The application of optical rot,atory dispersion to nucleic acids and polynucleotides is fairly recent (l-6). Doty et cd. (2) made a comprehensive study of the optical rotatory dispersion of deoxyribonucleic acid, ribonucleic acid, and complexes of some homopolynucleotides; their results strongly suggested a close relationship between the optical rotations and the secondary structure of nucleic ...

Only 3 of the 6 sulfhydryl groups of native bovine heart supernatant malate dehydrogenase (S-MDH) react with p-mercuribenzoate (PMB) with no loss of enzymatic activity. In addition, prolonged incubation of S-MDH in 2.6 M urea solutions does not significantly alter the catalytic properties of the enzyme. In 2.6 M urea, however, all 6 sulfhydryl groups of the enzyme react with PMB, with attendant...

The optical rotatory properties of a myeloma globulin, immunoglobulin G (IgG), and a normal individual IgG in the far ultraviolet were investigated by rotatory dispersion, circular dichroism, and absorption spectroscopy. The optical rotatory dispersion of the myeloma immunoglobulin displayed two peaks, one at 205 ml* and the other at 210 rnp, and a trough at 228 mp, a lesser one at 230 mp, and ...

In this paper, a newly proposed analytical scheme by the authors namely the improved di erential transform method is employed to provide an explicit series solution to the Thomas Fermi equation. The solution procedure is very straightforward, requiring merely elementary operations together with di erentiation, and ends up in a recursive formula involving the Adomian polynomials to a ord the unk...

A derivation of the Dirac equation in ‘3 + 1’ dimensions is presented based on a master equation approach originally developed for the ‘1+ 1’ problem by McKeon and Ord. The method of derivation presented here suggests a mechanism by which the work of Knuth and Bahrenyi on causal sets may be extended to a derivation of the Dirac equation in the context of an inference problem.

It is well recognized that the measurements of optical rotatory dispersion of proteins with strong absorption bands are extremely difficult because of the diminishing intensity of the emergent light. Until very recently, these studies were made possible only by improving the light source and also frequently by a wide opening of the slit width on the monochromator at the expense of spectral puri...
