    Symbiotic bacterium modifies aphid body color (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-11-26
    Description: Color variation within populations of the pea aphid influences relative susceptibility to predators and parasites. We have discovered that infection with a facultative endosymbiont of the genus Rickettsiella changes the insects' body color from red to green in natural populations. Approximately 8% of pea aphids collected in Western Europe carried the Rickettsiella infection. The infection increased amounts of blue-green polycyclic quinones, whereas it had less of an effect on yellow-red carotenoid pigments. The effect of the endosymbiont on body color is expected to influence prey-predator interactions, as well as interactions with other endosymbionts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsuchida, Tsutomu -- Koga, Ryuichi -- Horikawa, Mitsuyo -- Tsunoda, Tetsuto -- Maoka, Takashi -- Matsumoto, Shogo -- Simon, Jean-Christophe -- Fukatsu, Takema -- New York, N.Y. -- Science. 2010 Nov 19;330(6007):1102-4. doi: 10.1126/science.1195463.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Entomology Laboratory, RIKEN Advanced Science Institute, Wako 351-0198, Japan. t-tsuchida@riken.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21097935" target="_blank"〉PubMed〈/a〉

    Secondary ion mass spectrometry round-robin study of relative sensitivity factors in gallium arsenide (1998)
    Chichester [u.a.] : Wiley-Blackwell
    Surface and Interface Analysis 26 (1998), S. 144-154

    ISSN: 0142-2421
    Keywords: SIMS ; GaAs ; round-robin ; sensitivity factor ; Chemistry ; Polymer and Materials Science

    Topics: Physics
    Notes: Round-robin studies on relative sensitivity factors (RSFs) in secondary ion mass spectrometry (SIMS) were conducted using bulk GaAs samples uniformly doped with various impurity elements. A total of 31 laboratories participated in two round-robins. More than 30 sets of relative ion intensities were obtained for B, Si, Cr, Mn, Fe, Cu, Zn, In and Te in GaAs. The RSFs for both positive and negative ions were derived for several types of SIMS instruments. The effect of primary ion incident angle was examined using quadrupole-based instruments and found to be the determining factor of the instrumental dependence of RSF. © 1998 John Wiley & Sons, Ltd.

    Polymerization of tetrahydrofuran: By the system triethylaluminum/water. I. General kinetic studies (1967)

    Description / Table of Contents: Kinetische Untersuchungen über die Polymerisation von Tetrahydrofuran mit dem ternären Katalysatorsystem Al(C2H5)3/H2O/Epichlorhydrin bei 0°C wurden durchgeführt. Dabei handelt es sich um eine Stufenpolymerisation, d.h., die Wachstumszentren werden größtenteils während einer Induktionsperiode gebildet; im 2. Teil der Polymerisation haben die Zentren eine fast konstante Konzentration und wachsen ohne Kettenabbruch oder Übertragung.Unter Zugrundelegung dieses Polymerisationsmechanismus wurde die Konzentration aktiver Zentren [P*] aus der Menge und dem Molekulargewicht des Polymeren bestimmt. Während der 2. Stufe wurde [P*] proportional Al(C2H5)3 und Epichlorhydrin gefunden.
    Notes: Kinetic studies have been carried out on the polymerization of tetrahydrofuran with the ternary catalyst system Al(C2H5)3H2O-epichlorohydrin at 0°C. It has been found that this is a stepwise addition polymerization, i.e., the propagating species is formed mostly in an induction period and during the subsequent second stage of polymerization the propagating species of an almost constant concentration continues to grow without being interrupted by chain transfer or termination.Based upon the above polymerization mechanism, the concentration of propagating species, [P*], was determined from the amount and the molecular weight of polymer. [P*] in the second stage was found to be proportional to the amounts of Al(C2H5)3 and of epichlorohydrin.
