    Notes: [Auszug] We have been interested in exploring further the relationship between schizophrenia and the urinary excretion of 3,4-dimethoxyphenylethylamine, both because it seems probable that metabolic errors underlie some forms of psychosis, and because this particular amine is known to have a marked effect ...

    Notes: [Auszug] We have been unable to detect any DMPE in the urines of either acute11 or chronic schizophrenics who had been given a potent monoamiiie oxidase inhibitor12. We have found, however, that schizophrenic patients, and other psychotic or mentally defective patients in mental hospitals, and even mentally ...

    Notes: [Auszug] WHILE investigating an unusual disease involving disordered methionine metabolism which is to be reported elsewhere1, we encountered an unidentified amino-acid on paper chromatograms of urine. Urine from an infant who exhibited marked methioninaemia and methioninuria was subjected to ...

    Notes: Abstract By tracing the positions of filaments on the solar disk for a series of consecutive Carrington rotations, one can make a compact representation of the changes in general topology of photospheric magnetic fields during the course of a solar cycle. Examples are shown for the time period 1964–1974, which may provide some insight into the long-term relationship of the mid-latitude diagonal filaments and the high latitude polar crown.

    Notes: Abstract A process is suggested by which a coronal structure (with underlying filament) may form between a polar crown structure and a low-latitude bipolar region. During the ascending phase of the solar cycle the identifying underlying filament should lie poleward and westward of the active region, but during the descending phase it should appear as an eastward extension of the filament separating leader and follower photospheric fields within the active region.

    Notes: Abstract A systematic investigation was made of the K-corona immediately overlying the positions of the brightest and most isolated chromospheric plages during the years 1964–1967. In all cases, the corona was found to be enhanced with peak brightness proportional to the plage area. In the absence of plages, the K-coronal brightness remained at a quiet level which was essentially the same thoughout this part of the solar cycle.

    Notes: Abstract The principal polar-crown coronal helmet structures were selected from nearly three years (May, 1965–January, 1968) of K-coronameter observations made at Haleakala and Mauna Loa, Hawaii. Six isolated and long-lived helmet systems were found at latitudes of 45° and above. Their developments are compared with underlying chromospheric and photospheric activity and a simple phenomenological model is presented showing that a coronal system is formed over an active region. Thereafter the center of gravity of the system gradually drifts poleward with the trailing unipolar magnetic region (UMR), and it becomes a high latitude coronal helmet, arched over a polar crown filament. By comparison of these coronal helmets with observations of the outer corona (to circa 4 R ⊙) made at solar eclipse, lunar sunset, and with balloon and rocket-borne externally occulted corona-graphs, it appears that ground-based K-coronameter measurements to a distance of 1.5–2.0 R ⊙ are sufficient to detect the coronal streamers.

    Notes: Abstract Central-meridian passage of coronal equatorial arches is followed, statistically, after about 7 days by geomagnetic disturbance. Sector-boundary crossings at Earth are most likely to occur 5 days after arch CMP, while metric noise sources cluster at the location of the arches. This agrees with the location of the noise sources relative to sector boundaries described by Sakurai and Stone (1971), rather than with that found by Martres et al. (1970) for 1964 and 1966, and may indicate evolution of the relation between coronal and interplanetary structure. We looked for, but did not find, clustering of coronal arches at a particular phase of the Olsen rotation scheme.

    Notes: Abstract Because of the progressive decrease in rotation rate of the solar plasma at increasing latitudes, the photospheric foot-points of large-scale closed magnetic structures in the corona, which are originally widely separated in longitude, may ultimately be brought into proximity. Magnetic mergers and reconnections between magnetic fields of opposite polarity are presumed to occur, producing major structural changes in the corona and in the locations of underlying filaments. Thus we believe that the differential rotation phenomenon is essential to understanding both gradual (evolutionary) and sudden (transient) changes in the corona, and that they can occur without any observable change in the photospheric magnetic flux. A process is suggested for the splitting or bifurcation of a high-latitude magnetic structure, producing two separate components at the same latitude, whose rotation rates are influenced by their respective magnetic linkages to other regions on the Sun.
