Type extension is a language facility proposed by N. Wirth and included in the programming language Oberon. The facility allows a type to be created based on another type while maintaining a hierarchic type relationship. This paper gives an introduction to the type extension facility as it is implemented in Oberon and shows how it can be general ised to allow a non-l inear type hierarchy to be ...

This article presents data on health care spending for the United States, covering expenditures for various types of medical services and products and their sources of funding from 1960 to 1994. Although these statistics for 1994 show the slowest growth in more than three decades, health spending continued to grow faster than the overall economy. The Federal Government continued to fund an incr...

heavy water plus neutral current additive to an activity level of one decay per day per tonne ofD^O (DDT) for the thorium chain and(5(TpDTs for the uranium chain. /O jL^ It is equally important to be able to monitor these activity levels, by some form of ^f radioactive assay. From the point of view of purification the critical isotopes are 2 y year ^Th in the thorium chain (see Fig. 1) and 1600...

We describe a case of blastomycosis in an 8-year-old boy with Blastomyces-associated osteomyelitis and possible pulmonary involvement. We also identify 309 cases of blastomycosis in Ontario that were seen during a 10-year period, 57% of which occurred from 2001 to 2003. The overall incidence during the study period was 0.30 cases per 100,000 population. Most patients were from north Ontario (n ...

My interest in this area started at the “Center for Global and Regional Environmental Research” (CGRER) of the University of Iowa. There I worked in an interdisciplinary team together with Gregory Carmichael from the Chemical Engineering Department and several Ph.D. students in chemical engineering, computer science, and applied mathematics. The goal of that group was to develop a “Third Genera...
