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.
The Phoenicians arrived by ship and blended with the Cretans over a period of time, settling themselves, planting vineyards, olive groves and villas-essentially the Minoans were the children of them both, with many elements drawn from old Cretan society, but taking on the majority of Phoenician principles and rules.uestions on Minoans and Phoenicians contact with each other. Minoans rise to prominence seems to come around the of 2000 BC roughly. The Phoenician site of Byblos has been settled since 6000 BC, while the city of Tyre has been in use since 2700 BC.
