Using a function algebra characterization of exponential time due to Monien 5], in the style of Bellantoni-Cook 2], we characterize exponential time functions of linear growth via a safe course-of-values recursion scheme.

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 ...

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...

In order to understand the reasons for seeking a better means of incorporating "intangible" or "fragile" values into systems analysis, it is necessary to understand the functions analysis fulfills (or might fulfill) in environmental decisions-decisions that are fundamentally political in the sense that they ultimately involve competing or conflicting values, and therefore cannot be resolved by ...

urban growth and development caused many environmental problems in current age. one of these problems is environmental impacts of wastes which can be solved by inhabitant’s participation in municipal recycling and waste programs. there are many psycho-social factors affecting people’s participation in municipal waste and recycling programs. one of these factors is environmental values. so, curr...
