In this paper, we report the first successful fabrication of dense and optically transparent cadmium tungstate (CWO) films by sol-gel processing and the study of their optical and x-ray scintillation properties. A new sol-gel processing method was developed using tungstic acid and cadmium nitrate as precursors and hydrogen peroxide as solvent; homogeneous and stable CWO sols were aged at room t...

Hedqvist, H. 2004. Metabolism of soluble proteins by rumen microorganism and the influence of condensed tannins on nitrogen solubility and degradation. Doctoral thesis. ISSN 1401-6249, ISBN 91-576-6780-2. The amino acid requirements of ruminants are met by two sources; microbes leaving the rumen and dietary protein escaping fermentation in the rumen. Much ruminant research has therefore focused...

In this procedure for serum amylase the sugars formed by enzymatic starch hydrolysis are quantitatively measured in a protein-free tungstic acid filtrate by the alkaline reduction of ferricyanide to ferrocyanide. The ferrocyanide formed is readily determined by measurement of the color produced with phosphomolybdic acid at room temperature. The reducing sugar formed, expressed as milligrams per...

THE work to be described was undertaken with the intention of investigating the optically active substances of blood other than glucose. It was stated by Winter and Smith [1922] that the optical rotation of a concentrated protein-free filtrate of mammalian blood was initially less than that calculated from the amount of glucose estimated to be present. This difference they attributed to the pre...
