✦ Synopsis

The performance of the normalization method (NM) is evaluated and compared with the standard unloading-compliance method of fracture-toughness analysis for a broad spectrum of different materials and specimen geometries. The critical J-integral values based on the normalization method are summarized and compared with the results of unloading compliance tests. The results demonstrate the applicability of the normalization method for the J-R curve determination for a range of steels. The normalization method yields results, which deviate as much as 15% from the values obtained with the unloading compliance method, and thus results of acceptable accuracy can be attained with this method.

## Abstract The normal‐acid method for the estimation of fibre in roughages by single acid digestion has been re‐examined. Increasing the time of digestion from 1 to 3 h. gives a marked improvement in the correlation with digestibility. Changes in technique are also introduced which make the method

A computerized and precise method for the determination ofthe osmotic fragility curve of erythrocytes was developed. The pH and the temperature, the most important factors for the osmotic hemolysis, were controlled with an accuracy of 7.40 ? 0.01 and 25.0 ? 0.2"C, respectively. The method required a
