An extension of Wetzel* s theory is proposed to explain electron precursor phenomena in pressure driven shock tubes. The theory is based on the assumption, which hae been experimentally verified, that radiation from the hot gas behind the shock front is responsible for the precursor effect. A point radiator, located at the shock front and moving with the shock velocity, is assumed. It is shown ...

The processing and analysis of the Mizar library has been performed using the infrastructure of the University of Bialystok High Performance Computing Center. In the current Mizar language, direct linking to statements formulated as compound conditions is prohibited. This particular language feature has often been considered by the users as an unnecessary disruption of the natural course of pro...

Following several recent approaches, working memory is argued to consist of a subset of representations that are within the scope of active processing and a larger set of recently activated, but non-attended representations. A response-signal speed-accuracy tradeoff (SAT) and complementary reaction time variant of a probe recognition task were used to measure the retrieval of categorized materi...

At 24 hours after administration of a single dose of 3-4 mg. of l-hydroxy-2-acetylaminofluorene-1-C14 (1-hydroxy-AAF-l-C14) intraperitoneally to rats, 75 per cent of the dose had been excreted in the urine and feces. About 5 per cent of the injected radioactivity was present in the gastrointestinal contents, and only 1-2 per cent re mained in the tissues of the rat. Radioactivity equivalent to ...
