Polarographic Studies of Some Lanthanoids(III) inN,N-Dimethylacetamide

Polarographic Investigation of Some Cytokinins

The cytokinins constitute one of the five groups of plant hormones, and are characterised by their ability to promote cell division in cultured plant callus tissue under appropriate conditions [I-31. With the exception of diphenylurea, all cytokinins that have been unambiguously identified in extracts of higher plants are derivatives of adenine, including 6-aminoand riboside-substituted compoun...

Polarographic Studies of Human Blood Sera

R. BrdiEka, in 1937, in a note to the editor of Nature (1), reported the application of the polarographic method to cancer diagnosis, through the measurement of certain sulphur-containing amino acids present in the proteins in human blood serum. Brdicka made tests on the serum from 67 different persons; 32 of these gave an abnormally low polarographic protein effect. These 32 cases were shown b...

A polarographic study of some stilbene derivatives of biological interest.

Polarographic Methods of Analysis

The polarographic method invented by J. Heyrovsk over 40 years ago has been associated with many successful achievements in many branches of physical and analytical chemistry, particularly in electrochemistry. Following the construction of the polarograph (with the excellent properties of Kuera's dropping mercury electrode incorporated) by Heyrovsk and Shikata, recording the current—voltage cur...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
