abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...

Today, Productivity is an all-encompassing and comprehensive issue. It does not only include a library but the whole society. It mostly deals with the materialization of objectives, use of resources for positive produ:ction, and finally the comparison between that, which is attained and that, which is feasible. Based on the said definitions, a case study was made on the finished cost of the boo...

we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...

Although the approach that has been aimed at social capital has led to achievements in the Social Sciences domain, but again, it has also brought about cases of confusions. Some of these confusions are related to the comparison of the social capital extent at an international level. Most of the researchers believe that there are differences in the social capital indicators of the different soci...
