    The development of the wheat embryo in relation to the neighbouring tissues (1983)

    Notizen: Summary The overall morphology of the developing wheat embryo in relation to its neighbouring tissues is described. The embryo is “isolated” early in development, but appears to be a powerful sink for nutrients. It is supplied initially by hydrolysis of the nucellar parenchyma and later by hydrolysis of neighbouring endosperm cells, which are completely digested. Later on, the nucellar epidermis forms specialised cells that may be transfer cells opposite the groove at the base of the embryo. The accumulation of starch and protein appears to begin first in the basal tissues of the scutellum and coleorhiza.

    Far infrared response of thin film Bi2Sr2CaCu2O8 using a free electron laser (1992)
    Springer
    International journal of infrared and millimeter waves 13 (1992), S. 1659-1666 
    Details
    ISSN: 1572-9559

    Thema: Physik
    Notizen: Abstract The far infrared response of granular thin-film Bi2Sr2CaCu2O8 superconductor has been investigated using long (≈5 μs) but sharply truncated free electron laser pulses in the frequency range between 50 cm−1 and 125 cm−1. Under constant current bias, a fast response and a slow bolometric signal component could be identified in this energy range, which is below the BCS energy gap (≈ 200 cm−1). Measurements of the power dependences of the signal voltages showed that both the fast and the thermal responses are consistent with the predictions of the resistively shunted Josephson junction model.
