BACKGROUND Although the Netherlands currently has its own procedure for evaluating chemical compounds and setting occupational exposure limits (OELs), most of these limits were originally adopted in the 1970s from threshold limit values (TLVs) set by the American Conference of Governmental Industrial Hygienists (ACGIH). However, beginning in the late 1980s, criticism about non-scientific consid...

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 ...

Modern wheat breeding programs aim to create cultivars with high genetic potential for yield and bread-making quality. Th e eff ectiveness of selection in segregating generations depends on the heritability of the traits under selection and on the correlations among traits. Th e aim of this study was to compare realized heritability of 1000 kernel weight and fi ve indirect bread-making 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 this study, the physical (color, grain size, equivalent diameter, sphericity, kernel surface area, volume, thousand weight, hectoliter dry weight and wet weight), physicochemical (technological) (dry water absorption capacity, index, swelling gluten Zeleny sedimentation delayed sedimentation) chemical (moisture, protein contents) properties of most grown bread wheat varieties (Triticum aesti...

Developing countries have embarked on the promotion of “ICT access for all” through subsidized Information and Communication Technologies (ICTs), especially in underserviced areas of such countries. The main aim of the “ICT access for all” is to extend the communication services to the large areas of underserviced regions through subsidized communication services. In some instances, subsidies m...
