Our geologic time scale was constructed to visually show the duration of each time unit. This was done by making a linear time line on the left side of the time columns. Thicker units such as the Proterozoic were longer in duration than thinner units such as the Cenozoic. We also have a printable version of the Geologic Time Scale as a .pdf document. You can print this timescale for personal use. Author: Hobart M. King, Ph.D.
The definition of import is to introduce or bring goods from one country to be sold in another. 1  An example of import is introducing a friend from another country to deep fried Twinkies.  An example of import is a shop owner bringing artwork back from Indonesia to sell at their San Francisco shop.
Parallel import means that patented or marked goods are purchased in a foreign market and resold in the domestic market. These are known as passive parallel imports. Instead, active parallel imports occur when foreign licensees enter the market in competition with the holder of the patent or of the trade mark. There are three kinds of principles that can hypothetically regulate the parallel importations (known also as gray market).
