    Notes: [Auszug] To detect oestrogenic activity it was necessary to inject the extract from a large volume of sheep urine, an injection of 0-1 ml. of the final oily extract corresponding to as much as 70 ml. of urine. Since the usual extraction methods for oestrogen, including that used1, would be expected to ...

    Extraction efficiency determinations of labeled systemic parathion residues (1973)
    Springer
    Bulletin of environmental contamination and toxicology 10 (1973), S. 140-144

    ISSN: 1432-0800

    Notes: Summary These results demonstrate the total reliability and efficiency of the Polytron extraction method. Differences in recovery of the Polytron extraction method and the soxhlet method were small, but differences in extraction times were considerable. The only limiting factor in the number of residue samples extracted by the Polytron would be those imposed by limitations in associated glassware.

    Conservation of intron position indicates separation of major and variant H2As is an early event in the evolution of eukaryotes (1990)
    Springer
    Journal of molecular evolution 30 (1990), S. 449-455 
    Details
    ISSN: 1432-1432
    Keywords: Histone H2A ; Histone variant ; Intron position ; Drosophila ; Tetrahymena
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Genomic clones ofDrosophila andTetrahymena histone H2A variants were isolated using the corresponding cDNA clones, (van Daal et al. 1988; White et al. 1988). The site corresponding to the initiation of transcription was defined by primer extension for bothDrosophila andTetrahymena genomic sequences. The sequences of the genomic clones revealed the presence of introns in each of the genes. TheDrosophila gene has three introns: one immediately following the initiation codon, one between amino acids 26 and 27 (gln and phe), and one between amino acids 64 and 65 (glu and val). TheTetrahymena gene has two introns, the positions of which are identical to the first two introns of theDrosophila gene. The chicken H2A.F variant gene has been recently sequenced and it contains four introns (Dalton et al. 1989). The first three of these are in the same positions as the introns in theDrosophila gene. The fourth intron interrupts amino acid 108 (gly). In all cases the sizes and the sequences of the introns are divergent. However, the fact that they are in conserved positions suggests that at least two of the introns were present in the ancestral gene. A phylogenetic tree constructed from the sequences of the variant and major cell cycle-regulated histone H2A proteins from several species indicates that the H2A variant proteins are evolutionarily separate and distinct from the major cell cycle-regulated histone H2A proteins. The ancestral H2A gene must have duplicated and diverged before fungi and ciliates diverged from the rest of the eukaryote lineage. In addition, it appears that the variant histone H2A proteins analyzed here are more conserved than the major histone H2A proteins.

    Multivariate analysis of tree height increment on meteorological variables, near the altitudinal tree limit in northern England (1974)
    Springer
    International journal of biometeorology 18 (1974), S. 199-210

    ISSN: 1432-1254

    Notes: Abstract The relationships between height increment of Scots pine (PINUS SYLVESTRIS L.), birch (BETULA PUBESCENS Ehrh.) and rowan (SORBUS AUCUPARIA L.) during one growing season to meteorological variables at 580 m above sea level in the northern Pennines were previously examined using orthogonalized regression analysis. The paper describes methods made to improve the efficiency of the models. Values of principal components of the meteorological variables of the current and preceding sets were associated with 76.5, 60.4 and 75.9 percentage of variability respectively, showing an improvement by allowing for lag effects in this way. Efficiency of using values of the original variables, with those of the preceding set, or with curvilinear terms, was generally less. Variation of response during the season was examined and was discussed in terms of plant behaviour.
