    Determination of biologically available phosphorus using a radiobioassay technique (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Freshwater biology 15 (1985), S. 0 
    Details
    ISSN: 1365-2427
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SUMMARY. 〈list xml:id="l1" style="custom"〉1A kinetic approach in which the uptake rate of simultaneous additions of orthophosphate and carrier-free phosphorus- 32 by a standard culture of the green alga Selenastrum capricornutum under near neutral conditions was used to obtain an estimate of the readily available components of the total phosphorus pool in natural freshwater samples.2A comparison was made between the values of the biologically available phosphorus obtained using this radiobioassay technique and those obtained by the soluble reactive phosphorus procedure for thirty-one freshwater samples. Only about three-quarters of the phosphorus measured as soluble reactive phosphorus was readily available to algae. The results agreed with those obtained in an earlier study in which an enzymatic procedure was used to determine orthophosphate.3The results of tests carried out on the water samples used in this study were consistent with the conclusion that the presence of a hydrous ferric oxide-orthophosphale complex in the samples caused the soluble reactive phosphorus value to be greater than the corresponding biologically available phosphorus value.

    Multiwavelength analysis of a well observed flare from SMM (1985)
    Springer
    Solar physics 99 (1985), S. 167-188 
    Details
    ISSN: 1573-093X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We describe and analyse observations of an M1.4 flare which began at 17: 00 UT on 12 November, 1980. Ground based Hα and magnetogram data have been combined with EUV, soft and hard X-ray observations made with instruments on-board the Solar Maximum Mission (SMM) satellite. The preflare phase was marked by a gradual brightening of the flare site in Ov and the disappearance of an Hα filament. Filament ejecta were seen in Ov moving southward at a speed of about 60 km s−1, before the impulsive phase. The flare loop footpoints brightened in Hα and the Caxix resonance line broadened dramatically 2 min before the impulsive phase. Non-thermal hard X-ray emission was detected from the loop footpoints during the impulsive phase while during the same period blue-shifts corresponding to upflows of 200–250 km s−1 were seen in Ca xix. Evidence was found for energy deposition in both the chromosphere and corona at a number of stages during the flare. We consider two widely studied mechanisms for the production of the high temperature soft X-ray flare plasma in the corona, i.e. chromospheric evaporation, and a model in which the heating and transfer of material occurs between flux tubes during reconnection.

    Identification of [Fe III ] in the solar ultraviolet spectrum (1986)
    [s.l.] : Nature Publishing Group

    Notes: [Auszug] The wavelengths of the emission lines are given in Table 1. Three groups of lines occur, the strongest between 1,575 and 1,598 A, the others between 1,503 and 1,518 A and between 1,431 and 1,452 A. The wavelengths were determined on a scale established from nearby lines of neutral atoms. For the ...

    Notes: [Auszug] THERE are few spectral ranges in which observations of astrophysical sources have not been made. One of the few is the extreme ultraviolet region, which is virtually unexplored owing to earlier assumptions that the interstellar medium would be opaque at wavelengths between the hydrogen Lyman ...

    Karyotypic study of titi monkeys,Callicebus moloch brunneus (1989)
    Springer
    Primates 30 (1989), S. 81-88 
    Details
    ISSN: 0032-8332
    Keywords: Callicebus moloch brunneus ; New World monkey ; Karyotype ; Comparative cytogenetics ; Differentiation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract A karyotypic study on a subspecies of the dusky titi,Callicebus moloch brunneus, was carried out and a third karyotype ofC. moloch was discovered. The chromosome number of this subspecies is 48. The autosomes consist of 5 subtelocentric, 5 submeta- or metacentric, and 13 acrocentric chromosome pairs. The X chromosome and the Y chromosome are submetacentric and metacentric, respectively. A comparative study with other subspecies of theC. moloch group (i.e.,C. m. cupreus andC. m. ornatus with 2n=46 andC. m. donacophilus with 2n=50) suggests that the karyotype ofbrunneus occupies a position intermediate between the two other karyotypes ofC. moloch, but nearer to that of 2n=50. The presumed total differences betweenbrunneus andcupreus comprise one Robertsonian rearrangement, one centromeric transposition and four pericentric inversions, and those betweenbrunneus anddonacophilus involve one translocation or breakage (possibly corresponding to two events, that is, one Robertsonian rearrangement and one centromeric transposition).

    Monoterpenoid content of sage grouse ingesta (1989)
    Springer
    Journal of chemical ecology 15 (1989), S. 961-969 
    Details
    ISSN: 1573-1561
    Keywords: volatile oils ; essential oils ; digestion ; Centrocerus urophasianus ; big sagebrush ; Artemisia tridentata ; sage grouse
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract We tested the hypothesis that the monoterpenoid levels in the ingesta from various digestive organs of sage grouse are less than that expected from the big sagebrush leaves ingested. Results supported the hypothesis. Dramatic reductions occurred between the gizzard and duodenum. Monoterpenoid levels in the ceca were nil; thus adverse effects of monoterpenoids on ceca microbes would also be nil.
