This article is a critical review of some of the methods that have been used for the sampling, analysis, and monitoring of vapor-phase toluene diisocyanate (TDI). Only some of the methods that have received relatively widespread application have been addressed in this article. This review includes a "tutorial style" discussion of basic definitions and basic principles and procedures of quality ...

While Markov chain generators have been employed throughout the history of computer music as a tool for the creation of musical parameter values, input notations for Markov transition values are often cumbersome and opaque. Rejecting the transition matrix as an input notation, this paper offers a new language-independent, string-based input notation for incomplete, multiple-order, static Markov...

Assessment of exposure to airborne endotoxins has been studied for several years, especially in occupational environments, but a large number of procedures are used for sampling and analysis. This lack of standardization makes it very difficult to compare results and set internationally accepted threshold limit values (TLVs) or occupational exposure limits (OELs) for endotoxin exposure. This pa...
