An examination of the cyanide derivative of bovine superoxide dismutase with electron-nuclear double resonance
(Elsevier, 1982-05-21)
The Cu(II) sites of native, azido- and cyano-derivatives of bovine superoxide dismutase (superoxide:superoxide oxidoreductase, EC 1.15.1.1) have been examined by electron-nuclear double resonance ENDOR). The ENDOR spectrum ...
Effects of material properties and crush conditions on the crush energy absorption of fiber composite rods
(Elsevier, 1993)
Crushing along the fiber axis of undirectional E-glass fiber composites rods was examined to determine the effects of fiber volume fraction, fiber diameter, matrix compressive yield strength, crush rate, fiber surface ...
Percolative versus homogenous energy transport kinetics: time-resolved donor and acceptor fluoresence of isotopic mixed naphthalene crystals
(Elsevier, 1982-04-16)
Tune-resolved spectral studies of the singlet exciton transport threshold in doped naphthalene-perdeuteronaphthalene mixed crystals are presented. While a homogeneous kinetic model adequately explains many of the results, ...
2-Substituted methyl [alpha]--galactopyranosides: Synthesis and binding affinity for the A and B subunits of the Griffonia simplicifolia I isolectins
(Elsevier, 1985-07-01)
The binding affinities of the N-acetyl, N-trifluoroacetyl, N-propionyl, N-formyl, N-benzoyl, N-p-nitrobenzoyl, N-p-aminobenzoyl, and N-methyl derivatives of methyl 2-amino-2-deoxy-[alpha]--galactopyranoside and the 2-O-acetyl, ...
The faradaic admittance of electrochemical processes : III. The frequency dependence
(Elsevier, 1961)
Recent experimental studies have demonstrated the inadequacy of proposed equations for the faradaic admittance, particularly in respect to the frequency dependence. Existing treatments of the faradaic admittance can give ...
Linearized embedding: A new metric matrix algorithm for calculating molecular conformations subject to geometric constraints
(John Wiley & Sons, Inc., 1989-10)
There are many methods in the literature for calculating conformations of a molecule subject to geometric constraints, such as those derived from two-dimensional NMR experiments. One of the most general ones is the EMBED ...
Vibrational analysis of crystalline diketopiperazine--II. Normal mode calculations
(Elsevier, 1984)
Based on our Raman and i.r. [1] data and assignments for DKP and five of its isotopic derivatives, we have refined an intramolecular force field in a non-redundant basis. This analysis shows that the cis peptide group may ...
Association of calmodulin inhibition, erythrocyte membrane stabilization and pharmacological effects of drugs
(Elsevier, 1982-11-08)
The present study was designed to determine whether there is an association of drug-induced inhibition of calmodulin functions, drug-induced membrane stabilization (protection against osmotic lysis), and pharmacological ...
Transtubular bioreactor: A perfusion device for mammalian cell cultivation
(Kluwer Academic Publishers; Science & Technology Letters ; Springer Science+Business Media, 1989-01)
A transtubular mammalian cell perfusion chamber has been developed that allows separate delivery and control of medium and gas flow to the cells. The hydrodynamic and mass transfer characteristics of the reactor are studied ...
