networks (Newman 2003 ). Visualizing and gauging a network of scientific knowledge is an emerging area of interest (Blatt 2009 ; Perianes-Rodríguez et al. 2010 ; Zhao and Wang, 2011 ). Scholars have developed and employed diverse approaches and
The use of thin-layer chromatography (TLC) for separation, identification and quantification of different organic and inorganic substances is limited by the visualization of the separated and determined substances. In literature, there are innumerable references which present chemical, physical and biological methods of visualization of different kinds of organic and inorganic substances, especially the ones which do not absorb visible light. However, scientists are looking for new, more efficient reagents for a selective visualization of the definite part of a substance or, in some cases, for a specific determination of specific substances. This article describes a different method of visualization of the substances separated on the TLC plates. Special attention was paid to the different chemical reaction applied to obtain colour substrates of the reaction between separated substances and the property of the chosen derivate reagents. Describing different methods of visualization we tried to compare different groups of the determined substance, using different methods of their visualization. The analysis shows, for the first time, that different types of substances need different types of reactions and different types of reagents. The results of the TLC detection of the broad spectrum of the representative classes of organic derivatives are presented in table. The data illustrate the possibilities of TLC differentiation of the organic compounds which contain different active groups. The most unusual effect was obtained during the TLC application of the induced detection reagent. As a matter of fact, some sulphur atoms in their molecules are able to induce the iodine-azide reaction.

complex nature of metamodeling. In the case of multi-level metamodeling, the situation is even more challenging as concepts of different abstraction levels are to be visualized in the same system. The lack of appropriate visualization hinders the
of a discipline. So it has an important reference value for promoting development of academic disciplines.
After nearly 40 years of development, visualization methods gradually are being used in co-word analysis to reveal the development and
study of information visualization starts with computer graphics and its goal is to represent abstract information spaces intuitively and naturally. Domain visualization is one of the new research fronts resulted from the proliferation of information
A vapour phase bromination procedure using80mBr and82Br has been investigated for reaction with unsaturated lipids present in a fingerprint deposit. The reaction is rapid and
in combination with autoradiography provides a promising technique for the visualisation of latent fingerprints particularly
under conditions which preclude the application of other methods. Preliminary work on the degradation of fingerprint constituents
by UV and water is reported with comparative studies using the35SO2 reaction.
The goal of this paper is to use citation analysis and visualization to give a scientometric overview and survey of the diversity and spread of the domain across its various sub-domains, in general, and to identify key concepts, which are mutual to the
