A 1,10-hofmann elimination. Synthesis of a [6.6]paracyclopane tetraene
(Elsevier, 1983)
The synthesis of (, , , ) - [6.6]paracyclophane-1,5,13,17-tetraene the [10+10] cyclodimerization of 7,8-divinyl-p-quinodimethane is described.
The cohydrolases in human spleen that stimulate glucosyl ceramide [beta]-glucosidase
(Elsevier, 1983-10-17)
A family of [beta]-glucosidase-stimulating proteins (called cohydrolase SPH-I here) was isolated from bovine, Gaucher human and control human spleens. All preparations exhibited a similar pattern of four major electrophoretic ...
Turbidimetric determination of particle size distributions of colloidal systems
(Elsevier, 1983-03)
Application of the Mie theory of light scattering to measurements of the turbidity ratio and the wavelength exponent provides an easy method for estimating particle size distributions of nonabsorbing isotropic spheres in ...
Thermophysics of metal alkanoates I. Heat capacities and thermodynamic properties of sodium methanoate and ethanoate
(Elsevier, 1983-05)
The heat capacities of two sodium alkanoates have been studied by adiabatic calorimetry. Earlier measurements from this laboratory on sodium methanoate between 5 and 350 K are supplemented from 300 K to melting. Sodium ...
Partial closure of cracks at the interface between a layer and a half space
(Elsevier, 1983)
The paper treats the crack at the interface between a layer and a substrate. Using a formulation based on dislocations, the problem is reduced to a pair of singular integral equations which can be solved numerically. It ...
Acceptor activity, isoacceptor profiles and function in protein synthesis of transfer RNAs from regenerating skeletal muscle
(Elsevier, 1983-12-22)
Transfer RNAs have been prepared from control and regenerating rat skeletal muscle. The yield of tRNA is highest during the early stages of the regeneration process (5 and 8 days following the induction of regeneration) ...
Impact properties of steel fibre reinforced concrete in bending
(Elsevier, 1983-11)
The effects of strain rate of loading including impact on the bending properties of steel fibre reinforced mortar are studied using an instrumented drop-weight impact machine. Particular emphasis is put on clarifying the ...
Modulation of glucose transport in human red blood cells by ATP
(Elsevier, 1983-01-19)
Depletion of energy stores of human red cells decreases the maximum transport capacity, Jm, for glucose transport to a value one-third or less of that found in red cells from freshly drawn blood. There is no change in Km. ...
Complexes of copper and silver with tetracyanobiimidazole
(Elsevier, 1983)
We have recently reported the synthesis and properties of a remarkable new ligand 4,4',5,5'-tetracyano-2,2'-biimidazole (H2Tcbiim).1 This acidic ligand readily binds metal ions in its dianionic form and appears to act as ...
