    Notes: Summary The metastasis of malignant tumors from a primary site to near and distant secondary sites is probably the most important event in the pathogenesis of cancer and it accounts for most cancer deaths1. Whereas advances in the treatment of primary cancer have led to increased patient survival, metastatic cancers are still the most difficult group of diseases to treat successfully2. As organ-characteristic lectins play an important role in the organ manifestation of metastatic islets3,4, it might be possible (e.g. during surgical operations on malignant tumors) to block those organ-characteristic lectins with the appropriate receptor-bearing glycoconjugates in order to inhibit the metastatic spread. Recent experiments have demonstrated that neuraminidase treatment of tumor cells (mouse sarcoma-1) alters in vivo (Balb/c-mice) the organotropic distribution of metastases; instead of being found exclusively in the lung, they are found both in lung and liver. However, pre-injection and regular application of D-galactose — the same holds for arabinogalactan5,6,13 — prevents the settling of metastases in the liver but does not influence the metastatic process to the lung, whereas mannan — as a galactose-free control substance — does not alter the initial pattern of metastasis to lung and liver.

    Description / Table of Contents: Riassunto Si è studiato lo spettro del rumore di un gradiometro superconduttore a derivata secon da in un agglomerato urbano. I dati sono stati ottenuti dal gradiometro con tre accelerometri ortogonali e un magnetometro a flussometro elettronico triassiale attaccato al dewar. Questi dati sono stati analizzati usando tecniche di elaborazione dei segnali, soprattutto un cancellatore adattativo di rumori, per ridurre i rumori nei dati del gradiometro. I risultati mostrano qui che il rumore dell’esterno e/o il rumore del movimento del dewar possono essere ridotti di 40 dB in potenza di rumore. Si è anche mostrato che, nel caso di basso rapporto segnale-rumore (S/N∼1), può essere estratta un’onda sunusoidale di 10 Hz. Questa tecnica non solo promette riduzione dei rumori, ma ha anche lo scopo d’identificare i segnali di rumore che potrebbero essere veramente considerati parte del responso evocato. L’analisi dei dati che contengono i responsi evocati è ora in corso.
    Notes: Summary The noise spectrum of a superconducting second-derivative gradiometer has been investigated in an urban environment. Data have been acquired from the gradiometer with three orthogonal accelerometers and a triaxial fluxgate magnetometer attached to the dewar. These data have been analyzed by using signal processing techniques, primarily an adaptive noise canceller, to reduce noise in the gradiometer data. Results shown here indicate that the environmental noise and/or the dewar motion noise can be reduced as much as 40 dB in noise power. It is also shown, in the case of poor signal-to-noise ratio (S/N∼1), that a 10 Hz sine wave can be extracted. This technique not only shows promise for noise reduction, but also aids in the identification of noise signals which might be misconstrued as part of the evoked response. Analysis of data containing evoked response is now underway.

    Notes: [Auszug] Since the phenomenon may be caused by either scintillations (of ionospheric or tropospheric origin) or by true variations in intensity of the source, or both, the term 'fluctuation' will be used to describe the effect, whatever its cause. The first fluctuation record of the object was obtained on ...

    Notes: [Auszug] FROM observations during the spring of 1954 with the Ohio State University radio telescope, a detailed radio map of the sky has been made. This map (Fig. 1) has sufficient detail to suggest how the sky would appear if our eyes were sensitive to radio waves instead of light. The central region of ...

    Notes: [Auszug] The antenna of the Ohio State telescope has a half-power beam width of 1-3 in right ascension and of 8 in declination. The right ascension of a source is determined by the time at which the maximum intensity is received, while the declination is determined by comparing records taken at several ...

    Notes: [Auszug] An interesting feature of the extended source (shown by the dashed line) is that it corresponds approximately in position to the plane of our local supergalaxy described by de Vaucouleurs3, and shown approximately in the figure by the dash-dot curve. The half-power width of the source is about 15 ...
