    Notes on the genus Mama Belokobylskij (Hymenoptera: Braconidae: Euphorinae), and on the use of monotype taxa (2004)
    In:  Zoologische Mededelingen (00240672) vol.78, 18-28 (2004) p.451
    Details
    Publication Date: 2007-01-18
    Description: The genus Mama Belokobylskij, 2000 (Braconidae; Euphorinae) is re-assessed and the type species is compared with three similar species: Microctonus cephalicus Provancher, 1886, Microctonus reclinator Ruthe, 1856, and Euphorus spiniscapus Muesebeck, 1936. The results are discussed in relation to the use of taxa based on one specimen (“monotype taxa”). Problems concerning our knowledge of important groups of Euphorinae are outlined. The context of the peculiarly tangled taxonomical situation, which this paper deals with, is considered to be widespread in parasitoid taxonomy, and should be borne in mind in current studies of parasitoid biodiversity assessment.

    Phylogeny and biogeography of the genus Taractrocera Butler, 1870 (Lepidoptera: Hesperiidae), an example of Southeast Asian-Australian interchange (2004)
    In:  Zoologische Mededelingen (00240672) vol.78, 18-28 (2004) p.383
    Details
    Publication Date: 2007-01-18
    Description: The genus Taractrocera is distributed throughout the Oriental and Australian Regions. It contains 16 species, of which two, T. fusca and T. trikora, are described as new in this paper. All species are briefly characterized and the new species are described in full. The phylogeny of the genus is inferred, based on an analysis of morphological and genital characters, both of males and females. The biogeography of the genus is discussed in relation to the phylogeny. The genus has an Australian origin. After some diversification in Australia it dispersed into Asia, in or before the Miocene. It dispersed in the reverse direction, probably before the late-Miocene emergence of the Banda Arc and the Moluccas, 5-6 Mya. Three species are adapted to high altitude, one in the Himalayas and two in New Guinea. Apparently the adaptations occurred independently in the two areas. In New Guinea the high altitude species may have simply been carried up by the Pleistocene and recent uplift of the mountains. Possibly helped by the lowering of the sea-level several times during the Pleistocene, one Australian species colonized some of the Lesser Sunda Islands relatively recently.

    Description: New and lesser-known amphipods of hard substrates in the Delta area of the Netherlands (Crustacea: Amphipoda: Gammaridea) The distribution of 27 new and lesser-known amphipod species of sublittoral hard substrates in the Delta area in the southwest of The Netherlands is described. Data from literature on these species are scarce and/or not readily available. They are supplemented with results from recent investigations of mainly sublittoral hard substrates. Of the 22 marine species only nine occur offshore as well as inshore. The others seem to be restricted to inshore man-made coastline protections. This probably reflects the scarcity of hard substrates further offshore. Four invasive species were recorded in the brackish and freshwater part of the Delta area, two of them of pontocaspian origin.

    De opmars van de wespenspin Argiope bruennichi in Nederland (Araneae: Araneidae) (2000)

    Publication Date: 2007-01-10
    Description: The expansion of the range of the spider Argiope bruennichi in the Netherlands (Araneae: Araneidae) Argiope bruennichi (Scopoli, 1772) is one of the biggest and most colourful spiders in Europe and therefore easy to recognise, even by non-specialists. The species has expanded its range in Germany and Belgium for several decades now and reached the south of The Netherlands in 1980. After the discovery of the first female in the south of the province of Limburg more specimens were found in this region in subsequent years. Later the species was discovered near Herkenbosch, about 30 kilometres to the north. Over the last years the expansion continued rapidly and now almost 300 records are brought together. The species has become widespread in the southern and eastern part of The Netherlands. In 1995 a leap of some 70 kilometres was made, from Limburg to the southern parts of the Veluwe. The years 1998 and 1999 were very good for Argiope, both with over 80 records per year. It is suggested that this expansion is related to the warm and sunny summers in the nineties.

    Nesten van de reuzenmier Camponotus ligniperda in het noordwesten van haar verspreidingsgebied (Hymenoptera: Formicidae) (2000)

    Description: Nests of the carpenter ant Camponotus ligniperda in the northwestern part of its range (Hymenoptera: Formicidae) Camponotus ligniperda (Latreille, 1802) is a rare ant species restricted to the eastern part of the Netherlands. Most records relate to a low number of workers. In this paper the species is reported for the first time from the province of Drenthe. Some ecological features of the groundnest are compared with the only other recent nest in the Netherlands. Both nests are located under a decidious tree which protects them from excessive precipitation. In contrast with reports from Germany and Sweden, nesting sites in buildings and houses are not known. It is suggested that the low chances for settlement in our country are due to the wet atlantic climate as well as competition with larger Formica species.

    Notes: Die Anordnung dient zur Messung von Dampfdruckerniedrigungen verdünnter Lösungen (10-3 Mol/l) insbesondere assoziierender Substanzen. Es wurde eine Meßanordnung entwickelt, in der die durch kleine Druckdifferenzen verursachte Ausbuchtung der Wölbung des Meniskus eines Hg-Manometers nach dem Prinzip eines Photometers lichtelektrisch mit einem Vakuumthermoelement gemessen wird. Die Anordnung gestattet unabhängig vom Gesamtdruck noch Druckschwankungen von 10-4 mm Hg zu messen.

    Notes: Unsere wichtigsten chemischen Großsynthesen gehen von Acetylen bzw. vom Kohlenoxyd-Wasserstoff-Gemisch aus. Die Arbeiten im letzten Jahrzehnt bezweckten, diese Rohstoffe unmittelbar aus dem Ferngas zu gewinnen. Von den entwickelten Verfahren verdient insbesondere das Sauerstoff-Verfahren Beachtung. Es liefert ein Synthesegas mit nur noch 0,2% Methan und ist unempfindlich gegen den im Ferngas vorhandenen organischen Schwefel. Eine etwa folgende Umsetzung des Kohlenoxydes mit Wasserdampf zu CO2 und Wasserstoff kann in unmittelbarem Ánschluß an der Kohlenwasserstoff-Spaltung vorgenommen werden, so daß kein neuer Dampfverbrauch auftritt. Während in der folgenden Arbeit über das Verfahren zur Verarbeitung des gesamten Ferngases auf Kohlenoxyd und Wasserstoff berichtet wird, wird in einer weiteren Arbeit die chemische Verwertung der einzelnen Bestandteile des Ferngases behandelt.

    Notes: Nach den verfügbaren amerikanischen Quellen wird zusammenfassend über die seit etwa 1940 in Amerika erreichten Fortschritte auf dem Gebiet der Sauerstoff-Erzeugung und -Anwendung berichtet, besonders über Versuche an Austauschböden und Trennkolonnen für kleinere, meist leichtbewegliche Anlagen, über die Mittel zur Kälteerzeugung, über die Herstellung und den Versand von flüssigem Sauerstoff sowie über die unmittelbare Erzeugung von hochkomprimiertem Sauerstoff für die Flaschenfüllung durch Verdampfung des flüssigen Sauerstoffs im Zerlegungsapparat. Weiter wird ein neuer Austauschertyp besprochen und auf neu erschlossene Anwendungsgebiete für billigen, mäßig reinen Sauerstoff hingewiesen.

    Notes: Bei Kohlenoxyd-Hydrierungen unter Drucken zwischen 300 und 1000 at und Temperaturen über 400° erwiesen sich z. T. sog. „kohlenoxydfeste“ metallische Werkstoffe, insbesondere Stähle mit mehr als 13% Chrom, für den praktischen Betrieb als ungeeignet, obwohl sie anscheinend von Kohlenoxyd nicht abgebaut wurden. Es wurden daher 20 derartige Stähle und 6 eisenfreie Metallproben gegenüber Wassergas bei 1000 at und Temperaturen zwischen 300 und 450° untersucht und aus den Ergebnissen Folgerungen für die praktische Verwendungsmöglichkeit im Apparafebau gezogen.

    Notes: Bis 1940 war die Anwendung hoher Vakua fast nur auf das Laboratorium beschränkt, in der Technik evakuierte nur die Röhrenindustrie bis auf Drucke von beinahe 10-7 mm Hg, aber es handelte sich auch hier meist nur um verhältnismäßig kleine Volumina. Die anschließende Entwicklung wurde durch mehrere Ereignisse besonders gefördert: durch die Konstruktion hervorragender Pumpen in Deutschland und Amerika, durch die Schaffung guter Gläser in Jena, durch die Erfolge der Vakuumdestillation von Fetten, Ölen und empfindlichen organischen Substanzen in England, Deutschland und später in USA, und schließlich durch das amerikanische Atombombenprojekt, wo bereits bei der Gasdiffusions- und elektromagnetischen Trennung der Uran-Isotope die ersten großen Vakuum-Probleme auftraten. Heute ist selbst die großtechnische Erzeugung von Hochvakuum zwischen -100° und + 1000° C ein untergeordnetes Problem der Verfahrenstechnik geworden.

    Notes: Es wird über Versuche mit zwei Ausführungen von Pilzglocken aus Porzellan berichtet, die in Rektifizierböden eingebaut waren. Wirkung, Druckverlust und Flüssigkeitsinhalt der Sälen wurden ermittelt. Um eine gute Wirkung zu erreichen, müssen die Einzelabmessungen des Bodens entsprechend gewählt werden. Auch der Einbau einer Staurippe erhöht die Bodenwirkung.

    Notes: Der im folgenden beschriebene Kolbenverdichter arbeitet mit ungeschmierten Kolben und Stopfbüchsen. Die Abdichtung wird durch Labyrinthdichtungen erreicht. Dadurch behält das verdichtete Medium die ursprüngliche Reinheit, so daß der Verdichter in der chemischen Industrie und der Lebensmittelindustrie da verwendet werden kann, wo völlig reine Druckluft gebraucht wird.

    Notes: In den letzten Jahren hat die Fluorchemie, insbesondere die verschiedener organischer fluorierter Verbindungen, erheblich an praktischer Bedeutung gewonnen. Da in einigen Veröffentlichungenz. B. DECHEMA-Werkstofftabellen 1948; ferner Ind. Engng. Chem. 39, 12a u. 91a [1947]. bereits auf die gute Eignung des Silbers als Apparatebauwerkstoff für technische Reaktionen mit Fluorverbindungen hingewiesen worden ist, seien nachstehend einige quantitative Angaben gemasht, die das Ergebnis einer 1944 laboratoriumsmäßig durchgeführten Korrosionsprüfung darsfellen.

    Notes: Die technisch-wissenschaftliche Forschung der letzten Jahrzehnte brachte eine Erweiterung und Vertiefung unserer Erkenntnisse über die beim gekoppelten Wärme- und Stoffaustausch sich abspielenden Vorgänge. Trotzdem blieben noch Fragen ungeklärt, deren erschöpfende Behandlung für die rechnerische Erfassung baispielsweise der Trocknungsvorgänge unerläßlich ist. Zu diesen Fragen gehört der Zusammenhang zwischen Luftzustand und Gutstemperatur während des Trocknens bei bestimmten Arten der Gasströmung. Im folgenden werden diese Verhältnisse untersucht, wobei sich eine gute Übereinstimmung zwischen theoretischen und experimentellen Ergebnissen ergibt.

    Notes: Die bisherigen Definitionen des Wirkungsgrades von Wärmeaustauschern konnten zwangsläufig nicht in jeder Hinsicht befriedigen. Es wird auch immer schwierig sein, einen Wirkungsgrabegriff auf energetischer Grundlage aufzustellen, solange der Wärmeaustauschapparat allein betrachtet wird, da sich Wärme- und Druckverluste jeweils verschieden auswirken. Daher sollte auch das Arbeitsverfahren, in das der Wärmeaustauscher eingeschaltet ist, mit in Betracht gezogen werden. Im folgenden wird gezeigt, daß sich dann ein auf energetischer Grundlage beruhender Gütegradbegriff schaffen läßt, der zwar von Fall zu Fall neu aufgestellt werden muß, dafür aber eine Reihe von Vorteilen für den Erzeuger und den Abnehmer von Wäreaustauschapparaten bietet.

    Notes: Der Auslaufbecher DIN 53211 ist ein einfaches, praktisch leicht zu handhabendes Betriebs-Gerät zur Beurteilung der Konsistenz besonders von Farben und Lacken. Die vorliegende Untersuchung zeigt, innerhalb welcher Grenzen der Auslaufbecher tatsächlich geeignet ist, ein zuverlässiges Maß für die Konsistenz mit ihren Nebenerscheinungen, z. B. für die Viskosität usw., zu sein. Der experimentelle Zusammenhang zwischen Auslaufzeit und Viskosität wird durch Versuche mit 11 Normalflüssigkeiten ermittelt. Die genaue Analyse der Versuchsergebnisse gibt einen interessanten Einblick in die Strömungsvorgänge bei diesem Gerät.

    Notes: Die Aufzeichnung polarographischer Kurven in Tintenschrift gestattet einfachstes Modellieren und Auswerten der Kurven. Für den Betrieb normaler Tintenschreiber unter Verstärkung der Elektrodenströme mittels Verstärker in Saugschaltung1 wurde während des Krieges ein vollelektrisch arbeitendes Zusatzgerät durchgebildet, in dem alle erforderlichen Schaltelemente und Verstellorgane zur Kurvenaufnahme untergebracht sind. Die einfach zu bedienende, robuste und universell verwendbare polarographische Meßeinrichtung läßt sich auch in technischen Betrieben zur Durchführung von Serienanalysen verwenden. Seine Wirkungsweise wird im folgenden unter Beifügung einiger charakteristischer Kurven erläutert.

    Notes: Vielen Betrieben steht Kühlwasser zur Verfügung, das reich an Carbonathärte ist und daher leicht Versteinungen der Leitungen hervorruft. Um diese Steinbildung zu verhindern, hat sich der Zusatz geringer Mengen an Natriumhexametaphosphat bewährt. Während man zur Prüfung der Brauchbarkeit von Zusätzen bisher einfache Becherglasversuche angestellt hat, haben die Verfasser ein geeignetes, im Laboratorium durchführbares Prüfverfahren entwickelt, wobei die wesentlichen betrieblichen Faktoren berücksichtigt werden können. Im folgenden wird diese Apparatur beschrieben und dann werden damit erzielte Versuchsergebnisse mitgeteilt, die mit den in der Praxis gemachten Erfahrungen gut übereinstimmen. In einem Anhang wird schließlich über Becherglasversuche mit organischen Zusätzen berichtet.

    Notes: In der vorhergehenden Arbeit1 war über ein Verfahren berichtet worden, nach dem aus Ferngas durch Totalspaltung mit Sauerstoff Synthesegas gewonnen werden kann. Das Ferngas enthält jedoch eine Reihe von wertvollen Bestandteilen, die für die Verarbeitung auf Synthesegas zu schade sind. Im folgenden wird beschrieben, wie diese Produkte zu isolieren sind und welche Möglichkeit für ihre Weiterverarbeitung gegeben ist. Dabei wird insbesondere das Sauerstoff-Verfahren besprochen, bei dem Methan und Sauerstoff erst nach vollendeter Mischung einer Flammenreaktion unterworfen werden, die durch Einspritzen von Wasser unterbrochen wird.

    Notes: Fehler in der Bemessung von Vakuumleitungen führen im chemischen Betrieb nicht nur zu einer Erhöhung der laufenden Kosten, sondern können auch Anlaß zu Qualitäts minderungen geben, da dann bei höheren Drucken und damit bei unzulässig hohen Temperaturen gearbeitet werden muß. Es werden daher im folgenden Richtlinien für die Bemessung von Vakuumleitungen aufgestellt und an H and eines Nomogrammes erläutert.
