Pure grammars and pure languages†

International Journal of Computer Mathematics, 1981
The notion of “pure grammar” is introduced as a semi-Thue system with no non-terminals. The basic properties of pure grammars and the “pure languages” that they generate are investigated. Other topics introduced are “definite Turing machines” that accept pure languages, pure parallel languages, pure relations and pure Post canonical systems.

PURE LAPAROSCOPIC ENTEROCYSTOPLASTY

The Journal of Urology, 2002
The realm of laparoscopic surgery has expanded from simple extirpative operations to more complicated reconstructive procedures, such as dismembered pyeloplasty and ileal conduit creation. There has been recent interest in using laparoscopic techniques to augment the bladder with bowel.1, 2 To date only 1 case of enterocystoplasty, using the stomach ...

Pure Subfields of Purely Inseparable Field Extensions

Canadian Journal of Mathematics, 1976
The notion of pure subgroups is due to Prufer [7]. It has proven extremely useful in establishing structural properties of abelian groups. In a recent paper [9], Waterhouse introduced the concept of a pure subfield of a purely inseparable extension. Let L be a purely inseparable modular extension of k, and let K be an intermediate field.
