A Stone-Weierstraß type theorem for semiuniform convergence spaces is proved. It implies the classical Stone-Weierstraß theorem as well as a Stone-Weierstraß type theorem for filter spaces due to Bentley, Hušek and Lowen-Colebunders [1].

The effects of a new transfusion filter (Bentley PFF-100) on stored whole blood have been examined. Six filters were preloaded by passage of two units of outdated type-specific bank blood and the effects of filtration on a third unit of 21-day-old blood flowing under 19.95 kPa (150 mm Hg) pressure were measured. Filtration did not significantly alter erythrocyte or leukocyte count, total or pla...

Are there empirical anomalies upon which Dewey’s theory of action sheds better light than existing neoclassical and heterodox approaches? The introduction answers in the affirmative. They are the set of anomalies highlighted by behavioral economics. These anomalies stress the centrality of context. Neoclassical theorists react to the ‘context problematic’ by claiming that context, after all, is...

Normal Form In order to fit any grammar into the conditions required by the previously described matching techniques, we demand the following normalisation: 1. lack of labels for production rules 2. lack of named subexpressions 3. lack of terminal symbols 4. maximal outward factoring of inner choices 5. lack of horizontal production rules 6. lack of separator lists 7. lack of trivially defined ...

We present the case of a 64-year-old man who was referred to our service after sustaining a self-inflicted nail-gun injury to his chest. He received three nails penetrated into his chest. Computer tomography revealed no massive haemorrhage or damage to major vessels. He underwent an emergency sternotomy, two nails caused pericardial perforation and myocardial injury were noted easily and remove...
