Albumin is a protein made by the liver. It makes up about 60% of the total protein in the blood and plays many roles. It keeps fluid from leaking out of blood vessels; nourishes tissues; and transports hormones, vitamins, drugs, and ions like calcium throughout the body.
The Mayan and other Mesoamerican cultures used a vigesimal number system based on base 20 (and, to some extent, base 5), probably originally developed from counting on fingers and toes. The numerals consisted of only three symbols: zero, represented as a shell shape; one, a dot; and five, a bar.he Mayan civilisation had settled in the region of Central America from about 2000 BCE, although the so-called Classic Period stretches from about 250 CE to 900 CE.
A typical Mayan date looks like this: 1  12.18.16.2.6, 3 Cimi 4 Zotz. 2  12.18.16.2.6 is the Long Count date. 3  3 Cimi is the Tzolk'in date. 4  4 Zotz is the Haab date.
