Translation of "twofold" into Estonian

A duplicated twofold dilution series of homologous bovine reference antiserum.

Veise homoloogilise võrdleva antiseerumi kaks kahekordse lahjendusega seeriat.

The geopolitical position of Estonian with respect to this is twofold. On one hand, we are part of NATO and the EU - this is at least grounds for hope of diplomatic and military support. On the other hand, our history and geographical placement serve as reminders that the guarantees of the West might be politicial, may not be taken for granted, are certainly not ironclad.

Eesti geopoliitiline positsioon selles on kahetine. Ühelt poolt oleme NATOs ja Euroopa Liidus – see annab vähemalt lootust diplomaatilisele ja sõjalisele katusele. Teiselt poolt on meie ajalugu ja geograafia meeldetuletuseks, et Lääne garantii võib olla poliitiline, mitte automaatne, kaugeltki mitte raudkindel.
