Search Form:   This is a Boolean search engine. It is therefore advisable to use generic terms (instead of, e. g., whole sentences). Please don't enter conjunctions like "and" as they are provided automatically by the search mode buttons. Search Mode: "AND" "OR" Instead of using this engine covering the websites "medical-cybernetics.de", "medizinische-kybernetik.de" and "spina.medical-cybernetics.de" you may also want to search the spezialized index periodicorum database for scientific journals on medical cybernetics.
