The fruit of a shrub that grows in Sierra Leone is very toxic and has been used as a rat poison. The toxic principal has been identified as Z-18-fluoro-9-octadecenoic acid. Suggest a synthesis from 8-fluorooctanol, l-chloro-7-iodoheptane, acetylene, and any other necessary organic or inorganic reagents. 

Mining and mineral processing operations at the Sierra Leone (Africa) mine are based on a series of relatively large, highly complex ore bodies characterized by a wide variation in mineral composition and mineral size distributions.

In the course of chemical investigation on Tabernaemontana, Achenbach et al. (116) isolated from T. glandulosa, from Sierra Leone and Nigeria, two new alkaloids, tabemulosine (42) and 12-demethoxytabemulosine (43). 

As of July 2006, 164 nations accounting for 61.6 percent of the world s carbon dioxide emissions had ratified or accepted the treaty. About 30 (mostly small) nations have never taken a position on the treaty. These nations include Afghanistan, Andorra, Angola, Brunei, Central African Republic, Chad, Comoros, Gabon, Iraq, Saint Kitts and Nevis, San Marino, Sao Tome and Principe, Serbia, Sierra Leone, Tajikistan, Timor-Leste, Tonga, Turkey, Zimbabwe, Republic of China (Taiwan), and Vatican City. Only two nations have signed but declined to ratify the treaty, Australia and the United States.

As in the case of ilmenite, the largest producers are in Australia, the Republic of South Africa and Sierra Leone. There is not enough natural rutile to meet demand, and it is therefore gradually being replaced by the synthetic variety. In 1994 the world wide production of rutile was about 0.5 x 106 t of contained Ti02. Compositions of typical rutile concentrates are given in Table 14. 

African ginger, primarily from Sierra Leone, is mainly used in meat-seasonings and has an average volatile oil content of 1.6%.

Features The oblong-conical shaped pods are fiery to the taste, and the numerous seeds contain a large amount of oil, which has a similar effect on the palate. The fruit itself, however, differs widely in size, colour and strength. The yellowish-red product of Sierra Leone is the most pungent, the long, bright red type from Japan being much milder.
