  • 5. Dr. K. Shiva Rama Prasad, at http://www.technoayurveda.com/ Definition of Scientific paper • An accepted original scientific publication containing scientific information to enable peers: 1. To assess observations 2. To repeat experiments 3. To evaluate intellectual processes 4. Must have an impact 5. Available to scientific community without restriction 6. Available for regular screening by one or more of the major recognized secondary services (Biological abstracts, Index Medicus, Pub Med etc…) Scientific writing
  • 6. Dr. K.

  • 9. Dr. K. Shiva Rama Prasad, at http://www.technoayurveda.com/ Behave ethically Research ethics – declaration of Helsinki, ICH Publication ethics avoid misconduct protect patients’ identities report clearly: informed consent any deviation from usual practice full burden imposed on participants total risks posed to participants or others benefits to participants, patients, society It’s not always enough to state that the study was approved by an ethics committee or IRB Scientific writing

Shiva Rama Prasad, at http://www.technoayurveda.com/ Components of the discussion • Try to present the principles, relationships, and generalizations shown by the Results • Point out any exceptions or any lack of correlation and define unsettled points • Show how your results and interpretations agree or contrast with previously published work • Discuss the theoretical implications of your work, and any possible practical applications. • State your conclusions as clearly as possible • Summarize your evidence for each conclusion Scientific writing
  • 27. Dr. K. Shiva Rama Prasad, at http://www.technoayurveda.com/ References • Referencing is a standardized way of acknowledging the sources of information and ideas that you have used in your document. • A list of ALL the references used in the text must be written. • Reference format varies widely: – Harvard format (the name and year system) is the most widely used – Alphabet-Number system is a modification of name and year system – Citation order system – Vancouver referencing method Scientific writing

Avoid abusing word forms. 6. Do not use more words where fewer will do. * Writing good scientific papers IMM, Mainz, Scientific writing
  • 32. Dr. K. Shiva Rama Prasad, at http://www.technoayurveda.com/ Conclusion 7. Use an outline to organize your ideas and writing 8. Think about the structure of paragraphs 9. Pay attention to tenses. 10. Captions should not merely name a table or figure, they should explain how to read it. 11. When citing a reference, focus on the ideas, not the authors. 12. Show us don't tell us. 13. Write about your results, not your tables, figures, and statistics. * Writing good scientific papers IMM, Mainz, Scientific writing
  • 33. Dr. K. Shiva Rama Prasad, at http://www.technoayurveda.com/ Conclusion 14. Develop a strategy for your Discussion. 15. Introductions and conclusions are the hardest parts. 16. Break up large projects into small pieces and work on the pieces. 17. Make your writing flow and resonate. 18. Use word processors effectively and back up your work religiously. • 19. Take editorial comments seriously. * Writing good scientific papers IMM, Mainz, Scientific writing
