    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

The properties of the complex of calcium phosphate and caseinate were studied by both analytical and synthetic methods. The first approach, based on a great number of analyses of milk from individual cows, demonstrated that the composition of the complex (ratio of the various components) was widely variable, and that also Mg, Na, K and citrate were part of it. Also the cationbinding capacity of casein was studied and found to depend on several factors. By simultaneous titration at constant pH of calcium hydroxide and phosphoric acid, a complex phosphate was precipitated (relation Ca/P about 1.4), which is neither an orthophosphate, nor a hydroxy-apatite. If this titration was in caseinate solutions, a 'complex' could be synthetized. Its properties were in most respects according to those of the complex of milk. Although no definite answer could be given to the problem of the kind of bond between caseinate and phosphate, some existing hypotheses could be ruled out. The complex phosphate has distinct ion-exchange properties.
