Front & Back Matter

Provide on a separate page an abstract of not more than 250 words. This abstract should consist of four paragraphs, labeled Background, Methods, Results, and Conclusions. They should briefly describe, respectively, the problem being addressed in the study, how the study was performed, the salient results, and what the authors conclude from the results. The text should be arranged in the following sections: Introduction, Material and Methods, Results, Discussion, Acknowledgement, References. Footnotes: Avoid footnotes. When essential, they are numbered consecutively and typed at the foot of the appropriate page. Tables and illustrations: Tables and illustrations (both numbered in Arabic numerals) should be prepared on separate pages. Tables require a heading and figures a legend, also prepared on a separate page. For the reproduction of illustrations, only good drawings and original photographs can be accepted; negatives or photocopies cannot be used. Due to technical reasons, figures with a screen background should not be submitted. When possible, group several illustrations on one block for reproduction (max. size 180 223 mm) or provide crop marks. Each illustration must be labeled with its number and the author’s name. Electronically submitted b/w half-tone and color illustrations must have a final resolution of 300 dpi after scaling (final size), line drawings one of 800–1,200 dpi. Figure files must not be embedded in a document file but submitted separately (see detailed instructions at www.karger.com/iaa/). Color illustrations Online edition: Color illustrations are reproduced free of charge. In the print version, the illustrations are reproduced in black and white. Please avoid referring to the colors in the text and figure legends. Print edition: Up to 6 color illustrations per page can be integrated within the text at CHF 800.– per page. Abbreviations: Avoid overuse of abbreviations. Introduce an abbreviation only when the same term occurs three or more times.
