It takes approximately 48 to 72 hours for your level of hCG to double its levels. What this means for you depends on your body. If your level of hCG prior to pregnancy is 2 miU, it might take two to three days for it to double to 4 mIU and another two to three days for that to double to 8 mIU. This means it could take a week for the most sensitive pregnancy test to determine whether or not you a pregnant.
Navigation at Sea, History of. The first Western civilization known to have developed the art of navigation at sea were the Phoenicians, about 4,000 years ago (c. 2000 B.C.E. ). Phoenician sailors accomplished navigation by using primitive charts and observations of the Sun and stars to determine directions.
Long after Phoenician culture flourished, or Phoenicia existed as a political entity, Hellenized natives of the region where Canaanites still lived were referred to as Syro-Phoenicians, as in the Gospel of Mark 7:26: The woman was a Greek, a Syro-phoenician by birth.he Phoenicians were famous metalworkers, and by the end of the 8th century BC, Greek city-states were sending out envoys to the Levant (the eastern Mediterranean) for metal goods. The height of Phoenician trade was around the 7th and 8th centuries.
