Serial

All terminology used should comply with the recommendations of the IUPAC – www.iupac.org/reports/ and www.iupac.org/publications/. For the use of quantities, units, and symbols, the following documents are recommended:

• www.iupac.org/publications/books/gbook/green_book_2ed.pdf,
• www.iupac.org/reports/1993/homann/index.html.

A very good overview of the nomenclature in organic chemistry and biochemistry is available at www.chem.qmul.ac.uk/iupac/.

Tables and figures should be numbered, starting from 1. They should be embedded within the document, approximately in the place, where they should appear in the publication. Figures should be pasted into the Word document so that they could be edited using the software in which they were created. Schemes and charts with complex reactions and compounds, respectively, are considered figures and numbered consecutively in order of appearance in the text. Chemicals are denoted by roman numerals according to their order of appearance in the text.Figures must be supplied in the true reproduction size, as legible black-and-white vector graphics or bitmaps with the minimum resolution of 900 dpi. Color bitmaps are accepted for the electronic version of the journal but the authors are charged for the color print. It is recommended to optimize the size of the color palette used in order not to increase the file size exorbitantly. At sending the final, revised manuscript, each bitmap figure should also be sent as a separate file in a bitmap format (bmp, gif, tif, jpg, eps).

Figure below illustrates the recommended form of graph and its caption. The symbols of variables must have the same form and style as in the main text. It is recommended to label curves by a short intelligible symbol, especially, if the plot contains several curves. The symbols used must be explained in the figure caption. The so-called Type 1 fonts, which include the most frequently employed ones, such as Arial, Helvetica, Times New Roman, should be used for the axis description. The recommended fonts are Arial or Helvetica or Times New Roman. Some deviations from this form are allowed, if a unified form of figures is used within the manuscript.

If several plots are included into one figure, they should be distinguished by letters in the left-hand (right-hand, in case of the lack of space) top corner of the plots (Figs. 3a and 3b). It is recommended to use the symbols of variables not their names in the axis titles. The axes values should not have more than three digits. In order to avoid that, the axis quantity should be multiplied by an appropriate factor. If numerous symbols are used repeatedly throughout the main text, these should be listed in a separate chapter. All symbols, names, and units of variables used throughout the manuscript must be included in alphabetic order.

References Literature references should be listed alphabetically, typed double-spaced, and in the text referred to by author name and year of publication enclosed in parentheses, e.g. (Fišera 1989; Blacksmith and Hargreaves 1999, Devera et al. 2009). Citations of personal communications and unpublished data should in text appear only as: (J. Biely, personal communication), (J. Švitel, unpublished), and not in the reference list.

References should contain: author(s) name(s) followed by author(s) initials, year, journal, volume number, and inclusive page numbers. Books must include the location and name of the publisher.

Examples:

(1) Periodicals: Gonzalez AE, Martinez AT, Almendros G, Grinbergs J (1989) Acta Chimica Slovaca 5: 221-236;

(2) Books (edited by someone other than author of article): Slovák AB, Andrej CD, Brondoš M, Nikto O (1975). In: Haľama D (Ed) Basics of Biotechnology, Vol 1 (pp 9-36). Slovak Academic Press, Bratislava;

(3) Books (Monographs): Ninnemann BA (1973) Fundamental Concepts in Photochemistry. Freiherr and Obermeyer, Berlin.

Tables  Each table should be typed on a separate page. Tables should be numbered with Arabic numerals, followed by the title. Both horizontal and vertical rules should be indicated. Table footnotes should be marked with superscript numbers. Each table must be mentioned in the text.

Figures Each figure should be mentioned in the text. Line drawings must be in black on white background, and should not contain shading (1 pts line are recommended).  Extremely small type should be avoided as figures are often reduced in size (usually by factor 2). 36 pts types are recommended.  Symbols should have the magnitude of 8-10 pt. Photographs should be supplied as black-and-white high contrast glossy prints.  Halftone reproductions must be clear, well-contrasted glossy prints trimmed at right angles: original halftones must be supplied with each copy of the manuscript. Colour plates cannot be accepted. Figures as well as legends should be identified by Arabic numbers and headed "Fig. 1', etc. Where multi-part figures are used, each part should be clearly identified in the legend, preferably with (lower case) letters. Do not give magnification or scales in the figure legends: instead draw bar scales directly on the figures.

Abbreviations and units SI units should be used, e.g.: mg, g, kg, km, m, cm, mm, ppm, cpm, qmCi (microCurie), L (litre), mL, s (second), min (minute), h (hour), mol, m³, kg per ha or kg ha^-3. If a non-standard abbreviation is to be used extensively, it should be defined in full on page 2 and follow the abstract.

Proofs and off-prints The author will be sent proofs for proofreading in electronic forms. Authors should arrange the text to the camera-ready form. No off prints of the article will be supplied. The .pdf file of the final form of the article will be available to author(s).

Do's

1. File. Identify your file clearly with a sensible name. Make absolutely sure that you send us your final version, and that the printout is identical to what you have saved on the diskette.
2. Consistency. Be absolutely consistent and check the use of punctuation, abbreviations, capitals and lower case in headings, spelling, etc. If possible, use the spelling checker on your computer.
3. Special characters. Use “Insert” function to insert special characters into the text.
4. Headings. Start headings etc. flush left, with two space lines above (i.e. three Hard Returns) and one space line below (two Hard Returns). Distinguish different levels of headings and be consistent.
5. Paragraphs. Indent all paragraphs with a `TAB` code, and separate them from one another with one Hard Return.
6. Block quotations should be indented with an `Indent` code and should have one space line (i.e. two Hard Returns) above and below.
7. Figures should be submitted in camera-ready form. The position of the figure in the text should be indicated in the margins of the hard copy. Figure legends should be placed at the end of your file.
8. Tables. We prefer tables to be submitted in camera-ready form. If you also put your tables on diskette, please separate columns with `TAB` codes (not with spaces) and, consequently, adjust the tabular stops to position the columns.
9. Equations. One-line equations without fractions can be typeset from the diskette when they are keyed in as plain text.
10. References and Notes. Strictly follow the Instructions for Authors of the journal in which the article will be published for the style of referencing and the use of notes.

Don'ts

1. Hyphenation. Do not hyphenate words at the end of a line. Use only one hyphen for words such as ``well-being'', and ``re-do'' and use two hyphens for sequences of dates and years such as ``conference dates are 12-15 September, 1992'', ``age groups between 20-30 years are welcome'', and page number indications in References, e.g. ``pp. 240-243''.
2. Hard Returns. Do not use Hard Returns except when absolutely necessary, such as at the end of paragraphs, headings, etc. Otherwise, let the word wrap feature of your word processor do this work for you.
3. TAB feature and Spacebar. If you need more than one space between two items, e.g. when you write in columns, always use the `TAB` feature of your word-processing package. Use the spacebar only for separating words from one another. Do not use the spacebar to format tables, for centring or lying out texts, or for any other form of line or page formatting.

Proceeding Manuscript / Delivering your article

The authors are suggested to use a manuscript template  containing also the detailed instructions. An accompanying letter should contain a proposal of 3 suitable reviewers. Label your file properly, giving exact details on operating system and software used. Always retain a backup copy of your file. Send the file to one of journal editors by e-mail as attachment. When your article will be accepted for the publication, incorporate all reviewers’ comments into the text. Arrange the manuscript to the camera-ready form (with embedded Figures and Figure Legends, Tables, Notes, etc.  Please keep deadlines ordered by editors. Send to the Editors a signed copyright transfer agreement. Wait on the acceptance letter and the final .pdf file of articles.
