    Notes: Summary The effects of regularly eating sucrose were studied in 23 diabetic patients, 12 Type 1 (insulin-dependent) and 11 Type 2 (non-insulin-dependent), with differing degrees of glycaemic control. Two diets, each lasting 6 weeks, were compared in a randomised cross-over study. Both diets were high in fibre and low in fat. In one diet 45 g of complex carbohydrate was replaced by 45 g of sucrose taken at mealtimes. There were no significant biochemical differences between the two diets in either Type 1 or Type 2 patients. In Type 1 patients the mean (±SEM) fasting plasma glucose was 10.5 (1.8) mmol/1 on the control diet and 10.3 (1.5) mmol/1 on sucrose. In Type 2 patients the levels were 9.1 (0.8) mmol/1 and 8.9 (0.8) mmol/l respectively. Glycosylated haemoglobin for the Type 1 patients was 9.9% on control and 10.3% on sucrose; for Type 2 patients the figures were 9.3% and 9.0% respectively. There were no differences in mean daily plasma glucose levels or diurnal glucose profiles. Cholesterol (total and in lipoprotein fractions) was unchanged, as were diurnal triglyceride profiles and plasma insulin profiles in the Type 2 patients. There were no changes in medication or body weight. We conclude that a moderate amount of sucrose taken daily at mealtimes does not cause deterioration in metabolic control in diabetic patients following a high fibre/low fat diet.

    On sensitivity in optimal control problems (1974)

    Notes: Abstract Two types of interpretations of multipliers in both static and dynamic optimization problems are described. It is snown that the Lagrange multipliers encountered in mathematical programming problems and the auxiliary functions arising in Pontryagintype optimal control problems sometimes have highly analogous interpretations as rates of change of the optimal attainable value of an objective function, or in some cases as bounds on average rates of change.

    Fracture of long bones: Rate effects under singular and combined loading states (1983)
    Hoboken, NJ [u.a.] : Wiley-Blackwell
    Journal of Orthopaedic Research 1 (1983), S. 244-250 
    Details
    ISSN: 0736-0266
    Keywords: Fracture behavior ; Axial-torsional loading ; Life and Medical Sciences

    Topics: Medicine
    Notes: This study was undertaken to determine the effect of loading rate on bone failure under singular and combined loading states. Using the entire loading range of an Instron Materials Testing Machine, 190 pairs of canine radii were tested. One bone of each pair was subjected to either torsional or a combination of axial and torsional loads, and compared with a control specimen. Compressive loads of 4.6 and 11.5 N were utilized. Torque to failure and energy data versus loading rate were plotted. As loading rate increased, the torque and energy values were found to increase, reach a peak, and then decline at higher rates. Fractures produced under the combined state of loading are representative of those clinically found in human trauma situations.
