Copper is an essential trace element in plants and animals, but not some microorganisms. The human body contains copper at a level of about 1.4 to 2.1 mg per kg of body mass. Stated differently, the RDA for copper in normal healthy adults is quoted as 0.97 mg/day and as 3.0 mg/day. Copper is absorbed in the gut, then transported to the liver bound to albumin. After processing in the liver, copper is distributed to other tissues in a second phase. Copper transport here involves the protein ceruloplasmin, which carries the majority of copper in blood. Ceruloplasmin also carries copper that is excreted in milk, and is particularly well-absorbed as a copper source. Copper in the body normally undergoes enterohepatic circulation (about 5 mg a day, vs. about 1 mg per day absorbed in the diet and excreted from the body), and the body is able to excrete some excess copper, if needed, via bile, which carries some copper out of the liver that is not then reabsorbed by the intestine.
How is copper absorbed in humans?
****
The answer: in the gut

Others argue that reason was generally held in high regard during the Middle Ages. Science historian Edward Grant writes, "If revolutionary rational thoughts were expressed [in the 18th century], they were only made possible because of the long medieval tradition that established the use of reason as one of the most important of human activities". Also, contrary to common belief, David Lindberg writes, "the late medieval scholar rarely experienced the coercive power of the church and would have regarded himself as free (particularly in the natural sciences) to follow reason and observation wherever they led".
According to Grant, the medieval use of reason was the forerunner the revolutionary rationalism of what century?

Cork has been culturally diverse for many years, from Huguenot communities in the 17th century, through to Eastern European communities and a smaller numbers from African and Asian nations in the 20th and 21st centuries. This is reflected in the multi-cultural restaurants and shops, including specialist shops for East-European or Middle-Eastern food, Chinese and Thai restaurants, French patisseries, Indian buffets, and Middle Eastern kebab houses. Cork saw some Jewish immigration from Lithuania and Russia in the late 19th century. Jewish citizens such as Gerald Goldberg (several times Lord Mayor), David Marcus (novelist) and Louis Marcus (documentary maker) played notable roles in 20th century Cork. Today, the Jewish community is relatively small in population, although the city still has a Jewish quarter and synagogue. Cork also features various Christian churches, as well as a mosque.
