The history of the use and identification of Cannabis sativa L. is long and complex. It is one of the oldest cultivated plants, used for the production of oil from the seeds, and fibre from the stems for rope and fabrics, and has long been used as a psychoactive drug due to the presence of cannabinoids in the resins produced by the plant. Indeed, there is evidence of cannabis use from Neolithic burial sites. The name Cannabis sativa was first used in Linnaeus Genera Plantarum in 1753, but since that publication there has been considerable debate about the number of species and varieties that exist - this has been recently summarized succinctly by Gigliano [1]. The debate has centred on (i) the characteristics of the fruit, and (ii) meiosis and pollen fertility. It is now generally accepted, however, that there is only one species, namely Cannabis sativa L., which exhibits great diversity due to both selection in the wild and in the cultivated environment. [Pg.49]

The decision to implement this solution might be made in 2004, with the intent of having the first reactor on line in 2012. A site will be selected for the research and development center and two permanent reactor fabrication facilities, one on each coast. These facilities will be equipped with the heavy machinery and instrumentation necessary for the construction of high quality, low cost fusion reactors. Early planning and construction will include provisions for the rapid and orderly production of a series of reactors after the final design is fixed. [Pg.177]

Fabrication of an enzyme-modified electrode, and indeed any biosensor, requires stepwise selection and integration of a number of complex components. First, the redox enzyme chosen must have the required selectivity for the analyte as well as a product that is detectable at the signal transducer (in this case the electrode surface). A search of the literature reveals that a relatively small number of enzymes have been reported as functional on biosensors, and two classes of enzymes (oxido-reductase and dehydrogenase) predominate. Notably, the oxido-reductase family, and glucose oxidase in particular, account for the majority of all reports in the literature. Other factors that complicate the choice of enzyme include the necessity for a derivatization procedure that does not destroy the active site of the enzyme. In some cases, proper orientation of the enzyme s active site must also be considered. Glutamate dehydrogenase, a protein whose conformation (and therefore activity) is dependent on electrostatic forces, has been... [Pg.403]
