    Notes: [Auszug] In 1977, Stephen Weinberg observed that “the theory of the formation of galaxies is one of the great outstanding problems of astrophysics, a problem that today seems far from solution”. Although the past two decades have seen considerable progress, many questions remain. Broadly ...

    The Senate after Sulla (1962)

    Notes: We have most of us been surprised when, after reading the history of the late Republic, we first discovered that in the year 50 a motion was proposed in the Senate that Pompey and Caesar should both lay down their commands, that it was passed by 370 votes to 22, and that it was disregarded in the interests of the optimate leaders. Who were these 370 men, and why do we not hear more of them? We have read, of course, that the Senate consisted of this or that number at this or that time; and then we read all about the Claudii and Metelli, with scarcely a word about the massed ranks behind them. Yet there they are, and the picture is incomplete without them. It is likely that we shall never complete it satisfactorily—there are so many of them we do not know, and the few we do know are quite likely to be exceptional in some way—but we can at least make a start by considering the numbers involved and the likely divergence as well as the unity of their interests.

    The Ringberg Standards for NGC 1068 (1997)
    Springer
    Astrophysics and space science 248 (1997), S. 9-19 
    Details
    ISSN: 1572-946X

    Notes: Abstract At the end of three days' spirited discussion of the type 2 Seyfert galaxy NGC 1068, what do we think we understand about this object? New observations -- particularly in the infrared and radio -- are helping to resolve old problems, while drawing attention to new ones. It appears that NGC 1068 is a relatively normal spiral galaxy in which large-scale gravitational disturbances are funneling matter into the nucleus. A collimated outflow disturbs the interstellar medium out to kiloparsec scales, but the nucleus itself is hidden behind an opaque screen. Radio observations have now pierced the screen, and suggest that at the center of it all, a 10-20 million solar mass black hole is accreting at close to its Eddington limit.

    Strict Limits on the Ionizing Luminosity in NGC 1068 from Jet-Axis Molecular Clouds (1997)
    Springer
    Astrophysics and space science 248 (1997), S. 177-190 
    Details
    ISSN: 1572-946X

    Notes: Abstract The radio jet axis of NGC 1068 is characterised by energetic activity from x-ray to radio wavelengths. Detailed kinematic and polarization studies have shown that this activity is confined to bipolar cones centered on the AGN which intersect the plane of the disk. Thus, molecular clouds at 1 kpc distance along this axis are an important probe of the nuclear ionizing luminosity and spectrum. Extended 10.8µm emission coincident with the clouds is reasonably understood by dust heated to high temperatures by the nuclear radiation field. This model predicts that the nuclear spectrum is quasar-like (power law + blue excess) with a luminosity 2-5 times higher than inferred by Pier et al. (1994). Consequently, there is little or no polyaromatic hydrocarbon (PAH) emission associated with the radio-axis molecular clouds. We review this model in the light of new observations. A multi-waveband collage is included to illustrate the possible orientations of the double cones to our line of sight and the galaxian plane.

    Notes: [Auszug] One complete antler was ashed, a strontium separation carried out with added carrier and the activity measured on a Geiger-M ller counter. The activity (strontium-89 plus strontium-90, and possibly active traces of other alkaline earths and heavy metals) was found to be 126 µµc../gm. of ...

    Immunohistochemical localization of oxytocin and vasopressin in the adrenal glands of rat, cow, hamster and guinea pig (1987)
    Springer
    Cell & tissue research 250 (1987), S. 1-6

    Notes: Summary The distribution of oxytocin and vasopressin in the adrenals of rat, cow, hamster and guinea pig has been studied by use of immunohistochemical techniques. In all the species studied the adrenal cortex contained both peptides; the staining in the zona glomerulosa being more intense than that in zona fasciculata or zona reticularis. The medulla, however, showed considerable species variation. In the cow, both peptides appear to be present in the adrenergic and noradrenergic cells, though staining was particularly prominent in cortical islands interspersed within the medullary tissue. In the rat, groups of medullary cells positive for both peptides were found, though it was not possible to associate these groups with particular chromaffin cell types. In the hamster oxytocin was present only in adrenaline-containing cells, whereas vasopressin was present in all medullary cells. The guinea pig medulla, which contains only adrenaline-secreting cells, was positive for both peptides. The possibilities that vasopressin and oxytocin have an autocrine or paracrine role in functioning of the adrenal gland is discussed.
