    Notes: A technique for smoothing the transition between structural components modelled with dissimilar finite element meshes is presented. The interface mismatch is assigned a potential of dislocation, which is minimized with respect to selected kinematic parametes of the mating surface. This leads to linear constraints between the caididate representations of the mating surface which essentially dictate a least-square error in dislocaiton. The constraints are enforced by the Lagrange multiplier or reduced stiffness technique. Numerical results indicate gradual transition in the predicted stresses neighbouring the interface. Existing computer codes which permit multipoint constraint specifications are readily available to implement the technique.

    Notes: Finite element models for linear elastic plane stress problems which provide, alternatively, a completely compatible displacement field or a precisely equilibrated stress field are developed. The basis for both models is a biquintic interpolation polynomial representing Airy's stress function over a triangular region. The polynomial coefficients are modified and grouped to establish compatibility while retaining equilibrium within each element. Nodal kinematic parameters are selected and matched to the stress function for the compatible (modified stiffness) model, while nodal stress function parameters are chosen for the equilibrium (modified flexibility) model. Constraints on the global freedoms, enforced by Lagrange multipliers, are introduced to augment nodal connectivity in establishing interelement compatibility in the ‘stiffness’ model and uniform stress transmission in the ‘flexibility’ model. Appropriate boundary conditions are formed for each model. Numerical solutions are obtained and assessed.

    Glucose metabolism of mammalian erythrocytesSupported in part by a Public Health Training Grant (GM-633) from the National Institute of General Medical Sciences. (1976)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Under physiological conditions, erythrocytes of the horse metabolized 638 ± 37 (± SE) nmoles glucose/ml cells/hr at 37°C compared to 942 ± 31 for the cat, 1,329 ± 44 for the dog, and 1,485 ± 43 for man. On an absolute basis, pentose phosphate metabolism was similar between species, with species differences in erythrocyte glucose utilization attributable to differences in Embden-Meyerhof pathway metabolism. By examining pentose phosphate pathway recycling, it appears that some functional compartmentation exists within erythrocytes.
