    Analysis of deformation of nozzleless rocket propellent (1990)
    Springer
    Acta mechanica solida Sinica 3 (1990), S. 193-200 
    Details
    ISSN: 0894-9166
    Keywords: viscoelastic large deformation ; finite element program ; nozzleless ; rocket propellent Lagrangian approach
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: Abstract Based on the Total Lagrangian approach and the integral constitutive relation, the viscoelastic large deformation incremental variational equation is derived, and the finite element program of axisymmetric problems is written. By using this program the bore change of propellent of nozzleless rocket under the action of both the internal pressure and burning is dealt with in detail.

    NMR visibility of 35Cl- in human erythrocytes (1995)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 33 (1995), S. 66-69 
    Details
    ISSN: 0749-1581
    Keywords: NMR ; 35C1 NMR ; Erythrocytes ; Visibility of Quadrupolar Nuclei ; Relaxation ; Chemistry ; Analytical Chemistry and Spectroscopy

    Topics: Chemistry and Pharmacology
    Notes: Contrary to previous reports, Cl- is visible by 35Cl NMR inside human erythrocytes. In spectra run at 49.01 MHz the intracellular chloride has a linewidth at half-height of ca 700 Hz and shows double Lorentzian character. Mn2+ was used to relax the extracellular 35Cl- to allow the intracellular 35Cl- to be seen. The experimental protocol described should allow NMR observation of anion transport rates in human erythrocytes.
