läpimenot

I’m happy to write a wiki-style article, but I’m not certain what meaning of “läpimenot” you have in mind. In Finnish, the term can vary by field, and providing the correct focus will help me keep the article concise and neutral. Could you specify the intended context or field (for example, materials science/chemistry, computing/telecommunications, traffic engineering, or another area)? If you have a particular definition or source in mind, please share it and I’ll base the article on that.
