    Description / Table of Contents: Ein Integrationshandbuch im besten Sinne: Das Wissen um das Zusammenspiel von Microsoft Windows Server 2003, ADS, Windows XP Professional, Office XP/2003 oder Exchange Server ist sehr komplex. Administratoren, die nach einer Gesamtlösung suchen, stellen fest, dass es immens viele Informationen, Fehlerbeschreibungen, Service Packs, Patches und Hotfixes zu den Einzelprodukten gibt, aber keinen Lösungsansatz, der dieses Wissen bündelt und in Beziehung setzt. Anders dieses Buch: Schritt für Schritt wird ein Gesamtsystem implementiert, das nicht nur über einen kurzen Zeitraum läuft, sondern wartbar bleibt und später auf neue Versionen upgedated werden kann. Die 3. Auflage des Standardwerkes wurde aktualisiert und erweitert um Ausführungen zu Small Business Server, Windows Server 2003 R2, Windows Terminalserver, Access-based Enumeration und Best Practices zum Drucken im Netzwerk.

    Description / Table of Contents: Zusammenfassung Injektion verschiedener Dosen von Azadirachtin in Larven des letzten Stadiums von Epilachna varivestis führt zu folgenden Ergebnissen: Niedrige Dosen (0.1–0.2 μg) erzeugen keine Verminderung des Gewichtszuwachses, verhindern aber vollständig die Verpuppung. Bei etwas höheren Dosen (0.3–1.0 μg) tritt zusätzlich eine einheitliche Verminderung der Gewichtszunahme auf, die in diesem Bereich nicht dosisabhängig ist. Es wird vermutet, daß Azadirachtin in höheren Dosen bestimmte metabolische Prozesse in einer bisher unbekannten Weise beeinflußt. Es wird weiterhin gezeigt, daß nach Injektion höherer Dosen die für die Metamorphose wichtigen Speicherproteine im Fettkörper nicht oder nur unzureichend gebildet werden.
    Notes: Abstract Injection of the insect growth regulator azadirachtin into 40-h-old last larval instars of Epilachna varivestis (Mulsant) inhibited metamorphosis at doses lower than 0.3 μg. Various higher doses (0.3–1.0 μg) caused in addition weight gain reduction, whereas weight gain was almost entirely suppressed after injection of 2.5 μg. Histological and electrophoretical analyses showed that storage protein formation in the fat body, necessary for pupation, did not occur in higher dose treated (1.0 μg) individuals, but it was not affected by low dose (0.1 μg) treatment. It is assumed that azadirachtin causes metabolic defects at higher concentrations.

    Notes: Summary The nucleoside antibiotic nikkomycin has proved to be an effective inhibitor of chitin synthesis in the Mexican bean beetleEpilachna varivestis. Ultrastructural investigations show defects in the procuticular area after nikkomycin application which suggest the complete absence of chitin. A cuticle like this is inflexible and too brittle to satisfy its normal function as an exoskeleton. The individuals are not able to free themselves from the exuvia and finally die. Therefore nikkomycin seems to be a potential insecticide with high specifity.

    Notes: Summary In Rhapidostreptus virgator exocrine gland complexes are found in the anal valves of both sexes. Every gland complex consists of about 200 secretory units, each of which is comprised of four cells: two secretory cells, an intermediary cell, and a canal cell. The amount of secretion produced by these glands varies during the intermoult cycle: it is very small in freshly moulted individuals (postmoult phase), at a medial level during the following intermoult phase, and very large in the premoult phase. The secretion may be used to form the excrement clumps and above all to build the moulting chamber.

    Notes: Summary During each moult the anal glands in Rhapidostreptus virgator are partly dissolved and subsequently rebuilt and enlarged by embryonic cells within the anal sac epithelium. An embryonic cell undergoes two mitoses thus producing the four cells which are present in a glandular unit. During the genesis of the glandular units each of the latter secretory cells produce a ciliary process, which is believed to serve as a mould for the canal cell, which in turn secretes the cuticular efferent duct.

    Description / Table of Contents: Zusammenfassung 1. Die DiplopodenPolydesmus angustus undGlomeris marginata besitzen im vorderen Enddarm exokrine Drüsen, die als Pylorusdrüsen bezeichnet werden. 2. Die Pylorusdrüsen vonPolydesmus angustus sind Abkömmlinge von Enddarm-Epithelzellen, die sich in entsprechender Weise differenziert haben. Jede Zelle für sich ist sekretorisch tätig. 3. Im Gegensatz dazu sind die Pylorusdrüsen vonGlomeris marginata aus drei unterschiedlichen Zellarten zusammengesetzt: Sekret-, Übergangs- und Kanalzellen. 4. Die unterschiedliche Ausbildung und Größe der Pylorusdrüsen korreliert mit der Länge des Enddarms. 5. Die Pylorusdrüsen beider Diplopoden sezernieren ein Sekret, das sich auf der Enddarmintima als dünner Film verteilt. 6. Die Funktion der Sekretschicht wird darin gesehen, dab sie eine permeabilitfits-beeinflussende Wirkung auf der Enddarmintima ausfibt. Eine solche Schicht dtirfte somit eine wesentliche Rolle bei Rtickresorption wichtiger Stoffe aus dem Enddarmlumen spielen.
    Notes: Summary 1. Exocrine glands found in the anterior hindgut of the millipedesPolydesmus angustus andGlomeris marginata should be termed pyloric glands. 2. The pyloric glands ofPolydesmus angustus are appropriately differentiated hindgut epithelial cells. Every single cell shows secretory activity. 3. InGlomeris marginata the pyloric glands are composed of three types of cells: secretory cells, transitional cells, and canal cells. 4. The size and form of the pyloric glands are related to the length of the hindgut. 5. The secrete of the pyloric glands is dispersed on the hindgut intima as a thin film. 6. This secretion layer seems to influence the permeability of the hindgut and play an essential role in the reabsorption of water and other important compounds.

    Notes: Summary Within the optic lobe of adult Mexican bean beetles, Epilachna varivestis, three complex areas were detected that display elements with the morphological appearance of photoreceptors. Each of these complexes contains about eight cells that show fully differentiated rhabdomeres, screening pigments and other features typical of photoreceptors. It was shown that these areas originate from larval stemmata, which move into the depth of the head capsule during metamorphosis and are finally embraced by the outgrowing optic lobes. Although the function of these formations is not yet known, there are some indications that they may play a role in the entrainment of circadian clocks.

    Notes: Summary Plasmalemma-mitochondrial complexes (PMC) are known to be very active in water transport in different tissues. The PMC in the hindgut cells of the milliped, Scaphiostreptus sp., differ from those found in other transporting epithelia of hindguts; they are closely connected with cisternae of the endoplasmic reticulum. This arrangement is thought to be very efficient in ion and water transport.

    Description: Soil structure affects all soil functions especially those related to physical and biological processes. On the other hand, soil structure itself is directly affected by these agents. Hence, soil structure—from single pores to the pedon scale—is expected to reflect the capacity of soil to deliver ecosystem functions. We analyzed soil structure including its seasonal dynamics for two plots within the long-term fertilization experiment in Bad Lauchstädt (Germany). The different plots received very different amounts of mineral and organic fertilizers over a period of 106 y. The quantification of structural properties includes pore-size distribution and pore connectivity obtained by X-ray microtomography. We present a methodological approach for image analysis that allows to combine samples of different size and resolution to cover pores within one order of magnitude in diameter. The results for the different plots obtained in spring and summer are compared. We found that the enormous difference in energy input only affects the structure of the topsoil (Ap horizon) towards a higher porosity and pore-network connectivity and in terms of an increased resilience after tillage. However, the structural properties of the subsoil below the plowed horizon (Ah horizon) are not affected. We hypothesize that the structure of the subsoil reflects soil formation over much longer time scales, it allows for an increased turnover of soil organic matter, and it is rather stable at the time scale of the fertilization experiment.
