ekstrusiossa

Could you clarify what you mean by "ekstrusiossa"? Specifically:

- Which language is the term from, and what is its exact meaning?

- Which field or topic should the article cover (for example, extrusion in materials science, a dental or medical term, linguistics, geography, or something else)?

- Do you want the article written in English, or in another language such as Finnish or Lithuanian?

If you prefer, I can proceed with a concise, neutral article about extrusion in materials science and related terminology, but I want to ensure I address the correct concept you have in mind.
