Transit Stock:
The delivery lead-time from the plant to the DC is about one day. As the stock for this transport is not considered on the are, the minimum stock in the DC has to be increased by this amont. Whil the transportation link, there exists also inventory that is currently transported in-between. This stock component only depends on the transportation time and the demand because on average the inventory held on the truck equals the demand which occurs during the transportation time.

Ferroelectricity:
Ferroelectric phase transtition discovered in Li-substiuated ZnO ceramics in 1996. Because of the easy fabrication of good-quality thin films on Si, sapphire and glass substrates, ZnO is one promising material for ferroelectric integrated devices and optoelectronic devices. The replacement of host Zn atoms by substitutional Li atoms, which was confirmed by X-ray structural analysis, play ana important role for the appearance of ferroelectricity. The mechanism of this novel ferroelectric phase transition has not been well understood yet.

Ferrimagnetic Ceramic Materials:
Ferrimagnetic materials represent a class of ceramic materials that are widely used in high-frequency applications. They are divided in garnets and ferrites, the latter being much more important in shielding applications because of their larger values of the relaticve magnetic permeability and of their larger losses. Ferrites have a crystal structures and are sintered by means of various metal oxides, obtaining high values of the magnetic permability. Theese kidn of materials are usually further classified bas either soft or hard magnetic materials, but when their magnetizing source is removed, these materials lose their magnet-lke behaviour.

Extractives:
A large variety of wood components, although usually representing a inor fraction, are soluble in neutral organic solvents or water. They are called extractives. The extractives compreise an extraordinarily large number of individual compounds of both lipophilic and hypdrophilic types. The extractives can be regarded as nonstructural wood consituents, almost exclusively compsed of extracellular and low-moleculaweight compounds. Similar type of constituents are present in so-called exudates, which are formed by the tree through secondary metabolism after mechanical damage or attack by insects or fungi. Although there are similarities in the occurence of wood extractives within families, there are distinct differences in the composition even between closely related wood species.
