    The partitioning of carbohydrates and the biomass of leaves in Populus tremula L . canopy (1998)

    Notes: Abstract  This study was aimed at making a quantitative evaluation of the biomass, carbohydrates and mineral nutrients partitioning in the canopy of aspen (Populus tremula L.) growing in a forest stand. Tree canopy biomass was divided into ten equal horizontal layers and the material for the study was sampled from all canopy layers. The results indicated that the specific leaf mass and the dry matter content increased but the area of leaves decreased toward the top of the canopy. The content of the non-structural carbohydrates depended largely on the position of the leaves in the canopy and the N, P and K contents in the leaves, reaching a maximum in the upper canopy layers better exposed to light. Regression analysis showed a linear relationship between the leaf mass per area and the percentage of dry matter on the one hand and the content of carbohydrates, N, P and K in the canopy on the other.

    Element Separation in the Chromosphere Ionization-Diffusion Models for the FIP-Effect (1998)

    Keywords: Sun: abundances ; chromosphere ; solar wind
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Ionization-diffusion mechanisms to understand the first ionization potential (FIP) fractionation as observed in the solar corona and the solar wind are reviewed. The enrichment of the low-FIP elements (〈10 eV) compared to the high-FIP elements, seen in e.g. slow and fast wind or polar plumes, is explained. The behaviour of the heavy noble gases becomes understandable. The absolute fractionation, i.e. in relation to hydrogen, can be calculated and fits well to the measurements. The theoretical velocity-dependence of the fractionation will with used to determine the velocities of the solar wind in the chromosphere.

    Length of human C-bands in relation to the degree of chromosome condensation (1976)
    Springer
    Human genetics 〈Berlin〉 35 (1976), S. 107-111 
    Details
    ISSN: 1432-1203

    Topics: Biology , Medicine
    Notes: Summary The C-band length of human chromosome 1 in prophase and prematurely condensed interphase chromosomes is relatively shorter than in metaphase chromosomes. However, even in chromosomes with the same degree of contraction the absolute length of the C-band varies considerably. This allocyclic behaviour of human constitutive heterochromatin has to be kept in mind if C-bands of different individuals are compared.

    Sex Pheromone Components of Nettle Caterpillar, Setora nitens (2000)

    Notes: Abstract Gas chromatographic–electroantennographic detection (GC-EAD) analyses of pheromone gland extracts of female nettle caterpillars, Setora nitens, revealed four compounds that consistently elicited responses from male moth antennae. Retention indices on three fused silia columns (DB-5, DB-23, and DB-210) of two EAD-active compounds were almost identical to those of (E)-9-dodecenal (E9–12 : Ald) and (E)-9,11-dodecadienal (E9,11–12 : Ald), two pheromone components previously identified in congeneric Setothosea asigna. However, comparative GC, GC-EAD, and GC-mass spectrometry of extracted S. nitens compounds and authentic standards revealed that the candidate pheromone components were (Z)-9-dodecenal (Z9–12 : Ald) and (Z)-9,11-dodecadienal (Z9,11–12 : Ald). The two other EAD-active compounds in pheromone gland extracts proved to be the corresponding alcohols to these aldehydes. In field-trapping experiments in Tawau, Malaysia, synthetic Z9–12 : Ald and Z9,11–12 : Ald at a 1 : 1 ratio, but not singly, attracted male S. nitens. Attractiveness of these two aldehydes could not be enhanced through the addition of their corresponding alcohols. Whether these differences in pheromone biology and chemistry between S. nitens and S. asigna are sufficient to prevent cross-attraction of heterospecific males or whether nonpheromonal mechanisms are required to maintain reproductive isolation is currently being studied.

    Notes: Abstract Gas chromatographic–electroantennographic detection (GC-EAD) analyses of female nettle caterpillar, Setothosea asigna, pheromone gland extracts revealed seven antennally active compounds. Based on their retention indices on three fused silica columns (DB-5, DB-23, and DB-210), these compounds were hypothesized and, through comparative GC, GC-EAD and GC-mass spectrometry with authentic standards, confirmed to be Δ10-undecenal, dodecanal, (E)-9-dodecenal (E9–12:Ald), (Z)-9-dodecenal, (E)-9-dodecen-1-ol, (E)-9,11-dodecadienal (E9,11–12:Ald), and (E)-9,11-dodecadienol. E9–12:Ald and E9,11–12:Ald were most abundant in female S. asigna pheromone extracts. In field trapping experiments in Palembang, Indonesia, synthetic E9–12: Ald and E9,11–12:Ald at a 1:1 ratio, but not singly, attracted S. asigna males. Attractiveness of these two aldehydes could not be enhanced further through the addition of their corresponding alcohols and/or other aldehydic candidate pheromone components. Use of E9–12:Ald and E9,11–12:Ald for pheromone-based monitoring of S. asigna populations will require lure formulations that minimize pheromone degradation by ultraviolet radiation and atmospheric oxidation.

    Description / Table of Contents: Summary The reaction of 12 pyridine derivatives with alkaline tetraiodomercurate was investigated and the physical properties and composition of the products have been established. The majority of the studied derivatives yielded compounds of the composition B2HgI2 (B = pyridine), only the 2-amino- and 3-aminopyridine yielded products of the BHgI2 type. Conclusions with respect to the structure of di-iodomercurates have been drawn on the ground of conductometric, ultraviolet and infrared spectrophotometric investigations.
    Notes: Zusammenfassung Die Reaktionen von 12 verschiedenen Derivaten wurden untersucht und physikalische Eigenschaften sowie die Zusammensetzung geprüft. Die meisten Substanzen ergaben Verbindungen des Typs B2HgI2 (B = Pyridin), nur 2-Amino- und 3-Aminopyridin ergaben Verbindungen der Zusammensetzung BHgI2. Rückschlüsse auf die Struktur der Dijodomercurate wurden aufgrund von konduktometrischen, UV- und IR-spektralphotometrischen Messungen gezogen.

    Über Elektrolysen von Nitraten in Acetonitril (1958)

    Notes: Untersucht wurden die Anodenvorgänge bei der Elektrolyse von Silbernitrat und Cadmiumnitrat in Acetonitril an Pt-Elektroden. Bei der Elektrolyse von Silbernitrat in Acetonitril trat eine Braunfärbung auf, die auf die Bildung einer Verbindung zwischen Silber(II) und N2O5 zurückgeführt werden konnte. Durch Zugabe von Anilin wurde nachgewiesen, daß an der Anode intermediär das NO3-Radikal bzw. dessen Dimeres, das N2O6, auftritt. Zu dem gleichen Ergebnis führte die Elektrolyse von Cadmiumnitrat. Erschwert wurde die Klärung des Anodenprozesses einmal durch den Wertigkeitswechsel des Silbers und zum anderen dadurch, daß das an der Kathode abgeschiedene Cadmium mit der Cadmiumnitratlösung reagiert. Die verschiedenen Reaktionsmöglichkeiten in Zusammenhang mit den auftretenden Elektrolyseprodukten werden diskutiert.
