    Summary Implantation of 2 pairs of cerebral glands of the diplopodJonespeltis into the newly-moulted 4th or 5th instar nymphs of the insectDysdercus delayed the moulting of these insects for a fairly long time. Implantation of cerebral glands into 1-day old 5th instars postponed the subsequent moult for a shorter period, whereas implantation of cerebral glands into 2-day old 5th instars had no effect. These observations suggested that a neurosecretory factor from the cerebral glands inhibited moulting in this insect, and in the case of 5th instar nymphs there was a critical period before which implanted glands were effective in moult inhibition.

    Notes:
    Zusammenfassung Unterbrechung eines Schlundkonnektivs oberhalb des Konnektivkörpers des DiplopodenJonespeltis spledidus führt auf der operierten Seite zur Akkumulation von neurosekretorischem Material in hirnnahen Axonen und zu einer Entleerung des Konnektivkörpers. Eine entsprechende Durchtrennung des Konnektivs unterhalb des Konnektivkörpers hat keinen Einfluss auf den Füllungszustand des letzteren, führt aber im unterhalb der Operationsstelle gelegenen Konnektiv zu einer gewissen Akkumulation von Neurosekreten. Das neurosekretorische Material wandert offenbar hauptsächlich vom Gehirn her, aber auch aus dem Unterschlundganglion zu den Konnektivkörpern, die als Neurohämalorgane zu dienen scheinen.

    Notes:
    Homoepitaxial Si films were deposited using an ArF excimer laser beam parallel to the substrate to photodissociate Si2H6 at low temperatures (250–350 °C) under laser intensity and Si2H6 partial pressure conditions that result in low initial photofragment concentrations (〈 1013 cm−3). Total pressure and flow conditions were chosen such that there is little secondary photolysis of the initial photofragments. The deposition yield of solid Si from photoexcited Si2H6 is estimated to be 0.20±0.04, indicating that in order for film growth to result solely from the primary products in ArF laser (193 nm) photolysis of Si2H6, a sticking coefficient ≥0.6 must be assigned to the dominant growth precursor. Growth rates vary linearly with laser intensity and Si2H6 partial pressure over a range of 1–15 mJ/cm2 pulse and 5–40 mTorr, respectively. Increasing the distance between the laser-beam axis and the silicon substrate results in a reduction of the growth rate that can be explained by gas-phase chemical reaction of the growth precursors as they diffuse to the substrate. Epitaxy is maintained for temperatures above the threshold for thermal decomposition of surface (SiH2)n chains at ∼250 °C, and for temperatures below the onset of Si2H6 pyrolysis and rapid thermal desorption of surface H2 at ∼350 °C.

    Notes:
    [Auszug] In 1990, the observation by J. Wolff et al.1 that naked plasmid DNA encoding marker genes could be expressed following intramuscular (i.m.) injection in mice initiated an enormous amount of activity related to direct in vivo gene transfer. In their initial study, Wolff et al. found that the in vivo ...
