Abstract: This application provides an arecoline salt and a preparation method and a product thereof. The arecoline salt is a benzoate of arecoline, with a structural formula shown as follows: where X is a molar ratio of arecoline to benzoic acid. The arecoline salt, with good physicochemical stability, is convenient to use and widely used.

Abstract: This application provides an areca nut-flavored product, containing an arecoline salt. Because an arecoline salt is used in the product, a user absorbs arecoline when consuming the product, and an effect similar to chewing areca nuts is produced, with relatively little irritation.

Abstract: Method and apparatus for optimizing spare component management for a network having a plurality of nodes is described. In one example, availability parameters associated with an inventory of spare components are obtained. A plurality of management configurations are determined in response to the availability parameters. Each management configuration includes at least one warehouse node selected from the plurality of nodes in the network and a quantity of spare components in the inventory that are to be stored at the at least one warehouse node.

Abstract: A toroidal fusion device with an elongated axial cross section is described which is capable of ignition without auxiliary heating and with modest toroidal magnetic field. The device is based on the principle that for elongated toroids the toroidal current density in the plasma at ignition is subject to a limit which is proportional to the product of the elongation and the toroidal magnetic field. The elongation is made greater than about 4. The aspect ratio is preferably between about 3 and 10.
