Details on the institution where the work was done are requested and should be given above the title. Complex surveys or materials for further education should be preceded by an outline of topics. This should indicate the question under investigation which is generally based on a brief interpretation of the literature considering the current state of knowledge in the subfield and explaining the necessary theoretical foundations. It should not repeat results already given, but should state the conclusions drawn from the results or provide a theoretical debate and comparison with literature citations. This part contains the instruction and experimental conditions.
All directions are brief, yet detailed enough for guidance.
Unless directions taken over from literature have been altered, it suffices to refer to the location in the original source. In other parts of the paper this is not desirable. Results of elemental analyses can be omitted if it is stated that all the results were in an acceptable error range. Short communications are published as rapidly as possible. Only the surnames of authors are given in the text.
