A direct-elution technique for the recovery of thin-layer samples
(Elsevier, 1978-01)
An elution technique is described which permits the recovery of samples from flexible thin-layer chromatograms without removal of the layer from the plate. This simple method avoids many of the problems associated with ...
An investigation of the maximum experimental safe gap anomaly
(Elsevier, 1979)
The "safe gap" is defined as the maximum gap between two close-fitting, flat, machined metal surfaces that will just prevent an explosion within a vessel from producing a propagating combustion wave in the gases that ...
Assignments of the n[pi]* singlet states of p-benzoquinone
(Elsevier, 1974-03-30)
The vapor phase fluorescence spectra of p-benzoquinone-h4 and d4 are reported and discussed in relation to the assignment of the low lying singlet states. The low temperature, polarized single crystal electronic absorption ...
Separation of bile acids from neutral lipids on thin-layer chromatograms
(Elsevier, 1974-11-13)
Solute concentration in the kidney-- I. a model of the renal medulla and its limit cases
(Elsevier, 1976)
We develop a general model of the renal medulla that is similar in geometry to the models reported by others. Two solutes are assumed to be present, one to play the role of salt and the other that of urea and similarly ...
A game to help students comprehend enzyme structure and mechanism of action
(Elsevier, 1976-01)
Partial characterization of Ia antigens from murine lymphoid cells
(Springer-Verlag; Springer-Verlag New York Inc., 1974-12)
Congenic anti-Ia antisera were used to bind radiolabelled Ia antigens from cells of various strains of mice of known H-2 haplotype. The results indicate that Ia antigens are proteins of molecular weight 30,000 to 35,000 ...
