The results of pseudospark discharge observation with spatial and temporal resolution together with the measurements of EUV radiation are presented. It is shown that in a mode of superdense glow ...discharge the electron temperature in the discharge plasma is high enough to provide for generation of EUV radiation without magnetic compression of the plasma channel.
The paper describes the main features of the experimental installation for investigation of a high current pulsed gas discharge, which burns in typical conditions of EUV source operation.
The paper describes the regimes of energy input in the pseudospark discharge in typical conditions of EUV source operation. It is shown that in a mode of superdense glow discharge the electron ...temperature in the discharge plasma reaches rather high values without self-magnetic compression of the plasma channel.
The postmicrosomal protein fraction from rat hepatoma 27 adjusted to pH 5.1 stimulates phospholipid exchange between rat liver microsomes and mitochondria with higher rates and in a less specific way ...than the corresponding fraction from rat liver. A phospholipid exchange protein has been purified to homogeneity from the hepatoma pH‐5.1 supernatant by gel filtration on Sephadex G‐75 and ion‐exchange chromatography on carboxymethylcellulose. The isolated protein had a molecular weight of 11 200 as determined by electrophoresis on polyacrylamide in the presence of dodecyl sulfate and of 11 168 as calculated from the amino acid composition. Isoelectric focusing showed a single band at pH 5.2.
In the assay system rat liver microsomes → mitochondria the protein exhibits a complete lack of substrate specificity transferring all the major microsomal phospholipids to about the same extent. The possible role of the isolated phospholipid exchange protein in the chemical dedifferentiation of hepatoma cell membranes is discussed.
