the World Heritage site of Timbuktu, once a cradle of Islamic learning, has 16 cemeteries and mausolea, according to the UNESCO website.

Sometimes called the city of 333 saints, Timbuktu is also home to nearly 100,000 ancient manuscripts, some dating back to the 12th century, preserved in family homes and private libraries under the care of religious scholars.

At its height in the 1500s, the city, a Niger River port at the edge of the Sahara 1,000km north of Bamako, was the key intersection for salt traders travelling from the north and gold traders from the south.1. Field of the Invention
This invention concerns large, lightweight, inflatable structures such as satellite decoys and ship decoys. More particularly, this invention relates to inflatable tubes used as supports in such structures.
2. Description of the Prior Art
Large, lightweight, inflatable structures find various applications. Generally speaking, these devices need structural members as reinforcement. Conventional ship decoys or satellite decoys are large, inflatable structures which typically employ internal inflatable tube frames for structural support.
The sizing of the tubes in such a tube frame is determined, at least in part, by the cross sectional area moment of inertia. In other words, a tube size is conventionally chosen to prevent the tubes from buckling and thereby keeping the decoy from collapsing under its own weight.
With a large cross section, a tube in
