    Notes: Lead-zirconate-titanate [Pb(Zr52Ti48)O3,PZT] thin films, 0.5 μm thick, were deposited onto Pt/Si substrate at room temperature using the radio frequency planar magnetron sputtering technique. A perovskite structure in the PZT thin film was obtained after the annealing processes. The annealing temperature varied from 650 to 750 °C in this experiment to find the optimized annealing temperature. Using x-ray diffraction analysis, the lowest full width of the half maximum (110) plane was 0.23° for the sample at 650 °C annealing temperature. The values of the remanent polarization Pr and coercive field Ec of the PZT thin film were 100 nC cm−2 and 0.6 kV cm−1, respectively, at 60 Hz. The measured pyroelectric coefficient in 0.5 μm thin films was 3.12×10−4 C/m2 K at 50 °C. Their dielectric constant and loss tangent were 494 and 0.072, respectively, at 1 kHz. The surface structure of the PZT thin film was examined using scanning electron microscopy and the grain size was in the range of 0.08–0.14 μm. © 2000 American Institute of Physics.

    Notes: The acidic ether fraction of methanol extracts from Cyperus rotundus L. (purple nutsedge) tubers contained inhibitory substances described hereafter as inhibitor β. Inhibitor β inhibited sprouting of excised C. rotundus buds and also the elongation of wheat coleoptiles. The inhibition of bud sprouting by inhibitor β was reversed by the application of N-6-benzyl adenine (BA). Applications of abscisic acid (ABA) also inhibited sprouting of the excised buds and this was similarly reversed by BA applications. Chromatographic evidence suggested that inhibitor β mainly consisted of phenolic materials and possibly ABA as a minor component. The role of BA in enhancing sprouting of C rotundus tubers is discussed.Inhibition des bourgeons de bulbes de Cyperus rotundus L. par I'inhibiteur β ou l'acide abscissique et réversion de ces effects par la N-6-benzyl adénineLa fraction éther acide d'extraits, par le méthanol. de bulbes de Cyperus rotundus L. contient des substances inhibitrices decrites ci-après comme I'inhibiteur β. Cet inhibiteur β a inhibé la germination de bulbes isolés de C. rotundus ainsi que l'élongation de coléoptiles de blé. L'inhibition de la germination des bourgeons par I'inhibiteur βété renversée par l'application de la N-6-benzyl adénine (B.A.). Des applications d'acide abscissique (ABA) ont également inhibé la germination de bourgeons isolés et cet effet a été lui aussi renversé par des applications de B.A. Les chromatogrammes suggèrent que l'inhibiteur β est principalement constitué par des composés phénoliques et peut-être par I'ABA comme composant mineur. Le rôle de la B.A. dans l'inhibition de la germination des bulbes de C. rotundus est discuté.Knospenhemmung der Knollen von Cyperus rotundus L. durch Hemmstoff β oder Abscisinsäure und die Umkehrung dieser Effekte durch N-6-BenzylmleninDie saure Fraktion aus methanolischen Extrakten von Cyperus rotundus L.-Knollen enthielten Hemmstoffe, die im folgenden als Hemmstoff β bezeichnet werden. Hemmstoff β hemmte das Sprossen isolierter C. rotundus-Knospen und die Streckung von Weizenkoleoptilen. Die Hemmung der Knospensprossung durch Hemmstoff β wurde durch An-wendung von N-6-Benzyladenin (BA) aufgehoben. Abscisinsäure (ABA) hemmte auch das Sprossen isolierter Knospen; durch BA wurde es auf ähnliche Weise aufgehoben. Der chromatographische Befund deutet darauf hin. Daß Hemmstoff β sich hauptsächlich aus phenolischen Verbindungen zusammensetzt und möglicherweise in gering-em Unfang ABA enthält. Die Rolle von BA auf die Förderung der Keimung von C. rotundus-Knollen wird diskutiert.

    Notes: Papaya seeds, which constitute 22% of the waste product from the papaya puree industry in Hawaii, were characterized in a preliminary study to evaluate their possible utilization. Oil was extracted from the seeds, and its fatty acid composition determined. Crude protein and crude fiber contents of the defatted meal were especially high, 40.0% and 48.9%. Benzylisothiocyanate content in the seed oil was 0.56% (w/w), and the benzylglucosinolate content in the seed meal was 1.0 (w/w).

    Notes: The effects of frozen storage and packaging methods on the oxidation of fatty acids and rancidity development in fresh-water prawn Macrobrachium rosenbergii were studied. The lipids of these fresh prawns contained 23% saturated, 46% monounsaturated, and 31% polyunsaturated fatty acids. The fatty acids, especially the unsaturated ones decreased during frozen storage for 6 months at -18°C, regardless of the packaging procedure employed. No objectionable rancid flavor was detected in these prawns during the 6-month frozen storage study.
