Spatial Data Objects. The geometry and geography data types support sixteen spatial data objects, or instance types. However, only eleven of these instance types are instantiable; you can create and work with these instances (or instantiate them) in a database.
Rewiring the grain. Metabolic engineering. Golden Rice technology is based on the simple principle that rice plants possess the whole machinery to synthesise Î²-carotene, and while this machinery is fully active in leaves, parts of it are turned off in the grain.
In fact, the natural fatty lipids in golden rice aid in the absorption of beta-carotene, even when little or no oil is added to it. When oil is added to rice it helps your body absorb the carotenoids in it, but in the case of golden rice oil is not necessary to reap the benefits.
