    Notes: Abstract It is shown that carrier degeneracy plays an important role in determining the electrical properties of double heterostructure injection lasers. Correct statistical treatment of the charge cariers in the device leads to a generalised Einstein relation between the carrier transport coefficients. Such a relation (for both electrons and holes) is used in numerical solutions of semiconductor transport equations applicable to the laser. Experimentally observed I–V characteristics of the laser are explained in terms of carrier degeneracy effects.

    Notes: Abstract In March 1991, large chlorotic patches appeared in an autumn-sown barley crop growing near Thessaloniki, Greece. Leaves had characteristic mosaic symptoms and immunosorbent electron microscopy and enzyme-linked immunosorbent assay confirmed the presence of both soil-borne mosaic viruses of barley, barley mild mosaic and barley yellow mosaic bymoviruses. In the following year, similar symptoms appeared in a crop at Souroti, 30 km east of Thessaloniki but the disease has not been found in other areas of Macedonia. This report is the first record of these viruses from Greece and is the most southerly European record.
