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 Phoenician People. The Phoenicians were a seafaring trading company who called themselves Canaanites, meaning merchant, which describes the Phoenicians very well. T he Canaanite civilization began to develop in the modern day land which is Lebanon, parts of Syria and Israel, circa 3000 B.C.he Phoenicians traded with the Greeks, and shared the alphabet with them. The original Phoenician alphabet had 22 letters, and was adopted by the Greeks, who added four letters, all 26 of which we use today.
