiedener Versuchsgruppen erforderlich ist, Ernährungsversuche mit pflanzensaugenden Insekten begrenzt. Zur Verbesserung dieser Situation wurde ein automatisches Zuchtsystem für laufende Zuchten der Erbsenlaus an holidischen Diäten konstruiert. Dieses System besteht aus Gefrierkammern, Diätflaschen, Verteilernetz, Pumpen und Diätkammern. Diese letzteren sind Teflonscheiben mit Rinnen, die als Doppelspiralmuster in eine der Oberflächen eingegraben sind. Daraus wird ein membranbedeckter Kanal durch Überziehen der Doppelspirale mit Parafilm. Durch diese Kanäle wird dreimal die Woche Diät gepumpt. Ein programmierbarer Zeitgeber regelt das System über längere Zeit hin. Dabei lassen sich Eintritt, Dauer und Reihenfolge der Abläufe leicht programmieren. Nur einmal in zwei Wochen müssen leere Flaschen durch volle ersetzt und alte Diätkammern durch neue ausgetauscht werden. Blattläuse können an den im System angeschlossenen Diätkammern leicht beobachtet werden; ebenso gut können diese Kammern, wenn nötig, für eine Inspektion vom System abgenommen werden. Das hier beschriebene automatische Zuchtsystem besitzt grosse technische Vorteile für die Massenproduktion von saugenden Insekten. Der hier entwickelte Zeitgeber ist verwendbar für die Automation von Systemen, die zu komplex für konventionelle Zeitgeber sind, aber auch nicht die Kapazitäten eines Prozessrechners erfordern.
    Notes: Abstract Current techniques for rearing plant-sucking insects on artificial diets can support only relatively small populations. Moreover, the manual effort required to maintain continuous cultures of several experimental groups has limited nutritional research on plant-sucking insects. To alleviate these problems, an automated-rearing system was devised to maintain continuous cultures of the pea aphid, Acyrthosiphon pisum, on holidic diets. The automated system is comprised of freezers, diet bottles, distribution networks, pumps, and diet chambers. The latter are Teflon® discs with grooves cut in a double-spiral pattern on one face. A membrane-covered channel is formed by bonding Parafilm® over the double spiral. Diet is pumped through the channels of the diet chambers three times a week. A programmable sequence timer controls the system for extended periods of time. The occurrence, duration, and order of the sequences may be easily reprogrammed. Once every 2 weeks, the system requires replacing empty bottles of diet with full ones and exchanging new diet chambers for old ones. Aphids are easily inspected with the diet chambers connected to the system or, if desired, the diet chambers can be disconnected for inspection away from the rearing facility. The automated-rearing system described here should be a great technological asset for the mass production of haustellate insects. The timer developed for the system is applicable for the automation of systems that are too complex for conventional timers but do not require the capabilities of process-control computers.

    Notes: Abstract Earlier investigations are extended to inequalities with three means of the formf(M ϕ (x;α),M Ψ (y;α))−M χ (f(x,y);α)≧0 (I). Replacing the given basic sets (x)=(x 1,...,x n ) and (y)=(y 1,...,y n ) by two suitably chosen sets (u)=(u 1,...,u m ) and (v)=(v 1,...,v m ), lower or upper bounds on the left side of (I) can be obtained. In the case of upper bounds these inequalities are complementary to (I). In general, the numberm is not less than 4; it may be reduced under additional hypotheses. Some examples (inequalities complementary to some additive inequalities) are given.

    Notes: Abstract An airborne laser system for remote sensing has been developed and tested at flight altitudes from 500 to 1200 m. The system is based on two continuous-wave CO2 lasers (output 3 W), tunable to different wavelengths, and detects the laser radiation scattered back from earth by heterodyne reception. The feasibility of the heterodyne reception technique under aircraft environment conditions was demonstrated, and man-made SF6 clouds and different types of uncovered minerals were traced. The data obtained indicate that the measuring range of the system can be increased to satellite distance by using a larger telescope and a more powerful laser and by reducing the electrical bandwidth.

    Notes: Summary 1–3 major proteins considered as vitellins or yolk proteins are detected in mature eggs from differentDrosophila species by gel electrophoresis on gradient slab gels. Qualitative and quantiative differences are found even between closely related species. In heteroplastic transplantations, no correlation was found between the similarity or dissimilarity of the protein pattern on the one hand, and success of failure of egg development and vitellogenesis on the other hand.
