The finite Fourier transform is discussed from the viewpoint of finite dimensional algebras over commutative rings. Three main consequences of this approach are developed. First we assunle G to be an arbitrary finite Abelian group of order n and R to be a commutative integral domain. I t is shown that the group algebra R[G'] is isomorphic to the "pointwise(More)
Solutions A and B (15.8% ferrous sulfate in 0.3% citric acid and 6% sodium carbonate, respectively) have been available as a first-aid treatment for cyanide ingestion for many decades. Controversy surrounding the efficacy of solutions A and B has existed for much of that time, the main protagonists being in the UK. The current opinion in the UK is that(More)
BACKGROUND AND AIM OF THE STUDY The present authors' experience with mitral valve reconstruction was reviewed to determine the influence of anatomical and functional abnormalities on mortality and reoperation. METHODS Between 1991 and 2001, a total of 397 patients (mean age 59.0 +/- 13.4 years) underwent mitral valve reconstruction at the authors'(More)
3 C anada’s economy turned a corner in the 1990s. What happened? Most Canadians would give a lot of credit to the dramatic about face on the deficit in middecade. We finally began to live within our means; made room for taxes to be cut; and came to rely less on bureaucrats and more on entrepreneurs. Those who follow these issues more closely would also(More)
This report describes a case of phobic anxiety relating to cyanide in a process operator who is unable to smell hydrogen cyanide. This case demonstrates that hazardous substances in the workplace can provoke this mental disorder in individuals who are unable to detect by special senses whether or not a specific hazard is present. The clinical management of(More)
