Long DescriptionHumanity's Burden provides a panoramic overview of the history of malaria. It traces the long arc of malaria out of tropical Africa into Eurasia, its transfer to the Americas during the early years of the Columbian exchange, and its retraction from the middle latitudes into the tropics since the late nineteenth century. Adopting a broadly comparative approach to historical patterns and processes, it synthesizes research findings from the natural and social sciences and weaves these understandings into a narrative that reaches from the earliest evidence of malaria infections in tropical Africa up to the present. Written in a style that is easily accessible to non-specialists, it considers the significance of genetic mutations, diet, lifestyle, migration, warfare, palliative and curative treatment, and efforts to interrupt transmission on the global distribution of malaria.

This symbology was developed by the Plessey Company in England. A variation of Plessey was used by the ADS Company and is known as Anker Code. Anker Code was used in European point of sale systems prior to the advent of EAN. Another variation is known as the MSI Code.

Plessey offers a full range of HEX digits 0-F. The bit pattern of the bits sets the high order bit at the right which is reverse of how we normally think of bits these days. (MSI puts the high order bit on the left).

The start bar is always "D" (1101) and the terminator can be two binary 1's (11) if the barcode is to be read from left to right only. If the barcode can be read in either direction the terminator will be a single binary 1 (1) and is followed by a reverse of the start character or the "B" (1011).

You can use the stripe bits can be used to generate the graphic pattern. If you want to see this trick, check out the MSI Code page. Plessey uses a cyclic (or polynomial) check code technique which is applied to the reading of barcode labels and transmission of data. This technique is a fair compromise between the extra redundancy and the error detecting power. Roughly one undetected error per hundred million 6 digit transactions.
