The title of article should be brief and the full authors name and surname should by indicated together with the affiliation and address. Respective addresses of co-authors must be clearly cross-referenced. The body of the manuscript should be preceded by an abstract limited to about 8 lines, followed by up to 6 keywords. The papers should be reasonably subdivided into sections and, if necessary, to subsections. For scientific contributions the following scheme is recommended.

1 INTRODUCTION - the topic of the article should be defined clearly and short review of published relevant solutions and comparison with the authors results should be given.

2 THEORETICAL PART - the author presents his considerations and ideas, mathematical formulae and their derivation. All information taken from other authors or critical comments on other works should be accompanied by exact references.

3 EXPERIMENTAL PART - includes the data on the measuring method and instruments as well as experimental results. In purely theoretical works this part is omitted.

4 DISCUSSION - presents a critical analysis, interpretation and evaluation of the obtained results.

5 CONCLUSION - the results should be summarized briefly and authors scientific contribution should be indicated.

6 REFERENCES - must be fully and accurately documented and conform with standard accepted in other journals. References should be quoted in the text in square brackets and listed at the end of the paper in the order they have appeared in the text.

7 AUTHOR(S) BIOGRAPHY - 10 to 15 lines about the author(s). The recommended content is: (titles, in parentheses) the year and place of birth, type of education and scientific degrees attained (field and year). Former and present affiliations and professional (research) interests and activities.

The aim of publishing short scientific communications is to ensure the priority, through publishing, even though this might be at a cost of completeness in treating and discussing the topic.

The short communication need not to have all sections recommended for original scientific articles. At the end, again authors original contribution should be stated explicitly.

No hard copies of the manuscript are required, however it is welcomed if manuscripts, 80 types on the line and 35 lines a page in a single-column format are submitted. This corrersponds to Times 11pt font, and approximatelly one such a page (plane text, without figures) would fit to one Journal page.

Figures and illustrations are required to be PC processed. It is appreciated if they are also embedded into the text for the reviewers convenience, but in any case the figure captions should be given in the text near the positions where the figures are to appear. Beside this, figures and illustrations should be delivered all in one separate document (file). Please send the matters exclusively by E-mail.

Concerning the graphs, we prefer vector formats eg .eps, .wmf, .cgm, .cdr, bitmap formats as .pcx, .bmp, .tif or any other should be avoided except in case of submitting photographs or alike pictures. Please realize that sending a bitmap picture as an *.eps file would not do! Further, consider that the figures can be of one-column width (usually less than 8 cm) or, exceptionally (not exceeding 16 cm) of two-column width. The lettering should be done using Times New Roman font.

Typed tables are not regarded as figures. They have to be numbered separately (Tab.1, Tab.2, etc) with all necessary text or comments placed above them.

After the evaluation by two independent peer reviewers and eventual changes made in submitted papers, please, return the final version, via E-mail, including the figures (in above listed formats) as an MS-Word file (not a *.pdf) or preferably prepared by LaTeX or TeX editor since the latter is used for the Journal compostion.

Every author will receive free issue of the Journal and author(s) will be provided with 10 reprints per the article.
